There are at least dozens of us doing this. My $5k bloated corporate laptop sits in my office 24/7. The 25% of time I’m traveling is with a $300 Chromebook with Linux Mini, a Bluet…

I think the root of much of this are money laundering rules. The feds want to be able to punish bad guys without actually proving the crime they are suspected of. There are now a l…

Everything about this looks fake, and Tesla confirmed it wasn’t real. Not finding great sources right now: https://www.carscoops.com/2025/08/rapper-fakes-video-claimin... I would b…

In order to consistently output the same fake prompt, that fake prompt would need to be part of GPT’s prompt…. In which case it wouldn’t be fake. You can envision some version of p…

It is doable but highly location based and still really tight. I’m in a tier 2 US city. Our interns wage would equate to $58k annually. A car isn’t needed if in the city. Most peop…

State governments do this too. NY under Cuomo just dictated a 10% cut to invoiced labor. It was widely understood that saying no meant no more work in the future.

Potentially this is like giving an axe murderer an uzi. They don’t need it, but they’ll probably be more effective.

Alon Levy being brought up on this topic always tweaks my “but somebody is wrong in the internet.” I’ve been on several of the projects he talks about. He’s right about the macro n…

I really like this idea; I’ve made crappy versions myself a few times…. Maybe this one will stick. (For others, it’s a method to follow people across multiple services without bein…

Is AmEx any better? I’m planning to cancel my Mastercard with this gatekeeping as a reference to why. It seems to be the most effective lever most of us have.

It’s done in various places. NJ Riverline is an example. There are a bunch of others. The bigger problem is the freights just have no interest in sharing the tracks with passenger …

As a mid size company that does work with government agencies, it’s near impossible to use anything ‘better’ solution. Cybersecurity requirements are getting so onerous that Sharep…

Having H1-B visa employees introduce overhead. Not all companies are willing to do it. We’ve recently decided to stop H1-Bs for anyone that isn’t a senior hire.

I wish they’d named FSD as Autopilot. FSD is amazing and I use it door to door wherever I drive. I got a LOT better about a year ago. But it still makes some dumb mistakes. It is n…

I believe this is only used on one passenger line in the entire country. This is really a freight based system intended to transmit brake apply signals as speed of light instead of…

Yeah. Exactly. The consequence of this club is either: 1) The brakes take an extra couple seconds to apply (note: this is only used on long trains… so stopping is over a minute any…

It’s really frustrating seeing all this about something I know about. ‘Slamming in the brakes’ is the default safe condition for a train. The freight train Positive Train Control d…

This isn’t how US trains work though. There is literally an air pipe from end to end. It leaking air is how the brakes are normally applied. The system with the vuln is just an ove…

I work on trains. This is FUD. Except for 1 train in the US, no passenger trains use this function. It is only for long freight trains. If you block it, the train still brakes…. Ju…

I've actually used this fact in a related way, for wayfinding. Old school Open-CV was able to see tracks well from an onboard monocular camera, but calibration and scale was annoyi…

Substack simply has better quality. I've been involved in some things a handful of times that made it into the paper. Technical laws being passed, corruption, complains about a sys…

A coworker of mine was punched on NYCT. Went to the cop in the station, who did nothing, and was sore for a week. This is a case where it was ‘reported’, but the cop said they coul…

I was going to say “I’d be surprised if organ support is a large issue to an adult. We already have long term astronauts and people who are bed ridden for a long time during recove…

Exactly this. Facebook makes money by network effects. They are incentivized to grow network engagement, more than they are to make direct money off new network members.

Is the air gap actually an issue in this case? If I'm understanding correctly, the suggestion is to put up additional cable instead of thicker cable. The two ends of the cable are …
