What did you learn today? Share it with us!

We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

@til Today I learned that the first Xerox copier regularly caught fire, so they shipped it with a fire extinguisher. https://en.wikipedia.org/wiki/Xerox/_914

Radiation

Hormesis has been observed in a number of cases in humans and animals exposed to chronic low doses of ionizing radiation. A-bomb survivors who received high doses exhibited shortened lifespan and increased cancer mortality, but those who received low doses had lower cancer mortality than the Japanese average.

In Taiwan, recycled radiocontaminated steel was inadvertently used in the construction of over 100 apartment buildings, causing the long-term exposure of 10,000 people. The average dose rate was 50 mSv/year and a subset of the population (1,000 people) received a total dose over 4,000 mSv over ten years. In the widely used linear no-threshold model used by regulatory bodies, the expected cancer deaths in this population would have been 302 with 70 caused by the extra ionizing radiation, with the remainder caused by natural background radiation. The observed cancer rate, though, was quite low at 7 cancer deaths when 232 would be predicted by the LNT model had they not been exposed to the radiation from the building materials. Ionizing radiation hormesis appears to be at work.

I guess it's like "horoscope"?

So yesterday I was talking about vocaloid music to a friend of mine and how only the paid ones are called vocaloids and the free ones utau. So I decided to set up a small showcase of the open source program.

The setup was incredibly simple and the github is very well layed out. After the installation you have to add in whatever singers you need (called voicebanks). I personally went to the official teto website, since they make it very easy.

And this is the end result! Picture of open utau with teto on it

Overall, this was a very fun couple hours learning and I am just peeking into an abyss of musical possibility I am glad that it's available to anyone with a computer.

I was watching this video about a bad sponsorship experience involving an electric scissor product. I didn't know they were a thing!

Hey everyone! I've been building BritChat (britchat.co.uk) — a completely free, no-adverts social chat site for British people across all four nations.

It has live chat rooms (Lobby, The Snug, The Lounge), 15+ British games you can play to earn coins, a daily British content card, Poker tables, a daily wheel spin, posts and private messages, and The British Vault — 74 sections of British culture, history, music and icons.

No sign up needed to try the chat. Would genuinely love to hear what Brits think of it!

I guess it makes sense, but I've never thought of it like that before.

From Wikipedia:

Caesar (c. 1737 (supposedly) – 1852) was a slave who is notable for possibly being the earliest-born person ever photographed while alive, when his daguerreotype was taken in 1851.[1] He was also the last slave to be manumitted in New York.
