I don’t know about repeating or being able to have very long playtimes, but I do know the MIDI (.mid) file format can play songs at extremely small sizes compared to mp3 as it effectively stores the sound like music on a sheet which is played by a synthesizer. Also the MOD file format allows samples to be recorded as a sort of blend of synth and recordings.
- Comment on How can I play online chess with limited time per move instead of time per player for the game? 1 week ago:
You could go to lichess.org and create your own time controls. They let you stipulate an initial time and an increment.
For example you could have a game with a 30 second time for each player and then add 15 seconds for each move after that.
I believe the time would be banked for each move rather than a hard fixed limit for each move.
You could then create a custom game open to others, or make the game available by link to a friend.
- Comment on I hate this image because idiots will see it, not understand what its showing, and make up some crazy shit based on it. 1 week ago:
Well, it’s showing the moon lit up while it’s behind the earth, so clearly it should all be dark due to the eclipse. So I can only conclude that it’s trying to get the word out that we actually live in a binary solar system.

It varies by army, so this won’t be exact.
A platoon has around 30 people in it. It has around 20 privates, about 7 non commissioned officers and one commissioned officer. Say 3 lance(junior) corporals, 3 corporals and a sergeant. In overall command is a commissioned officer.
When you join the army you typically go in as non commissioned as a private or commissioned as a leuitenant.
Officers are trained to lead people from the start. The lieutenant may have 1-2 years experience and the sergeant may have 16 years experience.
The next level up is a captain who commands say 3-5 platoons. At the start of saving private Ryan, Tom Hanks character was a captain in command of around 100 soldiers.
I think around 5 companies make a battalion. And that’s just soldiers.
You can also make a unit out of soldiers, engineers, artillery, transport and some other specialists like medical and cooks.
I believe a brigadier general would command a unit around this size.
To get there I would expect he worked his way up the rank, working at each level for around 2-3 years.
He would have been in the army around 15-20 years, but some people could get promoted faster.

If you shoot from cover, some come to find you. Back into corner and rapid fire, not a great plan, but got it on about 6th try.

Rookie Numbers.It only uses elecitrical power generated. Why not cook turkeys in heat destined for cooling towers ? Gotta push those numbers way up.

- Comment on Could a bird propel a skateboard by flapping its wings? 10 months ago:
I reckon a Pelican would easily be able to get a skateboard rolling. I’m just now sure the best steps to proceed testing it.
I’d try a skateboard at the top of a hill and see about getting a cockatoo to somehow get the board to roll under it’s own propulsion so it can sit back and enjoy a ride down a hill. That’d be the way I’d try if I wanted the bird to do it repeatedly.

- Comment on What is a GPG signature? Does it help us stay protected against deep fakes misinformation, and if so, how? 1 year ago:
GPG uses a public key encryption algorithms. Widely known encryption uses symmetric encryption, ie the same passphrase is used to encrypt and decrypt.
Public key encryption algorithms have two keys, a public key and a private key. They are created as a pair.
When someone creates the pair, they can safely widely publish their public key which is essential to encrypt a message to the receiver. But a different key is needed to decrypt the message (the private key).
They can also be used in reverse. A person with a private key can sign a message saying they created a document and it has this hash. We can use their public key to confirm the message they send out has not been altered.
A hash is a computer algorithm which examines a files and creates a short pattern of characters. If the file is changed then the hash of the file also changes.
As a example, If we had a written letter, a very simple hash could be to assign a the number 1, b 2, c 3 etc and full stop could be 27, comma 28, and the digits 0-9 29-38. For every character we keep adding the assigned numbes and keep a total. When we get to the end, we take the last 3 digits and have a number between 000 and 999. (Technically this is more a checksum than a hash, but please just go with it. A hash like MD5 or SHA256 is complex and has ways to detect if the message contents was shuffled that the described hash wouldn’t)
Continuing the example, I may receive a letter from a relative who asked me for some money or something. If I wasnt sure if it was real or not, I could calculate the hash and call the relative and confirm the hash.
But back to your example, there might be a press release from the presidents account saying something like
"Dear constituents, Please find attached a link to download the lastest video update from the presidents. It can be downloaded at URL, and it has a SHA256 hash of abcd12345 Signed President GPGSignature for president@example is ‘ajfuebslch’ " Once we download the file, we can use SHA to generate the has of the file we downloaded and GPG to confirm the signature of the message we received matches the text of the message we received.
If we didn’t have GPG and the Public key of the presidents account, an attacker who makes deep fakes could send us spam purporting to be from them and include in the message the correct hash for their deepfaked video.
I dont quite fully understand how public key encryption works, but the GPG signature allows us to confirm the message was sent by whoever has the matching private key to the public key we’ve got and the hash lets us confirm the file we downloaded is the same as the video the semder wants us to receive.
- Comment on What can i do with an old netbook? 1 year ago:
I would use it as a network attached storage / media player running Linux.
It doesn’t have to be always on, and having copies of photos or important documents would give peace of mind.
Debian, Ubuntu and the raspberry pi os (they have an installer for normal computers, not just pi’s) would be distributions I’d consider with the pi os at the top of the list.
