• MySQL replication - rapidly growing relay bin logs

  - by Rob Forrest

  Morning all, I've got a really strange situation here this morning much like a reportedly fixed MySQL bug. http://bugs.mysql.com/bug.php?id=28421 My relay bin logs are rapidly filling with an infinite loop of junk made of this sort of thing. #121018 5:40:04 server id 101 end_log_pos 15598207 #Append_block: file_id: 2244 block_len: 8192 # at 15598352 #121018 5:40:04 server id 101 end_log_pos 15606422 #Append_block: file_id: 2244 block_len: 8192 # at 15606567 ... # at 7163731 #121018 5:38:39 server id 101 end_log_pos 7171801 #Append_block: file_id: 2243 block_len: 8192 WARNING: Ignoring Append_block as there is no Create_file event for file_id: 2243 # at 7171946 #121018 5:38:39 server id 101 end_log_pos 7180016 #Append_block: file_id: 2243 block_len: 8192 WARNING: Ignoring Append_block as there is no Create_file event for file_id: 2243 These log files grow to 1Gb within about a minute before rotating and starting again.

• How do you do an assignment of a delegate to a delegate in .NET

  - by Seth Spearman

  Hello... I just go the answer on how to pass a generic delegate as a parameter. Thanks for the help. Now I need to know how to ASSIGN the delegate to another delegate declarartion. Can this be done? Public Class MyClass Public Delegate Function Getter(Of TResult)() As TResult ''#the following code works. Public Shared Sub MyMethod(Of TResult)(ByVal g As Getter(Of TResult)) ' I want to assign Getter = g 'how do you do it. End Sub End Class Notice that Getter is now private. How can I ASSIGN Getter = G When I try Getter = g 'I get too few type arguments compile error. When I try Getter(Of TResult) = g 'I get Getter is a type and cannot be used as an expression.

• FlexUnit nested async tests

  - by sharvey

  I'm trying to test some async functionality in flex 4. My test has two stages : var loader:MySuperLoader = new MySuperLoader() loader.load('foo.swf'); loader.addEventListener(Event.COMPLETE, Async.asyncHandler(this, function(e:Event):void { loader.removeEventListener(Event.COMPLETE, arguments.callee); var foo:* = loader.content; loader.load('bar.swf'); loader.addEventListener(Event.COMPLETE, Async.asyncHandler(this, function(e:Event):void { /* This call to asyncHandler generates the error */ }, 5000)); }, 5000)); The second call to asyncHandler generates an error saying : Error: Cannot add asynchronous functionality to methods defined by Test,Before or After that are not marked async Is there a way to test such funcitonality?

• String Formatting Tricks/Docs

  - by Meltemi

  Was reading the response by Shaggy Frog to this post and was intrigued by the following line of code: NSLog(@"%@", [NSString stringWithFormat:@"%@:%*s%5.2f", key, padding, " ", [object floatValue]]); I know string formatting is an age old art but I'm kinda doing the end around into Cocoa/Obj-C programming and skipped a few grades along the way. Where is a good (best) place to learn all the string formatting tricks allowed in NSString's stringWithFormat? I'm familiar with Apple's String Format Specifiers page but from what I can tell it doesn't shed light on whatever is happening with %*s or the %5.2f (not to mention the 3 apparent placeholders followed by 4 arguments) above?!?

• MySQL binlogs seems incomplete?

• [JavaScript-CSS-Firefox] Cannot change borderColor of TD

  - by Tadeus Prastowo

  Using JS to set the background color of a TD is fine. But, setting the border color is problematic in FF 3.0.18 although IE 6 doesn't experience this. FF is problematic in that it requires the TD element to have an attribute style initialized to border-style: solid. Without that, setting border color of a TD won't work. Is this known bug? How do I set the border color without having to set style attribute as well as the initialization value? I know another trick of setting the class attribute instead of setting the border color directly. Is this an indication that somehow TD hates having its border color set dynamically? Is this known as well? The problematic code is below (the goal is find out why setting the border color of simple truth 1 does not work while simple truth 3 works when I employ the trick described above): <html> <head> <title>Quirks FF 3.0.18</title> <style type="text/css"> table { border-collapse: collapse; } </style> <script type="text/javascript"> function changeBgColor() { document.getElementById('simple').style.backgroundColor='yellow'; document.getElementById('simple2').style.backgroundColor='yellow'; document.getElementById('simple3').style.backgroundColor='yellow'; } function quirk(id) { var x = document.getElementById(id); x.style.border = '2px solid red'; } </script> </head> <body> <input type="button" onclick="changeBgColor()" value="Change background color"/> <input type="button" onclick="quirk('simple')" value="Change border color 1"/> <input type="button" onclick="quirk('simple2')" value="Change border color 2"/> <input type="button" onclick="quirk('simple3')" value="Change border color 3"/> <table> <tr><td id="simple">Simple truth 1</td></tr> </table> <table> <tr><td><span id="simple2">Simple truth 2</span></td></tr> <table> <tr><td id="simple3" style="border-style: solid">Simple truth 3</td></tr> </table> </body> </html>

• openCV Won't copy to image after changed color ( opencv and c++ )

  - by user1656647

  I am a beginner at opencv. I have this task: Make a new image Put a certain image in it at 0,0 Convert the certain image to gray scale put the grayscaled image next to it ( at 300, 0 ) This is what I did. I have a class imagehandler that has constructor and all the functions. cv::Mat m_image is the member field. Constructor to make new image: imagehandler::imagehandler(int width, int height) : m_image(width, height, CV_8UC3){ } Constructor to read image from file: imagehandler::imagehandler(const std::string& fileName) : m_image(imread(fileName, CV_LOAD_IMAGE_COLOR)) { if(!m_image.data) { cout << "Failed loading " << fileName << endl; } } This is the function to convert to grayscale: void imagehandler::rgb_to_greyscale(){ cv::cvtColor(m_image, m_image, CV_RGB2GRAY); } This is the function to copy paste image: //paste image to dst image at xloc,yloc void imagehandler::copy_paste_image(imagehandler& dst, int xLoc, int yLoc){ cv::Rect roi(xLoc, yLoc, m_image.size().width, m_image.size().height); cv::Mat imageROI (dst.m_image, roi); m_image.copyTo(imageROI); } Now, in the main, this is what I did : imagehandler CSImg(600, 320); //declare the new image imagehandler myimg(filepath); myimg.copy_paste_image(CSImg, 0, 0); CSImg.displayImage(); //this one showed the full colour image correctly myimg.rgb_to_greyscale(); myimg.displayImage(); //this shows the colour image in GRAY scale, works correctly myimg.copy_paste_image(CSImg, 300, 0); CSImg.displayImage(); // this one shows only the full colour image at 0,0 and does NOT show the greyscaled one at ALL! What seems to be the problem? I've been scratching my head for hours on this one!!!

• iTunes Home Sharing only works one way between 2 WinXP PC's on the same LAN

  - by scunliffe

  Both PC's have the latest iTunes installed. PC (A) can "see" that there is a shared library "B library" but attempts to connect to it return this error message: The shared library "{Username}'s Library" is not responding (-3259) Check that any firewall software running on either the shared computer or this computer has been set to allow communication on port 3689. however the reverse works fine. e.g. PC (B) can "see" shared library "A library" and can access all content. Notes: Both PC's have Home Sharing enabled (turned off/on several times to verify). Both PC's have Windows Firewall turned on, but in the exceptions tab, iTunes is allowed, and Port 3689 is also added as a firewall exception (just in case) Both iTunes accounts have been "authorized" on both PC's Both PC's connect via LAN via D-Link DIR-615 router. In the advanced application rules, iTunes has also been added to allow traffic on port 3689 un-hindered. Is there any other magical setting/configuration option that I should be aware of and set in order to get this to work? I could care less about sharing apps etc. I just want the music sharing to work. Update: Solved! It turns out on PC (B) there were multiple accounts set up. 1 of the accounts had the checkbox checked under the windows firewall "On" option which states "No exceptions" thus even though it was added to the exception list on the main user account, this other account was blocking access.

• Why do I need an IoC container as opposed to straightforward DI code?

  - by Vadim

  I've been using Dependency Injection (DI) for awhile, injecting either in a constructor, property, or method. I've never felt a need to use an Inversion of Control (IoC) container. However, the more I read, the more pressure I feel from the community to use an IoC container. I played with .NET containers like StructureMap, NInject, Unity, and Funq. I still fail to see how an IoC container is going to benefit / improve my code. I'm also afraid to start using a container at work because many of my co-workers will see code which they don't understand. Many of them may be reluctant to learn new technology. Please, convince me that I need to use an IoC container. I'm going to use these arguments when I talk to my fellow developers at work.

• Python MySQLdb placeholders syntax

  I'd like to use placeholders as seen in this example: cursor.execute (""" UPDATE animal SET name = %s WHERE name = %s """, ("snake", "turtle")) Except I'd like to have the query be its own variable as I need to insert a query into multiple databases, as in: query = """UPDATE animal SET name = %s WHERE name = %s """, ("snake", "turtle")) cursor.execute(query) cursor2.execute(query) cursor3.execute(query) What would be the proper syntax for doing something like this?

• Python 3.1.1 Class Question

  - by Protean

  I'm a new Python programmer who is having a little trouble using 'self' in classes. For example: class data: def __init__(self): self.table = [] def add(self, file): self.table.append(file) data.add('yes') In this function I want to have table be a variable stored in the class data and use add to modify it. However, when I run this script it gives me the error: Traceback (most recent call last): File "/Projects/Python/sfdfs.py", line 7, in <module> data.add('yes') TypeError: add() takes exactly 2 positional arguments (1 given) I assume that I am trying to call the function the wrong way in this instance, as this syntax is very similar to an example in the python documentation: http://docs.python.org/3.1/tutorial/classes.html

• what's the difference between a Volume and a Partition in Windows 7 diskpart

  - by user170232

  I was trying to follow the Intel guide for setting up iRST (Intel Rapid Start Technology) on my new laptop. The Intel manual says you need to create a *Volume that is as big or bigger than your available memory, set it to a specific id (id=84), then go into the iRST tool and adjust some settings. Looking at the disk manager on the laptop, I see there is already a Partition labeled as "Hibernation Partition" which is a little bigger than the memory in my system. So it looks like iRST was already set up...BUT, it's a Partition, not a Volume. Here's what the manual says to do: (from: http://download.intel.com/support/motherboards/desktop/sb/rapid_start_technology_user_guide.pdf) diskpart list disk select disk x (where x is the disk to use, there's only one disk in this laptop) create partition primary size=X000 (where X000 is the size to create) detail disk (which lists details for the disk. This is where i get hung up) select volume Z (where Z is the *partition you created previously) ** it says the 'detail disk' command will list the volume #, but it doesn't. ** 'detail disk' only lists two "volumes" for Recovery and OS. ** if i do 'list partition', i see the 8 GB *partition labeled as "Hibernation Partition") ** so I can't continue with the following steps: set id=84 override exit The reason I went looking for the manual is because when iRST is enabled in the BIOS, the system won't resume from sleep. When it's disabled, it works fine, but the system goes into (legacy?) Hibernation mode and takes a while to come out of Hibernation. the iRST is supposed to resume from deep sleep very quickly. So, what's the difference between a Volume and a Partition? Should I delete the Hibernation Partition and create a Hibernation Volume? Anyone have any ideas? (if it matters, this is on a Dell XPS 13 with BIOS A08) Thanks! J

• Qt, unit testing and mock objects.

  - by Eye of Hell

  Hello. Qt framework has internal support for testing via QtTest package. Unfortunately, i didn't find any facilities in it that can assist in creating mock objects. Qt signals and slots offers a natural way to create a unit-testing friendly units with input (slots) and output (signals). But is it any easy way to test that calling specified slot in object will result in emitting correct signals with correct arguments? Of course i can manually create a mock objects and connect them to objects being tested, but it's a lot of code. Maybe it's some techniques exists that allows to somehow automate mock objects creation while unit-testing Qt-based applications?

• Compiler warning "not found in protocol(s)" when using [[[UIApplication sharedApplication] delegate]

  - by DK Crame

  I have myClass instantiated by my appDelegate, I have another class, newClass instantiated by myClass. From the newClass instance, I want to access a property in the myClass instance that created it. I have done this by: [[[UIApplication sharedApplication].delegate myClass] property] This works, I can actually get the property but I get this warning from Xcode: warning: "-myClass" not found in protocols warning: no "-myClass" method found (messages without a matching signature will be assumed to return "id" and accept "..." as arguments) The newClass property has been correctly declared in the .h and .m files, it's properties have been set and it has been synthesized. It compiles and runs and I can actually get the property's value. Should I ignore the warning in Xcode? Is there a better way to access the myClass instance's property?

• Windows 2008 R2 remote desktop - Double Login

  - by Zulgrib

  After an Active Directory fail RDP connection started to ask for credentials twice (once on local RDP program, second time on remote's logon screen) I already looked at Windows 2008 R2 RDS - Double Login Solution provided there doesn't work for me. The server is alone, without AD/DNS services, RDP service isn't installed I tried every security settings on RDP-Tcp (RDP, Negotiate, SLL) Logon option is set to "Use credentials from the client" Both windows client and server use RDP 7.1 fPromptForPassword regitries are set to 0 Local Computer Policy\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Security\Always prompt for password upon connection is set to "Disabled" Why i am sure the problem comes from the server and not the client ? This problem affected a 3rd RDP program on Android too (it was directly showing "preparing desktop previously, on both MS RDP and the 3rd program) No bakcup are available (Else the Active Directory wouldn't be a fail, but just a lose of time) I am wondering if a rule linked to RDP got changed after the AD install+unistall, but i'm unable to find where. While this is not a critic problem, this is very annoying. I don't know if more information are needed, if it's the case and if you are patient enough, please tell me what is missing and i'll edit this post to add the missing informations.

• Send parameters in order in HTTPService

  - by Suraj Chandran

  I am trying to work with a simple HTTPService. The problem is that my webservice is conscious of the order of arguments it gets. I will tell the problem with an example: var service:HTTPService = new HTTPService(); var params:Object = new Object(); params.rows = 0; params.facet = "true"; service.send(params); Note that in the above code I have mentioned the parameter rows before facet, but the url I recieve is facet=true&rows=0. So I recieve the argument rows before facet and hence my webservice does not work. I figured out that the contents of array is always sent in alphabetical order, which I dont want. Is there any way I can achieve explict ordering of parameters sent? Note that I am not in power of changing the logic of webservice(its basically a RPC service supporting both desktop and web client). Thanks.

• T4 template for NHibernate? - not Fuent NHibernate

  - by NathanD

  Wondering if anyone knows of a set of T4 templates for generating C# POCO classes and also mapping XML files for NHibernate from a set of tables in a database. I saw that David Hayden has created T4 for generating FluentNH code based upon a DBML model, but I'm not quite ready to use FluentNH yet as there isn't even an official release yet (although I love the idea). Anyone know of any T4 templates for using plain NHibernate?

• gcc linking shared libraries with dependent libraries

  - by Geng

  I have a complicated project with multiple executable targets and multiple shared libraries. The shared libraries currently don't have their dependent shared libraries linked in, and the result is that linker arguments to build the executables are hideously long and hard to maintain. I'd like to add in the dependencies so the Makefiles become much cleaner. I want to add the following (example): gcc -shared -o libshared.so -lshared_dependent1 -lshared_dependent2 objfile1.o objfile2.o Is there a way to test if all the symbols in libshared.so will resolve based on that line? Is there a way to print out if any of the shared_dependent libraries specified were unnecessary? Thanks in advance.

• jQuery not and classes

  - by Giles B

  Hi Guys, I have 2 anchor links (a.selector) and when one is clicked it has a class applied to it of 'active-arrow' and the click also removes the class of the same name from the other anchor as well as lowering the opacity to 0.2. I then want to have a fade effect when the user hovers over the anchor that doesn't have 'active-arrow' applied to it so that it goes to full opacity when mouseenters and back to 0.2 when mouseleaves. The problem im having is that both .not and :not don't seem to be working as expected, the hover effect works but if I click on the anchor whilst hovering the 'active-arrow' class is applied but when mouseleaves the opacity is faded down to 0.2 again even though the 'active-arrow' class is applied. Also the hover then doesn't work for the other a link which has had 'active-arrow' removed. Bit of a hard one to explain so heres some code that hopefully helps a bit. *//If a.selector doesn't have the class 'active-arrow' then run the hoverFade function* $("a.selector").not(".active-arrow").hoverFade(); //Functions for first element $('a.selector-1').click(function () { $('a.selector-2').removeClass('active-arrow'); //Remove background image from corresponding element $('ul#storage-items-2').fadeOut(1200).addClass('hide'); //Fade out then hide corresponding list $(this).addClass('active-arrow', 'fast'); //Add background image to current element $('ul#storage-items-1').removeClass('hide').fadeIn(1800); //Unhide and fade in the list $('a.selector-2').fadeTo(500, 0.2); //Fade corresponding element $(this).fadeTo(800, 1);//Fade this element to full opacity }); I only included the code for teh first anchor (a.selector-1) as the code for the second anchor is identical but just changes the class names to a.selector-2. Also the hoverFade function is in a seperate file so we can re-use it. jQuery.fn.hoverFade = function() { return this.each(function(){ $(this).hover( function () { $(this).fadeTo(500, 0.8); }, function () { $(this).fadeTo(500, 0.2); }); }); } Each anchor link fades in and fades out a UL as well. Any help is most appreciated Thanks Giles
