Webware

Firefox has a CPU usage issue and, consequently, can cause overheating problems in some laptops, particularly ultraportables. That's what I've found over the last couple of years.

But don't take my word for it. This is documented on a Mozilla support page entitled "Firefox consumes a lot of CPU resources." The page states: "At times, Firefox may require significant CPU [central processing unit] resources in order to download, process, and display Web content." And forum postings like this one about a Dell Netbook are not uncommon: "Mini9 would get way too hot."

The Mozilla support page goes on to say that "you can review and monitor CPU usage through specific tools" and describes ways to limit CPU usage, such as: "A Firefox add-on, called Flashblock, allows you to selectively enable and disable Flash content on Web sites."

Let me describe my experience. I find that tab for tab, Firefox uses decidedly more resources than other browsers--Safari, for example. And in the past (when I was actively using a Windows Vista-based machine) Firefox also compared unfavorably with Microsoft's Internet Explorer for CPU usage.

More specifically, here's the behavior as I see it. When I'm accessing sites with multimedia content such as the CNET front door, Firefox CPU usage will bounce around between 30 and 60 percent, and sometimes spike higher (80 percent and above), as indicated by the Mac OS 10.6.2 Activity Monitor.

On the other hand, the Safari CPU usage with the same pages open is much lower--typically between 2 percent and 10 percent.

My theory is that most users don't notice this because in mainstream laptops, this isn't an issue. But it can become an issue in ultraportables--typically under an inch thick--which are more sensitive to heat because of the design constraints. The ultrathin Apple MacBook Air, which I use as my main machine, is a good example.

The fan is usually an audible indicator of CPU usage issues. When I'm using Firefox and I have tabs open on multimedia-rich sites (which is par for the course these days), the Air's fan will almost invariably kick on and stay on until I close the tabs. As I write this, the fan has finally shut down after I closed the Firefox tabs (e.g, CNET front door). Those same tabs in Safari are still open and not causing any significant spike in CPU usage or fan activity.

When I contacted Mozilla, a technical support person guessed that Safari is possibly better at optimizing Flash-based sites compared to Firefox. And that may be true. However, I had similar issues before when I was using a Hewlett-Packard business ultraportable (also very thin like the Air) that were not necessarily tied to Flash usage. In short, Firefox was less efficient with CPU usage compared to Microsoft's IE 8. And the behavior was similar. The HP laptop would quickly heat up and the fan would kick on.

Finally, let me reemphasize that I'm guessing that most users don't notice this because heat dissipation is not a big issue for mainstream laptops that are not necessarily thermally-challenged when accessing multimedia-rich Web pages. That said, this has been a steady problem for me because I use ultraportables almost exclusively and has forced me to limit my use of Firefox.

Adobe Labs on Monday released test versions of two closely related foundations for Net-based applications, Flash Player 10.1 and AIR (Adobe Integrated Runtime) 2.

Flash is widely used to bring streaming video, interactive graphics, and games to browsers; AIR, with Flash built in, is a foundation for other desktop applications. Both are instrumental to Adobe's effort to stay ahead of the gradually broadening feature set of HTML and related Web standards.

Notable Flash Player 10.1 is support for not just Mac OS X, Windows, and Linux computers, but also a variety of smartphones, though that support isn't yet built in. What is available is hardware-based decoding of the popular H.264 video format, which Adobe said improves performance and saves battery life. It also supports HTTP streaming linked with Adobe's content protection technology.

A version of Flash Player 10.1 for Palm Pre smartphones is expected later this year, Adobe said, and the final version for all systems is due in the first half of 2010.

AIR 2.0, which includes Flash Player 10.1, brings tighter integration with desktop computers. For example, it can communicate with some USB storage devices, monitor multitouch user interfaces, tap into microphone audio data, render Web pages using HTML5 and CSS version 3, and use UDP networking useful for in-game chat.

The final version of AIR 2 also is due in the first half of 2010, Adobe has said.

There's a major movement afoot to rebuild the Web as a foundation for interactive applications. But Adobe Systems, whose Flash technology already plays that role as a nearly ubiquitous browser plug-in, believes its technology will stay a step ahead of the game.

The Web application folks are focused on HTML5, the next version of the Hypertext Markup Language standard used to create Web pages, along with associated standards such as JavaScript for programming. On this agenda is work to let Web applications work while offline, display video without any plug-ins, show accelerated 3D graphics, and churn away at background processing tasks that don't slow down the user interface.

Adobe is fine with that but believes programmers today are better off with Flash. It adopts new technology sooner and with consistency across browsers, said Adobe CTO Kevin Lynch.

"Innovation runs rapidly inside Flash," Lynch said. "A lot of HTML5 is looking to Flash and saying can we do that in HTML. That's great. We're able to be a leading agent in terms of exploring what's possible in the Web."

Lynch will make his case more concretely this week at the Adobe Max conference in Los Angeles, where the company plan to announce Flash Player 10.1. Along with the plug-in comes a related technology for Flash applications outside the browser, version 2 of the Adobe Integrated Runtime, or AIR.

Flash gets the Max spotlight
Flash Player 10.1 comes with support for major smartphone operating systems except the highest profile, Apple's iPhone. AIR 2 gets new abilities to act like a native application that can take advantage of resources on a computer, not just on the network. Adobe plans to release beta versions of Flash Player 10.1 and AIR 2 later this year and in final form in the first half of 2010, Lynch said.

Although the continued work is essential to ensure Flash's relevance, the technology has a position of tremendous power in the browser market. Not only is it installed in almost all browsers, its automatic update abilities ensure the most recent version spreads fast.

"Flash Player 10 has reached 94 percent in less than a year," Lynch said. "That is unprecedented in terms of innovation engine."

To be clear, Adobe isn't opposed to innovation in HTML. Indeed, the company is participating in the World Wide Web Consortium's HTML5 working group, and AIR employs the open-source WebKit browser engine also used in Apple's Safari and Google's Chrome, Lynch said.

"We see renewed innovation happening in HTML," Lynch said. "There hasn't been as much progress in that space in the last few years, and now there is. We think it's terrific."

But even with Web site design tools such as Dreamweaver in its portfolio, the bulk of Adobe's developer relations activities and programming tools are aimed at Flash and, increasingly, AIR. For example, Mozilla Chief Executive John Lilly said he hasn't seen much Adobe involvement in the HTML5 work.

A consistent foundation
Ralph Waldo Emerson once said: "A foolish consistency is the hobgoblin of little minds." But there are plenty of times when consistency isn't foolish. Programming can be one of them, and Adobe believes Flash it has a selling point here compared to HTML.

"If you look at the number of browsers and implementations, historically we've seen a lot of variation," Lynch said. "That variation looks like it will continue to happen, especially as innovation increases. The more expression that gets added, the more challenging it get to keep that consistency."

Lynch didn't mention it specifically, but Microsoft's dominant Internet Explorer plays a big role in this new Web application era. Even the new version, IE 8, has slower JavaScript than the faster-moving rivals that are moving to embrace richer Web programming technology. Programmers wanting to reach a broad audience are better off counting on Flash than on the latest Web app technologies, and the unified foundation from Adobe means the application will work the same regardless of browser changes.

"We think there's a lot of opportunity to provide a consistent experience across the browser," Lynch said.

One specific example has been video. Although HTML5 specifies a coding method that lets video and audio play directly in the browser with no Flash or other plug-in, the standard under development doesn't specify which video compression engine to use. Apple likes H.264; Firefox and Opera like Ogg Theora; Google likes both; and Microsoft hasn't weighed in at all.

Flash supports three engines, including the popular H.264, and indeed helped enable video on the Web by smoothing over difficulties that came with other technologies such as Apple QuickTime and Real Networks' RealPlayer.

Flash goes mobile
Taking the spotlight at Max will be Flash Player 10.1, which is getting the ability to run on a wide variety of high-end mobile phones, including those using Google Android, Palm's new WebOS, Nokia Symbian S60, Windows Mobile, and BlackBerry's OS--most of the important operating systems except Apple's iPhone OS.

"We are working on Flash Player 10 for all the major smartphone OSes and for iPhone, but we need Apples' cooperation to integrate Flash Player with Safari on the iPhone," Lynch said. "In the market, we've seen a lot of interest. We believe it's one of the top requests for the iPhone still. I'm hopeful we'll be able to bring flash to the iPhone over time."

Flash Player 10.1 also adds support for multitouch user interfaces, which are all the rage for good reason right now because they can enable an intuitive, direct interaction with computing equipment. There have been experiments with multitouch in Firefox, but it's a complicated issue in general since there's some contention about whether the operating system, a browser, or a browser plug-in is in charge of interpreting multitouch commands.

Adobe had a project called Flash Lite for mobile phones with less horsepower, but the future Adobe's focus is on the full version of Flash Player 10.

That poses a challenge for Adobe, because Flash programmers often have assumed the have the full processing power, large screens, and abundant memory of a personal computer. Mobile phones have impressive hardware compared to lower-end phones, but they're feeble compared to PCs, and now programmers must reckon with them, too.

"My view is there is only one Web," Lynch said. Adobe is trying to help, though: Flash Player 10.1 includes a low-power mode that slows video rendering to preserve power; an it's able to use the processor and memory more efficiently in general. For example, graphics are compressed for use on devices with small screens and a more limited colors, Lynch said.

Consequently, one popular AIR application, Tweetdeck, which provides a polished interface to the Twitter service, requires 35 percent less memory, he said.

AIR 2: more desktop integration
For AIR 2, the software foundation is getting closer to reproducing the features that software running natively on a computer's operating system can take employ. Multitouch is one example, since the software has Flash Player 10.1 built in, but another is support for USB mass storage devices--things like digital cameras or external hard drives.

"You can plug in a device like a Flip video camera, and it'll recognize the devices, generate an event, and the AIR application can talk to that devices," Lynch said. "It's further integration with desktop capabilities. That's the soul of AIR."

Also coming with AIR 2 is an ability to hand off files to software installed on a computer. For example, an AIR application that acts as a front end to files stored on Amazon's S3 online storage system could invoke Excel when a person used the AIR application to double-click on the spreadsheet file name.

Adobe plans to follow with broader USB support for other devices such as Webcams, he added. "Mass storage is our foot in the door. That's our start," Lynch said.

AIR 2 also brings the ability to listen to particular network channels called sockets or ports, which means AIR applications can be used for multiplayer games that set up instant-messaging networks among players, he added.

AIR is popular among the active Twitter crowd and boasts a sizable collection of software. And it has potential to spread farther, especially as Net-centric companies in e-commerce, the media, and social networking seek an easy way to bridge across Windows, Linux, and Mac OS X.

Despite some advantages, though, AIR provides is an answer to questions many programmers aren't even asking. Adobe will have more convincing to do before it convinces the world AIR deserves the ubiquitous status of Flash.

Adobe AIR apps are some of the best designed, most useful applications you can have on your desktop. Last month, I highlighted 10 applications to try out, if you're thinking about using AIR apps. This time around, I want to take a look at 10 apps that will make you more productive. Trust me, they will help you save some time.

Be more productive

Agile Agenda Agile Agenda is a project management tool that helps project managers keep their team on track.

Agile Agenda is quite impressive. You can add your team and input information about the tasks you need to perform. You can set priority, dependencies, when a task should be completed, and more. You can also edit milestones so you can track how the project is coming along. Most importantly, the app's fantastic design makes it easy to use.

Agile Agenda gives you the option of trying it for 3 days or 30 days, or buying a license. If you're buying one license, the software will set you back $70. More licenses reduce the price.

Doomi Doomi is an extremely simple to-do-list app that lets you quickly add items you need to complete. That list is displayed under the input box. You can set how long it should take to complete the task and mark the box next to it when it's complete. It's a simple app, but it's far more effective than writing your to-do list down.

File Furnace File Furnace is a unique app. Instead of impressing you with a nice design and several menus, the app displays a simple image of a fire. Over that, the app displays a message that reads, "Drop unwanted files here." It also features the sound of a crackling fire. As long as you follow the directions of File Furnace, and drag and drop unwanted files or directories into the fire, it permanently removes them from your computer. It's a slightly unusual app, but it's much easier to delete files with File Furnace than waste time with the Recycle Bin.

File Furnace is unique--and quite useful.

12seconds, a service that lets users tell others what they're up to in 12-second videos, announced Thursday that it has launched a new service called, 12omercial. The company hopes the service will become the "tweetable video commercial." Brand sponsors and companies will be asking users to create 12omercials on their behalf. Those who record the best video will receive "12 seconds of fame to goods and other prizes, as determined by the sponsor." All the videos can be added to Twitter, uploaded to Facebook, or embedded into a blog.

So far, 12seconds has signed on two sponsors--LG and Xobni. LG's sponsorship will go live with the launch of the site. The company is asking users to talk about the "things they do with their phones that they probably shouldn't be doing" to promote the company's new device, the Versa. The Xobni sponsorship will start next week.

TunesBag, a site that lets users upload music files and stream those over the Web, announced Thursday that it has launched an Adobe AIR application for Windows, Mac OS X, and Linux. The app allows users to buy tracks through Amazon and iTunes and share those songs with friends on social networks. Any songs on the user's computer can also be added to the library and played either on the desktop or through the company's online app. The TunesBag desktop app is free to download.

WatchMojo, a site that provides professionally-produced instructional videos, announced Thursday that it has hosted more than 50 million video views since its launch. According to the company, its growth has doubled in the past few months and its production costs have remained relatively stable. It expects that dynamic to continue going forward.

Business domain marketplace BuyDomains launched the company's first domain name referral program Thursday. Dubbed the BuyDomains Referral Program, the service will allow users to earn money by selling domains from the NameMedia domain portfolio, as well as sites owned by individual domain investors. Those who sign up for the program will download a configurable widget that provides consumers with access to the company's inventory of domain names. The program is live now.

Popular desktop Twitter client Twhirl has a new sibling. Seesmic CEO Loic Le Meur, who acquired the Adobe AIR-based application about a year ago, has dubbed the new service "Seesmic Desktop," which is being launched in preview as a separate product from Twhirl.

Some of the new features include the capability to monitor multiple feeds side-by-side in a similar fashion to TweetDeck, create custom user lists, and post from multiple accounts while the application keeps track of which ones are which to keep duplicates at bay. You can also drag and drop photos from your computer to post straight to Twitter, making use of the fact that it's running off of Adobe's AIR platform.

However, not all of this functionality will be available from the get-go. The service is being launched in "preview" and will support only Twitter, however Le Meur said his team is on track to release support for other services in about a month. He also said that there's a pro version on the way that should fill in the company's business model, since this version--just like Twhirl, will not contain advertising.

One thing is clear though--Twhirl's life cycle may be at an end. While Le Meur said that development will continue on it, that could simply mean bug fixes. Considering Seesmic Desktop is launching as a Twitter client from the get-go should tell you something.

Seesmic Desktop preview is available for download right now, although you've got to sign up to be a member of "Team Seesmic," the company's new community site.

You can catch the whole live blog after the break.

The new Seesmic Desktop is kind of like the old Twhirl, meets Tweetdeck--with a dash of iTunes.

Skimmer (download) is a new social aggregator powered by Adobe AIR. It supports Twitter, Flickr, Facebook, YouTube, and Blogger, and lets you stay abreast of the latest content from each of those services. Everything gets sucked up into a single stream (a la FriendFeed), which you can then sort out by service, keyword, or group of friends. Like Twhirl, Alert Thingy, and others, the idea is to casually keep an eye on all these places while getting real work done in other applications.

In addition to pulling in content, you can also use it to post to any of the included services. It has a built-in YouTube and Flickr uploader where you can simply drag in files and edit the metadata before it's sent off. It also doubles as a personal blogging platform of sorts, letting you combine your various feeds into a single page that can be customized, then embedded on a hosted page or social networking profile.

You can customize the look and feel of this page using a built-in editor, which turns all your feeds into a really slick-looking personal blog with cascading streams of information (I've embedded an example after the page break).

While the app is beautifully designed, I found the main content feed difficult to parse, which is a shame because that's all I'd use an app like this for. The Flickr photo browsing is elegant, and fast loading, but the text portions for places like Twitter and Facebook come in at a very small size. They can be resized to be a tad larger (or absolutely enormous), but the application will scale the text up and down to fit in each update slot, which makes reading hit or miss.

Skimmer organizes multiple streams of information from different services into one big feed you can filter and navigate quickly.

Skimmer has some tough competition coming out of the gate. FriendFeed recently began delving into desktop applications with its AIR-powered notifier, and existing apps like Twhirl and Alert Thingy are getting more and more services all the time. Skimmer has a chance to stand out with its Web site builder, which does a really great job at repackaging your content to go elsewhere.

Skimmer lets you create your own content widget with all your feeds. You can stick this on your blog or social-networking profile and it does all the heavy lifting.

Meebo, a Web service that lets people access instant messaging services from anywhere, announced Monday that it is launching an extension to its ad platform. Starting in the second quarter, Meebo will attempt to expand its reach across the Web by increasing the number of sites that feature integrated Meebo ads. Meebo ads will feature video, apps, games, news, quizzes, product showcases, and more. The ads will go live in the coming weeks.

AirSage, a company that turns real-time cell phone signals into traffic data for popular mapping services like Google Maps, announced that it has enhanced its traffic information and is collecting more than 3 billion anonymous locations of people every day. The service's hallmark product, AirSage Wise Location Data, is available for use through its standard API.

Keyword search company Evri announced Friday that it has cut 25 percent of its staff to help make it through the economic downturn, according to report from VentureBeat.

Wynton Marsalis, the Pulitzer Prize-winning composer, trumpeter, and bandleader, will make his new album, "He and She," available exclusively on iLike for its first 24 hours of availability, the social music site announced Monday. The album will be available all day Tuesday on iLike. By Wednesday, it will be available at other music stores.
