Ubuntu tip: Turning off tooltips

2011-12-22T18:00:00.004+08:00

When you hover over anything in Ubuntu Yellow boxes pop-up (Tooltips) and give you information. Personally it bugs me really badly. If you are like me; turning them off is really simple.

Note: the quotation marks are not part of the names.

First right click on the "Applications" button in the top panel, then click "Edit Menus". e.g:

When the menu editor opens click "System Tools". In the right column you will see: "Configuration Editor" Tick the box next to it, and close the menu editor. e.g:

Now click on "Applications" then "System Tools" then "Configuration Editor". Once the configuration editor opens click the arrow next to "apps", then click the arrow next to "panel". This expands the menus. e.g:

Now select the "global" folder. and in the right column untick the box next to "tooltips_enabled". e.g:

There you have it. Annoying yellow boxes gone :)

Solution: Disable tooltip in Kubuntu 11.10

SSH Login Without Password

2011-10-13T15:24:00.001+08:00

Follow this step from the machine that you want to get access to remote machine

Step 1: Create public and private keys using ssh-key-gen on local-host

patelm@local-host$ [Note: You are on local-host here]
patelm@local-host$ ssh-keygenGenerating public/private rsa key pair.
Enter file in which to save the key (/home/jsmith/.ssh/id_rsa):[Enter key]
Enter passphrase (empty for no passphrase): [Press enter key]
Enter same passphrase again: [Pess enter key]
Your identification has been saved in /home/patelm/.ssh/id_rsa.Your public key has been saved in /home/patelm/.ssh/id_rsa.pub.
The key fingerprint is:f3:58:0d:f8:65:d6:8f:95:8B:11:89:1a:e5:d6:b0:64 patelm@local-host
The key's randomart image is:
+--[ RSA 2048]----+
|          .E.oo  |
|         oo.=o+ .|
|        . +++o.o.|
|         o.*   + |
|        S o . . .|
|         =       |
|        . .      |
|                 |
|                 |
+-----------------+


Step 2: Copy the public key to remote-host using ssh-copy-id
patelm@local-host$ ssh-copy-id -i ~/.ssh/id_rsa.pub remote-host
patelm@remote-host's password:
Now try logging into the machine, with "ssh 'remote-host'", and check in:

.ssh/authorized_keys

to make sure we haven't added extra keys that you weren't expecting.

Note: ssh-copy-id appends the keys to the remote-host’s .ssh/authorized_key.

Step 3: Login to remote-host without entering the password
patelm@local-host$ ssh remote-host
Last login: Sun Nov 16 17:22:33 2008 from 192.168.1.2
[Note: SSH did not ask for password.]

patelm@remote-host$ [Note: You are on remote-host here]

wrong fs type, bad option, bad superblock - nfs

2011-10-10T10:14:00.001+08:00

mount: wrong fs type, bad option, bad superblock on 10.1.1.1:/home/nfs,
       missing codepage or helper program, or other error
       (for several filesystems (e.g. nfs, cifs) you might
       need a /sbin/mount. helper program)
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

All of this was because crunchbang does not come with nfs-common installed, so if run into this problem, run:

sudo aptitude install nfs-common

If you are working with Arch Linux, type this:

sudo pacman -S nfs-utils

And the problem will go.

This is not fixed .. fixed, but indeed it will stop annoying error message avalance.

Installing Microsoft Truetype fonts on Ubuntu

2011-10-04T14:38:00.001+08:00

You can install the MS core fonts by installing the msttcorefontspackage. To do this, enable the “Universe” component of the repositories. This is done by default in Feisty. After you do that, use the following command from the command line:

$sudo apt-get install msttcorefonts

This will give you the core fonts, but if there are other TrueType fonts that you want installed, it is as easy as copying the font files to the~/.fonts/ directory.

After installing new fonts, you will have to log out and log in again to be able to see and use the new fonts. If you want to avoid this, you can regenerate the fonts cache by issuing the following command:
$sudo fc-cache -fv

Solution : warning: extended initializer lists only available with -std=c++0x or -std=gnu++0x

2011-09-30T13:48:00.001+08:00

you are initializing the object with {...} instead of (...):

StatsScreen ss{...}; // only available in C++0x
StatsScreen ss(...); // OK in C++98

To compile your code as C++0x code, just add the following flag when compiling:

g++ test.cpp -std=c++0x

Printing ® character in PDF which is created with tcpdf [PHP]

2011-09-26T22:04:00.000+08:00

When you create UTF-8 PDF document with tcpdf and you want to write some html symbols then you have to encode that character symbol to utf-8.

e.g.
$description = "Hello ® World"
echo str_replace('®', utf8_encode("\xae"), $description);

It will write ® to PDF instead ® text. [Output in PDF document : Hello ® world]

'ae' is the hex value of the ® symbol.

For more symbol to hex value please follow this link : http://allwebco-templates.com/support/S_hex.htm

2011-09-14T10:11:00.001+08:00

When building the RPM if you get this issue that means you have forgot to define Patch0 at top

ex. if you patch file is x-0.patch add the follwing line at top of spec file

Patch0: x-0.patch
