Qatar Airways was voted the world’s best airline in 2025. Its booking site ranks 79th out of 111. Cathay Pacific, five stars, ranks dead last.

I spent a while digging into why airline websites are so slow, and what the fast ones (Ryanair, Frontier) do differently.

Slope chart comparing Skytrax 2025 service ranking with Calibre's website performance ranking for the ten highest-rated airlines. Lines connect each airline's service rank on the left to its performance rank out of 111 on the right. Nearly all lines plunge downward: Qatar Airways drops from 1st to 79th, Singapore Airlines 2nd to 31st, Cathay Pacific 3rd to 109th, Air France 8th to 95th, Japan Airlines 9th to 106th. Only Hainan Airlines rises, from 10th to 6th.

📝 Got to thinking about all the ways we use links:

- We save ‘em, we lose ‘em.
- We open ‘em, we close ‘em.
- We share ‘em, we hide ‘em.

Is your website using antiquated HTML?
vale.rocks Vale @vale.rocks · 7d
Sometimes you look at an old HTML document and see some weird tags and snippets from bygone eras.

I've complied many legacy HTML bits I've noticed and documented what they were and why there were present. Many of them are rather obscure.

Satisfy your curiosity: vale.rocks/posts/html-r...
Antiquated HTML Snippets and Artefacts
Overviews of the very many snippets of code that were once commonly included on websites to address specific cases with certain technologies, browsers, operating systems, or extensions. Fragments dating back to the days of Internet Explorer and Netscape, to more modern bits that are nonetheless obsolete.

What’s the problem w using LLMs to write stuff you want other people to read -emails, articles, posts- and why are people (like me!) so incredibly hostile that they will block you/mute you/block your domain, to never read anything from you again?

Take a break from being depressed that everything you love is being destroyed by slop for a moment and let me tell you about the beautiful symbiotic relationship between graffiti writers, train yard workers, and model train enthusiasts.

Flash was once the playground of the web: games, animations & experiments made by anyone with an idea. 💻 Preserving those creations helps recover a lost chapter of culture.

Jason Scott explores why Flash matters & why its preservation is vital.

Screenshot of a writing-analysis tool showing paragraphs of text with phrases highlighted in two shades of yellow, brown circular "3" badges, and a black tooltip overlaying the first line reading: "No X, no Y" chains · 3 "no" items. The visible text reads: We r[obscured by tooltip]nd up. No sign-ups, no downloads, no hassle (3) — just paste your text and start writing. Everything runs locally in your browser. The reviewer read the draft twice. Did not flinch, did not blink, did not reach for the red pen (3). That's the whole review, honestly. Don't call it a rewrite — call it a rescue. The improvement is real, and it's not subtle. That loss is worth naming. Sit with that for a moment. The gains were modest, but that's not nothing. You already know the answer, of course. Consistency is the entire game, and the punchline is that nobody wants to hear it. The entire pitch is one sentence long.

A New Color (1/5🧵)
Page 1: A man is walking home, smoking a cigarette, being quietly trailed by a UFO above him. As he enters his apartment, two aliens watch from inside the ship. Alien 1, who has a large head, says, “that’s him. Let’s move.” Page 2: The man walks upstairs as the aliens watch from the entrance of the building. The man enters his apartment and greets his little dog. Suddenly there is a knock at the door. Page 3: he peers through his peephole, and sees the two aliens standing in the hallway. Alien 1 is holding a briefcase. From behind him, the voice of alien one: “don’t scream.” Page 4: The aliens are seated across the room on the man’s couch. Sadie is in her bed next to them. Alien 1 says, “you’re not in any danger. Have a seat.” The man looks at his dog and thinks, “sadie is unusually calm.” Alien 1: don’t scream, or it’s a problem.
