  • What's the best software analogy you've heard?

    - by Mantorok
    Hi Quite frequently I have to explain things to Project Managers who sometimes want to know a little bit more about something, and sometimes I try and come up with some analogy that best explains it. Now, I can't really kick this off with a good analagy because mine usually suck, but I would be interested in yours, or some you've heard that have been used to simplify explanations. One analogy that does come up often is when explaining Interfaces (i.e. .Net) to which I usually explain in terms of a vehicle has a driver interface, and all vehicles must implement that interface so that anyone who can drive a vehicle will be able to utilise it. Any more? Would like to hear some, both serious and humourous. Please close if a duplicate.

  • Radio buttons being reset in FF on cache-refresh

    - by Andrew Song
    (This is technically an addendum to an earlier StackOverflow question I had posted, but my original post asked a different question which doesn't really cover this topic -- I don't want to edit my older question as I feel this is different enough to merit its own page) While browsing my website in Firefox 3.5 (and only FF3.5), I come across a page with two radio buttons that have the following HTML code: <input id="check1" type="radio" value="True" name="check" checked="checked"/> <input id="check2" type="radio" value="False" name="check"/> This page renders as expected, with 'check1' checked and 'check2' unchecked. When I then go to refresh the page by pressing Control + R, the two radio buttons render, but they are both unchecked even though the raw HTML code is the same (as above). If I do a cache-miss refresh (via Control + F5 or Control + Shift + R), the page returns back to the way you'd expect it. This is not a problem in any other browser I've tried except FF3.5. What is causing these radio buttons to be reset on a normal refresh? How can I avoid this?

  • What is the technical skill degree of your co-workers?

    - by bonefisher
    For now it has been around 4 years that I work as developer. Most of my team mates, from their tech-skill, programming ability and code practices view, are somewhere between junior and senior. In all my previous jobs, there was a real geek who was brilliant at coding/analyzing/lead, but the others were just 'average' programmers. How would you rank your co-workers as good developers from rank 1 (best) - 5 (worst) ?

  • Which templating languages output HTML *as a tree of nodes*?

    - by alamar
    HTML is a tree of nodes, before all. It's not just a text. However, most templating engines handle their input and output as it was just a text; they don't care what happens around their tags, their {$foo}'s and <% bar() %>'s; also they don't care about what are they outputting. Sometimes they happen to produce a correct html, but that's just a coincidence; they didn't aim for that, all they wanted is to replace some funny marks in the text stream with their evaluation. There are a few templating engines which do treat their output as a set of nodes; XSLT and Haml come to mind. For some tasks, this has advantages: for example, you can automatically reformat (like, delete all empty text nodes; auto-indent; word-wrap). The result is guaranteed to be a correct xml/sgml unless you use a strict subset of operations that can break that. Also, such templating engine would automatically quote strings, differently in text nodes and in attributes, because it strictly knows whether you're writing an attribute or a text node. Moreover, it can conditionally remove a node from output because it knows where it does begin and end, which is useful, and do other non-trivial node operations. You might not like XSLT for its verbosiness or functionalness, but it's damn helps that your template is xmllint-able XML, and your output is a good sgml/xml. So the question is: Which template engines do you know that treat their output as a set of correct nodes, not just an unstructured text? I know XSLT, Haml and some obscure python-based one. Moar!

  • jQuery ajax form submit - how to ensure dynamically loaded form's action is used

    - by kenny99
    Hi, i'm having a problem with dynamically loaded forms - instead of using the action attribute of the newly loaded form, my jquery code is still using the action attribute of the first form loaded. I have the following code: //generic ajax form handler - calls next page load on success $('input.next:not(#eligibility)').live("click", function(){ $(".form_container form").validationEngine({ ajaxSubmit: true, ajaxSubmitFile: $(this).attr('action'), success : function() { var url = $('input.next').attr('rel'); ajaxFormStage(url); }, failure : function() { } }); }); But when the next form is loaded, the above code does not pick up the new action attribute. I have tried adding the above code to my callback on successful ajax load (shown below), but this doesn't make any difference. Can anyone help? Many thanks function ajaxFormStage(url) { var $data = $('#main_body #content'); $.validationEngine.closePrompt('body'); //close any validation messages $data.fadeOut('fast', function(){ $data.load(url, function(){ $data.animate({ opacity: 'show' }, 'fast'); '); //generic ajax form handler - calls next page load on success $('input.next:not(#eligibility)').live("click", function(){ $(".form_container form").validationEngine({ ajaxSubmit: true, ajaxSubmitFile: $(this).attr('action'), success : function() { var url = $('input.next').attr('rel'); ajaxFormStage(url); }, failure : function() { } }); }); }); });

  • Are certain open-source licenses more suitable than others for career growth?

    - by Francisco Garcia
    As a software engineer/programmer myself, I love the possibility to download the code and learn from it. However building software is what brings food to my table. I have doubts regarding the type of license I should use for my own personal projects or when picking up one project to learn from. There are already many questions about licenses on Stackoverflow, but I would like to make this one much more specific. If your main profession and way of living is building software: which type of license do you find more useful for you? And I mean, the license that can benefit you most as a professional because it gives you more freedom to reuse the experience you gain. GPL is a great license to build communities because it forces you to give back your work. However I like BSD licenses because of their extra freedom. I know that if the code I am exploring is BSD licensed, I might be able to expand not only my skills, but also my programmer toolbox. Whenever I am working for a company, I might recall that something similar was done in another project and I will be able to copy or imitate certain part of the code. I know that there are religious wars regarding GPL vs BSD and it is not my intention to start one. Probably many companies already take snipsets from GPL projects anyway. I just want to insist in the factor of professional enrichment. I do not intend to discriminate any license. I said I prefer BSD licenses but I also use Linux because the user base is bigger and also the market demand.

  • Problem: connecting to drupal on hostgator without pointed domain.

    - by Kirk
    I need to connect to drupal on a website that I'm programming on a hostgator account. The website that I'm working on currently receives a lot of traffic, and I would like to make sure that it is fully functional before I launch the new website. The old website was programmed with .asp which hostgator doesn't support, and the old webhost doesn't support drupal or .php which are integral to the new web design. Drupal 6 has been freshly installed on my website, but when I try to login, it redirects me to http://gator83.hostgator.com/?q=node&destination=node instead of the drupal control panel. Is it possible to work around this? Thank you in advance.

  • Killing Mysql processes staying in sleep command.

    - by Shino88
    Hey I am connecting a MYSQL database through hibernate and i seem to have processes that are not being killed after they are finished in the session. I have called flush and close on each session but when i check the server the last processes are still there with a sleep command. This is a new problem which i am having and was not the case yesterday. Is there any way i can ensure the killng of theses processes when i am done with a session. Below is an example of one of my classes. public JSONObject check() { //creates a new session needed to add elements to a database Session session = null; //holds the result of the check in the database JSONObject check = new JSONObject(); try{ //creates a new session needed to add elements to a database SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory(); session = sessionFactory.openSession(); if (justusername){ //query created to select a username from user table String hquery = "Select username from User user Where username = ? "; //query created Query query = session.createQuery(hquery); //sets the username of the query the values JSONObject contents query.setString(0, username); // executes query and adds username string variable String user = (String) query.uniqueResult(); //checks to see if result is found (null if not found) if (user == null) { //adds false to Jobject if not found check.put("indatabase", "false"); } else { check.put("indatabase", "true"); } //adds check to Jobject to say just to check username check.put("justusername", true); } else { //query created to select a username and password from user table String hquery = "Select username from User user Where username = :user and password = :pass "; Query query = session.createQuery(hquery); query.setString("user", username); query.setString("pass", password); String user = (String) query.uniqueResult(); if(user ==null) { check.put("indatabase", false); } else { check.put("indatabase", true); } check.put("justusername", false); } }catch(Exception e){ System.out.println(e.getMessage()); //logg.log(Level.WARNING, " Exception", e.getMessage()); }finally{ // Actual contact insertion will happen at this step session.flush(); session.close(); } //returns Jobject return check; }

  • Idiomatic PHP web page creation

    - by GreenMatt
    My PHP experience is rather limited. I've just inherited some stuff that looks odd to me, and I'd like to know if this is a standard way to do things. The page which shows up in the browser location (e.g. www.example.com/example_page) has something like: <? $title = "Page Title"; $meta = "Some metadata"; require("pageheader.inc"); ?> <!-- Content --> Then pageheader.inc has stuff like: <? @$title = ($title) ? $title : ""; @$meta = ($meta) ? $meta : ""; ?> <html> <head> <title><?=$title?></title </head> <!-- and so forth --> Maybe others find this style useful, but it confuses me. I suppose this could be a step toward a rudimentary content management system, but the way it works here I'd think it adds to the processing the server has to do without reducing the load on the web developer enough to make it worth the effort. So, is this a normal way to create pages with PHP? Or should I pull all this in favor of a better approach? Also, I know that "<?" (vs. "<?php" ) is undesirable; I'm just reproducing what is in the code.

    What is the best gallery to showcase web design you have came across? Plan to get various creative agencies to showcase their works on an advertisement platform so that new user will be able to see various portfolio. When it come to select a suitable album, I am indecisive if it too plain (Load and display) or too flashy (coverflow album), which album/gallery script do you recommend for our corporate theme? I would prefer background to be white.

  • Kernel thread exit in linux

    - by Raffo
    Hi guys, I'm here to ask you the difference between a process and a thread in linux. I know that a thread for linux is just a "task", which shares with the father process things that they need to have in common (the address space and other important informations). I also know that the two are creating calling the same function ('clone()'), but there's still something that I'm missing: what really happens when a thread exit? What function is called inside the linux kernel? I know that when a process exits calls the do_exit function, but here or somewhere else there should be a way to understand if it is just a thread exiting or a whole process. Can you explain me this thing or redirect to some textbook?? I tried 'Understanding the linux kernel' but I was not satisfied with it. I'm asking this thing because a need to add things to the task_struct struct, but I need to discriminate how to manage those informations for a process and its children. Thank you.

  • Are there any good resources on developing ASP.NET for Windows CE Internet Explorer?

    - by IronicMuffin
    I've been tasked with creating a web app to be consumed by a mobile device sporting Windows CE 5.0 (and some with Windows CE 4.2). I've found a host of things that seem to work fine in IE6 on my desktop, but fail when rendered in IE for Windows CE. IE6 is bad enough as it is...does it lose any more functionality on an embedded system? Are there quirks that a developer would need to know about? AJAX seems extremely unlikely. JavaScript seems quirky when linking to a .js file. Panels with scrollbars are finicky. Textboxes can't get focus. DefaultButtons on a form don't work. Any help or resources you can provide would be greatly appreciated.

  • What are the most likely reasons an application would fail on only one of my servers?

    - by Rising Star
    I have several servers to test new code on. I primarily push out asp.NET web applications. Last week, I had an issue where I installed a newly developed web application on three servers. The three servers all run in separate environments. The application worked fine on two of them, but consistently crashed on the third server with each web request. The problem was eventually traced to an in-house developed .dll file being out of date on the third server. I'm certain that this kind of thing happens all the time. However, there are numerous things that could go wrong to cause this kind of behavior. I spent quite a bit of time tracing this problem. I would like to make a list of things to be suspicious of next time this happens? What are the most likely reasons that a web application would crash on one of my servers while identical code runs fine on another server.

  • Using GET instead of POST to delete data behind authenticated pages

    - by Matt Spradley
    I know you should use POST whenever data will be modified on a public website. There are several reasons including the fact that search engines will follow all the links and modify the data. My question is do you think it is OK to use GET behind authenticated pages in something like an admin interface? One example would be a list of products with a delete link on each row. Since the only way to get to the page is if you are logged in, is there any harm in just using a link with the product ID in the query string?
