Creating a custom atomic scan plug-in

Brent Baude

In my previous article where I introduced atomic scan, I largely talked about using atomic to scan your containers and images for CVE Vulnerabilities. I also discussed how atomic scan had been architected to a plug-in approached so that you can implement your own scanners. The plug-ins do not have to focus on vulnerabilities, it could be as simple a scanner that collects information about containers and images. In this blog, I will walk through how you can create your...

Red Hat at the ISO C++ Standards Meeting (March 2016): Parallelism, Concurrency, and Coroutines

Torvald Riegel

Several Red Hat engineers recently attended the JTC1/SC22/WG21 C++ Standards Committee meetings in March 2016 in Jacksonville, Florida, USA. This post focuses on the sessions of SG1 (the standards committee sub-group 1 - for concurrency and parallelism) and on several proposals related to coroutines. The biggest news from a parallelism and concurrency (P&C) perspective is that the Parallelism Technical Specification v1 was voted into the working draft of the standard. This means that C++17 will offer support for several parallel...

Upcoming features in GCC 6

Jeff Law

The GCC project has traditionally made major releases yearly in the March/April timeframe. March is rapidly approaching and the GCC project's engineers are busy polishing things up for the GCC 6 release. I'm going to take a short break from my own release efforts to briefly talk about some of the new features. Warnings GCC strives to implement warnings which help developers catch errors at compile time rather than allow potentially dangerous code to be silently accepted and ultimately deployed...

Project: Remote Dependency Solving

Petr Hracek

Abstract This project (part of Red Hat Lab Q) was initiated by Jan Zeleny to accommodate low-end and low-cost devices, which have usually slower hardware, and has particular usefulness to Fedora. Three students (Josef Řídký, Michal Ruprich, Šimon Matěj) from Faculty of Information Technology (FIT VUT Brno, Czech Republic) began work on the project with me (Petr Hracek) as a leader of the team. The aim Let’s say we have a device with low-cost hardware and we have Fedora/EPEL Linux...

Upgrading the GNU C Library within Red Hat Enterprise Linux

Florian Weimer

Occasionally, there's a need for a new GNU C Library for a given application to run. For example, some versions of the Google Chrome browser started to warn users on Red Hat Enterprise Linux 7 that future versions of Chrome would not support their operating system. The Chromium source code contained a version check, flagging all versions of the GNU C Library (glibc) older than 2.19 as obsolete. This check has since been relaxed to 2.17 (the version in Red...

Lenexa C++ Meeting Report (Core Language)

Jason Merrill

Red Hat sent four engineers to the spring C++ meeting this year, in Lenexa, Kansas, a suburb of Kansas City. It was hosted by Perceptive Software, a division of Lexmark. The meeting went very smoothly overall; while there were some disagreements they were pretty cordial. The first disagreement came up during the Monday evening session when Bjarne was talking about his vision of C++17. He wants to see multiple big new features, lest people get bored with C++ after another...

Scala vs. Node.js as a RESTful backend server

Samuel Mendenhall

VS. I've been involved with full-stack development for a while now, especially stacks involving single page apps. When choosing to go with a single page webapp the backend concerns change. While any backend will do the job (think ruby, python, java, etc.) more emphasis is placed on the front-end stack as most of the time is spent in Javascript and less in the backend language since that is not where the UI logic resides. This is liberating in some senses...

The Eclipse Developer's guide to Clean Code (part 1)

Leo Ufimtsev

"Even bad code can function. But if code isn’t clean, it can bring a development organization to its knees" -- Clean Code We spent 10 times more time reading code than writing it. Thus keeping code clean is essential for maintainability and company growth, but doing it by hand can be tedious. Let's take a look at some of the clean code practices and how we can use Eclipse to re-factor code faster. Change inline comments to sub method calls...

The Eclipse Developer's guide to Clean Code (part 2)

Leo Ufimtsev

Last time we discussed de-duplicating some code. Today let us look into the effectiveness of refactored code, Java 8 support and moving/renaming code. But hold on, aren't method calls expensive? I took a course on compilers in University and did some research on the matter. In 1996 Java in-lining might have made sense. But nowadays the overhead that methods generate is relatively negligible, also the JVM is quite smart in optimizing bytecode by in-lining methods that make sense to in-line...
