Riverfold Software — my friend Manton Reece — just released Tweet Library (iTunes link) on the iPad.

It's another Twitter client, yes — but it does a bunch that the other ones don't. It archives your tweets and provides filters and collections. Is Twitter important to you? You may need this.

There's a website that talks more about it — with screenshots and an intro video.

One of the cooler features: you can publish a collection of tweets to tweetlibrary.com. Lately I've been thinking about web-based features like that for my own software — so it will be interesting to watch tweetlibrary.com and see how it goes.

Congrats, Manton!

TouchUp (iTunes link) is a gorgeous new photo editing app from my friends at RogueSheep. Introductory price is 40% off, just $2.99. I love it. Totally fun app. I had seen betas, but hadn't had the chance to use it much until just today. I'm impressed by their work, as usual...

In RogueSheep's recent post on Scholarly Shepherding, Chris talks about the UW Extension course on Cocoa. Though I'm not one of the teachers, I'm on the board — and I'm hugely proud of the teachers and students and folks at UW who made the first year such a success. Year two...

I've very much enjoyed the previous 360 iPhone conferences — and the first 360 Mac conference is coming up this December. There's a call for papers — I'll be there, and I'd love to see a great line-up.

One thing that excites me about this is that the Mac doesn't have the restrictions that iOS development has. The Mac is the playground. It's where we get to have fun, where we get to try things, where things like JSTalk and MacRuby appear.

The anarchist in me remains enamoured of the Mac platform, more so than ever, and I'm super-excited for the future of Mac software. The conference could reflect that — with your help.

My co-worker Nick Harris investigates data encryption on iPhones and iPads — a topic very important to the enterprise, and a topic that should be important to every developer whose app works with private data.

It's open-source sharing code for iOS apps: Twitter, Facebook, etc. I haven't looked at the code yet, but I definitely like the idea. Good for the ecosystem.

Would be cool if it worked for Macs, too.

Jeff LaMarche: "The other day, I saw somebody wearing a T-shirt that said 'Dance Like Nobody's Watching.' I'm not much of a dancer, but I like the sentiment. However, dancing is not coding. The worst thing you can do is code like nobody's watching."

Jeff makes a great point. I might sum it up as: do it right the first time, no matter what the pressure — it always pays off.

(I play a guest role in the addendum. The follow-on point being that code reviews — actually having people look at your code — are good too.)

At WWDC I called Jeff the "smartest guy in iPhone development." If you're a developer, you should subscribe to his feed. (But I bet you already have.)

Cocoa with Love: "But the classification of an application isn't a simple tree structure — there are many different connections. And the connections aren't simply of heredity — there are subclasses, view hierarchies, event hierarchies, control hierarchies and more."

Sometimes when I just want something good to read I go through the Cocoa with Love archive. I even read articles I've read before.

furbo.org: "It's no secret that 'multitasking' is one of the great new features of iOS 4. Unfortunately, many people have a misconception about what Apple has implemented."

Brad Feld: "Ross (my IT guy) bet me $100 that I'd beg him to ship my Windows desktop to me within a few days of getting to Alaska. Help me win the bet."

Matt Legend Gemmell: "Your customer doesn't care about any of the other crap that you want to throw onto the product page. Get rid of it; put it elsewhere."
