Once upon a time, we had a single monolith of software, one mothership running everything. At SoundCloud, the proliferation of microservices came from moving functionality out of the mothership. There are plenty of benefits to splitting up features in this way. We want the same benefits for our data as well, by defining ownership of datasets and ensuring that the right teams own the right datasets.

Last week I participated in two hackathons, events where a group of strangers would form a team for two or three days and build a product prototype. In the end all teams pitch their prototypes, and the best ones would be given some prizes. Hackathons are typically organized to get feedback from developers on some new API or platform. Sometimes they’re also organized as a recruitment opportunity. Apart from the free beer and camaraderie,....

I always imagined death to be a very uniquely individual experience. I always imagined how I would cope with the death of a loved one, how I would deal with my grief, how I would find peace and regain normalcy. Although it seems obvious now, in all those hypotheticals, I never accounted for all the others going through the same thing. Like a black hole in the space-time continuum, death has a ripply, sucky effect, affecting everyt..

When I first created this site I wanted to get it live as quickly as possible. Hexo , a blogging framework written in Node.js, seemed like the perfect tool. At the time I was rather interested in Node.js, so it seemed natural to use a framework rooted in that community. By the time of my last post I'd become increasingly disinterested in Node.js and much more interested in Rust and its community. It was mostly procrastination, but I conv..

1400 words, 5 minutes. The Tay Bridge disaster occurred during a violent storm on 28th December 1879 when the first Tay Rail Bridge collapsed while a train was passing over it from Wormit to Dundee, killing all 70 people aboard. It is widely accepted by engineers that disasters teach us more than successes. Said another way, we don’t learn from the bridge that stays standing. After the Tay Bridge disaster there was an investigation.

Cisco RV130 Router Manual (PDF) Issues I set up a network - a router, two access points, a few switches and ~ 15 to 20 devices. Issues that need to be resolved: I want to be able to access the network from the outside. I want to give priority to VOIP devices. Privacy errors when trying to access Google sites (google.com, youtube.com, gmail.com). Access Network from the outside ¶ Now the network looks like this:

Obvious Facts About Box Trucks #2: They're Great For Moving Things

I knew embarrassingly little about The Box™ when I bought it. I spent weeks obsessing over what kind of vehicle I wanted, but I purchased my current home of two years after only an hour or so of looking it over. For example: I had the truck for nearly a month before I figured out it used to be a moving truck. More specifically, it used to be a Budget truck, and I just had no idea. I only found out by chance observation; if you look clo..

Recently, I’ve become interested in the so-called “funnel method” of character creation in the RPG Dungeon Crawl Classics. The funnel is a process of deriving your 1st-level character by running a handful of 0-level commoners through a dungeon and seeing who comes out the other side alive. A group of players would need to funnel […]

Chapter 7 of “The Linux Programming Interface” is about memory allocation. One of the exercises, marked as advanced, asks the reader to implement malloc . I’ve decided to give it a shot. My full implementation is available on Github . I will try to break down some of my reasoning on the next sections and include some snippets from the code. Memory layout of a Process The memory allocated to each process is composed of multiple segments,..

A quick post. I was looking at the prices to install a home battery system the other day. During the sales process I was informed that for a modular system such as the one provided by Ampetus that if you don’t buy 2 or more batteries that “you may de rate system capacity” Sound’s impressively scary! Slightly worried I asked that it means. Thankfully what it actually means is that instead of getting 3kW delivery using two batteries t..

I’ve been meaning to talk more about my “Sublime Text and BBEdit” workflow, and this is a powerful (if mundane) example. I don’t write a ton of scripts on my Mac and generally don’t spend much time in Terminal. But when I need a script, I really need a script . My work is very file-heavy. I juggle large numbers of .tex (LaTeX) files across several large folder structures. Every so often I need to copy a subset of files within one folde....

Following my read of “The Linux Programming Interface”, I came across the concept of “file with holes” or “sparse files”. Those are files that try to use the file system more effectively by preventing it from using disk space when sections of the file are empty. The disk storage is only actually used when needed. Sparse files are really useful for backup utilities, disk images, database snapshots etc. One way to create a sparse file is by..

This post is a sequel to Formulating the Support Vector Machine Optimization Problem. The Karush-Kuhn-Tucker theorem Generic optimization problems are hard to solve efficiently. However, optimization problems whose objective and constraints have special structure often succumb to analytic simplifications.
