  • Verified cryptography for Firefox 57

    Traditionally, software is produced in this way: write some code, maybe do some code review, run unit-tests, and then hope it is correct. Hard experience shows that it is very hard for programmers to write bug-free software. These bugs are sometimes caught in manual testing, but many bugs still are exposed to users, and then must be fixed in patches or subsequent versions. This works for most software, but it’s not a great way to write cryptographic software; users expect and deserve assurances that the code providing security and privacy is well written and bug free.

  • Busting the myth that net neutrality hampers investment

    This week I had the opportunity to share Mozilla’s vision for an Internet that is open and accessible to all with the audience at MWC Americas.

    I took this opportunity because we are at a pivotal point in the debate between the FCC, companies, and users over the FCC’s proposal to roll back protections for net neutrality. Net neutrality is a key part of ensuring freedom of choice to access content and services for consumers.

    Earlier this week Mozilla’s Heather West wrote a letter to FCC Chairman Ajit Pai highlighting how net neutrality has fueled innovation in Silicon Valley and can do so still across the United States.

    The FCC claims these protections hamper investment and are bad for business. And they may vote to end them as early as October. Chairman Pai calls his rule rollback “restoring internet freedom” but that’s really the freedom of the 1% to make decisions that limit the rest of the population.

  • Sysadmin war story: “The network ate my font!”

     

    Turns out the printer had a cache for fonts and was using the font cached from the earlier check image which included the font! Moreover, the Toronto and Hollywood offices were on a different printer maintenance schedule — and as part of the maintenance the printers are rebooted which clears the font cache!

  • The Harmful Consequences of Postel's Maxim draft-thomson-postel-was-wrong-01

     

    Jon Postel's famous statement in RFC 1122 of "Be liberal in what you accept, and conservative in what you send" - is a principle that has long guided the design of Internet protocols and implementations of those protocols.  The posture this statement advocates might promote interoperability in the short term, but that short-term advantage is outweighed by negative consequences that affect the long-term maintenance of a protocol and its ecosystem.

  • IBM Linux-only mainframe delivers breakthrough security
  • Kubernetes Meets HPC

    Anyone who has worked with Docker can appreciate the enormous gains in efficiency achievable with containers. While Kubernetes excels at orchestrating containers, high-performance computing applications can be tricky to deploy on Kubernetes.

    In this post, I discuss some of the challenges of running HPC workloads with Kubernetes, explain how organizations approach these challenges today, and suggest an approach for supporting mixed workloads on a shared Kubernetes cluster. We will also provide information and links to a case study on a customer, IHME, showing how Kubernetes is extended to service their HPC workloads seamlessly while retaining scalability and interfaces familiar to HPC users.

    31 organisations ask to improve public procurement of software

    Today, on 13 September 2017, 31 organisations are publishing an open letter. The letter calls for lawmakers to advance legislation requiring publicly financed software that has been developed for the public sector be made available under a Free and Open Source Software licence.

  • WordPress to ditch React library over Facebook patent clause risk

    Automattic, the company behind the popular open source web publishing software WordPress, has said it will be pulling away from using Facebook’s React JavaScript library over concerns about a patent clause in Facebook’s open source license.

    In a blog post explaining the decision yesterday, WordPress’ Matt Mullenweg said Automattic had hoped to officially adopt React for WordPress — noting it has already used it for the Calypso ground-up rewrite of WordPress.com a few years ago, and had started using it for its major Gutenberg core project.

    But he reveals it’s changed its mind after seeing Facebook dig in behind the patent clause — which was recently added to the Apache Software Foundation’s (ASF) list of disallowed licenses.

  • ​New IBM big iron for Linux

    IBM mainframes are alive, well, and being designed to make the most of Linux.

  • Create a Linux VM with these potential limitations in mind

    it involves creating a VM object and allocating hardware resources, such as memory, virtual network adapters and virtual CPUs. As simple as the creation process might be, however, the OS that will eventually be installed onto the VM requires some consideration. For example, the VM will need to be provisioned with enough memory to run the OS. In some cases, there may be additional considerations that need to be made beyond meeting the minimum hardware requirements of the OS. This can be especially true for a Linux VM.

  • Cairo Adds Support For OpenGL ES 3.0

    The Cairo 2D vector graphics library used by GTK, Firefox, WebKit, and many other programs finally has an OpenGL ES 3.0 back-end merged.

    Cairo supports many different backends from OpenGL to DirectFB to outputting as SVG/PDF/PostScript files as well as Skia, Direct2D, OpenVG, and other less notable code paths. Finally, OpenGL ES 3.0 is now supported by mainline Cairo.

  • Optimizing web servers for high throughput and low latency

    This is an expanded version of my talk at NginxConf 2017 on September 6, 2017. As an SRE on the Dropbox Traffic Team, I’m responsible for our Edge network: its reliability, performance, and efficiency. The Dropbox edge network is an nginx-based proxy tier designed to handle both latency-sensitive metadata transactions and high-throughput data transfers. In a system that is handling tens of gigabits per second while simultaneously processing tens of thousands latency-sensitive transactions, there are efficiency/performance optimizations throughout the proxy stack, from drivers and interrupts, through TCP/IP and kernel, to library, and application level tunings.

    There are numerous other commands for examining disks and file systems. Those described here are some of the most useful and informative. Using them periodically has advantages as the easiest way to spot problems is becoming so used to the output of commands such as these that you easily spot the kind of differences that might indicate problems.
