  • Virtual Pageview Goal Funnel Not Tracking Correctly

    - by cphill
    I have an AJAX form that has three stages: 1. The landing page where a user fills out a form and selects between three question sets and clicks begin assessment 2. The assessment page, where users fill out questions relating to the question set that they selected on the landing page. 3.The results page, which shows whether they are at High Risk or Low Risk. Since this is an AJAX form that does not open a new page for each step of the process, I implemented a virtual pageview that would fire on the pageload of each step of the form process. The following is my virtual pageview setup for each stage: /form/begin-assessment /form/assessment/* (* = Three different virtual pageviews depending on the users selection of the three sets of questions: /one, /two, /three) 3./form/finished-assessment I have set up three separate goals to track user progress through each step of the form assessment. Here is my Goal setup: Goal Description: -Goal Type: Destination Goal Details: -Destination: /form/finished-assessment -Funnel: On Step 1: /form/begin-assessment (Required: Yes) Step 2: /form/assessment/one (Step 2: replace /one with /two or /three and you have my two other goals setup) Now my goals are recording the correct data in the first step and show the completions in the destination, but the second step does not show any drop offs. They show the same data as the destination. Any ideas of how I set up the goals wrong?

  • Memory limiting solutions for greedy applications that can crash OS?

    - by Hooked
    I use my computer for scientific programming. It has a healthy 8GB of RAM and 12GB of swap space. Often, as my problems have gotten larger, I exceed all of the available RAM. Rather than crashing (which would be preferred), it seems Ubuntu starts loading everything into swap, including Unity and any open terminals. If I don't catch a run-away program in time, there is nothing I can do but wait - it takes 4-5 minutes to switch to a command prompt eg. Ctrl-Alt-F2 where I can kill the offending process. Since my own stupidity is out of scope of this forum, how can I prevent Ubuntu from crashing via thrashing when I use up all of the available memory from a single offending program? At-home experiment*! Open a terminal, launch python and if you have numpy installed try this: >>> import numpy >>> [numpy.zeros((10**4, 10**4)) for _ in xrange(50)] * Warning: may have adverse effects, monitor the process via iotop or top to kill it in time. If not, I'll see you after your reboot.

  • Office 2010 always reconfiguring itself on startup

    - by Rhys Gibson
    I've just installed Office 2010 Professional Plus (upgrading from Office 2007). It works fine under my admin account, but when I login with my wifes non-admin account, every time I open a document or start an app (Word, Excel, Publisher ...) Office 2010 goes through its configuration process (starting the the standard install dialog and then running the bootstrap process) before it loads the app - which wastes 2-3 minutes. Once it's done this, the app runs fine and I can make setting changes that are remembered when it restarts, but I can't work out why it thinks it needs to configure the app each time. Any thoughts?

  • Microphone crackling in Ubuntu 12.04

    - by Tomas
    I am not very experienced in linux and have this problem with microphone which works fine on Windows. Microphone is external one and when listening to recorded sound (both Sound Recorder and Skype Echo Test) you can hear crackling noise. I fixed output crackling by replacing load-module module-hal-detect with load-module module-hal-detect tsched=0 in /etc/pulse/default.pa but I have no idea how to fix input. Hardware info: Card: HDA ATI SB Chip: Realtek ALC272X Thanks for help!

  • How can I programmatically change the keyboard layout?

    - by Jason R. Coombs
    I want to run a shell command or script that will configure each of my Ubuntu Precise boxes to use the Dvorak keyboard layout as the default (and only) layout. With earlier versions, I was able to set the XKBVARIANT in /etc/default/keyboard but when I make this change in Precise (and reboot), the keyboard layout appears to be unaffected (both in console and in gnome). I tried also setting the XKBMODEL to pc105 and XKBLAYOUT to us, but that did not seem to help. I know I can set the layout for gnome using the 'keyboard layout' tool... but I want the change to affect the console, and I want to automate the process. How can I accomplish this? Edit: To clarify, I want to know how I can cause to change (using only a script or command-line) the keyboard layout to be Dvorak as the default and only keyboard layout for both Gnome and the console. I want this change to be persistent (survive reboots), just as it is when the change is made through the Keyboard Layout tool. Edit: Let me put it another way. If I had installed the operating system myself (which I did not because the OS was installed by the virtual machine infrastructure), I could have selected the desired keyboard layout at install time, and that layout would be applied persistently, system-wide. How can I change the layout to appear as if I had set it during the install process?

  • Large file copy from NFS to local disk performance drop

    - by Bernhard
    I'm trying to copy a 200GB file from an NFS mount to a local disk. The local disk is an XFS filesystem on a LVM on top of a RAID 5 system (hardware RAID controler). I'm using rsync to monitor the transfer speed. At the beginning the IO speed is about 200MB/s, stable for the first 18GB. But then the performance drops by a factor of 10-20 and never recovers to the initial rate. Sometimes it reaches about 50-100MB/s but just for a few seconds and then the process seems to hang for a bit. At the same time all file-stat operations on the target filesystem are blocking for a long time (minutes). Also interrupting the copy process blocks for several minutes, a sub-sequent delete of the partly copied file takes also several minutes. Any ideas what could be causing this?

  • Likeliness of obtaining same IP address after restarting a router

    - by ?affael
    My actual objective is to simulate logged IPs of web-site users who are all assumed to use dynamically assigned IPs. There will be two kinds of users: good users who only change IP when the ISP assignes a new one bad users who will restart their router to obtain a new IP So what I would like to understand is what assignment mechanics are usually at work here deciding from what pool of IPs one is chosen and whether the probability is uniformly distributed. I know there is no definite and global answer as this process can be adjusted be the ISP but maybe there is something like a technological frame and common process that allows some plausible assumptions. UPDATE: A bad user will restart the router as often as possible if necessary. So here the central question is how many IP changes on average are necessary to end up with a previously used IP.

  • Where can I find ready to use windows scripts that used robocopy?

    - by Geo
    We are installing the Windows Resource Kit, and that installs RoboCopy. We want to have access to a few windows scripts that uses RoboCopy so we can start from those to build something else. Any ideas on where I can find a few samples? NOTE 1: A bit of information. Every time we try to copy D drive to E drive (new drive) we get an error that says: ERROR 32 (0x000000020) Copying File d:\pagefile.sys The process cannot access the file because it is being used by another process. Waiting 30 seconds. Just to help figure it out.

  • Partition/install issues

    - by jalal ahmad
    I am new to Ubuntu and tried to install 10.1 as dual boot option from a USB. At first I encountered the error when in partition dialogue of installation process that cannot find root directory. I did a search on Ubuntu forums and did this as in one of the posts. Make sure that the partition file system you wish to install Linux, Ubuntu or Backtrack on it is ext4, ext3 or ext2, and not FAT32 or NTFS. Then mount / on it: During the installation process press "change" on the partition you wish to use Make sure "do not use this partition" scroll is not chosen, scroll to ext4, ext3 or ext2 On the "mount" field write / Click ok, then next a message will appear saying something like "swap area was not defined, do you wish to continue or choose a swap area?", click "ok" and continue or click "go back" and choose another partition and click change, on the file system scroll choose "swap" and click "ok" and next All good but when I rebooted I could not find Windows vista as in dual boot option. Plus I could not see wireless networks and in the process of trying to find out what went wrong the soft switch somehow turned off and as I cannot boot in Windows I have no idea what to do. Again searching internet I found a post which said the dual boot problem can be overcome by installing gparted but when I tried I got the message Reading package lists... Done Building dependency tree Reading state information.. Done E: Couldn't find package gparted I thought I am going to copy my stuff from my hard disk and try to install Windows but I found out that I have two partitions which are different from what I had before installing Ubuntu. I now have filesystem partition1 119 GB ext4, swap partition 5 1.1 GB swap and extended partition 2 1.1 GB. And I cannot mount 119 GB where all my personal videos, photos are if still there. Now I cannot boot from Windows even. Need help on what to do? Best case scenario would be to be able to copy my stuff before I mess up the system further. Else a dual boot system and if not then how do I install vista again. I have Windows CD. Cheers guys and thanks in advance.

  • Time Capsule With Raspberry Pi

    - by Richard Jones
    So I have a Raspberry PI, with an 1TB external USB HD plugged into it. I have Debian Wheezy installed to which I added the NetaTalk package. Following this guide which is on Ubuntu, but was easy enough to understand - http://kremalicious.com/ubuntu-as-mac-file-server-and-time-machine-volume/ I was even able to change the icon to look like an X-Serve :-) Next step to add a second HD that will backup my Windows 8 laptop as well.

  • Why does the CPU usage reach 100% when laptop is plugged in?

    - by Mayank
    I have an HP Elitebook 8440p with Windows 7 Ultimate, i7 Processor and 8 GB RAM. For the last couple of days, when I plug-in my laptop for charging, the CPU usage shoots up to 100% and remains there for around 15 minutes. No offending process shows up in Task Manager/Process Explorer but the laptop is practically unusable for that time. The CPU usage becomes normal when I remove the power cord but shoots up again when plugged back. This is happening with different power adapters/wall sockets so it might not be a faulty adapter issue. Why is this happening and any pointer to resolve this issue?

  • TransformXml Task locks config file identified in Source attribute

    - by alexhildyard
    As background: the TransformXml MSBuild task is typically invoked in a custom build step to mark up a web.config file with per-environment configuration; its flexible directives offer highly granular control over the insertion, removal, substitution and transformation of existing configuration hierarchies. For those using the TransformXML task (typically in a Web Deployment Project) I raised an issue against Visual Studio 2010, in which the file handle on the input file was not released, meaning that following transformation the source file remained locked. As a result, the best way to transform a file was first to rename it, transform it, and then copy it back, leaving the "locked" file to be freed up later.I just heard today that this has now been resolved in Visual Studio 2012 RTM. That's good news, because Web Config Transformations offer a lot. An intelligent, automated build process will swap in the relevant transform(s), making it much easier to synthesise the Developer and Build server builds. This makes for a simpler and more exemplary build process, and with the tighter coupling comes a correspondingly quicker response to Developmental change.Oh, and don't forget -- it isn't just web.configs you can transform. You can transform app.configs, or indeed any XML file that honours the task's schema and hierarchical rules.

  • Empty sshd_config file

    - by Thomas
    I run a Centos 5 server with a LAMP stack. I was told this morning that the server was down not serving web content. I then tried to restart httpd but it failed due to another process was listening on port 443. I checked what process was running on 443 using netstat and it was sshd. I then checked the sshd_config file to check the ports that sshd was running on but the sshd_config file was completely blank. I than ran chkrootkit and it flagged not suspicions. What could of caused the sshd_config file to be blank, and sshd service to be restarted? I would really value your thoughts. All the best.

  • Issue with Toshiba Satellite C50 A-1JM

    - by Nathan Hawkes
    I am having some odd problems with my Toshiba laptop. For the last two days, it has not loaded past the boot screen for hours, if at all. When I force the laptop off and switch it back on, it goes to the Preparing Automatic Repair process but will not complete the process and go to the desktop. However, this only happens when the battery is plugged in. When I remove the battery and run the laptop on power, it works without issue. Would this be a battery issue (given it works without the battery) or a hard drive issue (given it won't get past the boot screen)? If neither, what would you suggest as a solution?

  • PHP hits 100% CPU and eats RAM at the same time Monday to Friday

    - by Daniel Samuels
    We run a learning platform for primary schools here in the UK and it's all been running extremely well. However at around 4PM Monday to Friday we see the same issue arise -- 1-2 PHP threads will spike to 100% CPU and gradually start eating up RAM until the server(s) fall over. 98%+ of our requests are HTTPS, these come into our Layer 7 load balancer which then decrypts the SSL data, adds the X-HTTP-Forwarded-For header and forwards the data onto an application server (we have 2 of those at the moment) on port 80. Our application servers have Varnish on port 80 which takes in the request from the load balancer and passes the request through to Nginx on port 81. Nginx then works out which 'vhost' it needs to use and passes any PHP processing through to PHP-CGI which is listening on a socket (managed through spawn-fcgi). There's an instance of Memcached running too, MySQL runs on a separate server / slave setup. Throughout the day the load will typically go no higher than 0.8 on either of the application servers, however at around 4PM our problem arises. I've managed to run strace on a few of the actual threads when they cause the problem and I always see the same thing: stat("/usr/share/zoneinfo/Europe/London", {st_mode=S_IFREG|0644,st_size=3661, ...}) = 0 stat("/usr/share/zoneinfo/Europe/London", {st_mode=S_IFREG|0644,st_size=3661, ...}) = 0 This is repeated infinitely and never stops until you SEGKILL the process or oomkiller kills it. There are no cron jobs scheduled to run at that time and I don't have any way of seeing exactly what Nginx request is associated with the PHP process which is running. We are running PHP 5.3.14 which we upgraded to from 5.3.8 last week to rule out the older version being the problem. This issue has been going on a few months now and we have no idea what is causing it. We deploy our software very frequently, so it's difficult to track down a specific release which may have started the problem - especially as we do not know the date of the first occurrence of this issue. Varnish is version 3.0.1, Nginx is 1.0.6 (which I understand is about a year old now), our servers are running CentOS release 5.7 (Final) they have Intel i3 540s at 3.07Ghz and 8GB of RAM. There's a discussion on the Debian mailing list about something very similar, you can find that here. Has anyone seen anything like this in the past, does anyone have any ideas or suggestions? Are there a way of linking an Nginx request directly to a PHP thread? Is there a better way of seeing what the PHP process is doing? (I've seen GDB mentioned, though I'll have to recompile PHP) Thanks!

  • Hidden Gems: Accelerating Oracle Data Integrator with SOA, Groovy, SDK, and XML

    - by Alex Kotopoulis
    On the last day of Oracle OpenWorld, we had a final advanced session on getting the most out of Oracle Data Integrator through the use of various advanced techniques. The primary way to improve your ODI processes is to choose the optimal knowledge modules for your load and take advantage of the optimized tools of your database, such as OracleDataPump and similar mechanisms in other databases. Knowledge modules also allow you to customize tasks, allowing you to codify best practices that are consistently applied by all integration developers. ODI SDK is another very powerful means to automate and speed up your integration development process. This allows you to automate Life Cycle Management, code comparison, repetitive code generation and change of your integration projects. The SDK is easily accessible through Java or scripting languages such as Groovy and Jython. Finally, all Oracle Data Integration products provide services that can be integrated into a larger Service Oriented Architecture. This moved data integration from an isolated environment into an agile part of a larger business process environment. All Oracle data integration products can play a part in thisracle GoldenGate can integrate into business event streams by processing JMS queues or publishing new events based on database transactions. Oracle GoldenGate can integrate into business event streams by processing JMS queues or publishing new events based on database transactions. Oracle Data Integrator allows full control of its runtime sessions through web services, so that integration jobs can become part of business processes. Oracle Data Service Integrator provides a data virtualization layer over your distributed sources, allowing unified reading and updating for heterogeneous data without replicating and moving data. Oracle Enterprise Data Quality provides data quality services to cleanse and deduplicate your records through web services.

  • Optimizing perceived load time for social sharing widgets on a page?

    - by Lucka
    I have placed the facebook "like" and some other social bookmarking websites link on my blog, such as Google Buzz, Digg, Twitter, etc. I just noticed that it takes a while to load my blog page as it need to load the data from the social networking sites (such as number of likes etc). How can I place the links efficiently so that first my blog content loads, and meanwhile it loads data from these websites -- in other words, these sharing widgets should not hang my blog page while waiting for data from external sites?

  • Different bounding volumes for culling and collision detection

    - by Serthy
    Should an object in a 3D-engine use different bounding volumes for collision-detection (broad-phase) and culling? Basically class renderBounds and class physBounds versus class boundingVolume? Each of this classes then could either contain the same type of volumes (AABB's, kDOP's, sphere's etc.) or a special fitting one for the particular object. (note: without considering of using an external physics engine)

  • SQL Server Migration Assistant for Oracle problem

    I've recently installed SSMA on my computer and after connecting to both the Oracle instance (which holds the database to be converted) and the SQL Server. I've mapped the needed schemas from oracle to mssql. The problem is that when i click on the report button for the assessment report there's an error popping up: Assesment Error : Nothing to Process The output window states: Starting conversion... Analyzing metadata... Conversion finished with 0 errors, 0 warnings, and 0 informational messages. There is nothing to process. Has anyone got experience with SSMA. I can't figure out what I am doing wrong. Thank you.

  • Distributing application updates using SCCM 2007

    - by theraneman
    Hi all, If there are any System Center Config Manager (SCCM) users out there, please clarify my doubt here. I have used the ConfigMgr console to distribute a custom application to a client machine. Now I need to distribute some updated files of that application. Isnt's it possible to add those files in the same package source used earlier and advertise again? Or should I use the SCCM software update section for this? Not sure if its only me, but the Software distribution process looks much easier than the Software Updates process in SCCM 2007. Please do let me know if there any online tutorials which explain how to update a custom application. Any help much appreciated.

  • When does a "scripter" become a "programmer"?

    - by makerofthings7
    Is there a difference between 'scripters' and 'programmers'? What is the dividing line between scripters and programmers? Perhaps all scripters be considered to be a programmer. If not all scripters can fall into the same camp, what about those people who use external objects such as COM objects, Win32's, etc. via an interop library? As far as script languages I'm thinking of are (but not limited to) perl, bash, javascript, powershell, and batch files.

  • How to connect to database on remote server

    - by user137263
    Where there is VPN to remote server and then access to the database via local network interface, how can one establish a remote link between one's computer (with a programme such as Visual Studio 2010) and SQL Server (e.g. 2008 R2) ? Any attempts to create a direct link to the SQL Server are blocked. Whilst the SQL Server can be configured to allow external access, this provides its own host of problems. Any help would be much appreciated.

  • Is chroot the right choice for my use case?

    - by Anthony
    Backstory: I am working on setting up a MineCraft server and want to allow admins to have ssh access to the MineCraft server console and appropriate mc server files, but not the whole system. The console provided by the minecraft server is only available to the user that launched the process. In addition, the admins will need terminal access to some basic cli tools such as wget, cp, mv, rm, and a text editor. Plan: I have already setup the ssh aspect of things, requiring pre-shared keys and whatnot. Setup a jailed environment in which all user activity will be contained. Setup user accounts. - The first user account will be the minecraft user. The minecraft user will start the MC server in a multiuser screen session and allow the other admins to attach to it. - Subsequent users should have their own /home directory for normal usage. Setup acl for the appropriate files to allow each user to edit the mc server files. No one will be doing system updates, nor will anyone be installing any programs, so I'll be the only user with sudo. The Issues: I don't want the ssh users to have access to the whole system. Users will still need to use wget or curl to update the mc server files. Is chroot the right tool for this use case, or is there something more appropriate for the job? I have no experience setting up a chroot environment and have found several tools to aid in this process. Jailkit seems to be the most robust, but it's not in the standard repos.
