I'm curious about what field of scientific computing you work in. I am only familiar with MPI and hybrid MPI/OpenMP codes. I haven't come across any OpenMP only programs ever in chemistry or physics.

If you have a loop with independent iterations then you can use message passing or shared memory to approach your problem (as well as loop vectorization). The main problem with message passing is that for very large datasets you can run into memory limitations.
I just returned from San Jose back to Toronto. After spending most of the past week there, I can honestly say, NOTHING happens in San Jose.
You don't even need the hi-res images -- keys can be copied from afar using telephoto lenses and the like: http://www.jacobsschool.ucsd.edu/news/news_releases/release....
I'll be flying in from Toronto.
I'd pay $100. Mainly because I feel no desire to get one. I can think of a couple things I might build with it, but after that, what would be the point?

Call it a failure of imagination on my part, but imagination can be stimulated by inspiration. I haven't seen anything remotely inspiring about home 3d printing so far.
This printer uses photolithography vs FDM used by reprap and makerbot - it works by using a laser to solidify photopolymer. These printers are capable of very high resoltion, but the downside is that their substrate can cost hundreds of dollars / liter.
In college, my friend (who was by no means an expert) picked the lock on the elevator with a paperclip and a shim. These "locks" are only designed to keep out the honest people.
Just to clarify, the Nexus devices (NOT built by Google) get aee quickly upgraded (with a few exceptions on some carriers). Motorola (now a part of Google) continues to be the worst at upgrades.
Read something really simple, informative, and beautiful created by Google. Go to Hacker News to read people bitch about how they'd have done it differently and better.
If we understood that we'd be better off I think. It is a classic drive by commenting, comment created 18 minutes ago and account created at the same time.

It would be interesting if accounts were sort of pre-hellbanned where they thought they were commenting but they weren't visible until may the third comment in as many days. Then they could become visible or something.
That giving the PUA what they want will make them happier.
Um, yes. It doesn't have to be fraud to be wrong.
I'm not anti-trade secrets. In your scenario, the source code to Half-Life 3 is a trade secret that the Valve employee is obligated to keep. However, if the code is ever made publicly available to read, it's no longer a secret and no money should be made from selling or licensing it. And even if the source is never public, once binaries are made public, it should be perfectly legal to reverse engineer those binaries.

In a no-copyright world, Valve's business model would certainly have to change, but your particular example would work mostly the same as it does now. The major difference is that you wouldn't be able to make 50 million dollars. Once those levels were released, people would be able to share them freely among themselves. Only the first person has to pay the $10, which means if you're willing to pay a million dollars for illegal access to secret source code, you should probably have a better plan for what to do with it. =P
Team Password Manager from Baltimore Startup Weekend
Safari could be doing more in allowing webapps to function like native ones- it has the full screen, add to home functionality, but it's not well understood or known. There's no way to register protocols to launch a full screen web app, and a series of hacks are required to stop the entire app doing the elastic "bounce" when you scroll the wrong way.

Safari is good, but it could be a lot better. But I'd expect Google to be leading this charge, not Apple. But Android has basically zero integration options for webapps.
Neat.

Bug report: It seems to misshandle addresses that are ambiguous by cardinal direction. ie. "123 Some Street N"
> "All of our analyses controlled for graduate/sibling status, age, gender, and the interactions of these variables, as well as the first three principal components of the genetic data from the full set of 90 genotyped SNPs (to account for possible population stratification)."

It is customary to do genomic control using likely-uncorrelated SNPs (i.e., excluding the 13 SNPs nominally reported to be in LD with the trait of interest). That they included these 13 when estimating pop strat from a small overall number of alleles makes me concerned that they may have unintentionally "controlled for" the actual effect, if any did exist.

Even then, since they controlled for the first 3 PCs of that data, and I would assume the 13 candidate SNPs to be in linkage equilibrium, they shouldn't be getting rid of more than a couple actual associations, yet they find none replicate. So my observation is probably just a curio.
The 1996 act was completely undermined by telco lobbying. Its public policy purpose --legislated disruption-- was never successfully implemented. They won the war you never knew was fought, the greatest type of victory. The subtlety of the argument is precisely the point. =]

There is a reason the most $$$ paid man in washington is the head of RIAA, the hollywood/old media lobbying group. The Cable and the RLECs (now VZ, T, etc) are all-pro and in the same leaugue.
Look, if you use Opera then that's awesome. You have your reasons. It's got a lot of users, and that's also great.

But developers reasonably make decisions about which browsers to optimize for and which ones NOT to optimize for. They're not insulting you for your browser choice: they're just being reasonable about how they spend their time.

We should always be open to new things so I won't sit here and say "you should just use Chrome because it's awesome and incredibly fast", and if they're differentiated enough they'll become standards everyone supports. Opera is not. And you're not a martyr.
Wrong side of the street, otherwise great.
I'm a Kickstarter backer of this; I have the original Makerbot Replication, and decided on this instead of Makerbot's 2.0 version due to the higher precision (25 microns) of the Form 1 version.
Submitter here. I just stumbled-upon and liked it. The original developer is http://www.hansnauta.com
Current cost for the Form 1 substrate is ~$150/liter.
LinkedIn is the obvious answer.

Anyone got it working on iPad? It seems like nothing is moving on the map. Maybe Japanase servers have a long Round-trip time, I don't know why.
How browsers work
I'm unclear on what their API would allow, but I think that there is a huge opportunity to present the important stuff on Facebook to users in a cleaner, more elegant way...we've seen so many attempts at cleaning up the inbox; I'd be interested to see someone focus on the News Feed.
Protip: don't try this in chrome ... the endless auto-translation of the bubbles (which happens each time a train moves) kills it completely. Looks decent in Safari though. Pretty neat!
He makes it sound like nothing happens there, but if so, why do they claim to be the capital of SV?

Geographically, San Jose is much closer to the "heart" of the valley -- Sunnyvale, Cupertino, Palo Alto, Mountain View and the surrounding areas -- than San Francisco is.

It is also, going strictly by population, the larger of the two cities.
Warning Signs: Obamas Tyrannical Executive Orders
Not being able to turn of my alarm this morning certainly was refreshing !
Was this not renamed to Persona which hit beta recently and posted on HN serveral times already?
Would have loved to get a "push" notification from AAPL regarding this..

Seems like Apple is no longer signing the iOS 5.1.1 ipsw -
this is ridiculous..I was hoping on downgrading to iOS5 before hawking my 4S to Google Maps grovelers.

On another note..I cannot restore to my iOS6 (beta) backup with the real iOS6..thanks Apple!
RailwayJS
offtopic, but because I disagree with the HN policy of not informing people when they've been banned I'm posting this.

iRobot, your account has been banned for over 100 days. Unless someone turns on the "show dead" switch in their profile, they can't see what you post.
I know it's a different use case but the OP is talking about using a strong static message and having faith in the user to scroll below the fold...all the while as his website uses an animated popup box to fill the bottom right area of my screen...twice (on the iPad). So apparently, there's a case to be made for some kind of obtrusive moving elements...

As someone already said, I'm inclined to agree with the OP. But there needs to be hard data here. People often won't know what to do (I.e. scroll down below the fold) until you flash some hint in front of their eyes. Newspapers used to do usability studies on their print product quite often...and they always found that a huge number of people, no matter how compelling the story, did not turn the page. I can see a case being made that even if there is one big thing you want to get across to the user (such as a bug sale), there are often competing concurrent interests that would be missed below the fold. At least a carousel gives that item/module a fighting chance to be just noticed.
The key set isn't the problem, that apparently you only need five keys is. Having secure keys is at least as important as the security of the lock, and a single key shared for the entire city isn't that.
Where do you get the data for the location of the trains? Is there some kind of data feed?
What would make sense is making helmets mandatory for road bikes, cyclocross bikes, mountain bikes and touring bikes. All other bikes aren't really designed for speed or unsafe maneuvers and therefore shouldn't require helmets.
File under shit happens and move on. Nothing to see here, people.
It's real-time in the sense that it's based on the published schedules of the train lines, but it's not "real" real-time because it is not based on the actual locations of the trains.

It's not useful at all, but it's a cute visualization and because trains in Japan run very nearly on schedule during normal operating hours, it will be mostly accurate the vast majority of the time.

edit :
In the "About this site" link on the upper right, it explains that :

① The site uses the scheduled operating information and displays the location the trains are running on the map at the current time.

② The contents, URL, etc., can change at any time or can be made no longer publicly available.

③ & ④ The site adminstrator takes no responsibility, etc. You are responsible for your own actions.

In the other information section, the author specifies that it's for Japan only and that the icons used are representative for those lines.
You comment and m0nty's about Specialized brand helmets meeting a stricter standard prompted me to do a little helmet research. I was a bit skeptical of the slim Bern helmets. I think simple physics demands that to stop a moving head on impact slowly enough to avoid concussion, one must use a (dorky?) a "spaceship on your head" helmet. There's no getting around that to go from velocity v to 0 without accelerating more than some threshold time requires a certain amount of space.

Now, I don't know if the thresholds chosen by ANSI or Snell or whomever will make a real difference in a crash, but Consumer Reports rated Bern helmets poorly in "impact absorption".

What specifically do you find evil?
Don't forget to mention that dooring isn't really problem in European cities. Most European cities separate the bike lane from parked cards. For people in bike lanes, that's the main risk that would cause an accident where a helmet would help prevent injury.
I don't think cheap and light are fair points there. Sure, it could be worse, but no helmet is definitely cheaper and lighter than a helmet. (aside from possible medical bills, but I feel that's covered under the 'keeps you safe' point).
looks great on IE9 as well :)

One is apologizing for an actual issue with the product (however severe it is or isn't). The other is apologizing for the "issue" that the product became more affordable. Perhaps the difference in the substance of the complaints has something to do with the tone of the responses to them?
Coursera seems to be beginning to disclose their business model: I just got an email from them advertising their placemant services.

Holy hell, this brings back awful memories of back when I was a software engineer working for a large consulting firm.

The biggest problem with working in non-software companies is that, software engineer salaries are treated as overhead, not investments. This means that they aren't going to spend tons of money to hire the best and brightest talent, they are going to hire the cheapest labour that can get the job "done".
Major Outage Prevents Purchases on Apple’s iTunes & App Stores
I've gone while I was in high school.
As of 12:30 AM EDT, can't download, update, or restore anything on iOS or Mac.

D'oh!
It doesn't block page transitions on all of the assets on the next page loading. I click the next button and get to wait 30 seconds while all the images show up.
For me, my iPad 1 still makes a plenty good Instapaper/Kindle/email/writing/basic web/casual gaming device, and my only major hope is that developers like Marco don't drop iOS 5 support way too quick for their apps.
ITunes bug prevents new app downloads. May not affect non-US accounts
It's true. Around Boston, the bike lanes pretty much exactly designate the zone in which you are at risk for dooring.
Yes, I work on FB apps that span multiple types of devices. You are correct in that only android users will see the request. I don't see it working all that well for you though, because the requestor won't know which friend uses android. So the requestor might need to send twenty requests to hit one friend with Android.

Obviously, it is better to have an app that spans all the devices. That way Android users can request to iPhone, who can request to mobile web, who can request to canvas. Personally I think it is so important to be present on all of the devices that it is better to have slimmed down apps everywhere than one good app somewhere.
likewise if I can get it together... should do a NYer meetup out there, or before/after in the city

So presumably it's compatible with any RFC 4226 / HOPT (https://tools.ietf.org/html/rfc4226 http://en.wikipedia.org/wiki/HOTP) implementation?
At what point will we be dropping the '5' and just referring to it as 'HTML'?
After repeatedly cautioning readers to be polite in correspondense, the blog post ends with him calling the plaintiff a "religious nutter".

To me that contradicts what he said earlier about being polite, and cheapens an otherwise good article.
>but it's not "real" real-time because it is not based on the actual locations of the trains.

It's "real-time" enough in Japan because trains in Japan are almost always on time.
The Genius of Design
I was amazed when I learned how many people in Germany have all-access keys to apartment buildings (learned this when my bike was stolen).
I suggest the community downvote comments like this. I'd like to see a published community guideline encouraging people to not make meta comments. The vast majority of readers don't use Opera, and a personal quest to see Opera treated as a first class browser doesn't belong in this thread.

This is a cheap and easy way to score points.
Definitely unethical.
The reason to buy says, "over half a million subscribers save hundreds a year". This statement could burn them in court if proven to not be a factual statement.
I would surmise that it could be shown that the half a million subscribers paying $480 a year each, (240 million total) may not save hundreds a year. The least they would have to show for a forgiving jury would be that subscribers saved a total 100 million in personalized boutique purchases and general shipping. A demanding jury would require 340 million in savings. I would wager that argued by a savvy attorney the statement could be read as a misrepresentation in advertising. It would also be based on how it read at the time of original subscription, so there wouldn't be much value in changing the statement now and only provide more validity toward it being a misleading statement. The defense would argue that people read the the info on the right, understood the terms and checked the box in agreement. The prosecution would argue that the claims in bold of so many saving so much resulted in more making the purchase, which was a false misleading statement.
Sales people make these types of claims all the time over the phone or in person to get a sale, putting it in writing is a huge mistake, and online retailers shouldn't be so brash.

First, it's Google we're talking about here, not some cash starved startup.

Second, you seem to have not completely read my post. It was more about the "update" and "upgrade" language. How would people on Linux feel if they tried to download a program and and it told them to "upgrade" to Windows to get it working?

>"We should always be open to new things so I won't sit here and say "you should just use Chrome because it's awesome and incredibly fast"

You should try Opera, it is awesome and incredibly fast :)

>and if they're differentiated enough they'll become standards everyone supports. Opera is not.

What is not differentiated enough and Opera is not what?

Opera is pretty good at following standards, it's no IE for sure.

Again, it's okay if web developers don't have the time to test and support Opera, just don't tell its users to update or upgrade to other browsers. Even "Best viewed in Internet Explorer" is less condescending We didn't get rid of that and Flash to end up back again in this browser sniffing mess.
This is false - there exists a class of apps where all they do is have a well tuned requests funnel (seriously, that's all the app is), and they are alive and well. See e.g. the MyCalendar franchise:

Yeah, that's fair: I'm lumping legitimate criticism and reasonable UX opinions in with "hating", but I'd bet for the guy who put his technical heart into these things, the short, unqualified (no "hey, cool stuff!") criticisms are tough to swallow.

I was surprised that Bootstrap didn't have these from the get-go, so I'm going to say, again: hell yes. This is practical, useful development that will make a lot of apps better.

Train was 8 minutes late this morning and 3 lines were stopped. Probably due to the Typhoon yesterday causing scheduling problems but even on normal days Japanese trains are not the paragons of time-keeping the west seem to make them out to be

(Although they ARE miles better than anything I have seen in the UK for instance.)

[EDIT] Note: Previous poster downgraded the conviction of his statement after this comment was posted.
This is really cool; a few years ago I wanted to do this for the published schedules of NYC's subway. At the time it involved scraping schedules from the MTA website's horrendous HTML, but now it looks like they've completely reversed direction and have it in an accessible format. Interestingly, they have real-time data for buses, but not for the subway.
Why do you think Opera is a second class browser? You should upgrade your browser to Opera sometime.
Grain of Salt: I'm not an expert by any means.

This is really cool and interesting, but I have to also admit to being deeply skeptical. I'm going to try to read a lot more on the proof, but it seems incredible (in a negative sense) that transfinite induction could prove that a finite number of operations suffices for anything.

Similarly, "computable" and "transfinite" would seem on their face to never belong in the same proof.

Obviously I don't have the math background to make any claims, but right now I can't convince myself that this could possibly prove what people claim it does. (Edit: Or maybe a better way to state my objection is, it seems to me like the axioms one would need to accept to prove this might not really make sense when trying to describe computable systems.)
I recently posted about this problem and created a solution for users who dont want to get spammed.

Honest question: what can average people use 3d printers for realistically? Every time I read more - I want one. But then I try and figure out what kind of thing I'd print. Besides custom chess pieces and my own Legos - am I missing anything? Or are they just for engineers, "builders", and architects.

I know they're expensive now - but lets assume they come down to ~$500 (price point where tablets took off).
I were planning to make one. But then I found this. Afaik, many apps should be made using html. Btw. I would like to see TOTP mentioned instead of Google/Gauth. But I assume Google something is much cooler than anything else. See: https://en.wikipedia.org/wiki/Time-based_One-time_Password_A... - So it's generic TOTP implementation, not Google(only) Authentication app trusting Google infrastructure. Also, there might be local storage security issues with HTML5 apps, but I'm not expert in that field.
The price I am prepared to pay can be significantly altered by the avaliability of models to print. At the moment I would pay about $250. I've checked through http://www.thingiverse.com/ and have seen a few trinklets that would be fun to print out. My son would probably get a kick out of it. But without content I wouldn't consider spending much money.

However, if the right content was avaliable, I would be willing to spend up to $2500 on a 3d printer.

What is 'the right content'? At the moment, I don't know! 3D printing needs a 'Killer app'. I'm waiting for the 3D printing equivalent of VisiCalc...
"Was"? Where can you find one at the $500 mark?
Materials for stereolithic 3D printers, like Formlab's, cost 4 times, from what I've heard, as much as conventional 3D printers.
