It's not infeasible, obviously you could ray trace a fairly simple scene in real time with modest hardware. The question is, can ray tracing ever produce a better result than rasterization in the same amount of time? The answer at the moment is no, and probably will be for the foreseeable future. Even in high end film work, ray tracing is used sparingly where needed.
For the record, "apt-get install apache2-mpm-event" is all you need to switch to mpm_event: I believe it isn't supported on all platforms, and, as a conservative Debian-based distribution using apt-get, I'd prefer "predictable behavior across all of our targets" over "highest performance configuration on any given system".

(I also believe there are some corner cases where mpm_event may burn you on 2.2, and both Apache and Debian are going to play it safe there; but, when I looked into this in detail a forever or so ago, I determined that whatever issues they were didn't apply to my setup. As an example: if SSL were an issue, I doubt I would ever use Apache to directly serve SSL anyway, as that's what SSL accelerators are for.)

That said, I still wouldn't leave the defaults in place with regards to "number of servers / threads"; although it isn't like nginx doesn't need the same configuration: the default value of worker_{processes,connections} is almost certainly inappropriate for your specific setup. I also use nginx (as a load balancer), and I have those values at 64/10096, up from the Debian-default of 1/1024.

The important thing, to me, is what a technology makes possible, not how well it is configured out of the box. Example: it is more damning to me that nginx only does HTTP/1.0 to upstream servers it is proxying for, a reasonably fundamental limitation of the codebase, than any transgression they could make in their default configuration.

Seriously: production is not about "out of the box", it never was, and it likely is never going to be. If you are trying to run a production server using "out of the box" defaults you are going to be forever disappointed by the performance and functionality of the offerings.

To make a minor modification to a statement I've made before (http://news.ycombinator.com/item?id=2145967 is the reference) about database servers:

We (as a civilization) simply do not have the science and theory yet to make the practicalities of setting up and maintaining anything at this level of complexity a totally seamless and simple process with well-understood performance characteristics unless you constrain absolutely every single variable.
I think you've nailed it. I program a lot of JS. I don't especially like it. CS is trivially better because it is prettier but CS code expresses ideas in much the same way JS does. Big deal.

In 10,20 years people around the world may ask the europeans how they got such a rather high privacy standard. While I don't agree to all of the regulations, the tendency here is to make everything private by default and only disclose what is needed. We should be able do decide ourself what to disclose without having to install add-ons to block everything.

That said: I also use tracking, but anonymize as soon as possible. And: there are enough laws that contradict regulations like these (such as the goverments force the ISPs to store the communication data from the users).

>On-Topic: Anything that good hackers would find interesting. That includes more than hacking and startups. If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual curiosity.

Lots of hackers eat In-N-Out, the 'secret menu' is something that's pretty interesting. I learned something out of this, and while it wasn't entirely highbrow or technically complex, I'm still glad it was posted to HN.
We are looking to bring together hackers, where-ever they are. Not just the ones who have a hackerspace nearby.
I've found it to be true that In-n-Out isn't that good on an absolute scale, but it's great for how cheap it is. I can definitely get a better grass fed beef hamburger for $10 (or an even better one made from the ground lamb at the Berkeley Bowl for $8.99/pound) but haven't had a better fast food burger than In-n-Out.
Web Sites Should Not Be Replaced by Facebook Pages
It's amazing how I'm on the same situation. Actually it's if you think it's not that amazing, I bet like us there are loads of people trying o do the same thing.

The questions that crosses my mind are:

Should we do everything by ourselves or should we try to find partership?

I have been looking for partnership but it's very complicated. Everyone has it's own ideas and no one wants to be part on someone's else idea. I still couldn't figure out a way to solve this. Maybe it's even an insight for an idea.

What I'm doing is trying to learn to do by myself. I'm taking the easy path, using frameworks and everything that helps.

At the moment I'm trying to put my ideas together with: jquery, wordpress, some PHP basically for the wordpress integration and hacks, and APIs. And I'm aware I should start with some server side. I would go for the RoR.

Just sharing my toughts here. I'd appreciate any comment on that.

Ecommerce Shopping Cart and Custom Checkout
The shopping cart software helps to keep track of numerous orders, and it allows us to see everything a buyer ordered at one time. In many cases, a custom shopping cart is connected to online inventory so that a seller knows if he has enough of the product to fulfill his orders. It also enables him to extract what consumers have paid for and hence know what may benefit a customer for the future.
That response misses the key advantage of Type-Ahead Find (which I guess I didn't make clear in my question) that pressing tab moves the focus to the next link in the text flow, and pressing Enter (Ctrl-Enter) opens the link (in a new window with Ctrl-Enter.) It's a much faster way to browse, because it completely eliminates mousing.
I've spent a good chunk of time modifying an image labeling interface to make it more intuitive for mechanical turk workers to label obscure things like biological scans. The hope is that a better interface will increase quality (they did not seem to have a clue what to do using the old interface), but I'm starting to question whether the interface will make that much of a difference after all.

Don’t Charlie Sheen Your SEO
Why not do a version just for people's pets?

Maybe try and surface potential models?

Otherwise, why would I go there?
It's fun (and a valuable experience) to pitch. But in some ways, people sometimes get more out of the 54 hours when there's none of the emotional pre-attachment to your own idea, and none of the resistance to flexing it with insights from the team and the mentors.
The article raises an interesting point: that many turkers just assume there is no quality assurance being done on the requester end and everything will automatically be accepted and paid for. Since it is tricky to automate QA for huge sets of tasks I would guess this assumption is mostly correct, and turkers take advantage of it.
These guys are awesome—they power all our payments. The one thing I wish they could somehow add support for is outgoing EFT/ACH transfers.

We do have one funny story about them from Getaround... one night, early in the morning, we got a call directly from their CEO. Apparently we had written some bad code that was just hammering their servers—basically, we were accidentally DoSing Braintree.

Got it fixed up quickly, and have loved them and used them ever since!

If you are trying to run a production server using "out of the box" defaults you are going to be forever disappointed by the performance and functionality of the offerings.

I have sold hundreds of thousands of dollars of software to thousands of people which has run for years without (web-server related) incident on nginx. If I am fated to be struck down for my ignorance of nginx internals, that doom must be further down the road.

Where I do see failure is when I put the world's most popular blogging software on Apache, turn on caching and give it a gig of RAM to play with, and then watch the server get denial-of-serviced by the totally innocent actions of any ten readers attempting to access the website in a 15 second interval. Thank you, KeepAlive. Ten is not a big number on the Internet. Apache has been DOSed by my younger brother's comic book writing advice blog.

I accept that, for historical reasons, the Apache project does not optimize for being useful without being a master of arcane trivia like knowing what options the server is compiled with (!) to be able to operate a college student's blog (!!) without falling off the Internet. Much software developed these days pitched at web developers, including software which I write, has as a guiding design principle that you should be able to start using it in five minutes following simple instructions and those sensible defaults should mostly work. I think this development model is categorically better than software-by-the-experts, software-for-the-experts models.

P.S. apt-get mysql gets you a database which won't fall over if you try to host a comic book blog on it.

The way I see it: working hard + branding = success
An open letter to Rob Cockerham
As numerous commenters have noted, this article twists/omits facts, blows things out of proportion, and doesn't talk about the benefit to consumers.

Tracking is currently a hot topic in the US as well, where a different approach, labeled Do Not Track is being pursued. I happen to be at the thick of it, so I thought I'd add that to the discussion.

Do Not Track (http://donottrack.us/) is fundamentally an opt-out from tracking rather then an opt-in, which makes it much harder to claim that it will threaten the ad industry, startups, puppies, or anything else [1]. It is an HTTP header which, if enabled, signals to advertisers and other trackers to stop tracking you across multiple third-party websites. First-party tracking is OK.

The Do Not Track option has already been implemented in Firefox 4. As of yesterday it is an Internet-Draft[2], and on the legislation side, Congresswoman Speier recently introduced a bill to give the Federal Trade Commission powers to enforce Do Not Track.[3]

I'm a computer scientist and this is my first major foray into the policy arena, and having worked with most of the people/entities involved in this effort, I have to say I've been pleasantly surprised how the disparate parts of the technology/policy/regulatory machinery started to work together.

I don't want to get into which approach is better, but just wanted to describe how we're doing it in the US. Feedback welcome.

In Brazil, it was translated as "Google Perfis". Bad bad bad. Facebook is a single brand across all countries. Google should keep a single brand as well, even "Google Profiles" would be better than "Google Profiles" translated in every language possible.
jotform.com is close to what you're looking for.. You get more entries but not 10x more. And their 'almost unlimited' version is only $50/month.

Note that they also license their engine for surprisingly cheap (IIRC $250), so you could run it on your own server if you really wanted to.
This is astonishing. XFS is from 1994...
Even worse nightmare is pretending that the code is more stable just by labeling it as "package vX.Y.Z" and hiding the actual meat behind such "profesionally" looking cortain.

And yes, I'm an admin for 15 years.

My experience is when software is bad, it's just bad. No packaging system will help it. If I have a suspicion it's bad, I want to see quickly just how bad it is and check if I can repair it in half of an hour or drop entirely. Github helps with such decision greatly.
XFS had a different use case. Pull the plug on XFS and you have problems.
What you typically do is include gold data in your dataset. I.e., define a HIT to be 10 sequential tasks, 3-4 of which you know the correct answer to. If a turker can't get the gold data right, their work is rejected.
In Haskell, foldr can sometimes produce output as soon as it sees the first cons. So you don't have to wait for the whole list, which may be infinite.
Until someone uses mturk to spam your ratings.
I presumed tracking meant cookies which were used outside of one website. Good point.
Yes. Or depending on what kind of result your fold should produce, you may be better server with foldr, which actually benefits from lazyness.

SEO is only 'bad' if the particular optimizations you make are targetted by search engines for de-prioritization. You can't know what is 'good' and 'bad' SEO for the future. Heck, Google won't even say how they calculate it no one really knows.

Also, if quick press getting hits are bad, then why would you write an SEO article about Charlie Sheen? Surely the 'white hat' practice would have been to leave Charlie Sheen and his antics out of it.

And yes, the system uses very, very little power compared to the lights. My light dimmer uses ~4 watts when off, while each single bulb uses 100 (still waiting for dimmable fluorescents to be able to dim smoothly to zero). I've measured the Kinect at ~4W as well. One thing to keep in mind with home automation is that, yes, it usually does save power, but that's not why you do it -- it's about saving time.

I am really interested to know. Right now I am running EXT4 on an SSD in my notebook. It performs well.
Sometimes, after a suspend , I get a load of EXT4 error messages which are stalling the whole notebook. Hard resseting it, makes the error disappear. Up to now, no data loss.But anyway, this makes me a nervous and I am not sure if it is due to Kernel, SSD, Ext4 or the combination of all/any of them.
I guess XFS is way out of my use point, but anyway, an option is an option.

I'm usually not a proponent of EU regulations, but i don't think telling customers the truth should be considered harmful by any serious entrepreneurs.

Customers will probably be scared at first, but once they understand a bit more about tracking (which are harmful, which are not), opt-in system will definitely add to customer's confidence, and thus benefit to business in the long term.
The second variant is correct, indeed, as the sex of experts shifts (changes) from the male domain to more and more female experts.
Ethics are murky. Don't talk about things like this on public forums. Google's watchful AI is always with us and when it finds you it will crush you. In practice, why hire people to rate it 5 stars when you can pay 200 friends of your friends to download your app and rate it if they like it?
An even better (and common) strategy is to reject the work that fails the gold-data test and to reject most of the rest of the work too, claiming it failed the gold-data test.

Couple of small issues. You probably want "when" instead of "if". The if applies to the whole loop, not to each element. Also, the braces around the comprehension is a pythonism I guess? It means it puts the result into an array, so you get [[<stuff>]] instead of just [<stuff>]. I've made that same mistake a bunch of times.

Nitpicking aside, I totally agree about the expressiveness. I find myself writing about half the number of lines in CS as compared to JS, and the syntax fits my brain better.

No, it's intentional.
Yes, this is a far better solution.

It also gives flexibility back to site owners. If you business model depends on tracking (so much that a visitor who opts out of tracking costs you money) they are free to redirect the user away or throw up a paywall.
