i know c language.my goal read linux kernel.so languages should learn(write books too) before start reading kernel , there book reading linux kernel this book little outdated, understanding linux kernel amazing reference. give crash course in i386 features make lot of kernel facilities possible (such mmu , how interrupts work. operating systems, it's hard understand hardware ends , os begins), , reference lot of critical source directly. also, lwn kernel article index more up-to-date references. one way start come simple feature you'd add kernel , start hacking away @ it. (something did in college count how many times each process got preempted , export value via /proc file system. taught me lot scheduling, /proc, process structure, , many other facilities). recommendation, in vm unless plan reboot every fifteen minutes. for ad hoc questions, searching google works, or asking questions on irc.

what happening when write array[i] = '\0' inside loop? char arraypin[256]; for(int = 0; i<256; i++) { arraypin[i] = '\0'; } the program attempts access memory @ location of <base address of 'array'> + (<sizeof array element> * 'i') , assign value 0 (binary 0, not character '0'). operation may or may not succeed, , may crash application, depending upon state of 'array' , 'i'. if array of type char* or char[] , assignment operation succeeds, inserting binary 0 @ position 'i' truncate string @ position when used things understand c-style strings ( printf() being 1 example). so if in for loop across entire length of string, wipe out existing data in string , cause interpreted empty/zero-length string things process c-style strings.

are there web hosting providers have pysvn ( http://pysvn.tigris.org/ ) included in python modules, or allow add additional modules such can install myself? many thanks. if have shell access can install pretty home directory. make sure path install module added pythonpath environment variable. say /home/harry home directory, install pysvn /home/harry/lib in .bash_profile add: pythonpath=/home/harry/lib:$pythonpath export pythonpath login , log out again. put environment , python find modules in /home/harry/lib see python docs on modules more info on how python searches modules. the real caveat is, if host doesn't have files needed build pysvn (such svn header files), you'll have install them also. with said webfaction (which nice towards these things , python development) , question might better in webmasters.stackexchange.com
