Spec-Driven AI Development

You write a prompt, hit enter, and watch the console light up green. Code pours out. It feels like magic. Then you try to maintain the thing a week later, and you realize your shiny new AI agent just built a leaking bucket.

The identity \'iPhone Distribution\' doesn\'t match any identity in any profile

Today was the time for my yearly developer certificate renewal. After invalidating my old certificate and making a new one, removing all old profiles, I got the error above. It took me a little while to figure it out, but while I had generated my Ad Hoc distribution profile, I hadn't actually installed it, so I had my certificate set up for distribution but no mobile provision profile. Just my little d'oh moment, I hope it helps you figure out yours :-)

Finally iPad 2

When the iPad was announced, we got to hear we had to wait until the international launch date. So before it was even morning on the date of the international launch I ordered mine online, black 64Gb with 3G. I expected Apple to prioritize their own sales channel, but it turned out I had to wait 33 days from I ordered it until Apple expected me to have it!

Påskebryg by Ørbæk

Påskebryg by Ørbæk bryggeri was an instant hit. It has quite a strong taste, with a surprisingly lack of after-taste. It has a very nice foam, has lots of spice and hop, and is moderately sweet.

Willemoes Påske Ale

I'm a big fan of Willemoes which is Coop's brand by Bryggeriet Vestfyen, so when they had an offer too choose three for a reasonable price, I got two of Willemoes Påske Ale and a Påskebryg that will be reviewed another day.

Solution for "com.apple.transporter.util.StreamUtil.readBytes(Ljava/io/InputStream;)[B"

March 27th I had this problem that whenever I submitted an app to the app store with the App Loader or Xcode, that would pass verification mind you, I got an error: "com.apple.transporter.util.StreamUtil.readBytes(Ljava/io/InputStream;)[B" I wrote Apple to tell them about it, but I got an error due to a disk being full, so I figured nobody's perfect, it's probably a disk-full error, and tried the next day. The 28th, no luck either. Wrote them a mail. Didn't hear from them by the 31st, so wrote another mail. But by now, results had began to come up on my radar via Google, so I thought I'd share what I found.

Hornbæk Påskeøl

While many of the other easter ales actually could be great christmas beers as well, the Hornbeer Påskeøl is all flowers and "yellow" in taste, a very fine easter ale. It is a bit darker than a classic, cloudy with a nice white foam. The first taste is of spice and flowers, but not heavy at all. Very fitting for spring and easter.

Best all-time april fools day pranks

I've stopped doing april fools pranks, hoaxes and jokes, since unfortunately my jokes had a tendency to become true. "Dude, we've got a tax-misunderstanding" led to half a year of explaining why nothing was wrong. "DHL wants us to pay a strange import fee" wasn't fun when DHL called three days later. I talked to your boss and hear Microsoft has bought your company... a couple of days later... you get the picture.

The Danish easter ale story

I'm "imported" to Denmark, and guess what: so is the Danish easter ale tradition. As far as I've understood, the tradition started at the end of the 19th century when a few pubs in Copenhagen around easter would import double-bock beer called Salvator from the German order of Paulaner. This was a beer the monks had been allowed to sell since the 1780s. Whether it was actually the beer of the Paulaner monks is somewhat of a mystery, as this brand was so strong that all the Bavarian stouts were simply called Paulaner Salvator. Serving these beers turned out to be a huge success, so in 1905, Carlsberg, the big Danish beer brewery would make their own easter ale and sell it on tap. The year after, Tuborg, their arch rival, followed with their own easter ale on tap.

SQLite for the iOS SDK, two years later

It's been two years since I first wrote on using SQLite for iPhone SDK. Since then, iOS has come a long way, especially when it comes to storing data. But still, much remains the same. For instance, FMDB is still a great way of accessing SQLite databases directly, and if you're most familiar with SQL and don't want to learn too much new stuff (learning Objective-C and Cocoa can be enough by itself), this is a great way to write your first apps.
