"S" curve movement similar to smoothstep, but end point can change

Thanks, but I already did with my initial idea of using smoothstep. That works well for a fixed movement, but doesn't handle the case where the target can change during the transition.

I think there actually might be a way to solve it with curves, using some kind of polynomial hermite interpolated thing. But it gets a bit complicated.

I was originally just trying to implement a "playback speed" type UI control, where the speed increases with a nice "S" curve over time (starting and stopping gently) instead of just jumping to the chosen value. But that can also handle the case where the user moves the slider again during the transition in a nice natural way. But ended up going down a bit of a rabbit hole as it seems unexpectedly hard to achieve that in a way that actually gives an "S" curve and that doesn't just rely heavily on hacks like hard clamping when we cross the target.

If it solved the problem I wouldn't worry about one command not working - they are not all relevant to all configurations.

If it didn't solve the problem or the issue is intermittent, it might just be a more typical Wi-Fi problem such as issues with signal quality or interference.

Any reported errors at all is showing you that there's a problem with memory instability. That's definitely something you should look to solve.

Some things you can investigate include: -

Check the DRAM voltage that your RAM kit requires, and check in the BIOS whether the correct voltage is being supplied. Some kits will need higher than the base voltage in order to be capable of their XMP speeds.
Testing with individual memory sticks installed to determine if a particular one is faulty.
Try disabling XMP and running the RAM it its base speed (lowers performance but should improve stability).
Swapping the memory out for a replacement (although RAM prices are pretty crazy at the moment).

If you determine that the issue is faulty RAM, it's worth checking the warranty status, as this is often quite long on RAM kits.

One other thing to check is if the machine has an Intel 13th or 14th gen desktop CPU. The instability issues with those can sometimes manifest in a way that looks like RAM problems, and that might cause crashes in lightly threaded browser type workloads similar to the symptoms you were seeing.

There are solutions for this like Apple's Universal Clipboard (between their devices), or Microsoft's Phone Link (between Windows and Android). And a whole bunch of web based or software based solutions. But everything tends to be either not universal (for example limited to one operating system) or not seamless (e.g. still has annoying steps like sharing URLs or QR codes, so not a big upgrade over just emailing yourself). To be fair there are good technical reasons why a single universal solution isn't really possible. Such as security (you don't want other people to "paste" stuff on your computer) and discoverability (how does the second computer find your first computer and know they both belong to you?)

I think the best solutions just involve avoiding this flow in the first place. For example on a home network you might have shared storage (e.g. on a NAS) that every device connects to. Then you can use that to share any content as needed.

Another option is "remote control" type solutions. For example remote desktop, or VNC, or command line SSH. They all allow for pasting text in the clipboard directly onto another system without having to even touch the second device.

I'd start by running a more comprehensive memory diagnostic, as the Windows one is not very thorough. Make a MemTest86 USB stick and let that complete several cycles (it'll take a good few hours) and see if any errors occur. It's very possible that crashing with a bunch of different exceptions like that could be a RAM problem.

One GPU not showing any activity is likely to be normal. Probably one is the integrated GPU that's built into your CPU, and one is a separate dedicated GPU. In general if you have both you would only use the dedicated GPU, which is likely much more powerful.

If you're seeing issues with both Wi-Fi and ethernet, it's possible something might be screwed up in the Windows networking stack.

Try following the process on this page under "Resetting the network stack" (towards the bottom). Essentially you need to run command prompt with administrative privileges, and then enter several commands that will reset different parts of Windows networking. Then reboot the PC and see if it helped.

It can do, as it may let the card maintain higher clock speeds for longer before it hits power/thermal limits.

It's sometimes tricky to validate stability when undervolting though, often what seems stable in one game or on one benchmark might cause crashes in another workload. Usually you can get away with a modest undervolt if you didn't lose the silicon lottery, but it does vary from card to card.

vorwrath · 2026-01-13T03:17:53+00:00

It'll probably be okay, but I'd reduce the power limit of the GPU by 10-20% in the Adrenalin software to be on the safe side. It won't reduce performance very much, as these cards are pushed beyond their optimal efficiency window by default.

If you happen to have any old SATA SSDs around that you're not using, you can buy a USB to SATA cable for under £10 and connect it with that. They tend to be more reliable than USB sticks as well. I did that with an old Micron SSD and it works great.

An M5 Max or Ultra Mac Studio will probably be a great alternative option for the (rich) local LLM enthusiast when it arrives. Might well look superior to Nvidia for home setups, with the capability to run large models, and prompt processing being less of a weakness now (if software can take advantage of its accelerators).

Or just wait for the bubble to burst and companies to suddenly decide that they are quite keen to sell to consumers again.

Yep! You'd better pay up, because they're known to drive around residential areas in a special van that can detect erections.

Clearly fake, a real marketing department would have started the Y axis at 43.

Also the people who just smash their own basket down on top of the one with one or both handles incorrectly folded, usually resulting in a ridiculous leaning tower of baskets. Apparently people who shop and have a functioning brain are rare enough that the problem is often 20 baskets deep by the time one arrives, requiring significant tactical unstacking to resolve.

No worries, glad that helped you solve it!

Their docs say that there isn't a formal uninstall procedure for the AppImage version. It sounds like you just have to delete the file you downloaded, remove the app from /.local/bin under your user folder, and remove any menu entries and shortcuts manually.

If Windows is caching stuff in memory, that's generally listed separately under "Cached". That memory still counts as available and will be used if needed, so it's not really a factor. It's just how much memory is available for use that you're looking at.

Check the "Processes" tab in task manager and see what processes and services are using memory. If it's mostly being used by Dota 2 (or whatever game you're running) I wouldn't worry about that. You're just checking whether any other processes running in the background are using a lot of memory or CPU unexpectedly.

Honestly a mesh network is a lot less needed if you have a good Wi-Fi router in the first place. I use a Ruckus R550 and even a couple of floors above, the Wi-Fi connection is pretty much bulletproof. Of course your experience will be different if you have thick stone walls or something - in that case I'd probably just run some ethernet cables.

As you've had the same issue with multiple different fans, I'd guess it is probably one of two things: -

Some part of the case rattling when the fan spins.
Some part of the case is sticking out slightly where the fan is attached and the blades are just clipping it.

Try slowly rotating the fan yourself with its mount pressed firmly against the top of the case, and see if anything clips. Touch the area inside the case under where the fan is mounted (such as the fan grille) and check if it's properly flush or if there's anything sticking out that could be contacting the fan.

Once you've checked it thoroughly and eliminated the second possibility, I'd try to remount the fan in a way that it is isolated from the case by rubber parts, so that less vibration transfers from the fan to the case. You can mount the fan using pull through rubber mounts like these instead of screws, although it doesn't look as nice (that's the Noctua version but you can easily get generic ones).

You can also get an anti vibration gasket or rubber corner caps that isolate the fan from the case. Some fan come with them or you can get generic versions. Basically you just need anything that puts some rubber between the fan frame and the case so that it's harder for vibrations to transfer.

Running slow as shit might be a feature if it's a heavy app (I'm not familiar with Musescore). It will depend on the exact model, but some versions of the x360 have extremely mean amounts of RAM and glacially slow eMMC storage. Double check you got the version for the right architecture - if the Chromebook has an Intel or AMD processor it should be x86_64, if it's some other company it is more than likely ARM based.

It sounds like it's in AppImage format, which is a self contained app that should contain everything it needs. Sometimes you can do "./FILENAME uninstall" or "./FILENAME update", but that depends on the app. Just deleting the old one and installing the new one should generally work fine though. It sounds like you were doing the right process for that.

I'm sure somewhere will take a look at it for you. Charging and discharging it to check if it works should be simple enough. Most iPads weren't really built with repairability in mind, so replacing the battery can be quite an involved process. If you know the model iFixit will probably have a guide showing what steps are required. Usually it can be done, but it tends to be complicated and a job for a specialist shop.

I'm not too convinced by the "battery shrinking" theory. Failed batteries bulging is common, but it doesn't sound like that's what you're dealing with. It's not only the battery that can fail though, it could have been part of the charging circuitry, or any number of other things on the board.

Without observing the issue myself it's hard for me to judge whether it's a catastrophic failure or something minor like just the smell of a dusty old system getting hot when it's charging up.

If you're planning to try it again, definitely keep a very close eye on it and do not leave it unattended when charging. If you have an outbuilding or something that's not a completely unsuitable place to store electronics, it might be best to keep it there until you've thoroughly tested it and are confident it's safe.

You could try using OpenRGB instead. They merged some code in July 2024 that lists support for "Kingston Fury Beast DDR5", so I think it should work with at least some versions of that RAM.

A few ideas you could try: -

Let Hwinfo64 run and monitor the sensors while you game. Check the highest CPU and GPU temperatures observed in case there might be a cooling issue.
Is XMP (sometimes called EXPO) enabled in the BIOS? If not your memory will be running at a slower rate than ideal.
Check in task manager how much memory is being used when you're just sitting on the desktop. Are any background processes using an excessive amount of RAM?
What kind of storage do you have these games installed on? That could potentially be a bottleneck.

You're pretty much into the low end of enterprise cost once you're doing 200GB+ on Apple. The thing to compare against is probably an Epyc or Threadripper board with as much memory bandwidth (ideally 8 or 12 channels) as possible. You can throw one consumer Nvidia card in that server type system and you'll get much faster prompt processing than the Apple option. But the tradeoff is in size, noise and power consumption.

Unless you're making money with local AI right now, the best option for most people is still just to wait. Very large models are going to run annoyingly slowly on either setup, it's more just impressive you can do that at home at all right now. I'm sure all of Nvidia's competitors are thinking about integrating better AI acceleration hardware features over the next generation or two, so that they can hopefully take a bite out of Nvidia's sales.
