Archit3ch··on Why are good developers so wary of agentic development?
The best style of agentic development is when you tell it "no, you should do this instead". That implies that you have the knowledge to do so.

Non-developers that try vibecoding default to a "yes, and" style.

> leaving Anthropic providing about 5x the value on their plans

5x is calculated in terms of API costs, nobody pays those extreme Anthropic prices outside enterprise users.

> like they didn't just double the cost for most users

Most users aren't on their $200 plan. Most users (including on the $200 plan) continue being subsidized.

I rather enjoy OpenAI's focus on cost-per-task.

I'm optimistic about them tackling frontier intelligence next. Astra 6.1 please?

Archit3ch··on Superhuman Hardware Design Is the Easy Part
> When you start adding variables to the search space (emi interference, matching routing impedances, heat management, mechanical integrity, etc) the search space grows so big that any non-expert will become lost in it.

Have you tried Astra?

I'm designing an analog ASIC. It will suggest e.g. transistor matching. You can also give it hints for layout.

You still need to validate with SPICE simulation (and obviously silicon).

I'm also looking into non-LLM scripts that use brute force aided by heuristics (e.g. lookup tables) to efficiently search the solution space.

Archit3ch··on Gaming on Linux without cheating
Always has been. Your signed Android can open banking apps.
Archit3ch··on Gaming on Linux without cheating
I haven't kept up with mainstream gaming in a while. IIRC, EAC v1 doesn't require TPM 2.0 and thus is security theater, right? An attacker could just tamper the binary.

The same goes for a binary protected by TPM 2.0, but the attacker would have to re-implement the protected parts. The defender's bet is that this should require too much effort/time/knowledge to bother.

Archit3ch··on Gaming on Linux without cheating
Before: it wasn't possible to run these specific games that require this competitive anti-cheat on Linux.

So you can ignore the newly-enabled games in this proposal and you're not missing anything you had previously.

Archit3ch··on Show HN: FM-1 synth emulator with a reverse-engineered CPU and WebAssembly JIT
I thought about it, but no AUv3 integration and of course slower-than-native code. Not that it matters for emulating these chips.

Actually, let me grab it. [...] Hmmm, better than expected. It works out of the box, but there's note latency compared to native apps. Also, zooming and text selection appear even when you don't want them. Janky for real playing, okay for a demo.

It doesn't have nearly enough power for proper circuit modeling. You might as well use samples.

Archit3ch··on Reverse Engineering of the M-VAVE FM-1 Pocket Synthesizer Firmware
I don't get the hype. A processor 10'000x less powerful than a 2021 M1 iPad, sound quality of late 90s to early 2000s VA. It's cheap and sounds the part.

You CAN get an STM32 to sound beautiful and fun (shout out MI Braids), but in 2026 that's available in VCV Rack for free.

15 meters is a tragedy. 15 million is a statistic.
Archit3ch··on Why Common Lisp is now the best programming language
APL doesn't expose pointers. At the very least, this would make interfacing with other languages impossible.
Archit3ch··on Why Common Lisp is now the best programming language
I have a similar experience with Julia. Very fast iteration, down to native code when required.

Every chip? I bet it can't target analog chips, what with the pointer talk and all...

Archit3ch··on GPT-Synopsys: Frontier Intelligence to Revolutionize Chip Design
You get your non-deterministic process (hired humans or LLMs) to create deterministic scripts (='generators' in EDA terms), which can then be audited, corrected, etc.

DRC/LVS/PEX/SPICE are deterministic, but the tools themselves are not without faults.

Astra is amazing with open PDKs. ;)
Archit3ch··on The state of SIMD in Rust in 2026
Note that ISPC does not handle symbolic math e.g. sparsity preserving linear solvers or equation simplification a la Mathematica. Manual ASM does. ;)
Archit3ch··on The state of SIMD in Rust in 2026
2x/4x/8x is still thinking in terms of autovec.

I'm getting 50x faster code with manual ASM. That's the difference between audio code that runs in realtime and code that does not.

The competing implementations use SIMD and native code, autovec works nicely there. I symbolically invert the LinAlg system at compile time.

Archit3ch··on The state of SIMD in Rust in 2026
Hot take: there is no portable SIMD.

You can either have performance (=write manual ASM for each platform), or portability, but not both.

What so-called "portable SIMD" libraries give you is "portable auto-vectorization". "Portable performance" is a global property of the algorithm. Relying on auto-vectorization will result in e.g. sub-optimal register spills in practice. The microbenchmarks will look great, though. ;)

Archit3ch··on Apple M6 Pro Achieves the Highest Single-Core CPU Score in Geekbench 7
> AVX still wins though.

On what, microbenchmarks? I have realtime audio workloads where the hot loop is essentially linear algebra. Exactly the kind of work that suits AVX2/AVX512. Guess what, Apple Silicon still pulls ahead because real workloads are branchy, cache-hungry, full of dependencies and do not line up in 8 neat f64 operations per cycle.

Archit3ch··on Run macOS Software on Linux
> Is there some really amazing Mac only software that would justify the effort ?

As others said, the killer app is XCode. Even if you can technically get it to run, you'll still need the full support and test flows of a native solution, so you might as well follow the proper path and use a Mac.

I can get Visual Studio to run in Parallels today. I still test with a real Windows machine.
