    The most confusing thing is that "200V" isnt a CPU, it's the equivalent of "15th gen".

    The numbers before the V are un-parseable, but at least for the actual parts it's a "Ultra 7 236.1425926V" or something

    Yeah that was my reaction...chip design is the "easy" part of the creation of a new chip, and the fact that it the CPU was of course fabbed in Taiwan is a sign of just how much ground Chinese fabs still have to cover. And relying entirely on SK Hynix NAND and memory says a lot.

  • Current state of Intel 13/14th gen CPUs?

    0x129 (plus turning off XMP) was enough to stabilize my 13700KF for now, and hopefully 0x12B will be the final nail in the coffin for continued degradation.

    However, polling users here for experiences isnt going to give a good perspective on how the CPUs are actually doing. Until it's pretty far gone users may not even notice, and the small sample size of folks who'll reply here is probably not going to accurately reflect the actual state of the CPUs.

    Level1techs has done some really good work investigating this at large scale on datacenters, and the takeaway there is that these problems are going to take a while to show, so its generally not a good idea to buy these CPUs til 0x12B has been out for a few months and we know the effects, at which point Arrow Lake will probably be a better option.

    tl;dr if you're going to buy right now, buy AMD 7000, but if you're willing to wait til February or so, it'll be a decision between the new gen of Intel CPUs and current AMD CPUs (only 9000 series will probably be available by then).

    The molecular mechanical modeller NAMD and its viewer use TCL as the CLI interface, and it's...fine. I would prefer BASH or python, but it works just fine.

    Also Tk is how most LaTeX drawing is dealt with, so trying to modify, say circuit diagrams or chemical structures drawn directly in LaTeX (I.e. chemfig) requires using some Tcl. Again, it's...fine. No huge complaints.

    Edit: bad memory, the drawing program in LaTeX is TikZ not TkZ, its unrelated to Tk.

    I kinda suspect it won't show up as a normal HID keyboard, I had some issues with that with a Razer mouse/keyboard, I think they did some proprietary BS to make sure the shortcuts worked for actions that couldn't be done via keypresses. But I hope it does! It would be cool to see.

    Yeahhhhh thats a pretty niche product and is basically a HID driver interface, so any functionality would have to be rebuilt from the ground up on Linux. It'll certainly take some time, if theres enough interest to make it worthwhile to someone.

    Helium is tiny, and will diffuse though pretty much anything other than continuous welded metal pipe very very quickly. The elastomer seals on a phone would slow it down slightly, but the article's from 2018, before so many phones were watertight. I remember my old iPhone had a little piezo cooling fan in one of the grates on the bottom, so helium would have no trouble at all.

    Can't speak for MEMS specifically, but it absolutely can make chips shut down whole instruments by changing their properties. It intercalates slower, but has much the same effect once it's in there.

    Yup. Most of the mems devices will essentially shut down the device if they go out of tolerance. This is a pretty common-knowledge fact among folks who work with large magnets, or with helium or hydrogen gas.

    Funnily enough, it also happens with equipment microcontrollers which are unlikely to have a MEMS unit in them -- for instance, any benchtop centrifuge made after the mid-90s will shut down, and I'm pretty sure those are still on quartz clocks. It also effects things like on-chip thermometers.

    Sure thats true as long as the basic support on compatibility is there, but as I understand it Pine is so hardware-only that they make it hard for other projects to even support their hardware, i.e. with lacking drivers as the other comment addressed.

    I have my steam games running from a NTFS storage partition separate from my Windows and Linux home partitions...

    I had some initial issues when I started doing that, and it required a different read method for the drive (which never worked), but for about 6mo I've had no issues running steam off a vanilla NTFS drive.

    And there was me thinking that was a mint problem...but it's never broken nearly badly enough to force a reinstall. It's just weird not being able to do a full upgrade unless you temporarily uninstall some packages.

  • To deal with all this Intel CPU disaster, I've been having to manually check MSI's website for mobo updates. It occurred to me that keeping BIOSes and other drivers that aren't delivered through your OS's update manager of choice is such a pain, and it's common knowledge that a lot of critical BIOS updates just don't get applied to systems because folks don't check for updates unless there's a problem. Thinking about that, I realized that it would make life a lot easier if you could just have section in your RSS reader for firmware updates, and each mobo manufacturer published BIOS update announcements as an RSS feed. All your updates are in one place, and you're notified promptly! Of course, this would also apply to NVIDIA drivers, so you can get automatic updates on Windows without having to download Geforce NOW bloatware, but of course that's *very intentional* on NVIDIA's part. Does anyone know of other easy ways to passively keep track of BIOS updates?

    OK, y'all. I'm trying to find a book I read many moons ago. I feel like it was by Diana Wynne Jones, but it's not in her bibliography. Massive spoilers incoming, obviously, but I can't remember what the spoilers are *for*. --- The book starts on an island nation in the south of the world, with a rigid code of conduct which one of the main characters is being disciplined for breaking. The main characters leave on a quest to the oppressive and powerful kingdom in the north, and its revealed that one of the other main characters is the crown prince of the evil kingdom in the north, and can use their magic. If I recall correctly, his use of that magic makes dark veins stand out under his skin, and he has to fight against it controlling him. There's some kind of time limit, I think if he uses the magic too much, it'll take him over and he'll become the new ruler. To gain some advantage over the evil kingdom, they visit an abandoned city, break into some kind of temple, and have an encounter with some kind of deity, which might then take over one of the characters? Later in the story they make it to the evil palace, and there's a plotline about multiple children of the evil king trying to kill this guy, so they can inherit the throne. I think the evil palace is embedded in a mountain somehow. Anyone who can set me on the right track, it'd be much appreciated!
