Relatd: I’ve used Linux containers directly and indirectly for years, but I wanted to become more familiar with them. So I wrote some code. This used to be 500 lines of code, I swear, but I’ve revised it some since publishing; I’ve ended up with about 70 lines more. I wanted specifically to find a minimal set of restrictions to run untrusted code. This isn’t how you should approach containers on anything with any exposure: you should restrict everything you can. But I think it’s important to know which permissions are categorically unsafe! ...

Related: This is the manifest of things I’ve learned about managing CSS in large, complex web projects during my many years of professional web development. I’ve been asked about these things enough times that having a document to point to sounded like a good idea. I’ve tried to keep the explanations short, but this is essentially the tl;dr: Always prefer classes Co-locate component code Use consistent class namespacing Maintain a strict mapping between namespaces and filenames Prevent leaking styles outside the component Prevent leaking styles inside the component Respect component boundaries Integrate external styles loosely » Jarno Rantanen | github.com | via css-tricks.com

CockroachDB is a distributed SQL database. The primary design goals are scalability, strong consistency and survivability (hence the name). CockroachDB aims to tolerate disk, machine, rack, and even datacenter failures with minimal latency disruption and no manual intervention. CockroachDB nodes are symmetric; a design goal is homogeneous deployment (one binary) with minimal configuration and no required external dependencies. » Spencer Kimball | github.com

First of all we have to define what is meant by ‘composition’. Composition refers to the way the various elements in a scene are arranged within the frame. As I’ve already mentioned, these are not hard and fast rules but guidelines. That said, many of them have been used in art for thousands of years and they really do help achieve more attractive compositions. I find that I usually have one or more of these guidelines in the back of my mind as I’m setting up a shot. ...

Somewhere, way down at the bottom of the list of requirements, behind, fast, cheap, and flexible is “secure”. That is, until something goes wrong, until the system you build is compromised, then suddenly security is, and always was, the most important thing. Security is a cross-functional concern a bit like Performance. And a bit unlike Performance. Like Performance, our business owners often know they need Security, but aren’t always sure how to quantify it. Unlike Performance, they often don’t know “secure enough” when they see it. ...

Al principio me molestaba en calcular métricas sobre el código fuente (utilizaba cosas como Source Monitor para ello), que me indicaran número de líneas de código, complejidad ciclomática, nivel máximo de anidamiento, profundidad de jerarquías…., en fin todo tipo de datos para disfrutar con un poco de porno de estadísticas. Además, analizaba la cobertura de código que alcanzaban mis tests (con NCover, si no recuerdo mal), y tenía configurados mis avisos si no llegaban a determinados niveles. ...

There are a lot of ways to work with color on the web. I think it’s helpful to understand the mechanics behind what you’re using, and color is no exception. Let’s delve into some of the technical details of color on the web. » Sarah Drasner | css-tricks.com

I don’t know anything about music. I know there are letters but sometimes the letters have squiggles; I know an octave doubles in pitch; I know you can write a pop song with only four chords. That’s about it. The rest has always seemed completely, utterly arbitrary. Why do we have twelve notes, but represent them with only seven letters? Where did the key signatures come from? Why is every Wikipedia article on this impossible to read without first having read all the others? ...

If you’re reading this page, chances are that you’re already well aware that E.T. for the Atari 2600 is one of the most reviled games ever made. I never understood why. As a child, it was one of my favorite games. I still think it’s a good game. Apparently, I’m not alone. On this page I’m going to briefly explore why people hate E.T., and how the game can be fixed. ...
