As an experiment, we (the Firefox team) wanted to try a new way to get feedback on which Interop proposals matter most.
So, here's a web app where you can rank the proposals you care about, giving us data we can use when reviewing which ones to champion.

The new MDN frontend (we call it Fred) is live after about 5 months of work, and a lot of planning and prototyping before that!
Rebuilt using web components, it should feel a lot cleaner and more consistent for users, and is so much easier to develop in.

Anyone who thinks you can solve London's housing crisis, the product of several decades of not building enough houses, without building more houses, does not deserve to be taken seriously. Nor does anyone tagging the NIMBY ultras of CPRE into a discussion on housing.

Whether it's Obama wearing a tan suit or Donald Trump tanking the economy, alienating America's allies, sending innocent people to torture camps, destroying the free press, and causing millions of deaths worldwide by ending USAID, both sides have brought great shame to our country.

If I'm reading the charts right (very possible I'm not), looks like the power outages in Spain & Portugal are somewhere on the demand side, rather than supply side (i.e. a power plant didn't fail, something transmitting energy did). Here's the forecast vs actual load for Spain today:

I can't stop laughing at this man I'm sorry. This is the kind of shit the biggest loser in the world would say to their girlfriend about buying her flowers on Valentine's Day once, and he's doing so in an argument that started because he called her a bitch

Vance is a fucking snake. Trying to pretend other people have to show decorum as he’s out there calling Zellensky a loser. Fuck that guy.
How can America look at how they ganged up on Zellensky like a pair of bellowing kids & feel good about this

“As Trump asked him who was ‘holding the cards’ at the moment, the Ukrainian leader – whose countrymen and women were fighting and dying against Russian aggressors even as the meeting took place – was desperately trying to make the point that none of this is a game to him.”
Trump's bullying of Zelensky reminds the world that business as usual is over
The world’s greatest superpower just humiliated a wartime ally in public

Of all the teams the Lions could lose to, I'm glad it was the other team in the league which plays like they're playing real life Madden. Gonna be rooting for them the rest of the playoffs!

Nwaneri's confidence is absurd: 4 players inside who he could reasonably pass to, but he runs at goal and smashes it in the back of the net - that kind of attacking spirit and speed is something we've been desperately lacking. Is he just too young to feel pressure? #Arsenal
