  • How do I change careers to become a programmer with little money

    - by bgc83
    I'm currently a network engineer, but find myself wanting to get into the world of development. I took a little bit of Java in college, am 27 years old and have been network engineering for 4 years now. I have a mortgage and student loans so going back to school would be difficult. I'm willing to put in however much hardwork is needed around my full time job to learn, but part of me feels I may need actuall schooling to get down some of the advanced concepts. Just looking for a little advice and direction. I have purchased a bunch of the Head First programming books and have begun reading through some of them as I figure out my way into this transition.

  • Intermittent issue - IIS offering to donwload ASPX file instead of executing

    - by Nataliya
    We're getting an intermittent problem with the homepage of our site when IIS will suddenly start offering to download the ASPX file instead of executing it. It happens about once a month, on a random basis. If I open the file in Notepad and re-save it (without making a single change to the code), IIS starts executing the script as normal and doesn't offer the download any more. I can't get my head round this, considering that we can't reproduce the problem. Also, I can't really play with it and test anything when the problem occurs as this is the homepage of the site and needs fixing asap. Any ideas what could be causing this? Files are written to the server over Filezilla FTP. Looks like the homepage is the only page affected. Server is Windows Server 2003, IIS 6.0 with all the latest patches (we actually run two of them, load balanced, and the problem can occur on either server on a random basis). Can't see anything in the Event logs or IIS log.

  • Artificial Intelligence in online game using Google App Engine

    - by Hortinstein
    I am currently in the planning stages of a game for google app engine, but cannot wrap my head around how I am going to handle AI. I intend to have persistant NPCs that will move about the map, but short of writing a program that generates the same XML requests I use to control player actions, than run it on another server I am stuck on how to do it. I have looked at the Task Queue feature, but due to long running processes not being an option on the App engine, I am a little stuck. I intend to run multiple server instances with 200+ persistant NPC entities that I will need to update. Most action is slowly roaming around based on player movements/concentrations, and attacking close range players...(you can probably guess the type of game im developing)

  • JavaScript onload/onreadystatechange not firing when dynamically adding a script tag to the page.

    - by spoon16
    I am developing a bookmarklet that requires a specific version of jQuery be loaded on the page. When I have to dynamically insert a jQuery script tag to meet the requirments of the bookmarklet I want to wait for the onload or onreadystatechange event on the script tag before executing any function that requires jQuery. For some reason the onload and/or onreadystatechange events do not fire. Any ideas on what I am doing wrong here? var tag = document.createElement("script"); tag.type = "text/javascript"; tag.src = "http://ajax.microsoft.com/ajax/jquery/jquery-" + version + ".min.js"; tag.onload = tag.onreadystatechange = function () { __log("info", "test"); __log("info", this.readyState); }; document.getElementsByTagName('head')[0].appendChild(tag); The FULL code: http://gist.github.com/405215

  • IOC - Should util classes with static helper methods be wired up with IOC?

    - by Greg
    Hi, Just trying to still get my head around IOC principles. Q1: Static Methods - Should util classes with static helper methods be wired up with IOC? For example if I have a HttpUtils class with a number of static methods, should I be trying to pass it to other business logic classes via IOC? Follow on questions for this might be: Q2: Singletons - What about things like logging where you may typically get access to it via a Logger.getInstance() type call. Would you normally leave this as is, and NOT use IOC for injecting the logger into business classes that need it? Q3: Static Classes - I haven't really used this concept, but are there any guidelines for how you'd typically handle this if you were moving to an IOC based approach. Thanks in advance.

  • Overriding Home button for a Car Home replacement app

    - by BigFwoosh
    I have been working on a replacement for the stock Car Home app for a bit, and I am completely stumped on how to override the Home button so that my app will be brought back to the foreground whenever the phone is docked. This is the way that Car Home works, so there must be a way. It seems that BroadcastReceivers won't work, because the intent that is broadcast whenever the Home button is pressed will still cause the default homescreen app to launch; I cannot prevent it. I can override the Home button from within my app, but that does me no good since this needs to work when the user is outside my app. Car Home also does not do anything weird like set itself as the default homescreen app while it's running (I checked the logcat to make sure). I've been really beating my head against the wall on this. Does anyone have any ideas, or can you at least point me in the right direction?

  • Limit JavaScript and CSS files on ASP.NET MVC 2 Master Page based on Model and View content

    - by Zack Peterson
    I want to include certain .js and .css files only on pages that need them. For example, my EditorTemplate DateTime.ascx needs files anytimec.js and anytimec.css. That template is applied whenever I use either the EditorFor or EditorForModel helper methods in a view for a model with a DateTime type value. I've put this condition into the <head> section of my master page. It checks for a DateTime type property in the ModelMetadata. <% if (this.ViewData.ModelMetadata.Properties.Any(p => p.ModelType == typeof(DateTime))) { %> <link href="../../Content/anytimec.css" rel="stylesheet" type="text/css" /> <script src="../../Scripts/anytimec.js" type="text/javascript"></script> <% } %> This has two problems: Fails if I have nested child models of type DateTime Unnecessarily triggered by views without EditorFor or EditorForModel methods (example: DisplayForModel) How can I improve this technique?

  • openssl error wehn compiling Ruby from source

    - by Florian Salihovic
    Prelude: I don't want to use rvm. I installed ruby 2 with the following configuration on Mac OS X 10.8.5 ./configure --prefix=/usr/local \ --enable-pthread \ --with-readline-dir=/usr/local \ --enable-shared It is installed, version is printed correctly ... Now, when invoking gem install jekyll I get the following error: ERROR: Loading command: install (LoadError) cannot load such file -- openssl ERROR: While executing gem ... (NoMethodError) undefined method `invoke_with_build_args' for nil:NilClass I installed openssl into /usr/local but i'm really banging my head against the wall on how installing gems. It can't be that big of a deal right?

  • My object becomes NSCFArray when running on iPhone

    - by cagreen
    I'm really scratching my head on this one: I have an object (MyObject) which I instantiate, and this object has an NSArray member variable. The following simple code working in the sim: MyObject *myObj = [[MyObject alloc] init]; NSArray *arr = [myObj myMemberArray]; When I hover over myObj in XCode the tooltip reads "MyObject". Good! But when I debug it on the device (OS 3.1.3) I get: "[NSCFArray myMemberArray]: unrecognized selector sent to instance ... " When I hover over myObj, sure enough it reads "NSCFArray". Can anyone give me some pointers on where to go next with this? Thanks.

  • ViewController vs. View

    - by James
    Trying to wrap my head around the apple design scheme. I have a UIViewController and the corresponding XIB file that has my main screen in my application. I want to have a button on this XIB that displays another "form" (this is my disconnect) in the foreground where the user selects from a myriad of choices, then it hides that "form" and goes back to the first one. I'm completely lost here. Initially I thought I'd just add another view and set the self.view of my controller to the new view, add another IBAction and call it a day, but I can't seem to make that work. For sake of argument, say I want to "gray out" the current form, have a modal type window that takes up roughly 60% of the screen and requires you select an option, then it hides itself and we go back to normal. What is the standard approach here? Thanks

  • Tutorials/Books on using Mono to develop RESTful webservices?

    - by max
    Hi, anyone out there got any pointers to good links/tutorials/books on developing webservices with Mono? In more detail, I am interested in using Mono from project start on a Linux host developing in C# using Visual Studio for development, ideally with remote debugging if that is realistic developing web-services in MONO accessible in a RESTful manner, returning JSON hiding the services processes behind an Apache access the services either via javascript/AJAX or from a thin script layer written in PHP scalability is important for me unit-testing of webservices Any recommendations for material I could sift through to get a good head-start? I might add that I'm C#/.NET savvy, but not in the context of web development. I've been using it since it came out, but mainly for internal server-client applications where the clients were Windows desktop apps and the communication layer was remoting or, sometimes, more low-level socket-based. Thanks, max

  • jquery, moving the current item to the top

    - by azz0r
    Hello, The problem I'm having is that if the fourth item has a long description, it cuts off as it goes below #features. What I was hoping is someone would have a suggestion on how to make the current item selected to move to the top? Code below: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <script type="text/javascript" src="/library/jquery/1.4.js"></script> <script> Model.FeatureBar = { current:0, items:{}, init: function init(options){ var me = this; me.triggers = [] me.slides = [] this.container = jQuery('#features'); jQuery('.feature').each(function(i){ me.triggers[i] = {url: jQuery(this).children('.feature-title a').href, title: jQuery(this).children('.feature-title'),description:jQuery(this).children('.feature-description')} me.slides[i] = {image: jQuery(this).children('.feature-image')} }); for(var i in this.slides){ this.slides[i].image.hide(); this.triggers[i].description.hide(); } Model.FeatureBar.goToItem(0); setInterval(function(){Model.FeatureBar.next()},5000); }, next: function next(){ var i = (this.current+1 < this.triggers.length) ? this.current+1 : 0; this.goToItem(i); }, previous: function previous(){ var i = (this.current-1 > 1) ? this.current-1 : this.triggers.length; this.goToItem(i); }, goToItem: function goToItem(i) { if (!this.slides[i]) { throw 'Slide out of range'; } this.triggers[this.current].description.slideUp(); this.triggers[i].description.slideDown(); this.slides[this.current].image.hide(); this.slides[i].image.show(); this.current = i; }, } </script> </head> <body> <div id="features"> <div class="feature current"> <div style="display: none;" class="feature-image"> <a href="google.com"><img src="/design/images/four-oh-four.png"></a> </div> <h2 class="feature-title"><a href="google.com">Item 3</a></h2> <p style="display: none;" class="feature-description"><a href="google.com">Item 3 description</a></p> </div> <div class="feature"> <div class="movie-cover"> <a href="/movie/movie"><img src="/image1" alt="" title=""></a> </div> <div style="display: block;" class="feature-image"> <a href="/rudeboiz-14-arse-splitters/movie"><img src="/images/Featured/rude.png"></a> </div> <h2 class="feature-title"><a href="/rude/movie">Item 2</a></h2> <p style="display: block;" class="feature-description"><a href="/rude/movie">Item 2 description</a></p> </div> <div class="feature"> <div style="display: none;" class="feature-image"> <a href="/pissed-up-brits/movie"><img src="/design/images/four-oh-four.png"></a> </div> <h2 class="feature-title"><a href="/pis/movie">Item 1</a></h2> <p style="display: none;" class="feature-description"><a href="/pis/movie">Item one description</a></p> </div> <div class="feature"> <div style="display: none;" class="feature-image"> <a href="what.com"><img src="/images/Featured/indie.png"></a> </div> <h2 class="feature-title"><a href="what.com">Item 4</a></h2> <p style="display: none;" class="feature-description"><a href="what.com">Item 4 description</a></p> </div> </div> </body> </html>

  • Design Code Outside of an IDE (C#)?

    - by ryanzec
    Does anyone design code outside of an IDE? I think that code design is great and all but the only place I find myself actually design code (besides in my head) is in the IDE itself. I generally think about it a little before hand but when I go to type it out, it is always in the IDE; no UML or anything like that. Now I think having UML of your code is really good because you are able to see a lot more of the code on one screen however the issue I have is that once I type it in UML, I then have to type the actual code and that is just a big duplicate for me. For those who work with C# and design code outside of Visual Studio (or at least outside Visual Studio's text editor), what tools do you use? Do those tools allow you to convert your design to actual skeleton code? It is also possible to convert code to the design (when you update the code and need an updated UML diagram or whatnot)?

  • Why does this crash?

    - by Adam Driscoll
    I've been banging my head...I can't pretend to be a C++ guy... TCHAR * pszUserName = userName.GetBuffer(); SID sid; SecureZeroMemory(&sid, sizeof(sid)); SID_NAME_USE sidNameUse; DWORD cbSid = sizeof(sid); pLog->Log(_T("Getting the SID for user [%s]"), 1, userName); if (!LookupAccountName(NULL, (LPSTR)pszUserName, &sid, &cbSid, NULL, 0, &sidNameUse)) { pLog->Log(_T("Failed to look up user SID. Error code: %d"),1, GetLastError()); return _T(""); } pLog->Log(_T("Converting binary SID to string SID")); The message 'Getting the SID for user [x] is written' but then the app crashes. I'm assuming is was the LookupAccountName call. EDIT: Whoops userName is a MFC CString

  • Switching/Linking to another external stylesheet in a .js file using Ruby on Rails

    - by Jake
    Im learning JQuery from a Sitepoint Book but Im trying to apply all the lessons to a Rails App. In one lesson, we are taught how to switch to a different stylesheet if the browser window is resized beyond a certain point. Here's the javascript code: if ($('body').width() > 900) { $('<link rel="stylesheet" href="wide.css" type="text/css" />') .appendTo('head'); } else { $('link[href=wide.css]').remove(); } Rails doesn't seem to want to link to the new stylesheet using 'link rel'. I've tried using the Rails helper: <%= stylesheet_link_tag 'base', :media => 'screen' %> but that doesn't work in a .js file. How do I link to an external stylesheet in a .js file using Ruby? Can I use Ruby on Rails code in a .js file? Thanks.

  • tool for adding parentheses to equations?

    - by jedierikb
    Is there an online tool for adding parentheses to simple math equations? For example, a + b * c into a + (b * c) Those who paid more attention in math class might be able to tackle order of operations for huge equations in their head, but I could often use some help (and verification of my thinking). I often encounter other people's libraries having equations and functions I need for my code, and this would be kind of helpful for debugging and understanding. I was hoping Wolfram Alpha would do this, but the output is not easy to plug back into most programming languages e.g. a + (bc)

  • What's happened to my directory on GitHub?

    I added a new subdir within my git respository: git add feeds Then commited this and pushed it up to GitHub but it seems as though I've commited a symlink / shortcut but not the actual directory and files within. See here: http://github.com/G4EGK/RSS-Reader Any idea what 'feeds' is? I'd like to remove that and correctly add my files. I tried the following but git status said nothing had changed: git rm feeds git add feeds/\*.php To remove feeds do I run the following? git filter-branch --tree-filter 'rm -f feeds' HEAD

  • sql server datetime

    - by cvista
    hey i have the following query: select * from table where table.DateUpdated >='2010-05-03 08:31:13:000' all the rows in the table being queried have the following DateUpdated: 2010-05-03 08:04:50.000 it returns all of the rows in the table - even though it should return none. I am pretty sure this is because of some crappy date/time regional thing. if i swap the date to be select * from table where table.DateUpdated >='2010-03-05 08:31:13:000' then it does as it should. How can i force everything to be using the same settings? this is doing my head in :) This is sql generated by NHIbernate from my WCF service if that matters. w://

  • How to send argument securely using Process class?

    - by Sebastian
    Hello, I'm using System.Diagnostics.Process to execute an svn command from a windows console application. This is the configuration of the process: svn.StartInfo.FileName = svnPath; svn.StartInfo.Arguments = string.Format("copy {0}/trunk/ {0}/tags/{1} -r head -q --username {3} --password {4} -m \"{2}\"", basePathToRepo, tagName, message, svnUserName, svnPassword); svn.StartInfo.UseShellExecute = false; svn.Start(); svn.WaitForExit(); My problem is that those arguments, which include the svn credentials, are sent (I suppose) in an unsecure way. Is there a way to send these arguments in a secure way using the Process class? Thanks!

  • Update User Info with restful_authentication plugin in Rails?

    - by benoror
    Hi people, I want to give the users the ability to change their account info with restful_authentication plugin in rails. I added this two methods to my users controller: def edit @user = User.find(params[:id]) end def update @user = User.find(params[:id]) # Only update password when necessary params[:user].delete(:password) if pàrams[:user][:password].blank? respond_to do |format| if @user.update_attributes(params[:user]) flash[:notice] = 'User was successfully updated.' format.html { redirect_to(@user) } format.xml { head :ok } else format.html { render :action => "edit" } format.xml { render :xml => @user.errors, :status => :unprocessable_entity } end end end Also, I copied new.html.erb to edit.html.erb. Considering that resources are already defined in routes.rb I was expecting it to work easily, bute somehow when I click the save button it calls the create method, instead of update, using a POST http request. Inmediatly after that it autocatically log out form the session. Any ideas?

  • Is there any better way for creating a dynamic HTML table without using any javascript library like

Just javascript. No Jquery library etc. I was confused that in the middle of the project why he asking for some stupid exercise like this. What ever i wrote the following code and mailed him and after 15 mins i got a mail from him. " I was expecting much better code from a guy like you. Anyways good job monkey.(And with a picture of monkey as attachment.) thats was the mail. Line by line. I want to reply him but before that i want to know about the quality of my code. Is this really shitty...!!! Or he was just making fun of mine. I dont think that code is really shitty. Still correct me if you can.Code is working perfectly fine.

  • comparing two cursors in oracle instead of using MINUS

    - by Omnipresent
    The following query takes more than 3 minutes to run because tables contain massive amounts of data: SELECT RTRIM(LTRIM(A.HEAD)), A.EFFECTIVE_DATE, FROM TABLE_1 A WHERE A.TYPE_OF_ACTION='6' AND A.EFFECTIVE_DATE >= ADD_MONTHS(SYSDATE,-15) MINUS SELECT RTRIM(LTRIM(B.head)), B.EFFECTIVE_DATE, FROM TABLE_2 B In our system a query gets killed if it is running for more than 8 seconds. Is there a way to run the queries individually ..put them in cursors..compare and then get the results? that way each query will be ran individually rather than as one massive query which takes 3 minutes. How would two cursors be compared to mimic the MINUS?

  • Javascript (JQuery) keyboard hijack problem

    - by user266564
    I'm making a typing tutor program using javascript. Everything is going well except that if activates browser hotkeys which disrupts the functionality of the program. When I press the single quote in Firefox it triggers "Quick find (links only)" short cut and in all browsers when I press space the page scrolls down a page. Everything is working fine outside of this. Here's the code in the head: <script type="text/javascript"> $(document).ready(function() { executeType(); }); </script> And the code I am using to capture the keyboard (simplified, but tested): function executeType() { $(document).keydown(function(event) { alert(event.keyCode); }); }

  • Monitor database table for external changes from within Rails application

    - by jhwist
    I'm integrating some non-rails-model tables in my Rails application. Everything works out very nicely, the way I set up the model is: class Change < ActiveRecord::Base establish_connection(ActiveRecord::Base.configurations["otherdb_#{RAILS_ENV}"]) set_table_name "change" end This way I can use the Change model for all existing records with find etc. Now I'd like to run some sort of notification, when a record is added to the table. Since the model never gets created via Change.new and Change.save using ActiveRecord::Observer is not an option. Is there any way I can get some of my Rails code to be executed, whenever a new record is added? I looked at delayed_job but can't quite get my head around, how to set that up. I imagine it evolves around a cron-job, that selects all rows that where created since the job last ran and then calls the respective Rails code for each row.

  • When to use or not use symbols in PHP

    - by brett
    I'm reading a PHP book where the author says that symbols should be avoided except when it's valid to use them. Very informative stuff, if he could only elaborate or give code examples but he doesn't. Can someone from the experienced PHP bunch give me an example of what these symbols are, and when it makes sense to use them or not. I'm looking for a code example that I can wrap my head around since I don't quite get it in plain English. Code is more plain English to me.
