It's amazing that posting this on HN has not melted it down. Are you using an edge CDN like Cloudflare to provide caching?

Perhaps I'm not being very generous, but I'm often kinda surprised when sites do meltdown from the HN effect -- although I recognise it depends on a lot of factors.

Wow, that's probably about the same ram & cpu as my desktop 16 years ago.

I started with a Pentium I, 166Mhz, 16MB, 1GB HDD, and I'm not even that old. I imagine we have folks here that started on a PDP :-) My P1 would stutter while playing MP3s :-))

I really appreciate that CPU manufacturers started adding dedicated hardware for things like decoding MP3's. Not sure about the machine learning hardware they put in it nowadays, but then, that's mainly Apple who do a lot of that for e.g. your pictures (so they don't have to send it to their servers).

if it's pure static you can easily server thousands and thousands of request per second no problem.

This website returns 40.5 kB from nns.ee host (with CSS and SVG). 1000 users per second requires 40.5 MB/s or 324 Mb/s connection. Author mentioned that his device provides 10 Mb/s throughput. So realistic number is serving 30 users per second.

For some reason his main.css is not compressed, so that would be the first thing to optimize.

The Quectel modems are fun parts. We are using one in a project as a kind of theft protection. I couldn't belive at first "this is a whole computer with Linux on it". I really wonder why modem manufacturers feel the need to encapsulate everything so much. Is it for regulatory reasons, to protect their secret sauce, or for our convenience? On the one hand it makes simple things really easy with some AT commands, on th…

Regulatory reasons. There are a lot of things that FCC regs say that devices that transmit either must or must not do, which made more sense back when everything was analog. Now that the device is a full computer and can be programmed to do whatever you want, the way the industry has decided to best fulfill all those requirements is to make the computer do exactly and only what is required and then lock it down into…

Do those regulations explicitly say that the RF device is not allowed to be programmable by the user? And isn't the user legally forbidden from substantially modifying the RF behaviour in any case?

Seems like it’s currently melted right now.

Edit: ah, not. Looks like it’s reachable from my landline (which is IPv4 only) but not from my 4G connection (which has IPv6).

Any chances that opening a root shell into the modem can be used to grab the closed firmware, reverse engineer it, then swap with an open source one? I mean it's not just about security but also being able to implement nice things to have running and connected while for example the phone operating system sleeps between calls.

When I was a kid we had a BBC Micro. In university we had CD burners but if you bumped the computer or did anything else while it was burning the CD, the disc was ruined. :P
