  • Stop Windows 7 from forcefully shutting itself down when waiting to update

    - by Kenneth
    I have had this happen to me twice now. I'll be in the middle of working on something that has resulted in me not rebooting my machine for several days. If Windows 7 is waiting to install updates it'll eventually get to a point where it forces a restart to install the updates. The problem is that it doesn't notify me or tell me that its going to do this and I've lost work as a result and most recently had a VM become corrupt and unusable. Is there a way to at least get it to prompt me before doing this? It used to...

  • Should all my files be stored on my shared partition?

    - by James
    I am setting up a tripple boot HD and was going to use a 4th partition to share files between OS's. I was wondering if there is any point in having much space on each OS partition to store files or if I just make the shared partition big and put everything on that? Is there any difference in speed between accessing files on the shared partition vs the native files? Are there any other benefits/disadvantages of having files on either the native/shared partition? EDIT: OS's in question are Windows 7, Ubuntu 12.04, and OS X 10.7.4.

  • Virtual hosts and subdomains, need configuring on live, not on dev

    - by rix
    I have a query about subdomains and virtual hosts. On my dev server, I ca nset up a new virtual hosts and point it to a subdomain, ie: newdomain.mydevserver.com All is fine and I can access 'newdomain/mydevserver/com' I can also do 'host newdomain.mydevserver.com' However, when I do the same with my main server I get the server couldn't be contacted error - I'm guessing that's because i need a cname or a record for the DNS. My question is, why does it seem that i can create subdomains on my dev but not on my live server? Help appreciated, many thanks!

  • Are there design patterns or generalised approaches for particle simulations?

    - by romeovs
    I'm working on a project (for college) in C++. The goal is to write a program that can more or less simulate a beam of particles flying trough the LHC synchrotron. Not wanting to rush into things, me and my team are thinking about how to implement this and I was wondering if there are general design patterns that are used to solve this kind of problem. The general approach we came up with so far is the following: there is a World that holds all objects you can add objects to this world such as Particle, Dipole and Quadrupole time is cut up into discrete steps, and at each point in time, for each Particle the magnetic and electric forces that each object in the World generates are calculated and summed up (luckily electro-magnetism is linear). each Particle moves accordingly (using a simple estimation approach to solve the differential movement equations) save the Particle positions repeat This seems a good approach but, for instance, it is hard to take into account symmetries that might be present (such as the magnetic field of each Quadrupole) and is this thus suboptimal. To take into account such symmetries as that of the Quadrupole field, it would be much easier to (also) make space discrete and somehow store form of the Quadrupole field somewhere. (Since 2532 or so Quadrupoles are stored this should lead to a massive gain of performance, not having to recalculate each Quadrupole field) So, are there any design patterns? Is the World-approach feasible or is it old-fashioned, bad programming? What about symmetry, how is that generally taken into acount?

  • How to sync bookmarks between Firefox, Chrome, and Safari on multiple computers?

    - by Tai Squared
    There are some similar question on bookmark syncing, but most answers point to Delicious or Google bookmarks. However, as Chrome doesn't have the Google toolbar, how would those sync? I use several computers and different browsers on them so I would like a easy solution to keep all of the bookmarks in sync on various computers and browsers in the same organizational structure throughout. Also, I would prefer to have my bookmarks only synced to my account, not necessarily visible to the whole world as on Delicious. Is there any service that could handle this?

  • How to make Chrome open bookmarks and URLs in new tabs?

    - by MBraedley
    I principally use Firefox both at home and at work, but on occasion I use Chrome. I have Firefox working the way I like it by having it open bookmarks in a new tab when left clicked, as well, URLs open in new tabs. Although having URLs open in a new tab can be annoying if I type a bad URL, I still prefer it, but that's neither here nor there. I would like to replicate this behaviour in Chrome, and can't seem to find anything relavent in the settings. Is there any way of doing this without an extension? If not, can you point me towards an appropriate extension (I've already done a search and can't find what I'm looking for)?

  • Hostmonster can't change domains around?

    - by loneboat
    (question imported from http://superuser.com/q/204439/53847 ) Horrible title, but I couldn't think of a succinct way to summarize it to fit. I have HostMonster for my web hosting. I have several domain names under the same account (using the same web space, IP address, etc...). Every HM account has one domain set up as the "main domain", and all other domains are "secondary". The only way I have ever encountered this being an issue is in trying to use HTTPS - since (from my limited understanding) HTTPS encrypts headers, you can't route HTTPS requests to different virtual hosts on a server - only unencrypted requests, since it must look in the request to know where to route it. When I registered for my account, I only had one domain name (A). I have since added domain names (B), (C), (D), etc... At one point I switched domain name (B) to be my "main" domain name - so I could use HTTPS with it. I have since sold domain name (B), and would like to make domain name (A) my "main" one again (as it was before), but HM support says, "no, once a domain name has been a 'main' domain name on an account once, we can't set it up to be a 'main' domain name again. You're welcome to use domains (C), or (D), though.". They tell me the only way to reuse domain (A) as a "main" domain would be to set up a new account and transfer over all my files. I'm confused here. If I have domains (D), (E), and (F), they say I'm welcome to make one of them my new main domain name, just never (A) again, since I've already "used" it once. Calls to support only reveal that they can't let me do it because doing so would somehow "break" my account. Can anyone think of any good reason why this should be so? The only thing I can think is that maybe they're using the domain names as keys in some database or something? But if that's the case, that's ridiculous - they need to reorganize their databases!

  • Handling deleted users - separate or same table?

    - by Alan Beats
    The scenario is that I've got an expanding set of users, and as time goes by, users will cancel their accounts which we currently mark as 'deleted' (with a flag) in the same table. If users with the same email address (that's how users log in) wish to create a new account, they can signup again, but a NEW account is created. (We have unique ids for every account, so email addresses can be duplicated amongst live and deleted ones). What I've noticed is that all across our system, in the normal course of things we constantly query the users table checking the user is not deleted, whereas what I'm thinking is that we dont need to do that at all...! [Clarification1: by 'constantly querying', I meant that we have queries which are like: '... FROM users WHERE isdeleted="0" AND ...'. For example, we may need to fetch all users registered for all meetings on a particular date, so in THAT query, we also have FROM users WHERE isdeleted="0" - does this make my point clearer?] (1) continue keeping deleted users in the 'main' users table (2) keep deleted users in a separate table (mostly required for historical book-keeping) What are the pros and cons of either approach?

  • Deleting Time Machine in Mac OS X 10.6.4

    - by cappuccino
    Does anyone know how to delete Time Machine in Mac OS X 10.6.4? Before answering: sudo rm -rf /whateverthetimemachineis does not work Disabling the ACL permissions first with sudo fsaclctl -p /whatever -d does not work, sudo: fsaclctl: command not found Use the delete all backup feature in Time Machine... this is slow as hell, would take days. Need a command line solution. No I don't want to reformat the drive, I have other content on it, and no don't say I should have separated on two partition or two drives, I did it this say since partitions cannot be dynamically changed, and two drives is annoying since, whats the point of having a big drive?... plus has no relation to the issue at hand. Already googlied for hours and read everything on Super User, nothing working. and all solutions are the first 4. Any clues?

  • Connection String Incorrectly Formatted [migrated]

    - by Randy E
    I'm running into some issues. Every time I launch into debug mode and hit the "Create User" button, I'm getting an exception being thrown that is due to the Connection String either being in the wrong syntax or just wrong. Using Visual Studio 2010, project is .NET 3.5 with SQL 2008 Express. This is just a personal project that I'm testing some other things with, I know this generally isn't the recommended format but for a personal small project, I don't see the point in doing it any other way. The things I'm testing actually work :) Data Source=.\SQLEXPRESS;AttachDbFilename=|Data Directory|ASPAppDatabase.mdf;Integrated Security=True;User Instance=True That doesn't work. Data Source=.\SQLEXPRESS;AttachDbFilename="|Data Directory|ASPAppDatabase.mdf";Integrated Security=True;User Instance=True Neither does that. Data Source=.\SQLEXPRESS;AttachDbFilename='|Data Directory|ASPAppDatabase.mdf';Integrated Security=True;User Instance=True And again, neither does that :/ However, rather than using "|Data directory| if I use the full path to the local DB file it works just fine and no exception is thrown, and I can read and write as I need. And just to cover all my bases, here is the button click event that creates the User. protected void btnAddUser_Click(object sender, EventArgs e) { Membership.CreateUser(txtUserName.Text, txtPassword.Text); btnLogin_Click(sender, e); } So, what am I missing in regards to the |Data Directory|? Here is an example of the above not working correctly..taken directly from web.config. <add name="ASPAppDatabaseConnection" connectionString='Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|ASPAppDatabase.mdf;Integrated Security=True;User Instance=True'/>

  • Capturing BizTalk 2004 SQLAdapter failures

    - by DanBedassa
    I was recently working on a BizTalk 2004 project where I encountered an issue with capturing exceptions (inside my orchestration) occurring from an external source. Like database server down, non-existing stored procedure, …   I thought I might write-up this in case it might help someone …   To reproduce an issue, I just rename the database to something different.   The orchestration was failing at the point where I make a SQL request via a Response-Request Port. The exception handlers were bypassed but I can see a warning in the event log saying: "The adapter failed to transmit message going to send port "   After scratching my head for a while (as a newbie to BTS 2004) to find a way to catch the exceptions from the SQLAdapter in an orchestration, here is the solution I had.   ·         Put the Send and Receive shapes inside a Scope shape ·         Set the Scope’s transaction type to “Long Running” ·         Add a Catch block expecting type “System.Exception” ·         Set the “Delivery Notification” of the associated Port to “Transmitted” ·         Change the “Retry Count” of the associated port to 0 (This will make sure BizTalk will raise the exception, instead of a warning, and you can capture that) ·         Now capture and do whatever with the exception inside the Catch block

  • Robocopy to copy only new folders and files

    - by Valery Shampal
    A task: To find all new files and subfolders under some root folder (let us say Documents) and to copy them to other disk (j: in this case) Command line used: robocopy c:\users\valery\documents j:\robocopy /XO /E /MAXAGE:20131030 /XD Result: A full folders tree created. Only new files copyed, as supposed. It's good A point is, that I do not want to create all subfolders on a target disk, if there are no new files in them. Results are exeptable, but there is a lot of work to go through all folders and to find new files, as well, as to understand, what subfolders are a new ones Regards, Valery

  • Should I make a seperate unit test for a method, if it only modifies the parent state?

    - by Dante
    Should classes, that modify the state of the parent class, but not itself, be unit tested separately? And by separately, I mean putting the test in the corresponding unit test class, that tests that specific class. I'm developing a library based on chained methods, that return a new instance of a new type in most cases, where a chained method is called. The returned instances only modify the root parent state, but not itself. Overly simplified example, to get the point across: public class BoxedRabbits { private readonly Box _box; public BoxedRabbits(Box box) { _box = box; } public void SetCount(int count) { _box.Items += count; } } public class Box { public int Items { get; set; } public BoxedRabbits AddRabbits() { return new BoxedRabbits(this); } } var box = new Box(); box.AddRabbits().SetCount(14); Say, if I write a unit test under the Box class unit tests: box.AddRabbits().SetCount(14) I could effectively say, that I've already tested the BoxedRabbits class as well. Is this the wrong way of approaching this, even though it's far simpler to first write a test for the above call, then to first write a unit test for the BoxedRabbits separately?

  • Two users using the same same user profile while not in a domain.

    - by Scott Chamberlain
    I have a windows server 2003 acting as a terminal server, this computer is not a member of any domain. We demo our product on the server by creating a user account. The person logs in uses the demo for a few weeks and when they are done we delete the user account. However every time we do this it creates a new folder in C:\Documents and Settings\. I know with domains you can have many users point at one profile and make it read only so all changes are dumped afterwords, but is there a way to do that when the machine is not on a domain? I would really like it if I didn't have to remote in and clean up the folders every time.

  • print job doesn't go to print queue

    - by flatsguide
    I have two printers hooked up to my intel imac. I am having a printing error. It seems that whenever i try to print (a simple text doc) I am unable to get the print job to go to print queue with one of my printers. I have a HP c7280 and a HP c3100. I am able to get one working properly, but the other doesn't seem to allow it to go to the print queue. I have switched usb cables (with the printer that I know works) and both printers are recognized by the computer in the printer preferences pane. I've tried reseting the printer system in the printer setup utility.. reloaded the drivers from HP.. etc. If anyone has a suggestion or could point me to a little help i'd be VERY grateful Best Regards..

  • I Can't run the Netbeans but I installed successfully

    - by David
    I'm new to Ubuntu as well as Netbeans. I installed Netbeans, and I've made sure to install all the JDKs and JREs I could find. It installed without errors. I also saw this question and made sure I followed all the instructions there as well. I never got any error messages of any kind. So far as I know, it installed okay. However, when I try to run Netbeans, I get the message in the bottom of the Netbeans IDE like this: ant -f /root/NetBeansProjects/samp1 -Djsp.includes=/root/NetBeansProjects/samp1/build/web/one.jsp -DforceRedeploy=false -Dclient.urlPart=/one.jsp -Ddirectory.deployment.supported=true -Djavac.jsp.includes=org/apache/jsp/one_jsp.java -Dnb.wait.for.caches=true run /root/NetBeansProjects/samp1/nbproject/build-impl.xml:774: The libs.CopyLibs.classpath property is not set up. This property must point to org-netbeans-modules-java-j2seproject-copylibstask.jar file which is part of NetBeans IDE installation and is usually located at <netbeans_installation>/java<version>/ant/extra folder. Either open the project in the IDE and make sure CopyLibs library exists or setup the property manually. For example like this: ant -Dlibs.CopyLibs.classpath=a/path/to/org-netbeans-modules-java-j2seproject-copylibstask.jar BUILD FAILED (total time: 0 seconds)

  • WinXP workgroup, 3 routers 3 computers

    - by Silvera
    I have 3 computers with WinXP x86, and 3 Cisco 1800 series routers. I'm trying to create a workgroup so that the 3 computers can share files with eachother. They can ping eachother (without any internet connection), and the routers setup is correctly configured (with interfaces, ip adresses, and ports). But none of the computers can see eachother, even though they are on the same network. My first question would be - can it be done the way it is currently configured - and, if yes, how, or can anyone point me in the right direction?

  • bash terminal/console strange overlapping behavior

    - by UpKey
    I am using gnome-terminal in Ubuntu 11.10 and seem to get long lines overlapping in the terminal window. When I copy a long command line and paste it into the terminal, the text gets overlapped to the start of the line and often covers the user prompt. If I resize the terminal window, making it wider the overlapping gets undone and everything looks normal. In previous versions of Ubuntu, if a line was too long it would continue on the next line below. Another problem I have noticed that may be related, is when using the up arrow key to show previously typed commands, sometimes instead of the output command line being replaced by the previous command each time the key is pressed, the lines get partially merged. A portion of the old line remains, and the next command gets joined onto the end. This leftover part of a command is persistent and does not get replaced next time the key is pressed, although the insertion point or blinking cursor is at the end of the latest recalled command, and the leftover has no effect if I press enter. Is this problem a bug or some setting that needs fixing? Where do I look for the cause? keyboard? gnome-terminal? bash? Thank you for any help or suggestions offered

  • Is it safe to use consumer MLC SSDs in a server?

    - by Zypher
    We (and by we I mean Jeff) are looking into the possibility of using Consumer MLC SSD disks in our backup data center. We want to try to keep costs down and usable space up - so the Intel X25-E's are pretty much out at about 700$ each and 64GB of capacity. What we are thinking of doing is to buy some of the lower end SSD's that offer more capacity at a lower price point. My boss doesn't think spending about 5k for disks in servers running out of the backup data center is worth the investment. Just how dangerous of an approach is this and what can be done to mitigate these dangers?

  • How to check use of userva boot option on Win 2K3 server

    - by Tim Sylvester
    I have some 32-bit Win2K3 servers running an application that fails now and then apparently due to heap fragmentation. (Process virtual bytes grows, private bytes does not) I do not have access to the source code or build process of this application. I have modified the boot.ini file on one of these servers to include /userva=2560, half way between the normal mode of operation and the /3GB option. Normally it takes weeks to reach the point of failure, but I'd like to see right away whether this has actually had any effect. As I understand it, this option limits the kernel to the remaining address space (1536MB instead of 2048), but does not necessarily give an application the extra address space, depending on the flags in the application's PE header. How can I determine whether the O/S is allowing a particular application, running in production, to access address space above 2GB? Additionally, what's the best way to monitor the system to ensure that the kernel is not starved for address space, and more generally how should I go about finding the optimal value for this setting?

  • Cisco 2911 - problem with DHCP

    - by bluszcz
    Hi, i am configuring DHCP daemon on Cisco 2911. At some point i assigned address 192.168.50.50 to one box (using MAC address 'relation'). When I wanted to saved config - I got warning, that address 192.168.50.50 is already in Pool, which sounds bit weird - it was first host which I started configuring. I tried with following commands: clear ip dhcp server statistics clear ip dhcp conflict but first one doesn't output anything (and show statistics shows that there are 2 addresses in pool), and second one throws "there is no conflicted ips" message. How I can force/purge/clear/allow to bind 192.168.50.50 to this box?

  • Cannot add Windows 7 client to SBS 2008

    - by Sandokan
    I have just installed SBS 2008 R2 Standard on VMware Workstation 9 along with Windows 7 Pro N. Both are activated and running fine. I have followed the steps to configure SBS 2008 and am now at the point where I'm to add a computer to the domain. Here is where the problem begins. I have gone through the steps of using the webinterface. On the client I downloaded Launcher.exe. I then run it and get the error "Check computer requirements - Failed" (translated from swedish): "This computer doesn't reach the requirements for connecting to the network." "The computer doesn't reach the maximum requirements for the operating system with regards to connect to the network" The provided link for More information only leads to a general supportpage and doesn't handle this specific error. I have also checked the time settings and they are correct. Any clue as to what this problem could be?

  • Grub2 attempting to boot hd1 when it should boot hd0

    - by JoBu1324
    I'm attempting to perform a "normal" install on a USB3 SSD (I don't know if it is noteworthy, but I don't have a swap partition). The installation proceeds normally (I'm installing from a USB2 device I created using LiLi Boot, with a copy of Ubuntu 12.10 64bit that I downloaded directly from the source. The system I'm running Ubuntu on has had a more traditional installation of ubuntu running on it without issue (also 12.10), so I know that everything works A-OK when booting from a 7200RPM internal disk. There are a number of oddities that I've noticed so far, including graphics corruption, but the first and most pressing issue is that Grub2 refuses to recognize the correct hd. From /boot/grub/grub.cfg: if [ x$feature_default_font_path = xy ] ; then font=unicode else insmod part_msdos insmod ext2 set root='hd1,msdos1' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd1,msdos1 --hint-efi=hd1,msdos1 --hint-baremetal=ahci1,msdos1 b58ee4f7-d41d-400a-b7b8-18bd1f0ae9d3 else search --no-floppy --fs-uuid --set=root b58ee4f7-d41d-400a-b7b8-18bd1f0ae9d3 fi font="/usr/share/grub/unicode.pf2" fi This is from a 100% fresh install of linux (first boot), which was installed while no hard drives were connected to the system, other than the USB2 LiLi drive. The system refuses to boot unless I change the hd1,msdos1 - hd0,msdos1 in the grub menu at boot, when it is the only disk device connected to the PC. What options are left for me to troubleshoot this issue? I've been racking my brains and taxing the internet trying to dig up something on this problem, but now I'd like to see if the Ubuntu community can rise to the challenge and help me fix this boot problem. This is the second time I've attempted this particular setup. The first time, after days of wasted time, I managed to get it to boot every other boot - i.e. every even boot it would boot into Ubuntu like it was happy; every odd boot it would boot into the BusyBox or Grub prompt. At one point it complained that it couldn't find /dev/disk/by-uuid/[the disk], which I found most perplexing, since the disk was there and booted before and after the occurrence (with intervention).

  • Apache crashing at random intervals. Can not find a reason in log files

    - by Nick Downton
    We are having an issue with a VPS running plesk 9.5 on ubuntu 8.04 At seemingly random intervals Apache will disappear and needs to be started manually. I have checked the apache error log, /var/log/messages, individual virtual host apache error files and cannot find anything that coincides with the time of the failure. dmesg is empty which is a bit odd. We have also had the psa service go down for no apparent reason but apache stay up. I'm at a loss to diagnose this really because all the log files I can find do not point to any issues. Are there any others I can look at? Memory usage sits at about 55% (out of 400mb) and it isn't a particularly high trafficed server. Any pointers as to where else I can find out what is going on would be very much appreciated. Nick

  • How to factorize code in Unreal Kismet (i.e. "Material Function"s for Kismet)

    - by Georges Dupéron
    In the Unreal Development Kit, when using the Material Editor, one can factorize frequently-used groups of nodes by creating a Material Function (content Browser ? right-click ? new matrial function, IIRC). When defining the behaviour of some actor in Kismet, one can easily have a dozen nodes involved. If I have many actors that share the same behaviour, then I'll copy-paste these nodes, and change the variables so they point to the other actors. This leads to inconsistencies (a modification in the behaviour of an actor isn't propagated in the copy-pasted nodes), complexity (you end up with hundreds of nodes), and generally useless effort. My question is : Can I create a "kismet function", just like a material function ? Note: I'd rather avoid using UnrealScript. I don't even know where to type UnrealScripts, don't know where the documentation is and more generally don't have enough time to invest in learning UnrealScript. This "kismet function" feature must be usable by graphists (with little programming knowledge). If a (simple) script suffices to add this feature in the Kismet editor, so that one can create several "functions" without using UnrealScript, then fine, but I don't really want to have to write a script each time I want to factorize a few nodes. Thanks for any information !
