C4 posts

C4[1] videos now being posted

by Mat Lu (RSS feed) on Feb 10th, 2008

Back in August famed Mac developer Jonathan "Wolf" Rentzsch organized the C4[1] conference for independent Mac developers in Chicago. The presenters included a veritable who's who of indie Mac developers and now Rentzsch is getting around to posting videos of the presentations for those of us who weren't fortunate enough to attend in person.

Apparently it takes a considerable amount of time to process the video, so he's only posting one per week for the next several weeks. Nonetheless, he already has his own introductory video as well as one by Wil Shipley (of Delicious Library) on marketing hype. As you can see from the original schedule, future videos will include presentations from a bunch of TUAW's favorite devs.

So, if you're interested in the Mac indie development scene you'll want to keep an eye on Rentzsch's video page over the next few weeks.

Mirror-enabled videoconferencing on the iPhone

by Mike Schramm (RSS feed) on Aug 13th, 2007

The iPhone application community continues to amaze me-- this time, Engadget's got the heads up on an iPhone video conferencing system, made possible by not only a cool little piece of code (designed for a C4 contest) that fetches an iPhone's camera input and feeds it out to another iPhone via a webserver, but also these ingenious mirror settings that work as a little periscope around the phone, and let you both see the image on the front while the camera on the back grabs yours. Wild!

The Ecamm folks are old hands, apparently, at the ingenious use of mirrors around an Apple camera, but this definitely tops anything I've seen in the past. Just an amazing hack, both in terms of software and hardware. Unfortunately, the source (for either hack) isn't available yet, but they promise that something is coming soon. In the meantime, just bask in the glow of what these iPhone guys are capable of.

Thanks to everyone who sent this in!

TUAW at WWDC 2007: Interview with Wolf Rentzsch

by Victor Agreda, Jr. (RSS feed) on Jun 22nd, 2007

Wolf Rentzsch is another Mac developer so devoted to his craft that he comes to WWDC just for the fun of it. Wolf loves code so much, in fact, that he started C4, an "indie conference for indie developers." Scott sat down with Wolf to talk about Mac dev work, his own work, iPhone and C4.

NOTE: This should be the last of the "Perpendicular Subject" series, we hope you've enjoyed the side views!

C4[1] registration open

by Scott McNulty (RSS feed) on May 15th, 2007

Jon "Wolf" Rentzsch's alternative indie Mac developer conference C4 is once more upon us. Registration is open for the event which takes place Aug 10-12, 2007 in Chicago. The 3 day event costs $512, which includes meals, and features talks from the likes of Adam Engst, Cabel Sasser, Daniel Jalkut, and Wil Shipley to name a few (check out the full schedule).

There are 3 student scholarships available once again this year. All you have to do, if you're a student who would like to be considered for a scholarship, is follow the directions listed here. The attendees each get three votes, which they will use to pick which 3 applicants will receive the scholarships.

This conference is intentionally small, so if you're interested in attending be sure to register sooner rather than later.

TUAW Podcast #13

by David Chartier (RSS feed) on Oct 24th, 2006

This week's podcast involves Dan Pourhadi and the C4 developer shindig he attended, those exclusive Leopard screenshots we nabbed, iPod viruses and the corporate blame game, and we round off with Apple's preliminary 4th quarter earnings results. Dan and I kept things short this time around, as the podcast rounds off at just over 20 minutes and 18.6MB.

As usual, you can grab the podcast via a direct link, our podcast RSS feed or in the iTunes Store podcast directory. Enjoy the show.

Update: It seems there's a bug in our iTS feed preventing from getting this latest episode, though our other links for accessing the podcast are working just fine. We'll keep you posted.

C4 Tip: Drag-and-drop text in Cocoa apps

by Dan Pourhadi (RSS feed) on Oct 21st, 2006

During The Grube's UI presentation at C4, he pointed to one particular example of "functional inconsistency" in Apple's software: the discrepancy in results when you drag-and-drop text in Carbon apps (TextWrangler, AppleWorks, etc.) vs. Cocoa apps (TextEdit, Safari, etc.).

When you select text in Carbon applications, you're able to drag the text by simply clicking the selection and dragging it. In Cocoa apps, however, you need to click the selected text and hold the mouse button down for a fraction of a second before you're able to drag it. Your cursor changes from the text selector to the pointer. But clicking and immediately dragging results in you re-selecting the text.

The Cocoa differentiation is a result of NeXT designing a way to enable both dragging and re-selecting, which was carried into OS X.

It's a minor inconsistency, but has frustrated me countless times. Glad that's all cleared up.

Thanks John!

"Wolf" Rentzsch announces C4: Chicago Mac Developer Conference

by Dan Pourhadi (RSS feed) on Sep 11th, 2006

When ADHOC/MacHack went bye-bye last year, the Mac development community was aching for something to fill its Big Foot-sized shoes. Drunkenbatman threw his hat into the ring with Evening@Adler, which I thought was a huge hit.

And now Jon "Wolf" Rentzsch is taking it one step further by hosting a three-day, session-packed developer conference in Chicago, with presentations from some of the Mac dev world's Most Notable (including Brent Simmons, Gus Mueller, John Gruber, drunkenbatman, and many more!).

Jon has the full schedule on his blog, and you can look at the conference in more depth at its website. There are only 75 attendee spots, most of which have filled, but Jon tells me there are still a few openings: so register quick! I'll certainly be there, and will post a recap of the whole thing here on TUAW.
