German teen Shouryya Ray solves 300-year-old mathematical riddle posed by Newton
The most sensible comment I have seen on HN for quite a while.
Thank you!
Beware: things in NY may get mighty cold if the social bubble pops (eventually they all do). Atlanta was a great place to start incubators during the dot com boom. Less so after. Many of the startups in NY can't get to real revenue fast, so if VC dries up things could get very bad, very fast.
It is well known that low weight, high reps lead to an increase in endurance, while heavy weights and low reps (as in 4~6 repetitions leading to exhaustion) lead to hypertrophy i.e. muscle growth.
Thanks for your insightful comment. I'm glad to hear this, as I am a BB fan as well. I haven't often used the other platforms, but what I've read in online reviews, the BB is still the king of email. I literally get email faster on my blackberry than in Thunderbird or the Google Apps web interface. Battery life is also stellar.

I'm looking forward to BB10, and plan to buy one when they are released in October. I hope they make the ship date.

Regarding the Playbook botch, I read recently that the reason why the Playbook had to be tethered to a phone to get email and BBM was because the RIM infrastructure only supported mapping an email account to one PIN. Have they corrected this? I understand if you're not able to comment for legal reasons.

Can you tell us more about the advantages of QNX over iOS and Android? Have you tried the Cascade SDK? Did you get your hands on the Dev Alpha?

Oh my god. I just realized what it feels like to be a fanboi. Oh well, RIM needs love too!

if you're interested in visual programming environments and try to look up prior efforts at all, you WILL find this sentiment to be true. It's somewhat depressing actually. You'll not just find all these cool sounding environments from the 80s that seemed light years ahead of today (or even something like Light Table), but you'll also find studies on the difficulties people faced with them and why they failed.

Text is not an easy thing to dislodge from the programmer's toolset.

My personal opinion keeps switching between "Text is basic and elemental, so it's the most natural way to represent code and therefore is the preferred" and "We havent built tools good enough or representations revolutionary enough (or scalable enough) and that's why text remains preferred".

I can see how someone who's built a non-textual programming environment can come to a "been there, done that" kind of attitude. Just take his enthusiasm at new attempts at the problem as a more pertinent response and ignore the rest.
I think at one point SV had 10x more capital than NYC. The difference is slowly decreasing.

(I moved from NYC to SF to start a company.)

Another big reason I see that NYC will catch up is that you just dont need that much to start a company. And also VCs are beginning to have offices in both areas.

The only real difference is the ease with which you can meet someone really important in SV. You can get an introduction to PG through one of his startups within the week if you can show you have some traction and get the respect of some founder he has backed.

And all said and done, startups are realizing that investors dont matter - creating a product that people want to use is the bottom line. If the costs are low and you can afford it, you might as well forget about having to deal with VCs and investors except for advice.
The program itself is more interesting than the gimmicky app:

Ok, was confused by the post. Thanks for the downvote!
Same thing happened to me.

Bought latest Lightroom a month ago directly from their site, and it took 3 days for them to acknowledge the purchase and give me the license key.

Very odd.
My company uses volume license keys. It takes at least 24 hours to get an order filled, usually more.

Of course, if you are only adding extra licenses onto a key you already have, no big deal.

In any case, it's inexcusable. But that's what you get with a monopoly.

That's a very creditable bytebeat version of the THX Deep Note! I recommend:

• Putting a couple of spaces before your formula so the markup processor doesn't chew it up.

• Using Darius Bacon's bytebeat player instead of the old Wurstcaptures one: http://wry.me/bytebeat/?code0=((1000%2F((t%2F12)%25(t%3E%3E1...

If you want to approximate the original more closely, I think you might need sine-wave oscillators rather than square waves. You can get a pretty decent bytebeat sine wave from http://wry.me/bytebeat/?code0=((t%2615)*(-t%2615)%5E!(t%2616..., but most of the time I use a triangle wave instead when the standard sawtooth is too harsh.

I'd like to point out that your bytebeat isn't actually using bitwise operators in any non-arithmetic way; it's equivalent to http://wry.me/bytebeat/?code0=((floor(1000%2F((t%2F12)%25flo..., and in C you can leave out the occurrences of "floor".

Presumably you have the auth flow in the new tab finish on a simple page containing a script. What does that script do to notify the original window that the auth flow is finished?
1) Is it toxic?
2) Does it affect the flavor in any way?
3) Have we forgotten about the existence of plastic squeezable bottles?
That is a blatantly false dichotomy. You wouldn't use a browser that did not let you access potentially malicious pages at all, but you wouldn't want one that gave you no protection either. And so you run Chrome which gives you a scary warning page but lets you go see any page if you really want.

I really don't buy that Apple's absurdly draconian control is better than something akin to Chrome's warnings. You should make it difficult to install something potentially malicious by accident our without thought, but you should definitely not go out of your way to stop determined	users from installing what they want either! Apple goes well beyond the reasonable and helpful and into the absurd.
No I do no answer and usually ignore. But they still keep calling. I think it could be an automated robo call ?

> And that magic knowledge you take from... where?

Studying the viability of, of all things, solar power, and comparing the costs of various competing technologies. (The school I studied at is quite involved in solar research. It's price needs to drop by a significant factor before it becomes competitive, but it's on the way.)

> Bullshit

To borrow your words: "And that magic knowledge you take from... where?"

When you design a reactor to take the rather substantial internal steam explosions (and the associated water hammer) that might happen in a complete failure scenario, you end up with quite a solid building.
This one's been making the rounds a lot recently.. that said, I am curious about two things:

Firstly, the edibility of this stuff. I know they said they only used food grade things, but really that won't go anywhere until it goes through the insanely expensive FDA approvals process.

Secondly, if it'll catch on. I can see marketers running wild with this, but on the other hand I can see companies have a vested interest in you not using all of the product you buy.
Mice suck[2].

2. They are fine for detail-oriented, fine-motor-control work. Coding is not one of those.

As someone who has written tens of thousands of lines of code with only a mouse, I would modify this statement to "Mice suck when you are primarily using a keyboard." Editing code is detail-oriented, fine-motor-control work, and in my experience a mouse is better than a touch screen for editing (with current interfaces), and worse for typing code in. I have not done any coding with a keyboard for many years, so I can't directly compare, but I think mouse, with my custom typing system, is easier for many situations. The problems come when you are using both mouse and keyboard.
And the missing 'other' 100% is getting anyone to take notice!

One can have the most wonderful, state-of-the-art, mature product - that remains largely unknown by the 'majority' because... well, why?? I still can't figure out this last bit...

(Modern Smalltalk is, unfortunately, a perfect example of this.)
How Not to Start a Hosted Service.
This is awesome. Thanks for posting it. However, may I suggest changing the title to "The THX Deep Note"? I thought it was going to be about the sounds my father-in-law and George made for their movie THX-1138, the namesake of Dolby THX, many of which sounds were reused in better-known movies later, such as Star Wars.
Perhaps, but how does evidence handling work when it's of crucial importance for the defense?

"If the stock market picks up again I think that the tech scene will start receding."

Not so sure about that. Once bitten, twice shy. I work for the man in NYC but regardless of how the stock market does, my interest in tech. and startups will not recede.
Thoughts on Government, Economics, and Society
Off-topic: By all means, charge the $99 for distributing on the App Store, but I am not really sure why Apple doesn't allow for Apple ID level verification for personal apps. Something similar to the mobile provision they use right now, e.g. having Xcode generate a binary that is associated with the same Apple ID as on the iPhone.

There's nothing false about this dichotomy, you're just setting up a straw doll.

My point stands, we tried the run anything model and millions of machines are infested with malware as anyone with any basic computer experience can attest.The number of times I've had to clean friends or families computers I cannot count. There is a very good argument for these sandboxes.
Screw ketchup. what does it do in pumps?
This isn't actually related to the defense, it is for a random Megaupload customer.
I am Gen Y and I can't even imagine myself working for the man.
Wise words.

What's the sense in spewing out endless chunks of code when no one (even the authors later on) can take the time to read it and understand it?

Why not review the code that's already been written (like the open source code Apple and other walled gardens rely on to build their systems)? This is the sort of tinkering that will help us develop alternatives.

To find the doors, and build new ones, we have to read old code, not simply write new code.
And here is the interesting thing – I mostly ignore everything else on the resumes. In other words, if I did not find any negatives, I assume there are absolutely no positives no matter what is written in the resume. Why? Because people lie. Because 80% of all drivers think they are above average. Because smart people just rephrase and embed job description requirements into bullet items of the previous jobs.

I'm occasionally called on to do technical interviews and I've also mostly stopped paying much attention to the resume, for the same reasons. I find the tendency to throw every random technology you've ever even tangentially run across onto your resume especially vexing. I've seen many people with a huge acronym soup of java technologies/frameworks totally fail at FizzBuzz level exercises. On my own resume I'm trying to limit my skill list to things I at least semi-regularly use, but I feel that such an approach probably handicaps me wrt a certain class of recruiters, so I understand why people feel compelled to list everything.
Most languages were proprietary and expensive through the 80s. When C took off it wiped out (or much reduced) the use of expensive proprietary languages. C was free so a lot of people learned it in university and wanted to use it on the job later because they were used to it. Since it was free it was easy to introduce to companies. It established a base and then when Java came out in 1995, also free but a higher level language than C, it took off like a rocket. Now the idea of expensive proprietary languages seems absurd.

Many tools have been developed that support C-family languages and most programmers depend on those tools. It's a huge job to move out of that and into an image-based language like Smalltalk because everything changes at once. That's a major reason why new frameworks like node.js or Rails can take off quickly now: They fit into most programmers' normal workflow so they are easy to adopt.

I worked in an image-based language in the 80s and it drove me crazy that I didn't have diff and grep. I was glad to leave that language when I moved on to a job that used a conventional text-file language. I'm sure I'm not the only one who found it awkward.
The short answer is yes, they are. But are better to devs that aready know the platform and have an app in development. It's not that good to those that are starting from the scratch. If you have doubts about some subject or just want to polish you app you have a good moment 101 with great devs, usually, from MS.
Fisher information is key and turns up in a lot of fundamental places. I'm currently slowly working my way through a text on Information Geometry and another on Ideals and varieties. There is only a limited time one can devote to constant learning so I try to learn things that cut through as much territory as possible. I feel strong discomfort when reading about subjects like say machine learning where a lot of stuff is seemingly arbitrary rules of thumb* .

Turns out that a bunch of geometric ideas that are useful in physics also unify ML concepts. The idea of Information Geometries. There are three ways I have seen the concept used. One is based on differential geometry and treats sets of probability distributions as manifolds and their parameters as coordinates. Many concepts are unified and tricky ideas become tautologies within a solid framework (fisher information as a metric) http://www.cscs.umich.edu/~crshalizi/notabene/info-geo.html .

The other approach is in terms of varieties from algebraic geometry. Here statistical models of discrete random variables are the zeros of certain sets of polynomials (which describe hypertetrahedrons). Graphical models (hidden markov models, neural nets, bayes nets) are all treated on one footing.

The final approach is an interesting set of techniques where a researcher abstracts Information retrieval with methods from quantum mechanics. The benefit is that you get a basic education in the math of QM as well.

* Arbitrary in the sense that you just have to accept a lot things that only become less fuzzy in time. Where as a proper framework provides handholds that reward effort with proportional amounts of understanding. The last time I felt this way was when I was first learning functional programming 7 years ago. The terminology was different and heavy going from imperative programming but I knew the rewards in understanding, expressiveness and flexibility would be well worth the effort. Confusion dissipated linearly with effort (unlike C++'s nonlinear relationship) and I knew that I was picking up a bunch of CS theory at the same time that would make learning programming (and C++) much easier.
Passed the RHCE back in 2006, at the time was spending the days (and many nights) running high end RHEL systems. Stability wise everything was great, except issues with EMC drivers and booting from SAN. These were ironed out by vendor support - which is why it can pay to have that level of enterprise support; it just depends on your environment.

These days, I use Ubuntu everywhere including here - http://hackertarget.com. It is just easier to quickly get up and running (not because its Free I could be using CentOS).

So good job Red Hat, and good job Ubuntu!
a sad day for canadian innovation :(
The app is new..the biggest complaint, is that there is no way to delete stuff. There is.. ie , swipe from left to right on an item, and a delete button appears, something I thought was pretty familiar to most iPhone users (turns out I was wrong).

Right before I submitted the app (a second time) for review, I decided to ask the user if they wanted to upgrade to the full version every time they saved a bill...I forgot to also remove the buy button on the main menu, when a purchase was made in that particular instance. The user still got the full version, but as you can imagine, the presence of the buy button made it look as if the features were still unlocked.

I'm of course working on an update to fix those..and add a few new features.
Why Crisis in Spain This Week Became More Important Than Greece
My Basic Concepts of Mathematics teacher was notorious for getting about halfway through a problem before announcing "and from here it's trivial to show...". One day he walks into class one day and addressed us:

"I've been told by the head of the department that I can no longer say 'it's trivial'. You have to understand when I say 'it's trivial', I just mean that I can do it"
<?php include("header.php"); ?>

Between the above and the huge range of existing PHP projects, I always install PHP regardless of what else I'm using.
Are you talking about this?

Empirically, you're wrong. In order to install random plugins, Firefox makes you click through a dialog that you're forced to read because the install button isn't active for a couple seconds. People fill their browsers with spyware anyway, because they want the {smilies, titties, stolen movies, etc}.

To tell the story again: my brother runs a cash intensive business that regularly moves hundreds of thousands of dollars a month. He narrowly escaped having a mid six figure sum stolen after his computer was hacked, and his solution now is to have a separate laptop that is only used for accessing the bank website and not a single other site on the internet. He's not stupid, he makes way more money than the majority of people reading this, and he finished a math undergrad with honors. And yet his computer got spyware on it that harvested the bank login. It's time to admit that our current security models have absolutely failed their users. At least on an ipad it's more likely than not that an application that will run is safe to run.
Using JQuery Functionally

Been thinking along these lines, I've been wondering how to write a very short course for people who hate school on how to research and learn stuff.
1. Quit jumping from framework to framework.
There is no silver bullet. Commit to a platform for 3 years and work through its shortcomings. In fact, the older the platform, e.g. phonegap, the more likely you'll be able to find people to work on it.

2. Innovation or revolutionary is in the eyes of the beholder. Remember Eric Ries's talk about how they rolled out 3D election chat and no one came? How about using polished mockups to learn and test ideas?

3. Leverage - tough call. Try to figure out why they are talking to you. Do you have any defensible advantage? You did say B2B2C. Do you have customer lists, like Livingsocial? Whose customers are these, your's or the businesses?

4. Do you have a repeatable sales process? Is it scalable? If you are outgunned in engineering and in marketing, then what about relationships? Some businesses don't like working with BigCo.

5. Sounds like you need mentors rather than investors at this stage.

6. 20k per month for 2 guys sounds like a very long runway. Can you vary the billing method or business model so that you don't have to worry about the 6-9 month lag? Have you considered an early-payment discount?
No dice. Still dead after < 12hrs of uptime.
Just a nitpick, but I don't believe Less is bracket-free. At least not the last time I checked.

Sass is just plain awesome.
The problem is that most of the data they seized is non-infringing. MU had something on the order of 19 petabytes; a fraction of that is actually "evidence", the rest just went along for the ride.
The Only Way to Succeed in Business is to be on Top of Things - EntreCity
Surely there's other ways to prevent that? Like making the fee one time if you don't plan to publish to the app store.

Ah well, I guess I'll have to fork over that $99 when I want to install my own apps.

Also, if I install an app with a developer account, but don't renew it the next year, will my app still be usable, and will I be able to update it?
Agreed. It just reduces friction right? Seems like it would be useful for a lot of things (like engine oil? exterior of a spacecraft?, etc.).
That is really not good. We should develop those chips at home, obviously.
Why? The Man has some really cool projects to work on with really smart people and plenty of funding, if you know where to look.
Show HN: JSON5 — modern JSON
I'm a joint Australian/UK citizen, I work in Stockholm from time to time (usually 3-6 months bursts). Because of my pattern the tax issue is a non issue for me.

I would agree with all the positives posted here. The only notable negatives I've noticed (in order of annoyance) are:

* The intrusive personnummer.
* The rental market (and the bloody laundry madness...) in Stockholm.
* Something similar to but not quite as overt as Racism.

The personnumer is used as a primary key by many businesses. Some visitors may not have a personnumer and this makes it difficult to do a range of things like visit some Gyms and so forth.

The rental market situation is a nightmare. Even worse than Sydney.

If you look like a non native Scandinavian this can lead to significant non-confrontational discrimination in some "exclusive" sub-cultures.
My understanding is the most of IV's "investors" didn't buy or otherwise provide the patents that IV uses (which does suggest the payments are closer to licensing fees than true investments). With Rockstar, we have specific players (Apple, Ericsson, Microsoft, RIM, Sony) buying the patents and funding the troll in the first place.
The swipe left to right to me is counter-intiutive, most of the apps I've come across it is swipe from right to left, and the button to delete appears on the right.

Although, testing with some apps right now it appears both ways works, but I have noticed that apps also generally include an edit button that then lets me select multiple items and do a particular action on them.

This idea stemmed from long-running frustration every time I hand-wrote JSON (particularly common for Node/npm packages and test cases). After stewing on it for over a year, I bit the bullet today and made it a reality.
