  • How long is a CS degree good for?

    - by Recursion
    I came upon a comment on another forum today and one user responding to another suggested that a CS degree is really only good for one through two years at the most, and after that its as if you never had it. Is this really true? is this what employers think? When I did CS I never learned anything new, we learned fundamentals like data structures, algorithms, time complexity, OS fundamentals, language characteristics. Most of this stuff has been around for the past 20 years or so.

  • Can JavaScript be overused?

    - by ledhed2222
    Hello stackoverflow, I'm a "long time reader first time poster", glad to start participating in this forum. My experience is with Java, Python, and several audio programming languages; I'm quite new to the big bad web technologies: HTML/CSS/JavaScript. I'm making two personal sites right now and am wondering if I'm relying on JavaScript too much. I'm making a site where all pages have a bit of markup in common--stuff like the nav bar and some sliced background images--so I thought I'd make a pageInit() function to insert the majority of the HTML for me. This way if I make a change later, I just change the script rather than all the pages. I figure if users are paranoid enough to have JavaScript turned off, I'll give them an alert or something. Is this bad practice? Can JavaScript be overused? Thanks in advance.

  • PHP: What's the best way to check equality of $_SERVER['HTTP_REFERER'] ?

    - by Hank
    I have a PHP script that checks the HTTP Referer. if ($_SERVER['HTTP_REFERER'] == 'http://www.example.com/') {...} However, this seems inherintly unsafe ... because what happens if the user goes to 'http://example.com/' or 'http://www.ExaMple.com' (both of which don't match the equality test). Question: what's a better equality test to ensure that the HTTP Referer is coming from 'example.com' ?

  • How can I be a Guru? Is it possible? [closed]

    - by Kev
    Before 1999, I heard about computer. But, I don't know what it look like. TV? Maybe! Before 2001, I only saw it in book. It looks like a TV. Before 2005, I touched it in reality. It still looks like a TV + Black Box. In 2005, I entered university. I had a cource about Mathematica.I loved programming since then. In 2006, I owned a computer. I was coding C every day. if...else..., for..., while..., switch... entered my life. Since 2007, I have learned Data Structures, Algorithms...Then, C#, Java, Python, HTML/CSS/JavaScript, F#... A lot of languages. I'm still learning new lang. Unfortunately, I only know syntax! I'm always a novice(??)! I know some guru start programming at age of 8 or 12. I admire these gurus who are compiler writers, language designers, architecture designers, Linux hackers... Is it possible to become a guru like me. If possible, how? what should I do now? Any advice? Thank you very much.

  • How do you get the pageYOffset of from the bottom of the window and not the top ( Javascript )?

    - by user782860
    I need to get the pageYOffset of the bottom of the viewable area, whether the user is zoomed in on the webpage or not, on Mobile Safari ( iPhone ). However pageYOffset returns the offset from the upper left corner of the window. Spec: "pageYOffset properties returns the pixels the current document has been scrolled from the upper left corner of the window" How do you get the page y offset from the bottom of the viewable area, (zoomed in or not) on the iPhone via Javascript?

  • One application instance for two domain name

    - by dervlap
    Hello, I have two web applications in ASP.NET which are quite the same (same business logic, same DAL, same DB scheme but different instance). The only thing that I need to change is the design (logo, color,...) and the text (global and local resource) to adress two separate business sector. We cannot "subdomain" the application because we need the two app "seems to be" independant. Is it a good idea to run only one instance for the 2 web applications. For example : I will have 2 hostnames : mycompagny.com and mycompagny2.com and I will put an HTTP Module which will set a string which will be propagated in my application like 'company' and 'company2'. I will instanciate the dal only once but the connection string will change depending on the string 'company' or 'company2'. Any pros and cons ? Any other alternatives ?

  • database design help for game / user levels / progress

    - by sprugman
    Sorry this got long and all prose-y. I'm creating my first truly gamified web app and could use some help thinking about how to structure the data. The Set-up Users need to accomplish tasks in each of several categories before they can move up a level. I've got my Users, Tasks, and Categories tables, and a UserTasks table which joins the three. ("User 3 has added Task 42 in Category 8. Now they've completed it.") That's all fine and working wonderfully. The Challenge I'm not sure of the best way to track the progress in the individual categories toward each level. The "business" rules are: You have to achieve a certain number of points in each category to move up. If you get the number of points needed in Cat 8, but still have other work to do to complete the level, any new Cat 8 points count toward your overall score, but don't "roll over" into the next level. The number of Categories is small (five currently) and unlikely to change often, but by no means absolutely fixed. The number of points needed to level-up will vary per level, probably by a formula, or perhaps a lookup table. So the challenge is to track each user's progress toward the next level in each category. I've thought of a few potential approaches: Possible Solutions Add a column to the users table for each category and reset them all to zero each time a user levels-up. Have a separate UserProgress table with a row for each category for each user and the number of points they have. (Basically a Many-to-Many version of #1.) Add a userLevel column to the UserTasks table and use that to derive their progress with some kind of SUM statement. Their current level will be a simple int in the User table. Pros & Cons (1) seems like by far the most straightforward, but it's also the least flexible. Perhaps I could use a naming convention based on the category ids to help overcome some of that. (With code like "select cats; for each cat, get the value from Users.progress_{cat.id}.") It's also the one where I lose the most data -- I won't know which points counted toward leveling up. I don't have a need in mind for that, so maybe I don't care about that. (2) seems complicated: every time I add or subtract a user or a category, I have to maintain the other table. I foresee synchronization challenges. (3) Is somewhere in between -- cleaner than #2, but less intuitive than #1. In order to find out where a user is, I'd have mildly complex SQL like: SELECT categoryId, SUM(points) from UserTasks WHERE userId={user.id} & countsTowardLevel={user.level} groupBy categoryId Hmm... that doesn't seem so bad. I think I'm talking myself into #3 here, but would love any input, advice or other ideas.

  • Include a repetitive chunk of html with PHP?

    - by user146780
    I basically have a div on my Web Site that always has the same stuff. However, this div is not present on all pages which is why I won't use the dynamic web template. I was wondering if it was possible for PHP to get the code from a document on the server and put in into the div? Ex: div id="section... then my text file contains (p) hello (p) basically I want PHP to put it into the div when the user sees it. If theres a smarter way of acheiving this I'd be open to it aswell. Thanks
