Agreed about the neck cranker... he should have known to stop well before injury occurred, especially in practice. I would be slightly more forgivable in a tournament, but still should never have happened. BJJ is very technical, which I find awesome. Going to train right after a whole day of programming at work is a seamless transition. The mode your brain already is in lends itself to the jiu-jitsu ideas of thinking multiple moves ahead, and applying logic and technique to your art. Being stronger than the other guy helps too ;-)
Is this actually a problem for people or just a case of something new being considered bad? I find the new slightly smaller font to be cleaner and make the layout nicer. I think it hardly causes anything near eye strain and that if you weren't strained before the difference is unlikely to change that.
Did a quick google search for the term "lists of videos". This link came up second: http://superl8tive.com/

Seems similar to what you're going for, and they appear to have been around for a while.

Checked their compete.com stats to get a rough idea on their traffic, and it doesn't look good. From 1600 uniques about a year ago down to 467 a couple months ago.

And their execution is not that bad.

So given their traffic, similar idea, and length of existence, it doesn't give much confidence that this idea can have a large audience.

Not raining on your parade. Just want to offer this little bit of research and my take on it. I think you may want to push the idea even further given the non-success of this similar execution.

What they're describing sounds a lot like professional blogging: useless, heavy linking to your own crap and summarizing others' articles.

I wonder if they'll go after Engadget next, or Gizmodo or any of the Apple rumor blogs. They're just the successful versions of that 70 holdings company.
Has anyone else had this happen? I can loosen the ban thresholds if it's a common problem with Chrome.
It's interesting how the F# team is pushing F# to be the language for data-rich programming. Their Type Provider concept looks promising, but some of their demos still are comically difficult coming from a R/Matlab/Python style of data-rich programming. Of course coming from C#/Java it all looks amazing.

But I don't quite see how F# replaces R or Matlab, even with library support. Performance alone seems dubious value proposition, since packages like Jacket for Matlab make most computations extremely fast.

Anybody have experience where demand for strongly typed language is really needed for data analysis tasks?

Google's position is completely fair, but they should probably spend more effort trying to not suck at social, and less effort trying to undermine Facebook.

It's pretty remarkable how poor their social products have been, especially compared to other new product initiatives, like Android.

How can Google save its social strategy at this point (other than by trying to chip away at Facebook with tiny measures like this)?
Eh, I happen to think the Perl behavior is just as ridiculous. Defining the addition operator on a string and an integer to create some kind of complete lexographical ordering is completely counterintuitive and, moreover, is probably not useful enough to warrant such behavior.

My roommate bought it and invited a bunch of people over. It's actually a lot of fun. More than I thought it would be. Most people seemed hesitant to play... probably because the majority of the games involve waving your arms around like an idiot. It's not quite as bad as that infamous video suggests, but it's still pretty bad.

The motion detection technology is really good. You walk around the room and your avatar moves along with you. You scratch your cheek with your right hand and the character on the screen makes the same general motion.

Voice recognition was mediocre. Had to repeat ourselves a few times, and background noises seemed to screw it up.

Thumbs up, overall.
I currently have 72 tabs open. Yes, I am a tab addict and I need to go through and close/bookmark many of those tabs (and install a tab limiting extension). However, only a few of those a HN tabs. Many of them are stories linked to by HN.

I have the same exact problem as the OP. I'm running Chromium 9.0.567.0 on Ubuntu 10.04 and a couple of days ago I was getting the same error page. I wondered why I was getting this error. I tried clearing the cookies thinking there was something wrong with my login cookie and using different browsers, but nothing worked.

The only thing that made sense was that my IP was banned, which confused me seeing as I didn't think I had done anything worthy of being IP banned.

Luckily, I saw this post (on a different IP address) and I'm certainly going to use a less bleeding edge version of Chromium from now on.

p.s. If you see this PG, can you please unban my IP? I promise to use a browser that won't bombard HN with requests, and to use less tabs :)

Edit: For the record, I only had 3 HN tabs open. For people wondering how 3 tabs could trigger a flood of requests, check out this reply to PG http://news.ycombinator.com/item?id=1872177

It depends on which dojo you train at. In our (Shotokan) dojo, every couple of lessons or so, someone will ask "but that's illegal in a tournament, right?", to which our sensei laughs and says in a real fight there's no such rules. We are taught to end any fight in one strike. We are taught to destroy the three weak areas of the human body (can't fight if you can't see, can't fight if you can't breathe, can't fight if you can't walk). We're also taught judo, because most fights end up on the ground. We're taught a wide variety of self-defence moves, most of which end with us taking a joint or two or theirs.

I'm sure there's plenty of Shotokan dojos that don't have such a good sensei though. YMMV.

Take EBITDA (Earning before income tax, depreciation, and amortization) and multiply that number by between 5-18. You get a higher multiple through higher growth, long term consumers, sustainability (your consumers won't leave), competition, size, etc.

For what you said you likely are around 10, so if the company doesn't need someone to sustain growth it would be worth around 2M. If it's a talent acquisition or IP does change the calculation somewhat. Now a year from now I would raise that multiple to around 12-14 if you maintain your growth rate.

For about the last week or two I have been randomly receiving the same error:

"Error 324 (net::ERR_EMPTY_RESPONSE): Unknown error."

when navigating to a page. I am running Chrome 7.0.517.41 on both Windows Vista and Windows 7 and experience the issue on both systems. Usually I can just hit refresh and the page loads properly, with no problems. Sometimes though I find myself having to close Chrome altogether and restart.

After reading this I will have to look and see if it is doing something similar when it gets this error. The error is very random and doesn't matter if I have one tab or 15 tabs open. I rarely keep more than 10-15 tabs open at once though.

My old roommate used to be a tab whore -- it got so bad that eventually every time he opened up firefox a million tabs would try to load up and temporarily kill our bandwidth.

Anyway, I don't know how many tabs you keep open but I'm sure a little organization can drastically cut them down (get in a habit of hitting ctrl+w once you're done with a 'dead end' page.) If organization is too hard just periodically close everything and it won't be too bad.

So I guess if you combine Kinect with iOS touch/swipe gestures, you can get the Minority Report interface (without the gloves)!

Not to mention that if Kinect can recognize your face well enough to log you into Xbox Live, then those customized interactive wall adverts from Minority Report can't be too far away either.
The dance game is a pretty ridiculous amount of fun, assuming you like these sorts of things at all. The casual gamer appeal that made the Wii a success is pretty immediately obvious when you see it in action, and they definitely nailed the technology.

That said, the $150 price tag seems a bit steep ($400 with a console). Early sales do look pretty strong, but I'm not entirely convinced this will get more people to buy a 360, especially if they already have a Wii gathering dust.

Personally I'm most interested in the hacks people will inevitably come up with that take advantage of the technology in different contexts.
Why all of the sudden? Upgrade regression?

I want to see this hacked and be able to connected to my laptop so I can write programs using the Kinect sensor as an input. Think about how wild it would be to write software using a Kinect input as a sensor. For example, you could sit there and wave your hand to move through your email or music or something.

I'm not the only one; Adafruit Industries has a $2,000 bounty for the first Github repo submission that can grab input from the Kinect device and output depth. http://www.adafruit.com/blog/2010/11/04/the-open-kinect-proj...
I've actually had the chance to play with one of these firsthand, and I must say, I'm quite impressed. The only basis for comparison I have is the wii.

Initially, there is some confusion as to what it is you're supposed to do but after a minute of awkward movement you get the hang of it. This feels much more natural than the wii, and the lack of controller is freeing. The full body movement detection is fun and really encourages you to move around. On the other hand, the sensitivity is not that high. It's okay with the casual games it comes with, but I'd like to see some more examples of, say, shooters.
Maybe I'm dense but I can't figure out what kind of bug the OP is claiming is acting up here. Does Chrome just sometimes decide to send hundreds of HTTP GET requests for no reason? Is it attempting to pipeline per the HTTP spec and just screwing up? This article is so high on rant and low on information I can't tell what's going on. Have you checked if there's a bug report or filed one yourself?
People with their head buried in low-level details are frequently - in my experience - worse at higher-level code organization and abstraction.

There's two things at work. Some people's aptitude for handling complexity lulls them into relying on it to get themselves out of tight spots, rather than learning to architect their code better; and they wind themselves up tighter and tighter. And on the other side, "app dev", people are pulling together a lot more constraints than the bit-twiddling level, combining user stories, business strategy, long-term supportability and team development, UX, and a bunch of other things which, while more nebulous and less concrete, are usually more important, economically speaking.
Around September I started noticing slowdowns and timeouts, and I haven't added any new lab features. Either Google is running into scaling issues, or they upgraded something (front or back-end) that was a regression as far as performance is concerned.
Well, it was a problem for me, so I fixed it, and thought I'd share :)

Notably my 2 issues were:

1) My eyes hurt so much that I preferred using my iPhone over a 24" screen. After installing this, my eyes are feeling much better. Maybe I'm just old.

2) Before, my Friends' status messages were 13px, everything else was 11px. I prefer that my friends' thoughts be more important than UI chrome.
I understand it's a bit superficial to re-enforce the common sense rejoinder discussed at the end about not using developer builds.

- but isn't the idea of using a developer build at least partly an issue of wanting to discover bugs like these and report them, as opposed to just getting access to the latest and greatest new features? You know, so you make a contribution to the cause?

It is annoying though that an install of both chrome devs and the ie9 betas overwrite the stable versions. The firefox beta at least installed elsewhere so I can easily use the old version if I like without having to dick around with it.
aye, i use trustkeeper. it's a steaming POS.
Hmm, perhaps it could. The strategy I was trying to suggest is to try and get progressively elongated stretches of time when the person would not have alcohol. It slowly can help wean off the addiction.

This is a joke right? You opened a lot of tabs, were surprised that it sent a lot of requests, and are blaming the browser?

Am I missing something? If you save your tabs and reopen them, what exactly do you expect besides it trying to... open them?
This is great news. I've been following Wayland on Phoronix and I was hoping Google was going to do this when they announced Chrome OS
In the early days of the AppStore you could drop your price to $0, then switch to paid, and retain your ranking. Apple quickly quashed this, so perhaps these apps are looking to benefit from word of mouth, or to gain a number of reviews. As I mentioned earlier you need 5-6 reviews before you even get a rating and having more certainly doesn't hurt.

On a similar note, I believe Apple's charts may now be weighted to take price into account, at least in some form. I occasionally play around with app prices to see how sales/revenue/in-app purchases change, and last week I upped the price of one app from $1.99 to $2.99. Sales dropped from ~400 to ~250, but my chart placing was virtually unchanged (I think I dropped once place). I don't believe the ranking is based on sales over a period of days, though it may be a factor, since my ranking does increase/decrease with normal sales fluctuations.
I am also experiencing these issues. I've heard this issue is usually limited to big and/or old accounts. I've had my Google account since it was in Beta, and it's 48% filled.

Gmail has been so unbearably slow for me that it forced me to switch from Firefox to Chrome on a Mac. In Chrome, it's much better, but still very slow.

In fact, I just got Office 2011 and trying out Outlook.. I've used to be a devoted Outlook user before I switched to a Mac and went 100% Gmail for all my personal & professional mail. But Outlook 2011 for OS X seems awesome so far, so maybe this will be the end for my Gmail experience.
It's a good idea. Similar to Taskpaper (http://www.hogbaysoftware.com/products/taskpaper), I wish you guys the best of luck.
My advice would be the following: look at the common questions students have and give 2-3 specific examples (with screenshots) of how they'd use your product. For instance SN1/SN2/E1/E2, figuring out nomenclature, reactions of alkenes, etc. Show how your downloadable guide solves their specific problem.

BTW I'm basically in your exact same space: masterorganicchemistry.com
I have always thought that GA have won lot of acceptance for its name. Don't get me wrong, they are great to solve some problems, and even though they don't assure us to converge into a global minimum on our space, they are more robust than other methods to search in the whole space.

We can see a relation with the humans, I am pretty sure that we are not a global minimum in evolutionary terms, but... certainly we are at least close to be a local minimum.
Ask HN: Open Location APIs
These days there is a lot of talk about location (4sq, FB places, etc). I am curious which services out there have open APIs that one can use to create mashups (and just generally query).

I ran across an old HN article -- http://news.ycombinator.com/item?id=216112 -- which is an interesting start, but being over 2 years old is a little dated.

I guess my question is simply -- what services out there allow location based queries to their data, what rates/limits do they put on them, and are there ways to getting greater access (for instance w/ Twitter -- the firehose vs. normal account query limits).

If there is already a good list, please share that. If there are some hidden gems, I'd love to hear those too.
Ask HN: who here picks up girls on a regular basis

I think plenty of people said the same thing about the Wii. It is fun so long as games use the interaction as a constructive part of the game. There are plenty of fun multiplayer games on the Wii that just wouldn't work with traditional controllers.
If you want a corporate finance answer...

Assuming you can go on forever, you are a perpetuity with annual growth g = 79.58% = ~80% (1.05^12 - 1), coupon c = $200,000, and some value of discount rate r, which you could otherwise get with your money. For our example, we'll suppose you can invest somewhere and get a 10% return.

The formula for a growing perpetuity = PV = c/(r - g), where PV is the present value. This formula only works if the growth rate is less than the discount rate... following this rule, we have to use a higher discount rate, so we'll assume you can get 100% somewhere else (let me know if you have a place where you can do this.)

If you take the series of system payments, then you would have:

PV = c/(1 + r) + c(1 + g)/((1 + r)^2) + ... + c((1 + g)^n)/((1 + r)^n)
which ultimately equals PV = c/(r - g)

PV = 200,000 / (1.00 - .80) = $1,000,000

So $1,000,000 is the amount someone would be willing to pay for all the present values of all future earnings on the perpetuity, assuming you have an r = 100%.

If g > r, then the growing perpetuity would (theoretically) have an infinite value.

edit: added value = $1,000,000 assuming r = 100%
I had a Wii for a while, and the motion control thing was fun at first, but it wore itself out pretty quickly. I think the thing I appreciated most was the ease of aiming when playing Metroid.
There is a third, correct choice: don't allow incrementing of strings. Everything you say about comparing is true, but that's a separate issue.
Ask HN: The one thing you believe is true, but most people think is untrue?

From the article -- 'No one solution is necessarily "better" overall.' No truer words are there to live by.

Having an interest in Location based stuff recently, I started looking at assorted NoSQL solutions. GeoCouch and Mongo are at the top of the list, having gotten the most recent attention. But one list I ran across had many options that I had not heard of, it is a serious maze and can suck up a lot of time.

My plan is to start with the obvious two that came up (CouchDb and Mongo) because they are well known. If either meet my needs, I am done. If there are limits that are hard to work around, then I will widen the search and look at other options.

There are a lot of options out there, try determining your major use case/need and filtering based on that. Then expand the search if you are not meeting your needs.

It did happen to me, with a developer build of chrome on windows several months ago. I took it as a sign to moderate my HN habit and got another IP from my isp. Actually the moderating part hasn't worked out so well, so if there was a problem it's gone.

The right way to do this is by adding rel="nofollow" to the links.

Also great advice for any startup displaying user submitted content publicly to the web. Adding rel="nofollow" to links with low karma will prevent people from spending the time to write a custom spam bot for your site until you have enough traffic to matter for that alone. You'll still get the drive-by spam if it's easy to submit, but you can get around that with an unconventional form.
'z'++ is not 'aa'. 'z'++ is not even valid PHP. $z='z';$p=$z++; does nothing either.

Sounds like he has an ungodly amount of tabs open and Chrome isn't smart enough to say, "Hey, I have 50+ tabs open on the same website, maybe I shouldn't try to refresh all of them at the same time."
As long as we're enforcing ordering on casually unordered sets, when not define it as length of the string? Now 'aa' is certainly greater than 'z'.
