Despite the fact that the NVIDIA Jetson Nano DevKit comes with Docker Engine preinstalled and you can run containers just out-of-the-box on this great AI and Robotics enabled board, there are still some important kernel settings missing to run Docker Swarm mode, Kubernetes or k3s correctly. So, let’s try to fix this… Analyzing the Linux Kernel In my last blogpost Verify your Linux Kernel for Container Compatibility , I already sh....

The first time I saw wdired in action, it blew my mind. wdired makes dired (directory editor) buffers writeable, so you can edit them like any other Emacs buffer. You can subsequently use all your favorite file-editing tricks to rename files (amongst other things). You can see it in action at the end of Emacs Rocks episode 16 . When combining find-dired with wdired, one can easily find matching files and quickly batch rename them u....

Previously in compiler basics: 1. lisp to assembly 2. user-defined functions and variables 3. LLVM Next in compiler basics: 5. LLVM system calls 6. an x86 upgrade In this post we'll extend the compiler 's LLVM backend to support compiling conditionals such that we can support an implementation of the fibonacci algorithm. Specifically we're aiming for the following: $ cat tests/fib.lisp ( def f....

I had a hard time getting Sublime Text to work with Marked 2 , back when I used Brett’s app to proof my writing. Dan Sturm posted a simple snippet that launched it using a build system, that failed if Marked came from the App Store. Here’s the fix: Permalink.

Maestro is a library we have developed to handle all playback across SoundCloud web applications. It successfully handles tens of millions of plays per day across soundcloud.com, our mobile site, our widget, Chromecast, and our Xbox application. We are considering open sourcing it, and this blog post is a technical overview of what we’ve achieved thus far with Maestro.

I’ve had a very particular itch for a long time, now. Something I love about open source is that it empowers developers to scratch their own itches, and a while back I decided to do exactly that. We’ve used it in production on the Nextcloud snap for a few months with relatively few issues, so I think it’s time to open it up for wider use… in case you share my itch.

I Recently complete a basic ncurses based terminal application for minglinng with bits. I’m working low level most of the times and need to tinker with bits, masks and to translate between number bases (hex to dec, and vice verse). As I’m working 99% of my time in a terminal, I found it very annoying […]

A few days ago, I decided to start an article about my writing setup. Over the years I have dialed it in, and today I have a pretty neat workflow. As I started on that piece, though, I realized that I had never talked about why I write in plain text. Most aspects of my workflow traces back to that choice, so today I want to explain some of the reasons I made it. Permalink.

When I first moved to the Bay area I was fresh out of grad school. I was frequently heading out to dinner or to happy hour after work with colleagues. I was young and single, so why not of course. As time passed, marriage, kids, etc. the ability to go out for a quick drink or dinner was competing with various priorities. Dinner and drinks with co-workers was always a great time. It wasn’t just about hanging out, it built rapport and trust w....

Avoiding Javascript also means missing out on cool tricks like these, that make writing good code easier when we have no choice but to use it. I work hard to optimize the Python behind this site , but did almost nothing with the 400 lines of uncommented Javascript code behind my LMTV RV builder . I have some serious work ahead of me on that project, and simple tips like these from Antonio Sanchez will make that a lot easier. Permali..

Responsibility is only possible by granting ownership and setting expectations. If you don't turn over ownership, don't expect folks to take responsibility. When you grant ownership and set expectations, you'll be astounded what folks will accomplish without you. I am astounded.

Klimaat en de politiek Global warming: het is een hot topic de laatste tijd. Het speelde een grote rol in de afgelopen Tweede Kamer verkiezingen (2017), met Jesse Klaver van Groenlinks als voornaamste aanjager. En met success, GroenLinks won flink. Mede hierdoor werd er vanaf 2018 een groot polder project gestart: het Nederlandse klimaat akkoord. Ook bij de afgelopen Provinciale Staten (en dus indirect de eerste kamer) verkiezingen was h..

Are you sure whether your Linux kernel is able to run Containers in an optimal way, or if there are still some missing kernel settings which will lead to some strange issues in the future? Normally you don’t have to bother about this question. When you’re using Docker and Containers on a modern Linux system or on a public cloud offering, this has been already optimized by the Linux distribution or your cloud provider. But when you star....

Dominik Vacikar measured growth signals for 4,000 companies, then searched for historical correlations between those signals and stock market performance. His research lead to some interesting results that he plans to turn into an interest product. This reminded me of my work on a Hacker News scraper , a project I hope to revive soon. Permalink.

Caddy is the swiss army of the web server, and with the recent commercial license changes, it’s time to give it some love back. I have several static websites, some generated with Hugo, some are plain HTML. I wanted a small container, to run it inside a Kubernetes cluster, capable of pulling some git repos and serve them. Caddy-git Caddy is already capable of that with the help of caddy-git unfortunately it is only working with ssh keys.

I talked about my road to weightlifting the other day, to give you insight into my background. Having reached each end of the fitness spectrum, and after going back and forth between extreme conditioning and extreme strength, I look forward to sharing with you the lessons I learned along the way. As I work to regain the strength I lost over the last month, I want to highlight some of the consequences of that decision. In doing so, I hope ..

When trying to send an email, using JavaMail , from my application deployed via the Jetty web server in Docker , I kept on getting the following errors: java.lang.NoClassDefFoundError: javax/activation/DataSource Caused by: java.lang.ClassNotFoundException: javax.activation.DataSource OK so with the upgrade from Java 8 to Java 11, due to Java 9 Project Jigsaw, a lot of things have been “removed” from the JVM.

In his 2016 piece Marginal Gains , he went over some small tips to make developers’ lives easier. He had some good suggestions, and I want to take a minute to emphasize one of his points. Use the command line as much as possible, so that you can automate as much of your work as possible. Most programs wrap....

I interact with a lot of people in a given week, a few in person and far more on video and conference calls. I don’t claim to be a perfect person to talk to on the phone, but over the past several years I’ve noticed how painful some conference call experiences can be. As more and more work is conducted virtually and not face to face an ability to do communicate well on conference/voice calls is tied to what success you can deliver. It isn’....
