Great. Also patiently waiting for your website redesign, that way I can browse all campaigns. Are your campaigns limited to 30 day timers?

Whoever has the money and connections to do this but for sneakers (Supra material, Nike material, Converse material, all types-- I will pay 10 extra dollars to put my own logo on my sneakers), I will bow down and I will buy sneakers from you all the time as if you were a virtual post-modern Zumiez. When I take my sneakers off to socially meditate among other all black sneakers a good sneaker tag like the Supra ones, including a logo in the back of the sneakers would save me 10 seconds every day!
They have one of these (non-combo) Dyson airblades in a breastfeeding area in a mall I live near.

It's horrendous - my wife couldn't feed whenever anyone used the blade. So now whenever we go, we put a "do not use - baby is feeding" note on the hand-dryer.

It's not a drop-in replacement for towels or normal air-dryers by any means.
No worries - you're right, I should have said framework. Will look into Sinatra!
GitHub does not really use emojis in the Unicode sense. It's special character sequences that are replaced with an image.
By the look of it the course will basically walk through the creation of a specific game rather than have students create their own.
Apparently, he's not tough enough to run a public company? (Playing devil's advocate.)
Not objecting to the specific idea, but ... I'd prefer to think more about ways to elevate everyone's contribution than just about ways to filter people we perceive to be unhelpful.

(Unfortunately that requires letting go of us-vs.-them, and just speaking for myself, that's surprisingly difficult and ongoing work.)

Elevating everyone's contribution seems to be the thrust of much of the features in Discourse.

Eh, the hits are only a small part of why it's the biggest sport. There are a lot of things the NFL does better than other leagues.

I'd argue the biggest is the salary cap and the parity that results. But there are dozens more, and hits are probably low on the list since they're still nowhere near as exciting as the slam dunks you see on a SportsCenter highlight reel.

I can't resist commenting that, because 2 is the only even prime, this makes it the oddest even number. :)

Paper towels are more hygenic as it turns out that friction after you wash your hands is essential for removing some dirt & germs. The environmental impact of paper towels is minimally worse than air dryers.

http://conversableeconomist.blogspot.com/2012/12/paper-towel...

Also have you ever tried to dry your face with an air dryer? Awkward is not nearly a strong enough term to describe it, let alone if there is someone watching you.
For the Roadster (which is no longer made). The Model S is not related to the Lotus.
Just heard a report on the radio about these kinds of dryers. Excel Dryer, Inc. in Massachusetts was actually the first to sell a high-speed dryer like this (the Xlerator). The Dyson AirBlade came later. Interesting stuff:

http://www.npr.org/2013/02/04/171090394/how-one-company-rein...
I'd be curious to hear if any HN readers are using Sentry and how they like the service. We started as primarily Python based, so it's especially interesting if you're using it for another language/platform.
Am I the only one who hates the AirBlade dryers because they splash me in the face (presumably partially with the water that's been pooling in crevice along the bottom if it's being heavily used)?
Unlock the value of information: share it
Cloud makes it quicker and cheaper, mobile de-localizes data, social technologies create an environment for information sharing and innovation. But the real gain is when the hidden value of information is unlocked.
If you care what the number actually is, and you have gnu bc, :
echo '(2^57885161)-1' | bc > prime.txt

will yield a text file of 17,937,675 bytes, containing all the digits of the number, plus some overhead for newlines and continuation.

This is still a friggin popularity contest. Why do communities need to have any sort of popularity metric attached to each comment (favorites, upvotes, etc)? There are sites that are meant for this (hacker news), but that doesn't mean the methods are generally applicable or even desirable.
I'd imagine there's a market for a generic push-button "insert dev-provided VM, recieve app" hosting service for these kind of people without being limited to PHP. AWS Marketplace already does this to a degree, just a matter of making a similar service accessible to the GoDaddy crowd.

I accept both of those points. I was asking in the context of safety-critical systems. I see no advantages of goto over a function call.
The fact that you have to wear armor to play a contact sport games shows the quality of the game. I watch only the superbowl every year and it tells me why I don't watch the rest of the year. Soccer is just such a nicer sport. The worst that can happen is a leg injury, not cumulative dementia.

Firebase is useful here because you can use it to handle state changes for iceCandidates and not worry about using your own server. You can also store data with Firebase API. By 'serverless', OP means that you don't need to have your own server/database and can host your app as a standalone html file, letting firebase take care of your backend.
There's a pretty substantial amount of financial guidance available to pro athletes. I keep seeing this mentioned here but it's just wrong. They aren't broke because there's nobody telling them "hey don't blow all your money." Every team in every sport has an orientation for new players, and nearly every major sport athlete has an agent with an MBA.

They're broke because they spend it anyway. You can lead a horse to water but you can't make it drink. Many of them come from the sorts of backgrounds where you spend the money when you've got it, so that's what they do. But they've all been advised differently.
Just a tiny FYI, We occasionally buy billboards at discounted rates, but not near $100K. We have one up right now that cost about $8,000 on the 101 in San Francisco. Sounds like you've seen it!

Ask HN: How should one teach high schoolers to code?
Hello, Hacker News. I'm a high school student in Portland, Oregon and I have volunteered to setup a programming course in my high school to help bring course diversity to the public school system and bring better opportunities to young people.

Treehouse (http://teamtreehouse.com) is sponsoring the class of 15 or so students and each student will have a Treehouse membership for free they can use to study at home. I've been programming both front-end and backend web development for about 5 years now, but have no teaching experience.

My question to you is, how should I tackle teaching programming & app design (HTML, CSS, JavaScript, Ruby, Objective-C) to students who know nothing about it in a short 4 months?
Isn't that what karma thresholds are for on HN?

Not only does it run the latest stable release of Rails 3.2 (which was immune from the latest security vunerability), but I made sure we are running the latest versions of all Rubygems.

Having said that, this is very much an early beta right now. We expect to get a lot of feedback over the next little while, and we want to integrate that before we release a 1.0 stable that we'd be comfortable telling many people to install.

If you install it now, you'll have a more complicated upgrade path to our 1.0.
Not yet mobile is the last crowd we're supporting. Our application is people that are going to die. You get me?
> It's the risk and conscious choice

On the contrary: players, teams and the whole league have hidden the extent of injuries before. They used to just load the players up with painkillers and send them back out. They had no idea how injured they were. The NFL has been criticized for lack of disclosure regarding brain injuries for a long time. "As of December 2012, thirty-three former National Football League (NFL) players have been diagnosed post-mortem with CTE." https://en.wikipedia.org/wiki/Chronic_traumatic_encephalopat... These players had no idea how injured they were. "In 2012, some four thousand former NFL players have joined civil lawsuits against the League, seeking damages over the League’s failure to protect players from concussions".

I don't really understand this, we just stick it on our app/db servers alongside our other applications. The cost is $0 and it takes about 5 mins to set up, it's just a Django app.

Those who don't learn from Usenet are doomed to recreate it -- badly.

My ideal discussion forum software would support threading, would remember which messages I've read and which I haven't, would allow me to rate both messages and authors, would provide a personal killfile, and would allow me to use whatever client I prefer to access it. In short, it would be Usenet exposed via a web API. No discussion forum software I've seen so far comes even close in features and usability to what GNUS provided in the 1990s.
Pocket is in far wider use, and thus seems like a natural addition. Pinboard, although a relatively unknown service, would also be appreciated.
Very cool. With Frank, Calabash and Zucchini already out there (to name just a few), the iOS UI automation space is getting pretty crowded. Having said that, it is definitely nice to see something that is not based on Cucumber. Any ETA on the Android?
I wish I was a programmer so I could build one and just fly it around. I know that's not the purpose and it specifically says it's not for toying around, but with a camera I think this is really cool. Who wants to make one for me for an additional cost? :)
I find that the Xlerator takes far longer than old fashioned paper towels or the Airblade. It's also painfully loud.

It may be far better than the awful standard hand dryers, but it's not perfect.
why is the propeller chassis made from circuit board? Isn't that kind of an expensive and fragile solution?
> StackOverflow also has an extremely busy design, and it seems to work.

People often make the argument about HN being ugly and hard-to-use vs. those who think it is perfect for what it does (even saying that making it simpler would make it too easy for non-technical people to get involved, which always confused me). Personally, I think all three of these services could be much cleaner and user-friendly without Fisher-Pricing it.
Mind noting which service? We're a New Relic customer but oh yeah, frigging expensive.
On a naive per-mile basis, for short trips, electric cars kill gasoline powered ones. The "fuel" cost for overnight charging is approaching the golden age of $1/gallon. The real question is TCO. Whoever has the better TCO in the long run is going to win, and electric cars have some strong fundamental advantages in their favor here. The biggest stumbling block is the battery. A 40% improvement in TCO of batteries for electric vehicles seems likely, and would enable near future electric vehicles to be competitive on a TCO basis. I'm limited to short trips, but my vehicle becomes maintenance-free? Sold!
Four Hours of Concentration
True on the walls and the water pool. Not true on the drying faster. The sheet of air is much more efficient than the xlcerator.
Looks like a good book. An Amazon review mentions that Ely reasons one-man-one-vote as the fundamental guiding principal for apportionment. Have you read that part yet? I guess the Senate gets an exemption...
It does, but the trust metric we use is not very visible on the surface. Which is sort of by design. There is a hint of it on the user page if you know where to look! :)

Probably the main visible entry point is flagging, so try flagging a post or topic.

It's also hard to see the moderation functions from the outside, but I assure you that they're as frictionless as we could make them! For example, multi-selecting posts, splitting topics, merging topics, locking topics, archiving topics, etc.

There's still a lot to do, we have no way of selecting multiple topics at the moment, for example. But I encourage you to try out the Vagrant image if you want to hack on Discourse quickly. It includes a small db, and you'll be a moderator there.
That's overly reductionistic. We're not paying to watch them strike eachother in the head with baseball bats. We're paying them for an intense display of athletic skill, which incidentally is also extremely risky and likely to cause long-term harm. The reality is bad enough without overstating your case or taking a naive view of what people are getting out of spectating.
The constant pauses of the game have made it perfect for television--a huge part of its success and visibility.
This is brilliant. I can't stop wondering how this will make espionage much more easy. Or even stalking.

Then, we will have a slew of companies that guarantee 'security from aerial surveillance'. I'm sure they'll make a killing.

> A typical one- or two-year pro isn't getting set for life

Do typical pros only play one to two years? Also, I thought the harm done was proportional to the duration of play.

Also, let's face it, how much they're rewarded versus the wealth of the promoters has only has a little bit to do with the question. MMA boxers mostly pay IN to the system, except the very best. What's far more important are that the risks are communicated fairly and that everyone be given a free choice to participate or not.

There is a "best of" view in Discourse. It only kicks in when a topic gets to a certain size and we have enough signal to infer the best post.

Thought experiment: how does one quantify the 'best' posts on a discussion topic? Discourse has some ideas about this, and I bet you do too.

"requiring an intermediate exchange that is on a accessible server"

Exactly. So the onus of security is pushed off solely onto the centralized intermediary. In my example it's the Skype servers.

They can very easily firewall and filter all the connections. They can have a much stricter filter then what you have on your computer. (ex: packets have to very strictly conform to a certain standard generated by the client side program)

Centralized servers are also more secure because you don't have any access to the server code and it becomes virtually impossible to look for exploits.

Also if any bug IS found, then patching it is trivial b/c it's at one central point. If worse comes to worst you just shut down the server and now all your clients are safe.
League minimum is $390k (which can only be paid to rookies, it then goes up every year) and the average career is about 6 years, so really the vast majority are doing more than a million gross (and net) in their career.

Also the average salary is about $2m so you're looking at $12m gross. There's certainly a power law there, but still, an average salary of $12m careerwise is substantial.
Maybe because Javascript achieved that growth and subsequent ubiquity not on its technical merits but because and only because it was the de facto language of the web (and still is to this day for a reason that still eludes me).

Funny how the number of languages a programmer can pick from is growing every day, but on the one HUGE platform that is the web, it's Javascript or nothing. And by funny, I really mean extremely annoying and a severe regression.
> This is a similar to the argument people make about HN being ugly and hard-to-use vs. those who think it is perfect for what it does.

Apropos, my favorite suggestion for improvement in HN would be a menu item that lists direct replies to one's posts (something that Reddit does). Without this feature, some HN threads just expire because it becomes too difficult to follow them as time passes.

The article isn't about concussions. It's about hits that do not cause one to show visible mental effects, but are in fact a very mild form of concussion (TBI). And it's about players thousands upon thousands of those hits throughout their life.

Can't say any more than that it works for us – we compile Apache ourself though for various reasons. But according to the link above it should work.
And yet it happens anyway. I saw at least one instance during Sunday's game.
It quickly becomes expensive if you're routinely sending a measurable amount data to it.

Disqus has two physical servers dedicated to it. Both of them are larger than any of the web/worker machines getsentry.com runs. On top of those costs, they also have the upkeep cost of running those servers, doing software upgrades, and, if anything goes wrong, debugging things.

Obviously Disqus isn't a great example, since we built the software and know how to run it, but companies much smaller than Disqus don't really have the reason to invest the money or time into setting up infrastructure to support it.

Delicious is using Sentry on their new JavaScript-centric site, and for the amount of data they're sending, they'd be spending a lot more on hosting costs and infrastructure maintenance. It's not ideal for everyone (some companies push a lot of data through Sentry), and we don't necessarily aim to serve someone who may be sending millions of events in a day.

What we typically see is that most people are sending somewhere between 5,000 and 50,000 events, which is right about the size where it's not practical to host the instance yourself. It definitely beats maintaining RabbitMQ, Redis, Memcache, Celery, WSGI, Postgres, and soon, Elastic Search.
He did some questionable things, true. He's not a saint, true as well. But then again, name ONE great entrepreneur that never did any shady stuff...

And at least he's not hoarding the money like other CEO douchebags and doing what he thinks is best for mankind. I like to think that's commendable.
Social Skills Boot Camp Interest Survey
Go's support for first-class functions definitely sparked my interest in the language. But one thing that Javascript, Python and Ruby programmers would expect of higher order function support is the ability to use the general collection methods such as map, reduce, filter (or inject, collect, fold - whatever they are called in your language). So far as I can tell, generalized functions of these types are not really possible. You could write some that were typed interface{} and then did explicit casts in the closures you passed, but that would not be nearly as elegant as what other languages provide. I believe in a static type system without generics this is not really possible, and this is really (to me) the most painful cost from the lack of generic support.
On Debian, the standard packaging system is APT, and it is more work to install software from alternative sources than it is to run `apt-get install`. Is Debian a walled garden? Why or why not?

I'm surprised that he compared forums to stackexchange and the customer service sites (uservoice, desk, etc), but didn't mention Quora.

A lot of the moderation stuff and trust metrics isn't visible on the surface. And to be honest, we've only implemented the first two (new user, not-new user) and final (appointed moderator) trust levels at the moment.

One way to think of this is as follows: what happens when posts get flagged? What's the sequence, who knows about it, and how? For that matter, who can flag?

We do have basic rate limits throughout the app, and they're all configurable as well.

Much of this has to evolve. I'd love your input on it, too!
