In my previous blog post on pointer provenance, I have shown that not thinking carefully about pointers can lead to a compiler that is internally inconsistent: programs that are intended to...
C++ has changed a lot in recent years. The last two revisions, C++11 and C++14, introduce so many new features that, in the words of Bjarne Stroustrup, “It feels like a new …
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…
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…
It’s been nearly four years since I published Parsing Protobuf at 2+GB/s: HowI Learned To Love Tail Calls inC.In that article, I presented a technique I co-d...
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…
This is the first article in a series dedicated to multiple dispatch - an advanced abstraction technique available to programmers out-of-the-box in some languages, and implementable in others. This first post in the series presents the technique and explains the problem it intends to solve. It uses C++ as the…
Sometimes I see unsourced, unclear, vaguely mystical claims about K being the fastest array language. It happens often enough that I'd like to write a long-form rebuttal to these, and a demand that the people who make these do more to justify them.
In your build tools, you may have noticed that you have an ECMAScript 3 target, and 5 and up, but never a 4. Why is that?
For a while now, the Ruby community has become enamored in the latest new hotness, evented programming and Node.js. It's gone so far that I've heard a number of prominent Rubyists saying that JavaScript and Node.js are the only sane way to handle a number of
Looking for operator or function names? Well have a look at the following and remember using existing one may ease the transition :)
Checked exceptions have always been a controversial feature of the Java language.
Overture to our small Lisp to x86-64 compiler
Topics : monads, Common Lisp, functional programming Author : Marijn Haverbeke Date : July 11th 2008
Many people who use Rust for a bit - especially those who like the language but do not fall in love with it - feel a sense that there must be a smaller, simpler variation on the same theme which would maybe be a little less powerful, but would also be much easier to use. I agree with them, but I think they are almost…
This post is now a part of the official rust book In my previous post I talked a bit about why the RWlock pattern is important for accessing data, …
Back in 1996, having heard horror stories about Herbert Schildt's C: The Complete Reference , I decided to check it out. I flipped the book open; I found glaring errors. I paged through it. I found more glaring errors. In short, the book had lived up to the hype; it was awful. Being a pedantic sort, and having just…
Today marks the end of a crazy six year journey for me at Microsoft. I clearly remember my brutal first 8 months at this company as I worked with lawyers, marketing folks and execs to figure out if and how we could release IronPython as an open source project from Microsoft. The final approval for that release came…
A question is infrequently answered either because few people know the answer or because it concerns an obscure, subtle point (but a point that may be crucial to you). I thought I had invented the term for my Java IAQ , but it also shows up at the very informative About.com Urban Legends site. There are lots of Python…
Recently I had to go through some code that uses the uIP TCP/IP stack, which reminded me, it has been a long time since I did something in C so I ended up spending the weekend implementing the 10 rules John McCarthy described in his paper A Micro-Manual for Lisp - not the whole Truth .
A favorite conundrum of many Lisp aficionados is why the language appears to languish in disuse. Talk of cultural problems , "the library question" (which usually boils down to nonsensical circular reasoning), too many parentheses, and other absurdities simply dances around the blindingly obvious explanation - one…
Reviewing the JIT in Python 3.13
Previous posts Why Go is not my favourite language and Go programs are not portable have me critiquing Go for over a decade.
This is my closing talk ( video ) from the GopherConAU conference in Sydney, given November 10, 2023, the 14th anniversary of Go being lau...
You can check out a YouTube recording of a talk based on this blog post.
I've also ended up using Emacs along side Jetbrains IDEs (PyCharm & Webstorm). It is an odd combo but it works great. Emacs for mind-control level text editing, and the IDE works great for mouse-oriented poking around and small edits.
I’ve been enamoured with languages in the Lisp family ever since I first encountered The Structure and Interpretation of Computer Programs now more than a decade ago. At the time I was disappointed that such beautiful systems found so little use in day to day programming. Lisp seemed both deeply pragmatic (Objects!)…
This text is a transcript of a presentation I have given on October 9, 2015, at the CityCode conference in Chicago. This content is also available in video , and as a PDF Document better suited for printing.
