Yes I checked them myself. I clicked each course, and saw if all the notes, quizzes, and exams with solutions were there. Around 30% were missing. So I do not define that as amazing. Anything from coursera, MIT Opencourseware is usually good. Also, there are many resource compilations posted to HN that can be searched via hnsearch.com

I'm not sure why you had to ask me if I am sure, when you could have easily corroborated or discredited my statement by checking yourself. And if you did, why didn't you post your own conclusion?
I'm sure this works for things which you might buy having only see the website (and maybe a few screenshots) but beyond a certain level of cost/complexity you actually need to have some real software for them to try before they'll pay.

I never been on such a website, but doesn't this make people angry? Or is the trick to do it also withe fake product and company name, so that you know it would work, but noone can hate you afterwards for lie to him?

Kickstarter seems like a better approach, since everyone KNOWS there is no product to buy.
I'm not sure how it would happen, but if you could get miners to perform arbitrary computation for you, as a consequence of processing zerocoin transactions, then people might decide to abuse that and generate tons of otherwise unnecessary transactions.
That's the date I use on every site that asks for it (it's not my birthday). I have the vague hope it will eventually break something somewhere.
This doesn't make sense. If Google really wanted a copy of your texts and contacts, why would they ever need a Google Search update to obtain it?
Huh? How would you determine if something was randomly chosen based on a single selection? Given all the colors available, is #FF4A00 not a possible selection in your function?

Regardless, this is incredible nitpicking. "Pick one randomly" from the human brain obviously specifies a bad PRNG. Who cares?

"Would they not try to claim that using Zerocoin is, in effect, making you an independent exchange?"

Might be difficult, there's no market there. One Zerocoin is one Bitcoin in value by definition. It's not an exchange to convert dollars into cents, so it would be hard to argue this.

Dynamic-mode Groovy is as slow as other dynamic languages. The recently added static-compilation mode for Groovy still regularly spews up bugs, perhaps because it was written by a single programmer with little beta testing whereas Scala and Java have many high-pedigree developers behind them, and heaps of documentation and testing.
I'm more interested in: "An administrator is a person engaged as a business in issuing (putting into circulation) a virtual currency, and who has the authority to redeem (to withdraw from circulation) such virtual currency."

If you participate in the Zerocoin network, you can therefore issue Zerocoins (in exchange of bitcoins), and redeem Zerocoins for bitcoins.

Preferences and commandline options can be used to specify preferred resolution, though HD can be really nice.

.int is already in existence: http://www.un.int/. US jurisdiction over .com is problematic because the US government routinely seizes .com domain names of websites that are legal in other countries. This doesn't affect me much as a law abiding US citizen, but it's a huge problem for 100% locally legal sites outside the US that want to have an international name.

Somalia is often trotted out as some kind of pseudo-argument against anarchism, as if it were an example of what would happen without a government. I can see at least a couple of problems with that:

- Somalia has a government, regadless of how "effective" it is, and that alone makes it an invalid comparison.

- The absence of government means the absence of coercion, and that everything would be based on voluntary trade. It does not automatically follow that every place without a government would be a hellish shithole. That soup requires other ingredients besides "no government-controlled police force".

> You seem confused. Arguing against a strawman involves describing an opponent's argument falsely and then attacking it.

- I pointed out that the existence of Government is a problem.

- You implied I was advocating emulating Somalia (originally calling it "governmentless", but now covering your ass by adding "effective").

"Strawman" seems appropriate. Who was the idiot again?

There can be a very real issue if HN accounts have an age or birthdate associated with them which indicate that the user is under 13. In that situation where knowledge of age is in the hands of the website operator, the FTC has taken notice, and action. See Path's recent FTC COPPA ruling as an example.

So, if HN internally keeps a reference from votes in the under-10 category of this poll to the accounts they came from, and if any of those people are under 13, there may be cause for real concern re: COPPA.

There are sort of 3 ways to approach this safely...
1. don't ask, don't tell (eg: Google's main search page)
2. ask, and reject (eg: Facebook account signup)
3. ask, accept, and get consent (eg: some child focused sites)

HN is pretty clearly not a child-oriented website, but if there is concrete knowledge of age, COPPA can apply.
That, unfortunately, only works for Flash and not HTML5. But maybe I should just use a better browser and then magically this wouldn’t be an issue or something.

"The ACLU has long been strongly supportive of COPPA. It is an important first step on the road to universal baseline privacy protections that ensure that every American—young and old—has meaningful control over their personal information online. (...) The ACLU protects privacy and free speech simultaneously, and the two interests are rarely at cross-purposes. Right now, COPPA is a great law and it does both effectively."

To be fair, bitcoin has a number of interesting technical promises. The economics of bitcoin are... probably going to be bad, for many reasons.

But some decentralized digital coin in some form seems like a good idea. The concept of a transaction log that tracks your money from start to finish is also interesting.

Bitcoin will remain a pyramid scheme due to its deflationary nature. But maybe a future coin can be invented that solves the problems with bitcoin?

Ask HN: Help to get us feedback (v2)
Hello HN,

We are working on a project management webapp called Route. We already asked you for feedback some time ago, but at that time only the most curious hackers gave Route a try, others were stopped by a tedious registration form. So we simply got rid of it. Also we introduced a nice walkthrough to show the basics of Route.

So, check it out and tell us what you think!

I thought this had one nice enhancement, which was a continuous line indicating whether a not remained the same... but for some reason even that's not true.

In the first measure of the treble clef, the line coming off the middle note of the final group dips down, even though the note doesn't change.

Sometimes it's hard to see if a note changes, and a dipping line or straight line would be a nice cue. I don't know why this one dips when the note stays the same.

Electric Velomobiles: fast, comfortable, and more efficient than cars
Pretty much everything you listed has been a problem with those products from the beginning. My point is, Google hasn't ruined everything like the OP wants to claim, and there's no massive backlash, even for Google+. It's really a shame that even on a site like HN, a completely exaggerated and emotionally driven response that only has a shred of truth can get so many upvotes.
The "above" is supposed to stand for the A note?

I didn't get that from any part of this. How can such a basic point be so poorly (or not explained)?

Using icons that translate to English words to stand for note letters is a terrible idea.
The post you replied to (with the "GooGoo Fanboy" term) was overly vociferous.

But that's when it's most important to avoid words like 'fanboy' because otherwise discussion dies. People probably thought you had a good point, but you lose that when you use words like 'googoo fanboy'. And that'll do nothing to sway the person you're replying to. If anything it'll just entrench them even more.
Another reminder that Life is very short.

I think this is a really important post, and I hope the suggestions are implemented. This will give Promises in JS a clean and simple API.

The current proposed API is full of corner cases, justified on the basis that providing a single method, `then`, is simple. Unfortunately this is too simple, hence the corner cases.

Unfortunately it seems the people in charge of the promise spec are not open to change, or even to rational argumentation. If you want to see some really pathetic behavior read this thread: https://github.com/promises-aplus/promises-spec/issues/94
Excellent initiative. I'll check it. I hope you will also provide some general talks on strategies we could use to test this as early as possible.

Sometime it just need a few more optimization iterations. Considering the Facebook example and prior art, this must be really frustrating for those who missed the gold pot.
After the first passive indicator (mail, IM, issue tracker), I much prefer phone/face to face over written communication - faster and higher bandwidth.

As for interruptions - if somebody else is stuck, and a quick answer from you will let them continue, then you'll be less productive, but the overall productivity may be higher.

Your Guide to Successful Auto Transport and Car Shipping
I read yesterday about a cloud hashing service. You paid $150 in BTC for a 1G/Hash slice of a 1T/Hash machine for a year. Or paid $250 (in BTC again) of ever. With an expect return of 5 BTC per year and 6 BTC per year respectively. The site offered 6000 slots available and the machine would be up by June.

My problem with that is it seems just like a scam. They are making $900,000 up front in an untraceable currency. They are proposing that you'll get an annual return of $720 at yesterdays rates.

My gut tells me that if its sounds too good to be true it generally is.

Gold has value in that it can be made into something, bitcoins have value only because of the perceived value. How is bitcoin different from the ponzi membership badge I have? What is going to make bitcoin still worth something in 10 years time, as in what's holding its value up other than perception?
Yes please! I'd like to subscribe.
Why do intelligent HNers spread this constant FUD that "governments will make Bitcoin illegal"? Seriously WTF?

Fact: there are plenty of currency/commodity markets (1) that the US government does not control and (2) that are used sometimes for illegal activities such as laundering, and yet the US government is perfectly fine with these markets existing and being legal because they are necessary for a healthy economy and are mostly used for legal activity. Two examples: gold (obviously the US does not "control" worldwide gold trades, and yet gold is often used for laundering), and foreign currencies (perfectly legal to hold and trade in the US, even those from countries with strained relationships with the US such as the Iranian rial, Burmese kyat, etc).

Supporting my viewpoint, the US Treasury Department, through FinCEN, has recently tacitly approved Bitcoin: http://www.businessinsider.com/is-bitcoin-legal-2013-4 It is obviously in the US' interest to let the Bitcoin economy grow, and merely get revenues from it by taxing trades, capital gains, etc.

This is not the first time I explain all this.

The SpreadRank: a visualized algorithm
The velocity that information propagates through Twitter is fascinating. But by only looking at your timeline, it is not easy to see this. MFG Labs has created WDMTG (Where Does My Tweet Go?) to help you understand how tweets spread.
PG, have you considered that many (though granted not all) of the "junk" answers may due to the hacker mentality, people asking themselves questions like "what if I choose more than one option, will it let me?", "what if I 'accidentally' select the wrong answer, can I undo it?", "What if too many people give implausible answers, can it be corrected for or will the poll be junked?" and so on. Hackers - tinkers and the curious.

Working in survey based stats all day, I can tell you that the easiest junk answers to filter out are the ones you're seeing at the moment. The plausible looking results you used to get aren't necessarily as good as you think they were.

This is a problem with all web polls but this is absolutely not a problem here: you can measure quite precisely the amount of noise in the answers (seems to be about 20 to 50 fake results per age range) and deduce the approximate correct values for all ranges (assuming people that give wrong answers lie uniformly in the answers :)
The Mint transaction, which becomes part of the block chain, establishes consent that the given bitcoin address owns one BTC less and that simultaneously the given Zerocoin becomes valid.

Minting takes place within the block chain, unlike Dollar exchanges on MtGox, which are not directly visible as such in the block chain.

The Economist explains: How does Bitcoin work?
In fully synchronous mode, which is LMDB's default mode, everything is persisted upon commit. This is a memory-mapped database, not a main-memory/in-memory database. It is fully persistent to disk, it just so happens that it uses mmap() instead of read()/write() and a user-level page cache.

People are always confusing "memory-mapped" with "memory-only". LMDB is not a memory-only database.

This guy is right. A lot of it has to do with the demise of the PC too. You can't build a Napster on underpowered and severely restrictive phones and tablets, so the net is increasingly becoming the new cable TV.

However, by design, the internet is not destined to be like that, and it will not be. The past few years may have been an aberration.

As I understand it, that test used something like 32 server threads on a machine with only 4 cores. The UKUUG prezo used 16 server threads on a machine with 16 cores, which allowed all of the reads to run concurrently. The smaller number of CPU cores in the Zimbra test naturally reduces the concurrency advantage of LMDB.

There's been debates running now in the Bitcoin community what the new 'denomination' should be. So far, it mBTC (millibitcoins) is leading. You can still write it as 0.001 BTC, or 1 mBTC.

I'm just wondering in terms of psychology, what impact it has to write in ever decreasing denominations? Pricing something as 0.000232 BTC is much more difficult to read and understand. So, if there are more coins in circulation, this would hopefully not happen until much later. It will inevitable happen (if it is also a success). But just for adoption and ease of use in the short and medium term it will be easier to read.
One example would be Calendar. First they announce that they retire EAS for CalDav. A few month later they announce that CalDAV will be deprecated and only available for selected developers and other services should use the proprietary Google calendar API.

Which is kinda sad as Google could have really improved CalDAV with their move. Now it is back to "walled garden".
Most of the complexity of the human body (including its locomotive facilities) evolved well before humans existed. I think the analogy is just to put the time scales in perspective, not to equate their products.
