Hi -- I'm Andy Rothfusz. I've made a career out of helping other engineers get the most out of my company's products, whatever that product is, from graphics chips to cell phones, from NLP to streaming video, PaaS and Linux Containers.

ARothfusz··on House-elf Bias
Thanks for the interesting lens! It made me read the scheduling article (https://news.ycombinator.com/item?id=8177262) in a new way.
ARothfusz··on Scheduling Technology Leaves Low-Income Parents With Hours of Chaos
This article and the one on "House Elf Bias" (https://news.ycombinator.com/item?id=8177292) reinforce each other. What magic had to happen to create that 40 hour schedule? What does the world look like to Gavin, the 4 year old son in the scheduling story?
ARothfusz··on CircleCI launches Docker support
Congratulations on the Docker-in-Dockerification!
ARothfusz··on The Lowdown on Lidar
Well, he fought with half science: he came up with a set of testable hypotheses, but didn't actually run any of the tests. I guess that's as scientific as cosmology :-)
ARothfusz··on NOAA View Data Exploration Tool
Wow! That's an amazing set of data! But as I watched the introductory video, a phrase caught my ear: "you can display this on NOAA Science on a Sphere or other spherical displays". Whaaaa? Spherical displays? And that was a throwaway phrase, like everyone has them. Here's what she was talking about, probably worthy of its own HN post: http://sos.noaa.gov/What_is_SOS/index.html
ARothfusz··on Atlantropa
Is there an explanation for how adding these dams lowers water levels?
ARothfusz··on Popcorntime is leaving GitHub
I look forward to their next DMCA notice to GitHub, to take down their takedown notice, since it contains copyrighted images.

I don't understand how playing an unlicensed torrent makes the source code to the software infringe on the DMCA. Shouldn't they also send pictures of the computers which are running Popcorntime to the computer manufacturers and tell them that they are infringing for enabling Popcorntime? And pictures of the running software to GNU for creating the compilers that compiled the code?

ARothfusz··on The history of the modern graphics processor
Very nice. Though I wonder why the author thought we (3Dfx) were "strongly against OpenGL"? One of our founders, Gary Tarolli, worked on Iris GL[1][2]. We weren't against it, but our pixel pipeline was in the wrong order to implement it precisely. Plus there was the GL tradition of handling things in software that your hardware didn't implement, and we hated the "slow path". Ok, maybe we were against it a bit :-) Coming back to me now.

ARothfusz··on Innovation: The Government Was Crucial After All
Presumably they do: a US patent only protects you if you are selling something in the US. Assuming that sale shows up somewhere as someone's profit, there would be an income tax from that.
ARothfusz··on After seven years, exactly one person gets off the government no-fly list
Wow, that's recursive -- downvoting (and thereby censoring) a comment satirizing censorship and redaction. I'm ok with that, since my comment could have been more explicit: did anyone else think it was weird that the thing the judge ordered the government to tell Dr. Ibrahim has been redacted? http://cdn.arstechnica.net/wp-content/uploads/2014/03/Screen...
ARothfusz··on After seven years, exactly one person gets off the government no-fly list
I firmly believe more [XXXXXXXXXXXXXXXXXXXXXXXXX] or else we're all [XXXXXXXXXXXXXXXX]!
ARothfusz··on EU has secret plan for police to 'remote stop' cars
Since anyone planning to use their car to get away from the police would disable this device/software, only honest folks would have it enabled. So the only sure way for law enforcement to use it would be to disable the cars of innocent people to act as roadblocks in front of the pursued. And, of course, there would be an incentive for the pursued to figure out how to disable cars behind them. Doesn't seem like a game we should play. I mean, at least in my dystopian imagination.
ARothfusz··on Your Docker image might be broken without you knowing it
That's not "unfortunate" -- it is by design. You use containers to minimize dependencies on the host.
ARothfusz··on Is Your TV Watching You?
I think it is kind of funny that Samsung makes these smart TVs that watch and listen to you all the time, but if you visit their campus in Seoul they put little stickers over all the camera ports on your phones and laptops, over your USB ports, and you're not allowed to bring in USB sticks at all.

ARothfusz··on Hemingway makes your writing bold and clear
Seems like a good tool to help with documentation, where long complex sentences can lead readers astray, and passive voice hides important information.
ARothfusz··on Docker 0.8: Quality, new builder features, btrfs, OSX support
You should be able to install the same iso into a VMware image. You'll need to expose the networking ports, but the information should be in the boot2docker script.
ARothfusz··on Asusgate: A story about thousands of crimeless victims
Someone needs to make a Rocket Surgeon t-shirt.
ARothfusz··on Algae to crude oil: Million-year natural process takes minutes in the lab
I don't understand the introduction: "0:15 as part of an effort to reduce use of traditional fuels like oil 0:19 which contribute to climate change"

How would using algae as a source of oil not contribute to climate change? You'd still burn it in all the old familiar ways.

ARothfusz··on A Battery Breakthrough that Proved Too Good to Be True
Imagine that it had worked. And imagine that the allegations were true: they had stolen the cathode from one company and purchased a sample of an anode from another, and that, together, they consistently stored 400 Wh/kg. Would all the intellectual property rights have stopped production anyway? Or are there circumstances when one or more governments would waive the IP rights and say "the world needs this technology to save itself from air pollution -- just make it and we'll sort out payments later"?
ARothfusz··on Show HN: Instantly run commands in the cloud using Docker
very cool! But I think the globally unique app names will feel inconvenient as you get more users. You could silently add the Orchard user id to give it a namespace.
ARothfusz··on Dotcloud becoming Docker
This link does a more in-depth explanation: http://www.docker.io/the_whole_story/#Background

In general, Docker encapsulates and runs your processes and file systems in an exactly repeatable way, and in a format that you can replicate across a wide variety of machines.

ARothfusz··on Dotcloud becoming Docker
There's no need to make a hasty decision -- we haven't changed the platform in any way or lowered our support efforts. If you've found that you can count on the dotCloud PaaS for your business (and thank you for that!), then nothing changed today. We're still here for you.

If you feel like you want to get ready for running on another platform, or using Docker as it matures, then I'd suggest the first step would be to move your databases to a neutral third party provider. With that in place, you can still run your code on the dotCloud PaaS, or anywhere else. As Docker and the ecosystem around it mature, there will be many more options.

I work for Docker Inc on the dotCloud PaaS and manage the support. If you have more private questions, you can reach us at support@dotcloud.com

ARothfusz··on U.S. spy agencies face big layoffs in government shutdown
Well, that explains today's 'Show HN: "Who is hiring"'
ARothfusz··on Nokia was developing an Android phone before the Microsoft purchase
And, of course, there's nothing to stop Microsoft from releasing an Android phone.
ARothfusz··on Hackathons don't win you customers
The only worthwhile hackathons I've ever seen or participated in were related to the release of a new API, one that none of the participants had any access to before release. This arrangement benefits both the hackathon attendees and the sponsor: attendees know that they're starting from a level playing field, that if there is a competitive angle to the hackathon, then everyone will be judged on how well they use the new API in their software and not on what they wrote before they showed up. For the sponsors, it is a trial by fire, testing their API architecture, backend, documentation, and usefulness.

I completely agree that the optimal result for an engineering-driven hackathon is a long list of bugs and a couple of surprisingly awesome demos. But I would add a room full of excited-about-pioneering developers, and a battle-tested developer support team.

ARothfusz··on Grasshopper 100m Lateral Divert Test
Holy crap. Suddenly I feel like it's the 21st Century.
ARothfusz··on Xerox responds to the recent character substitution issue
Is this a real response? It is bylined as "Guest Blogger" and is not in an official-looking blog.

ARothfusz··on The new sandbox: open-source and self-hosted
We can convert apps (including staging servers) to Live pretty quickly, usually the same business day. Or you can create a Live app yourself and re-push the code there, still talking to your staging database (giving you more time to copy the data on that database to the new application).
