Pwnguinz··on Show HN: Skyrim – Open-source Large Weather Model (LWM) Zoo
What's the granularity of the prediction (I'm not sure if that's the correct word? I'm not a meteorologist)? Region level (100s km)? City level (a few 10s of kms)? Block level (a few kms)?

When you say it's on par with global weather models, how is "weather prediction accuracy" measured?

Cool, none-the-less!

Pwnguinz··on Show HN: Glue4 is a Redux extension that handles your back end concerns
Thanks, and I appreciate the questions:

1. Glue4 is not a query storage nor technically a "real-time" database, so the trade offs are different (you don't have to use a proprietary SDK to query your data, everything is in your Redux store as a JSON object). As well, this is a plug and play Redux add-on, you don't need to change anything about your current application.

2. It's represented as JSON-serializable data. The storage abstraction is an implementation detail. Currently it's literally serialised to disk, but we can just as well store it in DynamoDB, Mongo, PostgreSQL's JSONB column, etc. We will eventually support complex data (like images, videos, BigInt, etc) and transparently serialise/deserialise them for you and persist them for you in the appropriate storage (i.e. if you add an image to your Redux state as a user avatar, we will upload it to a blob storage and send it through a CDN for future fetches, all transparent to you as the developer).

2.a.: Yes, for the current version that is the case. Local persistence (offline first) is definitely something we want to support down the road!

3. A high level roadmap is actually available on our website if you scroll down :).

Let me know if there's anything else :D!

Pwnguinz··on Twitter Contest Winning as a Service
You are referring to Pokémon (notice the o where there was an a previously). And you are correct, the é has an accent on it (though I've always wondered why--Pokemon is an abbreviation for "Pocket Monsters", and neither of the e's either word contains have an accented e!).
Pwnguinz··on Concatenative Editing
What's the problem? One is lowercase and the other clearly upper case.

Much like in vim: "f" searches _forward_ while "F" searches _backwards_. Perfectly valid. I see no implementation hurdles here.

Pwnguinz··on Stopping HIV with an artificial protein
> were HIV to mutate away from being able to bind to those chunks it too would become less virulent when attacking the real proteins.

Forgive my ignorance, but are there any indicators to predict whether a virus will evolve one way or another?

What I mean is, once it comes in contact with these mimic proteins, instead of mutating away from binding to these proteins, can it not mutate in such a way that it increases its virility so that it will bind onto more proteins in an effort to combat "false positives"? So it'll become even more virulent in individuals that have not received this treatment, and maintain its current virility in individuals receiving such treatments?

Pwnguinz··on You can use vi mode editing in any program that uses readline
What happens if you don't set keymap "gg", "G", etc? Would they not work, or...? (Currently not on a *nix machine to be able to test it out, or else I wouldn't ask such a simple question :P)
Pwnguinz··on DNSimple DDOS Attack
How were you able to find out what IP was cached for a particular domain?
Pwnguinz··on Hal Finney being cryopreserved now
The abstract makes no mention of -130°C, but digging into the actual paper (can be read here: www.21cm.com/pdfs/cryopreservation_advances.pdf), it does mention: "Fig. 13. Confinement of ice formation to the pelvis of a rabbit kidney that was perfused with M22 at 22°C for 25min, bisected, and allowed to passively cool in air in a CryoStar freezer at about 130°C... The vast majority of the kidney appears to have vitrified and is indistinguishable from the appearance of the kidney prior to cooling." (Emphasis mine)
Pwnguinz··on The Guide to Not Buying a 3D Printer
If you just need occasional printing done locally (so you can pick it up, inspect it, or ask questions in person), you can use this site to find a shop doing 3D printing with this website: http://www.3dhubs.com/

Might be less hassle than renting an actual machine.

Pwnguinz··on DeepFace: Closing the Gap to Human-Level Performance in Face Verification
"Leverage" doesn't always equate to profit (or even revenue). The "goal" of the NSA is not profit, but mass surveillance. Whereas surveillance historically has been centralized, with the onslaught of mobile devices, we now have prevalent distributed surveillance (and perhaps more so than surveillance).

All the data everyone is feeding into FB/G+/Twitter/etc about their friends and acquaintances could not have been collected on such a mass scale by the NSA alone.

If you're a privacy conscious individual, there's definitely reasons to be fearful of this approach to surveillance by any governmental intelligence agency.

Pwnguinz··on Inside DuckDuckGo, Google's Tiniest, Fiercest Competitor
Behind the scenes, DDG uses Yandex and Bing to power its search results. It also does its own crawling (however, I'm not sure to what extent).

Their algorithm isn't necessarily better, but if you were to just give it a try, you'll notice their 'Instant Answers' section at the top of a search that usually gets you exactly what you want without having to click on a single result (much like how certain search queries on Google will return you an instant answer).

Pwnguinz··on I got hired at a Bangladesh sweatshop. Meet my 9-year-old boss [video]
> When a US factory burns down and kills all the employees inside because they'd been locked in during their 15 hour shift.

I give you the Triangle Shirtwaist Factory fire in New York City, killing 146 garment workers. Same general gist, even: doors were locked by management from the outside "to prevent pilferage and unauthorized breaks".

Pwnguinz··on Perceived Performance: Ways to Make Your Mobile Site Feel Like a Native App
"Not really, no. Anything under about 25-50 will feel instantaneous. Between 50-100 you're looking at something that doesn't consciously register as 'slow', yet feels vaguely sluggish - especially when it comes to responding to taps on a screen."

Not according to empirical findings: http://www.nngroup.com/articles/response-times-3-important-l...

Funny that you mention BB10; I used to work at RIM (a handful of years ago), and developer relations were disseminating documents that said application developers should make apps respond in less than 150ms to give the illusion of instantaneousness.

Mind you, I'm not saying YOU can't perceive the difference between 100ms and 25ms, but that in the general populace, the limit of perception is around 100ms.

Pwnguinz··on How Nancy Pelosi Saved the NSA Surveillance Program
It's merely a JS based modal box. You can use your web browser's devtool/inspector to delete the two divs, one for the black transparent overlay, and one for the sign-up modal.

Pwnguinz··on Elon Musk's mission to Mars
I think the point is that Jobs himself only ran one company at a time, though he had many successes. Elon is doing at least three things at once (Chairman of the board of Solar City. CEO of both Tesla and SpaceX), and the Hyperloops looks to be a fourth.
Pwnguinz··on Anonymous hacks FEMA
False dichotomy. China is a de facto dictatorship (and a de juris Republic), however their citizens can still surf the internet and type out things (censored, for sure, but a far cry from 'shut off').

Do you really want society to collapse to the point of Syria or Lybia before you want the citizenry to stand up for themselves? Or is everyone just a tin-foil hatter until secret police starts wisking people away?

Pwnguinz··on Yahoo shutting down AltaVista and other services
Apparently one of the features is that you can use it to easily scrape other websites! The only overhead would be one network API call (the fetching and parsing of information all happens on the Yahoo! servers and it returns the sanitized output to your application). I might give it a spin sometimes :).
Pwnguinz··on Battery Swap [video]
Elon explains that it was using the same machine as in the manufacturing factory.
Pwnguinz··on Battery Swap [video]
Not just that, most people will most likely just charge at home and use battery swaps as an absolute last resort or when they're on a long road trip. I'm sure the cost associated with a battery swap is not "cheap" (i.e. diffing your battery capacity versus the battery capacity of the new battery and multiplying that by the total cost of the new battery. You weren't thinking you can just roll into any 'ol battery depot and swap out your 5 year old Model S battery with a brand spankin' new one, right ;)?)
Pwnguinz··on NY auto dealers trying to shut down Tesla Motors in NY
Huh? "Corporation" is merely a registration status. A small-time business/startup may very well be incorporated as a Delaware C Corp.

What do you mean by 'difference the license plate numbers'?
Pwnguinz··on Free Official MSIE VM's for Linux and Mac
IE10's dev tools emulation is not perfect, and has its own set of quirks. Especially as it relates to the JS runtime[1].

Sure, that's the "technically correct, but practically worthless" answer. Trigger hyper-inflation and then what? It surely won't be "business as usual" afterwards.
Pwnguinz··on Breaker 101: An intensive online web security course
Not the target of a teacher that is asking for this price. There are plenty of teachers out there that can, presumably, teach the same material just as well for probably less cost to the student, however it's not the OP's job to find those alternative sources for you.

Fascinating, where do you find these bonds and/or info on them? Do you work for a financial institution that have internal proprietary access to such information, or is this publicly searchable?
