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.

Thrashy , 1 month ago to Technology in The ugly truth behind ChatGPT: AI is guzzling resources at planet-eating rates

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.

Thrashy , 1 month ago to Technology in Texas power prices briefly soar 1,600% as a spring heat wave is expected to drive record demand for energy

I exaggerate -- but Magic Rock is doing booming business installing strings of natural gas generators at Buc-ee's across the state, and I'm currently dealing with an institutional client who wanted to provide backup power for a satellite campus, and didn't even stop to consider battery-backed PV on the way to asking for a natural gas generator farm.

Thrashy , 1 month ago to Technology in Texas power prices briefly soar 1,600% as a spring heat wave is expected to drive record demand for energy

It's not a coincidence that Texas is a hotbed of development for "microgrid" systems to cover for when ERCOT shits the bed -- and of course all those systems are made up of diesel and natural gas generator farms, because Texans don't want any of that communist solar power!

I've got family in Texas who love it there for some reason, but there's almost no amount of money you could pay me to move there. Bad enough when I have to work on projects in the state -- contrary to the popular narrative, in my personal opinion it's a worse place than California to try and build something, and that's entirely to do with the personalities that seem to gravitate to positions of power there. I'd much rather slog through the bureaucracy in Cali than tiptoe around a tinpot dictator in the planning department.

Thrashy , 1 month ago to Technology in The decline of Intel..

The only link I am aware of is that Intel operates an R&D center in Haifa (which, it happens, is responsible for the Pentium M architecture that became the Core series of CPUs that saved Intel's bacon after they bet the farm on Netburst and lost to Athlon 64). Linkerbaan's apparent reinvention of the Protocols of the Elders of Zion to the contrary, the only real link seems to be that Haifa office, which exists to tap into the pool of talented Israeli electronics and semiconductor engineers.

Thrashy , 1 month ago to Technology in The decline of Intel..

Historically AMD has only been able to take the performance crown from Intel when Intel has made serious blunders. In the early 2000s, it was Intel commiting to Netburst in the belief that processors could scale past 5Ghz on their fab processes, if pipelined deeply enough. Instead they got caught out by unexpected quantum effects leading to excessive heat and power leakage, at the same time that AMD produces a very good follow-on to their Athlon XP line of CPUs, in the form of the Athlon 64.

At the time, Intel did resort to dirty tricks to lock AMD out of the prebuilt and server space, for which they ultimately faced antitrust action. But the net effect was that AMD wasn't able to capitalize on their technological edge, Ave ended up having to sell off their fabs for cash, while Intel bought enough time to revise their mobile CPU design into the Core series of desktop processors, and reclaim the technological advantage. Simultaneously AMD was betting the farm on Bulldozer, believing that the time had come to prioritize multithreading over single-core performance (it wasn't time yet).

This is where we enter the doldrums, with AMD repeatedly trying and failing to make the Bulldozer architecture work, while Intel coasted along on marginal updates to the Core 2 architecture for almost a decade. Intel was gonna have to blunder again to change the status quo -- which they did, by betting against EUV for their 10nm fab process. Intel's process leadership stalled and performance hit a wall, while AMD was finally producing a competent architecture in the form of Zen, and then moved ahead of Intel on process when they started manufacturing Zen2 at TSMC.

Right now, with Intel finally getting up to speed with EUV and working on architectural improvements to catch up with AMD (and both needing to bridge the gap to Apple Silicon now) at the same time that AMD is going from strength to strength with Zen revisions, we're in a very interesting time for CPU development. I fear a bit for AMD, as I think the fundamentals are stronger for Intel (stronger data center AI value proposition, graphics group seemingly on the upswing now that they're finally taking it seriously, and still in control of their destiny in terms of fab processes and manufacturing) while AMD is struggling with GPU and AI development and dependent on TSMC, perpetually under threat from mainland China, for process leadership. But there's a lot of strong competition in the space, which hasn't been the case since the days of the Northridge P4 and Athlon XP, and that's exciting.

Thrashy , 1 month ago to Technology in OLED monitor momentum expected to continue — analysts expect 1.34 million units shipped by year end

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.

Thrashy , 1 month ago to Technology in Ordered back to the office, top tech talent left instead, study finds

Through the course of my career I've somehow lost office space as I've ascended the corporate food chain. I had a private office/technician room in my first job out, then had an eight foot cubicle with high walls, then a six foot cubicle with low dividers, and then the pandemic hit. The operations guy at the last place was making noises about a benching arrangement after RTO, like people were going to put up with being elbow to elbow with Chris The Conference Call Yeller and Brenda The Lip Smacking Snacker while Team Loudly Debates Marvel Movie Trivia is yammering away the next row over.

Hell, if it meant getting a space to myself with enough privacy to hear my own thoughts I might consider giving up my current WFH gig. But everybody's obsessed with building awful office hellscapes and I don't have the constitution to put up with that kind of environment.

It's all Broadwell Xeons. Sure, there's 8000 of 'em, but after you factor in purchase price, moving and storage costs, time spent parting out nodes, shipping costs, etc... I think you'd have a hard time breaking even, and for an end user you can get like 4x the FLOPS per socket at half the power consumption with current server CPUs.

This used to hold broad cultural applicability, back in the Before Times when the "Hitler Did Nothing Wrong" crowd was still excluded from the political mainstream. Norms excluding out-and-proud ethnofascists from official, public participation in the English-speaking political right started to seriously slip around the time of Obama's election and certainly ceased to exist after Trump's win in 2016, but prior to that time "Nazi" was very much more often an ad-hominem attack than an accurate description of somebody's politics.

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.

Frankly, given the conflicting priorities and attitudes of the two primary Lemmy devs compared to the needs of instance admins, I'd rather the better-funded instances pooled some of their excess and funded an independent contributor to work on mod tools, GDPR issues, and other things that operators are concerned about that have been backburnered by the current devs.
