Thanks (belatedly) for your comments.

The thing is, of course I know I screwed up. I don't need you or anyone else to tell me that. I already know it.

But that has nothing to do with my complaint: the top match for a Google search for "ubuntu add user" is a site that gives out poor quality information, doesn't improve that information as a result of user feedback, and has a community that is positively hostile to feedback. Yes, as you point out, there were also helpful comments in that thread. There were also several other people who had the same problem I did, and the site never did anything to improve its content.

Isn't it obvious that this was a lousy tutorial? Doesn't the author of a site like this have any responsibility to put out useful information? Does the fact that I screwed up make my feedback any less valuable? If you're writing tutorials, that's exactly the kind of feedback you ought to be looking for, so you can improve your tutorials.

Contrast it with Arch Linux's page on user management:

https://wiki.archlinux.org/index.php/Users_and_Groups#User_m...

> To add a new user, use the useradd command:

> # useradd -m -g [initial_group] -G [additional_groups] -s [login_shell] [username]

Here they do use the same useradd command that I was complaining about (probably because Arch doesn't include adduser by default?), but they give a complete example with all the options required, followed by an explanation of those options.

Now that's how you do it.

BTW, I was almost tempted to take offense when you said that I "should have gotten a computer-literate friend to help". Yeah, I guess I'm not very computer-literate. After all, I've only programmed in Algol-60, APL, assembler (Sigma 7, PDP-10, 6502, TI 9900, 8080, x86), AWK, Basic, Bliss, C, C++, COBOL, CoffeeScript, Forth, Fortran, Go, Java, JavaScript, Jovial, Lisp, Lua, Pascal, Perl, PL/I, PL/M, Python, Ruby, SIMPL, SQL, Trac, and a few other languages you wouldn't have heard of.

But we're all newbies at something, some of the time. In my case it was basic Linux user setup.

Maybe you even screwed something up once, as a result of somebody giving you bad information that you didn't thoroughly check out. (Not saying you did, just possible.) If that ever happened, which would be a better response from the source of that information: chewing you out thoroughly, or correcting the bad information?
I guess we've just had different experiences. I can say from experience, without a doubt, that I could not possibly pick out a warning among hundreds of compile/link commands.

Now, if dependencies were in order, and I'd just made a small change to a single file, and had previously built the project successfully, I'm sure I could probably catch a single warning. That's a lot of assumptions to work from. I prefer to let the build fail.
Spotify cannot be compared with traditional radio. Of course they are going to have to pay more. Spotify is essentially giving you access to an entire record store for free. On radio you get a limited number of select songs, you don't really get to choose what's played and the songs played get a lot more exposure which I'm sure is used to justify the lower fees.
To be fair, radio doesn't completely replace sales of singles and albums the way Pandora and Spotify do.

You can't compare on-demand services to radio.
It seems like the author got confused between "directed at" and "only seen/received by".
well, how did you market it? looks pretty neat to me.
There are so many things wrong with the comparison table it's difficult to trust the article. The Uno can run on 5v, not 7-12v; the Pi has shipped with 512MB of RAM for quite some time now, not 256MB; the Pi has 17 GPIOs, not 8. For example. I understand this is for beginners, but honestly…
Genuine question - What trackpad functionality do you use often on a Mac that you think saves your time compared to using the corresponding keyboard actions? I have used Mac for about 4 months in the last year as my primary machine and although the trackpad actions are quite flashy, I never found them useful.

I know Unity is universally hated, but I am fond of its keyboard support. I rarely have to use my mouse and I using keyboard instead of trackpad in those situations saves my time.
Yes, and as the fifth most popular site in the world, that is a pittance. They could be making billions with unobtrusive advertising. Given their traffic, the fact that they only raised $25 million last year means that nearly all of their users ignored their pleas for help. Further, when they do their begging, it is very obtrusive and disruptive to the user experience. Where alternative revenue models are available, begging shouldn't even be a consideration.
I expected to read about Peter Molyneux's problem of producing and selling games he dreams up around strange concepts, which I thought became so well known that it got an official name and put in Wikipedia.

But this was more interesting !
"make something, price it for more than it costs to manufacture, and sell it if you can... Pandora and Spotify are not selling goods; they are selling access"

except that's always what the record industry has been selling. at least Pandora and Spotify are honest about what they are. If i bought your vinyl record, do i actually own that or is really just a proxy for personal usage license? Can I play that record at my wedding, or in my office, or at a party with more than some arbitrary number of people?

Intellectual property is not a physical good. The recording industry has coasted along for the last 50 years or so on this strange phenomenon that allowed their IP to be sold as though it were a physical product while at the same time getting IP protections in addition to the revenue of a physical good, and they've made a ton of money doing so - more money than they ever should have. Now the gravy train is ending.

Getting paid per-play rather means that artists are finally seeing how people actually value their music. You can't use law to make your music more valuable. If you want to earn more then make more music, or go on tour, or put some effort into selling your music for soundtracks and the like. The rates spotify pays represent the actual value to the consumer - they aren't making a profit, and if spotify were any more than what it currently costs, i wouldn't pay for it. You might think your song is worth more than $10/mo in streaming royalties, but you might also be wrong.
I think that if I'm selling the the physical cd for $10 and the digital for $6.93, people are going to be apt to get the digital album only. Plus I have anecdotal data from several indie musician friends that when they release digitally, online physical sales effectively cease. I do know there exists the kind of super-supportive fan who will buy digitally and then also buy the physical cd as an expression of support, such as several of my best friends and family members, but in a magnitude sense, I think they're a negligible percentage. At any rate, I'm having trouble thinking of how my staged process will risk me missing out on any benefits of digital-leading-to-physical. I'll still release digitally; I'll just do it later.

As for piracy, it's a good question. Keep in mind I'm pretty small-potatoes. The question is, for a largely anonymous indie-artist, is the piracy risk of releasing physically-only greater than or less than the piracy risk of releasing digitally? My hypothesis is that it's less. But I'd have to find a way to measure availability and popularity of my tracks on pirate sites. If there's a way to measure a spike of demand, and ascertain that it's from people that would buy the digital tracks if they were available, then yeah, it would make sense to speed up the time frame of the digital release. But I don't really have any thoughts yet on how to measure that kind of thing.
All I see is lots of makeup. Might it more accurately be called a Korean Face Art Contest?

But really, if we're trying to compare physical beauty, wouldn't the contest require 0 modification of it? This would likely include banning makeup, any form of plastic surgery, unnatural hair modifications, and clothing that is overly supportive. Is there even such a thing? A cursory Google search suggests no. Even so called "natural beauty pageants" apparently permit caked on makeup, fake hair, fake teeth (not just orthodontics), etc. I don't see a point to these beauty contests, in that case. They say nothing about the person at all.
Is this the same Facebook that would take a handoff approach to Instagram?

The first comment is right, currently being the keyword.
If you are hoping to sell 300 copies, my guess is your best bet at building a career would be to give everything away free, setting up a website where anyone can download free mp3s if they give you their email address and zip code. With this info you can book tours, tell prospective labels "I had 10k downloads" etc.

Even if you were able to make $10 per cd, you're still in the hole. Maybe better to chalk the whole recording thing up to marketing expense and use it to give you better leverage in the future.
Perhaps you and I have a different definition of focus. Can you give me an example?
I find it horrifying how many developers are perfectly happy having warnings in their code.

On the projects I manage, warnings are unacceptable, and treated as errors. We will not release an update until it builds without warnings.
What is with your attitude? I understand the point. The point is not what I'm disputing. The problem is the moral judgment inherent in the delivery.

But you know what, OK. People don't want to discuss this here, it's not really on topic, deleted.
> "success of this totally depends on price"

Maybe partially but the real success lies in designing something like this that can be worn without the user looking like a huge nerd. Otherwise it will never hit the mainstream. I mean, I even know many tech early adopters who think its a cool experience but would never use it in public the way it looks now.
The Problem With How We Treat Bipolar Disorder
Ah, you'll appreciate this if you haven't seen it already: http://www.theverge.com/2013/3/4/4054634/musics-pay-what-you...
I'm attempting to answer your question, not advocate for a moral truth.

A male invests so little in procreation relative to a female, that it's easy to imagine an advantage conferred to massive promiscuity among males. (anything that gives a higher percentage chance to reproduce would tend to beneficially differentially propagate a male-promiscuous geneticly driven behavior, in a way that it would not be selected for among females, since they are generally limited in procreation capacity per unit time in a way that males are not. Elements of this are seen in the animal kingdom, but I don't know whether it's generally accepted "fact" or not. If it is, and it's programmed as part of mammalian maleness, it's reasonable to assume that humans would also exhibit it naturally, and not just via locker room social pressure or other "buried" influences which might also be present.)
One would think a company that has success in mind would have the brains/motivation to actually learn about the culture they're setting up in. [A pattern could emerge if one were to draw parallels to wars in far-away Asian countries, though.]

They can't have that good of a grasp of Swedish culture if they thought this would work. I'm struggling to find a hypothetical country in Europe where "obnoxious American" is the preferred type of American.
Yes.

According to them, they agreed to be acquired to gain resources from Facebook. This reminds me of what Youtube did with Google, and many other acquires. I expect Parse to become better and better.
Part of the problem with eigenfaces is that they are really sensitive to variations in pose, which, as the author notes, are present in this data set. The article doesn't actually compare the variability among these faces to the variability among a control population of Korean faces, so I don't know to interpret the results anyway, but my guess just by looking at the eigenfaces is that they are capturing pose variation in addition to variation in facial structure.

Check out the results page on the Labeled Faces in the Wild site for some better algorithms that are more robust to changes in pose, along with their performance on a sample data set: http://vis-www.cs.umass.edu/lfw/results.html. Eigenfaces are the worst algorithm tested. Amazon Mechanical Turk is better than all of the algorithms, even if you show only the face itself OR show only the remainder of the photograph that doesn't include the face.
Commonly called fair division or cake-cutting. There are "fair" algorithms for the general n-person case:

if spotify were any more than what it currently costs, i wouldn't pay for it

That doesn't mean much, without the context of what you would do instead. Listen to CDs? Stop purchasing music? Torrent it?
Or alternately, to have built them in Area 51.
> The only downside I can think of is someone accidentally commits a single-line, commented out variable declaration.

Yeah, that's the sort of thing I was thinking of. Or empty method implementations, or dummy return values, or whatever.

I guess my point is just that if it's more convenient to do something else before fixing an issue, then it's better to have a warning reminding you to fix it than to not. And if you're not going to circumvent the error, you're probably not going to ignore the warnings either.

Reading your other comment, you mentioned working with make. The advantage I mentioned only really applies in IDEs.
Ask HN: Solr Hosting in the cloud
Hi HN-ers,

I need to host Solr in the cloud, I am looking for a host other than AWS. Any suggestions or recommendations?
Yes, but: I can't remember the last time u wrote a comes reflex. I've since learned to use an xpath parser, for example.
I think that's why the problem is so interesting and the answer so telling about the human brain. The way I picture it is that if you closed your eyes and held a ball, you would picture a sphere... but it is because you have in internalized image of a sphere. If you had never seen a sphere, you probably wouldn't be able to imagine one... even if you could feel all it's dimensions. Your mental 'canvas' is not only lacking paints... you don't even have a brush.
In a small market the MVP will be more salable than in a larger market; regardless of the complexity of the MVP. That's the OP's point.

Any other reason you think this person has no understanding of markets? Because so far you've got nothing.
You'd think, because it all boils down to coordinates, right? Or at least relative coordinates. Apparently not. It's more like pattern matching, where the patterns are much more abstract than a coordinate system, where the connection between felt and seen patterns has to be learned, and the translation of either into "coordinates" has to be consciously worked at. I don't really know, not being anything like a neuroscientist.

I'm also reminded of the way babies are born seeing upside down, and learn naturally to invert their vision. Apparently if one wears glasses that invert their vision, it eventually flips back. Is that a built-in transformation, or is it deduced from first principles, just to make a simpler mapping between seen data and other data, e.g., to more simply reconcile feeling your hand move one direction and watching it move in another? If from first principles, what else is it doing? And we know the brain adds stuff to the picture before it's presented to the conscious mind, too.
You're not handing them money jackass, you're loaning it to them, and you're being very well paid for it - ROI waaay above market rate, if you realize that market rate means the junk bond rate.

"Handing" it to them would be if you didn't get equity or anything else in return.
You probably can. You can't construct a spatial model of something by seeing it unless you've already gotten used to the various effects (perspective, parallax, etc) and how they represent space, though.

Or, at least, that's my totally untrained opinion.
Great product, I loved it but I'd be in great trouble trying to monetize, hope you'll nail it.
How did Instagram change since the purchase by Facebook? (honest question, I don't use Instagram at all)
curl ifconfig.me
This is exactly what I was looking for. I was previously using http://automation.whatismyip.com/n09230945.asp, but the author is no longer making it available for free.
Small markets don't attract large well funded competitors (because their investors don't let them target them or redirect them to larger markets) allowing you to develop and refine an offering you can then aim at larger adjacent markets/segments. One good book that outlines the trade-offs is "The Origin and Evolution of New Business" by Amar Bhide that did a rigorous analysis of the Inc 500 companies.
Downvoted for being an ass.

I like `curl icanhazip.com` because it's cuter.
Yeah, thanks a lot Radiohead and NIN.
They had < 10k plays in 3 months. That's not album sales nor requests; that's just number of times their music played via a bot-stream. That's so low it's practically irrelevant.

They sound like someone who started a blog a decade ago, stopped after a few years, only updated it twice since, and are upset their AdWords income is low.
Forgive me, but what's so exciting about this?
curlmyip.com is usually my go to.
Follow through my Medium profile, I'm most active on Twitter. DM me if you still want to reply
The artist's share of income from record sales and radio play has been next to nothing throughout the history of the record industry. Any experienced artist will tell you the real money comes from live shows and merch (which can still be pressed discs). This is why file-sharing only hurts the labels, not the artists. The artists actually get more exposure without losing much royalty income from the illegal downloads, which actually help promote the band and draw bigger live crowds to gigs where they can actually make some money.
I got $3,000 USD from Facebook :)
You mean like the time he wrote a huge expose on Obama's sellout to Wall Street that confused two different James Rubins, claiming that one of them (we're now not sure which one) helped "pick Obama's economic team", and claimed TARP could cost twenty three trillion dollars?

ping `curl ip.nux.ro` :P
It also supports IPv6. whatismyip.akamai.com is IPv4 only.
Most "what is my IP?" services either return it in hard-to-parse format, or they block curl.
Live performances will always be the profit center.

I am tired of hearing this mantra repeated as fact. There are significant up-front costs to live performance that are not at all sure of being recouped. If you make some sort of niche music whose audience is highly dispersed, then you might not be able to get enough people together in one place to support a tour or more than one or two performances a year.

Have you ever worked in a band or as a producer or some similar role?
Are there many people who would not buy a CD at all? I usually check amazon / itunes if it's available for digital download if I hear an artist I like on pandora.
That should be easy for them to do. They have geo ip info, also know your tastes. Say you listen to Mumford n sons, but lumineers is coming to town, you might enjoy that show.
I'd compare it to disabling the snooze button.
This is hilarious, this dude needs to get outside and enjoy the sun more.
So then you presumably believe that Matt Inman at The Oatmeal was wrong to be upset at Funnyjunk for appropriating his comics; after all, he had no right to claim them as his own property.

And, of course, what you're saying about the market valuing music is that the market values music at zero; the price of music on streaming services is simply the premium people pay over free pirated tracks in order to have a nice user interface.
I always thought that the benefit of services like Spotify and Pandora was to get a band's music to people that wouldn't ordinarily be exposed to it. This in turn would prompt listeners to go buy the band's music on iTunes or Amazon.

Good music is really hard to find. I search around iTunes all the time and come up with nothing. So ANYTIME I hear a song that I like I buy it within the same day (usually the whole album).

For bands that aren't seeing this sort of conversion on sites like Spotify and Pandora, this might tell you something about the demand for your brand of music.
How to Sell a Chicken Suit
Running a bubble of investment capital without breaking even is a broken model. Inflating a company to biggest possible size is a broken model too (the company does only become less effective with size).
Fast Weight Loss Through High Intense Type Exercise and a Strong Mindset
"Leptin resistance" is when a persons "feeling satisfied in between meals becomes more difficult," and trying to lose fat becomes extremely difficult. What is very interesting about this hormone is that it is reproduced in the fat cells. But yet the heavier you are the less adiponectin you are producing. Adversely affecting the amount of adiponectin in your fat cells. Just two functions of adiponectin are to assists in lowering glucose and increased activity in cells to burn fat for energy helping to lose fat successfully. This "fatburner" hormone is pertinent to diabetes, kidney disease, weight loss, and inflammation.
It seems like a Nyquist-rate of slices would do the trick, but is probably not the lower bound on number of slices.
Small acts make fuck-all touring. Members of bands who have put out multiple records on well-known indie labels routinely make $50-100 for a single show. Touring revenue is great if you're one of a few big ticket acts; it is a lie we tell ourselves to justify not paying for albums from almost all of the rest of them.
> I do know there exists the kind of super-supportive fan who will buy digitally and then also buy the physical cd as an expression of support ... I think they're a negligible percentage.

I agree, I think that expecting fans to buy your album twice is unrealistic. But there is a middle ground in the approach that mp3.com pioneered (and was mortally wounded in court for) -- sell the physical disc and include an immediately available digital download as part of the package.

I expect that you could put both options up on your website - $10 for CD only or $13 for combo CD+MP3 and you'd probably sell just as many of the combo as you would have sold of just CDs if that were the only choice. There's been a few studies of the psychology of pricing and marketing on HN that would probably help inform your decision.
Not in any measurable business sense. As a means to explain public dissonance regarding this current market, then yes.
Until, you know ... we change our mind.
I have done exactly the same thing you have - I thought that was obvious in the way I phrased it. Just declare "it's this" and moved on. You've provided nothing of substance in the way of rebuttal at all, just a defensive "you don't know about me", and even now, you continue to avoid supporting your statements.

And 'show us several examples'? Really? So I get to go and do more work, only for you to hand-wave them away with "yeah, but those are just edge-cases". How does one prove anything is not an 'edge case' with a couple of examples?

As for rudeness and bigotry, it's pretty much what I thought you were being by just dismissing my statement as 'edge cases' when they're not. 'Feminism is 1-dimensional' is as bigoted as anything I've said. And despite you being pride-wounded at how I assumed your background (which you still haven't fronted up with), you say I've 'never seen this literature', assuming my background. And now, interestingly, not even allowing for the existence of your 'edge cases', because that literature now 'doesn't exist'.
