What does 802.11N change about any of this?

I made a double-long cantenna from some large spaghetti sauce cans years ago and it worked wonders. Then 802.11N became widespread and suddenly all the cards had multiple RPSMA connectors and antennae. Can anyone confirm how 802.11N has changed the recommended use patterns of can antennae? Should I have the same cantenna on each connector, or should they be different to provide differences in signal path for 802.11N magic to work? Could use of (well positioned, well made) can antennas actually make the performance worse than the stock 802.11N setup?
That makes a lot of sense and could have been what happened. It would also make it more difficult for Google to do something like ignore responses that come after 4+ rings.

> I think Facebook as a company is in a strong position.

Just curious, but I'd like to hear your opinion on why this is the case, vs all the naysayers that are betting against the company now. Do you have any specific point you find that Facebook can leverage to maintain success?
Mostly: Less competition for users (e.g. there are 600K iOS apps now - too many), and easier to hire (main alternative right now is to get funding and start a company).

The micro-level counter-examples you provide for macro-level mechanisms simply don't work.

If you consider your first example at a market level, people that are better compensated are more valuable—because they create more value (the discussion is—of course—not around one's value as a human being). The only reason for imperfection in this regard is market friction—which there is a lot of, in every market. But the market value tends very quickly towards the real value if the market is liquid enough.

In a liquid equity market (stock exchanges for example), the price of the stock you buy is its current value. However, you are making a bet on the future value gains of the company. Buying stock for its current value is investing; anything else is speculation.

So here is an idea for an email feature/gmail plugin: 'Semantic Scramble' Basically, any sensitive email that you send to a bunch of people is automatically scrambled (retaining original meaning/correct grammar, just a small shuffling of words) so that each person gets a unique email. Easy to find out who leaked it. You could add a similar unique jitter for sensitive photos/images...
Out of curiosity, why is it that Facebook's IPO would hurt early stage valuations, when all of Facebook's early investors made hundreds of millions or billions of dollars? I could see it getting harder to IPO at a good valuation for a few years, but that shouldn't drive down early stage valuations all that much. Also, to me the most interesting thing to watch (beyond Spain) is these new crowdsourcing laws going into effect January 1st. That has the potential to drive hundreds of millions of dollars into the angel space overnight, sending valuations through the roof or at least keeping them propped up for a while.

I don't think they've even tried to make money yet. They've just been focusing on growth. But they have so many users now that they could do whatever they want. Ideas that would entail a chicken and egg problem for anyone starting from scratch (e.g. marketplaces) do not for them.

Plus Mark himself is such a fearsomely effective person. And so young; he's only a little older now than Larry and Sergey were when they started Google; so he still has the energy and mental flexibility that's usually the only asset of founders just starting out.

Are you using the latest Ubuntu ? They said they improved on multi-monitors support on 12.04. I did not test myself, though.
Three? 2001-2002 was basically nuclear winter in my experience. 2008-2009 wasn't actually that bad except outside tech (although, I was in Iraq and Afghanistan during all of it). Before that, you'd have to go to early-1990s, when I was...12, and some HN readers weren't born.

I do not think that Canonical would share such data. That kind of research costs money, and they want to keep it to their advantage, most probably. You don't see Microsoft or Google release their user studies results either. Hardly surprising.
Yes. Wall Street grades Facebook by drawing lines through dots of revenues and margins. The more accurate way to view Facebook is as a powerful coil that can spring in multiple directions. (I say this as someone who questions whether Facebook is a positive force on the web).

I was thinking of 2001-2002 (genuine downturn) and then separately 2003-7 (great time to invest - e.g when I invested in Skype). Obviously 2008-ish (RIP good times) was the 3rd. Maybe I shouldn't have called them "downturns" but instead "depressed VC periods".
But I think, its now going to be all the more tough for them to figure out how to improve their ARPU dramatically, as they don't have the benefit of obscurity.

For example, even slight change to the feeds, like inserting what vaguely seems like an Ad, raises a huge uproar from people.

In contrast Google had got Adwords figured out (but it was not as widely known) before their IPO.

I have always enjoyed reading this guy's blog-definitely worth a look. At least from the posts i've looked at, the blog's primary themes are: (i) Machine Learning, with emphasis on concise explanation of the key components, nearly always supported by reference to the key equations and simple clear graphics; and (ii) Distributed Processing in the context of BI Infrastructure. I haven't read any posts in the latter category.

Straightforward explanation of the the key concepts of many of the major ML rubrics by someone who clearly has a strong grasp of those concepts himself, without diluting or "dumbing down" the content, but rather relying on simple clear graphics to illustrate the subject matter--is always worth reading, no matter how many times i have read the same content from other sources. Clear explanations always give me a fresh perspective.
It's actually quite clear. Much like printing money takes value away from savers, naked short selling takes value from existing stock holders.

The lawsuit between Overstock and the banks concerned a phenomenon called
naked short-selling, a kind of high-finance counterfeiting that, especially
prior to the introduction of new regulations in 2008, short-sellers could
use to artificially depress the value of the stocks they’ve bet against.

Re: "Semantic Scramble", this was/is used quite successfully in a university course I tutored. Students are supplied with Java code featuring a unique comment style (/ * */). So many students blindly copied code out of another student's assignment and submitted it as their own that we could effectively generate a map of the plagiarism without even looking at the code -_-

Easy solution: just read material that you find interesting enough to remember. Any book that I read I remember fairly well. I often read through paragraphs a couple of times if they have a lot of information or interesting developments. If I try to read a book I don't have interesting, then I just don't remember. I have to re-read it over and over to really get information to stick if I need that information to stick, which was the case in high school English classes.
I think many people misinterpret the IPO crash. It's not that the market thinks Facebook is a weak company, or in a weak position. I don't think there are many financial analysts that would say Facebook as a business is on the decline (a la RIM). The return was simply not worth the price at the previous valuation.
I think YC got a small amount as a result of an HR acquisition, but I'm not sure.

Off topic, but the whole notion that tech industries "disrupt" other industries outside of tech is confused.

If we list tech companies that massively disrupted non-tech industries, you come up with a list like:

* Napster

* Wikipedia

* Craigslist

* AirBnB

If you list companies that didn't disrupt non-tech industries, and created new value, you come up with a list like:

* Apple

* Microsoft

* Google

* Facebook

* Oracle

* Dropbox

Based on my naive list of companies, disruption of non-tech industries seems overrated.
Sad that once more the most upvoted comment is negative. Congratulations for attacking a problem like this one.
Although it is common thinking in the business world, teamwork is not a panacea you think it is. Maybe if you are working on rote J2EE or .Net software you can do four hours a day of work and know exactly the time it will take to complete, but you aren't going to be working on the same project with full timers. Someone working full time is going to complete the same work in two days that a part timer is going to do in seven. Full time workers are not going to wait an additional five days for dependencies the part time guy is working on. And they're not going put dependencies in place, then wait for the part timer guy to add 150% to the schedule finishing their part. This is not bad teamwork. This is scheduling.

I know you are not suggesting this, but I should point out that the idea that the team does tasks as a group around one computer is the amateur's view of software development. In this instance, one might think that part time is feasible because they will just join in on whatever the ONE task that the group happens to be engaged in. I see this a lot in inexperienced managers who think software development is like a meeting except with a computer to type on.

Part timers by definition are not fully invested. Their work is defined by time constraints rather than project delivery. What will you do if four hours is not enough, work four more hours?
I think the thing that people need to remember is that Facebook really only IPOed because the had too. If Google had tried to wait things out as long as Facebook did, then it's quite possible that it would have IPOed near $100b (Sep 2005) and grown to the $200b they are at today.

The money that was there to be made in the Facebook IPO was made before Facebook went public in the secondary market. For professional investors that are getting in at the seed round until the C round or so, Facebook isn't indicative of a problem. Those investors can still make money, it's just that they are going to exit via secondary markets now instead of an IPO.
Generally in high security environments, you don't transmit sensitive information on systems where you're one button (intentional or accidental) from sending the information to the public.

Clearly labeling every instance of the information with how sensitive it is also helps (per page or per paragraph).

It's unrealistic to build a separate semi-airgapped network for most business purposes, but email is broken for sensitive information -- some kind of document room/DLP/etc. system is probably a good idea.
Having a bare repository on the same server as a "deployment" repository, where the repositories are configured to

1) automatically pull changes into the deployment repository from the bare repository

2) automatically push changes into the bare repository from the deployment repository

feels like a hack. Maybe git needs a concept somewhere between a normal and a bare repository, where the files are checked out but aren't teated like a normal work tree, i.e. you can't commit anything, and on a merge any local changes are thrown out?
Don't use this approach; your http-accessible directory does not need a git repo living inside it.

Just have your script export the repo contents by using `git archive` —thereby exporting just the files you created, without any git machinery—instead of this approach.

FB is a strong company and they'll probably get back to a $100bn valuation in a few years. However, I don't think FB is the source of the current tech boom. It is driven by smart phones and app stores. Suddenly, there are a billion people walking around with internet tablets in their pockets. FB benefitted from this new platform just like Instagram, Dropbox, Airbnb etc.

Just for perspectives on "all the naysayers that are betting against the company", the percentage of stock on loan (e.g. for shorting) for Facebook was about 1% versus 5.3% for Zynga and 4.1% for LinkedIn as of May 23rd (the most recent I have data for) per Bloomberg.

LinkedIn for one, despite way more short-sellers than FB and despite the past month or so, still seems to be doing okay despite "all the naysayers that are betting against the company". Facebook is complicated, but undoubtedly is well-positioned for a lot of potential upside.

(Disclosure, I don't have positions in any of the companies mentioned here nor do I intend to initiate any in the next 72 hours.)

Changes to Facebook are like fluctuations in gas prices though. People grumble and complain, then just go ahead and don't change their habit.

I'm pretty conspiracy-theorish on the whole Facebook thing. A part of me wants to believe Mark managed to hack the entire system. He got the maximum amount of money out of the IPO to build up a huge cash reserve for his company. He made his big acquisition before the IPO; future acquisitions may be harder now that the share price is what it is. But he has also sent a shock wave through the entire eco-system. If things cool off a bit, he'll be able to find more talent to work at Facebook at more reasonable prices. He won't have current employees looking to run off and start a bubbly startup. It just seems like a brilliant hack :) I'm probably reading far too much into the whole situation.

During this cooling off period, Facebook can disregard their short term share price and experiment wildly until they figure out something that works. There's not an investor alive who thinks there's anybody more capable than Mark Zuckerberg for Facebook CEO. Nobody will oust him in the short- to medium-term.

Facebook is a very much in the same position that Amazon.com was in around 2001. They have the means to figure this out. Other startups trying to follow suit don't have this luxury any more. But Facebook sure does.

EDIT: For context, this was a contrarian opinion of Amazon.com in 2001 http://money.cnn.com/magazines/fortune/fortune_archive/2001/...
You have to be careful with that list.

You need to look not just at the direct products produced (which may not be disruptive in the classical sense), but also at the positive externalities that they effect.

Apple made the computer personal when it was founded (or at least that is my impression). That didn't disrupt too many people, but think of all the secondary effects. People could learn to program, people could automate things, they could reduce their reliance on word typesetters, photocopiers, radios, television, encyclopedias - the list goes on.

Oracle did kill a lot of big government/company paper waste (not that there isn't any left :), and stuck it into databases, effectively wiping out an industry and creating the new data warehousing/analysts that we know of today.

Google makes research/discovery democratic - instead of editorial. It allows people to directly connect with what they want (information/news/stuff), disintermediating a lot of advertisting channels at a lower cost (TV/Radio/Newspapers especially).

Microsoft got "a PC on every desk", think of all the secondary effects of that (networking/internet/app development/programming tool etc.)

You see my point?

Ok, here's the full quote:

Last week, in response to an Overstock.com
motion to unseal certain documents, the
banks' lawyers, apparently accidentally,
filed an unredacted version of Overstock's
motion as an exhibit in their declaration
of opposition to that motion. In doing so,
they inadvertently entered into the public
record a sort of greatest-hits selection of
the very material they've been fighting for
years to keep sealed.

And now let's parse it:

Last week, the banks' lawyers filed an
unredacted version of Overstock's motion
as an exhibit in their declaration of
opposition to that motion.

This means that Overstock's accusation is now public. This says nothing about the veracity of the accusation.
