You’ve decided that you want to downgrade the iOS software on your iPhone or other iOS device. Depending upon the particular device you own and iOS version you are running, your ability to do a downgrade can vary from slightly tricky to virtually impossible. This is because Apple has done its best to prevent downgrading.

Montreal band develop album art in the digital age, providing bonus material to accompany the download of their latest LP. "The idea is simple… Tightly sync a series of images with specific moments in a song using the m4a format. Like some podcasters do, but with micro chapters for each lines of the lyrics. In addition to that, we were able to add good old hyperlinks also synchronised to the song. This gives the possibility for the band to add, at any moments, all kinds of references related to each song. They plan to change and update those links occasionally."

This post describes some techniques that may help you optimize your PNG-images. These techniques are derived from laborious hours spent on studying how exactly the PNG encoder saves data. We’ll start with some essentials about the PNG format and will then move to advanced optimization techniques.

Ever since Tweetie 2, the pull-to-refresh paradigm has been a hot feature for iPhone applications. The idea is that you can pull down on a list of items to refresh them. This saves you from needing some sort of "refresh" or "reload" button. Nice!

WebKit now supports alpha masks in CSS. Masks allow you to overlay the content of a box with a pattern that can be used to knock out portions of that box in the final display. In other words, you can clip to complex shapes based off the alpha of an image.

Anyone remember Color cycling from the 90s? This was a technology often used in 8-bit video games of the era, to achieve interesting visual effects by cycling (shifting) the color palette. Back then video cards could only render 256 colors at a time, so a palette of selected colors was used. But the programmer could change this palette at will, and all the onscreen colors would instantly change to match. It was fast, and took virtually no memory. Thus began the era of color cycling.

This demo is an implementation of a full 8-bit color cycling engine, rendered into an HTML5 Canvas in real-time. I am using 35 of Mark's original 640×480 pixel masterpieces which you can explore, and I added some ambient environmental soundtracks to match. Please enjoy, and the source code is free for you to use in your own projects (download links at the bottom of the article).

Useful utility to create htaccess redirect rules interactively.

Among other things:

* Removed more freedoms and civil liberties for Americans than any other president in US history.

* In a little over two years created the most divided country in decades, possibly the most divided the US has ever been since the civil war.

* Entered office with the strongest economy in US history and in less than two years turned every single economic category heading straight down.

We all underestimate our ability to massively change our life when it's gone off track.

If you’re an iPhone Dev, and you’re not using Twitter, you really should be.
Whatever else Twitter may be, it is a wonderful, anarchic repository for random bits of incredibly useful information. A good habit to get into is marking useful tidbits as favourites so that you can come back to them later.

Making tools to create & edit game levels.

Have you ever thought “I wish there was a way to click a link in an email and launch my app…” Well there is, through the magic of custom app URLs. The basic idea is this: register a custom URL protocol with the iPhone, and if someone clicks a link with that protocol on that device, it will launch your app. But wait, there’s more: because it’s a URL, you can pass parameters into the app on launch.

This is what I'm trying for in my new place.

One of the coolest portfolios I've ever seen.

AppleScript to import from Things to OmniFocus

Applications running on devices with large displays (iPhone 4 and iPad) may want to render at a lower resolution than the devices' native resolution for better performance.

Biggest non-story ever. I love how the right wingers get their panties in a bunch over a non-issue like this yet they completely ignore all of Bush's illegal acts.

This is epic.

Florida Department of Transportation officials are trying to determine how someone altered a couple of digital construction signs along the Palmetto Expressway to flash "No Latinos" and "No Tacos" on Tuesday morning, WPLG-Ch. 10 reports.

Despite its ease of use, or perhaps because of it, UIImage suffers from some serious limitations. Key among these is its lack of support for resizing the image, a feature that is normally handled dynamically by its companion, the UIImageView component. However, should an iPhone application need to reduce the size of an image for storage or for exchange with an external entity (such as a web server), the UIImage class is insufficient.

The cocos2d-iphone game engine is the premier 2D game engine for iPhone game developers. Sometimes, it can be a tough nut to crack. You may also find yourself struggling with Objective-C, Xcode, Cocoa Touch or the iPhone SDK in general, including Code Signing and App submissions. This website is dedicated to cracking the cocos2d nut and getting your game out there!

Predictably, people’s initial reaction was “Wow, that’s the new iPad!” But that quickly faded as I opened the Photos app and passed the device around. My family was more interested in sharing the photos than talking about the new technology.

I was particularly interested in how my mother, the quintessential technophobe, would react to the device. She picked up on things quickly and was flipping through photos in no time. It astonished me how the interface disappeared for her: at one point she subconsciously licked her finger before “flipping” to the next photo.

Apple telling Adobe to go f*** themselves -

"Flash is a cross platform development tool. It is not Adobe’s goal to help developers write the best iPhone, iPod and iPad apps. It is their goal to help developers write cross platform apps. And Adobe has been painfully slow to adopt enhancements to Apple’s platforms. For example, although Mac OS X has been shipping for almost 10 years now, Adobe just adopted it fully (Cocoa) two weeks ago when they shipped CS5. Adobe was the last major third party developer to fully adopt Mac OS X."

Los Angeles actor, D.C. Douglas, says he was dropped from the upcoming GEICO "Shocking News" campaign after a group of Tea Party members harassed him and the insurance giant over a private voicemail the actor left for FreedomWorks. Matt Kibbe, President and CEO of FreedomWorks, posted Mr. Douglas' cell phone number in a blog post on biggovernment.com, instructing readers to "Feel free to contact (him)… call his employer too. Let them know that you…are now in the market for car insurance." The next day, GEICO held auditions to replace Mr. Douglas' voice on the campaign.

Really great photography
