What I need from migrations is collaboration. When I make a schema migration locally and push it to the repository, then 3 other PRs with their own migrations are being merged before mine, it is very likely that my local database will be in

I wanted to use the LLVM Rust bindings to generate LLVM IR, but I still need to do some more reading on how to represent high-level constructs in such a low-level language. Also, generics and type inference is hard to implement! :p I don&#x

I used the pest[1] library in Rust, it uses something a bit like an EBNF syntax to write the grammar and generate a PEG parser. [1] - https://pest.rs/

I think we should strive for strong type systems with a lot of type inference. I especially like Typescript for that. Type systems are very useful to establish the semantics of your operations. For example `int + int` is not the same operat

In a good documentation, IMHO, you must answer the following questions: - where can I find this functionality? - how is it done? - why is it done this way? You can do a lot with descriptive schemas, take a look at C4 models[1], t

In Kubernetes there is the "Desired State", which is the sum of all resources (your yaml files) and the "Actual State". Whenever a change is requested on the "Desired State", Kubernetes will validate it (using

One advantage of that kind of control is that your code does not depend of the implementation of any abstraction (except the operating system if any?) since everything is written "in stone". I also think it makes a great learning

That's because the Zig approach is "no hidden control flow". Everything in Zig is explicit, this is not a downside, this is a feature of the language. Choose the tool that best fits your needs.

One of the best thing about parser combinators is that I was writing them before knowing what it was. My first programming language being C[1], all you had was functions and composition, it's the natural pattern to write parsers. [1] -

Horde uses a CRDT[1] (Conflict-Free Replicated Data Type) to provide a distributed Supervisor/Registry, this allows you to run an OTP supervision tree only once in your cluster, with automatic takeover. Basically, you run your supervis

Every social place has its own "traditions" if I dare use this term. Twitter is not really a place for debate (more for rants IMHO), but HN is. And not every one wants to debate and that's cool. What I enjoy the most on HN is

I feel more and more than HN comments is not for every one and not for me. If you're not careful with your wording, you'll get flagged and your message will be dismissed and it seems futile to argue against it. This creates an &qu

Let's say you have two 4 bits integer to form an 8 bit decimal number: 1111.1111 is (1 + 2 + 4 + 8) + (1/2 + 1/4 + 1/8 + 1/16)

I never use the square root in games, I always compare squared distances (since the properties are the same). If you try to do with Fixed Point Arithmetic what was intended to be done with Floating Point, you're the problem. A 32 bits

I never said it was easier and I never said ALL game engines. And computing integers IS faster than computing floats, at least on a CPU.

by linkdd 6y ago
In some game engines, Fixed Point Arithmetic is used instead of Floating Point, because it's faster, and the approximation is generally good enough for a game.

Unfortunately no. IIRC, all "RequireComponent" does is allow you to omit the "add(object, B)" when you "add(object, A)". A simple example of this is when you add A to the object, then edit A to require B. The U

This looks great! I'm highly interested about the error handling and testing baked into it. Moving away from the most common shell syntax is a bold move, but not necessarily a bad one, shell scripting needs some fresh air :)

Back in the day, I created my packages manually (creating the TAR archives, the preinstall/postinstall scripts, and putting all of that in an AR archive, renaming it to .deb). I never even read the documentation, I just did: $ file
