  • What's the greatest extent (as in the most amount of time) to which you've eaten something past its expiration date with the food still being enjoyable?

    Jump

  • It is wasteful, the expiration date is very conservative. You can push it 20% or more for sealed, correctly stored items. Just check for signs of rot or mold. Food waste is a serious problem in first and second world countries.

  • Why does Lemmy have such a small image size limit?

    Jump

  • What kind of image is it? Reducing the number of colors in a PNG is usually inferior to JPEG compression. It can be OK for screenshots of texts and simple drawing but otherwise you're better off with lossy JPEG or WebP.

    Some instance admins don't even use the built-in pict-rs server so media cannot be uploaded natively at all.

    Some only allow month-old accounts to post images up to 500 kiB.

    Others leave the limits on the relatively high defaults: 10 MiB per file and up to 900 frames for soundless animation/video, which must be in WebM format and VP9 codec (or it will need to be reencoded, which usually fails because of the short timeout). It's easy to use ffmpeg or HandBrake to create low-bitrate 30-second HD videos that fit but the limits are not visible to users and even the defaults are nowhere to be found in Lemmy documentation, I had to read the source code.

  • Setting up a new laptop - How do I get around needing a Microsoft account?

    Jump

  • Nope, requires using a command prompt and executing the OOBE\bypassnro.bat batch file that does the neccessary registry changes and restarts.

  • Setting up a new laptop - How do I get around needing a Microsoft account?

    Jump

  • This works because there is a bypassnro.bat file in the oobe directory, which modifies the relevant registry entries. If it gets removed, you'll need to find its contents online and type them into the command prompt manually.

    Or use this as an opportunity to learn Linux. It's been very usable for a while. If you're confused by distro selection, try Mint Cinnamon first.

  • Well, you have a lot more experience than I do. I don't think I can provide good advice but the idea of another circuit borking it is interesting, I'd put voltmeter(s) on the supply voltage(s) of the deflection circuit and check for changes.

    Please don't call the unit "CRT", it's weird to read phrases like "when the CRT is apart" because you can't really make a tube work again if it's been apart.

    However, it makes me think if one could smash all tubes in a vacuum tube TV in the vacuum of space or one big glass chamber and have it still working. Or build a monitor into a tube that looks like an overly long CRT but just needs power and video. Maybe even include an IR remote receiver for digital picture adjustment. This is way beyond what I will ever be able to do, though, and there is little reason to make this gimmicky thing that is worse than Philco Predicta (TV model line with CRTs outside cabinets) in almost every way.

  • I assume datasheet websites just have pages for every combination of 3-12 alphanumerics to appear in search results, and then use shitty fuzzy string matching tactics to find "most relevant" items. It would help if they managed to extract package marking codes from datasheets so you can find SOT-23 parts by their 2-3 character codes, or whatever obscure system used by individual IC manufacturers. I think they have resources to make the experience way better but they prefer to turn high profits. Personally, I would not mind trying AI (not neccessarily a LLM) for the data extraction but I'd be cautious and only release it if it is decently reliable (but I know they wouldn't bother with that).

  • Pretty sad that a technical manual for the monitor was most likely created but just not digitized in a way you can find. Intermittent faults are very hard to diagnose. What I would try:

    • I assume you've cleaned the potentiometer, which is also easy to check with an ohmmeter (mind the polarity or desolder it to protect the rest of the circuit).
    • Poke the circuit board with a non-conductive object to find loose solder joints or components with bad contacts inside. If the fault is not mechanical, it might be an overheating component.
    • Try adding a fan temporarily to see if the fault appears later, or use a thermal camera to find semiconductors that might go near their threshold temperature (150 °C for the silicon die).
    • Find points in the horizontal deflection circuit where voltage or waveform changes as the fault manifests.

  • Datasheet websites do that a lot. If it's PDF.js, Firefox's PDF viewer (or a fork of it), I just right-click to "Show only this frame" and it goes fullscreen. It might have shenanigans such as disabled printing but you can press Ctrl+Shift+E and reload to check network activity for what address the PDF is loaded from and save that.

    The worse ones are PDFs that exist only for SEO and contain nothing but keywords and a link to a paywall.
