• Does Win 7 still requires copying all files over before burning to a DVD-R or BD-R?

  - by Jian Lin

  It seems that Win 7 still needs to copy all files over to a folder, before it burns all files to the DVD-R or BD-R? I think since XP or Vista, Windows always copy everything over to a temporary folder before it will burn to an empty DVD-R. So if you just want to burn a 4GB file to an empty DVD-R, it will first make a copy of that file, and then burn it, instead of just burning it without making a copy first. And now on Win 7, it seems like it is the case also? Most other 3rd party burning tools won't make an extra copy of the files first... Win 7 is the exception. Is there a way around it? (to avoid copying over 25GB or 50GB of data before burning)

• Develop a small size software using C only for copying same data to multiple external drives simultaneously [on hold]

  - by VSP

  I want to develop a software that can copy the same data to multiple external drives, simultaneously. For example, consider a file Movie and I have 3 external drives to copy it to, and I want to copy Movie to all these 3 drives(these drives can be flash storage or external hard-disk or pen-drive etc. but have one thing in common, i.e. they are all external drives) at the same time, means when I right-click on Movie there has to be 1 option saying Copy to All Drives. It's a sort of mini-project and I want to use C language only. For starting I would like it to work only on Windows OS. What are the requirements of developing this software (not the system requirements but what will I need to develop such a software, like editor,compiler etc.)? I know this type of software must have already been developed but I want to use C language and C Language only. So, is it possible to develop such a software?

• Searching for context in Silverlight applications

  - by PeterTweed

  A common behavior in business applications that have developed through the ages is for a user to be able to get information or execute commands in relation to some information/function displayed by right clicking the object in question and popping up a context menu that offers relevant options to choose. The Silverlight Toolkit April 2010 release introduced the context menu object.  This can be added to other UI objects and display options for the user to choose.  The menu items can be enabled or disabled as per your application logic and icons can be added to the menu items to add visual effect.  This post will walk you through how to use the context menu object from the Silverlight Toolkit. Steps: 1. Create a new Silverlight 4 application 2. Copy the following namespace definition to the user control object of the MainPage.xaml file: xmlns:my="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Input.Toolkit"   3. Copy the following XAML into the LayoutRoot grid in MainPage.xaml:          <Border CornerRadius="15" Background="Blue" Width="400" Height="100">             <TextBlock Foreground="White" FontSize="20" Text="Context Menu In This Border...." HorizontalAlignment="Center" VerticalAlignment="Center" >             </TextBlock>             <my:ContextMenuService.ContextMenu>                 <my:ContextMenu >                     <my:MenuItem                 Header="Copy"                 Click="CopyMenuItem_Click" Name="copyMenuItem">                         <my:MenuItem.Icon>                             <Image Source="copy-icon-small.png"/>                         </my:MenuItem.Icon>                     </my:MenuItem>                     <my:Separator/>                     <my:MenuItem Name="pasteMenuItem"                 Header="Paste"                 Click="PasteMenuItem_Click">                         <my:MenuItem.Icon>                             <Image Source="paste-icon-small.png"/>                         </my:MenuItem.Icon>                     </my:MenuItem>                 </my:ContextMenu>             </my:ContextMenuService.ContextMenu>         </Border>   The above code associates a context menu with two menu items and a separator between them to the border object.  The menu items has icons associated with them to add visual appeal.  The menu items have click event handlers that will be added in the MainPage.xaml.cs code behind in a later step. 4. Add two icon sized images to the ClientBin directory of the web project hosting the Silverlight application, named copy-icon-small.png and paste-icon-small.jpg respectively.  I used copy and paste icons as the names suggest. 5. Add the following code to the class in MainPage.xaml.cs file:         private void CopyMenuItem_Click(object sender, RoutedEventArgs e)         {             MessageBox.Show("Copy selected");         }           private void PasteMenuItem_Click(object sender, RoutedEventArgs e)         {             MessageBox.Show("Paste selected");         }   This code adds the event handlers for the menu items defined in step 3. 6. Run the application, right click on the border and select a menu option and see the appropriate message box displayed. Congratulations it’s that easy!   Take the Slalom Challenge at www.slalomchallenge.com!

• .bashrc doesn't get sourced after su'ing to root

  - by Ian Dunn

  I've got a CentOS 5.6 VPS and both root and my normal user account have identical copies of a .bashrc file in their home directories. The file contains a few basic aliases, etc. If I login to root, root's copy gets sourced. If I login to myuser, myuser's copy gets sourced If I su to root after logging into myuser, then all the aliases, etc inside myuser's copy get removed, and root's copy doesn't get sourced. If I then manually source root's copy, the command completes without any errors, but none of the aliases's etc get applied. I've searched Google and Server Fault, but haven't found any solutions. Does anyone know how to fix that?

• Storing a pass-by-reference parameter as a pointer - Bad practice?

  - by Karl Nicoll

  I recently came across the following pattern in an API I've been forced to use: class SomeObject { public: // Constructor. SomeObject(bool copy = false); // Set a value. void SetValue(const ComplexType &value); private: bool m_copy; ComplexType *m_pComplexType; ComplexType m_complexType; }; // ------------------------------------------------------------ SomeObject::SomeObject(bool copy) : m_copy(copy) { } // ------------------------------------------------------------ void SomeObject::SetValue(const ComplexType &value) { if (m_copy) m_complexType.assign(value); else m_pComplexType = const_cast<ComplexType *>(&value); } The background behind this pattern is that it is used to hold data prior to it being encoded and sent to a TCP socket. The copy weirdness is designed to make the class SomeObject efficient by only holding a pointer to the object until it needs to be encoded, but also provide the option to copy values if the lifetime of the SomeObject exceeds the lifetime of a ComplexType. However, consider the following: SomeObject SomeFunction() { ComplexType complexTypeInstance(1); // Create an instance of ComplexType. SomeObject encodeHelper; encodeHelper.SetValue(complexTypeInstance); // Okay. return encodeHelper; // Uh oh! complexTypeInstance has been destroyed, and // now encoding will venture into the realm of undefined // behaviour! } I tripped over this because I used the default constructor, and this resulted in messages being encoded as blank (through a fluke of undefined behaviour). It took an absolute age to pinpoint the cause! Anyway, is this a standard pattern for something like this? Are there any advantages to doing it this way vs overloading the SetValue method to accept a pointer that I'm missing? Thanks!

• What's the best subversion client to use for a working copy on a network share that's being modified by other users without a subversion client?

  - by loupai

  That probably sounds confusing. Here's my situation: I have a software project I'd like to version control with Subversion. The project files are on a network share which is modified by several users. I'd like to version control the directory with caveat that many of the users are not going to be using a SVN client when they add, modify, move, and rename files. I'll be doing all the version control myself along with one or two other users. When I commit the changes with an SVN client I'd assume that all changes made to file, all deletions, renames, etc are intentional. So how do I detect these changes if as user made them without using a client like TortoiseSVN? Can anyone recommend a client that could determine possible renames, deletions, and moved files? Thanks!

• Cocoa equivalent of the Carbon method getPtrSize

  - by Michael Minerva

  I need to translate the a carbon method into cocoa into and I am having trouble finding any documentation about what the carbon method getPtrSize really does. From the code I am translating it seems that it returns the byte representation of an image but that doesn't really match up with the name. Could someone give me a good explanation of this method or link me to some documentation that describes it. The code I am translating is in a common lisp implementation called MCL that has a bridge to carbon (I am translating into CCL which is a common lisp implementation with a Cocoa bridge). Here is the MCL code (#_before a method call means that it is a carbon method): (defmethod COPY-CONTENT-INTO ((Source inflatable-icon) (Destination inflatable-icon)) ;; check for size compatibility to avoid disaster (unless (and (= (rows Source) (rows Destination)) (= (columns Source) (columns Destination)) (= (#_getPtrSize (image Source)) (#_getPtrSize (image Destination)))) (error "cannot copy content of source into destination inflatable icon: incompatible sizes")) ;; given that they are the same size only copy content (setf (is-upright Destination) (is-upright Source)) (setf (height Destination) (height Source)) (setf (dz Destination) (dz Source)) (setf (surfaces Destination) (surfaces Source)) (setf (distance Destination) (distance Source)) ;; arrays (noise-map Source) ;; accessor makes array if needed (noise-map Destination) ;; ;; accessor makes array if needed (dotimes (Row (rows Source)) (dotimes (Column (columns Source)) (setf (aref (noise-map Destination) Row Column) (aref (noise-map Source) Row Column)) (setf (aref (altitudes Destination) Row Column) (aref (altitudes Source) Row Column)))) (setf (connectors Destination) (mapcar #'copy-instance (connectors Source))) (setf (visible-alpha-threshold Destination) (visible-alpha-threshold Source)) ;; copy Image: slow byte copy (dotimes (I (#_getPtrSize (image Source))) (%put-byte (image Destination) (%get-byte (image Source) i) i)) ;; flat texture optimization: do not copy texture-id -> destination should get its own texture id from OpenGL (setf (is-flat Destination) (is-flat Source)) ;; do not compile flat textures: the display list overhead slows things down by about 2x (setf (auto-compile Destination) (not (is-flat Source))) ;; to make change visible we have to reset the compiled flag (setf (is-compiled Destination) nil))

• Another IKImageView Question

  - by Brian Postow

  I'm trying to use the select and copy feature of the IKImageView. If all you want to do is have an app with an image, select a portion and copy it to the clipboard, it's easy. You set the copy menu pick to the first responder's copy:(id) method and magically everything works. However, if you want something more complicated, like you want to copy as part of some other operation, I can't seem to find the method to do this. IKImageView doesn't seem to have a copy method, it doesn't seem to have a method that will even tell you the selected rectangle! I have gone through Hillegass' book, so I understand how the clipboard works, just not how to get the portion of the image out of the view... Now, I'm starting to think that I made a mistake in basing my project on IKImageView, but it's what Preview is built on (or so I've read), so I figured it had to be stable... and anyway, now it's too late, I'm too deep in this to start over... So, other than not using IKImageView, any suggestions on how to copy the select region to the clipboard manually?

• Scala: Correcting type inference of representation type over if statement

  - by drhagen

  This is a follow-up to two questions on representation types, which are type parameters of a trait designed to represent the type underlying a bounded type member (or something like that). I've had success creating instances of classes, e.g ConcreteGarage, that have instances cars of bounded type members CarType. trait Garage { type CarType <: Car[CarType] def cars: Seq[CarType] def copy(cars: Seq[CarType]): Garage def refuel(car: CarType, fuel: CarType#FuelType): Garage = copy( cars.map { case `car` => car.refuel(fuel) case other => other }) } class ConcreteGarage[C <: Car[C]](val cars: Seq[C]) extends Garage { type CarType = C def copy(cars: Seq[C]) = new ConcreteGarage(cars) } trait Car[C <: Car[C]] { type FuelType <: Fuel def fuel: FuelType def copy(fuel: C#FuelType): C def refuel(fuel: C#FuelType): C = copy(fuel) } class Ferrari(val fuel: Benzin) extends Car[Ferrari] { type FuelType = Benzin def copy(fuel: Benzin) = new Ferrari(fuel) } class Mustang(val fuel: Benzin) extends Car[Mustang] { type FuelType = Benzin def copy(fuel: Benzin) = new Mustang(fuel) } trait Fuel case class Benzin() extends Fuel I can easily create instances of Cars like Ferraris and Mustangs and put them into a ConcreteGarage, as long as it's simple: val newFerrari = new Ferrari(Benzin()) val newMustang = new Mustang(Benzin()) val ferrariGarage = new ConcreteGarage(Seq(newFerrari)) val mustangGarage = new ConcreteGarage(Seq(newMustang)) However, if I merely return one or the other, based on a flag, and try to put the result into a garage, it fails: val likesFord = true val new_car = if (likesFord) newFerrari else newMustang val switchedGarage = new ConcreteGarage(Seq(new_car)) // Fails here The switch alone works fine, it is the call to ConcreteGarage constructor that fails with the rather mystical error: error: inferred type arguments [this.Car[_ >: this.Ferrari with this.Mustang <: this.Car[_ >: this.Ferrari with this.Mustang <: ScalaObject]{def fuel: this.Benzin; type FuelType<: this.Benzin}]{def fuel: this.Benzin; type FuelType<: this.Benzin}] do not conform to class ConcreteGarage's type parameter bounds [C <: this.Car[C]] val switchedGarage = new ConcreteGarage(Seq(new_car)) // Fails here ^ I have tried putting those magic [C <: Car[C]] representation type parameters everywhere, but without success in finding the magic spot.

• Behavior difference between UIView.subviews and [NSView subviews]

  - by zpasternack

  I have a piece of code in an iPhone app, which removes all subviews from a UIView subclass. It looks like this: NSArray* subViews = self.subviews; for( UIView *aView in subViews ) { [aView removeFromSuperview]; } This works fine. In fact, I never really gave it much thought until I tried nearly the same thing in a Mac OS X app (from an NSView subclass): NSArray* subViews = [self subviews]; for( NSView *aView in subViews ) { [aView removeFromSuperview]; } That totally doesn’t work. Specifically, at runtime, I get this: *** Collection <NSCFArray: 0x1005208a0> was mutated while being enumerated. I ended up doing it like so: NSArray* subViews = [[self subviews] copy]; for( NSView *aView in subViews ) { [aView removeFromSuperview]; } [subViews release]; That's fine. What’s bugging me, though, is why does it work on the iPhone? subviews is a copy property: @property(nonatomic,readonly,copy) NSArray *subviews; My first thought was, maybe @synthesize’d getters return a copy when the copy attribute is specified. The doc is clear on the semantics of copy for setters, but doesn’t appear to say either way for getters (or at least, it’s not apparent to me). And actually, doing a few tests of my own, this clearly does not seem to be the case. Which is good, I think returning a copy would be problematic, for a few reasons. So the question is: how does the above code work on the iPhone? NSView is clearly returning a pointer to the actual array of subviews, and perhaps UIView isn’t. Perhaps it’s simply an implementation detail of UIView, and I shouldn’t get worked up about it. Can anyone offer any insight?

• avconv gets killed if mkv has subtitles

  - by Lukas Knuth

  What I'm trying to do is to take a movie (in an Matroska container), convert all audio tracks to AC3 and don't touch anything else. I'm using this line: avconv -i infile.mkv -map 0 -vcodec copy -scodec copy -acodec ac3 -ab 256k outfile.mkv This works fine, except when there are subtitles embedded. Then, after some time processing with no progress, avconv just "dies" (output shortened, these seem to be the interesting parts): [matroska,webm @ 0xf867a0] max_analyze_duration reached [matroska,webm @ 0xf867a0] Estimating duration from bitrate, this may be inaccurate ...

• What is the difference between a PDU and a power strip (both 120V, 15A)?

  - by rob

  I just chatted with an APC rep about upgrading the UPSes at our office. She recommended a single higher-capacity 6-outlet Smart-UPS to replace the four Back-UPS units we currently have. When I asked how she recommended plugging in all the current devices, she recommended using a APC's AP9567 PDU, but said not to use a power strip. At first she said I had to use an APC brand PDU, but after I inquired about using a Tripp-Lite PDU, she said any brand PDU would be fine. The APC PDU previously referenced looks like a standard 120V power strip with overload protection but no surge protection. Other than overload protection (which seems redundant if plugging into the UPS), is there something else I'm missing, or should any power strip (without surge protection) be fine? Edit: I didn't mention it earlier, but we don't have a proper rack--though I did still plan to mount the PDU or power strip to something. I guess I'm wondering if there's any special reason I should pay as much as $180 for the low-end APC PDU (which just looks like a power strip to me) vs. $20-$30 for a workbench power strip.

• Is it possible to use ffmpeg to trim off X seconds from the beginning of a video with an unspecified length?

  - by marcelebrate

  I need to trim the just the first 1 or 2 seconds off of a series of FLV recordings of varying, unspecified lengths. I've found plenty of resources for extracting a specified duration from a video (e.g. 30 second clips), but none for continuing to the end of a video. Both of these attempts just yield a copied version of the video, sans desired trimming: ffmpeg -ss 2 -vcodec copy -acodec copy -i input.flv output.flv ffmpeg -ss 2 -t 120 -vcodec copy -acodec copy -i input.flv output.flv The thought on the second one was: perhaps if I specified a length beyond what was possible, it'd just go to the end. No dice. I know it's not an issue with codecs or using seconds instead of timecode since the following worked a charm: ffmpeg -ss 2 -t 5 -vcodec copy -acodec copy -i input.flv output.flv Any other ideas? I'm open to using other (Windows-based) command line tools, however am strongly favoring ffmpeg since I'm already using it for thumbnail creation and am familiar with it. If it helps, my videos will all be under 2 minutes.

• Slow wifi from Windows Server 2003 virtualized in XenServer

  - by John Clayton

  I'm a brand spanking new user of OS X, coming from a lifetime of Windows use. I've been setting up my new Macbook Pro and have run into a very unusual problem. Over wifi, I am unable to copy files to or from my Windows Home Server. The problem seems to exist only over wifi, and only to WHS. Here are the details of my setup: 2010 Macbook Pro (Core i7), OS X 10.6.3 Windows Home Server PP3 (virtualized in XenServer 5.5) Windows 7 Ultimate x64 desktop Windows 7 Ultimate x64 in Boot Camp D-Link DIR-655 wireless N router Here is what I've done to narrow down the problem: Files copy fine from WHS to OS X when using gigabit ethernet Files copy fine from desktop to OS X when using gigabit ethernet Files fail to copy from WHS to OS X when using wifi (error -51) Files copy fine from desktop to OS X when using wifi Files copy fine from WHS to Boot Camp when using wifi Files copy fine from desktop to Boot Camp when using wifi From what I can tell, it seems to be some sort of issue between OS X and WHS, but I can't for the life of me see what would be different between shares on WHS and my desktop. They are both connected using smb://ADDRESS (I've tried both by IP and name). I can browse the shares on the WHS, but copying to OS X fails. I originally found the issue while installing VS2010 off an ISO from WHS, mounted to a Windows 7 VM using VMware Fusion. During the installation the VM was unusable - even the clock got behind the host be about 8 minutes. Once I plugged in the ethernet and disabled the wifi things picked up and finished quickly. The Fusion 3.1 RC is the only I think of that I installed that may have messed with the wifi driver. I've also tried resetting the wifi router, and have changed it from being G & N to N-only. Under Boot Camp I get similar speeds as my wife's N laptop. Any ideas? Thanks! Update: The issue has been further narrowed down to Windows Server 2003, which Windows Home Server is based on, running in XenServer with the XenServer tools installed.

  I want to write an apps that accepts user command. The user command is used in this format: command -parameter For example, the app can have "Copy", "Paste", "Delete" command I am thinking the program should work like this : public static void main(String args[]){ if(args[0].equalsIgnoreCase("COPY")){ //handle the copy command } else if(args[0].equalsIgnoreCase("PASTE")){ //handle the copy command }/** code skipped **/ } So, it works, but I think it will become more and more complex when I have more command in my program, also, it is different to read. Any ideas to simply the logic?

  Hello guys, I'm having troubles with the logic and would apprecite any help/tips. I have <Deposits> elements and <Receipts> elements. However there isn't any identification what receipt was paid toward what deposit. I am trying to update the <Deposits> elements with the following attributes: @DueAmont - the amount that is still due to pay @Status - whether it's paid, outstanding (partly paid) or due @ReceiptDate - the latest receipt's date that was paid towards this deposit Every deposit could be paid with one or more receipts. It also could happen, that 1 receipt could cover one or more deposits. For example. If there are 3 deposits: 500 100 450 That are paid with the following receipts: 200 100 250 I want to get the following info: Deposit 1 is fully paid (status=paid, dueAmount=0, receiptNum=3. Deposit 2 is partly paid (status=outstanding, dueAmount=50, receiptNum=3. Deposit 3 is not paid (status=due, dueAmount=450, receiptNum=NAN. I've added comments in the code explaining what I'm trying to do. I am staring at this code for the 3rd day now non stop - can't see what I'm doing wrong. Please could anyone help me with it? :) Thanks! Set up: $deposits - All the available deposits $receiptsAsc - All the available receipts sorted by their @ActionDate Code: <!-- Accumulate all the deposits with @Status, @DueAmount and @ReceiptDate attributes Provide all deposits, receipts and start with 1st receipt --> <xsl:variable name="depositsClassified"> <xsl:call-template name="classifyDeposits"> <xsl:with-param name="depositsAll" select="$deposits"/> <xsl:with-param name="receiptsAll" select="$receiptsAsc"/> <xsl:with-param name="receiptCount" select="'1'"/> </xsl:call-template> </xsl:variable> <!-- Recursive function to associate deposits' total amounts with overall receipts paid to determine whether a deposit is due, outstanding or paid.

• Best practice? Using DPM to backup VMs within each VM or through the host?

  - by andrew

  We've got two Hyper-V hosts running multiple VMs (all flavors of Windows Servers). One of the VMs is running MS Data Protection Manager 2010, which runs beautifully (most of the time) and is connected to a separate NAS via iSCSI for the DPM storage. I noticed when I installed the DPM agent on the Hyper-V hosts, it enumerates the VMs in the DPM Protection listing. I don't want to burn through my storage space too fast with duplicate protection, so I was wondering: Is it recommended to back up VMs through the host, or is it better to install the DPM agent on each VM and backup as I would any other machine? It would seem as though most people (currently including me) do it the second way, but is there any advantage to including the entries under HyperV (Backup using Child Partition Snapshop)?
