Mozilla: Doubling the Number of Content Processes in Firefox, SELinux With Firefox and Mobile Ports

  • Doubling the Number of Content Processes in Firefox

    Over the past year, the Fission MemShrink project has been working tirelessly to reduce the memory overhead of Firefox. The goal is to allow us to start spinning up more processes while still maintaining a reasonable memory footprint. I’m happy to announce that we’ve seen the fruits of this labor: as of version 66 we’re doubling the default number of content processes from 4 to 8.

    Doubling the number of content processes is the logical extension of the e10s-multi project. Back when that project wrapped up we chose to limit the default number of processes to 4 in order to balance the benefits of multiple content processes — fewer crashes, better site isolation, improved performance when loading multiple pages — with the impact on memory usage for our users.

    Our telemetry has looked really good: if we compare beta 59 (roughly when this project started) with beta 66, where we decided to let the increase be shipped to our regular users, we see a virtually unchanged total memory usage for our 25th, median, and 75th percentile and a modest 9% increase for the 95th percentile on Windows 64-bit.

  • Use Selinux with Firefox.
  • Get better password management with Firefox Lockbox on iPad [Ed: Apple in is NSA PRISM. There are back doors and data-sharing, passwords included.]

    We access the web on all sorts of devices from our laptop to our phone to our tablets. And we need our passwords everywhere to log into an account. This is why we made Firefox Lockbox, a way to securely track your Firefox passwords and access them anywhere.

  • Mozilla Firefox Lite Android App Officially Unveiled In India

    After getting a soft launch last year, Mozilla has officially launched the Firefox Lite Android version at an event in India.

    Additionally, Mozilla has collaborated with various companies such as Times Internet, DB Digital and MoMagic to enhance its presence in India.

    [...]

    For those who don’t know, Firefox Lite is now available in 15 markets in Asia including Bangladesh, Brunei, Cambodia, China, Hong Kong, India, Indonesia, Laos, Malaysia, Myanmar, Singapore, Thailand, Taiwan, the Philippines, and Vietnam.

    Lite-er versions of apps have been quite prevalent in developing countries such as India, where such apps prove apt for low-end smartphones catering to tier 2 and tier 3 segments, which could also prove beneficial for Mozilla.

New features in OpenStack Neutron

OpenStack is the open source cloud infrastructure software project that provides compute, storage, and networking services for bare-metal, container, and VM workloads. To get a sense of the core functionality and additional services, check out the OpenStack map. The platform has a modular architecture that works across industry segments because infrastructure operators can choose the components they need to manage their infrastructure in the way that best supports their application workloads. The modules are also pluggable to provide further flexibility and make sure they can be used with a specific storage backend or software-defined networking (SDN) controller. Neutron is an OpenStack project to provide a de-facto standard REST API to manage and configure networking services and make them available to other components such as Nova. Read more

  • Course Review: Applied Hardware Attacks: Rapid Prototying & Hardware Implants
    Everyone learns in different ways. While Joe is happy to provide as much help as a student needs, his general approach probably caters most to those who learn by doing. Lecture is light and most of the learning happens during the lab segments. He gives enough space that you will make mistakes and fail, but not so badly that you never accomplish your objective. If you read the lab manual carefully, you will find adequate hints to get you in the right direction. On the other hand, if you’re a student that wants to site in a classroom and listen to an instructor lecture for the entire time, you are definitely in the wrong place. If you do not work on the labs, you will get very, very, little out of the course. The rapid prototyping course is a good introduction to using the 3D printer and pcb mill for hardware purposes, and would be valuable even for those building hardware instead of breaking it. It really opened my eyes to the possibilities of these technologies. On the other hand, I suspect that the hardware implants course has limited application. It’s useful to learn what is possible, but unless you work in secure hardware design or offensive security that would use hardware implants, it’s probably not something directly applicable to your day to day.
  • Nulloy – Music Player with Waveform Progress Bar
    I’ve written a lot about multimedia software including a wide range of music players, some built with web-technologies, others using popular widget toolkits like Qt and GTK. I want to look at another music player today. You may not have heard of this one, as development stalled for a few years. But it’s still under development, and it offers some interesting features. It’s called Nulloy. The software is written in the C++ programming language, with the user interface using the Qt widget toolkit. It’s first release was back in 2011.

SmartArt and Contributors to LibreOffice

  • SmartArt improvements in LibreOffice, part 4
    I recently dived into the SmartArt support of LibreOffice, which is the component responsible for displaying complex diagrams from PPTX. I focus on the case when only the document model and the layout constraints are given, not a pre-rendered result. First, thanks to our partner SUSE for working with Collabora to make this possible.
  • Things to know if you are a new contributor to LibreOffice code
    When I began contributing code to LibreOffice, I faced some issues because I didn't know several facts that the other active contributors knew. This blog post summarizes some of those facts, and I hope it will be useful for other new contributors!
