Comment Re: "far too small to generate any lift"?? (Score 4, Interesting) 106

That's how I read it. It should say it has no thrust.

A typical jet turbofan airframe has two engines that each have a generator shaft taking turbine energy and making electrical current. It then has a whole 'nother turbine engine used on the ground and in some other flight legs called the APU; this exhausts out the tail cone usually, and can start engines or provide extra hydraulic power if needed, but is slow to start just like the main engines.

For power loss emergencies, a small spring-loaded fan pops into action super fast, called a Ram Air Turbine or RAT. It can only make enough electrical power to reboot key systems like engine FADECs or avionics, often only on one electrical channel instead of all channels. It's only a turbine, not a thrust-producing fan. It's a pinwheel toy in comparison to the APU and even the APU cannot produce significant thrust.

Comment Re:News flash, subtext (Score 2) 34

AI scrapers use these residential proxies. It's not (just) VPNs and Tor routing. Several bottom-feeding companies openly advertise such scraping services, for pretty much any country you may want. I administer a wiki that's been on the receiving end of such scraping, and the majority of these scraping requests are in fact coming from residential IP-addresses rather than data centers.

I don't know whether these are hacked accounts, people getting tricked or paid to run these scraping apps on their devices, but it's impossible to block them all. Even if you let fail2ban block entire /24s for every detected hit (even disregarding the collateral damage and the fact that these blocks don't solve the issue, the fail2ban and iptables overhead starts to outweigh the apache load at some point).

Anubis seems to be taking care of it for now, but it's obviously only a matter of time before they can deal with that one too. Although its delay does enable fail2ban rules to block the IP-addresses before they get to stress the mediawiki php scripts, attempting to diff 2 revisions of a random page from 10 years ago.

Comment Re: The AI voices are awful (Score 1) 51

For the Irish language course the recordings of native speakers were taken offline in 2023. The AI replacements are nonsensical.

This story is about AI generated courses, not voices, but my post was still (accidentally) on-topic: when they previously used AI to increase volume of content, they were ok with quality being thrown out the window.

The AI generated courses might be low quality, and the original (English) courses might also go downhill because the type of exercises they produce may now be restricted to the type of things that their AI is able to reorganise for other languages. E.g. it might go further in the direction of vocabulary memorisation.

MAILBOX NAMES FOR COMMON SERVICES, ROLES AND FUNCTIONS

"If a host is not configured to accept mail directly, but it implements a service for which this specification defines a mailbox name, that host must have an MX RR set (see [RFC974]) and the mail exchangers specified by this RR set must recognize the referenced host's domain name as 'local' for the purpose of accepting mail bound for the defined mailbox name."

Oops.

No MX record.

That means a mail exchanger would use the A record for the mail server.

That implies that there is a service running on port 25. Well, is there?

Nope. Not RFC complaint.
