  • Announcing Rust 1.30.1

    The Rust team is happy to announce a new version of Rust, 1.30.1. Rust is a systems programming language focused on safety, speed, and concurrency.

  • What is developer efficiency and velocity?

    As I previously mentioned I am currently in the information gathering phase for improvements to desktop Firefox developer efficiency and velocity. While many view developer efficiency and velocity as the same thing–and indeed they are often correlated–it is useful to discuss how they are different.

    I like to think of developer velocity as the rate at which a unit of work is completed. Developer efficiency is the amount of effort required to complete a unit of work.

    If one were to think of the total development output as revenue, improvements to velocity would improve the top-line and improvements to efficiency would improve the bottom-line.

  • Solid: a new way to handle data on the web

    The development of the web was a huge "sea change" in the history of the internet. The web is what brought the masses to this huge worldwide network—for good or ill. It is unlikely that Tim Berners-Lee foresaw all of that when he came up with HTTP and HTML as part of his work at CERN, but he has been in a prime spot to watch the web unfold since 1989. His latest project, Solid, is meant to allow users to claim authority over the personal data that they provide to various internet giants.

    Berners-Lee announced Solid in a post on Medium in late September. In it, he noted that despite "all the good we've achieved, the web has evolved into an engine of inequity and division; swayed by powerful forces who use it for their own agendas". Part of what he is decrying is enabled by the position of power held by companies that essentially use the data they gather in ways that run directly counter to the interests of those they gather it from. "Solid is how we evolve the web in order to restore balance — by giving every one of us complete control over data, personal or not, in a revolutionary way."

    Users' data will be stored in a Solid "pod" (sometimes "personal online data store" or POD) that can reside anywhere on the internet. Since Solid deliberately sets out to build on the existing web, it should not be a surprise that URLs, along with Uniform Resource Identifiers (URIs), are used to identify pods and specific objects within them. Pods also provide one place for businesses, including Inrupt, which was co-founded by Berners-Lee, to provide services for Solid. As he noted in his post, people are willing to pay companies like Dropbox for storage; hosting Solid pods would be a similar opportunity for Inrupt and others.

  • Should a programming course be mandatory for high school students?

    But further, understanding at least the basics of programming is important to being able to fully reap the benefits of open source. Having the code available to review, edit, and share under an open license is important, but can you really make use of the full power of an open license if you're locked in by your own inability to make the changes you wish to make?

  • A Summer Of Code Question

    This is a lightly edited response to a question we got on IRC about how to best apply to participate in Google’s “Summer Of Code” program. this isn’t company policy, but I’ve been the one turning the crank on our GSOC application process for the last while, so maybe it counts as helpful guidance.

    We’re going to apply as an organization to participate in GSOC 2019, but that process hasn’t started yet. This year it kicked off in the first week of January, and I expect about the same in 2019.

    You’re welcome to apply to multiple positions, but I strongly recommend that each application be a focused effort; if you send the same generic application to all of them it’s likely they’ll all be disregarded. I recognize that this seems unfair, but we get a tidal wave of redundant applications for any position we open, so we have to filter them aggressively.

    Successful GSOC applicants generally come in two varieties – people who put forward a strong application to work on projects that we’ve proposed, and people that have put together their own GSOC proposal in collaboration with one or more of our engineers.

Arc Menu Extension Now Lets You Pin Your Fave Apps to the Sidebar

If you’re a fan of the Arc menu extension for GNOME Shell you may be interested to hear that an update is on the way. A new version of the traditional-style app menu, which is particularly popular with Dash to Panel users, is currently pending approval over the GNOME Extensions website. What does it bring? Personalisation. Arc Menu replaces the full-screen app launcher in GNOME Shell with a more traditional ‘start menu’ design. It’s searchable, has bookmarks for important folders, shortcuts for key system actions, and lets you manage your session. It also lets you browse installed applications based one their category. The whole of the left-hand sidebar is dedicated to this purpose. Read more

Security: Mozilla Patch for Firefox and Getting Started with OpenSSL

  • Zero-Day Flaw In Firefox Is Getting Exploited By Hackers; Update Now!
    Mozilla has issued a warning of a zero-day flaw in Firefox browser that is currently being exploited in the wild. But the good news is that an emergency patch has been released for the same so you should update your browser now! The vulnerability was discovered by Google’s Project Zero security team...
  • Security vulnerabilities fixed in Firefox 67.0.3 and Firefox ESR 60.7.1
    A type confusion vulnerability can occur when manipulating JavaScript objects due to issues in Array.pop. This can allow for an exploitable crash. We are aware of targeted attacks in the wild abusing this flaw.
  • Getting started with OpenSSL: Cryptography basics
    This article is the first of two on cryptography basics using OpenSSL, a production-grade library and toolkit popular on Linux and other systems. (To install the most recent version of OpenSSL, see here.) OpenSSL utilities are available at the command line, and programs can call functions from the OpenSSL libraries. The sample program for this article is in C, the source language for the OpenSSL libraries. The two articles in this series cover—collectively—cryptographic hashes, digital signatures, encryption and decryption, and digital certificates. You can find the code and command-line examples in a ZIP file from my website. Let’s start with a review of the SSL in the OpenSSL name.

Python: Leading, Developing for Android and New RCs

  • Leading in the Python community
    Naomi began her career in the Classics; she earned a PhD in Latin and Ancient Greek with a minor in Indo-European Linguistics, as she says, "several decades ago." While teaching Latin at a private school, she began tinkering with computers, learning to code and to take machines apart to do upgrades and repairs. She started working with open source software in 1995 with Yggdrasil Linux and helped launch the Fort Wayne, Indiana, Linux User Group.
  • What’s the Best Language for Android App Developers: Java or Python?
    Few things can be so divisive among developers as their choice of programming languages. Developers will promote one over the other, often touting their chosen language’s purity, speed, elegance, efficiency, power, portability, compatibility or any number of other features. Android app developers are no exception, with many developers divided between using Java or Python to develop their applications. Let’s look at these two languages and see which is best for Android app developers.
  • Python 3.7.4rc1 and 3.6.9rc1 are now available
    Python 3.7.4rc1 and 3.6.9rc1 are now available. 3.7.4rc1 is the release preview of the next maintenance release of Python 3.7, the latest feature release of Python. 3.6.9rc1 is the release preview of the first security-fix release of Python 3.6. Assuming no critical problems are found prior to 2019-06-28, no code changes are planned between these release candidates and the final releases. These release candidates are intended to give you the opportunity to test the new security and bug fixes in 3.7.4 and security fixes in 3.6.9. We strongly encourage you to test your projects and report issues found to as soon as possible. Please keep in mind that these are preview releases and, thus, their use is not recommended for production environments.
