Web dev context here. Just from the top of my head: django-constace breaks storage format with no built-in no downtime transition, django-modeltranslations, want to add translations to a heavily used field and you are using a database witho

> Auth is a solved problem It is solved until you have to integrate with third party home grown implementations and providers that implement the specs except for a little bit of behavior that is not in the spec.

Well if your working set fits RAM your tables will be stored in memory in the shared buffers.

Some people use the ORM models as pure persistence models. They just define how data is persisted. Business models are defined elsewhere. I think makes sense when you application grows larger. Domains become more complex and eventually how

How much time did the PyAST_mod2obj actually take? The rewritte is 16x faster but the article doesn't make it clear if most of the speedup came from switching to the ruff parser (specially because it puts the GC overhead at only 35% of

I'll be blunt, having experienced the damage caused by DRF Model* accelerators in mid sized codebases I just hate it. CRUD stops being CRUD quickly, these CRUD accelerators just intruduce more non linearity into the development. Its ea

If a government is small does it have enough power to impose the rule of law and be an economic and social moderator ?

Congrats to the team. I think it is particularly impressive (and a bit scary) that DDL changes are also synchronized to the clients automatically!

They are not polyfills. Multiple scheduling modes are provided for libraries that are not thread safe (it's a total mess and I avoid these wrappers like the plague)

Is this resource up to date? ALTER TABLE ADD FOREIGN KEY NOT VALID (PARENT) shows a stronger lock than ALTER TABLE ADD FOREIGN KEY (PARENT) while the PG docs says that the locks should be the same.

Isn't a Pareto optimal solution always at the edge of the feasible space?

Should this be the take away? It looks to me that people are building pipelines without taking into account that they change roles every time they have to build a package, from a package consumer to a package packager. Even if the package d

If you need to buy into the async ecosystem for some special reason my recomendation is to: - pick a mature ASGI server - pick a framework and libraries that have been designed from the start with async in mind. Be suspicious of libraries t

Look at the intended semantics [1], and then read the implementation [2]. Can you figure out if the implementation is correct? Can you infer the possible limitations of the approach at glance? Can your async library actually handle being ca

I'll have zero trust running async Django until all sync_to_async and async_to_sync calls are removed from the code base.

In my current codebase there is a lot more overriding going on than simply implementing the retrieve/list/etc... methods. On a quick review I found overrides for: - get_object - get_serializer_class - perform_create - get_queryset

I read the article and I'm left scratching my head why this advice doesn't apply to DRF. The DRF Generic ViewSets and Views provide maximum magic plus they also shift part of the creation process into Model Serializers. Doing anyt

Scala is probably not a good example because if you need some quick and dirty printing you can override toString and keep the rest of the generic code intact. In OCaml, Rust and Haskell you would have to add type constraints in a bunch of p

For these 64-bit index entries we’d expect to have to scan roughly: index_row_size⋅rows=2⋅64bit⋅10^5=1.5MiB Where do the 10^5 rows come from? With a composite index and a point query doesn't the database scan just the 100 ret
