Also just plain old fraud: selling Chinese models as Opus. With the capabilities of Chinese models catching up fast, this is getting more and more difficult to detect.

Even straight-out-of-the-camera JPG files have been heavily processed - they are just hidden behind the RAW processor which we have taken for granted; not to mention smartphone photographs, which employ neural network in the processing pipeline.

That is not what starnet does. It just removes the star from the picture you took, nothing else. It also predates generative AI by a few years.

If by "not real", you mean "you removed the stars so it no longer reflect reality!", then real photograph doesn't exist. For example, OP uses narrow-band filters, and it's common to map H-alpha wavelength, which is red, to green in the images. Does that make it unreal?

In the end, astrophotography is more art than science; the goal is more about producing aesthetically-pleasing images than doing photometry. Photographers must take some artistic license.

In the US it basically comes down to, is the delay the airline's fault? If no (eg weather, ATC), then nothing. However, most US travel credit card comes with trip delay insurance which would cover the cost of an overnight stay, regardless of the reason of the delay.

I do this religiously, and last time I got a fraud alert call for my Barclays-issued credit card, I called them back on the number on the card. They seemed amused and didn’t know what to do :(

Yeah I don't understand why all YouTubers seem to despise "the algorithm", and some of the creators I follow even created their own rival, Nebula, that does not have "the algorithm". Without "the algorithm" I wouldn't find out about your channel in the first place!

Further, in the US, non-iPhone have terrible resale value, so the monthly cost of iPhone can be cheaper

This is a significant problem for Chinese H1B holders, because the visa sticker for Chinese passport is only valid for one year. You can stay for longer, but cannot come back if you leave the U.S. Historically folks have been getting their visa renewed in Canada or Mexico, and this is already a huge annoyance - not only do you have to make a pointless trip, but also appointments in these countries are very hard to get as a Third Country National (TCN).

Sure, most other countries don't allow TCNs to apply for visa, but they also don't require their long term residents to leave the country to renew their visa.

So, the correct solution to this is Domestic Visa Renewal. A pilot program was run last year, but it was limited to Indian H1B holders. Without this program in place, disallowing TCNs is simply cruel.

Chargeback is not just for when your card is stolen. It’s also for e.g. when you never received your order, or your order is substantially different from what’s promised. It’s basically a last resort customer service option.

That is actually the idea. In this simulator, you design services that run on existing tracks. NYC subway is unique in the world in that there are a ton of interlining as well as quadruple tracks, so there are plenty of opportunity to improve system efficiency without building anything new.

I just tested it out. Since this uses OpenStreetMap data, it is very easy to adapt to other cities.

All input data and scripts are in src/data. Run the two Overpass queries, replacing New York with a city of your choice, and you will get JSON data on the infrastructure, as well as services. Replace the two existing JSON files, run the two transformation scripts, and you are done.

That is a good idea. I just added color for the tracks. I'm in the process of redesigning how trains look like.

As a Brooklynite I wholeheartedly agree. Unfortunately this is more of a service designer as opposed to a track designer, and it only works with existing infrastructure :(

Thanks - this is likely due to adding two tracks facing each other, i.e.

-->-->-- --<--<--

I'll add some logic to prevent such options from showing up.

Hello HN!

As a long term NYC resident, I have read countless articles on ideas tweaking subway services, but always found them hard to follow without visual aid. So over the long weekend I decided to build one. It has all the basic features: trains would spawn at their origin, stop at stations, and slow down if it gets too close to another. You can also design custom routes by piecing tracks together.

Have fun, and let me know what you think!

For home / away purposes it's easier to just detect if your phone is connected to the network. I built something like that before by shipping the log from my UniFi controller to a RPi and listen for events where my phone's MAC address connect or disconnnect.

Very cool! As a semi-frequent flyer I am also passionate about logging every flight I have taken. I have been using OpenFlights for the last five years but the constant bugs always bugged me :) This year I finally decided to build my own: https://jetsetter.quest

Yes, and it's especially frustrating for tailscale, since when it signs you out on the server you are often not in a position to re-auth
