• Ask HN: Has anyone _fully_ embraced an event-driven architecture?
  news.ycombinator.com | 2021-08-02

  Yes, I made my own open-source event driven platform: http://github.com/tinspin (rupy is the foundation and fuse is an example implementation tested with 350.000 users and 5 years uptime)

  The learnings where 2-fold:

  1) You need async-to-async capable clients so that you use (potentially) 4 threads on each browser server database roundtrip.

  Since most databases don't have async capable clients I wrote my own database too: http://root.rupy.se

  2) You should use a VM + GC language so that you can use atomic shared memory between cores. This part is very hard to prove in theory, but in practice I'm baffled by how well Java performs, you can find three quotes that I managed find here: https://github.com/tinspin/rupy/wiki

  Finally getting threads to cooporate on things is hard and you cannot debug it with any tools, instead you have to use "trial and error" until is sort of works all the time.

  > it's compact enough that you should be able to learn everything in about an hour.

  Yup, I learned everything I need to know about this project in 5 minutes:

  I hope you're successful in your Minecraft replacement, as I've enjoyed playing with some of the hobby projects it inspired

  Nope, the source code is linked and it's compact enough that you should be able to learn everything in about an hour.

  But here is the only documentation I have written so far:

  I also made my own cloud service both with my own hardware and on top of GCP:

  I made my own HTTP app. server and distributed JSON database: https://github.com/tinspin/rupy

  On top of this I have made many projects and I still use all of them today even 10 years later, some favourite:

  I used to use the activation.jar from JavaMail for Mime in my app. server, then I realized Mime is pretty simple and replaced it with this file: https://github.com/tinspin/rupy/blob/master/mime.txt

• “Is Parallel Programming Hard, and, If So, What Can You Do About It?” v2 Is Out

  The things you said in your comment above are untrue for very fundamental reasons. This isn't a judgement call of the best techniques based github histories.

  > I minted Joint Parallel and gave the definition!

  That means it's nonsense. It is an oxymoron, it contradicts itself. Parallelism by definition is about separation of dependencies and synchronization. Join implies the exact opposite. That's like saying Bright Black while telling people you invented a new color space. It is a hiccup to being taken seriously (to put it mildly).

  You have said stuff like 'java doesn't crash (usually)' and that multi-threading rendering adds at least 10 frames of latency to a game. Statements like these are not just incorrect, they indicated a lack of understanding by thinking mostly orthogonal concepts are somehow at the mercy of each other.

  I looked at your link. The first file I opened says "non-blocking and asynchronous" in the first line of the comment.

  https://github.com/tinspin/rupy/blob/master/src/se/rupy/http...

  Your methods that are supposedly doing this use the synchronize keyword whose purpose is to "block (suspend execution)" of other threads that call the same method until the first thread is done.

• Why asynchronous Rust doesn't work
  news.ycombinator.com | 2021-03-09

  Well I don't know the details, but if you read my comment below you'll see that there might be a good reason to use a complex memory model VM with GC.

  I can't explain it, just claim that my code works and performs accordingly: https://github.com/tinspin/rupy
