"Smallest USB drive on the planet": Wink.


They claim its the worlds smallest USB drive. And it very well could be, Wink is only about an inch long and 0.1 inches thick. It may be small, but it holds a lot of memory, the tiny drive comes in 2GB, 4GB, 8GB and 16GB sizes.

Its so small that it even has a loop at the top to attach it to a keychain or a chain around ones neck. Something that small is almost guaranteed to get lost if its not attached to something. Its also water-proof and shock resistant.

The thing about this that's making the most news, isn't its micro size, but this banner on the website:





Its a pretty good idea, if you ask me. But I'm guessing Sarah's camp will find out about it eventually and it will be taken down.

Adobe Flash potentially puts most computers and users at risk



According to researchers there is a flaw within Flash that allows hackers to launch silent attacks on websites and users. Adobe hasn't tried to hide the fact that it is true and has suggested that its up to site designers to make sure they design their sites in such a way to prevent the attacks.

"The magnitude of this is huge," said Mike Murray, the chief information security officer at Orlando, Fla.-based Foreground Security. "Any site that allows user-uploadable content is vulnerable, and most are not configured to prevent this."

The problem lies in the Flash ActionScript same-origin policy which is designed to limit a Flash object's access to other content only from the domain it originated from, added Mike Bailey, a senior security researcher at Foreground. Unfortunately, said Bailey, if an attacker can deposit a malicious Flash object on a Web site -- through its user-generated content capabilities, which typically allow people to upload files to the site or service -- they can execute malicious scripts in the context of that domain.

"This is a frighteningly bad thing," Bailey said. "How many Web sites allow users to upload files of some sort? How many of those sites serve files back to users from the same domain as the rest of the application? Nearly every one of them is vulnerable."


The problem is that Adobe and security companies are trying to get the word out, but web application designers and programmers aren't listening. A few of the major sites that have actually locked down their servers to protect their users include Microsoft's Windows Live Hotmail and Google's YouTube, but sites like Google's Gmail and even some Adobe sites, still remain vulnerable. The researchers say the likelihood of an attack on Gmail is still very small, its also a very real possibility.

The only current defense users can employ against such attacks is to stop using Flash, or failing that, restrict its use to sites known to be safe with tools such as the NoScript add-on for Mozilla's Firefox, or ToggleFlash for Microsoft's Internet Explorer.

"The best mitigation is to not use Flash," argued Murray, "but we know that that's impossible for most users, since Flash is so widely used on the Web."

"Almost everyone using the Internet is vulnerable to a Web site that allows content to be updated inappropriately," said Murray. "That's not hyperbole, it's just fact. This has the potential to affect any social media site, any career site, any dating site, many retail sites and many cloud applications. That's why this attack is so serious. End users would never know they got exploited."



The best suggestion would be to get the news out about the vulnerability and hope that Adobe gets a patch to fix the problem before the slight flaw turns into a major headache for everyone.

Dell's Inspiron Zino HD

dell Inspiron Zino HD mini PCIt seems that European countries always get things us Americans want before we do, especially in the technological market. That is certainly the case with Dell's new Inspiron Zino HD mini PC. This mini PC is available already over in Ireland and even in the UK, which is driving us Americans just a little bit crazy with envy.

Now when we say that this is a mini PC, we actually mean it is a mini PC. The thing is small coming in perfectly square at 7.8" by 7.8". But just because it looks small doesn't mean it doesn't come with some incredible hardware. You can customize the heck out of this little guy and there are a ton of options. You can choose from either an AMD Athlon Neo X2 6850e, AMD Athlon X2 3250e, AMD Athlon 2850e or AMD Athlon 2650e processor to start off with. Then choose an operating system from either Windows 7 Home Premium 64-bit or Professional 64-bit, Windows Vista Home Basic 32-bit or Home Premium 64-bit or Ubuntu Linux 9.04. Upgrade your memory to as much as 8GB of 800MHz DDR2 SODIMM with either 160 GB, 250 GB, 320 GB, 500 GB, 750 GB or 1 TB of 7200 rpm SATA II hard disk space.

Among this is the optional 8x DVD +/- RW and DVDRW/BD-ROM disc drives and the choice of an ATI Mobility Radeon HD 3200 or ATI Mobility Radeon HD 4330 graphics card. All mini PCs come with the Conexant CX20561 2.1 Channel sound card and Broadcom BCM57780 10/100/1000 or Mini PCle WLAN card(802.11 b/g or 802.11 a/b/g/n). The Inspiron Zino HD comes with a plethora of ports as well. On the front of the PC are two USB 2.0 connectors, one headphone connector and one 4-in-1 memory card reader. On the back there is one microphone connector, one line-out connector, one VGA connector, one RJ45 connector(10/100/1000), two USB 2.0-compliant connectors, two eSATA connectors and one HDMI connector. In addition to all of these ports there is on Mini PCle WLAN Card(802.11 b/g or 802.11 a/b/g/n) expansion slot.

The Inspiron Zino HD as a USFF form factor with dimensions measuring 7.8 inches(197mm) tall, 7.8 inches(197mm) wide, 3.4 inches(89mm) deep and weighs 3.35 pounds(1.6kg). It has either a 65 watt with UMA or 75 watt with MXM Graphics card power source and Kensington Lock security. The Zino HD also has one 3.5" HDD drive bay, one 12.7 mm trayload ODD drive bay and two available Memory DIMM slots.

While this mini PC is completely customizable, Dell has already gone and created three different models for you already on their website. The first model has an AMD A64 2650E 1.6GHz 512k processor, Windows 7 Home Premium 64-bit operating system, 2048MB dual Channel DDR2 800MHz [2x1024] memory and 320GB (7200rpm) SATA hard drive. This model will run you around $433. The next model has an AMD X2 3250E 1.5 GHz 512k processor, Windows 7 Home Premium 64-bit operating system, 3072MB Dual Channel DDR2 800MHz [1x2048 + 1x1024] memory and 500GB (7200rpm) serial ATA hard drive with a $785 price tag. The final model comes with an AMD X2 6850E 1.8 GHz 512k processor, Windows 7 Home Premium 64-bit operating system, 6144MB Dual channel DDR2 800MHz [1x2048 = 1x4096] memory and 1TB (7200rpm) SATA hard drive with a $1,124 price tag.

What is going to catch people's eyes first is the colorful customization options you have for the shell of the PC. The Inspiron Zino HD mini PC comes with 10 interchangeable color and design shells to further your customization desires allowing you to make a truly unique piece of equipment. Despite which way you decide to take your Inspiron Zino HD mini PC you are sure to have an amazing computer. It's small size allows you to easily store it anywhere you want and still have tremendous amounts of spare space on your desk and its specs are enough to make anybody happy. But you are going to have to wait a little bit until it actually comes out in America, unless you want to go to Ireland or the UK to get one that is.

Update:

Dell's Inspiron Zino HD is now available here in America, and just 24 hours after its release across the way in U.K. and Ireland. You can now pick up your very own colorfully customized Inspiron from Dell with prices starting at $229.

New Trends: Computers Give Up CD Drives for Touch-Screens

New Trends: Computers Give Up CD Drives for Touch-Screens
A recent Associated Press report points out that personal computers are changing rapidly. It has definitely been a year of "out with the old and in with the new" as far as computers go. Laptops and Desktops are missing familiar components, slimming down and gaining lots of cool, new, unique features. Despite the popularity of gadgets such as the iPhone, PCs are still at the heart of the digital world and will likely stay that way for a while to come...even if they look and act a little differently.

One noticable change in the world of new computers is the lack of drives. Optical drives that play CDs and DVDs have been an important part of computers for over a decade. Whether you're watching a movie, listening to music, or installing software, the drives have been part of almost everyone's daily computer usage. Apple started getting rid of drives about two years ago when it first introduced the MacBook Air. Even though that wasn't a mainstream computer, due to its $1,800 pricetag, it was the start of what looks to be a popular trend. Netbooks, which are used mostly for web-browsing, start at $250 and are growing in popularity.

People are using their little laptops to download software, music and movies, while enjoying the convenience and price. The availability of Wi-Fi and cellular internet service combined with services that let you store files online are making the need for drives almost obsolete. Of course, there are the die-hard DVD watchers and CD burners who are not yet ready to give up those drives, but the lack of drives in many computers, particularly laptops does often lead to a lighter price and a much lighter load.

These days, people are also tending to purchase less powerful computers and this is another reason netbooks are becoming more popular. Everyone's been inside a retail establishment and listened to a salesperson rattle off a list of processors, graphics cards, gigabytes of memory and sizes of hard drives, but unless you're a hard-core gmer or a professional video editor, all of that stuff isn't really necessary. People are looking for computers that let them browse the web, email and use word processing applications more than anything right now.

Computer manufacturers aren't just competing with each other these days, they're also having to stand up to smartphone manufacturers, as well. People want to be connected 24/7 it seems and it's easier for that to be possible via a cell phone. "Smarbooks" are being created - think a smartphone-like device that is closer to the size of your laptop than your cell phone, and computer companies are starting to focus on laptop appearanes. Colors, patterns, themes, designs, shapes, and materials are all considered to be an important part of computer manufacturing lately, allowing users to treat their computers more like fashion accessories than tools. People also want thin and light computers that are easier to carry.

And finally, touch-screens are becoming a popular computer trend. Ever since the iPhone was developed in 2007, multi-touch has become more prominent in today's technology. The recently released Windows 7 includes support for a number of multi-touch applications and companies such as Dell and HP are designing software that allow you to browse everything from the web to your music library with your fingers instead of a mouse. And while experts say the touch-screen won't replace the mouse and keyboard, it will most likely become just as important.

What is a CD Rom? What is a CD Rom used For?

What is a CD Rom? CD is short for compact disc!

What is a CD Rom?  What is a CD Rom Used for?

Unlike the Floppy disk or the hard drive that are magnetic storage CD Roms are optic storage. They are read by a very fine laser beam. My children love to think of Star Wars when I say that! Floppy disk's lifespan can be very short, and to be honest can be very fragile! Keep in mind some floppy disks are better than others, but overall its scarey to depend on them. Magnetics can wear out quickly where as the CD rom? Its can take a licking and keep on ticking as the commerical says! Please don't take that to mean you need to abuse them. You don't want to do that either! CD Roms can wear out as well, but most of the time if you take care of them its measured in spans of 10 years or more!

Besides the durable nature of the CD rom lets look at storage space compared to Floppy disk. You can place an entire encylopedia on a CD rom. If you were to place that on Floppy disks? It would be more than 400 disks to have the same information. CD roms are cheap, durable, and hold LOADS of information!

I have a friend of mine that is intimidated by loading a CD rom into her computer. I remember asking her if she ever loaded a compact disk into her CD player, or a DVD into her DVD player? She gave me the 'your kidding me right' look as she rolled her eyes stare. (YEP I was being sarcastic at the time) I told her then you have ALL the technical expertise required to load discs into your computer CD or DVD Drive!

Be sure to handle the disc only by its edges so that you don't scratch the surface or get any dirt or finger prints on it.

If your drive has a open slot on the front of your computer for the CD rom slide the shiny side down (label on top) into the slot.

If your drive as a drive tray: Press the load/eject button on the front of the drive to open it. Then lay the disc down in the tray (shiny down, label up), and press the load/eject button again.

CD Rom This would be an example of the label. You see the title or the name of the CD rom.

CD Rom label side UP placed in the CD ROm drive!

If you ever have an issue with playing a CD or DVD it may be a little dirty. To clean the CD Rom get a small lint-free cloth. Wipe the CD Rom from the center of the disc to the outside of the disk. Don't clean in a circular motion of the CD Rom. Make sure you wipe the shiny side, and not the side with the label (it has the writing on it). The computer reads the shinny side. If you get something sticky on it? Dampen your cloth with a little distilled water, and wipe as I mentioned above. Wait until your CD rom is completely DRY before inserting it to try to use it again.

What is the CD rom? What is a CD rom used for? The CD rom is used for storage basically, and most programs now days are CD roms. There are different types of CD roms as well, and we will go over that in another lesson.

Where is CD Drive?

In previous lessons I was trying to explain the different types of disk drives. The last type of disk drive is called the CD Drive that you place CD Roms in. Let me show you a picture of the drive with a CD Rom in it.
CD Rom Drive or D Drive

For my computer the E drive is my CD rom drive. How did I figure that out?

My Computer Icon
You can either go to 'my computer' on your desktop, OR

Vista has renamed "My computer" to just 'Computer'.

Most of the time Windows Vista and XP don't have their version of 'my computer' on the desktop. If you have it on your desktop it could look similar to this:

Vista My Computer Icon

If you see 'my computer' or 'computer' like pictured above on your desktop double click it at this point.


If you don't have one of those icons above (or similar) Hit your start button, and then go to computer (newer systems like Vista) or 'my computer' for other versions of windows. You should see a bunch of disk drives with letters. We are only concerned with those at this point. We will go over the other items you see later (if you have any).

'my computer' screen shot for XP

Keep in mind your 'my computer' or 'computer' screen may be a little different then pictured, but the principle is the same.

You may see pictures of drives and letters. C Drive is normally your Hard Disk Drive. In some of the newer systems you will actually SEE a picture of a CD rom like above, and at times your drives will be named for you (windows, floppy, CDrom, DVD, etc). My CD rom drive says, "DVD RW DRIVE". At times some computers DON'T make it that easy for you to identify things! That will be in a future lesson about device manager.

We will look at the device manager in a future lesson, and you will see how your computer identifies your CD Rom among other things! Where is the CD Drive? For now check under your 'my computer' or 'computer' section on your computer.

What is an Operating System?

What is an Operating System? The operating system of your computer is the is the MOST important program, and basically the backbone of your computer. We deal with Windows PC's on this blog, and your operating system can be called:

Windows Vista
Windows XP
Windows 2000
Windows ME
Windows 98
Windows 95

Those are some of the names that seem to be the most popular for operating systems software for your computer.

If you are reading about operating systems you may see people call them OS or O/S. Those are short abreviations for the word 'operating system'.

The purpose of an operating system is to organize and control hardware and software so that the device it lives in behaves in a flexible but predictable way.

Believe it or not operating systems have started to pop up in smaller computers as well. If you tinker with electronic devices, you're probably thrilled to know that operating systems can now be found on many of the devices we use every day, from cell phones to video games. The computers used in these devices have gotten so powerful that they can now actually run an operating system and applications. The computer in a typical cell phone is now more powerful than a desktop computer from 20 years ago. Hard to believe isn't it?

What is an operating system? You see it as Windows Vista, or one of the others titles I mentioned above. What does an operating system do? It provides basic instructions your computer needs to function.
