US governemnt: launches official government chatbot on america.gov Trump: will now have to call his own chatbot a liar because it says the truth
On america.gov, a screenshot of a chat:

Q: Was there any evidence that the election was stolen?

A: No official federal findings supported the claim that the 2020 presidential election was stolen.

• Election infrastructure officials said there was no evidence any voting system deleted, lost, or changed votes, or was compromised. CISA joint statement
• The Departments of Justice and Homeland Security said they found no evidence a foreign government manipulated election results. DOJ–DHS joint statement
• The Intelligence Community reported no indications that any foreign actor altered voter registration, ballot casting, vote tabulation, or reporting. Select Committee report, Appendix 4

Congress certified the Electoral College results on January 7, 2021. Isolated election crimes can occur; they are not the same as evidence that the national result was stolen.

Found it! Just past Rheine, a piece of farm equipment broke the overhead wire 😭

To fellow railway nerds: I am told there is an overhead wire break somewhere between Rheine and Amersfoort. However, neither DB or NS have it in their map of track issues, so I can’t tell where. Does anyone know where the break actually is? Is it in Germany or the Netherlands?

I agree, feels very much like a regional train. But at least the seats are comfortable compared to some of the other new sets on display

Luca Casonato 🏳️‍🌈 @lcas.dev · 25/09/2026
I had the same feeling when trying it, and so did @nicr.dev. The 1st class seats are like sitting on a wooden board with a faux-leather wrap

Very fun! I did find some of the hints not very useful, because they didn’t visualize why their assertion is true / how I could have come to that assertion.

I imagine the rest of the Dutch stops are done because this takes the regular slot of an NS IC between Enschede and Amsterdam, so if it didn’t stop it would mess up the clock face timetable every 2 hours? Idk if true, but I could imagine that this is the reason

@jensimmons.bsky.social, are you actually shipping this? It hasn't gone through standardization yet.

Uhm, why are they shipping BigInt math? That's stage 1, right?

I was kinda hoping your train would leave 9 minutes late, so that you can possibly complete the trip 100h or less 😀

bit of an update, it's been a few months now since I parted ways with Deno, and I'm starting to actively look for jobs again! I'm pretty good with big systems, compilers, and embedded. especially if rust or elixir are involved :)

I do not use my Google account as my password manager. I was independently giving two separate examples where I need passkeys.
020
Luca Casonato 🏳️‍🌈 @lcas.dev · 07/08/2026
This is the single biggest reason why I am unable to use Firefox everywhere. With Chrome I can bootstrap my password manager on a new device by scanning a QR code for a passkey. On Firefox I have to manually type a random 32 char string from my phone. That adds so much friction that I just don't.

Luca Casonato 🏳️‍🌈 @lcas.dev · 07/08/2026
Today we got our living room Steam Machine! I was going to use Firefox on it, but unfortunately I was unable to sign in to my Google account because Firefox still doesn't support cross-device authentication for passkeys on Linux. Had to download Chrome :( bugzilla.mozilla.org/show_bug.cgi...

Also I have a picture of the elevator - the maintenance sticker is from Italy wide operating elevator company that has 24/7 operation, maintenance, and emergency response call center as a key selling point on their website

Luca Casonato 🏳️‍🌈 @lcas.dev · 05/08/2026
You give them too much credit. These large organizations often do things “just because they’ve always done it like this”, even when there is no rational reason. Operating an elevator in a public place 24/7 is clearly not a problem, because all other countries can do it at their own train stations

i am talking about this internally right now, but i can make no promises for now you can use `railway up` from a tangled CI job tho - it should be pretty snappy, with the only downside you need to add a secret to the repo

that already works! i tried it today to deploy a tangled knot. you just have to put your username + app password into the "private registry credentials" section :)

+1 it's very good! Not just saying that cause I work there as well, have been using @railway.com for fun since 2021 and for serious work since 2023. my elevator pitch is that It's progressive disclosure for infrastructure

Here is a nice template if you want to spin up your own PDS for example: railway.com/deploy/xBNJ1u

So for those new to @railway.com: deploy basically anything in just a couple of seconds. Think a personal atproto PDS with persistent storage, a @tangled.org knot, or even a vibe coded (or meticulously hand written) site with postgres and a bucket. But really anything fits into a Docker container!

So some of you may know that I am a huge train nerd. So it's only fitting that today I start my new job at @railway.com. Not to run trains (I'm no good at that), but to help build the cloud platform of the future! Choo choo! 🎉 🚄 🎉 🚄 🎉
