how to Use Coffee Grounds To Cover Furniture Scratches



Although we’ve recently shown you how to use a walnut to cover scratches in furniture that needs a little love, some weren’t big on the idea due to nut allergies. Although the risk in the idea might be small, there’s another way you can buff out those nicks and dings… coffee grounds!

Mike Lieberman from 365 Ways To Go Green shows us how to apply used coffee grounds with a cotton swab to help cover those unsightly scratches. This is a perfect trick for those with medium-dark furniture as the coffee is slightly darker than the walnut oil we had been using previously.

We would suggest that after the application, you let the grounds sit for 5-10 minutes before buffing things with a cotton rag to ensure you won’t end up with coffee pants next time you sit down — because no one will believe you that it’s coffee and not something else.


Sony to launch flash cards with 125 Mbps write speeds

Electronics giant the first to launch memory cards under new XQD standard.

Sony is to begin selling memory cards with write speeds of 125 Mbps, the fastest in the industry, from February.

The new cards are the first to be announced under a new standard called XQD, a specification from the CompactFlash Assocation announced in December.

The cards are meant for working with data-heavy formats such as raw image and video data in high-end cameras, where write speed to memory is becoming a bottleneck as image sensors and processors become more advanced. Faster write times will mean less pause between pictures snapped in data-heavy formats such as RAW, and snappier editing for previously saved data.

Sony said it will launch 16 GB and 32 GB versions initially, as well as readers that work with USB 3.0 and PCI slots in computers. In Japan, the cards will have estimated prices of ¥20,000 (£167) and ¥33,000 (£276), while the readers will each cost ¥4,000 (£33) and are slated to go on sale Feb. 15.

A Sony spokesman said the products will also be released outside Japan on a similar time frame.

CompactFlash is an older rival to formats such as Secure Digital (SD) which is now widely used for storage in mainstream digital cameras, mobile phones and personal computers.


Microsoft Aims Windows 8 Storage At Enterprise Data Centers

Windows 8 includes a storage scheme suitable for business deployment that can treat hundreds of disks as a single logical storage reservoir and ensures resiliency by backing up data on at least two physical disks.

Network World — Windows 8 includes a storage scheme suitable for business deployment that can treat hundreds of disks as a single logical storage reservoir and ensures resiliency by backing up data on at least two physical disks.

Called Storage Spaces, the feature sets aside a designated storage area — called a space — for a defined category of data within the entire available disk capacity — called a pool.

MORE WINDOWS 8: Windows 8 can scrub data from disks, but not up to tough security specs

Pools are treated as single virtual disks that can be partitioned and formatted as if they are single physical disks, according to the MicrosoftBuilding Windows 8 blog. Spaces are defined across multiple physical disks, and the physical disks can still be treated as one even if they vary in size or are connected via different interfaces such as USB, Serial ATA (SATA) or serial attached SCSI (SAS).

Storage Spaces has advantages that make it suitable for business deployments, writes the author of the blog, Rajeev Nagar, a group program manager on the Windows 8 storage and file System team. “Storage Spaces delivers on diverse requirements that can span deployments ranging from a single PC in the home, up to a very large-scale enterprise datacenter,” Nagar writes.

One interesting feature of Storage Spaces is that it can allocate a space that is larger than the actual available physical capacity of the pool that the space is carved out of. This sleight of hand is done via a technique Microsoft calls thin provisioning, which keeps data from overflowing the space by freeing up capacity whenever files are deleted or an application decides that such capacity is no longer needed, according to the blog.

This makes it possible, for example, to create a 10TB space within a 4TB pool, Nagar writes.

Anything stored in a space is mirrored on a separate physical disk. “Resiliency is built in by associating the mirrored attribute, which means that there are at least two copies of all data contained within the space on at least two different physical disks. Because the space is mirrored, it will continue to work even if one of the physical disks within the pool fails,” according to the blog.

Storage Spaces has a second resiliency feature called parity in which some redundancy information is stored next to data in a space, so if a disk fails, data can be reconstructed automatically. “While conceptually similar to mirroring, parity-based resiliency utilizes capacity more efficiently than mirrored spaces do, but with higher random I/O overhead. Parity spaces are well suited for storing data such as large home videos, which have large capacity requirements, large sequential (predominantly append) write requests, and an infrequent-to-minimal need to update existing content,” Nagar writes.

Storage Spaces is similar in some key functionality to Windows Home ServerDrive Extender technology, it is not a one-for-one replacement, and is not backward compatible. In order to switch to Storage Spaces, users must create new pools and spaces on new disks and copy data to the pools.

Nagar writes that there are no architectural limits to the number of disks that can comprise a pool, and Microsoft tests pools made up of hundreds of disks as might be found in a corporate data center.

When the Windows 8 beta version is available sometime within the next month or so, it will include a Storage Spaces configuration tool. Those who want to try it out in the currently available developers preview must use PowerShell.

Windows 8 is the next version of the Windows operating system, now due for beta release in February. It’s expected to be generally available later next year featuring touch-screen navigation and commands as well as support for tablets. Not all apps that run on Windows 7 will be compatible with the touch-screen capabilities, but mouse and keyboard devices will enable all apps that ran on Windows 7.

The new operating system shoots for power efficiency, better security and compatibility with ARM-based chips (read tablets and next-generation PCs), all of which could make Windows 8 attractive to businesses.






































iPhone 4 10 Essential Tips and Tricks

Are you lined up to get the Verizon iPhone 4 when it debuts later this week? Don’t miss’s tips on how to dodge the number one killer of iPhones, extend battery life, manage apps and more.


CIO — You soon-to-be Verizon (VZ) iPhone 4 customers can learn from the experiences of others. Take it from iPhone old-timers, you’re about to enter a magical world of awesome apps running on the most simplistic, addictive device on the planet.

Sure, the possibilities are endless. You can leave your clunky laptop and digital camera at home. You can video chat with friends on FaceTime. You can spend hours on social networks. You can even knock down an entire building with a single Angry Bird.

Now here’s the kicker: The iPhone, dear readers, isn’t perfect. There are plenty of pitfalls to avoid, tips and tricks that come in handy, and important apps and peripherals to buy. You can either learn them on your own the hard way, or read them here.


1. Avoid the App Addiction

Quick, what’s the first thing most new iPhone owners do? They download a ton of apps, of course. Free apps. Apps for a buck. Game apps. Apps and more apps. Now with iOS folders, you can download even more apps on fewer home screens.

Most iPhone owners will tell you, though, that they’ve deleted more apps than they have on their phones. The over-under is 48 hours – that is, will a new app be opened again after 48 hours? Game apps are the worst. It doesn’t take long to finish a game or get bored of it, yet game apps can clutter your iPhone screens.

Remember, a game folder (or any folder) can only hold 12 apps, although you can have multiple game folders. Most of the game apps cost a few bucks, too. Out of pure fright, I’ve avoided adding up how much I’ve spent on apps last year, especially ones I deleted after a short time.

Another problem with having too many apps on your iPhone is when you do a routine update on the App Store. You might find yourself in a virtual waiting room as a bunch of apps update over 3G.

That’s not to say that there aren’t some very important apps that you should download immediately. See my list of 15 must-have iPhone apps, such as Siri, Instapaper and CNN. One app that wasn’t on the list but should have been is Dropbox. This app is a free file folder in the cloud, which means you can access files from any device with an Internet connection, such as an iPhone, iPad, PC or Mac.

2. Preserve Battery Life

If you’re new to the iPhone (or any smartphone), the first thing you’ll notice is that the battery life is dreadfully short. While the iPhone 4 battery is much better than previous iPhone models, it still draws a lot of power and can get really hot. You’ll have to charge it every day, and maybe more than that.

Once you become dependent on the iPhone, a dead battery will be like a best friend deserting you in a time of need. You’ll no doubt suffer the five stages of grief: denial and isolation (I’m so alone without Facebook); anger (Apple (AAPL) has got to build a better $%&@ battery!); bargaining (if I can just have a little more juice, I promise to stop playing Angry Birds); and, finally, acceptance (I can’t live without my precious).


Many tricks help preserve iPhone battery life, but they all come down to a single idea: You must now be mindful about something that you didn’t need to worry about before.

First, you should make the percentage of remaining battery life appear next to the battery icon on the upper right corner of the iPhone screen. To do this, tap Settings–>General–>Usage–>Turn on Battery Percentage. A numerical percentage helps you check the battery regularly, as opposed to suddenly being surprised by a red battery icon.

Next, disable power-hungry features such as Wi-Fi, Notifications and Location Services until you’re ready to use them. These apps reach out to the 3G radio and consume power.

The LCD is the biggest battery hog, so you will want to manage the brightness. We recommend turning on auto brightness. Go to Settings–>Brightness–>Turn on Auto-Brightness. Don’t forget to turn off Auto-Brightness when watching a movie on your iPhone 4, or else the movie will appear dark.

The overall life of your iPhone battery is constantly degrading. Every time you go through a charge cycle on your iPhone, you’ll permanently lose anywhere from 30 seconds to a minute of battery capacity. Typically, you’ll get 250 to 500 charge cycles before a lithium ion battery has outlived its usefulness. So if your iPhone is near a charger, plug it in so it’s not running off the battery.

(A charge cycle covers the entire capacity of the battery. For instance, if you drained a third of the battery and recharged it, and then used two-thirds of the battery the next day and recharged it, this would still be considered a single charge cycle.)

3. Avoid the Top Enemy of the iPhone: Water

Trust me, you don’t want to learn this lesson the hard way.

Act One: Washed Up and Ruined

It’s Memorial Day weekend, and we’ve gathered at the old folk’s home in sunny Walnut Creek, Calif., about 20 miles east of San Francisco. Three days of bliss, or so I thought.

I’m sitting in the backyard patio listening to the soothing voice of the late Hawaiian singer Israel Kamakawiwo’ole in his rendition of Wonderful World, while smoking an apple-bowl pipe with sweet smelling tobacco.

Suddenly, the Old Man comes outside and says the saddest, nastiest, most dastardly words ever told to an iPhone owner.

Old Man: “Um, Tom, your iPhone was in the washing machine.” (That’s right, I still occasionally do my laundry at my parents’ house. So what?)

Me: “What?”

Old Man: “I heard something banging around…”

Me: “What did you say?”

Old Man: “The grief that does not speak whispers the o’er-fraught heart, and bids it break.” (Okay, he didn’t really quote Shakespeare’s Macbeth; I just don’t remember what he said.)

Apparently not interested in listening to Wonderful World, the Old Man exits the stage and I’m left to figure out exactly what happened. Then it all comes crashing down. The iPhone and all my pretty apps have been destroyed in one fell whirl of the washing machine.

I lean back in my chair and utter the lonely words, “My Precious.”

Act Two: Got Rice?

A flurry of cussing follows, which can’t be quoted here. Chaos and finger-pointing ensue. Blame is quickly dealt to the appropriate parties. I’ll have to buy a new iPhone. Is the Apple Store open on Memorial Day? How much is it going to cost?

Then my older brother, a NASA engineer, enters bearing false promises.

Brother: “I just researched this on the Internet. I know how we can save it. People have done it—with rice, Tom.”

Me (after a long pause with an incredulous expression, as if to say, “How much does NASA pay you?”): “I guess you didn’t read my story about water being the death knell of the iPhone.”

For those of you too lazy to click on the link and give me a page view, here’s the important part:

One reader wrote to me that Apple refused to fix her broken iPhone because the Apple technician saw a red line on the base of the phone where the charger attaches. “It’s some kind of liquid submersion indicator,” she says, adding that her new iPhone was never exposed to water, rain or humidity. “They insisted I must have somehow submerged the iPhone in water, voiding all warranties.”

When an iPhone gets caught up in the washing machine, you’ll probably have to kiss it goodbye. “This all-too-common cause has a high mortality rate due to the thorough and prolonged penetration of the water,” says Aaron Vronko, CEO of Rapid Repair, an iPod and iPhone repair shop.

But my brother insists.

Using a tiny screw driver, he removes two screws at the base of the damaged iPhone. He gets a cheap suction cup from his car (the kind used to hold up a sign like “Baby on Board”) and removes the iPhone glass. I have to admit, I was surprised at how easy the iPhone could be taken apart.

He then places the iPhone pieces into a bowl of uncooked rice, which he says will pull out the water. We leave it overnight—a restless night for me.

In the morning, the iPhone is bone dry, the rice having done its job. I put it back together and send a charge through it. Nothing happens. I take it apart again. One half of the iPhone starts playing a song (no, not Wonderful World). After


Water will kill an iPhone faster than Clint Eastwood guns down bad guys in a Dirty Harry movie. Worse, Apple has a way of knowing if an iPhone has suffered water damage, which voids the warranty.


Rain? Danger. Washing machine? Double danger. Kyle Wiens, co-founder of iFixit, a Web site that provides free repair manuals and advice forums, has heard it all. One common water accident is iPhones falling into toilets. “People go into great detail about the water damage, like what kind of wine was spilled,” Wiens says. (See Five Strange Ways iPhones Die.)

You might want to invest in a case that guards against water, such as the Dry CASE DC13, Overboard Waterproof Case, Pelican i1015, or Magellan ToughCase. Some case makers, though, are still working to come out with a version that’s compatible with the Verizon iPhone 4.



If water is an iPhone’s public enemy number one, then the second is concrete—as in an iPhone glass screen shattering upon impact. The iPhone 4 is especially susceptible to glass breakage. SquareTrade, an iPhone warranty provider, reported last year that iPhone 4 screens break a whopping 82 percent more than iPhone 3GS screens.

There are a few reasons for this. For starters, the iPhone 4 has glass on both front and back. More importantly, the iPhone 4 glass extends to the edges of the phone. A fall on concrete will likely shatter the glass because the glass directly takes the impact. The iPhone 4 glass is also extremely hard, which makes it more breakable.

So here’s what you can do: Buy a shock-resistant case or screen protectors for the two glasses. Apple stopped selling screen protectors because the iPhone 4 screens are highly scratch resistant. But Worth Ave. Group, an insurer of consumer electronics, found that screen protectors (still available from third parties) prevent screens from shattering. Or you can just be more mindful when handling your iPhone 4.

4. Careful With That Cord

Apple’s flimsy connector cord breaks easily, so handle with extreme care. Don’t pull the cord to disconnect from the power outlet or USB port. Despite your best efforts, you’ll likely have to buy a new one every year. It’s amazing that Apple can’t build a better cord.

5. The Screen Shot Trick

Tapping the home button and on-off button at the same time will take a screen shot that’s stored in the camera roll. This feature doesn’t sound very useful, but you’d be surprised how often the screen shot comes in handy. Also, in Safari, you can tap and hold an image to save it.


6. Get a Grip on Data Plan Usage

Reset stats to track your data usage by tapping Settings–>General–>Usage–>Reset Statistics. Verizon currently offers its $30 unlimited data plan for a limited time. Verizon will soon follow AT&T with a usage-based plan. You’ll probably gobble up more data with your iPhone 4 than you think you will, so it’s a good idea to get a handle on how much data you use before Verizon makes the switch.

7. Leave Enough Memory Free

You’ll be surprised how quickly your memory fills up, especially if you’re an iPhone movie buff. Renting movies on iTunes can also take up tons of space. Leave at least a half gig of headroom to handle spikes in memory use. This will prevent apps from crashing and Web pages from freezing up.

8. Avoid No-Name Car Chargers

Charging up your iPhone using a car charger can get a little dicey. Truth is, a car’s 12 volt electrical system wasn’t designed to handle the loads of today’s cars and can fry the iPhone’s main board. If you’re going to get a car charger, buy a brand-name charger that has a better fuse to protect the iPhone. Also, don’t have the iPhone plugged in when you’re starting or turning off a car because that’s when electrical spikes occur.

9. Set a Password

The most basic rule of iPhone security: Set a password (or passcode) lock on your iPhone. The first time you leave the iPhone in a public place, or lose it in the airport, you’ll be very glad that no one can access your little personal data factory, because it’s password-protected. To set a password, tap Settings–>General–>Passcode Lock.

By the way, if you get work email from an Exchange server on your new iPhone 4, you’ll have to enter a password to unlock the phone when it’s in sleep mode. The option to turn the password lock off won’t be available. Don’t panic, it’s a tradeoff.

10. Lock The Screen in One Orientation

Locking the screen in portrait orientation is great when reading in the prone position. Simply double-click the Home button, swipe left to right on the multitasking bar until the iPod and controls show up, then tap the orientation icon on the left to lock and unlock it.
