There's a reason prices are always hidden in jewelry store display windows. There's a little price tag on each item, but it's always tucked out of sight.

IMHO, there's pro's/con's to publicly listed pricing. There's definitely no hard and fast rule. Some con's to consider:
[1] It anchors prospects at certain price points (can be good and bad), [2] It might scare people off before you can value sell them and justify your pricing.

With enterprise SaaS, it entirely depends on: [1] what you're selling, [2] who you're selling to, and [3] the buyers' journey you're looking to accommodate / create.

I vote for this being a scam. A very clever scam but another scam.

There is in fact whole cottage industry centered around energy and battery technology. The audience for this is not us or other scientists but investors. It is about demos, videos, secrets, lots of tubes and wires, flickering lights, acting like they just discovered free energy and will revolutionize the world of physics. The goal is to make people with money believe you.

In general, just because people have money doesn't mean they also know science and thus many are targets of scam artists. But the "art" part in scam art is to also pick an area that is not too confusing (brain surgery, genetics, something too theoretical, etc) or too hard but something seemingly simple -- "we make energy", "we have a new battery", "a device that produces more energy than it consumes" etc.

You ask a question that was already answered: inequality is entrenched in society. Yes, it has obviously gone way up during and since the transition from traditional communism, when almost everyone was pretty much equally Mao-suit + rice + red-book poor.
But that type of network effect is easily undermined by a service that offers cheaper fares. I saw this happen first-hand in India where Ola cabs, which was being used by almost everyone, quickly started losing users to Uber once Uber started their massive discounts and promotion series in India.
otherwise, it seems overkill to need some public API to do this.

One option if you have suitable waves would be to produce a hinged raft and have the flexing motion of the raft produce electricity via hydraulic motors like some wave power systems.

I need to find regular work, and justify the CS and graphic design degrees I now have to pay off.

I'm currently working on rebuilding my personal site, hosting my portfolio (currently split between Behance.net and Linkedin) and resume, dusting off various aborted projects and hosting them on my site as resume filler, and trying my best to make a four year gap in employment while I was going to school and only taking short-term and freelance projects not look radioactive.

I'm not planning on learning any new tech, but I need to brush up on my art and writing skills, and actually finish a game project that isn't terrible, so i'm planning on doing the 1 game a month challenge just to prod myself. I might wind up trying and giving up on Clojure again.
> But testing ensures no such thing

Yes it does. Empirically.

>considering that comprehensive testing across the entire space of possible inputs for a unit is infeasible in most cases

Fortunately, it is also not necessary, as numerous studies have found.

>I think static typing and testing are much more complementary than you're giving them credit for.

I totally agree that they are complementary. I find static typing to be most useful as checked documentation (for which, unlike the safety aspects, there is actual empirical evidence). Also, it makes various optimizations easy/cheap/predictable, which I find highly valuable.

Finally, it does help a little bit with correctness, though far less than what many people claim.

However, it also has costs that are not insignificant, in slowing down exploratory programming, compile-time costs, brittleness of designs and often code expansion / productivity.

More importantly, it appears to harm compositionality/reuse, at least at our current level of understanding. Both Unix Pipes and Filters and the Web, arguably the most successful reuse mechanisms in the history of software, are dynamically and somewhat loosely typed. In addition, personal computing was invented in around 20KLOC using Smalltalk, a dynamically typed OO language.

> No, you've created software that works the same now, but could cause a fork.

Where is the problem? As far as I understand it (but prove me wrong!) in the extreme case we'll have two Bitcoin blockchains: One without the block size restriction and one with. In each of these two blockchains there will be a consensus (that's what the Bitcoin protocol is in principle about). In the "typical" case the supporters of one of these two forks will stop mining in it, since they see that it is "not mainstream enough". If both blockchains have lots of supporters behind, we'll have "two different bitcoins". Here it can get interesting, since now we have "two different products/bitcoins", where the market will have to decide (and in the extreme case this ability to choose will damage bitcoin - here also things get interesting).
cuDNN is just a library written by Nvidia for Nvidia GPUs. AMD maintains a OpenCL version of Caffe (another popular framework for DNN), and apparently other DNN frameworks also have or will have OpenCL support.

Yap. This is almost certainly a scam. As long as there are rich people, there will be scam artists selling them "cold fusion", "infinite energy machines", it is fascinating to watch these happen.

This also creates an interesting market, just like scam artists look for marks that other scammers have deceived, there is probably someone taking notes which investors are buying into the story. Those people would be good targets for the future.

Wow have times changed. I lived in a (much less nice) communal building in Bushwick, Brooklyn a few years ago and it was just $500 a month for a room. As a newbie to NYC at the time, it was really great to jump into a fully formed community but after a while, it was just too much to be surrounded by people all the time. You could tell others were having the same issues and people started to pick fights over silly things and it just became a very stressful experience. This place is significantly nicer than where I stayed but I wonder how the issues that come with putting a large group of diverse people together in one space will be handled.

Today, yes. Today recording means we're still taking a camera and do some actions.

But love it or hate it, but it seems that we're grasping wearable computing. And that includes stuff like hearing, vision, memory or navigational aids, and such things depend on recording what's going on around the wearer. So, while today there's a clear distinction we're just bound to hit the issue some years in the future. And given that some tech is already there, said future doesn't seem to be too far away. Then the difference would be much smaller. Probably even non-existent if we'd get anywhere close to what transhumanistic sci-fi pictures ;)

Here's a plan B based on several experiences with enterprise SaaS:

Start with something that isn't awful. Get it up early. A/B test that crap out of out.

Keep it simple -- Only have one unit of measure (UoM) or feature differentiator at first. Having multiple points of differentiation or UoM leads to confounded experimentation. Try to add more " per's " over time :)

You can take forever debating this stuff. Data is the only guide.

I hear you. I develop on Linux natively so the Docker experience is quite good for most things but there's still issues even outside of OSX.

For example, let's say you're using PyCharm or RubyMine and your code lives in a container. Currently there's no sane way to get code-complete or run a debugger on the code that resides in a container.

I'm looking forward to the day when all of that is ironed out.
Ask HN: Open Source my web app or Sell it on Flippa?

according to wikipedia Pons and Fleischmann self-funded the experiments for several years before the announcement to the tune of $100K.

Anyway, giving such a great palladium's absorption of hydrogen it would be interesting to see a grain of palladium deuteride as a target for NIF and/or Sandia Z. The density of the deuterium absorbed into palladium is about the density of the standard frozen DT grain used traditionally, yet with all these additional heavy palladium atoms spread around the stability of compression would definitely be different - whether better or worse the experiment would show. Also the electrons would be in typical in-metal cloud state instead of being attached to the deuterium atoms - again the difference which may play a role (at least in lithium deuteride used in H-bomb it doesn't make things worse :)
sigh.

Tech workers make up ~8% of SF's population.

Programmers are low-paid highly-paid workers. (Especially when you factor in rents in SF.)

If tech workers didn't move in, it would be folks in biotech, or finance, or high-end sales, or...

There are many factors that drive up rents in SF. The primary -and by far largest- factor is the fact that it's nearly impossible to build new housing. Get the City Supervisors to hang obstructionist landlords, NIMBYs, and Real Estate Investment Firms who are currently making mad bank [0] out to dry and you'll -relatively- quickly see rents drop back to vaguely sane levels.

The enemy isn't tech workers. The enemy is those who choose to make obscene profits, rather than permitting others to build housing to meet current and near-future demand.

interesting idea - and very much in the spirit of the project.

It's a pretty closed off harbour so there aren't really any waves, and there's almost no tide so not much flow past the raft either. Especially since it's moored in a sidechannel. So it probably won't work :-(

Kudos for the idea though.

Page 8 of this NASA document is the most trustworthy single page source I've found so far:

This chart gives (among other things) fatalities per passenger mile for 2005-2012 as a multiplier of the per passenger risk of death when traveling by automobile.

Passenger auto: 1x
Commercial Airline: .006x
Motorcycle: 40.2x
General Aviation: 12.0x

This would suggest that if all else is equal, and you are scheduling a trip from point A to point B, your chances of dying are about 1000x worse if you travel by private plane than by commercial airline, about 10x worse if you travel by private plane rather than driving, and that it would be about 4x safer to take a private plane rather than riding a motorcycle to your destination.

Of course, all else is not necessarily equal. A daytime motorcycle ride in full gear in good weather is definitely safer than an unexpected night flight in the fog with a low hour private pilot. A trip on a well-maintained corporate jet with an experienced pilot is almost certainly safer than snowy roads in a rear-wheel drive automatic. And of course, statistics don't answer the question of what should and should not be acceptable risks.

OpenAddresses is a directory of publicly available address lists provided by government agencies at various levels. It's designed to be bulk imported by machine.

Many addresses exist in OSM. But there's a preference from the OSM community that data be entered by users familiar with their areas, that they can verify on the ground. Imports have happened in OSM, such as the controversial TIGER import in the US years ago, and the NYC building dataset more recently. But these require a lot of effort and attention to manage well.
> foo(); bar();

The whole point of composition is that foo(bar()) is foo(x) where x = bar(), which means that you can understand the combined program by understanding foo and bar independently. If you can't represent the result of bar() as a value x then that breaks down, in which case I don't see what this whole project is about? I mean being able to implicitly pass down a handler is cool, and there's some value in being able to swap out e.g. a "real" and "test" version, but it sounds like the effect sequencing is still directly coupled to the code operation.

> With monads you need to make sure that they both return the same nesting of Log[Writer] or Writer[Log], but I don't need to care.

You only don't need to care if the effects commute - and in that case you can actually automatically move them past each other in the monad world (my scalaz-transfigure library does this, at least at the proof-of-concept level). For noncommutative effects you can do the same thing if you're willing to fix the nesting order (e.g. say that an exception always trumps a later log, or always doesn't).
