^^^Nice way to seize the moment.
Interesting website concept. Just a suggestion for the homepage: since the top header is so tall, how about moving the play song links from the bottom of each song-artwork to be a universal play symbol (arrow) overtop the artwork, maybe increasing from translucent to full opacity upon hovering, noting contrast issues with relevant artwork. NOTE: at my 1080p pc monitor and font size settings I dont even see the song title 'above the screen's fold', so you may even want to think about that as well, maybe the same solution as the playbutton using overlay and opacity settings. It is a cool header bg though so dont mess with that, except maybe moving the search box onto it since having it below eats vertical space from the song listings as well.

Last point/question: I'm assuming the $1600 headphone giveaway is for the musicians, not listeners. Good growth tactic but maybe make it more clear OR offer something to listeners as well. I don't know much about the song development process market but maybe implement or communicate something about whats expected/gained from listeners for improving the music (assuming you actually want to help musicians rather than eat their souls lol)

EDIT: minor ui change to song pages: move everything on the separate login page as an embedded form on song pages (above the comments). No need to ask me to click and hope you've integrated with my favorite 3rd party.

EDIT2; Startup based advice: you might want to look into the business model of that site that advertised on thepiratebay using popups autoplaying (fairly decent) music videos of indie artists competing for a prize. Cant remember the name or find it on google, maybe it shutdown? Had a one wordish name derivied from video, definitely started with a V
That's an implementation detail and should be open to change without breaking things.
A few things many coders don't worry about enough when it comes to testing:

1: Most test code is of lower quality than production code.

2: Tests often contain assumptions and those assumptions are usually not checked against any external reference. Whatever is assumed within a test is de facto law. Consider mocks, what ensures that mocks have the same behavior as the objects or services they're mocking? Mostly it's just an untested assumption.

3: By far one of the biggest class of errors in coding is omission. And there tests barely protect you at all. If you forget to implement a particular feature/aspect of code chances are that you're going to forget to implement a test for it as well. The way to solve these problems is with thorough code review and integration/beta testing.

Ultimately you get into a "who tests the testers?" problem. Which, most of the time, is answered with the resounding noise of crickets. Tests need code review. Tests need owners. Tests need to be challenged. Tests need justifications. A lot of the critical rigor surrounding testing is eroded by common practices which encourage a distinct lack of rigor around test writing (TDD I'm looking at you). Tests aren't magic they're just code, they'll tell you what you ask but if you're not asking the right questions the result is just GIGO.

Too many devs think that unit tests are cruise control for quality. They're not. Doing testing right should be just as rigorous and just as difficult as implementing features.
The Paidez thing is embarassing - we re-branded really fast and couldn't move all the services over before we launched. We're working on it now, but it sucks.

What do you mean about the HTTPS? We load ALL our content via SSL, do you mean knoxpayments.com isn't automatically loaded with SSL? There's nothing secure on it I guess, but even that should be for consistency.

Our payment process requires SSL end to end encryption, but are you suggesting that having Knox Payments not load with SSL by default it looks bad?

If I've missed something more important please tell me - if there's something (other than the atrocious switching of URLs) that is making you nervous, I NEED to fix it!
It's a bit dated now, but in March 2012, Dr. Sadoway gave a TED talk about how these batteries work:

Web without CSS and JavaScript would be a quite boring place.

But hey, at least with GSS there is no need to rearrange your content in weird ways to accommodate to CSS layouts. So what you'd get is just the plain, semantic HTML.
Nope! Conversions are pretty good, same abandonment as CC's right now, and it's rising as we get our UX better. People hate inputting their CC information, and when they've heard of Knox at least 1 time before, they're way more likely to convert than using a CC. However, first time users are about the same conversion as CC's in our betas.
An interesting debate: "Jim Coplien and Bob Martin debate TDD": http://www.youtube.com/watch?v=KtHQGs3zFAM
Some things are really hard on users when they break. Kernels are especially hard, because only one can run on a (non-virtualized) system at a time. System libcs are pretty hard, ditto init systems and some other deep infrastructure.

Language interpreters can be annoying, but not to the same degree. It is quite easy to run multiple Python versions on one system. It's also relatively easy to find and fix the broken Python code in a case like this -- it's always sitting there on your drive, open for inspection. And it's not black magic -- anyone with a little programming experience, even if it's not in Python, can easily understand the issue and the fix, and make the appropriate change.

Nuance matters, and unlike a boolean, principles are not always binary choices.
Its not the admin. Michel Bauwins runs the P2P foundation. He is busy advising the president of Ecuador on their economy. Not a good suspect for juvenile fakery, imho.
As you should be! We're working really hard on educating our users at the point of purchase, but we do a meh job right now. However, users who are able to understand that we don't store any of your information convert at a very high rate.
Wrong time(), you want datetime.time().

time.time() returns the seconds elapsed since the epoch.
Reporters misquote and put their personal or editorial spin on even the most trivial stuff. (Speaking from personal experience.)
Heh, leashes - yes!

And now give us the link to your ambitious sounding project.
Hypocrisy is behaving in a manner inconsistent with one's principles. One can have a principle that people shouldn't do anything that could assist something they consider evil, but if they have a less strict standard, doing so is not "the literal dictionary definition of hypocrisy".
It's not perfect but I'd like to point out that it was born in 2000 and still works fine today 13 years later. I think all the sample code I wrote is still in the PayPal docs somewhere.

The most painful PayPal integrations for me were the SOAP ones.
>Unfortunately, that proves nothing.

Linking Dorian to Bitcoin at any time proves everything, proves Dorian = Satoshi. If Dorian paid for crepe in July 2011 with Bitcoin, Dorian is lying and Dorian = Satoshi. There was a large Bitcoin Conference in New York at that time, giving good reason to be there. The retailer said she recognized Dorian as the customer. He didn't want his picture taken or name recorded. Good odds to me it was him.

And "large volume" = 432,000 coins.
> That is not so - in fact, there are many different governments and many different ways to store money, which allows to hedge the risks.

For the omnipresent omnipotent investor, that might be true , but probably is not true even for that investor -- e.g. the US government can and does have a wealth tax in the form of inflation, that applies to every single asset class anywhere in the world, enforced through FATCA/FBAR; You have no legal way to protect your assets against inflation+taxation).

If you're in Cyprus, and you need money usable in Cyprus, you are dependent on a functional Cypriot government, one that did not employ capital controls (But they did...)

Furthermore, a lot of people here are unaware, but for at least 3 months, there was more than one currency called "Euro": The Greek Euro, and the non-greek Euro. Banks in Germany would NOT accept greek Euro, or remit non-greeo Euro to a greek bank without collateral or other guarantees. All fiat money is fungible.

>> It's not. There's a point when failing government resorts to actions which go beyond regular taxation -

Your statement is ironic. Who gets to define what "regular taxation" is? The US had, at times, 80% taxation. Is that regular? The US government has been running a much higher than reported inflation for years. Is that regular?

Let's not forget that Newsweek has changed hands recently and has published at least one provably false story since then. They are relaunching their print version tomorrow, and even if they are wrong everyone is talking about them. There isn't any compelling evidence provided in the article just circumstantial.
All Cities Are Not Created Unequal
It's almost always possible to update APIs without breaking backwards-compatibility.
There are multiple, but this one seems to be the touted one:

No he did not. Unless you are 5 years old "Duh, I knew that" is not the same thing as admitting fault:

"Duh, it's fake. Obviously, it's possible to set your system clock back. I was so intrigued I wasn't thinking clearly, even after I pointed this very "attack" out during the Ed Snowden GPG affair. Sorry folks, maybe if it were timestamped in the blockchain."

He played it off and says the real answer is obvious. Then he provides an excuse for not recognizing this obvious truth. Finally to make matters super strange he informs us (w/o evidence) that he was the one that pointed this "attack" out to us during the Snowden affair.
Important note, I believe this doesn't include marketplaces.

What are the terms of your contract with them? Is it allowed? When I built stuff for BigCos I was under NDA so will have to go back and ask permission to post the work.

I am reading Ben Horowitz's book, and it is interesting to me that they made an investment into the same field as LoudCloud 15 years ago. Maybe they were just before their time.
In general, it's not about what distro you install per se, it's about what processes you have running.

Your best bet is to start with a more minimal distro like Crunchbang or Debian and only install what you need. Then use something like Powertop or whatever the current hotness is, to analyze per-process power usage.
Very thin:

"Sadoway, who is also the John F. Elliott professor
of materials chemistry at Massachusetts Institute of
Technology, wouldn’t say what goes into liquid-metal
batteries."

Here's a description from an earlier article -- same idea with different materials:

"After hitting upon the idea of the liquid-metal
battery, ­Sadoway searched for the perfect electrodes:
he ended up choosing magnesium and antimony because
they are cheap and separate naturally when in liquid
form, the lighter magnesium rising to the top. A
liquid-salt electrolyte rests between the magnesium
and antimony electrodes, creating a cell with three
layers."

http://www.technologyreview.com/featuredstory/511081/am

So it's a chemical battery where the electrodes are liquids. (FWIW: Magnesium melts at 650 °C).
Bureaucracy and politics are a bitch. Lately there's been the JWST overruns which have been screwing over a lot of the NASA space science budget (it's probably worth it but damn it's inconvenient).

But things are looking up and the biggest change is in launch costs. SpaceX thinks they'll be able to operate a reusable Falcon 9 for $5-7 million per launch. That seems crazy but if you look at the math it's pretty sound. That sort of change, with a first generation reusable vehicle even, will revolutionize spaceflight, especially unmanned space science missions. It'll make it possible to fund small space science missions using crowd funding. It'll open up interplanetary science missions to a huge number of colleges, universities and research organizations. A lot of the cost of space missions comes about due to the high cost of launch carrying through to every aspect of the mission (if the launch costs $200 million then you can't just launch a $1 million spacecraft, that's a waste, you also need to have a very high (say >90%) chance of mission success so you engineer accordingly).

Within the next few decades there will be fleets upon fleets of science spacecraft looking at the stars and roaming about the Solar System.
Poor man's Spritz
I read about Spritz today and was dissapointed to realize that it isn't still available, so I hacked a very basic version of it just to see how it feels.
Wait, how is it relevant?
I really appreciate your comment. I feel really dumb for not knowing that. I always assumed the worst. Want to reboot and instance to just check the init process?... can't do that on Amazon. I'll pick a different platform. I was way off base.

That being said, do they dump your instance if they reboot the physical server? I was under the impression that "Oh we want to upgrade they hypervisor kernel, your instance is toast", was fairgame/default on Amazon.
Braintree isn't a bad choice, not the best but better than most. Their documentation and needs for more complex stratiges for domain logic is lacking. Stripe has one of the best documentations I've seen as far as payment gateways go and how it can fulfill most business needs. As far as MVP products go I grade each api on documentation and flexibility. 1. Stripe, 2. Braintree, 3. Custom gatwate solutions such as shopifies gem. Im sure there are many more solutions but as a developer without a huge background in payment processing solutions this is my assessment.
Mistaken identity is likely, considering how eyewitness accounts are actually quite unreliable.
Not really sure why you care about that. It doesn’t pretend to be accurate so it doesn’t really matter.
Ask HN: How does a non-senior dev find tiny startups to join?
I am a competent, middle-level developer with 2 heavy years of ruby/js/general startup language and frameworks knowledge and I really want to find a tiny startup to join where I can have a tangible impact on the company.

Trouble is that every ad/posting I've seen for smaller startups are always looking for senior devs. I don't trust going through a recruiter, because their payday comes from any placement, not for the placement I specifically want (and I have had a bad experience with recruiters).

Is there any value for a mid-level developer outside the bigger companies?

I bought two speed reading apps earlier this week - didn't realize yours did epubs. More important than increased letter sizes, I think, is the redicle. I hope you add it to your app.
It might be less than ideal, but I cloned my profile in iTerm and set it to use lighter colors (Solarized Light) and just switch to it when I kick on darkroom. You should be able to map this profile change to a keyboard shortcut, depending on what you're using, to make the switch a little easier.

Solarized has a toggle plugin you might be able to use/modify so that you can switch themes easily.

No Pooled Bandwidth
Networking and Route, as well as capacity need some work. Linode is much better in this regards.
No Custom Kernels
IPs Problem.
Still no deploy to different physical hardware by default.
No Private Networking on most of its DC.

And possibly many other small things i didn't mention. To me most of those are deal breaker. And my problems with them is that are not fixing or improving these problem quickly enough.

While Linode's SSD are quickly approaching, and has none of those drawbacks.
A little bit more info and clarification here [1].

What I find so clever is that the containment is about as simple as a "hot bucket", hot enough to keep the anode, electrolyte and cathode always molten. The are materials chosen so that their different densities keep them separated physically in operation. No membranes, easy scalability.

A good way to fund NASA and the NSF would be to create a "technology trust fund" funded by a small tax on the sale of gadgets and software.

This would operate like the National Highway Trust Fund, which helps maintain the interstate highway system and is funded through a fuel tax.

Because the money comes from a tax dedicated to the purpose, congress doesn't get to change the funding formula every time they pass a budget. While a future congress could dissolve the fund, that's a lot bigger step than adding or deleting appropriations during the budgetary hog-trading process.
Yes and no. The town I live in has multiple billionaires living in it, and is adjacent to two with even more. I've visited two houses owned by such folks and their answer is what you'd expect: private security guards. Large, well-armed, and very unfriendly until they've verified via radio you're actually supposed to be there.

The key is, though, and maybe this is what you're referring to, that these folks don't store wealth on their home PCs. So their threat model is a little different.

I'm sure HN readers who follow Bitcoin more closely than I do could think of a better system, but presumably the real Satoshi could hire lawyers to set up a company or trust to hold his bitcoins, sell them over time, and store the proceeds in a more traditional manner. Not especially difficult. And, assuming taxes are paid, it may even be possible to remain anonymous.

A staggeringly progressive tax - say 99% on income over $1M/y - might adjust the priorities of those who are winnning, since there's no more financial gains available. Maybe then some of them would turn to other interesting problems like making things better for everyone.

Get permission, or get it worked into the contract with them.

Stay safe: Large corporations, such as Fortune 500 companies, often have subsidiaries, branches, or otherwise incorporated offices all over the world, and also in their home country. Ensure that the legal entity you work with has sufficient wording in the contract that you can claim to work with the parent entity too (the Fortune 500 recognised name).

But in the end, surely it is about your relationship with someone you're claiming a client (and I'm assuming this is the case, having their logo on your website, and that you're including the logo to convert other largish clients). If basic due diligence if performed by a prospective client and you don't receive a favourable reference (or worse, a denial of relationship), it will kill a conversion either at the outset of later (and later could be worse - legal charges of misrepresentation or worse).

Stick with names that you have an auditable relationship with, that include positive anecdotes, and can be relied upon to confirm a working relationship.
Two things: please don't do this without explicit permission from an appropriately authorized employee (probably different from your contact). Also, personally, every time I see this my main reaction is "OK, one small team used a credit card to buy this service, its not as if all xx,xxx employees of $bigcorp are relying on the platform for daily LOB activity"

If I were Satoshi (Dorian) Nakamoto and I wanted people to leave me alone, I might post as Satoshi and tell people I'm not Dorian.

If I'm Satoshi Nakamoto and I'm not Dorian, I might post as Satoshi to try to get people to leave Dorian alone. But that's a pretty feeble attempt. If he cared enough to get people to leave Dorian alone, you'd think he'd come up with something that provided a bit more proof. Otherwise, why bother breaking silence?
That would be an understatement.
Except there's no evidence linking Dorian to that July 2011 crepe. Is there? Someone said "I dunno, he looks kinda familiar?" That's it?

Hah, I caught it right away and chuckled, especially since it's got the timestamp faked back to 2001.
Ugh.. time, durations and location is enough to make anyone's head spin. Nice to see how important something so overlooked in many languages is addressed. I haven't personally had the opportunity to play with go but I like what I see.
Oh, I thought they cost significantly more, not bad (much cheaper than an Abrahms)
Dorian is claiming he never heard about Bitcoin until a few weeks ago so if he was using them in 2011, then he is obviously Satoshi

An audio recording is evidence. What you quoted back to me is the possibly flawed recollection of a reporter who's in the unenviable position of defending a very high-profile cover story used to relaunch a national magazine. That reporter is no longer a disinterested observer. The AP, to a first approximation, is.
your department sounds pretty awesome. I've never seen anything like that. Unfortunately I don't have the option of choosing our clients. I am but a humble developer for an 8a contractor.

Possible idea: Display all user-added activities by popularity so that someone thinking about hosting an event can get an idea of whether there is already an interested "waiting list"?
Excellent, congratulations to the creator. This looks like a good js communication foundation for practically anything.
