Download mb2md.pl script and run as described in manual.
For example to convert /old/mbox to /new/maildir you can execute:
# perl ./mb2md.pl -s /old/mbox -d /new/maildir Converting /old/mbox to maildir: /new/maildir Source Mbox is /old/mbox Target Maildir is /new/maildir Dummy mail system first message detected and not saved. 40 messages.
How to use physical hard disk in VirtualBox
January 29th, 2012
Brak komentarzy
To use physical hard disk in VirtualBox you need to create image that represents it.
This can be done by issuing the following command (Windows):
VBoxManage internalcommands createrawvmdk -filename D:\hdd_phy_1.vmdk -rawdisk \\.\PhysicalDrive1
For more relevant information look at VirtualBox manual.
Dell N411z – “GLX” missing on display “:0.0″
January 28th, 2012

I use Dell Inspiron N411z with Intel HD Graphics 3000 and recently I run into problems with 3D support. I suppose it happened after I installed something but don’t remember exactly what.
glxinfo output on broken system:
$ glxinfo name of display: :0.0 Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Error: couldn't find RGB GLX visual or fbconfig [...]
You can see below which packages I removed (xserver-xorg-video-all is a meta-package and got removed just by dependency so other drivers are intact).
Start-Date: 2012-01-26 02:27:53 Commandline: /usr/sbin/synaptic Remove: nvidia-current:amd64 (280.13-0ubuntu6), nvidia-settings:amd64 (280.13-0ubuntu2) End-Date: 2012-01-26 02:28:35 Start-Date: 2012-01-26 02:35:42 Commandline: /usr/sbin/synaptic Remove: xserver-xorg-video-all:amd64 (7.6+7ubuntu7), xserver-xorg-video-ati:amd64 (6.14.99~git20110811.g93fc084-0ubuntu1), fglrx:amd64 (8.881-0ubuntu4.1), fglrx-amdcccle:amd64 (8.881-0ubuntu4.1), xserver-xorg-video-radeon:amd64 (6.14.99~git20110811.g93fc084-0ubuntu1) End-Date: 2012-01-26 02:36:19
Then I restarted X server and now everything works fine.

Most hosting providers doesn’t provide file manager application but there is an easy solution as you can use AjaXplorer. It a web based file management software (PHP based and Open Source application!).
Host your own cloud service
January 26th, 2012
Brak komentarzy
I was searching for easy cloud service recently. My findings were less then satisfactory – just client applications, no WebDAV support or high prices.
Then I found ownCloud. It has couple of strong points:
- Open source, PHP based so it can be hosted without any special requirements
- Easy, clean and configurable interface
- WebDAV support for file manangement
- CalDAV support for calendar synchronization (although I got problems with Journal entries)
- CardDAV support for contacts synchronization
Unfortunately here at home.pl I can forget about WebDAV support which made me angry today.
WordPress – How to quickly create rewrite rules for all posts
January 25th, 2012
Brak komentarzy
This post describes a quick way to create .htaccess rewrite rules after permalinks change from /%post_id% to /%year%/%monthnum%/%day%/%postname%/.
Using phpMyAdmin execute sql code:
SELECT id AS ID, date_format( post_date, "%Y" ) AS Y, date_format( post_date, "%c" ) AS M, date_format( post_date, "%d" ) AS D, post_name AS name FROM `wp_posts` WHERE post_status = "publish" ORDER BY `wp_posts`.`id` ASC
Export results to CSV file with columns separated by ; character and without header in the first row.
$ head wp_posts.csv 12;2010;11;29;how-to-access-cli-on-linksys-srw 42;2010;11;29;how-to-use-imagemagick-effects-with-coppermine 99;2010;11;30;having-problems-with-some-ie-only-web-interface-using-firefox 100;2010;12;01;nginx-proxy-and-real-ip-address 101;2010;12;01;nginx-and-gandi-ssl-certificate 102;2010;12;02;https-everywhere 107;2010;12;03;ruby-and-rmagick-quote-with-polaroid-like-effect 108;2010;12;04;zen-photo-polaroid-like-effect 110;2010;12;03;zen-photo-and-nginx-rewrite-rules 112;2010;12;03;linux-like-environment-for-windows
After file is stored in local file system you can use awk to generate rewrite rules:
$ awk -F\; '{print "Rewriterule ^" $1 "$ http://blog.sleeplessbeastie.eu/" $2 "/" $3 "/" $4 "/" $5 "/ [R=301,L]"}' wp_posts.csv

Funny thing happened today. I got really surprised that using CTRL + F keyboard short-cut executed xterm.
Then I realized that I installed xbindkeys recently…
How to print contents of virtual console terminal

Sometimes it a good idea to check or just store contents of virtual console terminal (/dev/vcs[1-63] device).
To print its contents execute command:
$ sudo cat /dev/vcs2 | fold --width 80 | \
sed -e 's/ *$//g' | sed -e '/^$/N;/\n$/d' | sed -e '${G}'CentOS release 5.7 (Final) Kernel 2.6.18-274.7.1.el5 on an x86_64 home login:
Depending on console dimensions width parameter needs to be adjusted.
$ sudo cat /dev/vcs4 | fold --width 170 | \
sed -e 's/ *$//g' | sed -e '/^$/N;/\n$/d' | sed -e '${G}'Ubuntu 11.10 notebook tty4 notebook login: milosz Password: Login timed out after 60 seconds. Ubuntu 11.10 notebook tty4 notebook login:
If you don’t care about empty lines at the end then use shorter version:
$ sudo cat /dev/vcs5 | fold --width 170 | sed -e '${G}'milosz@notebook:~/VirtualBox VMs/Ubuntu$ file * Logs: directory Ubuntu.vbox: XML document text Ubuntu.vbox-prev: XML document text Ubuntu.vdi: data milosz@notebook:~/VirtualBox VMs/Ubuntu$ ls -1 / bin boot cdrom dev etc home initrd.img initrd.img.old lib lib32 lib64 lost+found media mnt opt proc root run sbin selinux srv sys tmp usr var vmlinuz vmlinuz.old milosz@notebook:~/VirtualBox VMs/Ubuntu$ pwd /home/milosz/VirtualBox VMs/Ubuntu milosz@notebook:~/VirtualBox VMs/Ubuntu$ [...]
How to access contacts on rooted E10i phone
January 20th, 2012

I use rooted Xperia X10 mini (model E10i) with Android 2.1-update1. Unfortunately I couldn’t find any software for direct synchronization that runs on Linux so at least I wrote small script to backup my contacts.
#!/bin/sh su - << EOF cp /data/data/com.android.providers.contacts/databases/contacts2.db /sdcard/ EOF
After executing script on the phone (for example using Root Explorer or Terminal Emulator) I can copy it from SD card and open with sqliteman. It can be installed using command:
sudo apt-get install sqliteman
Now as you see on picture below it is quite simple to view contacts stored on the phone.
How to access sensor data

Install lm-sensors package:
$ sudo apt-get install lm-sensors
Execute sensors-detect command as root:
$ sudo sensors-detect
It will determine needed modules and at the end it will ask for your permission to automatically add them to the /etc/modprobe file. If you answered yes then load them using command:
$ sudo service module-init-tools start
Now you can use sensors command:
$ sensors acpitz-virtual-0 Adapter: Virtual device temp1: +44.0°C (crit = +100.0°C) temp2: +44.0°C (crit = +100.0°C) coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +45.0°C (high = +86.0°C, crit = +100.0°C) Core 0: +45.0°C (high = +86.0°C, crit = +100.0°C) Core 1: +44.0°C (high = +86.0°C, crit = +100.0°C)
