Create interesting CS problems at HackerRank?
HackerRank is a growing community of hackers in different domains of CS. Hackers come to hone their skills, for fun or to connect with companies.

We have 4096 challenges as of now across all the domains and our MAU of hackers is growing at 30% m-o-m; We've a very similar momentum on signing up companies as well (fb, amazon, square, yelp, linkedin, etc.) are all our customers who use the platform to streamline their recruiting process. We're past a multi-million dollar recurring revenue run-rate and expanding rapidly.

We're a team of 80 people evenly split across Palo Alto & Bangalore and looking to hire a challenge curator.

Your role will involve coming up with new challenge ideas, working with companies on creating real-world problems, verifying the sanctity of challenges that our users already contribute to us, etc. - a role to manage the content (challenges) that go live on the site.

Our mission is to make the world flat - the only thing that should matter is your skill.

If you're interested in the role & believe you can help us accomplish the mission, write to me: vivek [at] hackerrank; we're just getting started..

Show HN: Founder Weekly – Must Reads for Entrepreneurs
Such bad advice given the inquiry. Obviously. Lot of OP's customers are going to want the "best" certs (whatever that means). Or they're going to want "they're name in green".

It's important to answer in the context of the question.
No argument from me on any of that, totally makes sense. And thanks for the correction of 70,000 m^3 -> 70,000 * 1000 m^3 for Crystal Spring Reservoir.

The most interesting book I've been able to find about this topic is "Superintelligence: Paths, Dangers, Strategies" by Nick Bostrom. At the moment its a #1 Bestseller in AI.

I think you are grossly underplaying the consequences of that plea deal. Six months (or less) in federal prison would still have him labeled as a "convict" and he would have lost numerous civil rights (voting being one) as a result. Needless to say, he would have to carry that label for the rest of his days as a US citizen. From what I understand, Aaron did not want to carry that cross, more so since he considered himself innocent. Hence, in protest, he took his own life. I am neither condoning nor criticizing his action and his final decision, as I am in no position to do that. However, I strongly doubt it was as simple or straightforward as you'd like it to appear. If you are a friend of Aaron's and you have come out publicly (on HN) as one, perhaps you could explain the reasoning and motivations better than most of us. Why not do that, instead of oversimplifying the whole situation?
I used Ansible and got up and running in 2 days. But for whatever reason, I decided bash was better because it was more portable, had fewer dependencies and frankly, how hard could it be to write bash routines to download files, unpack them, install packages, etc. Besides, bash skills are more transferrable.

After 3 weeks or labouring and using FSS with a fully working system, I dropped it all and went back to Ansible. I don't regret the time spent because I picked up a lot of transferrable skills from command line utilities and bash.

There are simple things like downloading a file which BashBooster gets wrong. If the file already exists, it should not abort, it should resume download or compare file sizes to ensure that the previous download didn't terminate abruptly. Basically, this and other idempotency issues need to be dealt with very carefully. Even simple things like "mkdir -p foo" instead of just "mkdir foo".

Once you get past idempotency you will most likely run into performance issues and then into project velocity.

If you really must use Bash Scripts, I would suggest using them via Ansible's Shell + Command modules. This will allow you to lean on Ansible until your Bash scripts can catch up. It will also give you Ansible's inventory management features.

I don't think technological illiteracy plays a large part here, Aaron exploited a flaw in JSTORs ratelimiting system and continued doing so after being blocked several times by JSTOR administration. After that didn't work out he broke into a server cabinet at MIT.

Does that sound 100% OK to you?
Yet it's a Mercurial repo. Not a big deal and I have nothing against Mercurial, but something that's marketed with "no dependencies" would be better off if it was on Git - way more accessible.
VolumeDrive - what a surprise. They're a disgrace in the hosting world and I strongly advise anyone against using their services (they don't pay their bills for DC space, equipment, etc, http://www.webhostingtalk.com/showthread.php?t=1296858).
Apart from the great amount of fun you can have playing with it, are there any other (more useful) applications that can be developed from this?

I'm thinking along the lines of how it could make the layout of articles on the web more fluid. The algorithm is currently limited to fitting the text to the wave function on the right side, but could be expanded by adding alternating amounts of spaces on the left side.

Big problems, create big opportunities. Some of the developments that may occur to address this issue over the next 10+ years:

- Development of a robust water entitlement exchange
- Decoupling a water right from the land to create a more tradable asset
- Regulation change to allow for water leases
- A shift away from growing 'thirsty' crops in drought-prone regions
- Decentralization of water treatment plants to reduce distribution costs
- Increased use of grey and recycled water in the home
- Pricing changes based on its use within high water use industries
- Increased use of GM crops designed to require less water
- State-sponsored overseas farming specifically for US import of thirsty crops
- Less water exporting occurring. I.e. selling thirsty crops to China

And I'm sure, much, much more.

To the point of EV certs, if you haven't checked in a while the browser vendors have _really_ started to de-emphasize non EV (standard certs).

Here's a visual comparison I put together:

https://www.expeditedssl.com/pages/visual-security-browser-s...

How you feel about this probably centers around whether you view SSL more as a cryptographic means of securing a connection (stopping traffic snooping) or if you view the SSL+Browser iconography as a means of site identification (stopping phishing attacks).

The blood vessels all run within the scalp, which is part of what helps it be loose. Some run up the side and some come out next to the eyes, and nothing has to go through the top half of the skull.
Aaron did what he did knowing the consequences, my best guess is that at some point after he started regretting his decision.

This is how the world works, if you make a bad decision you'll have to live with it... Or not.

tldr; you tend to remember a) things that interest you and b) things that you repeat.

I am also very fond of reading but I usually read fictional books. One of the things that
I have noticed is how I tend to remember the plot even after a long time. For instance a few days back
I was reading a Sherlock Holmes story (the speckled band) after about a decade and I was surprised at
how well I remembered the solution to the puzzle. Incidentally I have also noticed this on previous occasions
like when I turned the pages of count of Monte cristo or the three musketeers or other books that I enjoyed back in the day and I instantly found myself "in the world" when I expected to be "out of place".

On the other hand I tried reading a Shakespeare play that I had the opportunity to read before in my high school
and I didn't remember it quite as well. No wonder there because I never enjoyed his work even though I tried many times. So my conclusion is that I tend to remember things that I like. Even if I forget them I get up to speed very quickly.

But the problem is there are things that are good for us that we might not enjoy. I don't particularly enjoy reading non fictional books but I know it is important that I read them if I want to learn. So I read them slowly making progress each day. Often taking handwritten notes and re reading things that I found interesting the first time around.

I have this theory that if you read anything some parts stick in your brain and they stay with you forever. Even if you feel like you have learned nothing you always take something with you. It could be a changed outlook on the subject or maybe a better understanding but you never leave empty handed if you read. I have no evidence to support what I have said though it's just something that I have noticed in my self :)

Aaron did what he did knowing the consequences, my best guess is that at some point after he started regretting his decision.

So, your "guess" is as good as mine, or any of my fellow armchair analysts on HN? Are you sure Aaron even considered you a friend?

Or perhaps, you were just trolling HN, eh?

So by what you wrote, it sounds like they're related, but a completely separate concept. Where can I find an intro to transducers that's readable for beginners? I don't know what "list monad Kleisli category" means. Searching for "transducers" came up with a physical transducer.
Couldn't the compiler get around that by introducing a boolean variable that is set depending on the branch of the if statement taken, that it checks before running the destructor?

Although this starts getting really messy.

I can't edit now, but I thought by non-green, OP meant a self-signed certificate. Didn't realize OP was referring to EV certificates. I don't have a problem with buying from domains without EV certificates as long as the certificate is valid.
I know in Berkeley the reservoirs are all covered over. So if anything, moving water down to here probably prevents loss. If you read the article, a lot of water is kept near the source as well, like Hell Hole reservoir, and only let out prematurely if the reservoir is near full. So I'm not sure what you are complaining about. Are you claiming the water should be used in the north instead of the south? Northern Cali is already wine country, e.g. Napa, so it is already in use. There isn't any way to move the southern agriculture businesses there.

It's been mentioned once, but I think the Minds from Ian M. Banks' Culture series is a quintessential example of benevolent A.I.

To maintain a post-scarcity society, humans have turned over control of to the Minds, "hyperintelligent machines originally built by biological species which have evolved, redesigned themselves, and become many times more intelligent than their original creators."

Minds manage everything from resource allocation to war planning. They also control all of the technical, day-to-day operations. Still, "the essentially benevolent intentions of Minds towards other Culture citizens is never in question. More than any other beings in the Culture, Minds are the ones faced with interesting ethical dilemmas."

You could consider EV certs as an economic attack by the Certificate Authorities and Browser vendors against phishing operations.

As a baseline, it is fairly difficult now to receive a certificate for any well known company, charity or government entity. For example, even a standard non EV request for something like 'C1tybank.com' would be flagged for manual review and rejected.

EV cert requests just up the amount, types and means of communication that must be done which (hopefully) raises costs more for phishers attempting to setup hundreds of scam sites than legit purchasers.

One thing I haven't seen the popular media take Home Depot to task on is: Why didn't they review their security after the Target breach?

The Target thing was announced in December last year. Home Depot had between then and April-May to do a full review and see if they too were vulnerable. Not only did they fail to do that, but they failed to find this issue for 5 additional months(!).

I liken it to being a miner, watching the canary die, and then continue to work. Then you're shocked shocked that there was poisonous gas in the mine when you "found out" hours later.

I just looked up "Gross negligence" (per corporate law) and this seems to wholly fit. This is almost textbook Gross negligence but yet not a single prosecutor in the US has gone after Home Depot, why is that?

In fact it seems like Home Depot will walk away from this almost cost-free, no fines, no prosecution, no significant costs (the "free monitoring" is stupidly inexpensive, plus nobody actually utilises it), and only minor negative PR.

Maybe states should just fine companies 10c for every Credit or Debit Card number lost. That's a 5.6 mil fine for Home Depot, maybe then they'd take it more seriously.
Why would you say that?

That website is firmly optimised for large screens, certainly not phones. It’s not even a little bit responsive. And it still manages to have too long line-lengths (though I do like it’s hierarchy and use of white space).

Former YouTube developer Chris Zacharias has an informative story of the effect of reducing the page size from 1200 KB to 98:

>When we plotted the data geographically and compared it to our total numbers broken out by region, there was a disproportionate increase in traffic from places like Southeast Asia, South America, Africa, and even remote regions of Siberia... Large numbers of people who were previously unable to use YouTube before were suddenly able to.

Granted, that's a bigger leap than the one that made you cringe, but if it takes 2 minutes to load the new version in these areas (the number Zacharias gives), cutting 40 KB saves them 30 seconds.

"So if you do go for an EV cert, go for the one that has the best listed uptime on it's CRL or OCSP servers."

http://uptime.netcraft.com/perf/reports/performance/OCSP

How is the above bad advice, and not answering the context of the question? What other possible qualification is there for "best" EV certs? They are all "green bar". There is little else to them except price differences.

His customers are going to want a responsive page load time, none of them are going to pull the certificate to make sure he went with a DigiCert EV instead of a GeoTrust EV.

You're forgetting latency. Speed of light isn't getting any faster.

With all the round trips that TCP/IP makes, and the congestion control and TCP slow start (especially if your connection occasionally drops packets, which often happens on mobile / wireless connections), surprisingly little additional data can add a surprisingly long delay. Especially considering the multiple round-trips to third-party servers often required by JS libraries.

If net neutrality falls, what happens next?
This is one of those things that we're just going to have to wait and see about, but I can't get the question out of my mind - if the FCC chooses to back the ISPs, what happens next?

Is a hacktivist group, deciding that the internet shouldn't be turned against it's users, going to DDoS the root DNS servers? Is everybody going to just hold their breaths, and continue with business as usual? Will a significant number of developers jump ship?

What do you think?
I think it's getting better. In Moon (2009, also spoilers ahead, depending on how you interpret it) the AI actively helps the protagonist. My dad kept wondering when the AI would go rogue or try and stop the protagonist, but the AI never does. It helps the protagonist because that's its purpose. It quips numerous times throughout the movie "I am here to help you."
Elected representatives in America often portray themselves to uphold American dream (http://en.m.wikipedia.org/wiki/American_Dream) ethos. But in practice they support policies that go exactly against that ethos and support gatekeeper policies like net neutrality. Yes it is a global issue. I am putting forth an argument in an American context.
Any dynamic language should do, kind of :)

For example, the following code needs Higher Ranked Types to typecheck:

id :: forall t. t -> t
id x = x

-- mk_pair's type is a rank-2 type, because its
-- f parameter is a polymorphic function that gets applied
-- to different types inside mk_pair.
mk_pair :: (forall t. t -> t) -> (Int, String)
mk_pair f = (f 10, f "str")

a_pair :: (Int, String)
a_pair = mk_pair id

But it can obviously be written in an untyped language if you wanted to. Just erase all those type annotations:

function id(x){ return x}

function mk_pair(f){ return [f(10), f("hello")] }

var a_pair = mk_pair(id);

The deal with higher-ranked types is basically a tradeoff between the flexibility of the type system and the power of type inference. If you restrict yourself to rank-1 types (that is, none of your function arguments are polymorphic) then the compiler can infer all all types in the program without you having to write any type signatures. If you want to use higher ranked types then the compiler can't infer everything anymore so you might need to add some type annotations yourself.
