  • Manage Your Amazon S3 Account with CloudBerry Explorer

    - by Mysticgeek
    If you have an Amazon S3 account you’re using to backup your data, you might want an easy way to manage it. CloudBerry Explorer is a free app that runs on your desktop an provides an easy way to manage your S3 account. Installation and Setup Just download and install the application with the defaults. When the application launches you’ll be prompted to enter in your username and email to get a registration key. Or you can continue on by clicking Register later. Now you will want to set up your Amazon S3 account. Click on File \ Amazon S3 Accounts. Double-click on the New Account icon.   Next enter in your Amazon account Access and Secret keys, select SSL if you want, then click the Test Connection button. Provided everything was entered correctly, you’ll see the Connection Success screen, just close out of it. Browse and Manage files Once you have your account setup through the Explorer, you can start viewing and managing your files on S3. The left pane shows your S3 buckets and stored files, while the right side shows your local computer. This allows you to manage your files in your Amazon S3 buckets directly from your desktop! It’s very easy to use, and you can drag and drop files from your computer to the S3 account or vice versa. There is also the ability to transfer files between Amazon S3 accounts from within the explorer. Go into Tools and Content Types and you can control the file types by adding, removing, or editing them. If you end up messing something up along the lines, you can always select Reset to defaults and everything will be back to normal. There is a multiple tabbed view so you can easily keep track of your different accounts and local machine. It allows the ability to create new storage buckets directly in the Explorer. Or you can delete buckets as well… Different actions can be accessed from the toolbars or by right-clicking and selecting from the context menu. Here we see a cool option that lets you move your data inside Amazon S3. It is faster and doesn’t cost money by moving the files to your computer first, then to another account. However, if you want data moved to your local machine first, you have that option as well.   Not all features are available in the free version, and if it’s not, you’ll be prompted to purchase a license for the Pro version. We will have a comprehensive review of the Pro version in the near future.    If you ever need help with CloudBerry Explorer, go to Tools \ Diagnostics. It will run a quick diagnostics check and you can send the information to the CloudBerry team for assistance. Delete Files from Amazon S3 To delete a file from you Amazon S3 account, simply highlight the files or folder you want to get rid of then click Delete on the toolbar. You can also right-click the file and select Delete from the Context Menu. Click Yes to the confirmation dialog box… Then you can watch the progress as your files are deleted in the bottom section of the explorer. Conclusion CloudBerry Explorer free version has several neat features that will allow you easy and basic control over you Amazon S3 account. The free version may be enough for basic users, but power users will want to upgrade to the pro version, as it includes a lot more features. Using the free version allows you to get a feel for what CloudBerry Explorer has to offer, and is a good starting point. Keep in mind that Amazon S3 is introducing Reduced Redundancy Storage which will lower the price of data stored. The price drops from $0.15 per GB to only $0.10 per GB.

  • How to restore Windows 7 MBR without a CD

    - by Brandon Bertelsen
    I have been playing with Ubuntu for a few weeks now, and I'd like to revert my computer back to it's original - factory - defaults. On the computer I have a recovery partition (it's a netbook). I went through the process of recovery and everything seemed fine. However, when I restart the computer I'm presented with grub rescue > Now, my understanding is that when I installed Ubuntu "side by side" it replaced the MBR or something like it, with GRUB. I've read on a slew of forums, that I need to use a Windows Recovery Disk. Here are my issues: a) I don't have a recovery disk, I have a recovery partition - it's a netbook. b) I don't have an external cd drive. What I do have is a USB key that has about 1gb of space on it. Thanks in advance.

  • set installer background / not able to run early_command in custom preseed file (precise)

    - by user73093
    I have a custom preseed file for a Precise Live CD (which is well loaded on boot, I checked syslog for that). My initial problem is that when booting in install mode (default behavior for a Live CD), ubiquity runs X with a default wallpaper which is hardcoded to /usr/share/backgrounds/warty-final-ubuntu.png in Ubiquity code. So my idea was to run early_command (https://help.ubuntu.com/12.04/installation-guide/i386/preseed-advanced.html) to copy my custom wallpaper over /usr/share/backgrounds/warty-final-ubuntu.png. Assuming my custom wallpaper allready resides on the rootfs in /usr/share/backgrounds. But... It seems the early_command never runs (and I'm sure the preseed file is taken into account) Here is what I have added to my preseed file: d-i preseed/early_command string cp /usr/share/backgrounds/mywallpaper-defaults.jpg /usr/share/backgrounds/warty-final-ubuntu.png Even this one is never run: d-i preseed/early_command string /usr/bin/touch /tmp/testearly Thanks for helping !!

    I need to tweak my Dell XPS 13z SSD for maximum performance and life cycle than I read the solutions explained here, but it is for 11.10 and my fstab is different. For now my fstab is looks like this: proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sda1 during installation UUID=abf5ce9e-bdb7-4b2f-a7bd-bbd9efa72a98 / ext4 errors=remount-ro 0 1 # /home was on /dev/sda2 during installation UUID=491427b2-7482-4483-b6eb-7c564b991aff /home ext4 defaults 0 2 # swap was on /dev/sda3 during installation #UUID=7551000d-e708-4e0f-9fd2-9f93119f63fb none swap sw 0 0 /dev/mapper/cryptswap1 none swap sw 0 0 tmpfs /tmp tmpfs mode=1777 And my rc.local is looks like this: echo noop > /sys/block/sda/queue/scheduler echo deadline > /sys/block/sda/queue/scheduler echo 1 > /sys/block/sda/queue/iosched/fifo_batch exit 0 Do you have any suggestions, what should I do?

  • Telerik Releases a new Visual Entity Designer

    Love LINQ to SQL but are concerned that it is a second class citizen? Need to connect to more databases other than SQL Server? Think that the Entity Framework is too complex? Want a domain model designer for data access that is easy, yet powerful? Then the Telerik Visual Entity Designer is for you. Built on top of Telerik OpenAccess ORM, a very mature and robust product, Teleriks Visual Entity Designer is a new way to build your domain model that is very powerful and also real easy to use. How easy? Ill show you here. First Look: Using the Telerik Visual Entity Designer To get started, you need to install the Telerik OpenAccess ORM Q1 release for Visual Studio 2008 or 2010. You dont need to use any of the Telerik OpenAccess wizards, designers, or using statements. Just right click on your project and select Add|New Item from the context menu. Choose Telerik OpenAccess Domain Model from the Visual Studio project templates. (Note to existing OpenAccess users, dont run the Enable ORM wizard or any other OpenAccess menu unless you are building OpenAccess Entities.) You will then have to specify the database backend (SQL Server, SQL Azure, Oracle, MySQL, etc) and connection. After you establish your connection, select the database objects you want to add to your domain model. You can also name your model, by default it will be NameofyourdatabaseEntityDiagrams. You can click finish here if you are comfortable, or tweak some advanced settings. Many users of domain models like to add prefixes and suffixes to classes, fields, and properties as well as handle pluralization. I personally accept the defaults, however, I hate how DBAs force underscores on me, so I click on the option to remove them. You can also tweak your namespace, mapping options, and define your own code generation template to gain further control over the outputted code. This is a very powerful feature, but for now, I will just accept the defaults.   When we click finish, you can see your domain model as a file with the .rlinq extension in the Solution Explorer. You can also bring up the visual designer to view or further tweak your model by double clicking on the model in the Solution Explorer.  Time to use the model! Writing a LINQ Query Programming against the domain model is very simple using LINQ. Just set a reference to the model (line 12 of the code below) and write a standard LINQ statement (lines 14-16).  (OpenAccess users: notice the you dont need any using statements for OpenAccess or an IObjectScope, just raw LINQ against your model.) 1: using System; 2: using System.Linq; 3: //no need for anOpenAccess using statement 4:   5: namespace ConsoleApplication3 6: { 7: class Program 8: { 9: static void Main(string[] args) 10: { 11: //a reference tothe data context 12: NorthwindEntityDiagrams dat = new NorthwindEntityDiagrams(); 13: //LINQ Statement 14: var result = from c in dat.Customers 15: where c.Country == "Germany" 16: select c; 17:   18: //Print out the company name 19: foreach (var cust in result) 20: { 21: Console.WriteLine("CompanyName: " + cust.CompanyName); 22: } 23: //keep the consolewindow open 24: Console.Read(); 25: } 26: } 27: } .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; } Lines 19-24 loop through the result of our LINQ query and displays the results. Thats it! All of the super powerful features of OpenAccess are available to you to further enhance your experience, however, in most cases this is all you need. In future posts I will show how to use the Visual Designer with some other scenarios. Stay tuned. Enjoy!

  • Swap partition not recognized (The disk drive with UUID=... is not ready yet or not present)

    - by ladaghini
    I think I had an encrypted swap partition, because I chose to encrypt my home directory during the installation. I believe that's what the line with /dev/mapper/cryptswap1 ... in my /etc/fstab is all about. I did something to bork my swap because on the next boot, I got a message (paraphrased): The disk drive for /dev/mapper/cryptswap1 is not ready yet or not present. Wait to continue. Press S to skip or M to manually recover. (As a side note, pressing S or M seemed to do nothing different from just waiting.) Here's what I've tried: This tutorial on how to fix the swap partition not mounting. However, in the above, the mkswap command fails because the device is busy. So I booted from a live USB, ran GParted to reformat the swap partition (which showed up as an unknown fs type), and chrooted into the broken system to try that tutorial again. I also adjusted /etc/initramfs-tools/conf.d/resume and /etc/fstab to reflect the new UUID generated from formatting the partition as a swap. That still didn't work; instead of /dev/mapper/cryptswap1 not present, "The disk drive with UUID=[swap partition's UUID] is not ready yet or not present..." So I decided to start afresh as though I never had created a swap partition in the first place. From the Live USB, I deleted the swap partition altogether (which, again showed up in GParted as an unknown fs type), removed the swap and cryptswap entries in /etc/fstab as well as removed /etc/initramfs-tools/conf.d/resume and /etc/crypttab. At this point the main system shouldn't be considered broken because there is no swap partition and no instructions to mount one, right? I didn't get any errors during startup. I followed the same instructions to create and encrypt the swap partition, starting with creating a partition for the swap, though I think fdisk said a reboot was necessary to see changes. I was confident the 3rd process above would work, but the problem yet persists. Some relevant info (/dev/sda8 is the swap partition): /etc/fstab file: # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sda6 during installation UUID=4c11e82c-5fe9-49d5-92d9-cdaa6865c991 / ext4 errors=remount-ro 0 1 # /boot was on /dev/sda5 during installation UUID=4031413e-e89f-49a9-b54c-e887286bb15e /boot ext4 defaults 0 2 # /home was on /dev/sda7 during installation UUID=d5bbfc6f-482a-464e-9f26-fd213230ae84 /home ext4 defaults 0 2 # swap was on /dev/sda8 during installation UUID=5da2c720-8787-4332-9317-7d96cf1e9b80 none swap sw 0 0 /dev/mapper/cryptswap1 none swap sw 0 0 output of sudo mount: /dev/sda6 on / type ext4 (rw,errors=remount-ro) proc on /proc type proc (rw,noexec,nosuid,nodev) sysfs on /sys type sysfs (rw,noexec,nosuid,nodev) none on /sys/fs/fuse/connections type fusectl (rw) none on /sys/kernel/debug type debugfs (rw) none on /sys/kernel/security type securityfs (rw) udev on /dev type devtmpfs (rw,mode=0755) devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620) tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755) none on /run/lock type tmpfs (rw,noexec,nosuid,nodev,size=5242880) none on /run/shm type tmpfs (rw,nosuid,nodev) /dev/sda5 on /boot type ext4 (rw) /dev/sda7 on /home type ext4 (rw) /home/undisclosed/.Private on /home/undisclosed type ecryptfs (ecryptfs_check_dev_ruid,ecryptfs_cipher=aes,ecryptfs_key_bytes=16,ecryptfs_unlink_sigs,ecryptfs_sig=cbae1771abd34009,ecryptfs_fnek_sig=7cefe2f59aab8e58) gvfs-fuse-daemon on /home/undisclosed/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=undisclosed) output of sudo blkid (note that /dev/sda8 is missing): /dev/sda1: LABEL="SYSTEM" UUID="960490E80490CC9D" TYPE="ntfs" /dev/sda2: UUID="D4043140043126C0" TYPE="ntfs" /dev/sda3: LABEL="Shared" UUID="80F613E1F613D5EE" TYPE="ntfs" /dev/sda5: UUID="4031413e-e89f-49a9-b54c-e887286bb15e" TYPE="ext4" /dev/sda6: UUID="4c11e82c-5fe9-49d5-92d9-cdaa6865c991" TYPE="ext4" /dev/sda7: UUID="d5bbfc6f-482a-464e-9f26-fd213230ae84" TYPE="ext4" /dev/mapper/cryptswap1: UUID="41fa147a-3e2c-4e61-b29b-3f240fffbba0" TYPE="swap" output of sudo fdisk -l: Disk /dev/mapper/cryptswap1 doesn't contain a valid partition table Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xdec3fed2 Device Boot Start End Blocks Id System /dev/sda1 * 2048 409599 203776 7 HPFS/NTFS/exFAT /dev/sda2 409600 210135039 104862720 7 HPFS/NTFS/exFAT /dev/sda3 210135040 415422463 102643712 7 HPFS/NTFS/exFAT /dev/sda4 415424510 625141759 104858625 5 Extended /dev/sda5 415424512 415922175 248832 83 Linux /dev/sda6 415924224 515921919 49998848 83 Linux /dev/sda7 515923968 621389823 52732928 83 Linux /dev/sda8 621391872 625141759 1874944 82 Linux swap / Solaris Disk /dev/mapper/cryptswap1: 1919 MB, 1919942656 bytes 255 heads, 63 sectors/track, 233 cylinders, total 3749888 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xaf5321b5 /etc/initramfs-tools/conf.d/resume file: RESUME=UUID=5da2c720-8787-4332-9317-7d96cf1e9b80 /etc/crypttab file: cryptswap1 /dev/sda8 /dev/urandom swap,cipher=aes-cbc-essiv:sha256 output of sudo swapon -as: Filename Type Size Used Priority /dev/mapper/cryptswap1 partition 1874940 0 -1 output of sudo free -m: total used free shared buffers cached Mem: 1476 1296 179 0 35 671 -/+ buffers/cache: 590 886 Swap: 1830 0 1830 So, how can this be fixed?

  • Smartassembly 5: it lives! Early Access builds now available

    - by Bart Read
    I'm pleased to announce that, late last week, we put out the first early access build for Smartassembly 5, Red Gate's fantastic code protection and error reporting tool, which we acquired last September. You can download it via: http://www.red-gate.com/messageboard/viewforum.php?f=116 It's obviously pretty early days, so please do not try to use this to protect a production application, but we've already done a lot of work in some key areas: We're simplifying and streamlining the licensing model (you won't see this yet, but a lot of the work on this has already been done). We've improved usability of the product, with a better menu, reordering of project settings, and better defaults. We've also fixed a load of bugs, which I'll let Alex blog about in more detail. On a slightly more trivial level, the curly braces are also no more. Over the coming weeks, we'll be adding more improvements, and starting usability tests. If you're interested in getting involved in the latter, please drop an email to [email protected].

  • Permanently mounting Windows' NTFS partition, fully enabled

    - by Bart van Heukelom
    I'm transforming a Windows 7 PC into a dual boot system with Ubuntu 10.10. Following other questions on this site, I've mounted my Windows drive by adding this to fstab UUID=blabla /windows ntfs users,defaults,umask=000 0 0 It appears to work well, I can read and write, but it appears to be a bit crippled still. When I tried to update an SVN working copy with RabbitVCS, it complained that it couldn't write to a temporary file inside the working copy, even though the permissions are all on 0777 inside /windows (by default, I haven't done that manually). It even corrupted that working copy :( It works when I use the command line SVN client with sudo, but that's hardly user friendly.

  • What are the appropriate mount options for a shared NTFS partition on an SSD in a dual boot Ubuntu/Windows setup?

    - by Andreas Jonsson
    I have Ubuntu 13.10 and Windows 7 installed in dual boot on a single SSD. In addition they share an NTFS partition where I put all my data and documents. What is the optimal way to mount this NTFS partition in /etc/fstab (considering performance and minimizing wear of the SSD)? Similar questions have been asked, but I could not find answers to this particular scenario. As I understand it, the mount option 'discard' is not supported for NTFS and so should not be used (although it is recommended here). Another often quoted mount option is 'noatime'. I use it for my ext4 partitions. Does it apply to NTFS? My current /etc/fstab line is: UUID=XXXXXXXXXXXXXXXX /dos ntfs defaults,nls=utf8,uid=1000,gid=1000 0 0

  • High contrast theme Firefox problem

    - by user87239
    I am using the high contrast inverse theme in 12.04 as I am visually impaired. This generally works great but causes a problem in Firefox as entered text e.g into a Google search is white. As the text background is also white you cannot see what you are typing. I have read through a good thirty websites with similar issues but thus far nothing works. I have tried all the settings in Firefox like un-checking "Use System Defaults" as well as manually telling Firefox what colours to use and these setting have absolutely no effect on anything.

  • phpBB3 antispam: mod for "patrolling" the forum?

    - by STATUS_ACCESS_DENIED
    I've been working on various antispam measure in a phpBB3-based forum I host. Now I was thinking of an extension/mod that ties in with editing of posts (and later perhaps signatures/profiles) in that new text or edited text defaults to something like "not patrolled" and moderators could then in a special queue review text that contains links or similar item (based on heuristics). Now the question: does such a mod exist (I didn't find one)? If it does exist and anyone has used it (or them), please include your experiences with it in the answer.

  • Disable auto-mount for particular partitions on usb drives

    - by nealmcb
    I have a big USB disk with 3 partitions: one for backup and two other bootable ones for installing and testing new distros. I want the backup partition automounted on boot. But I don't want the two test partitions automounted. Despite my use of "noauto" in /etc/fstab, something (gnome?) seems to be mounting them when I plug the drive it. LABEL=mybook /srv/backup ext4 defaults 0 2 LABEL=mybook-root /media/mybook-root ext4 user,noauto 0 2 LABEL=mybook-spare /media/mybook-spare ext4 user,noauto 0 2 In previous Ubuntu distributions it seems that it was possible to configure gnome so it would avoid mounting particular partitions on removable drives like USB: gnome-mount --write-settings --mount-options noauto --device /dev/sda1 This is no longer available in Lucid (when did it go away?) Is there another way to do this now?

  • How to completely integrate Nemo with Ubuntu?

    - by user74660
    I have installed Nemo (a fork of Nautilus created by the Linux Mint Team) in my Ubuntu 12.04.1 LTS with Gnome Shell 3.4.2. I followed the instructions here (https://help.ubuntu.com/community/DefaultFileManager), changing the "inode" and "x-directory" in the file "defaults.list", to make Nemo my default file manager. Now everything works perfectly, except for one thing: opening folders from desktop. I have set the option "Have file manager handle the desktop" on. Cool. The problem is that the desktop seems to be handled by Nautilus only, even if I have set another file manager as default. Every time I double click a folder on the desktop, it is opened by Nautilus, not Nemo. Please, does anybody know how to fix this? Thanks for your time. :)

  • C#/.NET Little Wonders: Getting Caller Information

    - by James Michael Hare
    Originally posted on: http://geekswithblogs.net/BlackRabbitCoder/archive/2013/07/25/c.net-little-wonders-getting-caller-information.aspx Once again, in this series of posts I look at the parts of the .NET Framework that may seem trivial, but can help improve your code by making it easier to write and maintain. The index of all my past little wonders posts can be found here. There are times when it is desirable to know who called the method or property you are currently executing.  Some applications of this could include logging libraries, or possibly even something more advanced that may server up different objects depending on who called the method. In the past, we mostly relied on the System.Diagnostics namespace and its classes such as StackTrace and StackFrame to see who our caller was, but now in C# 5, we can also get much of this data at compile-time. Determining the caller using the stack One of the ways of doing this is to examine the call stack.  The classes that allow you to examine the call stack have been around for a long time and can give you a very deep view of the calling chain all the way back to the beginning for the thread that has called you. You can get caller information by either instantiating the StackTrace class (which will give you the complete stack trace, much like you see when an exception is generated), or by using StackFrame which gets a single frame of the stack trace.  Both involve examining the call stack, which is a non-trivial task, so care should be done not to do this in a performance-intensive situation. For our simple example let's say we are going to recreate the wheel and construct our own logging framework.  Perhaps we wish to create a simple method Log which will log the string-ified form of an object and some information about the caller.  We could easily do this as follows: 1: static void Log(object message) 2: { 3: // frame 1, true for source info 4: StackFrame frame = new StackFrame(1, true); 5: var method = frame.GetMethod(); 6: var fileName = frame.GetFileName(); 7: var lineNumber = frame.GetFileLineNumber(); 8: 9: // we'll just use a simple Console write for now 10: Console.WriteLine("{0}({1}):{2} - {3}", 11: fileName, lineNumber, method.Name, message); 12: } So, what we are doing here is grabbing the 2nd stack frame (the 1st is our current method) using a 2nd argument of true to specify we want source information (if available) and then taking the information from the frame.  This works fine, and if we tested it out by calling from a file such as this: 1: // File c:\projects\test\CallerInfo\CallerInfo.cs 2:  3: public class CallerInfo 4: { 5: Log("Hello Logger!"); 6: } We'd see this: 1: c:\projects\test\CallerInfo\CallerInfo.cs(5):Main - Hello Logger! This works well, and in fact CallStack and StackFrame are still the best ways to examine deeper into the call stack.  But if you only want to get information on the caller of your method, there is another option… Determining the caller at compile-time In C# 5 (.NET 4.5) they added some attributes that can be supplied to optional parameters on a method to receive caller information.  These attributes can only be applied to methods with optional parameters with explicit defaults.  Then, as the compiler determines who is calling your method with these attributes, it will fill in the values at compile-time. These are the currently supported attributes available in the  System.Runtime.CompilerServices namespace": CallerFilePathAttribute – The path and name of the file that is calling your method. CallerLineNumberAttribute – The line number in the file where your method is being called. CallerMemberName – The member that is calling your method. So let’s take a look at how our Log method would look using these attributes instead: 1: static int Log(object message, 2: [CallerMemberName] string memberName = "", 3: [CallerFilePath] string fileName = "", 4: [CallerLineNumber] int lineNumber = 0) 5: { 6: // we'll just use a simple Console write for now 7: Console.WriteLine("{0}({1}):{2} - {3}", 8: fileName, lineNumber, memberName, message); 9: } Again, calling this from our sample Main would give us the same result: 1: c:\projects\test\CallerInfo\CallerInfo.cs(5):Main - Hello Logger! However, though this seems the same, there are a few key differences. First of all, there are only 3 supported attributes (at this time) that give you the file path, line number, and calling member.  Thus, it does not give you as rich of detail as a StackFrame (which can give you the calling type as well and deeper frames, for example).  Also, these are supported through optional parameters, which means we could call our new Log method like this: 1: // They're defaults, why not fill 'em in 2: Log("My message.", "Some member", "Some file", -13); In addition, since these attributes require optional parameters, they cannot be used in properties, only in methods. These caveats aside, they do let you get similar information inside of methods at a much greater speed!  How much greater?  Well lets crank through 1,000,000 iterations of each.  instead of logging to console, I’ll return the formatted string length of each.  Doing this, we get: 1: Time for 1,000,000 iterations with StackTrace: 5096 ms 2: Time for 1,000,000 iterations with Attributes: 196 ms So you see, using the attributes is much, much faster!  Nearly 25x faster in fact.  Summary There are a few ways to get caller information for a method.  The StackFrame allows you to get a comprehensive set of information spanning the whole call stack, but at a heavier cost.  On the other hand, the attributes allow you to quickly get at caller information baked in at compile-time, but to do so you need to create optional parameters in your methods to support it.

  • 50-synaptics.conf options not working

    - by djeikyb
    How does Ubuntu come up with the default synaptics settings? I've got Ubuntu Netbook 10.10 installed on an Eeepc 900. Out of the box TapButton2 was set to 3, and TapButton3 was set to 2. I have several custom synaptics settings I want as system wide defaults. Right now I use a script with synclient commands I have to run every boot or wake. Pita. It used to be everything went in xorg.conf..which no longer exists. I'm trying to learn the new way, which is apparently conf files at /usr/share/X11/xorg.conf.d. I edited 50-synaptics.conf to look like: Section "InputClass" Identifier "touchpad catchall" Driver "synaptics" MatchIsTouchpad "on" MatchDevicePath "/dev/input/event*" Option "LockedDrags" "1" Option "TapButton2" "2" Option "TapButton3" "3" EndSection But my next X session (startx -- :2) doesn't have the options configured.

  • How to close lid without triggering standby one time only

    - by Ian Mackinnon
    Related: How can I tell Ubuntu to do nothing when I close my laptop lid? I have my laptop set to activate standby when I close the lid. I want to keep this as the default for both battery and AC power. But occasionally I want to close the lid without triggering standby (eg. while just listening to audio). Is there someway I can tell Ubuntu, "I'm going to close the lid now. Don't stand by this time", without altering the defaults (because I almost always forget to change them back).

  • Prevent APT from overwriting JCE jars

    - by Doc
    My server runs a Java application that requires I replace a few java library files with ones I downloaded on my own. This has to do with JCE security extensions and isn't really relevant to my question. I've found that these library files tend to get overwritten by apt when it later updates my java package. Is there a apt-friendly way of masking these specific files so apt won't touch them? Potential Solutions I'm considering just removing the write flag from the files, though I'm expecting this will cause apt to spew its guts everywhere when it later tries to overwrite them? Perhaps there's a java custom library directory I don't know of, where I can park my files and they'll be loaded instead of the package's defaults? The last-resort option I'm considering is writing a cron job to periodically replace the files with my versions. I hate this option.

  • A very useful custom component

    - by Kevin Smith
    Whenever I am debugging a problem in WebCenter Content (WCC) I often find it useful to see the contents of the internal data binder used by WCC when executing a service. I want to know the value of all parameters passed in by the caller, either a user in the web GUI or from an application calling the service via RIDC or web services. I also want to the know the value of binder variables calculated by WCC as it processes a service. What defaults has it applied based on configuration settings or profile rules? What values has it derived based on the user input? To help with this I created a  component that uses a java filter to dump out the contents of the internal data binder to the WCC trace file. It dumps the binder contents using the toString() method. You can register this filter code using many different filter hooks to see how the binder is updated as WCC processes the service. By default, it uses the validateStandard filter hook which is useful during a CHECKIN service. It uses the system trace section, so make sure that trace section is enabled before looking for the output from this component. Here is some sample output>system/6    10.09 09:57:40.648    IdcServer-1    filter: postParseDataForServiceRequest, binder start -- system/6    10.09 09:57:40.698    IdcServer-1    *** LocalData *** system/6    10.09 09:57:40.698    IdcServer-1    (10 keys + 0 defaults) system/6    10.09 09:57:40.698    IdcServer-1    ClientEncoding=UTF-8 system/6    10.09 09:57:40.698    IdcServer-1    IdcService=CHECKIN_UNIVERSAL system/6    10.09 09:57:40.698    IdcServer-1    NoHttpHeaders=0 system/6    10.09 09:57:40.698    IdcServer-1    UserDateFormat=iso8601 system/6    10.09 09:57:40.698    IdcServer-1    UserTimeZone=UTC system/6    10.09 09:57:40.698    IdcServer-1    dDocTitle=Check in from RIDC using Framework Folder system/6    10.09 09:57:40.698    IdcServer-1    dDocType=Document system/6    10.09 09:57:40.698    IdcServer-1    dSecurityGroup=Public system/6    10.09 09:57:40.698    IdcServer-1    parentFolderPath=/folder1/folder2 system/6    10.09 09:57:40.698    IdcServer-1    primaryFile=testfile5.bin     system/6    10.09 09:57:40.698    IdcServer-1    ***  RESULT SETS  ***>system/6    10.09 09:57:40.698    IdcServer-1    binder end -------------------------------------------- See the readme included in the component for more details.

When the submit image is pressed, the URL changes to the PHP file, but it displays a blank page. After display errors activated: ini_set('display_errors',1); ini_set('display_startup_errors',1); error_reporting(-1) FF/IE display blank page and email isn't sent, Chrome sends the email and displays this: Strict Standards: Non-static method Mail::factory() should not be called statically in /var/www/vhosts/[site url]/httpdocs/lista2.php on line 33 Strict Standards: Non-static method PEAR::isError() should not be called statically, assuming $this from incompatible context in /usr/share/php/Mail/smtp.php , dont know if it helps So, what is causing the email to be sent on chrome and not on FF or IE?

  • Which Compiz plugins can I safely disable?

    - by Sheldno
    On 11.10, which Compiz plugins are enabled by default? I.e. I should leave them enabled for some particular reason. I've imported my Compiz settings from my previous install and so I can't tell. I'd like to disable all unnecessary plugins because I've noticed the potential for interference or performance issues. I don't think I can trust the CCSM feature "Reset to defaults" because when I use it I need to run unity --reset afterwards in order for my desktop to work again (implying that the default values it resets to are not the values that Ubuntu/Unity requires).
