In this post I'm going to explore how a mathematical concept can be redefined in progressively more computer-oriented terms, all the way from high level languages down to machine code, ready for direct execution by a computer. To that end, I'm going to define the same logic in several different but related formats:
Of all the programming styles I have learned, dynamic programming is perhaps the most beautiful. It can take problems that, at first glance, look ugly and intractable, and solve the problem with clean, concise code. Where a simplistic algorithm might accomplish something by brute force, dynamic programming steps back…

Thank you for attending a training session! We covered a lot of ground, so these notes are meant to serve as a reference and reminder of the advice we gave you.
Another of those values that has seeped into everyday life from start up culture is the cherished status of risk. You know the inspirational quotes people like to post on Twitter “the biggest risk is not taking a risk”, “those who will not risk, will not win” etc. And I get it, personally and professionally it’s…
Explorers planning to settle on Mars might be able to turn the planet’s red soil into bricks without needing to use an oven or additional ingredients. Instead, they would just need to apply pressure to compact the soil—the equivalent of a blow from a hammer. These are the findings of a study published in Nature…
One unfortunate (albeit entirely predictable) consequence of making HTTPS certificates “fast, open, automated, and free” is that both good guys and bad guys alike will take advantage of the offer a…

The Forces That Call for Microservices
At Twitter, a team had a unusual failure where corrupt data ended up in memcache. The root cause appears to have been a switch that was corrupting packets. Most packets were being dropped and the throughput was much lower than normal, but some were still making it through. The hypothesis is that occasionally the…
Here follows the original "manifesto" from late 2014 proposing the idea for what became Upspin . The text has been lightly edited to remove...
No matter if you are a software developer, a copywriter or you are just writing an e-mail, you need to have in mind these text traps.

Programing in Clojure and ClojureScript
Most of today's cryptography is designed to be secure against an adversary with enormous amounts of computational power. This means estimating how much work certain computations require, and choosing cryptographic parameters based on our best estimates.
SciPy—a NumFOCUS Affiliated Project —recently crossed a major milestone for any open source project: version 1.0! NumFOCUS extends our hearty congratulations to all of the SciPy contributors and community members who helped get the project to this point.
Performance is everybody’s responsibility, no matter what your role. When it comes to the GPU, 3D programmers have a lot of control over performance; we can optimize shaders, trade image quality for performance, use smarter rendering techniques… we have plenty of tricks up our sleeves. But there’s one thing we don’t…
At Kolide, part of what we do is build a client-server system that facilitates the management of large, isolated installations of an open-source tool called osquery. While I’ve written and spoken about osquery in the past, in this post I want to focus on how we use Go to solve many of the challenges we face building…
