• Ensuring all git commits make it back to CVS when using git-cvs

  - by Eric

  I'm using git-cvs, and my general workflow is something like this: ...write some code... $ git commit $ git cvsexportcommit -c -p -v <asdf> $ git cvs-import $CVSROOT $ git pull This generally works fine for pushing my commits back to the CVS server and keeping things in sync. However, I'm wondering how I will realize that something is missing if I happen to do the "git commit" but forget to export it to the CVS server. Is there a reasonable way to get a diff between my git repository and the CVS server, so I would know that something hadn't been committed all the way through? Or perhaps there's a better method of doing this altogether?

• Article search engine in php

  - by Jason

  Hello, I am using sphinx as a search engine on my website its working perfect and I have no complain with it. The only thing it lacks is, it does not allow me to search articles whose query length is more than 15 words. I know in reality people don't use more than 3-4 words i want to use it for finding duplicate contents. I was wondering if there is any alternative solution to sphinx. I want to cope with duplicate contents. My main articles table is in innodb but I am also caching articles into MyISAM table as well for full text searching but when I search an article it takes ages to perform one search. Its not the query problem, i think mysql lacks the fulltext searching facility. Thanks Jason

• PHP - Foreach in a foreach + CodeIgniter

  - by Sebhael

  I got an image upload function working, but there's 4 images required in this image. And my current function is simply just overwriting the image despite the number. I'm wondering how I would insert (preferably) a letter into my foreach function. $uploads = array($this->uploads->data()); foreach ( $uploads as $key[] => $value ) { $imagename = $cleaned . '-s' . $value['file_ext']; //outputs clean-name-s.ext } By the time all is said and done, 4 images will require this function. Leaving me with clean-name-sa.ext, clean-name-sb.ext, clean-name-sc.ext, and clean-name-sd.ext (numbers work as well). The form does require that all 4 fields are filled out before submission, so would I just create an array of my desired identifiers and create a foreach loop that outputs 4 different $imagenames? Or is there a simpler, more logical approach to this.

• Angle between two 2d vectors, diff between two methods?

  - by Sean Ochoa

  Hey all. I've got this code snippet, and I'm wondering why the results of the first method differ from the results of the second method, given the same input? public double AngleBetween_1(vector a, vector b) { var dotProd = a.Dot(b); var lenProd = a.Len*b.Len; var divOperation = dotProd/lenProd; return Math.Acos(divOperation) * (180.0 / Math.PI); } public double AngleBetween_2(vector a, vector b) { var dotProd = a.Dot(b); var lenProd = a.Len*b.Len; var divOperation = dotProd/lenProd; return (1/Math.Cos(divOperation)) * (180.0 / Math.PI); }

• Eventlet client-server

  - by johannix

  I'm trying to setup a server-client interraction: Server gets a string from client Server returns data to client I got this working with socket.send and socket.recv, but was wondering how to get it working with files through socket.makefile. I've got most of the pieces working, but don't know how to force each of the pieces to read at the appropriate time. So what it looks like is happening is that both the client and server are reading on the socket at the same time. Any ideas on how to let the server complete the original read before the client starts waiting for its information? Below are the core pieces that reproduce the read lock. Server: def handle(green_socket): file_handler = green_socket.makefile('rw') print 'before server read' lines = file_handler.readlines() print "readlines: %s" % (lines) print '** Server started **' server = eventlet.listen((HOST, PORT)) pool = eventlet.GreenPool() while True: new_sock, address = server.accept() pool.spawn_n(handle, new_sock) Client: from eventlet.green import socket green_socket = eventlet.connect((HOST, PORT)) file_handler = green_socket.makefile('rw') print 'before write' file_handler.writelines('client message') file_handler.flush() print 'before client read' lines = file_handler.readlines()

• Make a service monitor and restart process

  - by Andrej

  Hi, i'm making an app that needs to be up and running at all times. (24/7) I'm not very expirienced with services, but I read on the internet that services can be made uncolasble by setting their "onclose" property to false. I have got the service monitoring my app, and the service can't be closed directly from the task manager services window... but, when I click "go to process" task manager leads me to the process the service spawned. From there I can close the process and instantly close the service. Since I don't have much expirience with services i'm wondering, is this behavior normal? If not, how to make the service unstopable?

• FlowDocument contents as text

  - by tyndall

  What is the best way to get back the XAML/XML value of a FlowDocument? I noticed there isn't a .Value, .Text, .Caption, .ToXml(), etc... UDPATE: I'd like to be able to get access to it initially to serialize to disk or database. Treat it as its own document format. Later translating it to other formats would be nice. Also been wondering: Any equivalent to a hyperlink (opens in new browser window) in a FlowDocument? Any workaround?

• Splitting android application in to two 'branches', free and paid.

  - by Alxandr

  I've developed an android-application that I'dd like to put up on the marketplace. However, I want to split it into two separate applications, one free (with ads), and one paid (logically without ads). How would I go about doing that? I'm not wondering about adding ads (I've alreaddy managed that), but how to take one existing android-application (eclipse-project) and split it into two without having to create a new project and just copy-paste every file one by one (or in batch for that matter). Is that possible? Btw, I use GIT for SCM, so I've made two separate branches, one master and one free, but I need to set some cind of config-value that makes shure that the market separates them as two different applications. Also, when a user 'upgrades', is it possible to copy the db from the free app to the paid one?

• DotNetOpenAuth: Mock ClaimsResponse

  - by Pickels

  Hello, I was wondering how I can mock the ClaimseReponse class in DotNetOpenAuth? This is the class(remove a few properties): [Serializable] public sealed class ClaimsResponse : ExtensionBase, IClientScriptExtensionResponse, IExtensionMessage, IMessageWithEvents, IMessage { public static bool operator !=(ClaimsResponse one, ClaimsResponse other); public static bool operator ==(ClaimsResponse one, ClaimsResponse other); [MessagePart("email")] public string Email { get; set; } [MessagePart("fullname")] public string FullName { get; set; } public override bool Equals(object obj); public override int GetHashCode(); } This is what I tried: ClaimsResponse MockCR = new ClaimsResponse(); MockCR.Email = "[email protected]"; MockCR.FullName = "Mister T"; I get the following error: '...ClaimsResponse(string)' is inaccessible due to its protection level. Kind regards, Pickels

• Quick question on session security.

  - by Scarface

  Hey guys, I was scanning my site for security and I noticed that it was possible for non users to send requests and post information, so I decided to put login checks on all information posts. I was wondering if it was a good way to keep a session id that is created by md5(uniqid()); in a session variable $_SESSION['id']=md5(uniqid()); for each user and then store that in a database under active users for that user. Then when a user tries to insert information, verify that their $_SESSION['id'] variable is equal to the one in the database where the username equals their $_SESSION['username']. What are your ideas on this guys? Thanks in advance!

• How can I use the SSRS ReportViewer from VS 2008 in a VS2010 project?

  - by Adrian Grigore

  Hi, I'm working on an ASP.NET MVC 2 / .NET 3.5 project which includes SSRS 2008 reports. After migrating to VS 2010 RC, the new web forms report viewer has been giving so much trouble that I'd like to use the old report viewer from VS 2008 again. Now I'm just wondering what would be the easiest way to do that. The report viewer is embedded in a Webforms ASPX file which is loaded in an IFrame by the the MVC view. Report parameters are currently stored as session variables, and for security reasons I would prefer not to change that for HTTP POST or GET parameters. So I can't just put the report viewer in a separate application and build that with VS2008. Moving the entire project back to VS 2008 is not an option. So, what's the easiest way for me to use the VS 2008 ReportViewer in VS 2010? Is there way to grab an assembly from VS 2008 and use that in my project? Thanks, Adrian

• Override Javascript Function Based on Passed Parameters

  - by George

  Is it possible to override a function based on the number of parameters that you are passing into it? For instance: function abc(name) { document.write ('My name is' + name); } function abc(name,friend) { document.write ('My name is' + name + 'and my best friend\'s name is' + friend); } So in the HTML if I just called abc(george) it would use the first version of the function, but if I called abc(george,john) it would use the second version. There may be other ways to accomplish the example I used, but I'm just wondering if the concept is sound in javascript.

  - by Blaenk

  Now that the Unreal Development Kit is out and free to use by anyone, I am pretty excited to try it out. My understanding is that the programming is done through scripting in UnrealScript, I am wondering if any of you guys know of any good articles, tutorials, books, and references for Unreal Script or the Unreal Development Kit. Documentation UnrealScript Reference for Unreal Engine 3 UnrealScript at UnrealWiki Tools nFringe - Visual Studio Extension for UnrealScript Setting up an nFringe UDK project Tutorials Chimeric - Coding tutorials Video Tutorials 3D Buzz Video Tutorials Sorry if I screwed up on this. It's my first community wiki post, let me know if I did something wrong :)

• asp.net mvc controller actions testing

  - by Imran

  I was just wondering how others are going about testing controller actions in asp.net mvc? Most of my dependencies are injected in to my controllers so there is a not a huge amount of logic in the action methods but there may be some conditional logic for example which I think is unavoidable. In the past I have written tests for these action methods, mocked the dependencies and tested the results. I have found this is very brittle and a real PITA to maintain. Having 'Expect' and 'Stub' methods everywhere breaks very easily but I don't see any other way of testing controller actions. I actually think it might be easier to test some of these manually! Anyone have any suggestions? Perhaps I am missing something here? Thanks Imran

• Experience using Yii framework for actual PHP project

  - by desireco

  I've been using Code Igniter for my PHP projects, when I start them from the beginning. It is very nice framework, saves me a lot of work and let me have low level access if I need to do something special. Code Igniter is also faster then similar frameworks by order of magnitude. I came across Yii framework which claims to be even faster and easier and prettier and whatever. I never heard of it and I was wondering if someone used it in some real life project and have practical experience that he is willing to share.

• Best server-side javascript servers.

  - by fmsf

  Hey, I've been wondering to try out server-side javascript for a while. And I'm finding a good amount of servers, like: Node.js Rhino SpiderMonkey among others. Could anyone with experience on server-side javascript, tell me which are the best engines? and why? I like the Node.js because it's based on Google's V8 engine. And seems easy to use. But some feedback on what you would choose would be great. Edit: Some benchmarks for Node. I'm thinking on going with this one but feedback is still welcome. Thanks

• Outlets buggy, causing crash?

The implementation seems fine. @synthesize and the memory release functions were called properly.

• Windows batch file to delete .svn files and folders

  - by Marco Demaio

  Hi,in order to delete all ".svn" files/folders/subfolders in "myfolder" I use this simple line in a batch file: FOR /R myfolder %%X IN (.svn) DO (RD /S /Q "%%X") This works, but if there are no ".svn" files/folders the batch file shows a warning saying: "The system cannot find the file specified." This warning is very noisy so I was wondering how to make it understand that if it doesn't find any ".svn" files/folders he must skip the RD command. Usually using wild cards would suffice, but in this case I don't know how to use them, because I don't want to delete files/folders with .svn extension, but I want to delete the files/folders named exactly ".svn", so if I do this: FOR /R myfolder %%X IN (*.svn) DO (RD /S /Q "%%X") it would NOT delete files/folders named extaclty ".svn" anymore. I tried also this: FOR /R myfolder %%X IN (.sv*) DO (RD /S /Q "%%X") but it doesn't work either, he deletes nothing. Thanks for any help!

• Eclipse’s Ctrl+click does not work and indexer does not seem to update?

  - by bbazso

  I am running Eclipse IDE for C/C++ Developers (Ganymede) and I have recently encountered a problem with it. I can no longer get Ctrl+click navigation to work! I went to my project and tried to rebuild the index, but the rebuild command of the indexer does not work either. I did not do anything to my knowledge that may have caused this bug and so I was wondering if it could be a corrupt index or something else weird like that. Any help on this matter would be greatly appreciated. Thanks!

• SQL: Return "true" if list of records exists?

  - by User

  An alternative title might be: Check for existence of multiple rows? Using a combination of SQL and C# I want a method to return true if all products in a list exist in a table. If it can be done in all in SQL that would be preferable. I have written a method that returns whether a single productID exists using the following SQL: SELECT productID FROM Products WHERE ProductID = @productID If this returns a row, then the c# method returns true, false otherwise. Now I'm wondering if I have a list of product IDs (not a huge list mind you, normally under 20). How can I write a query that will return a row if all the product id's exist and no row if one or more product id's does not exist? (Maybe something involving "IN" like: SELECT * FROM Products WHERE ProductID IN (1, 10, 100))

• Creating a user-defined code generation system in PHP

  - by user270766

  My newest project that I'm looking to build with CodeIgniter would require some sort of system that would allow a user to drag and drop pre-defined functions/methods into mini-classes/objects and then run/test them in the browser. So it'd something similar to Scratch. I've designed a relational database that I think could work for this (storing the function names and have these classes "subscribe" to those functions) - but I'm wondering whether or not to go ahead with it. Is there a better way to do this or is there a system out there that would accomplish this for me? EDIT: It would have to be extremely simple for an end user, but hopefully be flexible enough to easily add more complex functionality in the future.

• What happens if my IExceptionPublisher throws an Exception?

  - by Graphain

  Hi, I'm using the .NET Exception Management Application Block (EMAB). As part of this I am implementing IExceptionPublisher classes. However, I am wondering what happens if these publishers encounter an Exception. I had a bit of a look around and apparently they are meant to do something like this: try { /* Normal Exception Publishing */ } catch { ExceptionManager.PublishInternalException(exception, additionalInfo); } Source: One caveat: what happens if there is an exception in our custom publisher code, preventing the publishing to MSMQ? For that, we turn to the ExceptionManager.PublishInternalException method, which will publish the exception to the default publisher, which is the Windows application event log. However, PublishInternalException is both protected and internal so I would have to be implementing ExceptionManager, not IExceptionPublisher, to access it.

• Covering Earth with Hexagonal Map Tiles

  - by carrier

  Many strategy games use hexagonal tiles. One of the main advantages is that the distance between the center of any tile and all its neighboring tiles is the same. I was wondering if anyone has any thoughts on marrying a hexagonal tile system with the traditional geographic system (longitude/latitude). I think it would be interesting to cover a globe with hexagonal tiles and be able to map a geographic coordinate to a tile. Has anyone seen anything remotely close to this before? UPDATE I'm looking for a way to subdivide the surface of a sphere so that each division has the same surface area. Ideally, the centers of adjacent sub-divisions would be equidistant.

• Sumproduct using Django's aggregation

  - by Matthew Rankin

  Question Is it possible using Django's aggregation capabilities to calculate a sumproduct? Background I am modeling an invoice, which can contain multiple items. The many-to-many relationship between the Invoice and Item models is handled through the InvoiceItem intermediary table. The total amount of the invoice—amount_invoiced—is calculated by summing the product of unit_price and quantity for each item on a given invoice. Below is the code that I'm currently using to accomplish this, but I was wondering if there is a better way to handle this using Django's aggregation capabilities. Current Code class Item(models.Model): item_num = models.SlugField(unique=True) description = models.CharField(blank=True, max_length=100) class InvoiceItem(models.Model): item = models.ForeignKey(Item) invoice = models.ForeignKey('Invoice') unit_price = models.DecimalField(max_digits=10, decimal_places=2) quantity = models.DecimalField(max_digits=10, decimal_places=4) class Invoice(models.Model): invoice_num = models.SlugField(max_length=25) invoice_items = models.ManyToManyField(Item,through='InvoiceItem') def _get_amount_invoiced(self): invoice_items = self.invoiceitem_set.all() amount_invoiced = 0 for invoice_item in invoice_items: amount_invoiced += (invoice_item.unit_price * invoice_item.quantity) return amount_invoiced amount_invoiced = property(_get_amount_invoiced)

• How to load font from InputStream in SWT?

  - by parxier

  I need to load font (.otf or .ttf) file from java Resource or InputStream in SWT. org.eclipse.swt.graphics.Device.loadFont(String path) allows me (example) to load font from font file path (and it works), but there is no corresponding method to load it from any other source. I was thinking of using java.awt.Font.createFont(int fontFormat, InputStream fontStream) and then building org.eclipse.swt.graphics.FontData and org.eclipse.swt.graphics.Font objects out of AWT java.awt.Font object. Since I haven't tried that option yet (I don't even know if it works that way) I was just wondering if there are any other options available?
