Python has had async for 10 years – why isn't it more popular?

news.ycombinator.com Unknown 2025-10-20 15:24:57

The Python Documentary dropped this morning. In the middle of the documentary, there’s a dramatic segment about how the transition from Python 2 to 3 divided the community (spoiler alert: it didn’t in the end). The early versions of Python 3 (3.0-3.4) were mostly focused on stability and offering pathways for users moving from 2.7. Along came 3.5 in 2015 with a new feature: async and await keywords for executing coroutines. Ten years and nine releases later, Python 3.14 is weeks away. Whilst

Isolated(any)

Ahh, @isolated(any) . It’s an attribute of contradictions. You might see it a lot, but it’s ok to ignore it. You don’t need to use it, but I think it should be used more. It must always take an argument, but that argument cannot vary. Confusing? Definitely. But we’ll get to it all. To understand why @isolated(any) was introduced, we need to take a look at async functions. let respond To Emergency : () async -> Void This is about as simple a function type as we can get.

I want to ditch my Kindle, but one feature keeps stopping me

Kaitlyn Cimino / Android Authority I love my Kindle, but it isn’t always within arm’s reach. Like a lot of readers, I don’t just use one device; I use whichever one fits my context. I often read on an eReader, but via the Kindle app, I’m also highly likely to finish a chapter on my phone in the grocery store or listen to an epilogue in the car. That’s where Whispersync comes in. Whispersync is the secret sauce that makes Amazon’s Kindle ecosystem work so well together. And no matter how badly

SQLite's documentation about its durability properties is unclear

news.ycombinator.com Andrew Ayer 2025-10-23 17:30:29

One of the most important properties of a database is durability. Durability means that after a transaction commits, you can be confident that, absent catastrophic hardware failure, the changes made by the commit won't be lost. This should remain true even if the operating system crashes or the system loses power soon after the commit. On Linux, and most other Unix operating systems, durability is ensured by calling the fsync system call at the right time. Durability comes at a performance cost

SQLite (with WAL) doesn't do `fsync` on each commit under default settings

SQLite (with WAL) doesn't do `fsync` on each commit under default settings SQLite has a WAL mode (the default is journal mode), but you’re likely using it if you want higher write throughput. SQLite also has a PRAGMA called synchronous which configures how fsync is called. The default is NORMAL . This is what the docs say: [..] but WAL mode does lose durability. A transaction committed in WAL mode with synchronous=NORMAL might roll back following a power loss or system crash. In WAL mode when

Structured (Synchronous) Concurrency

news.ycombinator.com Unknown 2025-11-15 21:02:15

Structured (Synchronous) Concurrency @_fsantanna I have recently learned about Structured Concurrency (SC), which supports nested coroutines with tied lifetimes. There are a number of libraries (Dill, Trio, Effection), and even language mechanisms in Swift and Kotlin. The similarities with Esterel and derived imperative synchronous languages (ISLs) is noteworthy. However, it seems that no bridges between these worlds (ISLs & SC) have been built. Research in ISLs dates back to the early 80s, a
