This is a parser for HTTP messages written in C. It parses both requests and responses. The parser is designed to be used in performance HTTP applications. It does not make any allocations, it does not buffer data, and it can be interrupted at anytime. It only requires about 128 bytes of data per message stream (in a web server that is per connection).

The goal of the SafeStr library is to provide a rich string-handling library for C that has safe semantics yet interoperates with legacy library code in a straightforward manner. Additionally, porting code that uses standard C string handling should be straightforward. The library should work on all modern Unix-like platforms, as well as any 32-bit Microsoft Windows OS. The overt security goals of the library are as follows: 1. Buffer overflows should not be possible when using the API. 2. Format string problems should be impossible when using the API. 3. The API should be capable of tracking whether strings are "trusted", a la Perl's taint mode. The API is meant to provide rich functionality and be easy to use, all the while improving security.
C’est quoi “Protocol Buffer” ? C’est le mécanisme qu’utilise en interne Google pour sérialiser des données structurées lors d’échanges entre des systèmes ou des applicatifs. Mais aujourd’hui on fait çà en XML non ? Exact, mais la majorité des développeurs, surtout quand il s’agit ne s’agit pas de systèmes documentaires, n’ont jamais vraiment aimé XML.

No software is bug free, and application users can encounter unexpected results during the run time of programs. To analyze and find the cause of problems, logging is a method widely used by programmers. In this article, learn how to use a ring buffer for efficient logging with memory operations in place of file operations.

How can an application request a report using a control transfer? How can an application send a report using a control transfer? How can an application request reports using interrupt transfers? How large is the ReadFile buffer? Where is the Windows documentation for accessing HIDs? Why do I receive "CRC Error" when attempting to send a report to my device? ...

Hard disk utility which has the following functions: Benchmark: measures the raw performance. Hard Disk information which includes partition information, supported features, firmware version, serial number, disk capacity, buffer size, transfer mode.
Popular screen readers use a virtual buffer to allow users to interact with web content. This article uncovers undocumented behaviour in JAWS 7.1 and later, which allows web developers to build Ajax applications that update the virtual buffer without any interaction from the user

GNU ddrescue is a data recovery tool. It copies data from one file or block device (hard disc, cdrom, etc) to another, trying hard to rescue data in case of read errors. Ddrescue does not truncate the output file if not asked to. So, every time you run it on the same output file, it tries to fill in the gaps. The basic operation of ddrescue is fully automatic. That is, you don't have to wait for an error, stop the program, read the log, run it in reverse mode, etc. If you use the logfile feature of ddrescue, the data is rescued very efficiently (only the needed blocks are read). Also you can interrupt the rescue at any time and resume it later at the same point. Automatic merging of backups: If you have two or more damaged copies of a file, cdrom, etc, and run ddrescue on all of them, one at a time, with the same output file, you will probably obtain a complete and error-free file. This is so because the probability of having damaged areas at the same places on different input files is very low. Using the logfile, only the needed blocks are read from the second and successive copies. The logfile is periodically saved to disc. So in case of a crash you can resume the rescue with little recopying. Also, the same logfile can be used for multiple commands that copy different areas of the file, and for multiple recovery attempts over different subsets. Ddrescue aligns its I/O buffer to the sector size so that it can be used to read from raw devices. For efficiency reasons, also aligns it to the memory page size if page size is a multiple of sector size.
kses is an HTML/XHTML filter written in PHP. It removes all unwanted HTML elements and attributes, and it also does several checks on attribute values. kses can be used to avoid Cross-Site Scripting (XSS), Buffer Overflows and Denial of Service attacks.
