@Aissen yeah that is what I'm doing small iteration at a time :-) i've read my joel on software in the distant past https://www.joelonsoftware.com/2000/04/06/things-you-should-never-do-part-i/

non taken! and my rants neither should be taken too seriously. i'm basically and idiot trying to find idiomatic patterns :-)

@pavel @vbabka that's about what i run in my test images. actually i do have bash because kselftest requires it so that might be problem :-) it can't be worse performer than running RISC-V on FPGA, which I did for work purposes at some point...

@vbabka @pavel i need to check for fun what are the lowest specs for atari m68k. i possess STE with 4 megs and ultrasatan ;-) maybe i could create a config for it to my buildroot based shenanigans.

Well, I heard someone working in game industry that the figures I get with Rust when compiling and linking are in par with C++ projects :-) Like compiling Unreal Engine for instance.

Based on Unreal Engine figures 9950X(3D) should be a decent CPU so with "matching" parts on non-ECC memory (with ThreadRipper I'd actually go with ECC memory), we are talking about 4k investment so be it.

@litchipi Yeah, actually it is the linking that is nasty given the build artifacts that Rust makes but yeah you have a point :-) This was mostly just my stupid ranting that helps me to get over the work day stress, that's the weight of this nonsense really :-)

This goes to non-scientific speculation at best but I'd figure that over the time more innovation will be done for the linking phase as you could probably take advantage (in caching) of the heuristics of the linking phase (blobs build a huge static blob) perhaps... Perhaps even doing some of the compiler backend work specifically targeted to Rust.

This is literally my certificate of ownership for my downtown apartment in Tampere, Finland. I'd call this a proper stock :-) Especially love the tape fix in the middle.

Still I'm now looking into putting my place to digital register and hang this to my wall...

@raven667 yeah, so no apologies needed. I think you got the post right, I was not 100% dead serious with the post in the first place :-) Sometimes you need to do posts like this just for ranting and blow some steam out of your system... Especially on stuff that you need confront at your work on daily basis...

@raven667 BTW, I got confused with your 10 k comment because SGI workstation cost more like 50k-100k. Today expensive workstation would cost 10k-20k :-) So in that sense also high end is more affordable than ever.

@raven667 Also, I think your points are fair :-) Not necessarily disagreeing.

Zed has been BTW a great help browsing large projects. I don't know how its LSP engine is exactly implemented but it is probably caching the JSON data somehow. It can show immediately errors, warnings etc based on data and then it refreshes that. E.g. with my Thinkpad it helps a lot :-)

@raven667 Damn, if I ever make a rap music video, instead of throwing dollar bills, I'll be writing Rust in that with a computer having the most expensive 12k ThreadRipper CPU ;---) Not very likely but now I have a plan!

@raven667 Also programming connects straight to giving equal opportunity to various groups of people. Most people cannot afford $10 k computer but most can afford e.g. laptop, which you can e.g. use to hack kernel with C ;-)

So yeah this is really a huge downside in Rust from my point of view, which cannot be ignored...

@raven667 I don't want to spend 10k to use a fucking text editor if I'm totally honest with you :-)

My M2 Pro was the best specs version with about 3k price. That should still in 2024 perfectly good development machine. And it is neither too environment friendly to upgrade your hardware constantly only to write code...

That 3k was MOST I've ever paid for a computer.

@be_far Yeah, this was good point actually. If I use sccache compilation is only few percent of the total build and linking takes > 90% even with the fancy mold linker is used...

Having used Rust professionally for a while I can say that it is programming language that literally requires latest desktop CPU from AMD or Intel, or to be fully lean something like ThreadRipper. Minimum RAM is rather 64GB than 32GB.

I guess this is progress when a programming language has higher spec requirements than any of the AAA games I'm aware of ;-) No wonder they call Zed as "multi-player editor".

My work Thinkpad melts with Rust and my own M2 Mac Mini Pro (12 cores, 32 GB RAM) can just barely keep up in phase.

PS. I wonder how much compiling Rust code has an effect to the climate change annually ;-) With a Threadripper I could almost literally warm up my house just by compiling Rust.
