Awesome! MicroBus 3, what does that mean? Well, I've been using Semver (mostly, sometimes a little Ferver creeps in) for my package versions…

We finally got a decent recording of one of my favorite talks. This one is about our Incremental library (which I wrote about here ), and in particular about the story of how we got to the present, quite performant, implementation.

If you read this blog, you know I’ve recently released a project called regionagogo, a geo shape lookup database, described in this blogpost. It uses the current Go S2 implementation, which is not yet as complete as the C++ implementation, for example the region coverer of a shape does not really compute cell around the shape but around the bounding box instead. Using the shape of the polygon makes the covered cells more precise and smaller..

There’s nothing that beats the feeling of being part of an exceptional team and yet it is strangely difficult to define exactly what makes one team great and another team not-so-great. Google recently set out to learn how to build the perfect team and came up with some interesting, albeit previously discovered, answers. To summarize their findings, Google’s Project Aristotle concluded that on good teams: All team members spoke roughly..

There are a lot of cases when we want to track time when an entity was created or updated. Here is a simple recipe to make some or all of your SQLAlchemy entities auto-timestamping. To achieve this, we will provide a mixin class. from datetime import datetime from sqlalchemy import Column, DateTime, event class TimeStampMixin(object): """ Timestamping mixin """ created_at = Column(DateTime, default=datetime.utcnow) created_at._creation_orde..

Angular is one of the most popular front-end frameworks. Angular 2 promises to be even more interesting and useful — but it’s also going to be very different from Angular 1. Now that Angular 2 is in beta, what does it look like? Developers are being encouraged to use TypeScript when developing in Angular 2; … Continue reading [Video 458] Kara Erickson and Victor Savkin: Angular 2 updates → The post [Video 458] Kara Erickson and ..

When designing a new software project, one is often faced with a glut of choices about how to structure it. What should the core abstractions be? How should they interact with each other?

PowerShell is essentially a scripting language and shell (command prompt) that you can use on Windows systems. It’s basically Microsoft’s way of getting a powerful UNIX/Linux/Mac-like shell on the Windows platform (long overdue!). The first versions of PowerShell were pretty horrific, but it’s come a long way since then. PowerShell v4 and later is pretty decent (Win10 comes with PowerShell v5). Luckily, PowerShell v4 comes with Windows ..

Most people are probably already aware of this fact, but you can test your Ansible-roles on multiple Ansible versions (e.g. 1.9 and 2.0) with the help of Travis . This is done using environment variables . When multiple environment variables are specified, a build will be run for every variable! You can take advantage of this if you specify each version of Ansible you want to test as a variable: env: - ANSIBLE_VERSION=latest - ANS..

This site has been generated using Pelican 3.3 for over two years - and I finally found some time to upgrade to the current version of Pelican, 3.6.3. This is how I did the upgrade. I decided to be lazy and do the upgrade in-place, instead of creating a new virtualenv and copying the content & settings over. Luckily, this worked out OK , after a bit of fiddling around. I also decided, rather cavalierly, to upgrade all the packages in....

In the style of Michael Chladek , I thought it would be useful to my future-self and others, if I wrote up a summary of installing Arch Linux on Apple MacBook hardware. Of course there are other guides out there, but this one is specific to the needs of someone looking for a minimalist, reproducible, secure, performance oriented installation of Arch Linux. In following this guide, I’ve made some decisions that are entirely based on my ow....

Functional programming is well known for, among other things, treating functions as data, allowing us to store, create, pass, and return them within a program. This has led to all sorts of interesting techniques, most having to do with holding onto functions until we need to use them. Object-oriented programming languages offer us a similar … Continue reading [Video 457] Reginald Braithwaite: First-Class Commands — An unexpectedly fertile..

It has often been said that JavaScript is the assembly language of the Web.

Is your Web application is getting a bit big and bulky on a single server? You might be thinking of moving to a more distributed, microservice-based architecture. And in many cases, that’s a great way to go about things. But microservices aren’t a panacea, having their own issues and pain points. What are the trade-offs … Continue reading [Video 454] Ben Christensen: Don’t Build a Distributed Monolith → The post [Video 454] Ben Chr..
