Proprietary Software to Open Source - Migration Approach

Filed under
HowTos

As more and more IT and ISV executives understand the power and promise of open source, proprietary software companies are starting to adopt the open source model. I quoted this phenomena as 'Opening Up - Who, When, What' in one of my presentations in May 2004. Since then, Ingres, Open Solaris, and many other commercial products have been open sourced. Recent announcements on Google's Free Urchin (free software, not open) and Sun's PostgreSQL support stress the importance of 'Software Delivered As A Service (SAAS)'. Larry Augustin's editorial describes why open source model is better very well.

Just in the last week, 3 proprietary software companies informally discussed with me on how to open source their products. I suggested the following migration approach and thought would share the same for wider community consumption.

Linux Devices: Raspberry Pi, PIC32, Lime Micro

  • Apollo Lake COM Express module has onboard microSD and eMMC
    The COM Express Compact Type 6 “MSC C6C-AL” taps Intel’s Apollo Lake and offers up to 16GB DDR3L, microSD and optional eMMC, plus support for 5x PCIe slots.
  • How to create an Internet-in-a-Box on a Raspberry Pi
    If you're a homeschool parent or a teacher with a limited budget, Internet-in-a-Box might be just what you've been looking for. Its hardware requirements are very modest—a Raspberry Pi 3, a 64GB microSD card, and a power supply—but it provides access to a wealth of educational resources, even to students without internet access in the most remote areas of the world.
  • Squeeze Pi: Adventures in home audio
    The Squeezebox Touch provided a family-friendly interface to access our music library, either directly on the device or via a range of mobile applications. Logitech discontinued its development in 2012, but I was happy as they open sourced the Squeezebox's server software as Logitech Media Server and supplied the open source code used on the physical Squeezebox devices.
  • Evaluating PIC32 for Hardware Experiments
    PIC32 uses the MIPS32 instruction set. Since MIPS has been around for a very long time, and since the architecture was prominent in workstations, servers and even games consoles in the late 1980s and 1990s, remaining in widespread use in more constrained products such as routers as this century has progressed, the GNU toolchain (GCC, binutils) has had a long time to comfortably support MIPS. Although the computer you are using is not particularly likely to be MIPS-based, cross-compiling versions of these tools can be built to run on, say, x86 or x86-64 while generating MIPS32 executable programs.
  • Want a Raspberry Pi-powered PC? This $50 case turns the Pi into a desktop
    As long as you keep your expectations in check, it's perfectly feasible to run the latest Raspberry Pi as a desktop computer. However, the base Raspberry Pi 3 is a bare bones board, so anyone wanting to set it up as a desktop PC will need to buy their own case and other add-ons.
  • Open source LimeNET SDR computers run Ubuntu Core on Intel Core
    Lime Micro has launched three open source “LimeNET” SDR systems that run Ubuntu Core on Intel Core CPUs, including one with a new LimeSDR QPCIe board. Lime Microsystems has gone to Crowd Supply to launch three fully open source LimeNET computers for software defined radio (SDR) applications. The systems run Ubuntu “Snappy” Core Linux on Intel’s Core processors, enabling access to an open, community-based LimeSDR App Store using the Ubuntu Core snap packaging and update technology. The SDR processing is handled by three variations on last year’s open source LimeSDR board, which run Intel’s (Altera) Cyclone IV FPGA.

  • Data Center Networking Performance: New Apps Bring New Requirements
    Large cloud services providers such as Amazon, Google, Baidu, and Tencent have reinvented the way in which IT services can be delivered, with capabilities that go beyond scale in terms of sheer size to also include scale as it pertains to speed and agility. That’s put traditional carriers on notice: John Donovan, chief strategy officer and group president at AT&T technology and operations, for instance, said last year that AT&T wants to be the “most aggressive IT company in the world.” He noted that in a world where over-the-top (OTT) offerings have become commonplace, application and services development can no longer be defined by legacy processes.
  • Google Reveals a Powerful New AI Chip and Supercomputer
    The announcement reflects how rapidly artificial intelligence is transforming Google itself, and it is the surest sign yet that the company plans to lead the development of every relevant aspect of software and hardware. Perhaps most importantly, for those working in machine learning at least, the new processor not only executes at blistering speed, it can also be trained incredibly efficiently. Called the Cloud Tensor Processing Unit, the chip is named after Google’s open-source TensorFlow machine-learning framework.

    Virtualization has been a blessing for data centers – thanks to the humble hypervisor, we can create, move and rearrange computers on a whim, without thinking about the physical infrastructure. The simplicity and efficiency of VMs has prompted network engineers to envision a programmable, flexible network based on open protocols and REST APIs that could be managed from a single interface, without worrying about each router and switch.
