Thanks to author and programmer Mike Ash for this developer-focused explanation of Apple’s move to the 64-bit A7 chip in the iPhone 5s. In short, although details will vary by app, 64-bit code that takes advantage of new programming techniques can be faster and use less memory (though 64-bit apps use more memory in general). Plus, old 32-bit code can run on the A7 with no changes or performance penalty.follow link
Fill in Gaps in Pear Note
If you ever find yourself zoning out during a meeting or class, only later to realize that you forgot to take notes for 20 minutes, Pear Note makes it easy to fill in those gaps. To do so:
- Open your Pear Note document.
- Hit play.
- Click on the last text you did type to jump to that point in the recording.
- Click the lock to unlock the text of the note.
- Take notes on the part you missed.
Your new notes will be synced to the recording just as if you'd taken them live with the rest of your notes.
