Battle for Wesnoth is one of the flagship open-source games, with a huge, dedicated community and an almost unmatched feature-completeness among the open-source games.
Linux and FOSS have already changed the world, and we’re just at the beginning. This is a great time to learn to be a maker, in contrast to being a mere consumer. Clicking buttons on a smartphone is not being tech-savvy; hacking and building the phone is.
Some people give Make Magazine the credit for launching the Maker Movement. Whether they launched it or just gave it a name, it is a real phenomenon, a natural evolution of do-it-yourselfers, inventors, and hackers in every generation. Remember Popular Mechanics, Popular Science, Hands-On (for Shopsmith projects), photography magazines, woodworking magazines, electronics…remember Heathkit? Remember when Radio Shack was still an electronics store? How about Edmund Scientific? That is still a wonderful playground of anatomical models, microscopes, telescopes, dinosaurs, prisms, lenses, chemistry sets, lasers, geology stuff, and tons more. All of these still exist, and have moved online like everything else. It’s a feast of riches, plus we have all the cool new stuff that Make Magazine covers. This is absolutely the best time to be a curious tech adventurer.
My family did not own a television until I was a teenager, and that was a good thing, because we had to be creative in our amusements. My parents and grandparents valued developing skills such as creative writing, playing musical instruments, carpentry, cooking, and whatever came to hand. We went camping in tents, rather than monstrous houses on wheels that are more luxurious than most stationary houses, and actually spent time outside. In the weather. With bugs and stuff. Our imaginations were not stunted by television, and nobody ever wailed “Oh but I can’t possibly learn to do that.”
Allow me to rant a wee bit. “I can’t possibly learn to do that.” There are few phrases I detest as much as that one. Of course you can. Anyone can learn to do anything.
So, you may be wondering, what does this have to do with Linux, Free software, and open source software? It has everything to do with these. High tech is about crafting solutions to real-world problems. If you’re not connected to the real world then you’re not going to have any fuel for your imagination, or any kind of useful purpose. Albert Einstein said “Imagination is more important than knowledge. For knowledge is limited to all we now know and understand, while imagination embraces the entire world, and all there ever will be to know and understand.”
Tech needs to solve real problems, and not just feed on itself. If I never hear the words “innovation” and “disruptive” I will be happy, because every week my inbox receives fresh influxes of recycled “innovation” and “disruptive” announcements of recycled product ideas. Because of this I rather enjoyed Silicon Valley Has Officially Run Out of Ideas:
“Over the years, the competition has proven to be something less than a fountainhead of world-changing ideas. Past champions include a conference-calling app, a car-sharing service that is not Uber or Lyft, and a half-hearted “Second Life” ripoff that hasn’t been heard from since 2012.”
Now I don’t know if Silicon Valley has really run out of ideas. I do know that chasing wealth, and wanting to build something useful are two different goals that don’t often intersect. Linux and FOSS freely give us tools for literally changing the world.
Doubtless this brands me as some kind of moldy old hippie, but I believe that life is about more than chasing wealth. Money is just a tool, and making it the end rather than the means to an end is inevitably corrupting. We have a limited number of days on the planet, and every morning when we wake up we have the same choice as all our days before: Do I live purposefully today, and try to make my little bit of the world a little better? Or do I fritter it away?
Linux and FOSS have already proven that they are genuinely innovative and transformational. The only limitation on the reach and influence of Linux and FOSS is our imaginations. Which brings us to the most essential element in fueling imagination: Diversity.
A lack of diversity leads to a failure of imagination. This is illustrated with brilliant sarcasm in Silicon Valley Has Officially Run Out of Ideas: “…a highly diverse panel of six other fabulously wealthy tech luminaries.”

Inspiration comes from real life, from everyday activities, from having relationships with diverse people and from observation. You don’t have to personally experience everything to understand the difficulties that other people face. Just pay attention. “Scratching your own itch” doesn’t need to be a selfish act that benefits no one else, though it is often interpreted that way. Rather, it means finding fulfillment and satisfaction in building something useful. Here are a few examples:
These are just a very few examples of the thousands of genuinely useful and innovative FOSS projects all over the world.
Steve Jobs famously recruited John Scully away from Pepsi to head up Apple by asking “Do you want to sell sugared water for the rest of your life? Or do you want to come with me and change the world?” We can ask ourselves the same question. Do we want to be mundane, or do we want to use the amazing and freely-available tools that Linux and FOSS give us to change the world?
The update is the second one released in a month to fix serious vulnerabilities in the popular open-source container virtualization technology.
SeaBED, a submersible robot powered by Linux, was recently used to scan the huge frozen ice sheets across Antarctica. That has helped scientists get detailed and high-resolution 3-D maps of the frozen continent for the first time. Researchers at the British Antarctic Survey will now be able to know more regions which had earlier been difficult to access because of the hostile conditions prevailing in the area.

I believe Docker is 2 steps forward for the world of DevOps and that the principles it promotes are forward-thinking and largely on-target for the future of a more secure, performant, and easy-to-manage cloud future. However, an alternative approach leveraging unikernels and immutable servers will result in smaller, easier to manage, more secure containers that will be simpler to adopt by existing enterprises.
As DevOps matures, the shortcomings of cloud application deployment and management are becoming clear. Virtual machine image bloat, large attack surfaces, legacy executables, base-OS fragmentation, and unclear division of responsibilities between development and IT for cloud deployments are all causing significant friction (and opportunities for the future).

How to install ProFTPD on CentOS 7.0
This document describes how to install and configure ProFTPD in CentOS 7.0 Server. ProFTPD is an FTP daemon for unix and unix-like operating systems. ProFTPD is developed, released and distributed under the GNU Public License (GPL), which basically establishes it as free software, meaning that it may be sold, licensed and otherwise manipulated in any way desired as long as full and complete source code either accompanies any ProFTPD packages or is made available by any and all sites that distribute pre-compiled binaries. The software can be modified by anyone at anytime, as long as all derived works also are licensed under the GNU Public License.
As we’ve reported several times, Google is introducing big changes in its Chrome browser, especially when it comes to how the browser handles extensions. If you’ve regularly used either or both of the most popular open source Internet browsers–Google Chrome and Mozilla Firefox–then you’re probably familiar with the performance and security problems that some extensions for them can cause.
In late 2013, Google decreed that the longstanding Netscape Plug-in API (NPAPI), which extensions have worked with for many years, is the source of many of the problems. And, Google decreed that extensions in the Chrome Web Store would be phasing out NPAPI support. Now, Google has delivered an update on its plan to remove NPAPI from Chrome, and the hope is that the move will improve the browser’s speed and stability, and limit complexity in its code base.
Google plans to block all plugins by default in January 2015, remove support entirely in September of 2015.
As of the 3.18-rc6release, 11,186 non-merge changesets have been pulled into the mainline repository for the 3.18 development cycle. That makes this release about 1,000 changesets smaller than its immediate predecessors, but still not a slow development cycle by any means. Since this cycle is getting close to its end, it’s a good time to look at where the code that came into the mainline during this cycle came from.
