• Resizing page format on iReport

  - by pringlesinn

  I've been trying to print a pdf made from iReport in less than a page A4. it's like half A4 page height. I'm using a Line Matrix printer, doesn't matter which one. So, when I try to print 2 files at same file, it should print everything on the right place, but just first file is printed correctly. The second one is based on a A4 page format, and just starts printing after A4 page height is over, skipping a big blank. Where can I set the size of page in iReport? The only thing I could do was setting size of what is shown on screen while I edit the file. I tried my best to explain the situation, any doubts, ask me and I'll try even harder.

• iPhone SDK: How to detect a row-hit while in the editing mode?

  - by Carol

  I've looked everywhere and I can't find it. I have a UITableView that contain rows of "checkmark" cells. The user clicks on a row to check/uncheck it. (It works!!!!) But I also want to allow the user to EDIT the data on that row. ... so I have an "EDIT" button at the top. The user hits it and is allowed to DELETE any rows. (That works too!!!!) But how do I also detect a "tap" on that row. Where is there some kind of a didSelectRowAtIndexPathWhileInEditMode ???? (Is that really the best way to do this: Allow "selections", and "deletions", and "editing" of each row?)

• Animation with Initial Velocity

  - by abustin

  I've been trying to solve this problem for a number of days now but I must be missing something. Known Variables: vi = Initial Velocity t = Animation Duration d = Distance The function I'm trying to create: D(t) = the current distance for a given time Using this information I want to be able to create a smooth animation curve with varying velocity (ease-in/ease-out). The animation must be able ease-in from an initial velocity. The animation must be exactly t seconds and must be travel exactly d units. The curve should lean towards the average velocity with acceleration occurring at the beginning and the end portions of the curve. I'm open to extra configuration variables. The best I've been able to come up with is something that doesn't factor in the initial velocity. I'm hoping someone smarter can help me out. ;) Thank you! p.s. I'm working with an ECMAScript variant

• Window title for a console application

  - by Timbo

  In Visual Studio's Attach to Process dialog, one of the columns in the Available Processes list is "Title", which lists the title of the topmost window owned by each process. We spawn multiple instances of several server processes in order to compartmentalize the work. For these console processes, the Title field is blank, so currently we have to look up the process id in our management tool in order to find the correct process. In order to streamline the debugging process, I would love to be able to use the Title field to directly determine which process I want. SetConsoleTitle does not do the trick, nor SetWindowText with a NULL hWnd. To the best of my knowledge, a console application does not intrinsically own any window handles that we could pass to SetWindowText. We don't want to create any visible windows for these server processes. Any suggestions for a reasonable way to trick Visual Studio into displaying some useful information here?

• How do I create a web service with rails?

  - by NotDan

  I have a silverlight application that needs to talk to a rails app to add a record. I have been able to get the silverlight app to successfully do the POST assuming everything goes good. Now, however, I need to be able to make it more robust and have the rails app return error/success messages to the silverlight app in a format it can read (xml maybe?). I can modify the rails app and silverlight app as needed. What is the best way to accomplish this with rails?

• How to save search, choose a recent search and then populate the form using jQuery and/or asp.net

  - by user187870

  I want to do something similar to what priceline does. It saves the recent searches in a dropdown menu. When you pick one from the recent search. The form will be populated accordingly. (See screen shot http://yfrog.com/5fscreenshot20100501at105p) This is what I am thinking. (1) Save the searches into an array in a cookie (2), when a recent search item is chosen, retrive the corresponding array element from the cookie and then populate the form. What do you think is the best way to implement this? I especially want to know how to save the form entries into the cookie and how to populate the form.

• How do I apply css for textboxes only but not for all the <input> types like CheckBoxes, etc.?

  - by George

  If all browsers supported attribute selectors, we could easily do the following: input[type='text'] { font:bold 0.8em 'courier new',courier,monospace; } input[type='radio'] { margin:0 20px; } input[type='checkbox'] { border:2px solid red; But I don't think all IE versions of ^ and greater support this. I think I'd like to avoid skins. Not sure why, other than I tried them and I recall having a negative experience. It was probably my lack of knowledge. Are there any issues in using and CSS, external or otherwise? What's the best way to handle this? Currently I am assigning separate classes to each control type.

• Can I use "Online Backup" to backup my DVS instead of pushing to an external repo?

  - by Matt Brailsford

  Hi Guys, I'm currently signed up with a third party service that hosts my mercurial repositories as a central hub to push my changes to as a sort of backup. Now, I'm looking at a system to backup my laptop and am concidering Mozy. I'm a loan developer, and work on a laptop and am usualy connected to my internet via wifi with my laptop only really being on when I'm working, so feel something like Mozy is my best option. My question is, if I'm the only developer, could I get away with just using local mercurial repos and using Mozy to backup everything up? Rather than pushing to an external repo? Many thanks Matt

• Performing AJAX calls on the "new" controller

  - by shmichael

  In my rails app, I want to have a sortable list as part of an object creation. The best practice suggested Railscast adds the acts_as_list plugin and then initiates AJAX calls to update item position. However, AJAX calls won't work on an unsaved model, which is the situation with new. One solution would be to save the model immediately on new and redirect to edit. This would have a nice side effect of persisting any change so the user could resume work should he be interrupted. However, this solution adds the unwanted complexity of saving an invalid model, compromising rails' validation processes. Is there any better way to allow AJAX + validations without going into too much work?

• Storing millions of URLs in a database for fast pattern matching

  - by Paras Chopra

  I am developing a web analytics kind of system which needs to log referring URL, landing page URL and search keywords for every visitor on the website. What I want to do with this collected data is to allow end-user to query the data such as "Show me all visitors who came from Bing.com searching for phrase that contains 'red shoes'" or "Show me all visitors who landed on URL that contained 'campaign=twitter_ad'", etc. Because this system will be used on many big websites, the amount of data that needs to log will grow really, really fast. So, my question: a) what would be the best strategy for logging so that scaling the system doesn't become a pain; b) how to use that architecture for rapid querying of arbitrary requests? Is there a special method of storing URLs so that querying them gets faster? In addition to MySQL database that I use, I am exploring (and open to) other alternatives better suited for this task.

• How should I move my code from dev to production?

  - by Teddy

  I have created a PHP web-application. I have 3 environments: DEV, TEST, PROD. What's a good tool / business practice for me to move my PHP web-application code from DEV to TEST to the PROD environment? Realizing that my TEST environment still only connects to my TEST database; whereas, I need to PROD environment to connect to my PROD database. So the code is mostly the same, except that I need to change my TEST code once moved into PROD to connect to the PROD database and not TEST database. I've heard of people taking down Apache in such away that it doesn't allow new connections and once all the existing connections are idle it simply brings down the web server. Then people manually copy the code and then manually update the config files of the PHP application to also point to the PROD instance. That seems terribly dangerous. Does a best practice exists?

• Entity Framework associations killing performance

  - by Chris

  Here is the performance test i am looking at. I have 8 different entities that are table per type. Some of the entities contain over 100 thousand rows. This particular application does several recursive calculations on the client so I think it may be best to preload the data instead of lazy loading. If there are no associations I can load the entire database in about 3 seconds. As I add associations in any way the performance starts to drastically decline. I am loading all the data the same way (just calling toList() on the entity attached to the context). I ran the test with edmx generated classes and self tracking entities and had similar results. I am sure if I were to try and deal with the associations myself, similar to how I would in a dataset, the performance problem would go away. On the other hand I am pretty sure this is not how the entity framework was intended to being used. Any thoughts or ideas?

• OpenGL: Textured Primitives + High Framerate

  - by James D

  Short version: What's the best practice going forward for efficiently rendering large numbers of independent texture-mapped, lighted 2D/3D primitives (circles, rects, etc.) in OpenGL? For example: a typical particle system using billboarded quads/triangles, point sprites, or whatever other technique, with blending. Because after reading this thread on the messiness of OpenGL versioning/deprecation I'm starting to have my doubts. My specific question is not the ABCs of displaying primitives in OpenGL, but rather how to do so efficiently in post-deprecation (or pre-deprecation) OpenGL, in a way that's going to be compatible with a wide range of commodity hardware and in a way that's not going to break or itself get deprecated, five years down the line. Thanks!

• Ruby on Rails: reducing complexity of parameters in a RESTFul HTTP POST request (multi-model)

  - by randombits

  I'm using cURL to test a RESTFul HTTP web service. The problem is I'm normally submitting a bunch of values normally like this: curl -d "firstname=bob&lastname=smith&age=25&from=kansas&someothermodelattr=val" -H "Content-Type: application/x-www-form-urlencoded" http://mysite/people.xml -i The problem with this is my controller will then have code like this: unless params[:firstname].nil? end unless params[:lastname].nil? end // FINALLY @person = People.new(params[:firstname], params[:lastname], params[:age], params[:from]) etc.. What's the best way to simplify this? My Person model has all the validations it needs. Is there a way (assuming the request has multi-model parameters) that I can just do: @person = People.new(params[:person]) and then the initializer can take care of the rest?

• web developer editor ubuntu

  - by madphp

  Hi, I know theres hundred of questions and answers out there, but cant find one to specifically answer this. I need a web editor that will let me choose a dark themed editor. I understand gvim is one, but im not totally ready to let go of my mouse. I would like something like sublime text editor for windows, but open to other suggestions. The less bloat the best. I dont need a full IDE like eclipse, but willing to compromise, as long as the themes can easily be added. I've tried bluefish, kompozer and not happy with them. Just need a basic text editor that will highlight php syntax on a dark background.

• Updating Linking Tables

  - by Sasha

  I've currently adding a bit of functionality that manages holiday lettings on top of a CMS that runs on PHP and MySQL. The CMS stores the property details on a couple of tables, and I'm adding a third table (letting_times) that will contain information about when people are staying at the property. Basic functionality would allow the user to add new times when a guest is staying, edit the times that the guest is staying and remove the booking if the guest no longer wants to stay at the property. Right now the best way that I can think of updating the times that the property is occupied is to delete all the times contained in the letting_times database and reinsert them again. The only other way that I can think to do this would be to include the table's primary key and do an update if that is present and has a value, otherwise do an insert, but this would not delete rows of data if they are removed. Is there a better way of doing this?

• Program occasionally stuck when writing to ldap

  - by djerry

  hey guys, I have 2 databases for my program : mysql and ldap. All transactions happen to mysql, but i need ldap to connect to ip-phones. There's an option to synchronise the ldap database. So when the ldap is brand new, and mysql contains like 200+ records, it may want to update. But when inserting all those entries, it "freezes". It never happens at the same record, it's very random. Sometimes after 70 records, sometimes at 200 the program quits inserting, and gets stuck. This is very annoying. My best guess is that ldap can't handle that much inserts in a short time. Code isn't the problem, as it is a random problem. Does this seem familiar to somebody or is it just me? Thanks in advance.

• Multiple Inheritance in LINQtoSQL?

  - by Bumble Bee

  Guys, I have been surfing thru the web to find a way that I could use Multiple-Table-Inheritance in LINQ-To-SQL. But it looks like that it only supports single table inheritance which is not the best way to achieve inheritance in a ORM framework. I got to read that this will be addressed in next LINQ and Entity framework implementations. But how longer a stay we are talking about? In the meantime, if any of you guys have tried out a work-around implementation to achieve this, please let me know. And I thought of using my leisure time to come up with such an implementation so suggestions are welcome! /Bumble Bee

• analysis Big Oh notation psuedocode

  - by tesshu

  I'm having trouble getting my head around algorithm analysis. I seem to be okay identifying linear or squared algorithms but am totally lost with nlogn or logn algorithms, these seem to stem mainly from while loops? Heres an example I was looking at: Algorithm Calculate(A,n) Input: Array A of size n t?0 for i?0 to n-1 do if A[i] is an odd number then Q.enqueue(A[i]) else while Q is not empty do t?t+Q.dequeue() while Q is not empty do t?t+Q.dequeue() return t My best guess is the for loop is executed n times, its nested while loop q times making NQ and the final while loop also Q times resulting in O(NQ +Q) which is linear? I am probably totally wrong. Any help would be much appreciated. thanks

• Store web content in XML using wiki markup

  - by Mike

  Does anyone have an XML style sheet that'll convert wiki-like markup to HTML? Or is that a bad idea? I only found one style sheet that'll convert HTML to wiki-like markup, view-source:http://mozile.mozdev.org/0.8/demos/html2wiki.xsl . Or is this a bad idea? Basically, instead of following strict rules with my XML tags to format my content, I thought it'd be best to have something like this: <content> \## This is my heading </content> That way I'm free to display my content however I feel without having to modify my style sheet. Any ideas?

• Any tips of how to handle hierarchical trees in relational model?

  - by George

  Hello all. I have a tree structure that can be n-levels deep, without restriction. That means that each node can have another n nodes. What is the best way to retrieve a tree like that without issuing thousands of queries to the database? I looked at a few other models, like flat table model, Preorder Tree Traversal Algorithm, and so. Do you guys have any tips or suggestions of how to implement a efficient tree model? My objective in the real end is to have one or two queries that would spit the whole tree for me. With enough processing i can display the tree in dot net, but that would be in client machine, so, not much of a big deal. Thanks for the attention

• Traverse list to add elements using .NET

  - by Addie

  I have a list of objects. Each object has an integer quantity and a DateTime variable which contains a month and year value. I'd like to traverse the list and pad the list by adding missing months (with quantity 0) so that all consecutive months are represented in the list. What would be the best way to accomplish this? Example: Original List { Jan10, 3 }, { Feb10, 4 }, { Apr10, 2 }, { May10, 2 }, { Aug10, 3 }, { Sep10, -3 }, { Oct10, 6 }, { Nov10, 3 }, { Dec10, 7 }, { Feb11, 3 } New List { Jan10, 3 }, { Feb10, 4 }, {Mar10, 0}, { Apr10, 2 }, { May10, 2 }, { Jun10, 0 }, { Jul10, 0 } { Aug10, 3 }, { Sep10, -3 }, { Oct10, 6 }, { Nov10, 3 }, { Dec10, 7 }, { Jan11, 0 }, { Feb11, 3 }
