Curious how this is being pulled off. How can devices connect without any 3g, wifi or bluetooth?
Yeah I think we just disagree.

- An exchange is definitely a huge opportunity and a valid direction regardless of whether it'd be useful to you. and one that would make wall street more interested in Bitcoin which would push it mainstream.

- I feel this "vault" stuff won't do much to convince people it's secure. who knows whether the security is even different? just more terminology to learn = greater friction. keep it simple.

- does their button even support mobile?

you have a valid point here but isn't the whole purpose to get the product in front of people's eyes as soon as possible to validate?
I am not surprised by your results. However, the system is more robust than your experience would indicate.

OpenCyc is a subset of ResearchCyc, which itself is a subset of (Full)Cyc. OpenCyc is primarily used for mapping between ontologies. It contains 239k concepts from ResearchCyc, but only the basic rules for definitional relationships between them. These relationships include part/whole, disjointness, etc.

You mention DBPedia as being superior for your purpose, but I would counter that the two are complementary. There is a mapping between DBPedia and OpenCyc within the Linking Open Data cloud. In fact, it was one of the first ontologies contributed to the W3C's LOD initiative[1][2].

The concepts in OpenCyc are rigorously organized from most general (e.g. Thing) to more specific (e.g. board game). Each concept may have specific instances (e.g. Yahtzee, Trivial Pursuit, Scrabble, etc.) These primitives all live within a custom Lisp, where they may be reasoned over. DBPedia's structure arises naturally from user activity. It is organized primarily by Wikipedia's category system and includes individual pages.

Unlike Wikipedia, the Cyc project does not aim to contain every instance of a concept. The relationships between concepts are what matter. Once one knows that something belongs to a given Cyc concept, one can leverage the system's knowledge to reason about it.

OpenCyc's reasoning capability is limited by a lack of assertions (facts and rules) -- ResearchCyc's is not. ResearchCyc contains over 5 million assertions not present in OpenCyc. (Things like: water is wet, a dog is a mammal, mammals have hair, etc.) It also contains Natural Language tools not present in OpenCyc: parsers, taggers and more. With these tools, one can go from natural language to a formal logic representation. Or, given a formal representation generate natural language. These capabilities exist today in real world applications[3][4].

- Expand the capabilities offered by the unsafe package

- Offer more control over the GC behavior

- Add a kind of untraced pointer or a GC API for allocating them
It's pretty easy to figure out looking at her LinkedIn and story. She was on F1/J1 visa to study English for two years (2009-2010) and then attended Foothill College (2010-2012). I am surprised that they allowed her to go to community college when she already had B.A. for University of Bogota. I was told that this loophole was closed. I have several friends who used ESL courses and community colleges to maintain legal status in US. Usually you pay around 1k/month in tuition and it gives you legal status. Sometimes attendance is required and sometimes attendance is more or less optional. She said in story that she had four different visas - probably mix of F1/J1/B1 visas.

The only work visa she can reasonably qualify for is H1B and I am not sure what decision she is waiting for - FY2014 started 10 month ago and FY2015 starts only in October. If you look at her LinkedIn she clearly worked while in US so she broke visa rules even if she was not paid (you could not even legally volunteer while on F1/J1/B1 visa if somebody can reasonably pay for that work to US citizen). CBP officers have internet and they can certainly search FB/LinkedIn too. Unless she is wealthy enough to live 7 years in US without any income, she clearly made money somewhere.

It's dangerous to built your life on those types of visas if you do not have clear end game (marriage to USC or work visa). She played the system and she lost. I am immigrant myself and I was very careful not to have long term plans in US before I got green card because I understood that I may have to move back to my home country at any moment with only 30 day notice.

Are you just making Zigbee hardware API calls - or custom firmware? Are you a part of the Zigbee aliance? How did that effect development?

As for claims of range, I'm impressed. Since 2010 onward my startup has built various configurations of Zigbee networks (some >100sq km) - but only saw a max reliable range of 4km (rooftop of 4th floor, clear line of sight, 1W)...which prompted experiments in moving things down to 433Mhz. Just curious what magic is going on....

Should we be labeling children (or anyone) as "binge drinkers", and taking action, based on probabilities?

I know the label is "likely binge drinker", but that's not much better and few will bother with the fine distinction. Will school authorities be biased against them, consciously or not (will they make the team? be trusted by the teacher? promoted to fast track?). Will they get jobs? Will law enforcement be biased against them? Their own parents? How will their classmates react? Will they have a social life on Saturday night? Will you let them date your son/daughter?

Worse, the object of the label, especially without a very strong sense of him/herself, certainly will not benefit from the label of, effectively, "genetically determined loser".

No, that was Danny Hillis. Freebase was purchased by Google and became the core of what is now known as the Google Knowledge Graph.

My thinking on vitamins is governed by several principles:

The data is inconclusive

I take a multivitamin and sometimes macro-dose on C and E.

I think you're focusing too much on technical details. An email sitting on the server unread is effectively still undelivered. GS wants to cancel delivery. I see that as fair and not intrusive.

It might not have even been an active account.

Why in the world should that be assumed instead of checked?

Reluctant seems perfectly cromulent here. Pretty much any definition includes 'unwilling', and the word itself in its original form contains the image of struggling against something.

When will you all be posting more information about the hardware module? I'm curious about the specifics of the hardware, (basically datasheet stuff for those of us actually designing hardware):

* supported voltages: 5V, 3v3, 1v8, ...?

* module communication: SPI, i2c, TTL serial, etc.

* module programming: sounds like there is a way to load my key on to the module, will that be done through the attached platform? Or will you need a proprietary programmer?

* footprint for the module: not only dimensions, but keep aways (antenna, etc), orientation, etc. And from the website photo looks like there are no mounting holes on the pcb, and those are especially handy when prototyping

* external antenna: I realize this throws a monkey wrench in the FCC cert, but there are going to be applications where an external antenna is going to be a necessity. Any plans for an external antenna module?

* EN pin: the Iq on many of these radios make it necessary to completely disable them for extreme power savings. Be curious how quickly the radio module can cold boot and establish a link with a base station.

As for the network, no mention of communications with the devices, strictly one way? No ability to push updates to sensors in the field?

I'm missing a couple of others, but I'm too braindead to think of them at this hour.

This looks like it could be a huge time saver for those looking to build out sensor networks, I hope for your success!

> Those density figures are misleading ... The populated parts of Tokyo and Seoul are of similar density (as is Mexico City)

I'm not disputing that. The difference is that the "populated parts" of Seoul comprise the entire habitable area of the city, which is what makes public transit so affordable even for those who live in the outskirts.

There is no low-density "sprawl" in or around Seoul. It's all high-rise apartments and condos until you abruptly hit some sort of obstacle (like a mountain). It makes little difference which counties and districts you pick. Of the 25 wards that make up Seoul, the one with the lowest population density has 25K per sq mi. The highest has 74K. So the peak is lower than NYC, but the standard deviation is much lower as well. In other words, there's less diversity of living arrangements.

A random residential area in the outskirts of Seoul looks like [1].

In an actual legal case you'd also be liable for damages. I agree it's unhelpful of Universal to just yank the material without providing feedback on what, exactly, infringed their copyright, but the fact remains that the responsibility for copyright clearance lies with the person who wants to copy the work, not the rightsholder.

I agree it's distasteful, but given that Greg seems to be well-established professionally there's no way he doesn't know this. It's rather absurd to see him accusing SoundCloud of 'stealing' his subscription fee - ie complaining about the loss of his property interest in his SC account - while at the same time thinking he can help himself to all the raw material, ie other people's published music.

Yes, it's unfair that broadcast radio stations get all their music for free by default, while internet DJs don't, legally. They get that because they banded together and negotiated for those rights. That's the solution: collaborate with other internet radio DJs and draft a blanket license agreement for noncommercial reproduction, then shop it to labels.

Pete Hunt addresses this specifically in this React talk starting at 3 minutes:

https://www.youtube.com/watch?v=DgVS-zXgMTk#t=182

Basically, the idea is that most JS templating solutions separate technologies (HTML , JS, templating languages), but don't actually separate concerns, because the concern is simply generating and updating DOM regardless of how many technologies you use.

Most JavaScript frameworks or libraries that handling generating and updating DOM, like Ember's two-way binding with Handlebars and Angular's dirty checking with directives, don't really separate markup from logic. They just invent a new language to mix with your HTML, and that new language is deliberately made extremely weak.

Our current causal models of how nutrients behave in our bodies are woefully incomplete. Many of the substances referred to under the term "Vitamin X" come in many forms that do different things. It is unsurprising that an isolated compound doesn't help much. MealSquares address exactly this issue. We know we're supposed to eat a variety of whole foods but we don't. So we put a whole bunch of nutrient dense foods in a convenient package. Bioavailability is much much better than supplements.
The description of the problem is in the Youtube video. I was trying to listen to a song at SoundCloud (or, perhaps more likely, a malicious site that imitates SoundCloud; I did not check the URL too closely), and as soon as I hit the "Play" button, my laptop's screen entered a "dead pixel test pattern" where it flashes white, black, red, green, blue in succession. It now does this constantly, even at bootup - sometimes you'll get lucky and see the startup screen, but more often it starts that test pattern from the very moment you power on the machine. Additionally, it is very clearly doing something behind that pattern - one time when I was able to log in to Windows before the test pattern started, I noticed that a) Dropbox had been disabled, and b) the machine was uploading a huge amount of data - 1GB in the perhaps five minutes I was able to use the machine. (Naturally, once I saw that upload happening, I disconnected from the network. Unfortunately I did not have a chance to find out where it was sending data and/or what data was being sent before the test pattern activated again).

Is this a known malware, or something new? Has this happened to anyone else; does anyone know anything about it?

Thanks in advance, HN.

That should create opportunity for automated trading. Identify large orders and place small orders a de minimis amount ahead of them when the bid-offer spread is sufficiently large. If someone trades with your bid (offer), try to be the best offer (bid) to exit and make the spread. If the large order behind you starts trading, trade with it to lose 0.01.

I've traded these markets by hand before using relative value signals from other exchanges (e.g. buy on bitstamp if btc-e moves up and bitstamp hasn't yet). You can't really do pure arbitrages since it takes so long to move money around but if you can identify which market leads you can use that as a starting point for coming up with a fair price to trade around. I made money easily but gave up on trying to automate it since the volume is so low, bid-offer spreads are often tighter than 2*trading fees, you can't short-sell easily/cheaply, exchanges seem incompetent or downright crooked, laughably bad APIs, etc.

These markets are wildly inefficient though. For a home day-trader or hobbyist there's easy money to be made. It's absurd how slowly price discovery trickles from one market to another. Most modern markets don't even get mispriced by a penny for more than a few microseconds, but there are nickels, dimes, quarters and even dollars of mispricing to capture in BTC/USD markets clicking on the screen.

You could probably dominate with an algo, but how much can you really make in a market that trades 10s of millions in notional value a day? There are also way too many exceptional conditions to let it run even semi-unattended since the exchanges are too immature. Anyone who's capable of doing it can make more doing the same thing on a real market.

ETA: Exchanges in this space are really, really bad. Some don't even know about rounding errors when using floating point for prices. Or would you trust trading on a market that can't even match trades as an atomic event? http://www.reddit.com/r/Bitcoin/comments/1r4d6t/bitstamps_st...
