To spawn a sync function from an async context you use https://docs.rs/tokio/1.3.0/tokio/task/fn.spawn_blocking.htm... .

Thanks for the kind words! > What's the performance impact of dependency inference on `pants dependencies`? There are two components to inferring dependencies: 1) Extracting dependencies from the code being built (in Python this mea

Hey folks! As mentioned in the post: file level dependency inference allows for dependency lists that are 30% smaller (improving cache hit rates), even while removing 90% of boilerplate from `BUILD` files. Happy to answer any questions!

Hey folks! We'd love to answer any questions you might have, here or in Slack (linked from the post.) In particular, it's worth noting that 2.0.0 is a ground-up overhaul of Pants with a Rust core (but that wouldn't quite fit

Great post. A point that neither this article nor the recent ninja retrospective ( http://neugierig.org/software/blog/2020/05/ninja.html ) touch on though is that hashing of files is an important step if y

There isn't, but that's a good idea. At a very high level, the v2 engine is "Skyframe but using async Rust". All filesystem access, snapshotting, UI, and networking is in Rust, and we use the Bazel remote execution API t

Great experience report: thank you! Wanted to point out that the Pants project has been focusing on widening that happy path recently (...by narrowing its focus to Python-only in the short term), and is ramping up to ship a 2.0. This page c

Can use `impl Trait` I think? ``` fn foo(s: impl AsRef<str>) ```

I think that that makes it fairly similar to Rust's approach then... compiler support for suspension, and cooperative scheduling.

The thing that makes it safe to use mutation in the context of a transient is that you can know with certainty that you have exclusive access to the value (because no other viewer has observed it yet). This is also what borrow checking can

by stuhood 7y ago
Borrow checking allows even structures that support mutation to be safely (checked by the compiler) treated as immutable, and thus as values. Clojure also recognizes the connection between ownership and mutability in its "transients&

by stuhood 7y ago
Immutability is very helpful, and the connection between values and identity is illuminating. But there have been very important developments in programming languages since this post/page was written: notably, the introduction of &quot

This is a really interesting thought. In the presence of must-use types, you'd imagine that types with side effecting Drop impls (like files), would want to migrate to eventually being used/consumed by a "close" method.

Twitter is not moving away from Scala. And the internal adoption of Java 8 has not had an appreciable impact on the growth of the Scala codebase.

Twitter is not moving away from Scala. Scala continues to grow at a faster rate internally then any other language, and is ~50% of Twitter's backend codebase.

There is little-to-no actor composition in this post, except that which is hidden by the framework that they've implementated... instead, it describes using the methods of an interface to communicate between your implementation, and th

When you look at how the composibility of Futures/Promises make both sideffecting and transformation tasks like monitoring completely trivial, it becomes really hard to accept the actor model as a reasonable choice.

Ah, sorry. Even the article I linked is potentially stale. Things seem to be moving quickly. The "near majority" statement was based on unconfirmed reports that another large pool has hopped onboard: https://twitter.com

In scala, the body of a match expression is a PartialFunction, and PartialFunctions compose similarly.
