The information about new PS2 emulator for a bit list of operation systems was dicovered in world wide web. Offical website of Play! emulator is https://purei.org/ . I thought it could be a good idea to test the pre-compiled build for Linux. But errors were found:

There was error connecting bluetooth headphones in Ubuntu (xfce) 16.04 : "Connection Failed: blueman.bluez.errors.DBusFailedError: Protocol not available".

One of the solutions is installing bluetooth module for pulseaudio

1) sudo apt-get install pulseaudio-module-bluetooth
2) pactl load-module module-bluetooth-discover

or

sudo service pulseaudio restart

or

pkill pulseaudio

3) Remove device from the list and try to pair it again.

Sometimes you need to transliterate filenames from cyrilllic to latin in Linux. Doing this manually could take a lot of work if number of files over 10. Installing new software for this tiny thing is not my choice and I just dont want to do it.

Today was the first time I could not unpack rar file since I've started to use Linux in everyday use that! The issue was in unrar-free version - it can't unpack RAR files after 3.x version.

[timestamp] [core:notice] [pid 20056] AH00060: seg fault or similar nasty error detected in the parent process

File transfer was not working from laptop to smartphone and vice versa. Devices connected to each other without problems.

There is a plugin TransferService in Plugins section. When I've tried to wnable it the message with error was shown:

There was error running Half-Life on Source engine in Ubuntu 14.04 error was thrown.
Unable to load interface VGUI_Surface030 from vguimatsurface.so

If Vagrant shows the message on vm start this means that virtual machine can't boot. And there is no case to connect through SSH.

STOP 0X00000074 (0X0000000000000002, 0XFFFFF88002E22B20, 0X0000000000000002, 0XFFFFFFFFC000009A)

If you get BSOD STOP 0X00000074 error on Windows booting,  you must to boot from bootable Windows DVD installation disc.
Run bcdedit commnad from Recovery console and type next commands.

bcdedit /deletevalue {default} numproc
bcdedit /deletevalue {default} truncatememory

Those commands would change quantity of processors and maximum memory option.

Sometimes there could be an issue with huge DB which was created not with backup_migrate module but raw mysqldump command. The size of the DB could be over 2GB. Most of the data of this dump are cache tables and logs. Editing this file is not a good choice.

Current solution will remove INSERTS from the file. sed command come in handy here:
