Re: Are binary prefixes REALLY an official international standard?

They certainly are standardized. Yes, the actual standard seems to be not free; perhaps you find this to be authoritative enough: https://en.wikipedia.org/wiki/IEC_60027, or https://en.wikipedia.org/wiki/ISO/IEC_80000, section "Units of the ISO and IEC 80000 series" (edit: I see you had that last l...

You are making no sense at all. The standard is the authoritative source. Yes, the document costs money, most people don't work for free. End of story.
Thank you have a nice day.

Re: Are binary prefixes REALLY an official international standard?

This appears to be the SI standard If I were publishing; I'd define my terminology in my introduction, or an appendix to ensure that there is no ambiguity. This was flagged as an unofficial source in my first post. I don't doubt the accuracy of the webpage; the question is, is this available on an ...

Re: Are binary prefixes REALLY an official international standard?

The IEC standard is named in e.g. the Wikipedia article you linked, and clearly you understand that because you say you do not want to pay for the standards document. So what are you asking for - directions to a public library that has it? :?: I don't care what the name of the standard is; I want t...

Are binary prefixes REALLY an official international standard?

I've been taking the word of books and websites regarding prefixes for digital data sizes, such as 1 KB (kilobyte) = 1,000 bytes, 1 KiB (kibibyte) = 1,024 bytes. Some of them are very well-respected, such as Newton's Telecom Dictionary, but none of them are the official standard source. So last nigh...

Re: Monitor repair questions

I'll just quickly comment that caps do fail with age, and especially the ones in modern power supplies tend to, because the high frequencies involved put a strain on them. Typically these days, you'll have a diode bridge that feeds a single big capacitor, which feeds a couple of switching transisto...

Re: Monitor repair questions

when they start bulging etc, they are "leaking" the stored power that the system relies on for a steady, regulated power source Capacitors which have bulged tops have lost capacity and we now have ripple. the clicking can be caused by the voltage going positive and causing a start-up but not stayin...

Re: Monitor repair questions

Just a quick reply before I head out to teach computing. Fig 10 - do any of those black tube like things with metal tops have bulged tops? If so they need changing. They are capacitors. I haven't scrolled back on your link yet to see make and model - Arrh yes! Acer AL1916. And yes, I've fixed numer...

Monitor repair questions

I got a relative's computer and monitor a few years ago. The monitor would actually be more useful to me since the computer is several years old, so I tried it out. Unfortunately, it doesn't work. I just recently got around to looking at it. I found the service manual here: https://www.manualslib.co...

Is it possible to use my Sony DCR-TRV250 as a USB webcam?

I did in Windows XP, but I can't get any video app to see it. I tried VLC, and under "Open capture device", it had video camera selected at the top, and when I clicked on Play, I just got a black screen. I think it was trying to play video through one of my Oculus Rift sensors. The DCR-TRV250 has a ...

I have to be honest, I don't know what ZEKE is. I wasn't able to figure it out from internet searches. I still have my train set from when I was a kid, though! I apologize, I wasn't extremely clear.

Re: I got a Raspberry Pi. What cool stuff should I make?

I recently got a Raspberry Pi 4 Model B (4 GB RAM), because I wanted to make a media center for my Jeep, but I'm not very imaginative when it comes to electronics projects. So please recommend some cool ideas of projects I can make with it! :D PiHole https://pi-hole.net/ That's a really good idea, ...

Re: I got a Raspberry Pi. What cool stuff should I make?

It depends sort of what you want to do. Keyboard of some sort, a mouse or trackball or touch pad of some sort. keyboard with touchpad? Then some sort of LCD display. There are small car display/monitor devices. Entertainment could then also be used, loaded from a flashdrive. I probably would have j...

Re: Gamma Ray Bursts From Black Holes *May* Exceed Speed Of Light

I've always wondered why galaxies and black holes have discs containing the objects that revolve around them. Why are they almost always a thin disc? Why don't objects get pulled toward black holes from under them or above them instead of always in-line with everything else (a spiraling disc)? Firs...

That's definitely unusual. I like it! :lol: Extra credit if you can identify the tea. Hint: It's from Seuth Efrika. Orange Peko and Peko? In answer to the OP, shouldn't you have investigated what could be used on a Pi before deciding to get it? Doesn't it also use an odd CPU, such as an ARM type? T...

Alta Vista, because that was what h4X0rz used 8), and Dogpile. Back in the late '90s, when I was in high school, the school librarian and IT person seemed to prefer Dogpile over other search engines, so I started using it. For some reason, I thought Dogpile closed down, but after looking it up just ...
