How do you choose the best Linux filesystem for your MariaDB server? The primary factors to look at are data integrity, performance, and ease of administration. Data integrity tops the list because fixing a corrupted database is even less fun than it sounds, and filesystems play a key role in data integrity. Performance is important because faster is better and time is money, and ease of administration matters for the same reasons as performance.

The command “tee” it’s one of the basic commands that you should find in any system, yet it’s not so popular or use, this command reads standard input and writes it to both standard output and one or more files, effectively duplicating its input. It is primarily used in conjunction with pipes and filters. The command is named after the T-splitter used in plumbing. In short if you want to redirect the STDOUT of any command as well as printing it to the screen, tee is the right tool to use, let’s see some practical use of this command.
Portable apps aren't anything new. There are variations of "single executable apps" for most platforms, and some people swear by keeping their own applications with them for use when away from home. I don't usually do that, as most of what I do is on-line, but there is one exception: security. When I'm asked to help a Windows user figure out what is wrong with his or her computer, I generally take a USB drive and nothing else. I also usually run dd on that Flash drive when I get back home, because Windows can be a breeding ground for nasty infections.
Public cloud computing and Big Data analytics have converged in a new partnership between MemSQL and GoGrid designed to simplify the orchestration of MemSQL's in-memory distributed database system for business intelligence. MemSQL and GoGrid are both invested in high-performance Big Data computing. MemSQL's platform leverages in-memory storage to speed both real-time and historical data analytics, while GoGrid tailors to customers interested in Big Data-oriented hosting solutions that include SSD storage, large amounts of RAM memory and dedicated servers.
The idea of creating a Linux distribution with Firebird database came to me a long time ago when I was structuring the IT department of a company which develops automation software for drugstores.read more
Tesla's decision to open source its patents has piqued the interest of a few of the world's larger car manufacturers. According to the Financial Times, Nissan and BMW are allegedly "keen" to chat with Tesla about possibly working together to develop charging networks that all three manufacturers' vehicles could use. Musk's announcement was a bit of a surprise, with some seeing it as helpful suggestion by the company for pushing the growth of the electric vehicle market to new heights. Others chastised Tesla's announcement, commenting that it was a sign of the company's weakness and a desperate bid to move an industry that, by large, is fairly gasoline-focused. Without such a shift, critics argued, Tesla might not have enough individual oomph to make it in the difficult car market.
Building an active community requires thoughtful planning, patience, support, and constant evangelism. Even then, any of several well-known errors can prevent a community from developing.
How to Add a Swap File On Ubuntu LinuxA swap file enables an operating system (OS) to utilize hard disk space to simulate additional memory. Effectively, as the system goes on the low-memory mode, it swaps a certain section of the RAM that an idle program may be using onto the hard disk to release memory capacity for other vital programs. Subsequently, when the user returns to the swapped out program, it swaps places with another program in RAM. This intelligent mix of RAM and swap files is commonly referred to as virtual memory, and its use allows the system to run a far greater number of programs than possible using only the built-in RAM.
Recent developments in the world of open source have had far reaching impacts more so than most critics initially envisaged. For example the recent announcement that the National Aeronautics and Space Administration (NASA) is committed "... to the principles of open government" and "... (to) encouraging innovation and entrepreneurship," and thus will be releasing source code for an array of its software projects, hits home to the authors of this article.read more
"If your phone can be connected to your computer with an USB cable you can do a lot more through this connection than just recharging it or transferring files to and from your phone's storage. For example, you can make phone calls, read and send text messages, and see a bunch of other information from your phone, right on your PC. There is a number of Free Open Source software applications that allow you to do this, and you don't even need to have a smartphone for this to work, just a phone that can connect to USB."
The medical image community embraced open source as a standard practice back in 2000, with the adoption of the Insight Toolkit (ITK). ITK is sponsored by the US National Library of Medicine and was built as a C++ library. It is the equivalent to a usable encyclopedia of image processing algorithms.read more
