I'm a lispworks user for a few projects. The killers, generally, for an enterprise project are the smaller binaries and java interface. I know of a few places that write gui apps in lispworks, but many (most?) projects with a user interface use some web framework stuff and only do the backend in lisp. The java is a killer feature for lisp adoption. A lot of companies use java heavily and being able to easily interface with that stuff is often a technical requirement and if not a technical one, a management requirement.

Question: is there a reason pid type control is never a thermal option? Or put another way, is there something about the desired thermal characteristics of a computer that make pid control undesirable?

I've only every seen something like this in really high reliability equipment because they're worried about repeated thermal expansion causing cracks in the boards/solder joints. There is, often, heaters available for use if the temperature gets too low. For most equipment I think that the juice just isn't worth the squeeze so it isn't done.

This is anecdotal but I use pci passthrough and drm hasn't yet been much of a problem except for older games.

Orangeburg pipe is the tar paper stuff. It's a time bomb. Not only does it break down with use it also flows (flattens with gravity/overburden pressure, bends over unsupported sections run through walls/floors, etc) over time as well, especially in a hot environment. So even if it doesn't get much use it will collapse and/or stretch and break.

It's not just economics there. Weimar was a garbage fire from top to bottom, and that made extremist groups that promised to fix the nation actually viable. People are much more willing to vote for loons if everything is broken and no one has really done much of substance about it. In their eyes they have nothing to lose. A common thought then was "Maybe these nazi/communist/anarchist guys can fix things. They seem well organised even if they are a bit wacky. How could they make things worse? We'll just vote them out if they don't deliver the goods like we did the last guys".

Little did they know of what was to come.

No I'd bet he's getting avgas. That's avgas price territory.

I’ve found this “First Greek Book” [1] to be a good starting resource. It gets you through Xenophon’s Anabasis which is a great starting book.

But depending on the altitude you're at getting that mask on is wishful thinking. Don't bet on your pilots being conscious after a plane depresses.

Both are kind of correct. If it's laying where it shouldn't be it's debris, but if it's plowed through the windshield it's damage.

They’re great cards and easy to write drivers for. I still use one in one of my thinkpads for wireless because it used to be the only card supported by 9front and plan 9 back in the day.

Almost none came from Airbus. Really you could almost say they came to Bombardier’s aid.

No, the SS did in fact have academics in their ranks to produce things that link the SS/Nazism to the "German past," to scientifically show the "superiority" of the German people, and to "quantify" how exactly everyone else was less human than the German "Aryan" peoples.

The SS was much more than a military group. It was a weird mix of paramilitary organization, police force, academy of sciences, academy of arts, men's club, cult, and think tank.

Total conjecture but it was probably factored in. From my standpoint if I knew it was going to sag, I would use that to my advantage if I could and, if not, at least factor it in.

Also if we suck the CO2 out of the atmosphere we could turn it into petrochemicals and fuel which would help with making existing things carbon neutral.

I wish I had a better math background, and I wish I was taught both the importance of testing and how to write useful tests.

Inferno and Plan 9 sorta had this. Octopus and Plan B were both allowed picking up where you left off on some other machine.

Yeah, we're still here.

Why? That's akin to saying a mechanical engineer isn't worth their salt unless they know how to design and implement software. They're two different specialties that do different things. To be a good mechanical engineer you absolutely don't need to be good at making or even have tried to have make software.

This is cool. I’ve thought about carbon sequestration a lot using big nuke plants/solar plants+air liquidification+some plant to distill off and turn the CO2 into like methane or some hydrocarbon. My thought here was put half back in the ground and sell the other half to fund the installation/make sure we don’t run out of hydrocarbons. The olivine process, though, is probably easier because it takes much less infrastructure and is more fire and forget. We need some method for sequestration running at scale now (probably multiple). With the amount of CO2 in the atmosphere already, the amount continuing to go in, and the amount of inaction we’re pretty fucked. The current solution (getting the whole damn world to reduce emissions) is unrealistic. Even if we stop putting more in, it’s already there and we’re already fucked. It’s a day late and a dollar short. The countries willing to face this need some way to save us without the cooperation of the countries with their heads in the sand. Sequestration is a good answer for that.

They’re probably surface plates. They’re used as a flat reference for measurement.

The acceleration is more of a function of the powertrain design in steam cars. If you replace the direct drive drive train with one similar to a ICE car (ie clutch+transmission) you can get the acceleration of a ICE car in a steam car. If you want to keep the direct drive though you would need to have a larger engine and use hook-up and variable cut-off to keep the efficiency of the smaller engine while cruising. Steam engines on the whole are pretty similar to electric motors though in having most or all of your torque from 0 rpm which is why many steam cars were direct drive (I think only the Whites and a few race cars had a conventional layout instead of direct drive).

Doble got pretty close to solving that problem actually. His water-tube boilers were extremely efficient at the time (probably surpassing the contemporary ICEs). He also did some work on a “wet heater” which is a boiler that mixed the fuel with the water, burned the mix, and used the exhaust gas+steam mix for the engine. Doble really pushed the boundaries for steam cars.

That's absolutely doable, though you would have to prevent the inactive props from spinning and/or feather them to reduce drag. I don't really see variable pitch props on these though, the weight and complexity penalty would probably be excessive.

It was a little bit of both.

I fly. During critical phases you should be assuming something bad will happen and prepare for it. At least on the pilot end of things, we don’t like surprises so we put our ducks in a row for when shit goes sideways. The reason planes don’t fall out of the sky all the time is assumption of and preparation for failure. It’s why planes have redundant systems and it’s why our emergency checklists are memorized.

No they can. There are a lot of other brands with similar support like Fendt or Massey. The reason everyone gets JD machines is that for their specific purpose they’re generally the best barring a few niche markets like what Ventrac targets with their mowers.

You wouldn’t be retrained to ignore cues from your senses and trust your instruments. That training happens when you’re young and getting your IFR ticket.

It depends on their source. If they’re washed they need to be refrigerated, and if they’re not they can just hang out at room temp.

You need to be familiar with all of the aircrafts systems in case one fails.

In my experience with my two three wheeled go-karts, having the single wheel at the back is much more stable. I’ve never worked out exactly why that’s the case though.
