Make your Prompt Pretty and Powerful

2013-02-17T03:38:00.002-08:00

I've received a lot of request on what I did to my shell, how to get it to look and behave the way it does, so I'm writing a guide on how to do it.

Requirements

Zsh with Oh-my-zsh config
Powerline Theme
Patched Fonts
GNU Screen (Optional but recommended)

Overview

I'll be writing the step by step guide to getting all of this working. Zsh is required, and most of you probably use bash, but this is not a problem. You can still use bash on your system. You're not replacing bash, just adding zsh. Zsh is mostly reverse compatible with bash (meaning whatever you do in bash will work and work the same in zsh for the most part), but after learning all of what zsh has to offer, you probably will find yourself rarely using bash.

Zsh without a good config is pretty useless. You can go through the kind of long process of creating a zsh config, but I highly recommend using "Oh My Zsh" and then add further customizations to it if you want to. I will give some of my extra configurations I used for it, and you can use them if you'd like.

The patched fonts are supposed to be needed for the theme to display correctly. However, on my machine, I am using Ubuntu Mono Font not patched and only noticed one small glitch that only appears when my pwd is under a git repository directory. You can use Ubuntu Font ( http://font.ubuntu.com ) under any distro or even an entirely different OS. Mono, fixed width fonts are recommended.

GNU Screen adds to shell by making it much more powerful, and also nicer looking with the status and caption bar that you can customize to show different things such as system load all using colors you choose for it. It makes working at the shell much more powerful by giving the ability to have multiple shells running in different "screen windows" (not sure what else to call them), horizontal splits (like the one shown in the screenshot, detaching from a screen, so you can at a later time or date, re-attach the same screen and continue where you left off, monitor for activity or no activity, and have a shared terminal between a friend, coworker or somebody needing help, where both of you can see and type in the same terminal where one user connects through ssh and attaches to your screen session. I won't go into detail on how to do all of that, but I will provide a few links where you can read on how to do all of that.

Guide

First, you need zsh. So use your distros package managers, yum install zsh, apt-get install zsh, emerge -av app-shells/zsh, ~~pacman -S zsh~~, sbopkg.

Next, zsh is not so good without a good config for it. You need Oh-my-zsh config because of the theme support.

https://github.com/robbyrussell/oh-my-zsh

You can either use the authors install script

wget --no-check-certificate https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | sh

Or follow the instructions for manually installing oh-my-zsh from the above website.

Once you've done that, you'll need to either logout and log back in for your Linux user or type zsh at the command line to begin using zsh.

Now, to get the prompt that so many have been asking me about, you need the Powerline theme for oh-my-zsh.
If you don't have the git command, use your package manager to install git. This can be done with commands such as apt-get install git or yum install git depending on which Linux distro you use.

Here's the commands you'll need to do in order to get this powerline prompt installed and working.

git clone git://github.com/jeremyFreeAgent/oh-my-zsh-powerline-theme.git
# This next command I do makes the directory a hidden directory.
# I do this to keep my home directory uncluttered.
mv oh-my-zsh-powerline-theme ~/.oh-my-zsh-powerline-theme
cd ~/.oh-my-zsh-powerline-theme
./install_in_omz.sh
# Use gedit, vim, or whatever text editor you want except emacs. To keep it simple,
# I am using nano here.
nano ~/.zshrc
# Now find this line -> ZSH_THEME="robbyrussell"
# And change it to this -> ZSH_THEME="powerline"
# Save and exit from the editor.
source ~/.zshrc

Now your prompt should look similar to mine in the screenshot. Install fonts patched for powerline.

git clone https://github.com/pdf/ubuntu-mono-powerline-ttf.git ~/.fonts/ubuntu-mono-powerline-ttf
fc-cache -fv

Then set your terminal program to use Ubuntu Mono. If you'd like a different font, just search github for the fonts name powerline. I didn't have to use a patched font for the prompt to display correctly.

See info below for how to update the theme any time you want to update to the latest version.

Terminal Colors

To get the colors the same as I have, open gnome-terminal (or other terminal you use), choose XTerm under "Color Pallet:". Set the text color to be white, bold to be same as text color, and the background to be a grey color with the RGB color code to #3F3F3F

Updating Oh-my-zsh Config and Powerline Theme

Go into the directory containing the powerline theme. If you used the same directory I used in this guide, then:

cd ~/.oh-my-zsh-powerline-theme
git pull
cd ~/.oh-my-zsh
git pull
source ~/.zshrc

Although, by default, the oh-my-zsh configuration will automatically update twice a week.

Tips for Zsh

There are several plugins you can use with oh-my-zsh.

ls .oh-my-zsh/plugins

That gives you a list of available plugins you can use. These plugins are managed in your .zshrc file. For example, if you wanted to use the colemak and github plugins, you would change this line:

plugins=(git)

To this:

plugins=(git colemak github)

Zsh has excellent tab completion. For more information on Zsh, see my other blog post. It has a youtube video as well.
http://linuxinnovations.blogspot.com/2010/10/ultimate-tab-completion.html

Here are the customizations I added to my bottom of my .zshrc. Use them if you'd like:

########################################
# Customize to your needs...
export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/bullshark/bin

# Allow comments when using zsh interactively
setopt interactivecomments

# Turn off annoying autocorrect for dot files

# Print the first line, column names, of ps output
# Search and output the argument
function psgrep {
  if [[ $# -eq 1 && $1 != '-h' && $1 != '--help' ]]
  then
    ps aux | head -n 1
    ps aux | grep -E "$1"
  elif [[ $# -eq 2 ]]
  then
    ps aux | head -n 1
    ps aux | grep "$1" "$2"
  else
    echo "Usage: $0 [GREP_OPTIONS] regexp"
  fi
}

# List installed packages in descending order
alias pkglog="grep ' \ install\ ' /var/log/dpkg.log"

Welcome to Gentoo

2012-07-06T22:20:00.000-07:00

To get this with your Gentoo install, simply do

cp /etc/issue.logo /etc/motd

Edit /etc/motd with your favorite text editor, vim, nano, gedit, and change the last line. The escape sequences won't show up. If you set this up as your /etc/motd, it should show up anytime you login, whether a virtual console or ssh. If you set it in /etc/ssh/sshd_config with "Banner /etc/issue.logo", it will only show up in ssh before the password prompt appears. I tried that, and the colors did not show. My suggestion, set it as your /etc/motd and edit the last line.

JSpeak - The Ultimate in Linux Text-to-Speech Software

2012-05-09T16:02:00.001-07:00

JSpeak is a FOSS (Free Open Source) Application I created for Linux, the only of it's kind.

It's full of features. It's primary feature is it's ability to read text copied to the clipboard. It also can use Mbrola voices. It expands and retracts to a smaller graphical user interface that is perfect for hovering over your ebooks, websites, etc. while reading from them. It's located on Github at
https://github.com/BullShark/JSpeak under the GPLv3 and above, free of charge.
The full instructions on getting it running and how to use it are there on that github link. There is also a wiki there on Github.

Please check it out. I would really appreciate it as well as any feedback and/or support through donations. If you like this software, please make a donation to help further development here on my blog. Thank you.

Octal Permissions Pro Tip

2011-12-20T11:29:00.000-08:00

Introduction

For Linux and Linux like OS, file permissions can be set with octal (0-7) using chmod and umask. umask works differently than chmod by setting default permissions of newly created files and directories by subtracting permissions. I won't go into detail about this now. This page assumes you know the basics of those file permissions. You may have seen chmod 755 or similiar many times. How can we know what each number means? Memorize? Maybe, but there's a better way.

Easy Method

You only need to remember this:

4 = read 2 = write 1 = execute

Notice I did not include 0; because that is easy to remember that it means no permissions. Now all you need is simple addition to figure out a combination of permissions. For example, the 5's in 755 means

4 (read) + 1 (execute) = 5 (read and execute)

Now if you want for example read and write permissions only, just follow the simple addition again.

4 + 2 = 6

To verify this is true, I will show you the results on my machine.

[bull@beastlinux bin]$ chmod 600 vpaste

[bull@beastlinux bin]$ ls -l vpaste

-rw-------. 1 bull bull 355 Dec 19 03:54 vpaste


[bull@beastlinux bin]$

Another note:

To help remember, 4, 2, 1 which is which. They go in the same order as shown -rwx------. The order is read (4), write (2), execute (1).

Conclusion

Happy chmodding =)

HackWarez Caught Being Shady

2011-04-27T18:29:00.000-07:00

Over at the Hackwarez community, some shady things were taking place and now leaked. The appearance of the golden ratio again 1337.

I have got to know this community of of the hackerwarez (they like to go under the alias of slackware). Always approach with caution. If you site one, you are advised to do the following steps.

Run emergency synchronisation of source to backup location. Sync all buffers, remount everything as Read-Only.
Find a bomb shelter. These can be found often in disguise because they are now being used as everyday facilities, schools, etc., that had been built long ago during war times. Do not expect that you will be able to transmit or receive any RF Signals from you Linux Handheld mobile unless equipped with aircrack-ng and a double bi-quad extremely high-gain amplifier.
This belongs as 1. IMMEDIATELY take any computers running windoze and microslaft products off the network by yanking the cords from routers, switches, steal rolling windows mobile phones, flashing the firmware. At all cost and for the safety of all people, do this one with most importance.

Blackhats Re-Vamped the Linux Desktop

2011-04-23T23:10:00.000-07:00

Click below to see the img in full view. I recently gave Gnome3 a test run, and couldn't decide if I liked it or not. There are certainly things I both like and dislike about it, so I will check back on it when another major revision is done. It made me think of a mix between KDE and Ubuntu's Unity, so in case I was not happy with their final product, I had to find an escape. I played around with awesome tiling manager, xmonad (I didn't want to learn Haskell just to write a config file for it...but it's very good), and enlightenment v17 aka e17. I seddled with XFCE, not because it's the most light weight (it isn't really), but because I have a sexy Linux desktop that keeps me informed, and it's written with GTK+ (so it plays nicer with gtk apps).

In the image below, you can see I am using WeeChat+Tor helping one of the regular visitors to our IRC channel. He's also been very helpful, a good Linux using community is here. You can find me here, but I may not always be at my computer.

Now notice that the icon for wifi (wicd-gtk) wasn't displaying at it's best. Since I have themed my XFCE4 to look like KDE and wanted BIG icons, I took some icons from KDE's Oxygen theme and replaced all the ones wicd-gtk was using with it. See below for the difference. So if you'd like to use it them, I have tar'd them up and linked below. Just overwrite all existing icons in /usr/share/piximaps/wicd (path on most systems) with the ones provided.

http://tcnoe.net/files/wicd-oxygen-theme.tar.bz2

Since our channel, ##blackhats on FreeNope, is having a Bot Coding competition, I included this image =) We have many participating from low range of skills to a higher range of skills. If you're interested in participating, just join the channel, introduce yourself and let us know.

For the Linux community

2010-11-18T22:53:00.000-08:00

Listen to the good sounds of that one. I'll write up a guide on RAID in Linux when I'm less busy with school, and then put a disk in failure by ripping it out of my computer like I had in the past. Linux handled it well, not even a pause or slow down. I put it back in and rebuilt the array all without powering down my machine.

Peace bitches!

GNU Screen With Byobu

2010-11-12T15:14:00.000-08:00

Byobu is manager for GNU Screen hidden within Ubuntu 10.10 Maverick. It's also available through the Debian repos. If you are running Ubuntu 10.10, I'll show you how to unhide it and use it. First right click "Applications" and click "Edit Menus" as shown in the picture.

With "Accessories" selected in the left pane, you will see "Byobu Window Manager" in the left pane. You need to tick (check it) to have it appear in your menu.

Now it should appear in your menu like the picture below.

To make the Terminal better for using it, I suggest creating a new profile based on the default profile and changing it up a bit.

Also I set this new terminal profile to be the one used when launching a new terminal.

Because using Screen with Byobu will display a lot of information that you configure it for at the bottom of the terminal, I suggest changing the default width of the terminal. I changed mine to 132 pixels.

Here you can optionally set a semi-transparent/translucent background.

If you followed my previous guide to using Zsh and screen with a .screenrc configuration file, your terminal should appear like this. I did have to make 2 changes to my .screenrc file. I commented out the hardstatus lines because Byobu configures that and that can be further configured through a menu system in ncurses by hitting F9.

I have Byobu configure to show my system uptime, cpu temp, disk and network I/O, IP as well as some other information. To get some default screens you can switch between, you can set this in ~/.screenrc. Here is mine.

#hardstatus alwayslastline
#hardstatus string '%{= kG}[ %{G}%H %{g}][%= %{=kw}%?%-Lw%?%{r}(%{W}%n*%f%t%?(%u)%?%{r})%{w}%?%+Lw%?%?%= %{g}][%{B}%Y-%m-%d %{W}%c %{g}]'

# Default screens

chdir ~/
screen -t bash    0 /bin/bash
chdir ~/Coding/CS2213
screen -t zsh    1 # will run zsh by default
chdir ~/Hax0r
screen -t zsh     2
chdir ~/
screen -t zsh     3
chdir ~/
screen -t zsh     4

If you do not have Zsh installed, here is one you can use with bash being your only shell. Only uncomment the hardstatus lines when using GNU Screen without Byobu.

#hardstatus alwayslastline
#hardstatus string '%{= kG}[ %{G}%H %{g}][%= %{=kw}%?%-Lw%?%{r}(%{W}%n*%f%t%?(%u)%?%{r})%{w}%?%+Lw%?%?%= %{g}][%{B}%Y-%m-%d %{W}%c %{g}]'

# Default screens

screen -t bash1    0 
screen -t bash2    1
screen -t bash3    2
screen -t bash4    3
screen -t bash5    4

To switch between these screen windows in the terminal, there are some commands/key bindings you can use. All of them begin with hitting Control and a followed by another key. I'll give you a few. You can always type Control a then ? for a list of all of them if you forget. Where ever you see "^", that is referring to the Control key. They assume you know to push Control and a (^a) first before using these keybindings. Here are a few commonly used ones.

^a n (Means go to the Next screen window)
^a p (Means go to the Previous screen window)
^a c (Means Create a new screen window)
^a " (Will give you a full list of screen windows to choose from)
^a [ (Will allow you to use the arrow keys to scroll and also if you want, highlight a selection to copy)
^a ] (Will paste whatever you copied to the buffer with the previous command)

Now that you have Screen/Byobu running, open a new terminal window.

Type into the terminal

screen -ls

You should see one screen session running. If that is your only screen session running, then type this next one.

screen -x

That will connect you to that running screen session, so now you see the exact same thing in both terminal windows. Try typing something and see if it appears in both terminals in real time as it's typed. I'll show you how this is useful.

You can leave the screen session running and disconnect from it with "^a d" and then later connect to it again with the screen -x command. This is very useful if you are helping a friend. You can ssh into the friends computer and both be connected to the same screen session, so that you each see the same thing and are both able to type. That requires you to both be logged in as the same user unless you have set the suid bit on the screen excutable and allowed multiuser in the to the screen session, but I will not go into that now for this guide.

You may be bored with that stupid default prompt you get by your distro. Optionally you can change it to what you like. If you are using bash, you can change it by adding the following to the bottom of your ~/.bashrc

export LIGHTCYAN='\e[1;36m'
export LIGHTRED='\e[1;31m'
PS1="\[$LIGHTCYAN\]$(lsb_release -s -c)\[$LIGHTRED\] >> \[$LIGHTCYAN\]"

After doing that, you will need to have the .bashrc re-read. You can do this by opening a new terminal window or typing this command.

source ~/.bashrc

My Grandmother Uses 4096 Bits Of Encryption

2010-11-11T14:59:00.000-08:00

Introduction to GNU Privacy Guard

Almost every flavor/distro of Linux comes with a certain set of tools, one of them is a powerful tool for encryption called the GNU Privacy Guard or GPG. GPG can encrypt files, text, emails. Each user using GPG has both a private key and a public key, key-pair. The public key is meant to be shared to friends and everyone. One way this is done is by putting it on one of the key servers, so people searching for your key can find it and import it into his or her keyring. Once someone has your key, that allows them to encrypt data to you as a recipient, so that you can decrypt it. You may be the only recipient of some encrypted data. In that case, not even the person who encrypted the data to you can decrypt it! GPG also has the ability to generate a signature that nobody else could generate without your private key and password (I hope you give it a long random secure password). If you have signed the key because you trust the key was really created by the person who it's supposed to belong to, then it's a safe bet that when you see a GPG signature such as in an email, the email was really sent and written by that person, not a spoofed email.

To begin, invoke " gpg --gen-key " at the command line. I'm going to create an example key and highlight the input I suggest you use or replace with your own information.

Note, that once you get to the part generating entropy, gpg is gathering random information to use in generating your key, so you will need to do some tasks that involve heavy disk usage, number crunching, etc. One nice way to do this is to hit alt f2 and run baobab. Tell it to scan the entire filesystem. To check the progress of entropy being generated, open another terminal window and type cat /dev/random. The more random bits of information that you see appearing is what you want and is what gpg is waiting for.

Now you should be able to see your key with the following command. My example shows other keys I have imported into my keyring as well as my own and newly generated one I used as an example for this guide.

Now you'll want to put that key up on keyservers, so others may find and import your public key.

To do this, use the Key ID (for my example, it is the last thing I marked in red) for the following command.

➜ ~ gpg --keyserver hkp://keys.gnupg.net --send-keys D342A8FB
gpg: sending key D342A8FB to hkp server keys.gnupg.net
➜ ~

You may omit specifying the keyserver if you have some listed in your ~/gnupg/gpg.conf

➜  ~  gpg --keyserver hkp://keys.gnupg.net --recv-keys D342A8FB
gpg: requesting key D342A8FB from hkp server keys.gnupg.net
gpg: key D342A8FB: "Bill Clinton " not changed
gpg: Total number processed: 1

In the same way, have your friends share their keys and you receive them into your keyring.

Here's another way to share your key.

-----END PGP PUBLIC KEY BLOCK-----
➜  Desktop

With that, you can do one of two things.

1. Save everything from BEGIN GPG PUBLIC KEY BLOCK to END GPG PUBLIC KEY BLOCK into a file. Then run gpg --import key.asc on that file assuming that is the name you gave it.

2. Type gpg at the command prompt. Now copy all from BEGIN line to END line and paste it into the command line. When done, hit control + d.

MORE USES OF GPG

Encrypt a string of text to Bill Clinton.

Software Using GNU GPG

Psi+ (It's made by Russian Monkeys with Wrenches!)

Install libqca2-plugin-gnupg and go to "Account Setup", Details tab, and select your key to use this feature in Psi+.

Seahorse (Included by default in Ubuntu ~~but somehow failed to be added to the menu this time in the 10.10 Maverick release~~, so type seahorse from the CLI. It's now under the System menu with the icon of keys.

FireGPG Firefox Extension http://getfiregpg.org

Alot of *nix users like to check their email with Thunderbird, Evolution, KMail or the best, Mutt. They all have built-in support for GPG except that Thunderbird needs Enigmail. A guide to using Mutt, the best way to check your mail, will take another blog post to do.

A complete list of software using GPG resides at http://www.gnupg.org/related_software/frontends.html

Now that you have gone nuts with encryption, Listen to the sounds of Evoken!

Activate Middle Mouse Click In Firefox

2010-11-11T10:41:00.000-08:00

Doing this will activate the middle mouse click and drag scrolling in Firefox. First, type in the address bar "about:config". Once you are there, ignore the silly message about voiding the warranty. Firefox does not come with a warranty. Do a search for general.autoScroll. Once you find that, right click it and choose "Toggle" to change its value from false to true.

Now you can close that tab for about:config and test your new settings.

Ultimate Tab Completion

2010-10-03T21:17:00.000-07:00

I recently switched my default shell to zsh. It has the ultimate tab competition. Watch the video to see how that works. Mostly everything else works the same as bash. I haven't found much if anything to work differently, just the better tab completion features mostly.

How I did it

First I installed zsh!
Next I used Oh My Zsh configuration.
I appended my own customizations to it (the bottom of .zshrc).
I'll explain each, so you can decide if you want to use any of that.

That includes

Using shift tab to do the reverse cycle through the tab completion as shown in the video
Everything typed by me in bold
Allowing comments while typing in zsh (not just scripts)
Importing my bash aliases and functions to zsh
And the same effect you normally get in Ubuntu when typing a command from a package that isn't installed.

Example of command not found working in zsh:

➜ Desktop twm
The program 'twm' is currently not installed. You can install it by typing:
sudo apt-get install twm
zsh: command not found: twm
➜ Desktop

With the Oh My Zsh configuration, you can change your prompt to some custom pre-made ones. I use the default because I like that one.

GNU Screen and configuration
(because I used it in the video)

Read here:
http://magazine.redhat.com/2007/09/27/a-guide-to-gnu-screen/

Here's my ~/.screenrc
Note: If you use this, change the directories to ones that exist on your computer

hardstatus alwayslastline
hardstatus string '%{= kG}[ %{G}%H %{g}][%= %{=kw}%?%-Lw%?%{r}(%{W}%n*%f%t%?(%u)%?%{r})%{w}%?%+Lw%?%?%= %{g}][%{B}%Y-%m-%d %{W}%c %{g}]'

# Default screens

chdir ~/
screen -t bash    0 /bin/bash
chdir ~/Coding/CS2213
screen -t zsh    1 # will run zsh by default
chdir ~/Hax0r
screen -t zsh     2 # will run zsh by default
chdir ~/
screen -t zsh     3

And then type screen and that config will be loaded.

Final Step

Now after you did all that, head to your gym and squat 385 lbs 2 times (or as many as you can till failure)

Hacking the Gnome Panel

I edited the C source code of of the gnome-panel for 64-bit Ubuntu 10.04 to allow more than 5 bookmarks/favorites showing, and then I compiled it back to a deb. The only part I forgot to do was change the package maintainers email to mine, so that the package would be gpg signed by my key. Don't worry, this won't affect using it at all. I didn't do anything like a dumbass not knowing what I'm doing. The max allowed bookmarks/favorites to show in the Places menu is now 20, probably much less than you'll use, so here are the debs for that. I did write in the channel log the change I made. If you want a 32-bit package, tell me in the comments/email.

or ...

http://nanomachine.zapto.com

If the first link fails and you use the second one, just browse over to the debs folder. I can add the deb for the mini-commander applet or you can read my blog post on how to create that yourself.

When you are done with all that goodness, go listen to some Evoken!

The laser on my mouse went out, so I plugged in a dual action Logitech gamepad that works out of the box with Linux, looks very similar to a playstation controller except black and blue, same buttons. Next I compiled qjoypad. My joysticks and gamepad buttons function well as a mouse, mouse buttons + more. movement is very smooth, much better than I expected. And this awesome gamepad only costs me $15 online. I knew it worked well/out of the box with Linux when I purchased it.

Go ahead; Try it!

2010-07-28T03:43:00.000-07:00

The software has been under heavy coding lately, big time. Travis M. is seeing what he can do with the code. I am short on time now for all the Projects I want to do due to college summer school, a week of break, and then transferring over to another University.

Preview Available For Download

2010-07-09T18:48:00.000-07:00

Download Link

For the Text To Speech Linux App!

Requirements:

xclip

openjdk or sun-java6-jre

libmiglayout-java is included until I make a deb that depends on it

mbrola and mb-en1

Known problems:

Speed slider is not implemented

Back button will not work more than once after text is read; It does work more once while text is being read.

Much more features to come!!! But before they do, I am now working hard to fix that last known problem I mentioned.

My Text To Speech App

2010-07-04T15:33:00.000-07:00

Here is a sneak preview of the software I am writing. If you knew how this work internally, it's very cool. What it does is reads text out loud from any application. There's no need to open files in it, though that option will still be there. Anything you can highlight text in, such as email or an article you found interesting in Firefox, an ebook in pdf format, etc, can be read. When Selection Buffer is selected, the text is read immediately after you let go of the mouse after highlighting some text. When clipboard is selected, it will read after you do you copy some text. The GUI (Graphics User Interface) is meant to be minimal size so that it can hover above other windows while you are using it to read text. It can expand and retract from a full GUI to a mini GUI. I do want to make a deb package of it. It does require certain dependencies such as either sun java or openjdk (either will work) and libmiglayout-java from the repos (I love MigLayout). Many more features are planned to be implemented including the choice between good voices to use. The forward and back buttons will go back and forward through what you are reading while it is reading one sentence token at a time. Have you ever read something to find out it didn't stick and you need to read it again? That problem is solved here through software :) Just hit the back button as many times as needed to go back some sentences and begin reading from there. This software will not be available for the Gates of Hell aka Windoze :)

And after you test this, go work on your triceps!

Have your IMs spoke to you with good voices

2010-06-16T03:37:00.000-07:00

When using Pidgin, and you receive an IM, you will hear it spoken to you, even if Pidgin is buried under many windows or on another workspace. Following these instructions will get you the good sounding voices, the pidgin plugin, the files necessary to use mbrola English voices with festival since the Pidgin plugin uses Festival. The last command just creates a .festivalrc file in your home directory that will fix issues with errors about /dev/dsp and not hearing the text being spoken. I've just done this today after much research, so I've saved you the time. I've been playing with and using Text to Speech for a long time, and I've been in the process of creating my own software. I could use some donations!!! Yes, I do have a working product, but I am expanding it big time and have great plans for it. Enjoy this. Be sure to go to your list of plugins in Pidgin when done and enable pidgin-festival, and choose between the voices that you have installed. us1 is a female voice btw. It will look like this when you go to configure plugin.

# Install the plugin
sudo apt-get install pidgin-festival 
# Install mbrola with all English voices available for it
# Yes, there is a question mark there. This bash globbing, matches mbrola-us1, mbrola-us2 and mbrola-us3
sudo apt-get install mbrola mbrola-en1 mbrola-us?
sudo apt-get install festvox-us? festvox-en1 # Again, use the question mark in the command
# Optional step
printf “;use ALSA\n(Parameter.set ‘Audio_Method ‘Audio_Command)\n(Parameter.set ‘Audio_Command \”aplay -q -c 1 -t raw -f s16 -r \$SR \$FILE\”)\n” | tee -a .festivalrc

When you are done, go lift 300 lbs like I did!!!

Removing history from Places - Saved Documents

2010-06-16T02:18:00.000-07:00

This is very simple. It works by preventing the history from being able to be stored (writable).

$ rm -f ~/.recently-used.xbel
$ mkdir ~/.recently-used.xbel
$ chmod 000 ~/.recently-used.xbel

I was suspicious about this program called BleachBit. To me it sounded like some yucky windows software that had made its way over to Linux. My suspicion was wrong. I will give you some warnings about using it.

http://bleachbit.sourceforge.net/

Go to the downloads page, scroll down and get the bonus pack to go with it as well.

This will clean house with all those messy dot files in your home folder among other things, and to my surprise, the first time I ran it, it removed a little over 1 gb of useless junk. Before deleting, look at a preview of what it will do to make sure that when you run it, it's not deleting something you had told it not to.

Do we really need language support for every language in all our programs? You can tell it which languages you will use and then it will go delete local files for all other languages that were not the ones you choose, for me, I kept Arabic, Spanish, and English, and the rest is not wasting space anymore

Here's a list of some things you may want to be sure are not checked.

Bash History
Saved Firefox Passwords (good to have a master password if you save them)
Nexuiz Cache, not sure if this will delete my custom maps I had downloaded so left unchecked
Pidgin Chat Logs (if you don't want these saved, then you should have them disabled in Pidgin)
Trash, I usually overview it before I empty it
System Logs, god no

It's all user preference though. If you don't have certain programs that it lists, it doesn't hurt to check them. Now that I've warned you, go use it. I have not had any problems, but if you do, I don't take responsibility. Go get mad at the developers :) or thank them for a nice program.

Software I am coding for Linux

2010-06-14T02:35:00.000-07:00

I am currently designing two software projects for Linux. One is working, and I just need to add to it. It's multithreaded and works just fine through the command line, but what I am about to do with it will blow anybodys mind away the way I have it designed. It will use some datastructures such as a Queue feeding one token at a time xD. I've written my own data structure. It would be very cool to incorporate that into the code, but it doesn't fit with what I am doing. ABSOLUTELY NO SOFTWARE MADE FOR LINUX EXIST WITH WHAT I AM CREATING!!!!!!!!! PERIOD!!!!! NOT EVEN WINDOWS CAN COMPARE TO THIS GODDAMN SHIT. I hit a roadblock, something new to me, and I am madly reading up on it and studying code examples. I know how to create multi-threaded applications and have done so, but when a gui is added to it, that changes things up, so now I am in the process of learning how to do it with Swing. But the GUI will take on the GTK gui interface if ran under Gnome. It will appear native to whatever environment it's run on, and since I don't care for Windoze, I won't bother to make sure it runs under that you suckers. If you have ever used TextAloud, this is similar to what I am creating for Linux except from a users point of view (me) knows what it is lacking and how to make it a ton better. I use this example because that is what most people are familiar with when it comes to text to speech software. Any text that can be selected can be read in a good sounding voice including your Optical Character Recognition.

As much as I want to jump to the second project which would be easier for me because I know how to do it without learning much new, I won't. I won't start a new project without finishing the one I started already.

Please, everything I do is for free and for the community. Please donate. The amount is not important. I guarantee you that it will speed up the process. Contact me for those wanting to see OSS and good free software to strive.

Linux Gamers and Windows Haters Can Rejoice

2010-05-12T15:50:00.000-07:00

A picture says a thousand words. What you see is not running through Wine. This native Steam Engine for Linux is in development right now. Just in this picture alone shows how many Windows apps have already been ported to Linux such as Hulu Desktop, Google Chrome and now Steam just in this picture. Valve says this work is due for release in the Summer. It is following the already released Steam for OSX. Helping gamers escape the Gates of Hell!!! A Google search string for the steam's site shows a script for Linux Steam.

Buggy Flash in 64-bit Linux Solved!

2010-04-10T16:35:00.000-07:00

I was having trouble with flash player in 64-bit Linux, especially with Youtube. What I did to solve this was remove the 32-bit flash plugin that's being used with emulation through nspluginwrapper and install the 64-bit flash player.

First,

Remove any packages installed that provided the file 32-bit libflashplayer.so. You can see where those files are by typing in a terminal:

locate libflashplayer.so

Optional: If you'd like to see which packages have installed a file, take one of the lines from the above command and type:

dpkg -S /location/to/libflashplayer.so

Be sure to replace /location/to/libflashplayer.so with your path to the file. dpkg -S can be used with any file that's been installed by a package and you want to see what package it belongs to.

In Ubuntu to remove these:

sudo apt-get purge flashplugin-*

Second,

Now to check that they are all gone:

sudo updatedb
locate libflashplayer.so

If the libflashplayer.so files are not all gone, use the rm command to remove any that are still there. Otherwise, skip to the next step.

Example:

rm ~/.mozilla/plugins/libflashplayer.so

Third,

Now go to Adobe's website to get the latest 64-bit flash player plugin and place it in the directory Firefox looks for plugins. The link for download is near the bottom of the page.

http://labs.adobe.com/downloads/flashplayer10_64bit.html

Create a directory to put the plugin in.

mkdir -p ~/.mozilla/plugins

Move the file you downloaded to ~/.mozilla/plugins in your user's home directory. If you are using the file browser to do this, hit control + h to see hidden folders (those ones that begin with dots, in this case the .mozilla directory, are hidden folders).

Next, extract libflashplayer.so from the tar.gz file you downloaded.

cd ~/.mozilla/plugins
tar -xf libflashplayer-10*linux-x86_64.so.tar.gz

I am using * (a wildcard) because the version you download when reading this may be newer than at the time of me writing this guide. You can substitute libflashplayer-10*linux-x86_64.so.tar.gz for the full filename. After extracting the file libflashplayer.so, you may delete the .tar.gz file you downloaded.

Fourth,

Test that the it is working. Restart Firefox for it to use the new 64-bit flash plugin. Now you should have a 64-bit libflashplayer.so file in ~/.mozilla/plugins. To verify that it is 64-bit, use the file command.

$ file libflashplayer.so 
libflashplayer.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, stripped

In Firefox, open a new tab (control + t) and type in the address bar "about:plugins" without quotes. You should see this.

As well as in Tools->Add-ons->Plugins, you should see this.

If you have all this, great! If not, leave a comment on this blog, and I will help you.

Now navigate to a web page with flash content that was giving you problems/bugs in the past and see if you are still experiencing those problems. For me, I am no longer having issues with Youtube.

Please leave a comment if this or any other blog posts has helped or been useful to you. I don't receive donations. At least a thank you would be nice.

Troubleshooting,

Thanks to OgreArtist and naomi for providing this information.

If you are still experiencing problems, try backing up your bookmarks and passwords. Then rename the ~/.mozilla directory to something such as ~/.mozilla_backup. Be sure to recreate the ~/.mozilla/plugins directory and copy the libflashplayer.so back to it. For backing up passwords, I like to use the Password Exporter Firefox extension. On some systems, you may have additional files to uninstall/remove such as npwrapper.libflashplayer.so. I had not needed to do either, but if you are still experiencing problems, you can try these.

Facebook Chat Through Instant Messenger App

2010-03-18T06:29:00.000-07:00

Facebook chat can now work under Linux again through your favorite IM application that supports the open xmmp protocol. One of my favorites is Psi. Empathy, Pidgin, and Kopete should work fine as well. Instructions are here.

Microsoft wants to add you to their shitlist

For those who wanted to be able to play their games using microsloft's proprietary application programming interface (api) called DirectX or purchased a phone not knowing that the software on it was called windows mobile, and required an activated purchased copy of Windows to get the memory card on the phone to show up as a drive, etc., may be subject to vendor lock-in, and obtained a modified copy of Windows that's pre-activated.

One of these World of Warcraft addicts I will call Pirate Joe that use Windows to play his WoW for endless hours has pre-activated copy of Windows. Pirate Joe installed this update, but so far his Windows is not broken by the update or Windows Genuine Advantage (WGA). So then what is MS doing with the information obtained for users using known exploits to bypass WGA and Activation?

Here's a closer look at the update marked as important.

Fortunately there are efforts such as Wine (providing an open source implementation of the windows API and DirectX for gaming) that have had good success getting users around vendor lock-in.

A Headache for some Linux Users

2010-03-02T13:33:00.000-08:00

Have you ever been playing a Game in Linux, kicking some noob butt and, the screensaver comes on while you are playing a game? Or have you watched watched a movie you downloaded and the screensaver comes on? I am not sure if a bug fix has been released, but for those experiencing the problem, there is a nice way of working around that problem with an application called Caffeine. It prevents the screensaver and standby while it's running with a coffee icon in your panel.

SSH PROXY AND SOPCAST

2009-11-27T10:40:00.000-08:00

This moderately complex how-to applies when we have no access to: broker.sopcast.com e.g.:
ping broker.sopcast.com - returns 100% packet loss and the user wants to use its services.

Sopcast is well known p2p internet tv platform. See http://www.sopcast.com .
broker.sopcast.com is the tracker which finds peers and makes sopcast network function normally.

Prerequisites:
1. tsocks - available for debian and ubuntu , probably every distro may have it.
2. ssh client (usually typing ssh in terminal is enough)
3. shell (ssh) access to a pc from whose internet we can freely ping broker.sopcast.com :)
Step 3 seems the toughest but you ask a friend to give you ssh access to watch some sport event on sopcast.
Actual steps for making sopcast work even when we cannot ping broker.sopcast.com :

1. Run in terminal: ssh user@sshaccess.com -D 8000

Please note -D 8000 which is important - it leaves port 8000 on localhost (127.0.0.1) open and bound to sshaccess.com - our ssh remote example server. That should be a kinda ssh tunnel :)

2. Run in terminal: sudo vi /etc/tsocks.conf - edit the end of file where things look like:
###############
server = 127.0.0.1
# Server type defaults to 4 so we need to specify it as 5 for this one
server_type = 5
# The port defaults to 1080 but I've stated it here for clarity
server_port = 8000
# 8000 is the port we set earlier - if you set another , edit accordingly , 127.0.0.1 remains.
###############

3. Export some command line variables (in terminal) borrowed from the tor's torrify howto in their wiki:

http_proxy=http://127.0.0.1:8000/
HTTP_PROXY=$http_proxy
export http_proxy HTTP_PROXY

Pay attention to the port 8000 - my example started with it and I stick to it :)

5. Start sopcast with that weird command line :

tsocks sp-sc sop://211.152.36.38:3912/6015 8900 8200

Where:
tsocks invokes sp-sc loading this sopcast address sop://211.152.36.38:3912/6015 which is the address of discovery channel in sopcast.
If you need more sopcast addresses try to figure them out here:
http://www.sopcast.com/gchlxml
8900 is localport - I chose that number randomly , you may choose freely here
8200 is the port where the stream on our pc will be , mplayer or vlc will need it, also possible to put any port you like.

5. Finally use mplayer or vlc to watch the local stream that sp-sc produces using that command.

mplayer http://127.0.0.1:8200/

In conclusion I might add that if you put a little imagination after understanding this example it should be possible to use sopcast over tor , although I find that unethical and slow , never tried it. But if you lack the ssh access mentioned in the 3rd prerequisite - tor would be your last resort.
Enjoy.
