The vast majority of vehicles are powered by what's known as an internal combustion engine.
It's a concept that's been around for a long time but a Belgian engineer, called Jean Joseph Etienne Lenoir, is credited with inventing and patenting the first viable internal combustion engine in 1860.
The internal combustion engine isn't as complicated as it might sound. As the name suggests, it burns a mixture of fuel and oxygen in an enclosed space called a combustion chamber.
As this mixture burns it becomes hot and expands rapidly, creating pressure. This pressure is applied to … Read more
A relatively long-standing issue exists in OS X that could, given the oversight on toggling certain system settings, result in the inability to access your Mac if you use multiple input methods.
One of the security features in OS X is to require a password when waking the system or deactivating the screensaver. This feature, set in the Security system preferences, can be timed such that it activates immediately or after a delay of up to 4 hours once the screensaver or Sleep mode is activated. As with the log-in screen, this will require you supply your account's credentials … Read more
There are so many photo editors out there for your iPhone that it's hard to keep up--and we've tested a lot of them. There are many that proved to be powerful tools for customizing your iPhone pics; however, there are just as many that have failed to impress us. Sadly, Pro Photo Layout is yet another photo editor that falls in the latter category.
We realize that many free apps come with strings attached in the form of ads, but while some publishers are able to design around ads so that they are unobtrusive, others don't and … Read more
Google on Wednesday made a big announcement regarding Gmail's overall look and feel. Gmail will be taking a new tabbed approach to helping users organize e-mail -- something I'm sure we all struggle with. Over the next few weeks a new tab workflow will be slowly introduced to the Web, iOS, and Android versions of Gmail.
While iOS and Android users have to wait for app updates to hit the respective stores to get the new Gmail, there's a chance your Gmail account on the Web already has access to the feature. It's a quick process … Read more
For those looking to change Facebook's layout, Facebook Layouts for Mac adds some flexibility to the social network's design, but it didn't always work as promised and ultimately has few options that would appeal to adult users.
The application's Web site claims it is compatible with the major Web browsers. When downloading the free add-on, the file format was only readable by Firefox and would not work in other browsers, like Safari, which is a disappointment. Once in Firefox, Facebook Layouts for Mac did install properly and worked after a restart of the browser. The add-on … Read more
Circuit and electronics designers may need an option to better design products on a Mac. LayoutEditor for Mac may not be worthwhile for the average user, but for those needing this type of software, it could be a good option.
Download and installation of LayoutEditor for Mac occurred quickly despite the lack of a native installer. After startup and the acceptance of a lengthy user agreement, the program starts quickly, but lacks any instructions or visible support. The interface is confusing to the average user and the Help section did little to demonstrate the program's features. There are several … Read more

yEd Graph Editor has an attractive interface, with a tabbed work area that lets you have multiple files open at once. Several aspects of the … Read more
Well, I'm bummed. I paid $75 for this product just a few months ago. But I needed it at the time, and it was worth it.
That makes this deal all the more un-pass-up-able.
Today only, PricePlunge has Serif PagePlus X5 for $14.99, plus $1.99 for shipping. Yep, it's an actual boxed copy, not a download. How quaint!
Update: Sold out! Rats. That went really fast. The closest I can find elsewhere is $42.99 shipped at Amazon. Viewed in a vacuum, that's still a great deal. (But not as great as $15, I admit.)… Read more
