I did a little digging and it seems like there’s a tiny kernel of fact at the core of this giant turd of a hype-piece, and that is the fact that they electrified this little spur line from Berlin to the new German Tesla factory by using a battery-electric trainset. Which is not a terrible solution for electrifying a very short branch line that presumably doesn’t need frequent all-day service, even if it’s a bit of a janky approach compared to overhead lines. But hand that off to the overworked, underpaid twenty-two-year old gig worker they’ve got doing “editing” at Yahoo for two bucks an article, and I guess it turns into “world-first electric wonder train amazes!”

For a second, though, I read the headline and wondered if Musk and co. had finally looped all the way around to reinventing commuter rail from first principles after all these years of trying to “disrupt” it with bullshit ideas like Hyperloop and Tunnels, But Dumber.

A combination of resting on their laurels during AMD’s lost decade, and failure to retain competitive process technology during the extended gestation and ultimate failure of their non-EUV 10nm node. The arrogance of taking their foot off the gas and assuming nobody would ever catch back up to them backfired hard.

The reverse. OceanGate saw how planes were being built and said, “let’s do that for submersibles!” even though in airplanes, composites are subjected to <1 atmosphere of tension loading and <2g aerodynamic loading, whereas their submersible was going to be subjected to >400 atmospheres of compression loading, and a much more corrosive environment.

Composites in aircraft have a fairly long and uncontroversial history, and there’s nothing inherently wrong with them in that application. The biggest problem with composites is what happens with them at the end of their service life. Finding ways to recycle them without compromising safety is a good thing, and if it weren’t for Boeing having such a damaged reputation at the moment I think nobody would bat an eye.

The average American house on a basement will have something like 40 m^3 of concrete in its foundation. If all of it could be utilized, that’s still ~12kWhr of storage capacity. Nothing to be sneezed at.

Any time you see perovskite-based cells mentioned, you can assume for the time being that it’s just R&D. Perovskites are cool materials that open up a lot of neat possibilities, like cheaply inkjet-printing PV cells, but they have fundamental durability issues in the real world. When exposed to water, oxygen, and UV light, the perovskite crystals break down fairly rapidly.

That’s not to say that the tech can’t be made to work – at least one lab team has developed cells with longevity similar to silicon PVs – but somebody’s going to have to come up with an approach that solves for performance, longevity, and manufacturability all at once, and that hasn’t happened yet. I imagine that when they do, that will be front-and-center in the press release, rather than just an efficiency metric.

This is actually becoming somewhat commonplace. For example, in many cutting-edge cancer therapies, blood is drawn from the patient, processed in tissue-culture suites on site to extract the patient’s immune cells and sensitize them to some marker expressed by their specific cancer cells, and then the modified immune cells are returned to the patient room and transfused back into their bodies. It’s not cheap per se but it’s something that most top-tier cancer centers can do, and to do the similar process of extracting stem cells, inducing them to transform into pancreatic islet cells, and transplanting those into the patient’s pancreas isn’t that big of a jump – and it’d be cheaper than a lifetime of insulin in any case. It also points the way towards treating other kinds of organ failure without the risk of rejection, too.

Data center cooling towers can be closed- or open-loop, and even operate in a hybrid mode depending on demand and air temps/humidity. Problem is, the places where open-loop evaporative cooling works best are arid, low-humidity regions where water is a scarce resource to start.

On the other hand, several of the FAANGS are building datacenters right now in my area, where we’re in the watershed of the largest river in the country, it’s regularly humid and rainy, any water used in a given process is either treated and released back into the river, or fairly quickly condenses back out of the atmosphere in the form of rain somewhere a few hundred miles further east (where it will eventually collect back into the same river). The only way that water is “wasted” in this environment has to do with the resources used to treat and distribute it. However, because it’s often hot and humid around here, open loop cooling isn’t as effective, and it’s more common to see closed-loop systems.

Bottom line, though, I think the siting of water-intensive industries in water-poor parts of the country is a governmental failure, first and foremost. States like Arizona in particular have a long history of planning as though they aren’t in a dry desert that has to share its only renewable water resource with two other states, and offering utility incentives to potential employers that treat that resource as if it’s infinite. A government that was focused on the long-term viability of the state as a place to live rather than on short-term wins that politicians can campaign on wouldn’t be making those concessions.

Problem is that if you’re looking for FOSS software outside of the absolute most mainstream use cases, that type of software is the only available option. GIMP and Inkscape have been mentioned but throw FreeCAD into the ring as well. Shotcut and Kdenlive are passable, but don’t quite measure up to the commercial alternatives.

My particular hobby horse is CFD code. OpenFOAM is fantastic from a technical standpoint, but until recently, to actually use it you either had to buy a commercial front-end, or literally write C++ header files to set up your cases. There’s a heroic Korean developer who’s put together a basic but very functional front-end GUI in the last year to change that, but it only covers relatively straightforward cases at the moment.

On the one hand, I agree with you that the expected lifespan of current OLED tech doesn’t align with my expectation of monitor life… But on the other hand, I tend to use my monitors until the backlight gives out or some layer or other in the panel stackup shits the bed, and I haven’t yet had an LCD make it past the decade mark.

In my opinion OLED is just fine for phone displays and TVs, which aren’t expected to be lit 24/7 and don’t have lots of fixed UI elements. Between my WFH job and hobby use, though, my PC screens are on about 10 hours a day on average, with the screen displaying one of a handful of programs with fixed, high contrast user interfaces. That’s gonna put an OLED panel through the wringer in quite a bit less time than I have become used to using my LCDs, and that’s not acceptable to me.

Look, some of us old farts started on Linux back before nano was included by default, and your options for text editing on the command line were either:

1. vi/vim, a perfectly competent text editor with arcane and unintuitive key combos for commands
2. emacs, a ludicrously overcomplicated kitchen-sink program that had reasonable text-editing functionality wedged in between the universal woodchuck remote control and the birdcall translation system

Given those options, most of us chose to learn how to key-chord our way around vim, and old habits die hard.

My first attempt to switch to Linux for my primary desktop was in 2007, and ended when my attempt to run WoW via WINE mostly worked, but had a weird an completely unfixable audio delay.

Proton (and Valve’s efforts on SteamOS and the Steam Deck more generally) have been an absolute godsend for Linux as a usable daily-driver.

I remember some of these discussions around the time of the Twitter and Reddit exodii and the mindset of many of these folks was essentially that they’d used this social media protocol to create a nice, quiet safe space for like-minded tech-savvy queer leftists, and felt that the explosion in interest threatened to expose their posts to people outside of the community that they had come to know and trust – which is a point of view I can understand, but as a counterargument, you’re on a public social media platform, and specifically one that is designed to spread content broadly and indiscriminately to servers outside of your control. If you wanted to keep things out of the view of the larger Internet there were other, better solutions for a community platform that you probably should have picked instead.

But it did give us a damn fine concert movie from Muse, and that’s indisputable.

I mean, neither was he, and given that the Saudis bankrolled his purchase and he’s apparently reduced the value of their investment by half, you have to wonder what he’s giving them that has saved him from a one-way trip to a Saudi consulate.

I mean, you don’t really have to wonder that hard. But still, somebody loses you multiple billions in an extended ketamine-fueled rampage, you start to wonder if you should make an example of them…

No… the point I am trying to make is that whether a position can be described as “radical” depends on the larger social and political context. Supporting communism was a radical position in Russia in 1915, but in 1925 it was mainstream. Supporting the monarchy was a mainstream position in France in 1785, but in 1793 it was dangerously radical. You can’t just arrange every political ideology that’s ever been imagined on a chart and then declare them “radical” or “mainstream” simply based on how far away from the center of the chart they are, because what’s mainstream (and how far away away from that you can drift without being seen as an extremist) depends on the larger sociopolitical milieu.

On the contrary, I think your information bubble is pretty limited if you think that a social-democratic position isn’t on the leftward fringe of the Overton window in America, where large parts of the political spectrum believe “the invisible hand” obviates the need for market regulations, and even the most basic and punitive of social safety-net programs get tarred as “communism!” by the mainstream right.

Oh no, they’re merely quite radical in the context of US politics, or mainstream leftist in the context of Scandinavian politics! You’re right – they must be shunned and mocked for this, that’s a surefire way for a fringe group to win hearts and minds…

I was a longtime Debian/apt diehard but I’m coming down on the same side of late. My homelab runs Proxmox (Debian based) with Ubuntu 22.04 LTS containers for more up-to-date packages, but my attempt to use KDE Neon (Ubuntu-based) for my desktop PC was a disaster. I’ve switched to Nobara (Fedora-based), and other than having to switch from Wayland back X11 because Wayland on NVidia breaks a bunch of things I need for work it’s been relatively smooth sailing.

For some the optionality of it is less important than the notion that if it’s performative, you can be bad at it and therefore make yourself an acceptable target for abuse, and besides that the idea that some roles can be restricted to only those with a certain set of physical characteristics is deeply ingrained in many, be that in terms gender, career, or what have you.

I make $115k per year, my wife makes another $20k or so, we have one kid, a tiny house in a slightly sketch part of our Midwestern city that I bought a decade ago when it was almost cheap, and both our cars are paid off… and we’re treading water financially. I don’t know how anybody my age is affording big houses and new cars, unless it’s just by snowballing debt at an alarming pace. I’m already underfunding my 401k just to maintain some liquidity.
