  • What programming languages do the top tier Universities teach?

    - by Simucal
    I'm constantly being inundated with articles and people talking about how most of today's Universities are nothing more than Java vocational schools churning out mediocre programmer after mediocre programmer. Our very own Joel Spolsky has his famous article, "The Perils of Java Schools." Similarly, Alan Kay, a famous Computer Scientist (and SO member) has said this in the past: "I fear — as far as I can tell — that most undergraduate degrees in computer science these days are basically Java vocational training." - Alan Kay (link) If the languages being taught by the schools are considered such a contributing factor to the quality of the school's program then I'm curious what languages do the "top-tier" computer science schools teach (MIT, Carnegie Mellon, Stanford, etc)? If the average school is performing so poorly due in large part the languages (or lack of) that they teach then what languages do the supposed "good" cs programs teach that differentiate them? If you can, provide the name of the school you attended, followed by a list of the languages they use throughout their coursework. Edit: Shog-9 asks why I don't get this information directly from the schools websites themselves. I would, but many schools websites don't discuss the languages they use in their class descriptions. Quite a few will say, "using high-level languages we will...", without elaborating on which languages they use. So, we should be able to get a pretty accurate list of languages taught at various well known institutions from the various SO members who have attended at them.

  • Providing dynamic data to webpage

    - by Marius
    Hi, I have a web page that displays dynamic data which changes every 2 seconds. Data is selected from various data sources including Oracle. Currently, the page reloads every 10 seconds and runs a PHP script which retrieves the data and displays the page. I have other pages that gives a different view on the same data. This means the same query is run again for them as well. If I have 4 of these pages with 10 concurrent users each, suddenly the data retrieval happens 40 times every 10 seconds, obviously not ideal. I have some ideas on how to improve this situation, but I thought I would ask from some ideas from other experts that might have come across a similar situation. I'm not bound to PHP, and my server is on a Linux platform. Regards Marius

  • Delphi/Pascal training in high school/college/university

    - by Bruce McGee
    Are Delphi/Pascal being taught in any high schools/colleges/universities, particularly in Canada and the US? I was surprised how many schools in the UK are teaching Delphi. Their largest exam board is even dropping PHP/C#/C in 2011 and encouraging Delphi. I also remember that CodeGear was going to provide development tool licenses to Russian schools a couple of years ago. I'd like to know if it's being taught closer to (my) home.

  • Help! I've learned jQuery... now I want to learn JavaScript

    - by Derek Adair
    I am a self-taught web developer/programmer. I started out about two years ago by learning how to make simple dynamic websites with HTML/CSS/PHP. Then I started dabbling with animation... Enter jQuery I've become quite proficient with jQuery over the last year and I've even started making my own plugins. I've spent most of my effort learning how to beautify websites with fancy effects and what not. Upon tackling my first full-blown application, I realized how under-developed my knowledge of JavaScript actually is. jQuery has allowed me to rely on its framework so heavily that I rarely use any interesting functions, techniques, or whatever that are 'native' to the JavaScript language. For example: I have a basic understanding of what a closure is... but I am unsure where this technique can actually benefit me. Although as I understand it, that's what my jQuery plugins do with (function ($){//plugin code here})(jQuery). I've seen many posts/blogs/whatever about memory leaks and circular references which is concerning. I'm frustrated because I can wrap my head around the basic concepts of what these are just by reading the articles, but I'm finding that the deeper I go the more I don't understand. The vocabulary alone is burdensome. Let alone how to actually use these techniques/functions/language features. I am trying to figure out what I don't know I'm looking to gather any advice, techniques, articles, books, videos, snippets, examples, potential pitfalls... really anything you have regarding application development with JavaScript/jQuery.

  • Write data to an xml file.

    - by Bobby
    My aim is to write an XML file with few tags whose values are the regional language. I'm using Python to do this and using IDLE(Pythong GUI) for programming. While I try to write the words in an xmls file it gives the following error. UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-4: ordinal not in range(128) For now, I'm not using any xml writer library instead I'm opening a file "test.xml" and writing the data into it. This error is encountered by the line: f.write("\t\" + data + "\"). If I replace the above write statement with print statement then it prints the data properly on Python Shell. I'm reading the data from an excel file which is not in the UTF8,16, or 32 encoding formats. Its in some other format. cp1252 is reading the data properly. Any help in getting this data writtent oan xml would be highly appreciated. Thanks in advance. Bob

  • Which Programming Language Should I Learn?

    - by Esteban Araya
    I've decided, for educational purposes, I want to learn a new language every 2 years or so. Which language should I learn first? Why? I'm proficient with C, C# and Java. Other than that, I really haven't done much with any other languages. Thanks! Edit: Thanks to all of those that recommended functional languages. Making the mental switch to a functional language seems hard. How did you overcome your instinct to keep doing things in a procedural manner?

  • Master's in Software Engineering vs. Master's in Computer Science: which degree is preferred by empl

    - by dbarker
    I've been building software professionally for 7 years and am considering a master's degree. I understand the difference between these two degrees as simply: MSCS is the theory while MSE is the practice. I'm equally interested in both and would be happy with either, although I'm curious how these degrees rank in the eyes of a potential employer. I could see two views that a hiring manager could possibly take: a MSCS is loftier and has an implied knowledge of Software Engineering an MSE is more practical and has an implied knowledge of Computer Science In my own experience I've seen both MSCS degree holders than cannot program at all while others are among the best programmers I've met, so of course actual ability will depend on the individual. My question is about the "on paper" value of these two degrees when seeking a job. All things considered, is one degree more hirable, higher-paying than the other?

  • Revision control for writing programming lessons

    - by Dietrich Epp
    I'd like to write a series programming lessons that guide programmers to build a certain kind of program. After each lesson, I'd like to provide sample code that implements what that lesson covered, and the next lesson would use that code as a starting point. Right now I'm using Git to keep track of the code from lesson to lesson. Each lesson has its own branch. lesson1: A--B--C \ lesson2: D--E--F \ lesson3: G--H--I However, suppose that now I want to make it easier on the Windows programmers using my lessons, so I add a Visual Studio project to lesson 1 and then merge it into lessons 2 and 3. lesson1: A--B--C--------------J \ \ lesson2: D--E--F--------K \ \ lesson3: G--H--I--L And then someone points out a bug in lesson 2 that causes crashes on certain systems. (This diagram is where I am right now, and I'm having doubts about continuing along this path.) lesson1: A--B--C--------------J \ \ lesson2: D--E--F--------K--M \ \ \ lesson3: G--H--I--L--N Here are the problems I imagine having: If I had many lessons, and I fix something in lesson 1, am I going to have to spend fifteen minutes or more just merging that one simple change? I know I'll probably have to test all of those lessons again, but I can put that off. When I make a bunch of changes to various lessons on one computer, how do I pull all of the branches at the same time? If I decide to publish these lessons, I'd like a way to tag all of the branches to correspond with what I publish. I figure I'll just need to tag each branch separately, but it would be nice if there were a better way. When I look at the history, I imagine becoming terribly confused about what I've done. Compare the above diagram to a hypothetical diagram below, where I use rebase instead of merge (and rebase has its own problems): lesson1: A--B--C--J \ lesson2: D2--E2--F2--M \ lesson3: G2--H2--I2 Do any of you have experience working with a project like this? Should I consider using a different VCS, such as Darcs? (Note: it would be a real pain to use centralized VCS, so don't suggest one of those unless the benefits are clear.) Should I consider writing plugins or extra tools for a VCS (such as a "meta tag" which tags several branches)?

  • Is speed reading good for technical / programming books?

    - by Ekkapop
    I will register as graduate student, and my friend has suggested I attend a speed reading class. (He is MBA student). I don't know whether it is good to attend this course or not, but at this moment almost of my textbook required time to think about its content. Has anyone applied speed reading with technical books? Is it good to attend this course?

  • BS in CS. Are specializations worth it?

    - by CheesePls
    I'm currently pursuing my BS in Computer Science and my school offers specializations based upon taking certain advanced electives. I was thinking about getting two of them since they are sort of on the way to my degree anyway. They are Software Engineering and Programming Languages and Compilers . Would these specializations actually be useful in finding a job? Would employers even care about them?

  • ItemFileWriteStore: how to change the data?

    - by jeff porter
    Hi, I'd like to change the data in my dojo.data.ItemFileWriteStore. Currently I have... var rawdataCacheItems = [{'cachereq':'14:52:03','name':'Test1','cacheID':'3','ver':'7'}]; var cacheInfo = new dojo.data.ItemFileWriteStore({ data: { identifier: 'cacheID', label: 'cacheID', items: rawdataCacheItems } }); I'd like to make a XHR request to get a new JSON string of the data to render. What I can't work out is how to change the data in the "items" held by ItemFileWriteStore. Can anyone point me in the correct direction? Thanks Jeff Porter

  • Should economics be taught to geeks?

    - by asksuperuser
    When I interview developers for jobs I'm really astonished by their lack of economics consciousness. It seems they think they'll be recruited just for technological fun. When you ask them for technical solutions they would just follow hypes from software editors without consideration for the economics part. I have rejected 80% of candidates just for that kind of reason. I don't know if other recruiters ask economics questions, but as for me that is one of the main criterias. That is why I prefer to enquiry by myself on technical questions because I just don't trust the geeks choice. So did you learn economics at school ? At mine yes and that did serve me.

  • Are open source projects considered community service?

    - by Gio Borje
    I'm currently a junior in high school and I've been slacking off on my community service to develop websites and do some personal projects in C#. Currently, I'm developing an web-based IM-Chat through node.js (the server-side Javascript). If I were to post this or other projects on Github or on Google Code, could this be considered community service?—to the programming community?

  • Programming mid-terms

    - by Dervin Thunk
    Hello. Unfortunately, (written) midterms are necessary in most university CS programs in the world. They tell us how well our students (and ourselves as teachers) are doing. Needless to say, designing midterms for a C Programming Language course is not easy. For instance, when we do program for real, we have a myriad of information at our disposal: websites, books, cheat sheets to "remember" the syntax and so on. My question is this: did you find any way, during your years at school or training, where you said: ok, this midterm evaluation of my programming skills is tough, but fair. For instance: I found "find 5 problems with this code"-type questions hard but interesting and telling. Are there any others? Thanks.

  • Is it worth it to learn an esoteric programming language?

    - by Thomas Owens
    Wikipedia: An esoteric programming language (sometimes shortened to esolang) is a programming language designed as a test of the boundaries of computer programming language design, as a proof of concept, or as a joke. There is usually no intention of the language being adopted for real-world programming. Such languages are often popular among hackers and hobbyists. This use of esoteric is meant to distinguish these languages from more popular programming languages. Some more popular languages may appear esoteric (in the usual sense of the word) to some, and though these could arguably be called "esoteric programming languages" too, this is not what is meant. I think it might be worth it, just to learn a new language and go through the process, although only if you don't have anything else to do (like a real project or learning a new real language). But what does the community think? Is there some value in these languages?

    Hi, My name is Gautam. I come from India. I am extremely passionate about Web Development.. I like to build web applications all the time.. Can I make this web application building a full time profession? I have just graduated from bachelors... Is there a Master of Computer Science in Web Development? Can I choose Masters in Web Development? Is it a bad choice? Is there a course very close to it Web Development that I can choose? Should I just keep Web Development as a part time thing to do?? Could you please let me know any good universities which offer this course/ close to this course for Spring 2010? Please advice on what I should do because my mind keeps throwing millions of questions on what I should do and my only hope is STACKOVERFLOW helps me as it always does to solve problems.. Looking forward for your reply.. Thanks in advance Regards, Gautam

  • Opinion on "loop invariants", and are these frequently used in the industry?

    - by Michael Aaron Safyan
    I was thinking back to my freshman year at college (five years ago) when I took an exam to place-out of intro-level computer science. There was a question about loop invariants, and I was wondering if loop invariants are really necessary in this case or if the question was simply a bad example... the question was to write an iterative definition for a factorial function, and then to prove that the function was correct. The code that I provided for the factorial function was as follows: public static int factorial(int x) { if ( x < 0 ){ throw new IllegalArgumentException("Parameter must be = 0"); }else if ( x == 0 ){ return 1; }else{ int result = 1; for ( int i = 1; i <= x; i++ ){ result*=i; } return result; } } My own proof of correctness was a proof by cases, and in each I asserted that it was correct by definition (x! is undefined for negative values, 0! is 1, and x! is 1*2*3...*x for a positive value of x). The professor wanted me to prove the loop using a loop invariant; however, my argument was that it was correct "by definition", because the definition of "x!" for a positive integer x is "the product of the integers from 1... x", and the for-loop in the else clause is simply a literal translation of this definition. Is a loop invariant really needed as a proof of correctness in this case? How complicated must a loop be before a loop invariant (and proper initialization and termination conditions) become necessary for a proof of correctness? Additionally, I was wondering... how often are such formal proofs used in the industry? I have found that about half of my courses are very theoretical and proof-heavy and about half are very implementation and coding-heavy, without any formal or theoretical material. How much do these overlap in practice? If you do use proofs in the industry, when do you apply them (always, only if it's complicated, rarely, never)?
