I am still itching to realize an old project idea:
Around here, radio controlled clocks pick up DCF77 signals, broadcast from Frankfurt am Main at 77,5 kHz. We are so far away, signals so weak that it really doesn't take that much to drown them out.
High quality sound cards are capable of handling a sample rate of 192 kHz. That is enough to generate a 77,5 kHz sine wave. Pick the right stereo amp, and at least it claims to handle a frequency range to 100 kHz or even more. The DCF77 signal format is slightly more complex than morse dih and dahs, but not much.
Assume that I make a small program on my PC to generate an output on my sound card which is a 77,5 kHz signal formatted similar to the DCF77 time signal, but maybe off by an hour or two. I feed the signal into my stereo amp, and hook up an antenna wire to the speaker output. The wire could be stretched out in my attic; wood walls wouldn't dampen the signals that much.
I'd be curious to see if I could confuse the radio clocks of people in my neighborhood. I don't know how common such clocks are around here, but you can buy them in lots of different stores.
I believe that is is this simple, given a good sound card and a modern amp: All it takes is to write a small program to generate a properly formatted 77.5 kHz DCF signal. That shouldn't be too hard.

If your computer's clock is way off, and you try to sync it with an internet time service, Windows just refuses to synchronize. You have to add the /force switch on the command line (well, Windows 7, don't know for different versions).
So, such an obvious hacking as shown in the example would not be accepted. But with the microseconds wankers at the stock exchange, a small hack may be devastating.
C'mon, just do it!

An report from Skillsoft finds that 54% of IT decision makers say they have openings they can't fill, and more than a third say they have three or more positions that remain open. So 1 in 4 teams are dreaming?

Visual Studio’s shift to 64-bit means your builds in Visual Studio 2022 will run in a 64-bit MSBuild. This will not cause any problems for most people. However, if your build includes a task that is 32-bit only and does not correctly mark itself as a 32-bit task, your build may fail. Mo' bits, mo' problems

You have a number of Newsletter Topics selected in the Email tab of your account.
If none of these match a tag on the content available for the day, then we don't send you the Newsletter as it would be empty.
If you just clear the Newsletter Topics, then you will get everything, within reason.

Ok. I guess it's the topics, but fwiw, it seems like I've never (?) not gotten the newsletter and it just happened again today.

Quote: I’m a little teapot
Short and stout.
Here is my handle,
Here is my spout.
When I get all steamed up
Hear me shout:
Tip me over
And pour me out!
I’m a very special pot
This is true.
Here’s an example
Of what I can do.
I can change my handle
And my spout.
Tip me over
And pour me out!

Offtracking a little:
Is the 'teapot' game, or pastime, known around the world? My late mother taught me when I was a kid. I never met anyone else who are familiar with it, but lots of people think it is a nice pastime eg. when we are gathered by the fireplace.
It goes like this: The guy starting off chooses some common word that has several different meanings (the more, the better!) and starts talking around it. He doesn't use the chosen word; he rather says 'teapot'. As he talks, gradually the others will think that they know what the 'secret' word is, and join in the talking, using 'teapot' to refer to the term. The more talk, the more people get it. The last one to get it, to understand what the teapot is, gets to start the next round, with a teapot/word of his choice.
Say, the starter picks the word 'ball', telling that
"For this teapot, you'd dress up".
Another one may ask "Is it political?" (thinking of 'party').
"No, but I guess you have it - a couple of teapots".
"Is it under your foot?"
"Yes, it is."
"Do I have a teapot?"
"I saw you playing with a teapot the other day with your son, a rather big one."
"Yeah, a very colorful one. A beach teapot, right?"
The last speaker obviously got it, and may add further remarks about teapots of different kinds. The more 'skilled' you get in this game, the more clever you will be in disguising what the teapot really is, and mixing different interpretations of the term to confuse those who hasn't yet got it.
I guess this game is mostly for people who love playing with words and language. I have a number of friends of that kind.
Don't ask me why 'teapot' is used as the placeholder for the secret word. I have no idea!

If you reword your job advertisements to remove this $TECHNOLOGY as a “requirement” and replace it with a “desirable” (or just mention you use it) you will find yourself able to get more, better candidates into your hiring pipeline But what if you really need 15 years experience in that new JavaScript framework?
