Every generation since the beginning of human existence has passed its value system, principles, methodologies, and skillsets on to the next generation. This passing on of information within cultures has been followed by the development of a systematic approach to learning techniques. Formal structures were created throughout the world to learn and apply these skillsets.

I use two different GUI text editors. Mousepad does my basic editing jobs in a single window, while Gedit gives me tabbed windows, syntax highlighting and (with the Draw Spaces plug-in) a toggle-able view of whitespace and tabs.

Unfortunately, both Mousepad and Gedit struggle with big text files, say 10 mb and up. In contrast, finding strings on the command line with grep is zippety-quick, even for huge text files. String replacement with sed is also pretty fast. I recently wrote a simple shell script for finding-and-replacing in some very large text files I was editing.

CherryTree is a powerful notes-taking application written in Python and GTK, which organizes your notes into so-called nodes and has rich-text markup formatting options, support for tables and images and many other features.

The “BB.Suit,” a wearable wireless router garment prototype created by Dutch design house By Borre, runs OpenWRT Linux on a TP-Link router board. Last month at South-by-Southwest (SXSW) in Austin, Texas, Dutch fashion designer Borre Akkersdijk unveiled his wearable computer called the BB.Suit. While most wearables are eye- or wrist-wear, the BB.Suit is an actual […]

The case was just weeks away from a jury trial, but US District Judge Anthony Trenga didn't let it get that far. In an opinion published Wednesday, Trenga found that IV's patents were simply abstract ideas: "nothing more than the mere manipulation or reorganization of data," he wrote. "At most, the patents describe a more efficient system or method for performing tasks than could be done without a computer, i.e. monitoring expenditures according to preset limits (the '137 Patent) or determining what would appeal to a particular user from a particular website (the '382 Patent.)"

Expunging the Heartbleed bug from vulnerable computers and gadgets is likely to take months, according to a leading vuln research firm. The cautionary assessment by Secunia comes as more and more products are judged to be vulnerable to the infamous OpenSSL security flaw.

Some cloud storage providers who hope to be on the leading edge of cloud security adopt a "zero-knowledge" policy in which says it is impossible for customer data to be snooped on. But a recent study by computer scientists at Johns Hopkins University is questioning just how secure those zero knowledge tactics are.

A targeted attack against an unnamed organization exploited the Heartbleed OpenSSL vulnerability to hijack web sessions conducted over a virtual private network connection.

KaOS 2014.04 has been released. KaOS is a desktop Linux distribution which was originally inspired by Arch Linux, but which is independently built and maintained using a rolling-release development model. It features the latest KDE desktop, the Calligra office suite and many popular KDE/Qt applications.

A round up of weekly events in Fedora.

The decision to fork OpenSSL is bound to be controversial given that OpenSSL powers hundreds of thousands of Web servers. When asked why he wanted to start over instead of helping to make OpenSSL better, de Raadt said the existing code is too much of a mess.

"Our group removed half of the OpenSSL source tree in a week. It was discarded leftovers," de Raadt told Ars in an e-mail. "The Open Source model depends [on] people being able to read the code. It depends on clarity. That is not a clear code base, because their community does not appear to care about clarity. Obviously, when such cruft builds up, there is a cultural gap. I did not make this decision... in our larger development group, it made itself."

Virtual Hosting With Proftpd And MySQL (Incl. Quota) On Ubuntu 14.04LTS This document describes how to install a Proftpd 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. In addition to that I will show the use of quota with this setup. This tutorial is based on Ubuntu 14.04LTS.

A $49 community-backed “Banana Pi” SBC is a Raspberry Pi lookalike, but uses a faster, dual-core Allwinner A20 SoC and adds HDMI and several other features. Shenzhen China based Lemaker.org has launched its Banana Pi single board computer for $49 plus shipping at Ali Express. The Banana Pi is aimed at Raspberry Pi users who […]

One Heartbleed vuln was too many for Theo de Raadt In the wake of the Heartbleed bug fiasco, members of the OpenBSD project have forked the popular OpenSSL library with the aim of creating a new version that they say will be more trustworthy.…

It's a container world now

We mentioned before about a couple big names talking up OpenGL and how to unlock many times performance gains with it, the GDC video is now up in the vault for all to see. Plus my thoughts on it all.

"Work on stuff that matters" is a famous call to action from founder and CEO of O'Reilly Media, Tim O’Reilly. But, how about working on stuff that matters while getting paid for it? There are an abundance of open source-related jobs out there if you’ve got the right skills.

For this new Long-Term Support release, major changes have been implemented, not only in Ubuntu, but in its derivatives as well. Trusty will be supported for five years for Ubuntu, Kubuntu and Ubuntu Kylin, while the other flavors using a different desktop environment will be supported as well, if only for three years. These include Xubuntu and Lubuntu.

Classical cryptography provides security based on unproven mathematical assumptions and depends on the technology available to an eavesdropper. But, these things might not be enough in the near future to guarantee cyber security. We need something that provides unconditional security. We need quantum cryptography.

I’ve been using Drupal, an open source content management system (CMS), for the websites I manage for over four years now. Though there may be some quirks in working with an open source product, I cannot imagine doing it any other way. Hesitations people may have when considering whether to use an open source product probably include the fact that you can’t just submit a helpdesk ticket when you run into a problem and expect a response within two business days. Most of the time, no single company or entity exists behind an open source project, like with a proprietary system. Instead open source has communities.

Monster phablet rooted at the factory for your pleasure Review While most Chinese smartphone OEMs started life making cheap tat and then slowly began moving upmarket, Oppo has taken a slightly different tack. Its devices have been fairly high-end from the get-go and the N1, initially released running Android 4.2 back in September 2013, made quite a splash.…

The following is an adapted transcription from the keynote address given at the 2014 SIGCSE conference by Hadi Partovi, founder of Code.org.   Thanks for the warm welcome! Last year, SIGCSE (Special Interested Group on Computer Science Education) was a week after our launch. It questioned our motives, and existence. We made a video, and that that video got 12 million views, so I built an organization around it.
