Jujutsu (jj), a new version control system written in Rust, has popped up on my radar a few times over the past year. Looked interesting based on a cursory look, but being actually pretty satisfied with Git, and not having major problems with it, I haven’t checked it out. That is, until last week, when I finally decided to give it a go! I dived into a couple blog posts for a few of hours, and surprisingly (noting that we’re talking about a VCS) I found myself enjoying it a lot, seeing the consistent design, and overall simplicity it managed to achieve....

Everybody has heard about the latest cool thing™, which is DALL·E 2 (henceforth called Dall-e). A few months ago, when the first previews started, it was basically everywhere. Now, a few weeks ago, the floodgates have been opened and lots of people on the waitlist got access - that group included me. I’ve spent a day playing around with it, learned some basics (like the fact that adding “artstation” to the end of your phrase automatically makes the output much better…), and generated a bunch of (even a few nice-looking) images....

Introduction With the advent of distributed applications, we see new storage solutions emerging constantly. They include, but are not limited to, Cassandra, Redis, CockroachDB, Consul or RethinkDB. Most of you probably use one, or more, of them. They seem to be really complex systems, because they actually are. This can’t be denied. But it’s pretty easy to write a simple, one value database, featuring high availability. You probably wouldn’t use anything near this in production, but it should be a fruitful learning experience for you nevertheless....

Practical Golang: Getting started with NATS and related patterns Introduction Microservices… the never disappearing buzzword of our times. They promise a lot, but can be slow or complicated if not implemented correctly. One of the main challenges when developing and using a microservice-based architecture is getting the communication right. Many will ask, why not REST? As I did at some point. Many will actually use it. But the truth is that it leads to tighter coupling, and is synchronous....

Introduction Most apps we make need a means of communication. We usually use JSON, or just plain text. JSON has got especially popular because of the rise of Node.js. The truth though, is, that JSON isn’t really a fast format. The marshaller in Go also isn’t that fast. That’s why in this article we’ll learn how to use google protocol buffers. They are in fact very easy to use, and are much faster than JSON....
