anyone using Alpaca for long term investing?
Is there anyone using Alpaca for long term and passive investing? I am neither a US nor Europe residence, so it is pretty hard to find a decent broker. I came across alpaca.market https://alpaca.markets/ and noticed that there is zero comission for buying and selling stocks. I know that it has pretty good API especially for developers and day traders, but i am particularly interested in long term passive investing, and not interesting in day trading at all. Is it goog for long term passive investing (buying and holding etfs)?

ChatGPT is going to revolutionize the stock market
No worries at all! https://alpaca.markets/ is another route for market data. Real time data is cheaper but it is lacking technical analysis. We used to use it and it's pretty good.

Ask HN: How Safe Is Alpaca?
I have been looking at https://alpaca.markets/ and wanted to use it to test out some of my API based trading.
What guarantees or structures are in place to make sure it doesn't end up like FTX?

Feetr Data Dump: BBBY TENX UNCY LUNR ARDS
Market data is an easier one to answer. We currently use https://alpaca.markets/ and they're pretty good, but we're also looking at https://polygon.io/ as they're the industry leader (but also 2k per month for what we require).

Can someone help me make an HTTPS request with an ESP32/How should I do this project?
I'm trying to make an HTTPS request with an ESP32 to this website alpaca.markets. I have the CA cert and I'm using WiFiClientSecure.h. Here's my code, main.cpp is underneath all that.

Exportable quote database for simulations?
Or you can sign up for a free account at Alpaca and use their historical data API. Then you can get data on many tickers with one function call.

Autoconf makes me think we stopped evolving too soon
> OCaml’s configure script is also “normal”
If that’s this OCaml, it has a configure.ac file in the root directory, which looks suspicious for an Autotools-free package: https://github.com/ocaml/ocaml

The Return of the Frame Pointers
You probably already know, but with OCaml 5 the only way to get flamegraphs working is to either:
* use framepointers [1]
* use LBR (but LBR has a limited depth, and may not work on on all CPUs, I'm assuming due to bugs in perf)
* implement some deep changes in how perf works to handle the 2 stacks in OCaml (I don't even know if this would be possible), or write/adapt some eBPF code to do it
OCaml 5 has a separate stack for OCaml code and C code, and although GDB can link them based on DWARF info, perf DWARF call-graphs cannot (https://github.com/ocaml/ocaml/issues/12563#issuecomment-193...)
If you need more evidence to keep it enabled in future releases, you can use OCaml 5 as an example (unfortunately there aren't many OCaml applications, so that may not carry too much weight on its own).
[1]: I haven't actually realised that Fedora39 has already enabled FP by default, nice! (I still do most of my day-to-day profiling on an ~CentOS 7 system with 'perf --call-graph dwarf', I was aware that there was a discussion to enable FP by default, but haven't noticed it has actually been done already)

OCaml: a Rust developer's first impressions
> It partially helps since it forces you to have types where they matters most: exported functions
But the problém the OP has is not knowing the types when reading the source (in the .ml file).
> How would it feels like to use list if only https://github.com/ocaml/ocaml/blob/trunk/stdlib/list.ml was available,
If the signature where in the source file (which you can do in OCaml too), there would be no problem - which is what all the other (for some definition of "other") languages except C and C++ (even Fortran) do.
No, really, I can't see a single advantage of separate .mli files at all. The real problém is that the documentation is often worse too, as the .mli is autogenerated and documented afterwards - and now changes made later in the sources need to be documented in the mli too, so anything that doesn't change the type often gets lost. The same happens in C and C++ with header files.

Bringing more sweetness to ruby with sorbet types 🍦
If you have been in the Ruby community for the past couple of years, it's possible that you're not a super fan of types or that this concept never passed through your mind, and that's totally cool. I myself love the dynamic and meta-programming nature of Ruby, and honestly, by the time of this article's writing, we aren't on the level of OCaml for type checking and inference, but still, there are a couple of nice things that types with sorbet bring to the table:

Notes about the ongoing Perl logo discussion
An amazing example is Ocaml lang logo / mascot. It might be useful to talk with them to know what was the process behind this work. The About page camel head on Perl dot org header is also a pretty good example of simplification, but it's not a logo, just a friendly illustration, as the O'Reilly camel is. Another notable logo for this animal is the well known tobacco industry company, but don't get me started on that (“good” logo, though, if we look at the effectiveness of their marketing).

What can Category Theory do?
Haskell and Agda are probably the most obvious examples. Ocaml too, but it is much older, so its type system is not as categorical. There is also Idris, which is not as well-known but is very cool.

Bloat
That does sound problematic, but without the code it is hard to tell what is the issue. Typically, compiling a 6kLoc file like https://github.com/ocaml/ocaml/blob/trunk/typing/typecore.ml takes 0.8 s on my machine.
