Angae means "Fog" in Korean. The term is widely used in parts of custom code used by the Red Star OS. We will lift the fog on the internals of North Korea's operating system. Our talk will provide information about how privacy is invaded for all users of Red Star OS and how an operating system designed by a totalitarian dictatorship works.

As far as web server performance is concerned, there are many different factors at play, e.g., front-end application design, network latency/bandwidth, web server configuration, backend caching, raw hardware capability, server load of shared hosting, etc. To compare and optimize web server performance under such a wide array of factors, we often perform load test (or […]Continue reading...

Open source software—software freely shared with the world at large—is an old idea. A guy named Richard Stallman started preaching the gospel in the early ’80s, though he called it free software. Linus Torvalds started work on Linux, the enormously successful open source operating system, in 1991, and today, it drives our daily lives—literally... if there’s one thing we learned in 2015, it’s that we shouldn’t underestimate the power of open source.

Apart from its physical form, a smartphone is indistinguishable to a normal computer so why not treat it as such? Even the oldest smartphones out there are considerably more powerful than desktop computers were even 20 years ago. You can install Debian, a version of the open-source Linux operating system on your device. Then just connect it to a monitor, sync up a Bluetooth keyboard and mouse, and you’re good.

What makes this free solution so interesting is how it comes pre-loaded with Bitcoin and OKCash clients, which should create a smoother out-of-the-box experience for users. Some synchronization for both clients might be needed during the initial startup, so make sure your Raspberry Pi has some external storage on board more than 50GB.

When the Raspberry Pi was first launched things were relatively straightforward – there was just one model to choose from. Fast forward to today, however, and you have no less than four major models to choose from. So, which one is best for your needs?

There are three main areas anyone wanting to get more intimately familiar with the Internet of Things should focus on: devices, cloud and analytics. With such a diversity of skills required, as Darshana Sugathan puts it, there can be no such thing as an "IoT expert."

The Xen Project has reported a new bug, XSA-169, that means "A malicious guest could cause repeated logging to the hypervisor console, leading to a Denial of Service attack." The fix is simple - running only paravirtualised guests - but the bug is a big blunder for another reason.

Options for those lacking a Linux render farm When it comes to video editing, Windows and Mac rule the screen. Professional apps by the likes of Adobe, Avid and Apple only run in the Win/Mac world and Apple even throws in a pretty sophisticated video editor (iMovie) for free.…

Without some help, the world of OpenStack can be an intimidating space. It seems as if there's always something new to learn, and the corpus grows larger every day. So what's a cloud administrator to do? read more

This year has been another great one for open science. At Opensource.com we published several great stories about open science projects that are changing the way we research, collaborate, and solve problems.

Just as well Azure and Office 365 are growing The last twelve months have been pivotal for Microsoft, the company which once promised to put a PC on every desk but now settles for a vague mission statement about “achieve more”.…

Congatec announced a “Conga-TS170” COM Express Basic module series based on Intel’s 6th Gen (“Skylake”) Core and Xeon processors, and aimed at high performance “server class” apps. Congatec is introducing a series of COM Express Type 6 Basic modules that are available with a selection of Intel’s 14nm 6th Generation Core (“Skylake”) processors, as well […]

Over a year ago now, I went looking for the best plugins to turn Vim into a full-fledged IDE. Interestingly, a lot of the comments on that post were about how Emacs already has most of these plugins built in, and was already a great IDE. Although I can only agree about Emacs' incredible versatility, […]Continue reading...

The Arrow Electronics SF2+ Development Kit, which targets security camera, communications, connected home, and Internet of Things (IoT) applications, is unusual in that it pairs the stripped down uClinux and U-boot with a Microsemi SmartFusion2 (SF2) SoC.

Fedora Election results Fedora's leadership structure is a mix of appointed and elected positions, with many of the appointed ones selected by other project members active in a particular area.

At the beginning of October I spent a week in Dublin sharing a room at a tiny bed and breakfast with two English students, each with really interesting stories to tell. Why was I there? I received diversity scholarship to attend LinuxCon 2015. I was so excited I didn't even mind the rain on the first day. But how did I get there? read more

Network Manager is a feature-rich network configuration service which is used by default in most Linux desktop environments nowadays. It provides automatic configuration of (wired/wireless) network interfaces, as well as VPN, mobile broadband and even Bluetooth connections. Network Manager is smart enough to automatically switch to the best (or the most recent) connection network, and […]Continue reading...

Three years ago, I wrote a series of articles titled "Getting Started with 3D Printing" that discussed the current state of the hobbyist 3D printing market from both the hardware and software angles. This is an incredibly fast-moving industry, and a lot has changed since I wrote those columns.
