I'll have to try some VT cheddar sometime. I stopped defending cheddar's taste (which is none, though I still eat it) ever since I was exposed to real cheeses in my junior high French class.

Looks doable in a straightforward, simple, elementary way:

We start with some background in 'signals'. Suppose for time t we have real number u(t). Suppose we have a 'time invariant linear system' and send in signal u = u(t). Suppose the signal that comes out is s = s(t). Suppose the 'transfer function' of the system is H = H(w) for frequency w (H must exist because our system is time invariant and linear). Suppose U = U(w) is the Fourier transform of u and S = S(w) is the Fourier transform of s. Then, presto, for each frequency w,

S(w) = H(w) U(w),

and the output s = s(t) is just the inverse Fourier transform of S = S(w).

If for time t we have only a finite interval and for the signal have all the power in a finite 'band' (have a 'band-limited' signal), that is, have a maximum frequency with any power, then we can discretize both time and frequency and use the fast Fourier transform (FFT) to do the Fourier transform work (actually a non-trivial signal cannot be both time limited and band-limited at the same time, but as we discretize time the signal can be band-limited and zero at all our discrete time points outside of finite interval of time -- don't worry about such things!).

Suppose for some positive integer n we have n transmitters at distinct geographic locations. Suppose we also have n receivers at distinct geographic locations.

Suppose for receiver j = 1, 2, ..., n we want to send to receiver j signal s_j = s_j(t) for time t. Here we are borrowing from TeX where _j indicates a subscript.

Suppose by sending 'test signals' we have, for transmitter i = 1, 2, ..., n and receiver j = 1, 2, ..., n, 'transfer function' H_ij = H_ij(w) where w is frequency.

So, we want signals u_i = u_i(t) so that when, all at the same time, for all i = 1, 2, ..., n, transmitter i sends signal u_i, then each receiver j receives the desired s_j.

Let U_i be the Fourier transform of u_i and S_j be the Fourier transform of s_j.

Then borrowing from TeX, for each frequency w

S_j(w) = sum_{i = 1}^n H_ij(w) U_i(w)

Now pick a particular value w of our discrete frequencies.

Let's let S(w) be the n x 1 matrix with S_j(w) in component j, H(w), the n x n matrix with H_ij(w) in component i, j, and U(w), the n x 1 matrix with U_i(w) in component i.

Then we have

S(w) = H(w) U(w)

where on the right we have matrix multiplication of n x n H(w) and n x 1 U(w)

Then

U(w) = H(w)^(-1) S(w)

where

H(w)^(-1)

is the inverse of n x n matrix H(w).

Do this calculation for each w and have all of U = (U_i). For each i = 1, 2, ..., n, take the inverse Fourier transform of U_i = U_i(w) and get u_i = u_i(t). Done.

The math was not very advanced! Sorry 'bout that!

But there is an issue with Shannon's theorem: As n grows, the total power in the signals u_i, i = 1, 2,, ..., n, stands to grow. Shannon's result was for bounded power on the communications channel or at least bounded signal to noise ratio.
I must have grown up in a different part of the city than you frequent.

Families in my neighborhood were not hardworking, or honest. The vast majority of them were either petty criminals (most of my friends growing up stole cars or robbed liquor stores) or in organized crime (like my family). Everyone had a scheme, or an angle they were trying to play to get money quickly.

When I go home now, I never feel like I'm back there until I hear someone call someone else "fucking retarded" (never been more than a few hours).

I'm not disagreeing with your characterization of "salt of the earth Boston people", I'm just saying that like anywhere, people aren't all the same.
Yay! on vararg SADD and ZADD.
I was responding to this: "One of the key things that Goldman has (as a hedge fund) is the ability to see what all their clients are doing...Hedge Funds, OTOH, are used to being spokes, rather than hubs, and so don't expect to know what everyone else is doing."

A market maker is merely a prop desk running a particulra strategy. They have no information on Goldman's clients. They behave exactly like any hedge fund.

Insider trading is a red herring, I don't know why you bring it up. Mdda claims Goldman is breaching their fiduciary duty to their clients.
Ask HN: Showing personal projects to potential employers
I've heard that when I go to look for an internship one of the most important things for a potential employer will be the projects that I've done in my free time.

This will vary from employer to employer, but what is it that you would be looking for when you see my projects? What would get me bonus points and what would make me lose points? What is important to you? Good documentation and commenting? Optimization? Apparent effort? What is a deal breaker?

武汉凯德盛投资管理有限公司
Trust me, anybody who's rented to more than a couple of people has experienced it. Anybody I've talked to, anyway.

As to who these people are: it's a mixed bag. I keep wanting to write some kind of tl;dr screed here, but ... it's complicated.

I'll say this, though. I went to school with a guy whose dad was the manager for an American-owned automotive plant in Spain. They lived in a freaking mansion in Cadiz, although they were basically regular people from Cleveland or Akron or someplace. But he basically grew up a lot richer than me (and considered me bourgeois, but damn we were young and foolish).

He told me the story once about how he'd been depressed and visited a friend of his who was housesitting for their teacher at the American school there. I.e. another rich kid. So what this friend did to cheer him up, among other things, was to set up a target and throw knives at it. Except instead of knives, they destroyed every pair of scissors in the house and used the halves as throwing knives, you see. He laughed about how the teacher must have been perplexed about having no scissors when he got back from his trip.

I'm sure that he'd be mortified to know that I remember this story twenty years later, which is why I'm not naming names (yes, Mr. Google, I'm watching you!)

OK. So extrapolate that rich kid's behavior - and this was a good guy who I really liked - to our original post here. It's the same thing, just a lot more extreme. There are just people who think that kind of exploitation of the vulnerability of others is funny and fun, although I'm sure the vast majority grow out of it at some point.

It's kind of like sociopaths, I guess, as abused as that concept has gotten lately. I think there are those of us who would never have considered finding all the scissors in the house they were entrusted with, and tearing them in half for knife throwing. I'm one of those people. You probably are. And sadly, AirBNB is probably made up exclusively of that category of people. And probably the vast majority of users of AirBNB also fall into this category.

Now, one didn't. Honestly - I think the only way AirBNB is going to weather this is to have some serious, serious talks with an insurance provider and have some kind of blanket coverage they can extend to their hosts, perhaps with an additional fee - but they're not going to get through it with just being nice guys. Which arguably they are.

So that was really more than I intended to write. Sorry.
Ouch. So ideas are not bad but the language hurts someone's ego. Guess Andy Rutledge won't get any recognition because of "the wrong approach".
Somewhat more content on the Wired post, true, although I was kind of put off by Wired's report calling Alibaba an 'obscure' company... in any case, both appear to be sourcing their information from this Penn Olson post from earlier this month:

Education is mostly about emotional communication. If you can communicate Emotional Space and Respect to someone and you can give them a compelling Emotional desire for why to learn something, and you consistently exemplify the skill, learning is very automatic. It happens in the animal kingdom all the time.
I can assume by your response you didn't finish the article. The last paragraph is the opposite of what you are saying:

"I will say this, though: unsolicited redesigns are terrific and fun and useful, and I hope designers never stop doing them. But as they do so, I also hope they remember it helps no one — least of all the author of the redesign — to assume the worst about the original source and the people who work hard to maintain and improve it, even though those efforts may seem imperfect from the outside. If you have good ideas and the talent to execute them and argue for them, the world will still sit up and pay attention even if you take care in your language and show respect to those who don’t see things quite the way you do."

Enterprise Linux by any other name
I’ve been doing a fair bit or reading and writing and talking about different versions of “Enterprise Linux”, and the more I talk and think about it, the more I come to realize that I’m not as comfortable with the definition of that phrase as I would like.
It never really could.
Yup, that was Altavista.
I was wondering how the good universities from across the Europe (particulary from UK) are being perceived in US. Places like Edinburgh University for example, even though they are very good, are way lower in ranks than the american schools.

The same funny thing happens with the technology intitutes from eastern europe. Some technical degrees are horribly demanding and produce some great engineers, but still are very low in the world-wide ranks.
This is absolutely correct and is an important distinction and I do confess that my statements were not very precise from that regards. However, I had a long discussion with a law professor at Berkeley where she did agree that the US Common Law is highly influenced by the French Civil Law, though many law academic in US will take an exception at the statement. Also, IANAL either but am taking a few law courses here.
Because the ghost named Idempotence appears?
Yes, you are right. I'm politely telling you that I respect your opinion but I disagree.

>>Are you incapable of substantiating your position?

The thing is that a lot of the arguments we are making are just our own opinions and hence anecdotal. Really what we need here is scientific research measuring what difference does the programming language make when working on coding projects

A couple of examples that I've worked on are the following:

A Java to Objective-C transcoder

C to Java transcoder

Physics Engine

Collision Engine

Symbolic Math Engine

Game Engine (includes the Physics Engine and Collision Engine along with the rendering and animation code)

And some things I'm currently working on:

Java to C++ transcoder

Java to JavaScript transcoder

What I've noticed is that the coding takes very little time, the figuring out part, the design, architecture, debugging, that takes most of the time.

I'm not really sure whether one of the most modern languages would really make much of a difference if at all. I believe it won't really make much of a difference. Coding is the easy part.

Use the language that makes you comfortable, definitely.

Now, tools are a different story. I would hate to have to code in a simple text editor. IDEs make my life extremely easy and actually make me a faster coder. I love the Eclipse IDE. XCode would be my second choice and Visual Studio 3rd.

Getting pissy about it doesn't change the fact that the Hurd serves no useful purpose and doesn't have an interesting idea animating it, just a series of shop-worn ideas from 2 decades ago.

If I spent my off-hours building, say, a slightly different clone of Java that I'd started in 1996, you'd be entitled to tell me that I was wasting my time. In fact, this would be doing me a service. If I couldn't turn around and say, "well, Onanva is different from Java because of interesting features X, Y and Z" or "Onanva is about to take over from Java because I've got 100K users in beta and they're screaming for a commercial version" or whatever, then I'd have some serious introspection to do. What I wouldn't do is go into a screaming frenzy that someone who is "sitting on their ass" (whatever that means) is disparaging my precious, precious work and start running around with my dress over my head.

I can't tell from your profiles whether you or Mr P9 have ever been in an environment where you get asked tough questions, but any decent CS school will make you run the "why is this interesting/useful" gauntlet repeatedly, especially if you want to get a PhD or something silly like that. The bulk of the cruel, cruel people who ask you these terrible questions will do so from a seated position, and it will be imperative on you to harden up and supply answers. Not every hobbyist has to deal with this sort of thing, but not everyone outside industry or academic research is incapable of doing so; see also Young Torvalds vs. Tanenbaum for a less pathetic approach to criticism.

Programmers are free to do whatever they want; I doubt that a better OS will have much to do with the "betterment of society" in any case (you're not sure what I'm suggesting, but you're sure it's "quite offensive"). IMO they should work on projects that are objectively interesting. It's ok to disagree on what that might be, but no-one has been able to furnish a reason why building a UNIX clone on top of Mach (again, after cycling through several other underlying microkernels) is in fact interesting in 2011.
Timely tweets now easier to see
It's ironic, but predictable.

A site full of hackers is good at picking apart a naive technical idea... not so much a naive design idea.

The bigger irony is if you had these discussions on news.ydesigninator.com, the designers would have no opinion at all on the code, because they would realize that they know nothing. But with visual arts, it's easy for us programmers to bike-shed and act like we know something.
Santa Ana Short Sale is available worldwide 
Sellers in any real estate market are looking to get the best possible price. If you are looking to sell in the next year, today’s price may well be the best price. Home values stabilized somewhat in 2010. Many hoped that was a sign that values had bottomed out and we would see price appreciation in 2011. Studies released this week have painted a different picture.
>Are you really comfortable with the idea of potentially stunting one of the most important aspects of your child's abilities --- their ability to interact positively with people? (People other than you. People who don't already like your child.)

heh heh... as someone who's been thru the public school system, I can safely say I don't WANT my kids learning the sort of "social skills" you learn there. You describing it as "interact[ing] positively" has me convinced that your story of not having gone to public school is true. :p

It's funny that people always bring this up: social skills. Have you met many home schooled kids? They are some of the most mature, well balanced, intelligent kids I've met. Secondly, what do you think home schoolers do, live in a bubble? Contrariwise, they interact ("socialize," if you prefer) with kids of all ages, as well as adults, in a normal, "real world" context.

As for "stunting" my child's abilities: I am absolutely certain public school does this, so I'll take my chances, thank you very much. I don't appreciate your insinuation, by the way.
That's not true. Expanding market share can mean selling at lower price points, which in turn means lower margins and potentially lower ROI. Moreover, the simple ways around this, like keeping older product lines longer, have risks in the technology sector not present in other areas. There's a lot of incentive to be not more than two models behind on mobile phones, not so much with cars.
Probably not, depending ont he final wording of the court decision a reasonable demonstration its the same site the same ruling could be applied without going back to court.
I think it really depends!

To date, I have only met one school administrator who was not a petty authoritaria. She was in charge of a tiny school of about 50 people, and was also a teacher there, so I'm pretty sure she was an aberration. Talking with other people has pretty well confirmed it: the kind of behavior you describe is very common. Accommodating an exchange student without a report card, or letting you out of an ill-fitting state requirement, would be inconvenient for them, and would be a precedent for even more inconvenience. Your own welfare is trivial compared to that. And if you argue, then you are an impudent child who must be dominated to re-establish their authority over you. The harder you argue, the more imperative it becomes that they not listen.

One of the great pleasures of adulthood is no longer being forced to suffer the presence of such people in my life.
Thanks. I've definitely seen goldfish before but never really associated cheddar with that bright-orange color. I always called those "nuclear cheese" because of how eerily bright it is. I don't recall ever seeing that in normal block-of-cheese form though, but maybe I'm mistaken.

In VT and NH if you buy any cheddar at all from a farm it is the color of the image you posted and must of it is very fragrant.
I've got to agree with a lot of the sentiment here.

I've got ... a few apps on my phone. Most were pre-loaded.

The big ones: "phone" (that's an application, really), browser, email, SMS, maps, agenda, contacts, camera.

Some administrative / management apps: configuration, WiFi, tethering, torch/flashlight, audible/vibrate/silent/airplane mode select.

Some informational apps: a few commute schedules, calculator.

Radio, music, ssh client. That's 99.99% of my usage right there. A few others.

Notable failures: an RSS reader. Problem: too many feeds offer too little content. I'll just hit the Web.

I've just added a G+ app.

There are a few other odds and ends I might use once in a blue moon, but rarely.

There's only so much time, and for I/O, phones suck. They're good from a here-and-now perspective, but not much else.

I'm seriously paranoid about the data on my phone, and either losing or leaking it. There aren't any particularly good solutions (from a "works" and "I'm comfortable with") perspective.

The notion of app proliferation reminds me of the small-app PC market of the late 1990s (about the time Free Software was taking off). In the Linux/BSD world, duplicate effort generally resolved with one project dominating or two projects merging (there's still some duplication, but not tons). While everyone and his kid brothers dog writes a caculator app for Windows. Which ... don't share data with one another. I see the mobile app world as very similar, and strongly suspect it will consolidate to the Web (for informational stuff) with some exceptions (UI or data requirements dictate local intermediation).

Fortunately I landed an internship in a good company because of my portfolio, not my grades. They saw that I was developing quite a lot of stuff that was not really related to my degree and they liked it.

I would look for something related to the thing that company does, but a range of different thingies created just for yourself shows that you're creative, learn quickly and actually like doing this stuff.

Coding your own projects it's better than sitting and doing nothing so I guess that it's hard to "loose points".
Yes you are. But you can beat it. I didn't go to a good school. In fact I went to an awful school. But I am an engineer at good start up in the Valley and doing very well.
