it was a dreadful, useless computer, even then

Unlike the PS3 which the US Air Force bought 1,760 and clustered into the 33rd most powerful** at the time.

(**Distributed computing is very cheat-y compared to a "real" supercomputer which has insane RDMA capabilities)


We had clusters of them in university too.

If all you needed to do was vector math, a dedicated vector processor with eight cores that are capable of running as fast as the extremely wide bus could feed them with data is the way to do it. You couldn't buy anything close to it's capabilities (for that specific task) for the money.

I remember the course we used them in being hard as hell, and the professor didn't really have any projects prepared that would really push the system.


From what I understand (may be wrong) this is exactly the reason that they stopped allowing Linux installs on PS3s.

People were buying them just for this purpose. However, the consoles were sold at a discount because Sony expected users to buy games, controllers, etc. If someone bought a PS3 alone, without anything else then Sony lost money.


It coincidentally happened around the time this came out.

Then they sued him. There's a bunch of archived links on his Wikipedia page.


"it was a dreadful, useless computer, even then"

So you don't dispute the thesis that the hypothetical general-purpose machine described in the comment would have needed to have been been better than the PS2?


Neat!

Similarly I have been thinking about a van so I can sleep in air conditioning between track day sessions and/or races. I also want to be able to bring materials to my workshop. Not sure what I will do, yet.


I like it, but it is also giving me Lego person vibes


the rockchip hw is really exciting lately, in general. i am using a bunch of them for streaming.


Aren't they GPL violators?


Seems that way, but if you want hardware, you have to buy the hardware that exists.


even before AI: when i raised from USV the second time, my lawyer and theirs had already negotiated paperwork with another company, so everyone decided to reuse it. it was MUCH cheaper…


Do you still get deals from angellist (your angel.co link now leads the HR Site)?

The angellist site itself seems to hide the startup/pitch side


supercars from 1983 are very different than modern cars. they have traction control now and are much tamer.


I think this understates just how fast modern performance cars have gotten and how unsuitable they are for public roads.

A Ferrari 296GTB sprints from 0-100mph in 4.7s. The 1983 Lamborghini Countach I had a wall poster of as a kid, took 12.1s (and a relatively leisurely 5.4s to get to 60mph). The Ferrari is pulling well over 1G longitudinally during this time, enough to induce tunnel vision in some people and warp your perception of speed and distance.

Compare someone accelerating at full throttle through that tunnel in the Countach versus the 296. The 296 would reach 2-3x the speed the Lambo did by the time they reach the curve where he crashed. Human brains can't process and react to surprises 3x as fast as they could in 1983. Even if they could, at 2x the speed your braking distance increases 4x. No amount of traction control or electronic nannies can make up for this. Nor can the electronics bypass the laws of physics - I think for many they provide a false sense of security.

And while there have been huge improvements in passive safety too, they are tested at speeds like 40mph, not the 90mph+ it is estimated Vince's car was going. This is why Teslas have the highest crash safety ratings there is, while also have the highest rate of fatal accidents.

Not to take away from the tragedy that is Vince's death. I enjoyed many hours playing MoH and CoD as a youth and this is extremely sad news. But as a car enthusiast, I am using this as a sober reminder of how quickly things can go wrong at speed.


> Nor can the electronics bypass the laws of physics

The only equation that really matters here is KE=.5mv^2

The difference in danger between two arbitrary speeds is not linear. It is quadratic.


If that crash video on X is accurate he was racing on public roads. If so, zero sympathies.


My point was more about how the cars perform when turning. Of course you will get in trouble with way too much acceleration.

The main problem with traction control etc is that they are ridiculously capable… until they aren’t. Minor things will cause you to lose it in a 1983 supercar that a modern car will just quietly fix. But nothing will save you if you floor it in the wrong place. Even a Miata without TC can have problems.

(I dailied a McLaren for a while, and at some point turned TC fully off on a track and promptly spun it at maybe 40 mph)


Thanks for clarifying and agree with that.

Having owned a few Miatas I can attest that they spin if you're not careful on slippery surfaces. :) TC/DSC is a lifesafer particularly when driving at normal speeds.

Driving my NA (pre-TC) was a pleasure in part because it had so little grip and so little power, that it would let go progressively and at low enough speeds that I could always catch it and not risk a serious crash. Between the squealing of tires and the immense body roll, I always knew how much grip I had left to play with. I now drive a 911, and stability control stays on permanently because I'm not confident I'd always catch it if I accidentally give it too much power (or lift off too quickly) in a turn.


But of course there is a button to disable it.

I still rather drive (get driven) a modern tank like suv. Or truck/bus conversion. I see these young/hip people spend countless hours in the gym, spending 1000k+/mo on supplements etc to 'live forever' only to wrap themselves around a tree at a young age on some superbike or car.


...or getting run over by a tank like suv with limited vision around the car (it's tank like after all) while cycling.
