  • Alpha transparent PNGs not displaying correctly in Mobile Safari

    - by worksology
    I'm using some semi-transparent PNGs as background-images on various websites. These are usually something like a 1x1 image with a 30-percent opaque white layer. I've noticed that Mobile Safari does not display them correctly, giving them a darker/grayish tint. I've created a couple test pages to illustrate. View them both in your normal browser, and then on Mobile Safari, and you should see what I mean. This shows 11 red images of varying opacities on white: http://thecompleteworks.org/alpha-tests/index-red.html This shows 11 white images of varying opacities on blue: http://thecompleteworks.org/alpha-tests/index.html Is this a MobileSafari bug (I couldn't imagine so), or do I need to do something different, either to my pages or PNGs? (Here's how I create the PNGs: In Photoshop, create a 1x1 transparent canvas. Draw a white rectangle in Layer 1. Set opacity to, say 30 percent, Save for Web as 24-bit PNG with transparency.)

  • OpenGLES mix and match blending options complicated question

    - by DevDevDev
    So I have a background line drawing, black and white. I want to be able to draw over this, keeping the black lines in there, and drawing only where it is white. I can do this by using glBlendFunc(GL_DST_COLOR, GL_ONE_MINUS_SRC_ALPHA); And the black stays black and white gets whatever color I want. However in the white areas, I want to be able to draw some color, pick to another color and then blend. However this doesn't work because the blend function is messed up. So what I was thinking is having a linedrawing framebuffer, and a user-drawing framebuffer. The user draws into the userdrawing framebuffer, with a different blending, and then I switch blending options and draw into the linedrawing framebuffer. But i don't know enough OpenGL to say whether or not this will work or is a stupid idea. Thanks a lot

  • How apply a storyboard to a Label programmatically ?

    - by ThitoO
    Hi :), I've a little problem, I'd search google and my Wpf's books but I don't found any answer :( I have created a little storyboard : <Storyboard x:Key="whiteAnim" Duration="1"> <ColorAnimation By="Black" To="White" Storyboard.TargetProperty="Background" x:Name="step1"/> <ColorAnimation By="White" To="Black" Storyboard.TargetProperty="Background" x:Name="step2"/> </Storyboard> This animation will change background color from black to white, and from white to black. I want to "apply" this storyboard to a Label : Label label = new Label(); label.Content = "My label"; I'm looking for a method like "label.StartStoryboard(--myStoryboard--), do you have any ideas ? Thank you :)

  • Why does calling IEnumerable<string>.Count() create an additional assembly dependency ?

    - by Gishu
    Assume this chain of dll references Tests.dll >> Automation.dll >> White.Core.dll with the following line of code in Tests.dll, where everything builds result.MissingPaths Now when I change this to result.MissingPaths.Count() I get the following build error for Tests.dll "White.UIItem is not defined in an assembly that is not referenced. You must add a reference to White.Core.dll." And I don't want to do that because it breaks my layering. Here is the type definition for result, which is in Automation.dll public class HasResult { public HasResult(IEnumerable<string> missingPaths ) { MissingPaths = missingPaths; } public IEnumerable<string> MissingPaths { get; set; } public bool AllExist { get { return !MissingPaths.Any(); } } } Down the call chain the input param to this ctor is created via (The TreeNode class is in White.Core.dll) assetPaths.Where(assetPath => !FindTreeNodeUsingCache(treeHandle, assetPath)); Why does this dependency leak when calling Count() on IEnumerable ? I then suspected that lazy evaluation was causing this (for some reason) - so I slotted in an ToArray() in the above line but didn't work. Update 2011 01 07: Curiouser and Curiouser! it won't build until I add a White.Core reference. So I add a reference and build it (in order to find the elusive dependency source). Open it up in Reflector and the only references listed are Automation, mscorlib, System.core and NUnit. So the compiler threw away the White reference as it was not needed. ILDASM also confirms that there is no White AssemblyRef entry. Any ideas on how to get to the bottom of this thing (primarily for 'now I wanna know why' reasons)? What are the chances that this is an VS2010/MSBuild bug? Update 2011 01 07 #2 As per Shimmy's suggestion, tried calling the method explcitly as an extension method Enumerable.Count(result.MissingPaths) and it stops cribbing (not sure why). However I moved some code around after that and now I'm getting the same issue at a different location using IEnumerable - this time reading and filtering lines out of a file on disk (totally unrelated to White). Seems like it's a 'symptom-fix'. var lines = File.ReadLines(aFilePath).ToArray(); once again, if I remove the ToArray() it compiles again - it seems that any method that causes the enumerable to be evaluated (ToArray, Count, ToList, etc.) causes this. Let me try and get a working tiny-app to demo this issue... Update 2011 01 07 #3 Phew! More information.. It turns out the problem is just in one source file - this file is LINQ-phobic. Any call to an Enumerable extension method has to be explicitly called out. The refactorings that I did caused a new method to be moved into this source file, which had some LINQ :) Still no clue as to why this class dislikes LINQ. using System; using System.Collections.Generic; using System.IO; using System.Linq; using G.S.OurAutomation.Constants; using G.S.OurAutomation.Framework; using NUnit.Framework; namespace G.S.AcceptanceTests { public abstract class ConfigureThingBase : OurTestFixture { .... private static IEnumerable<string> GetExpectedThingsFor(string param) { // even this won't compile - although it compiles fine in an adjoining source file in the same assembly //IEnumerable<string> s = new string[0]; //Console.WriteLine(s.Count()); // this is the line that is now causing a build failure // var expectedInfo = File.ReadLines(someCsvFilePath)) // .Where(line => !line.StartsWith("REM", StringComparison.InvariantCultureIgnoreCase)) // .Select(line => line.Replace("%PLACEHOLDER%", param)) // .ToArray(); // Unrolling the LINQ above removes the build error var expectedInfo = Enumerable.ToArray( Enumerable.Select( Enumerable.Where( File.ReadLines(someCsvFilePath)), line => !line.StartsWith("REM", StringComparison.InvariantCultureIgnoreCase)), line => line.Replace("%PLACEHOLDER%", param)));

  • Word-wrap grid cells in Ext JS

    - by richardtallent
    (This is not a question per se, I'm documenting a solution I found using Ext JS 3.1.0. But, feel free to answer if you know of a better solution!) The Column config for an Ext JS Grid object does not have a native way to allow word-wrapped text, but there is a css property to override the inline CSS of the TD elements created by the grid. Unfortunately, the TD elements contain a DIV element wrapping the content, and that DIV is set to white-space:nowrap by Ext JS's stylesheet, so overriding the TD CSS does no good. I added the following to my main CSS file, a simple fix that appears to not break any grid functionality, but allows any white-space setting I apply to the TD to pass through to the DIV. .x-grid3-cell { /* TD is defaulted to word-wrap. Turn it off so it can be turned on for specific columns. */ white-space:nowrap; } .x-grid3-cell-inner { /* Inherit DIV's white-space from TD parent, since DIV's inline style is not accessible in the column definition. */ white-space:inherit; } YMMV, but it works for me, wanted to get it out there as a solution since I couldn't find a working solution by searching the Interwebs.

  • Override transparency color when converting transparent PNG to JPG

    - by Alexander Malfait
    I'm using Dragonfly to generate thumbnail images in a Rails app. I'm serving all picture images as JPG's. Now the client is uploading transparent PNG files, like this one: http://www.ibanez.co.jp/products/images/eg2010/ART120_TRF_12_02.png Dragonfly uses RMagick to convert these images to JPG. The problem is that it converts the PNG images to JPG with a black background, and my site's design requires a white background. I've tried to override it like this: encoded_image = Magick::Image.from_blob(image.data).first if encoded_image.format.downcase == format image # do nothing else encoded_image.format = format encoded_image.background_color = "white" encoded_image.transparent_color = "white" encoded_image.to_blob end But the produced JPG images still contain a black background. Does anyone know how to beat RMagick into using a white background when converting the transparent layer? I know I could just serve as PNG, but then the images are 10 times as large, and the site is already pretty bandwidth heavy.

  • jquery manipulate a tags with .css()

    - by jesse
    I need to change the font color of a div with the id name "nav" to white. I did: $("#nav").css("color","white"); This works for all the text that isn't wrapped in < a tags but I need those changed too. I tried adding: $("a").css("color","white"); But that doesn't work. I also tried: var changeAColor = document.getElementsByTagName("a") $(changeAColor).css("color","white"); Any ideas appreciated.

  • Changing Color with LinearLayout and TextView in Java (Android)

    - by Rob S.
    I'm a relatively new Android developer and I noticed what seems like an oddity to me that I'm hoping someone can explain. I have LinearLayout ll. This line of code fails for me when executed: ll.setBackgroundColor(R.color.white); However this line of code works: ll.setBackgroundResource(R.color.white); I assume its simply because I have white defined in my resources. However, I've also tried passing 0xFFFFFF in setBackgroundColor() and that doesn't work either. Similarly with my TextView text this line of code fails when executed: text.setTextColor(R.color.white); I can see my TextView so I know I initialized it correctly (like my LinearLayout which I can also see). So I guess my question boils down to: How do I properly use LinearLayout.setBackgroundColor() and TextView.setTextColor() ? Thanks a ton in advance. I've read through the docs and tried to find information online via googling and haven't come up with anything.

  • Using selector to change TextView text color

    - by rafuru
    I'm trying to use a TextView to define the style of a TabWidget on a tabhost. I just created a selector for bgcolor and works fine, but i want to make a selector for textColor but the text color don't change: This is my tab_text_selector.xml: <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android" > <item android:state_selected="true" android:color="@android:color/white" /> <item android:state_focused="true" android:color="@android:color/white" /> <item android:state_pressed="true" android:color="@android:color/white" /> </selector> And this is the code when i'm trying to use on a textView: TextView txtTab=new TextView(this); txtTab.setTextColor(R.drawable.tab_text_selector); txtTab.setBackgroundResource(R.drawable.tab_bg_selector); txtTab.setGravity(Gravity.CENTER); txtTab.setText("Agregar Idea"); I know the text color must be white in any case but it doesn't.

  • Background Image Overlapped Problem with jQuery

    - by Devyn
    Hi, Here is my working page. I attached buttons to white bishop and you can move around but left images are overlapped by right images. I think the problem is with CSS. The brief structure is here. <script> $(document).ready(function(){ $('#top').click(function(){ $('#p81').animate({top: "-=64px"}, 100); }); </script> <style> div.chess_board{ height: 512px; position: relative; width: 512px; } div.chess_square{ height:64px; position: absolute; width:64px; } div.chess_square.white { background: none repeat scroll 0 0 #ffffff; } . . . div.chess_piece{ background-image: url("sprite.png"); height: 64px; width: 64px; position: absolute; } div.chess_piece.bishot.white{ background-position: -64px 0; } </style> <div class="chess_board"> <div id="b81" class="chess_square white" style="top: 448px; left: 64px;"> <div class="chess_square_inner"></div> <div id="p81" class="chess_piece bishot white"></div> </div> </div> <input type="button" id="top" value="top" />

  • Changing UI color in Eclipse

    - by Lo'oris
    I'm aware of this topic: I've used it to change most of the editor colors, and that's great. But that wasn't enought, there's still too much white (and I need to change it because it hurts my eyes). I've searched in the preferences (both using Eclipse itself and editing the files) for instances of while (255,255,255) and changed them all. Looks like I'm missing something. too much white in the UI: http://www.imagebanana.com/view/gy89qf7/eclipse_too_much_white_1.png totally white in this screen: http://www.imagebanana.com/view/j8282wf/eclipse_too_much_white_2.png

  • add_shown & add_hiding ModalPopupExtender Events

    - by Yousef_Jadallah
        In this topic, I’ll discuss the Client events we usually need while using ModalPopupExtender. The add_shown fires when the ModalPopupExtender had shown and add_hiding fires when the user cancels it by CancelControlID,note that it fires before hiding the modal. They are useful in many cases, for example may you need to set focus to specific Textbox when the user display the modal, or if you need to reset the controls values inside the Modal after it has been hidden. To declare Client event either in pageLoad javascript function or you can attach the function by Sys.Application.add_load like this: Sys.Application.add_load(modalInit); function modalInit() { var modalPopup = $find('mpeID'); modalPopup.add_hiding(onHiding); } function onHiding(sender, args) { } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   I’ll use the first way in the current example. So lets start with the illustration:   1- In this example am using simple panel which contain UserName and Password Textboxes besides submit and cancel buttons, this Panel will be used as PopupControlID in the ModalPopupExtender : <asp:Panel ID="panModal" runat="server" Height="180px" Width="300px" style="display:none" CssClass="ModalWindow"> <table width="100%" > <tr> <td> User Name </td> <td> <asp:TextBox ID="txtName" runat="server"></asp:TextBox> </td> </tr> <tr> <td> Password </td> <td> <asp:TextBox ID="txtPassword" runat="server" TextMode="Password"></asp:TextBox> </td> </tr> </table> <br /> <asp:Button ID="btnSubmit" runat="server" Text="Submit" /> <asp:Button ID="btnCancel" runat="server" Text="Cancel" /> </asp:Panel>   You can use this simple style for the Panel : <style type="text/css"> .ModalWindow { border: solid; border-width:3px; background:#f0f0f0; } </style> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   2- Create the view button (TargetControlID) as you know this contain the ID of the element that activates the modal popup: <asp:Button ID="btnView" runat="server" Text="View" /> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff;

color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000;

$get('<%=txtName.ClientID%>').focus();   });   $find('ModalPopupExtender1').add_hiding(function() { alert('add_hiding event fires'); $get('<%=txtName.ClientID%>').value = ""; $get('<%=txtPassword.ClientID%>').value = "";   }); }   </script> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em;

} .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   I’ve added the two alerts just to let you show when the event fires.   Hope this simple example show you the benefit and how to use these events.

  • Unexplained CPU and Disk activity spikes in SQL Server 2005

    - by Philip Goh
    Before I pose my question, please allow me to describe the situation. I have a database server, with a number of tables. Two of the biggest tables contain over 800k rows each. The majority of rows are less than 10k in size, though roughly 1 in 100 rows will be 1 MB but <4 MB. So out of the 1.6 million rows, about 16000 of them will be these large rows. The reason they are this big is because we're storing zip files binary blobs in the database, but I'm digressing. We have a service that runs constantly in the background, trimming 10 rows from each of these 2 tables. In the performance monitor graph above, these are the little bumps (red for CPU, green for disk queue). Once ever minute we get a large spike of CPU activity together with a jump in disk activity, indicated by the red arrow in the screenshot. I've run the SQL Server profiler, and there is nothing that jumps out as a candidate that would explain this spike. My suspicion is that this spike occurs when one of the large rows gets deleted. I've fed the results of the profiler into the tuning wizard, and I get no optimisation recommendations (i.e. I assume this means my database is indexed correctly for my current workload). I'm not overly worried as the server is coping fine in all circumstances, even under peak load. However, I would like to know if there is anything else I can do to find out what is causing this spike? Update: After investigating this some more, the CPU and disk usage spike was down to SQL server's automatic checkpoint. The database uses the simple recovery model, and this truncates the log file at each checkpoint. We can see this demonstrated in the following graph. As described on MSDN, the checkpoints will occur when the transaction log becomes 70% full and we are using the simple recovery model. This has been enlightening and I've definitely learned something!

  • Is there a blog tool with support for tagging posts, only displaying posts with certain combinations

    - by Philip
    What I want: A blog. I can tag posts, e.g. "A" or "B" or "all," and then you can either 1) click to only view posts tagged "A" or "all" or 2) even more ideally, I can set it so you automatically see posts tagged "A" or "all" when you log in. LaTeX support--I can type in LaTeX in the editor and it will show the math properly. No anonymous anything--must sign up and be logged in to view and comment Not as important, but convenient: Admin controls, e.g. detailed statistics, see who posts or views what when, control who posts / views, etc. Hosting: Ideally, if there's some software I can install on "my" own server, that would be ideal. But if we can't host it, it'd still be good to find some free (or maybe even paid) service elsewhere that would host the blog if it provided those tools. Any thoughts? I have no experience with this. Thanks!

  • Where should CentOS users get /usr/share/virtio-win/drivers for virt-v2v?

    - by Philip Durbin
    I need to migrate a number of virtual machines from VMware ESX to CentOS 6 KVM hypervisors. Ultimately, I wrote an RPM spec file that solved my problem at https://github.com/fasrc/virtio-win/blob/master/virtio-win.spec but I'm not sure if there's another RPM in base CentOS or EPEL (something standard) I should be using instead. Originally, I was getting this "No root device found in this operating system image" error when attemting to migrate a Window 2008 VM. . . [root@kvm01b ~]# virt-v2v -ic 'esx://my-vmware-hypervisor.example.com/' \ -os transferimages --network default my-vm virt-v2v: No root device found in this operating system image. . . . but I solved this with a simply yum install libguestfs-winsupport since the docs say: If you attempt to convert a virtual machine using NTFS without the libguestfs-winsupport package installed, the conversion will fail. Next I got an error about missing drivers for Windows 2008. . . [root@kvm01b ~]# virt-v2v -ic 'esx://my-vmware-hypervisor.example.com/' \ -os transferimages --network default my-vm my-vm_my-vm: 100% [====================================]D virt-v2v: Installation failed because the following files referenced in the configuration file are required, but missing: /usr/share/virtio-win/drivers/amd64/Win2008 . . . and I resolved this by grabbing an iso from Fedora at http://alt.fedoraproject.org/pub/alt/virtio-win/latest/ as recommended by http://www.linux-kvm.org/page/WindowsGuestDrivers/Download_Drivers and building an RPM from it with this spec file: https://github.com/fasrc/virtio-win/blob/master/virtio-win.spec Now, virt-v2v exits without error: [root@kvm01b ~]# virt-v2v -ic 'esx://my-vmware-hypervisor.example.com/' \ -os transferimages --network default my-vm my-vm_my-vm: 100% [====================================]D virt-v2v: my-vm configured with virtio drivers. [root@kvm01b ~]# Now, my question is, rather that the virtio-win RPM from the spec file I wrote, is there some other more standard RPM in base CentOS or EPEL that will resolve the error above? Here's a bit more detail about my setup: [root@kvm01b ~]# cat /etc/redhat-release CentOS release 6.2 (Final) [root@kvm01b ~]# rpm -q virt-v2v virt-v2v-0.8.3-5.el6.x86_64 See also Bug 605334 – VirtIO driver for windows does not show specific OS: Windows 7, Windows 2003

  • What are the implications of expanding an internal subnet mask?

    - by Philip
    Our network is currently working on a 192.168.0.x subnet, all controlled through DHCP, except for the few main servers who have hard-configured IP address settings. What would I kill if I changed the DHCP-published subnet mask from 255.255.255.0 to 255.255.0.0? The reason for doing this is not because we have a huge sudden influx of machines, but because I'd like to start partitioning specific devices into specific IP ranges (to be neat and tidy). For what its worth, I don' plan on changing the allocated DHCP address range, but rather want to move some of the reserved and excluded DHCP addresses out of the address pool. e.g. printers will be 192.168.2.x I will obviously need to change the subnet mask manually on my manually configured devices.

  • EC2 Filesystem / Files stored on the wrong partiton after launching new instance from AMI

    - by Philip Isaacs
    Today I set up a new EC2 Instance from and AMI I created from an older EC2 instance. When I launched the new instance I took the AMI that was on a small instance and launched with a medium instance. From what I can tell this is pretty standard stuff. But here's the stang part. According to AWS these are the differences Small Instance (Default) 1.7 GB of memory, 1 EC2 Compute Unit (1 virtual core with 1 EC2 Compute Unit), 160 GB of local instance storage, 32-bit or 64-bit platform Medium Instance 3.75 GB of memory, 2 EC2 Compute Units (1 virtual core with 2 EC2 Compute Units each), 410 GB of local instance storage, 32-bit or 64-bit platform Okay now here's where I'm having an issue. I when I log into the new bigger instance it still reports only having 1.7 GB of ram. The other strange part is that all my old partitions are still their in the same configurations. I see a new larger partition /mnt which is essential empty. Filesystem Size Used Avail Use% Mounted on /dev/sda1 7.9G 5.9G 1.6G 79% / none 846M 120K 846M 1% /dev none 879M 0 879M 0% /dev/shm none 879M 76K 878M 1% /var/run none 879M 0 879M 0% /var/lock none 879M 0 879M 0% /lib/init/rw /dev/sda2 335G 195M 318G 1% /mnt /dev/sdf 16G 9.9G 5.1G 67% /var2 This EC2 is a web server and I was serving files off the /var2 directory but for some reason the instance is storing everything on / Okay here's what I'd like to do. Move all my website files to /mnt and have the web server point to that. Any suggestions? If it helps here is what my fstab looks like as well. root@myserver:/var# mount -l /dev/sda1 on / type ext3 (rw) [cloudimg-rootfs] proc on /proc type proc (rw,noexec,nosuid,nodev) none on /sys type sysfs (rw,noexec,nosuid,nodev) none on /sys/kernel/debug type debugfs (rw) none on /sys/kernel/security type securityfs (rw) none on /dev type devtmpfs (rw,mode=0755) none on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620) none on /dev/shm type tmpfs (rw,nosuid,nodev) none on /var/run type tmpfs (rw,nosuid,mode=0755) none on /var/lock type tmpfs (rw,noexec,nosuid,nodev) none on /lib/init/rw type tmpfs (rw,nosuid,mode=0755) /dev/sda2 on /mnt type ext3 (rw) /dev/sdf on /var2 type ext4 (rw,noatime) I hope this question makes sense. Basically i want my old files on this new partition. Thanks in advance

  • What Is the Keyboard Shortcut for Moving to Last Message in Mac OS X Mail.app?

    - by Philip Durbin
    I'm on Mac OS X 10.5.8 (Leopard). In Mail, I have the first message in my Inbox selected and I'm trying to navigate to the last message using my keyboard. In Thunderbird, I just hit the End key, which for me is "Function-right arrow" because I'm on a MacBook Pro. In Mail, with the first message selected, if I hit "Function-right arrow" (i.e. End), the scroll bar moves down, allowing me to see the messages at the bottom of the list, but the first message at the top of the list is still selected. What I want is for the last message to be selected. I've tried lots of key combinations and searched for the answer but haven't been able to find it. Please help. I posted this originally at discussions.apple.com but the only advice I received was to file a bug with Apple, which I did.

  • Sending cron output to a file with a timestamp in its name

    - by Philip Morton
    I have a crontab like this on a LAMP setup: 0 0 * * * /some/path/to/a/file.php > $HOME/cron.log 2>&1 This writes the output of the file to cron.log. However, when it runs again, it overwrites whatever was previously in the file. How can I get cron to output to a file with a timestamp in its filename? An example filename would be something like this: 2010-02-26-000000-cron.log I don't really care about the format, as long as it has a timestamp of some kind. Thanks in advance.
