I can tell you the book that got me excited about quantum computing: The Fabric of Reality, by David Deutsch. It ranges over a much, much wider field than just QC, but if you want to understand how one of the best theoreticians thinks then there is no better book. Comprehensible by a smart 13 year old (as I was when I read it).

If you have some mathematical maturity, I heartily recommend Quantum Computing since Democritus, by Scott Aaronson. The book's web page is at http://www.scottaaronson.com/democritus/, where you will also find freely available the lecture notes on which the book is based. Scott Aaronson's blog (http://www.scottaaronson.com/) is also a very valuable source of insider knowledge on QC, much of it targeted at a broader audience. I recommend his "Ask Me Anything!" posts for a good breadth of topics and technicality.

Schrödinger's Killer App by Jonathan P. Dowling is a pleasant alternative to Fabric of Reality if the latter is too out-there for your tastes. No equations, but it definitely has some conceptual meat on it.
It was Splatter Consulting in RTP. They don't exist anymore. They shutdown probably 7 months after I walked. This was back in '98. The deadline "we couldn't miss" was to build a product. This product would move them from consulting to a product company. It was actually a neat product. Had to do with camera optic systems. Writing software that interacts with hardware was really cool. It still is, but I've gotten lazy and enjoy being wasteful using a whole byte for a boolean and what not...

After I left, it was probably 4 months before everyone but the 2 sales guys and President were laid off. They lasted 3 more months before folding.

I actually left a good job to take this one. Lured me away with money :) Like I said - young and stupid.

Absolutely. Everything else mentioned on this page is palliative. This addresses the root cause.

Well, closer to the root cause. The root cause is culture.

(Well, actually the root cause is human nature, when placed in certain circumstances. But that's too theoretical to be useful in political practice.)

To the degree it is about a credential, Western Governor's University is a reasonably priced option - http:\\www.wgu.edu

While MIT might offer good courses, they're designed to be tough for a very select group of the best prepared students even with the support resources such as Teaching Assistants and labs and peer students and professors with office hours that are accessible only on campus. Without those, it can only be tougher. In my opinion, tougher to the level that a multi-year project has a low chance of success even for a person of above average motivation and intelligence.

Personally, I think a CS education from an average school will probably better prepare anyone motivated enough to have a chance of completing a full slate of MIT courses as self study. You can always get a graduate degree someplace more selective.
Great post. I totally agree, and it is for these reasons I loathe anyone who defends the actions of the USG/NSA.

I also find it incredibly naive of others who make statements, here on HN and elsewhere, that the US is NOT a real tyranny as compared to others like Russia/CHina/Whatever.

Sure it is - its just much much more successful at population control.

I like Spark over Hadoop just from an interface point of view, particularly the ability to just start up a (Scala) shell and start playing around. Hadoop can be very effective, but even getting "hello world" to run requires an intimidating array of setup.
Breaking into growth hacking
I have to say that I think the big takeaway is radically different. Riding off the marathon analogy, taking vacations is critical to prevent burning out. In the long run it will keep you more productive and in turn be better for the company.

Tim Ferris has some great things to say, but there's also the inherent risk that when working alone and taking a vacation, no one else is there to watch your back.

Culture at some companies is definitely more what like what you described, particularly at finance firms, but there are definitely cultural shifts happening right now as less college grads are going straight to finance every year, allured by the perks that tech firms have to offer such as unlimited PTO in some cases.

It seems like your situation is very different from that though. Working at a small startup is really hard, particularly when you already have a family. I wish you and your startup the best of luck in the coming year.

Not if you want a CS degree, which WGU doesn't offer (WGU does offer a variety of IT degrees, which may be an acceptable substiture, or even the preferred option for some people, but its certainly not even remotely the same thing as a CS degree.)
There aren't great simple solutions to this issue AFAIK, but here's my take since I had a similar android app feature:

Want to find friends using contacts in phone:

Snapchat solution: pass number(s), return user info if number(s) in DB. +rate limit

Problem: rate limiting is not enough in this case.

Other solution:

Save contact lists of two users. If user requests friend look up, compare contact lists.

Basically return user info if the two numbers have each other in contact list, thus a verification they know each other.

Duping the snapchat system with the old method won't work, but drawbacks are that you have to store
a copy of user sensitive information, and if that gets out from your servers in some other hack, that would be
really bad, as bad if not worse than the first since it has more information, i.e. who knows who. Also less efficient,
space and time wise.

It's entirely possible you're just screwed in whatever county you're in, but I don't know how exhaustive eHealthInsurance really is. I didn't use it, though it does show my new off-exchange plan. I already knew which company I needed to go to since I wanted a Blue Cross or Blue Shield plan.

What I would do is assemble a list of every health insurance provider in New York and directly visit each website and/or call each company to see what the options are in your area.

I'd also check with an actual insurance agent who might have a clearer picture of the situation where you are. Even though I knew I needed to go to Regence Blue Shield and that they have coverage in my county, I still went to a local agent to help me make sure I got everything right.

EDIT: NYT actually did an article on this in October[1]. They point to eHealthInsurance, but also GoHealth.com, which I haven't seen before.

Would be extremely interesting if this worked on a macro scale. They are floating nuts and bolts with a small desktop device.

I'm also curious about power draw/requirements.

Apparently they are using arrays of Langevin type sandwich transducers to generate the ultrasound, of the type used for industrial cleaning applications (example http://www.ipfonline.com/products/index/langevin_type_sandwi...).

What happens if you have an array 2x2 meters? Or 20x20? Does the wave have to completely encompass the object to act on it, without exception? In that case we may need to revisit the lower frequencies and attempt to move balloons, etc. Some relation to the resonant frequency of the object being targeted may be involved.

Well, I'd disagree with at least two of your premises:

1) That the proposer of the question often understands the job. (by which i mean, in real world interviews. I'm not commenting on the specific poster).

2) I am not saying that I couldn't do the question, per se.

On the contrary, my professional work shows not only that I can do the question, but that I've probably done it innumerable times and to the standard of (and sometimes greater than) other professionals.

The subtext of my response to the bond question shows that, in an absolute juvenile sense, I "know" the answer that's being looked for because I've notionally been trained as en economist. Which is to say, I am aware of the rote learned current models/theory.

I'm saying that I probably couldn't answer it in the interview environment in the way that most interviewers would deem "acceptable" or "right".

Why? Because I both haven't memorized Bayes theorem, and wouldn't accept there as being a simple probabilistic interpretation applicable to real world problems. Now its true, I could probably attempt to re-derive it there in the interview from some even more basic understandings of probability, but is that what interviewers want? I'd almost certainly offer the answer of "Can i look at the two sides of the coin?" or "the probability is either 0 or 1". And then we'd go down the path of probability interpretations, and then only after they made it clear that they wanted a Bayesian approach, we could start heading in that direction. Is that what they're looking for? I don't think it is. But they are all valid responses.

I think they want someone who has remembered Bayes and its application recently and then just applied it. I think in the bond question, they want someone who has rote learnt some economic/finance theory. And I think the worst aspect is that the stronger candidate, who pauses, who thinks, who questions, and who doesn't just go down the regurgitated answer will probably, in real life, be marked as the weaker candidate.

And I'm also saying this as someone who is already employed, being paid and and working professionally on things the questions are supposed to be screening for. So while the original poster is in a position of authority to speak of such things, so am I.

Are you familiar with Project Euler? I've completed many of those problems as well, but I would never expect myself or some other candidate to be able to do them spontaneously in said interview, or think worse of them if they couldn't. And if they could do them, I don't think that would be an indicator of very much more than the fact that they happened to be working on said problem recently, had just taken a course on said problem, or had just been doing interview questions for my field.

You seem to take position to defend the snapchat stance ... I read it as a validation that there is a tradeoff made by design, and anyone caring enough about privacy wouldn't have implemented the feature in the first place.

Privacy doesn't have to be the goal of every service, let's just admit that it not a main concern of Snapchat either.

Of course Facebook also has a lot of leaky behaviors concerning finding friends and friend suggestion. They also value service growth more than privacy, and that's their right.

With the inexpensiveness of electronics today, why haven't we moved from a mechanical "password" (the height of the pins) to a simple electronic code programmed into the key?
Some interesting use cases are also described on Cloudera's developer blog, at http://blog.cloudera.com/blog/2013/11/putting-spark-to-use-f....
This goes against all the advice I've seen elsewhere; we push our feature branches all the time, and sometimes pull from each other's if we're working in overlapping areas, so we need to not rebase them.
Since this will end up being a sort of "new Internet", I hope they start by building this one with security in mind from the ground up. We don't want to end-up with a next-gen Internet, that's just as broken as this one, security wise, especially since you basically have to have access to someone else's phone or computer, to get in the network.
Transparency rocks, but this feels really ad hoc.

I mentioned on the Stripe thread: if you get tired of the corner cases and human nature not handled by their or this hackery, have a look at combining email aliases or filters on the front end with Best Practical's "Request Tracker" on the back end.
There is a good chance that a failed password attempt is an indication of something shady going on, so exponential delays are appropriate.

How are you going to tell the difference between an API hit for the phone number of someone you know vs. a phone number you made up? Or are you going to increase the delay after every query? If you do that, then the "find friends" feature will just break down for people with sufficiently large contact lists.

Maybe don't reveal the username unless that user has your phone number in their contacts? Sounds good. But how are you going to check? Snapchat would need to store every user's contact list, which HN also considers unacceptable. Hashing is not an effective mitigator here because it's so easy to bruteforce the space of 10-digit numbers.
The entire thing is opt-in. Nobody is subscribed to anything by default — if you want to listen in on the mobile team's archive, you can. But you don't have to.

This reduces inbox noise because it increases the percentage of emails in my inbox that people expect me to read completely and/or do something about. No more "might as well just CC Ben for the heck of it." Those goes elsewhere, for me to quickly browse the subject line if and when I choose.
> a lot of companies don't care, these are the rules and you accept them or not. Most people accept them - they feel like they have to.

A 322 word blog post, no apology and 6 instances of the word 'abuse'.

The PR message that Snapchat just sent is not a good one. Their target demographic may not care much, but at the end of the day, this brand just dropped a big ball and lost an opportunity to build something better.
In Switzerland, you buy your health insurance yourself using post tax money (employers can't provide it); like ACA, they can't discriminate for pre existing conditions and it's mandatory to have insurance. Everyone is pretty much on the same footing.
You may be right. Certainly the gay rights movement has succeeded beyond my wildest hopes or expectations during a period of generally right-wing dominance amd stalemate (the democrats have only had two years to pass legislation since 2000), and now it looks like the war on drugs might collapse. We seem to be enjoying one or two tectonic shifts in politics every decade right now. Amazing times.
I'm probably a bit weird, but all the computers I own now are macs... and I run windows 90% of the time on pretty much all of them. OSX really is pretty, and I like having a unix with a nice GUI, but when it comes to usability I think OSX just isn't very good. Task switching is awkward. The dock looks nice, but compared to the taskbar it's not very functional. Maximizing windows often ends up with surprising results. (Does it take up the full screen? Or does it just vertically maximize? What happens if I try to unmaximize?) Useful keyboard keys are mapped to weird things (for instance: home/end moving to the beginning/end of a document instead of the end of a line. I need to go to the end of a line about 100x more often than I need to go to the end of a document).

Also: animations. They're great for demos, but when you're trying to get serious work done they're irritating and you can't turn them off without some commandline-fu. I get the impression apple pretty much will always prioritize gloss over functionality.
Developers underestimate their value and their ability to say "no". If you are a productive coder, the job market is great. If you take vacation assertively (say, six weeks a year) bosses simply can't afford to object.

Ah, I did not realize it was some sort of syndicated post.
All of these physical analogies are completely inapplicable.

When you send a request to a machine owned by a person and it responds with data that person doesn't want you to have, it is not your fault for sending the request - EVEN IF YOU KNOW/SHOULD KNOW/COULD REASONABLY BE EXPECTED TO KNOW/ETC THE PERSON DOESN'T WANT YOU TO HAVE THE DATA.
I agree that the difference is important to the degree that the concern is over education rather than about credentials. That's why I also mentioned the value of a CS degree from a less prestigious institution when the student is highly motivated.

But if we're just talking about credentials, then a relevant degree plus experience gives anyone who wants to hire the OP a green light.

> The question is, "Who should have to pay for [large amounts of] vacation time?"

An utterly meaningless question. In your "modern" contracts-only world, it's still the employers who pay for it, because the employees would earn the money for between-contracts "vacations" through sufficiently high contract rates.

> Also, I don't know if you've ever been involved with a small business before, but "can't afford it" in that context usually means "literally do not have that much money"

The technical term for a business incapable of paying its employees is "bankrupt". Keeping such a business running is, in many jurisdictions, a crime.

Not granting adequate time off is effectively the same as failing to pay wages, and a business that cannot do it needs to die sooner rather than later.

> Somaliland receives its Internet connection via microwaves across the desert from Djibouti.

Surely the main way people access the internet is through 3G either directly on the phones or on mobile broadband. When I was in Hargeisa in 2008, 3G connectivity was common, and I would assume that it is still the case (though its possible Abaarso doesn't have a very good mobile connection).
I think it's common to use "hypervisor" to refer to "hypervisor host" (and usually not "hypervisor software").

I've been hearing this usage more often these days.
I've largely stopped using Uber in place of Lyft and less often Sidecar. Uber drivers tend to be less pleasant and their pricing less transparent than other services.

With all the income tax, property tax, VAT (21%) and ridiculous gas prices (about $6.60 per gallon) life isn't exactly cheap here.

Our middle class has been demolished by the Satanic trinity: housing, healthcare, and education costs.

Tuition: our reputable public universities are comparable to European private ones in cost. Our private ones cost almost $50k per year. It's also competitive enough to get into the top universities that the game increasingly starts in high school or before; in New York, it's very typical for merely middle-class parents to hawk up $30k per kid per year from ages 4 to 18: admissions are that competitive.

Health insurance is another nightmare. Decent plans cost $500 per month for an individual in a employer-provided plan (and, increasingly, "employee contribution" of 25-100% is the norm). If you're on the individual market, you're fucked: it's closer to $1500 per month if you're healthy and have no children.

Then there is housing. You can actually get a good deal (say, $150 per ft^2) in wide swathes of the country-- but those are in places with imploded job markets. To buy anywhere with an active job market is pretty much unaffordable on the typical software engineer salary, and even rents will typically be 20 to 40% of after-tax income.

Europe has a lot of issues and extended liabilities, but the U.S. is far more fucked in the coming decade. I'd gladly pay $7/gallon for gas not to have to worry about healthcare (even if you have insurance, it will often fail you at the worst time) or, in the future should I have kids, education costs.
