Amazing mnemonics, thank you for sharing. Do you practice this as a mental exercise, or do you actually need to know the day of the week for a specific date that often?
Not that often, maybe one every couple of months. Usually when someone asks me "are you available at (time) on the 31st?" they actually expect me to pull out my phone and load the calendar app. But it's nice to be able to think "Hmmm, that's a Monday, I have that 9:30 AM meeting every Monday" and inform them "I can't do 10:00, how about 11:00?" without having to pull out my phone. (Then I pull out my phone to confirm that 11:00 AM works).
Where I have used it more often is when I am wondering "what day of the week will Christmas be this year?" or "what day of the week will my birthday fall on this year?". It's nice to be able to work those out mentally without pulling up a calendar app and tapping "next month" multiple times. But even that is a rare occurrence.
I don't know what's wrong with me, but I can't do mental calculations with dates because I always think I'm off-by-one, no matter what.
I prefer to "move vertically" in the month. Knowing that 1=8=15=22=29, using prlin's example for December 25 (sibling comment), I'd go like:
"12 is Saturday, 15 is Tuesday, 22 is also Tuesday, so 25 is Friday."
So, starting from key date (12), moving to "the 1 column" (15), moving up or down to the closest/easiest date (22), and then finishing from there.
Slower for sure, but easier for me to not lose track. And now having a known day in every month thanks to rmunn's mnemonic, is going to be a huge help.
Just to clarify, I didn't invent this. I don't think you were attributing it to me when you said "rmunn's mnemonic", I think you meant "the mnemonic that rmunn posted". But just in case anyone thinks I invented this, I didn't. I don't remember where I got it from, it was twenty-plus years ago that I learned this mnemonic, but I didn't invent it.
Upon inspecting with developer tools, I was pleased to find that <marquee> supports GPU acceleration. I vaguely recall reading lore of someone refactoring it up to modern standards in chromium a few years back.
Half a year ago, I captured a photograph of a long train of satellites. However, when I navigate to that location using this tool, I don’t see any satellite train present at that specific timestamp.
I wonder if there are other satellites not included in this dataset, or if I should search way further from the location on the map
A lot of the trackers miss the trains because trains occur within the first few orbits after a launch. So if they don’t start recording data until some delayed event, they miss it. I had this problem a lot with live night sky trackers not showing the trains despite me seeing them quite clearly.
> Worse: it's a conversation killer. There's nothing to respond to. Your wall of text suppresses dialogue. They can't reply, can't push back, can't clarify. It's a weapon disguised as helpfulness.
I had a colleague that was typing such long answers (before AI era) to a simple question. It felt wrong, but sometimes I didn't even read what I heard him typing for half an hour. I was a new employee and he was responding to my questions, that's why I asked him sometimes. He was let go after 1 month. One of the problems was also productivity issue :)
I agree with the messaging generally, but unfortunately to fight implicitly unprofessional behavior with a terse response like this would look explicitly unprofessional!
I got into soldering as a child, but never learned how to do it properly. Years later I found this comic-book-style guide somewhere online, which made it quite easy to do without messing it up: https://mightyohm.com/files/soldercomic/FullSolderComic_EN.p...
Important to note that these days you really should use lead-free solder. You'll find all sorts of people going around claiming that leaded is better, but it's really not, and it's not worth the health risk. Your iron needs to be about 20c hotter than for leaded and your solder joints will look dull instead of shiny. If you find lead-free solder to not flow properly to be grainy your iron isn't hot enough.
Still wash your hands after using lead-free solder by the way. You don't want to be eating rosin or copper either.
Copper is an essential trace element for many living organisms, including humans, meaning you need copper to survive. Generally, copper has low toxicity. (That is, unless you have rare genetic defects such as Wilson's Disease)
Lead is nothing like that. We don't need lead to survive, we shouldn't put lead in our bodies. Lead is also known to accumulate in your body (especially your brain). Avoid lead exposure as much as you can.
