What do you mean? By default, both Thunderbird and Mail.app should fully download and locally save an archive of your mail.
To verify this in Thunderbird, check out Tools -> Account Settings, then go to the "Synchronization & Storage" page. Make sure it's set to "Keep messages for this accounts on this computer," "Synchronize all messages locally regardless of age," and "Don't delete any messages." You can click the "Advanced..." button if you only want to sync certain folders.
To force a sync, you can go to File -> Offline -> Download/Sync Now, but you shouldn't ever have to do that with the above settings.
Has anyone compared this to the Skeleton responsive grid? I like that the styling on skeleton is more minimalist, but worry that I'm missing on some features from Bootstrap.
Seeing that the designer/developer of Skeleton (@dhg on twitter) is a designer at Twitter now, I'm sure there will be plenty of mash-ups between Bootstrap and Skeleton.
At least, it gives me something to hack on this weekend :D
They are different. In months past I have been mashing up components of bootstrap with skeleton (as well as 2 excellent others, golden grid system and frameless by @jonikorpi) in order to have sensible css defaults that work responsively. GGS made some things possible without modification that were very tough to implement in skeleton (like the footer at the bottom of goldengridsystem.com)
You're worried that it's missing some features? Skeleton has no features. It's a grid, some typography, and some defaults. On the other hand, Bootstrap is a complete front-end package. They're very different. Look at Bootstrap's js bundle alone.
Skeleton is nice when you just want some sensible defaults with your responsive grid.
Does anyone know what this switch implies for Patriot Act information requests? I had heard that the UC puts up some resistance to the FBI when asked for user data, and that Google does less so.
