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. Patent Quality and Patent Scope the Unspeakable Taboo at the EPO, as Both Are Guillotined by Benoît Battistelli for the Sake of Money

    The gradual destruction of the European Patent Office (EPO), which was once unanimously regarded as the world's best, by a neo-liberal autocrat from France, Benoît Battistelli

  2. Bristows LLP's Hatred/Disdain of UK/EU Democracy Demonstrated; Says “Not Only Will the Pressure for UK Ratification of the UPC Agreement Continue, But a Decision is Wanted Within Weeks.”

    Without even consulting the British public or the European public (both of whom would be severely harmed by the UPC), the flag bearers of the UPC continue to bamboozle and then pressure politicians, public servants and nontechnical representatives

  3. Released Late on a Friday, EPO Social 'Study' (Battistelli-Commissioned Propaganda) Attempts to Blame Staff for Everything

    The longstanding propaganda campaign (framing staff as happy or framing unhappy staff as a disgruntled minority) is out and the timing of the release is suspicious to say the least

    Links for the day

  5. White Male-Dominated EPO Management Sinks to New Lows, Again

    Benoît Battistelli continues to make the EPO look like Europe's biggest laughing stock by attempting to tackle issues with corny photo ops rather than real change (like SUEPO recognition, diverse hiring, improved patent quality, and cessation of sheer abuses)

  6. Journalism 102: Do Not Become Like 'Managing IP' or IAM 'Magazine' (the Megaphones of the EPO’s Management)

    Another look at convergence between media and the EPO, which is spending virtually millions of Euros literally buying the media and ensuring that the EPO's abuses are scarcely covered (if ever mentioned at all)

  7. Journalism 101: Do Not Believe Anything That Benoît Battistelli and the EPO's Management Say (Also Don't Fall for the UPC Hype)

    A survey/review (or an overview) of recent articles about the EPO and why they're wrong (mostly because they parrot the official lies from Battistelli's department)

  8. Patent Law Firms, David Kappos, and IAM 'Magazine' Still Shelter Software Patents by Cherry-Picking and Lobbying

    Amid the gradual collapse of software patents in the United States there are disingenuous efforts to bring them back or maintain a perception that these patents are still potent

  9. Microsoft-Connected Patent Trolls Going Places and Suing Microsoft Rivals, Microsoft Wants More 'Linux Patent Tax'

    Microsoft-connected patent trolls like Larry Horn's MobileMedia are still attacking Microsoft rivals and Microsoft wants more money from Korea, after it attacked Linux with software patents over there (notably Samsung and LG)

    Links for the day

  14. Like Big Tobacco Lobbyists, Benoît Battistelli and Team UPC Are Just Chronically Lying and Manipulating Politicians With Their Lies

    Benoît Battistelli and Team UPC continue to meddle in politics and mislead the public (through the press) about patent quality as well the UPC, which is now in effect sunk inside the ashtray of history

  15. The EPO's 'Investigative' Function is Totally Out of Control and Continues to Get Bigger, Whitewashed by So-called 'Review'

    An update on the situation which still causes great unrest at the European Patent Office (EPO), namely abuse of staff by the so-called Investigative Unit (Eponia's equivalent of unaccountable secret services)

  16. Microsoft and Patent Law Firms in the United States Can't Stop Writing About McRo in a Coordinated Push to Resurrect Software Patents

    Microsoft is pursuing more Linux 'patent tax' (using software patents) and patent law firms are preoccupied flooding the media with their shameless self-promotion which is also software patents promotion

  17. For Abuse Like Plagiarism and Malpractice, the US Patent System is Still World Champion

    Low patent quality, abusive litigation (e.g. by patent trolls) and various other elements that globally discredit the USPTO are only symptoms of a wider problem, which is a greedy system motivated by neo-liberal values rather than professionalism and servitude

  21. With or Without the UPC (Which Will Probably Never Happen) Battistelli is Crushing the EPO and Ejects Experienced Staff, a Future Without Examination Possible

    A pessimistic but probably realistic take on what is happening at the European Patent Office (EPO), which is undergoing a silent transformation so wide-ranging that stakeholders deserve to know about it

  22. When EPO Liar-in-Chief Benoît Battistelli Defamed His Staff in Parliament, Comparing Them to Nazis and Criminals

    A reminder of the audacity of Benoît Battistelli, who in his capacity as a politician -- a problem in its own right -- slanders EPO staff

  23. After McRO v Namco Case (at CAFC) the Patent Microcosm Works Overtime to Produce Pro-Software Patents Propaganda, Smear the Supreme Court

    Increasingly desperate to convince people to pursue software patents and/or use their software patents to initiate growingly risky lawsuits (high risk of losing), the patent microcosm hugs McRO v Namco while distorting the complete record of the Court of Appeals for the Federal Circuit (CAFC) on this subject

  24. Poor Quality Control at the US Patent Office Gives Birth to 'Unpatent' and Gives a Voice to Critics

    The USPTO must up its game on patent quality (not relying on PTAB and the courts correcting its errors after the grants) or face growing backlash that tarnishes its public image

  25. Patent Trial and Appeal Board Under Attack by Law Firms, Which Will Soon Infiltrate It in the Form of 'Bar Association'

    The vultures that are patent law firms keep circling around PTAB and hoping to destroy it, if not from the outside then from the inside, potentially regressing and ruining great progress for US patent quality since Mayo and Alice

  26. EPO President Benoît Battistelli and Team UPC Are Still Lying, Don't Believe a Word They Say

    A rather bulky rebuttal to some of the latest misleading statements from EPO management and law firms that wish to expand/advance their own careers at the expense of the integrity of the European patent system

  30. Battistelli is Lying About Patent Quality While It Continues to Nosedive at the EPO as Part of His Neo-liberal 'Production' Strategy

    Battistelli, who tries to automate and streamline everything so as to maximise patent grants rather than examine applications properly, is making incredible claims that will almost certainly backfire on him
