I think there's maybe a distinction to be drawn between transactions between individuals, which could be made in virtual doughnuts if both parties agreed, and a currency used in trade.

As far as I can see, btc is now two things - a protocol which could be used as technical implementation for any number of things, and also implementation of a currency which isn't backed by any concrete asset or entity (other than end users). For the currency, the main value and insurance against risk seems to be in the brand (i.e. what makes a bitcoin worth more than a foocoin).

But it's trivial for a government to kill commercial use of btc as an alternate currency within their jurisdiction. It's not legal tender and therefore can be banned for use in transactions by registered companies - that can be easily enforced by tax authorities and police. It's also quite justifiable on the basis of collecting taxes, protecting the economy generally, and protecting citizens from being caught with paper that isn't backed by law or national banks. Black markets are by definition illegal - the only question is to what extent they are tolerated and that is largely a question of their size and impact on the formal economy.

Pretty much every review of Apple gear has people moaning about bias in the comments.

I'm not saying there is any favoritism, but certainly the perception amongst Anandtech readers is that there might be.

At the end of the day, there's no reason why the writers at Anandtech would be any more immune to access journalism than other folk who have tried and failed.
That was on Etherpad. I wondered how the same text ended up on Stypi and how they are related. I found this:

> Why would Bitcoin be immune from the factors that cause fiat currencies to collapse?

I think the argument is that the more people whouse it the stronger the currency becomes. It has an extremely low barrier to entry because it can be used alongside other currency, and on top of this is decentralized (no "off" switch).

If fiat currencies are replaced by bitcoin, then yes it probably would become "stronger" (ie, more value in relation to other currencies). That's assuming a country who's currency/economy collapsed decides to use bitcoin as the national currency. I don't see why they would at this point, though.

I do think it's entirely susceptible to sudden value loss, at least for the next 5-10 years.
I guess I'd answer the question with a cui bono question. Why would someone of Paul Graham's standing need to fake this? What would be his incentive to do so? He has nothing to gain from faking it. And I can't think of anyone else who stands to gain, either.

Occam's Razor explanation is that he just thought it would be cool to show.

There is a reason why the GoPro is still in the form factor it is in. It is terribly hard to pack most of the GoPro's features into a small volume, they went with something cubish and built accessories off of that. The Glass couldn't keep up to the demands many fans would have and I imagine there is a struggle within the company concerning the increasing demands for resolution, frames per second, and image quality with the volume of the form factor they have.

That said I do see helmets with HD cameras and wireless controls in the future. Trademark™ and all that.
But the problem is that, among all the things Bitcoin is trying to be, one of them is a currency. A pseudonymous decentralized p2p payment system is a reasonable idea, but since every transaction takes place in a currency with bad fundamentals as a currency, it's not a particularly good implementation of that idea.

"IT" can go up to two hundred miles per hour, gets three hundred miles to the gallon, and is an all-around better mode of travel. The only problem is that "IT" is controlled by a quite painful and uncomfortable method; using four "flexi-grip handles" that somewhat resemble erect penises; two held in the hands, one in the mouth, and a fourth handle which is inserted into the anus. It also transpires that the vehicle can be operated with buttons too, making the phallus-like controls an unnecessary discomfort. Garrison invites many important investors such as Bill Gates, Steve Jobs and Yasmine Bleeth to see how "IT" works. Despite this unorthodox control mechanism (which is uncomfortable to the citizens of South Park), "IT" is still considered better than the airlines and Garrison is a smashing success.

Removing the camera (+mic) would certainly fix the creepiness for me - and make the problem you mention in the next sentence worse. Having a screen in front of your eyes 24/7 can only distract people. Having a camera and mic on it enable you to interact with your surroundings; and while not all apps will use them, it changes the focus and center of the device - thereby changing the way people interact with it.
The Other Side of Being a Young Developer
It is a well written review.

Note that the D700 specs match closely with the R9 280, 280X, or 290, cards which sell retail for $349 to $449 or so each (the Mac Pro has 2 of these in the 2x D700 config). See https://en.wikipedia.org/wiki/AMD_Radeon_Rx_200_Series . The 2048 shaders would match with the 2048 number for the 280X, I think (if I am reading the chart right).

The W7000 is the much more expensive "pro" version which has ECC RAM on the card and much less volume in terms of sales.

Elon Musk Thoughts on transitioning to 100% renewable energy
Setting an end of life for Python 2 would be the forcing function needed to ensure Python 3 is reliable and the migration path is clear. Knowing the end is coming would drive us (the community) together to discuss and resolve these issues.

I for one never even considered that C extensions would be a serious road block. Which is obvious now that you mention it. And my main point, I've never bothered to research moving to Python 3 because there's no sense of urgency.

If that fails, I'll end up watching an episode or two of a tv show, playing an instrument or something away from electronics mostly so I'm not staring at the problem I'm blocked on.

I lurked for a long time, and recently bought in.

Perhaps the timing was bad, but I'm not a stranger to investing in the stock market (technical trading, mainly) and the patterns I see are favorable (although not definitive in any way).

I also just like the idea of bitcoin. I see people bash it all the time for not being a real currency, but the criteria they judge it on applies to all currency besides direct commodities (I'll trade you one cow for two goats).

The USD has as much real value as monopoly money. The gold which used to back it also has no real value. These currencies are a representation of value, but hold no value themselves.

I feel like bitcoin is slightly different. Although it represents value like other currencies (albeit with much volatility) it has the unique characteristic of being distributed and non-regulated (in the sense of visibility into transactions). I can send anybody with an internet connection (or hell, even a street address) bitcoin. I can store enormous amounts of it on in multiple places, encrypted, and effectively have a safe I can access anywhere that only I can open.

So it does have intrinsic value in that it does what other currencies do, but better.

Will it live or die? Live, I hope, because I've got a horse in the race now. I would argue though that if bitcoin were to fail, something very similar would take its place.

The energy and interest you have is a tremendous positive. Don't take it for granted. It's something to nurture.

What exactly is making you feel bad - what are you thinking when you have that feeling? i.e. what thought is stopping you and why is that bad?

[OK, I'm guessing in the following - you'll find the true answer in the above questions] You say you feel bad because of a lack of mastery, but what level of mastery counts?

I think it's the lack of a goal: a defined point where you say "ah! I've done it!", instead of a continuous never-ending slog. There's always more you can do in the bigger picture, but you can choose a goal at a point that in some sense is a completion. Artificial in a way, but also on top of something, a logical boundary.

That is, a specific doable task that can be done pretty quickly; with some challenge, not too much - a level that, from your experience, is definitely doable by you; that is clear and definite, so you have a direction/guide to keep you on track, and so you know when you've reached it (so you can stop, and see how far you've come, and a take a rest to choose the next one).

Finally, it must have some meaning to you - it could be to just learn some technique to some standard... but better is an actual project that you want to do: a simple parser, an animation, a tool that you'd like to have, implement an idea, copy a game or tool or library or framework or language or app that impresses you (or some part of it). But note that it must be doable, by you, in reasonable time. So, if too ambitious (or you realize it's too ambitious as you go along!), break out simpler and simpler versions of it, or sub-parts of it - provided it still has meaning, a definite end-point, and is doable.

Of course, as you say, you are learning stuff in this spiral, and you'll get cross-insights from doing different things. It's just that you feel bad about it - I think having goals would help. [But see the questions above...]
This whole light thing seems a bit out of proportion, like being paranoid of people wearing shades in case they are eyeing you up (which is more than half the reason anyone wears them in the first place).

VPN + HTTPS for good measure
I'm such a person. I've been active with BTC, I've mined and traded (both to a nice personal profit), but I think BTC is a loser. I invested in BTC the same way I invested in one-hit wonders like Zynga: very temporarily.

Perhaps we can ask each other some questions:

My first question: BTC is designed with very limited bandwidth for transactions (right now it can only do 7 transactions per second). Is there an actual solution in place to deal with this? All I ever see is hand-waving about how the limits could be raised or eliminated, though that appears that it would create a problem with block chain size and bandwidth.

Is there a proposal someplace that actually addresses BTC's current lack of capacity that doesn't just create a rather massive bandwidth and storage problem?
Wait, someone expected X security to . . . well, to exist? In this decade? Wow.

Eric Schmidt's 2014 predictions: big genomics and smartphones everywhere
For starters, no one is saying it's pg's job. The interviewer asked him if he felt there was anything he could be doing to get more women into YC.

Of course this is just my opinion, but to me the tone of the interview sounds as though the interviewer was suggesting that pg should be doing more, himself, to get more women into the field.

Second, "encourage" does not mean "order someone to do something." No one is going to up women, putting their hands on their shoulders, shaking them, and telling them they must be developers! Instead, they're creating spaces that are welcoming and friendly to women. They aren't forcing them through the door; they're opening it for them and showing them all the delicious cookies inside.

I never said "order someone to do something." In fact I specifically used the word "encourage," but I guess you can twist my words to try and further your agenda. Stating that you want to create female friendly spaces is inherently sexist. I don't know, I think we just differ philosophically and I am more of the mind that people should be friendly regardless of what/who you are. I just don't think that we need special programs for every single "group" that is not interested in something.

Yes. There are plenty of initiatives to get more men into nursing, fashion, and teaching. Just because you didn't take the three seconds to search for them doesn't mean they don't exist. You don't hear about them because, what a shocker, you aren't part of those communities. It's almost like you're on a website dedicated to tech culture or something!

As someone who originally studied to be a male nurse, yes I am aware of those programs. Please try to not be so condescending.

Determining which N's it exactly works for is a math, not a programming puzzle, however. :)
