• friendly url in categories

  - by ntan

  Hi to all, i am trying to use friendly url for my categories. Example Database cat_id | parent_id | name | url 1 0 cat1 cat1 2 1 cat2 cat2 My approach to do is to pass the parameter cat with url value for example show.php?cat=cat1 and in .htaccess i must rewrite to /cat1 BUT what about when i want to access cat2. I want to rewrite as cat1/cat2 so the parameter is show.php?cat=cat1/cat2 and then parse the value to secure that cat2 belong to cat1. And so on. I am not using MVC so i have to do it on my own. Please if any other solutions is better please advice or suggest me reading Thank in advance.

• Using StructureMap, how do you explicitly trigger the reinstantiation of a object with InstanceScope

  - by Mark Rogers

  I have an integration test harness where I want to teardown and then re-instantiate some of the singleton-scoped objects I've registered with StructureMap, after and before each test. This way I can simulate the actual run time environment, but not have the singleton's state being passed from one test to another. Maybe this isn't a great way to do an integration test, but I'm running out of alternative solutions (read open to any advice). So can an object with InstanceScope.Singleton, be re-instantiated? What's the best way to do re-instantiate a singleton-scoped object with StructureMap?

• Custom Providers & Design Patterns

  - by Code Sherpa

  Hi. I am using ASP.NET 2.0 and its various providers. I have overridden most of the methods I need and have the following custom providers: ProjectMembershipProvider ProjectProfileProvider ProjectRoleProvider In the design of my project, my intention was to wrap the custom providers in a facade - style design - mixing and matching profiling, membership, and roles in API methods to simplify things for developers. But, I am finding that a lot of the methods in my custom providers don't need to change, really. And, it seems silly to wrap a stand-alone method in another method that does exactly the same thing. So - is my approach wrong? Or, should I allow end - users to instantiate the custom providers when needed and the mix/match api when needed? This seems a bit redundant to me but I can't see another way. Advice appreciated. Thanks.

• SwingWorker in Java (beginner question)

  - by Malachi

  I am relatively new to multi-threading and want to execute a background task using a Swingworker thread - the method that is called does not actually return anything but I would like to be notified when it has completed. The code I have so far doesn't appear to be working: private void crawl(ActionEvent evt) { try { SwingWorker<Void, Void> crawler = new SwingWorker<Void, Void>() { @Override protected Void doInBackground() throws Exception { Discoverer discover = new Discoverer(); discover.crawl(); return null; } @Override protected void done() { JOptionPane.showMessageDialog(jfThis, "Finished Crawling", "Success", JOptionPane.INFORMATION_MESSAGE); } }; crawler.execute(); } catch (Exception ex) { JOptionPane.showMessageDialog(this, ex.getMessage(), "Exception", JOptionPane.ERROR_MESSAGE); } } Any feedback/advice would be greatly appreciated as multi-threading is a big area of programming that I am weak in.

• shortest path search in a map represented as 2d shapes

  - by joe_shmoe

  Hi, I have a small library of a few shortest path search algorithms. They were developed for simple undirected graphs (the normal representation - vertices and edges). Now I'd like to somehow apply them on a bit different scenario - where the maps are represented as 2-dimensional shapes, connected by shared edges (edges of the polygons, that is). In this scenario, the search can start/end either at a map object or some point (x,y). What would be the best approach? Try to apply the algorithms onto shapes? or try to extract a 'normal' graph out of the shapes (I have preprocessing time available)? Any advice would be much appreciated, as I'm really not sure which way to go, and I don't have enough time (and skill) to explore many options... Thanks a lot

• Subversion and project management web based super tool. Like Team Foundation Server but not TFS.

  - by Rob Stevenson-Leggett

  Hi, We're currently looking at an IT upgrade and I'm after recommendations for a tool which can do some or all of the following. SVN management (authz, web viewer, commit log, diff) Create template projects (1 click e.g. create me a microsite with this name in svn and give these people access) Reporting on code churn, time spent on tasks on a per project basis User story management Basically like Team Foundation Server but that integrates with SVN properly (reason for this - we have a wide range of skill sets and not everyone can use a TFS client). Is there a combination of Trac plugins + something that can create trac instances (a la Dreamhost's admin panel) that can acheive this. On a side note, does anyone have any experience of version controlling designery type files - e.g. PSDs, Illustrator files. Any advice at all appreciated. Cheers, Rob

• Compact Framework : Read a SQL CE database on a PDA from a PC

  - by CF_Maintainer

  Hello, I have tasked with upgrading a CF Framework 1.1 suite of apps. Currently, the PC starts a server [after confirming via RAPI that the device exists and is connected] and spawns a app on the PDA as the client. The client process on the PDA talks with the db on the PDA and returns records to the PC app [using SQL CE 2.0. OpenNETCF 1.4 for communication/io]. I have a chance to upgrade the PC and PDA suite of apps to Framework 3.5 & CF 3.5 respectively. Due to a business requirement, I cannot get rid of workflow requiring the PC app to show a preview of the work done on the PDA. Question : Are there better ways to achieve the above in general with the constraints I have? I would really appreciate any Ideas/advice.

• Random access gzip stream

  - by jkff

  I'd like to be able to do random access into a gzipped file. I can afford to do some preprocessing on it (say, build some kind of index), provided that the result of the preprocessing is much smaller than the file itself. Any advice? My thoughts were: Hack on an existing gzip implementation and serialize its decompressor state every, say, 1 megabyte of compressed data. Then to do random access, deserialize the decompressor state and read from the megabyte boundary. This seems hard, especially since I'm working with Java and I couldn't find a pure-java gzip implementation :( Re-compress the file in chunks of 1Mb and do same as above. This has the disadvantage of doubling the required disk space. Write a simple parser of the gzip format that doesn't do any decompressing and only detects and indexes block boundaries (if there even are any blocks: I haven't yet read the gzip format description)

• Using axWebBrowser control to capture page request and postdata.

  - by Arjo

  I'm writing a small utility to capture all requests made to a web server from a windows application using the axWebBrowser control. So far I have the following working, as the user traverse the website clicking on links, posting forms etc I capture the webpage and the data being send to the server to request the next page. Where I run into a stumbling block is when it comes to Ajax calls. There are number of drop down boxes that filter down the selection as the user types in the search term, I would like to capture the page/script that is called and the data being send. Any hint, advice would be greatly appreciated.

• Whats the best way to stop this app crash when buttons rapidly pressed iphone obj-c

  - by dubbeat

  Hi, I'm not entirely sure why this crash is happening and I'd like to get advice on the best way to deal with it. My app has 3 buttons. Each button requests a different XML file from a server which is used to populate a table view. If I rapidly press the buttons in sequence , button 1 button 2 button3 button 1 button 2 button3 button 1 button 2 button3 the application quits. What could be causing this. Would id be in the NSURLRequest side of things or the table view population side? How would you suggest I stop this behaviour? I was going to just set a boolean "isRequesting" to true when a button is pressed and set it to false when the table view is finished populating. If any button is pressed while isRequesting is True they do nothing. Does that sound wise or is there a better way? Thanks, dub

• Numerical Pattern Matching

  - by Timothy Strimple

  A project I'm researching requires some numerical pattern matching. My searches haven't turned up many relevant hits since most results tend to be around text pattern matching. The idea is we'll have certain wave patterns we'll need to be watching for and trying to match incoming data vs the wave database we will be building. Here is and example of one of the wave patterns we'll need to be matching against. There is clearly a pattern there, but the peaks will not have the exact same values, but the overall shape of the wave iterations will be very similar. Does anyone have any advice on how to go about storing and later matching these patterns, and / or other search terms I can use to find more information on the subject of pattern matching? Thanks, Tim.

• Moderating computer-addiction through programming

  - by every_answer_gets_a_point

  i have an addiction to be on the computer all the time. it doesn't matter what i am doing as long as i am in front of it. i feel like the whole world is here and this is all that matters. i found that through some intellectual stimulation, like writing algorithms, it has helped me to be more satisfied with the time on the computer and i dont need it as much. if any of you have had experience with reliving your computer anxiety through writing code, can you tell me exactly what you wrote, and what you may recommend i work on? thank you for your programming advice

• Best ASP.NET reporting engine with custom reports creation ability

  - by Alex Konduforov

  We need to choose the reporting engine for our ASP.NET application. The main functional requirement is an ability for end users (not programmers, just normal users) to create custom reports. We will be using SQL Server as a database so I am aware of some options: SQL Server Reporting services, Crystal Reports, Active Reports, even WindwardReports. But frankly speaking I've never used any of those except Reporting services and it's quite difficult to choose which one suits the best to customer needs of custom reports creation. Is it possible to get some pros and cons for these options or at least your advice on what would be better to use in this case. Thanks a lot.

• nul terminating a int array

  - by robUK

  Hello, gcc 4.4.4 c89 I was just experimenting with a int array. And something just came to my mind. Can I nul terminate it. For example, I am using a 0 to nul terminate. However, 0 could well be a valid value in this array. The code below will terminate after the 5. Even though I mean 0 to be a valid number. However, I could specify the size of the array. But in this case, I don't want to this as I am just interested in this particular problem. Many thanks for any advice, #include <stdio.h> static void test(int *p); int main(void) { int arr[] = {30, 450, 14, 5, 0, 10, '\0'}; test(arr); return 0; } static void test(int *p) { while(*p) { printf("Array values [ %d ]\n", *p++); } }

• rails wiki site - article edit highlighting/strikethrough with htmldiff maxes cpu

  - by mark

  Hi I'm implementing a wiki style site and want to highlight changes made to articles between successive versions. Using htmldiff to highlight changes works great, except it is rather cpu intensive. I'm using the awesome vestal_versions plugin for versioning. So how best to handle this? I considered having an on_create callback on version creation create a delayed job that processes and then stores the htmldiff processed article (in the version table row). If this is a good approach, how can I extend vestal_versions without touching the gem? Or maybe there would be a better approach. Any advice is much appreciated. :)

• deploying vb.net app with database on server

  - by vbNewbie

  I have an application that accesses a sql server 2008 database. The server and database is stored on my local harddrive and I would like to learn to scale this up to having multiple users in our office access the application which I will i deploy on a server. For now the database will stay on my pc until I am ready to put it on a dedicated server for myself but for now how do I allow the application still to access my database. Here is my current connection string: <add key="ConnectionString" value="Data Source=.;Initial Catalog=SearchEngine;User ID=sa;Password=pss;Trusted_Connection=False;" /> Now I know how to deploy a general vb.net application but what I dont know is what to do with the database. Please help with any advice

• How do I delete a file from depot, but leave local copy in tact?

  - by Gary

  I'm trying to learn Perforce and want to delete a file from the depot(easy to do with p4 delete, p4 submit), but that deletes it from the client machine dir structure as well. I want to keep my local file in my directory intact. The only way I can see to do this would be to move it out of the hierarchy that is under Perforce control before deleting. I was able to get my file back by syncing an earlier version. Maybe I set up my client workspace wrong? Or am I misunderstanding a fundamental concept of source control? The client workspace is /home/user and I did it this way so I could add any file under my home directory without getting an error about the file not being under client's root. FYI - Linux client and server running P4D/LINUX26X86/2009.1/222893 (2009/11/12) Any advice appreciated. Thanks.

• How to structure class to support imported 3d model ?

  - by brainydexter

  Hello, I've written a C++ library that reads in this 3d model file (collada DAE). uptil now, I would output a list of triangles and handle each at rendering stage. But now, I need to attach some Bounding sphere information with the imported model. I need some advice on how should I organize this in code. Here are some specs of the 3D file format: - 3D model is represented as a Tree consisting of nodes - each node can contain other nodes, geometry information, transformation etc My requirements: - a bounding sphere associated with each node, thereby yielding a tree of bounding sphere hierarchy for the model itself. - actual vertex information What would be the recommended way to deal with this situation? Thanks

• Block until an event has completed.

  - by robUK

  Hello, gcc 4.4.2 c89 I have a function that has to run (config_relays). It make a call to a API function called set_relay, then the code has to wait before continuing until the event for set_relay event has completed. The set_relay is any Async call. i.e. void run_processes() { switch() { case EV_RELAY_SET: break; } } void config_relays() { set_relay(); /* Wait until EV_RELAY_SET has fired */ /* Cannot do init_relay until set_relay event has fired - has to block here */ init_relay(); } I guess I could put the init_relay() in the switch. However, that event is used for other things and not just for initializing the relay. I would really like to handle everything in the config_relays function. In C# you can do this by using autoreset. Does C have anything like that. Many thanks for any advice,

• Access block level storage via kernel

  - by N 1.1

  How to access block level storage via the kernel (w/o using scsi libraries)? My intent is to implement a block level storage protocol over network for learning purpose, almost the same way SCSI works. Requests will be generated by initiator and sent to target (both userspace program) which makes call to kernel module and returns the data using TCP protocol to initiator. So far, I have managed to build a simple "Hello" module and run it (I am new at kernel programming), but unable to proceed with block access. After searching a lot, I found struct buffer_head * bread(int dev,int block) in linux/fs.h, but the compiler throws error. error: implicit declaration of function ‘bread’ Please help, also feel free to advice on starting with kernel programming. Thank you!

• How can I learn the math necessary for working with computer vision?

  - by Duncan Benoit

  I know that computer vision involves a lot of math, but I need some tips about how programmers gain that knowledge. I've started to use the OpenCV library but I have some major problems in understanding how the math works in the algorithms. In college I have studied some math and we worked with matrices and derivatives, but I didn't pay to much attention to the subject. It seemed to be so difficult and useless from a programmer point of view. I suppose that there has to be some easy way to understand what a second derivative is without calculating an equation. (Derivatives are just an example) Do you have any tips for me about how can i gain such knowledge? A forum, book, link, advice, anything?

• difference in logging mechanism: API and application(python)

  - by zubin71

  I am currently writing an API and an application which uses the API. I have gotten suggestions from people stating that I should perform logging using handlers in the application and use a "logger" object for logging from the API. In light of the advice I received above, is the following implementation correct? class test: def __init__(self, verbose): self.logger = logging.getLogger("test") self.logger.setLevel(verbose) def do_something(self): # do something self.logger.log("something") # by doing this i get the error message "No handlers could be found for logger "test" The implementation i had in mind was as follows: #!/usr/bin/python """ .... .... create a logger with a handler .... .... """ myobject = test() try: myobject.do_something() except SomeError: logger.log("cant do something") Id like to get my basics strong, id be grateful for any help and suggestions for code you might recommend I look up. Thnkx!
