Submission + - "Miss" causes serious incident on plane after passenger weight mis-calculated (theguardian.com) 1

AmiMoJo writes: A software mistake caused a Tui flight to take off heavier than expected as female passengers using the title “Miss” were classified as children, an investigation has found. The departure from Birmingham airport to Majorca with 187 passengers on board was described as a “serious incident” by the Air Accidents Investigation Branch (AAIB).

An update to the airline’s reservation system while its planes were grounded due to the coronavirus pandemic led to 38 passengers on the flight being allocated a child’s “standard weight” of 35kg as opposed to the adult figure of 69kg. This caused the load sheet – produced for the captain to calculate what inputs are needed for take-off – to state that the Boeing 737 was more than 1,200kg lighter than it actually was. Investigators described the glitch as “a simple flaw” in an IT system. It was programmed in an unnamed foreign country where the title “Miss” is used for a child and “Ms” for an adult female.

There is a huge difference between this and science: Scientific results can be highly complex and hard to understand, but the standard practice is that they are reviewed by multiple people before being accepted as true.

The reason for this is obvious: scientists know very well that complex things are likely to be wrong at the first attempt :)

So a huge piece of software, which was not reviewed by anybody besides its authors, should never be trusted.

Not necessarily. Suppose that the database lookup gives erroneous results with probability (let's say) 10^-6 (for whatever reasons). Then if you are entering 1000 cars manually, you will have on average less than 1 false positive per year. If you harvest 10M license plates per day, you will be getting an average of 10 false positives *daily*. People are not going to be pleased by false accusations...

Not at all. Robot is derived from "robota", which is an old Czech word meaning just "work" (derived from "robit" meaning "to work"). In the middle ages, its meaning shifted to mean "mandatory work for the feudal lord", regardless of whether the subject was a free man or a serf (there were no slaves in Czech kingdom at that time). Contemporary meaning is just "any hard work".

In 2007, Wikipedia's english site had 1.5 million articles; in 2015 it had 4.6 million. That's three times as many individual articles, with every edit to every article stored forever. The number of pieces and sheer amount of data stored and indexed is a complex, temporal function. For the number of articles, it's (time x rate[article creation]); for the number of pieces of data created, it's (time x rate[edits per article] x articles). Because the number of articles is increasing over time, you're looking at an exponential growth function. Note that it's exponential and not geometric because the rate of edits is related to a polynomial exponent of t, since the number of edits per time increases with time thus (t*(t*r)).

Wrong. Even if I don't dispute your assumptions (constant rate of new article creations, constant rate of edits per article), the resulting function is quadratic, not exponential.

Also, the majority of historic versions is probably seldom viewed, so they do not contribute to site load much.

Unfortunately, DMARC breaks even mailing-lists which do not tamper with the contents of the messages at all. The reason is simple: SPF. Rewriting envelope senders is the proper way of forwarding mail since ages.

If you want to have proper integrity checks of e-mail messages, use PGP, not DMARC.

What they mention is not a list of solutions, but a list of silly work-arounds, which break well-established semantics of e-mail headers. Falsifying information about the author of the message (that is, the From header) for the sole sake of making the message compatible with DKIM is broken.
