Set Max File Size System Wide – All Users – Ubuntu

Sometimes, a game server process can crash continually until it is manually restarted.  When this happens, the log file it creates fills up with the same error until the ENTIRE server runs out of disk space.  To prevent that from happening, limit the maximum size a file can grow to by adding the following line to the end of the /etc/profile file to apply it to all users.

ulimit -f 52428800

The above numeric value is kilobytes.  It is set to 50GB in the command above.

Restart the server for it to take effect.

Windows XP, Vista, and Windows 7 .NET 4.0 Post Slow Startup Fix

I've been running my main machines on Windows XP x64 for several years, and I am a .NET developer.  There came a day when I needed .NET 4.0 for my development projects.  After installing .NET 4.0 in Windows XP x64 SP2, I noticed a slow bootup despite the fact that I have a solid state drive.  Windows would always boot up and freeze for about a minute before the network LAN and Wireless LAN computer icons appeared in the system tray.  At first, I never realized the problem was caused directly from the install of .NET 4.0.  For over a year I tried troubleshooting the problem.  I noticed that I had this problem on all of my XP machines after installing .NET 4.0.  I suspected video drivers, LAN drivers, wireless LAN drivers, and even my BIOS.  Nothing fixed this issue.  After further searching, I finally found a thread describing the same issues I was having.  Save yourself the read, and just run this batch file I wrote after installing .NET 4.0 on ANY Windows XP x64 or x86 machine:

set I=%windir%\
%I:~0,2%
cd %windir%\Microsoft.NET\Framework\v1.1.4322

sc config "clr_optimization_v4.0.30319_64" start= disabled
@echo off
echo.
echo. All operations have been completed successfully.  The .net 4.0 framework services were disabled, as they are no longer needed.  This will not affect .net 4.0 applications, and your startup boot time should be back to instant!
pause

This script is useful on all versions of Windows.  If you have a slow startup, try running this to see if it improves the situation!
