I have been building a (highly accurate) flight simulator.

Basically, I'm taking a geometric approach to the flight dynamics model (similar to how x-plane works, except they're using... older techniques/technology. I'm using much more advanced stuff [working on seeing if I can simulate the airflow for the entire craft, as opposed to doing it by sections and then integrating those together]). This is in contrast to things like MS Flight simulator and FlightGear (though, flightgear does have a poorly documented and rather inaccurate geometry based fdm - but most people use the table-based one, which is far more accurate than the geometry-based fdm they have implemented), which use lookup tables to guess how an aircraft would perform.

The problem I actually originally set out to solve was that xfoil and xflr5 suck to use (importing/exporting plane data is... either you can't, or you shouldn't), and fuck paying for the more expensive design testers. (this is why I have the focus on accuracy - if this was just going to be a simple game, I'd have spent far more time making it look pretty) However, I figured that I could also make testing be more fun by adding an interactive mode (i.e. I want to be able to do hardware-in-the-loop type stuff, as well as just manually flying), and at that point, it just is a scriptable flight simulator.

I'm still working on the flight dynamics model, been teaching myself fluid dynamics so that I somewhat understand what all is going on there (as much as anyone who hasn't spent years studying this can understand...), and I've been working on writing code to run on the gpu (yay, opencl) in order to do this. It's been fun.
ah, it's because I think that I've see the .php exntesion somewhere
I think he mentions port knocking precisely because he DOES understand point #1 ( the difference between security through obscurity as a layer but not your only layer), and is giving an example of using it as one such layer.
An informative article, which is worth reading, but the conclusions seem bizarre and lacking in logic.

Why should perhaps the best education system in the world pull back into a period of decompression? South Korea have created a generation of talent which is internationally competitive and fuelling a strong economy. Human capital is now one of the country's best assets. Even if you could identify an obvious cause, you certainly shouldn't seek to mess that up.

Why should the chaebol, who monopolise industry talent, be required to do the same in other industries?
They're asking people to revoke Buffer as an app: https://www.facebook.com/bufferapp/posts/566007046805080

Brutal. Once you revoke it, there's little to no chance that you're going to re-invoke it.

I've seen stuff like this get ugly in the past [1] -- I really like and respect the Buffer founders and hope they can recover from this.

Thank you for the feedback! We're rolling out our models as we acquire customers for our B2B product, and we have none in Portland yet, but hopefully it's only a matter of time.

Sorry about the performance issues, I will be looking into them right away.
If you aren't liking what you're doing, pick something else up. Go try out a different hobby, get into painting, cooking, meditating, whatever. Don't burn yourself out grinding teeth on something you don't enjoy doing. Make sure you enjoy what you're doing. Go on a vacation to a state park, take a break for a while.

> It's not a good thing. Only a handful of nations are capable of producing weaponized drones

A nation spends money on defense for precisely this reason, to produce an asymmetry in that's nation's capabilities compared to all others. It's an explicit design goal! Your argument can be applied to all new technology being developed for defense in all countries-- consequently, I don't think you'll find much support for this line of argument.
I've built GifIt (http://gifit.nodejitsu.com/) this week. It allows you to add a gif with your tweets.

It's cool because:

- Gifs are cool

- It uses getUserMedia() to capture the gif from the browser

- Coded in node.js with the MEAN boilerplate (https://github.com/linnovate/mean)

- It's a 15-hours one-person project
Even better, Google and the automaker's could get into the market of managing fleets and their own insurance directly or via wholly owned subsidiaries. That's what I would do if I were in their position. Basically, this is going to completely disrupt the auto insurance industry as well and no one has more and better data to price the insurance than Google that now has hundreds of thousands of miles logged and will always be in possession of the sum total of all data on all miles ever driven. They are no longer performing statistics on a sample size, but are instead doing so based on an entire population.

Basically Google can do the same for auto insurance that Amazon has done for online retail. i.e. they can operate on razor thin margins that no one else will ever be able to match because they'll be operating on sample-based statistics and it will take them a while before they have a significantly large sample to properly price their product.
That's a grotesque oversimplification and decontextualization of the administration's position. Every administration has considered itself able to "kill Americans without trial" (a) on foreign soil, (b) during hostilities, (c) when the target has allied itself with an adversary. American citizens fought along the Nazis and could not expect due process from Allied machine guns. Similarly, every American police force considers itself able to kill American citizens without trial, when those Americans are threatening deadly force in such a way that killing them is the most certain way to save lives.

Your quote about the NSA has nothing to do with criminal evidence.

Really like the folks at Buffer, hope they're able to resolve the immediate, solve for the future and that neither they nor those who's feeds were compromised suffer too much as a result.
No, they just temporarily disabled their FB app. Once they re-enable, the posts should reappear...
I suppose you are simply trolling, otherwise a simple programming language history lesson will show you that one of the first compiled languages, Fortran, has one based indexes.
The executive branch willfully fails to enforce many laws passed by Congress as well as breaking clear restrictions on it imposed by that body and the Constitution. I would not presume to know the President's mind and will suggest that you do not either, but his actions and track record are fairly clear. I know he was elected by many with the hope that he would end the ludicrously named "War on Terror", but it simply hasn't come to fruition. I would hope that after almost 5 years of this behavior we would cease pinning our hopes on the President.
All the dirt of PHP and Perl + antipatterns in examples.
I'm confused about this one. Wouldn't it be cheaper to use a solution like Twilio to do all this?

b). Sizes are never consistent and a number cannot define a unique bodily shape.

Our solution: We simply send an email with a few complete looks every few weeks, if you like a look - order it and we make it made to measure for you. We ship globally for free. Each look is about $150-$175 (so won't break your bank account). Each look is based off of heavy research around looks, textures and trends that are currently in.

This is really, really excellent. I'll be learning a new song or two today.
"stealth edit"

Oh go fuck yourself. I saw an utterly garbage argument, I responded quickly, then I edited it because my first draft had unhelpful content. "stealth edit" implies a perniciousness that simply wasn't present.

> I don't think you should insult or speculate on the character and profession of other posters

And I think that if somebody says that soldiers have no blame for war, that they're idiots, and it's ludicrous to pretend respect for them.

Why We Should Legalize Murder for Hire
Hey, thanks for the feedback.

As for ATMEGA328P-PU-ND, did you try using the optimization slider? :) Drag it all the way to its "Aggressive" setting, it will bump the quantity up to 25, and the total down to $48 - just like you said.

As for package deals - you are right, this is what needs to be done. We're thinking about that.
We are working on HNWatcher.com, a tool for everyone (community managers, growth hackers, devs, devops...) to track keywords and users on Hacker News.

It is cool because you can be alerted on:

- any mention of your name, company, product or competitors on Hacker News and join the conversation.

- any submissions or comments of users you like

This way you can upvote while it's still time and join conversations on subjects that matter to you.

Student game world takes historic London maps into 3D space
Backed. Eager to see innovation in the sitting market. When I worked for ITA Software we had an ergonomic consultant available, and it took half a dozen chairs until we found one that worked for me. After I left I tried without the chair for a few months, and back pain persisted. Ended up buying the chair ( http://lx.tc/chair - note: Amazon referral link ) for myself, and things have been pretty good since.

But I still believe things can be better. I see colleagues struggle, going between standing desks, different chairs, seeing massage therapists. As a nation many jobs are shifting to knowledge-based work, and people are spending more time in chairs. We can't leave everyone with back problems as a result.

Even if this ends up not being the ultimate solution, I think its great to see work and innovation to move things along and encourage others to spend time looking for answers.
Holy shit, that is awesome! If only I had 55k to spend on that sort of thing, I'd buy it in a heartbeat.
Is there a club for this sort of activity?
Yeah, I might be late to the party here, but... I signed up for penflip two and a half hours ago and have received eight emails from you guys since then. This is not cool. I don't care if they're notifications. Auto-on is a terrible default from a user experience stand point in this case.

Edit: Also, I can't easily find where to turn them on or off, and if its available I'm having difficulty figuring out how to delete my account.

Edit 2: Done being blinded email rage, I located the notifications control panel which is relatively obvious (so facepalm for me there), however, having searched the site it does not appear as easy to delete my account altogether.
You should add a demo or something - that landing page is a bit ominous, and I don't really want to sign up for something that I haven't seen yet.
"You can rent a 3 bedroom house for £300/month in Yorkshire."

Leeds? York? I suspect not.

Bear in mind that single bedroom flats are mainly built in areas where land is expensive, because it is only then that the small space saving over a 2 bed flat outweighs the similar building cost.

Birmingham: 3 bed house commercial, way outside city, is £750 pcm. That will increase when H2S happens (if it does).
Thanks for pointing this out. I do need more copy there stating exactly what the system will do.

In case you didn't catch my response to someone else, the "social etiquette" on each social media channel is different to begin a conversation. For Twitter, it can be as simple as a "favorite".
Chastity? What planet are you on?

LOOKS ARE WHY WOMEN WEAR MAKEUP and mini skirts. If chastity were their test they would be doing exactly the opposite.

You're not getting turned on by porn because the woman is 'chaste'. You're getting turned on becuase she is HOT.

Looks, indicate fertility and health, and are widely know through out all of biology and the animal kingdom to be used by males to select fit mates no matter slutty and how many litters of animals the female has had.
It indicates genetic fitness.

For men success is the test. It indicates accumulation of resources and ability to survive.

Plus, sex is a powerful primitive desire and no (matter what they tell you) they're all "bicycles" as you describe it, just like you would LIKE to be.
I'm curious, what's the reasoning? This seems really really strange to me. My experience has been that female roommates have done the least amount of damage to any apartment I've shared.
Awesome, good luck! Are you doing it with a program or going solo? Do they have access to computers, or are you bringing some in?
dmbaggett, I apologise that you have taken my message this way, and it's true I have been influenced by the all-too-common tone on this site; but I stand by my original comment that this is a line to spread FUD, like any company who tries to make out that their product is so different to the competition. You have unique features I'm sure, a unique take on email - don't rubbish your competition by spreading what is demonstrably not true for most email clients.
Using Chelsea as a reference point for London prices is akin to using Rolls Royce as a reference point for car prices. Yes, you have to pay more to show off if the BMW isn't upscale enough for you.

There's plenty of choice of central locations with good housing, transport, reputations and nightlife where £25k per annum gets you a very nice flat indeed.

Here's an interesting thought: maybe Obama's intentions are good but he's in a bubble of information and influences that corrupts his thoughts to overlook the the very concerns that alarm the crowd here at HN.

I'm of the naive opinion that he is not a sleeper muslim communist agent bent on destroying America; that he really wants to do the best he can for America.

He's not always right in his beliefs, but has been public about his intentions, e.g., continuing engagement in Afghanistan.

Anyone fleeing the police in a news-worthy chase is actively committing a number of fairly grave crimes. Usually excessive speeding (5mph over isn't grave, but 60mph over is), reckless driving, willful endangerment of others... you don't need "probable cause" when it's happening right there in front of you.
so 1500 GBP is about 2420 USD
1 bedroom in the good part of SF, USA cost about 2500/month.

Sure, there's no council tax and utilities are cheaper. Still, its pretty close.

I bet Paris ain't so far from that either, and let's not talk about NYC.

Basically, all of the large tech cities prices are "batshit insane".

The only hope I see, barred 1h30/2H by plane travel time, as the author suggests.. is remote work whenever possible.
You can then live 3-4h away from big cities (so you can still get together if needed), and prices are slashed by 10.
This is amazingly cool. I was excited about this from the first time Elliot mentioned it to me, and I'm thrilled to see how far you guys have come. Way to represent the Triangle!
Angry Birds was released in South Africa earlier this week. Almost 4 years later.
Some food for thought about who is organizing this rally: http://www.salon.com/2013/10/21/dont_ally_with_libertarians_...

It's a difficult topic, of course. Opponents of libertarians are quick to point out that the libertarian agenda leads into quite the dystopia. In particular, on the topic of surveillance, it seems fairly clear that at least the hardcore libertarians (in the direction of anarcho-capitalists and the like) are actually happy with surveillance - as long as it is done by private companies and not by the state.

Now these groups are co-opting or even running this campaign which is ostensibly against mass surveillance. That seems something right out of the libertarian propaganda playbook (for a recent collection of quotes out of this playbook, see here: https://www.nsfwcorp.com/dispatch/lying-to-liberals/).

On the other hand, protesting mass surveillance is still a worthy cause. I am not a USian myself, and I can't really tell where I would land on this issue (support stopwatching.us or not) if I were, but it's an important issue to think about.
It was outrageously easy to get credit, which let to the prices going up, and then the crash. Now the answer to the problem seems to be more of the same.

You think thieves stab people? Why would they do that?
This is really cool. I could see another application for it - Teachers delivering music lessons to students. As a drum teacher this would be a perfect platform for me to deliver my lessons, assuming you could support drum music (but there's probably a market for this among guitar tutors). I'm imagining a billing system where students pay to subscribe to my lessons and you guys take a slice of the pie.
I'm confused by this. This guy has publicly admitted, in detail, that he started a site specifically in order to facilitate copyright infringement. Regardless of his view of his own "intention", this is a violation. He's enabled piracy and has stated his specific intent to do so, and he is not a government agent.

What if someone started a club where drugs were sold and then publicly announced a year later that is why they started the club? Except it was supposed to be a citizen's sting operation? And he was trying to get a payout from the feds by providing information? Does he think that provides immunity? My guess is they'd nail him to the wall while laughing at him.

Hasn't this guy opened himself up to legal action, both governmental and private, by his statements? He has stated publicly that he enabled "illegal" activities IN ORDER TO MAKE A PROFIT.

What about Nuke Piracy's complicence through acquisition?

On another note, that is in no way an analysis or conversation starter, or even constructive: what a prick.
You over simplify too. Shooting someone in a war zone with confusion explosions and well, a war happening is a bit different to assassinating someone with a drone. Calculated and controlled targeted killing of an individual is nothing like the front lines in WW2. It is an awful lot closer to murder in my opinion. But human rights haven't been a strong suit in US policy, particularly when off US soil, for some time.

Edit: badly worded.
Is an aborted pursuit really going to have that much of an impact on the public's assessment of the viability of evading arrest by fleeing?

More importantly, is that cost not worth bearing if a policy of aborting pursuits in certain circumstances — where weather conditions are poor, the suspect is driving particularly recklessly, etc. — significantly reduces the number of innocent civilians killed or seriously injured in the course of police chases?
I'm working on http://algorithmic.ly -- algorithms as a service.

It's cool because I get to help startups who don't always have the resources to hire someone like me who specialized in implementing and scaling certain kinds of algorithmic features. These startups need help with everything from geospatial search up to anomaly detection and predictive analytics.

It's bootstrapped, so while I'd love it if it was a public offering, at this point it's still a hybrid consulting/data-services company. Eventually it will be a public platform, and I hope we can help a lot more people!

"if pi is normal it's likely that each appears infinitely often."

Not likely, _certain_. If there is a sequence S that appears a finite number of times, there is a N such that as never appears after digit N. That, in turn, means that, in the limit of L => infinity, the probability that S appears in the first L digits is zero.

Introducing Hacking to the Younger Generation
NYTimes: The Information-Gathering Paradox
Uhm, do you understand what "focused exclusively" and "no support for earlier" mean and how they differ from merely adding "Py 3 support" to a legacy product?

Any resources (time, attention, research, answering user questions, design simplicity, ...) that are expended in an effort to support pre-3.4 versions and users are resources that could be turned instead to the challenge of making the 3.4+ product even better.

With this approach, he could potentially, gradually, change the market's mindset from "mod_python is dead, use mod_wsgi" to "if you're still stuck with Py2, you'll have to use mod_wsgi, but if you are starting a new project, you should go with mod_python."
