What's the easy way here? Linking CUDA into your Rust binary?

Every engineer who's worked with "agentic" workflows can tell that this is entirely generated with very little tweaks. It's embarrassing.

This is a strong assertion that's directionally wrong. No matter the economy's state or any AI progress, experts are always searched for.

How are FPGAs "bruned into silicon"? Would be news to me that there are ASICs being taped out at CERN

The millstones of the gods grind late, but they grind well. It depends where you're from -- there is always potential for dramatic change in a people as obedient as the German.

I do hope that sufficient humiliation will suffice for DB leadership to enact harsh measures. German precision and punctuality are still there in its people. It's not lost yet.

konradha — Fri, 05 Dec 2025 11:50:44 +0000

I've been trying my hand at RL envs for various sparse matrix algorithms in CUDA. It's easy to generate code that "looks good", "novel" and "fast". Escaping the distribution and actually creating novel sequences of instructions or even patterns (has any model come with something as useful as fan-in/fan-out or double buffering patterns that's now ubiquituous?) seems difficult to say the least.

80kms for the longest day, amazing. The most I achieved in the north of Berlin was about 30kms/day. Also, is "Shengan" a british spelling quirk?

I know some people who took a look at their StaSi files. Today's really different compared to what happened then: There wasn't someone from inside your inner circle transmitting every joke and every utterance to "law enforcement" for them to build kompromat. Sure, nowadays your every move is sold to god-knows-who but this will not impact your ability to choose a course of study (which may or may not suit you academically). You can get a job anywhere provided you have clearance and education needed. You will not look at pictures from your childhood and realize that three out of five people sold you out to get ahead in the queue to acquire a car. Your most intimate thoughts and acts aren't recorded for random bureaucrats to get a laugh out of. Please think again before equivocating "den Realen" with modern democracy. Neoliberal, consumerism societies definitely have their flaws but you're definitely better off on the freedom scale.

Would you happen to have sources on the three orders of magnitude speedup coming at no cost? I'd assume porting + data movement considerations making this task non-trivial.

konradha — Mon, 28 Aug 2023 17:26:13 +0000

LFortran is not necessarily using LLVM IR to compile. It's building up an ASR [1] structure that's already being used in the LFortran-specific backends. Potentially it can make full use of Fortran semantics!

'Regime shift' is a fairly common term when talking in the context of time series.
