The PingCAP company, makers of the TiDB NewSQL database and the TiKV key-value store, have kindly made publicly available, as well as open-sourced, a set of training courses that they call the "PingCAP Talent Plan". These courses train programmers in writing distributed systems in the Go and Rust languages. They are…
Drago — a nice example of a real-world binary tree This was the first post about my book on algorithms and Lisp. Writing it, actually, st...
This is a psuedo-transcript for a talk given at Deconstruct 2019. To make this accessible for people on slow connections as well as people using screen readers, the slides have been replaced by in-line text (the talk has ~120 slides; at an average of 20 kB per slide, that's 2.4 MB. If you think that's trivial…
Some years ago someone asked whether it would make sense to switch Python to a PEG parser. (Or a PEG grammar; I don’t recall exactly what…
I'm the kind of person who reads encyclopedias front to back just for fun, and I've been fascinated by mathematical special functions at least since my first encounter with the gamma function as a teenager. My work implementing numerical and symbolic algorithms in mpmath , Arb and other software projects during the…
They’re not burritos.
It’s terribly punny/dorky of me, but reading your post it just occurred to me one could start a blog called “Race Condition” about being a person of color and being a computer scientist.
Client-side navigation is supposed to make your pages load faster. But when I tried it, it was actually slower! Why?
A friend and I had a discussion about the basic skills that are often lacking in experienced programmers. How can a programmer work for ten or twenty years and never learn to write good code? Too often they need close supervision to ensure they go down the right path, and can never be trusted to take technical…
This is an archive of the original "fsyncgate" email thread. This is posted here because I wanted to have a link that would fit on a slide for a talk on file safety with a mobile-friendly non-bloated format .
As it’s the 50th anniversary of the Apollo 11 moon landings, I thought this would be a great opportunity to live code a demonstration of using my new compiler to write a simple lunar lander game… but first, I’m going to port the compiler to generate code for an actual lunar lander. Yes, my target platform is the…
I had a bad week a few weeks back, and got together with a friend and former colleague. We started trading war stories. He mentioned one time when he was working for a company which had both a desktop client and a server component. The communication between the two pieces of the system was completely, utterly…
This article is based on historical research and on simply reading the Vim user manual cover to cover. Hopefully these notes will help you (re?)discover core functionality of the editor, so you can abandon pre-packaged vimrc files and use plugins more thoughtfully.
During the last few days there has been an ongoing Twitter storm about 10× developers. And like all the ones before it (and all the future o...
In parts 1 and 2 we saw:
You probably saw the big discussion this past weekend on Twitter about 10x Engineers. It all started with a tweet about how to recognize a 10x Engineer, followed by tons of responses about how usel…
I was curious when the famous programmers do their work. And it is quite easy to find. The result of programmers work is a code. Code is stored in version control systems (VCS). When you put code in VCS the time is record.
Programmers love to discuss programming languages. We not only debate their technical merits and aesthetic qualities, but they become integrated into our personal identities, along with the values and traits that we associate with them. Some even defend a form of Linguistic Determinism that thinking is confined to…
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…
The vertical scrolling effect in the original “The Legend of Zelda” relies on manipulating the NES graphics hardware in a manner that was likely unintended by its designers.
Software engineer specializing in query engines and distributed systems
Given the expansive growth in the field, it's become challenging to discern what belongs in a modern computer science degree.
Compilers, interpreters, runtimes, and the like can sometimes feel vaguely magical. They take your code, perform complex transformations that you only partially understand, and spit out an executable binary. Clearly, the inner workings of such a beast must contain arcane secrets, not meant for the minds of mortals.
Video and transcript of Jimmy Koppel's Compose 2019 talk on defunctionalization, the best refactoring you've never heard of.
This post is about uninitialized memory, but also about the semantics of highly optimized “low-level” languages in general. I will try to convince you that reasoning by “what the hardware d...
Warning: All of this doesn’t really follow any best practices for working with html, css or javascript - on the contrary: what we will be doing may look horrible to some people, and rightfully so - so you may not want to try those things at work just yet.
Evaluating Rust as the common denominator of modern development
Cedarwood is an effort to speed up jieba-rs , an efficient implementation of trie is needed in order to satisfying the following needs.
