I downshift on hills because that keeps more of my stopping power ready to use. Brakes heat up when you use them continuously, reducing their effectiveness.
No, that’s just my standard “definitions are boring, let’s just agree to not discuss them”-disclaimer. Ah, well.

Definitions don’t make the problem hard. There is just no one true definition of beach, that’s fine. We can agree to use the one most commonly used or you can pick one, it doesn’t matter as long as we communicate the definition we are using.

I again and again find it astonishing that so many people have problems understanding what definitions are all about. They are about communication. Arguing about definitions is rather pointless, at least if you goal is to learn something about the world. (Good definitions make communication easier so there is room for argument about definitions but not really in this case.)
Against the real enemy: why organized labor should join with entrepreneurs
MongoDB is good, and Mongoid has a lot of features. However, I ran into a few Mongoid bugs that bothered me and I am transitioning my project to PostgreSQL.

Part of that is because my boss added a lot of features to the project that are easier to implement with normalized data. I could write JavaScript map/reduce functions to handle some of the cases, but using ActiveRecord 3.1 will be easier for me and easier for the next guy to maintain.

Everyone should try Mongoid out to learn its strengths. I agree with Ilya Grigorik when he says 90+% of the time SQL remains the most practical solution for the problem at hand (paraphrased).
An absolutely fantastic idea. It's a shame it will never happen.
Prototyping without database migrations is amazing.

Prototyping with normalization and fast joins is amazing as well, SQL's awesome!
Everyone realizes there are multiple forms of the Galaxy S, right? There's the i9000 international version which quite heavily resembles the iPhone, the Vibrant and the Fascinate/Mesmerize (SGH-T959, SCH-I500, respectively), which maintain a strong resemblance, but have the four soft keys, the Epic (SPH-D700), which departs even more in looks, and the Captivate (SGH-I897), which basically looks nothing like the iPhone, excluding consideration for all the TouchWiz junk. (I'm using US nomenclature here, if you can't tell.)

As of this writing, there exist quite a few comments in the threads derived from the parent which go something like, "What? They don't look the same to me.", and, "Surely you're drunk! They're so the same.", with absolutely no mention of the specific models being argued about. Dumb.
I agree, but I just thought it was always a strong strategic move for Android because all the people who wanted to play Donkey Kong or Zelda would at least have the option to do so, whereas for iOS you have to jailbreak your device.
I don't think there is a computer in the world that has a worse uptime than myself. Even old cheap Windows ME boxes did a fair enough job of being able to run without impairment for more than 20 hours or so.

Your Commute is Killing You? Move to New York
This is a special message to fellow California or Pacific Northwest engineers following a Slate article entitled “Your Commute is Killing You”, which compared my commute with assembling IKEA furniture and called it a “migraine-inducing life-suck”. I commute 45 minutes, each direction, every day. Unlike most people described in this article I have taken complete control of this issue and have made my commute productive, enjoyable and one of those things to look forward to, both directions.

Keep Reading, then drop me a note at dblock[at]dblock[dot]org with a link to your Github account and I’ll help you get a job at a NY start-up.
Great point, then maybe avree (above) is correct and the code was indeed stolen.
This looks nice, but I prefer the functionality provided in vim. In your .vimrc, you can set grepprg to ack, grep, or (my favorite super fast search) git grep. Then if you want to display the results just type ":copen".

Example: "set grepprg=git\ grep\ -n"
Unions on both sides of the Atlantic have made huge strategic errors in the last three decades that have eroded much of their influence, relevance and power.

Embracing enterprise and entrepreneurs in a deep way would a massive stride forward. I don't see it happening though. Finding a common enemy to unite against is one thing, but the fundamental shift in outlook required to go beyond that is something else altogether.

Labo(u)r will find other ways to organize in the 21st century instead forming/joining 20th century style unions.
For servers and VMs without much internal entropy, they could use a random number server. On boot, they could pull random seed data from a web service like random.org or by hashing Google News headlines.

Making Music and Dance Out of Stars
Im not an anything (maybe hacker) but my understand is that its centred on power and current materials. I understand it as follows:

Increasing clock speed means increasing power usage, smaller designs means that quantum tunnelling effects increases the probability of electron leakage - requiring even more power, conversely more power makes electrons more likely to leak making cpus less efficient and hotter. performing non reversible computation increases entropy as information is converted to heat, more heat means less efficient and less reliable. So using current materials, more smaller transistors operating at high clock speeds performing non reversible computations means a lot of power and heat. My take is that they are trading away clock speed and keeping smaller sizes and a slightly better more 3d architecture to keep gains up.

The dev blog entry was definitely one of the best I've read in a while on lessons learnt from a project. This line in particular,

The main idea was: “Stop worrying about if there’s something better. If you can do it right now then just go with that.”.

Says it all. That's a difficult wall to break past and I've struggled and I'm still struggling with it for my Android app. And I don't even have an app review to pass.... shame on me for not having any app out there. Thanks a lot for sharing this. The dev article was definitely an inspiration. Ah well. Good luck with the future run of this. You are right. This database does have a huge amount of potential in it so it'll be interesting to see where this goes :).

The author spends a lot of the article wondering about why Big Labor seems to be whiffing so many obvious opportunities (joining with entrepreneurs is the hook but it's really just one special case of the larger point), but the answer is obvious once you drop the theory for a moment and look at the reality: Big Labor leadership is not the same as Big Labor membership. Leadership has long since become its own entity, and succumbed to the first law of organizations: All organizations inevitably evolve until the perpetuation of their own existence becomes their overriding priority. Big Labor and Big Business are adversarial, certainly, I don't think claiming they are in cahoots adequately explains the behavior we see, but they do require the same basic environment to exist in. Which the article itself points out, but since he's collapsed the two distinct entities into one he isn't quite able to follow through on what it means.

It probably is in the interests of the membership to join with and support entrepreneurs. It is absolutely not in the interest of the leadership to do so.

(I know there is more than one union; I speak in the singular for convenience. In practice it seems to me pretty much every union you've ever heard of is all in the same place.)

The author also trots out the terrible "voting against their best interests" argument (insulting those who don't believe what you do is generally an unpersuasive argument technique) after three pages of explaining how supporting unions has failed to produce the best outcome, the irony apparently lost on the author. I don't vote Democrat precisely because I do not believe it to be in my best interests. I believe with what is IMHO some justification that they tend to trade short-term gains for long term losses, and tend to simply create new entrenched interests instead of protecting mine. I live in Michigan, where the long term losses have arrived. A lot of people have voted their "best interests" around here. Perhaps less insulting and more verification that it really is their "best interests" being served is in order. Second order effects can't be ignored.

The real point of the preceding paragraphs not being to prove that my beliefs are true, as justifying them here would be a waste of time, but that the assumption that not voting Democrat must be motivated by stupidity and lack of self-interest is not fully justified. There are good reasons not to vote Democrat. (There are good reasons not to vote any particular party.)

(Oh, and don't mentally translate "I don't vote Democrat" to "I vote Republican", BTW. It would not be accurate.)

I think you should reread my post regarding "charities". I said that it's easy for people to mistake Google and other companies for charities because they provide so many free to use services.

I never said open source is a magic bullet for anything. My original point was simply that you cannot equate relying on a third-party API to relying on an open source project. There's a risk to both, but they're very different risks.

Even perpetually licensed proprietary software that you download and run yourself has the advantage that you yourself decide when you want to stop using it.

For instance, even if ASP.NET might be discontinued at some point as was VB6, nobody from Microsoft is going to come knocking on your door telling you that you need to shut down your webserver.

However, if you built your platform around Azure and used tons of services and libraries only available there, you'd have a huge problem the day the Microsoft decided to discontinue Azure or quadrupled the price.

Some APIs are easy to replace, and some are not. I brought up the Skype API because it's one that is not easy to replace. I agree that ecosystems are different, so maybe that was a bad comparison. A better example is relying on Google App Engine or Amazon EC2/EBS, or some other API that has no viable alternatives. More complex and differentiated APIs have higher value, but also higher risk since you can't move away from them as easily.
I usually don't support the use of the words "tl;dr", but I think in this case it's justified. The answer is: ..... no.

I really wish GA tracked all the metrics exposed by the timing spec, instead of combining them into one overall value. It's great that this reports numbers from actual users' machines instead of a headless render process on a monitoring server somewhere though. Here is hoping FF implements support for this soon.
Well, the reason I built this is that it's much nicer to browse the results IMO. You can collapse files, you get bolded fonts, you get different colors, and much better use of whitespace. It's also easier to define options like regex and case-sensitivity vs. having to remember the flags in the command.

The benefit is one of UI/UX, it doesn't actually perform an action you couldn't perform text-only.

I find it very useful when dealing with unit conversions and fundamental constants. Google is fine for simple stuff but Alpha really excels when you have extremely complicated combinations of units. This probably doesn't matter much outside of physics but within it Wolfram Alpha is a godsend.

As I grew up in the same town as UIUC, I'm admittedly biased on this, but if you're just looking to get a top-rate CS education, there aren't many better options.

However, if you do end up putting in for transfers to other schools, you should make sure you're not misusing homonyms in your essays. You consistently used 'faired' in your post, where in the context you meant 'fared'. This would likely be a huge red flag to anyone reading your entrance essays, and is akin to saying something is a 'waist of time' or 'arrow-dynamic'.

Anyway, the point is that you're already enrolled in a top CS program. I know a number of people who tried to transfer schools, and it rarely worked out as they planned (similar to your dad's situation with Wharton) - as the new guy, it's often difficult to break into set circles of friends.
The proposed solution uses brute-force. How fast can you try another approach like backtracking if you're writing 30% more LOC?
While I like being able to pick out things quickly, I find that displaying comment scores tends to encourage a herd mentality. It's subjective, but ever since the comment scores have been disabled it seems like there are a lot more diverse viewpoints being expressed.

Also I might just be weird in this regard, but I find being "scored" on the things you say to be sort of creepy. I like feedback, and that's difficult to convey well on the internet, but turning ideas into popularity contests seems perverse to me.
I see the most promising line as actually being something considerably different from Wikipedia, rather than an opposition to it, which despite the top-line rhetoric does seem to be what the proposal is hinting at.

Wikipedia aims to be a summary of existing sources (books, journal articles, newspapers, etc.), with citation to where it got its material, but originating nothing; basically, the ultimate tertiary source. I think that's a useful thing to have, but it's not the only possible thing you could imagine building.

"True and useful" is a rather different set of criteria, and there is a whole space of websites that could pursue that, ranging from some that already exist (music and literary fansites, some academic wikis, knowyourmeme.com, Everything2) to many that don't yet.
Try these in Google:

flights visible from Modesto, CA
cepheids visible from Modesto, CA
distance from Mars to Jupiter

Now try them in WolframAlpha. See the difference?

Google is a search engine. It tries to find web pages that it thinks are relevant to those searches. It is very sophisticated at this, so as to try to figure out what pages actually have the information, and which just happen to have the words. However, since these are things that probably no one has written about on the web, you get nothing really useful.

WolframAlphas is NOT a search engine. It treats those same queries as requests to try to answer them from its databases or by computing them from things that are in its databases. So, for the first it figures out that you are interested in scheduled airplane flights that you can see from a particular location. It has airline flight data and radar tracking data, and from that, and it's model of visibility, it figures out what planes could possibly be seen from Modesto, taking into account their last known position and heading and extrapolating to account for the fact that the radar data it gets is behind by something like 15 minutes. (Click on a flight in the resulting list, and it gives you neat information about it, such as when it took off, how late that was, a plot of its course, graphs of altitude vs. time, groundspeed vs. time, and heading vs. time).

The second is similar. It figures out that Cepheids are a kind of star, gets a list of the 100 brightest Cepheids, and figures out which are above the horizon at Modesto, CA, right now.

For the third, it decides you are talking about planets (although you can tell it you mean Jupiter, FL and one of the several cities named Mars if you wish), and from their orbital information (which it has in its database) it calculates where they are now, and tells you the distance between them.
True, and that sounds like a place where the law is being tested in a way the original authors never anticipated.
Depends on which location you're hiring in. (if any)

Sure, or even have to share emergency resources. I mean, why on earth would an ambulance attend a person who's seriously injured because they exercised their right to be comfortable when the ambulance could be attending someone who actually took some responsibility for his own safety and considers the well-being of the community at large.

Not that I'm this much of a bastard, but for those of us that have faith-based issues around community-provided health services.
Quite ambitious. I like it.

This post is a few months old, though, and no public developments can be seen. I hope it goes on.
Thanks! Hope it helps. I'm still struggling to find the limits myself. Since I'm usually at the never-release end of the spectrum I found it healthy to try it the other way round for a change, even if the end result is not (yet) very pretty.
This is a small focus-group study that reports qualitative conclusions. It's not like they're trying to calculate statistical significance or something. It's aimed to be a better version of the "folk wisdom" that pops up on sites such as these.

Focus group studies have value. They're a kind of evidence that pushes weakly across a very broad front. Controlled studies are a scalpel: they produce high-confidence answers to very specific questions. Sometimes instead you need an axe. You don't know what specific question to ask, and sitting there doing controlled studies with no real clue about what's going on isn't going to be productive.

I'll put it this way: when you don't know much about a subject, there's an almost limitless number of hypotheses to consider. It doesn't make sense to prematurely promote one of those to the status of "working theory" and start doing properly controlled studies to test it. You have no real reason to believe it in the first place.
I hadn't seen Chrome2Phone, the choice is yours xD -- I guess I'll focus my efforts on iOS.

Interesting, a friend of mine used to own a chain of restaurants in Chicago, recently he went out to dinner at a nice restaurant with family, he said that his sister-in-law's boyfriend had some habits that indicated a similar to the personality that's described here, but that aren't as obviously obnoxious. For example if a waiter didn't introduce themselves by name he'd ask theirs, apparently waiters hate stuff like this because it's such an unequal relationship.
You seem to confuse hacking with cracking (I blame the media for misinformation, not you). Hacking is more about creative solutions to problems not breaking into (unlawfully) computer systems and websites. Wikipedia offers a good (but incomplete) description of what a hacker does (http://en.wikipedia.org/wiki/Hacker_%28hobbyist%29). Check this article by RMS (http://stallman.org/articles/on-hacking.html).

"but clock speed hasn't gone up since ~2004."

And yet the latest i7s run circles around the CPUs of that time period, even when running code that is strictly single-threaded.

There have been tons of performance wins made over the last 10 years that aren't just from adding more cores and Intel's predictions were more or less right on the money, if you overlook the marketing mistake common at that time of using ghz as a shorthand for overall chip performance.
