Leo McArdle 🇺🇦

£5.62 returned for each £1 spent on cycling investments, finds @cyclinguk.bsky.social study www.cyclingelectric.com/news/5-62-re...

The "zionism is racism" motion that has just passed on the Green Party's conference floor is truly gross, and deeply racist. The party's MPs deserve some credit for opposing it, though they should've done so more stridently and sooner. This is now a millstone around the party's necks. Deservedly.

I see a lot of people complaining about the undoubtedly stressful conditions at present on London's roads. But I see few people complaining about motor vehicles. Yet in the last 24 hours three vulnerable road users have died after being hit by people driving motor vehicles.

She is so brave and good. I hope she doesn't get too much grief.

We must take on the hateful forces that seek to divide us. My statement on recent events in Belfast.

Elon Musk is paying fascists to riot and attack minorities in our cities. Some he is paying, others he doesn't need to, the X algorithm and revenue program do the rest. The UK's leading nazi thug is posting from a Moscow hotel room right now. We need to wake up to foreign money and the far right.

The correlation between social media usage and political instability is so strong as to demand serious investigation. But it isn't happening. Are humans actually the frogs being slowly boiled to death?

X and Elon Musk has been a threat to public order for nearly two years. The government has taken no action.

Absolutely agree. The problem with X doesn’t stop at nudification tools, child porn and AI slop, it’s the deliberate destruction of democracy and security in our country.

We need to think deeper: why is this unacceptable for a 17 year old but acceptable for an 18 year old - or a 57 year old? Age controls are not the real problem.

From Gamergate, to Blake Lively, to Brexit, to ‘two tier policing’, we know, we have data that most of these campaigns aren’t ’real.’ They’re primarily the work of bot farms employed by hostile nations. So why is this never discussed on a mainstream level?

Saying the officers initially believed the killer because of anti-racism just doesn't make sense. Run through the sequence of events as I described them. If you honestly think the police would've done anything different if the killer were white, please explain how, because I just don't see it

The right in this country have totally lost it, a complete and utter collapse of any kind of cordon sanitaire with the far right in favour of gutter racism. It's been slow, but the grinding move from "anti-white racism is real" from far right agitprop to Times leader is complete.

Appreciating it's a buzzword currently but this is just elite radicalisation. There is no significant constituency in the UK for this sort of open racial animus, and yet it has totally permeated the right's "intellectual" spaces.

Even though I've moved away, I'm rather sad Westminster council goes back to the Tories. Labour were doing good things for cycling in the borough, and who can forget or forgive the £9m the Tories wasted on the Marble Arch Mound: www.bbc.co.uk/news/uk-engl...

This React -> Web Components post by the MDN team touches on challenges and solutions I've seen dozens of times over frontend's lost decade. Kudos to them for the improvements in performance, and the bravery to tell the story in an unvarnished way: developer.mozilla.org/en-US/blog/m...

Cool to see #MDN exploring a unique #frontend architecture which better meets their needs. developer.mozilla.org/en-US/blog/m... #web #JavaScript

Under the hood of MDN’s new frontend. @leo.mca.is explains how MDN replaced React with web components and Lit, using server components for static content and lazy-loading interactive islands. #mdn #webcomponents developer.mozilla.or...

Really great write-up, and spoiler alert! ... MDN uses Lit to write their web components! 🔥😎 And they use Lit SSR to implement their own server components, and built their own component lazy-loader. Impressive work MDN!

Under the hood of MDN's new frontend 🛠️ We rebuilt MDN from the ground up. ⋅ Web components for islands of interactivity ⋅ Only the CSS & JS each page needs gets shipped ⋅ Dev server starts in 2 seconds (down from 2 minutes) Read the full story 👇 developer.mozilla.org/en-US/blog/...

A reminder to the news media: “conflicting accounts” is what you say BEFORE the incontrovertible video evidence appears. After that, your job is to ask why one side is lying, not to repeat the lie and pretend no one knows the truth.

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. interop-rank.jakearchibald.com

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:

LIGHTNING STRIKES RICE

The problem with Dems chasing public opinion is that THE PUBLIC'S VIEW OF THINGS IS JUST MOVING IN RESPONSE TO WHAT POLITICAL FIGURES SAY AND IT'S VERY OBVIOUS IN THE DATA MY GOD

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

(on a personal note it's quite striking how quickly I've gone from "generally a bit of a pinko on defence issues" to "and could I just do a monthly direct debit to BAE Systems, would that help")

Zelenskyy is my hero. A true anti-fascist. A man with more bravery and dignity in his other finger then most of his detractors will encounter in their lifetime

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.”

JD Vance is a snivelling little shit, but thanks to him I'm now donating £100/month to Ukraine: u24.gov.ua

Your dignity honors the bravery of the Ukrainian people. Be strong, be brave, be fearless. You are never alone, dear President Zelenskyy. We will continue working with you for a just and lasting peace.

The most shameful day for the United States of America in any of our lifetimes.

Today's drawing

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!
