Let's face it: Flash on the Mac is a dog. Actually, that's an insult to dogs, which are known for running fast. Flash for Mac is such a an unoptimized beast that you can expect it will suck up as much CPU as possible, even for the simplest of videos.

My first line of defense is ClickToFlash (which I've mentioned before), but the folks over at NeoSmart have another solution, at least for YouTube: HTML5.

By using the newest version of HTML, they have devised a system to send YouTube videos directly to any MP4 decoder on your computer. Simply go to their custom web page and paste the YouTube URL into the field. In a moment you will be presented with a clean window showing you the video, as well as a download link for the MP4 version.

They also have a Greasemonkey/UserScript available which will add a link to all YouTube pages. That's nice, but what I was really looking for was a bookmarklet I could keep in my Bookmarks Bar and just click on when I was on a YouTube page. I didn't find one, so I made one. Drag (don't click!) this link to your Bookmarks Bar: FlashFree YouTube and you can easily access the NeoSmart/HTML5 version.

How does it work? Superbly well. I tested it using Safari, and watching a YouTube video through NeoSmart had no noticeable impact on my CPU at all.

I've nearly given up hope for a version of Flash for Mac that doesn't stink. Until then, ClickToFlash and NeoSmart's HTML5 YouTube are a great combination to make your web surfing more enjoyable.

(Update: NeoSmart is being blocked by Google/YouTube. It turns out that if you load YouTube videos on YouTube.com while having ClickToFlash installed, they play through QuckTime, not Flash. So download ClickToFlash.)

There will be a day in the not-too-distant future when playing 3D games in your browser -- without extra plugins like Flash or Unity -- will be a reality.

The WebGL project, which has quickly made the blogging rounds this morning, combines aspects of HTML 5, JavaScript, and the OpenGL 3D drawing engine in an effort to create 3D graphics that appear right in your browser. Thus far, it's only beginning to show up in WebKit (the engine powering Safari and Google Chrome), but the glimpses as seen in the video above really show the power in these browsers.

During a recent weekend afternoon drive from Los Angeles to San Diego, I was stuck in heavy traffic -- unusually heavy considering the day and time I was traveling. Sure, I could have relied on dedicated apps, such as iPhone's built-in map app or MapQuest 4 Mobile, to see exactly where the traffic would loosen up, but I wanted to know exactly what was causing the traffic. So I turned to sigalert.com instead.

There's no denying it: locally caching messages in Gmail on the iPhone (via the storage capability in HTML 5, similar to Google Gears) is fun and good for you, especially if you don't connect to your Gmail via IMAP in the regular iPhone Mail application. Unfortunately, if the local copy of your mail gets funky, things can become difficult and much less fun.

John F. sent in this handy tip for resolving issues with cached Gmail; his suggestion is a quick dive into the iPhone's Settings app, then navigating to the Safari preferences to clear out the local database that stores the cached mail.

You may have to wait a bit the next time you connect to Gmail in Mobile Safari as the messages are re-downloaded, but any wacky cruft should be gone. While you're in there, take a look at some of the other settings options; you may discover choices you never knew you had.

Back in March I made a plea for a native Gmail application on the iPhone. As it turned out, Google was working on a new version of the Gmail Mobile site that takes advantage of HTML5 features like database storage to provide caching functionality on the iPhone and Android phones. The demo was compelling; a super-fast Gmail experience that includes long-awaited features like full label support, the ability to apply changes to multiple messages at once, and a floating action bar (dubbed the "floaty bar") that allows you to archive, delete, mark read/unread, add or remove a star, or mark messages as spam without having to scroll to the top or bottom of the thread you are viewing to do so.

The demo was certainly exciting, but though I was hoping would be released soon, I was fearing we were still a year away from seeing this new version of Gmail Mobile. Boy, was I wrong.

This sexy new web version of Gmail Mobile was released yesterday, and as a heavy Gmail user I have only one word for it: Glorious! Okay, I'm a blogger, so we know I never only have one word for something. But if you've been using the built in Mail app on your iPhone to avoid the clunky web version, it's time to try Google Mobile again.

While it's a huge, massive improvement on the previous version, the new Google Mobile is not without areas that could use improvement. For one, it is very slow to load. For me, I'm willing to put up with this since once it does load everything is significantly faster than it was. But it would certainly be nice to see an improvement in this regard, and that's something that was hinted at on the Official Gmail blog post announcing this new version. Another small annoyance is that the buttons are smaller than standard iPhone buttons, and there are more of them. It's manageable, but does require a bit of extra care and attention.

All in all, a very solid improvement, and one that makes working with email on the iPhone significantly more pleasant for Gmail users.
