In this post, I'll answer a question to which I hoped I'd find an answer on the internet--but I did not manage to find that answer. The question is about minimal specs for a motion-capture machine and, though my answer will have to remain somewhat imprecise owing to the fact that I did not test multiple systems, it will at least give a probable base-line for what may be the lowest-powered system one could use for the task I'm describing.

The Network Time Protocol is one of the oldest protocols in the TCP/IP Protocol Suite. The protocol was designed in 1985 by David L. Mills of the University of Delaware. As of June 2010, NTP has a current version of 4, sometimes referred to as NTPv4.

This wasn’t the case with a group of Reddit users last week, where a scene broke out in a comment thread that pretty much turned into a mob that reminded me of the Cooks Source massacre of 2010. It seems that a few folks don’t need to know the full story before picking up their virtual weapons and launching an attack. They’re ready to bring SourceForge to its knees by flooding all of SourceForge’s download mirror sites with emails vilifying the service.

Angel 2.5 is now available. Angel Linux is a newer Puppy-based lightweight desktop oriented Linux distribution.

Many computer users are familiar with the basic idea of filesystems. A storage device is divided into partitions each formatted to a particular filesystem that holds files. Well, just as the filesystem hold the files, a partition table holds the filesystems. There are a few partition table types. The most commonly known one is MBR.

Sony has just launched its PlayStation 4 console, and it seems that the rumours about being based on FreeBSD are actually true.

You flashed an SD card with Raspberry Pi image, and plug the SD card into Raspberry Pi. Then what next? The first thing to do after booting Raspberry Pi is to configure your Raspberry Pi. Each Raspberry Pi system comes with its own software configuration tool. For example, use raspi-config for Raspbian, firstboot for Pidora, etc. This tutorial explains how to perform initial configurations on Raspbian-powered Raspberry Pi by using raspi-config tool.

Many Linux users know at least some shell scripting due to its importance. However, many users are not aware of the importance of Python scripting in Linux. True, shell scripting is more important than Python scripting, but Python is a very useful scripting tool in Linux. This is a general tutorial for Python3.

Run apps directly on the Glass hardware Google has unveiled what it's calling a "sneak peek" at its Glass Developer Kit (GDK), a new way to write software for the Chocolate Factory's privacy-stomping future-specs.…

What options are available for users who want a file and application launcher similar to the one found in Ubuntu's Unity desktop, but under a different desktop environment or distribution? That’s what I set to find out.

In 2002, the GSyC/LibreSoft research group at the Universidad Rey Juan Carlos successfully surveyed a broad swath of over 2500 respondents (mostly developers) from open source and free software communities. They have long been researching and collaborating with Free and Libre Open Sourse Software (FLOSS or FOSS) organizations and groups and are back again to recreate the survey with the goal of assessing where the community stands today after over ten years of evolution and innovation. This year, the Libresoft research group encourages anyone involved in a FLOSS project (not only developers) to participate in the survey.

How to install Nagios 4.0.1 (Monitoring Tool) in ubuntu 13.10 server (Saucy Salamander)

I love distros that try and mimic other OSes. They lessen the blow of using a new OS and encourage inexperienced users to take the plunge into Linux. In that respect, Pear OS 8 is a wonderful imitation of Mac OS X, but does a poor job of presenting the best of Linux.

Today in Open Source: The NSA wanted a backdoor into Linux. Plus: openSUSE 13.1 review, and Mir won't be in Ubuntu 14.04

Google's faster-than-expected upgrade of all its SSL certificates to an RSA key length of 2048 bits will make cracking connections to the company's services more difficult without affecting performance, experts say.

One of the best emails to get before a conference you're psyched to attend is the one that outlines all the final details. It links to the final speakers' schedule, reminds you of important things like where to park and when to check-in, and of course, that email tells you about the fun parties. That email revs you up and organizes you for the conference to come. So when I opened up the "final details" email for the recent All Things Open conference in Raleigh, I was expecting to see an outline of the typical who, what, when, where info. I wasn’t expecting the first item to be a reminder of the conference's anti/no harassment policy. But there it was—the first item on the list:

This is a condensed version of the blog post: Hey Civic Hackers! How about leaving the ninja skills at home and building really useful applications? It includes more analogies and cars. Comments welcome. Most hackers are deeply involved in the tech scene. They keep up to date with the latest technologies and will use tech that is in the early phases of adoption. They have no problem using cloud services, NoSQL data stores, languages with smaller communities, and target more recent browsers or phones. They don't mind doing custom configurations on server software, they probably already know some of the maintainers of the project and can get special help, and they know other hackers who they can reach out to. They generally come from a startup world or at least from software companies where budgets and skill sets are generally high for employees.

Recon Instruments announced an Android-based $399 heads-up display (HUD) designed to fit inside ski goggles. The Snow2 is equipped with a 1GHz, dual-core processor, a 428 x 240 mini-display, plus WiFi, Bluetooth, GPS, and sensors, and it syncs to Android and iOS devices. The Snow2 updates a previous MOD Live HUD wearable that was similarly […]

This tutorial shows how you can install and run ownCloud 5.0 on a Debian Wheezy system that has nginx installed instead of Apache (LEMP = Linux + nginx (pronounced "engine x") + MySQL + PHP). nginx is a HTTP server that uses much less resources than Apache and delivers pages a lot of faster, especially static files.

Olimex’s OLinuXino project announced a tiny, Android- and Linux-ready single board computer based on Allwinner’s 1GHz, Cortex-A8 based A10 processor, and the first one to be offered with a mini-PC enclosure. The open source A10-OLinuXino-Lime offers 512MB of DDR3 RAM, an optional 4GB of NAND flash, plus HDMI, SATA, USB, and Ethernet, starting at only […]
