Air Sealing Is the Simplest and Most Efficient Way to Save on Your Energy BillWe’ve looked at several ways to save on your energy bill, but among them all nothing does the job better than air sealing. Utility bill comparison site MyEnergy explains:

The EPA estimates that between 25 and 30 percent of the energy that we use to heat and cool our homes is lost due to the air leaks through the attic, the basement, and other gaps in the building envelope. The absolute largest return on investment when it comes to energy savings is quick air sealing using caulk or spray foam. Spray foam or foam-in-a-can has been proven to save up to $150 per year in heating/cooling costs, and to have a seven year ROI (return on investment) of 4400%. The living space is the easiest to airseal yourself, however attics and basements can sometimes require a contractor depending on the scope on the project.

If you want to seal the gaps in your home, this EnergyStar guide is a good place to start. GreenVideoAdvisor offers a series on sealing your attic and Building Science provides another.

Special thanks to MyEnergy for the tips!

Cellphone Dock Ignition Lock Keeps Your Kid from Texting and Driving and Wrapping the Family Car Around a Tree

By Andrew Liszewski, GizmodoMarch 18, 2013 at 09:06AM

If you absolutely can’t trust your kid to avoid texting while he’s driving the family car, the ORIGOsafe provides a brute-force way to keep them focused on the road. It’s a smartphone dock that prevents a vehicle from actually starting until a phone is inserted, ensuring the distraction remains out of sight. More »

Jettison Automatically Ejects External Drives When Your Mac Goes To Sleep

By Shep McAllister, LifehackerMarch 17, 2013 at 02:00PM

Jettison Automatically Ejects External Drives When Your Mac Goes To Sleep OS X: Jettison is a handy Mac utility that runs in the background and automatically unmounts external drives when you put your computer to sleep.

While it’s usually okay to yank out USB drives without ejecting them, you probably shouldn’t get in the habit. OS X still uses write caching on external drives when the system is asleep, so you run the risk of corrupting data if you close your MacBook and pull out an SD card or external hard drive. With Jettison enabled, your computer will force eject all of your drives immediately upon sleeping, and will even remount them automatically when you return.

I constantly forget to unplug everything before closing my computer, so Jettison saves me the trouble of waking the machine up, keying in my login password, and ejecting the drives manually. If you have the same problem, Jettison can solve it for $1.99.

Combine IFTTT and Pocket, Evernote, or Gmail for a DIY Google Reader Replacement

By Alan Henry, LifehackerMarch 15, 2013 at 07:30AM

Combine IFTTT and Pocket, Evernote, or Gmail for a DIY Google Reader Replacement We’re all bummed that Google Reader is going away, and while we’ve highlighted some alternatives (and are looking for your favorites, too!) you may not even an alternative when IFTTT and any bookmarking service of your choice (in this case, Pocket) can give you similar results.

Over at The Lab, Ruth explains that even though Google Reader is gone, you can use IFTTT and Pocket (or any similar article-saving service of your choice—you could just as easily use Evernote, Dropbox, even Gmail to house your articles) to get new articles from your favorite blogs dumped into a central location where you can read and organize them whenever you want. She specifically suggests “read it later” type services because they’re designed for article reading and organization, so while her recipe uses Pocket, you can use it as-is or sub in Instapaper or Readability if you prefer.

We could see the same recipe modified to send articles from your favorite sites to Gmail, and then a Gmail filter to take new articles that land in your inbox to be directed to a specific Gmail filter—maybe called “Reader”—to duplicate the Google Reader experience. It might be overkill if you have hundreds of feeds, but if you were only using Google Reader for a few blogs here and there, it might be worth a look. Hit the link below to read more on how Ruth did it, and to grab her recipe.

Have a Hard Time Tracking Debts With Friends? Use What Do I Owe You

By Joel Lee, MakeUseOfMarch 14, 2013 at 10:01PM

Like most people, I enjoy going out to places with my friends. Restaurants, movies, overnight trips, amusement parks, paintballing – you name it and I’ll go. Going out as a group is great but sometimes there are complications, especially when it comes down to money.

Don’t get me wrong, I’ll cover someone if they’re short on cash and I’ve been covered on occasion as well. However, if your group of friends (or family, coworkers, colleagues, etc.) is the type that expects everyone to be reimbursed perfectly, the whole act of tracking debts can become a headache. This is also applicable to roommate situations where different people are paying for different bills.

Fortunately, there’s a new website that aims to solve this problem. It’s called What Do I Owe You? and it’s an extremely simple solution that gets the job done – and it’s different from traditional bill splitters and budget managers.

Here’s the basic layout of the website. Don’t be turned away by its simplicity, though. Haven’t you ever heard not to judge a book by its cover?

The gist of What Do I Owe You? is that you can add or remove people from the group that you want to split bills with. Each person has a name (which is by default “Click to Edit“)  and a list of items that they’ve paid for. As far as I know, you can add as many items per person as you want.

When you’re done with all of the items for all of the people, a single “Who Owes What?” click will tell you what each person owes to whomever else.

Editing people in the group is easy, too. To change their names, all you have to do is click on the “Click to Edit” and start typing.

The “Add Bill” button will add more input fields where you can more items that they’ve paid for. The text field is smart because you can start it off with a money value (like $40.00) and the rest of it will be ignored, so you can use that to describe what that bill was for.

Here’s an example setup that I’ve created. As you can see, it’s as straightforward as can be. As far as I know, there are no limits to how many people can be added to the group. (I stopped at 25 because there will never be a situation where I need to track 25 casual debts with my friends.)

And finally, once you click that beautiful “Who Owes What?” button, the site will tell you what each person owes and to whom they owe that amount. Again, it’s not very pretty and there aren’t too many bells or whistles that go along with it, but the information is accurate.

If you want to start over, there’s a Reset option. You can also send an IOU Email to an address, which presumably reminds them in a friendly way that they have a debt to settle. Perfect for people who don’t like face-to-face confrontations!

The last two features are what make What Do I Owe You? something that will be used by many people – mobile support and progress saving.

At the bottom of the site, there’s a link that lets you switch into a mobile version of the site. On some devices, the site may detect that you’re on a mobile phone and change its format accordingly. Either way, I’m sure there are many applications for this website while on the go, so having mobile support is aces.

Progress saving is also quite nice. If you want to do long-term tracking of debts, just update the bills and click “Save” at the top right. This will tie your progress with your browser using a cookie and all of your data will be reloaded whenever you come back. However, in case you delete your cookies mistakenly, the site provides a link that you can use to restore your progress.

Overall, a fantastic website. The graphics could use some polish (okay, a LOT of polish) but the functionality is great. If more people used the site, I’m sure the creator would keep it updated with new features over time. There’s a “Feedback” link in case you want to send in your comments and suggestions.

Puzzle box: The quest to crack the world’s most mysterious malware warhead

By Dan Goodin, Ars Technica » Risk AssessmentMarch 14, 2013 at 09:00AM

It was straight out of your favorite spy novel. The US and Israel felt threatened by Iran’s totalitarian-esque government and its budding nuclear program. If this initiative wasn’t stopped, there was no telling how far the growing conflict could escalate. So militaries from the two countries reportedly turned to one of the most novel weapons of the 21st century: malware. The result was Stuxnet, a powerful computer worm designed to sabotage uranium enrichment operations.

When Stuxnet was found infecting hundreds of thousands of computers worldwide, it was only a matter of time until researchers unraveled its complex code to determine its true intent. Today, analysts are up against a similar challenge. But they’re finding considerably less success taking apart the Stuxnet cousin known as Gauss. A novel scheme encrypting one of its main engines has so far defied attempts to crack it, generating intrigue and raising speculation that it may deliver a warhead that’s more destructive than anything the world has seen before.

Gauss generated headlines almost immediately after its discovery was documented last year by researchers from Russia-based antivirus provider Kaspersky Lab. State-of-the-art coding techniques that surreptitiously extracted sensitive data from thousands of Middle Eastern computers were worthy of a James Bond or Mission Impossible movie. Adding to the intrigue, code signatures showed Gauss was spawned from the same developers responsible for Stuxnet, the powerful computer worm reportedly unleashed by the US and Israeli governments to disrupt Iran’s nuclear program. Gauss also had links to the highly advanced Flame and Duqu espionage trojans.
