Seven at once? A gold mine!
I love how easy it is to follow your coding. The way you write programs, by sketching them out and then filling in the required parts, really appeals to me.
That's awesome, JIT is just in the corner xD
I will shamelessly(fully?) copy your path and code along because I've been meaning to study this topic. Thanks!
I'm currently reading the books "Writing an interpreter in Go" and "Writing a Compiler in Go" by Thorsten Ball, these videos are perfect timing :D

Wew, I am reading same book!
I was kinda disappointed that there's not been a new video out for a while considering you've been working on Serenity full-time now, but then you come along and bless us with 7 videos. I know what I'm going to be doing at nights all week! Really appreciate all this content, I have learned so, so much from these... These are really perfect for when you're in that intermediate phase where you're comfortable with programming and C++, but are still trying to get your head around how to architect complex projects like this. Thanks for not staging these videos out one per week and just letting us have all of it 😁
One of my biggest problems when programming is overthinking and wasting time on re-analyzing the implementation. Watching your videos and seeing how you avoid this countless times has helped me so much :)
Great video! There was a weird black screen for a moment at around 1:04:30 and again at 1:18:10
i am too stupid to understand all of this...yesterday I had my interview(i got selected btw ) they asked which open source project you like the most I said serenity they asked me about serenity ....like what is serenity ...and then what is POSIX compliant means .... and thanks just because of your videos i was able to answer them properly

I started making an interpreted language at about the same time you started working on Serenity's Javascript engine. I've been meaning to implement a bytecode interpreter ever since, and even started working on it a few months ago, but felt like it was more work than it was worth, since the slow part of my interpreter was not the tree-walking, but other things, like my very bad GC, etc. I recently made some large improvements to how we handle temporaries in my interpreter (just standard things, like putting temporaries, some of them unboxed, on a software stack, optimizing the function call convention around it, etc), and was ready to give outputting bytecode a second go... but aw man, you beat me to it
Honestly , ive seen great engineers out there , but the way you sketch that code is awesome. Easy to follow, work on it, and contribute to. Complex topics gets down so that even beginners love and understand , Well done mr. Senerity OS
Im so Hype for this series.
Andreas, this is amazing! This playlist should be required watching at the start of every CS degree.
I love this format where you start a new thing from scratch! Most of the videos are about improving the existing stuff, please do more of this sort of streams where you start something completely new and build it piece by piece :)
Woah, seven videos! I know what I'll be watching for the next 6 videos. Tack Andreas!
7:15 Oooh, you just made RISC-V! 8:15 With the same register names!
Good job man! Will be interesting to see some performance benchmarks

I've realized you make talking about code fun. Most coding channels try too much entertain.
thank you for this, ive learned so much :D
as a programmer, worth it for watching every vids in playlist
We should say thank you Norway for inventing object oriented programming! Hipp, hipp HURRAAA!!!
Very interesting and useful..
Curious to see how you like the Op:Add::execute, Op:Load::execute, Op:Add::to_string, Op:Load::to_string() with the switch. Having worked on stuff like this, that usually gets tedious to manage and I just end up instantiating the object and calling the methods, making adding new ops a bit more self contained and less disruptive. Nicely done!
Hi Andreas, I'm usually watching your videos in my living room with a subwoofer connected and the microphone picks up a low frequency rumble when you type on the keyboard. Can't see what microphone you have but sometimes they have a hi-pass switch to remove this kind of thing. Another suggestion is to remove any physical connection between the keyboard and the microphone, maybe the mic is mounted on the desk? Thirdly, I looked into hi-pass filtering in OBS but equalization seems a weirdly omitted feature.. It can be done with VST plugins but it seems unnecessarily complex, especially on linux.
I'm more of a C guy, and this OOP stuff confuses me, but thank you for the content.
thank you based Andreas Kling
There goes the week ... Watching videos now.
I want to be a god like this one day
code master, who builds a task in his head and writes it on the fly,
Nice.
Holy crap
You can switch between recent tabs in the editor with Ctrl + Tab. Think you know this but just in case you didn't :^)
0:47 ok, but what is that "js" command? is it something your wrote yourself? do you have it posted somewhere? what did you use to generate that abstract tree? Do I have to build SerenityOS form source?
You can see Git errors in CLion by enabling VCS console, links to your PRs will be there too
When will serenty be able to compile itself? It would be very cool to be able to work on itself
7 updates at once ... well, I guess I know what I am doing for the next 8 hours or so ... I have always wanted to learn more about ByteCode VM in general, a Javascript one is a perfect example.
What is the `Badge`? The code doesn't have any comments and couldn't find a relevant commit message either

hello Andreas
I can see a lot of problems with the current architecture, like most (if not all) registers will only be used once, which will increase memory.

You gotta address the "File does not belong to any project target; code insight features might not work properly."! It's killing me!
Was excited till I saw all the OOP
tfw he just started and brain is full of question marks 😫
I've started watching this series and are only at 50 minutes, but I get an immediate question in my head: why no research into the Java bytecode and its instructionset? Or is there a reason you don't try to be compatible with it?

I don't understand why being compatible with the bytecode of a random unrelated language VM would be useful :)
