Tableau Public Brings Your Boring Data to Life [Downloads]

Source: http://feeds.gawker.com/~r/lifehacker/full/~3/VXZVXiFgV6Y/tableau-public-brings-your-boring-data-to-life

Windows only: Free application Tableau Public creates beautiful visualizations from your data and lets you publish them to the web, where users can interact with your charts and graphs with live updates.

The video above provides a great overview of how the tool works. Essentially, you import your data into the desktop Windows application, then play around with different charts, graphs, or other options until you find the visualization or visualizations that best fit your data. When you're happy with what you've put together, you can save the outcome to the web, which uploads the charts to the Tableau Public servers. From there you can embed it on any web page YouTube-style), and users can drill down into the data to their heart's content.

Here's an example of Tableau Public in action from a post on the Wall Street Journal:

Dashboard at 570

Tableau Public is a free download for Windows, and looks like a great tool to try out next time you're looking to make your otherwise boring data come to life. Update: Somehow I managed to miss the fact that Tableau Public ~~is only free on a trial basis; its actual price tag is extremely hefty. (Though if you're a student you can get it for as little as $69.)~~

Double Update: Actually, looks like Tableau Public is free after all! Straight from the horse's mouth:

"People can download the free tool and publish their visualizations of their data for free. Tableau Public includes a free desktop product that you can download and use to publish interactive data visualizations to the web. The Tableau Public desktop saves work to the Tableau Public web servers – nothing is saved locally on your computer. All data saved to Tableau Public will be accessible by everyone on the internet, so be sure to work only with [publicly] available (and appropriate) data.

When people want to analyze their private or confidential data (particularly data in data warehouses and other large databases), then they may want to consider our commercial products."

How to Make Your Personal QR Code [Cameraphones]

How to Make Your Personal QR Code Ever since I installed a barcode-scanning app on my phone, I see QR codes everywhere—so naturally I wanted one of my own. If you're a barcode-scanning fool, the QR code to the left links to my personal web site. Fun!

A QR ("quick response") code is a square barcode that makes getting URLs, location coordinates, any text or contact information onto a phone quickly. With a barcode scanner app installed, you just point your phone's camera at the code to read its contents. Here's what reading this QR code looks like on my Android phone, using an app simply called "Barcode Scanner."

To find a scanner application, Google "QR Reader" and the model of your phone. (If you've got a favorite scanner app that you're using, let us know in the comments.)

Encoding a regular URL is a fine use of QR codes—especially lengthy and complicated URLs on movie and event flyers—but one of my favorite uses of QR codes is swapping mobile app recommendations with your friends. Since you can't search the Android Market on the web or in desktop software, you're always stuck tapping in search terms by hand. The App Referer app generates QR codes for every one of your applications. So if you want to "give" that app to a friend, you call up the QR code, and your pal can scan your phone's screen.

You'll also see QR codes on web pages, in store windows, on business cards, and on conference badges. You can generate your own QR code with the information you want others to be able to read onto their phones quickly too. This QR code generator can embed a URL, text, a phone number, or an addressed and ready-to-send SMS message into a QR code.

If you Google "QR code generator" you'll find others, but beware of generators that force a redirect through their site when someone scans the resulting code and gets a URL. (For example, this generator has options to encode Google Maps coordinates, social network information, and Vcards and can print t-shirts and stickers from the codes it generates, but if you enter a simple web site URL it creates a redirect through the qrstuff.com site.)

Speaking of stickers, now I just need to print a few with my code to stick on my laptop, phone, and conference badges.

Microvision's Show WX laser pico projector available to buy today, will ship March 24

Source: http://www.engadget.com/2010/03/08/microvisions-show-wx-laser-pico-projector-available-to-buy-toda/

Okay, so maybe Microvision is a little late with the release of its pocketable Show WX pico projector, but we'd rather have a truly useful projector late than a useless one on time. This laser-based beaut will offer you infinite focus -- something we can vouch for having tried out the same technology integrated in a rifle -- which essentially means that no matter how much you twist or jerk the projector around, or how distant your projected surface is, the picture will remain in focus. An 848 x 480 resolution image can be scaled from less than six inches all the way up to 200, though you're most likely to stick with anything up to 30 in order to make the most of the 10 lumens brightness on offer. The contrast ratio is rated as being greater than 5,000:1 while the battery will last you up to two hours on a charge. The wallet damage is $549 for the standard edition, but the limited edition teased above jumps all the way to $999, for which you'll get a personalized splash screen, LE insignia, a certificate of authenticity, a VGA dock and some other trinkets. Come on, it has lasers inside, it was never gonna be cheap!

We've been hearing about a certain 82-inch E-board as far back as SID-2008, but recently the Samsung Roadshow launched in Germany, allowing us to finally get a good look at the device. In addition to its interactive, multitouch whiteboard functionality, this bad boy (also available in a 65-inch model) can act as a display for a PC or Mac and supports Sammy's EmoLink technology for receiving and displaying data from the company's e-readers. No word on a release date, but when it does roll around you can expect to drop about €9,000 -- or about $12,300. So start counting those pennies now! Video (in German) after the break.

Intel readies 8-core Nehalem-Ex processors for a March launch

Source: http://www.engadget.com/2010/03/08/intel-readies-8-core-nehalem-ex-processors-for-a-march-launch/

Intel's current generation of Xeon processors already represents some of the fastest silicon you can buy, and yet the company's forthcoming Nehalem-Ex-based Xeons are being touted as the single greatest generational jump in its history. To achieve that, Intel has strapped eight cores into each CPU, with a pair of threads per core and 24MB of shared cache, along with integrated quad-channel memory controllers, Turbo Boost, and the pretty awesome ability to scale up to eight sockets -- meaning you could have 64 processing cores in the same rig. Don't even ask whether these chips can run Crysis 2, they'll probably be showing up in the machines that are making the game... and maybe yours, provided you have the cash to splash later this month.

ASUS Eee PC 1005PR packs Broadcom Crystal HD and high-res screen

Source: http://www.engadget.com/2010/03/08/asus-eee-pc-1005pr-packs-broadcom-crystal-hd-and-high-res-screen/

Today in Tales from ASUS we bring you the story of the 10.1-inch Eee PC 1005PR. While we didn't catch this one hiding out in the overflowing CeBIT booth, it appears big A has gone and swapped out the screen on the 1005PE for one with a 1366 x 768-resolution and tucked a Broadcom Crystal HD accelerator inside, which means the little lappie should be able to handle some YouTube HD (at least after you download 10.1 Beta 3). Nothing special apart from that, as it's standard netbook down the line: 1.66GHz Intel Atom N450, 1GB of RAM, and 320GB hard drive. No word on pricing or availability, but we're guessing it'll probably come in at under $400, like the Dell Mini 10 and HP Mini 210. It may not be a bad deal in the end, but we're still holding out for the Ion 2-equipped 1201PN and for ASUS to someday slow down the frenetic pace of Eee PC iteration.

Android NDK hits Release 3, brings OpenGL ES 2.0 access to devs

Source: http://www.engadget.com/2010/03/08/android-ndk-hits-release-3-brings-opengl-es-2-0-access-to-devs/

We know from a brief spat of iPhone 3GS controversy that OpenGL ES 2.0 brings a new level of immersive realism to 3D gaming on mobile devices, so Android developers (and users, for that matter) should be delighted to hear that a new release of the official Native Development Kit exposes its capabilities to anyone targeting Android 2.0 or higher. As a refresher, the so-called NDK is a bolt-on to the standard Android SDK that gives folks the ability to write and compile critical pieces of functionality in native code, closer to the processor without that pesky Java virtual machine standing in the way -- in other words, it's exactly what gamers and game devs need to make Android a serious gaming platform, and better access to badass 3D capabilities are a fun little piece of the puzzle. The latest NDK's available for download now -- so seriously, hurry up and go wow us with your revolutionary first-person shooter. Git!

Google and Dish Network testing TV search on Android-based set-top boxes

Source: http://www.engadget.com/2010/03/08/google-and-dish-network-testing-tv-search-on-android-based-set-t/

We've definitely heard of a few different Android-based satellite and cable boxes in the past year, but it looks like Google's exploring a real move into living room: the Wall Street Journal reports that El Goog and Dish Network are testing a TV search service on a new box that runs on "elements" of Android. (We're taking that to mean it's a stripped-down version of the OS tailored for a set-top, not some totally crazy remix.) The box features a QWERTY remote, and users can search both Dish content and other services like YouTube, which sounds like the same riff TiVo's trying to pull off with the Premiere. Unfortunately, none of this seems destined to hit consumers anytime soon -- the WSJ also says the trial "is limited to a very small number of Google employees and their families and could be discontinued at any time." Okay, but can we at least get some hands-on pictures first?

[Thanks, Jordan]

Research and Development: Apple vs Microsoft vs Sony [Graphs]

Source: http://feeds.gawker.com/~r/gizmodo/full/~3/fCC_TUnak8c/research-and-development-apple-vs-microsoft-vs-sony

The core of any long-standing technology company is research and development. Here's how Apple, Microsoft and Sony's last decade of spending stack up.

Note that the first graph shows research and development as a percentage of revenue (to scale the spending by company, since revenues differ so greatly). This next graphic can help you conceptualize the revenue and R&D gap:

A Few Interesting Notes:

• Now, Microsoft spends about 17% of their revenue on R&D. Sony spends about 8%. Apple spends less than 4%.

• If you were to break down the amount of R&D that goes purely to physical (non-software) products sold by Apple and Sony, Sony would spend about $11.5 million per product while Apple would spend about $78.5 million per product. (Of course, that's rolling the cost OS X and iPhone OS development into Macs and the iPhone, which could be seen as inflating their per product spending.)

• Microsoft just spends a lot of money in R&D, period—about $9 billion last year in generalized research (that often doesn't lead to specific products). In terms of percentage growth over the last decade, Apple's R&D has grown the most (nearly quadrupled) while Sony's has grown the least (not quite doubled).

In light of these bare numbers, is it any surprise that Sony is struggling the most to capture the hearts and minds of a public hungry for gadgets?

Air Video, the Best iPhone Video Streamer $3 Can Buy [Lifechanger]

Source: http://feeds.gawker.com/~r/gizmodo/full/~3/zCozdiTpvSk/air-video-the-best-iphone-video-streamer-3-can-buy

Air Video, the Best iPhone Video Streamer Can Buy Media streamers aren't exactly new, but there's another entrant to the field that works so simply and easily it should be nearly mandatory for any iPhone user. It's called Air Video—and it's only three bucks.

Here's the scenario: I've got a NAS with about a terabyte or so of video sitting on my network. Some torrented files, a lot of DVD rips I made myself, a fair amount of random Xvid and MKV files I've kept for years, and quite a few h.264 MPGs that I encoded of my own work.

Now, getting videos to an iPhone is relatively easy—if you want to convert them to h.264. Toss the file into Handbrake, fiddle with a few settings, and copy the converted file into iTunes to be synced to your iPhone.

Problem is, you've got to wait for the video to be converted. Then wait for it to copy to your phone. Then hope you have enough space to store it. Then delete it when you're done.

The natural solution, of course, is streaming. And several nice applications have been written that make that possible, including Orb and (which will also stream live TV if your PC has a tuner), Tversity (which can also stream to Xbox, PS3, and even DirecTV boxes). But Orb is $10; TVersity Pro is $40.

Air Video is $3. And it's so dead simple to set up that I didn't quite believe it had actually worked.

I downloaded the Air Video server software to my first-generation unibody MacBook Pro, pointed it at a local folder full of video, and activated it. (It's also available for Windows.) Then I opened up the Air Video iPhone app to find a simple directory listing. Within about three minutes from first discovering Air Video I was watching a 720p episode of a television program on my iPhone, streaming over my local Wi-Fi network.

Then I pointed the Air Video server at my NAS, suspecting that something would snag. My laptop wouldn't have the CPU power to convert the video in time. My 801.11N network would get clogged. But nope—Air Video happily chugged away, sending a real-time stream of my videos right to my phone.

I even tried watching a 13GB 1080p rip from the NAS. (Of a Blu-ray I own, thank you very much.) It worked—mostly. Air Video lost the stream occasionally, pushing the stream back in chunks as it rebuffered. Considering my laptop chokes on that file even when it's sitting on its own hard disk, I am not surprised.

Perhaps it shouldn't impress me as much as it does, but it completely changed the way I think about my media library and my iPhone. I already sleep with my iPhone at my side. And when the iPad arrives, I suspect it'll be on the nightstand, too. Now every movie or television show I have sitting around will be ready to watch in just about ten seconds.

Air Video, the Best iPhone Video Streamer Can Buy Air Video manages to be both extremely simple to use, while extremely powerful for the settings tweaker.

If a video is encoded in h.264, a format which the iPhone can play natively, Air Video simply streams it. If not, you can "Play with Live Conversion", which uses the ffmpeg library on your Mac or PC to convert the file in real-time. (Provided your machine is fast enough. Most newer computers should be able to handle that just fine.) You can also tell Air Video to do a permanent conversion of the file to a h.264, although the real-time streaming works so well I can't imagine you'd find the need to do so very often.

There are tons of conversion settings that can be fiddled with, as well as different bit rates for streaming. But the default settings and guesstimates made by Air Video work so well, I haven't yet felt the need to touch them.

You can even stream outside your network if you turn on the "experimental" Remote setting. Air Video will generate a ten-digit PIN that you punch into the iPhone app which allows it to communicate with the Air Video server even when you're away from your home network. (I suspect it is doing some sort of simple DNS-like passing of your external IP to the company's servers, although I have not investigated this.) The takeaway is that you can watch all your movies even away from home, even over 3G. Again, this isn't a brand new idea, but to have it all work so effortlessly in a $3 app is. (There is also a free version that won't display all your files at once that works perfectly, should you want to test it first.)

I've been toying with the idea of selling my HDTV for a while. I use it, but could live without it. I've barely been playing console games at all over the last few months, using the TV mostly as a giant monitor connected to a Mac Mini that serves as a home theater PC. I'd been considering replacing it with an iPad, as silly as that might seem, simply because I live alone and rarely watch movies and such with guests.

I don't know if I'll sell the TV and the Mac Mini or not, but Air Video has made me realize that if I wanted to, I could get the same functionality on an iPad. I'll never be without my video library again. Not bad for three bucks. [iTunes]

AT&T Doesn't Allow Non-Market Apps On Android-Based Motorola Backflip [Motorola]

AT&T Doesn't Allow Non-Market Apps On Android-Based Motorola Backflip Apparently AT&T is struggling a bit with the whole idea of Android, a somewhat open mobile OS. Instead of embracing it and giving users a full experience, they've decided to cripple it and not allow the installation of non-market apps.

From the sounds of it, the Android OS allows for the installation of apps "purchased on alternative markets and beta apps like Swype" by default. It's a bit of a mystery why AT&T would choose to take this option away from users, but it certainly makes AT&T's first Android-based phone even more of a letdown.

The Sum of Our Google Fears [Google]

Look, this video plays pretty loose with the facts. But there's no question that it speaks to those deeper concerns about Google: that it's so big, so invasive. And when you add it all up, the final picture's a little scary.

It's not that any one thing Google does is beyond the pale, despite serious concerns over Buzz and the EU's recent Street View intervention. But with as many businesses as Google's involved in, and as much information as they have access to, the real problem might be that the cute mantra of "Don't Be Evil" suddenly feels more like a necessary reminder.

Google's Testing A TV Search Service, Might Take Over Yet Another Device [Google]

Source: http://feeds.gawker.com/~r/gizmodo/full/~3/P1ZxAVDQ3nI/googles-testing-a-tv-search-service-might-take-over-yet-another-device

Google's Testing A TV Search Service, Might Take Over Yet Another Device Google meddles in just about everything on your phone and computer—think Google Voice, searches, Chrome, and all that jazz. Now the search engine company might hop over to your TV with a programming search service it's been testing.

According to the WSJ, Google's been testing their "television programming search service" for about a year. The project is a partnership with Dish Networks and the testing of it "could be discontinued at any time." This doesn't sound too optimistic, but a discontinuation of testing could mean many things. In the meantime, information about the project itself is also pretty scarce:

Viewers can search by typing on a keyboard, instead of using a remote control. Google hopes to link the service up with its nascent TV ad-brokering business, allowing it to target ads to individual households based on viewing and TV search data.

Google and Dish Network spokespeople did not comment on the matter so it's hard to tell what is going on and whether Google is going to pursue this particular search service further. I hope they do though, 'cause I want an "I'm feeling lucky" button for TV programming. [WSJ]
