The future scares me. Not in a “the icecaps are melting” sense, more of a “what am I doing with my life” sense. I spend a lot of my words on this blog talking about the future. Saving for it. Planning for it. Picking travel destinations. So imagine my surprise when I sat down one day to think about it, and I found that I had no idea what I actually wanted to do with my life.

Do you remember the thrilling re-entry scene at the end of the movie Gravity ? The Chinese space station Tiangong-1 is orbiting at thousands of miles per hour when (spoiler) it dips fatally into the Earth's upper atmosphere. The drag buffets and tears at the station’s components before the increasing friction finally flashes the air around the station into a glowing plasma, reducing the station to a shredded sparkling field of debris. We..

Recently, I’ve started working on a new project. It will take some time before the goal of the project is even worth mentioning. The important part is that it is an electronics/hardware project and it needs an energy efficient computing unit. For early development I chose an ARM Cortex M3 STM32F3 microcontroller. More precisely STM32F303K8T6 , mostly because I have a Nucleo board, with this chip, laying around. It’s also a good time ..

The practical take-away from this post is that if you’re ever trying to debug serial communications with a device that — against all tradition — only transmits when the Data Terminal Ready line is clear (devices should normally do the opposite: transmit only when Data Terminal Ready is set), then never run stty on the serial port to double-check your settings. Why? Because stty turns Data Terminal Ready back on. Without even asking you..

It is very easy to make assumptions about a subject you know well and others may not. You will have knowledge you have learnt over time that you perceive is so simple or obvious that others should just know it - forgetting that once you too had to learn it. This article sums it up really well with the word … “just”.

Prefer Lombok's `@SneakyThrows` to rethrowing checked exceptions as `RuntimeException`s

The traditional way of dealing with a checked exception being thrown from a place where you know it can’t actually be thrown, is to re-throw it as a RuntimeException. That way in case it does actually happen, you’ll know about it, and have the full stack trace available. public void foo() { try { Writer w = ..... w.write("foo"); .... } catch (IOException e) { throw new RuntimeException(e); } } Project Lombok offers the annotatio..

The most common way for Snyk users to find out that they have an issue in their project is via our email alerts. It’s a core part of our service, but until recently, we didn’t have much in the way of configuration around what types of issues would trigger an email alert. As we scale our language support, enabling you monitor more projects in Snyk, we want you to feel better informed about the types of issues that matter to you, while making..

I’m currently reading The Box by Marc Levinson. It is a fascinating book that chronicles the changes in the shipping industry brought about through the introduction of shipping containers. It sounds dry, but it’s not. The innovators faced huge barriers, including governments, labour unions, and standards committees. I have such deep respect for Malcom McLean for persisting through the insurmountable bureaucracy. At one point, they ..

In this post we’re going to see a handy technique to create and use stubs for your Elixir projects, leading to better tests, more maintainable code, and a lot of fun while using ETS, match specs, and macros. 15-20 minute read Let’s jump right in: Untestable code As an example, let’s say you have a module that uses some dependency to query DynamoDB (although note that this could be any other type of external service ), and your code lo....

One challenge engineering teams often face is dealing with work that doesn’t revolve around developing new features but that still requires the team’s attention and time. The Content Engineering Team here at SoundCloud is no exception, so we iterated on a process to deal with unplanned and support tasks to end up with fewer interruptions and more time to spend on implementing planned features.

Tai-Danae Bradley is one of the hosts of PBS Infinite Series, a delightful series of vignettes into fun parts of math. The video below is about the same of SET, a favorite among mathematicians. Specifically, Tai-Danae explains how SET cards lie in (using more technical jargon) a vector space over a finite field, and that valid sets correspond to lines. If you don’t immediately know how this would work, watch the video.

Score: 4.5 / 5 Paul Graham and his editor(s) are excellent. His prose is light and easy to follow. The only awkward component of the book's organization is that he tends to use a concept one section before explicitly introducing and defining that concept. I'm not sure yet if this is a good or bad thing. As a learning resource Among books recommended to potential Lispers, ANSI Common Lisp is typically written off. Graham's style of Lisp i....
