Will this work for Rails 3.2?
Great points.

Though I believe algorithmic knowledge is a lot more practical than people give it credit for. I'm not talking about crazy graph searches, or implementing A* in ASM.

Are you going to be efficiently searching strings, or reordering arrays, full time? Probably not, but you will likely come across a time where you will need to think about the consequences of your design, even in a simple crud web-app. And that stuff is important.
"How to incentivize people to become brilliant musicians"

"How to incentivize people to become world-renown artists"

"How to incentivize people to become best-selling authors"

"How to incentivize people to become Nobel laureates"

Yeah, none of those work. Why would program managers expect it to work for software developers?

On the other hand, there's probably a lot of money to be made in writing a series of books with those titles. They'd be utter garbage, but I'd bet they'd sell well.

> How do you know it doesn't rely on directional antennas in addition to the multi-phase solution?

Because:

1. The article claims it can use the existing cell tower system.

2. Cell tower antennas are simple dipoles, not directional antennas.

> If I were trying to do something like this I would ABSOLUTELY use multiple directional antennas in each base station AND phase things appropriately.

Yes, that would improve the performance, but this would make it a hard sell to cell companies who are trying to reduce the cost of their installed equipment. Also, to use directional antennas in a high-speed dynamic network, for a given beam width N, you would need 360/N directional antennas. For a beam width of 30 degrees, you would need 12 antennas where one exists now, and you would need a way to switch between antennas on each transmitted packet to multiple served devices. That would be a nightmare.

> Obviously I haven't studied the patent in detail but that does sound to me like there are multiple antennas per base station.

Yes, the basic idea requires multiple antennas whose relative phase can be adjusted. But not directional antennas.
Works great for me. There's some minimal configuration explained in the pgbouncer docs. What the pgbouncer buildpack does is just route your DATABASE_URL through the local pgbouncer.

In my python app, I switched from an sqlalchemy connection pool per process (eg per gunicorn worker) to using a Null pool everwhere. No increase in latency; far fewer connections needed.
If the wavelength at 700Mhz is 43cm, wouldn't this have to track the position of the phone to within ~5-10cm to get a benefit? Or at least relative distance between antennas.
The municipalities have no money to build, and more importantly, to maintain and continually upgrade, such networks. Heck, they can barely maintain utility systems that evolve far slower than internet connectivity: power and water. See: http://www.nytimes.com/2009/04/18/us/18water.html?_r=0. People outside of HN won't be anywhere near sufficiently eager to earmark sufficient public dollars to properly maintain such networks, not when pensions systems are underfunded and schools are putting teachers on furlough.
>I've always thought of Canada as a fairly responsive democracy.

Nope. We elect one group of corrupt assholes to run things, and then complain about them being corrupt assholes. We keep re-electing them till they do something so hugely scandalous that we elect the other group of corrupt assholes instead. And then keep re-electing them until they fuck up so badly that we switch back to electing the first group of corrupt assholes again. Our government is currently pushing for more restrictive drug laws, including for weed. They are pushing for mandatory minimum sentences for non violent crimes, and for privatized prisons. These things are almost universally opposed by Canadians. It simply doesn't matter, we re-elect them anyways.
If their fix uses random noise per api call they are again vulnerable (just take the average of the each result).

Also again reduced precision on the reported distance won't fix the issue, you can sweep the map for changes in the last digit (by changing the attackers reported position)

They must reduce the precision of the users input not the reported distances precision.

ps. the problem in here is the accuracy not the precision
I'm on TWC and would love to get off it. How happy are you with RCN?
I probably wouldn't have chosen the name "Experiment." They won't be able to trademark that, because it's descriptive.

I think Ryza was the better choice.
The "Right Way" to Build a Company
Yes and no. The degree of precision matters a lot. "between 3-4 miles away" isn't the same as "3.42123459921 miles away". In this case, the distance field was encoded in a 64 bit double - which if fully utilized is a ridiculous degree of unnecessary precision.
I have bought domains from them in the past.

I would start off by offering half (as a maximum, less if you can) and sticking to the offer. The thing to remember is that they may have acquired the domain for registration price so even $2000 will be a large profit, and they may not have another buyer for years.

If that goes nowhere, you can always go back later and pay the full price or whatever they have come down to.

IIRC, they also sell domains which they don't own, and have less leeway for negotiation on those.
Ask HN: How to create a fake identity?
The reasons are plenty, free speech, regulation ...

Is it possible to fake one's identity, so that not even the police/government is able to find out the identity.
A lot of its name games. 10 gigs of possibilities tested is actually pretty short for something like OGR-27. We're probably going to prove OGR-27 in a few weeks (or has it already been announced?) and I'm fairly certain a list of all possible rulers checked would exceed 10 gigs. Yet you can report OGR-26 in only 26 small numbers, or I guess you could draw a graphic pix using 492 pixels or whatever.

So is OGR-27 merely 27 numbers aka a 1-d pixel "graph" probably around five hundred something pixels, or is it really zillions of gigs of rulers all of which are longer than the OGR?
> You don't need a "datacenter" per se ...

Perhaps, I'm just using the language from the linked article:

"To work properly, a company backing the pCell technology would need to build out a large data center in addition to deploying the transmitters. It’s in the data center where servers constantly crunch away on the algorithms that form the unique wireless stream aimed at each device."
For a house it's 2-5%. At this Rate, it's usually better for the broker to just close the sale whether it's $400k or $500k.

This was an example in Freakanomics Vol 1 I believe.
I think it's likely that this exists mostly as a threat to keep the big ISPs from getting complacent. If internet speeds improve via themselves or the ISPs, Google wins either way as internet usage increases.

Hello all, author here. I've been working on this javascript+webGL implementation of Milkdrop2 for a few months now. I recently got automatic preset conversion working (which required translating MDs preset language to JS and HLSL to GLSL). Still finishing up wave/shapecode support but that should be coming along soon. I couldn't resist sharing a new version.

Thanks for taking a look!
Erm...how would people feel about having this as an available module for Node.js?

No reason. ;)
When they laid fiber down in KC they had each neighborhood sign up and based on how much interest each community had they would have precedence over the others.

If the cities they choose dont have an interest then what is the point?

Who said anything about white people?

interesting. Their website is a bit lacking in info. Do they offer residential service at all right now? Looks like they are just servicing larger multi-tenant buildings, I'm guessing where everyone needs to sign up to get them to come and install.

When I saw the headline, I cringed. At this point, whenever I see a Google article titled, "The future of [google product]," I assume it's an announcement that the product is being phased out. Needless to say, I'm glad that's not what's happening here, but I'm still not holding my breath that Google Fiber is going to take over the world.
Negatively. A heavy regulatory burden will raise Google's costs to enter into this business. In particular, any last-mile network that Google would build would be much less valuable to Google if the government requires Google to be "net neutral." Of course Google wants to discriminate in favor of its traffic--and why shouldn't it? It built the network!

Government enforcement of "net neutrality" is a great idea if we want to cement the role of the incumbent operators.

The original post really is criticizing a straw man. Not just because they are missing the point such as how you are saying, but their paint positive thinking as relentless and illogical lies.

Much like criticizing all liberals as being dreadlock'd pot smoking communists, or criticizing conservatives for hating everyone who isn't them and being heartless.

Using these extreme examples does nothing more than incite arguments... But I guess in this guess arguments get you links, and links get you ad revenue... perhaps it's not so surprising why this article was written.
When the reference point is Comcast one has a high probability of being applauded.
Not quite true. If you are driving (say, along I-95 on a long trip) it's true that your phone will disassociate with one tower going out of range to a new tower coming into range, and the phone switches behind the towers will transfer "ownership" (more like association), but once you (if you aren't driving, or your passenger) accept a phone call, things get a bit different.

The cell phone is answered. So, it goes from switch O (the caller) to switch A (where your cell phone is associated with). Eventually, you'll move out of range of towers for switch A, and come into range of towers for switch B. But because the phone network is circuit switched, you can't just create a circuit from O to B. No, what happens is that A forms a connection to B, so now the call is going O -> A -> B. Talk long enough, and eventually, your call may end up going O -> A -> B -> C -> D -> E -> F.

So while it's true that your call doesn't go through multiple towers, it does go through multiple switches (as long as you are talking on the cell phone, and the cell phone is moving).
Yes - rank high for Ryza vs Experiment. It's pretty bad if you aren't the first result when someone googles your company's name especially for a company relying on word of mouth.

Presumably nothing. Unless you know how to program strong AI, and even then it probably wouldn't find anything interesting. There is no definition of what "interesting" is. It could discover tons of truths like "555 + 724 = 1279" but none of those would be particularly interesting to humans.
What about the actual building wiring? It doesn't matter whether there's fiber to the building if cable has enough bandwidth to fill the copper between the cable box and the apartments.
The U.S. is ranked #8 in average broadband connection speed in Akamai's most recent State of the Internet. That puts it ahead of most of Europe: http://www.akamai.com/dl/documents/akamai_soti_q213.pdf?WT.m... (page 13). If you look at more densely populated coastal states, the U.S. looks even better. Yeah, South Korea has widespread fiber internet. More than half the country lives in the Seoul metro area. You can't compare.
Perhaps an infinite number. However, like a tree falling in the woods ... if humans (or some other intelligence) can't understand it, has anything actually been discovered? Or is it more like a computer algorithmically solving a jigsaw puzzle?

I don't understand this argument at all. You're conceding that last-mile extortion is a market failure, then turning around and saying legislating against that last-mile extortion is "imposing ideology" rather than just addressing the market failure?

When I purchase internet connectivity, I want internet connectivity. I don't want varying grades of speed depending on who I'm talking to, I just want a dumb pipe. That's what I'm paying for. How is legislating the dumbness of the pipe 'imposing ideology'? The market is allegedly $/gb/mo, let providers compete on service, price and speed. If they can't deliver those GBs for those $s, they're free to charge more to consumers. The only ideology there is capitalism. What am I missing?

Note that I said in my original post, if Netflix doesn't have good enough peering arrangements on their end, then that's their problem and nobody thinks there should be legislation guaranteeing them cheap bandwidth. But most of us think they should be able to buy bandwidth to the consumer networks, via peering, at the market rates that everyone else pays, maybe with discounts for volume.
When he says "sub-expressions", he means it in the program-code sense. Really, he's saying: why don't we try to refactor the proof?

And, since it's so large, we probably can't do it by hand. So we would need to develop techniques to do it automatically. (Or semi-automatically.)
It seems one of the biggest costs of fiber is installation; i.e. trenching. Why is it not hung from poles? It must be much cheaper and quicker, surely?

Google: How not to be a 'Glasshole'
The present cell system can locate a cell device within the same limits using time delay and phase detection of the received signal (this requires three antennas for a 2D fix). Many cell phones that claim to have GPS actually rely on the cell network to locate them, and the location method is reasonably accurate. That means the system already knows where each device is located using the same wavelength constraints required to make this idea work.

Link: http://en.wikipedia.org/wiki/Mobile_phone_tracking

Quote: "Mobile phone tracking refers to the attaining of the current position of a mobile phone, stationary or moving. Localization may occur either via multilateration of radio signals between (several) radio towers of the network and the phone, or simply via GPS."
The exact-coordinates debacle should have been a wake-up call to examine and put some thought into the data that the service sends to users. In fixing the issue, someone should have asked "should we send a ridiculously precise number, or should we perhaps send an approximation to a mile or a tenth of a mile?". In that review, they should have decided not to send the DOB as well. It wasn't a small, new service at that point.

I doubt anyone with a semblance of a conscience in their shoes could do that, except back to the benefactor, for cheaper (which would also be pretty lame)...the man turned down 6 figure offers and gave it to them because he believed in their mission. That they would go "whoops, it cost too much, gonna sell it to whoever offers me the most while we bail from our failed startup" would make the benefactor feel like total shit. I would never do that to a guy. I'd probably go work a 9-5 for a year and keep the domain for my next stab at a dream in the space.
It looks ok... much better than the hideous default KDE in my opinion. The fact that it doesn't have the functionality of even Windows NT 4.0 (after years of pruning) is the bigger problem imho.

The question then is whether there's any exploitable semantic structure in the certificate. I would guess not, but I don't have enough knowledge of the specifics of this problem and proof to be more certain. It just doesn't feel likely - any structure would emerge in the way the sub-sequences could be constructed, and lack of such structure is what makes this problem hard.

Just a guess.

You just got a new fan! thanks for this.
But what you think of when you say "insight into the problem" might be an antiquated notion. It may be that such a thing is a rough measure of (as you almost say) how much more likely you are to prove something else (or how much easier it would be) -- without computer assistance.

But the twist is that with computer-aided proofs, being well-versed in the ways of using computers to help prove things may begin to count as having insight; and Coq (or whatever) programs may come to be studied so that one may gain insight, just as human proofs are studied today.
ZenPayroll only seems to handle a part of the overall HR equation. I wonder what ZenPayroll users do for the other parts like healthcare, 401K, etc? It is not completely clear to me either how well ZenPayroll handles things like unemployment insurance and workers compensation. The filings for these can get very tedious - especially if your startup has employees in multiple states. Can anyone compare ZenPayroll to a PEO solution like Trinet?
This is something that works in theory, but not real life. Internet is becoming a utility, and most people only ever have experienced one utility in their life. People in the SF Bay Area choose between AT&T DSL and Comcast cable internet - two of the WORST providers, ever. Verizon FiOS eats both their lunches, yet, nobody rabble rouses to ask for fiber in that area. If people in Silicon Valley won't even pressure their politicians (there are FAR more urgent issues), why would people in other areas with far more pressing economic concerns?
I don't get it. Wouldn't it just be easier to install more base stations with a lower transmission strength (essentially leveraging the same transmission frequency more times)?

Thanks. Google returned lot of pages suggesting using celery for async processing. I also read the the tutorial you have provided a link to. Using celery makes sense for deferring processing to another process/time.

If you design an overly elaborate "fantasy" system that you don't actually practice, I absolutely agree. So-called "productivity porn" tends to verge on this problem.

David Allen talked about this - to paraphrase, he said that your real system is what you actually do when you are tired / hurried / overworked and don't have time to do all the steps of your idealized system. (Obviously, he recommends a very simple system that you can practice easily at any time.)

Just what I was thinking. Thinking about how awesome something is going to be when I'm done with it just stalls me out. I have to think: what's broken now, and how do I fix it?

Similarly, when it comes to exercise, I find I'm much more motivated by fear. I will tend to slack off if I don't have a goal, but if I enter a marathon, I'm constantly thinking about how much it will suck if I haven't trained enough, and I am motivated to get out of bed early and run, or run after a long day's work. I feel great after a run, but that's not what drives me.

New Google maps
Yes, but I'm one of the fortunate ones with really fast FIOS and an actual choice between Verizon and Comcast. I wasn't necessarily making this point from the perspective of someone who wants Google Fiber. I was more saying that if Google's aim is to get incumbents to change their behavior, there is value in doing that in your primary competitor's front lawn.

I remember a Comcast exec a few years ago made the point that it was hard to do deals with Hollywood execs because the execs all lived in places in California that didn't have Comcast service, and couldn't really see the innovations Comcast was talking about.
