The worst sodium has a half life of 15 hours.

The longest chlorine has a half life of 360,000 years, but is barely radioactive. The rest are all under an hour.

There's other stuff in sea water though. But not in large quantities.
I was trying to give a response along the lines of "that's like saying <x> is the most widely used <y>", but couldn't actually think of anything that made my point.

My point was going to be that pretty much no-one really uses ontologies.
Great explanation, Aaron, I agree 100%.

It's great to hear how much the product was/is loved!

Note that Wave's editor and OT really blew us away -- all of our "unique technology" was matched or exceeded in sophistication by Wave's! You could argue that given Wave's subsequent failure, we overestimated the importance of tech, but I'm inclined to think the tech is indeed a sticking point, given that no one else has matched it to this day.

An EtherPad successor would require a combination of the "simple" UX everyone loves with good tech and a business model. Somebody do it! I'm happy to share how EtherPad works.

Sorry, didn't see this reply.

We've been using EC2 for a while now, before most of these plugins were available for Heroku. We're extremely comfortable with the platform and our tools for managing it.

We have most of our customer-facing nodes on m1.large instances since we have a lot of caching (mostly loading all of the data in memory) up front and then the rest is CPU bound.

Scaling Heroku is nice since it's just some knobs you turn, but Chef isn't that much more difficult and it's just a different type of knob.
I've been saying for a while that I think the "next thing" is high-powered cellphones acting as a computing device (providing storage, connectivity, and processing power), with several different types of devices acting as dumb terminals.

If you're at home or at work, your keyboard and monitor auto-connect to your cellphone to provide a full-sized screen. If you're on the go, you use your cellphone as-is, or you use an eyepiece or tablet as an alternate display. Ideally, the main apps you use would provide appropriate user interfaces for each situation.
They are just flooding it and letting the water boil off.

Messaging App Roundup: The Finals
But tritium pretty much can't be made in light water reactors, so there isn't going to be any in the released steam.
I have a Facebook account but I barely check it, I just can't get addicted to it. I find the experience annoying, the site is a total mess, looking for your friends list takes major efforts for example. Why does it ask me to login to a bunch of site to import friends instead of showing me my list of friends?

The messaging system is terrible. Why can't they work at turning that into a more gmail type of experience. My feed is filled with crap I don't care about, I can't create groups of friends like "programmers" to whom I can share cool programming related links...

The list goes on but the site just doesn't work for me. After a couple minute I'm so annoyed I don't want to log back in. I'm not the only one, everyone I speak to seems to have the same issues as me but they still find use in the site and revisit it daily.
This is not really new, I was playing with it more than a year ago.
Because people with lisps should default to not being confident or capable?
The richter scale is pretty meaningless in that regard because it measures the total energy released by a quake, not the destructive power at a given point. To use it for a design spec, you'd have to specify the depth of the quake, the length and frequency of the shockwaves and, most importantly, the distance from the epicenter.

I'd be very interested to learn what those specs actually said. If it really was a Richter scale value, it would logically have to be at point blank, which this quake wasn't. If so, the energy that hit the reactors may well have been considerably less than what they were designed for,
How to Enchant Users by Guy Kawasaki at Stanford
My question: Why didn't the guy with the height issue not use his real name, or at least a contactable pseudonym?

I mean, with the latter he's not giving much away, and he might at least be able to attract attention from people who were looking for someone nice to be with who isn't shallow and self absorbed.

Also, if you're in this sort of a situation, I find that taking part in organizations where beauty isn't a primary value (religious and charitable institutions, political and social causes, for example) would let you get to know people better than just going in the deep end of the shallow, sex focused "dating scene" .

Google Docs will show you a diff, but without your comments. They also don't have a live preview of what your changes will look like. It also takes a lot more clicks (and time) to generate the revision history.

The overall point being that Google Docs does a lot more than I need. YMMV.

Ah, good hackers will eventually learn English, at their own pace though. Why spend 6 months in a really intensive English training course stopping everything else when you can have an influx of material on your own language now?

Plus, believe me when I say, not every Mexican teenager guy/gal with skills have the resources to pay a training course like the one you suggest (I didn't, learnt it on my own, took many years, still not perfect though).
The author must not be very experienced with iOS development because you can simply ignore all those extra empty methods if you do not wish to implement them.

argh it's even worse than that. the app is too big for gmail so i'm stuck. yea of course the app shouldn't be so big but this is testing and i built in some assets in this first draft.
Even now, there is no need to fear contamination of the environment. The amounts of radioactive material released are not significant, and even if a complete meltdown happens (which is not very likely at all even now), it cannot breach the safety containment.

"Passion, drive, perseverance, experience, patience, brilliance, etc."

You beat me to this list of qualities. The only minor disagreement is that brilliance shows up only after a good developer, who embodies your list of qualities, follows his/her interests and gets really familiar with a couple areas of the field. As an example, someone who enjoys hacking graphics at a low level will eventually become great at that area, but may be only good at language design.

Our field is too broad to be great at everything.

> I think it's brilliant that the boys at Facebook are taking on Netflix by developing their own streaming service

Assuming Dvorak's talking about the newly-announced Dark Nights rentals, he's talking about a third-party app developed by Warner Bros, not a ploy by Facebook itself.

I wouldn't bother bringing up a small factual error like this, but it really digs into the point of his article: it's a lot harder to build up the idea of Facebook as an evil monopolizing force trying to lock people into their platform when it's third-party content producers that are actively pulling people into the FB ecosystem.

You could argue that this is a result of their efforts to attract developers to the FB Credit platform, and that's just an attempt to attract and lock in users. That's definitely true, but you can't really call a neighborhood a 'ghetto' when it's got a posh shopping mall full of big-name department stores.
For a comparison of how bad it could have been, you just have to look 6 years back at Indonesia. The quake had pretty exactly the same strength, so I'd assume the tsunami was roughly as powerful.

The result: more than 10 times the death toll in an (I think) much less densely populated area. The effort and money Japan is able and willing to spend on earthquake/tsunami preparation has most certainly had a big effect. Even if devastation in the worst-hit areas is complete, a lot of people probably escaped because of the infrastructure and drills.
I bought an 11" Air because I wanted a laptop that was as close to an iPad as possible. I also have a 1st gen iPad - typing is an issue; coding's impossible but emails are OK (stick it in landscape and use the 1st gen Apple case and it's reasonable).

The Air is great but the real problem is when you are moving around. The iPad is perfectly natural to carry with you and to be used standing up - the Air, because of its laptop form factor just isn't.
Can somebody explain to me what SXSW is? I was always under the impression that it was a music festival in Austin, but it sounds like over the last 3 years it's morphed into some sort of "social media" expo/convention.

Has the entire world gone completely insane? A huge, publicly traded, multi-national consumer electronics company opens a place for people to spend money, and this is the most memorable part of SXSW?

"Well, sonny-boy, let me tell you about the best SXSW ever! Apple opened one of their stores right in the festival and let me give them my money! It was great!"

As an institution, law enforcement seldom worries about whether its actions might look thuggish to others. And antipiracy organizations are explicitly about pounding down David at the behest of Goliath (regardless of your political opinions, the pirates are unquestionably poorer and have less political might than most copyright litigators), so I doubt they'd be more concerned than the average.

I'm getting hammered pretty hard (Jimmy Wales decided to retweet it), and discovered a bug in my Apache configs, but have fixed it. It should hopefully hold up.

The larger bug is, of course, using Apache when if this had been on Nginx I would be snug in my bed right now instead of getting paged. shakes fist
Whole buildings moving at ~4:30 in.
why the iPad is truly exciting: we can see that it has great potential, and while we don’t quite know its nature yet, we’re pretty sure that it’s huge.

We can begin to see what this potential is already. The key is the form factor and the input. (I mean, what else is there to the iPad? The whole point of the design is to reduce it to that point.)

The form factor is about personal consumption of information and about interpersonal sharing of information. It's about handling data and content in a way which is immediate, as if the app were your content and your're handling your content directly -- not that there's an app between you and your content.

Focus on these two aspects, and there's a good chance that your app will be revolutionary and disruptive.
I find the experience annoying, the site is a total mess, looking for your friends list takes major efforts for example.

Yeah. It's ridiculous that there isn't an obvious link for your friends list when you log in. My daughter enlightened me to the unintuitive sequence of clicking Profile and then Friends.
It took me a split second to realize why you weren't citing the source.

So this phrase was just adapted into the book? I'm starting to fear you.
Ask HN: Workload in Uni more than in a CS Job?
According to my professor and some other people, they said that it's very possible that, as a Computer Science student, getting through university may be the largest workload that I have to handle.

So my question is, putting aside being a founder of a company, how would working in a cushy Computer Science job compare in terms of workload to university life? What particular CS-related jobs would require more/less work? More or less stress? Different flow of high volume workloads (eg. constant workload, high workload at particular times)?

If demographics is a factor, I'm a Computer Science student at the University of Toronto.
"Discoveries" are unlike ideas in that they build on each other, giving them value of their own.
I read what you wrote in the linked post, and your view of the situation appears to be... erm... too bright if you will.

Were there not repeated cooling system failure resulting cooling pumps running on batteries (that needed to be swapped every few hours)? This sounds to me less like "something working as designed" and more like scraping last fallback options. Releasing (lightly radioactive) steam to ease the pressure in a chamber they have no view or control over doesn't sound that much better either. Nor does the evacuation of 140,000 people "from the area around Fukushima".

All in all, based on the quotes of Japanese authorities that sip into the Reuters' feed - they did not have a situation under full control at several points. They handled it as professional as it's possible, no doubts about it, but it could've unfolded differently.
To be honest, it's a little bit embarassing to see such a... well, how would you call it? Flamewar, maybe.

I've been active in a irrelevant project of GNOME (ie. marketing), and my initial opininon still seems to hold: It's not about the desktop; it's about the apps. Neither GNOME's Shell nor Canonical's Unity solves any interesting problems for users.

And the lack of apps is basically just a matter of a missing business models for Open Source Desktop Applications.

To see them fighting over stuff that probably makes up -- at most -- 0.01 percent of the users' time, let's me wonder whether Open Source is ever going to be any major force on the desktop. I've once believed it would, but this belief dwindles.
Arrrg! Why is nobody understanding me? My intention was never to even hint at any deficiencies in Japanese preparedness. But, well, shit did hit the fan! I don’t know what else I should call the death of several thousand people. Those deaths were probably unavoidable and certainly no humans are to blame for them.

Between 100,000 and 300,000 people (the numbers are still very much unclear) were killed during the or in the aftermath of the much weaker earthquake in Haiti and if you look at other earthquakes you see similarly high death tolls – that tells me very clearly that Japan was extremely well prepared and I never for one second doubted that.
It started as a music festival in the late 80s, though "music festival" doesn't really cover what it was even then.

It was from the start more of a showcase for indie bands to make their mark than a festival in the same sense as most other fests. Bands with little exposure (but hopefully much talent) would be invited by the curators, and reps from all the record labels would show up. It was a chance to make a name for yourself. There's also a music biz conference that goes along with it.

They eventually added a film festival, and it's become a launching pad for indie filmmakers in the same way the music side did. It's not Sundance, but in some circles it's even more influential as it doesn't back off from genre material. It also has a biz conference for film.

In the last 10 years or so, they started playing up the "interactive" side as well. Basically a conference for new media, internet startups, etc. That's been gaining ground and is now an influential event in that arena as well.

It seems like it's on the verge of being a little too big these days, with not entirely favorable comparisons to ComicCon becoming more popular. It might outgrow its usefulness in the next couple of years, but right now it seems to be on top of the world in several arenas.
In case you missed it, the confusion resulted from an old Google page that explains how social search works.

The submitter's title is completely misleading.

Unfortunately, they aren't doing anything interesting.

With all respect, hackpad has a fraction of the features of the other etherpad forks (including the original etherpad). That's not necessarily a bad thing, but nor does it give me a reason to use it over say piratepad.
Kneejerk criticism first.

First question I asked myself: What does programming the Smalltalk-style message sending interface look like? What does [dict setObject:x forKey:y]; look like?

It looks like this:

dict:setObject_forKey(x, y);

Well.. okay. I know some people dislike the message sending syntax, but the API is written for that syntax. This is verbose, but readable (if you're familiar with Cocoa):

- (NSIndexPath )tableView:(UITableView )tableView targetIndexPathForMoveFromRowAtIndexPath:(NSIndexPath )sourceIndexPath toProposedIndexPath:(NSIndexPath )proposedIndexPath;

This, on other hand...

function tableView_targetIndexPathForMoveFromRowAtIndexPath_toProposedIndexPath(tableView, sourceIndexPath, proposedIndexPath);

...is... not winning the fight, let's say.

Second: what on earth is this:

function crunchCookie(self, sender)
self.button = self:view():viewWithTag(1)
self.button:setImage_forState(UIImage:imageNamed('cookie-crunched.png'), UIControlStateNormal)
self.label = self:view():viewWithTag(2)
self.label:setHidden(false)
end

Is this Android programming now? Do I have to fish my widgets out by hand?

Anyway, this still looks pretty cool. Hooking up a garbage collected scripting language on top of Obj-C with minimal memory overhead is awesome.
Tell HN: Friend's don't let friends apply to NYC Seed
Apologies to use a throwaway account and apologies again to bash somebody anonymously. I wish I could be more brave about this and say how I feel openly but the tech community is ny (or anywhere else for that matter) is small and I do not want to get in trouble by upsetting the wrong people.

2 months ago I ran into Owen Davis of NYC Seed. And I had an absolutely horrible experience dealing with him. He is arrogant, unfriendly, rude, unhelpful etc. There are a lot of people like him in the world and in tech communities which is fine I guess. You just learn to steer clear.

The problem is that Owen is very well-connected in the community and just recently I saw him pitching to get people to be a part of NYC Seed's summer incubator class. Please consider NOT applying/getting entangled with Owen who can be positively dangerous to young start-ups/people w/o experience because they are likely to take him seriously. If you know of others who are considering applying please warn them and ask them to ask around in the NY tech community for a second opinion.

Nobody will say anything openly given that he is so well-connected but you will be able to see what I mean when they hemm and haw. Check out thefunded to see what others say about him and the seed fund in the city.

I bit my tongue for 2 months because it really is no skin of my back but when I saw him inviting start-ups to apply I felt that I had to take a stand, even anonymously. It is like knowing a priest is abusive and too connected to expose so you do the best you can by trying not to send your boy to practice for the choir.
I suspect lawyers in all non-english-speaking countries may disagree with you. Equating poor english grammar with low intelligence is making rather a lot of conclusions from little data.
People had the same choice a decade ago, and chose against AOL.

I think Dvorak is simply pointing out the fact that Facebook is being praised like the second coming of Jesus, while AOL is regarded as an internet backwater and failure, where they both provide/provided very similar functions.
I am not sure I follow. Do you know of anyone in an open relationship who is in love and happy about their spouse fooling around with other people?

I know of none and I know quite a few people who did it, saw a couple of documentaries about it.

I am more than happy to be proven wrong but as far as I am concerned my point still stands and is fairly rational.

If you are in love, open relationships ain't what it's all pumped up to be.
Let me Google that for you...

Correct me if I got it wrong, but does it mean that putting any Python function in any() makes it run in C???

From my understanding, the any() version is faster is primarily because it avoids looking up .update() method each iteration. The usual Python way of optimizing such cases is:

# the original slow version
# 2.87753200531 sec
def run():
_md5 = hashlib.md5()
for i in itertools.repeat("foo", 10000000):
_md5.update(i)

# slight change
# 1.82029104233 sec
def run():
_md5 = hashlib.md5()
update = _md5.update

for i in itertools.repeat("foo", 10000000):
update(i)

# using any()
# 1.50683498383 sec
def run():
_md5 = hashlib.md5()
any(itertools.imap(_md5.update, itertools.repeat("foo", 10000000)))

Would love to hear feedback on the "practical" part of my rant. Unfortunately most of the comments on the post focused on the merits of software patents.

Let me be clear (as I am in the post): I don't like software patents. I think they should be eliminated. And yes, I realize the term "software patents" is vague, but we could work through that.

BUT...we're not going to eliminate software patents any time soon. My post is an attempt to offer practical advice to folks in the here and now.
That's a straw man. The parent comment was equating a poor grasp of English with a poor understanding of American law, not with low intelligence.
Loved the story, and also loved reading notes from Aaron and David. I would just like to say that I, for one, do want Microsoft Office on the web. I use Google Docs all the time whenever a client sends me something Excel or Word format and I need to work with it. I use Google Docs to create sets of user instructions and save them as PDF, to create quick diagrams, etc. Google Docs surely lacks many features required by a good word processor, but thus far I've been able to live without them, and live without installing an office suite at all.
