  • Remembering the LAN

    We can have the LAN-like experience of the 90's back again, and we can add the best parts of the 21st century internet. A safe small space of people we trust, where we can program away from the prying eyes of the multi-billion-person internet. Where the outright villainous will be kept at bay by good identity services and good crypto.

    The broader concept of virtualizing networks has existed forever: the Virtual Private Network. New protocols make VPNs better than before, Wireguard is pioneering easy and efficient tunneling between peers. Marry the VPN to identity, and make it work anywhere, and you can have a virtual 90s-style LAN made up of all your 21st century devices. Let the internet be the dumb pipe, let your endpoints determine who they will talk to based on the person at the other end.

  • Predicting Hard Drive Failure with Machine Learning

    These data points are labelled as members of the negative or positive class, which in this case means “hard drive operates normally” or “hard drive has failed.” Note that the “positive” in “positive class” doesn’t mean “good.” Instead, it means “this sample exhibits the behavior we’re looking out for.” A machine learning model would read this dataset, then look for patterns in the features that determine why each hard drive ended up in its class.

    Normally there would be enough data points and features that a human couldn’t read the whole dataset—let alone spot a pattern in it! This example is simplified enough for us to step through the process that a model might follow. Let’s look for a pattern in each feature:

  • Escape from System D, episode VII

    Well, it’s been an awfully long time since I last blogged about Dinit (web page, github), my service-manager / init / wannabe-Systemd-competitor. I’d have to say, I never thought it would take this long to come this far; when I started the project, it didn’t seem such a major undertaking, but as is often the case with hobby projects, life started getting in the way.

  • Doing «Data Science» even if you have never heard the words before

    I’d like to shatter some of this mystery today. Let’s do some machine learning, find some patterns in our data – perhaps even make some predictions. With good old Python only – no 2-gigabyte library, and no arcane knowledge needed beforehand.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
