• Can I programatically determine if a PNG is animated?

  - by alex

  I have PNG (as well as JPEG) images uploaded to my site. They should be static (i.e. one frame). There is such thing as APNG. (it will be animated in Firefox). According to the Wikipedia article... APNG hides the subsequent frames in PNG ancillary chunks in such a way that APNG-unaware applications would ignore them, but there are otherwise no changes to the format to allow software to distinguish between animated and non-animated images. Does this mean it is impossible to determine if a PNG is animated with code? If it is possible, can you please point me in the right direction PHP wise (GD, ImageMagick)?

• I have a bunch of divs floated left, lined up in columns with different heights. They dont create a

  - by Roeland

  Hey guys, I am trying to create a grid like system with div's with content floated left. The problem is that the height of each div is not static since the content is different in each one. Since the height is different.. things get outta whack if one is taller then another in one row. Is there some sort of css way or js (prefer javascript) way to get around this. I really want to avoid setting large heights on the divs to get them to line up. You can see the example here: http://www.foreclosurejournalinc.com/index.php?option=com_hotproperty&view=type&id=1

• Java Convert ColorSpace of BufferedImage to CS_GRAY without using ConvertColorOp

  - by gmatt

  I know its possible to convert an image to CS_GRAY using public static BufferedImage getGrayBufferedImage(BufferedImage image) { BufferedImageOp op = new ColorConvertOp(ColorSpace .getInstance(ColorSpace.CS_GRAY), null); BufferedImage sourceImgGray = op.filter(image, null); return sourceImgGray; } however, this is a chokepoint of my entire program. I need to do this often, on 800x600 pixel images and takes about 200-300ms for this operation to complete, on average. I know I can do this alot faster by using one for loop to loop through the image data and set it right away. The code above on the other hand constructs a brand new 800x600 BufferedImage that is gray scale. I would rather just transform the image I pass in. Does any one know how to do this with a for loop and given that the image is RGB color space?

• WPF window scrolling with top menu

  - by Greg R

  I'm running into a dilemma. When I make the ScrollViewer the main content object of my window, scrolling behaves exactly like I want it to. You resize to make it smaller than the content and the window and scroll bars appear. The problem comes in when I want the to menu to be static and the rest of content to be scrollable. I want the scroll bars to behave the same way as a browser window does, meaning when you resize it, the scroll bars appear based on the size of the content. When you expand the window, the content takes up the entire real estate of the window. Is that possible in WPF? Help would be GREATLY appreciated.

• Jquery UI Dialog Weird Behavior in Firefox - Whole screen becomes non-clickable on second overlay

  - by Dondon Vizcayno

  I have two links that show up two modal dialogs. These dialogs are static divs in the html of the page with their own ids. When I click the first link, the first dialog shows up and behaves correctly. But when I click the second link, the whole screen grays out and everything becomes unclickable, including the second dialog. It happens also the other way around, clicking the second link, and then the first link. This problems occurs only in Firefox but not in IE. Any ideas why this is happening in Firefox?

• C# implicit conversions

  - by Chris Boden

  Hello, I'm currently working on an application where I need to load data from an SQL database and then assign the retrieved values into the properties of an object. I'm doing this by using reflection since the property names and column names are the same. However, many of the properties are using a custom struct type that is basically a currency wrapper for the decimal type. I have defined an implicit conversion in my struct: public static implicit operator Currency(decimal d) { return new Currency(d); } This works fine when I use it in code. However, when I have this: foreach (PropertyInfo p in props) { p.SetValue(this, table.Rows[0][p.Name], null); } It throws an ArgumentException stating that it cannot convert from System.Decimal to Currency. I'm confused since it works fine in any other circumstance.

• logging in scala

  - by IttayD

  In Java, the standard idiom for logging is to create a static variable for a logger object and use that in the various methods. In Scala, it looks like the idiom is to create a Logging trait with a logger member and mixin the trait in concrete classes. This means that each time an object is created it calls the logging framework to get a logger and also the object is bigger due to the additional reference. Is there an alternative that allows the ease of use of "with Logging" while still using a per-class logger instance? EDIT: My question is not about how one can write a logging framework in Scala, but rather how to use an existing one (log4j) without incurring an overhead of performance (getting a reference for each instance) or code complexity. Also, yes, I want to use log4j, simply because I'll use 3rd party libraries written in Java that are likely to use log4j.

• Are there any other Java schedulers besides Quartz(FOSS) and Flux(Commercial)

  - by mP

  I am interested in finding out about other job scheduling packages besides Quartz and Flux. Given the plethora of web frameworks i find it perculiar that there is really only one scheduler. Are there others that perhaps are very much unknown/unpopular ? Spring Batch Not really a scheduling solution but rather a batch job coordinator etc. http://static.springsource.org/spring-batch/faq.html#schedulers How does Spring Batch differ from Quartz? Is there a place for them both in a solution? Spring Batch and Quartz have different goals. Spring Batch provides functionality for processing large volumes of data and Quartz provides functionality for scheduling tasks. So Quartz could complement Spring Batch, but are not excluding technologies. A common combination would be to use Quartz as a trigger for a Spring Batch job using a Cron expression and the Spring Core convenience SchedulerFactoryBean .

• I have Person.Surname field implemented as a string if I change the implementation of the field to a

  - by AndyM

  This is me going right back to basics with TDD for learning purposes. I originally implemented Person.Surname as field of type object (the simplest possible way of passing the test. I then added a test setting Person.Surname stating that the return value should be a string and set Person.Surname=20. I 'fixed' the test by changing the implementation to use string rather than object. The test now long compiles due to static type checking, so I commented it out. So I'm left with no way of leaving my intention in the test. Is there a way of having a failing test in this circumstance?

• java - POST vs JDBC

  - by Dan

  OK so here's the code: import java.io.BufferedReader; import java.io.InputStreamReader; import java.net.URL; public class Main { public static void main(String[] args) { try { URL my_url = new URL("http://www.viralpatel.net/blogs/"); BufferedReader br = new BufferedReader(new InputStreamReader(my_url.openStream())); String strTemp = ""; while(null != (strTemp = br.readLine())){ System.out.println(strTemp); } } catch (Exception ex) { ex.printStackTrace(); } } } Using this method I can use POST and GET methods using PHP scripts. I can then use the PHP scripts to the MySQL database which in turn outputs back to the java applet. Is this possible? (and safer?) Thanks.

• Is there a lightweight multipart/form-data parser in C or C++?

  - by Hongli

  I'm looking at integrating multipart form-data parsing in a web server module so that I can relieve backend web applications (often written in dynamic languages) from parsing the multipart data themselves. The multipart grammar (RFC 2046) looks non-trivial and if I implement it by hand a lot of things can go wrong. Is there already a good, lightweight multipart/form-data parser written in C or C++? I'm looking for one with no external dependencies other than the C or C++ standard library. I don't need email attachment handling or buffered I/O classes or a portability runtime or whatever, just multipart/form-data parsing. Things that I've considered: GMime - depends on glib, so no go. libapreq - too large, depends on APR, badly documented, no unit tests. I've also looked at writing a parser with Ragel, but I can't figure out how to do it because the grammar is not static: the boundary can change arbitrarily.

• Big data: An evening in the life of an actual buyer

  - by Jean-Pierre Dijcks

  Here I am, and this is an actual story of one of my evenings, trying to spend money with a company and ultimately failing. I just gave up and bought a service from another vendor, not the incumbent. Here is that story and how I think big data could actually fix this (and potentially prevent some of this from happening). In the end this story should illustrate how big data can benefit me (get me what I want without causing grief) and the company I am trying to buy something from. Note: Lots of details left out, I have no intention of being the annoyed blogger moaning about a specific company. What did I want to get? We watch TV, we have internet and we do have a land line. The land line is from a different vendor then the TV and the internet. I have decided that this makes no sense and I was going to get a bundle (no need to infer who this is, I just picked the generic bundle word as this is what I want to get) of all three services as this seems to save me money. I also want to not talk to people, I just want to click on a website when I feel like it and get it all sorted. I do think that is reality. I want to just do my shopping at 9.30pm while watching silly reruns on TV. Problem 1 - Bad links So, I'm an existing customer of the company I want to buy my bundle from. I go to the website, I click on offers. Turns out they are offers for new customers. After grumbling about how good they are, I click on offers for existing customers. Bummer, it goes to offers for new customers, so I click again on the link for offers for existing customers. No cigar... it just does not work. Big data solutions: 1) Do not show an existing customer the offers for new customers unless they are the same => This is only partially doable without login, but if a customer logs in the application should always know that this is an existing customer. But in general, imagine I do this from my home going through the internet service of this vendor to their domain... an instant filter should move me into the "existing customer route". 2) Flag dead or incorrect links => I've clicked the link for "existing customer offers" at least 3 times in under 5 seconds... Identifying patterns like this is easy in Hadoop and can very quickly make a list of potentially incorrect links. No need for realtime fixing, just the fact that this link can be pro-actively fixed across my entire web domain is a good thing. Preventative maintenance! Problem 2 - Purchase cannot be completed Apart from the fact that the browsing pattern to actually get to what I want is poorly designed, my purchase never gets past a specific point. In other words, I put something into my shopping cart and when I want to move on the application either crashes (with me going to an error page) or hangs or goes into something like chat. So I try again, and again and again. I think I tried this entire path (while being logged in!!) at least 10 times over the course of 20 minutes. I also clicked on the feedback button and, frustrated as I was, tried to explain this did not work... Big Data Solutions: 1) This web site does shopping cart analysis. I got an email next day stating I have things in my shopping cart, just click here to complete my purchase. After the above experience, this just added insult to my pain... 2) What should have happened, is a Hadoop job going over all logged in customers that are on the buy flow. It should flag anyone who is trying (multiple attempts from the same user to do the same thing), analyze the shopping card, the clicks to identify what the customers wants, his feedback provided (note: always own your own website feedback, never just farm this out!!) and in a short turn around time (30 minutes to 2 hours or so) email me with a link to complete my purchase. Not with a link to my shopping cart 12 hours later, but a link to actually achieve what I wanted... Why should this company go through the big data effort? I do believe this is relatively easy to do using our Oracle Event Processing and Big Data Appliance solutions combined. It is almost so simple (to my mind) that it makes no sense that this is not in place? But, now I am ranting... Why is this interesting? It is because of $$$$. After trying really hard, I mean I did this all in the evening, and again in the morning before going to work. I kept on failing, But I really wanted this to work... so an email that said, sorry, we noticed you tried to get a bundle (the log knows what I wanted, where I failed, so easy to generate), here is the link to click and complete your purchase. And here is 2 movies on us as an apology would have kept me as a customer, and got the additional $$$$ per month for the next couple of years. It would also lead to upsell on my phone package etc. Instead, I went to a completely different company, bought service from them. Lost money for company A, negative sentiment for company A and me telling this story at the water cooler so I'm influencing more people to think negatively about company A. All in all, a loss of easy money, a ding in sentiment and image where a relatively simple solution exists and can be in place on the software I describe routinely in this blog... For those who are coming to Openworld and maybe see value in solving the above, or are thinking of how to solve this, come visit us in Moscone North - Oracle Red Lounge or in the Engineered Systems Showcase.

• How to extract data from a text file

  - by šljaker

  I need to parse some large text file and extract Display name and area code only if it matches the following pattern: Line starts with display name (any number of words) Followed by 6 digits (can contain spaces) Followed by #text tag e.g. John doe 123 456 #text some text Display name: John doe Area code: 123 456 Test 123456 #text Display name: Test Area code: 123456 Test 123 #test Invalid, area code contains only 3 digits Test 123456 #test1 Invalid, contains invalid tag Test 123g45 #test Invalid, area code contains letters etc. I know how to open the text file and read it line by line, but having trouble with writing the regular expression. Any help would be greatly appreciated! edit: I have tried this: private static void Main(string[] args) { string text = "John Doe 123 45 #text Lorem ipsum dolor :)"; string pattern = @"(\w+)*([0-9]{2,5}).([0-9]{2,5}).#text"; Match match = Regex.Match(text, pattern, RegexOptions.IgnoreCase); if (match.Success) { string key = match.Groups[0].Value; Console.WriteLine(key); } }

• Suggestion to reverse string in c#

• Storing a reference to an object in C#

  - by Jack

  I was wondering how one could store a reference to an object in .net. That is, I would like something like the following code (note, of course, that the following code may be way off from how to actually do it): class Test { private /*reference to*/ Object a; public Test(ref int a) { this.a = a; this.a = ((int)this.a) + 1; } public Object getA() { return this.a; } } /* * ... */ static void Main(string[] args) { int a; a=3; Test t = new Test(ref a); Console.WriteLine(a); Console.WriteLine(t.getA()); Console.ReadKey(); } To produce the following output: 4 4 Ideally, I would like to do this without writing a wrapper class around the integer. In other words, I think I want pointers in .Net.

• What's the smartest way to organize SVN for translated versions of the same project?

  - by brandonjp

  I apologize because I know this has been covered over and over again, but I'm trying to understand the smartest way to cleverly use subversion to our benefit. (*Note: I know our method is not the BEST way to handle localized versions, but external factors are forcing us to work this way on current projects) We have a fairly static website in English...html, css, js, etc. After the site comes back from the translator we will have 5 variations of the same code (this week...then potentially 25 more in the future!). So we'll soon have a folder for EN, FR, SP, DE, etc. Most files (css, js, img) will remain exactly the same; and html files (structure, id's, classes) will only vary based on the localized text inside the elements. Is there any way to use clever SVN folder structuring that would help us out in the event that if a small change is needed, we don't have to manually change the files in each and every translated version of the site? Thanks! --bp

• How do I structure a GWT project?

  - by smaye81

  Hello, I have followed the basic GWT tutorial for creating a project in Eclipse. Now, I am trying to build off what I learned in the tutorial. I created a static utility class to perform some database connection logic. However, when I try to compile I get: [ERROR] Line 46: No source code is available for type com.sample.server.ConnectionUtil; did you forget to inherit a required module? Where can I put simple classes that I've created on my own? Do they have to be outside the package structure of the basic module, 'com.sample'? Or do I have to specify a whole new module in the gwt.xml file and inherit from that? There has to be something simple I'm missing.

• how can i get proper Uri of a particular contact in android 2.1

  - by Rishabh

  I have written an application and added 2 contacts on emulator, but i am not able to update their names on android 2.1, code is working on android 1.6 platform with the following code. ContentValues contactValues = new ContentValues(); contactValues.put(Contacts.People.NAME, firstName+" "+lastName); getContentResolver().update(UpdateContactUri, contactValues, null, null); In android 1.6 i am getting Uri for those two contacts are "content:// contacts/people/1" and "content://contacts/people/2". but in 2.1 I am getting these values are "content://contacts/people/8" and "content://contacts/people/9" and while updating its giving "java.IllegalArgumentException, Empty values" exception. When i tried to put a static Uri like "content://contacts/people/1", code was debugged sucessfully but contact was not updated. How can i resolve it, why i am not getting uri like 1.6 platform ?

• P/Invoke a Function Passed a StringBuilder

  - by andrew

  in a C# file i have a class Archiver { [DllImport("Archiver.dll")] public static extern void archive(string data, StringBuilder response); } string data is an input, and StringBuilder response is where the function writes something the archive function prototype (written in C) looks like this: void archive(char * dataChr, char * outChr); and it receives a string in dataChr, and then does a strcpy(outChr,"some big text"); from C# i call it something like this: string message = "some text here"; StringBuilder response = new StringBuilder(10000); Archiver.archive(message,response); this works, but the problem, as you might see is that i give a value to the StringBuilder size, but the archive function might give back a (way) larger text than the size i've given to my StringBuilder. any way to fix this?

• AesCryptoServiceProvider not part of SymmetricAlgorithm?

  - by user330006

  I have a quick little app that steps through the possible symmetric encryption methods. I get them with the following line: private static List<Type> GetAlgorithmTypes { get { return Assembly.GetAssembly(typeof(SymmetricAlgorithm)).GetTypes().Where( type => type.IsSubclassOf(typeof(SymmetricAlgorithm))).ToList(); } } As you can see when i run this, AesCryptoServiceProvider is not a member of this group, even though it inherits from AES, which does belong to SymmetricAlgorithm and shows up in my list. This wouldn't be so much of a problem, i can manually add the provider in the group if i have too, but then if i try to retrieve this type by its name: Type t = Type.GetType("System.Security.Cryptography.AesCryptoServiceProvider"); i get a null object for AesCryptoServiceProvider, but not for any of the other items in the group. This is really strange, and i'm wondering if anyone has any ideas. It's kinda making me need to use tripleDES because of this (since my machines are all running the FIPS compliance requirement). Thanks for any help!
