retina VS Exercism - Scala Exercises

Yeah, excellent description of why the volume is so high, and when you're tracing a multithreaded one there's the additional noise from the way they're interleaved.

Besides filtering, I forgot to mention that some kind of aggregation/summary. strace flags are useful; even better to write a little program with eBPF (on Linux) or DTrace (on macOS/BSD/Solaris). I like being able to do stuff like this: https://github.com/scottlamb/retina/issues/5#issue-933945792

I suspected exactly that in this issue in one of my libraries, but when I actually looked with strace, I didn't see many syscalls returning EWOULDBLOCK. So then after that measurement, my new theory was that e.g. tokio::net::{Udp,Tcp}Socket would skip actually issuing the syscall if the mio layer hasn't returned availability since the last poll. Not true? Maybe I need to run my experiment again...

I'm plugging my new RTSP library retina into moonfire-nvr. But progress may be slow this week due to family obligations.

When I got my first job as a junior software engineer, my team lead suggested I take a course by MIT, Introduction to Computer Science and Programming Using Python to improve my fundamental knowledge of computer science. The course duration was 9 weeks and I learned a lot of theory about programming and picked up Python syntax. I liked the course and especially the exercises that were presented there. At that time I also discovered an amazing website called Exercism. I thought since I became familiar with the Python syntax and knew how to build simple apps, maybe it would be nice to explore some AI-related stuff. But after playing around with it I realized AI is really not for me. I'm not into analyzing data and everything that goes with it. I was more of an engineering and problem-solving type of developer.

Exercism

Nice, this reminds me of Exercism, which I wish was more widely known since they seem to be good folks. (disclaimer, I donate to them)

Exercism, the free programming learning platform has initiated a challenge named: 48in24.

Last year, Exercism put together the #12in23 challenge. The goal was to learn a new programming language each month throughout the year. I was one of 135 people who completed the challenge, and I learned a lot along the way!

The list of languages contains every language on Exercism, excluding ones that I've used before, web languages, or ones that I can't download for some reason.

Learning by doing, with the help of mentors. Excellent way to learn a next language (as you are already familiar with the programming concepts).

Exercism is pretty good for beginners with some programming language, they are open source and worth contributing to.
