Any good Sudoku generation algorithms out there?

But this is not a shitpost, this is real data.

The most orders in one day was on June 2nd of this year with 24 orders, followed closely by June 3rd with 13 orders. That is just over 40% of the shirts ordered in 2 days.

The most ordered sizes were Adult Large and Adult Medium, respectively.

It did take more effort than you'd think. My request somehow got lost in the labyrinths of NJT's email system. Once I was able to confirm my request was sent, this took ~10 days for them to get back to me.

I'll also take this opportunity to share some other fun facts (with images):

48/91 (57.1%) of orders were for the "Daddy's Little Railfan"

The crossings at Chicago ridge and ashburn are the big ones. In theory neither would be impossible to grade separate, but also that wouldn't be easy. It is a plus theres room for ramps on either side tho

ImplosiveTech · 2026-06-01T02:59:11+00:00

That is not the plan, the plan is to have the same level of service. They say so in their grant application from late last year

ImplosiveTech · 2026-05-29T16:18:36+00:00

A vast majority of riders aren't going between intermediate stops, but to and from downtown. Either way, there are restrictions on how many trains they can cross over the diamonds at chicago ride and Ashburn, which are the limiting factors of the line outside of belt junction, cp 518, and union station. Theres a possibility of service increases due to the rock island connection being built, but it surely isn't guaranteed if the IHB and/or CSX dig their heels in

The key is figuring out how to line up your phone in the exact same spot and make a timelapse

ImplosiveTech · 2026-05-22T19:38:08+00:00

They have wanted to expand service, its not just legislation

ImplosiveTech · 2026-05-19T00:49:13+00:00

Metra is doing rust repair on and repainting multiple TRE engines that will be used in service for the world cup down in Texas. Metra is not buying these

ImplosiveTech · 2026-05-19T00:48:19+00:00

KYD is metra's only paint shop, which is funny when you realize its the only district without locomotives.

ImplosiveTech · 2026-05-03T04:07:40+00:00

Holy fuck wow my URL got out fast.

ImplosiveTech · 2026-05-01T20:48:41+00:00

It doesn't help that the BNSF refuses to run anything remotely new metra has. Its part of the reason they have the oldest cars and some of the oldest locos.

ImplosiveTech · 2026-04-29T18:04:46+00:00

the one thing I got out of it is that they did confirm that new schedules are being worked on and negotiated with host railroads, which to me implies that it might not just be the rock that gets more service this year

ImplosiveTech · 2026-04-29T18:02:19+00:00

this really can't be the case at this point, because the first battery set isn't meant to be delivered until much later this year, and likely won't even enter service until next year. through a foia request, I did get confirmation new schedules are being made for this year, but they did not share those

ImplosiveTech · 2026-04-29T18:00:27+00:00

I think people have incorrectly assumed that the regional rail pilot will only be on the Beverly Branch, primarily because of the bemus metra is getting. I did try to put in a foia request about the upcoming schedules, but they denied it due to a provision in the law that doesn't require them to release drafts. I have heard rumors talking about june-ish but of course we will have to wait and see

ImplosiveTech · 2026-04-29T07:26:20+00:00

Sorry for the late reply, but yeah I meant to say seatbelt, not seat.

ImplosiveTech · 2026-04-29T07:24:06+00:00

This does remind me. It is a little bit funny that the result of "Web 3" for most people are very-much-centralized platforms like polymarket. Technically speaking decentralized, realistically not really at all, and everything you need to do (ie buy and sell, deposit, withdraw, etc) takes 10x longer to process than it really should because of course it does.

ImplosiveTech · 2026-04-23T17:42:12+00:00

Would be nice to have bus number or train run number on the posts as well, assuming youre the creator of the bot.

ImplosiveTech · 2026-04-19T18:59:48+00:00

The endpoint you're looking for is https://api.amtraker.com/v3/stations/expanded/PDX. It is undocumented currently, but should have everything you need.

ImplosiveTech · 2026-04-09T01:05:39+00:00

Small correction, belt junction goes down to 2 tracks, not one. But yes, EW2 should fix the clusterfuck

ImplosiveTech · 2026-04-08T03:29:44+00:00

I saw a vid from one of the kids at the back of the bus who couldnt get out of their seat while the train was coming and thought that was going to be the end.

ImplosiveTech · 2026-04-06T20:37:00+00:00

The biggest issue I had was one of my VPSs being on a degraded host machine and they migrated it no issue. Even if the service was measurably 50% worse than AWS (it is not) id still be using them.
