  • The cpu_features library

    "Write Once, Run Anywhere." That was the promise of Java back in the 1990s. You could write your Java code on one platform, and it would run on any CPU implementing a Java Virtual Machine.

    But for developers who need to squeeze every bit of performance out of their applications, that's not enough. Since the dawn of computing, performance-minded programmers have used insights about hardware to fine tune their code.

  • Google Rolls Out cpu_features Library

    Google's cpu_features library makes it easier for detecting modern CPU capabilities like FMA, SSE, and AVX extensions when writing hand-tuned code.

  • 3 steps to reduce a project's failure rate [Ed: "Open Decision Framework" the latest Red Hat openwashing sound bite]

    It's no secret that clear, concise, and measurable requirements lead to more successful projects. A study about large scale projects by McKinsey & Company in conjunction with the University of Oxford revealed that "on average, large IT projects run 45 percent over budget and 7 percent over time, while delivering 56 percent less value than predicted." The research also showed that some of the causes for this failure were "fuzzy business objectives, out-of-sync stakeholders, and excessive rework."

  • Symphony Now Available on OpenFin Through Open Source Contribution to Symphony Software Foundation

    OpenFin, the desktop operating system built specifically for the needs of capital markets, announced today that it has publicly contributed code to the Symphony Software Foundation that allows, for the first time, any OpenFin customer to deploy Symphony Chat on the OpenFin operating system. The integration, currently in beta testing, enables seamless deployment and interoperability of Symphony alongside the expanding ecosystem of applications already running on OpenFin.

  • 2 startups are joining forces — and together they could pose a threat to Bloomberg

    Symphony, a messaging service that has gained some traction among Wall Street firms, has been integrated into OpenFin, an operating system built for financial-services, the two companies announced Thursday. 

    OpenFin hosts more than a hundred applications on its platform, and the integration means Symphony will be "interoperable" with those apps, the same way social media apps on your phone are able to talk with one another.

    “By enabling Symphony to run on the OpenFin operating system, we are making it easy for our mutual customers to unify the Symphony desktop experience with their other OpenFin-based apps," Mazy Dar, chief executive of OpenFin, said of the news. 

  • Gleif and Swift debut open source BIC-to-LEI mapping

    The Global Legal Entity Identifier Foundation (GLEIF) has published the first monthly relationship file that matches a Business Identifier Code (BIC) assigned to an organization against its Legal Entity Identifier (LEI).
    With the launch of this open source file, GLEIF and SWIFT have pioneered a cooperation model that, for the first time, enables market participants to link and cross-reference these key entity identifiers free of charge. This will significantly streamline entity verification processes and reduce data management costs.

  • Integrating continuous testing for improved open source security

    To protect yourself, you need mechanisms to prevent vulnerable packages from being added, and to ensure you get alerted and can quickly respond to new vulnerability disclosures. This chapter will focus on the first concern, discussing how you can integrate SCA vulnerability testing into your process, and prevent the addition of new vulnerable libraries to your code. The next chapter will deal with responding to new issues.

    Preventing new security flaws is conceptually simple, and very aligned with your (hopefully) existing quality control. Because vulnerabilities are just security bugs, a good way to prevent them is to test for them as part of your automated test suite.

Server: HTTP Clients, IIS DDoS and 'DevOps' Hype From Red Hat

  • What are good command line HTTP clients?
    The whole is greater than the sum of its parts is a very famous quote from Aristotle, a Greek philosopher and scientist. This quote is particularly pertinent to Linux. In my view, one of Linux’s biggest strengths is its synergy. The usefulness of Linux doesn’t derive only from the huge raft of open source (command line) utilities. Instead, it’s the synergy generated by using them together, sometimes in conjunction with larger applications. The Unix philosophy spawned a “software tools” movement which focused on developing concise, basic, clear, modular and extensible code that can be used for other projects. This philosophy remains an important element for many Linux projects. Good open source developers writing utilities seek to make sure the utility does its job as well as possible, and work well with other utilities. The goal is that users have a handful of tools, each of which seeks to excel at one thing. Some utilities work well independently. This article looks at 4 open source command line HTTP clients. These clients let you download files over the internet from the command line. But they can also be used for many more interesting purposes such as testing, debugging and interacting with HTTP servers and web applications. Working with HTTP from the command-line is a worthwhile skill for HTTP architects and API designers. If you need to play around with an API, HTTPie and curl will be invaluable.
  • Microsoft publishes security alert on IIS bug that causes 100% CPU usage spikes
    The Microsoft Security Response Center published yesterday a security advisory about a denial of service (DOS) issue impacting IIS (Internet Information Services), Microsoft's web server technology.
  • 5 things to master to be a DevOps engineer
    There's an increasing global demand for DevOps professionals, IT pros who are skilled in software development and operations. In fact, the Linux Foundation's Open Source Jobs Report ranked DevOps as the most in-demand skill, and DevOps career opportunities are thriving worldwide. The main focus of DevOps is bridging the gap between development and operations teams by reducing painful handoffs and increasing collaboration. This is not accomplished by making developers work on operations tasks nor by making system administrators work on development tasks. Instead, both of these roles are replaced by a single role, DevOps, that works on tasks within a cooperative team. As Dave Zwieback wrote in DevOps Hiring, "organizations that have embraced DevOps need people who would naturally resist organization silos."

Purism's Privacy and Security-Focused Librem 5 Linux Phone to Arrive in Q3 2019

Initially planned to ship in early 2019, the revolutionary Librem 5 mobile phone was delayed for April 2019, but now it suffered just one more delay due to the CPU choices the development team had to make to deliver a stable and reliable device that won't heat up or discharge too quickly. Purism had to choose between the i.MX8M Quad or the i.MX8M Mini processors for their Librem 5 Linux-powered smartphone, but after many trials and errors they decided to go with the i.MX8M Quad CPU as manufacturer NXP recently released a new software stack solving all previous power consumption and heating issues.

Hack Week - Browsersync integration for Online

Recently my LibreOffice work is mostly focused on the Online. It's nice to see how it is growing with new features and has better UI. But when I was working on improving toolbars (eg. folding menubar or reorganization of items) I noticed one annoying thing from the developer perspective. After every small change, I had to restart the server to provide updated content for the browser. It takes few seconds for switching windows, killing old server then running new one which requires some tests to be passed. Last week during the Hack Week funded by Collabora Productivity I was able to work on my own projects. It was a good opportunity for me to try to improve the process mentioned above. I've heard previously about browsersync so I decided to try it out. It is a tool which can automatically reload used .css and .js files in all browser sessions after change detection. To make it work browsersync can start proxy server watching files on the original server and sending events to the browser clients if needed. Read more
