2021年5月27日 · To address this feature, Free Software developers are creating peer-to-peer technologies that fully distribute power and privacy down to the end users. The LibreSocial network offers a glimpse of how this can work. There is no need to trust server administrators because the peer-to-peer architecture eliminates them altogether.

Please note: "Is it "open hardware" or "open source hardware?" This distinction is still under discussion. The term open source corresponds directly to programmatic source code, which holds true for hardware designs described in languages like Verilog hardware description language (HDL), but not for designs that may be described only in computer-ai...
Graham Seaman: "* Free Hardware Designrefers to a design which can be freely copied, distributed, modified, and manufactured. It does not imply that the design cannot also be sold, or that any hardware implementation of the design will be free of cost. All the same arguments about the meaning of 'freedom' between supporters of the Free Software Fou...
1. "Von Hippel observes that open-source hardware actually predates open-source software by centuries: people have always shared blueprints and sketches for such things as furniture and machinery. But the visibility of the open-source-software community "has created a new awareness of what has long been the historical practice in hardware," he says...
Summary on Why Open Hardware? By Patrick McNamara, Open Hardware Foundation, at http://www.osbr.ca/archive.php?issue=10§ion=Ar#A4: Lourens Veen who is on the board of directors for the Open Hardware Foundation or OHF summarized the answer to this question as follows: "Essentially, this is a problem of freedom. We users want to be free to use th...
Four Categories of Openness
Patrick McNamara, Open Hardware Foundation, at http://www.osbr.ca/archive.php?issue=10§ion=Ar#A4: "I believe hardware can be loosely placed into four categories of openness. They are, in order of least to most open: Closed, Open Interface, Open Design, and Open Implementation. Closed: Closed Hardwareis any hardware for which the creator of the hardware will not release information on how to make normal use of the hardware, in such a way that that information may be freely shared with othe...
Differences between open hardware, free hardware, open hardware design
By Graham Seaman, at http://opencollector.org/Whyfree/open_hardware.html "Many of the arguments over free hardware design consist of people from software and hardware backgrounds talking at cross-purposes. One cause of this is the simple fact that the word `software' refers both to source code and executables, while the words `hardware' and `hardware design' clearly refer to two different things. Using the word `hardware' as short-hand for both design and physical object is a recipe for confu...
Three-stage Roadmap for Implementation
Jamil Kathib: "The OpenHW road map can be divided into three main stages. If we can follow these stages we will have new industrial and technological revolution. Simple prototyping boards: A set of small generic prototyping boards can be designed to test small IP cores. The designers will use the available free tools which give lot of feedback to the EDA developers. Advanced boards and IP Cores: Designers will publish OpenHW cores and OpenSource software for the boards. The boards will be muc...

Problems and solutions of OpenHW
"There are many problems facing designers and prevent them from following the OpenHW methodology. Cost of EDA tools: individuals can not afford commercial EDA tools. This makes OpenSW developers start developing free EDA tools such as gEDA and Alliance which enables OpenHW designers to work at home. Cost of manufacture: HW manufacturing is relatively expensive, so OpenHW designers can use simulation or programmable logic devices to check their designs. Design protection: no one in the world l...
Pro: Graham Seaman
By Graham Seaman, at http://opencollector.org/Whyfree/open_hardware.html An important comment about the difficulty of developping it, as compared to open source: "At first blush, the open source model doesn't necessarily seem like a good fit for physical objects. The reason comes down to replication: with open source software, I can give you a copy of (for example) Firefox without losing my own. With open source hardware, at present the best I can give you a copy of the instructions as to how...
Pro
From http://w:ww.rowetel.com/blog/?p=14 "1. I think open software has been a good thing for the world, so I think open hardware is also good. 2. If closed IP makes a small amount of people a lot of money - does opening the IP make a moderate amount of money for a large amount of people?The latter seems a better outcome to me. It also suggests that open hardware benefits small companies more than large ones. 3. I think the specific benefit of open hardware is lower R&D costs. This is what is h...
From the Wikipedia article at http://en.wikipedia.org/wiki/Open_design "Open Design is a term that applies to the investigation and potential of open source and the collaborative nature of the internet to create physical objects. People apply their skills and time to projects for the common good, perhaps where funding or commercial interest is lack...

Discussion. "The tension between the ideals and practices of autonomous education projects is theorized most explicitly in Stefano Harney and Fred Moten’s eloquent essay. This tension is built into the concept of “undercommons”, which raises the question of how the subversive intellectual can be *in* but not *of* the university, i.e ...
Description. 1. Amanda B. Johnson: "the ride-sharing phenomenon has its BitTorrent equivalent called La’Zooz. Announced today at the Inside Bitcoins conference in Tel Aviv, Israel, La’Zooz functions on its own native crypto tokens, aptly called Zooz. They’ll be housed on the Bitcoin Blockchain and—get this—mined by proof-of-movement [1] .
2013年7月25日 · OGA: The “ Open Graphics Architecture ” is the gate-logic design of the Graphics Processing Unit (GPU) being developed to run on the OGD1 and later on the OGC1 cards. OGD1: The first “ Open Graphics Development ” card is designed to allow testing of the OGA in an FPGA device onto which new hardware designs can be loaded by special software.
