  • Honestly, I don’t understand why there aren’t better silent PC desktop cases.

    Or enclosures to put desktop cases in.

    Like, there are people who make generator enclosures that route output through a muffler. That’s a much larger pain in the rear, because there you need to deal with hot exhaust and welding.

    Like, I’d think that I should be able to go get a box to put a PC case in in that looks something like:

    • Sound-absorbent foam on the inside

    • Some kind of heavy frame making up the walls that blocks sound, MDF or something. Sound-absorbent drywall probably isn’t sturdy enough for a commercial project, though some people use it for DIY projects. Ship it as flat-pack, maybe.

    • An array of slow fans with air going to them passing through a 90 degree baffle. Maybe, since now you’ve got no real constraints on your form, put a standard HVAC filter on the intake, keep all the air going to the desktop dust-free and eat up a bit more noise.

    • Some kind of rubber flap affair to route cables in and out of.

    It used to be that one needed physical access to a desktop for putting optical disk media and floppies in, but today, I virtually never touch my desktop, and USB makes it really easy to stick stuff elsewhere.

    I went looking a while back, and AFAICT, there are basically two camps:

    • Large, high-markup rack enclosures aimed at people doing pro audio work, who have a whole cabinet of gear.

    • DIY things.


  • hibernating to disk means all my shell sessions and anything else disconnected anyhow.

    If you can run tmux on the remote system, can manually reattach when you reconnect.

    If you use the UDP-based mosh instead of the TCP-based ssh — it uses ssh to bootstrap auth, then hands off to its own protocol — (a) the system can use local prediction in some cases, leaving it feeling snappier, but also (b) the thing will automatically reconnect and resume sessions. I mostly find it useful on flaky/slow links, but it is also kind of neat to just close a lid, and then pop it open again days or a week later and then just resume working without any user-visible disruption.

    I normally use mosh in conjunction with tmux, since with mosh alone, there’s no way for another host to reconnect to a mosh session…but another host can connect and take over a tmux session being run by a mosh session.


  • suspend has to keep supplying power to the RAM

    When I close my laptop’s lid, I have it set up to suspend for five minutes, then hibernate.

    That lets me close the lid and move the laptop to somewhere nearby without using much battery power, but if it gets left closed for long, the thing will hibernate, so it won’t drain the battery.

    That’s HandleLidSwitch=suspend-then-hibernate in /etc/systemd/logind.conf, and HibernateDelaySec=300 in /etc/systemd/sleep.conf.

    Any other system just gets shut down.

    EDIT: Note that I don’t believe that this is necessary to avoid data loss. I think that the default on Debian is to suspend, but there’s another default to hibernate when the battery becomes extremely low, so either way, a laptop sitting on a shelf for a week — or however long it takes to drain whatever battery is left while suspended — should wind up hibernated. But with the defaults, it’s going to have a laptop with critical battery next time you open it up, and with my settings, it’ll have about as much charge as when you closed the thing.



  • I am quite sure they also don’t offer USB ports to charge the phone you run in lieu of a build in system

    I definitely read an article somewhere where it says that they provide USB power for the tablet/phone.

    kagis

    This article has it:

    https://www.roadandtrack.com/news/a64580484/slate-truck-ev-pickup-truck-suv/

    The Truck will come with a phone mount and convenient USB power to mount your phone or a tablet to the dash.

    EDIT: I think that a better criticism is that this thing is just a prototype, still almost two years away from mass production, assuming everything goes right for them. Like, they could have any number of things go wrong (the Trump tariff situation, for one…hard to have any idea where things will be). It could be that they crash into problems trying to get mass production going. It could be that they can’t hit their target price point.





  • From my other link, I don’t think that the touch screen is an optional purchase. I don’t think that they’re selling any entertainment computer to have a screen on. It says that they come standard with a smartphone mounting point or optionally with a tablet mounting point. But the car computer is bring-your-own, and not built into the car. Which…is what I’ve wanted, because computers age out a lot more quickly than cars do.

    I assume that there’ll be an OBD-II slot that one can hook up to to feed data about the car to the phone/tablet. There’s software that can make use of that. Dunno if there’s any other data typically exposed to car computers other than what that provides.


  • I don’t think that it has a cell modem, either, because it sounds like it eschews a baked-in entertainment computer:

    Roll-down windows come standard, as do manually adjustable rearview mirrors. An audio or infotainment system is noticeably missing, too. Instead, your cellphone or tablet serves these functions, with a dock for the former included and one for the latter available as an optional accessory. Better like the sound coming out from your phone or tablet’s speakers, too, because the Slate lacks speakers, though the brand’s accessory division will gladly hook you up with a set.

    Honestly, if you took my last year of comments complaining about privacy-infringing cars and those complaining about changes to what a truck is, this does kind of look to be addressing both. Gotta see what the actual production vehicle is like in real life, of course, but…

    https://cars.usnews.com/cars-trucks/advice/mini-truckin-returns-slate-unveils-old-school-style-affordable-electric-pickup

    When I say the truck is small, I mean it. At 174.6 inches, it’s about 2 feet shorter in overall length than the 2025 Ford Maverick and Hyundai Santa Cruz. And to use the Wayback Machine to a time when compact pickups were actually compact, it’s roughly the same size as the compact pickups of 1980: the Toyota truck, Chevy LUV and Ford Courier. Notably, no other automakers have offered trucks of this size in America since the mid 1990s.

    Yeah, like the “inexpensive, no-frills utility vehicle” that pickups originally were.










  • They can! We’ve got a nuclear power plant that evaporates water from sewage for cooling.

    https://en.wikipedia.org/wiki/Palo_Verde_Nuclear_Generating_Station

    The Palo Verde Generating Station is a nuclear power plant located near Tonopah, Arizona[5] about 45 miles (72 km) west of downtown Phoenix. Palo Verde generates the most electricity of any power plant in the United States per year, and is the largest power plant by net generation as of 2021.[6] Palo Verde has the third-highest rated capacity of any U.S power plant. It is a critical asset to the Southwest, generating approximately 32 million megawatt-hours annually.

    At its location in the Arizona desert, Palo Verde is the only nuclear generating facility in the world that is not located adjacent to a large body of above-ground water. The facility evaporates water from the treated sewage of several nearby municipalities to meet its cooling needs. Up to 26 billion US gallons (~100,000,000 m³) of treated water are evaporated each year.[12][13] This water represents about 25% of the annual overdraft of the Arizona Department of Water Resources Phoenix Active Management Area.[14] At the nuclear plant site, the wastewater is further treated and stored in an 85-acre (34 ha) reservoir and a 45-acre (18 ha) reservoir for use in the plant’s wet cooling towers.

    If you’re location-agnostic as to your datacenter, though, probably easier to just stick a datacenter by the ocean and use seawater, though. Lots of that.

    EDIT: Or make use of the waste heat instead of throwing it away. If it’s winter and you’re a town in Alaska, say, you’d probably just as soon have the heat piped your way.
