Snapchat also maintains Djinni, used to generate type-safe bindings for C++ code. With Valdi, it seems like they chose to go another route.

I hear this and it makes sense but when I actually go about implementing it, it quickly falls apart.

Most apps are UI, remote requests and maybe some storage. What do you put in the common core? Android does HTTP requests one way. iOS does them another way. You go for the lowest common denominator an implement a third way, using libcurl or something?

Or do you just put business logic in the common core? Is there really that much business logic that doesn't issue requests or access a database?

Excellent Points, this is where the answer is "it depends".

If it's really functionality that cannot reasonable be shared don't share it.

It's probably more work to maintain bindings to a single API client in the core and fiddle with all the details of not using the native HTTP client implementations that it is to implement the API client twice.

Writing the API client twice is boring, but that's a good thing.

The shared core is optional. You might have the need for it, then it's a good solution.

For an app like snapchat you'd probably share the video effects and have that in your core library.

That's perfectly reasonable but, at that point, the argument becomes: build 95% natively and maybe there's a 5% "core" that warrants extracting into a common lib. Technically? That's excellent architecture. In terms of saving development time — which is where stuff like React Native comes in? Not so much.

There's an accompanying blog post at https://zserge.com/posts/fenster/

This author has some pretty cool stuff, like a tiny alternative to Firebase https://zserge.com/posts/pennybase/

There is at least two bugs in the blog post, here:

Next simple task would be to fill the complete framebuffer with a solid colour:

    memset(f->buf, rgb, f->width*f->height*sizeoof(uint32_t));

The first is the obvious typo around `sizeof`, which I didn't even see at first (edit: this).

The second is that code will only work for 8-bit colors, i.e. only the 8 (technically CHAR_BIT, "a byte") least-significant bits of `rgb` will be used. This is a quirk of the `memset()` standard C function, which has the prototype:

    void *memset(void s[.n], int c, size_t n);

but then the man page [1] says:

The memset() function fills the first n bytes of the memory area pointed to by s with the constant byte c.

It will fill the screen with any of 256 shades of grey, for which r == g == b.

Neato! It's nice to find zserge around. He built upon the idea of my static site generator Zas [0] to create his own zs [1][2] a few years ago. I think he's still using it :)

No. This is a trend. HN is a tech and startups website so it will show trends. At one point it was VR, eventually it was Web 3.0. Right now it's LLMs but this too will pass and something else will come along.

Homebrew was kind of slow, at one point, but I find that it works pretty well these days. Still, this is pretty cool and competitions is always good.

Interestingly, I always imagined that a would-be replacement would come written in Swift. I guess I was wrong.

Looks similar to Clasp but implements Clojure instead of Common Lisp.

https://clasp-developers.github.io/

Clasp is really cool but it’s a shame that it does not support Windows properly. A lot of C++ is used on Windows. I’ve seen this pattern repeated elsewhere — I think it has to do with Windows exception handling being different and complicated. Hopefully jank does not suffer the same fate, since author is a gamedev!

The Jank creator talking with folks at CERN about integrating with their C++ codebase makes sense too. Clasp was originally used to do some molecular simulation if memory recalls.

Good point. When Clojure first came out it was questioned whether it's a lisp at all, but now I commonly hear many say it is the best Lisp.

Cool. I tried to build Clasp from source a long while ago, and failed. Now a brew install….

Is this it?

No that is a webserver that AOL bought. It used TCL but also threads.

Wild seeing "19 years ago" as the last commit time.

Can’t be the same thing GP is talking about as the repo says it’s multithreaded and the poster said what they worked on wasn’t

Might have been updated later on.

How does one get into the investment business?

The comment you're replying to laid it out pretty clearly if you want to be a part of a hedge fund (as I interpret your question.) Know friends and family with money (a lot, hopefully) or, more commonly, have institutional connections. Have at least some connections and experience in finance/banking/investing (at a large scale, not small-fry stuff). Bring the two together with a lot of marketing and promises.

If you want to work in IB, then you basically need to go to a feeder school or have connections. The investment business is a lot of "look, we have the smartest people in the room to handle your money, trust us." They rely, like consulting, on selling the prestige of their employees education and social capital. You will sign on to working absurd hours, with the promise of making a lot of $$$ if you can survive (literally, a guy died this year at BofA).

Working in IB isn't related at all to actually making investments / trading though.

If you want to trade your best bet is apply for roles at prop shops and funds and avoid banks entirely

Internship at a fund/CTA/market maker/wholesale bank. If older, go in through an ops position. Don't spend time at a retail bank.

It depends what you want to do. Portfolio manager and quant research roles are rare and highly competitive but other roles in risk, ops or compliance are more common. It's an insiders market for sure.

Thanks, I thought I was going insane a little bit there :-)
