I don’t know if this is an iOS 27 thing or it’s always been like this: when you’re on a wifi network that doesn’t support IPv6, IPv6-only destinations route over mobile data (
if it supports IPv6 and you have Connectivity Assist turned on, which is the default.

Maybe IPv6-only destinations are rare enough that this isn’t a big problem, but it’s kind of shitty to split routing like this. #ipv6

Happy 30th birthday to the one, the only, Windows NT Workstation 4.0!

I still remember when my dad brought home our first Pentium PC and it was running NT 4.0. Rock-solid OS that did everything you needed.

And here we are 30 years later and I still install this OS for fun and the startup sound still brings me the warm and fuzzies.

I may or may not have just bought a pocket PC so I could add another user agent to my collection.

And fun surprise: it supports IPv6 out of the box! Windows Mobile 2003 SE had its act together.

Every now and then you come across a piece of software you just can't find anywhere on the internet. This time it's the Ericsson WapIDE.
The tool was free, but it required registration to download, so archive.org doesn't have any copies of it.
I'm almost tempted to just go to the Ericsson offices in Lund tomorrow and ask at the front desk.

Unfortunately, IE6 with IPv6 doesn't work on Windows 2000. Firefox is aware of the IPv6 implementation for Windows 2000 while IE6 is not. Funny, that. https://bugzilla.mozilla.org/show_bug.cgi?id=252195

I spent more time than I care to admit doing dual-stack IP detection in a way that works on modern browsers and all the way back to Internet Explorer 6.

I learned that IE6 will refuse to do XHR unless the host+port are identical to the current URL, and it doesn't support CORS. So, the workaround was using JSONP.

I wonder how many other people in the world have IE6 running with IPv6 support...

Of course it's not the right tool for every job. For large payloads of tabular data, the verbosity adds a lot of overhead with serialisation, transmission, and parsing and then you're better off with something like Message Pack or Protocol Buffers.

YAML is great for lots of cases. Compact syntax, built-in support for heredocs, no unnecessary quoting, value references, clear structure. Stuff like "the Norway problem" is kind of a facepalm but avoidable.

Having dealt with XML for 20+ years at this point, my opinion on it has largely evolved into: it's the worst markup language aside from all the others.

In all seriousness, when done right, XML is actually quite nice.

I think early frustration with XML came from developer decisions like improper/overuse of attributes, lack of XSD, and questionable structure decisions like repeating elements without containers.

New law: any UI that has a “remind me later” or “not now” button must also have a button for “I never want to see this again, ever”
