Since the advent of ChatGPT, and later by using LLMs that operate locally, I have made extensive use of this new technology. The goal is to accelerate my ability to write code, but that’s not the only purpose. There’s also the intent to not waste mental energy on aspects of programming that are not worth the effort.

[...] Current LLMs will not take us beyond the paths of knowledge, but if we want to tackle a topic we do not know well, they can often lift us from our absolute ignorance to the point where we know enough to move forward on our own.

After three decades of working with software, I’m also seeing myself learning faster using ChatGPT. So apparently it works even for us more seasoned programmers.

For Redis 4.2 I’m moving Disque as a Redis module. To do this, Redis modules are getting a fully featured Cluster API. This means that it will be possible, for instance, to write a Redis module that orchestrates N Redis masters, using Raft or any other consensus algorithm, as a single distributed system. This will allow to also model strong guarantees easily.

I think that what’s particularly hard with C is not the details about pointers, automatic memory management, and so forth, but the fact that C is at the same time so low level and so flexible. So basically if you want to create a large project in C you have to build a number of intermediate layers (otherwise the code will be a complete mess full of bugs and 10 times bigger than required). This continue design exercise of creating additional layers is the hard part about C. You have to get very good at understanding when to write a function or not, when to create a layer of abstraction, and when it’s worth to generalize or when it is an overkill.
