ไม่มีอะไรทำ พรุ่งนี้สอบ

ไอ้แมงมุม

สีฟ้าสีโปรด

Firefox หมาไฟ

หัดเขียน php

ฟังเพลง(สุชาติ) + java , gcc (version)

ตั้งแต่กลางปีมาไร้สาระไปวันๆ ไม่ค่อยมีอะไร ไว้ปีใหม่ค่อยกลับมาเริ่มเขียนให้มัรมีสาระมากกว่าแปะลิงค์ หรือโชว์รูป

CPU Usage Limiter for Linux

Posted in Linux by Noyzi!!a on the August 25th, 2007

cpulimit is a simple program that attempts to limit the cpu usage of a process (expressed in percentage, not in cpu time). This is useful to control batch jobs, when you don’t want they eat too much cpu. It does not act on the nice value or other scheduling priority stuff, but on the real cpu usage. Also, it is able to adapt itself to the overall system load, dynamically and quickly

Examples of use

Limiting the program ‘bigloop’ by executable name to 40% CPU:
$ ./cpulimit --exe bigloop --limit 40
or
$ ./cpulimit --path /usr/local/bin/bigloop --limit 40
Limiting a program by PID to 55% CPU:
$ ./cpulimit --pid 2960 --limit 55

iTALC - Intelligent Teaching And Learning with Computers

Posted in Linux by Noyzi!!a on the August 24th, 2007

iTALC is a use- and powerful didactical tool for teachers. supports Linux and Windows 2000/XP/Vista.

What is iTALC?

iTALC is a use- and powerful didactical tool for teachers. It lets you view and control other computers in your network in several ways. It supports Linux and Windows 2000/XP/Vista and it even can be used transparently in mixed environments!

In contrast to widely used commercial equivalent software, iTALC is free! This means you do not have to pay for expensive licenses or things like that. Furthermore the source-code is freely available and you’re free in changing the software to fit your needs as long as you respect the terms of iTALC’s license (GPL). Freedom in two ways!

Features

iTALC has been designed for usage in school. Therefore it offers a lot of possibilities to teachers, such as

see what’s going on in computer-labs by using overview mode and make snapshots
remote-control computers to support and help other people
show a demo (either in fullscreen or in a window) - the teacher’s screen is shown on all student’s computers in realtime
lock workstations for moving undivided attention to teacher
send text-messages to students
powering on/off and rebooting computers per remote
remote logon and logoff and remote execution of arbitrary commands/scripts
home-schooling - iTALC’s network-technology is not restricted to a subnet and therefore students at home can join lessons via VPN-connections just by installing iTALC client

Furthermore iTALC is optimized for usage on multi-core systems (by making heavy use of threads). No matter how many cores you have, iTALC can make use of all of them.
Some clients in overview-mode with opened welcome-screen

Some clients in overview-mode with opened Classroom-Manager
