My favorite one is Russel's Paradox[1], which actually became the proof that there is no such thing as the Set of all Sets (under traditional set theory[2]).

Which was one of my first steps into Category Theory, as Set is a proper category[3].

Except that so many beliefs are not rational.

I think that this would be a valid example: you believe that you're mad at someone (belief), but you nevertheless act professionally with them (alief). Except I suppose you may have a belief that you should act professionally despite being angry, so... pff. I know I don't have a good enough grasp when I can't come up with any decent examples.
Pretty clear based on what evidence? Why are you suggesting it is pilot's fault? Has the NTSB already issued a report?

How much more effective? The study done by Italcementi in 2002-2003 (admittedly not very trustworthy since it's done by the company that makes the product) has numbers comparable to the Eindhoven study.

Absolutely! At the game studio I work at our artist/animator uses Flash almost exclusively. He'll export each frame as an image and we'll feed them into our custom pipeline to get his animations in the game. From talking to him, it's the best animation tool available on the market. He made it clear that he'd never try to make a website or similar with it though.
I wonder if this falls under the category of uncanny valley.
I've acquired about five self-published books at a very low cost (including free) and they've all been shit. I have a hard time buying something these days that I don't think had an editor work through it, but I am concerned that editors will play a smaller and smaller role in the book business going forward.

I would like to see government run something like grand juries. Randomly conscript a commission of intelligent, well-educated people to study some issue, and let them make policy. A non-democratic government need not be totalitarian.
Fascinating about the phone. iOS only supports colemak on an external keyboard (or in a custom app) so I've not tried it there. You make perfect sense.

I made a move fairly similar to yours. I went for the Truly Ergonomic keyboard because laterally staggered keys seem stupid if you're giving up Sholes anyway.

I typed about 5-10 wpm for the first month. No matter what I tried, it was far too slow. Part of this was losing faith and moving keycaps (on mac keyboards) and putting letters on the TE. That gave me a crutch for a while that kept me slow, although I was careful to maintain hand position.

Then suddenly, it clicked, and I went from 15wpm to 50, then up to about 90. I'm still slower than I was with Sholes after 1.5-2 years now, but I can type on any keyboard and not have pain or tingling.

That said, I am back to about 5 wpm with Sholes, and I'm perfectly fine with it. Just as when I first switched to colemak, it makes my emails and documents much more brief. I think about dictating The Diving Bell and the Butterfly and choose my words carefully.

(This was obviously typed on colemak. :-))

It took a long time to get used to emacs keybindings. I ended up using arrow keys for a long time. P and F are close enough that I ended up with a lot of confused misses.

What I like about colemak over Dvorak is that Dvorak is a pain for a lot of common unix commands. 'ls' is especially onerous.
"IM conversations aren't like mailed letters- when they're received, they disappear forever. So it's vitally important that we gather all the information that we can before it disappears, so that we can later use it in intelligence efforts"

I'd place my skill bars higher: "thinking like a computer" seems fundamental: I don't think one can even be a mediocre programmer without it, and it's not enough to make you a good programmer.

A good programmer also needs to be able to effectively communicate through code to both others and themselves, know how to design maintainable programs, how to preemptively avoid bugs by making their code harder to misuse, and too many other skills to list here -- and not all of those naturally flow from knowing how to think like a computer.
I'm sure it does in some aspect.

A little too friendly and attempting to be helpful in terms of being "human-like", but approaching "not really" in terms of having no emotional feedback and constant repetition (we dislike predictability when negatives are affirmed) is rather upsetting.

I wasn't planning to either. But buying any medicine requires a prescription in the US, which may be fine depending on how you look at it.

What I was trying to say was that I found treatment 10x more expensive in the US; while other expenses are merely higher and generally affordable.
I'm going to take that article with a pinch of salt until Greenwald shows the evidence. It's entirely possible that a phone tapping technology + the vast new NSA data centre = "the ability to tap a billion calls a day". How many do they actually tap is the operative question here.

The original leaks were compromised by a lack of technical understanding stemming from the presentation slides we all saw, so I'll wait and see what he is basing this claim on first.

I switched to Dvorak 11+ years when I was in college and had a lot of time to kill. I think your spoken language fluency analogy is pretty accurate; I imagine I'll always retain a bit of my 'native' qwerty muscle-memory, but the more I practice it, the easier it is to make the mental 'switch' between languages.

That said, if I had to do it all over again, I wouldn't switch to Dvorak. The efficiency gained on my keyboard layout does not offset the efficiency lost on shared computers.

> It now allows you to switch between windows of the same application on the same desktop which has to be in the running for the most useless UI function ever devised.

Simply asking... WHY on earth would you find this useless?!

Agree, you wouldn't need it if you just had the ability to select a "don't combine taskbar buttons" option (last time I checked Unity didn't have this) - the first option that I select on Windows 7/8. To me different windows of the same application are technically "different apps/task" and I want them to show separately on the taskbar or at least have an easy way of switching between them. The whole "task based interface" current is the biggest UI/X fail in recent history imho, and a misnomer on top of it - applications aren't task, if I have two different web apps in two different windows (or simply two different sets of task specific tabs), they are two completely different tasks to me, I don't want them grouped by application goddamit!

Even philosophically, in the "UNIX way" tasks emerge when one combines the use of a number of small applications to get a particular task done, while in the "Mac/Windows way" of "big feature-full applications" an application can be used to work on multiple task simultaneously in different windows. 1 to 1 mapping of apps to tasks and the "combine windows on taskbar" philosophy only apply to very naive and inexperienced users that don't understand even 10% of the potential of the "tool" sitting in front of them, and they should not be catered for, they should be pushed and stressed to learn more whether they like it or not, because they can learn more, and they will inevitably get better at whatever they do by learning more - even Microsoft gets this (they know that if you are forced to learn more about their products and by learning more about them you become more productive with them, you will grow more dependent on them, whereas if something is "very easy" but limited, you'll be able to switch to a competing product that could give you even a minor increase in productivity at any time), even if would be suicide for them to admit it and put it in any marketing material since they market themselves as "easiest to use" :)

...overall, I feel like Unity simply cherry picked the worst features from Windows 7 and Mac OS GUIs. At least the Windows GUI can be very easily customized in all relevant aspects and allows me to be very productive with it, while the Mac OS one is well polished and tested and after I get used to it has a nice "flow". If you want to build an "opinionated" GUI, first make sure you are at least as competent as Apple's UI guys are, if not, just drop it make something clean and easily customizable with a Right Click -> Properties on any element so I don't have to hunt down a controll panel that, for Unity, doesn't even have the options I care about!

...thank god for KDE and XFCE!

A large portion of this cost is because some people don't pay, and they can run huge tabs. Meidicine is a business, and that cost has to be shifted to other patients to compensate.

In socialised systems, like Canada, physicians actually make more money because the government always pays so it's not a greed issue. The downside is that the government has limited funds, so the amount of beds, ORs, and advanced equipment is severely limited and wait lists are rediculous, ER times between 6-8 hours, chemotherapy wait lists of 8 months, surgeries 1 year + for the worst of surgeons. Alberta is the exception as they have rediculously deep pockets from oil revenue.

It's a trade off, this is a case of you get what you pay for. Free healthcare only works when the state has money to blow on quality care, I.e Texas with the Scottish Rite hospital.

You can't directly compare life expectancies with the US and places like France (which have free or near free healthcare) and conclude that it is just as good, if not better than America's. There are many confounding variables here (I.e their very short work weeks).
How much does the Affordable Care Act addresses this? I know insurance can't be denied to people with pre-existing conditions and there can't be any life-time expense caps. But is there any measure to address the high cost of health care in US?
Yeah but the author doesn't provide any summary stats or analysis like he/she does vs. qwerty. I would potentially be switching from dvorak - on average is there much difference?

I ended up pasting some posts from this thread into the compare tool. Colemak and dvorak seem pretty similar, with colemak consistently having slightly less same-finger usage (i.e. two keys in a row being pressed by the same finger). Both are about the same improvement over qwerty. Doesn't look like it's worth switching from dvorak.
Whoops.

Seriously, just copy the EU on healthcare. You might need to pay extra taxes, and take an extra insurance against hospitals fees. But it's all very affordable.

Doctors and medical facilities would need to make a lot less money. That is the source of most of the cost difference. The vehicle of payment is maybe a secondary cause. It might be good to change it, but if it's not directly responsible for the majority of the difference in what doctors are getting paid, it's not going to fix the problem.
Insurance providers don't pay these sky high rates so it effectively reduces the out of pocket expenses of patients, significantly.
The hospitals just charge that because they can. What most people don't know is that you can often negotiate them down.

Todays facebook crowd didn't grow up engrossed in consumer computers and the Internet from infancy, but from their preteens. I imagine the millenials will, having grown up entirely exposed to pervasive international information sharing, be more inquisitive as to how the devices that dictate their social lives work.

I mean, it is just my impression, but my 10 year old half brother can sit down at a Linux box and install games he wants to play in wine without having any idea what he is doing. That is more praise of wine than my brother, though =P

My argument is that when you grow engrossed in this technology it is much more influential on your life and thus most inquisitive minds would find it much more relevant to learn what they actually are, versus the older generations who only recently adopted these technologies as an accentuation of old habits. For one it is a tool, the other it is a way of life.

White smoke that is slow or lazy is most likely indicative
of early-stage heating. One more important note about smoke
color: brown smoke. Unfinished wood gives off a distinctive
brown smoke as it approaches late-stage heating (just prior
to flaming). In many cases, the only unfinished wood in a
structure are the wall studs, floor joists, and roof
rafters/trusses (photo 3). This can tell you that the fire
is transitioning from a contents fire to a structural fire.
Using our knowledge of building construction-especially
lightweight structural components and gusset plates-brown
smoke issuing from gable-end vents, eaves, and floor seams
becomes a warning sign of impending collapse.
In our country all laws have to be published in the "Staatsblad" (State-released paper/documents containing new businesses, laws, ...) So unless a law to allow secret laws was made we shouldn't have secret laws.

So that got me thinking, try outlawing secret laws ?
Why don't you elaborate instead of just yelling "free market!" and waving your hands? How might we encourage competition effectively?
Yes - it pays to have a big defib (not one of the 'press button now' mall variety), an experienced and qualified staff member or 5 with high level CPR training, and some good cardiac event type drugs, and a load of proper monitoring gear (heart rate, BP, etc). While these things aren't especially cheap, they would pay off fairly quickly at a decent clinic, and I was involved in the purchase of most this stuff for sub $10k US recently for a clinic (but got a mall style defib as our needs are different). Staff would be the greatest cost. That said, at 2k per test, most expenses for the year would be paid of in the first week or 3 at a busy clinic surely?

I broke my knee this spring but didn't go to a hospital on my families request because the last time I broke a bone I reset it myself and the hospital still charged $8k.

I still have blood in the joint, but I can't get it drained because no doctor will stick a needle in without an x-ray, but those are expensive. So I'm waiting till I move out and get a full time position in a bigger city to get health care to have it fixed.

It isn't a "duh" problem in the US. Especially in the presence of less educated or rural communities, who buy media propaganda that socialized medicine kills grannies, and amongst retirees who are already getting thousand dollar checks each month from the government but don't want anyone else getting any benefits, because the uninsured are "jobless hippies".

That, and there is a huge insurance lobby ripe with exploiting the corruption of congress and the 2 party oligopoly that keep pressure on maintaining insurer profits.

We pay significantly more by having every uninsured person come in with emergency needs rather than seeking preventative care, but the average American doesn't care, because they "deserve it" for not having a job that gives insurance. The ideology is completely backwards, but intentional on the parts of those who profit off it.
I have been using regular Dvorak. I took 3 months to reach my Qwerty speed, probably because I kept using Qwerty on the side. After a year my speed is 60 wpm, double that of what I had with Qwerty. The main difference I feel is not the speed, but a marked reduction in fatigue is your fingers. But I am back to hunt-and-peck typing in qwerty.
I definitely wouldn't suggest anyone switch for performance reasons. I switched because of pain. It helped that a lot. Made virtually no long-term difference in typing speed.

(Then again, my typing speed has been 90+ wpm since I was about 9, so I'm an outlier in various ways.)
you should check out http://0xdata.com/ ; it's built from the ground up on a custom dkv to do in-memory ML. Reasons to check it out:

1 - it's open source https://github.com/0xdata/h2o

2 - ingest data from hdfs, s3, csv

3 - I've built systems like what you're discussing twice; the ML algorithms are often easier to write than expected while data management (moving data, sending updates, etc) which initially seems easier is much harder. 0xdata handles this for you.

4 - under active development

5 - it cleanly runs on your dev box with 1 or many nodes for development; deploying is a simple as uploading a jar to a cluster and putting a single file on each naming peers in the cluster

5a - see scripts to walk you through doing this

disclosure: I work on it as of very recently =P
