So the plan was to do a re-run of Venezuela.

Keep the dictatorship, but with a more «US-friendly» leadership.

Fun fact : Par sa décision, le @conseil-etat.fr n'a pas seulement validé la liberté d'utiliser l'écriture inclusive.

Il a aussi entériné ce que les juges administratifs ont retenu :

Le fait que l'Académie française « se soit déclarée opposée à son usage » n'a... *aucune* incidence légale.

Counterpoint: we have lowered our standards so much over the years that AI became usable for it.
And now AI is helping us reach new lows we could not imagine before

One thing I love about the Onion staff is that when you click on these articles, it's clear they do actually read our media releases.

Excerpt from "now it can be told":
"
The piles themselves were surrounded by heavy shields of steel,
pressed wood and concrete, to protect the operators from the extreme
radioactivity that accompanies the formation of plutonium. The energy
of this radiation is cquivalent to that of hundreds of tons of radium,
Each pile was located within an area of one square mile. At first
they were six miles apart. S additional piles became necessary,
we planned to intersperse them between those already in existence, so
that the distance betwee them would then be three miles.

Design of the equipment for the chemical separation plants had to
i
keep abreast of, and in some cases ahead of, the development of the
process itself. Fortunately, the two separation processes that seemed
to offer the best prospects employed virtually the same equipment and
piping layouts, SO that it was possible to go ahead with a design the
first stages of which would be suitable for either process. Almost every
one of the major design decisions for Hanford had to be made before
the Clinton pile was in operation.

Oricinally eight separation plants were considered necessary, then
Six, then four. Finally, with the benefit Of the `perating experience
and information obtained from the Clinton semi-works, we decided
to build only three, of which two would operate and one would
serve as a reserve. I should like to point out that these separation
plants were designed when we only had sub-microscopic quantities
of plutonium. Here again, each plant was provided with its own water
system and steam plant and the other service facilities needed for
independent operation. Each plant was a continuous concrete struc-
ture about eisht hundred feet long, in which there were individual
cells containing the various parts involved n the process equipment.
To provide protection from the intense radioactivity, the cells were
surrounded by concrete walls seven feet thick and were covered by
six feet of concrete.

The European Union has triggered Article 122 to indefinitely immobilise the assets of the Russian Central Bank, worth a whopping €210 billion.

I explain what just happened and why this is such a big deal for Europeans.

Maybe we should introduce "seniority without accountability", that would fit very well with modern software development practice

Oh, that's interesting. It's probably a useful measure of value against the rest at the instant, but is it stable enough over time to use it again as money?

Considering gold is mainly used as an investment vehicle, without any large practical use in industry, that sounds like a weird metric

You'd think that by this time they would have built a proper business and not need anymore to push snake oil, but no, the grift continues

I have been saying for quite a while now that, any time somebody tells you that their thing is "end-to-end encrypted" you must smile and nod and go, "oh that's cool, very nice" before fixing them with a steel glare and asking, "between which two ends?"

As someone who works on the interaction layer of software: it's this.

Stupid trends in hardware self correct after a generation or two, but *software* ratchets in the direction of unusable because designers are occupied with interaction patterns and not whether the fucking thing works properly.

In this forsaken period of performance reviews, remember the one joy you can get out of it: endorsing your friends for the things they are good at but will never admit, potentially putting them on the career path they would not dare to try

BREAKING: This is huge news, the EU's equivalent of the 🇺🇸Supreme Court's 2015 Obergefell v. Hodges ruling.

🇪🇺Court of Justice just ruled all 🇪🇺countries must recognise same-sex marriages granted in other member states.

This effectively legalises gay marriage across 🇪🇺
