  • I know what hertz is, I’m en electrotechnician. The display’s refresh rate is measured in hertz, and has to be at least 40 Hz or you suffer from headaches and some from photosensitive epilepsy. (edit: only applies if the screen goes black between refreshes, which I just learned OLED, unlike CRTs, doesn’t.) Ideally 100 Hz or more. But the image (frames per second) does not have to change that often. For example, movies are 24 fps but 35mm film projectors are 72 Hz: they flash each frame 3x before advancing (using a three-blade shutter) because 24 Hz is seizure-inducing but using a unique picture for each refresh (72 fps) is expensive. Similarly, your OLED TV is 144 Hz when gaming at 144 fps (if you can afford that), when watching a 60fps gaming video or 24fps movie: the screen controller works the same all the time but the picture it’s fed changes more or less frequently.

    If an OLED screen refreshed at 1 Hz, you’d see a line going down the display edit: I learned about TFT OLEDs which don’t do that. So it never goes below 60 Hz. However, the phone can reduce animation fps when the CPU can’t keep up or to save battery. 1 fps is extremely choppy though, I don’t know where OP got that. I did once use a phone capped to that framerate (via adbcontrol pre-Lollipop where the screenshot is transmitted over USB) and it was awfully non-responsive.





  • Around 2010 but cheap. I still use it though, the browser built for 2G has very low data usage that goes well with my free 1 MB/day plan (mobile data is expensive in my country). The most annoyingly limiting factor right now is SMS memory (around 50 and just 1 draft that gets lost if it gets full), so I got in the habit of deleting every 2FA code etc. as soon as I use it.

    By the way, Nokia 3410 (2001) had like 1 MB of user flash, but still only about 30 events and 100 messages because the “partitions” were fixed, and 20 Java apps (up to 50 kB each) was somehow more important than 10 000 events and 5000 messages. Most users would welcome the latter of course (plus a search feature, it gets tedious with the buttons if you have 100 and only see the sender and ✉️/📂/📨 icon in the list).

    I don’t like computers judging me. Do the job, don’t get in the way. I once had a feature phone where the calendar greeted me with:


    Today

    Your calendar is quite empty! Would you like to add an event?


    No, clanker, I don’t have anything here today because you can only remember 30 events and have been replaced with paper. Shut up and show me the what day of the week the 25ᵗʰ is.



  • So do CDs. 💿 If you have a player with a see-through lid, you can see the disc rotate around 2.5 times slower on the last track of a near-74/80-minute disc as opposed to the first. This might not apply with modern (2000+) and/or portable ones with cache (ESP) − MP3 support is a good clue it has the advanced electronics for that. And yes, CDs’ track starts at the center to enable shorter, smaller disks.

    Players regulate the motor speed based on the data clock (and burners too: there is a pre-recorded “timing” signal even on blank CD-Rs) so technically, a constant-angular-velocity CD could be pressed and played on most players, just with no real benefits.







  • PLEASE don’t criticize OP for asking what you might see as an insensitive question. I don’t think they have bad intentions and they should be commended for seeking explanations.


    I also used to be ignorant or skeptical about gender, back when I was a Christian. But I think you can figure it out like I did.

    Basically, trans rights mean that gender is no longer purely about biological sex (and now we know even biological sex isn’t binary, look up intersex people). And gender isn’t really scientific, it’s how a person feels and presents.

    If you spend time around queer people (online can be enough) and listen, you’ll develop an understanding of different perspectives on gender. These spaces are meant to be safe (that kind of warmth dragged me in) but therefore please refrain from confronting people there. You might have uncomfortable questions but that’s what !nostupidquestions@lemmy.world is for, as opposed to, say, !trans_joy@lemmy.blahaj.zone.

    But yeah, to this day I find some queers’ attempts to make the world more inclusive rather unreasonable, like most neopronouns that have been attempted in the heavily-gendered Czech language.

    Feel free to ask more questions in this thread or privately, I’m sorry that my peers are so unwelcoming.


    Also, you’ve exceeded the character limit so “ir identity, and engaging in transphobia?” got cut off from your title. Unlike on Reddit, you can still edit it on Lemmy.
