Repair Permissions is Useless

Repair Permissions won't touch any files in any of the user's home folders since Installer.app can't target user folders specifically, only any folder or a specific path, and there are no packages in ~/Library/Receipts/. The only way it'd ever touch any files in a user's folder is if you installed something that let you explicity select a folder to install in (there are very few of those, none are available from Apple publically) and you chose a folder inside your user's folder. The receipt would still be installed in /Library/Receipts/ and it would only affect the user that installed it. It also won't fix permissions for any files that were created during the normal (or abnormal) use of OS X. This means it won't touch any cache files, database files, swap files, or settings files not created by the installer. If a file isn't listed in a receipt, it doesn't exist to the repair permissions process. It's really as simple as that.

πfs (pi filesystem)

One of the properties that π is conjectured to have is that it is normal, which is to say that its digits are all distributed evenly, with the implication that it is a disjunctive sequence, meaning that all possible finite sequences of digits will be present somewhere in it. If we consider π in base 16 (hexadecimal) , it is trivial to see that if this conjecture is true, then all possible finite files must exist within π. The first record of this observation dates back to 2001.

From here, it is a small leap to see that if π contains all possible files, why are we wasting exabytes of space storing those files, when we could just look them up in π!

iPhones Benefit Google More than Android

As much as Apple will benefit from getting new customers with an entry level iPhone that benefits their ecosystem so will Google. We know Google makes more on iOS than Android and interestingly an entry level iPhone will likely help Google’s bottom line as well.

On Being Apple-y

After yesterday's post on "Being Googley" what better than a post on "being Apple-y"?

On Being “Googley”

The Meanings of Googliness talks about what it means to be a Google employee.

Uh, yup.

Siri in iOS 7 – Still Can’t Spell My Own Damn Name Properly

Siri takes initiative to learn how to pronounce names in iOS 7.

Great. Big freakin' deal.

Siri still can't spell the word "Erik" any way other than "Eric," on my phone or the phones of my friends, and there's no way to teach it to do so.

If your name is Michele with one "l"? Tough beans. You're out of luck and perpetually doomed to have your phone, who knows you are the contact and who can pronounce your name just fine, constantly misspelling your name.

Read Receipts

Ars writer Casey Johnston on Why I hate read receipts:

The cases above are real, but it's safe to say that most messages are written to be responded to. Therefore, when someone doesn't respond to your message, it can be a blow to your ego. What was wrong with what you said? Too flip? Too harsh? Too dumb? Too boring? Has the conversation been boring the entire time and you didn't notice? Have you been bored this entire time but just didn't have the wherewithal to end the conversation first? Curse that other person for being braver than you and cutting ties first! You are now the hanger-on, just slightly more desperate than before.

A commenter adds:

The fact that I know if someone got my message to pick-up something important while they're in town is far, far more valuable to me than the potential for some BS social awkwardness as the author suggests.
