>That's a really poor example that only applies because you chose to use the term "murder" rather than "killing." Killing is not wrong because it's killing, it's wrong for more subtle and practical reasons -- something that is easier to show if you don't go around wantonly calling killing 'murder.'

No... I chose to say murder because it is not generally agreed that killing is wrong, even today.

Most people think that killing in self-defense, for example, is permissible, and sometimes admirable thing (though again, there is much disagreement on exactly what self-defense is) Hell, a lot of people think that killing in pursuit of a sufficiently emotionally charged goal is okay, see collateral damage in wars of choice. Many people think that killing in defense of property is okay, and many people disagree with that first set. I could go on and on.

In the country where I live, most killings are auto crashes. Clearly, most people don't think that this is wrong, considering how loosely we regulate who can drive (compared to, say, who can carry a gun) Hell, I am about to go to work; getting there half an hour earlier (vs. what it would take on my dramatically less dangerous to other people bicycle) is apparently worth risking other people's lives to me. Now, I don't feel particularly okay about this, and I mitigate it somewhat by carrying more than the usual liability insurance, but I'm about to step into my car and drive.
I loved Perl 5. Now when Perl 6 is out, I'm a bit confused about versioning. As far as I understand, perl 6 files are of .pl6 extension. Why would that be different from regular .pl, giving that it's just a new version of a language? I mean, I have never seen things like .js5, .php6, etc. Next, is `use v6;` mandatory? Quite confusing. Am I allowed to do `use v2;`?
But a zoo isn't a natural environment anyway all the animals are in a fairly confined area it's not like they could run a kilometer away to escape.
On the short list of places where even those tired of hearing about Python migration problems have to admit the discussion is relevant, I have to imagine the Perl 5 to Perl 6 discussion qualifies.
The issue is far for being so white and black.

Not all the growth come from free markets. More efficient use of resources and the discovery of new technologies come from improving our knowledge. Sometimes this is done by business, sometimes no.

Also, there are economic theories (even mainstream economic theories) that express the view that some kind of redistribution is necessary for keeping the engines of growth working.

I think the analysis of the strategy's chances of winning is faulty. We can assume that the adversary chooses A and B such that P(A < B) = ½, since otherwise the optimal strategy is to always guess A < B or B > A depending on if P(A < B) > ½ or P(A < B) < ½.

Now, analyze the game using the standard approach of breaking it down into simple, non-overlapping cases:

R < A < B: lose
A < R < B: win
A < B < R: win

R < B < A: win
B < R < A: win
B < A < R: lose

Thus the probability of losing is

P(R < A < B) + P(B < A < R)
= P(R < A ∧ A < B) + P(B < A ∧ A < R)
= P(R < A)*P(A < B) + P(B < A)*P(A < R)
= P(R < A)/2 + P(A < R)/2
= 1/2

There is no paradox: no matter how you choose R, you have exactly a ½ chance of winning.
I've been wondering for a while, and since this thread seems to have attracted people who may have answers…

Can you (or anyone) provide any insight as to why ACL2 doesn't get mentioned much in discussions of formal methods? I'm interested in formal methods and ACL2 seems like a nice tool, but at least on HN all I usually see is Coq this and Coq that, with occasional mentions of TLA+ and Isabelle.
Did I say anything about keeping or even opening the packages? If the drone is using some sort of convnet or HOG to detect the landing pad, I can only imagine hilarity would ensue if its visual field were saturated with multiple copies of the target image, a sort of visual DDoS if you will...
You didn't look very hard: https://www.reddit.com/r/videos/comments/3k2bxt/yelp_salespe...
Maybe. It still wouldn't be foolproof - after all, Yelp Check-ins are powered by an API that trusts the coordinates it receives.

It might be possible to craft a request for that API. And even using a legitimate copy of the Yelp app to make requests, a jailbroken iPhone can change its coordinates to whatever you want. An Android doesn't even need that - just set it to developer mode and you're ready to fake check-ins all day.
If you want to use the energy stored in the rotation you'd need stiff tethers, not a slack line - more mass, shear forces acting on the tethers, can't be reeled in. Moving to a non-rotating part of the ship requires a hub and a way to move to the hub - that would either require a space-walk up-hill against the artificial gravity (yay, climbing about a quarter of a km in space with an eternal fall if you loose grip) or a tether that's massive enough to move through - but then we're talking a very massive space ship, not about a rocket stage as counterweight.

"Hustle" in LearnStorm is intended to reward productive persistence in learning how to tackle a new math skill. We don't go into the details of how we measure that because we want the kids to just do the challenge as they naturally would.
To be fair to the CBC, they were very critical of Harper from the start, even before the funding cuts.
Loss and grief are part of life. Your parents will die. Your grandparents as well. You either die young or live long enough to see some of your own generation die before you. If you are really "lucky", you see all of your friends die.

Death is a part of life. Everyone hopes that they outlive all their children, but even if you do not, tragedies during your life do not mean that your entire life was unhappy.
10-20 mins bike ride via bike share - I use Overcast to listen to podcasts at 2x+ speed, shorten silences, and voice boost. Since I'm biking, somehow the speed of bike matches really well.

On Caltrain, I tether my wi-fi. If you're on the fastest bullet, don't bother trying to get internet, it doesn't work. Otherwise, the moderately fast bullet or the regular trains will give you reasonable internet to answer email.

Oh, I also use VLC with a tv show or movie and watch at 1.25-2X speed so that I can watch a whole thing in a fairly short span of time. You'll realize it works pretty well.

Additionally, I swear by Pocket (which also reads articles to you), Voice Dream (which integrates with a bunch of other things and can read to you as well at a fairly fast clip). If I'm reading, I'll also use the Kindle app or potentially have my Kindle with me.

If I'm reading an online article, I've been trying to train myself with Spreed so that I'm reading faster.

I've seen others just play games on their mobile devices or use dating apps - both of which seem to magically make the commute disappear.
Listing features is a bad way to choose a language[1].

Program something in it, and if you get a good feeling, then probably a lot of other people will too, and the language will take off.

Larry Wall is a linguist, and I think that is probably what sets perl apart more than anything.

But yes, it happens to have the kitchen sink, too.

A Closer Look at the Bladecoder Adventure Engine
This reminds me of the C64 game Scalextric, which had an integrated level editor with blocks inspired by its real-life counterpart. There were turns covering different angles, which (at the time) made it very hard for me to create a custom level. :)

Paper author here. We did a follow up study and found that the mutation score is, in fact, correlated with the suite's ability to detect real faults, at least for the programs we studied. That paper is also on my website: "Are Mutants a Valid Substitute for Real Faults in Software Testing?"
I've also seen this first hand, except rather than a bad review, a bunch of 5 star reviews were made invisible. 3.5 stars on yelp vs 4.8 on google. From then on I've always used google ratings instead of yelp, which also has the benefit of being integrated well into the maps app.
Little Bites of Cocoa #136: XCPlayground Basics
I've used it before. Not for anything "production worthy", but the tool I built is seeing at least monthly use at my company, seems relatively stable (hasn't broken yet), and was way easier (for me at least) to write than the same app when I originally wrote it in Angular.

I had a bit of trouble convincing it to redraw when I though it should, and ended up throwing in way more m.redraw()'s than I probably should have, but it works, it's responsive, it's fast (if you couldn't tell that already from it's benchmarks), and it's fun (for me at least).

*Note: I haven't bothered looking into React yet, so I have no real comparison between the two. But Mithril suits my style of development, and that's good enough for me.

P.S. The templates look really nice in CoffeeScript too, for what it's worth.
GitHub's fork management is lacking, but as it is now, forks are a symbol of popularity, so authors have no incentive to prune them. Plus it would be like saying "you're not a real contributor" to fans (which, while probably true, is still rude and not worth being a jerk about).

A simple first step would be to hide forks publicly that don't have any commits since they were forked. But I think some people fork things because they think it's like adding them to their resume (I can't understand it) and they wouldn't be happy.

The entire concept of "forked from X" is broken.

I run the restaurants team at TripAdvisor and we're working to solve problems in finding the best place to eat. If you think you can do better, you may be right; come prove it!

Drop me a line, especially if you're excited to work on big piles of data, NLP, ML, a heap of phone stuff and crazy stuff like using word concreteness scores to analyze review value.

Please don't donate to the Mozilla Foundation or any other software foundation for that matter. Most of the time they are over politicized and the money is used to pay the salaries of open source politicians or to fund campaigns that they will put in their resume so that they can get a big execs job once they get tired of their open source stepping stone.

It is not about technology, as they say, it about "people". What you might not know is that the people they are mainly concerned about is themselves. It is very hard to corrupt, defraud, steal and cheat on a project that is just about technology. So they have to make it about something else, something that transcends technology so that they don't have to accountable by any metric.

All of this, am sure, may sound a bit harsh for people who are unaware of the inner workings of foundations behind their political, marketing façade. However, it should come to no surprise to anyone who has had any experience with the government in the real world. We would like to think that open source is above all of that corruption and in some ways it is, but I have to repeat my previous point that Foundations aren't about OS, they are about "people".

The corruption within Foundations is subtle, but it is present and I would like to argue that it is unavoidable. The reason being is that if tomorrow I get the job of chairman of the Mozilla Foundation, I will do my best to use the funds to promote campaigns that will look good on my resume to that I can use it as leverage when I apply for a big execs job at Intel. I wouldn't give less of a shit, if those campaigns are ineffectual, wasteful or over politicized.
You could always update Wikipedia using this article as a citation.
You know what I bet'd really pique their interest around reviving Persona? Not a donation, but start talking about it and evangelizing it, and get together with other interested devs to get them to do the same.

Mozilla's going to respond a lot better to widespread public developer interest than to a $100 donation.
My thoughts go that way too, but I expected some volumes to be more important than others. And because of it, I expected the article to measure a negative correlation. Hence my surprise.

But reading the paper, the study is about random samples of the complete test suite, and the results are far too weak to get any conclusion about it, finding negative correlations some times, and weak positive other times.

Anyway, they got a strong correlation, with good p-value (not very worthy on this context, but it's all we get) for your hypothesis about coverage volume. It's just my hypothesis about some code being more important than other that is inconclusive.
Computing the mutation score using a randomly selected subset of the mutants seems to work well, though it hasn't been studied a lot. One paper is "Reducing the cost of mutation testing: An empirical study" by Wong and Mathur.
This sounds similar to Bridgewater's culture of radical transparency. The first I had a debrief with my boss I cried all afternoon, but now it's growing on me a bit. Or I just have Stockholm syndrome.

I'm in Florida now but I did live in Atlanta for a few years and, if pushed, yo puedo hablar espanol suficiente para un conversacion simple. La problema es que no tengo oportunidad para bastante practica para fluente. So, I'm kind of in this half and half limbo where I can understand and speak enough Spanish but not enough that any native Spanish speaker would actually want to have a conversation with me. And for the other person who brought up the buying and selling to Spanish speakers aspect, the vast vast majority of Spanish speakers I've ever came in contact with speak a hell of a lot better English than I speak Spanish so that doesn't really make sense in practice either.

Multiple dispatch in a scripting language is enough to make me take a serious look at Perl.

Bug Bounty Ethics and the Ubering of Pentesting
What appeals to you about the new regex system? Is it a new syntax or an expanded feature set?
The extension is not mandatory. Usually people use .p6, but you can also use .pl . Notice that I've never seen .pl6.

'use v6;' is not mandatory either, but it allows your program to display an helpful error message if you try to run it with the perl 5 interpreter. Try "perl -e 'use v6;'", you should get:

Perl v6.0.0 required--this is only v5.20.2, stopped at -e line 1.
BEGIN failed--compilation aborted at -e line 1.

'use v2;' will not run with the Perl 6 interpreter, but 'use v5;' will work, as the Perl 6 interpreter is specced to be able to run Perl 5, albeit with certain limitations (no XS, for instance).

What is candor? Speaking one's mind? Revealing one's deepest thoughts? Mentioning things that you know some people won't want to hear?

When we think of candor we imagine a straight-talking cowboy type, or a brash New Yorker, or a direct and confident woman, etc. These images make us feel that if only we could tell it like it is all the BS would go away.

What candor really means is being unguarded. Think candid camera. We are candid when we make no pretense and avoid posturing, when we keep it real. This means we don't tailor our perspective and behavior to get a specific result or to seem impressive, we just do our own thing, like the victims of candid camera videos.

Real candor requires trust. Where organizations have major trust lapses is where candor seems the most lacking.

If a project is behind schedule, the organization should simply respond appropriately, which means either changing scope or changing the timeline. When there is finger pointing and pressure to lowball estimates, there is a trust breakdown from the outset.

If there is sufficient trust, there is no issue with candor because you just say what you want and everyone knows you are trying to make things better. When trust breaks down, your words might seem critical or like personal attacks.

So having radical candor is great, but it means having radical trust. It must be safe to be on either end of the candor event :) That includes cases when a team member is not able to perform or when a team member wants a promotion that he/she isn't quite ready for. It must be OK to be honest in either direction, which means the firm should respect it if the employee wishes to leave, and the employee should respect it if the firm isn't happy with performance and there doesn't appear to be a path to improvement.

All in all, having a systems mindset and a growth mindset goes a long way toward having a high trust culture. But startups are at a disadvantage from the start since everyone is expecting a massive growth trajectory and in many cases founders are quick to blame mistakes on specific individuals to explain a bad quarter. Having a culture of trust requires the team taking it on the chin and the board supporting and encouraging a systems approach.

So if your founder is the only one in board meetings, chances are that is because blame is being cast and deception is occurring on in both directions.
> Naive question time. Is Perl 6 something that non-Perl developers should be looking into?

As a non-Perl dev who has been looking into Perl 6 after encountering some posts and samples, I'd say it is, though unfortunately the kind of documentation that would make the most interesting bits easily approachable is still somewhat lacking.
I've no idea why you were downvoted. Python is indeed going through an almost identical transition, except that 3 does not fix as much as 6.
Your whole post is you pointing out that you are willfully ignorant. Congratulations.
I hope this does not fall on deafs ears but I am experiencing this EXACT thing with OVH(Canada's Mega Datacentre).

I have compared speeds directly to OVH's servers, and indirectly through a reverse proxy, and AT&T throttles direct connections to OVH. When I prompted OVH about it they confirmed to me that AT&T requested that they pay them for priority bandwidth and they refused (as is their right) and now my customers get throttled to 200 kb/s when accessing my servers on OVH.

PS. OVH has arguably the largest data center in North America so this means a lot of services are being affected by these ISP's.
"you are going to finish all the Earth resources and die before you even get to a tenth of that!"

Its fun to watch the debate about the "before" clause, as if the precise fraction or integer matters in the long run, when the real problem is nobody wants to face the reality of chopping off the entire "before" clause.

Once we stop economically extracting cheap oil energy, resulting in a roll back of the green revolution productivity gains, in a couple years at best its game over for about 95% of present humanity. Good thing the supply of cheap oil is infinite, right?
Wait, but the customers here are Hetzner's customers, right? How would they move to a different ISP?
What implications could this have for oil? Isn't oil bought and sold using US Dollars? I've always heard the World "Does Business" in US Dollars. Is this the beginning of the end for the Dollar as an international norm?

Fair enough, I admit that comment was not one of my finest and should have focused the argument on the substance of HTTP/2 itself instead of it's contributors.
Oh, no, I need the MOSFET anyway because of the load. I generally meant "I'll avoid unknown components/experiments with the BBB", thanks!
This bothers the hell out of me. I reflexively rate anything on any platform 4 stars if I like it, leaving one star as "room for improvement" if I can think of any one thing I wish they'd done differently.

But the modern convention is 5 stars as "good", and getting too many 4s is a failure.

What's wrong with, "As a listener, it's very distracting; moreso than you might think. You need to kick that habit to be an effective public speaker."? It's entirely possible to be candid without putting another person (your direct report, even!) down.
I remember the CBC under Martin and Chretien (both Liberals), it was far from fawning then. Right now the government is doing good things, it's good that they aren't always critical, then it would be a useless signal. And the CBC was pretty even balanced during the first 3 years of CPC leadership, it was only after the Scientist muzzling and the lack of media access / questions that the CBC starting upping the criticism.
Yelp will perish, because, unfortunately, the moral quality of the individuals isn't high and the founders/CEO seem to be blind to it.

As much as you need to be a very good business man to build a business that Yelp is, you need to surround yourself with good people, and recently, plenty of good people have left Yelp, and realistically, there aren't many out there.
Inequality and the City
A big deal has been made about this, however it was inevitable and the only logical thing to do. With the substantial Yen debasement, Japan's economy is now less than half the size of China's. That will fall to 1/4th in the next ten years. Even if China were to need to devalue their currency substantially over the coming years, as is being regularly argued now, that would pale in comparison to what Japan will do to its currency in the next decade or two in order to manage their debt disaster. There's no sound argument for keeping the Yuan out of that IMF basket. The next decade economically will be about the US and China, with Japan and Russia fading further into the background, and the Eurozone continuing to struggle with Europe showing zero net growth (the UK will be a bright spot in Europe thanks to not being part of the Euro (see: the depression it has put Finland in)).
How far along are you? If you're not far along enough to show, don't bring this up. Regardless of how open-minded hiring managers are, it will definitely unconsciously bias a decision. Don't make it a deciding factor.

Paper author here. As someone already mentioned, the suites were made by picking a random subset of the test cases written by the developers, not by using a suite generation tool.

Now, our method is arguably not 100% realistic either, because in practice different parts of the program will have different coverage. Some kind of weighted random sampling might make suites that are a bit closer to "real" suites. I've been thinking about looking into that. I think our suites are realistic enough to make the results worthwhile, though.
