>Q: Can the device be mounted in any orientation?

>A: Yes—the air bearing assembly is held together by magnetic attraction (between the stator and permanent-magnet rotor).

Exactly, just came here to say that. Heroku has some serious cash and resources post-Salesforce.com acquisition, seems like they should prioritize redundancy across another provider or whatever datacenter(s) Sfdc are using.
"I’ve had visitors buy all sorts of expensive and odd items when they left my site to check out a $10 book on Amazon. And trust me, pink vibrators can add up quickly."

I am mostly in the dark on how this program works, does this mean the Amazon Associates Affiliate Program allows the referrer to see exactly what the people who click through their link purchase within the next 24 hours?

I assume it would be anonymous, and I guess it makes sense to understand the demographic of your site, but it certainly seems a bit invasive if clicking on a referral link tells that blogger your Amazon purchase history for 24h...
Goodrich ISR sensor equipment has been able to do this for a while regardless of the type of plastic for the purpose of quality control in product containers:

http://www.sensorsinc.com/image_powderswirenlarge.html ... "While a visible camera cannot see through plastics, these same plastics are transparent with the short wave infrared. Goodrich ISR-P cameras can see through plastic to detect the fill level of a product. This capability is extremely helpful in quality control and process control applications."
As a Sonic.net customer for the past 7 years and a friend of Jake's, I applaud their efforts to not keep logs. That said, I'm curious what logs they are talking about.
I understand that: index.html is just one possible name for the "default page" filename. IMO its perfectly valid (if redundant) to specify it explicitly in a url. I still don't understand why this was described (not by you) as unacceptable.
Replacing Founders with CEOs
i think this article lost a lot of merit because 130hrs/week were mentioned. i am guessing this was some kind of record and happened once, but because of the way it was mentioned (proudly, to illustrate that she's a badass) the article seems to insinuate this amount of hours could be sustainable, and worked around with a few anti-burnout tricks.

if this advice was given for ~60hr weeks, it would actually be a lot more credible.
First of all, I'm using Linux and it opened on Firefox instead of Chromium.

Secondly, it seemed quite slow, and I can't use Ctrl+Shift+Up to select a paragraph above and Ctrl+Shift+Down to do the same to the paragraph below, like on Emacs.

Either way, the live interpretation of Clojure code looks really great, keep on working and good luck!
Really? I thought the font for "Scrolls" and the art up the top look a bit amateurish. Presumably well in line with the aesthetic of the game, but not worthy of any kind of positive commentary.

Hard drive bearings are big and expensive!

But the heads are mostly kept above the surface by aerodynamic effects - effectively they are held in a thin air film which stops them touching the platter.
Many of our programmers and writers agree. We're an advertising-based business (free online news) so I view this as one consequence of that

A small chunk of these are due to social and other 3rd party features, a good chunk plain old analytics tracking, and another small chunk are due to our "brand lift" advertising guarantees (e.g. in some cases its ensured that readers are actually seeing your below-the-fold advertisements before we charge you for them).

That said, yes, more than a few Ghostery hits are so we can, e.g., buy an ad to reach Forbes readers when you're visiting Adweek.com or something. Ghostery is great and a useful instruction tool for showing the "boiling frog" that is pixels.

Their data suggests that the air gap provides minimal resistance to the flow of heat. As for the clearance, they've stated that unusually high-precision manufacturing is not required for the two surfaces.
That's a terrible straw man. Everything changes. Javascript is morphing into this weird "Coffee" thing before our eyes. Python pushed a completely new language and is currently supporting two of them. Even python 2.6 looks absolutely nothing like 2.0. People fled whole-hog from perl and python to ruby (another hardly static language) a few years ago, and most of those same people are now retraining their brains on that JavaCoffee thing I mentioned.

C++? Yeah, brand new version out with whole new metaphors (An... rvalue reference?! And what is that -> operator doing there?).

If you want compatibility, you have it. 15 year old perl scripts run fine on 5.14. If you want the community to not invent new stuff... dig yourself a hole I guess.
SCOTT HORTON—Obama’s Kill List
Make sure you at least got this points correct when trying to upgrade:

1. require('sys') throws, use require('util') now. The "sys" module was deprecated in node v0.4.

2.cluster.fork() no longer return a child_process.fork() object use cluster.fork().process to get the object.

3.the 'death' event on the cluster object is renamed to 'exit'
Upgrading old authentication to new Devise
It works perfectly on mac. Great work Chris, this demo gave me a sense of an Apple product "it just works", i typed in code and immediately it just worked.
Not to mention that an out of the box .NET/CLR will just run fairly well. An out of the box JVM may or may choke, depending on the app you're trying to deploy. I've spent so much time trying to tune our JVMs for performance, that sometimes it's nice just to deploy a C# app on the CLR and have it just "work".

No, in the context we are discussing, a PC is not a "personal computer", but what was called an "IBM PC compatible" (and subsequently by some a Wintel machine).

Few people use "PC" to mean personal computers in general, especially since for 99% of the people personal computers are all they know and encounter anyway, so no need to distinguish both Mac and PCs from, say, Mainframes and embedded systems....

That's why nobody got confused by the 3 year running "-I'm a Mac, -And I am a PC" ad campaign.
Great solution. This is the right attitude toward security in any case, Mac or PC. You can't neglect safe driving just because your car has air bags, yet I see that exact problem on computers with anti-virus all the time.

Macs actually do make it easier because they have a pretty good track record of not "crying wolf" with things such as password prompts or security warnings. Most of the pop-ups are justified and infrequent.

Macs have never been 100% secure. No computer is. Apple pulling this marketing has nothing to do with a reduction in security and everything to do with covering their legal butts as their platform becomes more popular and more targeted. It's still the user's responsibility to keep themselves safe in the end, even with a decently secure OS.
In a trivialized mathworld, many calculations are useless for the real world. Trivializing the same way, we might as well ignore the capacitance of wires, cross-talk, and general EM noise and claim that wires can transfer at infinite bandwidth. Or say that air has no resistance, therefore we can launch a cannonball into orbit around the earth at roughly sea-level.

This is no different. It's pointless hyperbole.
You are probably right.

Still, why didn't they just attach a normal fan-motor and then compare that side-by-side to a standard-fan?

It always seems a little fishy when a marketing-video does anything but the obvious.
There was a slip which led to his capture. Instead of paying the unfettered price for the crimes he committed, he ratted out his friends in a blatant abuse of the system in order to lessen his punishment.

The lesson for today kids, is never commit a crime alone, so you have someone to rat out on for that plea deal!
Yes it's a radiative/convective coupling in the thin air gap.

Although the thermal conductivity of an air gap is normally low - which is why you have double glazed windows - it gets complicated if the gap is much less than the free path in the air
What are some recent examples of such Windows viruses even?

Most malware is spread by downloading fishy software or from browser/Flash/Java/PDF exploits.
I remember seeing this a year ago. It's a bit worrying that in that time they still haven't gotten around to building a prototype that will be as quiet as the claimed final product. While that doesn't mean it can't be done, it may point to deeper issues in the project such as yet unaddressed technical challenges or lack of funding (which might in turn suggest lack of investor conviction).

Personally I'm curious what the failure rate will look like with these things. Given it will probably be higher than existing PC cooling fans which are moving lighter loads, this may indeed be a problem.
3 ways to ask Google how to effectively interlink your posts
The author of this post has not stated who he spoke to. I suspect he has spoken to a random from #openindiana on irc.freenode.net, who is not actually an active developer.

The OpenIndiana developers collaborate on #oi-dev on irc.freenode.net.

Also the Solaris kernel is excellent and has features that put it ahead of the game in many areas. Take Solaris Zones, the fully virtualised network stack (crossbow), the COMSTAR SCSI (iSCSI/FCoE) target framework, the Fault Management Architecture (FMA), along with a whole host of other advantages, put it significantly ahead of the game. Also thanks to Joyent the illumos kernel supports KVM, something FreeBSD does not.

FTA: "A quick look at the output from ddms shows I was allocating tens of thousands of Colour, Vector2 and Vector3 objects per image"

And this is the fault of the garbage collector? Doing per-primitive ops by allocating heap blocks is a disaster, sorry. No one doing HPC does that. This won't run well anywhere, though obviously a desktop machine is going to give you a lot more freedom before you see frame rate problems.
I can't speak for Marissa, but I certainly did pull one or two 130-hour weeks "back in the day". They _were_ productive. I did pay a huge price for them, both in terms of reduced productivity for weeks afterwards, and in terms of health. (I always get a horrible cold after exhausting myself that much)

There are two things to keep in mind:

1) These weeks were rare. I'd expect they were rare for Marissa too. You can't do that anywhere close to regularly. And you don't. Those are heroic efforts to meet a particular deadline.

2) That was "back in the day". Late 20's, early 30's. As you get older, those efforts are much harder. (Damn it, all the old people I knew needed next to no sleep. Can I please finally be old enough for that? ;)
Irish Mailing Lists
When they call Anonymous a hacking collective, you know they're either too stupid, or too corrupt to say it like it is.

They're just a bunch of stupid kids, and I wouldn't label what Anonymous as a whole is doing as hacking regardless of how you painted it. Lulzsec on the hand...are a bunch of kids who learned TRICKS before they gained the knowledge that comes with it.

After years of learning and you get to a point of finding exploits yourself, you understand at this point WHY doing things is a bad idea.

They skipped the learning phase and just learned some stupid tricks that allowed them to do a lot of damage while knowing little.

I didn't try to participate in olympiads, but I started participating in competitions when I was 20. I practiced for ACM ICPC for 3 years, which was arguably my most enjoyable days in my life.

I stopped participating in programming competitions when I was about 24. But now I am 27 and I have started doing them again. I am not as strong as I was (or even close to it), but I am aiming to become strong again. One of my goals is to qualify to the GCJ finals next year (this year I was in Round 3, but couldn't make it to finals).

Joy of solving problems is the greatest joy I've ever experienced.

Do random accents help verify that you're handling Unicode correctly? You don't know what it's supposed to look like, so how do you know you're displaying it correctly?
In case anyone is wondering whether this reflects Google's current working culture, let me comment that in my experience it absolutely does not.

In the office I work in, it is virtually empty at 8:00 AM and mostly empty by 7:00 PM. Most people seem to show up around 9:00 AM and leave around 6:00. On Fridays, the office mostly stops working around 5:00 PM.

There is a cadre of people, typically those without families, who stay a bit later but it often seems like they stay just long enough to eat the free dinner and then head home. Those people often also show up around or after 10:00 AM.

There is variation from project to project and office to office, but the work life balance seems very healthy in the offices I've seen. I have kids and a long commute, so it's important that I don't work late and I've never felt the slightest pressure to work more hours.
Everything so far works fanatically. Awesome job.
repa also has some unfortunate lacunae, either in the API or in the documentation.

For instance, one thing I tried to do but couldn't - apply `scanl` to an array with a piece of intermediate state that is threaded through the computation, save the piece of state at the end, and then apply `scanr` to the same array, using the piece of state from the application of `scanl`.
Does someone actually need to say this is an asinine technicality that isn't relevant to the discussion?

Good.
It's funny because before I started here in Silicon Valley, I've periodically applied to many large companies that have traditional R&D. My experience in academic R&D at the DOE National Laboratories made me want to transition over.

IBM, Intel, and many others, simply ignored my application. I didn't go to a top ten school, or I didn't have "8 years experience in XYZ," so I was overlooked.

Right now I work at one of the biggest Internet companies in the world, but do you know how I got in here? Through an acquired startup. The people in my small area had the vision to see that I had skill, even though my resume didn't say Stanford or MIT.

My suggestion to you is that maybe the big traditional companies are not trying that hard to hire. Let's face it, it's going to be harder and harder to get grads from the top schools as long as they're getting millions in funding from VCs.
Just as much as the game itself, and patches to it. Nothing is that tentative. Once they give up some, they set a precedent.
I kind of wonder if, in their scoring mechanism that decides what to show to who, they dock you a few points for product links though. I've been doing "what I've been reading" posts on FB lately, and people don't seem to notice them much.
You only get an aggregate view of what people bought and in what quantities. There is no way to know who bought what.
I know that feeling of the problems seeming impossibly hard all too well - it was the same at the Physics Olympiad, which was pushed pretty hard by one of the physics teachers at my high school (in Austria), who also happened to be one of the organisers of the state and national events. It helps to know that the problems are intended to be so hard that nobody gets full marks. I didn't realise this early on, but it's of course obvious in hindsight - you wouldn't want a draw, you want a nice, clean exponential distribution of scores. (unlike an exam, where a gaussian distribution is usually what you're after)

It sounds as if the IOI organisers (or at least the Danish organisers) provide possible solutions/approaches for the problems. This is great, it always pissed me off no end at the Physics Olympiad that everything was all hush hush and you had to try and find someone to explain the problems you failed miserably on as we never got to see the correct answers (let alone a breakdown of our scores by problem).

I think the national format varies from country to country, but in case it's of interest:

In our case, the Physics and, as far as I know, Maths & Chemistry Olympiads were split into school, state, and 2 stages of national competitions. I think each school sent up to 4 people (selection up to the school) to the state competition, which was standardised across the country and was half a day. The best 3(?) from each state, plus a selection of those with high scores then made it to the first round of the federal competition, which I think was a whole-day "exam". The best 15 or so from that then went for a 2-week intensive course held in different cities each year, with 4 different physics teachers teaching you new physics all day. It culminated in a 2-day competition, from which the top 5 got to go on yet another 1-week intensive course and the international competition.

(much to my surprise, I ended up qualifying for the IPhO 3 times, in 2000, 2001 and 2002 but only ended up participating once in 2001 [Antalya, Turkey] - for these events it helps to live in a country with a small population I guess)

I kind of wish I'd been sufficiently driven to self-study for the Informatics Olympiad at the time. (CS was nonexistant at my school; I'd only vaguely heard of the IOI, whereas Physics, Chemistry and Maths were encouraged - I probably tried the maths one too young, I was sufficiently intimidated not to try it again; the physics teacher was a lot more welcoming and better at keeping all ages making progress) I bet I'd be a better programmer for it now, and I had all the time in the world back then.

In any case: good luck Simon!

I participated on the National Olympiads in Informatics in Portugal, where I live. There was a first phase online, and then a second (final) phase in Porto. From the ~60 participants, only 30 qualified for the final. I got 10th.

At the final qualification though, I got 19th, and only the first 4 get to go to Italy this year, for the International Olympiads in Informatics. I can still participate next year, for a chance to go to Australia.

Even though it didn't go out that well this year, I learnt a lot, and it was a very amusing experience. Oh, and I learnt lots of stuff, like Dynamic Programming, Divide And Conquer, Kadan's Algorithm, DFS & BFS, etc. Highly recommend it!
2007 was hardly "a more innocent time" for the Internet.

Couldn't you implement a clumsy manual version of the 'expired' header you're proposing, by doing something like having your server precede each page with "The following has not been modified since …, and should not be regarded as current" if it is more than a certain amount of time old?
I think it comes down to how you define work. If it is "clocked in on a time card sitting at a desk" 130 hours a week is not realistic long term (it is 18.5 hours per day 7 days a week) -- I agree.

If you define work as "your mind focusing on solving problems or thinking about the big decisions that need to be made" it is absolutely possible to do that for an extended period of time.

I regularly sleep 4-6 hours per night and wake up without an alarm clock (there is a bunch of information about this out there now, example article: http://www.bbc.co.uk/news/magazine-16964783 ). When I'm awake my mind is constantly thinking about the projects I'm involved in and how I can contribute to the team driving a better outcome.

I don't put in 130 hours every week but I'm putting in over 80 -- not because I have to but because I enjoy it. I'm typically only at my desk or in meetings at a corporate office 30-40 hours a week. Part of the "freedom" it talks about is letting people work from where they're most productive in a manner they choose -- not forcing them into a "one size fits all" approach -- measure productivity by outcomes not by methods.

I have a "work productivity device" (laptop, tablet, or smartphone) open consuming information or producing output related to my role easily 80 hours a week (12-15 hours a day M-F and 5-20 hours on the weekends).

If I had to guess I'd say it's because the video is targeted at people for which this will be obvious. They aren't looking to sell this directly to consumers. They want to license the cooling technology. As far as they are concerned, the noise of the motor is probably as irrelevant as the bracket's color.
It's not a computer. It does not perform any logic operations. (unless you are referring to the actual central computer, in which case that will cost you much more than $50)

These things already exist. They're called station hubs, and you can buy them from Wyse/Dell, HP, and other retailers for less than $100.

I'd be very interested to see one be sold for $50 dollars, but I'll believe it when they're actually being sold at that price.
If you're having problems like this, your web development environment is total garbage and should be fixed.
