"hell bans" are described by CodingHorror.

Try turning "showdead" on (in your profile) - you'll start to see a few people who have been hellbanned. Some of those people know that but continue posting anyway. Some of those people just made a mistake and got hellbanned and could probably be unbanned.
This is a false dichotomy. Knowing how to grep is essential, but that doesn't mean you must forego other convenient tools just in order to preserve your "hacker cred". Use whatever is most efficient to do a specific task.

This article is interesting, and it also contains a link to the original paper which is more than many article do.
I agree. Leaning over and looking at the fretboard puts you in a really bad position.
I think the incentives of the bitcoin system to hoard money and the massive bias towards early adopters will be the downfall of bitcoin. All the advantages of anonymity and irreversibility are voided if there is every reason to keep hold of your money and let it increase in value. Several people on HN claim to have hundreds of thousands of bitcoins, making them worth more than 0.1% of the entire economy. Whilst the real world has its (possibly unfair) share of billionaires, the majority of these have come through substantial business innovation. Bitcoin "billionaires" come through luck and early adoption, and in my view it makes it more unfair than our current system.

I think that bitcoin will continue to have some success in areas that wish for privacy, but will not reach the heights that some people predict.
They are taking a huge risk with this investment. With the mining reward set to automatically halve in 2013, and the currency still in its infancy, its a bold move. And despite dropping 6 figures on the hardware it barely a percent of the total hash rate.

Why 'eureka' moments happen when you aren’t trying
Unfortunately our literature review didn't turn up Tahoe-LAFS when we wrote RACS, possibly because of differing terminology. It would have made a great addition to our related work section.

I don't disagree with you, but there are a significant number of hereditary billionaires (in the real world), which inherit money through luck and early adoption (of business or banking)
We just don't have the money, that's the biggest problem. Sure, we have a few people in NZ that are very wealthy, but they aren't the type to spend it on stuff like this.

You'd think that, except invisible banning is used on hacker news and if you turn show-dead on in your profile and then go to the profile of someone who is 'dead' then you'll more than likely see months and months of them posting as an invisible person.
I really don't like it at all! Don't get me wrong, as an engineer I think it's a very exciting project. But as a guitarist, who spends a lot of time teaching others how to play, I could not think of a more misguided idea of what the instrument is about.

gTar works on the assumption that playing the guitar consists of putting your finger on the right fret at the right time. Imho this is as wrong as assuming that programming consists of pressing the correct keys in the right order. (million dollar idea: Teach you programming by putting LEDs on your keyboard! $599 only).

There's a common misconception that learning to play the guitar consists of learning where to press; after all, isn't this what tablatures are all about? I tend to put much more emphasis and practice on right-hand techniques. Other comments in this thread speak of 'early reward' or fast gratification; stubbornly trying to bend your left hand in unintuitive positions while your right hand cannot cope is NOT the answer.

Side-note for beginners wanting to learn the guitar: Learn a few chords you don't need a lot of them, then practice right-handed techniques (you can find plenty of examples off Youtube) religiously. Early mastery of this would rapidly give you comfort around the body. You can then get your gTar, read your tabs, or do things correctly by watching videos of your favorite artists and learn slowly to reproduce their songs.

Again, the engineer in me thinks this is an amazing project. However I would never recommend it as a guitar teaching tool.

With an API - I could actually do a ton of things with this, for example:

- Match up to my user base to handle the authentication of phone numbers

- Automatically invite the right people to specific calls

- Log attendance to calls back to my system - so we can build our own reports/handle no-shows

- Sync the recordings back to our storage for streaming by users later

Please build an API!
I believe it was 'Kill Hollywood'. You might as well have Henry Ford saying 'Kill Horses'. When a viable alternative exists it will gradually replace Hollywood. Just like every other industry.
That was my opinion in the beginning, but I'm not convinced anymore. First of all, the bitcoin billionaires have a strong incentive to spend, because if they don't, the currency will crash and they will lose their money.

Second, if you were to create "inflatacoin", with a small but real inflation rate, who would adopt it? It would probably be better economically speaking, but people prefer putting their money in things that stay stable or grow over time.
The other linked illusion - (http://io9.com/5906432/an-optical-illusion-that-explains-the...) - is neat. It (The Troxler Effect) explains why those of us who don't block ads tend not to even see them.

I use optical illusions as a gimmick when I talk to doctors. I do service user involvement with mental health stuff. Clinicians talk about "accepting the reality of the patient experience", but sometimes that concept is quite weak. Showing someone an optical illusion (the grey grid and green bar[1] is great for this) and asking them what colour they see - and then proving that they are wrong - is powerful illustration of how strong the mind can be.

> I personally see this as a clear sign that Bitcoin is fundamentally unfair and easily gamed.

Curious that you used the word "unfair". It is quite likely that the fairness of bitcoin, is not related to it's future viability.

Disparity is alive and well in the real world, and seems to be doing just fine.

I don't see how the hoarding/early adopter thing would destroy bitcoin. Bitcoin isn't fair, but lack of fairness doesn't necessarily make the project unsuccessful.

It's ironic that the Met Police, fresh out of a phone hacking scandal have proposed making things easier.
Early adopters used powerful computers; then GPUs; then GPU farms; now people are using FPGA clusters. They've seen considerable investment in hardware depreciate, and now they're stuck with a massively powerful setup that isn't much use to them. (Perhaps well-funded scientific groups should start buying all these hobbyist GPU farms while they're being sold cheap and put them to use folding proteins or modelling whatever?)

Will anyone go to the expense of an ASIC?

Would a well funded group with access to FPGA technology early on in the chain, when others were using GPUs, have been enough to crash the currency?

And does anyone believe that a government would not be able to destroy bitcoin, trivially, by spending a few days mining?
Right, but BAs have been doing SPSS, SAS, Mathematica, MATLAB, R etc, etc for decades. Any BA worth his or her salt could pick up these new things without breaking a sweat - they are not rocket science, and the value of a BA is in their knowledge of statistics and industry domain knowledge.

A DS is a BA without sufficient industry experience to know there is already a job doing what they do...

No. The "hoarding" argument has been beaten to death. Evidence shows people are not hoarding the coins: every day, 40 thousand coins change hands on the single largest exchange: http://bitcoincharts.com/markets/mtgoxUSD.html This is six times the number of coins created daily (7 thousands).

In other words, people are not hoarding them, but are trading them very, very frequently.

And this is just measuring MtGox's volume. Other trades (merchant sales, other exchanges, etc) are likely surpassing MtGox's volume in aggregate...

Anyone know enough about Amazon and Bitcoin to know how many bitcoins you'd get for a $10,000 spend on Amazon EC2 GPU clusters?
Are there any statistics what those might be used for? Is there a list of sites/services that use Bitcoin with published numbers?
The most the government could do is generate all the new coins, this would drive up the price of coins until it became economical compete.

Given the almost limitless divisibility of bitcoins I don't think it's much of a threat. I'd be far more worried about laws being passed that made bitcoins punishable by jailtime.
Let me tell you something

If you're reading "just tables" without, or with simple relations and conditions, it's ok (because, as you pointed out, that's basically SELECT with)

The problem is when for example you have inheritance, or moderately complex relations.

Then you'll see Django spamming your DB with requests and the DB may be fast but the operation will be slow because of the sheer number of requests.

So yeah, in a sense you can optimize for it, or use SqlAlchemy (which is good, but it has a different philosophy than the Django ORM in the way it's used)
If you want justice you'd better hope the Judge follows the law instead of his own opinions and prejudices.
In other words, Google is willing to share its users’ contact information with Facebook, but only if Facebook is willing to do the reverse.

No doubt those 900 million users are a juicy target. Sorry, I don't think Google is being altruistic here and it's perfectly fine, since they're a for-profit corp.
I'd say pick the one that's compatible (or has great libraries) for what you are working in (eg. .NET, Rails, Django etc.). Especially in the beginning of a startup project, it's important to maintain efficiency.

From what I've seen, most start out with a RDBMS and switch to hybrid RDBMS/OODB later on. I've also seen some switch entirely to OODB from RDBMS and back into a hybrid.

There's also a case for schemaless document oriented databases like MongoDB. Honestly, I haven't seen 'serious' uses of document oriented databases other than for distributed caching.

In general, 'big' data needs structure.

One of days it might even become common to see most browsers support indexeddb (sql like) and local storage (kvp like).

So back to my point; efficiency, compatibility and familiarity is key for rapid application development, which is a must have for start-ups.

Just as when committing murder there's a big difference between something premeditated and something done by negligence. The difference is that of intent.

The data by itself has no meaning, unless interpreted.

So the question should be, did the user have any intent on sharing/distributing the creative work to others, or was he just a user of a protocol he didn't understand, ending up uploading just because that's how the protocol works?

A lot of non-technical users do not know that they are uploaders when using BitTorrent. They just have a client installed by a friend and upon clicking a link the download begins, just as it would through HTTP or FTP.

And I see a clear distinction here between somebody doing that, or somebody that does it for the money or for glory. For instance we have a lot of prowlers in my city that sell pirated CDs at street corners to people that are passing by. The PirateBay is also filled with movies shot with a web cam in a movie theater, done with the express intent to redistribute those movies, either for money or for the thrills. Many times movies that were distributed as press releases end up on the PirateBay in DVD-quality long before the DVD was released. A lot of hacked copies of Windows are also on the PirateBay, many times with customizations and mallware included. And so on.

There are many shades of gray here. You can't put all the people in the same bucket. And I think that the people that should get punished are those that start the redistribution chain in the first place, not kids, not grandmas, and not the online services that act as the middleman (many times without their knowledge).

This is another reason why I think DRM is a misguided and broken attempt to fix piracy, when watermarking is so much better from all points of view.

1) It requires implementation. Implementation is often costly and sometimes infeasible (e.g. Vimeo having to build feature which lets you download all XXXgb of your videos at once).

2) It opens the door to litigation. "I told gave <web service> <piece of data> and now I can't get it back easily. Give me money". Don't laugh now, because we all know that laws designed to protect IP tend to be abused (patents, copyright, etc.). I'm sure that Europeans will set the precedent for this one with their tracking opt-out laws.

3) What format should it be delivered in? Can Facebook just give you a 100Mb HTML file with all of the things you've "liked" or does it have to be more accessible? Is a purely machine readable format alright or must it be human readable too?

Of course, it's possible to create a law which gives just the right amount of data freedom to users WITHOUT turning every social website into a horrible Dropbox clone, but there's a very fine line between making legislation toothless and making it pedantic.

You, along with most people, do not understand how copyright works.

Yes you can backup or transfer your copy to other formats or media. But you cannot redistribute that copy to others, even if those people have a license for it.

And yes, archival and format-shifting is possible because of fair use clauses, but those clauses do not extend to redistribution of the work as a whole, even if done for noble purposes and in the public interest.

And even in cases where you could redistribute parts of the work, with the purpose of criticism or parody, the end result and intent matter a lot when judging if fair use clauses apply or not.
The point is it's less far than it looks (humans are bad at judging vertical distances), and giving a real-world comparison makes the real height easier to conceptualize than an abstract number.
