I'm guessing that you're American, and that the author is not. My understanding is that in most of the English-speaking world, the game is called "Chinese whispers" (although that name is falling out of favor because racism), while in America, it is usually called "telephone" or some variation on that.
There is an observed situation in evolutionary ecology which the response to Lennart rather reminds me of: the case of the overwhelming singular adaptive advantage. An ecological situation arises which gives one subspecies a huge, but temporary, advantage. So huge that all the other subspecies are competed to extinction. But that advantage was an advantage in only one aspect of survival and now there's a monoculture (which we all know is more fragile against future threats). If there's a latent, (or perhaps overt?), Lennart-phobia, it's that he possesses that one temporary huge advantage which will lead us to a monoculture? ...or not, this is just a curious analogy [shrug]

Maybe it's not uncommon, but it is against FTC guidelines. (I claim that because it's in the article too)

I don't know if being "against FTC guidelines" is equivalent to "illegal" or not. But let's hope so.

Most of the $25k donation was from a single, large owner of Dogecoin. Flagged for being little more than shameless pumping of a "joke" (tee hee!) currency. (disclaimer: I own some Dogecoin to hedge my sheer annoyance with it against the money I'm making from its absurd success).

I won't comment on the virtues of bandit algorithms, but the author grossly mischaracterizes the requirements of a multivariate A/B test. Just do a regular 50/50 split and run a regression on the outcome using the observable characteristics as explanatory variables. Then take that model and feed the observables back in to get an individualized prediction as to whether A or B will perform better. You can bin continuous variables or you can including higher-order terms to achieve a polynomial fit. The data requirements really aren't that large.

I believe the author's confusion stems from attempting to model every interaction term, e.g. if you think there will be some extra effect to being Male and using Windows and being Swedish that is more than the "Male effect" and "Windows effect" and the "Sweden effect" considered individually.

I wrote a little article on implementing a simple multivariate A/B test from scratch:

http://www.evanmiller.org/linear-regression-for-fun-and-prof...

All you really need is a function that inverts a matrix and you're good to go. The cool part is that you can actually throw away most of the data that comes in from the firehose, just keep updating the Hessian until you're ready to invert it and bam, you have a model.
I think that you and jerf are talking different languages. You're saying that, economically, this makes perfect sense. And you're right.

But jerf is saying that, in Darwinist terms, this makes no sense at all. And he's also right.
No sweeping generalisation: I simply wrote that academic executives react badly (all of them) to senior teachers (some of them) having a break-down after reading poorly written and spiteful reviews (no matter how few of them there are, and there always are some in a campus the size of Yale).

> Some teachers ARE lousy.

Very much so — I am one, and I’ve always told that most of my teachers at my school were criminally bad. (I did take steps to have some of them sent to jail.) I do not remember arguing the opposite.
Thanks for the clarification. IIRC you are a co-author of the paper, so perhaps you can answer a follow-up question.

What kind of latency or CPU usage change should a typical modern SSD on an amd64 class multicore processor observe when using the new block layer?

Also correct me if I'm wrong but since Linux aggressively caches already and SSDs are already way faster than older drives for normal (ie. ~random access) loads, plus RAM is cheap and plentiful these days, I am guessing that very few applications will honestly be IO-bound enough to see that benefit.
Groklaw had a clear bias and that could be corrected for. Their clear explanation of legal minutiae such that even a layman could understand it, and their attention to detail is why I follower their coverage.

If I was freelancing, I would indeed spin on a dime and change to SASS, but in an enterprise setting, we can't change all our structures to use LESS. Well, we could. But it takes some time, and time is money, right? I'm happy enough with LESS as it is.

It's also not "they", as it's been developed by a single programmer. Certainly, Bellard is no ordinary programmer, but this should still give some perspective to your claim of the millions of dollars required for development.
A lot of the pictures up there are ones I've taken. There are others that I've pulled from flickr (after first getting permission from the photographer), for example, the landscape on http://hike.io/hikes/mount-meru, is from a flickr user.

I'd agree with your two and add two of my own:

1) The existence of the middle class

2) The general public gets to participate in commodity markets. Not the trading commodity market, but the consumer markets. No more buying food, medical care, housing, clothing, no longer participants in the system. The monetary economy is for other people, the rich, not everyone or even the majority.
I've been playing with Cython recently and I'm really impressed with its compatibility with arbitrary Python code. It's possible to compile all of Tornado with only minor changes (for a ~25% speedup without any type annotations).
https://groups.google.com/forum/#!topic/python-tornado/Kele7...
Great example, and I’m assuming that “aggressive moderation” was something that guaranteed its existence, and was what Yale wanted to see confirmed before letting another similar effort grow.
Right. Do not forget a small clutch of community-approved and government-tolerated exchange businesses forming a second circle of effective monopoly.
I used to do contract programming, and worked with a few businesses who expressed issues with external review websites, but I have a hard time jumping from that topic to selling my product.

I unfortunately do not have any paying customers, nor much traffic in general.

"and find ways to reach out to them" do you mean lots of cold-calling?
Does anyone else feel like the only reason to choose systemd is the systemd-journal? That thing is just amazing. The amount of leverage provided by not just appending to a log file somewhere will really get the juices moving in anyone who ever had to write some ad-hoc parser to do the same thing poorly.

If anyone hasn't tried out systemd or journalctl yet, I suggest running a copy of Arch Linux in a virtual machine.

That's interesting, I'm surprised ASA are so lenient given that product placement isn't even allowed on UK tv. (Although they are phasing it in).
It was version 0.11.1 & 5yrs back, and I was in undergrad college.
We used to hack on the cython code all night. :)

I got very Poor Grades that whole term.

And I can't forget those days, we used to hack all night on cython code but missing very important college lectures!

I did not even know how to commit!

But, It was pure thrill. Those were the days, I badly miss today!

And surprisingly I also fixed a very critical bug, that was the very first bug I had fixed in my Life.
I started to realize, valuate & appreciate Open source & the reach of OSS!

cython changed my perception about software!

That marked my entry into OSS, and I was writing & optimizing for good code with standards and all the documentation. Until then I couldn't appreciate anything much of OSS.

* I literally danced around after I submitted that bug, and incidentally it got approved and committed too! :D

And it was the very early days of Cython Project <ver 0.11>

http://trac.cython.org/cython_trac/ticket/203

And today when I checked Cython Project,
I feel awesome within, all around my body; esp the way Cython has grown & is being consumed across!

Power of OSS!

We should be honoring and celebrating every project out there that has done so much to Humanity!
Hi, this is awesome!

Hopefully useful feedback: when I saw that, I immediately thought "what are some nice hikes around where I live?" and even though the tagline is "Find beautiful hikes", the homepage doesn't suggest that I can find the answer here. Maybe that's not the point of hike.io, maybe there's another website that would help me better, I don't know.

Anyway, the big picture of the Narrows, which is one of the very few hikes I've done, inspired me to look for new trails around where I live. Thanks for that!

And good luck, I can't wait to see how hike.io will grow!
I'm not sure I buy into low/high skilled work idea. As an active farmer and software developer, I can say that farming is the one that requires more creativity and cognitive load of the two, yet is the one in decline as far as jobs go.

What is interesting is the market demand differences. When farmers invented tools to multiply their output, the demand for food changed very little. Soon, a small group of people were able to fill the needs of the world. When software developers invented tools to multiply their output, people wanted even more software to be written. We're still trying to catch up to the demand, even though we're producing more software than ever.
A tangential thought: if there was a guaranteed basic income, I suppose they could do away with minimum wage? This would open the possibility that some companies could pay less, but would have to compensate by making their employees really happy, otherwise they'd just go back to the basic income.
Systemd is a decent init system, fast (ssd+systemd=10 sec from button press), and dependency resolution is quite good. The units are configurable in the /etc/systemd directory and take precedence over the (/usr)/lib/systemd units. It is not perfect but it works. I believe it is somewhat better that sysvinit especially in dependencies. You just need an After=foo.service or Wants=foo.service and systemd takes care of everything. I know this is supported by sysvinit but the whole numbering thing always seemed like a hack to me. Systemd gets it right.

That being said, I can't say I am a fan of the integration of other services within systemd, it seems somewhat bloated. And I certainly don't like the whole journal thing. When the journal becomes bigger it becomes considerably slower. And I don't get the point for binary logs. I mean, logs are just text, why overcomplicate things?

I've been using it for over a year in Arch it is really good as an init daemon, I believe it is definitely a step to the right direction especially for desktops/workstations, probably for mobile as well. The rest of the package though, I am not so sure.
Always useful to see attack vectors. Nice well written blog post.
Incorrect, advocates of the free market don't even think there's anything wrong with this, including myself.

This is on the level of finding out Santa Clause isn't real and politicians are generally liars.
>All of this adds up to a massive bias on my part

And yet it's so subtle, I wouldn't have noticed had you not pointed it out.
>"One could also argue that any number of things"

It is not unreasonable of me to think that increased employee availability will lead to increased number of hours worked. Whenever it becomes easier for me to get something I want, I usually get more of it (e.g. Netflix); there is no reason to believe labor is different.
I don't know what the big deal about Apple being the "largest company in the world" is. Who was the company that they passed. Exxon Mobile? Shell? They create great products used by billions around the world. No one romanticizes their CEOs, and they're all assholes too.
Man, I agree with fanatical, and you'd think that would be enough.

But just look at Gruber. While I still bothered to click the occasional Gruber link-bait I seem to recall he on several occasions mentioned equipment which he "had gotten from Apple". I'm assuming that means he didn't pay.

I'm sure I say stuff like that loads of places. Especially on the hipster SF blogs which for a period made this website almost unreadable.
If you read my comment slowly, you'll notice that I do not rate teachers in absolute terms, or on a scale at all — I actually hate that (and, yes, I have grave concerns with your “2%” or “90%” because of that). What I did write was that some teachers, no matter how great, come with details (unmeasurable in most cases) that are problematic: their accent is the most common one; details that can be easily fixed (ask Pigmalion), but that rely on intelligent feedback. No numbers. I don't like numbers.

It's worse when you realise that the millions freed from the land mostly had to choose between working insane hours (often dying from stress alone), or dying of cold or starvation.

Better paying jobs only started to appear a generation later, and only become really common at the XX century.
Server hardware init is also a problem, the Coreboot project started because of that (IIRC one admin mentioned something in ~hour for a cluster).
If only Hacker News was written in Cython, rather than the crappy current implementation. Does YC invest so much money they cannot afford a second server, or decent programmers?

Still, quite an achievement, for something to suck and blow at the same time!
What sort of response do you think I should be looking for from cold calling? Any time I hear stats like "only 1-3% of calls will lead anywhere" it seems like a massive time-sink. But maybe that's unavoidable?
And... it just called in. A bit late - everyone was getting nervous.
Hey there, I wrote that post. It's a valid criticism you make, but the main point of the article was not to pick on Wikipedia, which is actually way ahead of most other organizations in terms of testing its content.

We made a case-study Wikipedia because their banners are a well-known example of A/B testing. Plus, because their banners make tens of millions of dollars each year, and they have an entire team of people working on the A/B tests over a period of months, I think they have capacity to use something more sophisticated. Maybe, like you suggest, they're just focused on other aspects of the fundraising campaign. I guess the only way to know would be to hear from some of the Wikipedia team!
Actually it's been allowed since 3 years ago (early 2011), except on BBC channels due to their publicly-funded status. There are Ofcom regulations which need to be complied with, which includes preventing it in certain program types (news, children's TV, etc.) I don't work with TV much so I don't have full details on the tip of my tongue, but anyone interested will find it somewhere within The Ofcom Broadcasting Code [1]

Not exactly. It does do stuff concurrently, but not always in "parallel" since it may only have 1 core available or not get scheduled across multiple cores. I disagree with that particular wording of the systemd description because it perpetuates the concurrency == parallelism misunderstanding. Not that I don't like systemd, I've been using it for over a year and haven't had any issues, and its concurrent model does seem to improve boot times somewhat and there's no more figuring out how to order your daemons since it handles that for you.
Sure did. I mentioned it in the other thread.

The compiler is pure magic. It does all sorts of strange and mysterious optimizations, I have no idea how it works but it seems to work very well.
Not sure how this applies. I assume you automate some things that you could simply type in by hand every single time, why not this?

My girlfriend studied in Poland. Her experience describes the polar opposite of all the anecdotes I heard from most American universities: extremely strict teachers, highly hierarchical relations, vastly more demanding personal work. In such a context, especially if it's espoused by students, I’m assuming that such a feedback community could work with minimal external control.

I strongly doubt that with the ratio of entitled students in the US, and the authority they wage over other students, this would be nearly as functional there.
I'm a cofounder of the early 2-person startup whose blog post this is.

Yes, it's currently difficult and expensive to bring complex ML to bear on this problem; we are trying to make that easy and cheap. The reason people adopted AB-testing was that it has a positive impact on the metrics they care about; we think the workflow can be easier and more valuable than AB testing. If its easy to use, the extra value should cover the cost.

We're currently focused on trying to communicate that this approach can create value - this blog post, written for a technical audience, is to give some intuition around how the approach works - does that make sense?

We genuinely believe in making it easy to use ML optimisation in this context - that's why we're working on this.
Hi, I’m the creator of prerender.io.

Last time someone posted prerender.io on HN, I totally wasn’t ready. We only had the open source component. Launch early, right? Now, we’re a full blown SaaS solution for rendering HTML to crawlers from SPAs or AJAX heavy websites.

Our open source prerender server has improved a lot. We fully support _escaped_fragment_ and only check user agents for the crawlers that don’t support it. The server starts a pool of phantomjs processes, has a robust plugin architecture, can be installed via npm, and easily customized like expressjs.
Fair enough, I unflagged the story. My annoyance probably stems from all the dogecoin fans calling it a "joke" currency to mask their greed. It was a joke currency two months ago. Now it's a liquid, $MM cryptocurrency second to Bitcoin.
Is there an opportunity to use this to build on a dataset like Open Street Maps? I don't know much about that space, but it seems to me that your users will either be consuming hiking trail maps, or generating them. If they are generating them it'd be awesome if there were a way to contribute the data to some copyleft source. Assuming that's something you're willing to do.

Admittedly, Google Maps is much prettier than I remember.
It might help to define the salient term here, "derp". In July 2013, Krugman defined "derp" [0]:

People who take a position and refuse to alter that position no matter how
strongly the evidence refutes it, who continue to insist that they have
The Truth despite being wrong again and again.

Krugman has indefatigably chronicled the failure of libertarian principles to predict outcomes in the real world. Here are a couple examples of spectacular failures in recent years.

* Predictions that the Federal Reserve's bond-buying program would result in double-digit inflation (or worse, Weimar-style hyperinflation), but then failing to change their views as the inflation rate hit historic lows.

* Claims that the rising price of gold indicates "true" inflation, but then continuing to rail about inflation as the gold price declines 36% from its highs.

Similar themes of sound money, the gold standard and Austrian economics are featured prominently in DPR's writings [1].

Krugman considers these to be "Zombie ideas" [2] that have been refuted by real-world experience, yet they continue to shamble forward. Hence, "derp".

guys, you're way past version 1.0 in most users' minds, might as well consider dropping the 0.
The post linked describes quite well an example situation systemd solves, and why something like systemd is needed. Perhaps you should look at it.

13 illustrated articles on how I built an HTML5 game from scratch
For context, the full title is: "Cyber attack that sent 750k malicious emails traced to hacked refrigerator, TVs and home routers"

And yes, "refrigerator" is (only known to be) singular.
If the purpose of the site is to find new hikes, presumably we don't already know the name of the hike we want :)

What I expected was a location-based thing: show me hikes near where I live. I would find that tremendously useful.

Good start!
Hi, I'm the autor. I spent 9 months building a game with my team, and 3 months writing 13 articles about it.

The game and tools were made in HTML5 and javascript from scratch. If you're curious how it was developed, you might appreciate the detailed and organized account of how it all happened.
I haven't seen Brunch before, but it still seems to suffer from the same major flaw as Grunt, which is no sense of file-file relationships:

"Brunch recompiles and concats all your stuff automatically on any change, headlessly. No more need in compicated Makefiles and watchers."

Perhaps I'm wrong, but Brunch just seems like a variant on Grunt with a lot more out of the box for building front-end web applications.

Still, it does look cool. Thanks for the link!
Many such websites don't really expect that, and present teachers by averages of all grades, unweighted by how articulate the review actually was.

I have seen such websites rare last (and publicly shame) very demanding, very good at that level of teaching, socially awkward teachers — in a way so aggressive that can only de described as late-in-life bullying. I was part of a group of students who personally intervened to avoid a suicide.
Pretty cool! Does it track dependencies of build steps that have "require"? E.g. if I have a javascript bundle being built using browserify - will it track the files that browserify is loading? Also: Did you consider reusing the Grunt ecosystem? E.g. enable loading grunt plugins and treat this as a potential alternate runner?
I've not found coffee makers terribly convenient for making tea.
Up until this debate, I don't think most people were aware that there was even an init-culture to fear turning into a monoculture :)

I think your observation is true though.
