SpiderOak Offers 2GB of Free, Cross-Platform Backup [Featured Download]

Source: http://feeds.feedburner.com/~r/lifehacker/full/~3/336084409/spideroak-offers-2gb-of-free-cross+platform-backup


Windows/Mac/Linux (All platforms): Online backup utility SpiderOak is notable for its true cross-platform availability, but it also offers (like Mozy) 2 GB of non-expiring free storage space and the ability to run in the background, making persistent backups as you change the contents of any folders you want to watch. The creators boast of a compression algorithm that speeds up both uploads and restoration, and unlimited bandwidth for paying customers, but its real value comes in its simple interface and set-and-forget nature. For any user—but especially Linux newcomers—who doesn't quite feel comfortable setting up their own automated backups, SpiderOak is a viable option. SpiderOak is free to download and create a 2 GB account; each 10 GB increment after that costs about $5/month.

Top 10 Computer Annoyances and How to Fix Them [Lifehacker Top 10]

Source: http://feeds.feedburner.com/~r/lifehacker/full/~3/337200767/top-10-computer-annoyances-and-how-to-fix-them


Computers are supposed to make our lives easier, but too much of the time they can be frustrating, time-wasting, stubborn machines. From the irritating "Access Denied" message when you can't remember your 147th password, to all the useless email that clutters your inbox, to IT lockdown restrictions that keep you from getting your job done, let's take a look at 10 of the more common gripes amongst computer users and our humble suggestions for fixing them. Photo by basykes.

10. Dashboard widgets (OS X).

widget%20on%20desktop.pngIf you've got a newer or high-powered Mac that never seems to drag, then your Dashboard widgets are probably just a dandy little convenience. But those lacking memory or just sick of accidentally hitting F12 and getting their screen taken over by Dashboard could use a little help. If you just want to make the widgets go away for one session, you can install the simple Dashquit widget or use these terminal commands for the job. Killing multiple widgets, like those iterations that pop up from delivery trackers, is easier if you hold the Option key. And those looking for leaner, cleaner Dashboard can speed it up with some cache cleaning. And if you're really only hitting F12 for a single widget, try pulling it onto the desktop.


9. Remembering passwords.

password_cropped.pngYes, yes—the "duh" answer is "use Firefox to save your passwords," but even the mighty 'fox can be used more securely, and made to remember any password. For your other data, including login and encryption tools, you could try an easy universal password system, a randomizer like Diceware, or other tools like Strong Password Generator or the Password Chart. It beats trying to remember which combination of Simpsons character and three-digit number you used for that rarely-updated social network.


8. Google search result links are indirect, awkward, and too long to copy.

If you're a power Googler who's constantly grabbing image, site, and news links from searches, you know that you don't actually get the direct link from right-clicking—you get more than a 100 characters of link-tracking gobbledy-gook. True, the link will get you there eventually, but it's not exactly email-friendly, and it's an unnecessary click-through. CustomizeGoogle, one of our Top 10 Must-Have Firefox Extensions, fixes this with just one of its many, many tweaks—"Remove click tracking," found in the first "Web" set of options. You'll get nice, clean links to copy or send, as illustrated (fourth-grade style) below:


7. Hours spent re-installing Windows XP (or Vista).

top10_nlite.jpgIt's usually only 20-30 minutes from slipping in that holographic XP or Vista CD/DVD to arriving at your new-car-fresh desktop, but it's often a few hours' work getting everything customized, updated, and tweaked to your liking. With the
nLite tool for XP, or vLite for Vista, you can skip a ton of clicking and pop-up answering during installation and first boot-up—in the case of nLite, pretty much all of it. Here's a guide to slipstreaming XP Service Pack 3 into a new, automated installation CD, and the Digital Inspiration blog has a similar walk-through of vLite for Vista. nLite's also a great tool for creating a stripped-down, speedier XP for virtualization or older machines.


6. Windows Vista, in general.

02restart.pngWe really don't mean to rag on Windows in this list—in fact, let's admit that Windows Vista isn't as bad as one would believe from the common blog or news post. It does, however, have some qu! irks tha t can quickly nip at your last nerves. Luckily, fellow tech enthusiast and blogger The How-To Geek did us a solid by writing up 10 ways to make Windows Vista less annoying, each with a link to a detailed explanation over at his own site. Before you feel compelled to say it in the comments—yes, "Install XP on Your Vista Computer" is one of the tips.


5. RE: Fwd: Fwd: Email (and time-wasting email in general).

top10_fwfwfwmail.jpgThere are tons of tools to improve your own productivity and stop wasting time on useless stuff—but not everybody got the memo, as you might notice from your inbox. Your best options for dealing with chain forwards, repetitive conversations, and other email gaffes are smart filters, including a fwd filter for those "Did you know" emails from Aunt Margie and Uncle Bif. Correspondents just not getting the message? Take the next step with an explanatory email etiquette page. Need proof that wasteful messages are eating up your time? Gmail/Google Apps users can take a detailed look at the waste with Mail Trends.


4. File copying freezes and awkwardness (Windows).

top10_teracopy.pngYou've got the entire run of "The Wire" in a 20 GB folder, and you've set it up to transfer to your external hard ! drive wh ile you're at the movies. You get home, flick the monitor on, and ... well, Windows just gave up at some point, and you're ready to toss your keyboard. Free Windows add-on TeraCopy is exactly what you need. It makes file transfers faster, more consistent, and it provides realistic job times and status reports. You'll hardly notice it's there—which is just about perfect.

3. Office IT restrictions.

workplace_computer.jpgYou can understand why the tech gurus at work don't let those people install apps willy-nilly, change system settings, or check out certain web sites. You, however, are tech-savvy, responsible, and just need to IM this one client, for Pete's sake. We know your pain, and, luckily, Gina's assembled a guide to surviving IT lockdown that should get you around most IT restrictions. If you're all but chained to the default Internet Explorer and long for Firefox, you can still get some of its best features. Photo by cell105.


2. GIANT email attachments.

attachments_filter.jpgUntil a stable, easy-to-install Flux capacitor is available, you won't be able to go back in time and prevent your relatives, co-workers and goofy-humored friends from sending that "hilarious" 10 MB PowerPoint "joke." You can, however, mitigate the annoyance and damage done to your inbox. The best suggestion we've got for any nearly any account is to create a Gmail account to manage your other mail. That way, you can jump in and check your important messages, while your dedicated mail client is frozen trying to grab that huge file. You can then use tools like Gmail Drive (Windows), gDisk (Mac OS X), and GmailFS (Linux) to clear space-hogging attachments from your email accounts. Or you can just simply filter and kill giant attachments with Gmail's advanced search-and-filter tools. If you're stuck with big attachments in Outlook, there are ways of extracting attachments without having to open the actual email, using Outlook Attachment Remover or this simple trick described by the Digital Inspiration blog. The real solution? Get your friends or relatives a copy of Picasa or another photo manager that auto-magically shrinks pictures before sending. For every other file type, there's just courteous, unsolicited tech support emails.


1. All that crappy "default" software.

vlcthumb.pngWhether you're unpacking a new PC, helping out a friend, or sitting down at a new office system, you're more than likely going to find some, as Gina puts it, sucktackular software on there. S! eriously , now—RealPlayer? Pop-ups asking to renew Norton/McAfee/Symantec? Limewire, for crying out loud? We've rounded up the free, and superior, alternatives to those persistent programs, and many of our suggestions are cross-platform, open source, and do a better job than the system-dragging softs you find in the wilds of computing.


We've covered lots and lots of other annoyances, computer-based and not, during Lifehacker's run, and we're sure you've got your own software tweaks you just couldn't take anymore. What irksome issues did you have to get rid of, and how did you do it? What irreplaceable software smooths out your desktop? Hop on the couch and share the pain in the comments.

The iPhone is More Powerful Than the DS, But Sucks As a Controller [Iphone Gaming]

Source: http://feeds.feedburner.com/~r/gizmodo/full/~3/337372782/the-iphone-is-more-powerful-than-the-ds-but-sucks-as-a-controller

You know that the iPhone is powerful enough to render 3D games like Star Wars: The Force Unleashed, as well as various other ones we covered in the marathon review session, but just how powerful is it? How does it compare to actual gaming handhelds like the Nintendo DS and PSP? An EA developer put it this way. On a scale of the three, it's in between the DS and the PSP, but sliding more towards the PSP. That's right. In terms of power, you can expect to see games that look at least as good as the DS once developers get enough (read: more than four months) development time with it.

But how good is the iPhone in terms of being a game console? How good are the tilt controls for accepting input for programs that you to make small adjustments with the phone in 3D space? Here's what the same developer from EA said to better help you conceptualize its accelerometer. "Think of it as a loose analog stick...you get lots of random data." Developers need to create smoothing algorithms in order to take random data points and interpret them into a curve which can then be used as movement info. Think about the Wii Remote before the MotionPlus add-on in Wii Sports Baseball. Remember all that jiggling your bat did? Yeah, this is that.

Photonic breakthrough could mean 60x faster internet speeds

Source: http://feeds.engadget.com/~r/weblogsinc/engadget/~3/337100749/

Filed under:

Every so often, we get wind of some new "breakthrough" from a few guys / gals in a lab that promises to simply revolutionize the web. A team from the University of Sydney is the latest bunch to do so, claiming that a piece of scratched glass (or a Photonic Integrated Circuit, if we're being proper) could enable internet speeds 60 times faster than "current Australian networks." Essentially, the "circuit uses the scratch as a guide or a switching path for information," and the resulting product is "photonic technology that has terabit per second capacity." Call us when you folks get everything ironed out -- we'll be over at Sigbritt Löthberg's house.

Sony VAIO Z-series vs. MacBook Air: fight!

Source: http://feeds.engadget.com/~r/weblogsinc/engadget/~3/337117710/

Filed under:


Like we mentioned in our hands-on impressions, the new Z-series laptops from Sony are in many ways impressive, but in ultimate thinness they leave a bit to be desired. This is perhaps best demonstrated best by Journal du Geek's comparison shots here with the MacBook Air. Sure, the Z wins all over the place on specs, with Centrino 2, discreet graphics, a full-size laptop hard drive bay, and what was that? Oh yeah, a Blu-ray drive. The Z also manages a smaller footprint, thanks in part to a smaller 13.1-inch screen in that shorter 16:9 aspect ratio, but also due to its slim bezels surrounding the screen and keyboard -- something the Air could do well to take note of -- but the actual 1-inch thickness seems dramatically fat compared to its ultrathin competition. Overall, it's all about what kind of laptop you're really gunning for, but if thin is the ultimate goal, you're going to be much better off with the X300, X200 or Envy 133 on the PC side.

Legion Hardware offers advice for building the best Crossfire rig

Source: http://feeds.engadget.com/~r/weblogsinc/engadget/~3/337301453/

Filed under:


Choosing the right graphics card / chipset combo to give you the most bang for the buck is always tricky business, and even moreso when you're looking to get the most out of some brand new hardware like AMD's Radeon HD 4000 series cards. Thankfully, the folks at Legion Hardware have now stepped in to help out a bit, although, as is often the case, it's not entirely a clear cut choice. If it's a bargain you're looking for though (relatively speaking), it seems like pairing an ASUS P45 motherboard with a couple of Radeon HD 4850 graphics cards (for a total of about $550) will give you enough performance to impress all but the most demanding gamer. If you want to push those benchmarks as far as possible, however, you'll have to go up to an ASUS X48 board, although even the folks at Legion Hardware question whether the mere 5% performance gain is worth the extra cost. If you want to make your own decision though, you can hit up the link below and dig through the numbers yourself.

Researcher claims to have discovered universal attack code for Intel chips: no one is safe

Source: http://feeds.engadget.com/~r/weblogsinc/engadget/~3/337345888/

Filed under: ,


Also, he says he found Intel's diary and is totally telling everybody about that one thing. But seriously, we think Kris Kaspersky is being a bit of a tease here. He claims to have found a flaw in Intel's processors that would allow a hacker to bust up on a computer using JavaScript or TCP/IP, with no regard for what operating system the computer is running... only he won't say what it is. He's planning on unveiling the attack at the Hack In The Box conference in Malaysia this October, where he says he'll show working code that can take control of computers, all of which he plans to release publicly. The attack takes advantage of known errata in chips, which most vendors have a workaround for in BIOS, but not all. XP, Vista, Linux, BSD and Mac operating systems are all vulnerable, so we all get to run around panicking until October -- unless somebody figures it out first.

Valmet Automotive announces plans to build Fisker Karma plug-in hybrid

Source: http://feeds.engadget.com/~r/weblogsinc/engadget/~3/337664472/

Filed under:


It may still be squabbling with Tesla over some allegedly stolen secrets, but it looks like Fisker is still moving full steam ahead with its Fisker Karma plug-in hybrid, with Valmet Automotive now announcing its intention to manufacturer the car en masse in Finland. As Fisker itself had announced way back when, they're expecting to churn out 15,000 of the cars annually, with the first of 'em sent to land in North America sometime in the fourth quarter of 2009, and Europeans getting theirs shortly thereafter in 2010. Apparently, Valmet was chosen to manufacture the car after an "extensive global search," with its location in Finland in particular working in its favor given that more than half of Fisker's cars are expected to be sold outside of North America.

Japan's AIST boasts of longer-life NAND flash memory

Source: http://feeds.engadget.com/~r/weblogsinc/engadget/~3/337833077/

Filed under:


As we've seen, Japan's National Institute of Advanced Industrial Science and Technology (otherwise known as AIST) is a pretty prolific place and it, along with its cohorts at the University of Tokyo, are now boasting about a breakthough in NAND flash memory that could result in far longer lifespans. The key to that, it seems, is the use of ferroelectric gate field-effect transistors (or FeFETs, pictured above) as memory cells, which apparently not only "dramatically improves" the performance of NAND flash memory, but allows it to be programmed and erased more than 100 million times. What's more, the FeFET-based memory apparently also requires less power than traditional NAND flash memory, with it able to operate at a programming voltage of less than 6V, as opposed to the 20V of current memory. Of course, there's no indication as to when any of this will find its way into consumer products, with AIST only saying that plans to design and develop the "Fe-NAND" flash memory array circuits and verify their operations in cooperation with the University of Tokyo.

Amazon Video on Demand store streams film and TV, launches today

Source: http://feeds.engadget.com/~r/weblogsinc/engadget/~3/337878357/

Filed under:

The New York Times is reporting that Amazon is scrapping its Unbox service in favor of a new online TV and movie store called Amazon Video on Demand. Unlike iTunes and Unbox, Amazon's new digital store-front will stream any of 40,000 movies and television programs to customers. According to Bill Carr, Amazon's VP for digital media, "Our goal is to create an immersive experience where people can't help but get caught up in how exciting it is to simply watch a movie right from Amazon.com with a click of the button." In this regard, the first 2 minutes of every video will begin to play when customers visit the video's product page. Movies can be purchased and downloaded to your hard drive or stored in an Amazon video library allowing you to stream the content to other (any?) Internet connected devices. Films and TV shows from "almost all the major studios and television networks" will be available for sale or rental in the US at undisclosed prices -- only Disney and its ABC subsidiary are holding out for uh, obvious reasons (Steve Jobs is Disney's largest individual shareholder).

Amazon also plans to bring the service directly to the living room through a deal with Sony (and others) which will ultimately embed store access into future Bravia TVs. For now, Amazon's VoD store will be available through Sony's $300 Bravia Internet Video Link device. The store goes beta-hot today for a limited number of "invited" US Amazon.com customers before going a liv! e later this summer.
