• How to use the correct Google OpenID url to login to my site?

  - by Michael Mao

  Hello everyone: I am trying to implement OpenID as one preferred option to my next web app here The code is taken from this tutorial and works if I use my openID from myopenid.com However, I believe most people would just love to use their everyday email address as their openID, as far as I know, Google, Yahoo, and some other big players have already done this in their systems. My question is: how could I find the correct "url" to enter in the form to login? I used my Google OpenID account for StackOverflow and it works just fine. I try to copy my openID like this: www.google.com/accounts/o8/id?id=aitoawllano10bzdzp3ht0diffry0qt6_j2ls-m And paste it directly into my form, but it doesn't work. I also tried to remove the url parameter, but that won't do, either. Thanks a lot in advance for any tips and suggestions.

• How do sprites work?

  - by Alan

  How do sprites work? I've seen sprites from old school games like Super Mario Brothers, and wondered how they're animated to make a game. They're always presented as one big image map, so how are they used? For Mario (as an example) are there precalculated image co-ordinates that outline mario, and are swapped between various mario sprites to produce animation? Or are sprites pre "cut" during game initialization using precalculated images co-ordinates and stored in memory somewhere? Obviously I know nothing about game development.

• What are some of the practical cons to using ASMX webservices?

  - by Earlz

  Hello, at my workplace we are about to start a big project. My boss (a programmer, this is a startup) wishes to use ASMX webservices for this purpose. I do not want to start off a new program using deprecated technology and would like to show him this. I dislike WCF at this moment because it has such an extreme learning curve, but I'd rather learn it than use an unsupported technology. The problem I'm having is that I can not find any practical list of cons and downfalls when compared to WCF so that I can convince my boss to not use them. And saying "it's not as powerful" is not an adequate explanation. What exactly can it not do that we may need it to do for a webservice that is not meant to be shared externally? (as in, we don't support third-parties using our webservices unless they are using one of our clients. )

• how to make tooltip move along with mouse?

  - by George2

  Hello everyone, I am using Silverlight 3 + VSTS 2008. I have a image (Multiscale image control) and I place tooltip on this image. The function of Tooltip works fine. Since the image is big (about 500 * 500 size), and since end user could move mouse on the picture, and I want to display tooltip position along with the mouse (i.e. when mouse moves, I want to tooltip move along with the mouse). Currently, the tooltip displays at a fixed position. Here is my current XAML code, any ideas how to solve this issue? <MultiScaleImage x:Name="msi" Height="500" Width="500"> <ToolTipService.ToolTip> <ToolTip Content="Here is a tool tip" Name="DeepZoomToolTip"></ToolTip> </ToolTipService.ToolTip> </MultiScaleImage> thanks in advance, George

• graphviz segmentation fault

  - by LucaB

  Hi I'm building a graph with many nodes, around 3000. I wrote a simple python program to do the trick with graphviz, but it gives me segmentation fault and I don't know why, if the graph is too big or if i'm missing something. The code is: #!/usr/bin/env python # Import graphviz import sys sys.path.append('..') sys.path.append('/usr/lib/graphviz') import gv # Import pygraph from pygraph.classes.graph import graph from pygraph.classes.digraph import digraph from pygraph.algorithms.searching import breadth_first_search from pygraph.readwrite.dot import write # Graph creation gr = graph() file = open('nodes.dat', 'r') line = file.readline() while line: gr.add_nodes([line[0:-1]]) line = file.readline() file.close() print 'nodes finished, beginning edges' edges = open('edges_ok.dat', 'r') edge = edges.readline() while edge: gr.add_edge((edge.split()[0], edge.split()[1])) edge = edges.readline() edges.close() print 'edges finished' print 'Drawing' # Draw as PNG dot = write(gr) gvv = gv.readstring(dot) gv.layout(gvv,'dot') gv.render(gvv,'svg','graph.svg') and it crashes at the gv.layout() call. The files are somthing like: nodes: node1 node2 node3 edges_ok: node1 node2 node2 node3

• C - floating point rounding

  - by hatorade

  I'm trying to understand how floating point numbers work. I think I'd like to test out what I know / need to learn by evaluating the following: I would like to find the smallest x such that x + 1 = x, where x is a floating point number. As I understand it, this would happen in the case where x is large enough so that x + 1 is closer to x than the next number higher than x representable by floating point. So intuitively it seems it would be the case where I don't have enough digits in the significand. Would this number x then be the number where the significand is all 1's. But then I can't seem to figure out what the exponent would have to be. Obviously it would have to be big (relative to 10^0, anyway).

• Who pays developers of open-source software?

  - by darko petreski

  We are facing a lot of open source software. But someone needs to write that software. How are they payed? Do you know a good article about the open source politics and economy? Sometimes the big companies themselves release open source because they have some benefits. Then they sell support, advices ... My question is what is the real economy about open software? No professional will work for nothing. This software are couple of classes but thousand or may be millions of classes. If you are really a pro you will write software for money, because you have life, wife, kids, taxes, you must earn. Please do not tell me that they are doing this for pleasure or hobby!

• How can I calculate data for a boxplot (quartiles, median) in a Ralis app on Heroku? ( Heroku uses P

  - by hadees

  I'm trying to calculate the data needed to generate a box plot which means I need to figure out the 1st and 3rd Quartiles along with the median. I have found some solutions for doing it in Postgresql however they seem to depend on either PL/Python or PL/R which it seems like Heroku does not have either enabled for their postgresql databases. In fact I ran "select lanname from pg_language;" and only got back "internal". I also found some code to do it in pure ruby but that seems somewhat inefficient to me. I'm rather new to Box Plots, Postgresql, and Ruby on Rails so I'm open to suggestions on how I should handle this. There is a possibility to have a lot of data which is why I'm concerned with performance however if the solution ends up being too complex I may just do it in ruby and if my application gets big enough to warrant it get my own Postgresql I can host somewhere else. *note: since I was only able to post one link, cause I'm new, I decided to share a pastie with some relevant information

• Quartz2d vector images vs OpenGL vector description?

  - by tbarbe

  How big of a difference is the description language of Quartz2d to OpenGL ES? It seems they are similar in description power... except that Quartz is mostly 2d and that OpenGL is out of the box 3d ( but can be made 2d focused ). Are the mappings from 2dQuartz to 2d OpenGL ES that different? Im sure there must be differences in some specific features that might be handled differently on one vs another... but to do a translator? Anyone have experience with both OpenGL and Quartz2d have some insights?

• How to: WCF XML-RPC client?

  - by mr.b

  I have built my own little custom XML-RPC server, and since I'd like to keep things simple, on both server and client side, what I would like to accomplish is to create a simplest possible client (in C# preferably) using WCF. Let's say that Contract for service exposed via XML-RPC is as follows: [ServiceContract] public interface IContract { [OperationContract(Action="Ping")] string Ping(); // server returns back string "Pong" [OperationContract(Action="Echo")] string Echo(string message); // server echoes back whatever message is } So, there are two example methods, one without any arguments, and another with simple string argument, both returning strings (just for sake of example). Service is exposed via http. Aaand, what's next? :) P.S. I have tried googling around for samples and similar, but all that I could come up with are some blog-related samples that use existing (and very big/numerous) classes, which implement appropriate IContract (or IBlogger) interfaces, so that most of what I am interested is hidden below several layers of abstraction...

  I'm doing some research, and looking to create a simple on-line business card creator. I need to give users the ability to pick a business card template and then update the text with their own information. Then I need to create a PDF proof for the user to sign off on, as well as create a hi-rez pdf for print. Can anyone point me in the right direction? I'm trying to find some resources on how to create the PDF Heres a quick example I found of what I'm trying to do. https://www.staplescopyandprint.ca/PrintOnline/InputFields.aspx?type=PersonalCard Any input at this point would be a big help thanks!

• Creating method templates in Eclipse

  - by stevebot

  Is there any way to do the following in eclipse? Have eclipse template a method like the following public void test(){ // CREATE MOCKS // CREATE EXPECTATIONS // REPLAY MOCKS // VERIFY MOCKS } so then I could presumably just use intellisense and select an option like "createtest" and have it stub out a method with the comments similar to the above?My problem is that often myself and other developers I know forgot all the steps we need to follow to do what we dub as a valid unit test for our application. If I could template our test methods to stub out the comments above it would be a big help.

• Weird behavior of std::vector

  - by Nima

  I have a class like this: class OBJ{...}; class A { public: vector<OBJ> v; A(int SZ){v.clear(); v.reserve(SZ);} }; A *a = new A(123); OBJ something; a->v.push_back(something); This is a simplified version of my code. The problem is in debug mode it works perfect. But in release mode it crashes at "push_back" line. (with all optimization flags OFF) I debugged it in release mode and the problem is in the constructor of A. the size of the vector is something really big with dummy values and when I clear it, it doesn't change... Do you know why? Thanks,

• Critiquing my first Python script

  - by tipu

  A little bit of background: I'm building an inverted index for a search engine. I was originally using PHP, but because of the amount of times I needed to write to disk, I wanted to make a threaded indexer. There's a problem with that because PHP is not thread safe. I then tried Java, but I ended up with at least 20 try catch blocks because of the JSON data structure I was using and working with files. The code was just too big and ugly. Then I figured I should pick up some Python because it's flexible like PHP but also thread safe. Though I'm open to all criticism, what I'd like to learn is the shortcuts that the Python language/library provides that I skipped over. This is a PHP-afide Python script because all I really did was translate the PHP script line by line to what I thought was it's Python equivalent. Thanks. http://pastebin.com/xrg7rf9w

• Can I get a dump of all my databases *except one* using mysqldump?

  - by Daniel Magliola

  I'm currently using mySQLdump to backup my dev machine and servers. There is one project I just started, however, that has a HUUUUUGE database that I don't really need backed up, and i'll be a big problem to add it to the rest of the backup cycle. I'm currently doing this: "c:\Program Files\mysql\MySQL Server 5.1\bin\mysqldump" -u root -pxxxxxx --all-databases g:\backups\MySQL\mysqlbackup.sql Is it possible to somehow specify "except this database(s)"? I wouldn't like to have to specify the list of DBs manually, since that would mean that I'd have to remember updating my backup batch file every time I create a new DB, and I know that's not gonna happen. EDIT: As you probably guessed from my command line above, i'm doing this on Windows, so I can't do any kind of fancy bash stuff, only wimpy .bat things. Alternatively, if you have other ideas to solve this same issue, they are more than welcome, of course! Thanks Daniel

• LINQ to SQL Web Application Best Practices

  - by derek

  In my experience building web applications, I've always used a n-tier approach. A DAL that gets data from the db and populates the objects, and BLL that gets objects from the DAL and performs any business logic required on them, and the website that gets it's display data from the BLL. I've recently started learning LINQ, and most of the examples show the queries occurring right from the Web Application code-behinds(it's possible that I've only seen overly simplified examples). In the n-tier architectures, this was always seen as a big no-no. I'm a bit unsure of how to architect a new Web Application. I've been using the Server Explorer and dbml designer in VS2008 to create the dbml and object relationships. It seems a little unclear to me if the dbml would be considered the DAL layer, if the website should call methods within a BLL, which then would do the LINQ queries, etc. What are some general architecture best practices, or approaches to creating a Web Application solution using LINQ to SQL?

• Are Symphony and CakePHP too slow to be usable?

  - by Aziz Light

  Until now, I have always said that CakePHP is too bloated and slow. I don't really know that, I just saw "some" benchmarks. What I really want to know, is that if those two frameworks (Symfony and CakePHP) are too slow to be usable in a way that the user will get frustrated. I already know that those frameworks are slower than other alternatives, but that's not the question. I ask the question because I want to create a project management web application and I still hesitate between a couple frameworks. I've had some trouble learning Zend, but imho I haven't tried hard enough. So in conclusion, in addition to the first question above, I would like to ask another question: If I want to create a project management tool (which is a pretty big project), which of the following should you suggest, considering the developement time, the speed of the resulting application, and the robustness of the final product: Symphony CakePHP Zend Framework Also I should mention that I don't know any of those frameworks, and that I want to learn one of them (at least).

• Quick backup system for large projects

  - by kamziro

  I've always backed up all my source codes into .zip files and put it in my usb drive and uploaded to my server somewhere else in the world.. however I only do this once every two weeks, because my project is a little big. Right now my project directories (I have a few of them) contains a hierarchy of c++ files in it, and interspersed with them are .o files which would make backing up take a while if not ignored. What tools exist out there that will let me just back things up efficiently, conveniently and lets me specify which file types to back up (lots of .png, .jpg and some text types in there), and which directories to be ignored (esp. the build dirs)? Or is there any ingenious methods out there that people use?

• How to implement "circular side-scrolling" in my game?

  - by Mr.Gando

  I'm developing a game, a big part of this game, is about scrolling a "circular" background ( the right end of the Background Image can connect with the left start of the Background image ). Should be something like this: ( Entity moving and arrow to show where the background should start to repeat ) This happens in order to allow to have an Entity walking, and the background repeating itself over and over again. I'm not working with tile-maps, the background is a simple Texture (400x300 px). Could anyone point me to a link , or tell me the best way I could accomplish this ? Thanks a lot.

• Detecting that the stack is full in C/C++

  - by Martin Kristiansen

  When writing C++ code I've learned that using the stack to store memory is a good idea. But recently I ran into a problem: I had an experiment that had code that looked like this: void fun(unsigned int N) { float data_1[N*N]; float data_2[N*N]; /* Do magic */ } The code exploted with a seqmentation fault at random, and I had no idea why. It turned out that problem was that I was trying to store things that were to big on my stack, is there a way of detecting this? Or at least detecting that it has gone wrong?

• Is their an optimal config/format for a TIFF when using Tesseract or other OCR?

  - by Zando

  I'm having a bizarre problem with Tesseract. I have a name, "Janice" that is in a 200x40 pixel tiff, that Tesseract interprets as a blank. I'm running hundreds of names through Tesseract and they are processed fine. What I'm actually doing, though, is breaking up a larger TIFF into smaller tiffs of one word each. In the larger TIFF, tesseract recognizes "Janice". What could cause it to hiccup in a TIFF that solely contains that word (and there's enough space around the word to not truncate any of the pixels)? I'm using ImageMagick to split the big TIFF, are there options I should set when reconstituting the new TIFF files?

• Discussion: Working TDD in a Scrum context

  - by Anders Juul

  Hi all, When I work TDD I tend to start out with the big picture and create the tests that should succeed in order for the overall assignment to be completed - it then kicks off a number of supporting classes/methods/tests as I 'dig in'. If my assignment has been planned out in detail, I would then open one task, and in order to solve it, open another and then another. Only when the overall tests are succeeding can I close the original task, which means that at any given time, I would have a number of open tasks. I find that this approach conflict somewhat with the scrum approach where, ideally, I should be able to take and close a task within a day's work - and never have more than one task open at a time. I'm looking for input about how you manage this in your project - references to articles are also very welcome, I'm sure this has been debated thoroughly somewhere... The 'answer tick' will be awarded to best comment/reference. Thanks for any input, Anders, Denmark

• Multithreading in Lua

  - by RCIX

  I was having a discussion with my friend the other day. I was saying how that, in pure Lua, you couldn't build a preemptive multitasking system. He claims you can, because of the following reason: Both C and Lua have no inbuilt threading libraries [OP's note: well, Lua technically does, but AFAIK it's not useful for our purposes]. Windows, which is written in mostly C(++) has pre-emptive multitasking, which they built from scratch. Therefore, you should be able to do the same in Lua. The big problem i see with that is that the main way preemptive multitasking works (to my knowledge) is that it generates regular interrupts which the manager uses to get control and determine what code it should be working on next. I also don't think Lua has any facility that can do that. My question is: is it possible to write a pure-Lua library that allows people to have pre-emptive multitasking?
