Microsoft Open Technologies has recently launched a service called VM Depot that allows you to quickly and easily scan for virtual machines. Correcting for one of the original pitfalls of Azure, the inability to quickly find a list of virtual machines, this new service puts this list at your finger tips – and Linux stands out!
Ah, the holidays. For me, the holidays are about getting stuff: getting fat, getting happy and getting lots of good pictures of your adorable nieces and nephews to embarrass them with when they become teenagers. But now that you’re on Ubuntu, what program should you use to manage the
evidence pictures? Well, here is my review of some of the more popular (and free!) offerings available to Ubuntu users.
On some distributions, MySQL is installed without asking you to set the default root password for the MySQL server. If you’re running Debian or Ubuntu, the MySQL install will prompt you to create your password. However, some distributions such as CentOS aren’t as friendly. When MySQL is first installed on CentOS, it finishes without any user interaction. In fact, it finishes without a set root password, without starting the MySQL service, and without configuring the MySQL service to start on system reboot/boot.
Until recently, the most viable cloud option for Linux virtual servers has been Amazon Web Services. But in mid 2012, Microsoft launched Linux Virtual Servers on Windows Azure. If you don’t know already, Windows Azure is a cloud platform for hosting back-end content for apps and traditional Windows Server, SQL Server, and now Linux and other open source database servers. Microsoft has come a long way with its support for open source and Linux. Given that, I set out on a mission to review and compare these services to Amazon. I’ll be honest up-front–when I set out on this mission I was completely biased towards Amazon, and I was surprised by what I found.
For SpaceX, 2012 was the year of the Dragon. In 2013 the Falcon Heavy, SpaceX’s heavy lift vehicle, is set to steal some of the spotlight away from the Dragon.
The Falcon Heavy is currently in development and builds off of the Falcon 9 first stage and the Merlin 1D engine, an upgrade of the engine currently flying on the Falcon 9. What makes the Falcon 9 design so reliable is the ability to handle several engine failures without having to abort or experience a R.U.D. (SpaceX lingo for an explosion, a.k.a. Rapid Unscheduled Disassembly). Along with the engine reliability the Falcon Heavy will be the first rocket in history to feature propellant cross-feed from the side boosters. Since the rocket does not need full throttle to maintain acceleration as it travels into the atmosphere, the center core reduces throttle as the rocket ascends with the side cores still at full throttle. This allows for the core stage to be close to full of propellant when the side boosters separate, essentially leaving a fully fueled Falcon 9 ready for liftoff many miles above the earth. (more…)
