How to unzip a tar.gz file

Open Source - Lun, 07/03/2017 - 09:01

If you use open source software, chances are you'll encounter a .tar file at some point. The open source tar archive utility has been around since 1979, so it is truly ubiquitous in the POSIX world. Its purpose is simple: It takes one or more files and "wraps" them into a self-contained file, called a tape archive because when tar was invented it was used to place data on storage tapes.

News Feed FYI: Showing More Informative Links in News Feed

Facebook - Vie, 06/30/2017 - 20:00

By Adam Mosseri, VP, News Feed

Today we are making an update to help reduce low quality links in News Feed. We are always working to improve people’s experience in News Feed by showing more stories that we think people will find informative and entertaining.

Our research shows that there is a tiny group of people on Facebook who routinely share vast amounts of public posts per day, effectively spamming people’s feeds. Our research further shows that the links they share tend to include low quality content such as clickbait, sensationalism, and misinformation. As a result, we want to reduce the influence of these spammers and deprioritize the links they share more frequently than regular sharers. Of course, this is only one signal among many others that may affect the ranking prioritization of this type of post. This update will only apply to links, such as an individual article, not to domains, Pages, videos, photos, check-ins or status updates.

One of our core News Feed values is that News Feed should be informative. By taking steps like this to improve News Feed, we’re able to surface more stories that people find informative and reduce the spread of problematic links such as clickbait, sensationalism and misinformation.

Will This Impact My Page?
Most publishers won’t see any significant changes to their distribution in News Feed. Publishers that get meaningful distribution from people who routinely share vast amounts of public posts per day may see a reduction in the distribution of those specific links. As always, publishers should keep in mind these basic guideposts to reach their audience on Facebook and continue to post stories that are relevant to their audiences and that their readers find informative.

Expanding Find Wi-Fi Globally

Facebook - Vie, 06/30/2017 - 18:40

By Alex Himel, Engineering Director

Today we’re beginning to roll out Find Wi-Fi everywhere in the world on iPhone and Android. We launched Find Wi-Fi in a handful of countries last year and found it’s not only helpful for people who are traveling or on-the-go, but especially useful in areas where cellular data is scarce.

Find Wi-Fi helps you locate available Wi-Fi hot spots nearby that businesses have shared with Facebook from their Page. So wherever you are, you can easily map the closest connections when your data connection is weak.

To find Wi-Fi hotspots, open your Facebook app, click on the “More” tab and then “Find Wi-Fi.” Once in the “Find Wi-Fi” tab you may need to turn it on. You can then browse the closest available hotspots on a map, and learn more about the businesses hosting them.

Building Puppet's unofficial forge community

Open Source - Vie, 06/30/2017 - 09:00

A Puppet module might only be some 500 lines of code and a bunch of tests, but that doesn't mean it's effortless to maintain. Puppet modules should run on a range of operating systems and support a range of Puppet versions (and hence, Ruby versions)—and that in and of itself makes it quite challenging.

So while a single person could easily write a Puppet module, what happens when that person gets sick? Changes jobs? Or simply loses interest?

4 cool facts you should know about FreeDOS

Open Source - Jue, 06/29/2017 - 20:20

In the early 1990s, I was a DOS "power user." I used DOS for everything and even wrote my own tools to extend the DOS command line. Sure, we had Microsoft Windows, but if you remember what computing looked like at the time, Windows 3.1 was not that great. I preferred working in DOS.

Metrics Release: New Ways to Better Understand Interactions

Facebook - Jue, 06/29/2017 - 18:00

Great campaigns are powered by great insights. As people interact with businesses in new ways, marketers need to better understand actions driven by their online presence. We’ve heard feedback from businesses that they want more transparency and understanding around their Facebook performance. As part of our commitment to measurement, about every month or so we’ll release new metrics so that businesses have better ways to measure outcomes, all in one place. We’ll begin the series of metrics updates with features that capture new kinds of interactions with your ads or Page.

More Visibility On Ad Interactions

Getting visitors to your website or app greatly expands the potential for new customers. But slow-loading mobile sites or poor connections quickly cause many people to lose interest if they’re waiting for a page to load after clicking on an ad. To give you a better sense of the number of visitors that arrive to your website after a link click on an ad, we’re beginning to rollout a new metric called landing page views. This new metric will help businesses realize the importance of optimizing for a better mobile web experience. Businesses will be able to choose to optimize for landing page views when they use the traffic objective, finding more people who will actually arrive on their landing page after clicking on their ad.

We’ve also heard that businesses want more clarity around whether or not someone who clicks on an ad is a new or returning customer. The pre-impression activity breakdown is a new metric we’re introducing over the coming weeks that shows the number of people who have previously engaged with an advertiser’s website or app versus new visitors. We make the determination based on whether a site in recent weeks fired a pixel or triggered an app event associated with a business. Pre-impression breakdown is particularly helpful for businesses running dynamic ads for broad audiences, where the audiences expand beyond their own customers, and where ad creatives are generated dynamically based on associated product recommendations.

New Reporting On Page Interactions

We’re introducing three new reporting metrics to give Page owners a more complete understanding of how people learn about and interact with their businesses. These metrics will roll out to Pages over the coming weeks and can be viewed within the “overview” tab of Page Insights on desktop.

  • Follows: rather than only showing the total number of follows a business has, we’re now breaking out the number of follows a Page gains or loses over time, insights into where follows happen, follower demographics, and a breakdown of organic and paid follows. You can visit the Help Center for a refresher on understanding follows and likes.
  • Previews: people may come across your Page’s information without actually clicking on the Page. We’ll now show you the number of people who saw your Page’s information when hovering over your Page’s name on desktop.
  • Recommendations: people are already using recommendations as a way to get advice from friends, family, and local Groups on Facebook. We’ll now start showing the number of times a Page has been included under someone’s recommendation as a suggestion from friends and family.

We’ll continue to surface more metrics over the coming months as we get feedback and uncover new ways to provide actionable insights.

This is how you OpenStack: 6 new guides and tutorials

Open Source - Jue, 06/29/2017 - 09:03

Cloud infrastructure is a hugely in-demand skill. And if you're looking for an open source solution for your cloud infrastructure needs, chances are OpenStack is in that mix.

OpenStack is a huge collection of projects, providing solutions and integrations for nearly every part of the cloud stack. While this large scope makes it a powerful tool, it also means that it can be hard to keep up and learn about the full suite of projects, how to use them, how to customize them, and how to contribute code back to them.

Kubernetes: Why does it matter?

Open Source - Jue, 06/29/2017 - 09:02

Developing and deploying cloud-native applications has become very popular—for very good reasons. There are clear advantages to a process that allows rapid deployment and continuous delivery of bug fixes and new features, but there's a chicken-and-egg problem no one talks about: How do you get there from here? Building the infrastructure and developing processes to develop and maintain cloud-native applications—all from scratch—are non-trivial, time-intensive tasks.

Fifteen new devices from Technoethical now RYF-certified to respect your freedom

FSF - Mié, 06/28/2017 - 19:10

"We are excited that Technoethical has brought out such an impressive collection of hardware whose associated software respects user freedom. RYF certification continues to gain speed and momentum, thanks to companies like them. Users now have more options than ever when it comes to hardware they can trust, and I'm looking forward to what Technoethical will do next, " said the FSF's executive director, John Sullivan.

These are not the first devices from Technoethical to receive RYF certification. These fifteen new devices join Technoethical's Mini N150 WI-FI USB adapter TET-N150, certified in 2014. With these additions, Technoethical is now home to an incredible breadth of devices that users can trust to respect their freedom.

"In 2014 we started selling hardware compatible with fully free systems in order to fund the free software activism work that we've been doing with our foundation. Since then, we worked hard to build a hardware catalog that allows free software users to choose what best fits their computing needs, while also helping with the funding of different free software projects," said Technoethical founder, Tiberiu C. Turbureanu.

Today's certifications include multiple laptops: the TET-X200, the TET-X200T, the TET-X200s, the TET-T400, the TET-T400s, and the TET-T500 are all now available for purchase. Technoethical also received certification on two docking stations: the TET-X200DOCK for X200 series laptops and the TET-T400DOCK for T400 and T500 series laptops. The TET-D16 is the second mainboard certified by the FSF. Technoethical now offers a wide range of RYF-certified WiFi USB adapters, adding the TET-N150HGA, the TET-N300, and the TET-N300HGA to its line-up. They also have two internal WiFi devices: the TET-N300DB and the TET-N450DB. Finally, Technoethical now offers the first certified Bluetooth device — the TET-BT4 USB adapter.

"We thank the FSF for the opportunity to bring Technoethical hardware to LibrePlanet 2017 and have it reviewed for Respects Your Freedom certification. We consider their certification to be a confirmation of our ethical stance in technology. We also thank our customers for their trust and support. That enables us to contribute more to the building of the free society that FSF president Richard Stallman envisioned when he decided to start the GNU Project," said Turbureanu.

Certification details, including certified source code, can be found at

That said, there is one thing we can all agree on: The network cannot be trusted.

GitHub launches Open Source Friday 

Open Source - Mar, 06/27/2017 - 19:30

Open source software is developed by hobbyists and professionals alike. In fact, 65% of respondents to this year's GitHub open source survey who make contributions to open source projects do so as part of their job. However, the survey indicates that employers often lack a clear policy on employee contributions. A new project from GitHub aims to increase contributions to open source projects and to educate employers on why it's important.
