There are endless specific warnings about specifically opening microwaves, because this exact thinking is what has gotten hundreds to thousands of people killed over the years.
Specifically microwaves, specifically from feeling safe because they have been sitting in a trash pile or basement for months or years.
It happens comically often, to my knowledge it’s the most common specific cause of death in diy.

Sounds like you are talking about the entirety of a small circuit?
If the circuit connects both sides of the capacitor, then it will discharge it. But that means the circuit is discharging the capacitor.If I am, say, putting a capacitor across neutral and live of an ac cord, then I am charging it. Then if I unplug the cord and connect the live and neutral wires, I would be discharging the capacitor.
But … you don’t connect the wires of your plug. They are floating. If one is held at 300V from the capacitor because that was the voltage at the moment I broke the connection, then it will remain at 300V relative to the other forever.Floating is the default state of disconnection. If I rip the capacitor straight out of the running machine, it will be floating and will usually keep its charge for years. If your remaining circuit doesn’t contain something that can drain the capacitor, it will stay undrained.
They absolutely can, that’s why we often put resistors across so they slowly discharge.
The reason we don’t use them as batteries (yet) is their very low energy density. We’d need kgs of capacitors to match a typical phones battery life.

You can verify two textst have the same facts and information, yet one reads way better than the other. But writing a text that reads well is quite hard.

1·18 days agoThe monitor sends you a list of accepted input formats. You can sanity check among the list for any outliers, without online information and without hardcoding limits.

1·18 days agoI’d expect any current displayport port to handle very high refreshrates when the resolution is reduced correspondingly. The limit to my knowledge is in bitrate.
I’d also expect connector support to sit in the gpu driver.A basic sanity-check might be the answer though. Still why not improve it instead of just increasing the number? You could check if the rate is an outlier or there are many profiles offered that climb up to that rate for example.

7·18 days agoIf you measure response curves of individual cones and rods you won’t see any of the parameters go below the ms range, probably not even below 10ms. However the retina does receive bright short pulses as longer averaged signals. All the very high Hz vision cases see information of the same “object” spread over many cells in the retina. A trail showing up as many distinct images vs a long smear.
If you couldn’t move your eyes the limit would be lower, but because you can’t the rendering cannot anticipate those effects and emulate them. Motion blur is what happens when you always “anticipate” the eye to remain static. If you could measure eye movement extremely well and react within well under a ms, you might be able to match motion blur to eye movement of a single person. Add a second observer and it already breaks down. Not that our sensors are anywhere remotely near making this possible.
Edit: I suppose this would mean if you integrated a display into contact lenses and got the latency right you would max out at lower Hz.

3·18 days agoShouldn’t be enums as refresh rates can be floating-point and in practice there also is a lot of weirdness out there, like 59.94Hz.
The timing really needs to be matched to the monitor, you don’t want a 60Hz monitor using the resources of a 1000Hz monitor at any point. It should also be handled by the gpu and gpu driver more than the os.
I don’t think it’s that easy and I struggle to think of a legitimate reason. To me it seems more like an arbitrary bounds-check on monitor info received via hdmi/displayport. Bad coding for sure, but also potentially a point where people are pushed to newer more problematic versions of windows as the older ones “don’t support new hardware”.

71·18 days agoIt really isn’t. There’s a whole lengthy explanation of it here but tldw motion breaks it. Lower refresh rates leave single images instead of smooth trails, while if you track motion then slower refreshrates make stuff blurry while in motion.
I don’t think the video mentions it, but you could flicker the backlight to make tracked motion smooth, but then eye movements will see many individual images end up on your retina instead of motionblur.
If you wanna wiggle you mouse at high speeds while maintaining image quality, say for fps 180 noscopes, then you will easily see improvements into the 10s of kHz.

Global News@lemmy.zip•China’s new language law to criminalise advocacy of ethnic minority rightsEnglish
1·18 days agoI would say if a country wants to swallow a group of people, they should add their language to the official languages.
There are sufficient examples of nations with multiple official languages, like Belgium and Switzerland each having 3.Apply this backwards in time too and it solves the issues.
Don’t wanna add a random language to your state? Don’t annex stuff.
You’re counting technically at war? Then almost no country will qualify. Certainly not the us, which multiple countries gotta have declared war with.

Selfhosted@lemmy.world•What’s the currently best way to manage TOTP tokens?English
9·22 days agoThis. Aegis does all of the points except offsite backups. And for good reason.
The Aegis app has no network permissions at all, which is obviously a massive boost for security and privacy. And besides, off-device backuping is a nightmare.Syncing the Aegis backups made on change to some other server is better handled by a great dedicated app. Syncthing is the best such program (by far), though for the few files involved here nextcloud would work just as well.
I also find it to be very slow on many networks, and even in ideal conditions it might get 2MB/s when the phone has a 10MB/s connection.
For photos and predictable stuff I thus use syncthing, and the odd very large thing I send using scp with termux.
