GeorgeHahn··on How Nicaraguan Villagers Built Their Own Electric Grid
I've created a userstyle that makes IEEE Spectrum palatable. If you use Stylish, check it out: https://userstyles.org/styles/112927/ieee-spectrum-suckless
GeorgeHahn··on Delphi's self-driving car
They didn't do the drive yet, this is just a piece of fluff to fill the time between their initial announcement and the drive (which will start next week).
GeorgeHahn··on Transducers are coming (2014)
Post is about Clojure
GeorgeHahn··on Intel forges ahead to 10nm, will move away from silicon at 7nm
Lots of opportunities throughout the rest of the stack too - from novel architectures to on-chip programmable logic, the end of Moore's law puts more pressure on some really interesting innovation.

eg Rainbow[0], BORPH[1], Mill architecture[2]

GeorgeHahn··on The Emterpreter: Run asm.js code before it can be parsed
Is it straightforward to reference a separate compiled library from an Emscripten binary?

Seems that caching commonly shared dependencies could be a good way to cut down on size and parse/compile time.

GeorgeHahn··on Calaos: Open Source Home Automation
Wiki is pretty empty. Is this built on open standards? Can it control hardware that uses MQTT and CoAP? How does it compare with OpenHAB?
GeorgeHahn··on Hard Drive Data Sets
Firefox Nightly. Oddly enough, the page loads fine on my laptop with the same browser. I'll diff my configs and see if anything interesting shows up.
GeorgeHahn··on Hard Drive Data Sets
Even though it stops folks with updated browsers from accessing your site?

GeorgeHahn··on CoreCLR is now open source

GeorgeHahn··on Turbocharged Raspberry Pi 2 unleashed
No chance.
GeorgeHahn··on Turbocharged Raspberry Pi 2 unleashed
Allwinner will give you their datasheets if you email them. Mediatek not so much (& no experience with Rockchip).
GeorgeHahn··on Google Earth Pro Now Free?
Not always true - some companies will give CV certs to OSS projects.
GeorgeHahn··on Why the Cool Kids Don't Use Erlang [video]
Do you think folks who are just getting started in the Erlang ecosystem would be better to learn Elixir before Erlang?
GeorgeHahn··on Show HN: PolyBrowser 1.0 – A new way to browse the web. What do you think?
Ctrl + click doesn't open links in new tabs. Cool idea, but this totally kills it for me.
GeorgeHahn··on Intel unveils tiny $99 MinnowBoard Max open single-board computer
I considered writing a LLVM backend for the PRUs, but put it aside while I wait to see if the rumors of a TI provided compiler pan out.
GeorgeHahn··on Open Hardware Bitcoin Miner
No BGAs, I think you might be seeing the crazy thermal via arrays under the chips (I went a little overboard, the next revision will likely have a couple less vias on each chip). The hashing ICs are QFN.

This would be a really easy board to manufacture. Low unique part count. I just need to move the decoupling cap vias out of pad and it'll be ready.

GeorgeHahn··on Open Hardware Bitcoin Miner
I agree. The via in pads was done more as an experiment to see what would happen - I'd never tried it before. They lower the inductance on the ground path, but it's not a huge deal. They'll be relocated in a future iteration. The QFNs have more vias than they need.
GeorgeHahn··on How we can fix Intro to Engineering courses
I'm referring to generic Introduction to Engineering courses. The ones that focus on topics around engineering; things like presenting, interviewing, etc.

(Classes that use books like Studying Engineering: A Roadmap to a Rewarding Career - ISBN 0964696924)

GeorgeHahn··on Ask HN: Any self hosting blook software?
Imperfect solution, but MediaWiki (http://www.mediawiki.org/) comes to mind. Wikibooks (http://www.wikibooks.org/) is using it fairly successfully.
GeorgeHahn··on Ask HN: What do you use to store your bookmarks
I use Pocket - it has extensions for desktop browsers, apps for major mobile platforms, and offline sync. Free.
