• Funny/clever/creative HTTP error pages

  - by David

  I'm sure many of us have seen or heard of amusing ways to express the standard HTTP errors, like "404 Lost in Cyberspace" instead of "404 File Not Found". What are some of the funniest/cleverest/most creative error pages or error messages you've seen, or can think of? (Somewhat similar to this question on StackOverflow) I know this isn't a specific question with a single answer but it is relevant to site admins who want to keep their visitors happy (or terrified, if you prefer ;-) I'll certainly be looking for inspiration for my own website's error pages.

• Recommended Server RAM for SQL Full Text Search (FTS)

  - by David

  I gather SQL Server 2008 Express requires a minimum of 512MB RAM to be installed to run on Windows Server 2003, however will this be sufficient to also run Full Text Search on about 50,000 records? I don't want to pay too much and I have seen a 512MB RAM VPS option that interests me. Thanks

• How do I deliver mail for wildcard addresses to a particular user/alias/program?

  - by David M

  I need to configure sendmail so that mail delivered for wildcard addresses is accepted for delivery and then delivered to a user, alias, or directly to a script. I can rewrite the envelope/headers any number of ways, but I don't know how to accept the wildcard address when it's provided in RCPT TO: Everything I've tried so far winds up with a 550 user unknown error. So here's a specific example: I want to be able to handle any address that consists of a series of digits followed by a dot followed by a word, then pipe that to a script. If the headers get rewritten, that's OK, but I need the envelope to contain the actual Delivered-To address. Here's the sort of SMTP session I need: 220 blah.foo.com ESMTP server ready; Thu, 22 Apr 2010 20:41:08 -0700 (PDT) HELO blort.foo.com 250 blah.foo.com Hello blort.foo.com [10.1.2.3], pleased to meet you MAIL FROM: <[email protected]> 250 2.1.0 <[email protected]>... Sender ok RCPT TO: <[email protected]> 250 2.1.5 <[email protected]>... Recipient ok I tried some stuff with regex maps, but I never got past 550 user unknown.

• Advantages of a 130W vs 90W ac adapter?

  - by David

  I purchased a Lenovo T420S laptop with a 90W/20V AC adapter P/N 42t4426 through my IT department. Subsequently, I ordered a replacement adapter and received a 135W/20V AC adapter P/N 45N0054. The 135W version is about twice as big and heavy as the 90W version. Is there an advantage to the 135W version like faster battery recharging? Are there any negative effects (other than weight), like reduced battery life?

• How do I get Windows 7 wallpaper to display the company logo properly?

  - by David Silva Smith

  Windows 7 is not displaying our company background properly. Curves show pixelation and straight lines are jagged. I'm working with a scalable vector graphics (SVG) image that I've exported to the same resolution (pixel dimensions, to be technical) as the desktop, which is 1440x900. I have tried exporting the image as a .png, .jpg, and .bmp. All of these look correct in an image viewing program, such as Windows Photo Viewer and Paint, but when I set the Windows background to these images, curves show pixelation and straight lines are jagged. Reading online, it seems that behind the scenes, Windows is converting the image to a .jpg with low quality compression, which is causing the issue. I've tried setting the image as a background through Internet Explorer, saving it as a .jpg, and putting the file in the Windows photo directory as suggested in some online forums, but none of those solutions have fixed my issue.

• How do I access an Ubuntu VirtualBox guest at a static IP from an OS X host?

  - by David Siegel

  How does one configure an Ubuntu guest to use a static IP that's visible to an OS X host, and ensure that the static IP is independent of the host's network configuration? I previously used bridged networking for my guest, but I'm constantly moving my host between networks so the guest IP is always different. First, I tried setting the guest network configuration to NAT and forwarding host port 1022 to guest port 22, so I could at least ssh to a fixed address (localhost:1022): $ VBoxManage setextradata "Ubuntu Server" "VBoxInternal/Devices/e1000/0/LUN#0/Config/SSH/Protocol" "TCP" $ VBoxManage setextradata "Ubuntu Server" "VBoxInternal/Devices/e1000/0/LUN#0/Config/SSH/GuestPort" 22 $ VBoxManage setextradata "Ubuntu Server" "VBoxInternal/Devices/e1000/0/LUN#0/Config/SSH/HostPort" 1022 Then, $ ssh localhost -p 1022 ssh: connect to host localhost port 1022: Connection refused But this didn't work (guest has no network access with NAT and OS X refused the connection, as you can see). I'd love a general solution that would let me communicate with my guest at a fixed IP.

• Modifying %HOME% on Emacs 24.3 on Windows causes .emacs to not be found

  - by David

  In order for magit to read my git settings on Emacs 24.3.1 for Windows, I added the following configuration from a stack overflow post: (when (string-equal system-type "windows-nt") (setenv "HOME" (concat (getenv "HOMEDRIVE") (getenv "HOMEPATH"))) Interestingly, after this is added to my .emacs, Emacs thinks .emacs doesn't exist anymore. If I do M-x cd to ~ and then do M-x pwd it says ~ is located at C:\Users\Me\AppData\Roaming. It appears that emacs is reading the .emacs settings file because it loads my custom theme. However, if I try to find ~/.emacs Emacs doesn't see it. The file has all permissions on the file system for any user.

  - by david.joyce13

  I'm stumped. As directed, I printed the Font Awesome Cheatsheet to PDF. When I open it with Acrobat Reader, it looks fine. However, when I try to open it with Illustrator, I get this warning: The font MuseoSlab-500 is missing. Affected text will be displayed using a substitute font. The font OTS-derived-font is missing. Affected text will be displayed using a substitute font. The font ProximaNova-Regular is missing. Affected text will be displayed using a substitute font.

• How to get Windows Server 2008 VM to use multiple cores

  - by David Fraser

  I have a Windows Server 2008 machine running in VirtualBox. On initial installation, only one processor was made available, but now I want to run it as a multiprocessor machine. I have made all four cores available in the VirtualBox settings (as well as enabling VT-x/AMD-V and Nested Paging), but Task Manager still only shows one CPU. However, the four CPU cores are visible in Device Manager under Processors. In the event log on startup, I can see the following relevant events: EventLog.6009 Microsoft (R) Windows (R) 6.00.6002 Service Pack 2 Multiprocessor Free Kernel-Processor-Power.4 Processor 0 exposes the following: 1 idle state(s), 0 performance state(s), 0 throttle state(s) Kernel-Processor-Power.4 Processor 255 exposes the following: 0 idle state(s), 0 performance state(s), 0 throttle state(s) Kernel-Processor-Power.4 Processor 255 exposes the following: 0 idle state(s), 0 performance state(s), 0 throttle state(s) Kernel-Processor-Power.4 Processor 255 exposes the following: 0 idle state(s), 0 performance state(s), 0 throttle state(s) How can I make this system actually boot up as a multiprocessor machine?

• Domain Squatter Blacklist

  - by David Chang

  Is there a list of common ip addresses used by domain squatters (the ip addresses of the sites they resolve the domains to)? I have a list of domains and I need to remove most squatted/parked domains from the list, I can do that in a perl script (that currently removes dead domains) but I need the IP addresses the squatted domains resolve to so I can remove them as well. I know there are spam/phishing/malware blacklists available, does anyone know of a squatter blacklist? I can't find one using Google. EDIT: I am trying to remove dead domains from a list, I can already remove domains that don't resolve but I need to remove squatted domains as well so I need a list of ip addresses squatted domains resolve to so I can remove them.

• Merge Visio files

  - by David Stratton

  I know I can do this manually by using copy/paste but I'm looking for a simpler way. Does anyone know of a quick and easy way to merge Visio documents? I have several Visio vsd files, all of which are the same internal document type (Flowchart - US Units). Each of these has between 1 and 15 pages. I'd like to combine them all into one Visio file. I'm using Visio for Enterprise Architects (11.4301.8221) so if there's a procedure for doing it in that version, that's what I'm looking for, but a 3rd party tool or a macro would work as well.

• Simulate analogue steering wheel input from third party software like xPadder

  - by David Jensen

  So. I currently have a steering wheel connected to my htpc. Since it wont work / get recognized by all games i play. I use xpadder to play for example Grid 3. As far as i have understood, it simply presses the associated arrow key when i turn the wheel. What i would like, is a software to simulate more and more frequent key presses of the arrow keys the more i turn the wheel. Example: Tilting a little - 100 presses / second Tilting more - 200 presses / second Tilting max - Hold down key Because what i currently do with the wheel is constantly shaking it a bit right, when i just want to turn a little bit right and so on.

• Opening tabs in Google Chrome crashes my system

  - by David Golding

  When I open tabs to sites such as BBC iPlayer I have about a 4/5 chance that it will crash my entire system. The system can remain unresponsive for up to 30 mins or as little as 2. This has only happened recently and is becoming very annoying as the rest of my system can be running perfectly fine then I open a tab and it hangs. It isn't always flash media webpages so I have ruled that out and I have check my addons opened them in incognito mode, done all the usual error checking.

• DNS pointing to different IPs from different parts of the world

  - by David

  I have a domain name that for some reason is pointing to different servers depending on where you are located in the world. What is odd is that I have another domain that has the same DNS servers, which points to the same server regardless of your location (which is the way it's mean't to work). Any ideas why the first domain is pointing to different IP addresses for different people?

• How can I create a windows shutdown script from powershell/command-line?

  - by David Rubin

  I've read the TechNet pages that describe using computer/user startup/shutdown scripts, and that's great, but I'd like to create those scripts via the command-line (and not have to click around in gpedit.msc). It looks like scripts.ini and psscripts.ini in %SYSTEMROOT%\System32\GroupPolicy\Machine\Scripts specifies the scripts to run, but those don't exist until running gpedit.msc for the first time. Is it safe to create and edit those directly? Or do I need to muck around with Set-GPO or something similar? Thanks!

• Windows Server 2008: How to tell if a user is a 'local' use or a 'domain' user

  - by David

  I'm a developer, not a server admin, so please bear with me! I've been tasked with checking the installation of some software on a Windows Server 2008 R2 machine in the cloud, within two scenarios: There is no domain, the software will use local users and groups for authentication There is a domain, the software will use domain users and groups for authentication I've done part 1, but I'm puzzled about part 2. I've just installed the Active Directory Domain Services role on the server, so now I have a domain of one computer. When I look in Active Directory Users and Computers, I see all my original local users and groups. Have they now been 'promoted' to domain users? Or do I not have any domain users yet? Is there a way I can tell the difference between domain users and local users now? Thanks

• Configuring my Linux firewall for Tomcat

  - by David Pinn

  I'm following some instructions for Installing Tomcat. They require me to add the following line to my iptables file: -A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 8080 --syn -j ACCEPT Having carefully read the man page for iptables, I have learned what the parameters do, except for the first one. What does -A RH-Lokkit-0-50-INPUT do, and can you confirm that it is sensible in this case?

• How do I fix a corrupted copy of .Net Framework on Windows 7?

  - by David

  I receive the following error when trying to run applications that require .net Framework 3.5: "Could not load file or assembly 'System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The module was expected to contain an assembly manifest." I've tried numerous fixes, such as reinstalling through ad/remove software, copying the .net folder over from a clean windows 7 install, and running the .net cleanup tool. Just wondering if anyone has run into this issue before, or has an idea on how to fix it.

• Setting Redmine path

  - by David Parunakian

  Hello, How can I set the path on which Redmine should be run, e.g. example.com:3000/redmine instead of example.com:3000? There is an appropriately named option in the settings panel, but it serves a different purpose, according to the documentation and experimental observations (it is used to write URL in emails sent to users). A wider picture: I need this in order to properly serve Redmine on port 80 over Apache's mod_proxy (i.e. at example.com/redmine). The problem is that when running it on /, the home page fails to load the necessary resources (such as JavaScript and CSS files). Any workarounds?

• Is the APC BR700G UPS (or similar) compatible with Active PFC power supplies?

  - by David Zaslavsky

  I'm looking at getting a UPS for my home computer. So far the APC BR700G looks very promising, except for one thing: one of the reviews on Newegg says that this UPS does not work with a power supply with Active PFC. Pros: Unit looks great, built well, very heavy, was excited to use it. Cons: Didn't research enough - many newer power supplies like my corsair 750w (and yes dells and other mainstreamers sell them too) that I bought last year have a feature called active pfc (power factor corrected). The signal for this backup battery doesn't fully support that feature and can cause issues. You can find an article on APCs site if you search their user forums for PFC. And the power supply in my computer is, in fact, an Active PFC PSU. I've already found one answer on this site claiming that it's not an issue, that "most quality supplies these days have PFC and work just fine with a UPS." That disagrees with the review on Newegg. Can someone explain this discrepancy? Also, what is it exactly about a UPS that makes it incompatible with an Active PFC PSU? (if anything) Is there some way to tell based on the technical specifications, or do I just have to hunt for reviews online to avoid wasting my money? While any input would be appreciated, I would prefer to get an answer from someone with actual experience with similar UPS's and Active PFC power supplies, who can tell me whether it works or not.

• Plesk hosting on MediaTemple DV

  - by David

  Hi there, We have a MediaTemple dedicated virtual running Plesk. The problem we're having is that changing the permissions of files on the server to be writable by server owner (apache) is conflicting with the ability to upload and overwrite files via the FTP user. Here's an example, I upload a file from user "serverftp" and they own the new file in the httpdocs folder. I then change the permission of an image upload folder to the apache user to that I can upload images via a PHP script. Uploading or changing that folder with the serverftp user is then locked out. Speaking to tech support didn't get very far because there are some strange group permissions going on and it would involve me adding every single domain FTP user to the pcantl group or something similar. I'm wondering how I can easily change things so that I don't have this problem anymore.
