MONO compile error mono CS1566: Error reading resource file `big5.table'

I stumbled upon an error while compiling MONO:

mono CS1566: Error reading resource file `big5.table'

It turned out that I had moved the catalog with MONO source code without saving permissions and omitting hidden files - I just packed them folder with GUI KDE compress tool.

 When you want to move the source to another machine: use good old console tar.

to compress:
tar cvzpf compressed.tar.gz ./folderToCompress

to decompress:
tar xvzpf compressed.tar.gz

Windows - 7zip default temp directory

If you extract an extremely large file (like > 50 GB or so) and you end up with no space - the 7zip application can hang. Where should you look for the extracted file that is locking your HD space?

The default 7zip temp directory is:

c:\Users\user_name\AppData\Local\Temp\

Windows - register VirtualBox VBox machine in a single *.bat file from *.vbox file in the current working directory folder

To register VirtualBox machine in a single *.bat file from *.vbox file in the current working directory folder on Windows use the following commands:

"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" registervm %~dp0\MonoSuse.vbox
"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" registervm %cd%\MonoSuse.vbox

OpenSuse Mono enable binding on low port numbers/ open low ports

1. You need to install "capabilities" library on OpenSuse.
zypper install libcap-progs
zypper install libcap1
zypper install libcap2

2. Allow mono to bind on low ports numbers:

setcap 'cap_net_bind_service=+ep' /usr/bin/mono-boehm

Now you'll be able to run .NET programs that bind on port numbers (below 1024) that are traditionally reserved for root (require root privileges). Traditional UNIX implementations distinguish two categories of processes: privileged processes (whose effective user ID is 0, referred to as superuser or root), and unprivileged processes (whose effective UID is nonzero). Privileged processes bypass all kernel permission checks. In order to run a process as non-root and bind to a port <1024 you need to give that binary a net_bind_service capability.

Drop/Create a postgresql database from script/ from console

$echo your_postgres_user_password | sudo -S -u postgres psql -c "create database database_name"

$echo your_postgres_user_password | sudo -S -u postgres psql -c "create database database_name"

OpenSuse 12.3, MonoDevelop 4.0.12 - no source code visible, no code visible in CodeView, gray windows instead of code

After compiling MonoDevelop from clean source no code is visible in the editor - instead a clean, gray window is displayed. To resolve the issue just export an appropriate env variable:

export OXYGEN_DISABLE_INNER_SHADOWS_HACK=1

and then run monodevelop as you'd normally do:

$ monodevelop

OpenSuse 12.3 Postgresql autostart start at boot

$su
#systemctl start postgresql.service
#systemctl enable postgresql.service

"start" starts the postgresql server and the "enable" part is supposed to start the server at boot.
