Actually i'm curious now that every car will soon have its own black box how if this technology becomes ubiquitous what the law enforcement agencies start asking for.

As cool as google glasses are, imagine they become "effectively needed" as a technology. Then it becomes almost a foregone conclusion that law enforcement will want access to it. While I can imagine bad outcomes, what about things like alibis and so forth? We always touch on the bad uses of technology, but for once can we approach this from the opposite direction? Along the lines of the Russian meteorite, lots of video was captured by chance due to dashboard cameras meant for stopping fraud. Lets imagine a society that has equal access to everyone elses google glasses streams. While I can imagine a dystopia, I can also imagine some rather interesting societal developments from it as well.

I'm thinking along the lines of a short story I read a while back where everyone had their upper vertebra removed and some tech installed that would record everything a person saw/did literally and everyone else could know when other people looked at their own data and when. Aka, ooh i need to call bob, but lets see what he's up to first because I don't want to interrupt him, oh he's with susan at a good restaurant, guess it can wait. I think this technology could have great uses as much as it could have bad. I only expect bad use from our government and police forces, but that is more because they always want more access. But the converse is think about crowds, we could start identifying agent provocateurs, and mass recording and uploading bad acts. These are as much an agent for change in the system as they are for oppression not?

Thoughts? I'm just rambling now and need to shut up, if you read this far I owe you one beer. :)
Having tested the interactivity of various WebGL applications on low-to-medium-end graphics cards, I will say that Chrome's does have significantly higher latency than Firefox. Try this demo:

http://n3emscripten.appspot.com/instancing.html

Crank the number of instances up until the frame rate drops (on my Intel HD Graphics 4000 it's about 20,000) and then drag your mouse. Notice that the drag latency is significantly worse in Chrome than Firefox.
This is why I'm scared to invest too much time into something that isn't directly for my benefit.
After reading your article and looking at the site, I think you might be pulling the plug too early. I have been in the same boat before. You spend all the time to build something, you believe it's got legs and then....radio silence. Then you get some interest but it never really takes off.

I would bet that if you really talked, like physically talked (phone, Skype) with your users, especially those who haven't been active for a while, you might start to learn more about what you need to do to gain more traction and develop the product further.
Completely agree. One way to 'solve' this might be for it to stop when you hit the top, then wait for say, a half-second (prevent all scroll up events during this half-second if you're at the top of the page). If the user scrolls up after that, do the refresh. Maybe someone will think of an issue with that, I haven't really thought it through.
A SimCity for Analyzing Urban Efficiency
In the best touchscreen implementations, you have to overscroll past the top by a certain amount to get the reload behavior. Further, while overscrolling less than the threshold amount, you get a visual hint that further pulling will reload, while letting go will avoid a reload.

This Hook.js implementation doesn't yet seem to have that level of refinement... but if it could, I don't think the user expectations or conflated-functionality issues you raise would be fatal usability problems. You could have the benefits of cross-training with touch, and easy reload access via the already-under-finger scrolling-controls, without much confusion.

(Though, truly seamless operation might require in-browser implementation, to trigger without interfering with the usual DOM-coordinates Y-zero.)
As skakri said, this breaks the 'scroll to top' shortcut (whether it's Home or cmd-up). The behaviour in the twitter app for android is making the best of a bad situation (screen real-estate in short supply but touch gestures are available). It also requires you to deliberately scroll beyond the zero position into extra space, so you can't accidentally scroll too far.

usehoook feels like a gimmick for the sake of it, and it lets you do things, possibly destructive things, accidentally and without meaning to to.
To deal with this, the author needs to clearly separate the two actions. If a little arrow appeared when pulling down (to indicate further action is required) and a pull to refresh meant pulling down by say 1/3 window height, the two actions could not be confused. As it is if you scroll near the top of the page you can trigger it by mistake, I agree this is confusing.

Still, for certain web apps like gmail (which already does this), it's a neat shortcut for those using gestures. Possibly works better when confined to a list as well, so I'm not sure about applying it to an entire page.
I currently can not distinguish trusting them about stats vs about blood spatter, bit mark, DNA, evidence.

Why should I trust them less for stats? Math does hold a honorary position in society while also being often being disliked(USA here) I will have to think about weather that is enough to single stats out from the others.
The pricing is competitive, its easy and reliable, and it can handle as much traffic as you like. S3 may not be the best option, but it's definitely a good, no-worries option.
Anything is easy to find once you've already been there. Why did the driver in the video take those specific turns? I can't see any signage.
I've two teenage kids albeit a little younger than yours.

I found one way to hack their stomach share is to stick cut fruits/carrots on the table when they're doing homework. Another technique is to introduce subtle variety into the shapes, kind of like how pop songs have the same tune but a lot of work goes into varying the accompaniment. With carrots, give them a mix varying thickness, length, tapers etc. Observe how they eat. They'll start to play with the shapes etc.

Since you have daughters and they'd listen if you knew something tricks that'd help with weight. Talk to them about set points.

The level of sugar, salt and fat we prefer depend on what our "set point" is. A set point is like a thermostat. It determines what we feel is comfortable or not.

If you go to developing countries, you will find cakes and biscuits that are very plain tasting. It isn't because they don't know how to make cakes and biscuits. It is because the people have a different preferred set point. If you serve them typical American desert, they will actually react in disgust because it is overpowering.

The same with soft drinks. A person who consumes soft drinks regularly raise their set point for sugars. To the extent they will no longer drink plain water. One only has to look around at their friends to realize this is going on.

The trick though, is this - the set point can be altered. There are two parts to this - water, and attention.

Drinking plain water regularly will, after six to 12 months, increase your preference for water. It will also alter your set point that after a while, you will find rich foods a little too rich for your liking. Going cold turkey for two weeks can be very helpful when starting out. Initially, water will taste disgusting. But your ancestors have been drinking water for millennias. Put up with it for a while and your set point has to be down-regulated. I personally know of someone who lost 15 kgs from just changing their water-drinking habit alone.

Paying attention is another method. One of the common problems is food manufacturers have flavored their food to suit inattentive eating. Paying attention to the sugars in your foods will cause you to notice how overpowering it is. The same with salt.
Very nice. It's missing using the volume buttons as a record button though.
Preventing fraud in digital goods - advanced tips
Perhaps you were being tongue-in-cheeck, but I do feel the need to point out that the grandparent said they were using Safari, implying that they're on OS X.
God, I abhor this sort of peevery. But especially here, when the linguistic innovation is so damn useful.

The "trendy" meaning of trope, is, as far as I can tell, not one easily replaced by another word. It's not a motif so much as a kind of generalization of what archetype is to a character. In its narrative sense it refers to the sort of "tools" and "parts" the story teller uses to construct their tale, and I absolutely love the extension of meaning to refer to UX... tropes (what word would you use here? Motif? That suggests to me more aesthetic design elements than things like pull-to-refresh)
numbers suggest around 2% accuracy (7.1)

It's more likely he just rounded a number of results and rounded to the first decimal place to display it better, not to suggest some level of accuracy.
Ask HN: Does money and idiocy have any correlation?
I've been noticing that the more money a company has, the more successful it becomes, the more dumb it becomes. There are a few exceptions - Apple - but those companies are rare.

What is it with money and market share that causes good companies to all of a sudden turn dumb?

It's getting to the point where I don't want my favorite startup to be a huge success because I'm afraid they will destroy their great product for some reason.
"I've had the misfortune to be in touch with leading authorities (who work with primary data) in the field recently, and most of them DO believe that gluten intolerance is real, prevalent and very serious."

You're just cherry-picking. All of the credible researchers in the field estimate the prevalence of "gluten intolerance" -- at the high end of the spectrum -- to be well under 10%. The guy at the U. Maryland center is on record for a prevalence of ~6%.

I'm sure there are a number of "expert" wackadoos who say that the number is higher, and are happy to sell you a book about it, too.

"There is not agreement about the delayed allergy mechanisms work (mostly IgA and IgG) to the point that there is no standard lab test for them"

Nonsense. There are well-established tests for immunoglobulins to gluten/gliadin, and they're so widely employed that they're in the Merck Manual as part of the diagnostic procedure for Celiac disease.

The situation here is that these test results don't correlate with the self-reported symptoms of people with "gluten intolerance". People who desperately want to blame their low-level health problems on gluten take this to mean that the tests are inadequate; the medical community concludes that the tests are fine, but the "intolerance" (if it exists at all), is not mechanistically related.

Finally, not that it will change your mind, but a Wikipedia article about a diet fad is not a reliable source of unbiased information. If that's your source of "primary data", then you need to find another source, because Wikipedia articles are notorious for cherry-picking extremely questionable, "fishing expedition" studies, and presenting them as consensus. Looking over the page you linked, I see a mess of incoherent speculation, but no one mechanism. Aside from the usual immunological markers of Celiac, there is nothing canonical.

The data pulled from the car indicates Musk has a very biased view of the data pulled from the car. Some of his interpretations are flat-out wrong.

You need a team.

I have the same problem doing things myself. I see the overlapping demographics too, I see the nebulous potential use cases too, I see the end products too, I finish them and then get saddened by the lack of polish or details I could put into it to match competitors.

After spending some time at big corps I came away with a realization: I needed a team to back me up.

Those guys that work at the fancy office parks with the free lunches and bus shuttles to everywhere, they don't work that hard! It's because they have the right amount of people to do the right amount of work on the right amount of things.

I also think of it as a fireteam from my Marine Corps training. When we engage in a firefight we utilize tactics of a lead, advance, backup with fire, lead, advance, backup with fire again, repeat.

You need backup.

The process you've established is correct, you just have to keep using that process to find the right product fit. Then you need to make a go at it, delegating work, polish, market, and sell.
They aren't hard to find, especially because Broder had been to a supercharger station before and didn't have any problems finding it then.
On the third and fourth infractions, the subscriber will likely receive a pop-up notice "asking the subscriber to acknowledge receipt of the alert"

I'm more curious about how this is supposed to work. Is my ISP going to dynamically insert javascript into random webpages? I don't use any of the infrastructure of my ISP, relying on my own email and DNS, so how exactly is this supposed to work?

Maybe altering your IP address to a private block that routes everything to a splash page (a la public wifi where you have to accept the ToS)?
S3 does replication and failover. That's part of its advantage over using a dedicated server running nginx or something.
Thanks for pointing that out, we'll be sure to clarify that on the site!

For now we are currently able to host research that is based at universities, while private or independent research requires more effort to evaluate and vet the proposal on our end. We are working hard to launch more independent projects soon!

I'd love something like this for HN / Reddit / etc -- great work!
So far the people being funded look like they all have jobs at universities in the U.S., in which case, wouldn't the normal IRB process cover these concerns? Typically IRB oversight applies regardless of funding source; even unfunded research has to be IRB-vetted, so I would assume a researcher receiving Microryza funds would also need to ask their IRB to approve the project before it got to the stage of human or animal subjects.

Would be different if they funded independent research organizations which don't already have internal ethics processes in place, but it seems so far they aren't.
I think Ms. Mayer is doing the right thing for Yahoo! at _this_ time.

Yahoo! needs to be in high-contact mode for a time while it gets its company culture sorted out. There is no room for people who aren't willing to commit to full participation in the company and its day-to-day functioning in the highest bandwidth form there is; being present.

This is not a strike at working remotely in general, its Yahoo! dealing with Yahoo!'s issues.
Disclosure: I work on the Redshift team.

The OP's cluster is a 16-node hs1.xlarge cluster (has 3 spindles per node). There's actually a more powerful node-type hs1.8xlarge which has 24 spindles on each node. More info: http://aws.amazon.com/redshift/pricing/

So it's not fair to compare Redshift performance to your Vertica cluster unless the hardware is similar.
Thinking about this stuff is a premature optimization. Portion control and being serious about exercise is easier to comply with than worrying about macros and dubious claims about leptin.
Most elite athletes eat garbage, yet are still fit because they exercise most of the day. Usain Bolt's "power food" is Chicken McNuggets. One can get very far without worrying much about meal composition. It becomes more relevant if you are an advanced bodybuilder or extreme endurance athlete.
Open source projects tend to be almost entirely remote. That’s qualitatively different from a company like Yahoo!, which I imagine to be majority in-office, with some remotes.

From the link you shared (which I strongly agree with):

There’s no halfsies in a distributed team. If even one person on the team is remote, every single person has to start communicating online... no more dropping in to someone’s office to chat, no more rounding people up to make a decision

So the in-office members are forced into contortions to accommodate the remotes. That may be OK if the team is committed to the practice, like stack exchange is. But if Yahoo! is run like a traditional company, designed around in-office work with occasional exceptions made for remotes, then those remotes burden the in-office team members, and absolutely hinder communication.
Yeah, but I wouldn't have installed that on my server, it would have been too awkward and a support challenge for FogCreek. So, I think the idea was to support deployment on a standard runtime for each platform: PHP on Linux, ASP on Windows.
The brake booster on the other hand is parasitic.
Well, this is going to be long :)

We're not worried at all. TravisCI has focussed on making a great product for open source, and we've focussed on making a great product for teams of full-time web developers. They have different needs, and both of us would need a lot more to be able to move into each others' space.

To give you a few examples, they allow you to test your code against different versions of Ruby at the same time, to show your build status on your public GitHub page, to be notified by IRC, and to send build emails to mailing lists. That stuff is great for open source.

By contrast, our features are all designed for your company's web application. We offer first-class support for Continuous Deployment. Our builds are lightning fast to reduce your feedback loop (a customer clocked us at 1m:30s vs 3m:50s). We also support automatic-parallelization to run your tests across multiple machines. We allow you to SSH into our machines to debug your tests. Our emails are personalized so you only get notifications you care about. We allow you to specify the exact patchset of Ruby (we support other langs, this is just an example) that you need.

There are probably some other differences, but basically, we've spent all our time making CI and CD amazing for teams of full-time web developers, and the caliber of our customers shows that: Stripe, Kickstarter, MongoHQ, and Intercom, to name a few who are well respected here. A product that has been honed for open source just doesn't provide the same productivity.

As for Jenkins, well its just not great. Its not a great experience, it allows you to do anything, but doesn't make it easy to do anything. The other part of this is that we wanted to focus on the platform, and Jenkins would have restricted what we could do. By limiting ourselves to a certain subset, we've been able to make the sort of product we described above - tuned to our customers needs. Would have been hard to do otherwise.

Thanks for pointing that out - I've pushed a fix.
Are your F# projects web-based or desktop ones? I'd imagine hand coding UIs to be rather cumbersome.

I had a look around the web, and I couldn't find any sample open source F# applications that one can take apart.
When I made that statement I was think about how there have been blood spatter experts, bit mark experts, bug forensics experts that have all been discovered to frauds and cast doubts on to large swaths of forensics techniques that were accepted in general(by the court and public not always other experts in the field).

That was impressions from remember articles where expertise in the above three fields was tested independently and experts were found to lack predictive power. I would have to search for that articles again if I wanted to provide a reference however I am working from memory.
For quite a while a majority of the US did believe Saddam was directly involved in 9/11 [0]. Although it's a minority opinion now, it's still a quite sizeable minority.
Anecdotally, I remember hearing such claims/speculation in the news frequently just after 9/11, before they moved on to other excuses.

We use Infobright at SnowPlow (https://github.com/snowplow/snowplow), and are currently working on our Redshift integration.

One thing to be aware about with both is the lack of any support for wide tables - Infobright inherits MySQL's limit of 65,535 bytes per row (and UTF8 means 3 bytes per char); with Redshift you can stored wider rows but you can't query them (http://docs.aws.amazon.com/redshift/latest/dg/r_CREATE_TABLE...). Obviously not a deal breaker, but it locks you firmly in the densely populated rows, relational mindset.

This aside, we're super-excited about Redshift!
Prescriptivist peevery (often with weak support) is by this point an HN-Trope.

For example, Musk claims that the author was deliberately driving in circle in a parking lot to run down the battery.

I think more damage was done in this assertion than anything else in the whole drama with the exception of the flatbed. Here is Musk making a big point of travelling half a mile and raising the profile of a minor issue - making people think that half a mile is of considerable importance for the vehicle. 'It's not fair, he (slowly) drove half a mile to kill the battery' translates neatly into 'driving half a mile will kill the battery'
I find the Fed's stance a bit strange. "Just" three months incarcerated and a permanent felony record or try your luck against a 35 year sentence. Meanwhile, the state of Massachusetts was prepared to drop the case entirely as was JStore. Unbelievable.
> Does the informality effect in any way the rationality or defensibility of their choices?

This implicitly calls me a liar. As I stated above, the word choice and informality don't bother me. That they spent so little time thinking if the article would make sense to a random reader does. That goes against my expectations for NPR.
> "it is delivered differently from what seems to be the norm between two men"

As a man, it's hard to deliver praise to women who totally deserve it because of the worry that "she might just think I'm hitting on her" or "she might think I'm saying it out of pity".

Do you have suggestions for how I might give genuine praise that doesn't get misinterpreted as either of those?
We have just crossed 2 billion items in our datastore. While not 3 billion yet, I expect that to happen later this year.

Internet access and cell phones have become effectively needed technology, and so far appear to have been a net benefit. The internet increased the amount of shared data, cell phones increased the sharing and consumption (in the case of smart phones) of data, and Glass will increase the generation of data. What benefits can that extra data have?

Email me if you ever make it to Boulder and I will collect the beer. ;)
You see this pattern of over generalizing in business when expanding internationally service or product offerings. 'It works here so lets just sell it there' has caused a few blunders. Cultural differences can mean colour has different interpretations and that alone can make or break your sales. Some form of product modification is necessary so that you don't get lost in the trap of generalizing.
Integrating TV with Social
Given that it's proven to be incredibly difficult to make any money as an Android manufacturer I'm not surprised to see Sony taking a different tack. Question is whether it was a careful considered move or a desperate bid for something new.
