  • Change the location of the System Temp directory on Windows 2003 Server

    - by skylarking
    In order to update an application on a Windows 2003 Server box, the application calls for 2.0 GB of free space in the System's Temp directory. The OS is on C:\ , and there is only 1 GB of free space there.... The server has a RAID configuration for its data on the system's E:\ . There is over 100GB of free space on E:\ . When I did a set tmp I found that the system's TEMP directory is not surprisingly located on C:\ .... TMP = C:\DOCUME~1\ADMINI~1.DES\LOCALS~1\Temp I assume it is possible to change the System Temp directory to the be located on E:\ ? How is this done, where's a good place to stick it, and is it safe to do this ?

  • new vhost - main host AWstats

    - by vn
    Hi, I just began working at this new job and I have to config a new host for stats with awstats. I once used awstats on my own server, no biggie. Now, I'm on a multi-sites server with the acces_log files nicely splitted. I copied a awstats.conf file from one of the sites that already has (working) stats. I changed the LogFile and SiteDomain values as mentioned from http://awstats.sourceforge.net/docs/awstats_setup.html#BUILD_UPDATE, saved the conf and ran the commands perl awstats.pl -config=mysite -update and perl awstats.pl -config=mysite -output -staticlinks awstats.mysite.html (yes I changed it with my infos...) PROBLEM IS : whenever I try to access the html file or the dynamic page (with the config option on awstats.pl like my working site does), I get the stats of the MAIN site from access.log itself (and not access_log-mysite) from what it says at the top of the page and from the hostname on the left tab (stats for mysite.com)... what did I do wrong? There's no errors from what I see... Thanks a lot for any help

  • The mouse pointer in my Ubuntu VM has turned into a little hand with a document, and clicks are igno

    - by Daryl Spitzer
    The mouse pointer in my Ubuntu 8.04.3 LTS VM (running in VMware Fusion) has changed into a little hand holding a document. It doesn't show up in screen-shots. All mouse clicks (left or right) are ignored. But I can still type in the one Terminal window I have open. (And commands work fine.) I wonder if I'm in some kind of drag-and-drop mode. How do I get out of this? Update: Rebooting (from the command-line) worked. Ubuntu came up with the regular mouse-pointer.

  • How can I pretty print erb in BBedit indenting rails tags and not just markup?

    - by Andres Diez
    I want to re-indent my code but the rails tags <% foo %> get aligned to the left with no indentation. What I'm using is: markup utilities format pretty print Does anyone know if there is a way to reconfigure this behavior? UPDATE: I just found this out but cant seem to get it working: "The 'Pretty print' option for Markup - Utilities - Format is now implemented internally using a Dreamweaver-style source format profile. This affords slightly prettier output than was possible before. Advanced users can override the factory format profile by placing an appropriately constructed file at ~/Library/Application Support/BBEdit/SourceFormat.profile." I opened the bbedit app package, found the file, copied it to the folder indicated in "application support" and tweaked the desired indentation width just as a test before touching anything else, and it doesnt seem to do anything.

  • How do you cope with change in open source frameworks that you use for your projects?

    - by Amy
    It may be a personal quirk of mine, but I like keeping code in living projects up to date - including the libraries/frameworks that they use. Part of it is that I believe a web app is more secure if it is fully patched and up to date. Part of it is just a touch of obsessive compulsiveness on my part. Over the past seven months, we have done a major rewrite of our software. We dropped the Xaraya framework, which was slow and essentially dead as a product, and converted to Cake PHP. (We chose Cake because it gave us the chance to do a very rapid rewrite of our software, and enough of a performance boost over Xaraya to make it worth our while.) We implemented unit testing with SimpleTest, and followed all the file and database naming conventions, etc. Cake is now being updated to 2.0. And, there doesn't seem to be a viable migration path for an upgrade. The naming conventions for files have radically changed, and they dropped SimpleTest in favor of PHPUnit. This is pretty much going to force us to stay on the 1.3 branch because, unless there is some sort of conversion tool, it's not going to be possible to update Cake and then gradually improve our legacy code to reap the benefits of the new Cake framework. So, as usual, we are going to end up with an old framework in our Subversion repository and just patch it ourselves as needed. And this is what gets me every time. So many open source products don't make it easy enough to keep projects based on them up to date. When the devs start playing with a new shiny toy, a few critical patches will be done to older branches, but most of their focus is going to be on the new code base. How do you deal with radical changes in the open source projects that you use? And, if you are developing an open source product, do you keep upgrade paths in mind when you develop new versions?

  • Unity isn't starting on 13.10 (with Cinnamon 2.0 installed)

    - by Sam Pearman
    Since upgrading to 13.10, I can't log in to unity desktop. Light dm works correctly, but attempting to log in tries to start the session then drops back to light. I've already dropped to terminal (ctrl+alt+f2) and done this: sudo apt-get update sudo apt-get install --reinstall ubuntu-desktop sudo apt-get install unity Logging in as a guest session also fails. Logging in to other window managers works with varying degrees of success. Note: I have Cinnamon 2.0 installed from PPA. I'm using a 2 monitor setup. Also of note is that the session prior to my upgrade to 13.10 the background of unity failed to display at all, instead showing what was there in the screen buffer from the previous frame. The entire OS worked correctly otherwise though, so I just ignored it for the session. No other upgrades or even updates were done prior to this occurring. My upgrade path to 13.10 was basically this: Install 13.04 alongside Windows 7, use ubuntu as a glorified web browser for a while, get updates (in preparation for 13.10), install 13.10. I also used Unity Tweak Tool to change some aspects of unity, particularly auto-hide. Any help or ideas would be appreciated, as I'm typing this on my phone :(

  • how to troubleshoot sql server issues

    - by joe
    i have an ASP .net application with sql server database, and i am wondering if you can give your ideas on how to troubleshoot the following issue: i can insert / update / delete from any table, but i have one page that uses transactions to insert into different tables. the c# code is correct and very simple, but it fails. i used the sql profiler to see how my app interacts with the DB, especially that the app is using stored procedures, i can catch the exec procedure statement and run it manually from SSMS and it works fine, but the same stored procedure fails from the application!!! which lead me to think that issue is coming from the user account and settings, i am no expert in sql server and wondering if anyone can explain how to verify the required settings for user account. thanks EDIT: in web.config here is how i reference my connection <connectionStrings> <add name="Conn" connectionString="Data Source=localhost;Initial Catalog=myDB;Persist Security Info=True;User ID=DbUser;Password=password1254_3" providerName="System.Data.SqlClient"> </connectionstring> EDIT: i will try to describe the process here: 1- i begin a transaction 2- i call a stored proc to insert (which succeeds) and return the scope identity ( that will be used in the next step) 3- i call another stored procedure to insert some more info + scope identity from step 2, which is a foreign key here 4- i get error, foreign key violation 5- transaction rolled back, now tables empty again... thanks

  • SqlServer2005 Enterprise Fast Recovery, SqlAgent Availability, and Replication

    - by automatic
    I have a database under SqlServer2005 Enterprise 64bit sp3, that is in phase 3 of 3 of recovery after a reboot without normal shutdown. It looks like with fast Recovery, the database became available when recovery moved into phase 3. However, it seems (based on message in SqlAgent log), that SqlAgent is "started" but not available to run jobs until recovery completes. I have other databases on the same server that are transactional publications. It seems to me that if I let users update the published databases, transactions will start to build up in the log, but won't be moved to the distribution database or onto the subscribers because SqlAgent isn't running jobs. Should I be overly concerned about performing updates before

  • Authentication system brainstorm

    - by gansbrest
    Hi. We got multiple small websites (microsites) and one main high traffic one with big users base. Right now the requirement is to build authentication system which should allow users to loign with the same identity across the network. All website are running on different domains, powered by Drupal 6 CMS and have separate databases (so sharing tables with prefix is not an option + it creates a huge mess in the db). Here is the set of core requirements I came up with: Users should be able to login with the same credentials to all sites within the network User’s data sharing between Main site (storage) and all micro sites within the network Data synchronization across the network when user changes the data (update email or password for example) The login/registration process should be seamless and consistent Register on any of the sites across the network and use that identity to login later on. In the future there might be a need to add openid authentication options. Basically we are looking at something similar stackexchange does, but not sure if they have central users base on not. I was thinking about custom solution which will include 2 parts (modules), one will be stored on the Main site for users data storing and responding to requests from clients. Second part (module) will be placed on each microsite, which is going to send requests to the Master. Some kind of client - server setup. One of the complications I see right away is #3. Data Synhcronization across the network. I just don't want to reinvent the wheel and maybe some work is already done in this direction. Looking forward to your ideas on how to approach this project. EDIT: We use MySQL database

  • Install gcc on Ubuntu 12.04 LTS

    - by Brian M. Hunt
    When I try to install gcc on Ubuntu 12.04 LTS Server with apt-get install gcc, I get the following error: The following packages have unmet dependencies: gcc : Depends: cpp (>= 4:4.6.1-2ubuntu5) but it is not going to be installed Depends: gcc-4.6 (>= 4.6.1-1) but it is not going to be installed Recommends: libc6-dev but it is not going to be installed or libc-dev When I delve deeper (i.e. try to apt-get install gcc-4.6), I get: gcc-4.6 : Depends: gcc-4.6-base (= 4.6.1-9ubuntu3) but 4.6.3-1ubuntu5 is to be installed Depends: cpp-4.6 (= 4.6.1-9ubuntu3) but it is not going to be installed Depends: libgomp1 (>= 4.6.1-9ubuntu3) but it is not going to be installed Depends: libquadmath0 (>= 4.6.1-9ubuntu3) but it is not going to be installed Recommends: libc6-dev (>= 2.13-0ubuntu6) but it is not going to be installed So when I try to install gcc-4.6=4.6.1-9ubuntu3 I get a list of 366 packages to remove (including e.g. apt). Which is craziness. This is an essentially vanilla installation of Ubuntu 12.04 LTS Server (i.e. I installed nginx, python-flup, python-yaml, rsync, python-pkg-resources, lsof, fontconfig, iptables, ufw, scons, and grc). It is very surprising to me that I cannot install gcc, so I am somewhat confused as to why attempting to install gcc fails. The only apparent fix would seem to be uninstalling 366 packages, many of which are central to the operation of Ubuntu. Something doesn't add up, and I would be very grateful for assistance. EDIT The above is with the latest packages of course, having used apt-get update; apt-get upgrade before attempting the above. Sorry, I should have mentioned that.

  • Small change in MVVM Light Toolkit templates for Blend 4 RC

    - by Laurent Bugnion
    Ah, the joy of new releases… You will find that the MVVM Light Toolkit works fine with Visual Studio 2010 RTM and Blend 4 RC except for a few adjustments: Blend templates The path to the Expression Blend 4 project templates changed. If you start Expression Blend 4 RC now, you will likely not see the MVVM Light templates in the New Project dialog.   New Project dialog with MVVM Light To restore the templates, follow the steps: Open Windows Explorer Navigate to C:\Users\[username]\Documents\Expression (or simply type My Documents in Windows Explorer and then open the Expression folder). Change the name of the “Blend 4 beta” folder into “Blend 4”. That’s it, you should now see the templates in the New Project dialog in Blend 4. Note that since the new name is “Blend 4”, I hope that I won’t need to do the same exercise when Blend 4 RTM is released! Windows Phone 7 templates Since the Windows Phone 7 tools are not ready yet for Visual Studio 2010 RTM and Blend 4 RC, the templates in the Silverlight for Windows Phone folders will not work. You will get an error if you try to create a new such project in the newly released environment. I hesitated to remove these templates from the current packages, but honestly that is a lot of trouble for a very short time before the tools for Windows Phone 7 are released (note: I don’t have any information as to when these tools will be released). In the mean time, just don’t create a WinPhone7 application. Reminder: If you want to write code for Windows Phone 7, you need to keep the Visual Studio 2010 RC as well as Expression Blend 4 beta. Updated package I uploaded an update to the Blend 4 templates. It is available like before on the “Install manually” page and on the Codeplex page.   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

  • Show which modifier keys are pressed during screen recording?

    - by Jenko
    I'd like to see which modifier keys I've pressed during screen recordings so my students can understand what keys I've pressed while I click and drag. Is there any software that can do this? I'm aware that Windows 7 does this internally, if there's a way to enable it. Windows 7 When you have a Wacom tablet connected to your PC, or if you have a Tablet PC, windows shows little yellow tip bubbles whenever you press modifier keys. Any way to enable these on a normal PC? Update: I've tried starting the Tablet PC Input Service but nothing happens. The Tablet PC Settings dialog has nothing interesting either. Is there a registry setting I can tweak?

  • In the days of modern computing, in 'typical business apps' - why does performance matter?

    - by Prog
    This may seem like an odd question to some of you. I'm a hobbyist Java programmer. I have developed several games, an AI program that creates music, another program for painting, and similar stuff. This is to tell you that I have an experience in programming, but not in professional development of business applications. I see a lot of talk on this site about performance. People often debate what would be the most efficient algorithm in C# to perform a task, or why Python is slow and Java is faster, etc. What I'm trying to understand is: why does this matter? There are specific areas of computing where I see why performance matters: games, where tens of thousands of computations are happening every second in a constant-update loop, or low level systems which other programs rely on, such as OSs and VMs, etc. But for the normal, typical high-level business app, why does performance matter? I can understand why it used to matter, decades ago. Computers were much slower and had much less memory, so you had to think carefully about these things. But today, we have so much memory to spare and computers are so fast: does it actually matter if a particular Java algorithm is O(n^2)? Will it actually make a difference for the end users of this typical business app? When you press a GUI button in a typical business app, and behind the scenes it invokes an O(n^2) algorithm, in these days of modern computing - do you actually feel the inefficiency? My question is split in two: In practice, today does performance matter in a typical normal business program? If it does, please give me real-world examples of places in such an application, where performance and optimizations are important.

  • How can I perform 2D side-scroller collision checks in a tile-based map?

    - by bill
    I am trying to create a game where you have a player that can move horizontally and jump. It's kind of like Mario but it isn't a side scroller. I'm using a 2D array to implement a tile map. My problem is that I don't understand how to check for collisions using this implementation. After spending about two weeks thinking about it, I've got two possible solutions, but both of them have some problems. Let's say that my map is defined by the following tiles: 0 = sky 1 = player 2 = ground The data for the map itself might look like: 00000 10002 22022 For solution 1, I'd move the player (the 1) a complete tile and update the map directly. This make the collision easy because you can check if the player is touching the ground simply by looking at the tile directly below the player: // x and y are the tile coordinates of the player. The tile origin is the upper-left. if (grid[x][y+1] == 2){ // The player is standing on top of a ground tile. } The problem with this approach is that the player moves in discrete tile steps, so the animation isn't smooth. For solution 2, I thought about moving the player via pixel coordinates and not updating the tile map. This will make the animation much smoother because I have a smaller movement unit per frame. However, this means I can't really accurately store the player in the tile map because sometimes he would logically be between two tiles. But the bigger problem here is that I think the only way to check for collision is to use Java's intersection method, which means the player would need to be at least a single pixel "into" the ground to register collision, and that won't look good. How can I solve this problem?

  • What are the best Microsoft Certifications to start with?

    - by emragins
    Background I have a bachelors in math and a certification. in C++ from 2007. Since then I've spent a lot of time working with python, C#, and started going through the ASP.NET certification materials. I'm starting to realize that the certification is going to take longer than anticipated and I'm not sure I want to spend the next 4-5 months studying before I have it completed. Most of resume shows teaching/tutoring experience with some low-level administration thrown in. Question If I want to get any programming position, which certifications would be best to start with? What would be the quickest and easiest to obtain, yet represent value for my employer? Are certifications even the way to go? If not, what would you suggest? Update I have several programs that I show off when I can (mostly games), and I'm about 75% through a C# application I hope to have done in the next week. Since most employers simply ask for a resume and not samples, what would be the best way to present the work to them?

    I just upgraded to 8.1 and now none of the Metro apps start. The issue is that if I start any metro app, including the Store and PC Settings they immediately fail. The classic desktop is fine, as are standard programs, it's just the metro apps. If I look in the system event log I see errors like this: *Activation of application winstore_cw5n1h2txyewy!Windows.Store failed with error: This application does not support the contract specified or is not installed. See the Microsoft-Windows-TWinUI/Operational log for additional information.* In addition the tiles in metro have a small cross icon on them: I suspect that my Live ID (which I somehow managed to skip during update) is not set properly and consequently none of the online stuff works. But how do I fix this? I can't start PC settings, I can't start store. I see no way in the classic desktop of setting these things. I don't want to have to reinstall for this. Is there a simple fix?

  • Skip "Sign in to your Microsoft account" (Windows 8.1 Setup)

    - by noloader
    I have an RT tablet and updated it to Windows 8.1. The update basically performs the new PC setup. I can't get past the "Sign into your Microsoft Account". Clicking "Next" does not allow me to proceed (and prompts me for an email address). Clicking "Don't have an account" does nothing because its not linked. The other two options are "Create an account" a "Privacy statement". I don't want to create an account, and I'm not interested in their perverted terms of service for an account. In Windows 8.0, we were given the option to use local authentication. How do I bypass this feature?

  • How to set up Dell OMSA tools on Debian 6 (Squeeze) (PE2950)

    - by javano
    I assume I have set up them up incorrectly or am missing a library or dependency. When I log into the OMSA web interface I can't see anything Also, omreport tells me nothing; root@box:~# omreport storage controller No controllers found I assume these two will use the same source of information so what ever is wrong will fix them both. I set up OMSA as per these instructions. Also I have compiled MegaCLI (as this is a PowerEdge 2950 with a Perc 6/i controller) and I have used that to update the RAID firmware, so that works, but the Dell tools aren't. What have I missed during set up? root@kvm1:~# cat /etc/issue Debian GNU/Linux 6.0 \n \l root@kvm1:~# uname -a Linux kvm1.mivoice.cust.vostron.net 3.4.9 #1 SMP Wed Aug 22 19:08:46 BST 2012 x86_64 GNU/Linux

  • Why does 'top' say my machine is only 50% idle?

    - by Chris Moore
    What's going on here? I'm running nothing on the system, iotop and iftop show the network and hard drive are both idle, and top (sorted by %CPU) shows nothing running. So why is the system only 50% idle? What's the other 50% waiting for?

That almost always causes everything to lock up, so I'm guessing that's the problem. I'll reboot and stop using mount.cifs.

  • Ubuntu 9.10 X Stuck in restart loop - I think...

    - by widgisoft
    Trying out Ubuntu, installation went fine - upgraded to the proprietary nVidia drivers but on restart I get a login prompt and the screen is flashing really fast almost as if Xserver is trying to start and failing, I can type when the screen isn't in a "flash" as it were and it's so fast and random it's hard to even type a login name without it missing some characters - this makes typing a password (i.e. not being able to see which characters made it or not) very hard. I can log back into the live cd and alter my settings - but I can't even find out how to stop X stop starting on boot; Looks like they've moved everything around :-p I'd like to: Stop X from crashing and going insane (if it is actually Xserver) Know how to stop X from starting on bootup, Looks like interactive boot is also off by default now Update: A temporary work around seems to be enabling ssh and just connecting to the box over the network - ssh seems to work fine :-p Cheers, Chris

  • best way to enlarge system partition

    - by yuvi
    I have a problem - I need to enlarge my system partition. I mean - when I initially installed Ubuntu, I split the partition so I have 15GB for system and the rest (around 400) pointed at /home/. This is very useful if anything goes wrong someday and I want to format and completely re-install Ubuntu without losing any of my actual data. The problem is, 15GB isn't enough, so it seems. I already moved /var/ and /opt/ folder to /home/, adding symlinks at root, but I'm still at 86% usage and I'm having performance issues (mostly when booting or running a VM). I can use Ubuntu on a flash drive and externally enlarge the partition, but I'm really afraid with going forward with that plan. Also, despite what I said before, I'd like to avoid re-installing the system if at all possible. Any advice, suggestions or ideas on how to best approach this? Any warnings I should heed? Thanks in advance! update Here's the gparted screenshot - as you can see, there's windows on dual boot (sda1-5 are all related to the windows system), then I have a linux swap, 14GB (so uh... not even 15) of system and 435 of for /home.
