Render Multimedia in Pure C
In a previous article I demonstrated video filtering with C and a unix pipeline . Thanks to the ubiquitous support for the ridiculously simple Netpbm formats — specifically the “Portable PixMap” ( .ppm , P6 ) binary format — it’s trivial to parse and produce image data in any language without image libraries. Video…

Google Wave's Scrollbars
In spite of some of the reaction to it , I find Google Wave to be surprisingly useful. One thing I don't really understand, though, is its scrollbars. They behave quite differently from regular scrollbars, and I can't discern any overwhelming advantages of Google's implementation. It seems I'm not alone. The…

How to Write with Style (1985)
Newspaper reporters and technical writers are trained to reveal almost nothing about themselves in their writings.

Fast high-level programming languages
Python and R are slow when they can’t rely on functionality or libraries backed by C/C++. They are inefficient not only for certain algorithm development but also for common tasks such as FASTQ parsing. Using these languages limits the reach of biologists. Sometimes you may have a brilliant idea but can’t deliver a…

A Random Walk Through Ada (2014)
So the C programming language has been getting a lot of bad press recently; a really stupid bug in some C code has compromised some of the core security infrastructure on the internet. The fix is easy, but the knock-on effects are going to go on for years and will cost serious amounts of money. As a result, people…

Swift 5 switches the preferred encoding of strings from UTF-16 to UTF-8 while preserving efficient Objective-C-interoperability. Because the String type abstracts away these low-level concerns, no source-code changes from developers should be necessary*, but it’s worth highlighting some of the benefits this move gives…
