At the rates they do jumps, there appears to be about a 1-2% annual chance of a fatality. Would such an event end the business? If so, this would change the expected value and the true cost of a jump.
Visually appealing, but needs longer titles and link to HN comments. I usually find the comments more enjoyable to read than the source articles.
I don't think that anyone argues that mousing to small, arbitrary targets is more reliable or faster than keyboarding. Menus are a special case in this study because they abut the top of the screen (at least, if your OS's UX is reasonable), so you only have to care about x-axis accuracy.

Try mousing to the reply button on a HN page vs mousing to the Edit menu, it's easy to see why one might be faster even if your pointer is closer to the reply target.
People say it's safer than driving, etc. In 26 years I know 0 people that have been injured or killed driving.

In 3 years jumping I've seen some pretty gruesome stuff. Don't believe the stats, you're exposing your body to lots of kinetic energy and we're pretty fragile. No nightmares or PTSD, but, let's just say I've seen the helicopter land more than I'd like.

The injury rate for first time jumpers doing tandems is near zero. Its all people hurting themselves, similar to someone buying a fast car and getting in a car accident while pushing 120mph. It happens and you think "Well... At least we all warned him to take it easy a bunch before his accident."
Maybe we should stop kicking out the people from foreign countries with the advanced degrees they earn here.
While they were still choosing targets that either "deserved" it for some moderately reasonable ideological reason (Sony) or should have top-notch security (FBI), yes. Now that they're choosing targets at random, no.

Especially since this is all so likely to end in an acceleration of government crackdown on web freedoms.

The $500k theft isn't a vulnerability with Bitcoin. If you stick half a million in your mattress and your house burns down, who's to blame for that? The price on the exchange has always been volatile with a small amount of volume. So, basically, nothing has changed. If it's unsafe to put your eggs in the Bitcoin basket now, it was before too.
October 2010. Probably still relevant, and certainly interesting (to some), but not current "news".
This isn't interesting at all. every thread sleeps for that long. When you sleep, something like this happens:

The OS is told to wake up your thread after x time has elapsed. It puts this request into some data structure which it does something like poll from time to time so it knows what thread to wake up at what time. You are offloading your sort to the OS, which is probably then doing something like putting it into a linked list of timeouts that have been registered (maybe a heap?). After approximately the allotted time, some mechanism akin to a signal is used to tell your thread to wake up.

Also, usually the thread will just sleep AT LEAST as long as you tell it to sleep, but if the system is busy it could sleep a long time more. Threads can be woken up at the same time or slightly out of order, or 'woken up' only to find that all the cpu's are working on something else, and thus waiting for a time slice, getting one, then waiting again, and not getting to use stdout for weeks. It's uncommon to see machines with really high load these days, but a 1 core computer with 25000 processes all competing for CPU time, and which is swapping heavily, will potentially run each process millions of times slower than running one process.

TLDR; This is curious, but will fail much of the time, has huge memory overhead. Lots of good sorts are in place, this one requires something like 8mb per thread on linux due to the stack allocated for the thread. At best this takes millions of years potentially, and just does some other sort anyway.
Reading in the Cloud
The mouse, when chosen as the primary user interface (for something other than a fundamentally-spatial task, like CAD) is a soul-destroyer.

This is because operating a mouse-based user interface is a conscious process - one which cannot be fully relegated to "muscle memory." Unlike the keyboard, the mouse scarcely rewards learning at all.

Erik Naggum, in a Usenet post (circa 1997) explains this far better than I could:

"The clumsiness of people who have to engage their brain at every step is unbearably painful to watch, at least to me, and that's what the novice-friendly software makes people do, because there's no elegance in them, it's just a mass of features to be learned by rote... it's sadly obvious that we are moving into a way of working that is predominantly _conscious_, for which I believe the human brain was never prepared. we no longer have the time to let skills sink into the autonomous nervous system, as it were, and even if we try, the criminal in Redmond, WA, has a new, incompatible version out by the time we learned the last version... One of the joys of learning to ride a bicycle is to stop thinking about it -- the feeling that I had successfully programmed my body to master a bicycle at least thrilled me as a kid (except I didn't know the verb "to program")... we need to communicate to users that learning to use Emacs is like learning to ride a bicycle -- it does take some time and effort, it's a worth-while skill to have, and then you never forget. I firmly believe that the novice-friendly software is like giving people several sets of supporting wheels so they won't tilt, but could get moving right away, and then never taking them off, preferring that they keep using them and moving so slowly that they always need them. of course, if you argue that they should remove the supporting wheels to such users, they will, admittedly correctly, argue that they will fall _splat_ on the ground and ruin their three-piece suits. clearly a no-go."

Comacast was charging me 4 or 5 times more than Netflix per month and still, twenty minutes of every hour consisted of advertising. That is, a third of my watching time was spent muting the television and twiddling my thumbs.

Pretty much Comcast can go jump in a lake as far as I'm concerned. Of course, now that Comcast, through MSNBC, provides both service AND content, I'm sure they'll put a stop to Netflix as soon as possible. Thanks, FCC!

I can be a pessimist with the best of them, but this is just panic-mongering.

-- The US would be insane to default; their debts are mostly internal, and in their own currency, which they can just inflate. Unpleasant for Americans, whose pensions and savings are going to be worth a lot less, but this is how you pay for living beyond your means. If they need to change some technical rule, they will find a way of doing that, rather than default on debts and cause chaos.

-- Unlike Iceland, which physically lacked the money to pay its debts, Greece simply doesn't want to cut its government spending by 10% and pay its creditors. They are a sovereign nation, so nobody can force them to. Fine. After they default, and the financing gets cut off anyway, they will have to cut spending even more. Maybe after other nations will see how that works out for them, they will think twice about not paying debts that they voluntarily took on. Or maybe not. But let's not start hyperventilating about an Austrian default just yet.

-- China has had two decades of solid economic growth. Make that fantastic economic growth. I am not talking about numbers on paper, it's growth measured in concrete and steel and food. They'll live through a correction if they have to.
ESPN is the costliest "basic" channel that the cable companies provide. As of 2008, it was $3.65 per subscriber per month, and ever increasing as new broadcast contracts are signed with various leagues. It's very debatable whether a $10 / month ala carte alternative would do better for them.
I wonder if there's some kind of agreement that prohibits them from pulling the end-around on cable? Anyone know? Even if they could pull it off, they probably don't want to bite the hand that feeds.

The Rise Of The API, The Future Of The Web
I'd like to see a breakdown of exactly what's faster and what isn't. Obviously, typing text by clicking on an onscreen qwerty keyboard (or better yet, a menu) would not be faster than typing via a regular keyboard, so the mouse isn't always faster than the keyboard. Is typing text some magical special case where the mouse becomes much slower? I find that hard to believe.

Tog's article makes it sound like mousing is always faster, but that's clearly and incontrovertibly wrong. I know nuance doesn't make for an eye-catching headline, but it would be nice to see somewhere in the essay.
The banks don't seem all that secure lately, either. I think that puts things into perspective a little, compared to Bitcoin.

Considering that Bitcoin is a new digital currency and the software for it is not that mature yet, I don't think what happened recently should be that surprising.

It's beta software that is quite appealing to hackers because there are money involved, so attacks or flaws like these should've been expected. It's the risk the early adopters had to take, and some or most of them made a lot of money in the process by taking that risk.

The only mistake was in believing that Bitcoin was going to be 100% safe forever with no further improvements, and securing the clients and transactions as much as possible. But this is because it's still early for it, and it does have a lot of potential, so I wouldn't give up on it.

Bitcoin also needs a real economy behind it, not just speculation, so the faster that bitcoin economy grows, the better it is for bitcoin.

Interesting concept to return matching links via the Omnibox.
I've been ranting on this stuff for a couple years now to my friends. There are some alarming trends.. First off, a pen test is often treated the same as an attorney client relationship. If the test turns up particularly costly bad news, I've seen a handful of testers have the relationship essentially severed, received some hard language about talking about it from a lawyer and then received a check from a private account as if the company doesn't want to leave any traces that they actually knew about the problems. (I'm not joking, some medium sized companies have done this)

With some of the regulations the big missing piece is openness, there is no transparency into it at all. Any audited company should say who audited them and then after some period of time, 180 days maybe, the audit should be made public. The business risk is that customers will leave, in many cases like Playstation Network, customers effectively can't leave, they've already invested in something and there isn't an alternative. In many other cases it's not typically going to be widely publicized. If the customers can't leave, en mass, there is no business pressure for security and without any transparency the regulations will simply be gamed.
I get that it could, is there a reason you think it actually does?

Either way, nice observation. Interesting.

Scrolling and selecting with the mouse I can see, but do you actually copy and paste with the mouse too (i.e. through the context menu, or with the copy/paste buttons on the toolbar, if there is one)?

When I work with the mouse, I use my right hand (on the mouse) to select and my left hand (on the keyboard) to cut, copy and paste.

A more reasonable example than using Ctrl-P to Print is Ctrl-S to Save, I think. It's so much easier to hit Ctrl-S when you already have your left hand on the keyboard than using the mouse, and frankly I see no reason to ever remove my left hand from the keyboard.
Bitcoin is a massive opportunity still going through growing pains. I think there'll be second generation cryptocurrencies, but nothing to compete with bitcoin in this round.

Thanks for sharing your story! Great to hears different business owners experiences with Groupon.

One of our clients who operates a semi-private golf course ran a Groupon earlier this season and had great experience with it. It definitely generated a different type of a customer, or at least not the type of clientele they generally experience.

Basically, as a result Groupon allowed them to draw and market their golf course to a completely different target market. The only catch is, trying to convert the one time Groupon customer into a long term returning player or even try to up-sell them with Club Membership.

Groupon can be very costly, especially if your business model isn't a good fit for it. But just like any other marketing, running a proper business and cost analysis can determine if Groupon is the right fit. Otherwise you might become another example of Groupon disaster story.
I want to believe this, but I don' think there is a congruent market for legal goods that are willing to take BitCoins online. If buy an eighth from my dealer, he can go buy milk and bread. If I buy an eighth from someone on SilkRoad, they can... buy electronics on NewEgg (which would stop if USD exchange stopped)... and that's about it.

There aren't too many bike paths in Toronto, or Ontario as a whole. However the law dictates that cyclists have the right to use a full lane if they want to, which is quite great. If you don't feel to comfortable to have cars passing by you so close, then you can take up the whole lane, and they will be forced to overtake you as if you are a car.

This decision is astutely analyzed by Eric Goldman here: http://blog.ericgoldman.org/archives/2011/06/righthaven_benc....

This is a devastating loss for Righthaven.

Among other things:

1. The core defect exposed by this ruling - Righthaven's lack of standing to bring any claims for copyright infringement - applies to all 200 RH cases pending in Nevada and likely those in Colorado as well.

2. The defect can't be fixed as to the existing cases, putting all pending RH cases in jeopardy.

3. The judge found serious procedural misconduct by RH and gave it two weeks to "show cause," in writing, why it should not be sanctioned. Court rules say you have to disclose the name of anyone who has a financial stake in the litigation. RH failed to do so concerning Stephens Media, which holds a 50% right to any recovery. It failed to do so in any of the 200 cases filed in Nevada, leaving the judge seriously disturbed by this and by other RH misrepresentations made to the court. Thus, not only will RH likely get bounced in all its cases, it will probably have to pay a pretty penny for having abused the court's processes in putting on its charade. No more devastating outcome could be imagined for a litigation campaign of this type.

4. Perhaps the most interesting tidbit that came out: in an editorial, Sherman Frederick, formerly of the Las Vegas Review-Journal, had threatened to introduce his "little friend called Righthaven" to those who published his paper's content, an unmistakable reference to Al Pacino's "little friend" in the movie Scarface, an M-16 machine gun with grenade launcher - capturing in brief the hubris behind the whole RH campaign and perhaps more than anything else explaining why this judge has decided to make RH pay for that hubris.

An appeal is inevitable but, for now, RH is watching its business model crumble.

You make a valid point, but I think it's missing the forest. The example I posted actually results in a Fixnum. It's addition, not multiplication.

Simple math operations are an admittedly terrible way to demonstrate the point I was trying to make (method dispatch and object instantiation overhead). Dismiss it, accept it, or dig deeper verify it. :-)
(Warning: I am very opinionated on this matter)

I made a switch from PC to Apple 4 years ago. The lack of meaningful keyboard shortcuts drives me mad. Consider a simple task of switching applications with the Cmd-Tab key: Minimize the only window of your application. Switch to another program, then cmd-tab back to your original program. Where did the window go? Oh, it's still sitting in the dock. So, grab the mouse, go get your window - and if you have 3 monitors (like I do), your mouse can be in a different zip code and it takes a long time just to find the cursor.

In fact, I think if we did this study today, we would find that due to bigger screen sizes, it's harder to spot the cursor, which would probably increase "mousing" time. However, Apple has 6 modifier keys on a laptop: Shift, Fn, Control, alt, option, and cmd, so trying to remember these keys can be a challenge too (and drives me crazy as well). What is the full screenshot shortcut? Control-Cmd-Shift-3 (aka finger-gymnastics)

"Sorry, I don't see the contradiction at all. Of course journalism is about asking "tough questions" but there's nothing that compels the interviewee to answer those questions, and even if they do answer truthfully their "truth" may differ from yours."

Sorry, I guess I wasn't being very clear earlier.

What I meant was, by the same argument as to why the author couldn't talk to store owners, by that very same logic, journalists can never talk to primary sources. Because I can take any journalistic piece, and say "the source that the jouranlist talked to is just making up answers because XYZ".

And like I tried to explain, the way out of this mess is a few things - the journalist can interrogate and try to get past the bias of the source, and they can also promise to keep conversations off the record.

But saying "well I can't talk to primary sources, I'll just talk to other people" is a cop-out. Especially when the other people also have a clear bias in this story.

- US: Semantics. US is already silently defaulting by massive printing its currency (thus devaluation of its debt). Regular citizens' social security, medicare, and savings are wiped out. Still points to economic depression.

- Europe: They all will default. If one country in EU doesn't pay its debt back, why should the other countries in EU pay theirs? Major banks in EU suffers massive loss of value. Still points to economic depression.

- China: Yes, they will go through a correction. However, since they packed 40 years of economic growth into 10 years, the correction will be brutal (oversupply in housing, capacity, human resources). Still points to economic depression.
