libriscv VS Papercups

Seeking: https://github.com/fwsGonzo/libriscv

This is a C++ RISC-V emulator that focuses on isolating a single process, aka userspace emulation. I am currently working mostly on binary translation, and recently I have made a push to move it from experimental state to fully supported. Another experimental feature is embedding libtcc and using that for binary translation. It is fairly fast to compile, and gives decent speedups. The challenge is what to do now that (perhaps) some low hanging fruits have been picked.

I definitely recommend people to consider the base ISA of RISC-V if they want to try to implement a CPU or even full-system emulation. I understand that implementing a GameBoy emulator might be more attractive because you are working towards something graphical, but you can definitely get something similar with RISC-V, eg. Doom (SDL example: https://github.com/fwsGonzo/libriscv/tree/master/examples/do...)

This is the example project: https://github.com/fwsGonzo/libriscv/tree/master/examples/msvc

Pretty much two days of work: https://github.com/fwsGonzo/libriscv/commits/master

There is a doom emulation demo here now: https://github.com/fwsGonzo/libriscv/tree/master/emulator/do...

You will need to add the shareware doom1.wad yourself. :)

The best language for the task at hand, when presented with time constraints, is the one that you already know well. OP said in the article that they authored Papercups [1]. Adopting Elixir for a websocket-push service makes a lot of sense, then. However, why don't you learn Elixir, some OTP, and then reconsider that question? You could be missing out.

Phoneix - Elixir

We're a live message tool and it is basically what Elixir is built for https://github.com/papercups-io/papercups.

The Elixir community has been great and incredibly friendly. I originally was worried about the size of the community but that hasn't been an issue the community has been super helpful. I also think the annual stackoverflow usage surveys are very misleading because most of the community's questions get asked in ElixirForum and not on Stackoverflow.

Phoneix is the web framework of Elixir which is very similar to Rails but minus a lot of the magic has been very helpful for our productivity as well.

If I had to built another service that is websocket heavy I would definitely use Elixir. Even if it was a standard crud app I would still most likely choose Elixir.
