• Web-To-Print - What technology should I explore? Web-Content -> drag & drop to Templates -> PDF

  - by hamlin11

  I'm discussing some software design issues with a potential client and the idea of Web-to-Print technology has come up. We need users to be able to drag images from an image library to various regions defined by a template. Example: Images may go in box A, B, or C and text may go in boxes D or E. These templates would be setup Boxes A through E would be defined inside a template by administrators using some sort of editor. These templates would serve as a mapping from web-content to a PDF. Once users drag images and insert text in the appropriate regions of the template, the result will be converted into a PDF. Is this feasible these days with jquery & asp.net? That would be nice. If not, what would be the ideal solution?

• Passing switches to Xcode 3.1 user scripts

  - by MyztikJenz

  I have a user script that would be much more useful if it could dynamically change some of its execution dependent on what the user wanted. Passing simple switches would easily solve this problem but I don't see any way to do it. I also tried embedding a keyword in the script name, but Xcode copies the script to a guid-looking filename before execution, so that won't work either. So does anyone know of a way to call a user script with some sort of argument? (other that the normal %%%var%%% variables) Thanks! EDIT: User scripts are accessible via the script menu in Xcode's menubar (between the Window and Help menus). My question is not about "run script" build phase scripts. My apologies for leaving that somewhat ambiguous.

• can I override/redefine "global" Javascript functions, like confirm() and alert()?

  - by EndangeringSpecies

  I want to do some browser automation, and those pesky confirm/alert boxes are a real pain. Disabling javascript completely in this case is not an option, unfortunately. Well, so I was wondering, can I just change the definition of those methods as seen by my browser's javascript interpreter to basically do nothing and return true? Note that I do know about redefining them in the Javascript code directly, e.g. putting in function alert(message) { return true; } but AFAIK this is not a viable approach for this situation because when doing browser automation I have to work with other people's Javascript. Moreover, my program actually begins manipulating these websites already after the page has fully loaded into the browser, so I cannot just first automatically rewrite the javascript and then load the page. Well, so I was wondering if I could instead just "permanently" modify the way alert/confirm are implemented and executed in my browser. Sort of like the equivalent of dll injection and so forth in the realm of windows apps.

• Need an encrypted online source code backup service.

  - by camelCase

  Please note this is not a question about online/hosted SVN services. I am working on a home based, solo developer, project that now has commercial significance and it is time to think about remote source code backup. There is no need for file level check in/out, all I need is once a day or once a week directory level snapshot to remote storage. Automatic encryption would be a bonus to protect my IP. What I have in mind is some sort of GUI interface app that will squirt a source code snapshot off to an Amazon S3 bucket on an automatic schedule. (My development PC runs on MS Windows.)

• Django openid authentication with google

  - by Zayatzz

  Hello I am looking into authenticating via google. I dont understand how it works:http://code.google.com/apis/accounts/docs/OpenID.html#Samples If i do that 2nd request by entering the data as one url with params into browser i get back XML file. Should i not get back sample response nr3? Can somebody explain this to me? The problem is, that im trying to sort through some third party app that uses google openid authentication and its not recieving authenticated users e-mail back, like in sample response 3. Alan PS i have read through similar questions and their responses and gone through pages like: http://stackoverflow.com/questions/353880/how-does-openid-authentication-works http://www.windley.com/archives/2006/04/how_does_openid.shtml http://tinisles.blogspot.com/2008/02/how-does-openid-work.html http://openid.net/pres/protocolflow-1.1.png etc..

• python multithread "maximum recursion depth exceed"

  - by user293487

  I use Python multithread to realize Quicksort. Quicksort is implement in a function. It is a recursive function. Each thread calls Quicksort to sort the array it has. Each thread has its own array that stores the numbers needs to be sorted. If the array size is smaller (<10,000). It runs ok. However, if the array size is larger, it shows the "maximum recursion depth exceed". So, I use setrecursionlimit () function to reset the recursion depth to 1500. But the program crash directly...

• Is there a way to make vim display "virtual characters" before/after regular patterns in the buffer?

  - by Laurence Gonsalves

  Vim has list and listchars options that make vim display "virtual characters" (by which I mean characters that aren't actually in the buffer) in certain situations. For example, you can make trailing spaces look like something else, or add a visible character to represent the newline character. I'd like to be able to enable the display of certain characters either before or after certain regular patterns ((perhaps syntax items). Sort of like syntax highlighting, but instead of just changing the color/styling of characters that are in the buffer, I'd like to display extra characters that aren't in the buffer. For example, I'd like to display a virtual : (colon) after all occurrences of the word "where" that appear at the end of a line. Is this possible, and if so, what is the necessary vimscript to do it?

• difficulty based time estimation software

  - by Frankie

  Some months ago I found a project-management / time-estimation software that would ask you to sort out your tasks in terms of difficulty (1, 2 or 3) and would then estimate the time you would take to deploy. The system would auto-adapt as you were working. I've forgot the software name. For the past days I've been digging emails and searching Google with no results. Can anyone pin the software name by my description? Its not http://www.fogcreek.com (though I've found it to be a great piece of software. Thank you in advance.

• How do I convert PDF to HTML programmatically?

  - by SoaperGEM

  Are there any classes, COM objects, command line utilities, or anything else that I can make an API for that can convert a PDF to an HTML document? Obviously the conversion might be a little rough since PDFs can contain a lot more than HTML can describe. I found a utility called pdftohtml on Source Forge, but quite honestly it does a horrible job with the conversion. I don't care if the software is free or commercial, but is there anything out there at all that I can incorporate with my own software to do this sort of conversion at least decently? I know Google's developed their own method of doing this, since you can click "View as HTML" on a PDF attached to an email through Gmail, but I was hoping there was something out available to the public. Remember, PDF to HTML. I'm NOT worried about HTML to PDF.

• Java Future and infinite computation

  - by Chris

  I'm trying to optimize an (infinite) computation algorithm. I have an infinte Sum to calculate ( Summ_{n- infinity} (....) ) My idea was to create several threads using the Future < construct, then combine the intermediate results together. My problem hoewer is that I need a certain precision. So I need to constantly calculate the current result while other threads keep calculating. My question is: Is there some sort of result queue where each finished thread can put its results in, while a main thread can receive those results and then either lets the computation continues or terminate the whole ExecutorService? Any Help would really be appreciated! Thanks!

• Cropping an image, saving output to a new file and get crop coordinates

  - by synic

  I'm interfacing with a service that allows you to upload an image, and also upload coordinates of a thumbnail of that image. I'm thinking that (if there isn't some sort of prefab Activity specifically for this) that I can use Android's crop utility. The only problem is that I can't overwrite the original file, the crop window needs to have a custom message (instead of "crop image"), and I'll need the coordinates of the crop. Is this possible? Is there another way to do this without writing my own Activity?

• SHAddToRecentDocs without a file?

  - by Chris Becke

  I was toying with an IRC client, integrating it with the windows 7 app bar. To get a "Frequent" or "Recent" items list one has to call SHAddToRecentDocs API. I want to add recent IRC channels visited to the Windows 7 Jumplist for the IRC application. Now, my problem is, IRC channels don't exist in the file system. And SHAddToRecentDocs seems to insist on getting some sort of file system object. Ive tried to work around it by creating a IShellItem pointing to my application, and giving it a command line to launch the channel. The shell is rebelling however, and thus far has not visibly added any of my "recent document" attempts to the Jumplist. Is there no way to do this without creating some kind of entirely unwanted filesystem object?

• What's the best way to view/analyse/filter huge traces/logfiles?

  - by oliver

  this seems to be a reoccurring issue: we receive a bug report for our software and with it tons of traces or logfiles. since finding errors is much easier when having a visualization of the log messages/events over time it is convenient to use a tool that can display the progression of events in a graph etc. (e.g. wireshark (http://www.wireshark.org) for analyzing network traffic) what tool do you use for such a purpose? the problem with most tools i used so far is that they mercilessly break down when you feed them huge data traces ( 1GB) so some criteria for such a tool would be: can deal with huge input files ( 1 GB) is really fast (so you don't have to get coffee while a file is loading) has some sort of filtering mechanism

• Access variables from a number of sources

  - by mac_55

  I'm creating my first game, and I've currently set up a 'GameState' class, to store player health etc. inside. This class is currently instantiated from the AppDelegate as I need to access it from all over my game. This is fine. For each class I'm working in, I can access the app delegate, and then find the GameState object... however, it seems very messy. I'm tempted to find a way (I'm still a newbie) to define the GameState instance as being some sort of global variable so that I can access it from all over with ease... but my little bit of reading on variable scope makes me uneasy about doing this, even if I knew how. Any ideas of the best way to define and access this class? It'll be used for everything from player health, to items they've found, any personalisation etc. Thanks!

• How to build an interactive search engine web interface using python

  - by asmaier

  I have build a static web interface for searching data from some tables in my PostgreSQL database. The query website consists of a simple textfield for entering the search term, the result website presents the results as a simple html table. The server side code for searching the PostgreSQL database and returning the results is written in python using psycopg2. Now I would like to add some interactive "Ajax features" to my search engine. When entering the search term I would like to be able to see a list of possible search terms like Google does it. On the results page, I would like to be able to sort the table showing the results. What would be the easiest/recommended way to implement these features for my search engine web site? Do I need a full-fledged web framework like Django for that?

• Writing a Compiler for .net - IL or Bytecode?

  - by Michael Stum

  I'm currently diving into the inner workings of .net, which means IL. As an exercise, I want to build a brainf..k compiler for .net (yes, they already exist, but as said it's for learning purposes). For the moment I'm just writing some text files that contain .il and compile them with ilasm, which works. But I wonder if I could/should go one level deeper and write bytecode directly? My "concern" is the Windows PE Stuff when compiling an EXE - instead of ilasm I would need some sort of Bytecode linker that would take my MSIL/CIL bytecode and generate the PE Stuff for it? Or do compilers "only" compile their language to IL and execute ilasm? Is there a managed version of it that I can call/embed from my compiler?

• UITableView and keyboard scrolling problem

  - by Jonathan

  after a lot of trial and error, I'm giving up and asking the question. I've seen a lot of people with similar problems but can't get all the answers to work right. I have a UITableView which is composed of custom cells. The cells are made of 5 text fields next to each other (sort of like a grid). When I try to scroll and edit the cells at the bottom of the UITableView, I can't manage to get my cells properly positioned above the keyboard. I have seen many answers talking about changing view sizes,etc... but none of them has worked nicely so far. Could anybody clarify the "right" way to do this with a concrete code example? Thanks in advance, Jonathan

• how to commit 'commit log' itself in same svn version?

  - by understack

  It might sound unnecessary, but let me explain my problem first. Probably then it would make sense. Few artists keep updating images based on clients' change requests. An artist makes changes accordingly and commits with proper 'commit messages'. Just before actual commit, I want to create a text file with image properties like size and all the 'commit messages'. And then this file would be committed itself. So basically some sort of pre-commit processing is required. Even though most of the artists are not very comfortable with svn, they can always see what changes were made last time to the image via simple text file. So artists only do update and commit with svn. How this could be done? Are there any better alternatives?

• Switching to Linux for Windows development, bad idea?

  - by krebstar

  I was contemplating switching to Linux for C++ development, coming from a Windows environment. Is this a bad idea? My workplace uses Windows and Visual Studio for our projects (some C# and java too, but right now I'm only developing in C++). If they decide to put me on a C# project, would development still possible (mono?)? What are the difficulties in this sort of transition? Would I have a problem working on their projects and vice versa? I read somewhere that there'd be problems with precompiled headers and such (we do use them), and encodings (tabs/spaces, line endings, etc).. If it's not too hard to do this switch, how do I get started? IDE? vim+make? Thanks. By the way, we make MOSTLY windows software.. EDIT: Thanks guys, I guess that makes sense..

• REST, caching, and authorizing with multiple user roles

  - by keithjgrant

  We have a system with multiple different levels of access--sometimes even for the same user as they switch between multiple roles. We're beginning a discussion on moving over to a RESTful implementation of things. I'm just starting to get my feet wet with the whole REST thing. So how do I go about limiting access to the correct records when they access a resource, particularly when taking caching into consideration? If user A access example.com/employees they would receive a different response than user B; user A may even receive a different response as he switches to a different role. To help facilitate caching, should the id of the role be somehow incorporated into the uri? Maybe something like example.com/employees/123 (which violates the rules of REST), or as some sort of subordinate resource like example.com/employees/role/123 (which seems silly, since role/### is going to be appended to URIs all over the place). I can help but think I'm missing something here.

• Double linking array in Python

  - by cdecker

  Since I'm pretty new this question'll certainly sound stupid but I have no idea about how to approach this. I'm trying take a list of nodes and for each of the nodes I want to create an array of predecessors and successors in the ordered array of all nodes. Currently my code looks like this: nodes = self.peers.keys() nodes.sort() peers = {} numPeers = len(nodes) for i in nodes: peers[i] = [self.coordinator] for i in range(0,len(nodes)): peers[nodes[i%numPeers]].append(nodes[(i+1)%numPeers]) peers[nodes[(i+1)%numPeers]].append(nodes[i%numPeers]) # peers[nodes[i%numPeers]].append(nodes[(i+4)%numPeers]) # peers[nodes[(i+4)%numPeers]].append(nodes[i%numPeers]) The last two lines should later be used to create a skip graph, but that's not really important. The problem is that it doesn't really work reliably, sometimes a predecessor or a successor is skipped, and instead the next one is used, and so forth. Is this correct at all or is there a better way to do this? Basically I need to get the array indices with certain offsets from each other. Any ideas?

• Computer Quiz Management Software

  - by Asad Jibran Ahmed

  My university is holding a quiz contest in 2 weeks, and I need some sort of software (desktop or web based) that can be used to manage the quiz. I need functionality like an admin panel for adding teams, creating matches between 2 teams, adding questions and answers. I then need the software to automatically display the questions, accept answers, and display and store results. Is there any software (open source/freeware) that I can use for this task. If a pre-built software is not available, which language+library+platform would you suggest I make the software in. It can be either web based or a desktop app. But I need it by 2 weeks. Any suggestions?

• insertNewObjectForEntityForName: inManagedObjectContext: returning NSNumber bug?

  - by beinstein

  I'm relatively well versed in CoreData and have been using it for several years with little or no difficulty. All of a sudden I'm now dumbfounded by an error. For the life of me, I can't figure out why insertNewObjectForEntityForName:inManagedObjectContext: is all of a sudden returning some sort of strange instance of NSNumber. GDB says the returned object is of the correct custom subclass of NSManagedObject, but when I go to print a description of the NSManagedObject itself, I get the following error: *** -[NSCFNumber objectID]: unrecognized selector sent to instance 0x3f26f50 What's even stranger, is that I'm able to set some relationships and attributes using setValue:forKey: and all is good. But when I try to set once specific relationship, I get this error: *** -[NSCFNumber entity]: unrecognized selector sent to instance 0x3f26f50 Has anyone ever encountered anything like this before? I've tried clean all targets, restarting everything, even changing the model to the relationship in question is a to-one instead of a to-many. Nothing makes any difference.

• python dict update diff

  - by adam

  Does python have any sort of built in functionality of notifying what dictionary elements changed upon dict update? For example I am looking for some functionality like this: >>> a = {'a':'hamburger', 'b':'fries', 'c':'coke'} >>> b = {'b':'fries', 'c':'pepsi', 'd':'ice cream'} >>> a.diff(b) {'c':'pepsi', 'd':'ice cream'} >>> a.update(b) >>> a {'a':'hamburger', 'b':'fries', 'c':'pepsi', 'd':'ice cream'} I am looking to get a dictionary of the changed values as shown in the result of a.diff(b)

• SetSel on EN_SETFOCUS or WM_SETFOCUS doesn't work

  - by Coder

  I've ran into next mystic thing in Winapi/MFC, I have an edit box, contents of which I have to select on Tab, Lclick, Rclick, Mclick and so on. The sort of obvious path is to handle the SETFOCUS message and call SetSel(0, -1), which should select all text. But it doesn't work! What's wrong? I tried googling, everyone seems to override Lclilks or handle SetSel in parent windows, but this is wrong from encapsulation point of view, also multiple clicks (user wants to insert something in the middle of the text) will break, and so on. Why isn't my approach working, I tried like 10 different ways, tried to trap all possible focus messages, looked up info on MSDN, but nothing works as expected. Also, I need to recreate the carret on focus, which also doesn't seem to work. SETFOCUS message gets trapped alright. If I add __asm int 3, it breaks every time. It's the create carret and setsel that gets swallowed it seems.
