I eventually won and went on to score 32420, eventually losing after getting a second 1024 on the board. I'm fairly certain a 4096 is achievable.

The cardinal rule, as many have said, is to keep one side filled, in descending order, with your largest piece in one corner. Once you have that side filled, you have to make sure that any time you have a duplicate on that row that you:

(1) only ever shift toward your largest number

(2) ideally have a parallel row that will not shift before you do (1)

Until you can refill your last row, circumstances may lead you to have to move in the forbidden direction, which could wreck the whole game. Point (2) ensures that you can fill your back row with another piece immediately, restoring 3 directions of moves as quickly as possible.

If you end up with any 2's on your back row, you must build them up to higher numbers ASAP. Last thing you want is buried 2's.

Once your numbers start getting high, I think it makes sense to use the front two rows exclusively for 2's, 4's, and the occasional 8, but to shift 8's to the third row as soon as possible.

I've found that to actually finish once you have all the pieces you need, it may make sense to break script, but if you want to go on to try to make 4096, you may want to carefully stay on script.

I've found that in tricky situations when I want to combine large value pieces that are just not in alignment, it makes sense to try to slide lower value pieces under one to "boost" one of the others into alignment. The ability to do this makes it valuable to keep your combining pieces in the middle of the board.

Lastly, when you have multiple possible moves, make the move that takes most advantage of the piece that's about to appear, either because you can quickly combine the new piece or because it can "boost" another piece into alignment.

Follow this advice, and you will be a star!
Well, it's not like they can have a sandbox for any arbitrary language, right? Doesn't it have to correspond to some ABI?
the NMC network has some serious hashing power, look it up
People love to go on and on about the power of macros, but for me, what separates Lisp from the crowd is that it's a compiled language with a REPL.

Are they any other usable compiled languages with a REPL?

Secure Boot systems verify your OS against a key stored on your hardware.
I believe JAH's story. I hope she gets another great job and puts this behind her.

On a related issue, github plays a central role in the software development world, and possible signs of internal problems is troubling. It would be a good idea for the github management to properly address this story.
What do malls offer that regular shops do not (besides lots of stores being located closely together, but thanks to Yelp and local transportation, that doesn't seem like too big of a benefit).

UPDATE:

So I am from NYC, and I have lived in urban areas my entire life. Finding the right stores so that I could make immediate purchases has never been an issue for me, but based on early comments, I clearly have a myopic view.

I can see how a mall could potentially offer an "urban" experience (meaning that food, stores, people are all conveniently located in a nearby area) in a non-urban area.

Judging by your comment history, you do appear to have internalized your ideology very thoroughly.

But, no. First of all, your example is biased towards Western society. Expressing white pride in an Eastern Asian society would be absolutely fine, according to your logic.

Here's the issue, however. Even though black people have been historically marginalized in the USA (as I'm implicitly assuming this is US-centric) and still face disadvantages, despite being largely equal in most facets, this does not make their racial pride any less "asshole"-ish.

Pride is reserved for things once has accomplished, not ones that you're inherently born with. Just by that alone, racial pride is frivolous.

Even further, by setting up this double standard, you are actually contributing to the extension of racism. Why? You're giving people carte blanche to keep focusing more and more on racial characteristics as being essential to them as people.

"It's bad to be racist, but we still must be preoccupied with race and being inoffensive at all costs."

That is only slowing progress down. You go from a society that is maddeningly obsessed with race as a way to persecute people they don't understand to a society that is maddeningly obsessed with a race as a way to kiss ass, idolize and never question those majestic black people who can clearly do no wrong and deserve to have double standards because they have suffered injustices throughout their history.

Yet so have all races and cultures, honestly. Black people do not hold a monopoly on persecution.
You couldn't be more wrong. If you don't know any women who treat their spouses as other people, who have ups and downs, women who can't take "for richer or for poorer" seriously, then you're in the wrong social circles.

Hell, my wife has offered to let me quit my job, where I make nearly twice as much as her (her electrical engineering salary would be enough to get us by), just so I can work on art full time, because she knows it will make me happier. I haven't, yet, because I also want her to be happy and I'm not so unhappy with my work yet that I can't earn us some more savings and hopefully make an exit for both of us.
I think he was referencing secure boot checking the keys as being the main problem/cause of all the issues.
The article claims: "One reason all PC's that come preinstalled with a Microsoft operating system is cheaper than regular laptop is that Microsoft subsidizes the cost of the hardware."

I had always thought that PC makers paid Microsoft for Windows. The article claims that, instead, Microsoft pays the PC makers to install Windows. I don't see how this could possibly be true if most copies of Windows are sold pre-installed on PCs.
Facebook does of course have unexpected consequences on those priorities though:

> because white people have crafted a society to let them have more advantage.

Thinking of 'white' as a single group of people who are always middle class is a fantastically ignorant thing to do.

Does the white kid whose parents are Ukrainian janitors deserves a leg up less than the black kid whose parents are an English professor and a photographer?
I guess the point I was trying to make was lost on you somehow.

I wasn't trying to say this is the exact same thing and that racism is something you'd hear about as frequently as sexism these days ! I was trying to make the parallel that just a few decades ago it would've been a perfectly acceptable thing to play it safe and say ".. than that's who we're hirig." based purely on this kind of skewed reasoning about races.

The reason you hear more about women bringing up these issues is because more women are bringing up these issues, which until recently were either non-existent (because there weren't as many women in tech), or were ignored/hushed or 'dealt with quietly' -- much like race issues ...or for that matter general quality issues between the sexes. The reason you "...personally see and experience one and not the other." is precisely because the other (ie: racism) was brought up ...repeatedly ...dirt was kicked up ...fingers pointed ...positions defended ...often under the guise of 'ah well, this issue isn't about being racists as much as it is about the individuals'. In the end though, most people 'got it'. Hopefully you now see the parallel I was trying to make.

About your statement " That you'd even bring up the comparison makes me think you're not taking this seriously, as a reality to deal with and not an internet crusade." ..well, I personally feel this is a very serious matter and if you got any other impression from what I said, it possibly is due to my inability to get the point across.

About your statement "Read the statement again. I'm not laying blame on any party. I am only taking the position that whatever the cause is, I don't know any better than anyone else how to avoid it." ...I'm sorry, I really don't see how the 'I don't know any better than anyone else how to avoid it.' bit is supposed to be implied by " then that's who we're hiring." bit ...maybe my comprehension skills are lacking although I suspect they aren't and you're just trying to somehow deflect your earlier statement by misdirection.
I learned my lesson long ago. Linux is for VMs. I run vanilla Windows as my boot OS and then use Linux from within a VM, thus getting the benefits of Windows hardware compatibility where I need it. This lets me do things like run nine monitors when my laptop is docked by chaining DisplayLink adapters. Note that Windows with DisplayLink will only support eight monitors so for the ninth I bind the DisplayLink adapter to the VM for dual monitors with my Linux VM. Going above more than two monitors with a Linux host OS is akin to beating one's head into a wall, especially if you move between monitor configurations often, but just works in Windows.

Thus far, with the ability for the VM to bind specific hardware directly and not shared via the host OS I get all the benefits of a Linux host OS without the hassle of broken driver implementations taking me down for long stretches at a time. As an example, I can bind my ALFA WiFi adapter directly to the Linux VM and run aircrack-ng all day long.

Yes, there are drawbacks. You will need a bigger hard-drive (best if you can fit two in your laptop) and more memory, but those are cheap these days. The benefits, however are massive. I keep multiple VM versions and can instantly recover from anything stupid that I might do in the Linux kernel without impacting my ability to actually get my work done.
Yep. 100% right. I like your generalisation of the original statement in that the gray zone is defined by obvious mutual romantic incompatibility. For example, a heterosexual man also can help a heterosexual woman in a total professional non-romantic way if he doesn't find her attractive.
As I understand it, that's very outdated information. These designs have been passively safe as of twenty years ago when they were pioneered by the integral fast reactor. The plant can lose all power and will not ever melt down; liquid metal reactors just don't work that way.

One of the key advantages that recommends fourth generation nuclear reactor technology is that the design eliminates much of the existing "waste" (it's really just ~$50T worth of unspent fuel we have laying around that could power the entire world for ~1000 years) that's been produced by past and current light water reactors. A better estimate would be in the 200 to 400 year range now. That's right; we're actually capable of getting rid of nuclear waste with nuclear reactors.

Yes that's still a good number of years, but estimates for global deaths per year caused just by particulate pollution from coal power plants range from a conservative 100,000 up to 3,000,000. How many people per year is nuclear currently killing? I was pretty incredulous to find this out, but the answer is zero. And given that they produce negligible CO2 as compared with fossil fuels, they are recommended by the climatologist who is largely responsible for drawing attention to climate change since the 1980s, James Hansen. The conclusion (begins on page 116 of this .rtf file) in his 2009 book is worth reading:

http://ge.tt/5GTotjQ1/v/0

Ironically, traditional environmentalist movements that indiscriminately protested and continue to protest against any nuclear power technologies have effectively greenwashed the "clean coal" (wtf) mantra into existence because fossil fuel plants are the only other alternative for baseload. To me, this seems eerily similar to the protestation of tobacco companies that their products were causing cancer. We're still building coal power plants, but the CO2 sequestration they're currently talking about would require burning ~25% more coal to power the process, making it so uneconomical that it won't ever happen.

And since sodium-cooled fast reactors can also run on decommissioned nuclear weapons, decreasing the risk of nuclear proliferation, we have every reason to be using these technologies for baseload power and zero reasons not to. Given the choice, I'd rather live near a nuclear power plant than any other type. Perhaps I'd finally be able to get an electric car that would then be functionally carbon neutral, though maybe not avoiding the ecological damage externalized in the building such massive batteries. (That's something I still need to look into for myself. Anyone have any academic sources other than the Union of Concerned Scientists/Lobbyists?)
I hope it's okay if I go a little off-topic to talk about the design of this site...

Does anyone else have an issue with gray fonts and low font-weights? Gray text has been popular for a long time (HN has a heavy dose of it, for example), but the lightweight fonts seem to be a new trend. The contrast between text and background is just getting worse and worse, to the point that I need to have stylish installed just to make some sites readable. I feel like designers are designing for ideal setups like their own, and they're forgetting about people like me.
It makes all the sense when you consider the possibility that she might be a person that specifically collects even the smallest pieces of evidence to support her theories of sexism and bigotry in the workplace.
What does it mean to say that it lasts longer than wood framing? There are wood framed houses that are well over a century old, right? So is this being measured in centuries, or am I missing something important?
The Bretton Woods system
Hello everybody :)
Does anyone know exactly why the Bretton Woods system collapsed, and/or does anyone know any literature that contains an analysis of the collapse of the Bretton Woods system?

Thanks
glad to see the first electric supercar. but with a weight of 1950kg (4300 pounds) it's hardly going to feel like one.
Just download one of those Win7 activation-removed torrents. They just work, and loads better than the Win8 cesspool.
Looking through the materials for the interview you can see that they focus on two different positions which looked a bit odd to me but i split those two into SRE and SWE looking at each of the requirements.
Thanks for the link btw.
Technically, it is not "US", it is "private companies" (media).

Just like with censorship. Plausible deniability, but getting their way anyway.
Let's go ahead and assume GitHub is a meritocracy.

If you "succeed" and do "well" on GitHub (what metric can we use? Lots of a stars? Getting your name out there?), what does that actually prove?

If GitHub is a meritocracy, what have the "winners" done to set them apart from the rest, and how does that translate into the professional world?
Batman Intro to Python
Amusing Hacker News cognitive dissonance:

- "AirBNB is great! Will revolutionize the world! Stupid hotels just take your money for no reason! Regulations are only there because governments hate you and want to oppress you! By next week, 7 billion people will be using AirBNB to rent their homes to each other! And it's totally safe, because AirBNB stands behind each and every transaction!"

-- "Stupid poster, she should know that AirBNB is absolutely unsafe. She bore 100% of the risk and of course she should never have used this service. She was violating her lease and deserves everything that happened to her. Shooting is too good for her; hanging is too good for her. None of this is AirBNB's fault; they had literally nothing to do with the transaction and it's impossible to understand why the poster would ever have thought they did."
Apple makes both the OS and the UEFI implementation for their hardware. If the UEFI implementation caused any trouble for OS X, they could fix it before shipping the hardware. They also use a non-standard EFI implementation (IIRC the EFI partitions are HFS+ rather than FAT; whoever thought it was a good idea for EFI to read the partition table whatsoever should be fired).

The issue with PC hardware is, as it ever was, hardware vendors not following the standard. Much like Apple and OS X, they build some implementation and only fix bugs if they break Windows. So if you want to build a Linux implementation, you have to implement workarounds for all the quirks in different vendors' EFI implementations, and in the meantime you can't install on their hardware.
There's a way to make your point without saying things like "all of you".
A mall is a gathering place for many people of various age types. One does not simply go to the mall to shop. Sometimes it is to socialize.
Tragedy of the commons. A poorly designed scheme that may be at its breaking point. I do expect that as a country we will recognize the value of education (at least to the economy, if nothing else), and will find a way to educate young people. It may not always look like the current system, and IMO that's a good thing.

>Congratulations on a perfectly self-centered Millennial decision

Congratulations on your job! (and lack of empathy) Send yourself a nice greeting card "Congratulations kator, on your wise choice of [birthplace/parents/nationality/etc]." There are so many people who fail to realize the degree to which their personal success is dependent upon circumstances over which they had no control.

>I guess I'm old fashioned, I've never signed something I've not read and I always honor my commitments to the best of my ability and with honor and respect for everyone involved.

Is that because you're such a great guy, or because you've never experienced significant adversity?
I can't even remember the last time I set foot in a mall. I think it was to try on a suit, but even trying on clothes will be virtualized with augmented reality. Other than being a destination place to hang out, I don't see much utility in malls.
What you say is true, but I don't believe a contract of employment entitles any company to tell someone who they can or cannot date.

If, for the reasons you describe, they wish to maintain a public position of "we not encourage dating coworkers" that's one thing, so long as they don't actually think they have any say in this matter.
What is wrong with this culture of suppressing even the most basic sexual ideas to the point of closing eyes when a female starts to hola hoop. This is crazy!
The Radical Power of Classic Comedies
Most of its abilities is probably due to being made of carbon fibre.

The electric motor can only be so big and more batteries just adds weight so a lighter body is the only option.

It would like a V8 gas vehicle in which the engine or gas tank couldn't be changed leaving the only option to make a lighter body.
I think you're likely speaking from different societal/legal models of employment. Here in the states, when you're ready to fire someone, you fire them. Unless you're dealing with a union. Then there are 10 additional steps.
I realize that it works fine on Safari - you just need to turn on WebGL.
We haven't noticed any difference in results between batches. The only difference we've seen is that summer batches get more applicants, presumably because graduations mean more people are free to do something new June 1 than January 1.
Why did the developers 'revolt'? People shouldn't date at the workplace but it seems like there's something missing here.
It's true that most people leave the defaults. However, there may an easy solution for a subset of cases.

Do the browser defaults in any country include multiple language settings? It seems likely that in most countries, the default would be only one language. And if this is the case, then if multiple alternatives are present in the request headers, it's very likely the user or computer admin has deliberately changed it, and that in turn would mean that sites should respect the choices.

This might still be wrong in when the settings were made by someone other than the current user, or there are multiple languages default-configured, but it might be a step in the right direction.
Nice. So how can we recreate the gathering place in an era where the mall as a shopping center is no longer necessary or successful?
You can get cute about it:

http://code.activestate.com/recipes/384122-infix-operators/

The code there overrides | to construct arbitrary operators that are used by wrapping an object in |, like:

a |x| b

where x defines the custom behavior.
This is the core problem, though: it's difficult (impossible?) for someone to be professional when everyone around them is so unprofessional. Worse still when none of their claims are fully addressed by management.

There was no resolution here. I don't blame her for taking these steps to out Github.
Aside from the facts that not all malls are dying and that there are still new malls being built, they offer exactly the benefit you stated: "lots of stores being located closely together."

I don't believe the existence of services like Yelp offsets this much if at all. People who don't mind spending the extra time to use it and then to travel around to the places they find (or even wait for shipment) are not necessarily the shoppers a mall caters to, as they're obviously not so concerned with getting what they need quickly with minimal travel.

There's also the social and entertainment aspect to consider. Many malls have food courts and restaurants and/or include movie theaters (or even theme parks, which I find hilarious, but it's there).

Malls do often exist for and serves purposes other than just providing goods in a centralized location... but that purpose itself hasn't lost its utility.
I do the same thing, it works well. Do you use Windows 7 or 8 as your parent OS?

I use VirtualBox and have found it reliable for years.

The Windows host OS can then be kept very clean and it remains fast and relatively secure.

Then in those rare instances when you need to download something insecure or that you don't want cluttering your Windows install you can put it in a virtual machine that acts as a sandbox.

If you organize your files right you can even wipe your windows partition and reinstall with very little downtime and setup (other than the several gigs of updates that will be needed during the first few boots).
I installed Debian 7.4 on a Dell XPS 13 using a live hybrid ISO (`debian-live-7.4-amd64-standard+nonfree.iso`) two days ago. After enabling UEFI and adding the USB stick as a boot device, I had to do nothing out of the normal to get it to work. It was incredibly painless.
I was going to say something snarky about the 80s being the last time people did that, but there are occasional times I've had to go to a mall in the past few years, and I notice teenagers hanging out (usually in the summer).
We all know people we wouldn't want to fund, but there is not currently any software for it.
I looked it up later to see how correct my memory was and the thing I didn't recall was that it was a massive failure.
I sure hope not. Some of my fondest memories when I was growing up in the States was visiting stores like JC Penny, the random Electronics store or Jack's Joke Shop with my parents, then swinging by the food court and eating some Sbarros pizza.

When I come back home, I would like to take my son to the mall as well and spend the morning just browsing around and buying trinkets. It's fun!

Amazon may be cheaper but come on, going to the mall is not all about shopping, it's about the experience!
I am rather confused, who is buying Dogecoin to actually make this happen?
