monster_truck··on Bend 2 and the Vibe-Coding Trap
Does anyone know where they bought the popularity and contributors from? I would like to do this for my joke language to fool unsuspecting users into using it seriously
monster_truck··on A heap overflow and SSO misconfiguration to compromise OpenAI internal repos
If you read the article, you will see this was within the acceptable scope listed on OAI's bug bounty program.

> monitoring the egress traffic

Oh so you mean the thing HuggingFace wasn't doing at all while also allowing any user's arbitrary programs to call out to the open web from prod?

No windows? axiomatic F32? I'll stick with Slopjective-C 3.0 thanks

Go check out the OSHA injury reports my dude. All it takes is something like a seemingly harmless hop over a short chain fence gone wrong. Where any other band would deform or break, that fucker's taking everything else with it.
monster_truck··on Recreating Voodoo Graphics and a Late-1990s Gaming PC on an FPGA
Went through almost the exact same situation with a $250 "used" 2U in 2006 that was full of the 15k rpm cheetahs. Had to cannibalize an emachine for a drive to boot from. It was far too problematic to do anything with the linuxes of yore, but it worked great for my network administration training VMs with Windows Server 2003. Those things were loud as fuck.

Ended up giving it away to an irc friend for the cost of shipping, they used it to start a minecraft server hosting business.

20 years later I now have nieces and nephews wondering how I know so much about minecraft, can't wait until they're a little older so I can host one for them. Funny how much and how little things change

monster_truck··on Recreating Voodoo Graphics and a Late-1990s Gaming PC on an FPGA
I mowed lawns for two summers to save up for a Voodoo 3000 PCI, still didn't even have half of what I needed. Parents covered the rest. Basically nothing I had hoped to be able to play worked. Spent an entire summer just trying to get Arcanum to even run, never did succeed. Learned a whole lot.

Goddamn if that buyer's remorse didn't scar me for life, the amount of researching I did before any purchase from then on was obsessive. I still think of the card fondly for what it represented to 10 year old me. This story does have a happy ending, we ended up getting a Dell XPS not long after with a Pentium 3 & a GeForce 2, back when they were still beige.

A tungsten wedding ring is a pretty silly/unsafe thing to have. I'll readily admit it's cool but I like my fingers too much to worry about degloving one of them. That said using it as an example of or point of comparison for most anything is pretty unrealistic.

Similarly I am not willing to wrap a LiPo battery around one of my fingers. Absolutely not. I suspect this is in part why we have not seen more smartwatch bands doing the same.

Node 26 added a bunch of profiling stuff that should make this a bit easier to pick apart. I'm being lazy and waiting for perfetto support on windows to get fixed so I haven't bothered yet

Once again I am asking, who is this person and why do they think they are qualified to tell me what's best?
monster_truck··on Dario, Please
I don't understand why hugging face is not getting more shit too. It is extremely embarrassing to get owned because you are letting arbitrary programs/users call out to the open web from the infra
monster_truck··on Ask HN: What are you working on? (September 2026)
Still working on my traffic simulator. Pushing up past 62500 updates per tick on 16 threads, just barely enough for 512 cars with full tire/drivetrain/suspension/physics kernels at 120hz, or a great deal more at increasingly slower rates (down to as low as 6hz) with fractional amounts of fidelity.

No we aren't. That's a theory that barely fits the lower bound of what we estimate the spin of the core to be
monster_truck··on CUDA for AMD on Windows
It's volatile as all get out and I'm not going to call out any token by name but if you needed another nudge, you can absolutely cover the cost of power and the 9070 GRE (or even XT) itself before the warranty expires by mining (without holding/speculating), which has been my breakeven point for sidestepping any guilt I might feel from buying another flagship GPU.

But to reason in other direction, unless you absolutely need cards right now, you could throw that ~$1440 in a 6 month CD and let the 4.5% pay for the tax or shipping on a 10090 XT or whatever RDNA 5 flagship when those drop in about as much time. If it lands anywhere close to what the rumors are indicating it should be a fucking monster.

You don't seem to understand what you're talking about
monster_truck··on CUDA for AMD on Windows
RDNA1 isn't good for a whole lot, even flagship RDNA2 cards are a stretch for many things. The lack of WMMA/matrix multiply/BF16 is too severe of a penalty.

The FP16 throughput on RDNA1 is both shader reliant and requires everything to be packed first. Even with 2 or 4 or 1000 cards, you would be consuming all of the available memory and memory bandwidth just packing and unpacking values, and if you really want to dump a hundred billion tokens into making it work anyways, you're only going to find out that even if you bother to sit there ferrying packed values to ram or disk before then issuing the instructions, paying that already severe penalty again when the values then have to be unpacked is so steep of a cost that the 256 BF16 flops/cu/clock's effective throughput is outright lower than simply doing it on a Zen 2 processor. You also don't have INT8 (or really INT4) on RDNA1 so the other RNS/CRT tricks aren't viable.

Sadly RDNA1's VCN2 also lacks actually good x264 bframe encoding support, or even P010 for 10 bit color, so what I'm saying is you should sell them. Used Radeon VII's are like $260, you'll go a lot further with those especially if you throw in a 7900XTX, and then augment that further with a 9070 CRE (you only want it for its int8 cores), and of course 128GB of ram.

E: And sure, that's 3, or ideally 4 GPUs, and a good bit of extra work. But that gets you up to more than halfway to the naive performance of a $15,000 MI300x in a surprising amount of cases, with additional strengths that it lacks. For far less than half of the cost

monster_truck··on 'Fingerprints' inside the Sun could reveal if it once swallowed a planet
Sounds reasonable to me.

But also what the fuck happens to the core of such a planet when that happens?

We aren't actually sure what gave our core the spin it has, right? I'm not fully awake yet but I think it's plain where I'm going with this.

Came here to say this.

I saw someone call out the stock performance of $OC (shingles) vs strong el ninos... it seems so obvious. What else is like that?

monster_truck··on Waymo pulls over, calls cops on juvenile riders who had 'ghost gun"
We used to raid the "dumpster" of nearly expired hostess products at the local hostess factory, and no bullshit fill the back of a jeep with twinkies and ho-hos and king dongs, then go drive on two lane roads and throw them out in front of oncoming traffic to try and get them to chase us.
monster_truck··on Waymo pulls over, calls cops on juvenile riders who had 'ghost gun"
The most I will say about the bullshit we got up to, as "the last chopper out" before literally everyone had CCTV, is that we made it our personal goal to get everything we did listed in the local newspaper's crime blotter
monster_truck··on Waymo pulls over, calls cops on juvenile riders who had 'ghost gun"
We used to do this and more with nerf guns, laser tag, and then paintball guns. You're not going to believe this but we even used to be able to ride our bikes 30 miles away from home without our parents being arrested. We played with fire in the park too. One time we even found porn there dude

The 90s were lit

Nah you're right tho let's imagine the worst case scenario. What if that person in the waymo had a nuclear bomb in their suitcase? There's only one option

monster_truck··on Nvidia is the central bank of AI
You must not be paying attention, they already have.

Intel is going nowhere but we all knew that anyways.

And again, you must not be paying attention, AMD is doing exactly what they said they would. No flagship for RDNA4 (just like RDNA2), RDNA5 flagship (10900 XT) coming right on schedule

monster_truck··on Copying login keychains between Macs fails on Secure Enclave Macs with Tahoe
This is so critical. Not just verifying the hashes, not just restoring, but actually booting into it and opening the top 5-10 things you're going to care about.

If it's your personal stuff, skip it at your own peril. If it's a paid responsibility, that's what hourly billing is for (this incentive was much stronger when I learned netadmin, back before nvmes)

monster_truck··on Kenyans Did College Students' Homework for Years. Then A.I. Arrived
I stopped short of flying out to do these for them but that is absolutely a thing too
monster_truck··on Stop making swap partitions—use swap files instead
Yeah, no. I don't care if I have 128gb or 2tb of ram, or what I'm doing with it (but especially in live/realtime scenarios), I'm always going to have at least one nvme dedicated entirely to swap.
monster_truck··on Kenyans Did College Students' Homework for Years. Then A.I. Arrived
Never went to college, but I made pretty good coin writing papers for friends who did.

It's always been my understanding that virtually everyone cheats (doctors/non-computer engineers aside)
