Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

My Rust program (Well, game) is leaking memory, 4MB/s.
I've found bytehound helpful for tracking memory leaks: https://github.com/koute/bytehound
-
Show HN: I wrote a tool in Rust for tracking all allocations in a Linux process
Interesting approach. How is performance compared to something like https://github.com/koute/bytehound
-
Introducing alloc-track: Precise memory profiling by stack trace and thread.
https://github.com/koute/bytehound is another tool in this space to be aware of
- Out of the loop: WASM for non-web projects
- Which gui crate would you suggest for a simple program?
-
Implementing a C++ memory allocator to track our framework memory usage
If you're on Linux (and since you're considering using Valgrind then you must be) you could use something like my Bytehound; you can also script its analysis, so if you'd be interested in e.g. figuring out which libraries allocate how much you can also do that.
Ot sure if it will fit your needs but maybe bytehound is worth looking into.

Memory leak in a long running process.
I had a great success recently with https://github.com/koute/bytehound/issues/86
- Hi, I’m new in rust, I have some expirience with c# and its classes ans structs. I can’t find information about that is happend with struct in rust when I pass it to function argument. Are there some copy effect ?
-
Does rust have a visual analysis tool for memory and performance like pprof of golang?
For memory you can also try Bytehound, which is a memory profiler I wrote a while back. It's not technically Rust-specific, although it is written in Rust and has Rust-specific features like automatic Rust symbol demangling.

There are two main libraries that people use to write clients Confluent Kafka and segment io kafka

Getting sum type values from a map
As my first "real world" (ish) project in Vlang, I'm trying to copy https://github.com/confluentinc/confluent-kafka-go, which is a Go wrapper for Kafka C client library, https://github.com/edenhill/librdkafka
-
Fix it, Fork it, Fuck off
You are right, but in practice that's not what happens. Companies do not rely on open source libraries, the developers working for such companies do.
I can give you a realistic example. If you want to use Kafka and Go, your probably only option is to use https://github.com/confluentinc/confluent-kafka-go. Its LICENSE explicitly says "no warranty". Now, what if I find a bug in the library? Only two realistic solutions from my side:
1. I submit the issue and hope for the maintainers to fix it
2. I dig deeper and try to fix the issue. I submit the PR
None of the above scenarios are guaranteed to have a happy ending. The issue could be ignored, or piled up among thousand of other (maybe higher prio) issues. My solution may not be optimal and could be rejected (or if it's optimal, nobody is taking a look at it, and it could remain open for weeks/months).
> If that is a problem for you, negotiate a different contract up front - with the maintainer or someone else willing to do the work. That probably means paying them.
In the real world that would mean that I go to my manager and asks them to pay money to the maintainers of confluent-kafka-go to fix the issue I found. I don't think my manager would approve that, but let's imagine he does. The guys at confluent-kafka-go may not want money to fix the issue. These guys have probably already jobs that pay them well, and they work on the library at will.
Note: I'm talking about confluent-kafka-go, which I know is behind the Confluent software company. But I could as well be talking about libraries maintained by individuals like https://github.com/edenhill/librdkafka

What are Golang competitors in 2022 when it comes to one-file binary deployment?
it can be completely statically linked binaries. example: https://github.com/confluentinc/confluent-kafka-go/blob/db57ef6235/kafka/librdkafka_vendor/README.md

Benthos - Fancy stream processing made operationally mundane
If you find the kafka input slow, try kafka_franz. It might be a bit faster, since it’s based on https://github.com/twmb/franz-go. The kafka one is based on https://github.com/Shopify/sarama. You can also write a custom input based on https://github.com/confluentinc/confluent-kafka-go, but this library relies on CGo, which can be annoying.

Hunting down a C memory leak in a Go program
So, in the interests of full transparency - we at Zendesk are actually running a fork of confluent-kafka-go, which I forked to add, amongst other things, context support: https://github.com/confluentinc/confluent-kafka-go/pull/626
This bug actually happened because I mis-merged upstream into our fork and missed an important call to rd_kafka_poll_set_consumer: https://github.com/zendesk/confluent-kafka-go/commit/6e2d889...

Is segmentio/kafka-go production ready ?
I'd suggest https://github.com/confluentinc/confluent-kafka-go we switched from sarama-cluster with minimal work and it works fine. And we process approx 1.2M messages per hour.
You should give confluent-kafka-go a try. It has a sync producer and is super fast. Have been using from quite a few years now.
