How to setup Single Sign On with OTP using simpleSAMLphp and privacyIDEA This howto will deal with Single Sign On to web pages. Maybe you know OpenID. Similar to Kerberos a "Ticket" is granted to the user to authenticate at other services using the ticket and not the credentials anymore. In this howto we will use SAML (Security Assertion Markup Language) which is more sophisticated than the simple OpenID. SAML can be used to setup trust relations between several entities. This is why it is used between companies and organizations, why online service are using it.

Have you ever wanted to move between rooms while watching or listening to the same film or song? We often find ourselves switching from a phone or tablet to the desktop. There are some complicated setups you can use for this involving MythTV and various custom- built servers and receivers, but you can also do it with just one Raspberry Pi server and then many XBMC receivers with a lot less hassle.

Using the Raspberry Pi for around the past two years has generally been pretty fantastic. It took us a year or so to stop being surprised by just how much it was able to do in the various projects we saw or made ourselves. One thing that we always struggled with was web browsing though; Midori was slow and laggy and it would take up all the Raspberry Pi’s system resources as well.

Women in open source are making revolutionary contributions and paving the way for others as they innovate in the field. In tandem with the Grace Hopper conference happening this week, I put together a healthy dose of knowledge on the subject with a quick spotlight on five talented women in open source. A few of them give advice on working in tech.

Firefox OS is now available on three continents with 12 smartphones offered by 13 operators in 24 countries. As the only truly open mobile operating system, Firefox OS demonstrates the versatility of the Web as a platform, free of the limits and restrictions associated with proprietary mobile operating systems.

Google has removed a free educational app, dubbed AndroidScript, from its Play store, for breaching the ad giant's terms and conditions. According to the app's developer, Dave Smart, Mountain View abruptly yanked AndroidScript from its online shop without notifying him of the decision in advance.

A “Pi Vessel” mini-PC on Kickstarter is based on a Raspberry Pi Model B or B+, and has an “ultra-strong aluminum case,” AC power supply, and optional WiFi. The Pi Vessel is said to be made in Germany, but is available from a Dover, Delaware based startup called MSDGroup, one of many companies of the same name, but apparently not one that has a website. The Pi Vessel is available on Kickstarter through Nov. 5 starting at $89 without a Pi or $129 with either a Raspberry Pi Model B or the newer RPi Model B+.

Pactron announced a Linux-based “Sherwood” COM Express Module and hardware development kit built around Marvell’s Armada XP SoC featuring four ARMv7 cores. Silicon Valley based contract manufacturer and ODM specialist Pactron is debuting on LinuxGizmos with a COM Express Type 5 module based on a system-on-chip that’s been around for awhile. The Armada XP is several years old, but was only fully documented by Marvell this July. The Sherwood COM Express Module uses the quad-core version of the SoC, which has ARMv7 cores somewhat similar to a Cortex-A9 design. Other modules based on the Armada XP include Cogent Computer’s SODIMM-style CSB1726, which is also available with the dual-core version.

When security researchers Adam Caudill and Brandon Wilson publicly released attack code two weeks ago that takes advantage of an insidious vulnerability in USB devices, they argued that publishing their exploits would get the problems fixed faster. Now they've released a partial fix themselves-albeit one that's so messy it includes coating your USB thumb drive in epoxy.

This year's keynote speaker at the annual All Things Open conference is Red Hat's DeLisa Alexander, executive VP and head of Red Hat's human resources operations. DeLisa is not only in a professional position to comment on gender and diversity in open source and tech but has also personally campaigned for inclusiveness in the workplace to produce better outcomes for everybody.

How do you find the right open source project to jump into? Here's a guide based on my jouney to find the right fit. In the guide, I wrote about doing your research by casting a wide net, then evaluating yourself (your skills, your goals, and your time). In this evaluation to find the right fit, I looked at my motivations and skills, made a list of goals, and named a few target projects. Because this isn’t my first rodeo, I take a good, hard look at my track record. What can I learn from the ones that didn't stick to find the one that will? I notice patterns I can avoid and see how they line up against my new list of goals and skills. Then, I evaluate four open source projects and their communities to see if they might be a good fit. See the winner at the end!

Barely two months after the Linux 3.16 kernel release and Linux 3.17 is now out. The Linux 3.17 kernel is the fifth major kernel release so far in 2014 and among its features is a fix for a flaw that wouldn't actually impact Linux for another 24 years.

Logic Supply unveiled four Ubuntu-ready, Mini-ITX industrial PCs based on Intel Celeron (Bay Trail and Ivy Bridge) and Core (Haswell-ULT and Haswell) CPUs. Do aesthetics matter in on the factory floor? Logic Supply, which has been selling Ubuntu Linux ready embedded computers for years, has answered with a resounding yes with a new line of ML400G embedded PCs. The four new systems are the “smallest full-size Mini-ITX systems” ever built by the company, and offer a “sleek, exciting aesthetic with ultra-reliable, fanless and ventless engineering,” says Logic Supply.

Lennart Poettering, creator of the systemd system management software for Linux, says the open-source world is "quite a sick place to be in." He also said the Linux development community is "awful" – and he pins the blame for that on Linux supremo Linus Torvalds.

Let's reminisce. What was the first open source tool you ever used? Was it for work or fun? Maybe you were trying to start or finish a project and reached for a free and accessible tool? Or maybe you just have a preference for open source software? Tell us about it. We're collecting stories.

When you're dealing with audio files, you'll run into a few problems every so soften. This is especially true with voice recordings and audio that was converted to a digital format from a cassette tape or a vinyl record. One of the biggest problems is noise. This could be hissing or background noise like the sound of the wind or a loud air conditioning unit, or even someone inadvertently breathing into a microphone. No matter what the source is, that noise is distracting. And while it's difficult to eliminate all of the noise from a digital audio recording, it is possible to clean the file up so that the noise tolerable.

LinkSprite unveiled a “pcDuino Acadia 1? SBC that runs Linux or Android on a 1.2GHz Freescale i.MX6 Quad SoC and features eMMC flash and dual microSD slots. LinkSprite Technologies, which hosts the open source project for pcDuino single board computers, last month announced a pcDuino3Nano SBC, featuring a dual-core, 1GHz Cortex-A7 Allwinner A20 system-on-chip for only $39. At last weekend’s Maker Faire New York, the company unveiled a quad-core based SBC called the pcDuino Acadia 1. No pricing or availability information was released.

Qt Developer Days Europe is next Monday to Wednesday in Berlin. It features tutorials and talks on making the most of the Qt toolkit most KDE Software is based upon. Since Qt opened up its development process a large part of KDE Frameworks development has been to ensure close cooperation between the two projects. This has succeeded spectaularly well and at this Qt Dev Days an incredible over 50% of the speakers are active or past developers with KDE. Some highlights include The Designer's Cookbook by VDG master Jens Reuterberg, Dan Leinir Turthra Jensen talking about Calligra Gemini in 2-in-1 Office Suite, David Faure will talk about inqlude.org and the KDE Frameworks and David Edmundson will talk on Plasma - A flexible workspace shell. Look at the schedule to see many more. As usual slides from the talks should be up on the website after the event for those who can not be there. KDE e.V. is a partner organisation of Qt Dev Days with vice-president Aleix Pol representing our community to anyone who wants to find out more.
