Virtual Hosting With vsftpd And MySQL On Debian Squeeze
Vsftpd is one of the most secure and fastest FTP servers for Linux. Usually vsftpd is configured to work with system users. This document describes how to install a vsftpd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine.
The Raspberry Pi is still picking up momentum with different types of DIY projects. If you’re looking for a means to build an old-school computer-in-a-keyboard with a Raspberry Pi, the German blog Preamp shows you exactly how to do it. More »
Rob Clark, the Texas Instruments developer known for his work on the OMAP DRM driver, DMA-BUF, and hacking a Qualcomm open-source driver in his spare time, has been dabbling with Wayland. Rob’s done some optimizations and simplifications to shaders used by Wayland’s Weston reference compositor that greatly improve the performance…
As expected, with Marek Olšák requesting a delay in branching Mesa 9.0 so that he can land more features, support for multi-sample anti-aliasing (MSAA) for more ATI/AMD Radeon hardware has landed plus there’s improved anti-aliasing support for currently-supported GPUs…
Support for OpenVMS is set to be removed from Mesa due to lack of maintainership in four years and trimming out the OpenVMS can shave just over two thousand lines of code…
When life gives you lemons, everyone knows you should make lemonade, as the old saying goes. But what if life gives you Linux on a Retina MacBook Pro? That, too, has been shockingly referred to as a “lemon” in recent days, but the solution there isn’t so clear. “If you are planning to buy one of the new Apple MacBook Pro notebooks with a Retina Display for use under Linux, hold off on your purchase,” warned Phoronix’s Michael Larabel in a review last week. “Running the Retina MacBook Pro with Linux isn’t a trouble-free experience.”
In this video, John Lockwood from Algo-Logic presents: A Low-Latency Library in FPGA Hardware for High-Frequency Trading (HFT). Recorded at the Hot Interconnects 2012 conference in Santa Clara.
Current High-Frequency Trading (HFT) platforms are typically implemented in software on computers with high-performance network adapters. The high and unpredictable latency of these systems has led the trading world to explore alternative “hybrid†architectures with hardware acceleration. In this paper, we describe how FPGAs are being used in electronic trading to approach the goal of zero latency. We present an FPGA IP library which implements networking, I/O, memory interfaces and financial protocol parsers. The library provides pre-built infrastructure which accelerates the development and verification of new financial applications. We have developed an example financial application using the IP library on a custom 1U FPGA appliance. The application sustains 10Gb/s Ethernet line rate with a fixed end-to-end latency of 1μ – up to two orders of magnitude lower than comparable software implementations.â€
You wouldn’t think supporters of open source would be collectively discussing Disney’s latest episode of “Shake It Up,” but there’s a first time for everything. Earlier this week, the children’s TV show misrepresented the meaning of open source, reminding us that in film and TV script writers often generalize programs, platforms and ideas in technology to the point of skewing the definition of them completely.
Sony has moved its open source DASH framework to Github for better collaboration; the hardware abstraction layer for sensors should help Android ROM makers to quickly enable more sensor hardware, especially on Sony phones.
