Anthropic's new Claude Fable 5.2 prompting guide has an interesting little trick. Tell the agent it owns the codebase and it's much more likely to consolidate duplicated code. In their testing it went from under 10% to about 50%. Unfortunately it also started making changes nobody asked for. Not sure I'd be trying that one on a client's website:)

Windows XP Home Edition, Service Pack 2 already on the disc, "for distribution with a new PC only." The holographic Bliss hillside still looks like 2002 even when the rest of the label has gone rainbow. I loooved XP:)

In PHP 7, 0 == "abc" was true. Compare a number with a string that isn't numeric and PHP turned the string into a number first, so "abc" became 0. PHP 8 compares them as strings instead, so it's false. Old code that leaned on that quirk didn't throw an error after the upgrade. It just started giving different answers. === would have saved everyone the bother.

Yep. There’s a few of those, but any real developer wouldn’t compare a number and a string without knowing the outcome. isEmpty vs isNumeric are also worthy of understanding.

The problem isn't writing code like that yourself, it's inheriting 15 or 20 year old code that somebody else wrote. plenty of those little quirks buried in old PHP projects, and they don't always make themselves obvious when you upgrade🤷‍♂️

Long uptime used to be bragging rights, screenshots and all. On a Linux server, it can also mean a stack of kernel fixes were installed but never loaded because nobody rebooted. `uname -r` tells you what you're actually running.

yeah it was so strange and my account had sat stagnant for about 3 weeks prior to that too, almost as if X felt sorry for me and gave me a push lol

Norton AntiVirus 2003, with a stethoscope on the label and a note that the CD can be used as an emergency boot disk. Rescue media used to be a physical thing you hoped you wouldn't need, and hoped you'd kept.

Norton 2003 definitely had a concept of viruses. It also had a remarkable ability to make a perfectly healthy PC feel terminally ill 🤣

Good Morning Tech Twitter! 🌤️ The big 6K is getting very close. So it's time to go REALLY niche.😬 I want to connect if, like me... You're a Windows PC user. Because the only time a Mac saved Earth was in Independence Day... And that was fkn fiction. You think Claude sounds like a French waiter... But CODEX sounds like the bloke who comes round to break his legs. And you think the 'Apple ecosystem' is just Stockholm Syndrome with Bluetooth. If that's you, CONNECT WITH ME!🤝 There must be at least six of us... Seven if Jerry Seinfeld hasn't gone soft. 👊 You're in right! Right??? 😂

It feels very all over the place for me. Sometimes it's barely nothing, then a lot, then medium for a few days...then nothing. It's kindda weird.

So I just posted my EZHAMShack project over on Reddit. They nuked it in 15 minutes because it was "vibe coded". Not on the merits of what I actually did or how it worked. There wasn't enough time. As bad as X might be at times, it's not as bad as that shitshow! FUCK REDDIT!

It's bloody ridiculous. A bloke spends his time building something useful, shares it with the community, and gets kicked in the teeth because they don't like how he wrote the code. Whatever happened to judging software by whether it actually works?

Scott Hanselman has wrapped Windows Sandbox so an agent gets a brand-new Windows 11 machine, installs your app, clicks through it, keeps the screenshots and crash logs, and then the whole machine is thrown away. Plenty of agent setups still run on the same laptop that has your SSH keys and browser logins on it. Where does yours get to install things?

Docker is also a lighter weight alternative or Rancher Desktop if you want oss.. i bet this Windows Sandbox thing is way to do the same without having to get windows os images

Yeah, Docker's great for plenty of things, but it's not quite the same job. The interesting bit here is giving an agent a proper clean Windows desktop to install software, interact with the GUI and test native apps. Windows Sandbox doesn't need a separate OS image either, which is pretty handy.

Did you have like one post or reply that is now 99% of all your impressions ever?

No, i've had a few blow up, one got 700k impressions or something but they only ever generated 50 follows or something. The algo is weird🤣
