I feel the same way. It was presented to me as a great way to learn new programming languages. But really it's challenging your ability to design algorithms, and overwhelmingly mathematics-related algorithms. (I'm not saying the site itself claims anything different). It doesn't heavily challenge you to advance past a most basic level of a programming language. For example, most Project Euler problems are solved in Java most efficiently by using the features of Java that map 1:1 to features in C. You could do pretty much the entire suite of problems without even understanding the motivation of a language like Java. I did find it better as a tool for learning functional programming languages (like Haskell) however, perhaps unsurprisingly.

What we need now is more focus towards females. Men are already sufficiently saturated in the maths/CS fields. What we need is to market the idea of maths as fun to more females.

  And midgets. I'm really disappointed that Project Euler doesn't do more to motivate the vertically-challenged to excel in STEM fields.

  As a female math grad and CS postgrad, I would like to say firstly that you have successfully trolled me. I do hereby take your bait. Now for the points I would like to make, primarily for the benefit of the few who actually think as you claim to think: Women are actually similar to men in a number of novel ways. We have eyes, and those eyes are intricately connected to very powerful and compact organic computers—capable of independent thought—called brains. That's right, men and women can both have brains. And those of us women fortunate enough to be blessed with brains are quite capable not only of independent thoughts, but even decision-making. And yet another way in which we women are similar to men is that each of us, as individuals, comes to have certain aptitudes, preferences and values. Some of us, like myself, discover to their amazement that they can understand mathematics and even think mathematically about pretty much anything, and develop an interest in technology and computation because of the possibilities it opens up for mathematics and because of the ways mathematics can reflexively provide insights into computer science and programming. Other women have an aptitude/preference for: polishing nails; answering telephones; designing cute little things that men can give to women at Christmas; and so on. Are women like myself a minority? Perhaps, but it isn't because we have to be shown things like maths and programming with striking adverts, responsive websites and pretty flyers. I'm not going to pretend that society has been engineered into a patriarchy, over thousands of years, as part of a sinister plot by the Illuminati to preclude the success and independence of the children of the mother-goddess. I'm likewise not going to pretend to think that there are men with power who purposefully keep women from rising up, or give preferential treatment to male candidates for scholarships/whatever without even realising it. Because ultimately I have no proof of such things and neither do I care about some male-dominant society, because in my experience, what matters is the talent; if you have it, if you have an original idea, a way how to implement it, or if you're simply the best at what you do, you will succeed if you want to, male or female. I do not care why my boss, my clients or my investors choose me, I just want the opportunity to do what I do best, what I like doing. If you think women simply haven't been exposed to the magical and fun possibilities of mathematics and computers, think again. If women were ignorant to these fields and what they involve, they wouldn't laugh at you for being a "nerd" or date muscular/rich guys instead of you. They know what maths is, and they know what programming is, and they'll never want to visit a forum and tell everyone how awesome it was when they elegantly solved some mathematical problems or came up with a new proof for some random theorem. They will on the contrary yearn to talk about shoes, interior design, literature, art, perfume, TV shows, movies, diets and so on. The select few women who prefer mathematics/compsci and find it genuinely fun and inspiring were already posting on newsgroups, were already on IRC, were already subscribed to ars technica and slashdot on google reader, were already here; and they are already here; or they will be here in the future, or wherever else that such subjects can be discussed in the future. It is not a case of marketing the idea to a mass of women who have no idea what makes their iPhone so useful, or how their cars' brakes are engineered. Women do not go to fashion forums and tell everyone about how much I wish I could expose men to the glories of haute couture. Women do not tell their nutritionists how much they wish they could entice their male friends with raw food diets and veganism. There are the lost, unwashed masses who will never amount to anything, who will become a carbon copy of their parents and aspire to nothing beyond some repetition-of-basic-tasks job in an office or in retail, and the members of these masses are of both genders. You will fail to "market" math/compsci to these people, regardless of gender, because they cannot do it. Women who aspire to something and want to succeed do not generally want to do it with math and programming. So, to all of you who think women need to have math/compsci marketed to them: kindly stop talking crap and just ignore the gender issue. It doesn't do you any credit. Women are here. We don't typically scream that we're women because why should we? We're just professionals or students trying to succeed and learn, no different to you gents. If you want to encourage women to get into math/compsci, have a daughter and buy her a cheap laptop and "The C Programming Language" when she's young. If she takes to it, bang, she had an aptitude that would have gone unnoticed and you saved her from a life of instagram and film studies. If she deletes some system folders she doesn't think she needs, watches make-up tutorials on youtube and checks facebook every 2 hours, you know you've got yourself a typical woman. Protip: I don't think the statistics of how many women study math/compsci will be much different in the aforementioned compsci-introduced generation of daughters.

    Holy shit, that was fucking incredible. This comment made my day. Incredibly humorous and well written response.

    Hey, wanda, you got quenlinlom's remark totally wrong. He doesn't really want to saturate female's lives with more math and CS. He wants his math/CS life saturated with more females.
    - VLM 13y ago
      He's hanging out with the wrong mathematicians. Or the ladies have, um, made a judgment, and don't want to intimidate him by their superior STEM achievements. CS is a sausage fest as we all know here on HN. What most HN readers don't know is around 46% to 48% of all math undergrad degrees in the USA have gone to women since the early 80s. You can read some hilarious articles online about the "crisis" that women have declined to a mere 45% in some years. I make fun of it because my EE classes had zero female grads, everyone knows CS is a sausagefest, why I remember a decade ago in an advanced C++ class I got to work with "the" girl in the class, all true stories, but if there's one thing not to fret about, its that an office staffed by recent math grads (McDonalds? Applebees?) would have either 10 of each or at worst 11 men to 9 women, hardly a staggering imbalance like you see in CS/IT.
      - bradleyjg 13y ago
        The disconnect may be a result of what schools people are familiar with. At (Carnegie Classification) Research I universities men make up 64% of math and stats majors, whereas at Masters I there is almost parity. These university types are #1 (~8000) and #2 (~6000). Still even 64% is hardly EE at Research I (85% male), so your overall point stands.
      - jinfiesto 13y ago
        Indeed. I'm a math major, and the ratio of men to women is quite healthy.
- Kluny 13y ago
  As a woman, I would definitely use Project Euler more often if they came out with a pink version that was smaller and more ergonomic to suit my soft, feminine hands.
  - mildtrepidation 13y ago
    As a man with relatively small hands, I believe Project Euler should also have a smaller blue version that's more comfortable for me to use.

"most efficiently" Stop doing that and its a lot more fun. It annoys me when a PE problem is specifically designed to make it impossible if you do it the "wrong" way. Most PE problems allow crazy solution strategies. The bad ones only have the one true way that is computationally feasible. A few posts up someone liked problem 267. I would pick random numbers, run them, then keep the winner and make n-1 new random numbers for round 2 and keep running rounds of multiple threads until bored, remembering the best result so far. Yes, that is not a very smart way to solve the problem, but its a very fun way to exercise the heck out of your knowledge of threads in some new language. Or you could make an insane thousand thread pipeline and hope for convergence. Or a thousand processes on a parallel cluster pipelined together. Could I write my random processor using BASH to baby sit a bunch of octave instances? Newtons method at least at first glance would be too easy. Could I solve it graphically, literally, by graphing some results and doing image manipulation and analysis of the generated graphic file to obtain the numerical result and feeding back for more "zoom" detail? Totally ridiculous unless the whole point is some weird computer vision project. Given an emulator for a IBM1620 mini-mainframe from the 60s, could I write a perl script that output random Fortran-II test runs for the emulated mini-mainframe to compile and process and then another perl script to eat the virtual "printer" output of the mini-mainframe to get random run results? Problem 267 looks like a fun one to solve the wrong way. This is the unfortunate part of PE becoming popular at interviews. First of all it surely has nothing remotely to do with almost all programming jobs, secondly, "having fun while doing crazy things" is probably not the ideal IT department mission statement or employee selection criteria (although it would explain some things I've seen over the years...) The proper tool for 99% or so of PE problems isn't a programming language anyway, its octave/mathematica/parigp. So its not too far out of the spirit to try crazy stuff.
