Solar storage economics
Expansion of space allows for the distance of two objects to increase such that it appears that one is moving away from the other at a speed greater than c/2. I think it is possible for this to even be greater than c because it is the expansion of space and not objects movement contributing to the increase in distance.
I am leaning towards this view. Advertising has existed since pretty much the advent of writing and commerce but technological advances have made it increasingly sinister. Through targeting, automated split testing and other advanced methods the advertising industry seems to exist to weaponize psychological research.
> But stars are getting fainter and fainter as they are further and further away. I get that there would be an infinite amount of them, but then it's an infinite times a zero.

No, it never goes to zero, it just gets fainter. An infinite number of small numbers adds up to infinity.

> since the sky is indeed black, then it has to be that it's because the dimness of stars prevails over their number and/or density.

As the article mentions, the sky is black because we cannot see infinity. We can only see the observable universe.
I have such high hopes for pervasive solar power to drive new markets. Fossil fuels are an increasingly ugly hole - they're becoming increasingly expensive and destructive to extract, and resource wars over energy extraction sites and transportation routes will become more and more violent and contentious.

Cheap clean power plus 3D printing allows for unique new markets to happen.
What I was getting at is the need to actually look at those costs rather than just assuming that it's always better to maximize flexibility. Running your own services has a high up front cost because you have to pay people to build, test, and secure everything before you see any return. You can come up with estimates for the various outcomes and how likely each would be but that's a lot more nuanced than this thread had been, particularly with speculation like “What if they suddenly increase the price by an order of magnitude?”.

The detail which I think techies are particularly prone to forget is that businesses deal with “lock-in” (i.e. contracts) all the time; it has downsides but managing those is routine. In particular, many businesses love to defer up-front costs into a structure where they only need to pay for actual usage.
Perhaps "complexity" should be used instead of "great engineering". The best engineered solutions are those that are simple, easy to understand, and fulfill business needs (profit, time to market, etc) vis-a-vis satisfying the programmer ego (In saying this, I'm pointing the finger back at myself as one who really loves to over-engineer)
The phone one was a bit grating because the numbers didn't have any quantities attached to them. Though of course that would make the question trivial, if I wrote something like "P = 108 - 23*d", I'd get marks off and a big (WHAT?) next to the numbers. Without specifying 108 whats it is, it could be 108 peppers or 108 bicycle-riding monkeys wearing suits. It's more of a common sense question than an actual mathematics question.
Tim Berners-Lee: https everywhere considered harmful
Webmail struggles to offer security reassurances when utilising public key encryption. For example if Google allowed you to upload your private key and email would be transparently decrypted, that would be a great user experience, but now you have no way of knowing if the NSA/GCHQ/etc forced Google to give them your private key.

If you didn't upload your private key to Google now you need your browser to decrypt your message in-line but preventing the website with the encrypted version from stealing the resulting decrypted version from the secure container. So that requires every browser to add these secure containers, for content to be marked for decryption, and for key storage.

If you aren't worried about usability then you could just write a Word document, encrypt it and attach it to an unencrypted email. No browser support, or website support needed.
Since cost of living and rent varies widely by location, it'd be much nicer if I could set multiple expectations of salary. You'd have to pay me more for me to be willing to move to SF, for example, but I know I can expect less if I'm working on the east coast, or say, Tokyo, where programmers aren't as 'hot'.
StackOverflow does not have to pay editors, they have users that contribute for free. Somewhat tacky of SO to not mention this fact.

Just like traditional writers have publishing statistics, online writers use analytics to calculate how much reach their pieces have. It is sad, but writers count on pageviews, which is why you see many clickbait titles.

I agree. I've always thought that "preparation" for the vocabulary and critical reading for the SATs starts in early high school or in middle school. Sitting down and memorizing ~200 new words that you hope will be on the exam isn't as helpful or effective as simply growing up in a home where college educated parents use "SAT" words in daily conversation. I say "simply" because the children who do have that advantage gain it merely by absorbing what's around them, in comparison to other children who don't have that advantage.
The red shift applies to distant stars too. The important point is that even in the extreme scenario where all stars last forever and you wait an infinite amount of time for light to reach you, you will still never see a fully illuminated sky because the stars are receding much faster than the light propagates due to metric expansion. Saying the sky is dark because 1) the Universe is young or 2) stars are short-lived is just false. The Universe gets darker and darker as it expands, despite there being "more time for light to reach us".
This is an important concept to understand: https://en.wikipedia.org/wiki/Comoving_distance
No, its correct.

I lost a youtube video that explains Universe. Basically a universe observer is like an ant sitting on a big balloon that is constantly being pump with air. So while the balloon age might be 12 billion years old, the speed the air is pumped in it makes it grow and therefore objects "placed" far further than originally; hence 46B for an observer.
The spending on pure research is trivial compared with IBM's profits. In its last financial year: "Total capital return to shareholders of $9.5 billion; dividends of $4.9 billion and gross share repurchases of $4.6 billion"

I know what you mean. Sometimes, though, nonconformity can be done for practical reasons. It's not always about being different for the sake of challenging the status quo.

My landlady ran into a problem with her Windows 8 machine. To fix it required sending it to a PC repair shop and spending the 80 bucks for them to look at it and get it back in working order. She ended up being without her machine for a few days.

Then there's me. When Windows Update bricked my Windows 8 machine, I checked my options (and my bank balance). Couldn't afford the PC tech. So I grabbed a Linux Mint DVD I had handy, salvaged the files I wanted to keep, and replaced the operating system. I was without my machine for less than 24 hours.

Sometimes, the "nonconformist" choice IS the path of least resistance.
If you base the rule on net income instead of gross income, you'd need 200k per year to afford it properly.

Assumption: 40% is the federal + NY state + NY city income tax for a six-figure earner

200K * 0.60 = 120k of net income = 10k/month net income

3k rent / 10k monthly net income = 30% of net income
Well said, I interview a lot of developers and always refuse to add to our interview process or ask any questions where the candidate could easily google the answer.

We will do a basic phone interview, to seek out what they know about the areas we work in and then dig - explain how it works and why how we would use it?

Then its a technical test if they pass the phone interview. Now demonstrate some the concepts we previously talked about.
The dream of owning a house is out of the reach of many people under 40 in the UK: especially in large cities and towns it's common to share houses. It's not completely uncommon for people over 40 to be sharing.

I'm paying €650 for an en-suite room (no, not London!) and that includes all bills, sharing with 4 others. I'm one hour from London by train (~40 miles/65km)

Most one-bedroom flats in this area start at €975/mo, plus you need to pay €140/mo council tax and €100-150/mo bills (gas, water, electricity, Internet etc). Many couples rent for a long time before saving enough for a deposit to buy a flat/house.

It's terrible. House prices seem to rise by the amount of deposit you can save in a year...
I was also surprised by the 20%, as I thought I had read that it was approaching 40% across the web (thanks to YouTube, really). I wonder if this means a significant share of Wired readers had already whitelisted the site.

I'll take one point here. Antirez's point that clients have to timeout on locks, otherwise the resource will be deadlocked is not correct.
We implemented an alternative model based on distributed shared memory. Clients take a lock on the root of a subtree (of potentially millions of inodes in our version of HDFS) and persist the lock to shared memory and look for existing locks on the subtree in shared memory. If the client dies while processing the subtree, its lock is still persisted in shared memory alongs with the clientID. If another client tries to take the lock and it notices the client holding the lock has died, it takes the lock.
We used heartbeats to shared memroy to implement the failure detector for clients (based again on shared memory http://www.jimdowling.info/sites/default/files/leader_electi... ). Importantly, timeouts for heartbeats expand when the system is congested.

I think the dirty not-so-secret of advertising is that for most content on the web the ads are awful, poorly targeted (or at best basic retargeted). Many content producers want to focus on building great content, so advertisers go for low CPMs and spray and pray. This is why the brands are so interested in Facebook and other platforms that seem to be able to deliver great content and are, increasingly, willing to pay the differential.

It's impressive to see StackOverflow putting this together in-house and I imagine it'll continue to be a competitive differentiator for companies that can pull it off going forward.
We've been taught by the "old generation of programmers".

Think about it.
Which is pretty plausible, right? (Becoming co-dominant with google).

The other thing to consider is the competitive/strategic landscape. It's not so much that the market 'assumes' that Facebook will invent new ways of making money, but rather that regardless of who figures it out, facebook is so incredibly well positioned at the moment (ubiquitous social network) as to give it a large competitive advantage, and let it eat other companies' lunch.

The market has examples of other similarly well-positioned companies, like Microsoft in the early 90s, to draw on.

It's still not ready for production use. One problem with e2e is that it's JavaScript based and runs in he browser, so there is a certain attack vector present there. To defend against this, ideally e2e needs to work with a smartcard (such as the yubikey neo) so that the private key cannot be stolen.

There was an issue I was tracking a while back to integrate this support, but it's still a work in progress.
For what it's worth I've always heard it as 30% of your gross pay, not net.
This is what GMail is doing: making sure that sending an email is like sending a letter (instead of a postcard). TLS email is not 100% secure (private, authenticated, etc), but not 100% insecure either.

Verifying TLS for email is an easy step in making email a bit less insecure, and it requires no intervention from users. If you need something secure, then yes, go for GnuPG or other forms of end-to-end encryption (if only I could name a few).

I don't have a problem with ads, I mostly object to tracking, profile building, and the sharing of that profile. When I read a People magazine in my doctor's waiting room, nobody knows much about me in particular. There are online ad networks that serve dumb ads and those I generally whitelist.
Distributed time is tricky, but it depends on what the intended use is. Under normal operation it will only move forward, for example.

System clock will take a larger step than usual. It won't go backwards.

None. System clock is UTC for a reason.

NTP only drifts the clock (under normal operation).
I opened this link, thought the site looked interesting. Scrolled down, saw "Yahoo," "Microsoft," and a bunch of companies I've never heard of.

Interest went from 70% to 0. Yahoo is not "Top Tech," it is a corpse of a company that has recently layed off tons of staff, has dim prospects, and has recently been accused of sexism. And the fact that you call it "Top Tech," demonstrates to me that the site lacks integrity.
Have definitely thought through this process and wound up using Redlock for the time being.

I didn't expect it to be a perfect system but I don't want to deal with setting up a queuing system right now when there simply isn't enough activity taking place.

Will it fail at some point? Possibly, but it's a great intermediary solution as you state. I for one would be curious to see other solutions to this problem. Are there any resources you'd recommend?
This is absolutely true. Stephen King said that if you want to be a writer then write a lot. 2,000 words a day.

When I was in 6th grade, I used to shoot free throws every night for hours. Just for fun. We had a track and field day at the end of the year and I beat out two guys for first place in the free throw competition who went on to play basketball on our high school team.

I beat them at something that they cared about a great deal and I didn't care about at all, simply by inadvertently practicing a lot.

Fair enough but do you think a 1-2 man shop can get better reliability than a product like Parse if they are average app developers that don't have Ops experience?

EDIT Since I'm rate limited:

> I don't think any product exists that's going to remove the need for ops experience. I haven't used Parse, so I can't comment on its reliability.

If you are an app developer whose backend consists entirely of talking to an API, I'm uncertain exactly what "ops experience" on the server side you believe is needed?

Yes, it's still incorrect! The complete quote is:

> Astronomers have concluded that the universe began some 12 to 15 billion years ago. That means we can only see the part of it that lies within 12 to 15 billion light-years from us. There may be an infinite number of stars beyond that cosmic horizon but we can’t see them because their light has not yet arrived. And the observable part of the universe contains too few stars to fill up the sky with light.

(Emphasis mine because that's where the error is: 13 billion year-old light has traveled over a distance that is now much higher than than 13 billion light-years)

Potential ambiguity (in cases such as this one) is one of the reasons why using light-years for distances may not be a good idea.

(By the way, there are real astronomers arguing about this, too, e.g. http://www.astro.ucla.edu/~wright/Dltt_is_Dumb.html . So it's not just this nerd ranting on HN).

GRB 090423 (admittedly, not a star -- it's a gamma ray burst) happened approximately 13 billion years ago. This means that light traveled for 13 billion years to reach us -- but, by the time it got to us, GRB 090423 was no longer 13 billion light-years from us, because all that space got bigger! GRB 090423 "was" about 9.2 Gpc away from us by the time that light reached us, i.e. about 30 billion light-years.

If the light that hits us is 13 billion years old, that object (assuming it still exists) is a lot farther than 13 billion light-years from us now.

Technically these micro-apartments are the solution, even with their seemingly outrageous prices.

This assumes a minimum energy from each photon. If you could red-shift indefinitely you could end up with ex: 1 + 1/2 + 1/4 + 1/8 +... which sums to 2.

I believe the minimum energy of a photon is directly bound by the age of the universe, so if the universe was twice as old you could have photons at 1/2 the energy. You do get more light sources as you increase distance, but the inverse square law balances that. So Sum (1/n) from 1 to N which really slowly grows to infinity. As in 10^100 = 230.84
We relied on Parse to send push notifications and since the announcement were looking for alternatives. We decided to go with pubnub (which FWIF we were already using for other stuff). I think it's worth for anyone who was using parse to check it out.

> Ronald Regan, as a movie star, regularly didn't make movies precisely because the progressive tax system would head into confiscatory levels making the effort worthless to him.

Really, if the greatest cost to society you can point to of increasing the top marginal income tax rates is "fewer Ronald Reagan movies", I don't think you are making a very strong case.

> Such rates denied both the public at large from products they wanted, and the government tax revenue.

The case that it denied government net tax revenue requires more than Reagan not making movies, it requires a whole-economy comparison of what activity occurred instead and the actual taxes applied against that activity.

> I want to encourage people to make insane amounts of money, because that is largely the result of far-and-above productivity which everyone else benefits from.

This "trickle down" concept is a widely held article of faith in some parts of the population, but not a position well supported by evidence.

> The cost of discouraging effort is never included in these "soak the rich, redistribute the wealth" equations.

The "cost of discouraging effort" is very hard to empirically establish without ambiguity, and there are sharply different opinions on what it actually is. What proponents think that cost is usually accounted for in where the various parameters are set; people who have different views of what the cost is, obviously, disagree that these settings are correct.
Hey guys,

We've built an app to help freelancers find more gigs easily and avoid competition that is overwhelming on Upwork, Odesk, etc.

We've just released our MVP and we are looking for some early testers of the idea in general and improvements we need to make. And if you break stuff -- it's even better!

How it works: we look for critical business events a company might have in several industries and filter the noise out. We started with twitter as it's the easiest one to test and will add other channel like angel list and crunchbase later on.

Thank you,
Sasha.

I don't think you should limit this to the "new generation." I am at around 5 years experience in the dev workforce and believe I can answer those questions to a satisfactory degree. From interviewing and professional experience these are questions that seem to give everyone trouble. I interviewed a guy with 15-20 years of experience and he didn't understand B-Trees and indexing but his mentality was: why should I bother? that is the DBAs territory.

Obviously, my background is different. I think this is the root of your issue. Most people are learning what they need in order to get a job completed. Most of the time it doesn't involve them having to build the entire application, they are asked to work on a small portion.

All things considered, I agree that devs should understand more in depth the core components of web applications.
