• What are good resources to learn Coldfusion for a job application...

  - by NoMoreZealots

  The job title is "ColdFusion Developer." I have bit's HTML and Javascripting experience, but mostly have worked in the "harder" languages such as C and C++ with occational flurries of assembly. I'm currently employeed, but in the current job climate I figure it can't hurt to be looking around and applying for other positions. Plus according to the friend who sent me the job posting, it is suppose to pay "very well." They left my office to work for this company themself so I figure it's a reasonable evaluation of the company. I don't know if there are any free tools that I could use to get my feet wet and bone up for an interview, or what sort of literature is decent for the ColdFusion. Plus any ideas on how to tune a resume for it would also be helpful.

• saving a records containing a member of type string to a file (Delphi, Windows)

  - by wonderer

  I have a record that looks similar to: type TNote = record Title : string; Note : string; Index : integer; end; Simple. The reason I chose to set the variables as string (as opposed to an array of chars) is that I have no idea how long those strings are going to be. They can be 1 char long, 200 or 2000. Of course when I try to save the record to a type file (file of...) the compiler complains that I have to give a size to string. Is there a way to overcome this? or a way to save those records to an untyped file and still maintain a sort of searchable way? Please do not point me to possible solutions, if you know the solution please post code. Thank you

• jquery draggable into sortable only works after sorting

  - by Dao

  Hi, I'm experiencing problems with a simple combination of a Draggable and Sortable: initially, the dragging does not work and I do not get a receive callback. Only after I have done a sort (i.e. change the position of things in #workarea), can I drag new things into it. Somehow it seems as if the sortable needs to be 'initialized' before it accepts draggables. My code, in a simplified version: $(".element_draggable").draggable({ zIndex: 2, helper: 'clone', connectToSortable: '#workarea'}); $("#workarea").sortable({ receive: function() {alert('received');} }); Does anyone have an idea on what I could be doing wrong here?

• "Invalid Procedure Call or Argument", but only in a compiled or P-Code EXE

  - by Rob Perkins

  I have a VB6 program which I've been maintaining for ten years. There is a subroutine in the program called "Prepare Copy", which looks like this: Public Sub PrepareCopy() Set CopiedShapes = New Collection End Sub Where CopiedShapes is dimmed out as a VB6 Collection. That code is now kicking out a Runtime Error 5 -- Invalid Procedure Call or Argument. It appears from the interstitial debugging code that the error arises between the Public Sub PrepareCopy() and the Set CopiedShapes = New Collection lines. That's right. The VB6 error is happening between two lines of my code. I can think of no other explanation for this. It's behaving this way on my development machine and two client computers. It is only happening in runtime code, and does not appear to make a difference whether I compile it or use P-Code What I'm asking for here is speculation as to what causes this sort of thing to happen.

• Making Eclipse behave like Visual Studio

  - by FlySwat

  I'm doing some Android dev, and I much prefer Visual Studio, but I'll have to use Eclipse for this. Has anyone made a tool that switches Eclipse to look and behave more like visual studio? I mainly can't stand its clippyesqe suggestions on how I should program (Yes, I know I have not yet used that private field! Thanks Eclipse!), or its incredibly lousy intellisense. For example, in eclipse, if I don't type "this" first, its intellisense won't realize I want to look for locally scoped members. Also, the TAB to complete VS convention is drilled into my head, and Eclipse is ENTER to complete, I could switch everything by hand but that would take hours, and I was hoping someone had some sort of theme or something that has already done it :)

• Comparing two ISO8601 dates strings in PHP

  - by oompahloompah

  I need to compare (actually rank/sort) dates in a PHP script. The dates are ISO-8601 Date format i.e. YYYY-MM-DD I wrote a comparison function which splits the dates and compares by year/month/day. However, it seems this may be overkill and I could just as easily done a simple string comparison like: if ($date1 < $date2) // do something elseif( $date1 > $date2) //do something else else //do yet another thing Is my assumption about (ISO-8601) Date string comparison correct - i.e. can I get rid of my function (to save a few clock cycles on the server), or is it safer to explicity do the comparison in a custom function?

• Adding Colours (Colors) Together like Paint (Blue + Yellow = Green, etc)

  - by glenstorey

  I'm making an iOS game using cocos2d libraries. Lets say you have two objects that have two separate colours - defined in RGB as Blue: 0,0,255 Yellow: 255,255,0 I want to add blue and yellow to make green. To over complicate things, let's say that the Blue object is bigger than the Yellow object (for the sake of argument let's say that the ratio is 2:1), I'm adding twice as much blue as yellow - how to I calculate this new (light green) colour correctly. I understand LAB * Color Space is useful for this sort of 'natural colour' kind of thing, but I'm not sure how to use it - especially in the context of a cocos2d object which (AFAIK) is limited to using RGB in its colour schemes. I'd really appreciate practical help on how to implement this. Thanks heaps!

• Is a "Confirm Email" input good practice when user changes email address?

  - by dibson

  My organization has a form to allow users to update their email address with us. It's suggested that we have two input boxes for email: the second as an email confirmation. I always copy/paste my email address when faced with the confirmation. I'm assuming most of our users are not so savvy. Regardless, is this considered a good practice? I can't stand it personally, but I also realize it probably isn't meant for me. If someone screws up their email, they can't login, and they must call to sort things out.

• Oracle (Old?) Joins - A tool/script for conversion?

  - by Grasper

  I have been porting oracle selects, and I have been running across a lot of queries like so: SELECT e.last_name, d.department_name FROM employees e, departments d WHERE e.department_id(+) = d.department_id; ...and: SELECT last_name, d.department_id FROM employees e, departments d WHERE e.department_id = d.department_id(+); Are there any guides/tutorials for converting all of the variants of the (+) syntax? What is that syntax even called (so I can scour google)? Even better.. Is there a tool/script that will do this conversion for me (Preferred Free)? An optimizer of some sort? I have around 500 of these queries to port.. When was this standard phased out? Any info is appreciated.

• Html dynamically repeated border-image

  - by Clox

  I have a table which border I want to have a sort of zig-zag shape. I want the table to have an automatic size; resizing depending on how big the browser is. But rrathe than just having an image that gets stretched I want a seamless image that gets repeat instead. I found out this can be done with CSS3's Border-image but by looking and Browser Statistics I can see than only about half of all the viewers will be able to see it since no version of IE does yet support it. So I'm looking for an alternate method. What would be the best way of doing it? Thanks in advance!

• KMeans clustering for more than 5 million vectors

  - by Wajih

  I have hit a real problem. I need to do some Kmeans clustering for 5 million vectors, each containing about 32 cols. I tried out Mahout which requires linux and I am on windows, I am restrained from using a Linux OS and any sort of simulator. Can anyone suggest a KMeans clustering algorithm that is scalable upto 5M vectors and can converge quickly? I have tested a few but they wont scale. Which means they are slow and take forever to complete. Thanks

• Effecient data structure design

  - by Sway

  Hi there, I need to match a series of user inputed words against a large dictionary of words (to ensure the entered value exists). So if the user entered: "orange" it should match an entry "orange' in the dictionary. Now the catch is that the user can also enter a wildcard or series of wildcard characters like say "or__ge" which would also match "orange" The key requirements are: * this should be as fast as possible. * use the smallest amount of memory to achieve it. If the size of the word list was small I could use a string containing all the words and use regular expressions. however given that the word list could contain potentially hundreds of thousands of enteries I'm assuming this wouldn't work. So is some sort of 'tree' be the way to go for this...? Any thoughts or suggestions on this would be totally appreciated! Thanks in advance, Matt

• Content pulled in via jQuery AJAX is not associating with previous functions

  - by Jarsen

  I'm using the jquery .load() function to pull in data to populate a div with. The content I'm pulling in has CSS selectors that should match up with jQuery click functions I've written. However, when I load in the data, although the correct CSS selectors are there, when I click on areas that should invoke a response from jQuery, nothing happens. Do I need to do some sort of reload? Here's the code I've got for the jQuery AJAX: $(document).ready(function() { // AJAX functionality for drupal nodes $(".ajax_node").click(function() { var ajax_src = $(this).attr("href"); // we're gonna load the href // empty target div and load in content // the space in the string before the #id is necessary $("#ajax_area").empty().load(ajax_src + " #ajax_wrapper"); return false; // stops the link from following through }); // General AJAX fucntionality $(".ajax").click(function() { var ajax_src = $(this).attr("href"); $("#ajax_area").empty().load(ajax_src); return false; }); });

• Hbase schema design -- to make sorting easy?

  - by chen

  I have 1M words in my dictionary. Whenever a user issue a query on my website, I will see if the query contains the words in my dictionary and increment the counter corresponding to them individually. Here is the example, say if a user type in "Obama is a president" and "Obama" and "president" are in my dictionary, then I should increment the counter by 1 for "Obama" and "president". And from time to time, I want to see the top 100 words (most queried words). If I use Hbase to store the counter, what schema should I use? -- I have not come up an efficient one yet. If I use word in my dictionary as row key, and "counter" as column key, then updating counter(increment) is very efficient. But it's very hard to sort and return the top 100. Anyone can give a good advice? Thanks.

• How do I trigger a closing animation for a WPF ContextMenu?

  - by Ashley Davis

  Does anyone know if it is possible to trigger an animation when a WPF ContextMenu closes? I have code that triggers an animation when the ContextMenu is opened. The animation makes the context menu fade into view. I also want an animation when the ContextMenu is closed that makes it fade out. The code that starts the opened fade-in animation looks something like this: var animation = new DoubleAnimation(); animation.From = 0; animation.To = 1; animation.Duration = TimeSpan.FromSeconds(0.2); animation.Freeze(); menu.BeginAnimation(ContextMenu.OpacityProperty, animation); The fade-in animation also runs on sub-menu items. Note that I also want to run other animations besides fade in and fade out. Eg I want the context menu to scale up from nothing so that it sort of 'bounces' into view.

• Secure web service works in Firefox but not in IE7

  - by tridium

  I am trying to call a C# web service from one data center to another. I am able to load the web service properly in Firefox 3.6.3 but it does not load at all in Internet Explorer 7. When I try to install the application which relies on this web service, it can't find the web service at all, just like IE7. Is there any setting or configuration that would allow one browser to load it properly but not the other? I suspect that there's no firewall or that sort of problem because the web service loads for at least one browser.

• Given a number of rectangles that can be rotated, find an enclosing rectangle of minimum area

  - by efficiencyIsBliss

  So, I'm trying to implement an algorithm that takes in a number of rectangles as input and tries to pack them into a rectangle of minimum area. The rectangles can all be rotated by 90 degrees. I realize that this is similar to the bin packing problem, but I am unable to find a good algorithm that accounts for the rotation. I found a paper that discusses this at length here and while I understand the article itself, I was hoping to find something simpler. Any suggestions? -Edit- I think I misstated the problem earlier. We are given a number of rectangles, such that each can be rotated by 90 degrees. We need to find a rectangle that fits all the given rectangles such that no two rectangles overlap, while minimizing the area of the enclosing rectangle. The problem I face here is that we are asked to find the minimum, as opposed to being given an enclosing rectangle and checking if the given rectangles fit or something of that sort.

• Business Objects Web Intelligence-style reporting in a Winform app. Is this possible?

  - by George

  I have a WinForm app that displays results in a Gridview control. If a user right mouse clicks on a row, he can then, from a popup menu, select a command to perform on the row much like windows File Explorer. But now I want to be able to give the user the ability to construct a filter so that he can control which rows are displayed in the grid w/o effecting the functionality of the application. I would also like the user to be able to select the columns/fields that he sees in the grid. For the basis of this question, let's assume that the data displayed in grid comes from a single table. business Objects' Web Intelligence and Desktop Intelligence applications give me very flexible and powerful reporting capabilities, but I want to integrate this capability into my WinForm application. Does Business Objects, or maybe Crystal Reports provide this sort of functionality? I can construct my own query builder but I'd rather not reinvent sliced bread.

• LINQ group one type of item

  - by Nelson

  I have a List that has various derived classes. I may have something like this: List<BaseClass> list = new List<BaseClass>() { new Class1(), new Class2(1), new Class3(), new Class2(2), new Class4() }; I am trying to use LINQ to semi-sort the list so that the natural order is maintained EXCEPT for Class2. All Class2 instances should be grouped together at the place that the first Class2 occurs. Here is what the output should be like: List<BaseClass> list = new List<BaseClass>() { new Class1(), new Class2(1), new Class2(2), new Class3(), new Class4() }; I can't for the life of me figure out how to do this...

• Bit Flipping in Hex

  - by freyrs

  I have an 8 digit hexadecimal number of which I need certain digits to be either 0 or f. Given the specific place of the digits is there a quick way to generate the hex number with those places "flipped" to f. For example: flip_digits(1) = 0x000000f flip_digits(1,2,4) = 0x0000f0ff flip_digits(1,7,8) = 0xff00000f I'm doing this on an embedded device so I can't call any math libraries, I suspect it can be done with just bit shifts but I can't quite figure out the method. Any sort of solution (Python, C, Pseudocode) will work. Thanks in advance.

• iPhone StoreKit development: Can't create a test user?

  - by Cruinh

  I'm trying to get up to speed on how to develop an in-app store using the new 3.0 SDK... but I'm a bit stuck in that I don't seem to be able to create a test account. The iTunes Connect FAQ states "To create test users for your sandbox environment, go to the Manage Users section of iTunes Connect and select In App Purchase Test User. Your test users will not have iTunes Connect access. They will just have access to the sandbox environment." ...but when I go to that Manage Users section, there's no mention of any sort of "In App Purschase Test User" or how to make one. Did I miss doing something to enable that? There is another section of that same FAQ that seems to suggest I need to have a paid app in the store first? Is that the reason I can't even use the test environment?

• Catching the redirected address from NSURLConnection

  - by Vic

  I'm working on a software which follows the HTTP redirection which is dynamically calculated by the server depending on a pparameter. I don't want to show the primary server in Mobile Safari but rather the redirected address only. The following code workks: request = [NSMutableURLRequest requestWithURL:originalUrl cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:10]; [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; // Extract the redirected URL target = [response URL]; The problem is that the server requires several seconds to answer. The sendSynchronousRequest blocks the app for this time completely which is messy, I can't even display the "Busy" animation. Does anyone know how I can retrieve the redirected address asynchronously without safari appearance in the meanwhile with the redirecting server URL or display some sort of the "Be patient" animation during the sendSynchronousRequest? What disadvantages would have the passing of sendSynchronousRequest in another thread?

• How to retrieve column total when rows are paginated?

  - by Rick

  Hey guys I have a column "price" in a table and I used a pagination script to generate the data displayed. Now the pagination is working perfectly however I am trying to have a final row in my HTML table to show the total of all the price. So I wrote a script to do just that with a foreach loop and it sort of works where it does give me the total of all the price summed up together however it is the sum of all the rows, even the ones that are on following pages. How can I retrieve just the sum of the rows displayed within the pagination? Thank you! Here is the query.. SELECT purchase_log.id, purchase_log.date_purchased, purchase_log.total_cost, purchase_log.payment_status, cart_contents.product_name, members.first_name, members.last_name, members.email FROM purchase_log LEFT JOIN cart_contents ON purchase_log.id = cart_contents.purchase_id LEFT JOIN members ON purchase_log.member_id = members.id GROUP BY id ORDER BY id DESC LIMIT 0,30";

• OS X Dock API? Retrieve OS X active application's icon with badges and other modifications.

  - by pokstad

  Is there an API for retrieving the icons of the currently open apps on Mac OS X? I am trying to retrieve all the icons of the active applications along with any badges on top of the application (i.e. number of new messages in mail, or current download rate in Transmission). Is there some sort of Dock API? The only mention of an OSX API for retrieving information about currently active applications I have been able to find is the Process Manager API, which does not mention the ability to poll the dock or retrieve icon data.
