An anonymous reader quotes a report from The Guardian: Just 100 companies have been the source of more than 70% of the world's greenhouse gas emissions since 1988, according to a new report. The Carbon Majors Report (pdf) "pinpoints how a relatively small set of fossil fuel producers may hold the key to systemic change on carbon emissions," says Pedro Faria, technical director at environmental non-profit CDP, which published the report in collaboration with the Climate Accountability Institute. The report found that more than half of global industrial emissions since 1988 -- the year the Intergovernmental Panel on Climate Change was established -- can be traced to just 25 corporate and state-owned entities. The scale of historical emissions associated with these fossil fuel producers is large enough to have contributed significantly to climate change, according to the report. ExxonMobil, Shell, BP and Chevron are identified as among the highest emitting investor-owned companies since 1988. If fossil fuels continue to be extracted at the same rate over the next 28 years as they were between 1988 and 2017, says the report, global average temperatures would be on course to rise by 4C by the end of the century. This is likely to have catastrophic consequences including substantial species extinction and global food scarcity risks.

AmiMoJo writes: A study by Rutgers University and Microsoft has found that hard drives are more prone to failure due to high levels of humidity [PDF] than high temperature. With a view to 'free cooling' data centres (using low external air temperature for cooling to save power), the paper notes that humidity related malfunctions of the driver controller / adapter are the dominant cause of drive failure. The good news is that while the researchers found that high relative humidity was a significant factor in drive failures, "[S]oftware availability techniques can mask them and enable freecooled operation, resulting in significantly lower infrastructure and energy costs that far outweigh the cost of the extra component failures."

mask.of.sanity writes "Google has revealed details on its Beyond Corp project to scrap the notion of a corporate network and move to a zero-trust model. The company perhaps unsurprisingly considers the traditional notion of perimeter defense and its respective gadgetry as a dead duck, and has moved to authenticate and authorize its 42,000 staff so they can access Google HQ from anywhere (video). Google also revealed it was perhaps the biggest Apple shop in the world, with 43,000 devices deployed and staff only allowed to use Windows with a supporting business case."

Taco Cowboy writes with news on the slipping schedules in the move toward both larger wafers and 3D integrated circuits in the semiconductor fab world. From the articles: "TSMC ... said it planned to start mass-producing next-generation 450mm wafers using advanced 10-nanometer technology in 2018. The advanced 10-nanometer chips could first be used in mobile devices and other consumer electronics, like game consoles, that demand high-performance and low power consumption. The plan was included in the latest technology roadmap unveiled by TSMC about one year after the chipmaker attributed its delay in making 450mm wafers, originally scheduled in 2015, to semiconductor equipment suppliers' postponement in developing advanced equipment for manufacturing amid the industrial slump. Chipmakers can get 2.5 times more chips from a 450mm wafer than from a 300mm wafer ... The industry's gradual migration toward 3D ICs with through-silicon vias (TSV) is unlikely to happen until 2015 or 2016, according to sources at semiconductor companies. Volume production of 3D ICs was previously estimated to take place in 2014. Leading foundries and backend assembly and test service companies have all devoted much of their R&D efforts to TSV development, and are making progress. The major players are believed to be capable of supporting 3D ICs by 2014, but the emerging technology going into commercial production may not take place until around the 2015-16 timeframe." Probably one of the most interesting presentations at HOPE9, "Indistinguishable From Magic: Manufacturing Modern Computer Chips," covered modern semiconductor fabrication and why these things are cool. If you're interested in more background (what do all of those TLAs mean?), check out the slides / audio (or attached video of the presentation from YouTube).

Project Byzantium calls itself Ad-hoc wireless mesh networking for the zombie apocalypse. It's also potentially useful for less-thrilling emergencies, such as floods, earthquakes, and political uprisings (or getting everyone at the office their /. fix when the network goes down). The latest version debuted at the HOPE (Hackers on Planet Earth) conference in July, 2012. You can download your very own copy of Byzantium any time you like. Hopefully you will then burn a dozen or so CDs (it's compact enough that it doesn't need a DVD) for friends and neighbors, so that if you suddenly see zombies approaching and your regular ISP has already been overrun and isn't working, you can set up a wireless mesh network and coordinate your anti-zombie efforts. And you won't even need to use the command line. (slides and audio of their presentation)

Four years ago, there were around ten hackerspaces across America; today, Hackerspaces (Techshops, Makerspaces) are within driving distance of a good chunk of the population. The RepRap can be assembled for a moderate price, and those with a bit more cash to burn can get one preassembled from multiple sources. Makerfaires are held in most major cities, sites like Instructables and Hackaday are thriving, and all things "Maker" are cool. Far McKon was at HOPE 9 giving an update on how far community fabrication has come since his 2008 presentation at the The Last HOPE (mp3 of the talk), what threats lie on the horizon, and where we might find ourselves in another four years.

Update: 09/20 21:02 GMT by U L : There's an audio recording of the talk available.

Much has improved in the last four years. 3D printers for one have gone from being rare and expensive items to something you can build with a reasonable effort, or purchase for a mere arm & leg instead of your first born. The copyleft nature of the 3D printer community and active competition between folks selling them is certainly reminiscent of the early days of commercial Free Software (making things quite exciting).

Hackerspaces have spread like wildfire, encouraging cooperation and granting access to DIY manufacturing tools to the masses without forcing everyone to shell out lots of money.

McKon admits that electronics kits are only a bit more accessible than they were in 2008 — Arduino, Beagleboard, Raspberry Pi, et al are certainly welcome — but we're nowhere near the "building hardware being as easy as software" dream McKon predicted in 2008. He predicts that four years from now will see about as much incremental change; hardware is hard.

On the other hand, Laser cutters haven't really budged in cost (they were around $8000 then, and ... surprise, $8000 now). But, hey, what's your local Hackerspace for? McKon speculated that laser cutters have been produced by entrenched proprietary vendors which have no profit-motive to decrease prices. Entering the market is far more challenging than jumping into a market with open hardware participants, something echoed later in the talk when McKon noted that Open Source ideals more easily infiltrated upcoming industries than entrenched ones generally (where's my Open Source fridge?).

Software for 3D printing still sucks. OpenSCAD is workable but difficult, Blender isn't really suited for the task, and in any case the bar to generating a model that can actually be printed is way too high. During the Q&A someone mentioned that Autodesk was adding features aimed at 3D printing; McKon noted that Open Source design tools were encroaching on Autodesk et al's turf. Proprietary software packages are going to have to improve (great for their users), but Open Source development has distinct advantages that, at least in this area, are leading to ever-accelerating development. Still, he emphasized that the only way Open Source tools would win is if people contributed. So go and contribute, or else.

The Hackerspace community has spread the ideals of Free Culture into device manufacturing. McKon sees two business models: Seed and Feed. In the Feed model, you are a consumer and the device is closed. You can see this in proprietary additive printers where the extrusion material often comes in closed cartridges ala inkjet printers and the manufacturer doesn't release information on controlling the device. The Feed model prevails in the world today.

The Seed model is a mixture of DIY and peer to peer sharing of knowledge. Makerbot Industries might sell you an additive printer, but what you do with it is produce, and everything is out in the open so you can make your own repairs, source your own supplies, etc.

The Internet had the promise of expanding P2P and Seed culture, but has become more about consumption (a theme that proved prevalent at HOPE9). Home manufacturing similarly pushes us toward a producer culture; the change this may bring is not all so rosy.

Four years ago "You wouldn't pirate a car would you?" was an absurd parody of itself; now replicating an army of RPG miniatures isn't really stretching the imagination. This poses a possible threat to the revenue models of some rather profitable businesses; and thus the threat that we may see lobbying from those entities similar to what the RIAA/MPAA have done for the last decade.

The pace of innovation in open hardware might be threatened by patents in the way they have affected software: as the twenty year term seems infinite in the software world, the pace of development in the hardware world seems to have caught up. McKon especially feared a patent arms-race like we've seen with Smartphone companies leading to crippling lawsuits for everyone. Luckily, McKon reports that this certainly has not begun, but notes that a few "hey, we've got these patents and you might be violating them, thought you might want to know" letters have been received by some.

Right now Makerspaces and Maker culture are the hot thing; McKon believes that Maker culture is well on its way to the peak of inflated expectations, and that a crash is inevitable. Some funded hackerspaces may lose funding, some will disappear, device manufacturers will consolidate, etc. But, eventually things will level out to a sustainable Hackerspace population. What that level is remains to be seen, but what is known is that something is brewing.

Riskable writes "As a follow-up to my previous Slashdot story, Gate One is now out of beta. Packages can be downloaded here. There's also a live demo: press the ESC key on this page to have a terminal running lynx drop into view, Quake-style! I've also posted a video overview and the documentation can be found here. Some pertinent changes since the beta: Added the ability display images inline within terminals, key-based SSH authentication, a WebSockets authentication API (for secure embedding), dramatically improved terminal emulation, an overhauled bookmark manager, support for international keyboard layouts, and a web-based log viewer that lets you export logs to self-contained HTML playback files."
