What???? Marketing by FUD? Why should the above statement be true? The implication is that if you don't get your solution out now, you need to wait 20 years for the replacement cycle? If anything, early entrants to the market are going to make a lot of mistakes. No way the first implementations are going to be around for 20 years.

Ask HN: Can I get some feedback on my business idea/landing page?
Hey guys,

I would love some feedback on my business idea. I haven't "officially launched" yet so I might change up some things, but the content that is on my landing page hopefully sums up the service I am offering.

As far as pricing goes, I will probably raise each plan $20 or $30 but I am not sure yet. I also plan on adding a live chat widget (olark.com) before I start promoting the site.

I seem to have a horrible time thinking as a non-technical small business owner instead of a developer so I would love any feedback on my copy.

Thanks for the help!

> I disagree

I assume because you misread the example given there. If you note that $glob1 and $glob2 come from what should be different lists (all files in working dir and all files ending in .c in the working dir), then $glob1 and $glob2 should contain the first item each of their respective lists. That's exactly what the documentation says should happen.

> You would expect what it says in documentation, and it says it should iterate over the list.

Unfortunately it doesn't even do what it says in the documentation consistently. I have another comment here that outlines that fairly thoroughly. The behavior is very weird and specific to glob, and is not documented accurately.

"Preedy said that when Bertha was being built in Japan, one of the tests performed was to turn on the motors and rotate the cutter head. That’s when testers heard a noise and took Bertha apart. They found that some parts of the machine weren’t moving properly and caused “some metal-on-metal contact and basically damaged the seal assembly for the main bearing,” Preedy said."

This was a manufacturing problem discovered when it was first spun up in a test, as far as I can tell not even involving any digging, just making sure everything functioned correctly (e.g. what NASA didn't do with the Hubble mirror).

The developer in me likes this very much. I mean, Taxonomies! Unfortunately many non-journalists tend to romanticize and over-complicate the craft. Journalists care mostly about the story telling, and it's not clear to me how this translates into a better story. I believe this to be a (beautiful and well-intentioned) example of overengineering a domain model that, at it's most basic, involves just titles, deks and content such as text, images and video. To me it does not clearly push journalism toward a more profitable and sustainable future and thus, is a distraction from more challenging problems at hand.
I don't like the idea of developing for current machines. With the constant advances in computers the next generation of applications, "developer apps" should be made for the next generation of computers, meaning that its okay if it's a bit of a hog. I mean, 200MB is just a drop in a bucket now.

Light pollution and LED lighting is complicated.

LEDs appear to reduce light pollution as they are much more directional. They are also far brighter than sodium with better color rendition.

Because of this we get images that look like light pollution is reduced:

Unfortunately, light reflects. Particularly off of snow. What appears to be a reduction in light pollution is in fact a dramatic increase in brightness, resulting in lower exposure photographs that appear to have darker darks.

I guess you aren't really experienced with the two languages then?

For example, in the programming language shootout (http://benchmarksgame.alioth.debian.org/) the regex DNA test has a 5x lines of code difference between Python and C. That was code written by experts in each of the respective languages, and highly tuned for performance. About half the lines in the Python entry are just string constants that could easily be exported to a data file, which would give you almost exactly the 10x difference this slide represents.

Now, that doesn't mean it is always so, but it's totally reasonable to see that happen routinely.

> What happens when you start combining waves together to create more complex signals

Aliasing is a linear effect. If L is an operator that aliases at some frequency, L(Aa(t) + Bb(t))=AL(a(t))+BL(b(t)). Aliasing is in fact multiplicative! Any time you wish to understand aliasing, you really want write the signal multiplied by a dirac comb (a train of equally spaced infinitely narrow pulses). If you wish to understand nonfinite sampling widths, it's effectively convolution with the shape of sampling pulse... which looks like low-pass filtering. Ya dig? This is the frequency on your scope that's stupidly above the sampling rate. Why's my scope have a bazillion ghz bandwidth when it only samples at 4 samples oer week? It's because it's real good at getting you that signal, aliased down into the sampled signal.

> what effect does aliasing really have on an audio signal

PRECISELY the same effect it does on video, except in one dimension, and you haven't understood aliasing until you've understood it in one dimension.

> Is is possible to show that such information either isn't lost

It's lost. Completely... if done properly. First you need to understand Whittaker-shannon interpolation. The result of which is that a CONTINUOUS BAND LIMITED signal is PERFECTLY represented by a train of discrete samples. This is WEIRD. Really weird. Prove it to yourself. It's VERY important in sampling. Say you then perfectly sample a signal with harmonic content ALL over the place. EVERYTHING gets mirrored down into your view, if the dirac comb has infinitely narrow pulses. So at the least you lose frequency information! You only know the original frequencies modulo the nyquist frequency! If you sample CORRECTLY, you band pass filter your incoming signal so there's NOTHING above the nyquist frequency, then you have a perfect digital representation of your original signal.

If you wanna understand signal processing, you really can't use your intuition. Practice understanding things in the frequency domain and time domain, and generally there's only one proper basis to understand a phenomenon. Filtering is best understood in the frequency domain, for instance. If you try to understand filtering in the time domain, you might begin to think that it bounds the speed at which the signal can vary but that's not a useful intuition. Aliasing is best understood in the frequency domain, since it moves stuff down in frequency mod the nyquist frequency. If you try to build an intuition in the time domain, you'll think that there's some signal lost when you multiply by zero between pulses... and you'll guess at what it was and think "distortion" or whatever but what's lost is just WHERE each frequency is... so be very careful about what basis you choose!
I thought it was DB connections over radio waves just above 20 meters. Also, it's MHz, not Mhz.
> Why wouldn't water be one of the by products of the big-bang

There weren't any Oxygen atoms around until long after the big bang, and only a handful (in cosmic terms) of non-Hydrogen atoms.[1]

H2O molecules couldn't form until Oxygen had been synthesized, which occurs when a star exhausts its Hydrogen and begins fusing its Helium[2]. So water probably didn't exist until well into the the first or second generation of stars.

I agree that Hz seems to imply a periodic event.

There's commercial in the sense of "used to help make me money" which is how C/NC are normally distinguished.

And there is commercial (e.g. advertising, marketing brochures, etc.) as opposed to editorial use. Which typically requires a model release in addition to an appropriate license for the photo. Frankly, it's really up to the user of the photo to determine that they've cleared appropriate rights.

The New York Times (a for-profit corporation, well trying to be anyway) can print any news photo without a model release because that's editorial. However, if they use a CC-NC photo, they would presumably be violating the terms of that license.
IE, you got marketed to. That's fine, I'm just saying, I don't think they did something new

Ratios:

It depends on the private tracker. The key is to reciprocate - I initially did poorly on what.cd and had my downloading privileges revoked. I got on Bandcamp and found free albums and just started uploading FLAC content. Now I'm a power user with a nice buffer.

I had better initial experiences on other private trackers but I prefer what.cd's ratio system.

Upload Rates:

what.cd is pretty good about this. I have yet to find something I wanted that didn't have someone seeding. Other private trackers I frequent aren't as good about this.

I don't have experience in hosting space but I'll say you have too much text on the front page. Perhaps put some graphics there and concisely summarize your offerings. IMO, users tend to have very short attention span so showing them the big picture may help for converting them into beta users. Perhaps also move beta users signup form to the top. May be put something like "click to sign up for free" or "sign up for risk-free demo".

There's a simple solution to this:

Edit: Just saw your edit. This[0] may have been the problem you had with using :sql as the schema format. The counter-intuitive workaround is to output ruby in production. It seems weird, but doesn't hurt anything.

I would have to agree with you, choice of language does not give a 60x productivity gain.

However, it's not crazy to think that a really top notch engineer, who is an expert in Python, and who is operating on a much healthier and efficient team would give you a 60x improvement. Heck, 60x might be too low.

It's not a priori crazy to find a 60x productivity difference between two teams. What is the productivity improvement between one team who spends 1 year on a project and fails to deliver it, vs another team that delivers the project in 4 months? It's not 3x, because 3x better than nothing is still nothing. The second team is literally infinitely more productive.

I'm not saying they're wrong to want to keep their jobs, but, humans operate on such a huge scale and without a lot of foresight, and it's scary to think of how that will play out with 9 billion humans today and even more tomorrow.

That said, it's fair to say that Instagram (and Facebook and some others) have captured the casual photography sharing market and Flickr could probably have done better there. While it's true that sites like Smugmug cater even more toward serious use, I'm sure Flickr/Yahoo would have liked to have had a broader and more mainstream base.
There's a standard called hNews, created by Jonathan Malek (Associated Press), Stuart Myles (Associated Press), Martin Moore (Media Standards Trust), and Todd B. Martin (Associated Press), which addresses this:

hNews is a microformat for news content. hNews extends hAtom, introducing a number of fields that more completely describe a journalistic work. hNews also introduces another data format, rel-principles, a format that describes the journalistic principles upheld by the journalist or news organization that has published the news item. hNews will be one of several open standards.

http://microformats.org/wiki/hnews

I learned of it (yesterday) re-reading Readability's Article Publishing Guidelines:

https://readability.com/developers/guidelines

hNews is an XHTML microformat -- the tags are entity names and classes added to standard HTML entities.

Key among them are: hnews, hentry, source-org, dateline, geo, item-license, principles.

Other microformats, including hCard, can be used to identify people, companies, and organizations, similar to vCard properties. The elements will be familiar to those who've worked with address, Active Directory, or LDAP data: fn, n, nickname, org, email, tel, adr, and more.

http://microformats.org/wiki/hcard

An IDE that tied into these (or, possibly, other standards) could be useful.

You'd likely need some sort of natural-language processing in the copyediting or publishing process to apply this uniformly. Field reporters may work on a wide range of equipment and software (including pen-and-paper or simply voiced-in reports). And expecting reporters to incorporate tags into their copy is likely a stretch.
