Before that, let’s discuss the problems with htpasswd + Basic Authentication.

The problem

What is an htpasswd File?

An htpasswd file contains a finite number of usernames and passwords encrypted using the highly secure bcrypt algorithm. The file looks like the following:

admin@mycompany.com:$2y$05$Npda/wcHOGrBKYgr9sNJo./O8KZbXQqwTrF0BcRxiS5Vr.P37zDJC
user@mycompany.com:$2y$05$crIQ3pU/dJi2T6c8IM1UNOXV6KlgxjvFBvJH2ZfmmhgRSS8qObZVu
another-user@mycompany.com:$2y$05$tQrvnJQgeroRwi8FJgHsUufUZpU3lrmoMMXC9xYZ9XA9Kno0iwDWy

Most of the time, the htpasswd file is used in conjunction with Basic Authentication. Basic Authentication works by sending a Base64-encoded username and password as an Authorization header in every request. On the server side, these credentials are validated against the htpasswd file.

Why Is This the Most Insecure Way to Handle Authentication?

Using htpasswd with Basic Authentication is considered highly insecure for the following reasons:

• Plain Username and Password Are Sent in Every Request
  • Although encoded in Base64, it is easily decodable.
• Lack of Session Management
  • There is no session handling; credentials are sent repeatedly with every request.
• Password Stored in Client-Side Cache as Plain Text
  • If the client device is compromised, cached credentials can be exploited.
• Exposure in Logs
  • Credentials can appear in browser history, server logs, and proxy logs, increasing the chances of leakage.
• No Logout Mechanism
  • There is no way to log out a user or invalidate credentials once they are compromised.

You might also have seen this method in use in legacy devices, such as older routers and network appliances.

The Objective

The htpasswd file is an excellent fit for applications with a finite number of users. If an application wants to leverage the flexibility of an htpasswd file but without relying on Basic Authentication, OAuth2-Proxy is the perfect solution for this use case.

OAuth2-Proxy creates a cookie-based session upon login and uses this cookie for subsequent authentication. The cookie has an expiration time and can be refreshed at regular intervals. It also includes built-in support for CSRF tokens, enhancing security.

The challenges

While there are various ways to replace Basic Authentication, we’ve chosen to address it using the open-source software OAuth2-Proxy. However, using OAuth2-Proxy comes with its own set of challenges:

• Focus on OIDC/OAuth2-Based Authentication
  • As the name suggests, OAuth2-Proxy primarily focuses on OpenID Connect (OIDC) and OAuth2 authentication methods.
  • By default, the application requires at least one OIDC provider to be configured.
  • There is no official support for disable provider https://github.com/oauth2-proxy/oauth2-proxy/issues/1725#issuecomment-1195865190
  • The htpasswd file-based authentication is optional and secondary.
• No Support for External Standalone Login Pages
  • OAuth2-Proxy includes a built-in login page, which can be customized. However, it is pure HTML and lacks advanced design capabilities.
  • If your application uses a ReactJS-based branded login page, it won’t be supported by default.

Solutions

There are two main approaches to address these challenges:

• Dummy OAuth2 Provider + Built-in Login Page.
• Dummy OAuth2 Provider + Standalone Login page.

The OAuth2-Proxy can be run as a http proxy to route traffic to the upstream. In this setup, the routing is handled by some well known proxy and OAuth2-Proxy act as a forward-auth.

with built-in login page

I’m a big fan of Traefik Proxy! Its Docker label-based configuration is on another level🔥in CNCF ecosystem. For this setup, I’ve chosen Traefik as the reverse proxy in front of OAuth2-Proxy.

The config of oauth2 proxy is look like

--client-id=dummy-client-id,
--client-secret=dummy-client-secret,
--cookie-expire=168h,
--cookie-name=_session,
--cookie-refresh=30m,
--cookie-secret=cbiGJkwts9Ye6XD2Pbt_L1jLcipIZBDMfMuqxDWRbeQ=,
--custom-sign-in-logo=https://avatars.githubusercontent.com/u/4029521?v=4,
--custom-templates-dir=/templates,
--cookie-secure=false,
--email-domain=*,
--footer=Powered by  href='https://mycompany.com'>My Company,
--htpasswd-file=/.htpasswd,
--http-address=0.0.0.0:4181,
--provider=google,
--proxy-prefix=/auth,
--reverse-proxy=true,
--set-authorization-header,
--set-xauthrequest,
--skip-provider-button=false,
--upstream=static://202

In this the client-id and client-secret are dummy values.

The Login page

The Cookie

The docker compose stack is in GitHub Repo

with standalone login page

In some cases, the login page also serve from the application. This is for, how to handle it.

Traefik Config

Remove the middleware for the /login and /static URL for app.

- traefik.http.routers.app-noauth.rule=PathPrefix(`/login`) || PathPrefix(`/static`)
- traefik.http.routers.app-noauth.entrypoints=web
- traefik.http.routers.app-noauth.priority=200

Added errors middleware to handle errors.

- traefik.http.middlewares.oauth2-proxy-error.errors.service=app@docker
- traefik.http.middlewares.oauth2-proxy-error.errors.status=401,403
- traefik.http.middlewares.oauth2-proxy-error.errors.query=/login

This is not working. TODO.

OAuth2 Config

The Login page written in Your Preferrable language.

The form POST request to /auth/sign_in

The Cookie

There is no difference in the cookie.

Final Thoughts

This solution eliminates Basic Authentication for your application using OAuth2 Proxy, making it ideal for newly developed software (Greenfield projects).

But what about the legacy devices and applications (Brownfield systems) in your network that have relied on Basic Authentication for decades? If you’re still accessing them using Basic Authentication, your system is at significant risk.

How can these systems be protected? This is a critical topic with plenty to discuss, which we’ll cover in detail in an upcoming post(coming soon).

Some time back I set up pi-hole on a Raspberry Pi in my home network to block advertisements.

~30% of my home internet traffic are tracking or advertisement. Now its all are blocked with #pihole pic.twitter.com/mRai9IBwgb

— arulraj.net (@arulrajnet) June 15, 2020

Now, I have reused it to block the internet for a specific device or domain.

My network

• The pi-Hole act as a DNS and DHCP server
• Main Router is just a WAN provider
  • Route 8.8.8.8, 4.4.4.4 and 8.8.4.4 traffic to 192.168.1.53
  • Youtube app or Android SmartTV doesn’t honor the DNS received via DHCP Offer.
  • Thats why route all the DNS traffic to pi-hole
• Extender is to widen the coverage

Use case

At our home, TV time for the kids is mostly reserved for weekends. But once they start watching, getting them to stop can feel like a never-ending struggle. Forget asking for the remote; that’s practically impossible!

I needed a foolproof way to ensure the TV goes off after a set time without any arguments.

The Pi-hole came for rescue.

Hack

A little bit background on Pi-Hole.

• Its a DNS server with the advertisement domains list.
• Whenever a device try to resolve those domains, it returns as 0.0.0.0
• Its also acts as DHCP server

We are going to use the following resources to block internet.

• Groups - Its for grouping clients
• Clients - Every MAC address in the network as client and assign the client to a Group
• Domains - Custom whitelist or blocklist the domains and assign to a Group.

These are the steps we are going to do

• Create a group.
• Create domain. Add the domain to block and add that domain to group.
• Create client and assign that client to group.

Create a Group. This will used to add the blocklist client.

Here I have created group called Block_Internet

To block all internet for the particular device

Add a new block list domain.

Domains → Regex Filter

Regular Expression: .* Comment: Block All Click Add to Blacklist

Once added, change the group to Block_Internet

Now add the client to the group.

In my case whenever the TV time got over, I will add the TV client into the list.

To block youtube

Add *.googlevideo.com domain to the regex filter.

Things to Improve on Pi-Hole

• Time based restriction or group assignment
• domain list support for this kind of use cases

Final Thoughts

All this blocking works perfectly—until the day they discover VPNs. For now, they’re too young to figure it out. To them, it’s just “Dad’s magic.” 😆

What official documentation says?

Most of you used this gvm . But this is doesn’t support for windows. So I have found this andrewkroh/gvm: Go Version Manager . Its supports windows as well.

If you are using powershell go with their documentation

[Net.ServicePointManager]::SecurityProtocol = "tls12"
Invoke-WebRequest -URI https://github.com/andrewkroh/gvm/releases/download/v0.5.2/gvm-windows-amd64.exe -Outfile C:\Windows\System32\gvm.exe
gvm --format=powershell 1.23.2 | Invoke-Expression
go version

But there is no documentation for Git bash.

How to do in Git Bash

Install

Open Git Bash.

This is for install gvm and install golang 1.18

mkdir -p ~/bin
curl -sL -o ~/bin/gvm https://github.com/andrewkroh/gvm/releases/download/v0.5.2/gvm-windows-amd64.exe
chmod +x ~/bin/gvm
gvm install 1.18

Setup default Golang

The following will auto add it in your .bashrc file. This will setup golang 1.18 as default.

cat << "EOF" >> ~/.bashrc
#
# GVM (Go Version Manager) https://github.com/andrewkroh/gvm
#
if which gvm > /dev/null; then
  if gvm list | grep -q "1.18"; then
    eval "$(gvm --format=bash 1.18)"
  fi
fi
EOF

To change Golang

To change the golang to 1.23 from 1.18 on runtime

Install 1.23 if not already installed

gvm install 1.23

To change

eval $(gvm use --format=bash 1.23)

• WhatsApp Web Way
• QR Code Way

WhatsApp Web

I am from Chennai, India. Here WhatsApp messenger app is widely used. So this app is installed by default.

We can access the messenger from PC via browser. web.whatsapp.com

In WhatsApp, you can chat against your own profile. You can use that for text copy and file transfer.

QR Code

Use any online QR code generator to copy text. Then scan it using your camera app. My personal favorite is zxing

Personally I don’t want to install any extra software/app in my pc or phone. That is the reason I am following this.

What is your way of doing this?

Why❓

By default, apisix depends on etcd for storing configuration.

But most of the time your upstream services are fixed. Not changed often. Then do we really need etcd for configuration. Maintain and managing etcd cluster is pain and money 💲

Here is the standalone mode to solve this.

🤔How ?

If you are geek, here is the Github repo for docker-compose example with full source code. Go there.

config.yaml

This file has the configuration as you do earlier

deployment:
  role: data_plane
  role_data_plane:
    config_provider: yaml

#END

Here the config_provider as yaml.

This has to be mounted as /usr/local/apisix/conf/config.yaml

apisix.yaml

This file is responsible for routes, services and upstreams. The file will be look like

routes:
  -
    uri: /*
    service_id: 1
services:
  -
    id: 1
    upstream_id: 1
upstreams:
  -
    id: 1
    nodes:
      "web1:80": 1
    type: roundrobin

#END

This has to be mounted as /usr/local/apisix/conf/apisix.yaml

docker-compose.yml

services:
  apisix:
    image: apache/apisix:3.10.0-debian
    environment:
      APISIX_STAND_ALONE: "true"
    volumes:
      - ${PWD}/apisix.yaml:/usr/local/apisix/conf/apisix.yaml
      - ${PWD}/config.yaml:/usr/local/apisix/conf/config.yaml
    ports:
      # Web - Proxy
      - 9080

The common areas where manual errors occur

• The mounting path of the files.
• The content of the files. The different content for different files.
• The #END line at the end of file.
• The environmental variable for apisix APISIX_STAND_ALONE: "true"

What is on the Repo?

There are two upstreams behind the APISix.

The URI / and /web1 forwards to the web1.

The URI /web2 forwards to the web2.

These routes, services and upstreams configured in apisix.yaml

I couldn’t find any direct example to create seed for user, account or cluster as like Golang or Java.

🐎Golang Example

From their source code to create new user seed

// Create a new User KeyPair
user, _ := nkeys.CreateUser()

// Access the seed, the only thing that needs to be stored and kept safe.
seed, _ := user.Seed()

// Access the public key which can be shared.
publicKey, _ := user.PublicKey()

☕Java Example

From their javadoc to create new user seed

The pseudo code for create user is look like

import io.nats.client.NKey;

NKey nkey = NKey.createUser(null);
System.out.println(nkey.getPublicKey());
System.out.println(nkey.getSeed());

The source code is in here

🐍Python Example

The source code is in here . But there is no reference to create user, account or cluster.

Their documentation talks about from a seed file how we can decode user. Doesn’t talks about create new one in anywhere.

So I have create an example for creating seed for different purposes.

First of all you have to install nkeys

pip install nkeys

Create User

Create seed for User

import nkeys
from nacl.signing import SigningKey

signing_key = SigningKey.generate().encode()

# Nats encoded seed for user
src = nkeys.encode_seed(signing_key, prefix=nkeys.PREFIX_BYTE_USER)

# Seed
seed = nkeys.from_seed(src).seed

# Private Key
private_key = nkeys.from_seed(src).private_key

# Public Key
public_key = nkeys.from_seed(src).public_key

Create Account

Create seed for Account

import nkeys
from nacl.signing import SigningKey

signing_key = SigningKey.generate().encode()

# Nats encoded seed for account
src = nkeys.encode_seed(signing_key, prefix=nkeys.PREFIX_BYTE_ACCOUNT)

# Seed
seed = nkeys.from_seed(src).seed

# Private Key
private_key = nkeys.from_seed(src).private_key

# Public Key
public_key = nkeys.from_seed(src).public_key

Create Cluster

Same way just change the prefix for others

Create seed for Cluster

# Nats encoded seed for cluster
src = nkeys.encode_seed(signing_key, prefix=nkeys.PREFIX_BYTE_CLUSTER)

Create Server

Create seed for Server

# Nats encoded seed for server
src = nkeys.encode_seed(signing_key, prefix=nkeys.PREFIX_BYTE_SERVER)

Create Operator

Create seed for Operator

# Nats encoded seed for server
src = nkeys.encode_seed(signing_key, prefix=nkeys.PREFIX_BYTE_OPERATOR)

You can find all the prefix in their source code.

💡How I found

I am always a believer of the show me the code principle. Also we learn more by seeing others code.

In this code they do padding with given binary array. Also they check the first byte against the predefined byte. Its all start from there.

📖 Learnings in the process

• As you know the keys used by NATS are ED25519. There is an python lib for that
• Python Nkeys earlier used that only and they switch over to PyNacl. Since the above lib is not working with latest Python.
• Lot of the things get from their PyNacl doc
• Got to know about nats-box docker and nsc command line binary tool available to create creds file and other stuff.
• The output of seed, private and public key starts with specific prefixes

The requirement

Here is the example about how we can use a single YAML file for docker services and configuration. We don’t need separate file or folder maintained in the repo. Just single docker-compose.yml file is enough. All the configuration is with in that as inline content.

Lets dive into the topic.

• We want to deploy a nginx proxy.
• Its has a configuration file.
• It has HTML file to serve.
• It has a image file to serve.

Single YAML

How I can define the inline config file

configs:
  nginx.conf:
    content: |
      your config file content

Refer this doc in GitHub.

Here is the compose yaml file for nginx serve the html file content.

name: nginx-inline
services:
  nginx:
    image: nginx:1.27.1
    ports:
      - 8080:80
    configs:
      - source: index.html
        target: /usr/share/nginx/html/index.html
configs:
  index.html:
    content: |
      

      
        
          
          
        
        
          

            Hello arulraj.net!
          
        
      

Bring up the system using docker-compose up -d. Then access http://localhost:8080

Now you see the page like this.

The index.html loaded successfully.

Environmental interpolation

You can do the environmental interpolation in docker-compose.yml file in a usual way.

• The good old .env file
• OR use export before ran docker-compose up -d

The following content has WELCOME_MESSAGE in the index.html

configs:
  index.html:
    content: |
      

      
        
          
          
        
        
          

            ${WELCOME_MESSAGE:-Hello, World!}
          
        
      

Then

export WELCOME_MESSAGE="Hello, Arul!"
docker-compose up -d

Store environmental variable as config file

Expose the host machine environment variable inside the container as config file.

name: nginx-inline
services:
  nginx:
    image: nginx:1.21.1
    ports:
      - 8080:80
    configs:
      - source: path.txt
        target: /usr/share/nginx/html/path.txt
configs:
  path.txt:
    environment: "PATH"

Here we expose the host machine PATH env as path.txt

Binary file

The binary file converted as base64 and can be used.

But this is not supported in compose spec as like kubernetes.

Will update this post once its supported.

First I have found below from Reddit

PyInquirer

Its fits my requirement. But it seems not maintained. So searching for other alternatives.

Found the below awesome list

Awesome CLI Frameworks in python

Then short listed these

• Python Prompt Toolkit
• PyInquirer
• InquirerPy
• Questionary

My intuition says, I am mostly go with Questionary . Lets see. Will update the post after completed.

Got to know about

• Text User Interface - TUI
• Seems python prompt toolkit is most widely used and actively maintained.
• Inquirer.js for NodeJS
• Cobra for Golang

Created Git CLI list.

These can be used install docker with in docker.

Why fig alias?

The docker-compose project was originally named fig as an open-source initiative. After Docker acquired it, the project was renamed to docker-compose.

Refer this commit

I don’t want to install Android Studio. Just want to setup Android SDK and build using Gradle. If you have these kind of niche requirement then this article for you.

I am using GitBash on windows. The steps will work on other operating system as well with minor tweaks.

🥎Install SDK

mkdir -p $HOME/portable/android-sdk

Then Add the ANDROID_SDK_ROOT in .bashrc

tee -a ~/.bashrc <<"EOF"
export ANDROID_SDK_ROOT="$HOME/portable/android-sdk"
export PATH="$PATH:$ANDROID_SDK_ROOT/cmdline-tools/bin:$ANDROID_SDK_ROOT/platform-tools"
EOF

Cmdline and Platform tools

Download the cmdline-tools and platform-tools. Then extract those inside the folder

curl -L https://dl.google.com/android/repository/commandlinetools-win-11076708_latest.zip -o $HOME/portable/android-sdk/cmdlinetools-win.zip

curl -L https://dl.google.com/android/repository/platform-tools-latest-windows.zip -o $HOME/portable/android-sdk/platform-tools.zip

Extract

unzip $HOME/portable/android-sdk/cmdlinetools-win.zip -d $HOME/portable/android-sdk/
unzip $HOME/portable/android-sdk/platform-tools.zip -d $HOME/portable/android-sdk/

Install Android 30. This app requires this platform version.

cd $HOME/portable/android-sdk/
./cmdline-tools/bin/sdkmanager --sdk_root=${PWD} --list
./cmdline-tools/bin/sdkmanager --sdk_root=${PWD} --install "platforms;android-30"
./cmdline-tools/bin/sdkmanager --sdk_root=${PWD} --install "build-tools;30.0.3"
./cmdline-tools/bin/sdkmanager --sdk_root=${PWD} --list_installed

Now you have successfully installed Android SDK in your PC.

To Get the latest zip or file for other Operating Systems from here

To download Command Line Tools Only

To download Platform Tools

If you want to uninstall particular version

./cmdline-tools/bin/sdkmanager --sdk_root=${PWD} --uninstall "platforms;android-30"
./cmdline-tools/bin/sdkmanager --sdk_root=${PWD} --uninstall "build-tools;30.0.3"

🛠Build App

Now I just clone the above app. Then

gradle bundle

Then you can find the apk files in Water-Reminder/app/build/outputs/apk/

📱Connect Your Phone

In Your phone

• Settings → About Phone → Build number → Tab 7 times
• Then Setting → Developer Options → Enable USB debugging

Then connect your phone via USB

./platform-tools/adb devices -l

Now its should list your device.

⛓Install App

To install using adb

./platform-tools/adb install /path/of/app-debug.apk

To install using gradle

gradle installDebug

🐛Issues faced

Try to build the app with android 31

Initially I tried with the platform version android-31 since my mobile Android version is 12. You can find the mapping here

Changed the compileSdkVersion, buildToolsVersion and targetSdkVersion in build.gradle

    compileSdkVersion 31
    buildToolsVersion "31.0.0"
    defaultConfig {
        applicationId "io.github.z3r0c00l_2k.aquadroid"
        minSdkVersion 21
        targetSdkVersion 31

While building the app with that version I got the following error.

Build-tool 31.0.0 is missing DX at android-sdk\build-tools\31.0.0\dx.bat

The fix for this is

cd $HOME/portable/android-sdk/build-tools/31.0.0/
ln -s d8.bat dx.bat

cd $HOME/portable/android-sdk/build-tools/31.0.0/lib/
ln -s d8.jar dx.jar

After this gradle build got success.

Refer Github issue . There is a issue in both 31 and 32 version of tools.

Cannot install without signing

Initially try to install normal APK. Its not installed and got error. Debug build solves that problem

Different Notification tone for this app

Since its a water reminder app. I want to send different notification sound for this. To do that.

Settings → Apps → All apps → Water Reminder

Click on the Notification Channel. Then select the sound in that

Before uninstalling, list the package with the name.

There is two packages with the same name “WhatsApp Web”. But the Id and Version are different.

Use winget list to get all the installed packages.

Error on uninstall with specific version

Tried this

winget uninstall --name "WhatsApp Web" --version "1.0.0.0"

Got the following error

Multiple installed packages found matching input criteria. Please refine the input.

Error on uninstall with Id

Tried this

winget uninstall --name "WhatsApp Web" --id MSIX\web.whatsapp.com-6EC4871F_1.0.0.0_neutral__910631y4v73xw

Got the following error

No installed package found matching input criteria.

The Fix

We have to escape the backslash ()

winget uninstall --name "WhatsApp Web" --id MSIX\\web.whatsapp.com-6EC4871F_1.0.0.0_neutral__910631y4v73xw

Now its uninstalled successfully.

❓ Why no post ?

• Why should I write this as blog post ?. Just twitter/x post is sufficient right?
• Does this really helpful to someone ?
• Its just a small thing, just a little effort anyone can get to know themselves.
• Does my employer like it or not ?
• blah.. blah.. blah..

A little bit background, In the past decade

• Get married and Got two kids. More responsibility and I really enjoy spend time with my family.
• I work for an organization called IoTium Systems Private Ltd., I really love what I am doing there.

Its been really hard to find time for this apart form Family + Work 😃

⏰ Why now?

Recently I went through a minor surgery. Nothing to worry. But, It made me think in multiple dimensions.

• Writing is clear my thoughts.
• Its for me. Not for anyone.
• Everything has my perspective even its small thing.
• As long as not exposing confidential information, its fine.

Also I am big believer of Gandhian Thoughts.. Here are some of quotes related to that

கைகளால் ஒன்றை உருவாக்குபவன் தன் அகத்தை அதன் வழியாகச் சீரமைத்துக் கொள்கிறான். - காந்தி

English Translations are

Who builds something with his hands aligns his inner self through it. - Gandhi

Even in the simplest way you can rock the world. - Gandhi

The another mantra I learned is Dedicate🧑‍🤝‍🧑. Even though 10/20% less in quality its fine. Empower the others.

🎆 What next?

FYI, I quit social media long back except twitter and reddit. Even though I am not write on internet. I write a lot as confluence pages, JIRA comment and PR comments. I have been expert in many things in these days. When I look back I have been deep understanding of many things, The first principles. So I want to write those things.

In this setup I am going to serve 1x1 pixel using nginx server.

Install nginx

sudo apt-get install nginx -y

Configuration

changing /etc/nginx/nginx.conf as below

user nginx;
worker_processes 4;

error_log  /dev/stdout;
pid        /var/run/nginx.pid;

events { worker_connections 1024; }

http {

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

      access_log  /dev/stdout;

TNEB Usage permlink Form

How its works

• For example, the service no is 265 / 005 / 1234
• It will take your service no and do base64 of "TANGEDCO||1234" is VEFOR0VEQ098fDI2NXx8MDA1fHwxMjM0
• Then base64 of Region(09) is OQ==
• Then finally URL is http://tneb.tnebnet.org/newlt/consumerwise_gmc_report.php?encserno=VEFOR0VEQ098fDI2NXx8MDA1fHwxMjM0&rsno=OQ==

You are a hardcore cricket fan, want to get updated the score while working 😄 😄 . But bored to open a browser ⇒ goto cricinfo ⇒ goto particular cricket match. Welcome, this script for you only.

Why this Script..?

I am not the fan of cricket. But some of friends working as Linux Administrators who is always looking black and white terminal, They want to know the score. So I wrote a shellscript to get score from cricinfo. Now they happily run this script in an another terminal and gets updated about score.

How to use..?

• Download the file from github livecricketscore.sh
• Then copy that file in to /usr/bin/ folder
• Run that livecricketscore from anywhere
• It will ask for the which match score you want to know
• Select the matcher number
• It will continuously run untill you kill ( CTRL + C ) that

wget --no-check-certificate https://gist.githubusercontent.com/arulrajnet/fb71169c35180f9d9abd/raw/livecricketscore.sh
chmod +x livecricketscore.sh
cp livecricketscore.sh /usr/bin/livecricketscore
sh /usr/bin/livcricketscore

You need to install xmllint if its not there already. To install xmllint in ubuntu

apt-get update
apt-get install libxml2-utils

Credits

Thanks to ww.espncricinfo.com . I am using their RSS feed to list the live matches and get the score.

Hope you know what is TOR and Privoxy.

Github Repo https://github.com/arulrajnet/torprivoxy

Docker Repo https://registry.hub.docker.com/u/arulrajnet/torprivoxy

How to Use

You have to install docker first. To install in linux follow this

docker run -d \
-p 8118:8118 -p 9050:9050 -p 9051:9051 \
--name tor -i arulrajnet/torprivoxy:latest

Binding port 9050 and 9051 are optional. 9051 is the controlport of TOR Network. Using that you can forcefully regenerate the TOR ip. Read more about tor_ip_renew.py

Docker Tags

There are two flavor of container

Tag Base Image Size

latest debian:wheezy 180 MB

wheezy debian:wheezy 180 MB

jessie debian:jessie 228.1 MB

This is the very lean image for TOR with Privoxy currently available in docker hub.

Verify

How to cross check are you getting ip from Tor or not.

Check your IP without TOR

curl http://curlmyip.com

Check with TOR

curl -v --socks5-hostname localhost:9050 http://curlmyip.com

Check with privoxy

export http_proxy=http://localhost:8118/
curl http://curlmyip.com
unset http_proxy

or

curl -x http://localhost:8118 -L http://curlmyip.com

Debug

If the above step is not success you have to verify the log files.

docker exec -it tor /bin/bash

All the log files in the /tmp folder of container.

To restart TOR and Provoxy

supervisionctl
supervisor> status
supervisor> restart tor
supervisor> restart privoxy

Global Proxy

You can set privoxy as a global proxy so that all your traffic goes via TOR

In Ubuntu

Open /etc/environment

http_proxy="http://127.0.0.1:8118"
https_proxy="http://127.0.0.1:8118"
ftp_proxy="http://127.0.0.1:8118"
HTTP_PROXY="http://127.0.0.1:8118"
HTTPS_PROXY="http://127.0.0.1:8118"
FTP_PROXY="http://127.0.0.1:8118"
_JAVA_OPTIONS="-Dhttp.proxyHost=localhost -Dhttp.proxyPort=8118"

Add this at the EOF.

Then source /etc/environment

In CentOS

Create file /etc/profile.d/proxy.sh Then put the below content and save.

http_proxy="http://127.0.0.1:8118"
https_proxy="http://127.0.0.1:8118"
ftp_proxy="http://127.0.0.1:8118"
HTTP_PROXY="http://127.0.0.1:8118"
HTTPS_PROXY="http://127.0.0.1:8118"
FTP_PROXY="http://127.0.0.1:8118"
_JAVA_OPTIONS=$_JAVA_OPTIONS" -Dhttp.proxyHost=localhost -Dhttp.proxyPort=8118"

export http_proxy https_proxy ftp_proxy HTTP_PROXY HTTPS_PROXY FTP_PROXY _JAVA_OPTIONS

Then source /etc/profile.d/proxy.sh OR you can set the same in .bashrc or .bash_profile

What is the real issue..?

First you should to know all jetbrains IDE's are written in Java. The issue because of your pycharm needs more memory to process your projects and files at the backend Java requires memory. But its not able to acquire that much of memory. So its closed obtrubtly.

Everyone will say increase the JVM/Java max heap size in pycharm.properties file. Then restart the pycharm. But thats not a permanent solution.

The real problem is pycharm internally uses 32bit jvm which comes with the installer package. The 32 bit JVM can allocate maximum 2GB of space only.

What is the solution for it..?

So the fix is you have to start your pycharm with 64bit JVM. Here we will see how to start with 64bit JVM. Three steps to fix that

• Set the 64bit SDK as environmental variable
• create properties for 64bit version
• start the ide from .bat file

Set 64Bit SDK:

Before setting environmental variable you have to find out which version of java you are using. To find out Open Command Prompt → Then run the below command

java -version

It should have the "Java Hotspot(TM) 64-Bit Server" line in the output. If there is no Bit information then its 32bit java. Then proceed furthur you have to download and install the 64bit JDK from http://java.com/

Then open Control Panel → Edit Environmental Variable for Your Account

In User variables set PYCHARM_SDK and path will be your 64 bit java version

Create properties file:

For 64bit you have to create separate properties file for that.  Create file named as pycharm64.exe.vmoptions in the root directory of IDE

-server
-Xms256m
-Xmx2048m
-XX:MaxPermSize=512m
-XX:ReservedCodeCacheSize=128m
-ea
-Dsun.io.useCanonCaches=false
-Djava.net.preferIPv4Stack=true
-Djsse.enableSNIExtension=false
-XX:+UseCodeCacheFlushing
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=100

To start:

IDE should start with the pycharm.bat file.

This fix will work for other IDE such as WebStrom, PhpStrom, IntelliJ and RubyMine from jetbrains also.

Basically you have to create 64.exe.vmoptions file. Set the 64bit Java environmental variable for that IDE. Then start the .bat file

Environmental Variable for Different product:

• IDEA_JDK for IntelliJ IDEA
• WEBIDE_JDK for PhpStorm and WebStorm
• PYCHARM_JDK for PyCharm
• RUBYMINE_SDK for RubyMine

To know about what environmental variable have to use, open .bat file. Then you will get to know.

Pentaho Data Integration Tool (PDI) is mainly used for Extraction, Transformation, Load (ETL). They have their own components to do basic and advanced ETL operations.

Install

• Download and Extract of Community edition of PDI.
• Extract the downloaded zip file as data-integration.
• You need Java in your machine for PDI Tool to run.
• To run PDI open spoon.bat in windows.

Here PDI / Pentaho Data Integration Tool / Spoon / Kettle all are mean same.

You can run your own java code as a component in the ETL flow. For that have the component called User Defined Java Class. Absolutely you will use external classes or jar's in your java component. In this post will guide you to load those external jar's while pentaho loads.

Configure

• Create libext folder with in data-integration.
• Backup your launcher.properties file with in data-integration/launcher folder.
• Then save below as launcher.properties in that folder

main=org.pentaho.di.ui.spoon.Spoon
libraries=../test:../lib:../libswt:../libext
classpath=../:../ui:../ui/images:../lib:../libext

system-property.pentaho.installed.licenses.file=${PENTAHO_INSTALLED_LICENSE_PATH}

• Now copy your external / third party jars into libext folder
• Now start the spoon.bat

My setup

OS - Windows 7 64 bit

Java - Java 1.7.0_45 64 bit

PDI - pdi-ce-5.1.0.0-752.zip

Note

Before adding any jar into libext have a look into data-integration/lib. If the jar is already there you can directly use that.

Using user defined class in your flow leads to increase your process time. So use that if you really need it. Refer https://twitter.com/arulrajnet/status/514792905127370752

In earlier days (while SUN), Installing JRE / JDK in a VM is very easy process just like extracting a file and use it. Now wget-ing the source file itself a bit long process. After that you have use few commands to set this newly installed Java as default Java. So I have came up with list of steps to make installing java easier in CentOS and Ubuntu.

Downloading JDK...?

In VM's usually you get terminal not GUI. So I followed command way in this tutorial. You have to add cookies to download java via wget command.

For CentOS

wget --no-cookies --no-check-certificate \
--header "Cookie:gpw_e24=http%3A%2F%2Fwww.oracle.com%2F;oraclelicense=accept-securebackup-cookie" \
http://download.oracle.com/otn-pub/java/jdk/7u55-b13/jdk-7u55-linux-x64.rpm

For Ubuntu

wget --no-cookies --no-check-certificate \
--header "Cookie:gpw_e24=http%3A%2F%2Fwww.oracle.com%2F;oraclelicense=accept-securebackup-cookie" \
http://download.oracle.com/otn-pub/java/jdk/7u55-b13/jdk-7u55-linux-x64.tar.gz

I wrote a python script to download the Oracle Java jdk / jre from terminal.

That script in https://gist.github.com/arulrajnet/7b261203499375bd0759

How to Use

wget --no-check-certificate https://gist.github.com/arulrajnet/7b261203499375bd0759/raw/download_java.py
chmod +x download_java.py
python download_java.py

It will ask for the type of package you want to download and version of package want to download. Finally the selected file will be downloaded in the current directory

Installing and Setting...?

In the installation to make this java as default one in the system wide.

For CentOS

rpm -Uvh jdk-7u55-linux-x64.rpm
alternatives --install /usr/bin/javaws javaws /usr/java/latest/bin/javaws 2
alternatives --install /usr/bin/java java /usr/java/latest/bin/java 2
alternatives --install /usr/bin/javac javac /usr/java/latest/bin/javac 2

For Ubuntu

sudo mkdir -p /usr/java/jdk1.7.0_55
sudo tar -xzvf jdk-7u55-linux-x64.tar.gz -C /usr/java/
sudo ln -s /usr/java/jdk1.7.0_55/usr/java/latest
sudo ln -s /usr/java/latest /usr/java/default
sudo update-alternatives --install /usr/bin/javaws javaws /usr/java/latest/bin/javaws 2
sudo update-alternatives --install /usr/bin/java java /usr/java/latest/bin/java 2
sudo update-alternatives --install /usr/bin/javac javac /usr/java/latest/bin/javac 2

For ubuntu there is a PPA released by webupd8team.

PPA way

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer

Note: But that is not working since 16th March. Hope they fixed now.

Installing JRE...?

To install JRE the downloading links only different. The other commands are same. Here I had some direct links for different versions of JDK and JRE

JRE 1.7 ( 64 Bit )

http://download.oracle.com/otn-pub/java/jdk/7u55-b13/server-jre-7u55-linux-x64.tar.gz

http://download.oracle.com/otn-pub/java/jdk/7u51-b13/server-jre-7u51-linux-x64.tar.gz

Hope you know about openssl heartbleed bug. Don't know about, no problem go through it http://heartbleed.com/ . The point here is you should upgrade your openssl. Because of this bug all linux variants release the patch for openssl. Here the steps for upgrade openssl both ubuntu and centos.

How to find I am using affected version...?

In ubuntu:

Run this command

openssl version -a

There you can find "built on" date. If that date is older than Apr 7. Then you are using older version. You should upgrade your version.

OpenSSL 1.0.1 14 Mar 2012
built on: Wed Jan 8 20:45:51 UTC 2014

In CentOS:

Same as above.

How to upgrade openssl..?

In Ubuntu:

sudo apt-get update
sudo apt-get install libssl1.0.0 openssl -y

In CentOS:

sudo yum update
sudo yum update openssl -y

How to check am I upgarded..?

openssl version -a | grep built

The date should greater than or equal to Apr 7.

Hey..!!! you are done. Happy secure linuxing... 😄

Nowadays video on demand application available in latest red5 servers. The vod webapp is not available in  old version less than red5-1.0.0. Here I will give you the link to download for vod app for older red5.

Download vod webapp vod.zip

• Download the above zip file
• Extract the zip file
• Copy the vod folder into webapps folder of your red5
• Start the server

Note: This app only works with 0.8.0, 0.9.0 and 0.9.1 versions of red5.

I found a useful third party actionscript libraris from githup https://github.com/turbosqel. I mostly used these as3SupportLib and ASML lib all of my flex projects. But initially I were struggle to find out the example over the internet. So I am writing here one of the feature of that libraries. 

I am going to explain how to assign value to some variables from remote xml.

[View Source Enabled]

Below code snippet for loading xml from server using as3SupportLib

protected var configResource:Resource;

protected function onLoadAgain(event:MouseEvent):void
{
    configResource = ResourceManage.setExternal("config.xml");
    DownloadManager.addEventListener(DownloadManagerEvent.COMPLETE, onDownloadComplete);
}

The below code snippet for XML to Object

private function onDownloadComplete(event:DownloadManagerEvent):void
{
    var configXml:XML = new XML(configResource.loaderInfo.source);
    var xmlResult:Array = ASMLManager.parseXML(configXml,this);
}

For that works that config.xml should be written in certain way. Here is the doc for how to write xml https://github.com/turbosqel/ASML/blob/master/README.textile

My XML is here http://files.arulraj.net/code/flash/example/ASMLExample/config.xml

Now we are going to learn about how to unlock huawei datacard / dongle / modem. This is totally free. You are going to unlock by yourself without paying any single penny of yours. Some websites claiming money for this. Do not follow them. You can do by yourself without anyone help. Believe in yours. 😄

Why we need to unlock..? what is the use of that..?

If you are bought this device from any internet service provider they locked that device with particular network SIM. So you can't use any other network with this device. If you unlocked that device you can enjoy 3g with any SIM.

I bought this device e303s from Aircel in chennai for Rs.1600 - 3 month - 6GB - prepaid

What is needed to unlock..? Its hard to get one..?

Basically you need an unlock code for that. Earlier huawei modems are using different algorithm. That is easy to hack. Even some software tools available to find out the code. Now all modems follow new algorithm.

How can I found my device follows new algorithm or old algorithm..?

If you modem IMEI starts with 86** .Then that is the new algorithm. This tutorial for new algorithm modems only.

How to get the unlock code of modem..?

There are two ways to get your unlock code. Be prepared with your IMEI no of device.

First one:

Post your IMEI no in this forum thread http://forum.gsmhosting.com/vbb/f88/huawei-unlock-codes-request-only-here-v3-1707247/index100.html . You can get your unlock code instantly. Below is mine.

Second one:

Follow this link http://huaweicodecalculator.com/new-algo/

• Login with your Google account
• Give your IMEI no and model then press calculate button
• Then G+1 that (similar to like in FB)
• Then it will show your unlock code. Below is mine
• Use NEW ALGO CODE if your IMEI start with 86* (For e303s use New Algo code)

So I got the unlock code what next..?

Download Below files

• Mobile Partner - Mobile Partner.zip
• Dashboard Update - UTPS23.001.07.04.910_mobile_partner_dashboard_update.zip

Steps:

• Extract Mobile Partner and run setup.exe
• Open Mobile partner Once installation done.
• Plug the unsupported SIM in your datacard
• Plug your datacard into PC
• Now you can see the popup for enter unlock code.

Then enter your code and press Ok. wait for sometime. Now it will detect your new network. If not try again.

Note: You can attempt only 10 times.

Now you can enjoy with any network. I tested with Tata DoCoMo, BSNL, AirTel and Vodafone

Yeah you are done...!!!! Congrats Mate...!!!

Now what next..? (OPTIONAL)

Yes. If you want to remove the aircel default dashboard with in your data card follow this.

You are unlocked your device but still aircel dashboard within your device. So aircel dashboard will be installed while you freshly connected with any machine. Now we are going to change that to Huawei Mobile partner dashboard. This is purely optional.

I am using vmware player for last several years. But I am not tested their shared folder features. To share your host os folder with vm you have to install "vmware tools" on guest os. Installing vmware tools is very simple.

Checking vmware module :

sudo lsmod | grep vmhgfs

It should return some values something like shown on image.

List modules

If not you have to install vmware tools.

Installing vmware tools :

• Goto Player → Manage → Install vmware Tools . Now Vmware Tools is mounted as CDROM with in VM

Install VMware Tools

• Extract Your VmwareTools-9.2.0-799703.tar.gz file to somewhere.
• Goto "vmware-tools-distrib" folder path in terminal
• Then run this command "./vmware-install.pl"
• Just press enter for all the questions asked while installing

Vmware Install

Add shared folder for VM:

• Goto Player → Manage → Virtual Machine Settings
• In Options tab you can find the Shared Folders

Shared Folder

• Then reboot your machine

Auto mount shared folder on startup:

Finally I came back to point. After restarted the shared folder are not shown with in "/mnt/hgfs/" folder. So here is the fix for that.

There is a startup script called "open-vm-tools" with in /etc/init.d/ folder. Just add the below line in the start function.

mount -t vmhgfs .host:/ /mnt/hgfs

Then restart the service "sudo service open-vm-tools restart".

open-vm-tools startup

My Environmental :

| Product : Vmware Player version 5.0.0 build-812388 | Vmware Tools: VmwareTools-9.2.0-799703 | Guest OS : Ubuntu 12.04 LTS 32 bit | Host OS : Windows 7 64 bit

After a long time I came with a new post in flex. Yes fullscreen in flex..!!! Fullscreening a whole app is very simple. You can full screening by simply changing the display state of your application. But it will be tricky if you are try to fullscreen a particular component in an application. In this post I am taking videodisplay component in a video chat application.

Still you can fullscreen a component using fullScreenSourceRect property of stage.

stage.fullScreenSourceRect = new Rectangle (0,0,320,240);

But It is like zooming a component. Its not good such as videodisplay component. So I came up with an idea. Here its

• Get that object of element which you are going to make fullscreen.
• Remove it from parent object.
• Add that element into stage.
• Then resize that element to stage width and height.
• While existing from fullscreen remove from stage and add back to parent component.

protected function fullScreenButton_clickHandler(event: MouseEvent): void {
 var liveVideo: Object = liveVideoDisplay.getChildByName("liveVideo");
 videoBox.removeElement(liveVideoDisplay);
 stage.addChild(liveVideoDisplay);
 stage.displayState = StageDisplayState.FULL_SCREEN;
 liveVideo.width = stage.width;
 liveVideo.height = stage.height;
 stage.addEventListener(FullScreenEvent.FULL_SCREEN, fullScreenHandler);
}

FAQ:

Most of the default applications are not available..?

Yes. Most common application like Gmail, Maps, youtube are not there. You need to download and install from market.

I want to root my phone..?

No need. By default its rooted :)

After upgraded FM is not working..?

This is a bug in this firmware.

How to revert back to Original..?

Simple. Follow this post http://www.arulraj.net/2011/08/upgrade-samsung-galaxy-5-and-3-to-froyo.html

Reference: http://madteam.co/news/2012/05/guide-cyanogenmod-installation-guide-for-galaxy-5/

update 11th Sep 2012:

• Firmware download links updated
• For latest Google apps http://goo.im/gapps/

Why multiple instances..?

If you are a developer its for you. Sometimes you need to test your application with different type of data (like QA, Production) to replicate some error and etc., At that time no need to drop your old database and put the new one. Just use this and change the db port in your application configuration. This will be helpful for system administrators also to provide database service to his users.

Requirement:

• mysql installed windows machine
• Administrative privileges for that machine

For me mysql installed location is e:\softs\mysql\

Steps:

Create [instances\production] with in mysql installed directory (you can create anywhere). Better do everything in command prompt. 

e:
cd \softs\mysql\
md instances\production

Copy your data and share folder to production folder

copy data instances\production\
copy share instances\production\

To create your custom ini file copy my.ini file and edit

copy my.ini instances\production.ini

Edit Production.ini

• change port as 3307 under [client] and [mysqld] section
• Change basedir and datadir in that ini file

Click Here for my production.ini file

Now add your custom ini in system starup

mysqld --install mysqldproduction --defaults-file="E:\softs\mysql\instances\production.ini"

Now goto Control Panel → Administrative tools → Services. Then search for 'mysqldproduction' and start service.

OR

net start mysqldproduction

You may think all is done. But after this only I faced problems.

Cannot find the file specified:

When I try to start that service "System error has occurred. The system cannot find the file specified."

There is registry changes needed to fix that issue

• To open registry editor Start → Run
• Type 'regedit' and enter.
• Next, browse to the registry key named: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\mysqldproduction\ImagePath
• Now you can see there is no double quotes in that --defaults-file so change ImagePath to

"E:\softs\mysql\bin\mysqld" --defaults-file="E:\softs\mysql\instances\production.ini" mysqldproduction

Now start that service.

Keep watching Event Viewer. That is the best place to get debug information. Again I am getting error while starting server

Can't find messagefile:

The error is

System error 1067 has occurred.
The process terminated unexpectedly.
Can't find messagefile 'E:\softs\mysql\instances\production\share\errmsg.sys'

Fix:

Just copy errmsg.sys file from [MYSQL_BASE]shareenglishto that instancesproductionshare folder

Now everything is fine. Service will start successfully.

Before we start, some prerequisites for reader.

• How Spring MVC works. tutorial
• Basic knowledge about red5.

Then only you can understand clearly 😄 . If you don't have, no worries. Having knowledge in core java and servlet is enough

Day by day I experienced in Red5. I will explain a useful enhancement about red5. Let's start...

Red5 is an open source flash media server. If your webapplication is in the same server you can build some interesting streaming apps by binding your webapp and red5app. But you can not use red5 as a web application server, because by default RTMPServlet support macromedia-fcs (application/x-fcs) content type not http. But Internally Red5 uses Tomcat and Spring. By simple tweaks you can add http support for your red5 application.

So I add my own Red5DispatcherServlet in red5app web.xml to handle http request.

add this in your web.xml

  red5Demo-web
  com.demo.web.servlet.Red5DispatcherServlet
  
    contextConfigLocation
    /WEB-INF/red5Demo-dispatcher-servlet.xml
  

All configurations files in https://github.com/arulrajnet/red5Demo/tree/master/java/webapp/WEB-INF

You can use the default spring mvc DispatcherServlet. But problem is you can't access the red5 context from your controller. It means all objects loaded by red5 ContextLoggingListener can't be accessble from your web context. Did you understand...?

ok. Usually spring DispatcherServlet creates one web context and sets parents as ApplicationContext loaded by spring mvc ContextLoaderListener. Did you notice in red5app web.xml file we are using red5 own context loader listener. So if you use Spring mvc DispatcherServlet there is no parent context.

To override this we have to set red5 ApplicationContext as DispatcherServlet parent context. For that only I have some customization

Red5DispatcherServlet.java

package com.demo.web.servlet;

import org.red5.logging.Red5LoggerFactory;
import org.slf4j.Logger;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;
import org.springframework.web.servlet.DispatcherServlet;

public class Red5DispatcherServlet extends DispatcherServlet {

  private static final long serialVersionUID = 1L;

  private static final Logger LOG = Red5LoggerFactory.getLogger(Red5DispatcherServlet.class, "red5Demo");

  private WebApplicationContext parentContext;

  @Override
  protected WebApplicationContext initWebApplicationContext() {
    WebApplicationContext wac = null;
    parentContext = WebApplicationContextUtils.getWebApplicationContext(getServletContext());
    if (parentContext == null) {
      parentContext = (WebApplicationContext)
      getServletContext().getAttribute(
      WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE);
    }
    if (parentContext == null) {
      LOG.error("No web application context found.");
    } else {
      wac = createWebApplicationContext(parentContext);
    }

    setDetectAllHandlerAdapters(Boolean.TRUE);
    setDetectAllHandlerMappings(Boolean.TRUE);
    setDetectAllHandlerExceptionResolvers(Boolean.TRUE);
    setDetectAllViewResolvers(Boolean.TRUE);

    onRefresh(wac);

    String attrName = getServletContextAttributeName();
    getServletContext().setAttribute(attrName, wac);
    if (this.logger.isDebugEnabled()) {
      this.logger.debug("Published WebApplicationContext of servlet '" + getServletName() + "' as ServletContext attribute with name [" + attrName + "]");
    }

    return wac;
  }

  public WebApplicationContext getParentContext() {
    return parentContext;
  }

  public void setParentContext(WebApplicationContext parentContext) {
    this.parentContext = parentContext;
  }
}

Then define your handlers and view resolvers in red5Demo-dispatcher-servlet.xml

I have created one demo application for red5 with spring mvc. please refer github red5Demo https://github.com/arulrajnet/red5Demo

To Download this code

Install Git then run the below command.

git clone git@github.com:arulrajnet/red5Demo.git

I will write a separate post for setup red5 development environment and how to build that app.

Gnome2 Linux mint desktop

First I explain the whole story.. 😄

Why linuxmint in ubuntu...?

In the latest Ubuntu 11.10 release canonical team upgraded from Gnome2 to Gnome3 and ubuntu unity as a default login shell. But I am not comfortable with unity and gnome3. Here its a good article about why I don't like this read it. So I need Gome2 back thats why I installed linuxmint shell a.k.a mate shell.

How I installed linuxmint in my ubuntu..?

Its simple. I followed this tutorial.

Now why you want to uninstall..?

Now again, after installed mate shell facing some problems.

• ubuntu software center is not working.
• every gnome settings showing in two times.
• ubuntu gnome2 and mate have lot of difference.

Ok. How to unistall mate shell..?

For everything you need sudo permission. Login in unity shell and open your terminal. Then run this command

sudo apt-get autoremove mint-meta-mate

It will uninstall every thing related to linux mint. But still linux mint already changed many things in software repo. So you have to move back to old repo (ubuntu 11.10). For that run these commands

1. Remove linuxmint repo link from software list.

sudo gedit /etc/apt/sources.list

1. Remove the old software list. Then move the software list to new directory and create a software list directory. For that follow the below commands.

cd /var/lib/apt
sudo mv lists lists.mate
sudo mkdir -p lists/partial

1. Getting the ubuntu 11.10 repo

sudo apt-get update
sudo apt-get check
sudo apt-get clean
sudo apt-get autoclean
sudo apt-get autoremove

After that also the ubuntu software center is not working 😞 . The problem is "no module named linuxmint". The reason for this error is every where the distribution id is linuxmint.

lsb_release -a

it prints

Distributor ID: LinuxMint
Description: Linux Mint 12 Fluxbox
Release: 12
Codename: lisa

1. Remove linuxmint distribution id from everywhere

sudo gedit /etc/*release

and change everything in the file to:

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=11.10
DISTRIB_CODENAME=oneiric
DISTRIB_DESCRIPTION="Ubuntu oneiric"

Then run

sudo gedit /etc/*issue

and change to:

Ubuntu 11.10 \n \l

1. Restart your machine. Then restart your machine. Now in the login screen you don't see the mate shell option.

Cheers.…!!! 😃 😃 you are done...

Taken from android browser

Two weeks before irctc launched mobile site for train booking. But when I try to go https://www.irctc.co.in/mobile from my pc its redirect to usual site. The problem is they are checking the request coming from mobile or computer in server side using user agent and if its from mobile allowed otherwise its redirected to ordinary site.

So here is the fix 😄

Requirement:

• absolutely a pc
• Mozilla Firefox
• User Agent switcher add-on

How to:

• Open Firefox
• Download and Install the User Agent switcher add-on from here 
• Change the User agent to iPhone 3.0 by Go to Tools
• Now open the https://www.irctc.co.in/mobile in Firefox
• Yeah you are done. cheers...!!!

User Agent switcher:

Change to iPhone 3.0

How irctc looks in firefox:

Mobile Login page

Mobile Home page

Mobile plan my travel

Advantages of mobile agent:

• Firstly its very fast.
• Easy to book. Just three clicks.
• No more asking password again and again
• No more session expired / timeout page :D
• Do remember you can only book 5 transactions per month through mobile irctc site.

FAQ:

I tried in mobile still redirect to ordinary site..?

Use https instead of http and make sure www in that url https://www.irctc.co.in/mobile

How can I change the user agent in google chrome..?

To change user agent in google chrome check this video tutorial http://www.youtube.com/watch?v=IiT7z8zAbn0 But for that you need chrome 17 version. To find out which chrome you are using type "" in address bar then enter. If you have chrome version 16, wait for 17 to be stable otherwise try beta version.

Update: Now a extension is available for chrome https://chrome.google.com/webstore/detail/djflhoibgkdhkhhcedjiklpkjnoahfmg use this.

Is this irctc hack..?

No. Its just a browser hack..!!! you can see any mobile website using this.

How to use this mobile site..?

Please find the manual from here. View Manual

Its shows me a blank page..?

Last few days I am also getting blank pages. That website is seems to be down. Even its shows error page when I tried from mobile device. No fix for this 😄 check this link for its down or not

My Firefox is does not support for this add-on..?

I think you are using old one. Try to update your firefox browser. OR from here http://releases.mozilla.org/pub/mozilla.org/addons/59/ you can find the different version of that add-on. Download which one is suitable for your firefox.

Here we are going to learn how to copy commits from your master to branch.

Basically I am a linux enthusiast so I will explain everthing here in commends. Feel free to use git commends 😄

• First you have to check where you are now.

git branch -a

That * will where you are. Now I am in Master branch.

GIT Branch

• Create a new branch and move to that created branch

git branch 
git checkout 

If you are already created branch. No need create branch just git checkout

• Once again confirm Are you in correct branch.

git branch -a

• Pick up the commits to this branch

git cherry-pick 
Ex: git cherry-pick d1c4b9a5a21e3d09cae

• How to get the hash tag of commits

git log

GIT Log

You can get the has tag from here.

• Then Switch back to master

git checkout master

• For push this branch to remote server

git push origin 

• For delete the locally created branch

git branch -D 

public static Date getLastDateOfMonth(int year, int month) {
  Calendar calendar = new GregorianCalendar(year, month,
  Calendar.DAY_OF_MONTH);
  calendar.set(Calendar.DAY_OF_MONTH,
  calendar.getActualMaximum(Calendar.DAY_OF_MONTH));
  return calendar.getTime();
}

1. In the first line we are creating calendar object with year, month and day. In these parameters we can pass any int to that day, I passed 5 here.
2. calendar.getActualMaximum(Calendar.DAY_OF_MONTH) its returns the maximum day of this month. For example it will return 31 for January.
3. calendar.set() set that maimum day to that current month day. Finally you got the last date of the month.

Such as you can get the first date of this month using getActualMinimum() fucntion. Anyway all month starts with 01 :)

Simple enum for month

enum Month {
  JANUARY, FEBRUARY, MARCH, APRIL, MAY, JUNE, JULY, AUGUST, SEPTEMBER, OCTOBER, NOVEMBER, DECEMBER;

  public String getDisplayName() {
    char[] charArray = name().toLowerCase().toCharArray();
    charArray[0] = Character.toUpperCase(charArray[0]);
    return new String(charArray);
  }

  public int getId() {
    return ordinal();
  }

  public String getValue() {
    return String.format("%02d", getId()+1);
  }
}

Sometimes you want to display month select box in jsp. At that time you can use getDisplayName() and getValue() functions with in enum.

 id="monthBox" name="monthBox" >
 var="month" items="${monthList}" >
 value="${month.value}" />">
  value="${month.displayName}" />

Here the above code is in struts MVC. The monthList value is set from ModelMap.

The console outputs for that java class

For example Initially this blog http://bit.ly/ndtgfq shown below

Tamil font is not rendered properly

But in the firefox its rendered correctly. It shows the fonts correctly. I solved this issue after little bit googling 😜

Here is the fix.

• Goto that directory /usr/share/fonts/truetype/freefont/
• Delete both the FreeSerif.ttf and FreeSans.ttf file.

sudo rm -f /usr/share/fonts/truetype/freefont/FreeSerif.ttf 
sudo rm -f /usr/share/fonts/truetype/freefont/FreeSans.ttf 

Then restart your browser. Now its shown correctly for me.

Tamil font displayed fine

Yes you are correct. But this is a partial solution. When you add / create new files with in that folder it have the old permissions. To solve this issue, create / add file with particular permission in that folder. Here is it how to do that.

First you have create new group. This is an optional one, you can use anyone of your old group. For me I created a new group called "media". Assign this group to user whom want you share.

sudo groupadd media
sudo usermod -a -G media friends
groups friends

In second command option "-a" is important. Then only this group is append to the existing group list otherwise all sub-groups are removed. The final command will display the user is belong to which are the groups. You can also do this using GUI. Goto System → Administration → Users and Groups

Add new group and assigned to users

Change group to "media" for existing files and folder with in which directory you want to share.

sudo chgrp -R media Music/
sudo chmod g+s -R Music/
sudo chmod 755 -R Music/

In command "-R" for recursive operations. It will change all folders and subfolders files. Second command for set group id for Music and sub directory. Final command for RWX access for user and RX access for group, others for existing files.

Now when you create a new directory with in Music. The "media" group is assigned to that folder. it will look like

arul@arul-laptop:~/Music$ mkdir sample
arul@arul-laptop:~/Music$ ll
drwxr-sr-x 2 arul media 4096 2011-08-19 00:06 sample

Music folder list view

Now login as other user. create symbolic link for media folder for easy access.

friends@arul-laptop:~/Music$ ln -s /home/arul/Music ./"music on arul"

To know more about File permission view this ubuntu help page.

command creation

First you have to find the location for "fromdos". Below command will return the location

which fromdos

Then you have to create a soft/symbolic link for that location with the name "dos2unix"

sudo ln -s /usr/bin/fromdos /usr/bin/dos2unix

Follow the same steps for unix2dos.

• Try to get your firmware from internet. Or use this I5503DDJG4 , I5503DXJG5 2.1 firmware (Galaxy 5). Password for zip file is “samfirmware.com”
• Use the same ODIN and OPS file and follow the same steps above.

The problems in my mobile only. It may vary for your mobile. Some problems are resolved and some could not.

My Specification:

Model - Samsung GT-I5503 a.k.a Samsung Galaxy 5
Version - Android 2.1 Eclair
Firmware - 2.1-Update1

Can not delete multiple contacts:

There is no option to delete more than one contacts. If you want to delete 10 contacts you should go with one by one.

Doesn't sync with google contacts groups:

I have contact groups in gmail contacts, but its not synced with my mobile contacts. Now all gmail contacts in one group.

Contact image not shown when dialing:

The contact image is not shown when I calling to someone. The image came once they attend the call. But not a problem in incoming call, always image came.

The most of the contacts related problems seems to be solved in Froyo. I need to update my OS version. But samsung does not provide update for Galaxy 5 😔

Can not connect with ad-hoc network:

This is the most known android issue. If you use wifi analyzer it will detect the ad-hoc network. but in the Settings → Wireless and Networks not even detect the network.

Could not detect your location:

I solved this problem. When i try to to find "My Location" in Latitude. It always says "Your current location is temporarily unavailable."

Goto Settings → Location and Security → Check both Use wireless networks and Use GPS satellites. Thats it

Sometimes showing wrong time:

Sometimes my mobile shows correct time and sometimes it shows current time + 5:30 hours. Finally i solved this. The issue because of getting the time from GSM network.

Goto Settings → Date and Time → uncheck the Automatic

Proxy only for browser not for applications:

Actually I set proxy for wifi network, But the proxy is works only for browser not for application you installed.

To Set proxy Goto Settings → Wireless and networks → WiFi Settings → Advanced

Sync Issue:

If any issue came in syncing. That application is not working any more. I had a problem in syncing in calendar. After that calendar application is not opening. Its works after successfully synced. For sync Goto Setting → Accounts and Sync

Bluetooth headset is not supported:

There is no option to connect my bluetooth headset. Even my LG KG195 supports bluetooth headset. 😜

Auto Reboot:

This is a big headache. it will automatically reboot if more process run at a same time :oops:

Finally I came to a conclusion I need to update my OS version and samsung firmware. It will solve most of my problem.  Anyone successfully update OS / firmware for Galaxy 5..?

Last 6 months this post draft today only got the time to finish and post. 😄

To prevent copy and email address from a text box. This is used in most of the sign-up form.

Requirment:

• Jquery 1.6
• Jquery Validates plugin (optional)

Here I have used jquery validate plugin for validating email in the form.

How to prevent copy and paste in a text input..?

$("#user.email").bind("cut copy paste", function(e) {
    e.preventDefault();
});

e.preventDefault() — means its return false.

if you want to toggle use return statement.

return true — means you are allowed to copy and paste content in the text input

return false — means its prevent copy and paste in the text input.

Demo Form:

For Toggling copy email depends upon the check box status the following javascript is used in the above demo

$("#user.email").bind("cut copy paste", function(e) {
    //e.preventDefault();
    return $("div input[name='allow.copy']:checkbox").is(":checked");
    // false means not allow to copy.
});

         width="{sl.value}" height="0" />
    
    
         id="button2" label="You" />
    

Running example:

• Goto installed plugins about:plugins in chrome / mozilla
• Click Details to view with more information. Disable the Flash Plugin. The Location of the plugin would be "/usr/lib/adobe-flashplugin/libflashplayer.so"
• Download the tar.gz version of flash player from here http://get.adobe.com/flashplayer/
• Extract that file and copy the libflashplayer.so to /usr/lib/chromium-browser/plugins .  Then Enable this in plugin page.
• If you view any video it will download in /home/\/.cache/chromium/Default/Cache this folder.
• For Google chrome user cache location will be /home/\/.cache/google-chrome/Default/Cache

Make a link for easy access

ln -s /home/arul/.cache/chromium/Default/Cache/ /tmp/chrome-cache

My Configuration:

• OS : Ubuntu 10.04
• Browser : Chromium 10.0.648.133 (Developer Build 77742) Ubuntu 10.04
• Flash : Shockwave Flash 10.2 r152

Update on 21th March 2011:

After a deep testing the video downloaded is disappear after sometime. I tested against youtube.

Otherwise use older version:

Download the older version of Flashplayer 10. Then copy that to chromium plugin directory. Enable this plugin now you can get the file in the /tmp directory. I am using Version: 10.0 r45. I get this version from with flex sdk runtime folder.

rb.mousePress(InputEvent.BUTTON1_MASK);
rb.mouseRelease(InputEvent.BUTTON1_MASK);

Using this i can made upto 15,000 clicks. I am using openjdk in ubuntu. I could not break my friend (Ponraj) record. May be bad thread handing mechanism in openjvm.. Or OS dependency i am not go deep with in that... He using some better code than me. I think he used Selenium with this. Need to discuss with him and will update here... And i forget to mention your browser also have some limitation... 😌

Here is the code I used...

import java.awt.AWTException;
import java.awt.Robot;
import java.awt.event.InputEvent;

public class FBClick implements Runnable {

 private static Boolean timeout = false;

 @SuppressWarnings("deprecation")
 public static void main(String d[]) throws InterruptedException,
 AWTException {
   Runnable fb = new FBClick();
   Thread th[] = new Thread[2];
   Thread.sleep(6000);
   for (int i = 0; i < th.length; i++) {
     th[i] = new Thread(fb);
     th[i].start();
   }

   Long startTime = System.currentTimeMillis();
   while (true) {
     Long endTime = System.currentTimeMillis();
     if (endTime - startTime > 11000) {
       for (int i = 0; i < th.length; i++) {
         th[i].stop();
       }
       timeout = true;
       break;
     }
     Thread.sleep(3000);
   }
   System.out.println("The end");
 }

 @Override
 public void run() {
   try {
     Robot rb = new Robot();
     while (!timeout) {
       rb.mousePress(InputEvent.BUTTON1_MASK);
       rb.mouseRelease(InputEvent.BUTTON1_MASK);
     }
   } catch (AWTException e) {
     e.printStackTrace();
   }
 }
}

How to use this code..?

Compile and Run this java Code and place your mouse on START Button...

Think like a programmer.. i copied this quote from him... 😄

There are different ways to get the version of ubuntu you are using... Here we are going to discuss the all ways...

This option is common to all linux flavors . it will display the kernal and other information too.

uname -a

cat /etc/issue

lsb_release -a

Press CTRL+ALT+F1

Then switch back to X11 using CTRL+ALT+F7

Goto System → About Ubuntu

How to type tamil in ubuntu ..?

Goto System → Preferences → Keyboard .

Then choose the Layouts tab. Click the "Add" button. Then Change the country to India and choose your tamil layouts. For myself i choose "India Tamil Unicode"

Now you can see your layouts in the window.

You can change your typing language using the keyboard layout on the top panel. By clicking on this applet you can change the language layout what ever you want.

Now i can type in tamil any where in ubuntu.

நன்றி ... அருள்.. :)

Here I will explain how to resolve hectic problems in ubuntu (that I felt were tough). Here is the list of my problems.

1. Number Lock not enabled when booting
2. Brightness adjustment
3. Tata photon+ data card problem
4. Unauthorized resource when update
5. VLC problem
6. GPG error: http://ppa.launchpad.net lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY D225991A72B194E5Failed
7. Screen lock for root user
8. "P"- Button in Acer 5740

Enable Numlock when boot..?

By default the Number lock is disabled. To enable Numlock when booting.

• Install numlockx from your ubuntu software center
• add the line shown below, at the End of File (before exit0)

| if [ -x /usr/bin/numlockx ]; then |  /usr/bin/numlockx on |  fi

OR

You can add numlockx in startup ( System → Preferences → Startup Applications).

But in this solution the num lock will turn on only after logged in.

| Brightness Adjustment ..? |  In ubuntu there is a option to adjust the brightness. But no luck for me

Go to → Preferences → There is a option available for brightness adjustment.

Tata Photon problem ..?

Tata Photon plus came with my laptop as a vendor compliment. When I plugged the data card in my system, it was not detected, it was just detected as memory card (as pen drive ). Here are the steps to fix for this issue.

• Download usbmodeswith from this link or you can download from ubuntu software center.
• Run this "lsusb" and find Product and Vendor id respective to the "Huawei Technologies Co., Ltd." for mine its like 12d1:1446 in that vendor id is 12d1 and product id is 1446
• Goto this folder /etc/usb.modswitch.d/ then find the file with name "12d1:1446"
• Add this 140b in TargetProductList in that file
• Now run this command. " usb_modeswitch -v VENDOR_ID -p PRODUCT_ID -M MESSAGE_CONTENT ". For mine " usb_modeswitch -v 12d1 -p 1446 -M 55534243123456780000000000000011060000000000000000000000000000 "
• Now the data card detected as modem.
• To Check whether its detected as a modem run the lsusb command its changed to 12d1:140b

Ubuntu Software Center:

lsusb:

cat 12d1:1446:

usb_modeswitch command:

To check:

The disadvantage is that,  you need to run this command every time you plug in the card. Guys if you know a better solution comment here.

Unauthorized resource when update ...?

This error came when i was update my system using "Update Manager" (System → Administration → Update Manager). Here are the steps to resolve this issue

• Goto System → Administration → Software Sources
• Change that Download From Select Box to Main Server instead of Local Server (For mine Server From India)

gpg --keyserver keyserver.ubuntu.com --recv 72B194E5

gpg --export --armor 72B194E5 | sudo apt-key add -

| Use these last 8 digits for any other keys . I referred from here |  Screen lock for root user ..?

From my understanding from various forums, the screen lock for root user is disabled in the linux kernal itself. But I found a message in the screen saver itself. Here it is

OS - Ubuntu 10.04

Login user - root

Machine - Acer 5740

When i am work with a Difficult Flex application its hard to find which log is come first and which one come second in the flashlog trace. I searching for any log4j api like in flex. Yes i got.. Flex have that inbuit. Here i share that how to i use in my project... The Class is "**TraceTarget**"... Using that class you can trace your log in different way like Debug, Info, Warn and Error.. Here is My example

sharedaaExample.mxml

 xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:sharedaa="com.sharedaa.\*" creationComplete="creationComplete()" preinitialize="initLogging()">
  
  
   import mx.logging.Log;
   import mx.logging.ILogger;
   import mx.logging.LogEventLevel;
   import mx.logging.targets.TraceTarget;
   import flash.ui.ContextMenu;
   import flash.ui.ContextMenuItem;
   import flash.net.navigateToURL;
   import flash.net.URLRequest;

   import flash.events.ContextMenuEvent;

   import flash.display.StageDisplayState;

   private var chatContextMenu: ContextMenu;

   private function initLogging(): void {
     // Create a target.
     var logTarget: TraceTarget = new TraceTarget();

     // Log only messages for the following packages
     logTarget.filters = ["com.sharedaa.\*"];

     // Log all log levels.
     logTarget.level = LogEventLevel.ALL;

     // Add date, time, category, and log level to the output.
     logTarget.includeDate = true;
     logTarget.includeTime = true;
     logTarget.includeCategory = true;
     logTarget.includeLevel = true;

     // Begin logging.
     Log.addTarget(logTarget);
   }

   private function addContextMenu(): void {
     chatContextMenu = new ContextMenu();
     chatContextMenu.hideBuiltInItems();
     var item: ContextMenuItem = new ContextMenuItem("www.arulraj.net");
     item.addEventListener("menuItemSelect", openNewWindow);
     chatContextMenu.customItems.push(item);
     this.contextMenu = chatContextMenu;
   }

   private function openNewWindow(event: ContextMenuEvent): void {
     navigateToURL(new URLRequest("http://www.arulraj.net"), "\_blank");
   }

   private function creationComplete(): void {
     addContextMenu();
     main.initMain();
     main.printLog();
   }
   ]]]]>
  
   id="sharedaa">
     id="mainCanvas" x="0" y="0">
       x="0" y="0" id="main" />
       text="Example for Trace with Time" />
    
  

And the Actionscript file is

Main.as

package com.sharedaa {

  import mx.containers.VBox;
  import mx.logging.Log;
  import mx.logging.ILogger;

  public class Main extends VBox {

    private static var LOG: ILogger = Log.getLogger('com.sharedaa.Main');

    public function initMain(): void {
      LOG.debug("intialize main");
    }

    public function printLog(): void {
      LOG.info("This is a info log");
      LOG.debug("here is a debug log");
      LOG.warn("display your warnings here");
      LOG.error("This is a error");
    }
  }
}

After a long time i am working on Flex for one of client for his one to one chat application. At this time i need flash debugger for debugging my program. The debug player need for to print trace() output to flashlog.txt.

Here the steps for how to install debug flashplayer in ubuntu 10.04 firefox 3.6.

Steps:

• Download the debugger version from here . Or Download this Zip file for Linux http://download.macromedia.com/pub/flashplayer/updaters/10/flashplayer_10_plugin_debug.tar.gz
• Extract that zip file and get that "libflashplayer.so"
• Goto this folder "/usr/lib/mozilla/plugins" then copy and  paste that libflashplayer.so here. Then Delete the shortcut named "flashplugin-alternative.so"
• Create a mm.cfg file in your home directory. For example /home/\/mm.cfg
• The mm.cfg file is look like the below

ErrorReportingEnable=0
TraceOutputFileEnable=1
MaxWarnings=0

Then restart your firefox now you can found flashlog.txt file in

cd \$HOME/.macromedia/Flash_Player/Logs/ folder.

Update on 19th October 2011:

• Download the debugger version from here. Then extract that libflashplayer.so
• Copy that so file to /usr/lib/mozilla/plugins/ dir
• Then replace the soft link by the following command

sudo ln -fs /usr/lib/mozilla/plugins/libflashplayer.so /usr/lib/mozilla/plugins/flashplugin-alternative.so

Its works with my Firefox 7.0.1 in ubuntu 11.04

Google Translator can convert any word/sentence from one language to other language. Now a days all web application have i18n support. The developers just create a properties file for English in key value format and then using google translator they create other language properties for his/her testing purpose.  But in this method they need to go google translator webpage and convert line by line to make the other language properties file. But this process takes more time than writing a code :) [really...!]. I too pass this situation, at that time i just search google is there any Java api for google translator.

Then i found a opensource software for this, that is called Google api translate . Now come to the topic, here a java class for converting your English properties file to Chinese .
