Psynesthesia - A python program to convert sound to color.
Now, i have something called synesthesia in the specific form of musical chords, so i decided to write a program that did just that.

i started with the idea of a tuner, which gave me the idea of Hz. since tuners don't actually "hear" the pitch of what the instrument is, it just measures the frequency, in Hertz. so i coded a little function using numpy and pyaudio to take an input .WAV file and spit out the frequency.

Great. Now what?

Well, i had to somehow convert that into a color. for the longest time, i was confused.
Now, theoretically, its impossible to actually convert sound to color, but we can do something close.

You see, light in its own way has a frequency too. however its measured in wavelengths (if i understand so correctly), but sadly, Hertz was not going to do the job for me.

λ = wavelength

λ = c/f

c = velocity of light

f = frequency

However, using Hz i found out, would just produce a wavelength too minute for our eyes to pick up. we can only see (in nanometers) a range of 750 - 380, (from dark red to violet) anything else comes off as black to our eyes. so i thought of the idea of THz (TeraHertz), which is simply attained by doing (Hz x 2^40), and now i had a frequency i could use to produce a visible color on the color spectrum.

now i could do c/THz

c being the velocity of light (3x10^8 m/s)
then even far so,

nm = int(pre</i>10<i></i>(-floor(log10(pre)))*100)

now i have a whole number i then used PyGame (which i had had some experience before with) to fill the background with an rgb color (using wavetorgb module to convert the Wavelength to rgb), then blit it to the screen.

Please remember, this script is not quite done yet, and please let me know how i can improve it, because honestly, i am a terrible coder, and i know there is always a better solution!

The purpose of requiring code signing certificates for default trusted execution on OS X was to make Apple able to blacklist IDs used for malicious purpose (and perhaps to create at least some financial/identification trail). What more would you have wanted code signing to do here?
I noticed this too. It seems really neat and I'd love to invest in it but I want to see real footage.

PATH gets set the way it always did. For example in bash:

export PATH=$PATH:<new_dir>

As for the larger question of environment configuration; we pull in a number of shell configuration scripts owned by the infrastructure teams. You are right, there is no universal way to set path due to things like "export" vs "setenv", but often multiple shells support the same syntax so you can sometimes use a config script meant for bash in zsh, for example. I had hoped that fish would be able to use csh scripts, because it shares "setenv", but csh of course delimits PATH with colons.

You say that PATH is treated as a colon-delimited string when accessed as an environment variable... Hmm. That wasn't what I was seeing, but it is entirely possible I made a mess of things, or that I broke things when I compiled it.

Anyway, it's unlikely I personally will be able to use fish. I hit many more obstacles than just PATH, but that was the easiest example and I thought I'd share some feedback.
Wait. When did this morph into an argument of the existence of God? I thought we were talking about God being some sort of preferred relativistic reference frame.

> Besides that you can obviously build a house and enter through the front door after you finished it.

You did not enter the material house - you entered the empty space that was already there, which the material of the house surrounds. If you want to use the analogy you must actually change your physical body to be made of wood and nails.

Check that he is reporting each and every time that he is playing. Ideally he should be writing the gambling in an Excel or Googledocs spreadsheet. Every one of them for at least three months.

A common problem is that the people report only the good events and forget the bad strikes. Other problem is partial compensations: "I won +$50 and +$10$ and I only lost once -$30." really means "The firs week I won +$50. The second weak y lose -$40, but it not a lose because they come from the money I had won in the first weak. The third weak I won again +$10. I only was unlucky in the fourth weak because I lose -$30."

It's not voluntary lying. Lucky strikes are interesting anecdotes, unlucky strikes are expected and boring. And bad memory and "compensations" are normal human bias. So write down everything systematically, or it's not useful to make statistics.

I found the footnote particularly interesting:

"The Moon has no oxygen atmosphere, so how can something explode? Lunar meteors don't require oxygen or combustion to make themselves visible. They hit the ground with so much kinetic energy that even a pebble can make a crater several feet wide. The flash of light comes not from combustion but rather from the thermal glow of molten rock and hot vapors at the impact site."
"obviously they think it's worth that much."?
If it worth that much for them then why don't they pay? Because it doesn't worth that much for them...
Do you really think they could get $200k in revenue front that video alone? No they can't... the guy got an offer of $40k from a Canadian Network, this is the best he could get.
However we do deserve to see this video and this guy deserve to get money for the trouble and to be able to move somewhere where he will be safe.
Crowdfunding is the best way because it's good for the crowd.

Can someone explain to me why this would be bright? I understand that this should send up a fair amount of ejecta but wouldn't most of the light be just from a reflection of the sun off of the particles?

If so, this isn't much of an explosion - it's just the most significant impact we've seen so far. I guess explosion is more interesting to the every-man.
This article and others like it are arguing against a strawman. No one ever proposed removing teachers from the equation. The idea is to leverage technology to allow teachers to reach more students and/or teach more effectively.

Sure, no online educational platform can rival a good teacher in a classroom setting yet, but that's because a good teacher is able to pick up on and respond to a lot more data through a physical interaction (a student's posture, tone, and other social cues) than a computer can online.

That being said, in theory an online education platform should be able to track all that and more. They potentially have access to an incredible amount of data including the exact amount of time a user takes to engage with a lesson, how fast he or she is typing / is able to complete tasks, even the varying levels of difficulty at which different concepts are being learning, etc. This is all stuff that none of the current online education platforms have even tried to do anything with yet.

But to say that an online education platform will never be as good as a teacher in a classroom is like going back to 60s and saying that computer image recognition sucks so we might as well stop trying.
So they're getting paid less than the going rate, at least the software engineers are. Interesting.

Have you considered many of them that are on the payroll might have other jobs and so the volume is to make up for the fact that they're not all 40+ hours full time? I think this is much more complicated than we could first expect

The reason states started running lotteries was actually to deny business to the mob. Mafia used to run the numbers games right alongside the protection racket. Revenue was mostly a side effect of a law and order decision.

I can't say I understand how anyone would be more or less upset about taxes due to the fact that lottery money goes to schools.

I agree with a comment in the story - we need a better framework that actually supports non-replayable (ie, one-time) codes being transferred.

If Blizzard can give keyfobs to gamers for auth, why cant banks include that in tech for ATMs?

More and more I think corruption and fraud are the likely reasons - those are features the establishment wants to support, not prevent... they can profit from all of it.

There are some pretty raunchy apps on the app store - did you see I'd Cap That last summer? The whole app just takes your image and adds some heavily-innuendo-laden text on top. Lots of apps have similar or worse content.
I agree that there are other forms of business organizations, and perhaps other forms of companies. For example B-corps that have non-financial goals, or simply like these guys who essentially have a successful on-the-side business, and explicitly do not want to grow it or market it in the traditional way (and hopefully have the legal protection to do so without somebody from the regular business world eating their lunch). A lot of them seem to revolve around the concept of "having enough" as opposed to "trying to expand."

However, I don't agree that any of these new models are generalizable and will take over the traditional model. VCs did not replace small business loans or Wall Street capitalization. They are an alternative path or sometimes a different step on the same path. The traditional model will contine to exist where it already does, and the new models will have to carve out new niches.

I think this stuff is cool, but I think it is going to be held back by a romantic attachment to "real".

Why not use something like the occulus rift? Instead of projecting new objects over the top of existing ones; replace the users field of vision completely.

I'd love that.

One of the guys in our hackerspace (plug: heatsync labs, Phoenix AZ) got an occulus, and we've been talking about how cool it would be to build a "virtual office" of sorts. Sit down with an occulus and some noise cancelling headphones, and have an infinitely large workspace.

2 monitors? or 1000 monitors; it doesn't matter because your entire field of vision (or your entire environment) is being rendered for you.

I think people are very attached to the idea of your eyes seeing the "real" world instead of a re-displayed one. I understand that, but I think that ideology is going to hold AR back for a while.

So, there’s a semantic trick here.

Technically, when an AdSense client targets their ads only to North American users who expressed an interest in <certain medication>, Google didn’t “sell that user’s personal information,” but… whomever is on the other side of that ad, once clicked — and their partners — have just paid Google to find a user who likely has <medical problem>.

Isn’t that selling personal information? Actually, if not legally?

Maybe you are, but in my experience 99.9% of the contractors of those places don't pay well because they don't have to. Most of the time there is someone more desperate that lowers the bid just to get the job. If everyone paid decently that would be a whole new story.
Just wanted to say that I helped build this site. It's 2009/2010-era Django site built on feincms with a PostgreSQL backend.

Originally it was a Plone site but after a year we realized it was too hard to meet the deadlines of NASA VIPs. So we moved it to Django. Also, myself and the other developers have NEVER been happy with the flash on the front page. :P
Hardly insignificant.
The massive kinetic energy must be dissipated on impact. Some is consumed in displacing the material on the lunar surface. Some is converted into thermal energy, resulting in hot enough material to radiate energy in the visible spectrum.
They're both possible and we'll have more videos very soon to show this. Filming through the glasses is really hard, we've been working on a rig the last few days and will have videos up soon.
> However, if you're in an apparently empty and dark universe, and you're interested in knowing whether you're accelerating or not

You can't. There is absolutely no test that can tell you this.

You can't "drop" anything - whatever force is accelerating you also accelerates the object, so letting go of it tells you nothing.

Thank you for disclosing your Google affiliation.

Occasionally on HN, there are comments on Google-related topics that I suspect come from Google employees/affiliates, or waves of votes that may be coming from those with a financial attachment to Google. But often on social news/discussion sites, you don't know how closely the comments/votes are entangled with the issues being discussed.

I wonder if the meteorite that exploded in the atmosphere over Russia did more or less damage than if it had struck the earth intact.

Clearly Atmosphere makes a good shield for burning up the small meteorites - but I wonder if it exacerbates the damage from medium sized ones?
Sorry, but it's not going to work anywhere near as well as they showed.

Look at the quick "From the labs" video down the page. It's grainy, messy, and raw. There's simply too much noise for it to look good. Without a significant bump in sensor resolution (it's only 320x240! https://forum.libcinder.org/topic/future-is-here-time-of-fli...), it's not possible to have both smooth and performant results.
> The problem is that the state constitution and politics makes it easy to get rid of revenue, but really hard to get it back.

As it is quite easy to start spending but not stop.

Cut spending. Deal with the actual issue: pensions. The vehicle licensing fee 'problem' is just a red herring.
These tools are amazing. Wish I had had something like this years ago.
True, but then as a cyclist we'd go to prison for killing someone. That's why I have well maintained disc brakes and a healthy respect for traffic signals (as I'm sure you do, also).

This happens in Ohio too. From the Columbus Dispatch:

"School leaders have complained for years that the state engages in a shell game; for every extra dollar generated by the lottery that goes to schools, a dollar is taken out of the state’s general-fund allocation to districts across the state.

The shell game — difficult to prove in a multibillion-dollar state budget — was briefly exposed in late 2001 when Ohio added Powerball to the lottery. The state estimated $40 million would go to schools from the new game, so lawmakers promptly reduced general-fund money for schools by $40 million."

The ejecta aren't tossed about due to recoil they are lifted out of the ground by an expanding sphere of vaporized rock. And that vaporized rock glows because it is superheated to thousands of degrees, that's what creates the bright flash.
That's definitely a fair point- "experts" have very different search behavior from "novices", and could potentially get more benefit from personalized search support.
What do you find that is different? I've never had a problem with type hierarchies or Find Usages in Java (not counting JSP - JSP support is terrible).

For JUST Java, IMO Eclipse wins for me.
Really? To occlude real objects, the glasses would need to have per-pixel adjustable transparency. They look like Epson Moverio glasses[1], and I don't see anything on Epson's site to suggest that they can selectively occlude light, but I'd be delighted to be wrong.

I'm a little bit skeptical of some of the artist renderings here. Being a researcher in the computer vision field, rendering accurately onto arbitrary surfaces simply is nowhere near this precise. It requires an extraordinary amount of scene understanding. Factors like shape, surface normals, illumination, reflectance, etc. all need to be separated. These properties are extremely entangled together and state of the art methods require a great deal of computational power to do significantly worse than what's being shown here.
Happiness is not an illusion, it is actual neurons firing, hormones rushing and what not. Of course from an abstract standpoint it is meaningless, but you can catch the ball nature has thrown you and play. There is a reason humans haven't gone extinct yet.
It's complex, or like with project management, there seems to be so many different use cases, and also legacy ideas and workflows. For example for some people tags are the most important thing in a bookmarking service (even you when you have a full-text search for everything), and for some they're just annoying.

What I think about it, is that bookmarking, most of the time, isn't bookmarking anymore. It used to be that to bookmarked a site like "yahoo.com" to your browser since domains were hard to remember. Now you "bookmark" things, like the OP described, to use the them now or later.

Also most of the time you care more about the content (article, image, video) than the url or the site. What I think bookmarking is, is that it's a way to research, use and understand information on the web.

Why I collect or bookmarks stuff, is because it's my way to learn and remember. It's like making notes on lectures, so you actually try to pay attention to what it's being said (and sometimes you just want to focus on other things and save things for later.)

So having those basic features in a different form every now and then was a dealbreaker how? Also - How is Windows much different?
There was a relevant update to iTunes last night (or earlier this week) for both OS X and Windows. It is usually these types of updates i keep an eye out for, as it is most importantly an update to certificate validation.

CVE-2013-1014 as it impacts iTunes for Mac OS X v10.6.8 or later, Windows 7, Vista, XP SP2 or later (http://support.apple.com/kb/HT5766) -

"Impact: An attacker in a privileged network position may manipulate HTTPS server certificates, leading to the disclosure of sensitive information

Description: A certificate validation issue existed in iTunes. In certain contexts, an active network attacker could present untrusted certificates to iTunes and they would be accepted without warning. This issue was resolved by improved certificate validation."

There were almost forty other CVEs for iTunes on Windows. And just a last bit - the discussion and quality of submissions here at Hacker News has taken a substantial fucking nose dive in the last year. I change my name every so often, but i can tell you that i've been here long enough to say that.

What about browser -> save as -> save as type "Website, complete"? Not really a library, and not really something you could do retro-actively to urls already bookmarked without revisiting the pages, but it sort of works.
