Raspberry Pi

  • Raspberry Pi marks 2nd birthday with plan for open source graphics driver

    That “blob” is the closed source driver code that the Pi requires today. “In common with every other mobile graphics core, using the VideoCore IV 3D graphics core on the Pi requires a block of closed-source binary driver code (a ‘blob’) which talks to the hardware,” Upton wrote. “Our existing open-source graphics drivers are a thin shim running on the ARM11, which talks to that blob via a communication driver in the Linux kernel. The lack of true open-source graphics drivers and documentation is widely acknowledged to be a significant problem for Linux on ARM, as it prevents users from fixing driver bugs, adding features and generally understanding what their hardware is doing.”

  • A birthday present from Broadcom
  • Get Quake III running on Raspberry Pi using Broadcom’s open-source GPU drivers, earn $10K

    Broadcom has released open-source drivers and documentation for the graphics processor that’s used in the Raspberry Pi microcomputer, among other devices.

    “To date, there’s been a dearth of documentation and vendor-developed open source drivers for the graphics subsystems of mobile systems-on-a-chip (SoC),” Eben Upton, a Broadcom technical director and Raspberry Pi Foundation cofounder, wrote in a blog post. “Binary drivers prevent users from fixing bugs or otherwise improving the graphics stack, and complicate the task of porting new operating systems to a device without vendor assistance.”

  • Broadcom Open-Sources VideoCore IV 3D Graphics Stack

    In celebrating two years that Raspberry Pi has been around, Eben Upton has announced today that they are open-sourcing their OpenGL ES 1.1/2.0 graphics stack for the Broadcom VideoCore IV 3D graphics subsystem and it will help the Raspberry Pi with having a truly free graphics stack.

  • Android for All: Broadcom Gives Developers Keys to the VideoCore® Kingdom

    The community of open source mobile developers around the world are a vocal bunch – and here at Broadcom we’ve heard their call.

    To date, there’s been a dearth of documentation and vendor-developed open source drivers for the graphics subsystems of mobile systems-on-a-chip (SoC). Binary drivers prevent users from fixing bugs or otherwise improving the graphics stack, and complicate the task of porting new operating systems to a device without vendor assistance.

    But that’s changing, and Broadcom is taking up the cause.

  • A Nicely-Built 40-Core Raspberry Pi Cluster

    Raspberry Pi super-computing clusters have been attempted before, but usually they don’t turn out as nice as this new one that’s comprised of 40 Raspberry Pi boards inside of an acrylic chassis.

  • Teachers panicking over new computing curriculum

    Raspberry Pi director of Educational Development Clive Beale questioned whether the DfE is doing enough. He said, “I’m really worried it hasn’t been taken seriously enough.”

  • Raspberry Pi: giant hacks for a tiny board

    Usually there are two ways to look forward to buy a Raspberry Pi: first, think about a strange thing to make, and then go to the website; or second, buy the Raspberry Pi board having no idea of what you are going to do with it. Usually, I buy things and only after that I go through the Internet in search of inspiration and creative use cases for my new toys. That was the case with my first Raspberry Pi board: everyone seems to be able to put together his tiny PC with some parts (monitor, mouse and so on), a CPU and a lightweight Linux distribution, but what can we do that is totally crazy, mind-blowing and problem-solving?

PicoScope

  • Embedded World: PicoScope gets Linux software

    Pico Technology has released a beta version of the PicoScope 6 oscilloscope software for Linux.

    This is intended to support the use of Linux in the scientific and educational fields.

    The PicoScope 6 application runs on a PC to create oscilloscope, FFT spectrum analyser and measuring device functions.

  • Pico scopes now run Linux

    Users can save captures for offline analysis, share them with other PicoScope for Windows and PicoScope for Linux users, or export them in text, CSV and Mathworks MATLAB 4 formats. The only additional hardware needed is a USB oscilloscope.

  • A USB scope for Linux fans

    USB oscilloscopes are popular – only that the marketable supply is focused almost exclusively to Windows platforms. Pico Technology now redeems the growing flock of Linux users by offering such a software that runs under their preferred operating system.

What Else is New

  1. Team UPC Continues to Promote Illusion of UPC Progress Where There's None

    The core members of Team UPC in the UK spread obvious falsehoods in the media, probably in an effort to attract 'business' (consultation regarding something that does not exist)

  2. António Campinos: A True EPO Reformer or More of the Same?

    More unfortunate reminders that Campinos and Battistelli don't quite diverge on the big issues, they're just more than two decades apart in age (but the same nationality)

  3. Juve Has Confirmed That António Campinos is French

    The relationship between Campinos and Battistelli has a nationality aspect to it, not even taking into account the interpersonal connection which goes a long way back

  9. Confessions of EPO Insiders Reveal That European Patents (EPs) Have Lost Their Legitimacy/Value Due to Battistelli's Policies

    A much-discussed topic at the EPO is now the ever-declining quality of granted patents, which make or break patent offices because quality justifies high costs (searches, applications, renewals and so on)

  10. Patent Firms From the United States Try Hard to Push the Unitary Patent (UPC), Which Would Foment Litigation Wars in Europe

    The UPC push seems to be coming from firms which not only fail to represent public interests but are not even European

  11. In the Age of Alice and PTAB There is No Reason to Pursue Software Patents in the United States (Not Anymore)

    The appeal board in the US (PTAB) combined with a key decision of the Supreme Court may mean that even at a very low cost software patents can be invalidated upon demand (petition) and, failing that, the courts will invalidate these

  12. IAM is Wrong, the Narrative Isn't Changing, Except in the Battistelli-Funded (at EPO's Expense) Financial Times

    The desperate attempts to change the narrative in the press culminate in nothing more than yet another misleading article from Rana Foroohar and some rants from Watchtroll

  17. Rumours That António Campinos Initially Had No Competition at All (for Battistelli's Succession) Are Confirmed

    Succession at the EPO (mostly French) shows that there's little room for optimism and Battistelli's people are too deeply entrenched in the upper echelons of the EPO

  18. EPO Stakeholders Complain That the New Chairman Does Not Grasp the Issues at the EPO (or Denies These)

    Some information from inside the EPO’s Administrative Council, whose Chairman is denying (at least to himself) some of the core issues that render the EPO less competitive in the international market

  24. Articles in English and German Speak About the Decline in Quality of European Patents (Granted by the EPO)

    Heise and The Register, two sites that have closely watched EPO affairs for a number of years, speak about the real problem which is declining patent quality (or rushed examination) -- a recipe for frivolous litigation in Europe
