  • Introducing Fastify, a Speedy Node.js Web Framework

    Why have we written yet another web framework for Node.js? I am committed to making the Node.js platform faster, more stable and more scalable. In 2016, myself and David Mark Clements started Pino, which was designed to be the fastest logger for Node.js, and it now has four active maintainers and an ecosystem of hundreds of modules.

    Fastify is a new web framework inspired by Hapi, Restify and Express. Fastify is built as a general-purpose web framework, but it shines when building extremely fast HTTP APIs that use JSON as the data format. These are extremely common in both web and mobile software architectures, so Fastify could improve the throughput of the majority of applications.

  • The evolution of DevOps [Ed: DevOps is just a buzzword]

    A few years ago, I wrote that DevOps is the movement that doesn't want to be defined.

  • Why Python is a crucial part of the DevOps toolchain

    DevOps is built for agility and handling change. In this year’s Skill Up survey, Packt found that Python is one of the primary languages used by DevOps engineers. In this article, Richard Gall explores why Python is such a popular part of the DevOps toolchain.

    DevOps is a way of thinking; it’s an approach, not a specific set of tools. And that’s all well and good – but it only gives you half the picture. If we overstate DevOps as a philosophy or a methodology, then it becomes too easy to forget that the toolchain is everything when it comes to DevOps. In fact, DevOps thinking forces you to think about your toolchain more than ever – when infrastructure becomes code, the way in which you manage it, change it is constantly.

  • Updated AMD Zen Scheduler Model Lands For LLVM 6.0

    With the soon-to-be-released LLVM 5.0 there is the initial AMD Zen scheduler model for the compiler to benefit Ryzen / EPYC processors. But now already hitting the LLVM development code for LLVM 6.0 is a revised scheduler model.

openSUSE Tumbleweed Is Now Powered by Linux Kernel 4.17, KDE Plasma 5.13 Landed

As of today, the openSUSE Tumbleweed rolling operating system is now powered by the latest and most advanced Linux 4.17 kernel series, which landed in the most recent snapshot released earlier. Tumbleweed snapshot 20180615 was released today, June 17, 2018, and it comes only two days after snapshot 20180613, which added the Mesa 18.1.1 graphics stack and KDE Plasma 5.13 desktop environment, along with many components of the latest KDE Applications 18.04.2 software suite. Today's snapshot 20180615 continued upgrading the KDE Applications software suite to version 18.04.2, but it also upgraded the kernel from Linux 4.16.12 to Linux 4.17.1. As such, OpenSuSE Tumbleweed is now officially powered by Linux kernel 4.17, so upgrading your installs as soon as possible would be a good idea. Read more

OSS Leftovers

  • Using Open Source Software in a SecDevOps Environment
    On 21 June 2018 the Open Source Software3 Institute is hosting a discussion that should be of high interest to enterprise technologists in the DC/Northern Virginia, Maryland area. From their invite: Come hear from our panelists about how the worlds of Open Source Software and the Secure Development / Operations (SecDevOps) intersect and strengthen one another. SecDevOps seeks to embed security in the development process as deeply as DevOps has done with operations, and Open Source Software is a major factor in Security, Development, and Operations. Tickets are free, but you need to register soon because seating is limited.
  • TenFourFox FPR8b1 available
    TenFourFox Feature Parity Release 8 beta 1 is now available (downloads, release notes, hashes). There is much less in this release than I wanted because of a family member in the hospital and several technical roadblocks. Of note, I've officially abandoned CSS grid again after an extensive testing period due to the fact that we would need substantial work to get a functional implementation, and a partially functional implementation is worse than none at all (in the latter case, we simply gracefully degrade into block-level divs). I also was not able to finish the HTML input date picker implementation, though I've managed to still get a fair amount completed of it, and I'll keep working on that for FPR9. The good news is, once the date picker is done, the time picker will use nearly exactly the same internal plumbing and can just be patterned off it in the same way. Unlike Firefox's implementation, as I've previously mentioned our version uses native OS X controls instead of XUL, which also makes it faster. That said, it is a ghastly hack on the Cocoa widget side and required some tricky programming on 10.4 which will be the subject of a later blog post.
  • GNU dbm 1.15
    GDBM tries to detect inconsistencies in input database files as early as possible. When an inconcistency is detected, a helpful diagnostics is returned and the database is marked as needing recovery. From this moment on, any GDBM function trying to access the database will immediately return error code (instead of eventually segfaulting as previous versions did). In order to reconstruct the database and return it to healthy state, the gdbm_recover function should be used.

Server: GNU/Linux Dominance in Supercomputers, Windows Dominance in Downtime

  • Five Supercomputers That Aren't Supercomputers
    A supercomputer, of course, isn't really a "computer." It's not one giant processor sitting atop an even larger motherboard. Instead, it's a network of thousands of computers tied together to form a single whole, dedicated to a singular set of tasks. They tend to be really fast, but according to the folks at the International Supercomputing Conference, speed is not a prerequisite for being a supercomputer. But speed does help them process tons of data quickly to help solve some of the world's most pressing problems. Summit, for example, is already booked for things such as cancer research; energy research, to model a fusion reactor and its magnetically confined plasma tohasten commercial development of fusion energy; and medical research using AI, centering around identifying patterns in the function and evolution of human proteins and cellular systems to increase understanding of Alzheimer’s, heart disease, or addiction, and to inform the drug discovery process.
  • Office 365 is suffering widespread borkage across Blighty
     

    Some users are complaining that O365 is "completely unusable" with others are reporting a noticeable slowdown, whinging that it's taking 30 minutes to send and receive emails.
