mechagodzilla··on The alien space of science: Coherent but cognitively unavailable directions
There was an incredible amount of investment into high-speed programmable power looms, and there were a number of innovations (later rediscovered by computer architects) targeted at 'card-saving techniques' to reduce the labor required to card-punch the designs, and to reduce the down-time of the looms. 'Double Data Rate' card readers (with a design interleaved on two chains running at half frequency), SIMD-style one-reader/many-loom setups, 'cross-border' looms that switched between two separate card loops just like a 'branch' instruction, machines to copy chains of punch cards.

What you're saying might have been true in the 18th century or earlier, but things were highly mechanized by the 19th century, and there was a lot of motivation to keep the big expensive looms highly utilized and amortize investment in punch card sets across lots of production runs.

mechagodzilla··on The alien space of science: Coherent but cognitively unavailable directions
I think the way computers developed is kind of an interesting example of this in the real world. Babbage basically realized the idea of a modern computer, but tried to build a too-complicated 'supercomputer' (40 decimal digit precision!) because he didn't know how incredibly useful a much simpler, more limited computer could be. We had to wait another 75 years and spend an incredible amount of money to develop relay and vacuum-tube supercomputers, before realizing that the idea could be scaled down, and something like a PDP-8 / PLC / microcontroller was incredibly useful for industrial control and, with sufficient cleverness, even do a lot of scientific computing.

I think if you went back in time you could pay some power loom engineers to build you a pretty decent 4-8 bit microcontroller operating at 1-5 Hz (comparable to power looms at the time) and computer-controlled textiles would have paid for the computer revolution 75-100 years ahead of time.

mechagodzilla··on Qwen 3.8 27B
Yes. I can split a model like this across 3 GPUs (a 1080 with 8GB and two Titan Vs with 12GB), and it's much faster than running it on 36 CPU cores. As long as it fits in aggregate VRAM, it seems very advantageous to do so.

mechagodzilla··on US is starting to see heavy job losses in roles exposed to AI
Relatively accurate (I think they're pretty close like 70%+ of the time). Significantly better than just projecting that the next five years will be like the last 5 years.
mechagodzilla··on Google's year in review: areas with research breakthroughs in 2025
You haven't really been getting 'human written and thoughtful content' for a vast swath of search topics for probably 15-20 years now. You get SEO-hyper-optimized (probably LLM-generated for anything in the last 3 years) blog spam. In terms of searching for information and getting that information, there are a lot of topics where an LLM-generated result is vastly better just by virtue of not being buried inside blog spam. The slop ship sailed years ago.
mechagodzilla··on GLM-4.7: Advancing the Coding Capability
It's not really an apples-to-apples comparison - I enjoy playing around with LLMs, running different models, etc, and I place a relatively high premium on privacy. The computer itself was $2k about two years ago (and my employer reimbursed me for it), and 99% of my usage is for research questions which have relatively high output per input token. Using one for a coding assistant seems like it can run through a very high number of tokens with relatively few of them actually being used for anything. If I wanted a real-time coding assistant, I would probably be using something that fit in the 24GB of VRAM and would have very different cost/performance tradeoffs.
mechagodzilla··on GLM-4.7: Advancing the Coding Capability
I've been running the 'frontier' open-weight LLMs (mainly deepseek r1/v3) at home, and I find that they're best for asynchronous interactions. Give it a prompt and come back in 30-45 minutes to read the response. I've been running on a dual-socket 36-core Xeon with 768GB of RAM and it typically gets 1-2 tokens/sec. Great for research questions or coding prompts, not great for text auto-complete while programming.
mechagodzilla··on macOS 26.2 enables fast AI clusters with RDMA over Thunderbolt
1-2 tokens/sec is perfectly fine for 'asynchronous' queries, and the open-weight models are pretty close to frontier-quality (maybe a few months behind?). I frequently use it for a variety of research topics, doing feasibility studies for wacky ideas, some prototypy coding tasks. I usually give it a prompt and come back half an hour later to see the results (although the thinking traces are sufficiently entertaining that sometimes it's fun to just read as it comes out). Being able to see the full thinking traces (and pause and alter/correct them if needed) is one of my favorite aspects of being able to run these models locally. The thinking traces are frequently just as or more useful than the final outputs.
mechagodzilla··on macOS 26.2 enables fast AI clusters with RDMA over Thunderbolt
You can keep scaling down! I spent $2k on an old dual-socket xeon workstation with 768GB of RAM - I can run Deepseek-R1 at ~1-2 tokens/sec.
mechagodzilla··on Electric vehicle sales are booming in South America – without Tesla
Kodak didn't really have the option to compete. Their business was largely film, which just disappeared completely, and even digital cameras got replaced pretty quickly with phones. There was nothing to pivot too for Kodak.
mechagodzilla··on System 7 natively boots on the Mac mini G4
Did you have to do anything special to get the SSD to play nice with OS9? I tried adding one to a 300MHz G3 iMac and it took forever to initialize on boot and would randomly stall a lot.
mechagodzilla··on AI is ushering in a 'tiny team' era
If anyone can pay-as-you-go use a fully automated factory, and the factories are interchangeable, it seems like the value of capital is nearly zero in your envisioned future. Anyone with an idea for soup can start producing it with world class efficiency, prices for consumers should be low and variety should be sky-high.
mechagodzilla··on Workhorse LLMs: Why Open Source Models Dominate Closed Source for Batch Tasks
Buy a used workstation with 512GB of DDR4 RAM. It will probably cost like $1-1.5k, and be able to run a Q4 version of the full deepseek 671B models. I have a similar setup with dual-socket 18 core Xeons (and 768GB of RAM, so it cost about $2k), and can get about 1.5 tokens/sec on those models. Being able to see the full thinking trace on the R1 models is awesome compared to the OpenAI models.
mechagodzilla··on Why DeepSeek is cheap at scale but expensive to run locally
Yeah, it was just a giant HP workstation - I currently have 3 graphics cards in it (but only 40GB total of VRAM, so not very useful for deepseek models).
mechagodzilla··on Why DeepSeek is cheap at scale but expensive to run locally
I use a dual-socket 18-core (so 36 total) xeon with 768GB of DDR4, and get about 1.5-2 tokens/sec with a 4-bit quantized version of the full deepseek models. It really is wild to be able to run a model like that at home.
mechagodzilla··on The ‘white-collar bloodbath’ is all part of the AI hype machine
Interns and new grads have always been a net-negative productivity-wise in my experience, it's just that eventually (after a small number of months/years) they turn into extremely productive more-senior employees. And interns and new grads can use AI too. This feels like asking "Why hire junior programmers now that we have compilers? We don't need people to write boring assembly anymore." If AI was genuinely a big productivity enhancer, we would just convert that into more software/features/optimizations/etc, just like people have been doing with productivity improvements in computers and software for the last 75 years.
mechagodzilla··on Deepseek R1-0528
I have a $2k used dual-socket xeon with 768GB of DDR4 - It runs at about 1.5 tokens/sec for the 4-bit quantized version.
mechagodzilla··on How University Students Use Claude
I've done all of those except tend livestock and build a house, but I could probably figure those out with some effort.
mechagodzilla··on The Decline of the U.S. Machine-Tool Industry and Prospects for Recovery (1994)
So applying this to China and the USA - the USA has a median household income of ~$80k, and China, in terms of purchasing power parity, has a median household income of $32k. China has a workforce of ~775M people vs 163M people in the USA. The USA has ~7M unemployed people. For the USA to stop importing goods from China, we would need to 1) stop consuming those goods altogether (even if they're intermediate goods that go into things we do manufacture), or 2) employ US workers to make those goods instead of whatever they're currently doing (either employed or unemployed).

Employed Americans largely earn a lot more than employed chinese people, and there just aren't very many unemployed Americans. Based on the value of imports to the US from China vs Chinese GDP($440B vs $17.8T), we import about 2.5% of their output, or the equivalent of ~20M people's output if we naively scale. I don't think there is any way around the fact that significantly reducing imports from other countries means we significantly reduce our consumption in absolute terms (i.e. we have a poorer standard of living), just out of spite for other countries.

mechagodzilla··on Show HN: Monkeys.zip – 3000 Monkeys on Typewriters
Ha! When I was first learning to program in high school, I wrote a 'distributed monkeys-on-typewriters' simulator. I somehow acquired a stack of surplus Pentium 100s that I had running in an unused closet at the school, communicating with each other over IPX. I remember the server had a fun 'Guess-operations-per-second' (GOPS) realtime display.
mechagodzilla··on I genuinely don't understand why some people are still bullish about LLMs
I think we can already get open-weight frontier class models today. I've run Deepseek R1 at home, and it's every bit as good as any of the ChatGPT models I can use at work.
mechagodzilla··on I genuinely don't understand why some people are still bullish about LLMs
That's been the 'endgame' of technology improvements since the industrial revolution - there are many industries that mechanized, replaced nearly their entire human workforce, and were never terribly profitable. Consider farming - in developed countries, they really did replace like 98% of the workforce with machines. For every farm that did so, so did all of their competitors, and the increased productivity caused the price of their crops to fall. Cheap food for everyone, but no windfall for farmers.

If machines can easily replace all of your workers, that means other people's machines can also replace your workers.

mechagodzilla··on I genuinely don't understand why some people are still bullish about LLMs
None of that means that the current companies will be profitable or that their valuations are anywhere close to justified though. The future could easily be "Open-weight models are moderately useful for some niches, no-name cloud providers charge slightly higher than the cost of electricity to use them at low profit margins".
mechagodzilla··on The Impact of Generative AI on Critical Thinking [pdf]
After being a professional programmer for ~20 years, and recently playing around with leetcode - my main issue with leetcode is that there's almost no overlap between leetcode problems and the problems I actually encounter in the wild. The validation tests often have silly corner cases that force you into a single answer to avoid timing out. It's frequently as much work to understand what the problem is actually asking you as it is to implement a solution. Just like I've found ChatGPT to be pretty mediocre at writing the sort of code I work on, but others swear by it, maybe some peoples' dayjob actually looks like writing leetcode all day? I know a lot of interviewers use it, but it feels so disconnected from actual engineering work.
mechagodzilla··on Would You Rather Have Married Young?
I married at 22 and moved to nyc. I lived through meeting peers that thought we were freaks (“you two are definitely gonna get divorced”), to the gradual normalization as we got older and more of our friends married. I knew lots of people that transitioned from young and invincible and definitely never going to get married to dismayed at coming up on 40 and feeling like they hadn’t quite started “real life” yet. I don’t like the article’s depiction of the guy “taking her under his wing” had they gotten married earlier, but I will say that there is something great about sharing your youth with someone unequivocally on your side, if life gives you the opportunity.
mechagodzilla··on Anthropic raises $3.5B at $61.5B valuation
But the open models create a (rapidly rising!) 'floor' - models that are worse/less capable than the best open-weight models effectively have zero economic value to their creators, even if they just spent $10B to create them. What fraction of queries require a better-than-R1 answer? Every time that floor rises, it puts even more pressure on whatever narrow, temporary advantage these closed companies can achieve to actually justify the valuations.
mechagodzilla··on Anthropic raises $3.5B at $61.5B valuation
And the Llama series, and they have half a dozen closed competitors with similar performance/capability.

It really seems impossible to justify these evaluations from any kind of economic perspective.

mechagodzilla··on GPT-4.5
I think that's the right interpretation, but that's pretty weak for a company that's nominally worth $150B but is currently bleeding money at a crazy clip. "We spent years and billions of dollars to come up with something that's 1) very expensive, and 2) possibly better under some circumstances than some of the alternatives." There are basically free, equally good competitors to all of their products, and pretty much any company that can scrape together enough dollars and GPUs to compete in this space manages to 'leapfrog' the other half dozen or so competitors for a few weeks until someone else does it again.
mechagodzilla··on Claude 3.7 Sonnet and Claude Code
If you don't need to pay for the model development costs, I think running inference will just be driven down to the underlying cloud computing costs. The actual requirement to passably (~4-bit quantization) run Deepseek v3/r1 at home is really just having 512GB or so of RAM - I bought a used dual-socket xeon for $2k that has 768GB of RAM, and can run Deepseek R1 at 1-1.5 tokens/sec, which is perfectly usable for "ask a complicated question, come back an hour or so later and check on the result".
