Is Scratch today like the Logo of the '80s for teaching kids to code?

Open Source - Mié, 03/29/2017 - 09:02

Leave it to technology to take an everyday word (especially in the English language) and give it a whole new meaning. Words such as the web, viral, text, cloud, apple, java, spam, server, and tablets come to mind as great examples of how the general public's understanding of the meaning of a word can change in a relatively short amount of time.

Hence, this article is about a turtle and a cat who have changed the lives of many people over the years, including mine.

More Ways to Share with the Facebook Camera

Facebook - Mar, 03/28/2017 - 14:00
By Connor Hayes, Product Manager

We want to make it fast, fun and easy for people to share creative photos and videos with whomever they choose, for however long they choose— and the more we share with each other, the more open and connected our community can be. Today we’re starting to roll out a new camera with effects and two additional ways to share the photos and videos you take.

Camera Effects: Let Your Camera do the Talking
Starting this week on iOS and Android, you can tap on the camera icon on the top left corner of the Facebook app or swipe right from News Feed to try out the new in-app camera. The Facebook camera is packed with dozens of effects like masks, frames and interactive filters that you can apply to your photos and videos. Reactive effects let you interact with dynamic objects— like falling snow—and style effects apply an artistic filter to your video in real time, letting you turn your everyday selfie into a Picasso-style work of art.

We’re also partnering with brands to create masks for upcoming movies Alien: Covenant, Despicable Me 3, Guardians of the Galaxy Vol. 2, Power Rangers, Smurfs: The Lost Village and Wonder Woman.

Additionally, we’re including guest art from visual artists like Douglas Coupland and Hattie Stewart. We’ll regularly refresh the creative effects in the camera to give you fun new effects to explore.

Stories: Show Friends What You’re Up To 
The Instagram community has shown us that it can be fun to share things that disappear after a day, so in the main Facebook app we’re also introducing Facebook Stories, which lets you share multiple photos and videos as part of a visual collection atop News Feed. Your friends can view photos or videos your story for 24 hours, and stories won’t appear on your Timeline or in News Feed unless you post them there, too.

To add to your story, tap on the “Your Story” icon in the Stories bar at the top of News Feed.Direct: Easily Share With Exactly Who You Want
In addition to sharing to your Story, we know you may want to share your photos and videos with specific friends. We’ve also added Direct, an option that’s designed for sharing individual photos and videos with specific friends for a limited time.

When you send a photo or video via Direct, your friends will be able to view it once and replay it or write a reply. Once the conversation on the photo or video ends, the content is no longer visible in Direct.Over the coming months, we plan to introduce new ways for the Facebook community to create their own frames and effects that can be used on any photo or video created with the new Facebook camera. Our goal is for the camera to be a home to hundreds of dynamic and fun effects that give you new ways to connect with friends, family, and your community.

We hope that with the new Facebook camera, Stories and Direct, it will be easier than ever to see the world through each other’s eyes, and we can’t wait to see the photos and videos you create. In the meantime, here’s one of my own in my tropical island disguise, hiding from work with my cat Ebi.

How to build a smog sensor with a ESP8266 microcontroller

Open Source - Mar, 03/28/2017 - 09:03

Stuttgart, Germany has, like many other cities, a smog problem—even if it may be less severe than in other cities. The European Union has defined a threshold of on average 50 micrograms of dust particles per cubic meter in a 24-hour window of air to be allowed for a maximum of 35 days a year. For the last few years, actual values have been much higher for more than 35 days. There are governmental stations that measure the air pollution, but they can’t be everywhere for obvious reasons.

Survey seeks to discover the motivations behind open source contributions

Open Source - Mar, 03/28/2017 - 09:02

Peer production is one of three fundamental ways to organize human economic activity, along with markets and firms. Yet, although it underlies billions of dollars in open source software production, it is the least understood. Participants in open source are not organized in firms, where they would work under the supervision of managers and earn a salary, nor are they individuals in a market, responding to price signals.

14 ways being a runner is like working in tech

Open Source - Mar, 03/28/2017 - 09:01

I started running more than a decade after I started working in tech, but I quickly saw similarities between the two activities that take up most my time. I know—and have run with—many people in tech who also happen to be runners, but I suspect my observations work well for other fields, too. I've rounded up a list of ways being a runner is like working in tech.

Introducing Live Location in Messenger

Facebook - Lun, 03/27/2017 - 17:00

By Selena Wang, Product Manager, Messenger

Today we’re excited to announce a new way to share your location in Messenger. Our new Live Location feature makes it simple and seamless for you to choose to share where you are with your friends and family. This is rolling out globally and is available on both iOS and Android.

We’ve been testing this for a little while, and people tell us that Live Location is helpful when trying to coordinate with friends, telling people how close you are when you’re on your way to an appointment, or even sharing where you are with your roommate when you’re on your way home at night. You can share your Live Location with a group of friends in Messenger or just with one person — it’s up to you!

How It Works

  • To share your Live Location in a message on iOS, tap the Location icon or tap the More icon and then select Location.
  • With today’s update, you’ll see a map of your current location and the option to tap a blue bar to share your Live Location.
  • If you choose to share your Live Location, the person or people you share it with will be able to see where you are on a map for the next 60 minutes.
  • You’ll be able to see an estimate of how long it would take to get to others’ locations by car. (The ETA is seen by the person with whom the location is shared.)
  • You can stop sharing your Live Location at any time; just tap Stop Sharing.
  • A small clock in the lower right hand corner of the map will also let you know how much longer you’re sharing your location for.
  • For Android, tap the Location icon or tap the More icon and then select Location.
  • You’ll see a map of your current location and the option to tap a blue bar to share your Live Location for 60 minutes. Just like on iOS, you’ll have the option to stop sharing your Live Location by tapping Stop Sharing, and you’ll see how much longer you’re sharing your Live Location for via a small count down clock in the lower right hand corner of the map.

It’s still possible to share a static point on a map, too. For example, if you want to tell a friend which coffee shop to meet you at, tap the the location pin or the More icon, and then instead of choosing Share Live Location, tap the red pin in the upper right hand corner. From there, you can search for a place to share, or you can drag and drop the pin on the map. Then, tap Send.

Sharing your location in a Messenger conversation — either continuously for an hour with Live Location or as a static point — is completely optional. You are always in control. For additional information and instructions on sending or sharing a location in Messenger, please visit the Help Center.

Using vi-mode in your shell

Open Source - Lun, 03/27/2017 - 14:15

As a participant in the greater open source community, and more specifically as a member of the Fedora Project, I have the opportunity to meet with many people and talk about all kinds of interesting technical topics. One of my favorites is the "command line," or shell, because learning about how people use the shell proficiently can give you an insight into how they think, what kind of workflows they favor, and to some extent what makes them tick.

A Python script for fixing smart quotes in text

Open Source - Lun, 03/27/2017 - 09:01

About six years ago, we had a question on the Scribus mail list from someone who wanted to know whether there was an automated way to convert typewriter quotation marks to typographic quotes. In case you don't know what this means, typographic quotes (for example, and ) are sometimes referred to as curly quotes, rather than the incorrect versions on your typewriter (i.e., ").

SecureDrop and Alexandre Oliva are 2016 Free Software Awards winners

FSF - Dom, 03/26/2017 - 00:15

The Award for Projects of Social Benefit is presented to a project or team responsible for applying free software, or the ideas of the free software movement, to intentionally and significantly benefit society. This award stresses the use of free software in service to humanity.

This year, SecureDrop received the award, which was accepted by Conor Schaefer, Senior DevOps engineer for Freedom of the Press Foundation.

SecureDrop is an anonymous whistleblowing platform used by major news organizations and maintained by Freedom of the Press Foundation. Originally written by the late Aaron Swartz with assistance from Kevin Poulsen and James Dolan, the free software platform was designed to facilitate private and anonymous conversations and secure document transfer between journalists and sensitive sources. It has been used in newsrooms across the world, including the Intercept, Associated Press, the Washington Post, the Guardian, ProPublica, and the New Yorker.

In his speech, Stallman emphasized the importance of whistleblowers in the maintenance of a free society. "[SecureDrop] provides a necessary channel for whistleblowers to communicate through."

"At Freedom of the Press Foundation, we believe strongly that an obstinate and cantankerous press is fundamental to keeping populations informed and empowered," Schaefer said when accepting the award. "Secure and anonymous communication is more important today than ever before, and is vital for protecting high-risk individuals such as investigative journalists and their confidential sources.

"SecureDrop is one way we try to tackle that problem, by defending the right of the press to inform the public. The project is the result of hard work by security engineers and contributors in the free software community. Under the hood, it's a medley of free software tools, and could not exist without the vibrant free software movement to depend on.

"On behalf of Freedom of the Press Foundation, thank you, to everyone in the free software community, to those brave enough to fight to inform the public, and to the Free Software Foundation in particular. It's a privilege to work with you all. Keep fighting the good fight, we're right there with you."

The Award for the Advancement of Free Software goes to an individual who has made a great contribution to the progress and development of free software, through activities that accord with the spirit of free software.

This year, it was presented to Alexandre Oliva. An advocate of free software and the GNU Project, Oliva's impact has been felt far beyond his home in Brazil, from giving talks about free software to his role as maintainer of linux-libre, the fully free version of the kernel Linux. A leader in the robust Latin American free software community, he started a project to reverse engineer the proprietary software used by Brazilian citizens to submit their taxes to the government, giving people there the opportunity to complete this interaction almost entirely with free software, and offering inspiration (and free code) for those wanting to tackle this common issue elsewhere.

Stallman said that he is "especially impressed with [Oliva's] project Softwares Impostos. His project provides a free replacement for proprietary software required by the [Brazilian] government to submit taxes." Stallman praised the efficacy of Oliva's work and the dedication it showed to creating and maintaining software that has significant impact while respecting user freedoms. "In many years, he had his updates ready before the official software came out."

"I first met Richard 21 years ago," Oliva said. "That defined the rest of my life. I've shared his message—our message—since then and now I think I know that I've been doing it right."

Introducing Message Reactions and Mentions for Messenger

Facebook - Jue, 03/23/2017 - 16:00

By Drew Moxon, Product Manager, Messenger 

Messenger is a great way to communicate with just one person or with a group of people. Today, we’re introducing two new features that improve group conversations to make them more fun and useful.

Message Reactions
Message Reactions are the ability to react to an individual message with a specific emotion, quickly showing acknowledgement or expressing how you feel in a lightweight way. For example, if someone messages a photo of their cute pet, you could respond with the love reaction. Or, if someone is trying to coordinate dinner plans, you could easily respond with a yes or no reaction to indicate your preferences.

To add a reaction, press and hold any message, and then tap to make your selection from the love, smile, wow, sad, angry, yes and no emojis.

You’ll be able to see how people have reacted to a message in the lower corner of the message. There, you’ll see the reactions people selected alongside a number indicating how many people reacted to the message. Tapping on the emojis will show you which members of your conversation reacted which way.

When someone reacts to a message you sent, you’ll see a small animation when you’re looking at the conversation.

And, if you don’t have Messenger open, you’ll receive a notification that lets you know who reacted to your message and how.

Messenger Reactions use Messenger emojis. Messenger Reactions work in one on one conversations as well as group conversations and can be used to comment on any message — text, stickers, videos, GIFs and even other emoji.

Mentions
Mentions is a way to directly notify someone when they’ve been mentioned in a conversation. To mention someone, type the “@” symbol or start typing the first few letters of the name or nickname of the person you want to notify and select them from the list.

When the message is sent, it will appear with highlighted text for the others in the group to see.

When a person is mentioned, instead of simply seeing that someone responded in the conversation, he or she will receive a new kind of notification that lets them know they were called out specifically. That way, it’s easy to jump right back in to the conversation to answer someone’s question or to provide a response.

Everyone in the conversation can see the call out in the conversation, and everyone gets a notification just like before, but only the specified person in the group conversation gets a notification that they have been mentioned. You can choose to turn off these notifications at any time.

Reactions and Mentions will also be available for Work Chat in Workplace, our global communications platform for organizations to collaborate better. Both features will begin rolling out today and will be available globally in the coming days.

To learn more about Reactions and Mentions, be sure to visit the Help Center, here and here.

3 open source link shorteners

Open Source - Jue, 03/23/2017 - 08:03

Nobody likes an impossibly long URL.

They're hard to decipher. But sometimes, between a deep directory structure on a site, plus a large number of parameters tacked on to the end, URLs just begin to get unwieldy. And back in the days before Twitter added their own link shortener to their service, a long URL meant taking precious characters away from your tweets.
