Code for Pakistan and Linux Foundation Event

  • Code for Pakistan to host Open Source Day for Women
    Open source refers to software with its source code publicly available for people to modify and share. However, it does not simply mean to write a source code and make it publicly available, it is also about collaborative participation, transparency, rapid growth and community-oriented development. The Open Source Day is an opportunity for women with a background in Computer Science to get started on Open Source Projects and network with mentors in the tech industry. It provides them an opportunity to come together and hone their tech skills.
  • Open Source Software Strategies for Enterprise IT
    Enterprises using open source code in infrastructure must understand both the risks and benefits of community-developed software. Professional open source management is a discipline that focuses on minimizing risk and delivering the benefits of open source software as efficiently as possible. For successful open source management, enterprises must adopt clear strategies, well-defined policies, and efficient processes. Nobody gets all this right the first time, so it’s also important to review and audit your policies for continuous improvement. Additionally, successful open source initiatives for enterprise IT must provide real ROI in acquisition, integration, and management.

Security Leftovers

Leftovers: BSD

  • BSD Mag: Understanding Unikernels by Russell Pavlicek
    The number of tasks which lend themselves to being unikernels is larger than you might think. In 2015, Martin Lucina announced the successful creation of a “RAMP” stack. A variant of the common “LAMP” stack (Linux. Apache, MySQL, PHP/Python), the “RAMP” stack employs NGINX, MySQL, and PHP each built on Rumprun. Rumprun is an instance of a Rump kernel, which is a unikernel system based on the modular operating system functions found in the NetBSD project. So even this very common solution stack can be successfully converted into unikernels.
  • Summary of the preliminary LLDB support project
    Operating systems can be called monitors as they handle system calls from userland processes. A similar task is performed by debuggers as they implement monitors for traced applications and interpret various events that occurred in tracees and are messaged usually with signals to their tracers. During this month I have started a new Process Plugin within LLDB to incept NativeProcessNetBSD - copied from NativeProcessLinux - implementing basic functionality and handling all the needed events in the MonitorCallback() function. To achieve these tasks, I had to add a bunch of new ptrace(2) interfaces in the kernel to cover all that is required by LLDB monitors. The current Process Plugin for NetBSD is capable to start a process, catch all the needed events correctly and if applicable resume or step the process.
  • NetBSD Making Progress On LLDB Debugger Support
    NetBSD developers have been implementing the relevant interfaces needed for the LLVM debugger to effectively monitor and work on the operating system. As part of that they have also improved some of their own documentation, provided new ptrace interfaces, and more. Those interested in LLDB and/or NetBSD can learn more about this debugging work via this NetBSD.org blog post.

Firefox 51 Released With FLAC Audio Support, WebGL 2.0 By Default

Firefox 51.0 just hit Mozilla's FTP servers for those wanting the latest version of this open-source web-browser. Firefox 51 isn't a big feature release for end-users but notably does have support for FLAC audio, at long last! Great to see the web browsers finally shipping support out-of-the-box for this open-source audio codec. Read more
