Not the GP, but I recall the KeePass password manager using xdotool for its autotype feature. I struggled to get xdotool to work correctly back in 2014 on a Debian 7 personal computer. Not familiar with 'x2x' or 'xev'
Don't agree -w/all this cynicism... (Did I get a programmer's joke to work?)
Your fastest open-cycle resource usage is water. If you can recycle your water, you've got much slower mass-growth per unit of time in free flight. This could make the difference between 8 hour spacewalk capabilities and 8 day spacewalks.
I've wanted to do this myself... Tho as both an armchair engineer and an armchair programmer. If I'd gotten through engineering in university, (and studied programming language design) this would be an utterly tempting idea for me to try. I must have come back to thinking about doing this ten times in the last fifteen years or so. Off the top of my head, scientific models also sound like they might fit with constraint modelling, tho I might be far too superficial in my understanding of both subjects there.
Pegasus (company's first try overall), Antares, all of the Minotaurs, Atlas 3 and 5 might count as new... Epsilon, H-2 (new?), Vega, Ariane 1, 3 & 4... And the Ariane 1 is both totally new on a systems level and an institution's first attempt at building one. Long March 5, 6 & 7.
Of the investor-backed launch startups, I think it's either no company got it first try... or Orbital Sciences counts as making it first try with Pegasus. Not sure if they count as an investor backed startup.
You could probably get even better walk-able integration by connecting together multiple floors worth of hallways, one above the other. That could approach a 3D city a little bit more.
Isn't it rather precedented to do this? In most readings (that I've seen, anecdotally) of Timothy McVeigh's writings, or Hitler's Mein Kamph, people read these works specifically in the framing of a path to the atrocities, rather than in erstwhile debate of normative claims.
Twitter has a mostly negative ROI for me; I wind up having mild panic attacks both when I visit it, and when I'm reminded of it in the rest of my day.
Almost any reminder that people are having conversations there (especially politics / social commentary)... or forming thought about the world there, makes me fear humanity.
Basically I just keep it around since some (like here on HN) think that it's valuable to prove you exist using an established account.
Speaking of which, how learnable is Elm without any HTML familiarity? I more or less gave up on learning it once the (previous) Elm book started piecing together HTML tags in Elm syntax...
(Apologies if this is too much a personal anecdote for HN)
Honestly, this is one of the indicators that forces my distrust of the modern family of social discourse. My own suspicions have a specific conversation in 2012 spooking a few hundred people (online), who lashed out with such odd phrasing that it spread contagiously to whoever they met... And formed the chimera movement we see now.
...I might outright have an alternate history of the entire '10s "Culture War". Or I might have gone paranoid. Of course I can't prove any of it. I'd love an answer to your first question myself.
Similar issue applies on Windows with Visual Studio's C# compiler; Tho in that case it's a terminal with a non-default starting script that adds the C# compiler, so default and that non-default terminal point CSI or CSC at different languages.
Sounds like the errors I got installing spacemacs. I think... I forced it to work by changing the access permissions on a folder that spacemacs itself had created.
While it wouldn't support fuel use akin to fuel burning electrical sources on Earth, there are endothermic methods to pull molecular oxygen out of C02. In addition to the water electrolysis already mentioned, C02 can be partially reduced to carbon monoxide with artificial photocatalytic systems, or solid oxide electrolysis (with electrical input instead of solar input). Electrolysis would be counterproductive for primary energy, but rocketry only needs stored energy rather than primary. Otherwise, plants doing photosynthesis in a greenhouse could use C02 from outside the greenhouse. Photosynthetic production of oxygen would have side effects of useful agriculture, but that would be difficult to set up early in a Mars settlement effort.
The word hypergolic doesn't mean that, but in spaceflight the term refers to a fairly specific group of compounds; Dinitrogen tetroxide and unsymmetrical dimethylhydrazine or monomethylhydrazine (UDMH / MMH).
As an aside, when I played that game I once made an octal data tape, capable of reading 3 bits of state from a single block in the tape (the "loop"). Used three read circuits next to the tape, which allowed it to detect an additional three states; Namely the block could be non conductor, simple conductor, or a piston block facing up / sideways / down. From there, timing data is enough to distinguish a "sticky piston" from a regular one, allowing for 8 different states distinguishable to the read head.
Well, there is Shen. Static typing, I think it can do dependent typing... Doesn't have the affine types of Rust tho. Not sure how it works out to use in practice.
Disclaimer: Going off memory of the presentations myself, not at all an expert, etc.
Ivan Goddard's descriptions of the branch predictor sounds quite simple that I can remember; The predictor itself is completely detached from the compiler, outside of the instruction layout falling into EBBs. A point that (I think is on the Mill forum somewhere) they've said about the prediction algorithim itself, is that they're doing simulations with nearly the simplest known prediction algorithm, and getting something like 90% success rates from that compared to the 98% the state-of-the-art sees. The difference is entirely in what data is carried by the prediction. (I believe this is in the forum thread on Switch statements, referenced in this video) What the predictor stores and delivers as output is the logical equivalent to an instruction pointer, and where in the EBB they exit, instead of a boolean (or an entire exit table). Which is more state, but not replacing the entire state of the processor. And, as explained in this presentation, the impact of having (effectively) an instruction pointer from the branch predictor is you know what to prefetch from memory. And that pointer, being associated with some other EBB that the predictor might know about, is also enough to ask the predictor for the next prediction, get a second prefetch, and so on.
That also has implications to a point Goddard made in this presentation, in that some entire Switch statements have only one "EBB" (although that's loose terminology itself), and thus only one prediction associated with it. The prediction is to where the block will exit, not whether any specific prediction will succeed, thus there is no case where the processor will stall multiple times before finding the correct control flow. It can only fail once before it determines the correct exit to the block (in general, at least...)
Which is I believe how they are expecting good results, rather than anything peculiar about how they determine the prediction from history.
Edit: I suppose I could note, some of the Youtube personalities who (I have heard) supported the movement are currently staunchly anti-feminist. I'm not certain how central they were to the movement at the time, but they may be relevant to the comments others have made involving the impact of the group.
