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?




  • 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. From PTAB Bashing to Federal Circuit (CAFC) Bashing: How the Patent 'Industry' Sells Software Patents

    The latest tactics of the patent microcosm are just about as distasteful as last month's (or last year's), with focus shifting to the courts and few broadly-misinterpreted patent cases (mainly Finjan, Berkheimer, and Aatrix)

  2. Patent Maximalists Keep Coming Up With New Terms and Buzzwords to Bypass the Practical Ban on Software Patents

    The fightback against Section 101 and the US Supreme Court (notably Alice) seems to concentrate on old and new buzzwords, such as "Software as a Medical Device" ("SaMD") or "Fourth Industrial Revolution" ("4IR"), which the EPO recently paid European media to spread and promote

  3. News About Patents is Often Just Advertisements Composed Directly or Indirectly by Companies That Sell Patents and Patent Services

    Infomercials are still dominant among news about patents, in effect drowning out the signal (real journalism) and instead pushing agenda that is detached from reality, pertinent facts, objective assessment, public interest and so on

  4. Blocks and Paywalls Won't Protect the Patent Trolls' Lobby From Scrutiny/Fact-Checking

    Joff Wild and Benoît Battistelli have much in common, including patent maximalism and chronic resistance to facts (or fact-checking)

  5. China Has Become Very Aggressive With Patents

    China now targets other Asian countries/firms -- more so than Western firms -- with patent lawsuits; we expect this to get worse in years to come

  6. UPC/Battistelli Booster IAM Blames Brexit Rather Than EPO Abuses

    While the EPO is collapsing due to mismanagement the boosters of Team Battistelli would rather deflect and speak about Brexit, which is itself partly motivated by such mismanagement

  7. European Commission Again Urged to Tackle Abuses at the European Patent Office (EPO)

    Rina Ronja Kari is the latest MEP attempting to compel the Commission to actually do something about the EPO other than turning a blind eye

  9. TXED Courts Are Causing Businesses to Leave the District, Notably For Fear That Having Any Operations Based There is a Legal Liability

    A discussion about the infamous abundance of patent cases in the Eastern District of Texas (TXED/EDTX) and what this will mean for businesses that have branches or any form of operations there (making them subjected to lawsuits in that district even after TC Heartland)

  10. PTAB Hatred is So Intense Among the Patent 'Industry' That Even Scammers Are Hailed as Champions If They Target PTAB

    The patent microcosm is so eager to stop the Patent Trial and Appeal Board (PTAB) that it's supporting sham deals (or "scams") and exploits/distorts the voice of the new USPTO Director to come up with PTAB-hostile catchphrases

  11. The Patent 'Industry' is Increasingly Mocking CAFC and Its Judges Because It Doesn't Like the Decisions

    Judgmental patent maximalists are still respecting high courts only when it suits them; whenever the outcome is not desirable they're willing to attack the legitimacy of the courts and the competence of judges, even resorting to racist ad hominem attacks if necessary

  12. The Patent Trial and Appeal Board (PTAB) Carries on Enforcing § 101, Invalidating Software Patents and Upsetting the Patent 'Industry' in the Process

    A quick report on where PTAB stands at the moment, some time ahead of the Oil States decision (soon to come from the US Supreme Court)

  13. Luxembourg Can Become a Hub of Patent Trolls If the EPO Carries on With Its 'Reforms', Even Without the UPC

    With or without the Unified Patent Court (UPC), which is the wet dream of patent trolls and their legal representatives, the EPO's terrible policies have landed a lot of low-quality patents on the hands of patent trolls (many of which operate through city-states that exist for tax evasion -- a fiscal environment ripe for shells)

  14. The Patent 'Printing Machine' of the EPO Will Spawn Many Lawsuits and Extortions (Threats of Lawsuits), in Effect Taxing Europe

    The money-obsessed, money-printing patent office, where the assembly line mentality has been adopted and patent-printing management is in charge, is devaluing or diluting the pool of European Patents, more so with restrictions (monetary barriers) to challenging bad patents

  15. Links 17/3/2018: Varnish 6, Wine 3.4

    Links for the day

  16. Deleted EPO Tweets and Promotion of Software Patents Amid Complaints About Abuse and Demise of Patent Quality

    Another ordinary day at the EPO with repressions of workforce, promotion of patents that aren't even allowed, and Team UPC failing to get its act together

  17. Guest Post: Suspected “Whitewashing” Operations by Željko Topić in Croatia

    Articles about EPO Vice-President Željko Topić are disappearing and sources indicate that it’s a result of yet more SLAPP from him

  18. Monumental Effort to Highlight Decline in Quality of European Patents (a Quarter of Examiners Sign Petition in Spite of Fear), Yet Barely Any Press Coverage

    he media in Europe continues to be largely apathetic towards the EPO crisis, instead relaying a bunch of press releases and doctored figures from the EPO; only blogs that closely follow EPO scandals bothered mentioning the new petition

  19. Careful Not to Conflate UPC Critics With AfD or Anti-EU Elements

    The tyrannical Unified Patent Court (UPC) is being spun as something that only fascists would oppose after the right-wing, anti-EU politicians in Germany express strong opposition to it

  21. PTAB Continues to Increase Capacity Ahead of Oil States; Patent Maximalists Utterly Upset

    The Patent Trial and Appeal Board (PTAB) sees the number of filings up to an almost all-time high and efforts to undermine PTAB are failing pretty badly -- a trend which will be further cemented quite soon when the US Supreme Court (quite likely) backs the processes of PTAB

  22. Patent Maximalists Are Still Trying to Create a Patent Bubble in India

    Litigation maximalists and patent zealots continue to taunt India, looking for an opportunity to sue over just about anything including abstract ideas because that's what they derive income from

  23. EPO Staff Has Just Warned the National Delegates That EPO's Decline (in Terms of Patent Quality and Staff Welfare) Would Be Beneficial to Patent Trolls

    The staff of the EPO increasingly recognises the grave dangers of low-quality patents -- an issue we've written about (also in relation to the EPO) for many years

  24. The EPO is a Mess Under Battistelli and Stakeholders Including Law Firms Will Suffer, Not Just EP Holders

    As one last 'gift' from Battistelli, appeals are becoming a lot more expensive -- the very opposite of what he does to applications, in effect ensuring a sharp increase in wrongly-granted patents

  25. The EPO Under Battistelli Has Become Like China Under Xi and CPC

    The EPO is trying very hard to silence not only the union but also staff representatives; it's evidently worried that the lies told by Team Battistelli will be refuted and morale be affected by reality

  28. Willy Minnoye (EPO) Threatened Staff With Disabilities Said to Have Been Caused by the EPO Work Pressures

    Willy Minnoye, or Battistelli's 'deputy' at the EPO until last year, turns out to have misused powers (and immunity) to essentially bully vulnerable staff

  29. IAM and IBM Want Lots of Patent Litigation in India

    Having 'championed' lobbying for litigation Armageddon in China (where IBM's practicing business units have gone), patent maximalists set their eyes on India

  30. The Patent Trolls' Lobby (IAM) Already Pressures Andrei Iancu, Inciting a USPTO Director Against PTAB

    Suspicions that Iancu might destroy the integrity of the Office for the sake of the litigation ‘industry’ may be further reaffirmed by the approach towards patent maximalists from IAM, who also participated in the shaming of his predecessor, Michelle Lee, and promoted a disgraced judge (and friend of patent trolls) for her then-vacant role
