This page provides technical articles related to computer sciences essentially in the Linux environment. A french version of some of them have been published in GNU Linux Magazine France. You can find the most recent of them here.
|Redirection of Linux logging into systemd
|How the usual Linux logs resulting from a call to syslog() are redirected into the systemd's journal and then eventually redirected to the standard legacy daemons such as rsyslogd or syslog-ng.
|Cleanup of huge page files
|How to write an implicit cleanup of the backing files of the huge pages when an application terminates.
|Detailed approach of the futex
|The System V semaphores provided by Unix and later by Linux, are quite heavy from a performance point of view.
With the futex coming from the researches of H. Franke, R. Russel et M. Kirkwood, a
more efficient alternative is available.
This article aims at presenting the implementation details of the futex in the Linux kernel and how to use them as well as how the open sources libraries benefit from them.

|Playing with SIGWINCH
|Description of the Linux SIGWINCH signal and how to manage it.
|Make a lightweight system() service
|Description of various solutions (especially ISYS and RSYS based on PDIP) to optimize applications using libc's system() service.
|Whirlwind tour of cmake
|Empirical approach to cmake through examples of applications.
|Design of an API for FTP clients
|This is an introduction to the FTP protocol along with the description of the source code of the FTP client API ROOF.
|Using pseudo-terminals to control interactive programs
|How to use pseudo-terminals (pty) to control interactive programs. This is an introduction to PDIP.
|Best practices for the C language preprocessor
|Description of various tips to use the C preprocessor efficiently for the sake of the robustness, portability and debuggability of the programs.
