If I were to hire someone, and he claimed he can put in 12-16 hour days for weeks on end, I'd be inclined not to hire, based on the expectation that it means that he's either bullshitting me, or does not understand his own limits.

In 17 years of managing many dozen staff, mostly developers admittedly, in a variety of different settings, I've never seen a someone that managed to be productive with mentally strenuous even a full 8 hour day at a time other than very occasionally when they're on a roll. Generally, the ones that do best are those who manage to spread out their work, take proper breaks and intersperse the rest of their mentally demanding work with "menial" tasks, and who goes home and puts their work away completely.

Maybe your're an exception, but if you are, be prepared that people will either disbelieve you or expect you to prove it. More likely, your idea of "sustained 12-16 hour days" only actually involves a few hours of what the rest of us would consider mentally strenuous work a day.

Put in 12-16 hour days for a while with repetitive, simple tasks taking most of the time when working on something that is overall exciting, sure, that works for a while (though eventually that too tends to produce burnout - I've had to order developers home after the strain starter producing negative results with fewer hours than that).

For me, what works best is that whenever I feel that my concentration is slipping, if I don't feel I have time for a proper break, I will switch to mindless tasks, such as updating my todo list (often spending time breaking bigger tasks into tasks that are realistically small enough for windows of a couple of hours), doing my e-mail, or if I'm home I'll do the housework, and I'll try to "switch off" while I do, practicing mindfulness meditation for the truly "mindless" tasks such as cleaning.

Sometimes I get lucky, and my concentration stays on top for longer in one go, and I cherish those moments, but I "pay" afterwards (e.g. crash on the sofa when I get home, or need to slow down the following day).
Thanks for the great answer :)

Their first statement "there is little mathematical value to finding a single new prime" is very true, but in the second half of the article someone demonstrates his 'competence'...

"This is a tablet"

It beggars belief that Microsoft could consider this competitive as a tablet. As a laptop, the power and price point makes sense. But as a tablet it's thick, heavy, has very poor battery life and 99% of meaningful Windows software wasn't optimised for touch.

I was actually considering purchasing one of these. But watching reviewers attempt to use this thing as a tablet depresses me.

I'm probably dreaming, but I would love to see Microsoft just make a really nice touch screen laptop with the same design aesthetic as the Surface.

I think I didn't make myself clear:

- You say However, since it could be very useful for users of a database to store ordered data, or to wilfully concentrate certain data on certain parts of the cluster, god does not force the user to hash the keys. -> why do you care about how the data is actually stored?
- To map keys to values, a mapping structure is needed. For infrastructural reasons (synchronization and cleaning) as well as for functionality of different kinds, we need a sorted mapping, and it has to be deterministically structured. -> why?

Pricing is a big topic. It's time for my obligatory remark about how those of us who sell software or services should give it more attention.

Consider these questions:

Node or Rails?
JavaScript or CoffeeScript?
LESS or Compass?
Foundation or Bootstrap?
PaaS or self-hosted?

What do all these questions have in common?

That, compared to your pricing strategy, they are pretty close to irrelevant as predictors of your profitability.

Nice work. I spent much time last year building a system that imported MongoDB data into Oracle, having to do everything to speed up bulk loading new data into Oracle (and archiving old data). Something like this would have worked much better, and I suspect it might not be that hard to make this tool work with Oracle.
I'm a huge fan of Wikipedia's Simple English wiki, and its page on prime numbers gives a great example of why:

http://simple.wikipedia.org/wiki/Prime_number

Without having to wade through pages and pages of information, you very quickly gain an understanding of the basics.

A 30-second skim of this page - which includes "Prime numbers are very important in mathematics and computer science." - would've prevented this reporter making such an obvious mistake.

This is a REALLY bad headline. That pull quote does not exist ANYWHERE in the article.

As much as I dislike Fox "news", this headline feels like complete BS.

Second, a way to handle fiat money, Bitcoinica famously sidestepped that because they were not a true exchange, and were more of a sort of "betting" platform.

Some exchanges negotiate with banks, to do their thing.

Third, making a software that is not buggy enough to be exploited.

I know of a exchange where it was possible to withdraw USD twice (you deposit say, 1000 USD, then withdraw 1000 USD, and 1000 USD again).

Another one, calculated your fees only after you requested a withdraw (so, suppose you wanted to transfer 1000 BTC, and the fee for withdraw was 1%, it would allow you to transfer 1000 BTC, keep the BTC, and then would set your account to -10 BTC)

Or Bitcoinica once that had negative spreads, thus just buying and selling like crazy had outrageous profits (and outrageous losses to bitcoinica).

I think TheVerge's conclusion [1] says exactly what I thought about Windows 8 and Windows 8 hybrids from day one:

"It tries to do everything, but misses doing anything really well"

Something like the Surface Pro has a lot of compromises, starting from the schizophrenic UI, to high price, too small screen to be productive on it, low battery on it, heat, noise, fans, and so on. It's not the "best of both worlds". It's the worst of both worlds.

The fact that people talk about the "market capitalization" of bitcoins suggests that they treat it as a speculative investment and not a currency.

> why do you care about how the data is actually stored?

I just said I don't. 'god does not force the user to hash the keys'.

> > To map keys to values, a mapping structure is needed. For infrastructural reasons (synchronization and cleaning) as well as for functionality of different kinds, we need a sorted mapping, and it has to be deterministically structured.

> why?

Functionality: To be able to return the first or the n'th entry it has to be ordered.

Synchronization/cleaning: To be able to hash element 0000-000f we need an efficient way to fetch a segment of elements, thus it again has to be ordered.

To optimize the hashing so that I don't have to keep two separate data structures I keep the hashes in the nodes of the sorted data structure. Thus the structure has to be deterministically structured or the hashes won't be equal even if the trees contain the same data.

- can only set logging level in the config. and, xml logger config doesn't have application.conf values (logger.* in .conf are useless)

- routes dsl (meh)

- bad db connection pool. it kills all other connections if a connection fails, and goes into error state instead of re-connecting (it does reconnect for subsequent requests when pool is in error state)
It is interesting the focus on academic achievements.

Yet I think, that yes, it means they might be hardworking people, but does not guarantee much else.

Sometimes you find great people that are not even graduated, and I am not talking about "Bill Gates fake dropout", but people that never set a foot in college in first place.

Some people started their trade very early, sometimes in childhood, and when they reach 20, they are already masters of it.

Of course, these are rare, so if you want to risk less, hiring only the best of their classes is fine.

I think it's problematic that the package list on the chocolatey website doesn't show the version numbers of the apps. If I install that Python package, would it be 2.7.3, 3.2, or another one? Ninite does this well on their website.
Setting up the system once is only half the problem. Most power users have a whole host of links of tools that they will usually need and install on a new machine, but things get really ugly when your stuff gets out of date and the applications don't update themselves. IMO this is the much harder problem that is solved by package-managers. The Windows Way requires each application to replicate some auto-update process which is a great recipe for disaster.

I don't get it - Why do people abuse the term 'hacker' so much? If it's so much hip being one, then, why not try to be a real hacker instead?? Why do people simply call themselves a 'growth hacker' when all they do is simply send a bunch of marketing emails to Techcrunches and Mashables and some PR agencies??

Similarly, it was the term entrepreneur before, for example, I have a huge list of dudes on my Facebook with titles like CEO, CTO for a <insert a dotcom domain with a wordpress blog with a free theme installed here>. Being an entrepreneur/hacker is one thing and abusing the terms is totally another!

Very interesting article. I think it can even be extended to other kinds of software.
I've faced this question on the App Store, which is, of course, a totally different market My experience is that pricing an in-app purchase at 0.99$ or 1.99$ does not change anything as long as it brings a significant added value to the app.
It clearly is important not to lower our prices too much. I think the TV industry (Panasonic, Sony...) should be a reminder that we can not indefinitely lower prices.

>I don't think it started out that way; in fact I know it didn't. But over time we went from "watercooler for hackers" to "stuff that interests hackers" to "stuff that interests hacker wannabes" to something-else, not sure what to call it. Maybe "stuff that hacker wannabes like and most techies are interested in"

Can you put some more arguments behind that? Like: HN is having more/less articles about XYZ, therefore it's less interesting for real hackers.

Also I am curious what your definition of hacker is. I have the impression that what you really mean is 'But over time we went from "watercooler for tech entrepreneurs" to "stuff that interests tech entrepreneurs" to "stuff that interests wannabe entrepreneurs" to something-else...'

I was just looking at some screenshot of HN in 2008 and I have problems to see a great difference.

Wind is already cheaper than nuclear would be in Denmark (using prices from the UK). Solar is getting cheaper too. Whether they're viable or not depends on location, e.g. solar isn't really too great in Denmark, we're too far north. Storage is a problem, but not quite as big as you would think, and a multitude of solutions do exist.

Denmark has a plan of getting rid of fossils over the next decades, and we're well on our way. It's not a research plan, it's an investment/building plan.

Furthermore, while some subsidies are currently needed to cover risks and capital expenditures, the studies I've seen predict that we're probably going to end up with an infrastructure that's not more expensive, it may even be cheaper. Like energy from an old nuclear power plant is really cheap today because the capital expenditures have been covered many years ago (discounting insurance and other thorny nuclear issues).

I participated in a Hackathon this past weekend where the organizers had formed a panel of technology experts to interface with the charitable organizations that we were hacking for.

This was really excellent, because they met with 12 different charities many times over a period of time. By meeting so many times, the tech panel was able to tease out some really specific ideas and the hackathon ended up being pretty great.

It was my first hackathon and I learned a lot about what not to do. C'est la vie.
My biggest concern with reducing prices is that it in turn pushes retailers to find a way to reduce the quality of the products they are offering (they don't want to operate at a loss and when they can't achieve the massive scale they need to justify the price cuts they need to do something about it).

The short term effect may seem that the customer is getting a good bargain but in the long term it can only hurt him.

To give a better context (software related), I often look at the price estimates certain software development shops are giving in Elance/Odesk/Freelancer.com to potential customers and their very low pricing can only make me wonder if they'll be able to deliver a quality product.

You should raise your prices in order to give a better product and a better service.
