When the Magsafe connector is plugged into a Mac, a lot more happens than you might expect. I believe the following steps take place:
The charger provides a very low current (about 100 µA) 6 volt signal on the power pins (3 volts for Magsafe 2).
When the Magsafe connector is plugged into the Mac, the Mac applies a resistive load (e.g. 39.41KΩ), pulling the power input low to about 1.7 volts.
The charger detects the power input has been pulled low, but not too low. (A short or a significant load will not enable the charger.) After exactly one second, the charger switches to full voltage (14.85 to 20 volts depending on model and wattage). There’s a 16-bit microprocessor inside the charger to control this and other charger functions.
The Mac detects the full voltage on the power input and reads the charger ID using the 1-Wire protocol.
If the Mac is happy with the charger ID, it switches the power input to the internal power conversion circuit and starts using the input power. The Mac switches on the appropriate LED on the connector using the 1-Wire protocol.
Reconnects to your VPN automatically. Crazy that you need an app for that, but it’s just $1.
Impatient to get a new iOS, I’m customizing OS X instead. App’s a bit over-designed but it feels reliable.
Damnit. Desktop Groups is exactly the app I want — displaying arbitrary folders’ contents on the desktop — but without the necessary polish.
Je crois que j’ai trouvé mon erreur, c’était de ne pas assumer l’inspiration Windows Phone à fond en mettant tout dans des carrés.
iBooks Author is a fine little toy. I could easily lose many days making stuff I don’t really need, like a photography portfolio on iPad.
So there’s only a $100 difference between the 5C and 5S, which is both disappointing and not all that surprising.
RT @pgor: Reminder: iTunes charges more for one song recorded 30+ yrs ago than some feel an app taking months for a team to develop today should cost.

FINALLY as a dev I can gleefully abandon old iOS versions in my updates.
RT @stroughtonsmith: App Store versioning solves a major issue for old devices: booting iPhone 3G right now shows you a store full of apps you can’t install.
RT @danielpunkass: I’m waiting for an iPhone 5S review that includes setting a fingerprint lock and then passing it around a room of 300 people.
RT @danielpunkass: If I seem grumpy, it’s only because I hold everybody to the same standard of excellence that I fail to meet.
RT @stroughtonsmith: iOS 7 fits less characters in an app name on SpringBoard, so you might be forced to rename your app/brand to fit. Dumb change.
RT @danielpunkass: To put Apple’s iPhone 5 sales in perspective: 1 out of every 800 people on the planet ordered one over the weekend.
You know, the ones that aren’t superellipses.
Premier essai de Paris Wifi — WTF, ça marche super bien, il doit y avoir un bug quelque part. (Bon, connexion VPN refusée, mais j’accorde.)
