If you're setting up a worksheet only for yourself, you can simply leave an empty cell for this purpose. To check it, just type in an x or any other character. Then use a formula with the =isblank() function to make the contents of that cell affect the rest of the spreadsheet. But you might want something more mouse-friendly--especially if you're designing a spreadsheet for other people. I've tested the technique below on Excel 2007, 2010, and 2013. I'm not sure about earlier versions. You can insert checkboxes on Excel's Developer tab. Unfortunately, that tab is hidden by default. To make it visible in Excel 2010 or 2013, click the File tab and select Options. ClickCustomize Ribbon. You'll see two lists. Make sure that the one on the right is titled Main Tabs. Check Developer.

Windows Updates, as you know is a legitimate software update from Microsoft to make the operating system stable and secure for improved performance. By default the feature remains enabled, however, you have the option to configure it further. Set Windows to automatically install updates or get your permission prior to it. Generally, after Windows Update the system automatically shuts down due to the replacement of the Shut Down option in the Start menu with the "Install Updates and Shut Down" button. This phenomenon is sometime irritating.

An excellent set of programming challenges.

Since it never hurts to learn something new, especially a skill set like computer programming in different languages, we will go over some of the best channels that will introduce you to the world of programming. Let's look at which channels made the cut.

We're one step closer to the Robocalypse: a research team at Japan's Kagawa University has developed a robot that's able to "speak" like a human being. While talking robots are not new by any means, this model isn't using software but a set of mechanical, human-like vocal organs, for example artificial vocal chords or a tongue and lips that are made of silicone

File syncing is a godsend when you work on multiple computers or devices and want to make sure you have the most up-to-date files wherever you log in. While online services like Dropbox may be the most convenient options, there are plenty of reasons you may want to "roll your own cloud" and sync your files to your own web server or just on your local network. 

"Topics include abstraction, algorithms, encapsulation, data structures, databases, memory management, security, software development, virtualization, and websites. Languages include C, PHP, and JavaScript plus SQL, CSS, and HTML. Problem sets inspired by real-world domains of biology, cryptography, finance, forensics, and gaming. Designed for concentrators and non-concentrators alike, with or without prior programming experience."

This article about Pair Programming is an excellent description of the process and how it can improve productivity. The company, Xtreme Labs, has set work hours and they are still very productive. Xtreme Labs is a mobile app developer primarily from Toronto that is growing extremely quickly.

Why it's a good idea to own a USB-to-SATA adapter The USB-to-IDE/SATA adapter the most indispensable tool in my PC repair kit. Just this weekend, it once again proved itself worthy of that title. In a nutshell, the adapter allows you to connect an internal hard drive to your PC-externally. What would an internal drive be doing outside your desktop or laptop? Funny you should ask. About a week ago, my media-center PC starting displaying this message during boot-up: "Hard drive failure imminent." And you know what? It was. In short order, the machine wouldn't boot at all. Long story short, I had to replace the drive, reinstall Windows, etc. But I wondered if I could salvage any/all of my recorded TV shows. To find out, I connected the old, non-booting drive (now "naked" outside the system) to a USB port via my adapter. Huzzah! The machine was able to read the drive and copy over the recordings. Except for the hassles (and expense) of actually replacing the drive, no harm done. There's another reason to keep one of these adapters on hand, and that's if you're planning to upgrade to a solid-state drive (SSD). Unless you buy a kit that comes with an adapter, you'll need one so you can image (i.e. clone) your existing drive to the new SSD. Then you'll remove the old drive, install the new one, and presto, you're back in business. (Much faster business: SSDs rock.) Unless you have a pretty old desktop or laptop, you can skip buying a USB-to-IDE/SATA adapter and just go for USB-to-SATA. At the same time, I recommend one that supports USB 3.0. You may not need it now, but it's a good bet your next PC will have USB 3.0 ports -- and that'll make for much faster copying between drives. Trust me: When the time comes that you need to upgrade or replace a hard drive, you'll be glad to have a USB-to-SATA adapter on hand. By-The Xpert Crew @ http://techvedic.com

There's nothing you can do if hackers get into a database with your password in it, but you can still protect yourself for all the other worst-case scenarios involving hacking. First, don't make it easy on hackers by choosing a common password. Splashdata uses security breaches to gather 'most popular passwords' lists each year. The word 'password', number sequences, and other simplistic phrases or numbers fill the top spots. Also, don't use your name, a password related to another one you might have on a different site, or a login name. Instead, experts recommend using 15 characters, upper-case letters, better yet nonsensical words with special characters and numbers inside them. By-The Xpert Crew @ http://techvedic.com

"It might just be the precursor to the next industrial revolution and slowly but surely, 3D printing is expanding its presence into the realm of manufacturing. Now it seems that one of the first major industries to benefit from 3D printing is the same one that spawned the assembly line revolution - the automotive industry. Israeli company Stratasys, already a major player in the field and its subsidiary, RedEye On Demand, will be part of a project aimed at putting the first 3D printed car on the roads within two years, in partnership with KOR EcoLogic. "A future where 3D printers build cars may not be far off after all. There is a vision for a more fuel-efficient car that would change the world . URBEE 2, the name of the car, shows the manufacturing world that anything really is possible. There are few design challenges [3D printing] capabilities can't solve.""
