A New Competitor to the Apple Watch: The Pebble Smartwatch


We wanted to make sure that we built a system that works," says Migicovsky. Because Pebble isn’t as deeply integrated into your phone’s system as the Apple Watch or Android Wear, doing anything more would be difficult.) For similar reasons, Pebble Time eschews the more complicated heart rate monitoring and other health tracking systems Android Wear and the Apple Watch support and sticks with a basic motion detector to count your steps.

CIOs Are Discovering That Containers Might Be The Right Way To Ship Code

The Accidental Successful CIO

In order for the software to operate correctly, the supporting software in the environment has to be identical to the software that was present when the software was developed. With virtualization technology, the package that can be passed around is a virtual machine and it includes an entire operating system as well as the application. By contrast each container shares the operating system kernel with the other containers.

IO Improvement: Making Your Computer Perform Better Than New

Strategy Driven

In simple terms, this is the process of making your system components run at higher speeds than they would out of the box. This is usually achieved through the BIOS before you get to Windows, OSX, or Linux, and will involve raising voltages and clock speeds until you have a stable, but much faster, system in place. There are loads of guides around the web which can be used to make this easier, and you should always aim to find ones which cover your exact hardware.

The bad news is that because the vulnerabilities are in the hardware architecture of the chips that power them, patched devices may run slower. Meltdown breaks down the barriers between software and the operating system; Spectre breaks down barriers between software programs. Meltdown lets malicious software access the memory of other software, and the operating system; Spectre “tricks” an otherwise-safe program into leaking sensitive data.
