It is perfectly within our reach to simulate a bright daylight sky with the sun behind clouds - around 5k-10k lux - it just requires a fairly large wattage of lighting in a number of indirect fixtures. White metal halide, LEDs, and fluorescents all have efficiencies in the 50-100lumen/watt range, that just means you need to apply around 100 watts per square meter of matte white ceiling you're trying to illuminate. I like the idea of supplementing the white lighting with colored (eg: red, red-orange, green) LEDs, which can be throttled to achieve a particular color temperature.

Ideally your ceiling would be very high for this setup to give space for the light to diffuse from hanging ceiling reflectors, which is unfortunately not the case for most homes. For realistic homes, there is a style of floor lamp termed 'torchiere' that may work, though for best results you're going to want to find one with a large, fully reflective shroud - lights this bright are pretty harsh if they're not diffused well.

Set up something like this on an automatic timer to simulate the sky, and I suspect a lot of our sleep issues would go away fairly quickly.

I'm curious about the choice of bmp for http://wdobbie.com/warandpeace/glyphs.bmp

Why not a png ?

Edit: So after a quick test:

* glyphs.bmp 53.5 MB

* glyphs.png 7.6 MB

I guess it could be shrinked even more.
For those who are interested, the human connectome project is in the process of acquiring and publicly releasing a database of 1000+ MRIs collected from normal subjects:

http://www.humanconnectome.org/data/
Smallest commercially viable SQL database is probably the latest k5/kdb (http://kparc.com/), which is implemented in something like 9KB of code (source: http://kparc.com/o.htm).
For a book published in late 2014, it's very strange that this book doesn't seem to mention any of the state of the art components in neural networks, including:

- Convolutional neural networks
- LSTMs
- GRUs
- Autoencoders
- Attentional mechanisms
- Variations on SGD (Adagrad, Adadelta, RMSProp, ADAM)
A quick Google confirms this: they use either an identical-looking light with a different response, or a different light altogether. "Here's a light, here's a sugar pill, log your mood please..."

As silly as that all sounds, it's already a million times better than what this guy did. He took the "if a little is ineffective a LOT will be better" approach and built a damn lighthouse in his living room. And if the goal is a DIY project and a blog post, OF COURSE you'll feel better after "your treatment." It's approaching group therapy at that point. There's a lot of this crap on HN lately.

Hi again,

To answer your other questions, I have no real plans to monetise this. I did try to raise funding for an 'art/culture travel app' that underpinned Codex but the focus was too niche and I didn't have a graphic designer. I think an open community driven project would be more useful, overall.

Regarding Neo4j itself, most of my queries are run across the node paths rather than text so searches as such. So I haven't had to deal much with internationalisation issues (e.g., and searching for text with or without acutes, graves, etc.) The data in the system is pure Neo4j and not sourced from SQL of any kind. ;-)
But you have to first pay for there basic service, and then their catalog is very restricted. The attraction of Netflix + VPN are the very significant catalog, and the price. I'm ready to pay a bit more, but basic cable fee + rental fee is not reasonable. Also, I do not want to sponsorise the garbage on basic cable.
Sure they are, but don't they opt for the "nice car", "younger girlfriend", etc?

I don't see many 45yo people wearing 20yo clothing -- there are some of course, but not that many to be a "phenomenon" one would notice.
I would like to see a study that compare the commercial incentive vs the deincentives cause by the chilling effects from patents. It should be a standard cost-benefit analyzes with no emotional/political bias that could give a final scientific answer if patents are beneficial for software or not.

I'm definitely outgoing- I have no problem making myself the butt of a joke to get the laugh, but at the same time I'm not so outgoing that I'm one of those guys who could go on a trip by himself and make five new best friends. Nor would I just go to an event and meet like 10 people and go to dinner with them that night.

I'd consider myself normal outgoing and I think, at least in a work environment, it is my self confidence that alows this. I know my input won't always be right, but it will be way more often than not- even then it will probably still have value. So I throw out my ideas in meetings where it's appropriate. I iterate on others ideas with them, that type of thing.

I would ask those around me what they thought of an approach- not because I was worried mine was wrong, because maybe they'd have a fresh take and could help tweak it for the better. This warms them up to collaborate. They will likely start doing the same to you, then you'll both come to a mutual respect for where each other's strengths and weaknesses may lie, but you've formed a bond of comraderie that should keep you well regarded. It's important that most of the time when you're asking for input that you've got the problem nearly licked- no one wants to work with the guy always asking how to do his job.

Those are the main ways I've built strong relationships in the office. I say hi to people as I pass buy, grab the odd coffee with whoever, and chat about sports (I happen to root for all of the rival teams up here, so that breeds a lot of conversation).

That's it- my secret is that I just behave like an okay guy most of the time and I don't stay silent and keep my eyes to the floor.

Its easy to make something that amplifies, but he's trying to make something that provides specs maybe 10x to 10000x better than human hearing can detect, which is much harder. You can build something that outputs 0.1% THD and you won't be able to hear it, but he wants (wanted?) to build to 0.001% THD and he's got the rather expensive test equipment required to prove it.

JDS labs sells a PCB for less than the cost of shipping (you'll spend more on UPS than on the board) or a full parts kit for $60. This has been around for years and I've been tempted but haven't built one. I just checked JDS and its still in production and in stock. Being CC- licensed there are probably other places to get PCBs and kits.

They were arrested for drug traffic, not bitcoin money-laundering.

Not the smartest individuals here. How did they think they wouldn't get caught? Seems like another anti-bitcoin peace article which ends with the mt gox failure and this gem: "Bitcoin’s reputation was also damaged when US authorities seized funds as part of an investigation into the online black market Silk Road.". So that means the dollar and euro's reputation are damaged every day when funds are seized as part of 99.9% of criminal investigations?
I was recently in the home of an old friend who reps for a few ultra high end audio companies. The entry level speakers were $30k. The mids, $90k. The 700lb top shelf models? $220k.

Some things exist purely so they can have their purchase price shared and in the instance of high end audio, I can only imagine the margins involved.

If this guy made the waves the article implies then someone in the industry tracked him down and incentivized him to go away.
I think you're mixing up the science itself and the reporting on it. If a paper was published saying that sea level rises were going to be 20% lower than expected I wouldn't expect most people would ever hear about it. Or if they did it would be reported as showing that sea level rise was even more of a threat than we had believed.

If you want the truth the IPCC reports area great for providing the scientific consensus along with the (large) uncertainty we have about exactly what climate change will look like.
No, it wouldn't. Categorically.

If everyone repaid debts, then lending money wouldn't require interest. Interest expresses the danger that money may not be repaid as, for example, during bankruptcy proceedings.

Yes, you're right, I thought it was like here, in Portugal, but they actually block IP addresses and/or use deep packet inspection to do it, as far as I researched now.

I know it's not as sophisticated as the blocking in China, and a comment on reddit on a thread that I read yesterday (https://www.reddit.com/r/europe/comments/41s7z8/the_first_no...), made me think that it used DNS only.

EUians: Anything to watch out for when your company gets acquired by a US comp?
A friend of mine works for a tech start-up in a western european country, which has just been acquired by a US company. No significant stock options are at play. My friend is just an employee, not a founder. There's always the threat that they'll make everyone redundant, but let's ignore that for now.

There are many legal and cultural differences between the US and Europe, but you don't know what you don't know. I wonder if anyone can expand on any other differences? Will the new US managers come in and expect something that's totally illegal or totally out of the question. I don't know anyone who's worked in both EU & US, so I don't know what the differences are. Has anyone been through this before and have any advice of what to look out for?

It's better for everyone if this goes smoothly, so any help anyone can give would be great.
I would agree with you that most adults are not creative, as it gets knocked out of them at a certain age. We live in a failure averse society and as soon as a child feels embarrassed by a failure they went through it's pretty much game over for them for whatever that failure related to.

I would tend to agree that there is a dirth of painters, musicians, etc in the world. Of my close friends only two of us can play a musical instrument. I think I have to agree with you that easily accessible programming is never going to result in lots of people programming.

In a lot of ways universal programming has gone about as far as it will go. Learning how to program (let me be clear, I do not mean learning how to be a good software engineer) now is actually easier, IMO, than learning a musical instrument. Of my closest friends, two of us play a musical instrument, but three of us program: there's me, the SE, my friend who is an Urban Planner and knows GIS software and R really well, and my other friend who is a patho-biologist and knows Python and R.
> This website is a portfolio piece for a 21-year-old university student hoping to find an internship. In my opinion, it's an impressive demonstration of his design and technical skills. It certainly says a lot more than the average 21-year-old's resume listing what courses they've taken so far.

I'm actually a bit baffled. He's not just a student, he actually studies "interface design"!

"I am 21 years old and study interface design at the University of Applied Sciences Potsdam."

Of course just a list of what courses you've taken so far isn't very sexy or interesting. You don't need to list them explicitly. But if you do claim to study a particular field or industry, you should at least demonstrate that you have taken some courses (in particular on the topics you're passionate about), did interesting projects to complete them (there must be, even tiny ones), what/that you learned from them, why they matter.

Doesn't need to be very explicit, but there's literally nothing on this page, nor on his personal website indicating what he learned studying interface design. Drop some names, terminology, textbooks, works, important research. Show us how "I study interface design" means more than "I'm working to obtain a piece of paper that lets me claim I studied interface design".

Ugh. I have hardly any type problems in my Ruby code. I've gotten very good at recognizing implicit state and capturing it in a properly instantiated object with a well-named class. I daresay that if you don't have this skill, a type system isn't going to help you much and you're going to get nasty bugs anyway.

The problem in Ruby is nils, and you'd have the same problem with the same solution in a static language; creation of a duck type. You can't get away from duck types, whether it's a maybe type or whether you perform nil-checking at the earliest possible opportunity. You learn with time and experience how to deal with inconsistent data. Ruby gives me the flexibility to do it without a lot of boilerplate.

If you don't mind the process of finding something (or waiting for something to come up) on eBay too much, I recommend looking for used photo/film equipment out there.
I cheaply sourced two photo/film lamps on eBay.
One is a 500W LED lamp and somewhat blueish, the other is a 330W fluorescent, but of very high quality, it's a very convincing daylight tone (not at all greenish). Especially the latter makes for a very nice room light.
Both were barely used, yet substantially cheaper than new.
The advantage is that you can easily change their angle on one or two axes. I originally bought them for photography and then started liking them as regular room lights, only to later even realize that I basically got myself SAD lamps.
EULA's and binding arbitration clauses are not valid when up against negligence. You can not legally waive negligence in most countries, no matter what a web form or paper contract says. It is not legally binding.

Xkcd's explanation of possible planet 9
I ran across a very interesting example of this recently. In a new tab take some time to analyze this chart for yourself and what you think about it.

http://geekologie.com/2009/03/percent-of-student-virgins-per...

... done yet?

So, firstly I see that as you go toward more rigor, overall the rate goes up, with studio art (no rigor, it's just a humanities field) at the left and mathematics (full rigor, fully abstract) at the right. Like this - https://xkcd.com/435/

Interestingly, computer science (of interest to people here) actually isn't as far right as you'd think.

But what pops out to everyone!! There is obviously one MOST interesting fact in the whole figure, the 0 for studio art. That really got me thinking.

Granted, this isn't the perfect example because it's not just 0 as opposed to 5-7 - the next higher one is 20%.

But what you really start thinking is stuff like - "Is it that they didn't really have many subjects, just 2 or 3? what is n? Is it that these people are lying? Is it a real fact?" and so forth.

The fact that it's 0 instead of a few percent immediately raises some questions.

Roskomnadzor "works" by publishing a list of IP addresses and domain names for ISPs to download. A copy of it is leaked to http://reestr.rublacklist.net/ in real time. Each ISP implements blocking in its own way: DNS blocking, transparent Squid proxy, firewalls or nothing at all sometimes. Nobody really cares if something is actually blocked. BGP hijacking for the purpose of blocking websites is really unlikely at this point.

No debugger and not easy way to cut and paste, as its all in a web form.

Fuck that, I am a software engineer, I usually read data from databases and name my variables properly and use tools to help me understand the problem, not hinder myself.

> Not really. Maybe that's why nobody invented anything with a diode in the signal path before computers were commonplace right? Like radio and guitar distortion pedals

No, those problems were solved via ultra simplified models. E.g. The current through a diode is described as I = I_0 \Theta(U - 0.7 V). And the rest was done via try and error.

> Sure, let's forget the math and make engineers totally dependent on numerical simulation without knowing the basics, I'm sure that'll work just fine

How about, lets learn how to solve every differential equation you will ever come across in electronics using e.g. Runge-Kutta.

> Just call .sort() and you're done!

If you want to get shit done you do exactly that. This is a great problem of many fresh CS graduates. Instead of doing the actual work they would rather first implement their own sort function. In 99.9% of the cases it is a complete waste of time.

> Also don't forget Digital Signal Processing, that also relies on that "useless knowledge"

In Digital Signal Processing you mainly need to Fourier transform and know the properties of the sin(x)/x function, Nyquist, Shannon etc... Learning how to solve a very special case of systems of differential equations using the Laplace transform won't help you there at all.

"Let’s take a quick detour and look at vibration damping. Vacuum tubes, and certain components in very high gain circuits like phono preamps, can be “microphonic”—vibrations can affect them in audible and measurable ways"

OK, I'll do the reading (verbose-ness!).

The quote above makes a degree of sense - I can remember valve based consumer electronics and having fun with the microphonics. Dad used a piece of dowling with a grommet on the end to check for valves that 'rang' so he could replace them.
Why are people so obsessed with publication bias and statistical power? Those are just two of the dozens of reasons why published research is unreliable, and it's not even clear that they're the most important ones.

Ask HN: How to deploy a microservice architecture in a VM without root?
I am currently evaluating solutions for deploying microservices architecture in a virtual machine without having a root. Our architecture currently consists of:

- RabbitMQ

- PostgreSQL

- Golang services

- Python services

- Closure-based web dashboard

We can't use containers as their daemons usually require root access (e.g. Docker, LXD) - Are there any container technologies that would work on RHEL 6 without root?

Most promising solution so far seems to be to ship a chroot'ed environment, but that also requires a binary with root's setuid.

So how would you solve a problem of shipping and running pre-configured microservices architecture easily in a non-root environment?
