blog.ksplice.com is the company blog at blog.ksplice.com, writing about systems and security. Since 2010, 30 different Hacker News readers have linked it 48 times, most often “How to write a filesystem in 50 lines of code”. No feed was found, so read it on the site itself.
Too few sampled comments (10) to say how often HN recommends it.?
Why HN links it
HN readers link long, in-depth posts on kernel and low-level systems hacking, such as libc-free programs, cosmic-ray kernel fixes and process management. Commenters call it a favourite.
Summarised by Claude from a sample of 10 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

HN discussionAt least part of the "fun" on a loosely modern operating system is learning the nuts and bolts of the executable format and loading conventions. I've never spent much time there, but some of the ideas are laid out well in this two part post: http://blog.ksplice.com/2010/04/libc-free-world-2/ Doing it with _just_ a hex editor (ie writing out the ELF headers and sections yourself) may not be exactly what the commenter…

HN discussionCan someone give some insight on the last line? That's it. Simple. Now you can launch the hello program by entering ./hello. Look at the binary size -- surprised? Without being able to compile the executable myself, is the binary surprisingly large or small? A few months ago, someone posted this article: http://blog.ksplice.com/2010/03/libc-free-world/ Which leads me to believe that the executable is surprisingly la…

HN discussionLooks like their blog is down too ( http://blog.ksplice.com ). This was by far one of my favorite blogs. Good, long, articles about kernel hacking. I hope it comes back up soon and isn't gone for good.

HN discussionThe article references some great modules for those actually writing perl code. For those that never learn to write full apps in perl, there are still a few gem 1-liners that are worth tucking away. For instance, perl -pi.bak -e 's/something/something_else/g' *.erl would act as a global substitution with backups (any file changed would have an original x.erl.bak). A list of some other useful 1-liners can be found he…
