  • ‘Biggest piece is culture:’ Stop chasing technology, start changing your agency

    Technology is changing rapidly, from centralized to distributed, from waterfall to agile, from Unix to Linux. And many times, federal agencies are finding themselves struggling to keep up and implement the solutions that improve their workflows and offer their customers the best experience.

    “Balancing modernization and innovation is the difficult part,” said David Cohn, Cloud Native SME at Red Hat. “Existing stuff, you need to update it. You need to be faster. How do you bridge it all together? That’s the glue, this agile integration.”

    Federal agencies often cite a lot of unique obstacles to modernization: strict budgetary constraints, unique mission requirements, bureaucratic red tape, the need to protect classified or otherwise sensitive data. They also tend to be more risk averse than private industry.

  • How automation can boost your security compliance

    Maybe you implement a CI system for an application using Jenkins or for the infrastructure using Ansible. That might take a few days on a single project. Then you might add a stage to your CI pipeline to do things such as static code analysis.

    As you automate each step of your CI pipeline, you should also automate the creation of compliance audit documentation as well, in each step. You will become more efficient and knowledgeable with the successful implementation of each of these steps, paving the way to expand automation further and further.

  • Migrating your applications to Openshift 4

    If you’re looking for a path to upgrade your Red Hat OpenShift 3.7+ cluster to OpenShift 4.2, you’re in luck. The Cluster Application Migration tool (CAM) was built to migrate stateful and stateless applications from a source cluster to a destination cluster.

    The initial intent of this tool is to address the OCP 3.7+ to OCP 4.2+ upgrade scenarios. That said, as requested by many Openshift users, it will also be possible to use this tool to migrate applications between OCP4 clusters.

    This tool is based on two popular open source projects: Velero and Restic.

    Half-Life: Alyx, the first Half-Life title in far too long has now been officially revealed with the Steam store page for it now available and you can also pre-purchase. However, their email clearly stated that Half-Life: Alyx will be "Free for owners of the Valve Index VR headset". This is a title built from the ground up for Virtual Reality, so only those with a VR kit will be able to play. Valve said it has "all of the hallmarks of a classic Half-Life game" including exploration, puzzle solving, visceral combat and a story that connects it all together with the Half-Life universe. Valve also said it will be compatible with "all PC-based VR headsets", it's powered by their own Source 2 game engine and it will release in March 2020.

  • Humble are giving away Serial Cleaner free for their Fall Sale now live

    You have around 72 hours to grab Serial Cleaner completely free, along with the start of the Humble Store Fall Sale. As always, there's tons of titles on sale. Plenty of indie games, plus multiple publishers have all put their games up with big discounts on them too.

  • BATTLETECH Heavy Metal has firmly stomped its way to release

    BATTLETECH Heavy Metal, the latest expansion to the turn-based strategy game that has you fight with massive lumbering 'mechs is out now. We've been told this is the definitive expansion, so it's likely to be the last as Harebrained Schemes move onto their next game. Quite an exciting expansion though and the naming of the expansion is very on point, since it comes with a bunch of classic 'mech designs from the original ​BATTLETECH​ board game plus a new 'mech designed just for Heavy Metal.

A Look At The GCC Compiler Tuning Performance Impact For Intel Ice Lake

For those wondering if it's worthwhile for performance recompiling your key Linux binaries with the microarchitecture instruction set extensions and tuning for Ice Lake, here are some GCC compiler benchmarks looking at that impact for the Core i7 1065G7 on the Dell XPS 7390. In particular, this article is looking at the affect on generated benchmark binaries when built under the following CFLAGS/CXXFLAGS configurations: -O3 -march=skylake - Just optimizing for conventional Skylake processors. -O3 -march=skylake-avx512 - Optimizing for Skylake AVX-512 processors like Skylake-SP/Skylake-X. The Skylake AVX-512 enables use of the AVX512F, CLWB, AVX512VL, AVX512BW, AVX512DQ and AVX512CD instructions. -O3 -march=icelake-client - Optimizing for Icelake client/desktop processors. New instructions exposed here not found with Skylake/Skylake-AVX512 include AVX512VBMI, AVX512IFMA, SHA, CLWB, UMIP, RDPID, GFNI, AVX512VBMI2, AVX512VPOPCNTDQ, AVX512BITALG, AVX512VNNI, VPCLMULQDQ, and VAES. Note there is also the "icelake-server" target for future Ice Lake Xeon Scalable processors where additionally PCONFIG and WBNOINVD are flipped on. Read more
