  1. What about rocket propelled grenades? on US Military Told To Move From 'Expendable' To 'Reusable' Rockets (arstechnica.com) · · Score: 1

    RPGs are single use rockets. What?? Make them reusable so the enemy doesn't need to pay the full cost of launching them back? How PC of them.

  2. Re:Whatever happened to step changes? on Nvidia, Western Digital Turn to Open Source RISC-V Processors (ieee.org) · · Score: 1

    I think the old Macs were like that and even though they ran at 1/1000th the speed, they booted 100 times faster.

  3. Re: so what exactly is being streamed? on Microsoft's Next-Gen Xbox Will Focus On 'XCloud' Game Streaming (theverge.com) · · Score: 1

    More of the 1% trying to further establish their serfdom's. There is more money in renting than selling, especially if they can lock you in.

  4. Not all patents. Sometimes they're the only thing keeping brilliant minds like Nikola Tesla's from living in destitution with no means to further explore technology. Certain software that is not obvious to programmers of the day (traveling salesman solution for example) is probably worth a patent as well.

  5. subsidized prepaid phones on Frequent Smart Phone, Internet Use Linked To Symptoms Of ADHD in Teens (npr.org) · · Score: 1

    For ~$20 its about 2-3 generations behind, for ~$50 its about 1-2 generations behind. Some of them may have smaller screens to save on cost, but it also fits smaller hands better. The screens aren't as durable either, but better to learn how to take care of a phone on a cheap burner than an iPhone that costs 50 times as much. Alternatively, you can upgrade your phone and give them your old one. Learning on a limited device teaches them how to conserve resources better in a similar way to gen-X coders learning to program on cheap Packard Bell's made more capable programmers. Don't fall into the trap of giving kids everything they want.

    $20 android phone + google voice + hangouts dialer = phone with free service anywhere there is WiFi.

  7. Tragedy of the commons. on With So Many Eyeballs, Is Open Source Security Better? (esecurityplanet.com) · · Score: 1

    Yes, the bugs can be shallow, but the eyes have to actually look at the code. Unfortunately everyone assumes another has done it or will. Guess what, they haven't and won't.
    Do you see anyone debloating the kernel? I looked into it once (video drivers primarily), but there was so much code duplication scattered in so many places that it would have required more time than I had and more importantly lots of interaction with the lkml...
    Maybe with a GSOC project or some other sponsorship, but until then there will be very few eyes on the prize.

  8. Great a solid state Stirling engine alternative. on High-Power Thermoelectric Generator Utilizes Thermal Difference of Only 5C (newelectronics.co.uk) · · Score: 1

    Way less efficient than a low temperature differential Stirling, but plenty of room for improvement. It could also use the coldness of space as the heat sink using some new tech... can't find the link at the moment, but there was a TED talk on it.

    Those patents are long dead and SSE(2) that make up the basis of X86_64 will be by the time the chips get to market if they aren't already.

  10. Re: Triumvirate?! on China Begins Production Of x86 Processors Based On AMD's IP (tomshardware.com) · · Score: 1

    As for x86, there is also DMP. No x86_64 from them though. I kinda liked the surfboard computer that had everything in a standard keyboard and the gecko edubook that ran on regular AA batteries (rechargeable ones typically). They're kinda slow, but that's on an older process. I've often wondered how efficient/fast an old school 2/3/4-86 could be if it were redesigned for current fab processes. I think I still have a Debian Woody CD around somewhere.

  11. They likely chose 512 so that they didn't need to make all the necessary compiler improvements from scratch.

  12. Welcome to the age of digital serfdom. on 'Why You Should Not Use Google Cloud' (medium.com) · · Score: 1

    Sharecroppers, company stores, vassals, etc... all have digital counterparts these days. Instead of a single entity though, it is spread out among several corporate entities and perpetuated by all levels of government. It's only going to get worse unless/until the people revolt. Problem is most of them don't even realize it. Quite clever way of creating highly productive slaves who think they are free.

  13. Here's a free analog alternative on Engineers Develop Electric Car Battery That Can Heat Itself During Winter (popularmechanics.com) · · Score: 1, Insightful

    Use thermal expansion coefficient to allow terminals to touch when cold (when it heats up sufficiently the terminals will disconnect) . In case this isn't obvious I am placing it in the public domain.

    Only if the one who discovered it was vegan and discovered it year's ago. It is a pretty advantageous symbiotic relationship for the tick though if all the infected omnivorous predators stop killing off potential hosts.

  17. Damn MS and Apple on 'Snapdragon 1000' Chip May Be Designed For PCs From the Ground Up (engadget.com) · · Score: 3, Interesting

    PC used to mean Personal Computer. That could be any architecture. Somewhere along the line (possibly before those Mac vs PC commercials) PC came to be assumed Windows on Intel (most Luddites don't even know about AMD, much less VIA and other x86 competitors) A PC could be SuperH architecture running FreeBSD. IIRC, there was a company that tried to trademark "PC LAPTOPS", but PC had become so associated with Windows and Intel that the examiners sited the use of PC as an adjective.

  19. Re:Globalization is great on Supreme Court Backs Award of Overseas Patent Damages (reuters.com) · · Score: 2

    Many sources say they went to Hollywood to escape Edison's patent trolls. Though that seems to need some clarification.

  20. If you read the patent instead of just looking at the pictures, he explains that. Not a steam turbine, but a gas turbine using Tesla's turbines that can operate at much higher speeds than traditional gas turbine engines. The History Channel made the same assumptions based on the drawings... they also assume that he didn't account for the gyroscopic torque (which he does in the text). The real invention is a different type of turbofan that could produce more thrust in a smaller, lighter package. The heliplane just happened to be the novel niche where he envisioned its usage. I'd have to check, but I am pretty sure it predates variable pitch props, which would make it even more plausible.

  21. Its beta decay, thus none of the "radiation" escapes a thin film wrapper. So no, it makes total sense.

  22. Re:Just imagine... on Russian Scientists Upgrade Nuclear Battery Design To Increase Power Output (sciencealert.com) · · Score: 3, Interesting

    That could have been the case if it used NiFe batteries. Ironically, that is another technology invented by a European and rebranded with Thomas Edison's name. Only NiFe batteries are secondary cells, not primary and definitely not nuclear. With Nikola Tesla's history with Edison it would have been too ironic... may as well get the backing of J.P. Morgan-Chase for a little icing on the cake and put one of those Marconi radio receivers in it and Apple's wireless charging system.

    Perhaps when Elon Musk bases the flying car off of Tesla's vertical takeoff and landing heliplane, we can see more or his inventions that no-one knows about. Strange that for his last 20 years no patents appear in the public records.

  23. Lake Nyos lessons on Invisible Scum on Sea Cuts CO2 Exchange With Air 'By Up To 50%' (theguardian.com) · · Score: 3, Informative

    Deep water stores more CO2 due to its higher pressure, but natural events can cause overturn. I'm not sure any climate models account for that. A major storm, earthquake or landslide could break up the layer while bringing the high concentrations of CO2 (and other gases) to the surface to effervesce. This could explains some of the unexplained coastal die offs. The events at Lake Nyos killed hundreds of people.

    If you haven't detected the pattern already, when the initial leader gets surpassed, they dont try to innovate and compete, they fall back on patent protections. I would argue that none of it passes the obvious test - I wrote my own extensible version a decade ago by piping poketsphinx_continuous through a bash read line loop... though I didn't keep any data (except the current line) unless you asked it to dictate.

  25. Re: It will cost a lot more than they expect on Massachusetts Gains Foothold in Offshore Wind Power, Long Ignored in US (nytimes.com) · · Score: 2

    The machine room on a large ship requires a lot of maintenance and has a crew to do it. I spent almost as much time chipping and painting as I did operating the reactor. Good on you though, you'll have plenty of work for years to come. After a couple generations, they will get the engineering right, but your description differs very little from land base windmills. After the 1st generation they probably discovered that the cooling coils should be Monel, like the use in heat exchangers on ships, but were probably copper or aluminum because they are better heat conductors and cheaper. I bet plenty of copper bus bars corroded in the first gen too. Keep up the progress though. The only thing worse than failing is not ever trying.
