Well if energy companies can make profit they cant run sustainably; which means others dependent on them cant grow either. Since when do people on HN started thinking of profit as opposite of "forward thinking" is beyond me.

Of course I wont count government subsidies as profit because after all the poor Americans who end up paying tax aren't paying for that energy willingly. Arguments for massive government subsidies such as $8K for rich people's car Tesla is that this might speed up the economy of scale for these businesses and that it will eventually be affordable for ordinary people. ( Of course also the dubious claim that this all might help reduce some environmental problems.)

I am worried that specific government subsidies for say Wind or Solar might be hurting some innovation in radically different directions.
Maybe use 'new Image().src' to preload the images?
The optimization should be ~0 year hardware patents, and ~0 year software patents. All the patents will do is slow down market deployment and innovation.
It seems that oCaml has been working on iOS for at least 4 years: https://news.ycombinator.com/item?id=3740173 yet you hardly hear about it.

Anyone care to discuss long term support? How brittle is it with iOS upgrades, for example?

Any Swift examples that I can include in my Swift Weekly page?

The people I most fondly remember working with somehow managed to become really good while keeping all the good parts of being juniors.

At one company I worked for, there was one guy, a kid, really, the youngest person on the team, who was approached by everyone for help. No matter whether the problem was front-end javascript, back-end python, something to do with algorithms or a difficult regex, he could instantly switch context and help out. And if he couldn't help, he'd come over a few hours later with a better solution than you had thought up in the interim.

And yet, he was ever humble, smiling, and never seemed bothered by being interrupted. He didn't make you feel like you were stupid while at the same time giving you a solution and properly explaining it. Never mind that he was half your age, it never felt humiliating.

He's the kind of programmer I aspire to become, both in skill and attitude, and I wish there were more like him around.
"A Bayes Factor Meta-Analysis of Recent Extrasensory Perception Experiments"[0] is a good read in this area. It extends the analysis of psi with Bayes factors and underscores how the priors, and a causal mechanism, really matter.

Haskell has a mode, where you everything is a comment by default, and lines of code have to be marked as such.
Interesting that they're in Northern California and get Seasonal Affective Disorder.

I live at a similar latitude (except in the Southern Hemisphere) and have never considered that it would be a thing outside of essentially polar latitudes.

Over the past couple of winters (I moved further south a few years back) I've had some atrocious winters in terms of mental space. Maybe this is something I should look into.
You might consider having a link to your work portfolio. A web site or on line CV can be a bit more expressive than a standard CV. I give potential computer vision clients a link to my computer vision portfolio (www.3drocketsurgery.com). I give other clients a different site.

Now when you email a potential client, they just click on a link. It's even less "friction" than opening a rather dry CV document.
hey! yeh, everything's going well. the scans were done to help diagnose some things about 2 years ago. nothing turned up in the scans though.

thanks for tweeting me earlier. i had no idea this was on Hacker News! lol
That page yields a 504 Gateway Time-out right now. Cached at http://webcache.googleusercontent.com/search?q=cache:jH9Wl8R...

The demo at http://tatiyants.com/pev/#/plans works.

Unfortunately it has some glitches.

Hints for using it:

* In psql use \o plan.txt to redirect the output of explain to a file. It will be a long output because you must use EXPLAIN (ANALYZE, COSTS, VERBOSE, BUFFERS, FORMAT JSON) and copying it from the terminal won't be fun.

* Remove the first two lines (header) and the last two (footer) leaving only the json data. Remove all the + characters at the end of every line. Suggestion to the author: the tool should handle that.

That said, it works. It really is much clearer than the output of explain in the terminal and as a result I'm googling how to speed up sort now. Thanks.
Jeff has been maintaining it since, he just released 4.02.3 which is the latest available compiler http://psellos.com/2016/01/2016.01.the-minor-drag.html with iOS 9.2. Not that bad I'd say, that's pretty much bleeding edge. I don't know about swift because I don't know how to compile swift into an object file. Swift is not worth the hassle for me right now.

FWIW apparently it will be officially merged into the mainline compiler soon enough.
And in Haskell. At least for the more abstract bits of code.
See the hints in my other comment.
Interesting. Derren Brown, English mentalist, describes in one of his books how he deliberately failes every now and then to make it more convincing there are pschycic abilities at play instead of a mechanic trick.
And for the same reasons: some things are so abstract, that there's not really a better name for them than line-noise symbols.
Good observation. I remember 'lol' becoming popular and it was mainly used ironically. Now it's normal and I only vaguely notice when people much older than myself use it.
I doubt the scans really high enough resolution for a meaningful simulation --- I don't believe MRI scans can capture the complete connectome of a single human brain, let alone any subcellular data.

e.g. the Human Connectome Project is still working on capturing the macroscale connectome, that is, high level structures only. Recording the microscale connectome, that is, the neuronal structure, currently requires destroying the brain you're analysing.
I have that same reaction and feel old about it. The other day I came across a stand-up comedy video of Donald Glover (who I loved as Troy in Community), and the constant 'likes' made me unable to enjoy the video. Odd, that.
This doesn't seem particularly illustrative without some context. or significant figures.

I'm all for contrived examples when they are used to help understand, but this feels like an artificial comparison.
Are you perhaps a 25+ millennial? I'm at the front (as in, the beginning) of what is generally called the millennial generation, and I feel old around the younger millennials. 20 years is a long time.

It sounds to me that Bitcoin is a lousy medium for money laundering. It's unclear to me whether they laundered money by supposedly buying and selling bitcoins or converted shadowy assets into BTC and then back to physical currency, but in both cases the transactions can be tracked back in the blockchain so you'll not only have to make a good story of where the money came from but also, if and when the authorities get interested, make sure that how the BTC is moved around reflects that story.

But merely converting BTC to cash via ATMs doesn't even sound like laundering to me at all, just conversion. You would still need to explain the cash you've acquired if you intend to buy something with it.

Money laundering itself is not for those in a hurry. To plausibly launder money you need a service business with costs that are rather fixed and customers who can plausibly pay with cash. Then you can have as many "customers" as you like and nobody can really tell how many you really might have had but depending on how you set up the scheme you can report a reasonable income over the months and years, pay the taxes and thus turn the money legally earned.
Childhood is my go-to argument in favor of 'everyone is creative'. I've not talked to a single person who wasn't highly creative as a child, and just realizing that makes me sad sometimes.
Ask HN: How to start and build a successful hackerspace in your city
Like many other smaller cities, the place I call currently my home (Zagreb) has no hackerspaces [0].

Being a newcomer/foreigner in this town, I'm a bit lost tbh finding connections and common interest. Meetup groups are academic and sleepy here. Paris, Berlin and London have great hackerspaces and I can usually find like minded ppl quickly. I think it would be cool to see hackerspaces also in smaller cities and where old + young guys can interact and teach each other.

Has anyone here been involved with building a hackerspace?

How are they are organized and set up?

What is the best way to figure out if there are enough people are in your area to make it a viable project?

Who sponsors these places? e.g. Is it individuals who are providing their private garage or companies who provide the facility? Do I approach companies and ask them if they want to cover some of the facility/running costs?

I can see many of benefits why companies would encourage these spaces such as helping their engineers get broader hands-on skills during after-work activities. And a great network effect for the company where people can easily find a new colleague in these places if their company happens to have a job opening. (all without recruiters and with lower risk because the persons skills are known etc).

If anyone can share some experience? Thanks

I'm starting to be afraid that one day my brain, memories will be pushed on git :<
Hey! This is pretty cool.

We worked on something like this for C# protobufs. Check it out:

https://github.com/HearthSim/proto-extractor

I'd be curious to see if we can work together on this stuff.
I've never been convinced by that argument. Looking back on my memories as a child, I wouldn't call myself creative -- I think that's something that I've developed as I've grown older, not something I was born with. Certainly, to a degree, children are curious, but that seems largely out of necessity (to learn e.g. language so you can express anything, not necessarily something creative).
I live in Norway, and used to have a big problem with SAD and longer-than-24-hour-cycles. I tried a few of the commercial lamps like he did, and my experience was similar. They helped some, but not enough.

My current solution is to take a 1 hour walk outside every day around noon. Also, I've stopped sitting in front of my computer or TV 3 hours within bedtime. Instead I usually spend my late evenings reading paper books.

This has solved the longer-than-24-hour-cycles and most of the SAD (it also seems to have completely cleared up my acne). However, on days when it's overcast and kinda dark, I still notice some SAD. On those dark days, the kind of lamp that he built probably would have been nice.
Absolutely epic... need more samples though :D

I will be starting on a tutorial project soon for my employers, developing an API and frontend client in Clojure with compojure-api for backend, and ClojureScript + reagent for the front-end, with possible fun diversions into Raspberry Pi support and even mobile apps if I can puzzle my way through the still early React Native support for ClojureScript.

In the meantime, for the basics, I started with the Koans. http://clojurekoans.com/ I found them a largely excellent way to get up to speed with the language by doing some actual coding.
Can i suggest we call the spikes "blips", if for no other reason than to avoid confusion when talking about "spikes" with project managers and product owners.
Try SAD at 64 North. No picnic. I'd really like to try s light but don't think I'd have the patience to sit in front of one long enough. If it could be made bright enough that you could have it overhead and work at the same time that would be brilliant.
Wow, wonderful work!

As an additional information about already existing execution plan visualisation tools:

Depesz has written the classical PostgreSQL Execution Plan Visualiser years ago.

http://explain.depesz.com/

Of cause it is not so nicely pretty as the one from Tatiyants, but I use it now and then and it became a standard explain visualisation tool for many PostgreSQL users.

The table format from http://explain.depesz.com/ is very useful and one can understand a lot of details about your execution plan without the need to visualise in the form of a graph.

Also the default execution plan visualiser in pgAdmin looks really cool.
I have a big gripe with the design of the finder window, and with all similar good looking designs from many mockup-designers of interfaces. It only looks good and practical at the same time when you've taken a printscreen, scaled it down 60% and don't try to read the text.

If you try to actually use this on a normal sized and normal resolution screen the text would be too small to read. So, to solve this you have to increase the text size, but this means each element becomes too big so that nothing fits, to solve this you have to reduce the padding of each element but then it doesn't look as good anymore. The contrast of the text is also too faint and if you make it more clear the "wow-looks" of the concepts are all gone. I think this is why you hardly ever see designs like this in the wild.

What I mean is, open this picture[1] and resize it to comfortable reading level, after doing so i can only see slightly more than half of it vertically. Things that previously looked like pretty design elements now just seem to waste space, like why would i need a thumbnail of a map and a movie-cover on my start screen?

It's just like architects designing the block of a city, they always show fancy renders of the place from above(?!) in the best weather imaginable. But that's not how people will actually perceive it when being there because then you see things from street level where it doesn't look the same at all.

Feeling bad because it's winter? Yee-ikes. Plant problems. I can't believe it's actually called SAD. Luckily summer will be here again and we can all be STOKED.
To an outsider like me it looks to me like all the basic things about audio have been solved and competition is only really about things you hardly can perceive or total hocus-pocus. Still some people seem to still earn quite some money, so it's no wonder that there's a toxic environment of people trying to protect their income source when it's not really backed up by offering a product that's really better than something much cheaper.

I don't see any info about the spectrum produced by the bulbs he recommends. Color temperature is one thing, but that's equivalent to describing a chord with just the root key. I suspect that a spectrum as close to the sun as possible (including UV and IR) is better.
>I've seen multiple articles talking about people as young as 10 years old creating apps. This wasn't possible in the 80s and 90s.

In 1980s UK kids were writing games that sold in their hundreds of thousands.

Maybe not 10 year olds, but 16 year olds like Christian Urquhart, Matthew Smith, Eugene Evans are well known names I can remember off the top of my head. There were other, less known, even younger kids than that writing popular games, and even more younger kids learning to program.
Any particular reason that you suspect that UV and IR are important, or is this just pure speculation?

As a teen on weekends I worked a lot on filmsets as assistant to a lighting cameraman. Switching HMI lamps on was really amazing, the mood of the set changed in an instant. It was quite energetic, so I completely get what the author is saying.
They usually were positioned outside of windows, allowing for a stable consistent sunlight simulation across scenes.
While Vit D helps me, additionally using a 10k lamp is like night and day, if you forgive the pun.
All our dependencies in maven and bower are locked down. However, even though you can do the same with a buildpack, this is not exactly what heroku and dokku will do by default. The documentation [0] specifies a way to do so with a git based system, but all commands given on that page won't specify a tag.
Note that this was not in production, like I said in the article, it was an internal release.

Seems to conclude latitude doesn't make any difference, which is surprising. But there are other papers with the opposite conclusion.
latest version of Chrome (48.0.2564.82) should support all keyboard layouts
This was my experience as well. For two years I lived at a latitude where I got about zero daylight for 5-6 months per year. My SAD-lamp helped a little (<10k lumens), vitamin D helped a lot.
Threadbase is a really cool project. I'd definitely use something like this if it were available in my country. Good luck, I hope you succeed and go global.
You got me there for a second.

I thought you would be talking about the current PM's undeclared payments, or how he removed financial aid for old and disabled people then made the country pay for his father's nurses; maybe about his party destroying evidence about undeclared payments likely to be bribes, the country's money spent on the pressure against Argentinian judges to not judge relevant figures from the Franco era or maybe about the sister of the current King stealing money from my fellow countrymen or even about Botín (now deceased Banco Santander's founder) and how we forgave him from declaring a couple of thousand million Euros.

Can't see under which reasoning that's the first arrest - it has to happen, doesn't matter the order, but it strikes me as an odd choice without formal accusation.

But anyway, it has been long since I've lost hope for a better Spain. We have what we deserve.
This is great and thorough explanation, thanks Dave for following all the issue deep down the rabbit hole :-)

>Even if you don’t create the final product with all it’s amazing features and sparkly buttons; if you have at least something out there that works, then there’s always room for improvement. Over the period of 6 months, I’ve revised the design about 5 times, changed the entire framework twice and had to completely erase and restart the database thrice. If I had continued to improve with I had in the beginning then I could have reached much further ahead. Furthermore, if I had continued with whatever I had, it would still have been better than nothing.

I'm not sure he articulated this point well. But if I understand what he is saying, he should have improved on what he had not recoded the database interface and the framework.

I would like to understand what drove him to redo so many pieces instead of incrementally improve the system.
It could well be. Though I suspect it's more of contrarianism in a minority of people. We also have man-on-the-moon deniers, etc.

What surprises me about climate change is that they're somehow managed to show causality between one non-repeatable event (people starting to burn fossil fuels) and one other event (global warming). Holy cow causality is notoriously hard to confirm when we can't manipulate the causes. When the cause and effect each only happen once, it's surely almost impossible. I'm suspicious of that extreme confidence.
Cosine to the fourth power is the wrong formula, it is for camera lenses and takes into account the apparent size of the pupil from both sides, as well as distance attenuation for objects on a fixed plane. Solar illuminance is proportional just to the cosine, no power.
As the research engineer on the Virtual Brain simulator to which I linked, which we apply to improve e.g. epilepsy diagnosis, I can say that those scans do have enough resolution to capture global properties of anatomy and dynamics of brain networks.
Hi Kleiba

years ago I studied a bit AIML and also recently I see that Ruby language implementation is a bit obsolete.

My feeling is that AIML are not maintained / growing, but the principal point I a bit discarderd AIML is that it seems to me not faiseable to do a "deterministic" workflow (just let consider the e-commerce purchasing workflow I described in my project http://www.github.com/solyaris/dialogs)

How Ember.js saved my life

"Designing around patents is, in fact, one of the ways in which the patent system works to the advantage of the public in promoting progress in the useful arts, its constitutional purpose."

To me that just sounds stupid. It's akin to the argument that breaking windows promtes growth by stimulating the glass industry.
MySQL Workbench recently also got a visual explain option.
This is very useful, don't know why everyone keeps struggling with a text format (especially for large explain plans).

Yeh, sadly enough the Dutch media and government try to totally hide this in their stories. Bitcoin == Money laundering, and TOR == THE DARK WEB. Period. [0]

The article is full of misdirections and word plays.

It starts of with "Bitcoin is used by criminals, because the currency is not controlled by banks and thus there is no supervision". This is the first misdirection, because just because it's not controlled by banks doesn't mean you cannot supervise it. The core idea of bitcoin _is_ supervision. It's a public ledger.

It then continues to support their argument by saying "Bitcoins go back and forth in a _closed_ system of users, so authorities can't see it". Which is just a plain lie. Bitcoin is an _open_ system. Anyone can see any transaction.

The article continues:
"As soon as the bitcoins were turned into real cash, the money was turned into cash at banks. They finally stepped to the police, because their warning systems detected large amounts of money being transferred".

So apparently it _was_ really easy to track down? They detected the weird transfers and were able to find the criminals. Seems bitcoin actually saved us here? That totally is the opposite of what they told us two paragraphs back where they said "there is no insight at all in what happens with bitcoin"

The article then continues to mumble about how TOR == Dark web and it's just painful to read. I hate media.
Now my mom starts asking me akward questions about hard drugs because I have a TOR and a Bitcoin sticker on my laptop.
