Linux - change resolution in text mode on LCD screen

if you watch small about 80 chars terminal output in the middle of yours gigantic LCD screen..

you should try to change screen resolution. It depends on your distribution (Fedora, Ubuntu or Red Hat) and boot manager.
I am using Fedora Project 17 on VMWare with GRUB2.
Lets modify /etc/default/grub

#try to set native monitor resolution

GRUB_GFXMODE=1024x768

#force to keep graphic mode

GRUB_GFXPAYLOAD_LINUX=keep

Yes, that's right, modern terminals running text mode over graphic gfxterm

to apply changes lets execute

 
grub2-mkconfig -o /boot/grub2/grub.cfg

and reboot

Now you should see the text in entire screen.

Enjoy!

mysql errno 1251 Client does not support authentication protocol requested by server

mysql errno 1251 Client does not support authentication protocol requested by server
OR
unable to connect database server in my php 4.4.9 script.

I have spent some time before found out that php 4.4 isn't compatible any more with mysqld 5.1
Some thought you can find here. Solution of the problem is simple. You must correct user's password and save it in old style.

mysql> SET PASSWORD FOR
    -> 'some_user'@'some_host' = OLD_PASSWORD('newpwd');

apache: main default host is not accessible

I have added VirtualHost and can't access main DocumentRoot from httpd.conf :(
According to RTFM

Main host goes away

If you are adding virtual hosts to an existing web server, you must also create a <VirtualHost> block for the existing host. The ServerNameand DocumentRoot included in this virtual host should be the same as the global ServerName and DocumentRoot. List this virtual host first in the configuration file so that it will act as the default host.

Ok, i have added VirtualHost directly to httpd.conf and it doesn't help me at all. Why?

Because above of VirtualHost Directive was Include ..\conf.d\*

Hmmm...  Who says you can't teach a old fox new tricks?...

Just add new config file in conf.d directory and it must be first file.
Let's create conf.d/aaaa_default.conf file with content

#first VirtualHost is default

<VirtualHost *:80>

    ServerAdmin webmaster@firsthost.tdl
    DocumentRoot /var/www/html
    ServerName firsthost.tdl:80
    ServerAlias localhost

    ErrorLog  /var/log/httpd/error_log
    CustomLog /var/log/httpd/access_log common

</VirtualHost>

Whoops!!!! The file is loaded first because name(!) and corresponds to my default path.

Some useful settings in LogFormat are
 %f - local filename
%v - virtualhost name

LogFormat "%v %l %u %t \"%r\" %>s %b %f" common

Please note that i am using apache as httpd rpm from fedora core. Other distributive can be slightly different.

Enjoy!

Notepad++ - new User Defined Language (UDL2)

UDL (User Defined Language) is one of most important features in Notepad++.

In v6.2, much better UDL system (UDL2) is provided by Ivan Radic (aka Loreia). Not only many restrictions/limitations in UDL are removed, but also a lot of new features/enhancements are added in UDL2. In fact, you can almost define any language with it.

The key features of UDL2 are:

1. More keyword groups were added (more syntax highlighting can be defined):

• 3 folding groups
• 8 keyword groups
• 2 comment groups
• 1 number definitons
• 2 operators groups
• 8 delimiter sets

2. Multipart keywords are supported (for example: "else if" can be defined as a single keyword)

3. Whitespace is no longer mandatory as keyword separator: Operators, Delimiters and Folding keywords can be recognized with or without whitespace separators.

4. Numbers recognition support is greatly improved (prefix, suffix, range and extra symbols supported).

5. Operators and delimiters can be longer than one character.

6. The same characters can be used as comments AND operators.

7. Comments and delimiters support nesting (even within each other).

8. Improvments to Comments include:

• Comment folding
• Comment continuation
• Comment only start at the beginning of line

9. In the case of several comment pairs defined, comment open symbols match only with comment close symbols of the same order. (for example: /* C comment */, /+ D comment +/, but not /* mixed comment +/)

OTRS default search ticket number

You can enable default search by ticket number in SysConfig with option

Ticket::Frontend::AgentTicketSearch###Defaults###TicketNumber

OTRS add custom CSS style

Wrong way to add it directly to HTMLHead.dtl file.

Correct way to create new Custom.css file, save it into /var/httpd/htdocs/skins/Agent/default/css/ directory
and add Custom.css item to Loader::Agent::CommonCSS###000-Framework via SysConfig editor.

 Enjoy!
