• How to normalize a database where different user groups have different kinds of profiles?

  - by Stephen

  My application database has a Groups table that separates users into logical roles and defines access levels (admin, owner, salesperson, customer service, etc.) Groups has many Users. The Users table contains login details such as username and password. Now I wish to add user profiles to my database. The trouble I'm having (probably due to my relative unfamiliarity with proper database normalization) is that different user groups have different kinds of profiles. Ergo, a salesperson's profile will include his commission percentage, whereas an admin or customer service would not need this value. So, would the proper method be to create a unique profile table for each group? (e.g. admin_profiles, or salesperson_profiles). or is there a better way that combines certain details in a generic profile, while some users have extended info. And if so, whats a good example of how to do this with the commission example given?

• What time function do I need to use with pthread_cond_timedwait?

  - by Vincent

  The pthread_cond_timedwait function needs an absolute time in a time timespec structure. What time function I'm suppose to use to obtain the absolute time. I saw a lot of example on the web and I found almost all time function used. (ftime, clock, gettimeofday, clock_gettime (with all possible CLOCK_...). The pthread_cond_timedwait uses an absolute time. Will this waiting time affected by changing the time of the machine? Also if I get the absolute time with one of the time function, if the time of the machine change between the get and the addition of the delta time this will affect the affect the wait time? Is there a possibility to wait for an event with a relative time instead?

• What jquery code or plugin would I use to update the position of an element created by a plugin

  - by Breadtruck

  I am using a jquery plugin from [ FilamentGroup ] called DateRangePicker. I have a simple form with two text inputs for the start and end date that I bind the DateRangePicker to using this $('input.tbDate').daterangepicker({ dateFormat: 'mm/dd/yy', earliestDate: new Date(minDate), latestDate: new Date(maxDate), datepickerOptions: { changeMonth: true, changeYear: true, minDate: new Date(minDate), maxDate: new Date(maxDate) } }); I have a collapsible table above this form that when shown, moves the form and the elements that the daterangepicker plugin is bound to, down lower on the page, but the daterangepicker appears to keep the position from when it was actually created. What code could I put in the daterangepicker's onShow Callback to update its position to be next to the element is was initially bound to? Or is there some specific jquery method or plugin that I could chain to the daterangepicker plugin so that it will update its position correctly. This would come in handy for some other plugins that I use that don't seem to keep their position relative to other elements correctly either.

• Windows Server 2003

  - by user229133

  I have a website that is using Windows Server 2003. The site is called https://mysite.com/ and at ip address 111.1.1.1. Now when I log into the site all my relative links that are generated using NavURL (<%# NavURL("Images/Menu/img.gif")%) are saying "http://111.1.1.1/Images/Menu/img.gif" instead of "https://mysite.com/Images/Menu/img.gif". This is causing an error because it needs to be secure. I'm sure there is a setting on the server somewhere to point to the name and not the ip, but I don't know where. Thanks for your help.

• Web.xml: Are url-pattern tags relitive to each other?

  - by sixtyfootersdude

  <servlet-mapping> <servlet-name>myName</servlet-name> <url-pattern>/aName</url-pattern> </servlet-mapping> <security-constraint> <web-resource-collection> ... <url-pattern> /* </url-pattern> </web-resource-collection> ... </security-constraint> This is an excerpt from web.xml (using it to configure a jboss/tomcat webservice).

• iPhone framework paths?

  - by user158103

  I recently moved my projects to a new mac, along with a newer version of Xcode. When i opened my project i noticed that some files were red. So i remapped them by setting the path (by project path) and then providing the proper path location. Now my problem is that the frameworks that i have are red, and i cant find their location! I did set the framework paths to be "relative to current SDK" however. Can anybody help me get my frameworks mapped correctly? The frameworks im using are: - QuartzCore.framework - libsqlite3.0.dylib - UIKit.framework - Foundation.frameowrk - CoreGraphics.framework The XCode version is 3.1.4 (the only one installed). The iPhone app was originally created using a prior version of Xcode (i dont remember which version).

• Implementing zoom on a fixed point, javascript/canvas

  - by csiz

  I want to implement zooming on the mouse pointer with the mouse wheel. That is scaling the image while the point under the mouse pointer stays fixed. Here is my code, which doesn't work very well var scala = 1 + event.wheelDelta / 1000; canvas.context.translate(-canvas.mouse.x * ( scala - 1 ) / canvas.scale,-canvas.mouse.y * ( scala - 1 ) / canvas.scale); canvas.context.scale(scala,scala); canvas.scale *= scala; //canvas.scale is my variable that is initially set to 1. //canvas.mouse is my variable that represents the mouse position relative to the canvas

• FileNotFound exception

  - by Pratik

  I am trying to read a file in a servlet. I am using eclipse IDE. I get a FileNotFoundException if I provide relative file name. List<String> ls=new ArrayList<String>(); Scanner input = new Scanner(new File("Input.txt")); while(input.hasNextLine()) { ls.add(input.nextLine()); } The same code works if I put the absolute path like this: Scanner input = new Scanner(new File("F:/Spring and other stuff/AjaxDemo/src/com/pdd/ajax/Input.txt")); The Java file and text file are there in the same folder. Does it searches text file in some other folder ?

• EditText and Button on the same line with Textiew underneath?

  - by Kevin

  Hi, I am trying to have an EditText widget next to a button with a text view underneath. The EditText should resize and fill the screen accordingly, while the button's width is always only what it needs to be by setting the width to wrap_content. The layout should not be relative. Below is the code I have so far some of which was found here on StackOverflow. Removing the text view gives the desired appearance for the EditText and button, but when the TextView is added the view goes to ... well. Not sure why the code is not showing? I put it into a < code< pre block without success. http://pastebin.com/WgH6qrTm

• Best choice for off-site backup: dd vs tar

  - by plok

  I have two 1TB single-partition hard disks configured as RAID1, of which I would like to make an off-site backup on a third disk, which I am still to buy. The idea is to store the backup at a relative's house, considerably far away from my place, in the hope that all the information will be safe in the case of a global thermonuclear apocalypse. Of course, this backup would be well encrypted. What I still have to decide is whether I am going to simply tar the entire partition or, instead, use dd to create an image of the disks. Is there any non-trivial difference between these two approaches that I could be overlooking? This off-site backup would be updated no more than two or three times a year, in the best of the cases, so performance should not be a factor to be pondered at all. What, and why, would you use if you were me? dd, tar, or a third option?

• Ruby - Is there a way to overwrite the __FILE__ variable?

  - by Markus Orrelly

  I'm doing some unit testing, and some of the code is checking to see if files exist based on the relative path of the currently-executing script by using the FILE variable. I'm doing something like this: if File.directory?(File.join(File.dirname(__FILE__),'..','..','directory')) blah blah blah ... else raise "Can't find directory" end I'm trying to find a way to make it fail in the unit tests without doing anything drastic. Being able to overwrite the __ FILE __ variable would be easiest, but as far as I can tell, it's impossible. Any tips?

• CSS: Centering a floated block level element in IE6 (It almost works)

  - by Louis W

  I have a block level element which I am centering on the page. I have gotten it to work for all other browsers except IE6 where it ALMOST works. http://tinyurl.com/28sh9eq If I view the page in IE6 the red box is slightly off center of the pink one in IE. If I then resize the browser window it snaps into place where I want it. Uhhhhh.... yea.... what gives? How come resizing the window makes it work? I have also tried setting an explicit width on the wrapper with no avail. <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"> <html> <head> <title></title> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <meta http-equiv="X-UA-Compatible" content="IE=7" /> <style type="text/css"> BODY { text-align: center; font-family: Arial; } .row_wrap { height: 100px; margin-bottom: 30px; background-color: pink; } .row { float: right; position: relative; left: -50%; text-align: left; clear: both; } .button1 { color: #FFF; height: 36px; text-decoration: none; position: relative; padding: 0 30px; background: url('button.gif') no-repeat 0 0; display: block; float: left; left: 50%; } .button1 .end { width: 20px; height: 37px; position: absolute; right: -2px; top: 0; background: url('button.gif') no-repeat right 0; } .button1 .text { font-size: 16px; font-weight: bold; white-space: nowrap; height: 36px; padding-top: 7px; display: block; float: left; } .button1 .text .arrow { vertical-align: 1px; } </style> </head> <body> <h2>RTL: Button 1</h2> <div class="row_wrap"> <div class="row" dir="rtl"> <a href="#" class="button1"> <span class="end"></span> <span class="text"><span class="arrow">»</span> Hello 1.</span> </a> </div> </div> <h2>RTL: Button 1-2</h2> <div class="row_wrap" style="width: 400px;"> <div class="row" dir="rtl"> <a href="#" class="button1"> <span class="end"></span> <span class="text"><span class="arrow">»</span> Hello 1.</span> </a> </div> </div> <br/><br/> <h2>Normal: Button 1</h2> <div class="row_wrap"> <div class="row"> <a href="#" class="button1"> <span class="end"></span> <span class="text"><span class="arrow">»</span> Hello.</span> </a> </div> </div> </body> Thanks for your help.

• django filefield return filename only in template

  I've got a field in my model of type FileField. This gives me an object of type type File, which has the following method: File.name: The name of the file including the relative path from MEDIA_ROOT. What I want is something like .filename that will only give me the filename and not the path as well something like: {% for download in downloads %} <div class="download"> <div class="title">{{download.file.filename}}</div> </div> {% endfor %} which would give something like myfile.jpg thanks

• Inner join 2 tables one to many 2 where clauses

  - by user2892350

  I'm a relative rookie at this,so please bear with me... I have 2 tables: OrderDetail and OrderMaster...both have a column named SalesOrder. OrderDetail table has multiple rows per unique SalesOrder. OrderMaster table has one row per unique SalesOrder. OrderDetail has a column named LineType. OrderMaster has a column named OrderStatus. I want to select all records from OrderDetail that have a LineType of "1" AND whose matching SalesOrder line in the OrderMaster table has a OrderStatus column value of "4". In plain English, orders with a Status 4 are open and ready to ship, LineType value of 1 means the Detail Line is a product code. How should this query be structured? It's going into VS 2008 (VB). Many thanks in advance!!! Mike

• In DirectShow, what determines the graph source?

  - by Seva Alekseyev

  Hi all, I have two machines - A (XP SP2) and B (Win7). Machine B has trouble playing OGM files - enabling subtitles causes a crash in the player. Investigation shows that the DirectShow graphs are quite different. On A, the source is a file source, which produces a stream of subtype OGG, which goes into "Ogg Splitter". On B, the source is an instance of Haali Media Splitter, which produces video, audio, and subtitles as separate streams. Machine A has Haali splitter installed as well, but it is not invoked somehow. Question - what determines the source filter? Is there a file type to preferred source mapping, or does the system load and ask all suitable filters if they would take this file? On machine A, the merit of Haali splitter is higher than that of File source, so it's probably not about relative merits.

• Stacking Dialogs in Android

  - by ChaimKut

  Is there a way to control the relative stacking of Dialogs produced by your own Activity? For instance, there are some more important Dialogs which I would like to ensure are on top and if another Dialog wants to pop up I would want it to pop under the important Dialogs. Example: I want to present to the user an important dialog, Dialog A. The activity realizes that there is a dialog, Dialog B, of lesser importance to display to the user. Is it possible to specify Dialog B to be under Dialog A so that when Dialog A is cleared, Dialog B will be seen by the user? I know that the onDismiss interface exists, but this necessarily ties Dialog A and Dialog B together. I want the Dialogs to be independent and would prefer to use a higher level abstraction like the window stack responsible for ordering the Dialogs.

• JAR file folder for eclipse projects

  - by Daff

  I'm trying to create a centralized folder (in some kind of a "meta project" in my eclipse workspace) for commonly used JAR files for referenced projects in this workspace. It should work similar to the WEB-INF/lib folder for web projects but also apply to non web projects, and automatically scan and add all jar files in this folder. I tried to create a user library with these jar files and reference them in the project but I still have to add every new jar manually to the user library (and don't know if it is referenced relative of absoulute) and Tomcat (WTP) doesn't seem to take these files (Run As - Run on Server) into its classpath (and I don't want to duplicate the jars and put them into WEB-INF/lib). Any ideas?

• Information Modeling

  - by Betamoo

  The sensor module in my project consists of a rotating camera, that collects noisy information about moving objects in the surrounding environment. The information consists of distance, angle and relative change of the moving objects.. The limiting view range of the camera makes it essential to rotate the camera periodically to update environment information... I was looking for algorithms / ways to model these information, in order to be able to guess / predict / learn motion properties of these object.. My current proposed idea is to store last n snapshots of each object in a queue. I take weighted average of positions and velocities of moving object, but I think it is a poor method... Can you state some titles that suit this case? Thanks
