Is there a way to pause a CABasicAnimation?

- by mclaughlinj

I have a basic spinning animation of the iPhone. Is there any way that I can "pause" the animation so that the position of the view will be maintained? I guess one way of doing this would be to cause the animation to "complete" instead of calling "remove" on it, how would I do that? CABasicAnimation* rotationAnimation; rotationAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"]; rotationAnimation.toValue = [NSNumber numberWithFloat: M_PI * 2]; rotationAnimation.duration = 100; rotationAnimation.cumulative = YES; rotationAnimation.repeatCount = HUGE_VALF; rotationAnimation.removedOnCompletion = NO; rotationAnimation.fillMode = kCAFillModeForwards; [myView.layer addAnimation:rotationAnimation forKey:@"rotationAnimation"];

Do you know a good and efficient FFT?

- by yan bellavance

Hi, I am trying to find a very fast and efficient Fourier transform (FFT). Does anyone know of any good ones. I need to run it on the iPhone so it must not be intensive. Instead, maybe you know of one that is wavelet like, i need frequency resolution but only a narrow band (vocal audio range up to 10khz max...even 10Khz might be too high). Im thinking also of truncating this FFT to keep the frequency resolution while eliminating the unwanted frequency band. This is for an iphone ...I have taken a look at the FFT in Aurio touch but it seems this is an int FFT but my app uses floats.....would it give a big performance increase to try and adapt program to an int FFT or not(which i really dont feel like doing...plus aurio touch uses a radix 2 FFT which is not that great).

Polygon area calculation using Latitude and Longitude generated from Cartesian space and a world fil

- by Heath

Given a series of GPS coordinate pairs, I need to calculate the area of a polygon (n-gon). This is relatively small (not larger than 50,000 sqft). The geocodes are created by applying an affine transform with data from a world file. I have tried to use a two step approach by doing converting the geocodes to cartesian coordinates: double xPos = (lon-lonAnchor)*( Math.toRadians( 6378137 ) )*Math.cos( latAnchor ); double yPos = (lat-latAnchor)*( Math.toRadians( 6378137 ) ); then I use a cross product calculation to determine the area. The issue is that the results are a bit off in accuracy (around 1%). Is there anything I can look into to improve this? Thanks.

Read line comments in INI file

- by Dave Jarvis

The parse_ini_file function removes comments in configuration files. What would you do to keep the comments that are associated with the next line? For example: [email] ; Verify that the email's domain has a mail exchange (MX) record. validate_domain = true Am thinking of using X(HT)ML and XSLT to transform the content into an INI file (so that the documentation and options can be single sourced). For example: <h1>email</h1> <p>Verify that the email's domain has a mail exchange (MX) record.</p> <dl> <dt>validate_domain</dt> <dd>true</dd> </dl> Any other ideas?

Windows Store App Visual Basic Rotate Object with code

- by Ajay Raghav

How to rotate an ellipse (or any other object) with VB code? In XAML, I designed an ellipse and easily rotated it from the properties (Transform - Rotate - Angle). When I am trying to do it with VB code, I cannot locate the rotate/angle property of that ellipse. So, I tried this: Dim Rotator As RotateTransform Rotator.Angle = 90 Ellipse1.RenderTransform = Rotator It didn’t work. It says: Unable to cast object of type 'Windows.UI.Xaml.Media.MatrixTransform' to type 'Windows.UI.Xaml.Media.RotateTransform'. I think I’m close to the right way. Please give me a push. Thanks

Need a mysql query to extract data from mm-forms

- by Kirill

http://cl.ly/201a11b430bf60ef9e97 is what the rows look like, after I clean them up a bit: SELECT fk_form_joiner_id,form_key,value FROM wp_contactform_submit_data WHERE form_key!='page_post_id' AND form_key!='captcha-802' AND form_key!='page_post_title' AND form_key!='user_ID' What I need is a query where it would transform this into a structure like: id | First-name | Surname-name | your-email | dob | address-1 | address-2 | county | postcode | phone ------------------------------------------------------------------------------------------------------- 88 | jack | Somethin | [email protected] | dob | (etc) I think I know a way to do this through php, but I think there must be a way to do it as a mysql query. Ultimately, I need to export this (into a csv), but if you could give me a query that would output this into a mysql table (or at least a workable select query, that I could then turn into an insert query loop, to create a table), I'd do it form there. Thank you.

JSON to Persistent Data Store (CoreData, etc.)

- by Bryan Veloso

All of the data on my application is pulled through an API via JSON. The nature of a good percentage of this data is that it doesn't change very often. So to go and make JSON requests to get a list of data that doesn't change much didn't seem all that appealing. I'm looking for the most sensible option to have this JSON saved onto the iPhone in some sort of persistent data store. Obviously one plus of persisting the data would be to provide it when the phone can't access the API. I've looked at a few examples of having JSON and CoreData interact, for example, but it seems that they only describe transforming NSManagedObjects into JSON. If I can transform JSON into CoreData, my only problem would be being able to change that data when the data from the API does change. (Or, maybe this is all just silly.)

Transforming a string to a valid PDO_MYSQL DSN

- by Alix Axel

What is the most concise way to transform a string in the following format: mysql:[/[/]][user[:pass]@]host[:port]/db[/] Into a usuable PDO connection/instance (using the PDO_MYSQL DSN), some possible examples: $conn = new PDO('mysql:host=host;dbname=db'); $conn = new PDO('mysql:host=host;port=3307;dbname=db'); $conn = new PDO('mysql:host=host;port=3307;dbname=db', 'user'); $conn = new PDO('mysql:host=host;port=3307;dbname=db', 'user', 'pass'); I've been trying some regular expressions (preg_[match|split|replace]) but they either don't work or are too complex, my gut tells me this is not the way to go but nothing else comes to my mind. Any suggestions?

But if i leave it, doesnt work. Im using the following code to mix xml and xslt: XslCompiledTransform transformer = new XslCompiledTransform(); transformer.Load(HttpContext.Current.Server.MapPath("xslt\\searchresults.xslt")); transformer.Transform(xmlreader, null, utf8stringwriter); What im doing wrong? How could i mix xml and xslt if the xml has the xmlns attribute on top? Thanks in advance. Best Regards. Jose

How to GetGuiResources for all system processes?

- by Krzysztof

Hello, I need to measure all used GDI objects in a Windows xp system. I found a GetGuiResources(__in HANDLE hProcess, __in DWORD uiFlags) method (with the GR_GDIOBJECTS flag). I call it for the process which I get from the method GetCurrentProcess() defined in WinBase.h. I don't know how to call it for other system processes, which I get by System::Diagnostics::Process::GetProcesses(), because that function returns an array of Process pointers, and GetGuiResources takes a HANDLE. Does anybody know a solution for that? How can I transform Process pointer to a Handle or get HANDLEs for all running system processes? thanks for help in advance!

Storing links to internal content pages in ASP.NET MVC

- by mare

I'm using a route like this routes.MapRoute( "PageBySlug", RouteType.Regular, "{slug}", new {controller = "Page", action = "Display", slug = "Default"}, null ); to map request to ~/Some-Page-Slug to ~/Page/Display/Some-Page-Slug. When adding content, user can choose to link to existing pages to create references and I then store those links in this format in the datastore: "/Some-Page-Slug". When I run the app in Cassini and pull the link out from datastore and attach it to A tag it looks like this http://localhost:93229/Some-Page-Slug and this link works. But when running the application in virtual directory under some website in IIS, the attached link generates this URL http://localhost/Some-Page-Slug, when it should be http://localhost/virtualdir/Some-Page-Slug. Of course, this generates 404 error. How can I solve this to be universally useful and working under all circumstances? Should I store it differently in the database or should I transform it into correct form in my Views at runtime and how to do that?

Using EXSLT dates-and-times module in XSLT 1.0 yields unknown error

- by danielle

I added the EXSLT dates-and-times module in my XSLT 1.0 file by declaring: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" ... xmlns:date="http://exslt.org/dates-and-times" extension-element-prefixes="date"> This doesn't affect my resulting page, but when I try to call the actual date with: <xsl:value-of select="date:date-time()"/> I receive an "Error loading stylesheet: An unknown error has occurred ()" message when loading my page. Does anyone have a suggestion as to what I might be missing? Thanks in advance!

Implementing "Generator" support in a custom language

- by Roger Alsing

I've got a bit of fettish for language design and I'm currently playing around with my own hobby language. (http://rogeralsing.com/2010/04/14/playing-with-plastic/) One thing that really makes my mind bleed is "generators" and the "yield" keyword. I know C# uses AST transformation to transform enumerator methods into statemachines. But how does it work in other languages? Is there any way to get generator support in a language w/o AST transformation? e.g. Does languages like Python or Ruby resort to AST transformations to solve this to? (The question is how generators are implemented under the hood in different languages, not how to write a generator in one of them)

Using glRotate and glTranslate with collision detection.

- by Cetra

Hey guys, Say I use glRotate to translate the current view based on some arbitrary user input (i.e, if key left is pressed then rtri+=2.5f) glRotatef(rtri,0.0f,1.0f,0.0f); Then I draw the triangle in the rotated position: glBegin(GL_TRIANGLES); // Drawing Using Triangles glVertex3f( 0.0f, 1.0f, 0.0f); // Top glVertex3f(-1.0f,-1.0f, 0.0f); // Bottom Left glVertex3f( 1.0f,-1.0f, 0.0f); // Bottom Right glEnd(); // Finished Drawing The Triangle How do I get the resulting translated vertexes for use in collision detection? Or will I have to manually apply the transform myself and thus doubling up the work? The reason I ask is that I wouldn't mind implementing display lists.

Splitting string on probable English word boundaries

- by Sean

I recently used Adobe Acrobat Pro's OCR feature to process a Japanese kanji dictionary. The overall quality of the output is generally quite a bit better than I'd hoped, but word boundaries in the English portions of the text have often been lost. For example, here's one line from my file: softening;weakening(ofthemarket)8 CHANGE [transform] oneselfINTO,takethe form of; disguise oneself I could go around and insert the missing word boundaries everywhere, but this would be adding to what is already a substantial task. I'm hoping that there might exist software which can analyze text like this, where some of the words run together, and split the text on probable word boundaries. Is there such a package? I'm using Emacs, so it'd be extra-sweet if the package in question were already an Emacs package or could be readily integrated into Emacs, so that I could simply put my cursor on a line like the above and repeatedly invoke some command that splits the line on word boundaries in decreasing order of probable correctness.

GAE images.resize with fixed proportional crop

- by user288541

I need to resize and crop to exactly 60x80px from various size and aspect ratio. Just before i put into Datastore. Anyone already got this issue resolved. Currently i already succed to just transform it to exact height (80px) with various width which nott look so good when i try to display it on a list. e.g jcaroussel. My db.put code is like bellow: if users.get_current_user(): personal.personal_id = int(self.request.get('personal_id')) personal.name = self.request.get('name') personal.latitude = self.request.get('latitude') personal.info = self.request.get('info') photo = images.resize(self.request.get('img'), 0, 80) personal.photo = db.Blob(photo) personal.lc_id = int(self.request.get('lc_id')) personal.put() self.redirect('/admin/personal') else: self.response.out.write('I\'m sorry, you don\'t have permission to add this LP Personal Data.') I just want to do similar result when we upload our avatar on google talk/google chat. Anyone solved this? Thx

Google App Engine Python: get image upload size server-side

- by goggin13

I am building a Google App Engine App that lets users upload images; I have everything working fine, but I am struggling to find a way to ensure that the user does not upload an image too large (because I am resizing the images, so this crashes my python script). When a user uploads a large image, I get this error RequestTooLargeError: The request to API call images.Transform() was too large. I know that there is a size limitation on what GAE allows for it's image API, I am just trying to find a way to deal with this server side; something along the lines of if (image is too large): inform user else: proceed I haven't had any luck finding the right python code to do this; can anyone help me out?

Mysql-how to update the "domain.com" in "[email protected]"

- by w00t

Hi there, In my database I have a lot of users who've misspelled their e-mail address. This in turn causes my postfix to bounce a lot of mails when sending the newsletter. Forms include (but are not limited to) "yaho.com", "yahho .com" etc. Very annoying! So i have been trying to update those record to the correct value. After executing select email from users where email like '%@yaho%' and email not like '%yahoo%'; and getting the list, I'm stuck because I do not know how to update only the yaho part. I need the username to be left intact. So I thought I would just dump the database and use vim to replace, but I cannot escape the @ symbol.. BTW, how do I select all email addresses written in CAPS? select upper(email) from users; would just transform everything into CAPS, whereas I just needed to find out the already-written-in-CAPS mails.

For some reason when I try: echo urlize("test 23342"); I get "test-eiioe". Why is that and how can I fix it? Thank you very much!

Capturing a NSParseErrorException

- by Martin

Could someone tell me how I can capture a NSParseErrorException? The Situation: my app downloads a small .plist file. I convert this into dictionary using the string method -propertylist. This normally works fine. I check for a connection before going to retrieve the file, so it works fine if I've got a connection to the internet, and works fine when I don't. However, I discovered a use case that crashes. If I'm at location that requires authetication before connecting to the internet (at Starbucks, say) what's being returned by the app isn't a plist and the attempt to parse it causes the application to crash. So is there a way to transform my code so that the NSParseErrorException is caught and rather than crashing the program I can just skip over this piece of code? NSDictionary *temp = [myDownloadString propertyList]; I tried doing this if ([myDownloadString propertyList]==NSParseErrorException){ //do something } but that didn't work.

Draw a textured triangle (patch) in Matlab

- by Petter

I have a triangle in (u,v) coordinates in an image. I would like to draw this triangle at 3D coordinates (X,Y,Z) texture-mapped with the triangle in the image. Here, u,v,X,Y,Z are all vectors with three elements representing the three corners of the triangle. I have a very ugly, slow and insatisfactory solution in which I (1) extract a rectangular part of the image, (2) transform it to 3D space with the transformation defined by the three points, (3) draw it with surface, and (4) finally masking out everything that is not part of the triangle with AlphaData. Surely there must be an easier way of doing this?

Drag Rotate UIImageView by touch

- by rockstardev

I have an UIImageView that is a subview of an UIView. I'm trying to create a drag rotate effect with the UIImageView similar to spinning a bottle but I'm having trouble calculating the radians to rotate the image by. My code below seems like it should work because I've seen a similar calculation in Flash examples. Can anyone shed some light on what I'm doing wrong? Thanks. This is the code contained in my image view subclass: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; lastLocation = [touch locationInView:[self superview]]; } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; CGPoint location = [touch locationInView:[self superview]]; CGFloat xDisplacement = location.x - lastLocation.x; CGFloat yDisplacement = location.y - lastLocation.y; CGFloat rad = atan2f(yDisplacement,xDisplacement); self.transform = CGAffineTransformMakeRotation(rad); }

DTO and mapper generation from Domain Objects

- by Nicolas

I have plenty of java domain objects that I need to transform to DTOs. Please, don't start with the anti-pattern thing, the Domain Objects are what they are because of a long history, and I can't modify them (or not too much, see below). So, of course, we've passed the age of doing all that manually. I've looked around, and dozer seems the framework of choice for DTO mapping. But... what I'd really like is this: annotate classes and fields that I want in DTO, and run a tool that would generate the DTOs and the mappers. Does that sound too unreasonable? Does such a tool already exist?
