  • Python: Closing a for loop by reading stdout

    - by user1732102
    import os dictionaryfile = "/root/john.txt" pgpencryptedfile = "helloworld.txt.gpg" array = open(dictionaryfile).readlines() for x in array: x = x.rstrip('\n') newstring = "echo " + x + " | gpg --passphrase-fd 0 " + pgpencryptedfile os.popen(newstring) I need to create something inside the for loop that will read gpg's output. When gpg outputs this string gpg: WARNING: message was not integrity protected, I need the loop to close and print Success! How can I do this, and what is the reasoning behind it? Thanks Everyone!

  • nikto probe warning messages

    - by julio
    Hi-- I have a pretty standard VPS running Ubuntu 8.1, Apache 2.2, PHP 5 etc. -- standard Lamp stack. I am using suhosin and have tried my best to plug the obvious stuff, since I'm the only user-- there's no SSH access except via pubkey on a non-standard port, there's no root access by SSH, no FTP server running, iptables is set to discard anything outside of basically port 80 or my SSH port (there's no mail server or anything else). However, I've still been compromised (not badly as far as I can tell) probably by a SQL injection. I've locked down the SQL user (there's only one outside of root, and he's got limited priv, no file etc.) So I ran nikto to see what I'm doing wrong, and there's a list of things I've never seen, and can't find using "find" or any other method I'm aware of.

  • Memcached Lagging

    - by Brad Dwyer
    Let me preface this by saying that this is a followup question to this topic. That was "solved" by switching from Solaris (SmartOS) to Ubuntu for the memcached server. Now we've multiplied load by about 5x and are running into problems again. We are running a site that is doing about 1000 requests/minute, each request hits Memcached with approximately 3 reads and 1 write. So load is approximately 65 requests per second. Total data in the cache is about 37M, and each key contains a very small amount of data (a JSON-encoded array of integers amounting to less than 1K). We have setup a benchmarking script on these pages and fed the data into StatsD for logging. The problem is that there are spikes where Memcached takes a very long time to respond. These do not appear to correlate with spikes in traffic. What could be causing these spikes? Why would memcached take over a second to reply? We just booted up a second server to put in the pool and it didn't make any noticeable difference in the frequency or severity of the spikes. This is the output of getStats() on the servers: Array ( [-----------] => Array ( [pid] => 1364 [uptime] => 3715684 [threads] => 4 [time] => 1336596719 [pointer_size] => 64 [rusage_user_seconds] => 7924 [rusage_user_microseconds] => 170000 [rusage_system_seconds] => 187214 [rusage_system_microseconds] => 190000 [curr_items] => 12578 [total_items] => 53516300 [limit_maxbytes] => 943718400 [curr_connections] => 14 [total_connections] => 72550117 [connection_structures] => 165 [bytes] => 2616068 [cmd_get] => 450388258 [cmd_set] => 53493365 [get_hits] => 450388258 [get_misses] => 2244297 [evictions] => 0 [bytes_read] => 2138744916 [bytes_written] => 745275216 [version] => 1.4.2 ) [-----------:11211] => Array ( [pid] => 8099 [uptime] => 4687 [threads] => 4 [time] => 1336596719 [pointer_size] => 64 [rusage_user_seconds] => 7 [rusage_user_microseconds] => 170000 [rusage_system_seconds] => 290 [rusage_system_microseconds] => 990000 [curr_items] => 2384 [total_items] => 225964 [limit_maxbytes] => 943718400 [curr_connections] => 7 [total_connections] => 588097 [connection_structures] => 91 [bytes] => 562641 [cmd_get] => 1012562 [cmd_set] => 225778 [get_hits] => 1012562 [get_misses] => 125161 [evictions] => 0 [bytes_read] => 91270698 [bytes_written] => 350071516 [version] => 1.4.2 ) ) Edit: Here is the result of a set and retrieve of 10,000 values.

  • Automatically starting svnserve on Snow Leopard

    - by Cleggy
    Note: I originally asked this question on Server Fault (http://serverfault.com/questions/148052/automatically-starting-svnserve-on-snow-leopard), but I thought this may be a more appropriate place to ask. I have installed Subversion onto my iMac running Snow Leopard, but am having trouble getting svnserve to start up automatically. As I understand it (I'm still fairly green with OSX), the best way to do that is to utilize launchd. To that end, I have created the following .plist file in the /Library/LaunchDaemons folder. If I use launchctl to execute this file, svnserve starts as expected, but it doesn't automatically start when the system starts up or I log in. <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Disabled</key> <false/> <key>Label</key> <string>org.tigris.subversion.svnserve</string> <key>UserName</key> <string>Dave</string> <key>ProgramArguments</key> <array> <string>/opt/subversion/bin/svnserve</string> <string>--inetd</string> <string>--root=/Users/Shared/SVNrep</string> </array> <key>ServiceDescription</key> <string>Subversion Standalone Server</string> <key>Sockets</key> <dict> <key>Listeners</key> <array> <dict> <key>SockFamily</key> <string>IPv4</string> <key>SockServiceName</key> <string>svn</string> <key>SockType</key> <string>stream</string> </dict> <dict> <key>SockFamily</key> <string>IPv6</string> <key>SockServiceName</key> <string>svn</string> <key>SockType</key> <string>stream</string> </dict> </array> </dict> <key>inetdCompatibility</key> <dict> <key>Wait</key> <false/> </dict> </dict> </plist> I have tried many different configs in the .plist, including auto-starting, simplifying the listeners section, removing dependence on inetd, but they all show the same symptom. The files work when started using launchctl load, but do not automatically start up svnserve if the iMac is rebooted. If anyone here could provide any suggestions as to how to get this to work, I'd really appreciate it.

  • My computer freezes irregurarly

    - by Manhim
    My computer started to freeze at irregular times for 3 weeks now. What happens My computer freezes, the video stops. (No graphic glitches, it just stops) Sound keeps playing up to some time (Usually 10-30 seconds) then stops playing. Sometimes, randomly, the screen on my G-15 keyboard flickers and I see caracters not at the right places. Usually happens for about 1-2 seconds and a bit before my computer freezes. I have to keep the power button pressed for 4 seconds to shut my computer down. I still hear my hard drives and fans working. Sometimes it works with no problems for a full day, some other times it just keeps freezing each time I restart my computer and I have to leave it for the rest of the day. Sometimes my mouse freezes for a fraction of a second (Like 0.01 to 0.2 seconds) quite randomly, usually before it freezes. No errors spotted by the "Action center" unlike when I had problems with my last video card on this system (Driver errors). My G-15 LCD screen also freezes. What I did so far I have had similar problems in the past and I had changed my hard drive (It was faulty), so I tested my software RAID-0 array and it was faulty so I changed it. (I reinstalled Windows 7 with this part). I also tested with unplugging my secondary hard drive. My CPU was running at about 100 degree Celsius, I removed the dust between the fans and the heatsink and it's now between 50-60. I ran a CPU stress-test and it didn't freeze during the tests (using Prime95 on all cores) Ran a memory test (using memtest86+) for a single pass and there were no errors. Ran a GPU stress test with ati-tools and furmark and it didn't freeze during the tests. (No artefacts either) I had troubles with my graphic card when I got it, but I think that it got fixed with a driver update. I checked the voltages in my BIOS setup and they all seemed ok (±0.2 I think). I have ran on the computer without problems with Fedora 15 on an external hard drive (Appart that it couldn't load Gnome 3 and was reverting to Gnome 2, didn't want to install drivers since I use it on multiple computers) I used it to backup my files from the raid array to my 1TB hard drive for the reinstallation of Windows. (So the crashes only happenned on Windows) [The external hard drive is plugged directly on a SATA port] I contacted EVGA (My graphic card vendor) and pointed them on this question, I'm looking for an answer. Ran sensors on Fedora 15 and got this output: http://pastebin.com/0BHJnAvu When it happens When I play video games (Mostly) When I play flash games (Second most) When I'm looking at my desktop background (It rarely happens when I have a window open, but it does, sometimes) Specs Windows Seven x64 Home Premium Motherboard: M2N-SLI Deluxe CPU: AMD Phenom 9950 x2 @ 2.6GHz Memory: Kingston 4x2GB Dual Channel (Pretty basic memory sticks) Hard drives: Was 2x250GB (Western digital caviar) in raid-0 + 1TB (WD caviar black), I replaced the raid array with a 750GB (WD caviar black) [Yes I removed the array from the raid configurations] 750W Power supply No overcloking. Ever. There have been some power-downs like 4-5 weeks ago, but the problem didn't start immediately after. (I wasn't home, so my computer got shut-down) My current to-try list Change the thermal paste on my CPU. Change my graphic card with a temporary one and stress the computer. Change my power supply. In this situation, how can I successfully pin-point the current hardware problem? (If it's a hardware problem) Because I don't really have the budget to just forget and replace everything. I also don't really have hardware to test-replace current hardware.

  • How can I check if PHP was compiled with the UNICODE version of the Win32 API?

    - by Wesley Murch
    This is related to this Stack Overflow post: glob() can't find file names with multibyte characters on Windows? I'm having issues with PHP and files that have multibyte characters on Windows. Here's my test case: print_r(scandir('./uploads/')); print_r(glob('./uploads/*')); Correct Output on remote UNIX server: Array ( [0] => . [1] => .. [2] => filename-äöü.jpg [3] => filename.jpg [4] => test?test.jpg [5] => ??? ?????.jpg [6] => ?????????.jpg [7] => ???.jpg ) Array ( [0] => ./uploads/filename-äöü.jpg [1] => ./uploads/filename.jpg [2] => ./uploads/test?test.jpg [3] => ./uploads/??? ?????.jpg [4] => ./uploads/?????????.jpg [5] => ./uploads/???.jpg ) Incorrect Output locally on Windows: Array ( [0] => . [1] => .. [2] => ??? ?????.jpg [3] => ???.jpg [4] => ?????????.jpg [5] => filename-äöü.jpg [6] => filename.jpg [7] => test?test.jpg ) Array ( [0] => ./uploads/filename-äöü.jpg [1] => ./uploads/filename.jpg ) Here's a relevant excerpt from the answer I chose to accept (which actually is a quote from an article that was posted online over 2 years ago): From the comments on this article: http://www.rooftopsolutions.nl/blog/filesystem-encoding-and-php The output from your PHP installation on Windows is easy to explain : you installed the wrong version of PHP, and used a version not compiled to use the Unicode version of the Win32 API. For this reason, the filesystem calls used by PHP will use the legacy "ANSI" API and so the C/C++ libraries linked with this version of PHP will first try to convert yout UTF-8-encoded PHP string into the local "ANSI" codepage selected in the running environment (see the CHCP command before starting PHP from a command line window) Your version of Windows is MOST PROBABLY NOT responsible of this weird thing. Actually, this is YOUR version of PHP which is not compiled correctly, and that uses the legacy ANSI version of the Win32 API (for compatibility with the legacy 16-bit versions of Windows 95/98 whose filesystem support in the kernel actually had no direct support for Unicode, but used an internal conversion layer to convert Unicode to the local ANSI codepage before using the actual ANSI version of the API). Recompile PHP using the compiler option to use the UNICODE version of the Win32 API (which should be the default today, and anyway always the default for PHP installed on a server that will NEVER be Windows 95 or Windows 98...) I can't confirm whether this is my problem or not. I used phpinfo() and did not find anything interesting, but I wasn't sure what to look for. I've been using XAMPP for easy installations, so I'm really not sure exactly how it was installed. I'm using Windows 7, 64 bit - so forgive my ignorance, but I'm not even sure if "Win32" is relevant here. How can I check if my current version of PHP was compiled with the configuration mentioned above? PHP Version: 5.3.8 System: Windows NT WES-PC 6.1 build 7601 (Windows 7 Home Premium Edition Service Pack 1) i586 Build Date: Aug 23 2011 11:47:20 Compiler: MSVC9 (Visual C++ 2008) Architecture: x86 Configure Command: cscript /nologo configure.js "--enable-snapshot-build" "--disable-isapi" "--enable-debug-pack" "--disable-isapi" "--without-mssql" "--without-pdo-mssql" "--without-pi3web" "--with-pdo-oci=D:\php-sdk\oracle\instantclient10\sdk,shared" "--with-oci8=D:\php-sdk\oracle\instantclient10\sdk,shared" "--with-oci8-11g=D:\php-sdk\oracle\instantclient11\sdk,shared" "--enable-object-out-dir=../obj/" "--enable-com-dotnet" "--with-mcrypt=static" "--disable-static-analyze"

  • Setting environment variables in OS X

    - by Percival Ulysses
    Despite the warning that questions that can be answered are preferred, this question is more a request for comments. I apologize for this, but I feel that it is valuable nonetheless. The problem to set up environment variables such that they are available for GUI applications has been around since the dawn of Mac OS X. The solution with ~/.MacOSX/environment.plist never satisfied me because it was not reliable, and bash style globbing wasn't available. Another solution is the use of Login Hooks with a suitable shell script, but these are deprecated. The Apple approved way for such functionality as provided by login hooks is the use of Launch Agents. I provided a launch agent that is located in /Library/LaunchAgents/: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>user.conf.launchd</string> <key>Program</key> <string>/Users/Shared/conflaunchd.sh</string> <key>ProgramArguments</key> <array> <string>~/.conf.launchd</string> </array> <key>EnableGlobbing</key> <true/> <key>RunAtLoad</key> <true/> <key>LimitLoadToSessionType</key> <array> <string>Aqua</string> <string>StandardIO</string> </array> </dict> </plist> The real work is done in the shell script /Users/Shared/conflaunchd.sh, which reads ~/.conf.launchd and feeds it to launchctl: #! /bin/bash #filename="$1" filename="$HOME/.conf.launchd" if [ ! -r "$filename" ]; then exit fi eval $(/usr/libexec/path_helper -s) while read line; do # skip lines that only contain whitespace or a comment if [ ! -n "$line" -o `expr "$line" : '#'` -gt 0 ]; then continue; fi eval launchctl $line done <"$filename" exit 0 Notice the call of path_helper to get PATH set up right. Finally, ~/.conf.launchd looks like that setenv PATH ~/Applications:"${PATH}" setenv TEXINPUTS .:~/Documents/texmf//: setenv BIBINPUTS .:~/Documents/texmf/bibtex//: setenv BSTINPUTS .:~/Documents/texmf/bibtex//: # Locale setenv LANG en_US.UTF-8 These are launchctl commands, see its manpage for further information. Works fine for me (I should mention that I'm still a Snow Leopard guy), GUI applications such as texstudio can see my local texmf tree. Things that can be improved: The shell script has a #filename="$1" in it. This is not accidental, as the file name should be feeded to the script by the launch agent as an argument, but that doesn't work. It is possible to put the script in the launch agent itsself. I am not sure how secure this solution is, as it uses eval with user provided strings. It should be mentioned that Apple intended a somewhat similar approach by putting stuff in ~/launchd.conf, but it is currently unsupported as to this date and OS (see the manpage of launchd.conf). I guess that things like globbing would not work as they do in this proposal. Finally, I would mention the sources I used as information on Launch Agents, but StackExchange doesn't let me [1], [2], [3]. Again, I am sorry that this is not a real question, I still hope it is useful.

  • Scripting Windows Shares - VBS

    - by Calvin Piche
    So i am totally new to VBS, never used it. I am trying to create multiple shares and i found a Microsoft VBS script that can do this(http://gallery.technet.microsoft.com/scriptcenter/6309d93b-fcc3-4586-b102-a71415244712) My question is, this script only allows for one domain group or user to be added for permissions where i am needing to add a couple with different permissions(got that figured out) Below is the script that i have modified for my needs but just need to add in the second group with the other permissions.

  • Moving the swapfiles to a dedicated partition in Snow Leopard

    - by e.James
    I have been able to move Apple's virtual memory swapfiles to a dedicated partition on my hard drive up until now. The technique I have been using is described in a thread on forums.macosxhints.com. However, with the developer preview of Snow Leopard, this method no longer works. Does anyone know how it could be done with the new OS? Update: I have marked dblu's answer as accepted even though it didn't quite work because he gave excellent, detailed instructions and because his suggestion to use plutil ultimately pointed me in the right direction. The complete, working solution is posted here in the question because I don't have enough reputation to edit the accepted answer. Complete solution: 1. Open Terminal and make a backup copy of Apple's default dynamic_pager.plist: $ cd /System/Library/LaunchDaemons $ sudo cp com.apple.dynamic_pager.plist{,_bak} 2. Convert the plist from binary to plain XML: $ sudo plutil -convert xml1 com.apple.dynamic_pager.plist 3. Open the converted plist with your text editor of choice. (I use pico, see dblu's answer for an example using vim): $ sudo pico -w com.apple.dynamic_pager.plist It should look as follows: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs$ <plist version="1.0"> <dict> <key>EnableTransactions</key> <true/> <key>HopefullyExitsLast</key> <true/> <key>Label</key> <string>com.apple.dynamic_pager</string> <key>OnDemand</key> <false/> <key>ProgramArguments</key> <array> <string>/sbin/dynamic_pager</string> <string>-F</string> <string>/private/var/vm/swapfile</string> </array> </dict> </plist> 4. Change the ProgramArguments array (lines 13 through 18) so that it launches an intermediate shell script instead of launching dynamic_pager directly. See note #1 for details on why this is necessary. <key>ProgramArguments</key> <array> <string>/sbin/dynamic_pager_init</string> </array> 5. Save the plist, and return to the terminal prompt. Using pico, the commands would be: <ctrl+o> to save the file <enter> to accept the same filename (com.apple.dynamic_pager.plist) <ctrl+x> to exit 6. Convert the modified plist back to binary: $ sudo plutil -convert binary1 com.apple.dynamic_pager.plist 7. Create the intermediate shell script: $ cd /sbin $ sudo pico -w dynamic_pager_init The script should look as follows (my partition is called 'Swap', and I chose to put the swapfiles in a hidden directory on that partition, called '.vm' be sure that the directory you specify actually exists): Update: This version of the script makes use of wait4path as suggested by ZILjr: #!/bin/bash #launch Apple's dynamic_pager only when the swap volume is mounted echo "Waiting for Swap volume to mount"; wait4path /Volumes/Swap; echo "Launching dynamic pager on volume Swap"; /sbin/dynamic_pager -F /Volumes/Swap/.vm/swapfile; 8. Save and close dynamic_pager_init (same commands as step 5) 9. Modify permissions and ownership for dynamic_pager_init: $ sudo chmod a+x-w /sbin/dynamic_pager_init $ sudo chown root:wheel /sbin/dynamic_pager_init 10. Verify the permissions on dynamic_pager_init: $ ls -l dynamic_pager_init -r-xr-xr-x 1 root wheel 6 18 Sep 15:11 dynamic_pager_init 11. Restart your Mac. If you run into trouble, switch to verbose startup mode by holding down Command-v immediately after the startup chime. This will let you see all of the startup messages that appear during startup. If you run into even worse trouble (i.e. you never see the login screen), hold down Command-s instead. This will boot the computer in single-user mode (no graphical UI, just a command prompt) and allow you to restore the backup copy of com.apple.dynamic_pager.plist that you made in step 1. 12. Once the computer boots, fire up Terminal and verify that the swap files have actually been moved: $ cd /Volumes/Swap/.vm $ ls -l You should see something like this: -rw------- 1 someUser staff 67108864 18 Sep 12:02 swapfile0 13. Delete the old swapfiles: $ cd /private/var/vm $ sudo rm swapfile* 14. Profit! Note 1 Simply modifying the arguments to dynamic_pager in the plist does not always work, and when it fails, it does so in a spectacularly silent way. The problem stems from the fact that dynamic_pager is launched very early in the startup process. If your swap partition has not yet been mounted when dynamic_pager is first loaded (in my experience, this happens 99% of the time), then the system will fake its way through. It will create a symbolic link in your /Volumes directory which has the same name as your swap partition, but points back to the default swapfile location (/private/var/vm). Then, when your actual swap partition mounts, it will be given the name Swap 1 (or YourDriveName 1). You can see the problem by opening up Terminal and listing the contents of your /Volumes directory: $ cd /Volumes $ ls -l You will see something like this: drwxrwxrwx 11 yourUser staff 442 16 Sep 12:13 Swap -> private/var/vm drwxrwxrwx 14 yourUser staff 5 16 Sep 12:13 Swap 1 lrwxr-xr-x 1 root admin 1 17 Sep 12:01 System -> / Note that this failure can be very hard to spot. If you were to check for the swapfiles as I show in step 12, you would still see them! The symbolic link would make it seem as though your swapfiles had been moved, even though they were actually being stored in the default location. Note 2 I was originally unable to get this to work in Snow Leopard because com.apple.dynamic_pager.plist was stored in binary format. I made a copy of the original file and opened it with Apple's Property List Editor (available with Xcode) in order to make changes, but this process added some extended attributes to the plist file which caused the system to ignore it and just use the defaults. As dblu pointed out, using plutil to convert the file to plain XML works like a charm. Note 3 You can check the Console application to see any messages that dynamic_pager_init echos to the screen. If you see the following lines repeated over and over again, there is a problem with the setup. I ran into these messages because I forgot to create the '.vm' directory that I specified in dynamic_pager_init. com.apple.launchd[1] (com.apple.dynamic_pager[176]) Exited with exit code: 1 com.apple.launchd[1] (com.apple.dynamic_pager) Throttling respawn: Will start in 10 seconds When everything is working properly, you may see the above message a couple of times, but you should also see the following message, and then no more of the "Throttling respawn" messages afterwards. com.apple.dynamic_pager[???] Launching dynamic pager on volume Swap This means that the script did have to wait for the partition to load, but in the end it was successful.

  • How To Skip Commercials in Windows 7 Media Center

    - by DigitalGeekery
    If you use Windows 7 Media Center to record live TV, you’re probably interested in skipping through commercials. After all, a big reason to record programs is to avoid commercials, right? Today we focus on a fairly simple and free way to get you skipping commercials in no time. In Windows 7, the .wtv file format has replaced the dvr-ms file format used in previous versions of Media Center for Recorded TV. The .wtv file format, however, does not work very well with commercial skipping applications.  The Process Our first step will be to convert the recorded .wtv files to the previously used dvr-ms file format. This conversion will be done automatically by WtvWatcher. It’s important to note that this process deletes the original .wtv file after successfully converting to .dvr-ms. Next, we will use DVRMSToolBox with the DTB Addin to handle commercials skipping. This process does not “cut” or remove the commercials from the file. It merely skips the commercials during playback. WtvWatcher Download and install the WTVWatcher (link below). To install WtvWatcher, you’ll need to have Windows Installer 3.1 and .NET Framework 3.5 SP1. If you get the Publisher cannot be verified warning you can go ahead and click Install. We’ve completely tested this app and it contains no malware and runs successfully.   After installing, the WtvWatcher will pop up in the lower right corner of your screen. You will need to set the path to your Recorded TV directory. Click on the button for “Click here to set your recorded TV path…”   The WtvWatcher Preferences window will open…   …and you’ll be prompted to browse for your Recorded TV folder. If you did not change the default location at setup, it will be found at C:\Users\Public\Recorded TV. Click “OK” when finished. Click the “X” to close the Preferences screen. You should now see WtvWatcher begin to convert any existing WTV files.   The process should only take a few minutes per file. Note: If WtvWatcher detects an error during the conversion process, it will not delete the original WTV file.    You will probably want to run WtvWatcher on startup. This will allow WtvWatcher too constantly scan for new .wtv files to convert. There is no setting in the application to run on startup, so you’ll need to copy the WTV icon from your desktop into your Windows start menu “Startup” directory. To do so, click on Start > All Programs, right-click on Startup and click on Open all users. Drag and drop, or cut and paste, the WtvWatcher desktop shortcut into the Startup folder. DVRMSToolBox and DTBAddIn Next, we need to download and install the DVRMSToolBox and the DTBAddIn. These two pieces of software will do the actual commercial skipping. After downloading the DVRMSToolBox zip file, extract it and double-click the setup.exe file.  Click “Next” to begin the installation.   Unless DVRMSToolBox will only be used by Administrator accounts, check the “Modify File Permissions” box. Click “Next.” When you get to the Optional Components window, uncheck Download/Install ShowAnalyzer. We will not be using that application. When the installation is complete, click “Close.”    Next we need to install the DTBAddin. Unzip the download folder and run the appropriate .msi file for your system. It is available in 32 & 64 bit versions. Just double click on the file and take the default options. Click “Finish” when the install is completed. You will then be prompted to restart your computer. After your computer has restarted, open DVRMSToolBox settings by going to Start > All Programs, DVRMSToolBox, and click on DVRMStoMPEGSettings. On the MC Addin tab, make sure that Skip Commercials is checked. It should be by default.   On the Commercial Skip tab, make sure the Auto Skip option is selected. Click “Save.”   If you try to watch recorded TV before the file conversion and commercial indexing process is complete you’ll get the following message pop up in Media Center. If you click Yes, it will start indexing the commercials if WtvWatcher has already converted it to dvr-ms. Now you’re ready to kick back and watch your recorded tv without having to wait through those long commercial breaks. Conclusion The DVRMSToolBox is a powerful and complex application with a multitude of features and utilities. We’ve showed you a quick and easy way to get your Windows Media Center setup to skip commercials. This setup, like virtually all commercial skipping setups, is not perfect. You will occasionally find a commercial that doesn’t get skipped. Need help getting your Windows 7 PC configured for TV? Check out our previous tutorial on setting up live TV in Windows Media Center.

    I can't seem to figure out how to wrap the title of the widget in an tag. For example, I am trying to get it so that when you type the url in a text field, it is then placed in the tag so that it is a hyperlink on the website... class Example_Widget extends WP_Widget { /** * Widget setup. */ function Example_Widget() { /* Widget settings. */ $widget_ops = array( 'classname' => 'example', 'description' => __('A widget that displays company announcements.', 'example') ); /* Widget control settings. */ $control_ops = array( 'width' => 300, 'height' => 350, 'id_base' => 'example-widget' ); /* Create the widget. */ $this->WP_Widget( 'example-widget', __('Announcement Widget', 'example'), $widget_ops, $control_ops ); } /** * How to display the widget on the screen. */ function widget( $args, $instance ) { extract( $args ); /* Our variables from the widget settings. */ $title = apply_filters('widget_title', $instance['title'] ); $excerpt = $instance['excerpt']; $url = $instance['url']; /* Before widget (defined by themes). */ echo $before_widget; /* Display the widget title if one was input (before and after defined by themes). */ if ( $title ) echo $before_title . $title . $after_title; /* Display name from widget settings if one was input. */ if ( $excerpt ) printf( '<p style="font-family: arial; font-size: 12px; line-height: 16px;">' . __('%1$s.', 'example') .

  • Flex actionscript extending DateChooser, events in calendar

    - by Nemi
    ExtendedDateChooser class is great solution for simple event calendar used in my flex project. You can find it if google for "Adding-Calendar-Event-Entries-to-the-Flex-DateChooser-Component" with a link of updated solution in comments of the post. I posted files below. Problem in that calendar is text events are missing when month is changed. Is there updateCompleted event in Actionscript just like in dateChooser flex component? Like in: <mx:DateChooser id="dc" updateCompleted="goThroughDateChooserCalendarLayoutAndSetEventsInCalendarAgain()"</mx> When scroll event is added, which is available in Actionscript, it gets dispatched but after updateDisplayList() is fired, so didn't manage to answer, why are calendar events erased?

  • Microsoft TechEd 2010 - Day 3 @ Bangalore

    - by sathya
    Microsoft TechEd 2010 - Day 3 @ Bangalore Sorry for my delayed post on day 3 because I had to travel from Blore to Chennai So I couldnt write for the past two days. On day 3 as usual we had lot of simultaneous tracks on various sessions. This day I choose the Your Data, Our Platform Track. It had sessions on the following 5 topics :   Developing Data-tier Applications in Visual Studio 2010 - by Sanjay Nagamangalam SQL Server Query Optimization, Execution and Debugging Query Performance - by Vinod Kumar M SQL Server Utility - Its about more than 1 SQL Server - by Vinod Kumar Jagannathan Data Recovery / Consistency with CheckDB - by Vinod Kumar M Developing with SQL Server Spatial and Deep dive into Spatial Indexing - by Pinal Dave Developing Data-tier Applications in Visual Studio 2010 - by Sanjay Nagamangalam This was one of the superb sessions i have attended. He explained all the concepts in detail with a demo. The important thing in this is there is something called Data-Tier application project which is newly introduced in this VS2010 with which we can manage all our data along with our application inside our VS itself. We can create DB,Tables,Procs,Views etc. here itself and once we deploy it creates a compressed file called .dacpac which stores all the changes in Table Schema,Created procs, etc. on to that single file which reduces our (developer's) effort in preparing the deployment scripts and giving it to the DBA. It also has some policy configurations which can be managed easily by checking some rules like in outlook. For Ex : IF the SQL Server Version > 10 then deploy else dont. This rule specifies that even if we try to deploy on SQL Server DB with version less than 10 It will not do it. And if we deploy some .dacpac to SQL server production db with the option upgrade DB with this dacpac once everything completes successfully it will say success else it rollsback to the prior version. Even if it gets deployed successfully and later @ a point of time you wish to revert it back to the prior version, you can go ahead and delete the existing dacpac version so that it reverts to the older version of the db changes. And for the good questions that were asked in the session T-Shirts were given. SQL Server Query Optimization, Execution and Debugging Query Performance - by Vinod Kumar M This one too was the best session. The speaker Vinod explained everything very much clearly. This was really useful session and you dont believe, as per my knowledge, in the total 3 days in the TechEd except the Keynote, for this session seats were full (House FULL)  People were even standing out to attend this session. Such a great one it was. The speaker did a deep dive in to the Query Plan section and showed which actually causes the problem. Its all about the thing that we need to understand about the execution of SQL server Queries. We think in a way and SQL Server never executes in that way. We need to understand that first. He also told about there might be two plans generated for a single query at a point of time because of parallel processors in the system. The Key is here in every query. There is something called Estimated Row Count and Actual Row Count in the query plan. If the estimated row count by SQL server tallies with the actual row count your performance will be awesome. He said some tweaks to achieve the same. After this as usual we had lunch SQL Server Utility - Its about more than 1 SQL Server - by Vinod Kumar Jagannathan This was more of a DBA's session. Am really sorry I was totally blank and I was not interested to attend this session and walked out to attend Migrating to the cloud by Harish Ranganathan (My favorite Speaker) but unfortunately that was some other persons session. There the speaker was telling about how to configure the connection strings in such a way that we can connect to the SQL Azure platform from our VS and also showed us how to deploy the same in to Windows Azure. In between there were lot of technical problems like laptop hang, user locked and he was switching between systems, also i came in the half so i wasnt able to listen that fully. In between, Since I got an MCTS certification they gave me T-Shirt with the lines 'Iam Certified. Are you?' and they asked me to wear that. If we wear that we might get spotted and they would give us some goodies  So on the 3rd day I was wearing that T-Shirt. I got spotted by the person Tarun who was coordinating things about the certification, and he was accompanied with a cameraman and they interviewed me about the certification and I was shown live in the Teched and was seen by 60000 live viewers of the TechEd. I was really happy on that. Data Recovery / Consistency with CheckDB - by Vinod Kumar M This was one of the best sessions too in the TechEd. This guy is really amazing. In front of us he crashed a DB and showed how to recover the same in 6 different ways for different no of failures.

He had a lot of obstacles during his session like rain coming inside the hall, mic wires got bursted due to rain, Videos off on the display screens. In spite of that he asked the audience to come in the front rows and managed to take a good session without ppts and finally we got the displays on and he was showing demos on the same what he explained orally. That was really a fun filled informative session. He gave some books for the persons who asked good questions and answered well for his questions and I got one too  (It was a book on Data Mining - Wrox Publishers) And finally after all these things there was Keynote session for close of the TechEd. and we all assembled in a big hall where Mr.Ashok Soota, a man of age around 70  co-founder of Mindtree was called to give some lecture on his successes. He was explaining about his past and what all companies he switched and for what reasons and what are all his successes and what are all his failures and the learnings of him from his past failures. and his success and failures on his partnerships with the other concern. And there were some questions for him like What is your suggestion on young entrepreneur? How did you learn from past failures? What is reiterating your success? What is your suggestion on partnerships? How to choose partnerships? etc. And they said @ 7.30 Pm there would be a party night, but unfortunately i was not able to attend that because I had to catch my train and before that i had to pack things, so I started @ 7 itself. Thats it about the TechED!!! Stay tuned for further Technology updates.

  • Prime Numbers Code Help

    - by andrew
    Hello Everybody, I am suppose to "write a Java program that reads a positive integer n from standard input, then prints out the first n prime number." It's divided into 3 parts. 1st: This function will return true or false according to whether m is prime or composite. The array argument P will contain a sufficient number of primes to do the testing. Specifically, at the time isPrime() is called, array P must contain (at least) all primes p in the range 2 p m . For instance, to test m = 53 for primality, one must do successive trial divisions by 2, 3, 5, and 7. We go no further since 11 53 . Thus a precondition for the function call isPrime(53, P) is that P[0] = 2 , P[1] = 3 , P[2] = 5, and P[3] = 7 . The return value in this case would be true since all these divisions fail. Similarly to test m =143 , one must do trial divisions by 2, 3, 5, 7, and 11 (since 13 143 ). The precondition for the function call isPrime(143, P) is therefore P[0] = 2 , P[1] = 3 , P[2] = 5, P[3] = 7 , and P[4] =11. The return value in this case would be false since 11 divides 143. Function isPrime() should contain a loop that steps through array P, doing trial divisions. This loop should terminate when 2 either a trial division succeeds, in which case false is returned, or until the next prime in P is greater than m , in which case true is returned. Then there is the "main function" • Check that the user supplied exactly one command line argument which can be interpreted as a positive integer n. If the command line argument is not a single positive integer, your program will print a usage message as specified in the examples below, then exit. • Allocate array Primes[] of length n and initialize Primes[0] = 2 . • Enter a loop which will discover subsequent primes and store them as Primes[1] , Primes[2], Primes[3] , ……, Primes[n -1] . This loop should contain an inner loop which walks through successive integers and tests them for primality by calling function isPrime() with appropriate arguments. • Print the contents of array Primes[] to stdout, 10 to a line separated by single spaces. In other words Primes[0] through Primes[9] will go on line 1, Primes[10] though Primes[19] will go on line 2, and so on. Note that if n is not a multiple of 10, then the last line of output will contain fewer than 10 primes. The last function is called "usage" which I am not sure how to execute this! Your program will include a function called Usage() having signature static void Usage() that prints this message to stderr, then exits. Thus your program will contain three functions in all: main(), isPrime(), and Usage(). Each should be preceded by a comment block giving it’s name, a short description of it’s operation, and any necessary preconditions (such as those for isPrime().) And hear is my code, but I am having a bit of a problem and could you guys help me fix it? If I enter the number "5" it gives me the prime numbers which are "6,7,8,9" which doesn't make much sense. import java.util.; import java.io.; import java.lang.*; public class PrimeNumber { static boolean isPrime(int m, int[] P){ int squarert = Math.round( (float)Math.sqrt(m) ); int i = 2; boolean ans=false; while ((i<=squarert) & (ans==false)) { int c= P[i]; if (m%c==0) ans= true; else ans= false; i++; } /* if(ans ==true) ans=false; else ans=true; return ans; } ///****main public static void main(String[] args ) { Scanner in= new Scanner(System.in); int input= in.nextInt(); int i, j; int squarert; boolean ans = false; int userNum; int remander = 0; System.out.println("input: " + input); int[] prime = new int[input]; prime[0]= 2; for(i=1; i ans = isPrime(j,prime); j++;} prime[i] = j; } //prnt prime System.out.println("The first " + input + " prime number(s) are: "); for(int r=0; r }//end of main } Thanks for the help

  • Using the BAM Interceptor with Continuation

    - by Charles Young
    Originally posted on: http://geekswithblogs.net/cyoung/archive/2014/06/02/using-the-bam-interceptor-with-continuation.aspxI’ve recently been resurrecting some code written several years ago that makes extensive use of the BAM Interceptor provided as part of BizTalk Server’s BAM event observation library.  In doing this, I noticed an issue with continuations.  Essentially, whenever I tried to configure one or more continuations for an activity, the BAM Interceptor failed to complete the activity correctly.   Careful inspection of my code confirmed that I was initializing and invoking the BAM interceptor correctly, so I was mystified.  However, I eventually found the problem.  It is a logical error in the BAM Interceptor code itself. The BAM Interceptor provides a useful mechanism for implementing dynamic tracking.  It supports configurable ‘track points’.  These are grouped into named ‘locations’.  BAM uses the term ‘step’ as a synonym for ‘location’.   Each track point defines a BAM action such as starting an activity, extracting a data item, enabling a continuation, etc.  Each step defines a collection of track points. Understanding Steps The BAM Interceptor provides an abstract model for handling configuration of steps.  It doesn’t, however, define any specific configuration mechanism (e.g., config files, SSO, etc.)  It is up to the developer to decide how to store, manage and retrieve configuration data.  At run time, this configuration is used to register track points which then drive the BAM Interceptor. The full semantics of a step are not immediately clear from Microsoft’s documentation.  They represent a point in a business activity where BAM tracking occurs.  They are named locations in the code.  What is less obvious is that they always represent either the full tracking work for a given activity or a discrete fragment of that work which commences with the start of a new activity or the continuation of an existing activity.  The BAM Interceptor enforces this by throwing an error if no ‘start new’ or ‘continue’ track point is registered for a named location. This constraint implies that each step must marked with an ‘end activity’ track point.  One of the peculiarities of BAM semantics is that when an activity is continued under a correlated ID, you must first mark the current activity as ‘ended’ in order to ensure the right housekeeping is done in the database.  If you re-start an ended activity under the same ID, you will leave the BAM import tables in an inconsistent state.  A step, therefore, always represents an entire unit of work for a given activity or continuation ID.  For activities with continuation, each unit of work is termed a ‘fragment’. Instance and Fragment State Internally, the BAM Interceptor maintains state data at two levels.  First, it represents the overall state of the activity using a ‘trace instance’ token.  This token contains the name and ID of the activity together with a couple of state flags.  The second level of state represents a ‘trace fragment’.   As we have seen, a fragment of an activity corresponds directly to the notion of a ‘step’.  It is the unit of work done at a named location, and it must be bounded by start and end, or continue and end, actions. When handling continuations, the BAM Interceptor differentiates between ‘root’ fragments and other fragments.  Very simply, a root fragment represents the start of an activity.  Other fragments represent continuations.  This is where the logic breaks down.  The BAM Interceptor loses state integrity for root fragments when continuations are defined. Initialization Microsoft’s BAM Interceptor code supports the initialization of BAM Interceptors from track point configuration data.  The process starts by populating an Activity Interceptor Configuration object with an array of track points.  These can belong to different steps (aka ‘locations’) and can be registered in any order.  Once it is populated with track points, the Activity Interceptor Configuration is used to initialise the BAM Interceptor.  The BAM Interceptor sets up a hash table of array lists.  Each step is represented by an array list, and each array list contains an ordered set of track points.  The BAM Interceptor represents track points as ‘executable’ components.  When the OnStep method of the BAM Interceptor is called for a given step, the corresponding list of track points is retrieved and each track point is executed in turn.  Each track point retrieves any required data using a call back mechanism and then serializes a BAM trace fragment object representing a specific action (e.g., start, update, enable continuation, stop, etc.).  The serialised trace fragment is then handed off to a BAM event stream (buffered or direct) which takes the appropriate action. The Root of the Problem The logic breaks down in the Activity Interceptor Configuration.  Each Activity Interceptor Configuration is initialised with an instance of a ‘trace instance’ token.  This provides the basic metadata for the activity as a whole.  It contains the activity name and ID together with state flags indicating if the activity ID is a root (i.e., not a continuation fragment) and if it is completed.  This single token is then shared by all trace actions for all steps registered with the Activity Interceptor Configuration. Each trace instance token is automatically initialised to represent a root fragment.  However, if you subsequently register a ‘continuation’ step with the Activity Interceptor Configuration, the ‘root’ flag is set to false at the point the ‘continue’ track point is registered for that step.   If you use a ‘reflector’ tool to inspect the code for the ActivityInterceptorConfiguration class, you can see the flag being set in one of the overloads of the RegisterContinue method.    This makes no sense.  The trace instance token is shared across all the track points registered with the Activity Interceptor Configuration.  The Activity Interceptor Configuration is designed to hold track points for multiple steps.  The ‘root’ flag is clearly meant to be initialised to ‘true’ for the preliminary root fragment and then subsequently set to false at the point that a continuation step is processed.  Instead, if the Activity Interceptor Configuration contains a continuation step, it is changed to ‘false’ before the root fragment is processed.  This is clearly an error in logic. The problem causes havoc when the BAM Interceptor is used with continuation.  Effectively the root step is no longer processed correctly, and the ultimate effect is that the continued activity never completes!   This has nothing to do with the root and the continuation being in the same process.  It is due to a fundamental mistake of setting the ‘root’ flag to false for a continuation before the root fragment is processed. The Workaround Fortunately, it is easy to work around the bug.  The trick is to ensure that you create a new Activity Interceptor Configuration object for each individual step.  This may mean filtering your configuration data to extract the track points for a single step or grouping the configured track points into individual steps and the creating a separate Activity Interceptor Configuration for each group.  In my case, the first approach was required.  Here is what the amended code looks like: // Because of a logic error in Microsoft's code, a separate ActivityInterceptorConfiguration must be used // for each location. The following code extracts only those track points for a given step name (location). var trackPointGroup = from ResolutionService.TrackPoint tp in bamActivity.TrackPoints                       where (string)tp.Location == bamStepName                       select tp; var bamActivityInterceptorConfig =     new Microsoft.BizTalk.Bam.EventObservation.ActivityInterceptorConfiguration(activityName); foreach (var trackPoint in trackPointGroup) {     switch (trackPoint.Type)     {         case TrackPointType.Start:             bamActivityInterceptorConfig.RegisterStartNew(trackPoint.Location, trackPoint.ExtractionInfo);             break; etc… I’m using LINQ to filter a list of track points for those entries that correspond to a given step and then registering only those track points on a new instance of the ActivityInterceptorConfiguration class.   As soon as I re-wrote the code to do this, activities with continuations started to complete correctly.

  • Should I refactor this code?

    - by user156814
    The code is for a view debate page. The code is supposed to determine whether or not to show an add reply form to the viewing user. If the user is logged in, and the user is not the creator of the debate, then check if the user already replied to the debate. If the user did not already reply to the debate then show the form... Otherwise, Check If the user wants to edit their already existing reply by looking in the url for the reply id If any of these tests dont pass, Then I save the reason as an int and pass that to a switch statement in the view. The logic seems easy enough, but my code seems a little sloppy. Here's the code.. (using Kohana V2.3.4) public function view($id = 0) { $debate = ORM::factory('debate')->with('user')->with('category')->find($id); if ($debate->loaded == FALSE) { url::redirect(); } // series of tests to show an add reply form if ($this->logged_in) { // is the viewer the creator? if ($this->user->id != $debate->user->id) { // has the user already replied? if (ORM::factory('reply') ->where(array('debate_id' => $id, 'user_id' => $this->user->id)) ->count_all() == 0) { $form = $errors = array ( 'body' => '', 'choice_id' => '', 'add' => '' ); if ($post = $this->input->post()) { $reply = ORM::factory('reply'); // validate and insert the reply if ($reply->add($post, TRUE)) { url::redirect(url::current()); } $form = arr::overwrite($form, $post->as_array()); $errors = arr::overwrite($errors, $post->errors('reply_errors')); } } // editing a reply? else if (($rid = (int) $this->input->get('edit')) AND ($reply = ORM::factory('reply') ->where(array('debate_id' => $id, 'user_id' => $this->user->id)) ->find($rid))) { $form = $errors = array ( 'body' => '', 'choice_id' => '', 'add' => '' ); // autocomplete the form $form = arr::overwrite($form, $reply->as_array()); if ($post = $this->input->post()) { // validate and insert the reply if ($reply->edit($post, TRUE)) { url::redirect(url::current()); } $form = arr::overwrite($form, $post->as_array()); $errors = arr::overwrite($errors, $post->errors('reply_errors')); } } else { // user already replied $reason = 3; } } else { // user started the debate $reason = 2; } } else { // user is not logged in. $reason = 1; } $limits = Kohana::config('app/debate.limits'); $page = (int) $this->input->get('page', 1); $offset = ($page > 0) ? ($page - 1) * $limits['replies'] : 0; $replies = ORM::factory('reply')->with('user')->with('choice')->where('replies.debate_id', $id); $this->template->title = $debate->topic; $this->template->debate = $debate; $this->template->body = View::factory('debate/view') ->set('debate', $debate) ->set('replies', $replies->find_all($limits['replies'], $offset)) ->set('pagination', Pagination::factory(array ( 'style' => 'digg', 'items_per_page' => $limits['replies'], 'query_string' => 'page', 'auto_hide' => TRUE, 'total_items' => $total = $replies->count_last_query() )) ) ->set('total', $total); // are we showing the add reply form? if (isset($form, $errors)) { $this->template->body->add_reply_form = View::factory('reply/add_reply_form') ->set('debate', $debate) ->set('form', $form) ->set('errors', $errors); } else { $this->template->body->reason = $reason; } } Heres the view, theres some logic in here that determines what message to show the user. <!-- Add Reply Form --> <?php if (isset($add_reply_form)): ?> <?php echo $add_reply_form; ?> <?php else: ?> <?php switch ($reason) { case 1 : // not logged in, show a message $message = 'Add your ' . html::anchor('login?url=' . url::current(TRUE), '<b>vote</b>') . ' to this discussion'; break; case 2 : // started the debate. dont show a message for that. $message = NULL; break; case 3: // already replied, show a message $message = 'You have already replied to this debate'; break; default: // unknown reason. dont show a message $message = NULL; break; } ?> <?php echo app::show_message($message, 'h2'); ?> <?php endif; ?> <!-- End Add Reply Form --> Should I refactor the add reply logic into another function or something.... It all works, it just seems real sloppy. Thanks

  • How to get my list of rows from database to show while using Zend-Paginator

    - by Matto
    I'm fairly new to the world of Zend-Framework, and have taken over a site that is in zend-framework. There is a bug on one of the pages right now and I can not figure it out. I think it has something to do with Zend Paginator, but not sure. This is the code in the controller for the section I am having a problem with: $currentPage = $this->_getParam('page'); $numWebsitesFullOnline = $websites->getWebsitesFullOnline(); $select = $websites->select(); $select->setIntegrityCheck(false); $select->from(array('w' => 'websites'), array('id', 'online', 'kw_adjective', 'kw_name', 'kw_location', 'url', 'email', 'address', 'ftp_server', 'ftp_username', 'ftp_password', 'ftp_folder', 'phone_number', 'indexed', 'youtube_position', 'twitter_user', 'facebook_id', 'video_made', 'image1_id', 'image2_id', 'image3_id', 'bg_color', 'dark_color', 'light_color', 'links_color', 'text_color', 'google_account', 'ganalytics', 'gmaps_status', 'google_position', 'gmap_position', 'hp1', 'hp2', 'hp3', 'hp4', 'hp5', 'hp6', 'hp7', 'hp8', 'hp9', 'hp10', 'about1_id', 'about2_id', 'about3_id', 'tip1_id', 'tip2_id', 'tip3_id', 'contact_texts_id', 'quote_texts_id', 'demographics_id')) ->join(array('d' => 'demographics'), 'w.demographics_id = d.id', array('total_population')) ->order(array('total_population DESC', 'kw_location')); $paginator = new Zend_Paginator(new Zend_Paginator_Adapter_DbSelect($select)); $paginator->setItemCountPerPage(50); $paginator->setCurrentPageNumber($currentPage); $paginator->setPageRange(($paginator->getTotalItemCount() / 50) + 1); $this->view->paginator = $paginator; $numWebsitesOnline = $websites->getWebsitesOnline(); On the php page I have this code to call the websites that are in the database to a list: <p class="red"> Websites online: <?php echo $this->numOnline; ?> </p> <?php print_r(count($this->paginator)); ?> <?php if(count($this->paginator)): ?> <table class="table-list"> <?php foreach($this->paginator as $item): ?> <tr> <?php if($this->userIsAllowedAction('websites', 'reload')): ?> <td class="center noborder w30"> <img class="hidden" src="<?php echo $this->baseUrl() .

So it sees that there is one row in the websites table of the database, but it is not returning anything to page and listing out the rows in the websites table. Not sure if this is the paginator that is causing this cause it is returning 0 or something else I don't know about.

  • Drupal Adding Span inside A tags in Nice Menus

    - by Chris
    I am trying to add drop down menus to a drupal theme which uses text sliding door CSS rounding. The current version uses a primary links injection of the span into the a tags, which works fine. But doesn't support drop down menus. Working code: <?php print theme('links', $primary_links, array('class' => 'links primary-links')) ?> In the template with a template.php file addition: <?php // function for injecting spans inside anchors which we need for the theme's rounded corner background images function strands_guybrush_links($links, $attributes = array('class' => 'links')) { $output = ''; if (count($links) > 0) { $output = '<ul'. drupal_attributes($attributes) .'>'; $num_links = count($links); $i = 1; foreach ($links as $key => $link) { $class = $key; // Add first, last and active classes to the list of links to help out themers. if ($i == 1) { $class .= ' first'; } if ($i == $num_links) { $class .= ' last'; } if (isset($link['href']) && ($link['href'] == $_GET['q'] || ($link['href'] == '<front>' && drupal_is_front_page()))) { $class .= ' active'; } $output .= '<li'. drupal_attributes(array('class' => $class)) .'>'; if (isset($link['href'])) { $link['title'] = '<span class="link">' . check_plain($link['title']) . '</span>'; $link['html'] = TRUE; // Pass in $link as $options, they share the same keys. $output .= l($link['title'], $link['href'], $link); } else if (!empty($link['title'])) { // Some links are actually not links, but we wrap these in <span> for adding title and class attributes if (empty($link['html'])) { $link['title'] = check_plain($link['title']); } $span_attributes = ''; if (isset($link['attributes'])) { $span_attributes = drupal_attributes($link['attributes']); } $output .= '<span'. $span_attributes .'>'. $link['title'] .'</span>'; } $i++; $output .= "</li>\n"; } $output .= '</ul>'; } return $output; } ?> So I have added the [Nice Menu module][1] which works well and allows the drop down menu functions for my navigation which is now addressed from the template using: <?php print theme_nice_menu_primary_links() ?> The issue is that the a tags need to have spans inside to allow for the selected state markup. I have tried every angle I could find to edit the drupal function menu_item_link which is used by nice menus to build the links. E.g. I looked at the drupal forum for two days and no joy. The lines in the module that build the links are: function theme_nice_menu_build($menu) { $output = ''; // Find the active trail and pull out the menus ids. menu_set_active_menu_name('primary-links'); $trail = menu_get_active_trail('primary-links'); foreach ($trail as $item) { $trail_ids[] = $item['mlid']; } foreach ($menu as $menu_item) { $mlid = $menu_item['link']['mlid']; // Check to see if it is a visible menu item. if ($menu_item['link']['hidden'] == 0) { // Build class name based on menu path // e.g. to give each menu item individual style. // Strip funny symbols. $clean_path = str_replace(array('http://', '<', '>', '&', '=', '?', ':'), '', $menu_item['link']['href']); // Convert slashes to dashes. $clean_path = str_replace('/', '-', $clean_path); $class = 'menu-path-'. $clean_path; $class .= in_array($mlid, $trail_ids) ? ' active' : ''; // If it has children build a nice little tree under it. if ((!empty($menu_item['link']['has_children'])) && (!empty($menu_item['below']))) { // Keep passing children into the function 'til we get them all. $children = theme('nice_menu_build', $menu_item['below']); // Set the class to parent only of children are displayed. $class .= $children ? ' menuparent ' : ''; // Add an expanded class for items in the menu trail. $output .= '<li id="menu-'. $mlid .'" class="'. $class .'">'. theme('menu_item_link', $menu_item['link']); // Build the child UL only if children are displayed for the user. if ($children) { $output .= '<ul>'; $output .= $children; $output .= "</ul>\n"; } $output .= "</li>\n"; } else { $output .= '<li id="menu-'. $mlid .'" class="'. $class .'">'. theme('menu_item_link', $menu_item['link']) .'</li>'."\n"; } } } return $output; } As you can see the $output uses menu_item_link to parse the array into links and to added the class of active to the selected navigation link. The question is how do I add a span inside the a tags OR how do I wrap the a tags with a span that has the active class to style the sliding door links? drupal.org/project/nice_menus drupal.org/node/53233

  • Columnstore Case Study #2: Columnstore faster than SSAS Cube at DevCon Security

    - by aspiringgeek
    Preamble This is the second in a series of posts documenting big wins encountered using columnstore indexes in SQL Server 2012 & 2014.  Many of these can be found in my big deck along with details such as internals, best practices, caveats, etc.  The purpose of sharing the case studies in this context is to provide an easy-to-consume quick-reference alternative. See also Columnstore Case Study #1: MSIT SONAR Aggregations Why Columnstore? As stated previously, If we’re looking for a subset of columns from one or a few rows, given the right indexes, SQL Server can do a superlative job of providing an answer. If we’re asking a question which by design needs to hit lots of rows—DW, reporting, aggregations, grouping, scans, etc., SQL Server has never had a good mechanism—until columnstore. Columnstore indexes were introduced in SQL Server 2012. However, they're still largely unknown. Some adoption blockers existed; yet columnstore was nonetheless a game changer for many apps.  In SQL Server 2014, potential blockers have been largely removed & they're going to profoundly change the way we interact with our data.  The purpose of this series is to share the performance benefits of columnstore & documenting columnstore is a compelling reason to upgrade to SQL Server 2014. The Customer DevCon Security provides home & business security services & has been in business for 135 years. I met DevCon personnel while speaking to the Utah County SQL User Group on 20 February 2012. (Thanks to TJ Belt (b|@tjaybelt) & Ben Miller (b|@DBADuck) for the invitation which serendipitously coincided with the height of ski season.) The App: DevCon Security Reporting: Optimized & Ad Hoc Queries DevCon users interrogate a SQL Server 2012 Analysis Services cube via SSRS. In addition, the SQL Server 2012 relational back end is the target of ad hoc queries; this DW back end is refreshed nightly during a brief maintenance window via conventional table partition switching. SSRS, SSAS, & MDX Conventional relational structures were unable to provide adequate performance for user interaction for the SSRS reports. An SSAS solution was implemented requiring personnel to ramp up technically, including learning enough MDX to satisfy requirements. Ad Hoc Queries Even though the fact table is relatively small—only 22 million rows & 33GB—the table was a typical DW table in terms of its width: 137 columns, any of which could be the target of ad hoc interrogation. As is common in DW reporting scenarios such as this, it is often nearly to optimize for such queries using conventional indexing. DevCon DBAs & developers attended PASS 2012 & were introduced to the marvels of columnstore in a session presented by Klaus Aschenbrenner (b|@Aschenbrenner) The Details Classic vs. columnstore before-&-after metrics are impressive. Scenario   Conventional Structures   Columnstore   Δ SSRS via SSAS 10 - 12 seconds 1 second >10x Ad Hoc 5-7 minutes (300 - 420 seconds) 1 - 2 seconds >100x Here are two charts characterizing this data graphically.  The first is a linear representation of Report Duration (in seconds) for Conventional Structures vs. Columnstore Indexes.  As is so often the case when we chart such significant deltas, the linear scale doesn’t expose some the dramatically improved values corresponding to the columnstore metrics.  Just to make it fair here’s the same data represented logarithmically; yet even here the values corresponding to 1 –2 seconds aren’t visible.  The Wins Performance: Even prior to columnstore implementation, at 10 - 12 seconds canned report performance against the SSAS cube was tolerable. Yet the 1 second performance afterward is clearly better. As significant as that is, imagine the user experience re: ad hoc interrogation. The difference between several minutes vs. one or two seconds is a game changer, literally changing the way users interact with their data—no mental context switching, no wondering when the results will appear, no preoccupation with the spinning mind-numbing hurry-up-&-wait indicators.  As we’ve commonly found elsewhere, columnstore indexes here provided performance improvements of one, two, or more orders of magnitude. Simplified Infrastructure: Because in this case a nonclustered columnstore index on a conventional DW table was faster than an Analysis Services cube, the entire SSAS infrastructure was rendered superfluous & was retired. PASS Rocks: Once again, the value of attending PASS is proven out. The trip to Charlotte combined with eager & enquiring minds let directly to this success story. Find out more about the next PASS Summit here, hosted this year in Seattle on November 4 - 7, 2014. DevCon BI Team Lead Nathan Allan provided this unsolicited feedback: “What we found was pretty awesome. It has been a game changer for us in terms of the flexibility we can offer people that would like to get to the data in different ways.” Summary For DW, reports, & other BI workloads, columnstore often provides significant performance enhancements relative to conventional indexing.  I have documented here, the second in a series of reports on columnstore implementations, results from DevCon Security, a live customer production app for which performance increased by factors of from 10x to 100x for all report queries, including canned queries as well as reducing time for results for ad hoc queries from 5 - 7 minutes to 1 - 2 seconds. As a result of columnstore performance, the customer retired their SSAS infrastructure. I invite you to consider leveraging columnstore in your own environment. Let me know if you have any questions.

  • Unlocking Productivity

    - by Michael Snow
    Unlocking Productivity in Life Sciences with Consolidated Content Management by Joe Golemba, Vice President, Product Management, Oracle WebCenter As life sciences organizations look to become more operationally efficient, the ability to effectively leverage information is a competitive advantage. Whether data mining at the drug discovery phase or prepping the sales team before a product launch, content management can play a key role in developing, organizing, and disseminating vital information. The goal of content management is relatively straightforward: put the information that people need where they can find it. A number of issues can complicate this; information sits in many different systems, each of those systems has its own security, and the information in those systems exists in many different formats. Identifying and extracting pertinent information from mountains of farflung data is no simple job, but the alternative—wasted effort or even regulatory compliance issues—is worse. An integrated information architecture can enable health sciences organizations to make better decisions, accelerate clinical operations, and be more competitive. Unstructured data matters Often when we think of drug development data, we think of structured data that fits neatly into one or more research databases. But structured data is often directly supported by unstructured data such as experimental protocols, reaction conditions, lot numbers, run times, analyses, and research notes. As life sciences companies seek integrated views of data, they are typically finding diverse islands of data that seemingly have no relationship to other data in the organization. Information like sales reports or call center reports can be locked into siloed systems, and unavailable to the discovery process. Additionally, in the increasingly networked clinical environment, Web pages, instant messages, videos, scientific imaging, sales and marketing data, collaborative workspaces, and predictive modeling data are likely to be present within an organization, and each source potentially possesses information that can help to better inform specific efforts. Historically, content management solutions that had 21CFR Part 11 capabilities—electronic records and signatures—were focused mainly on content-enabling manufacturing-related processes. Today, life sciences companies have many standalone repositories, requiring different skills, service level agreements, and vendor support costs to manage them. With the amount of content doubling every three to six months, companies have recognized the need to manage unstructured content from the beginning, in order to increase employee productivity and operational efficiency. Using scalable and secure enterprise content management (ECM) solutions, organizations can better manage their unstructured content. These solutions can also be integrated with enterprise resource planning (ERP) systems or research systems, making content available immediately, in the context of the application and within the flow of the employee’s typical business activity. Administrative safeguards—such as content de-duplication—can also be applied within ECM systems, so documents are never recreated, eliminating redundant efforts, ensuring one source of truth, and maintaining content standards in the organization. Putting it in context Consolidating structured and unstructured information in a single system can greatly simplify access to relevant information when it is needed through contextual search. Using contextual filters, results can include therapeutic area, position in the value chain, semantic commonalities, technology-specific factors, specific researchers involved, or potential business impact. The use of taxonomies is essential to organizing information and enabling contextual searches. Taxonomy solutions are composed of a hierarchical tree that defines the relationship between different life science terms. When overlaid with additional indexing related to research and/or business processes, it becomes possible to effectively narrow down the amount of data that is returned during searches, as well as prioritize results based on specific criteria and/or prior search history. Thus, search results are more accurate and relevant to an employee’s day-to-day work. For example, a search for the word "tissue" by a lab researcher would return significantly different results than a search for the same word performed by someone in procurement. Of course, diverse data repositories, combined with the immense amounts of data present in an organization, necessitate that the data elements be regularly indexed and cached beforehand to enable reasonable search response times. In its simplest form, indexing of a single, consolidated data warehouse can be expected to be a relatively straightforward effort. However, organizations require the ability to index multiple data repositories, enabling a single search to reference multiple data sources and provide an integrated results listing. Security and compliance Beyond yielding efficiencies and supporting new insight, an enterprise search environment can support important security considerations as well as compliance initiatives. For example, the systems enable organizations to retain the relevance and the security of the indexed systems, so users can only see the results to which they are granted access. This is especially important as life sciences companies are working in an increasingly networked environment and need to provide secure, role-based access to information across multiple partners. Although not officially required by the 21 CFR Part 11 regulation, the U.S. Food and Drug Administraiton has begun to extend the type of content considered when performing relevant audits and discoveries. Having an ECM infrastructure that provides centralized management of all content enterprise-wide—with the ability to consistently apply records and retention policies along with the appropriate controls, validations, audit trails, and electronic signatures—is becoming increasingly critical for life sciences companies. Making the move Creating an enterprise-wide ECM environment requires moving large amounts of content into a single enterprise repository, a daunting and risk-laden initiative. The first key is to focus on data taxonomy, allowing content to be mapped across systems. The second is to take advantage new tools which can dramatically speed and reduce the cost of the data migration process through automation. Additional content need not be frozen while it is migrated, enabling productivity throughout the process. The ability to effectively leverage information into success has been gaining importance in the life sciences industry for years. The rapid adoption of enterprise content management, both in operational processes as well as in scientific management, are clear indicators that the companies are looking to use all available data to be better informed, improve decision making, minimize risk, and increase time to market, to maintain profitability and be more competitive. As more and more varieties and sources of information are brought under the strategic management umbrella, the ability to divine knowledge from the vast pool of information is increasingly difficult. Simple search engines and basic content management are increasingly unable to effectively extract the right information from the mountains of data available. By bringing these tools into context and integrating them with business processes and applications, we can effectively focus on the right decisions that make our organizations more profitable.

  • My PHP login no longer works

    - by Matt Clayton
    This page worked like a charm for years... enter the correspondng user id and password and you would be redirected to your directory. Now suddenly, all attempts to log in - valid or otherwise - result in the page remaining static... no message, no redirect, nothing. Nothing in the code has changed, it just plain doesn't work anymore. Could this be the result of some kind of change on the server side? Yeah, I know it's not super secure, but it was good enough for our purposes. I'm certainly open to better suggestions. I just need it to work... and keep working. Please be gentle! I know almost nothing of programming.

  • MapRedux - PowerShell and Big Data

    - by Dittenhafer Solutions
    MapRedux – #PowerShell and #Big Data Have you been hearing about “big data”, “map reduce” and other large scale computing terms over the past couple of years and been curious to dig into more detail? Have you read some of the Apache Hadoop online documentation and unfortunately concluded that it wasn't feasible to setup a “test” hadoop environment on your machine? More recently, I have read about some of Microsoft’s work to enable Hadoop on the Azure cloud. Being a "Microsoft"-leaning technologist, I am more inclinded to be successful with experimentation when on the Windows platform. Of course, it is not that I am "religious" about one set of technologies other another, but rather more experienced. Anyway, within the past couple of weeks I have been thinking about PowerShell a bit more as the 2012 PowerShell Scripting Games approach and it occured to me that PowerShell's support for Windows Remote Management (WinRM), and some other inherent features of PowerShell might lend themselves particularly well to a simple implementation of the MapReduce framework. I fired up my PowerShell ISE and started writing just to see where it would take me. Quite simply, the ScriptBlock feature combined with the ability of Invoke-Command to create remote jobs on networked servers provides much of the plumbing of a distributed computing environment. There are some limiting factors of course. Microsoft provided some default settings which prevent PowerShell from taking over a network without administrative approval first. But even with just one adjustment, a given Windows-based machine can become a node in a MapReduce-style distributed computing environment. Ok, so enough introduction. Let's talk about the code. First, any machine that will participate as a remote "node" will need WinRM enabled for remote access, as shown below. This is not exactly practical for hundreds of intended nodes, but for one (or five) machines in a test environment it does just fine. C:> winrm quickconfig WinRM is not set up to receive requests on this machine. The following changes must be made: Set the WinRM service type to auto start. Start the WinRM service. Make these changes [y/n]? y Alternatively, you could take the approach described in the Remotely enable PSRemoting post from the TechNet forum and use PowerShell to create remote scheduled tasks that will call Enable-PSRemoting on each intended node. Invoke-MapRedux Moving on, now that you have one or more remote "nodes" enabled, you can consider the actual Map and Reduce algorithms. Consider the following snippet: $MyMrResults = Invoke-MapRedux -MapReduceItem $Mr -ComputerName $MyNodes -DataSet $dataset -Verbose Invoke-MapRedux takes an instance of a MapReduceItem which references the Map and Reduce scriptblocks, an array of computer names which are the remote nodes, and the initial data set to be processed. As simple as that, you can start working with concepts of big data and the MapReduce paradigm. Now, how did we get there? I have published the initial version of my PsMapRedux PowerShell Module on GitHub. The PsMapRedux module provides the Invoke-MapRedux function described above. Feel free to browse the underlying code and even contribute to the project! In a later post, I plan to show some of the inner workings of the module, but for now let's move on to how the Map and Reduce functions are defined. Map Both the Map and Reduce functions need to follow a prescribed prototype. The prototype for a Map function in the MapRedux module is as follows. A simple scriptblock that takes one PsObject parameter and returns a hashtable. It is important to note that the PsObject $dataset parameter is a MapRedux custom object that has a "Data" property which offers an array of data to be processed by the Map function. $aMap = { Param ( [PsObject] $dataset ) # Indicate the job is running on the remote node. Write-Host ($env:computername + "::Map"); # The hashtable to return $list = @{}; # ... Perform the mapping work and prepare the $list hashtable result with your custom PSObject... # ... The $dataset has a single 'Data' property which contains an array of data rows # which is a subset of the originally submitted data set. # Return the hashtable (Key, PSObject) Write-Output $list; } Reduce Likewise, with the Reduce function a simple prototype must be followed which takes a $key and a result $dataset from the MapRedux's partitioning function (which joins the Map results by key). Again, the $dataset is a MapRedux custom object that has a "Data" property as described in the Map section. $aReduce = { Param ( [object] $key, [PSObject] $dataset ) Write-Host ($env:computername + "::Reduce - Count: " + $dataset.Data.Count) # The hashtable to return $redux = @{}; # Return Write-Output $redux; } All Together Now When everything is put together in a short example script, you implement your Map and Reduce functions, query for some starting data, build the MapReduxItem via New-MapReduxItem and call Invoke-MapRedux to get the process started: # Import the MapRedux and SQL Server providers Import-Module "MapRedux" Import-Module “sqlps” -DisableNameChecking # Query the database for a dataset Set-Location SQLSERVER:\sql\dbserver1\default\databases\myDb $query = "SELECT MyKey, Date, Value1 FROM BigData ORDER BY MyKey"; Write-Host "Query: $query" $dataset = Invoke-SqlCmd -query $query # Build the Map function $MyMap = { Param ( [PsObject] $dataset ) Write-Host ($env:computername + "::Map"); $list = @{}; foreach($row in $dataset.Data) { # Write-Host ("Key: " + $row.MyKey.ToString()); if($list.ContainsKey($row.MyKey) -eq $true) { $s = $list.Item($row.MyKey); $s.Sum += $row.Value1; $s.Count++; } else { $s = New-Object PSObject; $s | Add-Member -Type NoteProperty -Name MyKey -Value $row.MyKey; $s | Add-Member -type NoteProperty -Name Sum -Value $row.Value1; $list.Add($row.MyKey, $s); } } Write-Output $list; } $MyReduce = { Param ( [object] $key, [PSObject] $dataset ) Write-Host ($env:computername + "::Reduce - Count: " + $dataset.Data.Count) $redux = @{}; $count = 0; foreach($s in $dataset.Data) { $sum += $s.Sum; $count += 1; } # Reduce $redux.Add($s.MyKey, $sum / $count); # Return Write-Output $redux; } # Create the item data $Mr = New-MapReduxItem "My Test MapReduce Job" $MyMap $MyReduce # Array of processing nodes... $MyNodes = ("node1", "node2", "node3", "node4", "localhost") # Run the Map Reduce routine... $MyMrResults = Invoke-MapRedux -MapReduceItem $Mr -ComputerName $MyNodes -DataSet $dataset -Verbose # Show the results Set-Location C:\ $MyMrResults | Out-GridView Conclusion I hope you have seen through this article that PowerShell has a significant infrastructure available for distributed computing. While it does take some code to expose a MapReduce-style framework, much of the work is already done and PowerShell could prove to be the the easiest platform to develop and run big data jobs in your corporate data center, potentially in the Azure cloud, or certainly as an academic excerise at home or school. Follow me on Twitter to stay up to date on the continuing progress of my Powershell MapRedux module, and thanks for reading! Daniel
