  • 5 ways to succeed at learning a programming language

    Whether you're taking up programming for the first time, or learning your 50th language, you might ask, "What's the best way to learn to program?" I surveyed dozens of people who taught themselves to program in Rust as part of my OSCON talk in 2016, and asked the expert autodidacts what advice they would give to others for picking up a new language. I found that despite their diverse backgrounds, all of my interviewees shared five common approaches to building new programming skills.

  • GitHub Developer Program shows bigger love

    The GitHub Developer Program (programme, if we’re using Her Majesty’s English) has been around for around three years now.

    Essentially, this initiative exists to encourage developers to test out application builds that integrate with GitHub.

  • GitHub Opens Developer Program to All

    GitHub Inc. has revamped its developer program with several changes, including opening it up to all developers for the first time.

    Previously, the three-year-old GitHub Developer Program was available to only those developers who had paid accounts at the open source code repository and software development platform specializing in Git-based version control.

If you're walking in the area of Boston's City Hall Plaza today, you might find yourself the subject of unique photo collage tomorrow.

Twenty-five local middle school girl are out roaming the city with digital cameras they built themselves as part of Red Hat Inc.'s (NYSE: RHT) CO.LAB initiative. On Friday, they'll turn the photos into a digital art installation that will be displayed at City Hall and Boston University.

The girls built the cameras on Wednesday out of Raspberry Pi computer kits — small, simple devices that teach the basics of programming. (Click through the gallery above to see the building process.)

  • Psychec: A Type Inference Engine For C, The C Language Meets Unification

    Here, at the Compiler's Laboratory of UFMG, we've been trying to understand the meaning of incomplete C code. How well can a parser reason about a source when declarations (or complete headers) are missing? In the C language, challenges appear already during parsing, since, not only syntax, but also semantic information (possibly absent) is required. Yet, the really cool challenges emerge when we want to reconstruct a partial program into a complete one that passes the type-checker.

  • GCC 7 Has Been Branched, GCC 8.0 Now On Master

    The GCC 7 mainline code-base hit the important milestone today of having zero P1 regressions -- issues of the highest priority -- and as such they branched the GCC7 code-base and GCC 7.1 RC1 is then being announced later this week as they prepare for this first stable release of GCC 7.

  • Uncovering 32 Qt best practices at compile time with clazy

    In a previous blog post we introduced clazy, a clang plugin which makes the compiler understand Qt semantics, allowing you to get compile-time warnings about Qt best practices ranging from unneeded memory allocations to misuse of API, including fix-its for automatic refactoring.

  • Clang-Based Tool Makes It Easy To Show Inefficient Qt Coding Mistakes

    Back in 2015 we wrote about the "Clazy" static analyzer for Clang as a way to uncover various coding shortcomings for KDE/Qt programs. Since then, Clazy has become much more capable.

    KDE developer and KDAB employee Sérgio Martins has written a new blog post about 32 of the best practices that Clazy can now spot at compile-time to point out to developers. He confirmed in a message to Phoronix that most of the issues brought up by Clazy are in regards to performance-sensitive areas that could be improved by the developer analyzing their code with this tool.

  • Automatic MySQL schema management with Skeema

    I first started using MySQL at a college IT job in 2003, and over the years I eventually began tackling much larger-scale deployments at Tumblr and Facebook. I’ve spent most of the past decade working on social networks, where massive high-volume database technology is fundamental to the product. I love the technical challenges present in that type of environment, as well as the huge potential impact of database automation and tooling. In companies with giant databases and many engineers, a well-designed automation system can provide a truly enormous increase in productivity.

  • 5 lessons learned when developing my first web app

    I developed my first web app as part of my final project in college. Instead of developing a web app only for the purpose of completing my project, I chose to develop one that could solve a real-world problem. I decided to create Cyber Manager, an online cyber cafe management system for cyber cafe administrators, which has been downloaded nearly 3,000 times since I first uploaded it on SourceForge.net in 2011. In this article, I'll walk through five lessons I learned during the process, which might help you during and after developing your own web app. I'll end with a quick look at Cyber Manager and how it works.

  • Secure Web Apps with JavaEE and Apache Fortress

    ApacheCon is just a couple months away -- coming up May 16-18 in Miami. We asked Shawn McKinney, Software Architect at Symas Corporation, to share some details about his talk at ApacheCon. His presentation -- “The Anatomy of a Secure Web Application Using Java EE, Spring Security, and Apache Fortress” will focus on an end-to-end application security architecture for an Apache Wicket Web app running in Tomcat. McKinney explains more in this interview.

  • Comprehend X86 Assembly Language with Open Source Books

    An assembly language is a low-level programming language for a computer, or other programmable device. Assembly language is used by almost all modern desktop and laptop computers. It is as close to writing machine code without writing in pure hexadecimal. It is converted into executable machine code by a utility program referred to as an assembler.

  • Xfce Session Manager 4.13 Released, Ported To GTK3

    An updated version of the Xfce4 session manager was released this Easter weekend.

    The xfce4-session 4.13.0 package was released today and it's a significant step forward for Xfce's session manager.

  • Relm: A GTK-Based GUI Library In Rust For Async GUI Apps

    With there being many Rustlang fans reading Phoronix, many of you will probably be interested in Relm: a new GUI library for Rust.

    Relm is a new crate/library for developing asynchronous GUI applications in Rust. Using GTK up to now in Rust looks rather messy, but Relm aims to change that and also make the applications more responsive by making the user-interface asynchronous and makes use of the language's futures capability.

  • Ask Hackaday: How Do You Python?

    Python is the Arduino of software projects. It has a critical mass of libraries for anything from facial recognition and neural networks to robotics and remote sensing. And just like Arduino, I have yet to find the killer IDE for Python. Perhaps I just haven’t tried the right one yet, but it could be that I’m just doing Python wrong.

  • Learn Swift Programming with No-Charge Books

    Swift is a new language, first appearing in 2014. It is friendly to new programmers, feels familiar to Objective-C developers, and the language is optimized for development. It was launched under a proprietary license, but Apple made the language open source in December 2015 by releasing Swift 2.2 and later under the Apache License 2.0. By open-sourcing Swift, developers are able to use the language for their own purposes and go beyond OS X, iOS and watchOS apps.

  • HHVM 3.19 Brings CLI Server Mode, Retranslate-All, Performance Boosts

    Facebook developers have put out their latest release of HHVM to empower this PHP interpreter as well as what powers their Hack programming language.

    HHVM 3.19 is the new release this week and it ships with some interesting experimental features. First up, there is a "Retranslate All" feature to re-translate all profiled code into optimized translations after it hits a specified number of requests. This re-translate all can be used for getting better performance, quicker warmups, and more. This experimental feature will likely go on by default in HHVM 3.20.

  • Intel's Beignet Lands LLVM 4.0 Backend Support

    While Intel's Beignet is a terrific project especially when it comes to being a leading open-source OpenCL implementation that works with OpenCL 2.0 on GPUs (something that can't be said for Radeon with its open-source OpenCL stack consistently lacking and Nouveau not really being usable either), the sad part of it is that Beignet is consistently slow in supporting new versions of LLVM.

  • Salaries for storage, networking pros continue to rise

    Though salaries overall remained flat, most tech pros (61 percent) reported receiving a salary increase in 2016 and 9 percent reported a decrease, according to the survey. Increased compensation is the most common motivator employers provided to tech pros in 2016 (18 percent), followed by flexible work location and ability to telecommute (14 percent) and more interesting and challenging assignments (12 percent), according to the survey.

  • QA in Production

    Gathering operational data about a system is common practice, particularly metrics that indicate system load and performance such as CPU and memory usage. This data has been used for years to help teams who support a system learn when an outage is happening or imminent. When things become slow, a code profiler might be enabled in order to determine which part of the system is causing a bottleneck, for example a slow-running database query.

    I’ve observed a recent trend that combines the meticulousness of this traditional operational monitoring with a much broader view of the quality of a system. While operational data is an essential part of supporting a system, it is also valuable to gather data that helps provide a picture of whether the system as a whole is behaving as expected. I define “QA in production” as an approach where teams pay closer attention to the behaviour of their production systems in order to improve the overall quality of the function these systems serve.
