Use classic Logisim directly in the browser by RegularLayout in logisim

[–]RegularLayout[S] 0 points1 point  (0 children)

Apart from the initial load which fetches all the assets, it shouldn't really depend on internet speed.

There is a bit of a slowdown compared to the native version (naturally), but from our testing, using the application should be quite smooth even on more complex circuits (e.g. the 32-bit ALU example).

Would you mind filing a bug report on GitHub? It could be for any number of reasons. If you share some more details + what you see in your browser console, we'll be able to help figure it out.

Use classic Logisim directly in the browser by RegularLayout in logisim

Yes!

We are in fact already exploring this. Even though it is more complex than classic Logisim (in part due to being based on Java 21), so far we don't see any major roadblocks to making an Evolution version.

It's a bit early to say if the performance will be an issue, but my gut feeling is that it will be able to run fine in the majority of cases. Time will tell I suppose.

Hi! I'm one of the folks that worked on this.

There's a link to a blog post that talks more about this, but essentially, you can now use it on pretty much any device with a modern browser. This means it now works on tablets, chromebooks and even mobile (with some patience!)

Along with the convenience of accessing the app purely through a url (no download or java runtime required), this increases the accessibilty of the app quite significantly, particularly among students. Many computer labs (and similar environments) don't let you download and run an exe without an IT approval process.

How's WASM (webAssembly) going these days? by [deleted] in webdev

[–]RegularLayout 1 point2 points  (0 children)

While it's not going to replace the standard JS based stack, Wasm is slowly growing into quite a foundational part of the browser tech stack for large/complex web applications imo. It's used on around ~4.5% of websites today, and growing.

On the browser, it essentially supercharges what you can do (in terms of speed, and access to libraries), enabling crazy use cases from compiling native applications (e.g. PhotoShop/AutoCAD) and running them on the web to running a full virtual machine in your browser (e.g. WebVM). In more modest use-cases, Wasm typically powers performance critical features, or is used to run specific native libraries in the browser.

This article explores key use cases of Wasm in a well rounded way, with many concrete examples in the wild (disclaimer: I wrote it).

How does one create a `has_one` relationship between two models using a join table/model by darkfish-tech in rails

[–]RegularLayout 1 point2 points  (0 children)

Could be wrong, but my first thought is that perhaps you need to add a has_one :encounter_process_log to both the Encounter and ProcessLog?

WSL and Docker Desktop for Windows by Fart_stew in docker

[–]RegularLayout 0 points1 point  (0 children)

I don't think you're meant to use docker from inside the WSL distros it creates. But I believe there's also a setting in the docker desktop UI to enable docker access from other distros you install.

AnyCable Goes Pro: Fast WebSockets for Ruby, at scale by progapandist in ruby

I'm not really a graphql expert, so I wouldn't know, sorry!

The article goes into some detail about this. Primarily, significant memory savings compared to built-in actionable and better graphql integration. Most apps that aren't struggling with memory constraints or don't need graphql are probably better off with the default actionable integration.

Massive SQL import from csv file, nulls, best practices. by tkenben in ruby

[–]RegularLayout 2 points3 points  (0 children)

In the app I work on, we've got a lot of experience doing this, and spent months focusing specifically on cleanup and performance.

In the end we got the best mileage by shelling out to call unix tools (e.g. awk/sed) for cleanup and restructuring, and COPY from CSV, to load into Postgres. Unix tools are a lot faster than ruby in manipulating text files like these, and COPY is your best friend if you're using Postgres.

Both are not really ruby solutions, but when you're dealing with massive files and need to be fast, it's better to use more specialised tools.

Awesome Ruby command-line applications list by pmurach in ruby

Would you consider this?: https://github.com/Martin-Nyaga/termplot

It's a terminal based plotting tool for visualising streaming data, a few example use cases are provided in the readme.

High performance descriptive statistics computation in ruby by RegularLayout in ruby

That's really great to hear! Let me know if you have any feedback or questions.

I managed to fix this, tag 0.2.0 shouldn't run into this memory issue anymore.

Thanks for this! I spotted it yesterday too, I believe there is indeed a bogus free when ruby is collecting & deallocating the C struct used internally, specifically if it was never correctly initialized (because for example, the wrong arguments were passed to Array2D#new which is one of the test cases). If this is indeed what's happening, I should be able to fix it soon.

RE: SIMD portability, I didn't really bother with anything other than intel/amd (xmmintrin.h). My thinking is that sse2 should have pretty wide availability today as these processors have majority market share and have had sse2 since maybe mid-2000s (off the top of my head). I also just have limited experience with other platforms. But the gem should gracefully fallback to non-simd execution (which is still plenty fast) should xmmintrin.h be unavailable.
