3 mistakes to avoid when learning to code in Python

Open Source - Vie, 06/23/2017 - 09:01

It's never easy to admit when you do things wrong, but making errors is part of any learning process, from learning to walk to learning a new programming language, such as Python.

Here's a list of three things I got wrong when I was learning Python, presented so that newer Python programmers can avoid making the same mistakes. These are errors that either I got away with for a long time or that that created big problems that took hours to solve.

Take heed young coders, some of these mistakes are afternoon wasters!

A introduction to creating documents in LaTeX

Open Source - Vie, 06/23/2017 - 09:00

LaTeX (pronounced lay-tech) is a method of creating documents using plain text, stylized using markup tags, similar to HTML/CSS or Markdown. LaTeX is most commonly used to create documents for academia, such as academic journals. In LaTeX, the author doesn't stylize the document directly, like in a word processor such as Microsoft Word, LibreOffice Writer, or Apple Pages; instead they write code in plain text that must be compiled to produce a PDF document.

Our First Communities Summit and New Tools For Group Admins

Facebook - Jue, 06/22/2017 - 18:12

By Kang-Xing Jin, VP, Engineering

Today we hosted our first-ever Facebook Communities Summit in Chicago with hundreds of group admins where we announced new features to support their communities on Facebook.

Mark Zuckerberg kicked off by celebrating the role Groups play in the Facebook community and thanking the group admins who lead them. He also announced a new mission for Facebook that will guide our work over the next decade: Give people the power to build community and bring the world closer together.

An important part of delivering on our new mission is supporting group admins, who are real community leaders on Facebook. We’re adding several new features to help them grow and manage their groups:

  • Group Insights: group admins have told us consistently that having a better understanding of what’s going on in their groups would help them make decisions on how to best support their members. Now, with Group Insights, they’ll be able to see real-time metrics around growth, engagement and membership — such as the number of posts and times that members are most engaged.
  • Membership request filtering: we also hear from admins that admitting new members is one of the most time-consuming things they do. So, we added a way for them to sort and filter membership requests on common categories like gender and location, and then accept or decline all at once.
  • Removed member clean-up: to help keep their communities safe from bad actors, group admins can now remove a person and the content they’ve created within the group, including posts, comments and other people added to the group, in one step.
  • Scheduled posts: group admins and moderators can create and conveniently schedule posts on a specific day and time.
  • Group to group linking: we’re beginning to test group-to-group linking, which allows group admins to recommend similar or related groups to their members. This is just the beginning of ways that we’re helping bring communities and sub-communities closer together.

More than 1 billion people around the world use Groups, and more than 100 million people are members of “meaningful groups.” These are groups that quickly become the most important part of someone’s experience on Facebook. Today we’re setting a goal to help 1 billion people join meaningful communities like these.

In Chicago, we celebrated some of these groups built around local neighborhoods, shared passions and life experiences. For example, some of the groups and admins that attended include:

  • Terri Hendricks, who started Lady Bikers of California so that women who ride motorcycles could connect with each other, meet in real life through group rides, and offer each other both motorcycle-related and personal support. Terri says that when she started riding motorcycles it was rare to see other women who rode and that across the group, there is “nothing that these ladies wouldn’t do for each other.”
  • Matthew Mendoza, who started Affected by Addiction Support Group. The group is a safe space for people who are experiencing or recovering from drug and alcohol addiction, as well as their friends and family, to offer support and share stories.
  • Kenneth Goodwin, minister of Bethel Church in Decatur, Georgia, who uses the Bethel Original Free Will Baptist Church group to post announcements to the local community about everything happening at Bethel. He and the other admins will often share information about events, meeting times for their small group ministries, and live videos of sermons so people who cannot attend can watch from their homes.

We’re inspired by these stories and the hundreds of others we’ve heard from people attending today’s event. We’re planning more events to bring together group admins outside the US and look forward to sharing more details soon.

8 ways to contribute to open source when you have no time

Open Source - Jue, 06/22/2017 - 09:01

One of the most common reasons people give for not contributing (or not contributing more) to open source is a lack of time. I get it; life is challenging, and there are so many priorities vying for your limited attention. So how can you find the time in your busy life to contribute to the open source projects you care about?

Giving People More Control Over Their Facebook Profile Picture

Facebook - Jue, 06/22/2017 - 04:00

By Aarati Soman, Product Manager

Part of our goal in building global community is understanding the needs of people who use Facebook in specific countries and how we can better serve them. In India, we’ve heard that people want more control over their profile pictures, and we’ve been working over the past year to understand how we can help.

Today, we are piloting new tools that give people in India more control over who can download and share their profile pictures. In addition, we’re exploring ways people can more easily add designs to profile pictures, which our research has shown helpful in deterring misuse. Based on what we learn from our experience in India, we hope to expand to other countries soon.

Profile pictures are an important part of building community on Facebook because they help people find friends and create meaningful connections. But not everyone feels safe adding a profile picture. In our research with people and safety organizations in India, we’ve heard that some women choose not to share profile pictures that include their faces anywhere on the internet because they’re concerned about what may happen to their photos.

These tools, developed in partnership with Indian safety organizations like Centre for Social Research, Learning Links Foundation, Breakthrough and Youth Ki Awaaz, are designed to give people more control over their experience and help keep them safe online.

New Controls

People in India will start seeing a step-by-step guide to add an optional profile picture guard. When you add this guard:

  • Other people will no longer be able to download, share or send your profile picture in a message on Facebook
  • People you’re not friends with on Facebook won’t be able to tag anyone, including themselves, in your profile picture
  • Where possible, we’ll prevent others from taking a screenshot of your profile picture on Facebook, which is currently available only on Android devices
  • We’ll display a blue border and shield around your profile picture as a visual cue of protection

Deterring Misuse

Based on preliminary tests, we’ve learned that when someone adds an extra design layer to their profile picture, other people are at least 75% less likely to copy that picture.

We partnered with Jessica Singh, an illustrator who took inspiration from traditional Indian textile designs such as bandhani and kantha, to create designs for people to add to their profile picture.

If someone suspects that a picture marked with one of these designs is being misused, they can report it to Facebook and we will use the design to help determine whether it should be removed from our community.

In the history of computer games, very few are as influential as Colossal Cave Adventure. Initially developed in 1976 by Will Crowther and expanded by Don Woods in 1977, Adventure was the first interactive fiction game and inspired countless other computer games. Adventure directly or indirectly led to the entire corpus of text-based adventure games, and by extension, graphical adventure games.

Why aren't more researchers using open source?

Open Source - Mié, 06/21/2017 - 09:01

Academic researchers depend on a variety of highly specialized software to power their studies. The commercial software options in common use are expensive; either investigators must purchase a large number of licenses for common applications like data analysis tools, or they have to buy costly single licenses for specialized software, such as an application for a specific laboratory device.

What to know before you open source your project

Open Source - Mié, 06/21/2017 - 09:00

Your company is going to release an internal project as open source. Congratulations! You know your code is ready, but are you ready for all your new responsibilities?

Once a project has been released as open source, your company is not only responsible for the project, but also for the community that will form around it. This often requires changes to the development/build/release workflow. This is not about the code per se; it's about all the processes and infrastructure that surround the code that make the open source project successful.

A beginner's guide to collecting and mapping Twitter data using R

Open Source - Mar, 06/20/2017 - 12:36

When I started learning R, I also needed to learn how to collect Twitter data and map it for research purposes. Despite the wealth of information on the internet about this topic, I found it difficult to understand what was involved in collecting and mapping Twitter data. Not only was I was a novice to R, but I was also unfamiliar with the technical terms in the various tutorials. Despite these barriers, I was successful! In this tutorial, I will break down how to collect Twitter data and display it on a map in a way that even novice coders can understand.

Leaders are more powerful than they think

Open Source - Mar, 06/20/2017 - 09:00

I've noticed something interesting about the people whose names appear at the top of reporting structures in open organizations:

They tend to underestimate their influence.

Exhibit A: I was sitting across from the director of my department, asking for his thoughts on a new quarterly recognition program I was hoping we'd implement as a way of enhancing associate engagement. "And the prize could be lunch with you!" I exclaimed.

My director met me with silence and a skeptical look before stating bluntly, "That is not a prize."
