> What happens if a train has to stop in the middle of the tunnel, and you phone for help? [...] the system has been deliberately configured to transmit the location of the nearest tube station, where access can be arranged. That’s why sometimes you might check your smartphone map, and it will display the “wrong” location, because that’s the best one for a 999 call to use.

This doesn't seem correct - cell towers don't just transmit a location that phones then pickup and use? Unless this is some emergency specific feature I'm not aware of?

A perfect example of the state of IT in Australia.

Doesnt CGNAT make these methods obselete though? All my webscraping is proxied through my phone and I rarely get IP blocked and im very aggressive even on CF protected sites.

That's neat, could you explain how you achieved that?

I tried a year or so ago and had to round trip to my Android over mobile data so it was too high latency for what I needed. If there's a way to connect to a phone on the same LAN/WiFi but scrape using its mobile network I would be very interested.

Mentioning this as an example use case is simply untrue, right?

Hear hear. Poor article going out the door for publication with zero editorial checking.

Haha yeah just noticed they call Bytespider "TokTok's crawler" too

> “OpenAI used 600 IPs to scrape data, and we are still analyzing logs from last week, perhaps it’s way more,” he said of the IP addresses the bot used to attempt to consume his site.

The IP addresses in the screenshot are all owned by Cloudflare, meaning that their server logs are only recording the IPs of Cloudflare's reverse proxy, not the real client IPs.

Also, the logs don't show any timestamps and there doesn't seem to be any mention of the request rate in the whole article.

I'm not trying to defend OpenAI but as someone who scrapes data I think it's unfair to throw around terms "like DDOS attack" without providing basic request rate metrics. This seems to be purely based on the use of multiple IPs, which was actually caused by their own server configuration and has nothing to do with OpenAI.

You can take this a step further and get one of those 5-in-one/7-in-one weather stations and then listen to its communications to its basestation with an RTL-SDR using rlt_433 and then pipe those datapoints into a Prometheus + Grafana installation.

If you're lucky a neighbour may already have a compatible weather station nearby, which you can freely collect data from as long as you're in range ;)
