http://askubuntu.com/questions/9853/how-can-i-make-rc-local-run-on-startup Can you run your script manually? If not, it's a problem with that script; otherwise look more at rc.local. (If that script needs to run as root, you need use sudo to manually run it.) Make sure /etc/rc.local is executable and that the script it calls is also executable.$ ls -l /etc/rc.local -rwxr-xr-x 1 root root 419 201..

http://www.perl.com/pub/2004/08/31/livecode.html Hacking Perl in Nightclubs By Alex Mclean on August 31, 2004 12:00 AM I've found the experiences of dancing and programming to have a great deal in common. With both I am immersed in an abstract world of animated structures, building up and breaking down many times before finally reaching a conclusion. Indeed, when the operation of even the dulles..

http://nakkaya.com/2010/08/24/a-micro-manual-for-lisp-implemented-in-c/ Recently I had to go through some code that uses the uIP TCP/IP stack, which reminded me, it has been a long time since I did something in C so I ended up spending the weekend implementing the 10 rules John McCarthy described in his paper A Micro-Manual for Lisp - not the whole Truth. This is a literate program, the code in ..

http://felix.plesoianu.ro/scratch-lang/ This is a 5-part tutorial on how to implement a programming language. It is intended for people with some programming experience, who want to know how their compiler, interpreter or virtual machine works. Hint: it's not magic. There are many articles (even books!) on this topic. I'm writing mine with two purposes in mind: to keep it short and easy to follo..

http://mwultong.blogspot.com/2008/03/eof-ascii-code-end-of-file.html 16진수 헥사로 1A 번인 아스키 코드가 EOF 문자입니다. 십진수로는 26번에 해당합니다. "End of File"의 약자입니다. "텍스트 파일의 끝"을 의미합니다. 이진파일일 경우에는 파일의 끝이라는 의미로 사용되지 않고 일반 데이터로 간주됩니다. 원래 이 문자는 이런 → 오른쪽 화살표로 보이는데, 편집기에 따라서는 화살표가 아닌 공백으로 보이는 경우도 있습니다. 콘트롤 문자로는 ^Z 로 표현됩니다. 도스에서 키보드의 Ctrl+Z키를 누르면 EOF 문자가 찍힙니다. 원래 옛날의 도스용 텍스트 편집기에서는 파일의 맨 끝에 EOF 문자를 자동으로 붙이는 경우가 많았지만, 지금의 편집..
