“it is illegal for you not to like me”
This is the logical and inevitable conclusion of the last decade of elite media "free speech" discourse.

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
"Accountability without authority" would definitely be in it

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.

i think it's useful to look at areas where the *tech* has gotten much better while tech *interactions* have gotten way worse. streaming has gotten worse, google search has gotten worse, digital cameras are leaps better. apple's silicone is so good it's threatening their user upgrade cycle
it’s so weird to look around and realize like, tech and media are materially worse than a decade ago

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

Sometimes I feel we got a little bit too comfortable with blameless postmortems. We should introduce the accountability premortem. If something can fail and it was predictable, somebody should put their neck on the line, either to prevent it or to deal with the consequences if they arise

A related thing I’ve seen is decent software folks saying “at least what I do isn’t critical” as a way to distance themselves from the perceived responsibility/stress/burden of the things we work on, knowing the tradeoffs we make.
We’re given huge amounts of power and should act accordingly.

People forgot what happened to Enron and the Big 5.
It's not exactly the same kind of creative accouting, but there's the general feeling of "I'll build this big thing, benefit from it, it won't bring down my books and somebody else will hold the bag"

I really want to know the full story behind this epic hack, and yet I also hope it is never solved.
It's my favorite day! It's the 38th anniversary of the Max Headroom signal broadcast intrusion!
1st incident lasted 25s during the 9PM news on WGN-TV in Chicago; The 2nd, 2hrs later, lasted ~90s on PBS affiliate WTTW during Dr. Who.

Every day on here you learn another way the US is bonkers but especially today. Still, very probably a reasonable rule
Ok, so: I was raised in Boston and my first beat was in Rhode Island so I KNEW:
the rule you learned growing up as a kid, and then as a reporter, was this:
NEVER FUCK A KENNEDY.
NEVER GET INTO A MOVING CONVEYANCE WITH A KENNEDY.
NOT A BOAT.
NOT A PLANE.
NOT A CAR.

i somewhat rudely wrote a mini-thread about public speaking in the replies
i’ve gone from literally hyperventilating in a small room to confidently getting 800+ people to laugh while i tell them “you’re doing it wrong”
imo it’s worth a read

so the way i think about it is, it’s not about me. it’s about them. the audience is on your side, they want to enjoy your talk. they will forgive a lot if you are clearly working on giving them a good experience
making it all about you is the mistake (did i do x perfectly etc etc)

There is no difference in practice between removing rights of individuals and leaving the ECHR. The end outcome is still the same, people lose rights. If human rights are an obstacle to your policy it is not the rights which are the issue, it is your policy. Labour going full Reform at this stage.
