Ask HN: Estimation on Bitcoin mining costs
Hi,

I'm struggling to find a reliable source about the daily electricity consumption from bitcoin miners. Would somebody point me in the right direction ?

I'm reading quite a lot about bitcoins, and one of the main potential advantages are the low transaction fees. From what I currently understand, today's fees are indeed low, since most of the miners remuneration comes from the new bitcoins.

At some point however, the supply will stop, and the whole remuneration will come from transaction fees. I would love to see some rough estimates about how much this could be.

I've seen those two:
http://www.forbes.com/sites/timworstall/2013/12/03/fascinating-number-bitcoin-mining-uses-15-millions-worth-of-electricity-every-day/

http://www.businessinsider.com/bitcoin-versus-paypal-comparison-2013-12

According to this, the daily volume is currently at 250 millions usd, while the electricity costs at 15 millions usd (which seems quite huge to me). As a (very) naive estimate, supposing that all mining costs are covered as transaction fees and no new bitcoins are mined, that would account to 6% fees. Feel free to point me in the right direction if my reasoning is flawed.
You haven't had the pleasure of using VS 2012/2013 with Resharper, I see. My cursor lag while I type. Occasionally the entire IDE sputters to a halt, becoming unresponsive for seconds at a time, because Resharper decided to perform some static analysis on a 200-line Javascript file. On an 8-core, 32-GB RAM machine with an SSD.

Let that sink in for a second.

Yeah.
The difference between Threes and 2048 is that Threes moves the tiles on the board one space in the direction chosen by the player. In 2048, they move as far as they can go before being blocked by another tile or the sides of the board.

The numbers on the tiles are not a serious mechanical difference.

nope.

See, web ides have two fundamental fails that no one has figured out yet.

1) your browser context is not isolated; you have other tabs that kill performance, you have browsers you need to restart periodically (dns cache), or die because of dev javascripty things (eg webgl).

Restarting your ide all day? yeah, no.

2) no access to local files without a stupid plugin.

enough said.

There are some not terrible run-your-own-local web ides, but how is that any better than a fat client?

Its not a wasted chance; its that what you want currently cant exist in a form that isnt worse than the current solution.
I find it fascinating how so many people are content to crucify Mozilla for appointing as a CEO a man who had the sheer gall to contribute to a PAC opposing gay marriage.

Yet every time Rand Paul gets brought up his own opposition to same-sex marriage doesn't seem to draw 2 separate 200+ comment HN threads dedicated to how morally bankrupt he is. Is that simply because opposing the NSA is more morally noble than building an open browser that we feel inclined to overlook his baggage?

Better yet, what about people who support the Republican Party. As recently as April 2013 (i.e. not even a year ago) the Republican Party re-affirmed (unanimously) their opposition to same-sex marriage in their party platform. If you donate to or support a GOP candidate you are opposing gay marriage just as surely as if you'd funded Prop. 8 yourself.

It's for this reason that it's very important to separate a person's own political preferences from professional duties to the extent possible.

And since I apparently have to be worried about pitchforks I'll pre-emptively make clear: I'm proud to support, and have supported, equality of gay marriage rights.

The problem is that they are charging money for things that are free to distribute. I think most of the Graffle creators would be upset with this development if they were aware of how disingenuous this was. In fact, they (Graffletopia) are taking advantage of the fact that most of the items are not licensed in any way. For example: https://www.graffletopia.com/stencils/1197

This guy could very easily put his graffle on github (as Viget has done here: https://github.com/vigetlabs/Twitter-Bootstrap-for-Omnigraff... and License it as MIT, GPL, whatever.

$36 is not a reasonable amount to ask for. Nor is $24, especially in the days of Amazon S3 hosting, or even putting a slick static page up and pointing contributors and downloaders to Github. I respect the marketplace aspect, letting posters set a price on their work and taking something off the top. That's not dissimilar at all to what the Tuts+ and Medialoot marketplaces do. But they don't charge you to download their freebies, and charging someone for a membership to download more than one free item a month is total bullshit.

I don't have the information to be able to judge how Eich's views will affect his ability to be a CEO, but it's worth remembering that the CEOs of the companies that Mozilla competes with have been actively involved in illegal anti-competitive business practices (http://www.businessinsider.com/emails-eric-schmidt-sergey-br...).

Some of the more savvy and founder-friendly VCs actually say the opposite, eg. "Keep the team as small as possible until you reach product/market fit" (Andreesen) or "Perhaps more dangerously, once you take a lot of money it gets harder to change direction" (PG).

I think the overall point is not to never take outside investment, it's to carefully consider where you are in your product's lifecycle and what your market actually looks like before you take outside money. Refusing VC money if your market is huge means that someone else will take it and eat the whole market. Taking VC money when your market is small will kill your company just the same, because you won't be free to make the trade-offs necessary for a small company to succeed in a niche market.

I'm tethered on a mobile connection and all I can see when I try to view this is a blank page. :(
are you serious? How much do you make? Remember we are talking $200k pretax. So maybe $120k after taxes. That's less than half a down payment on a shit house in this area. That's maybe one year of market value cash compensation for an engineer with 5 years experience.

I'm not saying it's nothing, but remember that we are talking about this being one of the rare startup equity "success stories" that you hear about so often in the media.

Of course, I'd take a $200k windfall and be happy for a few days, but it's hardly a life-changing amount of money. I save that much money every 18 months (remember pretax). I wouldn't consider myself wealthy unless I had 50x that amount in the bank
the CEOs personality is the company's personality

Only in some organizations, driven by strong CEO personalities. In other orgs, the CEO fades to the background for maximum effectiveness. Mozilla seems more like the latter.

A promotion to CEO carries with it an endorsement of the whole person

I don't see that at all. It's not "monarch" or "mascot" or "most popular". It's lead administrator, with a specific set of duties that doesn't involve much (if any) electoral politicking, nor involvement in the details of employees' lives.

it's especially jarring given Mozilla's role and mission

Mozilla has a worldwide mission well-captured by the 'manifesto' here:

http://www.mozilla.org/en-US/about/manifesto/

People around the world have far more diverse perspectives on how marriage should work than what's preferred in SF, or other techie/urban wealthy-world communities. People ought to be able to collaborate on the Mozilla mission, in any particular staff or volunteer role, without an x-ray into their stances on other things, as expressed with their own time and money.

Also, privacy is big part of the Mozilla mission, and privacy is multifaceted. It's not just keeping things secret, but keeping things separate by convention: agreeing not to look, and not to act on, things people do in other spheres-of-life.

Such a practice isn't just polite, it's also practical. We get bigger and better organizations, and cities, and nations when vastly-different people can "agree to disagree", confine their controversies to specific bounded forums, and cooperate maximally everywhere else.
He didn't say that those were all of the people working on computers in the 40s.
This can happen for multiple reasons - but more often (IMO) is being driven by investors who know they need super outsized results, and at some point <insert giant tech co> will come shopping for the portfolio company.

So investors are willing to give founders significant liquidity so they are comfortable (or locked in to) "going all the way" (snapchat comes to mind [1]).

Remember, investors need billion dollar returns to return a fund. So giving founders a few million to pad their pockets, reduce their own risk, and extend their companies timeline is occasionally a simple decision.

This whole thread has been about Eich's actions specifically. You're shifting the argument to pretend it's just about his opinions. Now where do you stand on his actions, or do you want to keep dodging the issue and play around with false equivalences?
Patents and free software aren't necessarily incompatible. For example Raph Levien provides a royalty-free patent grant to software licensed under the GNU GPL that implements his patents.

It's fascinating how many hackers don't realize that there really do exist other hackers that aren't as morally superior. And not just at NSA. :)

I could see this being useful for those with CLI-phobia or just want to play with Linux casually. Still, it's not that hard to build the kernel; configuration is what takes a lot of the time. There's a menuconfig interface already.

Was the "your new anti-spam system sucks" checklist based off of this, or the reverse?
That's exactly the experience I had with Resharper when I installed it (and subsequently removed it for good after a few days) years ago when I still wrote C# code. I never understood the "Resharper is essential" attitude. Plain Visual Studio was just fine.
There were lengthy discussions about this in the [postgres] hackers mailing list and it turned out that, no, it wasn't.

I'm not really sure what Orwell and the 14th amendment have to do with my comment. I don't think I ever supported Prop 8?

I just don't see any way to exclude Eich from the workplace without exposing myself or others to harm. I think there has to be a shield between one's personal beliefs and professional conduct, only pierced by truly unacceptable things like felonies or abuse. As much as I dislike prop 8, I don't think a donation really rises to the level of a felony or abuse.

Is there a way to achieve the desired result (everyone but Eich is protected in the workplace) that I'm missing?
I believe PiouPiou (the app and the website they put up) was released in February 2014 and their story of being ripped off by Flappy Bird is just a shameless lie for people who don't check dates.

I would hope the point of Sandstorm is to eliminate system administration, so I also don't really understand the distinction between managed and self-run.

Also, a VPS is only $5/month so sharing one among several users seems like a premature optimization.

> However, with CEOs it's an entirely different ballgame. For better or worse, the CEOs personality is the company's personality. A promotion to CEO carries with it an endorsement of the whole person, there is really no way to spin it as if his personal views are not connected to his professional ones. In this case it's especially jarring given Mozilla's role and mission.

This is reallly overreaching. 99%+ of the people on here could not have told you who Gary Kovacs was before reading articles today, and still couldn't tell you who John Lilly or Mitchell Baker are. So the arguments for the "public face of the company" that have popped up today as justification for why random internet guy #7's opinion on someone is important really don't hold much water. It's fine to have an opinion and to express it, but it's just the insistence on the importance of that opinion that feels disingenuous.

But really, the proof is in the pudding. Nothing in the past has suggested that the work environment at Mozilla will suddenly grow toxic with this change, nor will there be a sudden change in the causes they advocate for or the larger community they foster. It is possible that these things will change for the worse, but that's already a possibility, and we have tools and a whole lot of people who love Mozilla to keep an eye on it, ready to help out if needed.
I apologize for being unclear if you perceived me as tearing down a fellow human being.

I absolutely share your conviction about free speech and a more civilized society. When I say I'm disappointed by this turn of events, I don't mean to say that this person should be shunned and punished for their beliefs at every opportunity, I am merely expressing the opinion that they're not a good choice for the job at hand. It must be possible to express this without descending into pitchforks mode - I'm sorry if I didn't manage to convey that. In any case, you can take comfort in the fact that I got nothing but flak for expressing this opinion :)

Pedantic corrections to follow (but useful ones, I hope).

There is one substantive gameplay difference between Threes and ArbitraryPowerOfTwo.

In Threes, a swipe moves the game board one square.

In ArbitraryPowerOfTwo, a swipe applies gravity to the game board in the swipe's direction until it settles.

I've played both, and that difference does not significantly affect gameplay or strategy.
You think you're being clever with your checklist dismissiveness. But your smug cynicism actually makes you one of history's greatest monsters, because...

The reverse, I think.
When you speak with your wallet you speak louder than you can with your mouth.

The overall issue here has less to do with his overall ability to be a CEO, and more to do with one of the functions of being a CEO. He clearly took a stance (again with his wallet) against the LGBT community, which fair or not will speak volumes to a large group of users, employees, potential users/employers and partners.

You're right, of course -- though the 1&2 vs. 2&4 is still a mechanical difference due to the random distribution of the new tiles. In Threes, you can be faced with a long string of 1s without seeing any 2s (and vice-versa); such a problem doesn't exist in 2048, since you can match the tiles with themselves.

Counting down from infinity, and other tricks with __del__
One way to introspect your own view-point is separating it from the current gay marriage debate and considering the alternate (but parallel) question "how would you feel if the CEO donated to a campaign for banning interracial marriages ?"

You could also imagine you were part of an interracial couple working for the company, how would you feel about bringing your other half to company events (xmas parties, dinners, etc.) knowing your boss was actively involved in trying to legally prohibit your relationship, etc.

If you'd see that scenario in a different light from this one, it might be worth considering why you consider it different and if your reasoning for doing so is sound.
You could keep the model logic on the back end, then expose it via a service. It wouldn't be necessary to duplicate model logic in both the front and back end.
Well yes for Ruby and Rails you would use RubyMine (Webstorm is included in it anyway), not InteliJ.

It really disappoints me that PG keeps changing HN to make it more difficult to have a discussion about topics of real importance and interest.

(Just catching up a bit late...) Yeah, I don't blame you for not being able to get around charging. The only obvious solution is being bought by Jetbrains, but neither of you may be interested in that outcome. :)

I'm in what's probably a minority position of wanting to have Python, PHP and Clojure all in the same place. I can get there, just not at a comfortable price point...
I think this is the real answer. I don't know that it's an insoluble problem, but it's a very hard one, compounded by the absence of a pre-existing societal consensus on what would be reasonable and fair.
Ask HN: Is Ryan Bates okay?
Ryan Bates announced he was taking a monthlong break from Railscasts -- he then updated saying he would be taking another month. It has now been about 7 months since his last message on the site, his last tweet, and his last commit on Github (except for one day in October). Is he okay? It is great that he is taking time off, 400 screencasts is a library if content to create, but he seems to have completely dropped off the face of the internet -- and with his last few communications sounding very tired, it is a little bit worrying.
The 1s & 2s are a very big difference because in 2048 you always know that if you save a 2 you will have another one pop up. There's no such mechanic in 3s.

I think Tor is probably the best option. For now, I've just put up a link[0] to the Turkish short Tor manual[1]. As far as I can see, the Turkish government hasn't block the Tor project's site yet(?). If they do, but they don't block my site, I'll look into hosting a download myself.

I remember reading about the Walmart IPO in Sam Walton's autobiography (an excellent book!) but I don't think he gave specific numbers. I think he owned pretty close to all of the company, but was in a lot of debt. He wrote that he was very worried about what his wife was going to say when she found out after he signed the deal to do the IPO :). There may have been a few store managers that had a small interest in the company, though.
I think the humour of the original spam-solution form https://craphound.com/spamsolutions.txt was always meant to be double-edged, and it was usually taken as such.
Yeah, that 1.40 to 1.00 ratio is eerily similar to the points dhh made on this interview about another infamous tech ipo :http://www.youtube.com/watch?v=jzERXJgi5vQ
Agree, it can be a little tricky for 1st experience...but for the ones that stay, is a convenient feature.

I think the comment next to the pic would make it worse - pics are the easiest/the fastest way of consuming the content. This is why the News feed is now really light - you can scroll/check out new pics really fast, and I like that. If I want "heavier News feed", I go to Twitter/FB/...

Pic stays in the News feed for 24h, as far as I know.
This marks one of the first sizable exits for a company built almost wholly on top of YouTube as a platform. A lot of people said that Google content partnerships didn't leave enough air in the room to allow for this sort of value creation. I hope this emboldens other firms to support companies working in this space, a lot of wonderful things could still happen.
I disabled all notifications on my phone that are not SMS / phone calls.

Hey Udo, I think the simple fact that you even thought of apologizing in a public forum shows you are not one of those of whom I was talking about. I can't say I saw your comments in the other thread, but your opinions below at the very least have some reasoning and basis to them, and don't seem to attack BE the person, as much as you disagree with his appointment, which to me is fair game.

Thanks for being cool about this :)
> The power adapter needs to be able to handle 100%

Actually it can't; there used to be a support article on Apple's site named HT2332 that details how Macbooks will underclock with the battery removed, because the adapter cannot supply enough power with the system at full load. Other manufacturer's laptops have also been doing this, so Apple is not alone.
When someone says to me "I oppose gay marriage but I have no animosity towards gay people", I hear "I am unable to recognize my own animosity towards gay people".*

It's not the most robust blog in the world, sorry about that :)
It took me at least 5 minutes to work out what to do. It is not immediately apparent you have to type in the selectors in the styling box, I thought you had to click on the animated objects. Pretty cool idea, I found it a little too easy, but as a developer already, maybe I am not the target market.

You did manage to throw in a few curve balls like needing to use general and adjacent sibling selectors to select particular elements beside other elements and inside of elements. I think it should get harder a lot quicker, would be cool to see an expert CSS version of this where it starts out hard.
