Acoustic propagation. I design large format PA systems and as a result need to know both how to make sound and stop sound at a large scale. It is entirely possible and actually relatively easy to be super precise with where sound goes or doesn’t go. The problem is cost.
How do I subscribe to acoustic propagation facts?
Just message me, you’ll get some!
So a lot of people are aware of active noise cancellation that you find in headphones nowadays, that works in large scale as well. The first time that type of technology was used was in the greatful dead’s wall of sound. The problem is it’s expensive to do large scale.
Imagine a Venn Diagram with three circles:
Ships and their electronics
Linux servers
Industrial roboticsI’m in the middle where all of those intersect. Pays well.
Have you read how to avoid huge ships?
I want that book! But gods, I’m not paying that.
Each one of these recommendations raises more questions that previous one.
Kind of hard in my line of work.
Found the guy who blocked the Suez canal
Its a sea-men-al work in the business
A ship, a Linux server, and an industrial robot enter a bar.
…and the bartender asks: “Is my geophysical survey data ready yet?”
And the industrial robot asks: “Why does a bartender need geophysical survey data?”
Not my question to ask. Whoever pays for the survey gets the data.
Compared to people around me I seem to know a lot about fashion history, textiles and clothing in general.
Hot tip, like literally a hot tip, if you’re having trouble being miserable in the hot weather this summer, try wearing 100% cotton, loose fitting clothes that cover your skin. 100% Linen or a linen/rayon blend is even better but pricey. Wear a hat. Polyester, acrylic, spandex, microfiber, they’re all plastics that not only insulate you but don’t absorb your sweat. That “moisture wicking technology” athletic clothing is always going on about is total bullshit. Wear a linen shirt in the sun with a breeze and marvel at the magic of evaporative cooling. Covering your skin with a hat and sleeves not only helps prevent sunburn, but is also your own portable shade. You know how much cooler it is in the shade, right?
You might look at pictures of old timey people all dressed in big dresses and long sleeve shirts and waistcoats in the old west and think “wow they must have been so uncomfortable!” but I bet you they were more comfortable than you in your polyester. Just ask a reenactor!
I can read UPC, ISBN, and EAN bar codes. Tear the numbers off the bottom, hand me the lines, and I can tell you the numbers you tore off. Also, if you give me any specific date on the Gregorian calendar (on or after October 15, 1582), I can tell you the day of the week it was or will be on.
Finally…way less interesting…but I have a Master’s degree in math and have taught elementary, middle school, high school, dual credit, and college math classes.
You’ve memorised the Doomsday algorithm?
Indeed.
July 26, 6.000.002.024
It’s a Friday. Because all that matters in any date with a year greater than four digits is the last four digits, and July 26, 2024 is today, and today is a Friday. 😊
But, if I didn’t know July 26, 2024 were a Friday…
Step 1)
Starting numbers:
- Century is a multiple of 400: 2
- Century is 100 more than multiple of 400: 0
- Century is 200 more than multiple of 400: 5
- Century is 300 more than a multiple of 400: 3
2024 is in the century of the 2000s. 2000 is a perfect multiple of 400, so the starting number there is 2.
Step 2) 24 is a multiple of 12, specifically 12 x 2. Thus we add 2.
Step 3) 24 is a perfect multiple of 12 with zero years in excess, so we can add 0.
Step 4) There are no leap years in the 0 extra years beyond the closest multiple of 24, so we can add another 0.
Step 5) The Doomsday for July is 7/11. July 26th is 15 days after July 11th. 15 mod 7 is 1, so we add 1.
Step 6) 2 + 2 + 0 + 0 + 1 = 5
Step 7)
- 0 = Sunday (Noneday)
- 1 = Monday (Oneday)
- 2 = Tuesday (Twoday)
- 3 = Wednesday (Threesday)
- 4 = Thursday (Thorsday Foursday)
- 5 = Friday (Fiveday)
- 6 = Saturday (Sixaday)
Our total was 5, so the date July 26th, 2024 (or any year with the last four digits 2024) is a Friday.
What should also probably matter though is the existence of the sun 😉 Otherwise, how can it be a day?
To be fair though, I gave that point in time a day-like notation
I edited my response to show the math behind it. And well played with the astronomy fun, didn’t even notice it. I am a math teacher with autism IRL, so I hyperfixated on the numbers!
I am a steadicam operator and have been making power cables for cameras. I get calls from around the USA and the world from people trying to troubleshoot their electrical systems on their Steadicam and cinema cameras.
I’ve delved way too deep into the fall of the Western Roman Empire. I think I know a lot about Majorian, Stilicho, Aetius and Ricimer. My gf at this point even knows who Honorius is and why he was a bad emperor. Edit: and that he had chicken :)
When I saw the meme “How often do you daily think about the Roman Empire”, I knew that it was about me, because the answer is yes :/
I think it’s neat that you’re taking an interest in history. You could do worse things with your free time :)
Thank you! I really appreciate it. I think so too, especially because learning history provides one with a better understanding and contextualization of current events. I’m still wondering why exactly I picked the Roman Empire, but I also think that’s a pretty nice topic to delve into :)
Once again, thanks for your comment - it really matters to me!
I’ve been learning about air quality consultation as a backup business plan over the past few years. Buying commercial-grade sensors, researching various aspects of air quality, monitoring, and purification techniques. Nothing crazy but feels pretty niche to me.
I’m an expert in consequential greenhouse gas accounting. Which is the sub discipline of GHG accounting that specializes in understanding how policies and decisions impact global GHG emissions.
I don’t know how to articulate an answer to this right now, but I wanted to say that this was a great question, OP — there’s some really cool answered here
I am terrified of your ineffebale, unspeakably niche eldritch knowledge that is so arcane as to be impossible to articulate in human language. I ask only that you let me and my family live when you rise to power as a Dark Lord. We are good followers.
Maintaining old react apps that don’t use setState…
this.state.temp = val;Meanwhile elm programmers: look what they have to do to mimic a fraction of our powers
You have my full sympathy.
Thank you. Right now I’m upgrading our 5 year old react version while forking all unmaintained deps … fun
I lucked out, I’m on a two year project that just wrapped up and we skipped useMemo for the most part. Then it got announced that the new React version will depreciate that.
Good luck dude.
There will be no wrapping up this project in the foreseeable future as it’s part of our main platform. I’m looking forward to moving from cra to vite and removing one ore more of the three css frameworks we are using. The App is also still incomplete as it’s replacing an ancient asp net project still partly in use … so it’s legacy hell over here. Also it’s all class components so … no useMemo atleast for now.
Edit: thanks as well, appreciate it.
- I am a beast at movie and tv themes
- I’m very good at guessing boardgames from just very few clues (bu i think that part of that skill is that people who ask usually don’t ask for the deep knowledge)
- I have a triggerable wealth of knowledge about random trivia facts. During some conversations i will just randomly remember something related to the current topic and then spout it. My goto fact when someone asks me to give some random trivia is that alpaccas have a set of razor sharp teeth between their molars that they use mainly to bite off other alpaccas testicles
Though currently on hiatus, I do HEMA (historical european martial arts) so know a thing or two about swords and swordfighting.
Reggaeton, and the rise of música urbana from around 2005-2015.
Edit I also enjoy learning about Latin American history.
I’m an enthusiast about Mezo American history and Mixtec Pueblo culture pre European contact. In other words I’m an Aztec Fanboy.
Progressive Rock
Oh yeah? Name three of their albums.
That’s a pretty low bar, I know, but as I’m more into ProgMetal, I’m unable to name albums that are actually ProgRock. Well, except Rush, maybe.
