<p>Sign me up.<p>Used to be a big Event Of The Year when my grandpa found one after spending all day out in their 'garden' (a few acres bordering deep woods). I remember being maybe 11 when he found one, let me try and figure out how to crush it, I couldn't. He showed me how to use the butt of a butterknife and leverage to get the fuckers<p>I don't live anywhere near a proper forest and we've had several close calls this year, I caught one crawling across my scalp when I was getting into bed last month. Went and got tested just to be safe<p>I know feeding crows is really fun, but please don't. It's very important that they get hungry enough to eat mice sometimes. Same goes for deer, the past couple of years I've had them walk _towards_ me and my dog instead of bolting, presumably because someone is feeding them (by hand, not garden raiding)</p>

<p>You can derive a pretty solid yardstick of how things are going for China by what you can find on the aftermarket, currently there is a glut of nvidia 4080s that have had their memory doubled up to 32GB. I'd have to assume they got a good deal buying up piles of H100s or whatever else was eating rack space, or potentially took a loss because they have hit the constraints of the # of cards they can rack.<p>On the OEM side of things 9070/XTs are also shooting back up in price now that we have <$100 USB 4 egpu docks.<p>People like to complain about how expensive things have gotten but I think it's pretty neat that there's so much pressure for throughput that it's even viable to buy 4 docks and 4 $850 GPUs and still save money over a single 48GB card.</p>

<p>It's ~a traffic simulator with the fidelity of a rally sim like DiRT Rally or Asseto. Full engine/drivetrain, grip modelling with tire deformation, suspension, aero, collisions, etc. I just really like Rally Racing and Car Accidents<p>The absurd goal was to be able to simulate all of the active traffic in NYC, so 3-500,000 cars, without using any of the macro flow corner cutting that you see commercially or academically.<p>Initially thought that one machine was not going to be enough to do this in realtime so I spun off a very big fork and built out a webtransport stack to split the effort over a local network. It was promising until I also wanted to cover the highway in thousands of giant beach balls [1] [2].<p>In the process of leveraging codegen to shrink the data that needed to be relayed by >10000x (packing and dynamically updating sparse continous arrays of floats), threw in a fuckton of LOD work (both spatial & temporal), statistical aggregation, and a lot of differential equation bullshit to derive LUTs. It's at the point where a base model M2 mini can handle much more than that by itself. All of the networking effort paid large dividends in cross thread coordination and lock-free data passing. Went from struggling to fit each of the sim kernels for just 32 cars @ 60hz (~11ms) to 0.03, 0.0003ms p99s with the corresponding jumps in car count (north of 32k/thread). Multiplayer works well enough, it falls apart where it should (~128 people or LLMs driving around in the same square quarter mile, and a great deal more NPCs, latency permitting)<p>The remaining work is making it look and sound cool as fuck. Building out a physically-based audio synthesis engine that simulates the pulses of exhaust gas starting from the cylinder count/size/firing order, intake and exhaust count and size, header and exhaust configuration, and another one for the tire sounds, and another one for the collisions, and then rendering those out to wavetables so it scales and frees up the cycles for occlusion. And then getting it to visually render and control performantly in a browser tab, lots of instancing and shader work.<p>There's also some bullshit cooking that uses the motion estimation built into GPU video compression engines for ... other purposes at stupid low latency. I figured that's what Waymo had to be doing so I let it rip<p>It's fucking nuts, I'm having so much fun :) It will be done when it's finished<p>[1]: <a href="https://i.imgur.com/BDQSuLv.png" rel="nofollow">https://i.imgur.com/BDQSuLv.png</a>

<p>Writing custom WMMA/MFMA kernels for an exact integer matrix multiplication library that uses RNS & CRT + Int8 GEMM to get ~90% of the theoretical i64 TOPS output from a 7900XTX (3.9 TOPS vs the 0.5 or so you get with naive hip-direct usage)<p>I'm not sure if you think that's a lot, but that was barely even 8 hours. I've had 200B+ months lol</p>

<p>Thank you for the advice but it looks like it's an issue with Deepseek's dashboard, I think they are calculating the value incorrectly.<p>This prompted me to dig back through the logs, it seems to be closer to 96% at its absolute worst and 99.3 at best.<p>I only sell to openrouter, would much rather support Deepseek directly.</p>

<p>In my experience MTP's speed increase doesn't seem to justify the apparent loss of success at the edge, it would have to be at least 4x faster to meaningfully churn through the first 3 failures in the time it would have taken to do it once without<p>What exactly are you doing that the prompt is eating an entire 65536 window? Surely it would be better to let it use any number of approaches that call tools to access that in parts and reason/summarize to an output file as it works through the whole thing. This allows it to keep the initial instructions in the start of the window and toss out the middle as it goes. IME many people who have written off local models entirely are, for lack of a better term "not holding them right" and consider them worthless.<p>Definitely also try IQ4_NL for K/V if you haven't. Because it's non linear it's far more hit/miss from model to model and especially quant to quant, I've found generally that it shines brightest when you start with a Q6K+ quant that you otherwise wouldn't bother with because of its size, which it then makes up for in both inference speed and often a larger context.<p>I do agree about Glimmer, though. It is quite good, far better than the benchmarks let on, especially in heavily agentic cases where it needs to rampage around the OS and utilize many different utilities to zero in on things. It is especially good at being told to try something itself, and if/when it fails, try Qwen, and if Qwen can't do it, call out to Deepseek.</p>

<p>Extremely. They are quite slow laterally (a couple knots while docking), the lateral currents (which are not constant or unidirectional) reach 2-4x+, throwing them into whatever happens to be in the way.<p>AFAIK the bigger issue is that the boats are grounded so violently when the water recedes that the hulls get destroyed before they even have a chance.<p>This tends to be why they put everything they have into getting further out to sea the moment a warning is issued.</p>

<p>the $/gb of storage is declining, which is more relevant here.<p>The big boogeyman that noids have insisted on for the past ~30 years is that intel agencies are saving everything they can to try and decrypt it later. Thankfully for us, the rate at which internet traffic grows year over year massively outpaces the global production capacity of spinning rust.<p>The last time I did this napkin math I think the collective global production was barely enough for some small fraction (maybe 1/8th or 1/12th) of everything.<p>It isn't exactly something that can be done in secret. Everyone else has to buy hard drives too, there are only so many sources of raw materials, places that can refine them, etc<p>E: I think the most relevant thing to avoid if this is a concern for you would be commercial VPNs. There's a reason fiveeyes doesn't want them to be banned. They can almost assuredly save piles of money by simply coercing providers into allowing them physical access to leverage side channel attacks</p>

<p>One of the biggest problems IMHO is that they aren't trying to usefully accelerate it on anything other than specialty hardware or 64+ core EYPCs so nobody gets to play with it at home.<p>ex: A 7900XTX barely gets 0.5 TOPS of u/i64 naively w/ hip-direct, 5-10s just to bootstrap!<p>I needed more throughput for non-crypto i64 diff eqs so I slopped up a lib that uses RNS & CRT w/ Int8 GEMM... it's good for ~3.9 TOPS (~90% theoretical peak of the RDNA3) at prod relevant FHE sizes (2048/4096). This lowers bootstrap time to 200-500ms. It was basically free real estate lol<p>It isn't done yet (not worth the heat in the summer), going to finish it in the fall. Have been accumulating cloud credits to do CDNA3/4 validation in the meantime (If anyone has some to offer do let me know!)<p>It's neat but very dry, uses semantic contracts so you tell it what kind of mult you need and it chooses the validated best backend. If you're doing lots of smaller ops (512, 1024) it will use custom WMMA/MFMA kernels, dual issue, and grouped dispatch to land >70x over hip-direct.<p><a href="https://github.com/doublemover/RNS8/" rel="nofollow">https://github.com/doublemover/RNS8/</a></p>

<p>The biggest one tends to be that they are simply too old, or have retired already. The retirement age is 56, with effectively no exceptions.<p>Virtually nobody lasts that long. If they don't end up needing a prescription that disqualifies them before 50, they end up getting incentivized to leave at 50 anyways.</p>
