  • Why does my screen dim on a desktop installation of Windows 7?

    - by Robert Cartaino
    Periodically, while using my Windows 7 Pro desktop installation, the screen suddenly dims. The brightness is about 75% normal (estimate). It's as if I am in a power-saving mode on a laptop running on batteries. But this is a full desktop installation. I know it is not a hardware glitch or monitor adjustment issue because the Windows cursor is still bright white while everything else goes dim. The Control Panel Power Options have not been changed. They are set to "Balanced [active]" and I have tried restoring the default settings. Flipping through the power and display settings, everything looks "normal." There is no screen saver or power-off-after settings apparent. Rebooting the system resets everything to full brightness but I can't find a way to restore it in Windows or to keep it from happening in the first place. Suggestions?

  • How do you troubleshoot Family Safety reports

    - by Klas Mellbourn
    I have set up Microsoft Family Safety in Windows 8 for my daughter's account. At first I got meaningful reports via e-mail each week. But then the e-mails started reporting no activity, even though my daughter still uses the computer. The e-mails are still sent to me, but indicate that she is not using the computer at all. Family Safety is definitely still active on the computer. It limits how long she can use the computer. So only the e-mail reports are buggy. I don't know how to troubleshoot this since the e-mails are generated by Microsoft. Any ideas?

  • Using inheritance and polymorphism to solve a common game problem

    - by Barry Brown
    I have two classes; let's call them Ogre and Wizard. (All fields are public to make the example easier to type in.) public class Ogre { int weight; int height; int axeLength; } public class Wizard { int age; int IQ; int height; } In each class I can create a method called, say, battle() that will determine who will win if an Ogre meets and Ogre or a Wizard meets a Wizard. Here's an example. If an Ogre meets an Ogre, the heavier one wins. But if the weight is the same, the one with the longer axe wins. public Ogre battle(Ogre o) { if (this.height > o.height) return this; else if (this.height < o.height) return o; else if (this.axeLength > o.axeLength) return this; else if (this.axeLength < o.axeLength) return o; else return this; // default case } We can make a similar method for Wizards. But what if a Wizard meets an Ogre? We could of course make a method for that, comparing, say, just the heights. public Wizard battle(Ogre o) { if (this.height > o.height) return this; else if (this.height < o.height) return o; else return this; } And we'd make a similar one for Ogres that meet Wizard. But things get out of hand if we have to add more character types to the program. This is where I get stuck. One obvious solution is to create a Character class with the common traits. Ogre and Wizard inherit from the Character and extend it to include the other traits that define each one. public class Character { int height; public Character battle(Character c) { if (this.height > c.height) return this; else if (this.height < c.height) return c; else return this; } } Is there a better way to organize the classes? I've looked at the strategy pattern and the mediator pattern, but I'm not sure how either of them (if any) could help here. My goal is to reach some kind of common battle method, so that if an Ogre meets an Ogre it uses the Ogre-vs-Ogre battle, but if an Ogre meets a Wizard, it uses a more generic one. Further, what if the characters that meet share no common traits? How can we decide who wins a battle?

  • Windows 2003 - logging off the Administrator account makes web applications inaccessible

    - by Saravana
    Consider a web application installed on a Windows Server 2003 SP2 machine with the admin account. The application is accessible in the server as well as in the network when at least one session of the admin account is logged in. If there are no active sessions of the admin account, the web application is not accessible via the network, nor accessible locally when logged in with another user account. What would cause the web application to be inaccessible there's no Administrator session? Please suggest anything that might help find the solution.

  • Can't select hard disk off Windows 7 system image creator

    - by David
    When I try to create a system image in Windows 7 from the Control Panel (Control Panel\All Control Panel Items\Backup and Restore) I get the option to select a hard disk or a removeable disk to select, I have 2 disks and wanted to create the image on my spare one. However when I click refresh it doesn't show either of my disks but shows my CDROM under the removable disks area, anyone have this problem? Also, when I select a USB disk instead, it tries to iamge both my disks! I can't select my active Windows 7 installed disk! How pointless!

  • Why isn't 'ether proto \ip host host' a legal tcpdump expression?

    - by Ezequiel Garzon
    In its description of valid tcpdump expressions, the pcap-filter man pages state: The filter expression consists of one or more primitives. Primitives usually consist of an id (name or number) preceded by one or more qualifiers. In turn, these qualifiers are type, dir and proto. So far so good, but further down we find this: ip host host which is equivalent to: ether proto \ip and host host In the first case, ip and host are, respectively, proto and type. What pattern does ether proto \ip follow? Isn't that, as a whole, a proto qualifier? If so, why isn't (a properly escaped) 'ether proto \ip host host' legal (no and)?

  • How can I use 2 monitors plus laptop with my Dell e6420 w/ Nvidia nvs 4200m

    - by KallDrexx
    I have just hooked up a 2nd external monitor to my Dell e6420 laptop with a Nvidia NVS 4200m graphics card, running Windows 8 64 bit. However, the computer won't let me have both monitors and the laptop display active at the same time. I installed the latest Nvidia graphics drivers (310.70) but it claims that my GPU can only support up to 2 monitors. Nivdia's website implies differently (as does various other laptops around the office). The monitors are connected both via DVI to my dell docking station that has multiple DVI ports. Both monitors are working correctly, I just can't get all 3 working together. Attempting to download the driver from dell fails, as their driver installer is broken apparently Any ideas?

  • Public IP shows strange characters and Facebook registers logged-in session to a different location

    - by Stuart Kershaw
    I'm encountering some IP strangeness today and hoping to find an explanation. In short, I'm based in Seattle, WA with my ISP being Comcast. While browsing Facebook's account settings, I noticed that my active session was located to Mount Laurel, NJ. At that point I ran a search in Google for 'my public IP', which returned an interesting result: a string of characters in the following format: 2601:8:b000:xxx:xxxx:xxxx:xxxx:xxxx Normally, a search for my IP returns something like: 67.xxx.xx.xxx A phone call to Comcast got me nowhere, but using Comcast's phone-menu debugging tools, I was able to send a 'refresh signal' to my modem. After that, the search for 'my public IP' yielded the expected result... for about 5 minutes, and then it returned to the new string of characters. Does anyone know of an explanation for this?

  • Tab Completion In Emacs shell-mode SSH Sessions

    - by Sean M
    My current use pattern of emacs results in my having several shell-mode buffers open, each running an ssh session. I am running into an issue with this, though - when I try to tab-complete file names and other things in my remote session, the shell attempts to use completions available on the local machine instead of on the remote machine. For example, if the file ~/foobar exists on the local machine and ~/frob exists on the remote machine, typing in ~/f and pressing tab results in ~/foobar instead of completing correctly. If I use ssh outside of emacs and try the same thing, I get the correct completion of ~/frob instead. How can I get tab-completion to complete the way it does in normal ssh sessions ?

  • Performance improvements of VBulletin by integrating the plugins

    - by reggie
    I have amassed quite a lot of plugins and code that is being hooked into VBulletin's plugin system. There are good uses for this system. But since I am now locked in with the VB 3 branch and it is no longer updated, I wonder what kind of performance improvements I would see if I integrated all the plugins into the vbulletin files and turned the plugin system completely off. My site has about 1.5 mio posts, about 100,000 threads, 100,000 members (of which 10,000 are "active"). I estimate I have about 200 plugins from different products in the plugin manager. Has anybody ever tried this move and could share the experiences?

  • Chrome - Why am I automatically authenticated to a web app even after clearing browser cookies?

    - by Howiecamp
    I am accessing a web application using Chrome. If I sign out of the app and clear all Chrome history/cookies/etc (even Flash cookies which are now handled by Chrome in the same Clear History area) and then re-access the site, I am automatically logged in without being prompted for credentials. I then launched Chrome in Incognito mode and was able to reproduce the same behavior. However, the I was prompted upon the first logon while in Incognito mode. The web application behaves as expected in Internet Explorer 10. Some info about the application: It's a Sharepoint site using NTLM authentication The credentials are Active Directory-based, as the username is domain\username My connection is over the Internet and there is no AD relationship between my local Windows account, my Windows PC. In other words I (meaning my locally logged on user and my PC) are not in any way part of their AD domain. The site is running SSL on port 443 Why might Chrome be automatically authenticating me?

  • Windows Event Viewer - XML Custom Filter

    - by Frank
    <QueryList> <Query Id="0" Path="Application"> <Select Path="Application"> *[EventData[Data and (Data="Error")]] </Select> </Query> </QueryList> I believe the above XML custom filter would work if I wanted to check for Events where "Data" equals the word "Error". However, what I want to express is that I want the Events where Data CONTAINS the word "Error" . . . how do I express that? I've Goggled around, but I can find no references to Regular Expression like pattern matching in the Event Viewer. XPath has "contains", but if Event Viewer will support it, I cannot seem to figure out the syntax for invoking it.

  • UNIX "find" command, match literal "dot"

    - by Robottinosino
    I need files ending with ".pdf" or ".png"; here's my attempt: find /Users/robottinosino/Desktop/_PublishMe_ -type f -regex '.*[pdf|png]' this incorrectly includes files ending with "Apdf", "Zpdf", etc. (missing literal dot before file extension) I tried adjusting the pattern to: find /Users/robottinosino/Desktop/_PublishMe_ -type f -regex '.*\.[pdf|png]' but then no results are returned. Escaping the . with a backslash does not work. Why?

  • Control Targeted Browser Window

    - by Brent Arias
    When I have multiple browser windows open, I don't know how to control which is chosen to open a new link - when that link is selected in a non-browser application. For example, when I click a web link in OneNote or Word, the already-open browser that is chosen is whichever one of my Internet Explorer windows happens to have the least number of open browsing tabs. I would like to change that behavior. I'd like that each newly opened page, as selected from a non-browser app, always goes to the last internet explorer window I had active. Can this be done?

  • Identify Long Running or Slow PHP Scripts

    - by Kirk
    I have web server that is getting around 25K visits a day up at yougetsignal.com. Sometimes the site feels a bit sluggish. I am hosting it on nginx with php5-fpm. Is there a way for me to see a list of all of the long running requests that are coming to the site? I'd love to have a real-time list of all of the active requests that PHP is handling and how long they have been running. Kind of like top, but just for the web server. This would let me know how long requests are taking and which script is the culprit. Anyone have any ideas on how I can do this?

  • CPU sometimes hangs at 50% maximum on Windows 8

    - by Martin.
    Recently I installed Windows 8 on my HP ProBook 6450b and it appears I've got problems when using more than one program at once. Sometimes, when I run multiple programs at once, CPU hangs at 49% and never goes up. I suspect it has something to do with CPU throttling, because sometimes it just goes over 49%. I've got my notebook connected to charger and my plan is set to "Active cooling". The weird thing is that this happens only occasionally. I found nothing in my BIOS that could change this kind of things.

  • Create Virtual Image of Laptop before Formatting

    - by Simon Mark Smith
    I have a 3 year old laptop running Windows XP that I used for business. Although I have not used the laptop in over a year, I now want to re-commission it with Windows 7 and a fresh install. Before I do the fresh install I want to create a Virtual Image of the laptop that I can keep and potentially run on my desktop machine should I ever need to access any of the old files/projects that it contains currently. I know that most people will say just copy the files over to your desktop, but my concern is the configuration of the laptop. I used to use it for development and it has older versions of Visual Studio, SQL Server, Active X controls etc, etc than I currently use so I really want to preserve the environment not just the files. So really I am asking what is the best tool-set/method to achieve this? I understand there are free VM tools available but I have never done this before and would appreciate any help.

  • Baffling Exchange 2010 issue , Outlook 2003

    - by Nick Weber
    Recently we upgraded from Exchange 2003 to Exchange 2010. The Exchange 2003 server is still up and active with a handful of users still there we are planning on migrating. Also we have mobile devices and a Blackberry BES server setup publishing to Exchange 2010 public folders free busy. The unfortunate issue is majority of our clients are still Outlook 2003. The issue seems to be hit and miss but sometime clients cannot view other client’s calendars. They get (cannot refresh free/busy) when they add another user and check their available times. This is also true with booking resources (conference rooms) . One thing we noticed is that the Blackberry BES seems to have created its own free/busy folders, so we have some users who use the BES on free/busy folder and other users who don’t use the BES on other free/busy folders. If any of the clients log-in via “Exchange 2010” web-access or with a Outlook 2007 client they can view the calendaring just fine. Thanks for your help Nick @Toshana

  • Getting spurious undo (ctrl-z) sent randomly on a Dell Laptop

    - by squelart
    For the past couple of weeks, my laptop has had a strange problem where it looks like ctrl-z is pressed, so I usually lose bits of text I just typed. If I press ctrl-shit-z (redo), the text comes back, proving it's really as if ctrl-z was pressed. It's difficult to see a pattern, I can be undo-free for hours, then get a few within minutes, sometimes 2-3 undoes at a time. Very frustrating! Running WinXP+SP3 on Dell Latitude D820, Clamwin antivirus. I've tried another keyboard, no difference. Any clue on what this could be, or how I could trace this problem? 2009-09-25: Tried a few things that were listed or linked to on this page: http://www.selfishman.net/2008/06/24/problem-with-dell-inspiron-1501-keypress-every-second/ but nothing helped. Though it seems to point at a Dell laptop issue. I upgraded the BIOS and other drivers, but still got the problem.

  • Postfix/dovecot remove LDAP user

    - by dove221
    I have to remove or blacklist an LDAP/dovecot user. The authentication is setup from active directory what I cannot manage so I thought there should be a way at least to disable this specific user on the mailserver locally. # Virtual Accoutns - LDAP - MS AD virtual_mailbox_maps = ldap:/etc/postfix/ldap_mailbox_maps.cf virtual_alias_maps = ldap:/etc/postfix/ldap_alias_maps_redirect_true.cf ldap:/etc/postfix/ldap_alias_maps_redirect_false.cf ldap:/etc/postfix/ldap_mailbox _groups.cf virtual_mailbox_domains = domain.com virtual_uid_maps = static:1000 virtual_gid_maps = static:1000 virtual_transport = dovecot dovecot_destination_recipient_limit = 1 Anybody knows how to do it? I followed this guide for disabling 1 user through postfixes access file: http://www.cyberciti.biz/faq/howto-blacklist-reject-sender-email-address/ Unfortunately it doesn't work. It's like the settings stored in LDAP are overruling the access rule. Instead of postfix rejecting the mail it keeps accepting it. Thanks!

  • Ubuntu server hangs on reboot "could not stat resume device file"

    - by matnagel
    Instead of booting into the running system this machine stops and on the terminal I can see a message: could not stat resume device file /dev/sdb5 When I attach a keyboard and press enter the boot continues and the machine comes up like normal. But it's essential that this machine comes up under most circumstancs alone. There never was something like a "resume" on this machine. I tried several times to reboot, but this does not happen on all boots, I can not find a pattern here. There is a software raid running on the box. This is the syslog during boot: http://privatepaste.com/ff0fd0a51c/sdabfjahfgasjkgfu4gfsdzjcgfafasdjfhgasdcjfgauzfgafasgdufzg How can I get rid of this boot failure? We do not need resumes and best would be something that works here and now.

  • How do I get detailed information about what happens during logon

    - by Funky Si
    Due to my IT department leaving I am now responsible for all our IT systems. I now have several problems to get my head around and fix. I run Active Directory on windows server 2003 and use group policy to apply settings etc. Recently we have had some windows 7 clients added to our network, these are having awful problems with our logon scripts and drive mappings. For the most part my XP clients are working without a problem. What I want to know is what is going on during logon, as running the logon scripts after I have logged on often works. Does anyone know of a way to get detailed log information of what is happening before and during logon. Thanks for your help and any suggestions you have for tracking down the source of these problems.

  • What is the specific advantage of a blade server for virtualisation?

    - by ChrisZZ
    We are planning to implement a VDI Solution. We had some discussions about Blade vs Rack. As we are only planning to implement 75-100 Clients, we calculated, that we would need 2 Servers with Dual 8C Processors - and a shared storage server. This calculation is based on a paper by ORACLE, that says, 12 active virtual machines per core. Now, for buying to servers, a blade does not scale financially. But the Blade has some other advantages: a) The interconnectivity between the blades is super-fast. b) IO Virtualisation Are there other advantages, that we should consider, that would make up for price - and are this advantages so important, that we should think about investing in the blade?

  • How to populate the span tags for all text nodes between specific self closing tags.

    - by Rachel
    I want to populate span tags for all text nodes between the self closing tags s1 and s2 having the same id. Eg. For the input: <a> <b>Some <s1 id="1" />text here</b> <c>Some <s2 id="1"/>more text <s1 id="2"/> here<c/> <d>More data</d> <e>Some <s2 id="2" />more data</e> </a> In the above input i want to enclose every text node between <s1 id="1"/> and <s2 id="1" /> with span tags. Also all the text node between <s1 id="2" /> and <s2 id="2" /> Expected Output: <a> <b>Some <span class="spanClass" id="1a">text here</span></b> <c><span class="spanClass" id="1b">Some </span>more text <span class="spanClass" id="2a"> here</span></c> <d><span class="spanClass" id="2b">More data</span></d> <e><span class="spanClass" id="2c">Some </span>more data</e> </a> I am not concened about the pattern of the id tag populated for the span as along it is unique. If the transformation of the input to the output form requires the list of ids of the s1 , s2 tag pairs say 1, 2 etc i can assume that it in place in any form if required. Hope i am clear. How can this be achieved using XSL? EDIT: The input can have any structure and not exactly the same as seen in the sample input. It can have any number of s1, s2 tag pairs but each pair will have a unique id.Adding another sample input and output pattern for more information. Input: <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>This is my title</title> </head> <body> <h1 align="center">This <s1 id="1" />is my <s2 id="1" />heading</h1> <p> Sample content <s1 id="2" />Some text here. Some content here. </p> <p> Here you <s2 id="2" />go. </p> </body> </html> Desired output: <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>This is my title</title> </head> <body> <h1 align="center">This <span id="1">is my </span>heading</h1> <p> Sample content <span id="2">Some text here. Some content here.</span> </p> <p> <span id="2">Here you </span>go. </p> </body> </html>

  • How can I make Windows Media Player ignore global hotkeys in Windows 7?

    - by Schnapple
    I have Windows 7 and a Logitech G15 keyboard. One of the programs with the Logitech G15 allows you to control media players such as Winamp with the playback keys on the keyboard. Problem I'm having is that, even though I have told this program to not control Windows Media Player, every time I use it to pause Winamp, it then hits plays (or unpauses) Windows Media Player. Even more annoying given that Windows Media Player isn't even running as an active GUI program and instead as a background process, so I hear the sound of whatever the last video it was I playing. If I end-task wmplayer.exe it spins right back up but at least now it has no knowledge of a video to play, but this is annoying. How can I either a) Have Windows Media Player in Windows 7 completely unload when I close it, or b) Have Windows Media Player in Windows 7 ignore any sort of global hotkeys?
