Wow, if there was anywhere to find other people who break down license plate numbers into primes, it's the Dope! Now I feel like part of an exclusive club.

Not all that exclusive; I do that too. But only when I'm really bored.

I like to sew and embroider, but my neck won't cooperate at this time. Damn!

I picked up a silly, stupid hobby to occupy myself while I'm waiting for my pain pill to kick in. I found a coloring app! So silly, so juvenile. Sometimes I even share the pictures with family and friends. For instance, my sister-in-law likes owls, so I select owls to color, then send her the picture.

The app was screwing up on sharing, so now I just attach the picture which is conveniently stored on my tablet. I made the terrible mistake of putting an actual filename on one picture, so that means I have to put filenames on all of them. All 1700 of them...

One of my most satisfying hobbies is writing. No, I'm not published yet. But I am good. Damned good. I'm also a very decent editor. I have just started blogging again after a long hiatus.

And then there's stuff I write that I can't tell you about...

Take (sum of the odd digits) - (sum of the even digits) or vice versa. The original number is a multiple of 11 if that difference is.

Using 3623, (3+2) - (6+3) = -4 which isn't evenly divisible by 11.

Why does it work? Let's take a 3-digit number abc and multiply by 11. Get abc + abc0 = a[a+b][b+c]c as the digits if no carrying. [That's not a product: each bracket contains one digit of a 4-digit number.] Get (a+b+c) - (a+b+c) = 0 which is divisible by 11.

Now if there's carrying, you might get abc + abc0 = a[a+b+1][b+c-10]c = (a+b+c-10) - (a+b+c+1) = -11 which is divisible by 11. Etc. Any carrying will add or subtract 11 to/from your eventual sum.

If you write erotica, you could certainly tell us about that, so that can't be it.

Revolutionary tracts advocating the overthrow of the government, followed by show trials and life imprisonment for everyone over a GS-12? Nah, doesn't seem like your sort of thing, but who knows what lurks beneath the surface?

If it was in the "if I told you, I'd have to kill you" zone, it wouldn't be a hobby, so that's out.

Nah, no idea.

. . . . . . . anybody else occasionally look at a sentence or a phrase, or a group of numbers and check whether the number of characters can be divided up into groups of seven? . . . . . . .

I don't know if this can be considered a hobby, but a few months ago, I set myself the task of running all the streets in my city; I had heard about Rickey Gates, an ultrarunner who did that in San Francisco in 2018, to really learn his hometown. I live in a little 30,000 pop. town of about 4 square miles, so it's not a hugely daunting task. I'm roughly halfway through.

I had thought that it was a pretty original idea, albeit one I had stolen from Gates, but no, there are runners all over the world knocking off every street in their towns; Strava even has a blog for people attempting the feat, and there's, natch, an Instagram hashtag. Still, it's gotten me to parts of my little town that I've never seen before, and it's got me logging a lot of good miles, so I'm enjoying it.

I've attempted something similar, but it involves all the county and FS roads in my county (I cross into other counties and states depending on the road - I live on a state border). Bigger difference is I started it on my dual-sport motorcycle (haven't finished...yet). However, I've now switched to attempting the same thing on my mountain bike. Not sure I will ever finish either (probably not), but it is fun and I've found some great places to go back to and walk with my wife.

Plus, you get advertisements and comics and random content, like notices.
I used to go in to the library when I was in school and get the microfiche rolls of the earliest editions of various newspapers and just read through them. I remember following some pretty astonishing crimes from detection through prosecution over the course of months of the same paper. Boy, if you think we live in dangerous times go back and look at how your grand or great-grand parents lived.
I loved those things (the papers, not the crimes).

The related thing is to run pictures. It takes some preplanning & running w/ a GPS but you run down (& maybe back) on certain roads to create an Etch-a-Sketch like shape from your run/ride - spell out the town name or create a hand/the bird, etc.


It was more to pass the time/keep me focused/potentially catch a hit-&-run driver but I would try to read/say aloud (in military alphabet - Alpha, Bravo, Charlie, etc.) every car/truck license plate that passed me when I'd be out on the bike. Pretty much every state has a 3'/4' rule for passing cyclists & although I have a handlebar cam the cops can't cite the driver if all they have is video of the car making a dangerous pass.

I also do some niche sports, including one that I'd never heard of before another Doper introduced me to it.

Ah, a new math trick! I already knew that a 3-digit number xyz is divisible by 11 if x + z = y, or if x + z - 11 = 0. 4 digit numbers in the form of xxyy and xyyx are divisible by 11. 3-digit numbers in the form of xxx are divisible by 37. 4-digit numbers in the form of x00x are divisible by 7, 11 and 13.

I have my own license plate game I like to play. In North Carolina, most tags have three letters followed by three numbers. I take the three letters and try to make a word that has those letters in that same order. Then I score the word, 1 point for a word with the letters, 4 points for a word with two of the three letters adjacent, and 9 points for all three letters appearing consecutively. Then if the word doesn't start with the first of the three letters, i award myself a bonus point.

So far, my favorite word was for a plate with "CKP" - 10 points for 'Backpack.'

Not running, but there was a couple of year period that I was regularly walking in downtown Chicago over my lunch hour. Kept a map to make sure I covered every block of every street in the downtown area. Alleys too.

I maintain a computer museum in my bedroom. The second computer I ever owned, a 1996-vintage Power Mac 7100/80, proved unusually robust and although the original internal HD croaked eventually, machine itself kept on ticking. The third was my all-time favorite, first laptop, the 1998 "WallStreet", so at any time that a critical component died, I acquired a replacement from ebay and moved the RAM, accelerator, and hard drive(s) over and kept going. When the fourth and its twin were being retired in 2012, I realized that if I still had my first computer, I'd have all the computers I'd ever owned (orig or replica-replacements) so I went for it, acquired a Mac SE and the accelerator I used to have in it.

The cool thing is that they're all networked and I can Timbuktu to them all (even the ancient System 6 Mac SE, although it requires daisy-chaining TB2 connections).
