I agree 100%. You can't just say "X% better" without defining the specifics of the environment in which you're operating. If they're claiming X% better in all environments, they're absolutely, 100% full of shit and they either need to stop outright lying, or do more work to validate their mistaken claims.

I'm not an ME or an expert in fluid mechanics, but I'm still curious.

I wonder how the efficiency of this compares to maximum power point tracking coupled with variable pitch turbines (minimizes airspeed required to start, but adapts both mechanical and electrical parameters in order to have peak power transfer at every windspeed)?

I wonder how the boundary layer introduced by the duct impacts efficiency. I understand there is a relationship between air velocity and efficiency, and I assume that it's easier to make high velocity systems more efficient, but in a ducted system such as this you're trading some of your total energy for a bigger pressure differential, and therefore speed. Is the amount of energy you're trading made up for by the gain in efficiency on the low-speed end of the curve? I imagine that on the high-speed (ambient wind, not flow over the turbine) end of the curve there's a drop in efficiency. It would be nice to see this quantified.

One of the acquisitions (SCHAFT, Inc.) is a competitor in the current DARPA Robotics Challenge, and out of all of the teams that have shown off progress videos, SCHAFT has shown the greatest level of competence in handling the tasks as they're going to be structured at the Trials in Homestead in a few weeks. Very similar to what they did with the top team from the last DARPA Grand Challenge (self-driving cars).

The irony is that the majority of the terrorist attacks on planes in recent memory have been stopped by vigilant passengers on the plane itself. Since 9/11, using the plane as the weapon is no longer an option. The passengers are going to fight back, without question, a la Flight 93. Additionally, reinforcing and locking the cockpit doors post 9/11 has put a stop to physical takeover of the aircraft, along with an expanded air marshal program. Bag through an x-ray and walk through a metal detector should be more than sufficient. At the airport in Jakarta, Indonesia, that is how it works.

Of course, the problem is that we now live in a fear driven society where the bad people are literally around every corner and each time we step onto an airplane we are taking our own life into our hands.

> because it has too small a user base

Maybe we should instead speak to potential user base.

For OSX, the potential userbase is always whoever has the money to buy extremely pricey Apple hardware, at least if you want to game on it, since getting a competent gpu almost always requires the rest of the components be really pricey.

For Linux, it is the sum total of all PCs out there with compatible hardware and firmware that can boot a Linux iso. Sure, you have to subtract the subset of the population that would never be able to install it - which is quite sizable - but you also have to consider they don't have to do it themselves, a tech shop or techie friend could.

> It sounds like a development nightmare.

When I develop for Linux, I use the Open Build System and throw my build script up on the AUR. If you are writing games you are using SDL, and if you aren't I personally use qt. Through that, I get FS access, services acccess, apis for almost everything, such that I don't even need to care about what audio backend you use, what your window manager is, what display server you use, etc.

Yes, there might be bugs, but unlike the Windows model, which is write for the buggy APIs because you can't do anything about it, on Linux you send the bugs to the upstream projects they originate from. Yeah, it is about 2 years until that bug fix sees mainstream adoption, but it beats using a buggy DX call for 15 years.
Happy to hear that, I will update the article with your comment,

Do you plug your in your iPhone without permission?

I've always thought that plugging in at random spots was theft, however small the scale, and applauded the coffee shop culture for offering WiFi and power as a cost of doing business, but without at least some form of permission, make no mistake, stealing power is no less theft than stealing cable, or gasoline, or whatever.

You need to seriously rethink that statement. How could a jury be expected reach a correct solution when exculpatory evidence was hidden from them?
lol yeah this is what gets me too. I'd be pretty damn surprised if a company i was applying to (so they will be conceivably paying my bills for a long time...) would give me $450 to sit next to one of their programmers and slow him down for a day.

maybe I wouldn't say anything too valuable unless it really seems like it will tip the scales but this is part of common sense and good judgment at any job -- if you publicly spill too many good ideas, others will repeat & steal credit. plenty of corporations will hire with a couple hours of interview but i don't really expect startups & small companies to work like this realistically. They probably need to be more careful with hiring. if you're obsessed with your "day rate" and think you can get people to keep paying it, then just keep freelancing...

the point of a job is to get a steady check every week in a more relaxed environment than freelancers typically face. if you want that opportunity, you have to prove yourself. the idea that they are trying to trick your fantastically brilliant mind into solving their problems sounds like a Ruby-ists fantasy or something, lol.

Just get real now and then, the author made fun of them for hiring [Hipster programming language] but he sounds just like [Hipster programmer]. If you walk into a place and you are not feelin the vibe then you are free to leave. Their request seems far from egregious though, I've done a pair interview before and it's strange but you're pretty much just shadowing someone and hangin out. They're not going to set up a dev environment for you and give you the keys to the codebase, come on.

I really like the idea of these multi-platform bridges.

The REPL lets you test any call sites immediately after you make a change. I do this all the time at work. Let's say I change a function that accesses the database, I can update the function then update the call sites and run them right there and then.

At least in Clojure, the REPL is integrated in the IDE. I can use the IDE to tell me where the call sites are what references the function, jump to definition, etc. Then I can send code from the editor directly to the REPL to test it out.

I use Intellij with the Cursive (http://cursiveclojure.com/) plugin, but you can do the same thing with Emacs and Eclipse.

My experience is that unit tests make sense in some scenarios, but not in every situation. On the other hand, high level integration tests act as a contract for your application. You should have these regardless of whether you're working with a dynamic or a static language.

5 Holiday Gifts Every Entrepreneur Can Afford To Give Their Team
For example, this comment would have made a lot more sense had it had a footnote reminding everyone that Sam is a partner at YC, and therefore does have reason to keep HN in mind as an audience when writing.

I had to figure that out from other comments, because my first reaction was, "Why is pg taking the time to tell some random blogger how to tailor their writing to this audience?"

(I'm a casual HN user, and don't keep up with YC, maybe the identity of the partners is more common knowledge in the larger population.)
May I take this opportunity to introduce you to a paper that me & my colleague from UCL have recently published.

Part II at http://arxiv.org/abs/1310.7935 - "The Unreasonable Fundamental Incertitudes Behind Bitcoin Mining"

We have tried to address the same issue of the excessive electricity bills associated with Bitcoin mining. What we have outlined in our paper are ways to optimise the underlying SHA256 hashing algorithm so as to mine Bitcoins faster & in a more efficient manner. We have managed to achieve a 38% improvement against traditional mining techniques.You can imagine the impact as it could now potentially allow miners to save millions on electricity bills.

Indeed, there are problems that cannot be solved in a parallel fashion. If you are stuck with such a problem you are screwed no matter what is your architecture.

A whole lot of real-life stuff is either parallel or does not need heavy computing. This is why people started building massively parallel computers well before the last 6 years[0].

GitHub’s 10,000 most Popular Java Projects – Here are The Top Libraries They Use
I started looking in 1993 when I was
a researcher in artificial intelligence
at IBM's Watson lab. Before that I'd
been an MBA prof; before that, in grad
school getting my MS and Ph.D.; before
that Director of Operations Research at
FedEx.

In 1993-4-5, sent 1000+ resume copies,
just simple, perfectly formatted, factually
written, perfect writing and spelling, heard
back only a very few times, got only a few
interviews and no offers. I did nothing, but
Nothing wrong. Nothing. I sent resumes to
tech headhunters -- nothing.

All I wanted was a job, just a job, only
a job. I would have swept floors. I just
wanted a job. Did I mention that all I
wanted was just a job? I didn't want to
be unemployed. I did want to be able to
pay for food, clothing, shelter, etc. I
didn't want to dig into my savings and
inheritance. I just, just, just wanted
a job. But, I was 100%, absolutely,
positively, totally, permanently unemployable
at anything above minimum wage. That
was 20 years ago. Now I am doing a startup.
I've been a serious burden to my brother's
family. All I wanted was a job. I could
never get one.

My conclusion: Even in a STEM field, a Ph.D.
is resume poison, worse than a felony
conviction. You are just not wanted. It's
as if you are hated.

Again, the problem was nothing about my
personality, etc. E.g., before my Ph.D.
in a two week period I sent a few resume
copies, went on 7 interviews, and got 5
offers. No problem. After my Ph.D.?
Stuck in academics or something very close
and otherwise hated.

I understand, but for devil's advocacy sake, that leads to other problems for the content reader, such as:

* Duplicates. Endless duplicates.

* Rejection of good content because the headline is bad.

* Essentially outsourcing this function to subreddit mods, who have only rejection at hand.

If someone mods a subreddit, and they see a submission that's perfect except the person misspelled "intimacy" in the title, they have two options only:

* Accept it as it is.

* Reject/delete it and get the user to submit again.

There's a bit of high overhead there, and less of a powerful experience for the reader. I think that matters less with Reddit's mostly 15-25 audience but is more important here.

The 10 Weirdest Programming Languages
> Are there any good indicators for laymen what likely punishments he would have been facing if he would have continued to trial and lost?

For federal crimes, sentencing is generally governed by the federal sentencing guidelines. [1] The application is conceptually simple -- there are guidelines for determining the offense level for each base crime, guidelines for grouping offenses (some of which just keep the most serious, some of which start with the most serious and increase based on other offenses), and guidelines for adjustments to the offense level for various factors such as actual harms inflicted, the defendants criminal history, the defendants acceptance of responsibility, and so forth, and finally guidelines to translate offense level into sentence. But the details are quite involved.

Perhaps the most important thing to note, in the federal guidelines, is that in most cases, where multiple convictions are handed down for offenses involve the same victim and the same act or transaction, or different acts or transaction as part of the same plan or scheme, the offense level is set by the single most serious count alone -- charging multiple counts of the same charge basically just increase the chance of getting a conviction.

For state offenses, sentencing is handled by state-specific rules.

Ah, that's a good idea. I'd negotiate it down to an hour or two, then when they pull me over to an iMac, I'd pull out my laptop instead and be like, "OK, let's do this! Where's the repo? Are you using Vagrant? Great, I already have it installed. What's the command to run the tests?"

If after the allotted time I still don't have a working dev environment, well, that job's not for me.
It's being done, actually. Company called Ogin (was FloDesign Wind Turbine) is developing a 100 kW shrouded wind turbine that is similar to that idea. But it only works on small machines, can you imagine a 100 meter rotor with a shroud around it?

On that note are there any changes or improvements on the horizon that would let you fast user switch between two or more booted and running operating systems. It'd be great in the future if you could allocate a small chunk of your RAM to keeping the background machine in a chunk of RSm so it switches faster than you can switch between users on the same OS. E.g. Of 16GB of RAM, 12GBis allocated to the foreground OS and 4GB to the background. Then when you switch you get a near instantaneous switch and the 8GB difference is allocated to the now current foreground system as necessary.
The original 9/11 attack showed how simple traditional weapons could be used to leverage using four whole airplanes as nontraditional weapons, three of them with devastating effect, all of them with lethal effect. I think Schneier's point is correct that spending the same amount of money on intelligence, investigations, and emergency response would keep us safer than screening what innocent passengers bring on to airplanes, but current procedures for airport security are still a reaction to 9/11 as it happened then. I look forward to the day when we dial back airport security procedures to the new reality of reinforced cockpit doors and passengers who will fight would-be hijackers to save their lives.

I'll agree with that and add to it as well -- there's also the perception that powering up a whole car is an expensive endeavor. I can easily imagine that the cop who saw the guy plugged in probably saw dollars trickling from the wall, where a cell phone plugged in wouldn't seem as expensive.

I feel like petty theft incidents like this for first-time offenders should be handled more delicately -- e.g., he can pay back the amount stolen, and perhaps a $50 court cost, but while I agree that jail seems excessive for the crime, there was indeed a crime committed, and perhaps illustrating to the officers that it was only 5 cents worth of crime would lessen the severity.

Why they can't foresee this instead making work for free? I mean, you get a technical team who can interview the possible guy, talking code, you can know what's the guys skill level, if you cannot see how good he is in interview without making him do puzzles, work for free, then your team's technical skill is really low.
I'm also a bit curious just how difficult it would be to take down a modern jetliner if you had the run of the back of the plane and whatever you could legally bring on board.
There used to be a different process called KSA (knowledge, skills and abilities) that was even worse (from what I hear). I think this application would approach hiring more progressively, but they still need to do things like create written evaluations of candidates explaining why they wanted to move forward (or reject) each candidate. A lot of laws were created to avoid any chance of discrimination (or unfair preference), which leads to a much longer and slower process.

This article might be of help, though I am not at all an expert in this area. http://www.fedsmith.com/2011/10/10/creating-federal-resume-p...
I guess I simply don't buy that any terrorist on board -- even if there were several of them and they were armed with box-cutters and the like -- could ever take the cockpit. The doors are locked, the pilots are sometimes armed; and mostly, the passengers would never let it happen.

Even in the most extreme scenarios imaginable, the passengers would have a 20-1 advantage, and would understand that the cost of failing to neutralize the threat would likely result in their personal demise (not to mention the greater threat of using the plane as a weapon).
