Ubuntu and Sun vs. Red Hat and JBoss?

Filed under
Software

In chess, there is a tactical motif called an x-ray. In it, the effect of an attacking piece is felt primarily not by the piece that's actively being attacked, but by the piece that is shielded from the direct attack by the attacked piece.

In the release of Ubuntu 7.04, with its optional Sun Java application server stack, the actively attacked piece is Red Hat Enterprise Linux, but JBoss is the real target.

Stephen O'Grady, a software industry analyst for RedMonk, describes the packing of Sun's open-source JEE (Java Enterprise Edition) 5 GlassFish application server, the Java SE Development Kit 6, Java DB 10.2, the Sun-supported version of the Apache Derby relational database manager, and the NetBeans IDE (integrated development environment) 5.5. as "a solid deal from a Sun perspective."

"I've argued for some time now that the Debian/Ubuntu/etc. non-commercial ecosystem is collectively larger than either the Red Hat or SUSE versions, and Ubuntu is obviously phenomenally popular in its own right, so this is an excellent channel opportunity," said O'Grady.

Early Benchmarks Of The Linux 4.9 DRM-Next Radeon/AMDGPU Drivers

While Linux 4.9 will not officially open for development until next week, the DRM-Next code is ready to roll with all major feature work having been committed by the different open-source Direct Rendering Manager drivers. In this article is some preliminary testing of this DRM-Next code as of 29 September when testing various AMD GPUs with the Radeon and AMDGPU DRM drivers. Linux 4.9 does bring compile-time-offered experimental support for the AMD Southern Islands GCN 1.0 hardware on AMDGPU, but that isn't the focus of this article. A follow-up comparison is being done with GCN 1.0/1.1 experimental support enabled to see the Radeon vs. AMDGPU performance difference on that hardware. For today's testing was a Radeon R7 370 to look at the Radeon DRM performance and for AMDGPU testing was the Radeon R9 285, R9 Fury, and RX 480. Benchmarks were done from the Linux 4.8 Git and Linux DRM-Next kernels as of 29 September. Read more

How to Effectively and Efficiently Edit Configuration Files in Linux

Every Linux administrator has to eventually (and manually) edit a configuration file. Whether you are setting up a web server, configuring a service to connect to a database, tweaking a bash script, or troubleshooting a network connection, you cannot avoid a dive deep into the heart of one or more configuration files. To some, the prospect of manually editing configuration files is akin to a nightmare. Wading through what seems like countless lines of options and comments can put you on the fast track for hair and sanity loss. Which, of course, isn’t true. In fact, most Linux administrators enjoy a good debugging or configuration challenge. Sifting through the minutiae of how a server or software functions is a great way to pass time. But this process doesn’t have to be an exercise in ineffective inefficiency. In fact, tools are available to you that go a very long way to make the editing of config files much, much easier. I’m going to introduce you to a few such tools, to ease some of the burden of your Linux admin duties. I’ll first discuss the command-line tools that are invaluable to the task of making configuration more efficient. Read more

Why Good Linux Sysadmins Use Markdown

The Markdown markup language is perfect for writing system administrator documentation: it is lightweight, versatile, and easy to learn, so you spend your time writing instead of fighting with formatting. The life of a Linux system administrator is complex and varied, and you know that documenting your work is a big time-saver. A documentation web server shared by you and your colleagues is a wonderful productivity tool. Most of us know simple HTML, and can whack up a web page as easily as writing plain text. But using Markdown is better. Read more
