Instrument your python code and gather metrics. Maybe use a profiler. If it is heavily CPU limited and it spends all time in python interpreter calls it might benefit from moving to a more efficient language. It it’s mostly waiting on IO (e

Eclipse and Apache are foundations. And while those foundations host a set of Java projects, they are not limited to it.

Since Visual Studio Code is using ripgrep for search one can also open the repo in the editor and use find in files to search for such things similar performance. It’s one of my favorite tools for searching specific expressions in codebases

I had the same opinion in the past. But after some more years of work experience - mostly in the managed services area - I don't think it's that clear anymore: - If you offer your users a library, you are competing with tons of op

It sounds like it, but it still doesn't make sense to me. A scammer would want to be anonymous so they can't be prosecuted. But a warehouse owner would be well known.

As the person who proposed this feature - among lots of other ones for async Rust, like run-to-completion async functions ( https://github.com/Matthias247/rfcs/blob/e7fd7042f8069e9126e... ), structured concurre

This certainly sounds like your company is having a gap. But the gap sounds to me more like the lack of technical leadership (a strong lead, principal engineer, etc) than a PM. 10 out of 10 PMs I worked with (and it had been more) wouldn&#x

If you would measure pure latency between a single request (HTTP, RPC, whatever), the latency difference between any async or non async implementation should be microseconds at most and never milliseconds. If its more, then something with t

by Matthias247 3y ago
Sure. But those async functions can't do any IO. If you need to use IO functions (e.g. from tokio), then you would still need to import that framework.

by Matthias247 3y ago
That's assuming no concurrency, which isn't applicable. Every public CDN will have around 10ms latency per request (because it takes time to load data from disk, fetch from upstream servers, apply WAF rules, etc). But they still h

It is much cheaper. A server can easily handle hundreds to thousands of simultaneous streams. Even if the server is requiring 1kW of power for that, it makes a worst case of 10W per client. Maybe double it if you want to count in the datace

I assume you mean "spawned futures" - because regular Futures obviously don't have to be 'static. You can run as many of them as you want on a single task by using Future combinators like join/select. If this is mos

What difference would it make? Any "real engineer" (of whatever you definition you might have of that) will also find themselves being in a shitty position in this situation, which is somewhere between getting fired, voluntarily l

Given async file IO in Rust without io_uring (and without being on Linux) means "dispatch work onto a background thread pool", it's essentially the same. It's just using a different programming model - which you might ei

The last comment is actually pretty interesting and spot on. In the Java/JDK world - which you can assume as a „framework“ - you can cancel blocking IO via the Thread.interrupt() mechanism. And that works because it’s deeply integrated

by Matthias247 3y ago
You can cancel socket operations using signals. You can eg have one or more background threads running timers which will interrupt the blocking IO if it doesn’t return in a timely manner. A lot of very important frameworks and services that

I don't have any opinion on Bun itself. But as someone who is pretty experienced in running large scale services, I wouldn't have a problem to use a tool that is marked as stable but internally built on top of unstable tools. As l

those comparisons to Nginx are not fair. The latter does also do things like loading a configuration per connection and request, processing timeouts, preparing logs and potentially other things.

The article looks great! I like that it explains both classic IO for a webserver (which helps since a lot of developers don't even know that read() and write() might return without all data being processed) and then proceeds from non-b

It generally applies to eventloops, not just to lanugages with a builtin event loop. E.g. it certainly also applies to raw boost::asio which uses callbacks, libuv, libevent, QT, GObject, Netty, etc.

This seems really poor. They should have been able to see what customers are still using the service in that region, send them additional reminders that they need to get off, and only after several of those and a grace period remove access.

only if the resources are just used within this task. If an async function at some point in time generates another task (or even spawns a thread!) that can not be synchronously cancelled then it might outlive the destructor and thereby the
