Congrats on meeting your goals!
Its nice to see another shop switching to Scala. I have been advocating the same change where I work ( currently PHP and really feeling the pinch of what it can do ). Looks like I now have another data point to use as a success story for transitioning away.
>line-of-sight quad-copters that can stay up for 20 minutes

10 minutes is the median, but they don't have to be line of sight, except as bound by regulation such as in the UK [0]. Still short-range though, and certainly not suitable for this use-case.

Some of these design blogs need to be put in the same bucket as W3Schools on HN so people know not to bother. So much misinformation.
Terribly misleading marketing blurb.

If I read this right then this is not a tool that you can download but a SaaS-addon that works only on one fairly obscure cloud-platform (openhosting.com).

Too bad, I'd happily pay a license fee for a capable OSS(!) Toolchain that integrates well with chef/puppet and any cloud. This is an area that would greatly benefit from standardization - currently everyone rolls their own.

But at that point it becomes a UX issue. There's only so much space on a printed menu. Calories are an easy to print, single data point.
You can understand what sexism is while also acknowledging that there are extremists in every group. I can already picture a few such extremists calling this title sexist.
Recently the places I've lived have all had calorie counts on menus. It's very helpful. That way, when presented with a choice between a 400 calorie meal for $10 and a 1200 calorie meal for $10, I know which one will give me more calorie for my buck.

Yes, some of us use it to get more calories, not less. It's just far too helpful to know exactly how many calories you're getting. It's not just for people dieting or wanting to eat less.
The very definition of monopoly is that there is no alternative. I can't just go to another company because they, for instance, do not have the people I'd like to connect with in their network.

>Yes, he is trolling HN with the title, because you can get sadly predictable conversations like this one.

The article was published on the 37signals blog. I doubt DHH considers HN the center of the tech universe, given anecdotes of his general disposition I can't imagine him thinking "just wait until the HN crowd gets a load of this title".
That's essentially my beef with most query objects. Wrapping a query in an object like that is usually too much ceremony for something that's just a method.

It doesn't get any better by having Viewer.new(current_account.posts, current_user).visibles or #execute or whatever else you'd do in a query object.

I'm just a participant here, and am not associated with YCombinator in any way, this this is just my observations ...

I've gone to look at that post and I can't see why that would cause you to be banned or otherwise have sanctions against you. It appears to me that any bans will have been provoked by some other behavior. The automatic systems of HN are well-known to have the occasional (and more frequent) false positives. I don't understand why you might specifically think it's that particular essay that got you banned.

It says in the guidelines:

Please don't post on HN to ask or tell us something

ask or complain about moderation). If you want to say

"Estimates for fast food calories were significantly misguided – but in both directions! Apparently we have been misled by those oh-so-catchy jingles."

So, the short answer is: Yes.
No,because technically if I run a server in the US, and a german user connects to my website, I should not be bothered by the german laws,and there is nothing the German government can make me do with my website. If they don't like their citizens accessing my server,they can block it inside their national network, but saying that I should conform to their laws is preposterous. I imagine that everyone happily complies with Saudi Arabia's requests to remove pictures of women driving, from every single website on the Internet, because that violates their laws. Internet does not know boarders - I run a server, if you want to access it from within your country - cool,but I am not going to bother with your country's laws,because it wouldn't make any sense to do so.
I wonder what would happen if you designed the page a little bit differently, and gave them an option to pay, and a separate option to download it for free.

At first glance I want to put in $0.00 just to see if it works, not necessarily because that's what I'd be willing to pay.
Apple in Talks With Foursquare About Data-Sharing Deal
Maybe that is what happened. Although he seemed to be in bad health before being accused. Many people don't care what others think about them. Hopefully Ryan Lanza is or can become one of them.
Interesting. I was just looking for a Postgres as a service this morning. I decided to go with https://postgres.heroku.com
> As I understand it, "identified by law enforcement" was some guy in the Connecticut State Police talking to the media without authorization.

I don't see how somebody from the state police, talking to the media, saying "Ryan Lanza is the name on the driver's license" does not constitute being "identified by law enforcement".

It may have been "erroneously identified by law enforcement" but that does not make "identified by law enforcement" a false statement, no matter how much you want it to be.
PHP probably gets in there somewhere. (I looked up the history -- I did not know that PHP was first implemented in Perl.)

PHP was first created in 1994, so it's 18.
The solar-powered bike-car thingy we’ve all been waiting for
I work for a social game company that was bought by one of the largest entertainment companies in the world a few years ago. When I was hired, I did web programming (mostly social integration with facebook). I've since transitioned to game client and backend programming, first with flash and java, then with c# (Unity 3d) and java. No node.js for us, it's not nearly performant enough for our purposes. We use java on the backend due to ease of deployment and reliability. I want see how one of our games does with an erlang backend, but I doubt our data center guys want to support another stack.
I've never started a project on Kickstarter, but it seems like it would be good for them to offer materials, guides, and potentially a mentor network for entrepreneurs. Maybe even going as far as explicitly walking new applicants through a business guide before they can submit their project.
Slate has been around for a while, and has some interesting concepts (prototype and multi-dispatch).

The brains behind it seems to have lost interest years ago, and the "Jobs" behind it has a major personality disorder that just turns people off.
How Raising $291k On Kickstarter Nearly Killed An Underwear Startup
I haven't, but mainly because I don't have the necessary space/facilities to work with CF. I live in an apartment and don't really have space to make a CF-safe work zone (somewhere to contain the dust, keep my dog from eating the epoxy, etc). Ditto to a proper vacuum bagging setup [1]. I agree that CF is probably the ideal composite.

I'm working mostly with wet-layup fiberglass cloth and sandwich panel constructions, as well as some semi-silly experiments with glue/paper/fiberglass. Also exploring some designs that use tension cables to support the load. Lots of fun, if not entirely fruitful so far

[1] I could probably find space for a vacuum bagging setup...but my girlfriend barely tolerates all the stuff as it is. Best not to push my luck :)

The most important fact that could possibly be presented, and it's not presented.

Signal to noise ratio is basically nonexistent.
Wow, that was not entirely unexpected, but rather poorly executed. I would have hoped there would be a grace period were you could either remove material or mark it in such a way that it wasn't tagged with this right.
Very interesting analysis. I am in no part discouting what you say, but i for one would like to see the OEM's push this increase in efficiency.

Obviously when it comes to battery life there are a million and one different factors, but considering a mobile devices usefulness is directly related to its ability to run(have battery) you would think this would be a more focused area. I mean i know most people are happy with a full days charge but i dont think it would be outlandish to say that the majority of phones limp in one 1 days use. Battery life has decreased over the years not increased.

My comment of "1/6 the battery usage" was more to if it has 6x the power does it use 6x the energy?
Hatch: the app that loves you back
Yup, I'm in this boat! I regularly use the calorie count to maximize my Cal/$. I have a hard time keeping weight on.

Should I just delete this? Not worth the space and/or time?
Surprised to see many of your are into philosophy--that's pretty awesome!

@Biofox: Thanks for that link. I'm gonna be checking that out in detail.
Living in NYC I've definitely appreciated seeing the number of calories on the menu; I'd like to see it everywhere and not just chains.

I'm much more likely to order something with a lower amount of calories. If there are three choices: 400, 600, and 800 calories, I'll pick the middle and feel better about the choice. I now know that a large combo meal at McDonalds is easily 3/4 of what my daily intake would be.

Secondly, it shows up the hidden calories. How many people realize that the 20oz of soda with their meal adds an addition 200-250 calories? Or that an venti eggnog latte at Starbucks is a scary 610 calories.

I think restaurants are a big culprit. You have no idea how good or bad the food you are ordering is.
Really? Seriously?

"StudiVZ" was a lame (and, if I remember correctly, bit-by-bit when they started) clone of FB, which won here for a while. Probably because they actually had a local interface and added local universities, schools and whatnot. Since then FB expanded to Germany, StudiVZ is for all purposes dead and obsolete.

I don't even know how you come up with that example. It's like pointing to Myspace or whatever came before that.
Agreed. SEOP was one of the best resources I made use of as an undergrad
I wouldn't necessarily say they are connected, but they could be. If lawmakers change the tax code to increase the tax burden then it's possible they will introduce new loopholes. The Federal tax system is incredibly complicated and sometimes it seems that just reading the table of contents causes new loopholes to magically appear. Often times I think that simplifying the tax code would result in higher revenue even if you lowered the percentage on each bracket.
At Instagram, the backend, API and web applications are built using Python/Django but not mobile applications. They are made with native ios/android technologies.
Fixing our social sharing tools
Quantity, price, administrative overhead, and dynamic creation all played into it.
Could equally apply to any app on the Apple market place. Yet for some strange reason people actually pay to develop on that platform.
If only Android let you one-click share to any social network you wanted and included all of the photo manipulation and filter features of Instagram. Oh wait.
What is the purpose of calorie counting for humans exactly? Most people don't get fat/slim/strong/weak because they ate too much/too little [calories]. It's what you eat.
Well.. That's a workaround, not a true solution.. that takes away our mouse cursor strength...
I don't get what the issue is, I don't even know Perl and it seems pretty straightforward to me: Carp is a library with a set of mnemonic assertion functions for libraries to signal usage errors committed by their callers.

Do people just prefer one function with a bunch of fiddly little enums or something?
It depends on the use. If you are using the photos for news purposes, then yes, this works. But if you are using it for commercial purposes, then you would also need a release showing that the person (celebrity or not) received sufficient compensation for the use of their likeness. Without that, you can be sued very easily.

This example is using box2d for something that can be implemented with very simple code dropping this important dependency IMHO. Box2d is a great fit when real 2D physics simulation is needed, but for apples falling at constant speed and jumps, it's not worth it.

If that is the only way, then the conclusion is obvious.
You don't need to be an extremist to call the title sexist. DHH is well known presenting the persona of a dick.
Ask a random sample of engineers what "chubby models" refers to, and if less than half think of fashion models, I'll be greatly surprised. IMHO it's the most sensible semantic binding.

As for your characterization of dccoolgai's actions as being a "white knight": take your polarizing term back to reddit. Inaction in the face of speech that marginalizes a certain group only furthers that marginalization.

Also, dccoolgai, why did you leap directly to women's body issues? There are make models with body issues as well.
How is this trolling?!?!?

In Rails world, the topic of fat models (lots of impl methods, code, etc) comes up all the time. This isn't trolling. It's called being creative vs. "Use different code to remove more code from your models".

Gimmie a break..

And yes, like another poster said, I doubt DHH uses any thought or loses sleep over how HN will pick up the post and tear it down. He created a great framework, has built up an inspiring company, and wanted to share some thoughts. Doesn't go any further than that in my mind.
It sounds like you knew it was bad practice, and yet you did it anyways...?
Hehe...yeah...

They are mostly safe, you just have to treat them nicely. Improper charging is the biggest risk, so as long as you charge slowly with a proper balance charger there is basically zero risk. It takes longer, sure, but I'd rather charge at 2C and not burn my house down than charge at 10C and play LiPo roulette. I charge and store my batteries in a flame-proof LiPo bag, and will be getting a fireproof safebox soon.

A lot of people will fast-charge when they are outside charging from a car battery or something, so it's less of a big deal if it explodes (since you should be charging it on a concrete block or something away from people).

Over-draining isn't really a problem, since even cheap ESCs have over-drain protection and won't let you drain the battery. I don't think explosions are a problem when you over-drain anyway...you just permanently damage the battery.

Otherwise, the only thing you really have to worry about are crashes. After a good crash, check your batteries to make sure they are uninjured. If they look a little deformed, best to play it safe and store them somewhere safe (bucket of sand, metal box, etc) for a few days to see if they get puffy.

Puffy == dangerous, discharge safely and dispose.
Like I said, Slate has some cool concepts in its core, but nobody seems interested. Someone with too much time on his hands could write an awesome Smalltalk-like environment around it.

I don't think I'll trust the results of this. It sounds too much like they found an "independent" group to study it, and then pressure them into giving them the results they want.

I would've rather seen an independent group take the initiative themselves and ask TSA to let them do the testing, at least.
Common Lisp is 28, which a year younger than C++ and not much older than Perl. So not a dinosaur language as some people think. <g>
yes, on it!
G+ has more active users than Instagram based on the released data. They purposefully don't release too much information, but the figures that have been announced show G+ to be far larger than Instagram. Instagram claims more than 100M signups, Google claims more than 500M. I don't see MAU for Instagram, but Google+'s MAU is 135M which is more than all of Instagram's signups.

Like any social network, what you see is dependent on who you are and how you use the service. Instagram is much more wide open than G+ as well, people are much more likely to share content to only a few people on G+ and thus you'll never see that content (or any replies). From what I've heard from photographers, G+ is definitely an active place to share photos.
You can choose not to social network if Facebook is the only social network. That is clearly an "alternative".
The current version of the TOS say, in part:

When you upload or otherwise submit content to our Services, you give Google (and those we work with) a worldwide license to use, host, store, reproduce, modify, create derivative works (such as those resulting from translations, adaptations or other changes we make so that your content works better with our Services), communicate, publish, publicly perform, publicly display and distribute such content. The rights you grant in this license are for the limited purpose of operating, promoting, and improving our Services, and to develop new ones.

IANAL, but I don't think that includes a right to sell (sub-license) your content.

Microsoft was (is!) a monopoly. Although you can buy OS X, get Linux, FreeBSD, OpenBSD, NetBSD, Nexenta, SmartOS, Solaris, Haiku-OS or whatever floats your boat. [1]

Facebook is a monopoly, even if there are products/services available that provide something kind-of, sort-of similar.

That sounds like a great idea and I've been looking for something similar to try and lose weight. But if you eat out a lot and the calorie count is not written on the menue, how are you going to record it? For example, if you order chicken with rice, that may be a fairly healthy choice except if there's to much cream and butter in the sauce.

Eating healthy definitely is hard. Also can you link to the app? My google-fu is failing me.
My professional work has nothing to do with web dev/apps etc. I only do this as my own personal hobby (and in the hopes of building something useful). I work as a tech. BA/dev (role switching) in investment banking industry and deal primarily C++, perl, python etc. I have seen light web work when I was indirectly supporting E-commerce team which involve a bit of the web goodies.
If they didn't have so much money then the reason would have been that they were strapped for capital.

The nature of successful Kickstarter projects is that they are are solving hard problems. Hard problems are very difficult to estimate and the cost of being wrong on your time estimate is very low. So why would anyone not just provide an optimistic delivery date?

"A discussion between the planets" Written with websockets during charity event
I can't answer your question completely and I'm by no means a legal expert, but I know that German law states that you have to abide by German laws if you website is targeting visitors/customers living in Germany, even if you aren't German yourself.

Short example: An American hosting a personal WW2 website in the US with a huge German user-base has a good chance of getting in trouble in Germany if he denies the existence of the holocaust on it.

It took quite a while to dig up some facts about this topic, but take a look at http://juris.bundesgerichtshof.de/cgi-bin/rechtsprechung/doc... (in German, but can be translated with Google translate). According to that article our BGH thinks that the New York Times has to take down defamatory statements about a German/Spanish resident that went to court in Germany if they don't want to break German law. Further down they even add the fact that the NYT had ~15,000 registered German users back then to solidify the claim that the NYT is targeted at a German audience. IMO this shows that some connection to German residents has to exist for German law to be concerned. From what I know, a German telephone number or offering a German translation of a website might suffice for this connection to be made, too.

On another note: I have not found any case where an extradition to Germany took place, but I have heard of non-internet-cases where people got into trouble when they traveled to Germany.
Technically, even if you are targeting old browsers, you don't need jQuery; it's written in Javascript, after all. There's nothing they do that you can't do with vanilla JS.

We have rights to life and liberty, and the right to private ownership of weapons acknowledged in the 2nd Amendment is an instrumentality to help ensure that. It should also be noted that the Bill of Rights (1st though 10 Amendments) were a price demanded by the Anti-Federalists for accepting the Constitution.
