This is fantastic. I have a TUF-3 but to use one to tune an acoustic was a real trip :)

Yep- there’s some issues representing complex numbers in 3D space. You may want to check out quaternions.

right, people will just tell you the best places and things to invest in ...

during a game of chess: "hey why'd you make that move?"

"hey why'd you make that bid?" is a valid question that must be answered during a game of bridge..

Good article, but I really really enjoyed the (non-deterministic!) falling objects with physics engine at the top of the page.

I'm working on a oldskool video game:

https://valtima4.com/

It's the Survival Crafting RPG you would have played on your Apple II back in the 80's.

You can think of it as Valheim's gameplay crammed into the tile-based ui of the old Ultima games.

It has a procedurally-generated open world with towns and NPCs to talk to, all the resource gathering, mining, crafting stuff you'd expect in a modern survival game, and some good old fashioned dungeon crawling to boot.

I've been working on it off and on for the last several months. Let me know what you think!

Looks really cool, I'll try it later.

Just wanted to let you know that for me, on FF and Chrome, your blog is rendering rgba(235, 235, 235, 0.64) text on white BG, and I'd really like to be able to read it.

Edit: Also immediately reminds me a bit of UnReal World[1], in a good way

That's nothing; there's an Amiga demo where it runs in the machine without touching the Motorola CPU ever.

There's a whole open challenge[1] - but you might be thinking of this[2] prod.

coldcity_again commented on Ask HN: Help with LLVM    · Posted by u/kvthweatt
i_don_t_know · 2 months ago
I haven't used LLVM in ages. I think it injects references to functions in the CRT when you do certain operations in your code. _fltused is one of them, and I think _ftol? or something like that for floating point numbers is another one. There was also a "security cookie" at some point in the MSVC libs. Unfortunately, I don't remember the linker flags to get rid of that reference, IIRC it had to do with runtime stack checking.

These references do not appear in the .ll file. They are injected when the .ll file is compiled to object files.

I think something in your code triggers a reference to one of the other injected functions and that pulls in the CRT.

Try compiling your test file into an .o or .obj, that is, without linking. Then dump the symbols in the object file to see what symbols are referenced. I suspect you'll see other references to symbols in CRT and you will have to replace those as well with stubs.

Unfortunately, I don't remember the linker flags to replace/suppress the default CRT libs. Well, actually, you might compile to .o / .obj and then manually link on your system. If you're using MSVC check the options to its "link" executable (I don't remember the exact name of the MSVC linker).

coldcity_again · 2 months ago
Possibly unhelpful for OP, but for MSVC try /NODEFAULTLIB for specific libraries, or IgnoreAllDefaultLibraries to remove everything not explicitly specified to the linker.

On x86 only, if you need to cast floats, try /QIfist (deprecated) to avoid hitting _ftol. Doesn't work for x64 or ARM.

you can accept bitcoin at any confirmation you want, it isn't a policy
coldcity_again · 2 months ago
in bitcoin terminology it is actually called policy rather than consensus, meaning you can choose your own config and still meet consensus rules.
