full disclosure: I own a small amount of dogecoin.

Original spec for Dogecoin:
https://bitcointalk.org/index.php?topic=361813.0

We're on block 65K. The first halving is scheduled for block 100K or Feb 14.

Dogecoin trade volume is around #2 #3 in cryptocoin markets, so actually it's very liquid. In practical terms, there's been $7M USD in trading volume in the last 24h. Converting 10s of M Doge into BTC into USD would be very easy.
Ask HN: Where would you start learning about basic devops/server management
As per the title - if someone had little to no experience of managing a Linux based server that will host web applications, where would you start them off?

Any good online resources? Books? Courses? Blogs etc?

thanks
The Problem With Wearable Tech Today
I would prefer to do my own thinking, not have the computer try to outsmart me. It can't, and it always hurts my sleepcycles when it tries.
Yup. That plus art, poetry, and all kinds of little one-offs that individuals can make online and get money for.
Unfortunately as a society (Canada) we're a little too conservative when it comes to entrepreneurship. Where I live anyway, the only path to 'success' that anyone can envision is working for a large corporation...
Not to be pedantic, but the 2 X 2 TB usually means it's a RAID setup, so it's actually 2 TB, not 4. Or am I wrong?
I know the gaming world is making a big mess about this but as others have mentioned, it's nothing other than marketing. Doing promotions like this for Machinima partners/affiliates is nothing new. I also don't see how it differs from publishers sending free games to people to review on YouTube.
Really interesting concept, but what other information can you grab from a user who has never visited your site before?

There's the example of location, and I guess you can also get browser information (mobile device vs. desktop), but other than that, I feel there isn't that much in terms of context to work with with first-time anonymous users, which is the most common case for A/B testing.

Would love to hear how else you're classifying users, and what other buckets you're using.
Clearly I need to work on my sarcasm-detector... :)
and the NHS Number should never be disclosed its effectively the equivalent of your social security number or ni number it's what the NHS uses to track you in the system.

Its why every test you do in the NHS is tagged with your NHS number
It's awesome to see a Bandit-based algorithm being used. I think this is really similar to what is called Adaptive Sampling (also based on the Bandit problem), and it's been used in multiple contexts. My favorite has been in clinical trials where adaptive sampling was able to save lives.

I really, really, really wish that the Linux CSPRNG would quit having its flaws papered over. A fellow submitted a patch to implement the Fortuna CSPRNG years ago, and it wasn't accepted because of a misguided belied in entropy estimation.

I'm not saying that Fortuna is the One True CSPRNG—it's not—but any clean design would be preferable to the current Rube Goldberg mechanism. I'm pretty sure that /dev/random as it currently stands is secure enough, but 'pretty sure' isn't very reassuring.
Why do people always insist on posting sub-second performance benchmarks in blogs? Is it really so hard to put a for(var i = 0;i < 1000;i++) {} around the code?

I'm not talking about making the benchmarks actually being reliable, but make them at least pass the most basic of inspections.

Your computer could be doing anything in the few seconds that your application ran. Is your blog really that worthless to you that you couldn't wait 5 minutes to establish that what you're saying holds water?

edit: okey, I need to sleep a bit better, I'm coming off bitter again :P
Sorta neat, but I wish there'd been a landing page that explained it, and said "click here to signout!". Because now I have to sign back into everything...
ITER nuclear fusion reactor enters key phase
3.13 is the first release with full opensource Intel Broadwell drivers - switched off by default though.

So by the time Broadwell actually lands in Q3-Q4, the kernel should have stabilized nicely. Perfect for a cheap Steambox.
There's a huge difference between "all wrong" and "has some fundamental assumptions that could lead to non-optimal results if you wanted to push the results even further". The former implies, upon initial reading of the headline, that whatever Wikipedia is doing doesn't even give you a better solution.

A better headline might have been "Hidden assumptions in Wikipedia's A/B testing and how it could be improved". Also, why are we picking on Wikipedia here? Don't a lot of companies claim to do A/B testing and isn't this a problem inherent in all simple A/B testing?
Tax wise BC Canada and California are about equal. BC has about %3 more sales tax, and consumer goods are more expensive for a combination of reasons. But on the other hand companies don't pay much in healthcare costs either.

The far more competitive and close by Seattle although draws in a lot of talent with no state income tax and being cheaper than California yet still close to home.

I've seen precisely one stove-top kettle in my life, here in the UK: My grandmother owned one before she died, but she spent most of her life on a farm with outdoor toilets and no electricity, and never really adapted from that mindset.

Having said that I've bought only two kettles in my life, once in 1998 when I bought my first flat and realized I didn't own one - all prior rental properties came with one - and one last year when that died.

I remember spending far too much time picking up kettles in John Lewis, and other "fancy" stores, because I knew I'd be using it multiple times a day for many years and wanted something that looked and felt nice.
Open Source and the Big Data dilemma
That might be true if they were two separate shifts... But they are not. Its one shift at two different times.

What company is going to pay for all the hassle of having two employees to cover the same shifts they can force one person to do? The hypothetical you propose is not only imaginary, but worse value on the face for the employer, and thus will not happen because it makes no sense from a business perspective.

One could also argue that any number of things, from faith in a higher power, to higher carbohydrate intake, could increase the value of an employee to their employers but that doesn't make it in any way realistic.
That's true, but the fact that you can somehow seperate the core language from the other factors ("tooling, library, schooling, existing base of people that know the language, CPU architecture, Memory constraints") is a fallacy.

Might be possible for a totally academic or greenfield small time project, but not at all if you do commercial and pragmatic oriented development, with teams, constraints, deliverables etc.

So while I agree that "that there is not as much lisp as c++ code" is not a argument that c++ is a better (core) language, I also think that this fact shows that C++ is a better language+extras for more projects.
There also other towns in France where it might be easier you know, especially regarding cost of living :) (For instance, Nantes, where I am living right now)

Ignoring the fact that the Xbox One has been selling great, isn't that more or less the point of marketing? Make a product seem popular, generate buzz, make money?
"The negatives of the split shift will drive up the per hour wages."

Wallmart employees get around 10USD an hour.

You are thinking about this as a student or someone without too many obligations.

The reality is that you need to work those other hours when you get 10USD and hour.
as much as i disagree with this approach it is actually quite fantastic to see a cross platform solution that isn't either using native code directly or Unity.

small tip: make the engine to fit a game, building an engine without a game is often a one way trip to a programmer wankfest that results in lots of code and cool tech but nothing usable

also interesting to see other approaches to the problem of games in general... this is quite high level stuff and the choice of tech has cut a lot of the implementation details out of the code (although imo still way to much in each file, but there we go) - quite different to what I normally consider 'game' or 'engine' programming - although obviously it is.

will fav and try to actually use when i get home from work. :)
I've seen this project listed before but have never used it. Can anyone with a decent amount of experience with it speak to the quality of it?
I am also pondering this problem literally right now, and working on it today. It's an issue with several of the new 'push' aka 'webhook' systems: user/key management is slim to none. Riemann server and dash setup is also cumbersome. Isn't the point of a monitoring server that I have to do less manual configuration and management?

Riemann is also a rather heavy server load just to push webhook events to a database. Requires some effort to scale. Godot (Node app that aims to be Riemann API-compatible) seems to be a better option for smaller scale operations.

Right now the solution for many CI and webhook servers is to push events to Hipchat. That does not seem to be the most reliable or efficient way to triage issues.

How are other small to midsize businesses (i.e. those without dedicated devops) managing this architecture?
I found it was useful to brush up on how the multi-armed bandit problem works in order to understand this article. http://en.wikipedia.org/wiki/Multi-armed_bandit
When I looked at Scala briefly in 2006 or so built-in support for XML processing was a big selling point. Another one was 'multiparadigm' - like C++. It was clear at that time that Scala would not become a mainstream language.
Very cool. I would like to see other utilities or tools explained in this way.

Keep up the good work!
I think his point was that $10M of apple stock was a proportionately larger portion of his holdings; had Woz kept all of his shares and donated $10M worth of stock today, he'd have far less.

But, cue the recent discussion of wealth addiction; $10M was and is enough to have a super comfortable life without working again.

Good tip, but don't forget that some people enjoy making engines and new technologies without having to make games.
There's details about the company behind it: http://baboom.com/developers/ although no word about who works there.

The design and implementation of the site are excellent, it's a shame that the discussion here focused on Kim. There's obviously very brilliant and passionate people behind the site. Possibly the same team that works on Mega.
Why don't you use an existing ontology/knowledge graph instead of building your own with thebigdb?

top 5% is a very relative description. There is no hard measure, and everyone have a different standard on what they are "measuring in their head". Our perceptions are extremely biased by our own experiences. 90% of the time I really have to get to know the candidate before making any decisions. Of course the biggest constraint is available qualified candidates at the time. That's why hiring is so hard, and people who are really good at it tend to be veterans who have been in the industry for a long time.
I'm not sure what's the licensing of what's in Freebase but I'll look into it, thanks!
Isn't it more about that the jobs that gain due to the technology are mostly in the top 1% range? I mean, the share of income going to the top 1% increases that's sure, but most of that are huge and ever growing salaries and bonuses of managers and high-end professionals - not stock dividends. If you see stock performance (at least public stocks), both in terms of cap growth and dividend yield, you see a pretty grim picture in the last 10 years compared to older times. Privately held companies are somewhat in the shadow here, but there is no big reason to think they are doing much better than public ones. Stock appreciation and dividends are what forms income of capitalists.

So it is change of the salary distribution to the top 1% (to the extent that it dilutes that said 1% of many smaller capitalists that used to be there with some ex-proletarians) from lower income groups, not shift of focus from capital to labor.

Personally all rich people i knew 10 years ago were business owners or co-owners, with addition of a few corruptioners. Now it is about even between business owners, corruptioners, and high-end professionals who don't even steal where they work. Maybe that is my personal experience/change of my contact circle, maybe a trend.

Dunno, guess some startups are shady, guess some don't. Can we please talk about Kimble now? You're derailing the topic here.
Fortunately for us, Apple acquiring NeXT instead of Be means that we get to program iOS and OS X in Objective-C instead of C++.

Maybe read the linked article to get some food for thought:

"These kinds of payments aren't inherently suspect in and of themselves. If the video makers disclosed that Microsoft was paying extra for these videos, and if they were allowed to say whatever they wanted in those videos, then the whole thing could be seen as merely an unorthodox way to increase exposure for the Xbox One on YouTube.

That's not the case, however. According to a leaked copy of the full legal agreement behind the promotion, video creators "may not say anything negative or disparaging about Machinima, Xbox One, or any of its Games" and must keep the details of the promotional agreement confidential in order to qualify for payment. In other words, to get the money, video makers have to speak positively (or at least neutrally) about the Xbox One, and they can't say they're being paid to do so."
There is a peculiar history revisionist outlook that farmers were fired and then lacking any opportunity to farm, they moved to a factory. Sometimes this happened. Usually not.

Reality, as anyone who is related to a farmer knows, farming is very hard work and a factory job is generally better.

They were upgrading, not getting downsized.

Also modern prosperity only came after labor riots where lots of people suffered intensely and died in strike violence. Obviously a lot more violence is on the way, which I think sucks. Unfortunately that seems to be the only way things actually get fixed.

History shows some really awful stuff has been done in the name of "gotta do whatcha gotta do to feed the family". So... go ahead, push a couple tens of millions of desperate people into a corner, what could possibly go wrong? I mean, its not like the US populace is extremely heavily armed, or has a cultural predisposition to consider violence as entertainment, or has what boils down to a martyr as a religious symbol...
Well first off, no one has wages denominated in BTC, it's far too unstable to do that yet. People are being paid their USD equivalent in BTC, but their salaries in still denominated in USD.

> Why would you get paid less?

Because you are not an island, when an economy suffers from deflation the prices of goods and services have to be dropped and salaries get dropped as well because that's how business works. Your employer isn't going to sell his stuff for less but keep paying you more.

> Deflation means the wage you get paid is worth more. Inflation means the wage you get paid is worth less.

Yes, I know what the words mean. But the effects of inflation and deflation are far more complicated than just the meaning of the words.

I've heard Google has a special process, unfortunately even if they make it public, it would only help startups in a very limited scope. The hiring requires are different, especially when it comes to a lot of the "soft skills".

The Four Horsemen of Writer’s Block
How can I pivot my startup?
http://easyendorse.com

It's a SaaS app that lets a site collect/display testimonials.

I developed it from scratch a few years ago and pay for everything out of pocket, so it's easy for me to hack on, but hard to market.

I should have realized this as I was developing it, but my target market is essentially small business owners who dislike Yelp.. which are extremely hard to market a tech product to. I've considered building an affiliate system in and marketing toward freelancers, but I'm not really sure how to gauge interest in that.

My gut feeling is that I've developed a nice product that completely misses the mark.

Any thoughts?

Edit: To be clear, I have no paying customers and very little traffic.

How has AirBnb have any relation to Kim Dotcom.

How does another company in tech spamming, have anything to do with whether it's morally right or wrong with another company using such tactics?

Two wrong don't make a right..
I doubt Broadwell will have any performance improvements over Haswell at the same price points. You're probably better off buying a cheaper Haswell then if you want a cheap Steambox. Intel has pretty much given up on improving overall performance of its chips. IVB was only 10 percent improvement over SNB, and Haswell only 5 percent over IVB, and the difference in price between new-gen and last-gen is probably more like 30 percent.
Mentioned one other place here, but I'm running class called Contextual Electronics. You can choose your level of involvement. It covers PCB design and electronics design principles, leading up to building this: contextualelectronics.com/the-benchbudee/

So I suppose it depends about your definition of prototyping. If you want to do breadboarding stuff, a lot of the other suggestions on here are good: start with Fritzing -> Get an Arduino -> check out the tutorials from Adafruit/Sparkfun -> Dig in more with EEVblog and AfroTechMods

But then after that, if you want to design/build your own hardware, I recommend my program (duh) or checking out other PCB type stuff from Jeremy Blum using EAGLE (http://www.youtube.com/playlist?list=PL2419BD818ADB11E1) or Fedevel academy (http://www.fedevel.com/)

Good luck!
I don't follow the connection between your comments.

XML Support as selling Point + Multiparadigm == !mainstream?

I agree that scala has its quirks (IMO, the type system is way too complicated), but to have dismissed it based on two apparently unrelated features 8 years ago seems a little strange.
Kinda but it's mostly bad drug experience, whereas The Hangover encompass any substance (especially alcohol).

It's an unimaginative 'translation', making it sound more fancy than the literal french equivalent ("La cuite").

I feel like this comment makes it sound like we care more about the shootout benchmarks than we actually do.
yes, because none of them are french!! they are iranian :D, if you want I can tell you the meaning of both ;)
> Once those "just wanna drink a beer" people have their jobs automated away, they will never again have money to participate in the economy again.

This is the whole topic of this article. The economy is broken wrt. progress and needs to be fixed. Two pillars of our economic system - scarcity and endless growth - are both being destroyed as we speak.
Not to forget that you don't always know you have cancer. So you might cut into your time where it's still easily treatable.

Do you have an example of that happening where the "free goods" were not a temporary review unit which was later returned?
Because I believe the knowledge graph of Freebase is way heavier than what's needed, and unless you know exactly the type of what you're looking for, it would make a software like Akiva way more complicated to build, imho. (or I missed something)

Emh, have you... done the calculation? Because I did. And I've found 71% for a scenario of 70k€.

It's insulting to assume I've just been adding up percentages. And when I find 71%, it's enough to back my statement that we're plainly choking our companies.

Real world applications for AI?
Can anyone share their experiences with using AI (I'm thinking approaches presented in "AI: A Modern Approach" by Russell and Norvig) outside academia?

Except for the obvious case of NLP, I'm affraid that the, admittedly fascinating, stuff presented in the book can be hard to use in practice due to difficulties in assembling the "body of knowledge" (as a belief network, or first order logic predicates) for a given domain.

Compared to the thriving fields of NLP or CV (Computer Vision), these more abstract approaches seem (at least to an outsider) to be lagging behind in industry adoption.
