How would you convert bitcoin to USD? You need a buyer. If you go through an exchange, you have to prove your identity to the exchange. If you go through an individual, there's a risk of not receiving your money if you make the transaction online, and if you do it in person, you risk your identity again.

There's no guarantee for either party that the transaction will be completed successfully. Either party can take the money and run. So you risk your money or your identity either way.
I have two young daughters and my mother is always on about this. It's her contention that most of the young girls that end up abducted and murdered were inappropriately dressed, and that this attracts sexual predators, so she's keen that our girls are dressed well. Honestly, since she pointed this out and I started paying attention to descriptions of what victims of this kind of crime were wearing, I have to say she's got a point. Not to blame anybody but the perpetrator, of course.
I find that generally, when this happens it's due to a bad / non-existant migration policy (it's just as important as your branching strategy to keep migrations solid). Migrations should be able to rebuild an entire database from scratch. If it can't then the migrations have been screwed up.

I'm only slightly unhappy about fish requiring python (actually python2 in Arch Linux). AFAIK, this is needed for the web server configuration interface. It'd be much better if fish could be built with this as an addon or optional dependency.
That simply isn't true, it is a mathematical fallacy people often fall into when dealing with infinity.

To take an extreme example, imagine that ALL bitcoins have already been mined, and there are no more bitcoins to be found. Then imagine that they start blacklisting bitcoins at an incredible rate: HALF of all bitcoins in existence are blacklisted each year. Remembering that it is possible to subdivide bitcoins (and arbitrarily far, given minor changes to the protocol), in what year will there be no coins left?
It looks like they also accept international customers. Can't think of any reason not to use them instead unless you live within walking distance to fsdata!

"pela" is something offensive I guess?) "mutta" ('but'... apparently it considers "mutt" a bad word.) and anything containing "ass" (ssa is the inessive suffix and Finnish has vowel harmony. Fun.) and lots of others get completely mutilated.

Roughly, graph reduction execution represents an expression as a node, with an edge to nodes of subexpressions. A value of a node is obtained by walking through it's children, setting the value of each node as the recursion winds down.
String reduction simply modifies the expression itself. This does not eliminate common subexpressions (a() * a() will reduce a() twice), which is why graph reduction is favoured. In a parallel world, you often don't care about the extra work if it reduces the number of synchronisation.

There's a very good reason for using HTTP basic auth: if you want to store password hashes on your server using a modern scheme like bcrypt or PBKDF2, you can't use digest authentication. The author suggests rolling your own authentication scheme based on HMAC-SHA, but then all the clients need to implement this scheme whereas HTTP basic auth is already part of most HTTP libraries. And do you really trust yourself to get the crypto right?

HTTP basic auth over SSL seems like the way to go - and you need to use SSL on your API anyway to prevent hijacking. The points about not allowing HTTP access to the API make sense, but avoiding basic auth entirely isn't a good security tradeoff.

Perhaps the person (or persons) is concerned that bitcoin will become even more successful and will threaten powerful institutions like major world governments. I wouldn't want to be Julian Assange right now, and that is a perfectly sensible reason for the inventor of bitcoin to wish to remain anonymous.

A different reason might be a fear that if a single inventor were known that bitcoin would become vulnerable to "change it this way because the founder says so" attacks, weakening the decentralized, P2P nature of the currency. (This is a less plausible reason, but still valid.)
Is it numbness or pain? I see noone brought up 'Carpal tunnel syndrome' yet. Can it be CTS?
I've been on a project that was doing exactly this. It's a giant PITA and we found ourselves slowly implementing something that looks a lot like South in order to mitigate all the problems we encountered. So we dropped this approach entirely and just used South. With a half decent migration strategy it's so much more robust than messing around with SQL. Unless there are specific edge cases that a migration tool can't deal with, use one.
There's a lot of truth in this. I can't stand hipsters because they're a bunch of cargo-culters who have no idea why they're rebelling, or which targets deserve it and which ones don't.

I've worked in corporations. I have the right to hate them. I have more insight into corporate evil than 99.99% of people alive. If you dick around in Williamsburg and haven't seen the morning sun since college, then you don't understand why corporations do what they do and have no right to complain about them.

Reflexively hating suburbia, for one example, is the epitome of being suburban. I'm surprised by how many people don't get that.

Apple deserves a lot of credit for their support for WebKit, particularly in its early days. But even old time apple webkit devs will readily admit that the existence of Mozilla made WebKit much more viable back in the day. Mac's had practically no marketshare during those days. The fact that Mozilla existed and had a reasonable amount of marketshare across platforms made it possible for Apple to ship anything other than IE as a default browser on Mac. Mozilla maintained the incentive for webdevs to support non-IE browsers, and use standards-compliant CSS. Desktop Safari as a default browser would not have been a viable product if so many webdevs had not already worked to make their sites work well with Gecko/Firefox. Webkit sends "like Gecko" in its user-agent string for a very good reason.

In other words, a lot of the web kept using standards (and not IE proprietary stuff) since they wanted to work in Mozilla browsers. And all of this content tended to also work well in webkit as well. This made Safari useful and viable. So, its at least somewhat reasonable to say that Mozilla and Firefox are perhaps primarily responsible for keeping the desktop browser market open for non-IE products. Their existence and marketshare allowed the newer browsers to compete on the basis features and performance and not be hobbled by poor website compatibility.

Given the nature of JVM agents, this means that the Tikipi backend, should it choose, may access all the data in the production application. Correct?

Tesla said that he could simulate the behaviour of his contraptions to the smalles detail in his head and without exception, they ran that way once he built them for real.

I think that a good programmer should be able to do this with his programms, and without flattering myself I can say that in 99% of the cases when an error happened, the answer occured to me almost instantly or after a few moments of thinking and trying to simulate what happened in my head. I have to confess that these were instances when the whole code was mine. Working on code you don't really understand is a major mistake. But this is another issue..

Sure it remains the 1%.. but my point is that developing the thinking abbilities instead of debugging tools is a far better alternative.
I'd say the distinction still matters if a court and subpoena still needs to be involved. The distinction disappears when the police can get access to the footage without any probably suspicion.
Well, the mean could be affected by people not finding what they want and moving on to another site, so a high mean time could be a good thing.

> If you create unnecessary, reducible complexity, then add even more complexity on top of that to manage it, you're doing it wrong.

I believe the fact nobody has been able to reduce the "reducible" complexity you point out for the past 40 years is telling. And no, the NeXT .app folder thing does not reduce it - it replaces the shared library "problem" with other problems (security and just plain malfunction) through obsolete duplicate libraries that may or may not get updated by someone other than the packager.

> First of all, note what you said: every developer.

I'm sorry, but I don't think BeOS was ever aimed at someone other than developers. It would be quite surprising if Haiku were aimed at a different public.

Again, I fail to see your problem with package management. My mother uses a Linux machine and the only contact with package managers she has is the auto-update feature - and her machine is working for 4 straight years without a full reinstall, which is more than most other OSs can say about machines that are not actively managed by someone knowledgeable. I manage dozens of Linux machines and I never experienced the package management disasters you describe.

Maybe you should get some first hand experience and, dare I say, read the manual. If you experience a significantly larger number of disasters than your peers, the problem is most likely not the tooling.
So after some years of trying to avoid being arrested the cops no longer need to worry about due process or law or anything, they can just murder me? Would you care to put an exact date on when the police get to switch from "must follow the laws" to "can kill on sight with no regard for laws"?

Cheer-leading I can at least understand. Even if it might be inadvisable due to the sexualization issue, you can fully understand why young women want to do it and it's a lot of fun for everyone involved.

The guns and healthcare issues have me stumped though. As a conservative voting Brit, Thatcherite and Reagan admirer, you'd think I would be a natural republican sympathiser. I listen to 'right wing' american naratives on these issues and they just make no sense to me at all. I understand the history behind how America got into the situation it's in with these issues, but the justifications for blocking credible reform are just incomprehensible to me.
Wait, so everyone that wants to own a gun is a terrorist? Please, if you want to live in a nanny state I don't mind but don't act like it's any better.
Using Kinect for 3D scans - amazing hack

For example, Lojban uses a method of saying phonemes to describe words, like Hebrew, so the number 100,508,290 is just an utterance rather than a sentence.

Rather than

One hundred million, five hundred and eight thousand, two hundred and ninety.

consistent, simple, fast, unambiguous. numbers are a common occurrence, so they should be fast to speak, So when the extremely common occurrence of me forgetting to include sudo for a command that requires escalated privileges, I expect that task made easier.

As an alternative, think of it like this. the specific operation of "put the whole previous command in this place surrounded by new text" is actually a common idiom in calculation programs. Commonly called "ans". Mathmatica actually marks the results of all its computations with a tag (I think t[n]) so you can recall arbitrarily.

That's not to say I'm a stick in the mud, if "sudo !!" sucks, make it better!

How about something that turns a command into a postfix command? Or actually having a hotkey recall the previous command? Maybe a hotkey that looks at the text in the argument then searches up the history to replace? so if I type sudo rm^U it takes 'rm' and searches up history, replacing it with the first match, "sudo rm -rf ~/opt/java"? Lots of possibilities!

Honestly sometimes when I'm on my phone and I get a linked in email I won't click the link because the experience is so bad. I'm petty sure it starts with more than 2 possibly 4 redirects and then it shows you that spinner for a long time while it loads data. Are the ajax calls returning a lot of days that is never rendered? Are the ajax calls too slow? Why does it have to redirect so many times? Maybe if they had a mobile debugger they could figure it out.

An application like linked in should not require a native app. The website should just work well in a mobile browser.
>how can you even prove that?

Fair point, but I suspect the only way this discussion ends in an philosophical debate about perception vs reality.

My overall point is what is end-goal objective for someone who would implement such a technique? To make money? The author is suggesting that it's easier and cheaper building your personal brand (and thus reap benefits) than to work hard organically. Furthermore that we should be concerned that it is possible. My perspective is "So what? These people are running very risky lives and will get caught. Even if they don't, they still live carrying a massive burden of risk". Social network have equally positive and negative powers associated with them.
Depending on how much you can exploit SHA256 you could take all chance out of getting the longest block and earn the new coins or fees as often as you want. I don't know the specifics of the moving average of difficulty but you might be able to game it by backing off and letting the difficulty reset before finding the right hashes quickly again.

If you're already starting at 5% of the coins, and you're steadily gaining more, and the currency is tending to deflate, that sounds pretty close to printing money. Sure you're constrained but so is the Fed today in its abilities to print money effectively. Additionally, having so many BTCs pretty much ensures you can find a way to continue bettering your financial situation, generating interest or something more creative.
Diagonal proofs like the Halting Problem say that in general you can not prove properties about all programs in a Turing complete language. Thus, there is a class of troublesome programs.

Likewise there is obviously a great number of programs in Turing complete languages that you can prove properties about. Thus, there is a class of pleasant programs (or [program, property] pairs).

We do not know for certain how many of the programs that we want to write that is in each class. I would venture a guess that >99% of all programs ever written are in the "nice" class. If it is really impossible to reason about some property of a program, why would you think it works?

This article seems way off point for hacker news (better fit for reddit) - and even if you were to make the stretch that it fit in the intellectual curiosity category, it's a little weak on that too.
I don't see the big thing in this. The title of the article is "How to become internet famous for $68" but I can't seem to understand in what way Santiago Swallow is to be considered famous. Kevin Ashton writes that he bought 90k followers. According to the screen shot, it seems like he lost almost 5 000 of those, not a good turn out. As the article also states:

"Santiago Swallow may be one of the most famous people no one has heard of."

Fame is based on how many people knows you. If no one knows your name, your not famous. If the Santiago setup doesn't generate new followers on Twitter, the tactic isn't very successful.

From my point of view, Santiago Swallow is (was) a very static Twitter account that haven't come to life.

To call a thing like this successful, there has to be other, external forces giving life into the persona. From what I can see, everything about Santiago comes from the creator, not from anyone else.
