theBeamBook VS Exercism - Scala Exercises

It's my understanding the state of the art in observing JVM-based applications is a combination of using thread dumps, gc logs, thread activity visualizations. Thread dumps give us a snapshot of the the name of the thread, its current running state (waiting, blocked, etc), and the stacktrace of the work its currently doing. GC logs give you a record of when and how much garbage was collected and Thread activity visualizations show you the timeline of thread moving between different running states.

The BEAM gives you the ability to see the bottlenecks in your system, via the REPL (in real time!)

It has world-class introspection built in that gives you the power to observe and manipulate your running application through a REPL.

The BEAM has hundreds of features like this, because the BEAM is more of an OS than and VM.

I get it, you're a JVM expert, but the BEAM is more than a check list of optimizations that on paper the JVM can do.

I strongly suggest, before the next time you comment on an BEAM VM vs.JVM debate, please consider watching https://www.youtube.com/watch?v=JvBT4XBdoUE, "The Soul of Erlang and Elixir • Sasa Juric • GOTO 2019"

and reading https://github.com/happi/theBeamBook " an attempt to document the internals of the Erlang runtime system and the Erlang virtual machine known as the BEAM."

Best of luck!

it does. values are immutable in the BEAM, not at language level.

The impact of bugs is minimized by compartmentalization. This is done from the lowest level where each data structure is separate and immutable [1]

But you can simulate mutability with stateful processes.

On a side-note, if you're really interested in grokking the BEAM itself, https://github.com/happi/theBeamBook is a very good resource that delves deeper into the internal working of BEAM. Regardless of whether you use it, it's a fun read!

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.
