For regular doctor's appointments, I don't go to the hospital, I just go to my doctor's office.

I can imagine pretty well. When things are set up with good insurance coverage, it's hardly any different than what you described, maybe with the exception of preferred networks, but in my city I've never had any doctor fall outside of the preferred network for my insurance anyway. Everything is either covered from the insurance or you get a straightforward bill, and even then you can get an HSA to cover your out-of-pocket expenses with some insurance plans. I've never had to deal with insurance paperwork either, aside from collecting my insurance card from the mail and presenting it at the doctor's office. It can easily be much, much worse though.

So...the way that you do that in Maven is to create a plugin, which is very easy to do. There's your full flexibility, as soon as you want it.

Your plugin has to play by the rules, which is a good thing.

Maven's useful for more than the beginning of a project. If you're working on real-world software, you're probably not the only person who has to understand your bespoke build, if that's the way that you've chosen to go.
In a unsalted system, let's say your password is "hello" and my password is "hello." Your hash("hello") will be same as my hash("hello"). When I see your hash is same as mine, I know your password is "hello."

In a salted system, your hash("hello" + salt1) != my hash("hello" + salt2), and I have no way of guessing your password since the hashes are different.
Thank You HN; Promoting apps is hard, but You’re all awesome
Oh, i'm a jackass. thanks.
Alright guys, let's save the economy! This was the perfect amount of motivation for me.
It's interesting that the only 3 self-made billionaires under 40 are in tech - Larry Page, Sergey Brin, and Mark Zuckerberg. The fact that 12 of the top 100 are Russian is rather striking to me as well.
If you click the little "i" in the top right you can get the full methodology. In there it explains why Bloomberg the person is missing

>Bloomberg News editorial policy is to not cover Bloomberg L.P. As a result Michael Bloomberg, the founder and majority owner of Bloomberg LP, isn’t considered for this ranking.
My first programming gig was an internship at Vigil Games when I was 20. I had an awesome summer there and worked with some amazing people; hopefully those who were still at the studio will find something soon.
Interesting, no unftly not that I know of. Maybe if you went with one of the more advanced packages. The Contact Manager edition is pretty limited.

You can pull profile photos of theirs from Twitter, LinkedIn, or Facebook though. But obviously those images aren't yours to choose.
Does it matter? In this case the alterior motive (Kim protecting himself) happens to coincide with privacy, becuase if your information was not private than Mega could know it, which defeats the entire point of Mega being protected by not knowing it.
A map of every person counted in the 2010 US Census
The key derivation function's purpose is to take a long time (CPU time) to compute an output key given a password input. The combination of dangers here is that the KDF is too fast (doesn't take enough CPU) AND the output is the same per user.

What we're trying to protect against is someone in possession of the data (such as Mega themselves, or anyone working for them, or hacking them, or seizing their assets, or just someone over the internet making an offline attempt against an account after discovering the auth hash) from making a brute force attempt to learn the plaintext content of the accounts.

So to help me crack accounts, I could make a database of outputs from the KDF, with every password combination pre-computed. "Start with "aaaaaa" as a password, and go all the way through "ZZZZZZ" out to some number of characters. The database would have 32 output bytes per entry. The first 32 bytes would be the output of "aaaaaa" through the kdf, then "aaaaab", and so on.

If my math is right, going out to 6 characters using letters numbers and punctuation, the database (probably just a file really) would be about 5 TB in length, and based on my single slow CPU's AES speed, would take about 99 CPU days to compute. Of course if you have 100 CPUs (or EC2, or a botnet) you could have it done in time for dinner tomorrow. Or just wait because someone will likely precompute one you can bittorrent in the next few days.

So, if I wanted to make a brute force attack against Mega's database of users, I would use this pre-computed database, reading it sequentially from disk, taking every 32 byte section and trying it as a key to decrypt the next layer of keys for a user. My CPU could likely check answers faster than the data would stream in from the disk.

So I would be able to brute force any combination out to 6 password characters in a few minutes using only the spare hardware sitting around my office and unoptimized code. Imagine what NSA could do.

So, finally getting back to answering your question. If the salt were used, then I couldn't pre-compute the KDF output. I would have to do it separately for each user. So then my attempts would (again on my weak CPU) proceed at only about 520 attempts per second. That's still about 500 times to fast. So, the design needs both a slower KDF, and salt. :)

Trivia: Want to time your own CPU and how many AES cycles it can do?

$ openssl speed -evp aes-128-ecb
Doing aes-128-ecb for 3s on 16 size blocks: 102358287 aes-128-ecb's in 3.00s
>>> 102358287 / 3 / 2**16
520

Hopefully that makes sense!
And which of those falsehoods applies here? I might be a bit thick, but just stating the falsehoods does not imply that our base temporal objects should be full of presentational properties. Or does it?
Suprised to find I can access blogs without signing in. I used to enjoy Quora. I would browse, then sign in and comment when I felt I had something relevant to add. Unfortunately the forced login to view content and Quora automatically posting recently read articles onto Facebook made me stop visiting.

These blogs won't draw me back. Many topics have aggregators you can submit you blog to. I would imagine building a readership on Quora will be no easier than running a self hosted blog.
given that its from bloomberg.com maybe this is intentional :-)

> I don't think socialism or a high salary is necessary to have a higher quality of life over the long term

Agreed, though this really only applies to younger generations. A large portion of our currently unemployed are in the 40-60 year old bracket (aging population). It's unlikely a lot of these people are going to strike out into new careers. I'm sure some will, but it doesn't seem enough to make a difference. So we need to figure out how to care for them. And if we set up a social safety-net for everyone in the process, all the better.

> As technology increases abundance, material goods will become cheaper.

Possibly. Innovations like 3D printing are particularly interesting. As they become more sophisticated, predominately foreign manufacturing could come back home, albeit in the hands of "robots". Hopefully this would lower costs of goods, but the steady upward march of inflation leads me to think that's unlikely.
Why does the link go to directly to self made, energy billionaires?

>When you consider just how much money $10+ billion is, from an ethical standpoint, does any individual deserve to have that much money/power?

How can there be an ethical standpoint to an arbitrary amount of money without the context of how it was obtained? 10 dollars would probably fall within your expectation of an ethical amount of money for a person to have but if they obtained it by mugging somebody else is having even 10 dollars ethical?
"They deserve every penny of it?"

I'm sorry, but there's no way that any person's individual contributions to society are worth 3-4 orders of magnitude more than most other people's. And if there are such individuals, they are the Teslas, Newtons, Einsteins or other true geniuses whose ideas have shaped the world and opened up new possibilities - not the oil magnates, plutocrats or Wall Street bankers that make up most of this list.

The only way one could argue that all of the uber-rich deserve all of their money is if you subscribe to an incredibly simplistic, idealistic, optimistic Milton Friedman-esque economic and political philosophy which assumes that the earning of income directly corresponds to value added to the economy and society.
AirB&B is increasing the supply of housing in SF. Prices should fall in that circumstance, except that city policy has been dramatically restricting the supply otherwise.
Not really trying to coin the term, I just gravitated to it when I was thinking about this topic. I've actually been thinking about this for a few months and two thoughts have dominated my mind:

1. As a UI designer, I love flat design. Probably that's partly due to it being new and refreshing, but I do appreciate cutting down the visual noise to a minimum and focusing on the content.
2. As a UX designer, flat design is extremely problematic for all the reasons I discussed in the post.

I'm happy this has started such a discussion and hope it can help other designers form their own opinions with this whole flat movement.
Except this wasn't about illegal collusion to stop all cross-company hiring. It was (at worst) a potential antitrust issue related to anti-solicitation.

What you're describing is a conflict of interest that exists at the heart of capitalism. Owners want to pay less, employees want to make more. I don't disagree with labour fighting for their interests. But I don't think this was particularly appalling or immoral from the owner's POV.
My 'irrational' fear exists because of facebook's constantly changing uses of our data. When they began and we all started liking things we didn't know these same likes would be used for marketing purposes. We didn't know they would be used to sponsor ads. They went from a social network for people to a social network for companies. I agree with you and I do understand that I choose what is public, yes that's great; but how about the average user? Facebook makes money by selling it's users' data to companies. If everyone was private they wouldn't make any money.

This open graph search will be great for marketing purposes, and a silly tool for us users. I guarantee there are going to be some serious consequences of companies/governments having the power to instantly search and sort billion's of users' data. And maybe you'll say that some great findings can come from this search; maybe we can learn more about humans and societies with this tool? Maybe, but I believe the cost outweighs the benefits.
It is correct for a request for a page named "error" to result in a 200 OK status meaning that the page named "error" was successfully retrieved.

It would not be correct for a request for a page named "error" to return 404 Not Found if the page named "error" was retrieved successfully.

It would also not be correct for a request for a page that does not exist to return the page named "error" with a 200 OK status.
I'd take the 6 lines of vanilla javascript any day over loading the full jQuery library to get away with writing only a single line. If jQuery isn't use anywhere else on the page, that is.

Of course, but this is not what i'm saying...

You can't wait, let's see,... six months?, eight months? You can't wait a year until the baby is born and someone can care or him? You really need to put this pregnant woman in jail Just Right Now?

>Quora’s new blogging tools will appeal to two demographics. The first are people without any web celebrity already. Quora’s Kah Keng Tay writes that Quora blogs suit people who “(1) don’t have a big, established online presence already and (2) don’t want to do the time-intensive, heavy lifting of marketing their blog and slowly building an audience.

It's a double edged sword, since (1) might accelerate your path to internet stardom by a little bit, but by taking (2), you lose the control and a large part of the benefit that comes from achieving internet stardom (if that's you thing) in the first place.

If you are looking for marketing enhancers for your online blogging, you're usually at least partly considering some ends beyond increasing eyeballs (affiliate ads, consulting leads, ebook sales, etc.) [1]. Using Quora as your primary platform puts a damper on the output of these 'ends', and using it as a secondary "Crosspost" location fragments your audience and increases your labor overhead anyways.

Addendum: Benefit (2) is largely moot since its upfront cost reduction for a blogger is not going to be significantly larger than Tumblr, if at all.

[1] If you weren't at least considering these things, then you'd probably be happy staying on your own domain.

The lifestyle business prospect is interesting, as mentioned in that Forbes article that hit the front page[1], there is the possibility for many to start making a steady living in the sharing economy. I'm involved with a business working in the arena, and the possibilities are intriguing. Whether or not it becomes a sustainable economy for the longer term is still pretty up in the air

Yes, yes they do.

That money isn't sitting around, it is paying for things. I point you to the misguided luxury taxes put on yachts because people buying them "deserved" to be taxed more. Well, all it did was ruin the yacht industry in the US and put a lot of people out of work. These people were being paid good money. That is grotesque and wrong.

There is no ethical argument for taking money from billionaires in higher share than anyone else that doesn't come down to envy. Limits on individuals place limits on society. Why hire more people and expand when you cannot enjoy the fruits of the work?

Perhaps it is an indication that Cuba is doing it very wrong.
Because of external costs, like healthcare, and training, one employee working 40 hours has a lot more utility than 2 working 20. This is especially true with the large differences nn productivity from person to person, especially in software.

This is also why people crunch, and demand over time. Productivity goes down, but each individual hour worked is still better than getting some fool off the street.
Also striking is how the Russians made their money: energy, steel, metals, and... uh... "being friends with the people in power when the Soviet Union fell".

It's all very late 1800s.
Recently 4chan had an excellent monetization idea:

Require passing a CAPTCHA in order to post.

Allow users to buy a code that will let them post without passing a CAPTCHA.

Accept bitcoins to avoid payment providers' prejudices and help users remain anonymous if desired.

Of course, you want to add some limits to discourage people from publishing their codes. For example, a rate limit on posts (with a slightly more generous burst allowance, e.g. you get 10 CAPTCHA-less posts / hour, but if you don't use them, up to 100 CAPTCHA-less posts are automatically "saved" in your token's reserve). Or a limit on the IP addresses, e.g. whenever a code is used on more than one or two unique IP's within a short time, lock it out. And of course the gold standard: Manual monitoring for spam, illegalities or other ToS violations, punished by account cancellation (and referral to law enforcement for extreme cases).

You could sweeten the deal with custom markup: Make posts by paying users be a different color or something, to show they support the site. Or if users have a traditional forum account (as opposed to anonymous posting), add an icon or something to their profile.

If I was implementing this, I'd have three tiers: The "cheap tier" (around $5) for just CAPTCHA-less posting. The "medium tier" (around $15) for CAPTCHA-less posting and a note in your profile that you're a supporter. The "high tier" ($40-$60) for different-colored posts.

If you want to know why I suggest three tiers, Joel on Software has a post that explains it very well [1].

I managed to do my entire Java career by dodging Maven but I'm now learning Clojure and I really like the language but, sadly, I'm not fluent enough in Clojure to do everything "by hand" so I'm using Leiningen...

We posted on HN for exactly this type of constructive criticism (though we do hope that there are a few quiet users who are enjoying our app and don't feel the need to post a plain back slapping comment that isn't really part of the spirit of HN anyway).

Privacy is something we take very seriously at OpenSignal. For one, we watched CarrierIQ get torn apart[1] after it came to light the types of data that they were collecting of their users. Its obvious to us that if we ever abused our user's privacy the same thing would happen to us, so not only do we consider ourselves moral people there are clear market forces from preventing us from using your private data, which might be more reassuring to some.

We also only look at data related to your wireless service e.g. signal strength, data speeds etc and always anonymize it. It's worth remembering that not too long ago studies found that 50% of top android apps were tracking and collecting personal data[2] such as IMEIs, phone numbers, sms etc and these are not crowd-sourced data gathering apps, this was a random sample of the top 30 android apps at the time of the study. With that in mind, we don't begrudge anyone who wants to check our privacy standards are up to scratch.

WordPress and the GPL, round two
"the" GoDaddy fiasco. Heh.
I have previously submitted bug reports when the crash happened through regular Android bug reporter. I just gave it a try and now it doesn't crash and start time has gone down too. It feels much more smooth now. Good work. Two other things that I want to say are as follows.

1. The app allows you to swipe among screens (Dashboard, Test, Stats, Coverage, and report) but once you are in coverage/map section swipe among screens doesn't work, instead it pans the map. May be a lock should be placed in map screen to have a consistent swipe experience.

2. I am not sure how stat settings work. I use Nexus 4 with Straight Talk/ATT. It is a prepaid with $45 for everything unlimited. I pay on 7th of each month. Allowances and Traffic settings in both Contract and pre-paid revert back to default settings. I can't change top-up date in pre-paid settings. Data/Call/SMS monitoring settings can be more intuitive.

Thanks for coming over here and answering questions.
I've been doing "almost flat" for years because it's the simplest expression of a design without gutting affordances.

Things that are interactive look interactive, and these attributes are only used for that practical purpose and never for pure decoration.

I really don't understand why this is even a debate. Do we need a daily post talking about how Apple's overwrought, realism aesthetic is tacky (it often is) and how flat design is too flat (which it is)?

This issue has officially reached dead horse status.

I've repelled off wind turbines inspecting 40 meter blades and they are massive. I hope they really get their process down for mass production, because many of these blades are low quality and need to be replaced under warranty. Ice is obviously a major issue with this size, for both the balancing of the turbine and for a potential hazard to passers by.
I enjoyed the article but I feel it overlooks one of the biggest reasons to use something like maven:

It gives us the language to efficiently reason about and discuss build concepts with colleagues.

This is a big thing, think about the most recent new starter situation you experienced, about how communication of these common build tasks was expressed. Chances are if it was with a more composable tool, the discussions were fairly detailed, the words 'just like' frequently appeared. If it was with a more rigid tool, the conversation would have been in terms that tool commonly defines.
So, for the same profits, we had a stock price of 420 this time last year and ~515 today. So, you automatically assume 420 was the right number and 515 is not, and that it will head toward what you think is the right number? Got it.
According to Wikipedia, Rockefeller is widely considered to be the richest person ever, but I guess this is interesting to me because the Walton heirs themselves are still making billionaire lists. But that's a good point. I wonder what the total Rockefeller net worth is among all heirs today.

Inflation is irrelevant over the long term. The real cost of goods after adjusting for inflation has gone down for the past few hundred years. It's of course a problem, but not because it will increase scarcity.

As you mentioned, the real problem is the aging and obsolete workers in the short term.

What would Dotcom gain from having a weak crypto system. Plausible deniabilty will work up to a point, but the government can still subpoena his encrypted data, crack it themselves, then require Dotcom to comply. And if Dotcom actually acted (or even accessed) the data, then he would through plausible deniabilty out of the window by demonstrating that he does have access to the data, in which case the entire exersise in creating the cryptosystem is pointless.
