The thing that never ceased to amaze me is the collapse of WT7. I can't explain it.
It's amazing to me how many people use ssh and don't have an ssh config. It would be easier to maintain a .ssh folder in version control then to install this on each host and ssh until it learns.

Your auto provision of servers with chef or puppet should be adding them to you .ssh/config with a pointer to the ssh key and special requirements like tunnels through jump hosts/ bastion hosts.
My personal opinion is the fun I would get in solving a challenge rathen than winning a prize. However, you have a point there. At the same time, the sponsors are providing other prizes too. There are some participants who are still learning Go and attempting the challenge.
People often have trouble applying statistical methods correctly, and perhaps often can manipulate statistics to tell a given story. And indeed, P=0.03 on its own is meaningless without an understanding of how a study is set up and a plausible hypothesis.

But inferential statistics is grounded in sound theory, and used correctly and with appropriate assumptions is a powerful tool to reason about data. Without it, how are you supposed to reason about (for example) study results? Appeal to intuition?

It seems to me that significance tests are not all-powerful, or foolproof, but are still a very valuable tool.
The source code for tcc is terrible compared to 8cc. I don't find its code readable at all.

Fabrice Bellards brain is incredible at getting functionality in a small amounts of code, but the code is not great for teaching.
Some research shows that we live in an unusually non-violent time period.

"Violence has been in decline over long stretches of time", says Harvard professor Steven Pinker, "and we may be living in the most peaceful time in our species' existence"

There are a bunch of nice graphs showing this here:

It says specificially in the readme is only supports linux currently. Also, CC=clang works fine on ubuntu.

I have tested on both Ubuntu and arch linux.
Maybe I'm just obtuse, but this graph makes no sense to me: http://lmart999.github.io/assets/cluster_gis.png

What exactly do the colors mean? And what do those brackets at the top and at the side mean?
I agree there's a good opportunity for simpler phones that still get some of the benefits of smartphones rather than a 10 year old Nokia.

That said, I don't see much in the article to suggest this is what Mozilla is going after. Yes, some of the devices will be cheap, but there are plenty of cheap Android and Windows phones too.

Even if an OS did target just this market, the problem would still be a lack of apps. They might not be the kind of users who install 10 home screens full of apps, but many of them will be interested in a handful of apps in different categories, so the long-tail marketplace still matters. That's where there's an advantage to an Android phone customised for simple usage, but still with the ability for a user (or their tech-savvy friends/family) to install a wide range of apps if/when they want to.
Why wouldnt you wait more than 15 mins before judging the movie ? It's not like the first 15 mins were complete crap either :P

Yes, what a goofy bit of propaganda. Anyone with a shred of ethics asks something like, "What if this were a Chinese newspaper, from a guy who invaded the US and went around killing people for the horrible crime of defending their home?"

(And unlike Afghanistan, the US is the world's hyperviolent bully.)
Apple kept Flash off the iPhone, at a time when nearly all web video was in Flash, and when iPhone was the phone to have. There was much gnashing of teeth, but Jobs and Apple stood firm, and demanded the world come to them (which is their way, but in this case what they were doing was for good and not evil).

It definitely wasn't just Apple. Google and Mozilla certainly played a huge role, and I definitely consider them much better web citizens than Apple (Mozilla best of all, obviously), but a lot of sites switched to HTML5 video only because they wanted to be watchable on iOS devices.
It may have been rated 16+ at the time it came out, but it's really something that can be watched by younger kids nowadays.
General thumbs up for Fish!
I have no idea what the evidence really says on this topic, but I suspect the claim is more likely to hold true in the past era of huge conscripted armies, than in the modern error of small highly-trained armies (and small guerilla armies, which don't have large numbers of conscripts).
> "This movie has so many cliches in it," a boy said (...) My son told him, "This movie was made in 1986. It invented all the cliches."

The first boy was right. It felt full of cliches even then. I watched it in eighties as soon as it was distributed to my place and I all the time I had that feeling of "boring 'we're the marines' movie." And I still can't understand why would anybody consider Aliens an interesting movie. The first Alien is however something else. And I was always amazed to later watch "The Dark Star" made before the Alien and find it (among the other things) an Alien parody made before the Alien(!) It's really so thanks to Dan O Bannon. Now that's something. Aliens... not even worth mentioning.

Watch Alien, watch The Dark Star. Forget the boring Aliens.

Disclaimer: I'm old enough that I've watched the Star Wars in seventies in my movie theatre. And Mad Max. And and and.. Of course Aliens were already cliches and cliches.
You and Jeremy Bentham both.
No the idea is you set memory to write permission only, write out the jitted code, and switch the memory to execute, no write before you execute it. It simply means more calls to change memory protection, which is on page size granularity so may mean using a whole page for each jitted fragment.

What annoys me about a lot of time management advice is the same thing that annoys me about bucket lists. Acting as if the entire measure of the value of your life is how "efficiently" you spend every second.

I totally agree about having a "stop doing" list, because that shit can eat up your whole life on stuff that you didn't actually enjoy. But leaving space for coincidence and serendipity is important too.

And doing useless things sometimes, so that when you DO need more time, you have something left to give up that's not important to you. If you're already maxed out with valuable uses of your time, there's no room to add something else.

(crossover: decluttering and the "get rid of something before you add something")
Just today I released a small Go package which wraps JSONB in an API similar to `database/sql` for the purpose of rapidly prototyping apps.

Diminishing inputs, too.
Aliens is one of my most lived movies of all times. But if you plan on buying a copy of it, please, please make sure you are not buying the Director's Cut edition. The ones with 20 minutes added to it. Most of the additions are useless (or just plain bad) and spoil all the surprises the movie had in its first cut.

Many, many times I find that Director's Cut is just synonymous with "take the best cut and fill all the crap we did not think was worth it in the first place".
I live near SF. Where are these theaters?! Coming from Austin, and it's Alamo Drafthouses, I've been really disappointed with the talkers in films around here. Most movies that I've seen in the SF area have been filed with talkers.

> I feel like one thing they could do to promote Firefox OS would be to make it possible to run Firefox OS applications on Android; create an installer/app store that would allow you to install them as if they were native apps, but they would be using a shared runtime.

Good news! That already exists in Firefox for Android, it's called Firefox Marketplace, it works by packaging up the apps as apks, which means they can operate as native android apps with access to native device APIs.
It is true that ZFS or BTRFS are relevent even without RAID/redundancy. But that is not the point of the article.

It's about the redundancy / RAID features and their limitations.

Maybe I've should have written 'in this context not so interesting'.
-pedantic gives "warning: array initialized from parenthesized string constant" for that, so I'm guessing it's an unintended consequence of a nonstandard extension. Might be worth reporting since at the minimum the warning is wrong.

That's a rather negative way to look at his writing. Sure, he still has plenty of room for improvement in his writing, but it definitely doesn't qualify as a "cheap knock-off." Is there anything specific you can point to, or do you just not like the writing?
A possible measure of good is "does it harm people" but that ends up excluding everything, so add details like "does it harm people who are powerless to avoid that harm". You can decide right and wrong by yourself instead of just following the mob if you can work out some rules that aren't just a copy of current popular opinion. Popular opinion is actually a fairly poor go at it. It's mired in racism, patriotism, and similar tribal instincts which almost entirely encourage abuse of various classes of people.

Regarding capitalism, of course it needs controls, but on this subject, it's hard to see the harm in giving intelligent people opportunities that will benefit them. Sadly, popular opinion tells us that Indians deserve to be poor because they have the wrong parents (aka, citizens of a poor country).
I tried that, but having just one bag was much faster. And saved me the mental processing of what goes into what bag.
RAID5/6 is only as fast as the slowes disk regarding ZFS yes if you talk about random IOPS. BTRFS performance I haven't measured yet.

RAID5/6 random IOPS can be quite good or as you can expect if you use MDADM.

The best solution seems to be tons of RAM for caching and ZFS with SSD SLOG if you need reliable and fast sync writes. But with ZFS, performance comes second over reliability.
Thanks, I'm glad it changed your view of the game. My goal was to show this beautiful isomorphism between the two representations.
This is an awesome exercise in data visualization. It's most striking to see how crack use was essentially flat until 2008, and then it started a steady decline. Looking at the charts, I would venture to interpret that the wave of gentrification following the market crash had the effect of disproportionately displacing crack users.

I wonder what this same study would look like across the bay, in Oakland.
Yeah I've read big names switching to RED (that's what made their business thrive). I was also referring to the disk space. A single person can assemble a 100TB setup. That was Pixar territory not long ago.

There was a BBC doc about Sandhurst a few years ago where they showed how they train recruits to kill people.

Basically it involves the delightfully low-tech method of having recruits charge towards a bag of grass cuttings and stabbing it in the gut with their bayonet while chanting "KILL!"

One of the recruits was so freaked out by the whole thing that he quit soon afterwards.

* deploying apps is super easy - either host them on a web server or push them from firefox's webIDE, and remote debugging using the firefox devtools just works.

* hacking core apps is totally doable. You need a rooted device to update them though. Currently the best ones would be nexus 5 or sony z3(c).

* everything that is displayed is html/js/css. What you call "framework" here is part of the system app (https://github.com/mozilla-b2g/gaia/tree/master/apps/system). It's a fairly large app, but it's where a lot of the fun stuff is!
Meth is quite possibly the most dangerous drug in existence. It's cheap. It's almost as addictive as heroin. It makes people aggressive, impulsive, and even violent for hours.

Now, don't go trying to convert meth-heads to doing crack. They're both very harmful.
My daughter was almost scarred for life by it. I think she was about 8 and she had a friend living in our building who was 4 years older. The older girl was into scary movies and I mentioned how Alien, the first movie, was one of the scariest I had seen. I explained the whole plot to them and then showed them the movie and they said it wasn't that scary at all. Long story short, I then showed them Aliens. Unfortunately I'd only seen it once and didn't have a strong memory of the plot, in particular I had completely forgotten about Newt. She ended up a number of phobias for the next year or so that she completely blames on me.

Type punning by pointer is explicitly UB per the standard.

Type punning by union is implementation defined behavior. Everyone fortunately defines it to Do The Right Thing (TM).

The truly standard supported way to type pun is by memcpy

float f = ...;
int x;
memcpy(&x, &f, sizeof x);
Yes, it combines that with the color hue equivalent: http://img.washingtonpost.com/blogs/wonkblog/files/2015/02/y...

On another note, I'm wondering if people did comparisons on whether the size at which you viewed the robe had any effect on people's choice. Personally I can't see it as white because there are enough cues in the background that indicate that there isn't a strong blue light lighting the dress from the front. On the other hand if I shrink the image and squint, I can imagine it being a sort of backlit photo where the blue tint would just be a result of outdoor atmospheric diffusion and the contrast with yellow sunlight.
You don't fall into the false dichotomy of even entering into playing that game. Your question presents a false dichotomy that (dangerously) is pushing things into trying to institutionalise a justification of killing a fellow human being. Worst, is trying to do that a priori. Is exactly what dictatorships, genocides and Eugenicists would use.
In Nature, and even in urban life, the chances of experiencing the Trolley problem are close to nil.
Many of the examples in this post are great examples of 'Modernist Art' and are decidedly not postmodern. This is roughly the equivalent of writing a post on "Functional programming is Anti-Mind" and then demonstrating that with examples from the Gang of Four Design Patterns book.

The real issue with this is that most postmodern art is incredibly accessible. You don't need an art degree to think that Roy Lichtenstein's paintings "look cool", or that Campbell's Soup cans are "neat". One of the quintessential, textbook postmodern film directors is Quentin Tarantino; there are few directors more adored by the general public. Postmodernism is a descriptive term for artists who mostly reject the Western tradition of 'High Art'. Almost all the difficulty and "unintelligibility" lies in postmodern theory, but not in the art theorists consider postmodern. And I would argue that this is because theorists themselves are artifacts of Western high culture and are therefore unable to articulate a response to something that is outside this framework.

Almost all examples of "unintelligible" art fall into some subcategory of High Modernism. High Modernist schools of thought are almost always exploring questions within the context of Western high culture(ie the "What is art?" questions), and for many of these works you need to have a background in the art in question to really engage with and understand the piece.

If you want to critique postmodernism a good place to start is Fredric Jameson's "Postmodernism or, The Cultural Logic of Late Capitalism".
Boston, MA | Android Developer | Fulltime

CoachUp connects coaches and athletes for 1-on-1 private lessons. (Think airbnb for private sports coaching.) We're a venture-backed startup that's been around for about 3 years now. We went through TechStars and MassChallenge. You'll probably find your typical startup culture and whatnot here, but I guess one differentiating perk is you get to meet professional athletes from time to time. Julian Edelman of the Patriots came by one day, as did Nerlens Noel of the Philadelphia 76ers, and others are upcoming.

We're looking for a full time Android dev to take over our Android app. Our backend is Ruby on Rails, and depending on comfort and desire you could work on the API side of things, too.

So the popular hypothesis is that the dress is black and blue.

I have now seen so many different sites and authors try to explain the phenomenon, all based on the "proof" that some random woman named Caitlin McNeil who first offered the disputed picture originally claiming she saw it as white and gold in the picture, saw it some days later in person, said it was definitely black and blue and offered a picture of an indisputably black and blue dress that appeared to be identical or at least too similar to be able to tell a difference definitely.

The issue to me is that I'm seeing sites like Wired and I fking love science explain how the dispute is possible based on optical illusions and ultimately say that the dress is black and blue because of the other image and the claims of a dress manufacturer with no credence to possibility that the dress in one picture may be different than the dress in the others and that dressgate might just be an elaborate hoax.

The thing is, you can just as easily explain why the dress is white and gold and appears blue and black to some people given the intense back lighting in the disputed image implying sunlight in the background and the effects of reflected UV light can play on shaded white objects (think black uv lights) or effects like solarization that can happen in digital imagery.

The thing is, I'm sick of hearing the dress is blue and black because "science", when science hasn't been involved in anyone's "proof" of the effect. What you have is a hypothesis. Want to make it a viable theory? Take the black and blue dress or one of the identical ones from the designer claiming that's their black and blue dress and recreate an identical image that appears white and gold with the same tonal qualities and environmental lighting. Until someone does that, I don't think there's any reason to continue "proving" why the dispute exists with non-science or arguing about this nonsensical bullshieza as it has become a gargantuan distraction from reality whether or not it was originally meant to be.

The colors are to normalize the different districts. The darkest color is always the most prevalent drug in that precinct, and the other colors in that column are relative to that drug.

The brackets are presumably an explanation of how the "clustering" was done, though with such a small data set it could have been done manually.
It was really the other way around. NetApp had Sun in court over ZFS infringing on WAFL patents[1] well before the buyout.

I certainly don't know all the ways people use their Macs, but it seems like ZFS would not get a lot of use in OS X unless it was the only option:

- It doesn't offer a whole lot over traditional filesystems in a single-device context; since Apple has basically abandoned server/enterprise, I would wager the vast majority of new OS X systems are single-drive.

- At the time Apple was supposedly making a decision about this, I am not sure if ZFS handled 4k alignment (ashift); this is very important now that a lot of new Macs are shipping with SSDs.

- You're still, even w/ 10.10, discouraged from using case-sensitive HFS+; at least one application[2] won't work on a case-sensitive filesystem on OS X.

The above reasons probably apply to Windows as well. Also, in general, it seems like both vendors want to be the sole source for all of their core features.

> This sort of behavior is not acceptable for a human being, heck its not acceptable for an animal being or a plant.

Animals are ruthless killers. Cats kill for fun. Plants aren't much better. In India, a captive elephant is allowed to kill two of its handlers before they will put it down. They suspect the elephants know this and pick their targets carefully. Only man has the ability to be moral, to decide whether the killing they do is legitimate or not. Doesn't stop us from killing, but at least we can feel bad about it.
