Wolfram Alpha also seems to bail out when a mathematical expression exceeds a certain complexity, which makes it fairly useless for the only thing I want to use it for - evaluating hairy integrals and other long expressions. Or worse, it just "interprets" it as a part of my original expression and calculates that, as if I just typed out the rest of it because I enjoy typing random symbols. It seems like such a waste to fire up Mathematica every time but I haven't found any comparable online tools.

I think W|A could have been a great tool for this kind of thing but instead it tried to cover every subject instead of doing one thing well.

Jerry,

That is a great question. Personally I think Plus was a huge blunder. Steve Jobs recognized that PCs won the war. He saw that growth was in mobile and tried to build the best mobile device. #Winner.

The main thing keeping people at Facebook is that everyone you know is there. And it's decent enough. But if they start to screw up, people will switch and not miss it. Just watch reruns of comics unleashed. It is jarring how everyone talks about their MySpace page, then listening to commercials advertising Facebook pages.

Search on the other hand is harder to switch or copy. Yet Google is squandering their core competency. I'm on DuckDuckGo. Many other techies are. And that's where it begins...ask Yahoo...

Page listened to Jobs about focus. But he should have built something innovative. Go where the puck will be. NOT where it is.

Google hires PHDs. Their employees are a poor fit for a PLUS-CENTRIC company.

Great post. Vectorization is one of the easiest ways to increase per-thread performance.

This gives me an excuse to post one of my favorite articles at Intel. It shows the best performance increases for this person's problem come from optimizing memory accesses.

http://software.intel.com/en-us/articles/superscalar-program...

Seeing as memory read/write instructions are about 40-50% of the x86 code out there (from what I've heard) tweaking memory accesses seems to be a great way to get great performance.

The loss of user agent control is a serious problem independent of whether or not a malicious request is accepted. The fact that the user agent crafted and sent the malicious request at all is a problem worth solving. But for some reason you either seem to believe that it doesn't matter that the UA is acting maliciously on users' behalf, that this is an inevitable consequence of the way the internet works, or that it's such a difficult problem to fix that you'd rather ignore it and focus on the server-side. Or perhaps both.

Personally, I don't believe either of those things. Server authors should certainly take point on battling CSRF. But there is an important client-side piece to the puzzle that cannot be ignored. If users cannot even prevent their own browsers from attempting malicious actions on their behalf, then there is something critically wrong with browsers.

Hi Ycombinator!!

I'm a 12 year old. I wanted to ask if there were any intern opportunities for me. I know that I'm really young and you may not offer me any but I'm a very hard-worker and I'm also learning web-based programming (I built an educational site). I would love to help and I would also learn so much from coming there (I'm going to intern at flutter next week). And for anyone else that reads this, can you give me any reference or opportunity? I would really appreciate it. Have a nice day!!!!
Also, Paypal is free for personal transfers if you have a bank account hooked to it, even past $1000.
I hope it works better than people search. If they're not in your friends list already, good luck.
That's 9 years.

I've used Ruby for almost as long, and on MRI at least, I can't think of anything as significant. (JRuby FTW)

Think of c#'s evolution. Ruby's. JavaScript's. SQL's. 9 years isn't exactly blazingly aggressive, but in the context of a programming language it's not eyebrow raising either.

I think generally that's a good thing.

The techniques Ewan outlines are spot-on; my clarification is for people to have the right expectations of the Micro's, not on the information he provides on tuning a WordPress install.

That said, Smalls and up on EC2 will give you more consistent performance (they aren't built to provide the spike-performance Micros are) BUT are still relatively subject to "noisy neighbors".

The smaller the instance, the bigger the impact felt; it is still possible to have a small grind to a halt because of a noisy neighbor and typically I do not see people hosting web front ends with smalls because of the erratic and poor performance (in general). Possibly a fleet of them behind an ELB, but even then I see Mediums and Larges much more often as the "web server".

The mediums provide an awesome (and typically unsung) balance between monthly cost and performance on your way to a large (which can get quite expensive).

I spent 2 min looking at the site, and I can't visualise how this would be easier to create or consume than screencasting/screenshots. I'm sure it is, but could you work on making that clearer.

Btw when I first started reading I thought you were creating a human-curated directory of tutorials like Yahoo was for web pages in the early days. I would definitely use that. But its obviously a very different problem you're solving.
"The fastest growing company ever" can't get its book right? Shocking.
The problem really isn't with a particular component in Java. The problem with Java is, Java came as a quick relief to people who had problems with managing memory themselves. Java solved what seemed to be the most pressing problem at that time. Times have changed, today I have completely forgotten some thing called as 'memory management by programmer', today its a given that a modern language today should do that by default.

The problem with Java today is how big and bloated it has become while it doesn't solve fundamental problems programmers face. Its growingly becoming impossible to program in Java without an IDE. Only Java ninjas can probably program Java with a Text editor. Its XML mess all over the place.

Now it takes several tens of lines of code to do trivial file operations and other trivial tasks. This problem was long solved with languages like Perl and Python around 20 years back. Its almost two decades and Java still hasn't caught up. There are still no practical lambdas and good functional programming capabilities.

The issue is something like this. By asking everything to become an API of some sort and writing so many method calls both my unit tests and exception handling code bloats like crazy. My eyes cringe every time I open a Java class file and nearly 60% of the code in there is either try/catch statements or some form get/set methods.

The code to boilerplate ratio is too high. And it just doesn't feel like a language that belongs to the 2010's. Java and its community also promotes heavy use of XML's often used as bad replacements for RDBMS, this leads to building of small buggy and wrongly built DSL equivalents of small parts of SQL all the time.

The path from now is not the make the language bloat like crazy and then provide IDE's to handle that. It is to make the language syntax intelligent enough to take care of many problems you have to other wise worry about. If you see the whole concept of Lisp and other extensible languages like Perl are all about. To provide forms of extensibility that solve the code scalability problem.

And lastly and unfortunately the Java market is full of substandard programmers whose life begins and ends inside eclipse.

A manager or a pointy haired boss might prefer Java for hiring cheap programmers and the 'Oracle factor'. But Java is dead for Start up's and other sexy glorious projects.
This is not true. Unfortunately, I can't elaborate further.

Sounds really cool. I like services that offer solutions that are easier along the dimension of horrible-awkward-interactions. I.e. I think that maybe the biggest appeal of this is not actual the time saved finding the person at a time when they have the right cash on hand, but the fact that Mint will send the email for you in a clean, impersonal but not menacing manner.

I haven't tried this or Venmo but I think it would be cool if they added some sort of group portal service, where you could email a group of friends, say for "Dinner: $96", and then Mint would email all of them with a link to a spreadsheet/form of some kind where they could list what they've already paid each other, other related grievances that would affect how much they owe, etc. And then once all had approved the resolved list of payments, the process would proceed on an individual level as normal with the correct amounts.

Ah ok, gotcha. I personally know a bunch of very successful guys and gals both, so maybe you just need to meet a wider variety of people. I've mostly lived in urban areas (Boston, NYC, Silicon Valley), though, so that probably skews my own sample pretty badly.
Extremely interesting.....a few questions that come to mind for me:

1. Is it worthwhile using for simple flights? Ie: Toronto to las Vegas, direct?

2. Can it handle extremely complex (maybe even almost freeform) scenarios beyond the displayed +\- x days, such as: I have 14 days available (but would settle for an 11 day trip), and I can take travel any time between these dates, and I am willing to travel to a, b, or c - what are my options? (This is getting into the realm of travel agent services....for which I would gladly pay, assuming one might actually be able to find a competent one through this site).

3. Does the service tend to work much less well in Canada compared to the US?

4. Is it conceivable that if this service is successful enough (market penetration wise), that some of the optimizations used may start to disappear, or affect pricing from airlines?

5. Any plans of extending it to vacations (flight, hotel, all-inclusive)?

6. You mention frequent flyer plans on the site - for a person who has no clue, any (long term) plans for offering sign up for those types of things integrated with your service?

7. Are you running some customized search tools in house, or does each person fulfilling contests just using their own secret tips and tricks?

Good luck on this, truly one of the most interesting initiatives I've heard of in a very long time!

The $30 billion Social Security hack

--------------------

Sometime last year computers at the U.S. Social Security Administration were hacked and the identities of millions of Americans were compromised. What, you didn’t hear about that? Nobody did.

The extent of damage is only just now coming to light in the form of millions of false 2011 income tax returns filed in the names of people currently receiving Social Security benefits. That includes a very large number of elderly and disabled people who are ill-equipped to recognize or fight the problem. It’s an impact pervasive enough that the IRS now has a form just to deal with it: Form 14039: Identity Theft Affidavit, December 2011.

The Wall $treet Journal has a story about this problem specific to Puerto Rico, but the Journal fails to mention that this is a national problem — a $30+ billion problem.

The story is going public now because tax season is upon us and there’s no way to keep it under wraps as people file their tax returns only to learn that a return under that name has already been filed with refunds paid electronically into a bank account now closed. The December date on that IRS Form 14039 shows the Treasury has been expecting this for awhile.

The question being asked about this in Washington, DC today is whether this hack was an act of war? More likely an act of Tony Soprano, I’d say. If the goal of war is to sow confusion and discontent, then okay, maybe China or Iran are behind this (you don’t have to be a superpower to take on the U.S. government anymore). But the more probable goal is simply to steal money and that’s a domestic job.

Either way, that big hacker score guys like me have been predicting for several years has finally happened with draconian policy changes sure to follow. Lucky us.

Not sure if this is worth the effort, but brilliant approach to learning. I've often had fun playing with inventing my own alphabets and stuff -- if you could actually learn to read this font at a decent speed, it would be fun to click a bookmarklet anytime you wanted some privacy :)

I love reading, and I read pretty fast - I've often thought that the existing approach in most textbooks where they give you a short (5-10 line text) with tons of new words and grammar, and then when you're done working through that, give you a new one with a ton of new words, is non-ideal. Once I'm done learning all the new words, you should give me five pages with text that only uses the words I've already learnt, to "fix" it - and to give me a feeling of mastery...
Would a prime-based number system work?
Is it possible to do a positional numbering system where, instead of the positions being powers of some base, the positions were the "next" largest prime?

Would such a system have any advantages over existing number systems?

To be annoying by tacking a long, overly thought-out comment onto yours (sorry): Agree with this root sentiment, for many other things that used to be done casually and amicably in real life and are now replaced by process-driven, efficiency-focused and sterilized online versions. However I think that such a substitute is ok, or better- great, when (a) the thing just wouldn't happen at all in the first place because it's just too difficult (e.g. say keeping in regular touch with a very large group of far away friends) or (b) it's not pleasant in its real-life instantiation anyways. I think nagging friends to pay you back esp. for small amounts satisfies both of these criteria.
Very interesting thoughts!

a = 10;

a == b; // true

a = 1000;
b = 1000;
a == b; // false

11 years in LA here. The traffic is awful around rush hours, worst I've seen anywhere outside of DC. But off-peak can be fine. And, honestly, you just get used to it. You take it into account, everyone else takes it into account, that's how it is.

The sprawl isn't as much of a factor as some might imagine. You tend to stay within 10-15 miles of home anyway, so it doesn't matter that there's another 50-60 miles of sprawl beyond that. Besides, it's not like SV is sprawl-free.

LA is much bigger than SF, and that's mostly a benefit. More options for most everything.

As far as dating, just avoid anyone in any way connected to entertainment and it's fine. I'm sort of kidding. Sort of not.

It's cheaper than SV, for sure. Though the upper end can compete with the upper end of SF as well. It's a city where you can spend as much as you'd like, there's not really a ceiling.

Los Angeles gets a bad rap culturally, but in reality it's second only to New York in just about any cultural way you'd care to name. There's a LOT of creative people here in just about every creative arena.

One thing I really like about LA is that there's probably more people trying to live their wildest dreams than anywhere else on earth. I think that's admirable.

Biggest downside? Weather. I hate the lack of rain. Something I hear a lot from people who are from elsewhere. Summers are quite tedious.
You are not getting it, Perl 6 is not designed as a successor to Perl 5 but as a Age proof Perl.

Think of it like pg called a hundred year lisp language. Perl 6 might be the age proof Perl language. When you have such and ambitious goal the time taken is worth to fulfill it. Larry wall figured out quite a while back evolving Perl 5 may fix some warts but it won't solve the larger problem.

The larger problem today is doing language extensibility sane-fully. There are no C based languages that are as much extensible as a Lisp based languages. Perl 6's larger aim is to solve that. While retaining the 'Perl factor'.

Re write is inevitable if you have to solve this problem, no matter what joel says you have to rewrite a few things to fix them. The incremental path is too slow and you will loose out on time while somebody eats your lunch.

Perl 5, Python x.0 and Ruby x.0 series are all great languages but eventually on the very long run they will be plagued with the same technical problem every language runs in to. Providing sane ways of extensibility without bloating too much.

IMO Perl 6 will do well, for the same reasons Lisp has done well.
