• How can I shut down all my Virtual Machines when my UPS kicks in?

  - by Tim

  I have a Dell T610 running ESXi4, an APC Smart UPS 1000VA and a local "console" machine running Vista and the vSphere 4 Essentials pack. A dedicated management network is in place between the T610 and the Vista machine. We have 4 VMs: SBS 2003, Server 2003 running Terminal Services, and two XP Machines. Ideally, when the UPS is forced to use battery power [for a set number minutes], I would like to gracefully shutdown all the VMs, then the ESXi, then the console machine. The latter two are not strictly a priority, but the VMs within ESXi are. Google provided lots of deprecated scripts that used to work on ESXi 3.x or similar, however I am unable to find what they were deprecated by. What do I need to be able to do this? I have Powerchute Express as supplied with the UPS, but would be willing to pay for software if required.

• Problem with SAT collision detection overlap checking code

  - by handyface

  I'm trying to implement a script that detects whether two rotated rectangles collide for my game, using SAT (Separating Axis Theorem). I used the method explained in the following article for my implementation in Google Dart. 2D Rotated Rectangle Collision I tried to implement this code into my game. Basically from what I understood was that I have two rectangles, these two rectangles can produce four axis (two per rectangle) by subtracting adjacent corner coordinates. Then all the corners from both rectangles need to be projected onto each axis, then multiplying the coordinates of the projection by the axis coordinates (point.x*axis.x+point.y*axis.y) to make a scalar value and checking whether the range of both the rectangle's projections overlap. When all the axis have overlapping projections, there's a collision. First of all, I'm wondering whether my comprehension about this algorithm is correct. If so I'd like to get some pointers in where my implementation (written in Dart, which is very readable for people comfortable with C-syntax) goes wrong. Thanks! EDIT: The question has been solved. For those interested in the working implementation: Click here

• Commit charge peak higher than system limit

  - by Grubsnik

  We are seeing some very strange behaviour on our servers and google didn't turn up anything usefull, so I'm tossing it out here. A standard server is configured with 4GB Ram, 2 4GB pagefiles and running windows server 2003. The servers are running 50-120 vb6/.net applications which normally consume no more than 100mb of memory, but will occasionally run up to 300 mb. The issue with a single process spending way too much memory is being traced down somewhere else, but the thing that is baffling us is that the reported peak charge is vastly higher than what we have available. As the image above shows, we are getting reported peaks that are way higher than what the system is actually capable of delivering. This number has been seen as high as 29GB, which makes no sense at all for a system with a limit of 12GB. Does anyone have an idea what is going on?

• Practical way to set up an email inbox for testing?

  - by Ben Collins

  I need to test a high-volume email application. Up to now, I've just been using gmail ad-hoc aliases ([email protected]) to receive emails and see that the content is right. However, I now need to verify a recipient list, which means I need to get every single email that goes out on a particular test run. The problem with Google isn't clear, but there's some throttling somewhere (perhaps from SendGrid, who is my delivery provider), and only a very small number of those emails ever make it to my acount. So: what's a practical way to get where I want to be? Is there a way to get gmail to just accept everything? Is there a web app / service somewhere that will let me throw up a fake email address that can receive for a large number of recipients? Is there something else?

• Generate metadata of all files in a dir?

  - by nmuntz

  We are working on a project that is quite big, and its stored in an SVN repository under different folders with many files all over the place. Quite often, it is hard to locate the document that has a certain keyword or phrase. Does anyone know of any program that will generate and index the metadata of all the files that are in these documentation folders? (most filetypes are: xls, doc, ppt). Windows Search and Google Desktop could be an option but that would generally index the whole hard drive, emails, etc and thats probably much more than what we need and would not be suited for something more folder specific. Example of what im looking for: a program or webpage where i enter "John Doe" and it will show me all files in MyProjectFolder/ that contain the keyword "John Doe". This of course will already be indexed somewhere so searches should be almost instantaneous. Is there such a tool or i am asking too much? Thanks in advance!

• Tool/Program/Script/Formula for deciphering Active Directory Connection Strings for 3rd party user i

  - by I.T. Support

  We're using WSFTP, which has an Active Directory Integration module. To populate the user accounts you need to provide a connection string akin to: OU=Users,DC=domain,DC=com CN=Domain Users,OU=Users,DC=domain,DC=com Questions: Is there a Tool/Program/Script/Formula that allows me to decipher how these strings might look based on what I can see in Active Directory Users & Computers? Is there a proper/accepted name for these types of connection strings? I don't even know what to Google to get more information about how to format one properly How would I troubleshoot the connection string if I think it looks correctly formatted, but it isn't working? Thanks!

• Ubuntu 10.04 User Interface errors

  - by user306668

  Hi Guys Using Ubuntu 10.04 Beta on a Sony Vaio laptop (slightly old PCG-4n7M). It was working wonderfully until this morning. After updating and upgrading the login screen images gave broken image icons, then on logging in UI was replaced with just the cmd shell. All menus are gone. I have tried to reconfigure xserver-xorg and that doesn't work. Reinstalling doesn't either. I have tried a number of other attempts. What is weird is that I can launch graphical applications from the cmd line. such as firefox or google-chrome. and they work but the UI is simplified or broken (no resizing, closing, minimizing). I am a bit lost on how to fix this error. If anyone has any suggestions, please let me know

• URL is generating a /#!/splash-page

  - by user32642

  My site for some reason is generating a shebang - /#!/splash-page on the URL. For example when I type www.modernvintage1005.com, the browser returns www.modernvintage1005.com/#!/splash-page and every subsequent page is /#!/about, /#!/contact, and so forth. There's absolutely nothing on the Google about this. There is a lot of rewrite help to eliminate .index.php from the home page, but that's it. How do I rewrite it to just say domain.com and domain.com/about.html, etc.? Here is my .htaccess file if you need to see it. # Rewrite Rule <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> # compress text, html, javascript, css, xml: <IfModule mod_deflate.c> AddOutputFilterByType DEFLATE text/plain AddOutputFilterByType DEFLATE text/html AddOutputFilterByType DEFLATE text/xml AddOutputFilterByType DEFLATE text/css AddOutputFilterByType DEFLATE application/xml AddOutputFilterByType DEFLATE application/xhtml+xml AddOutputFilterByType DEFLATE application/rss+xml AddOutputFilterByType DEFLATE application/javascript AddOutputFilterByType DEFLATE application/x-javascript AddType x-font/otf .otf AddType x-font/ttf .ttf AddType x-font/eot .eot AddType x-font/woff .woff AddType image/x-icon .ico AddType image/png .png </IfModule> ## EXPIRES CACHING ## <IfModule mod_expires.c> ExpiresActive On ExpiresByType image/jpg "access 1 year" ExpiresByType image/jpeg "access 1 year" ExpiresByType image/gif "access 1 year" ExpiresByType image/png "access 1 year" ExpiresByType text/css "access 1 month" ExpiresByType application/pdf "access 1 month" ExpiresByType text/x-javascript "access 1 month" ExpiresByType application/x-shockwave-flash "access 1 month" ExpiresByType image/x-icon "access 1 year" ExpiresDefault "access 2 days" </IfModule> ## EXPIRES CACHING ##

• How to remove a package I compiled and installed manually?

  - by macek

  I recently compiled and installed Git on a new install of Mac OS 10.6 but it didn't install the documentation. I now realize I should've used the precompiled package offered here: http://code.google.com/p/git-osx-installer/downloads/list How do I remove all the files that I added to my system using make install with the Git source code? Edit: I've had similar problems in the past with other packages, too. For example, ./configure with the incorrect --prefix= or something. What's the general practice for removing unix packages?

• Posting videos to a website... with a dynamically updating interface

  - by Johnny W

  I'm currently putting together a website for my Luddite friend. He needs a blog, photos and videos... all easily updateable by him. WordPress and Blogger both have brilliant functionality to allow you to host your own blog on your own domain, but what about photos and videos? Does YouTube or Google videos or Vimeo or MSN Video or anyone offer the ability to easily insert a video navigation interface onto your own site? (Something similar to YouTube's "Channel" pages, except on your own domain?) Same goes for photos. I'm pretty sure FlickR doesn't allow you to easily upload and manage photos for viewing on your own domain. Does anyone else? My friend doesn't want to be editing any HTML and I don't want to be creating a complicated system to handle tons of different videos. There must a user-friendly solution in this day and age? Thanks for any help!

• Has ec2 made self-hosting possible for 'amateur' sysadmins possible?

  - by Blankman

  I'm a developer, and it seems ec2 has made it possible for a amateur sysadmin like me to setup and maintain a fairly large set of servers. Now I don't mean to undermine real sys admins, as I know the value of them but what I am trying to get at is that someone like me can setup and maintain a cluster of servers (front end web servers, with some db servers) using tools like ec2 and capistrano with the help of google. Now this isn't something I would do as a long term thing, but as a startup, one-man operation, I think I can pull this off until business takes off and I can hire this important role out. With ec2, I get my firewall, so I basically open up port 80 on my public facing server, which will run haproxy and route requests to my cluster of servers. Ofcourse I am simplifying the setup, but just want a feel for what you guys think about my perception. My application is a web application, that will be runing Ruby on rails (passenger) and talking to mysql or postgresql.

• Is there a USB ethernet (wired) adapter that is really compatible with Windows 7 64-bit?

  - by nbolton

  I've checked the Windows 7 compatibility site, and it lists a fair few USB ethernet (wired, not wireless) adapters that should work with Windows 7 64-bit. However, whenever I Google for the model number and Windows 7 64-bit, there's many forum posts claiming that the devices actually don't work with 64-bit (but do work with 32-bit). I've actually also found this with the LUPO USB ethernet adapter; works with 32-bit win7, but not 64-bit (no drivers available). So is there anyone out there who is 100% certain, and have actually used successfully, a 64-bit win7 capable USB ethernet adapter?

• What is the simplest way to render video into memory (for drawing to a texture) in .NET?

  - by sebf

  In my project I would like to be able to play back video on surfaces in the world. I intend to do this by having the video frames rendered to a block of memory, then use this to update a texture each frame. Everything is in place - except for the part that actually gets the video. I have looked on Google and found that the video library world is very expansive (and geared towards video processing), and am having trouble finding a suitable one. FFMpeg is very comprehensive, but is an entire suite and would take a good amount of work to integrate. So far the most promising library I've found is the one based on the VLC player libraries - by virtue of it using the same resources as VLC Player it is known to be very capable; it also renders to blocks of memory, but the API (at least of the one on Codeplex) is more of a port of the C++ API rather than a managed wrapper. The 'solution' can be any wrapper/API/library, but with characteristics that make it suitable for use in a rendering engine, namely: Renders the video frame data to memory, so it can be picked up and passed to a texture on the GPU easily. Super simple - all that is needed is a way to load, jump and render a frame programatically - ideally it would use the systems codecs and not require an assortment of plugins. Permissive license (LGPL or more free-er) .NET bindings at least; all the better if it is natively managed Can anyone suggest a lightweight, (.NET) library, that can take a video file, and spit out some frames into a byte[]?

• How to Use Vim-Style Keyboard Shortcuts for OS X Tab Navigation

  - by The Geek

  After switching to OS X when I got a new MacBook Air, one of the first things I needed to duplicate was my extremely customized AutoHotkey setup — the most important of which is using the J and K keys to navigate throughout tabbed windows easily. Yeah, I’m a Vim user. I’ve never been a fan of having to use CTRL + TAB to switch from one tab to the next — to start with, you have to move your hands from the home row, and it’s awkward, and why should I have to do that just because somebody decided that keyboard shortcut before tabs became popular? If you think about it, if tabbed browsers were popular back when keyboard shortcuts were being invented, they would have definitely reserved some of the good shortcuts for switching tabs. On Windows, I’ve always used an AutoHotkey script to make things the way I wanted it:  ALT + J and ALT + K for selecting previous and next tabs. Once you get used to it, it’s extremely awesome, and so much faster than using CTRL + TAB. Of course, I also hacked CTRL + T and CTRL + W into ALT + T and ALT + W so I could open new tabs and close them without moving my hands from the home row. Over on OS X, it turns out that it’s incredibly simple and easy to use CMD + J and CMD + K for next/previous tab navigation, and it works in most applications that support tabs, like Terminal, Safari, or Google Chrome.

• How to prevent these executables from starting up?

  - by TomWij

  After removing the following executables from starting up, in the near future they reappear again: DDMService.exe: Re-enabled when visiting a DivX video online. DivXUpdate.exe: Re-enabled when visiting a DivX video online. GoogleUpdate.exe: Re-enabled task, I think by Google Chrome? I see no auto-update option. iPodService.exe: Re-enables after starting iTunes. iTunesHelper.exe: Re-enables after starting iTunes, useless on SSDs. Reader_sl.exe: Re-enables when updating Adobe Reader, useless on SSDs. It bores me that these processes keep popping back up, while my software functions well without them. I'm smart enough to update the software weekly through FileHippo so I don't need automatic updates. What can I do to never see these processes again? Even after reinstallation of those applications... A general solution is also welcome! :-)

Whenever I google it only come up with apt-get uninstall and so forth. Thank you

• Vmware server: Browser does not load user interface

  - by matnagel

  I have the latest vmware server isntalled on ubuntu 8.04 lts 64 bit. I access the user interface over this url, which matches my ip and port settings: https://10.1.1.99:11222/ui Sometimes it works in fierofox 3.6, but sometimes not. Same in Google Chrome. When it does not work, what happens is that the cert is checked, the browser is loading something, but the result is a white page. Sometimes the favicon of vmware (blue with 3 squares) appears, but only the white page. And sometimes it works. I reload many times, most of the time the whit epage appears again. On some days I succeed. But on many days not. I can give more info if someone tells me what is needed. Please help, we need this badly.

• automated printouts from a wireless printer

  - by Piotr

  I have a wireless printer which is always on, and an always on fanless linux server. Looking at the mprinter project on Kickstarter I started to wonder if there is an app somewhere in the internet already that will allow to prepare an automated daily printout based on some settings. things to be printed could include - weather forecast for my locations, todo`s scheduled for that day, a "quote of a day" or "word of the day", stats from google analytics for my site, and many more ... I would set a printout at 6:15 every work day so its on my printer when I am already up, having a coffee. anyone knows something that can be used for such purpose? While I know this can be done by combining the power of TeX, cron and a script language to manage the dynamic part of the PDF I believe this is a use case someone has already addressed.

• Remove Trailing Slash from WordPress URL (The site also don't have www)

  - by mrintech

  I need help as I am confused a lot with .htaccess Some months back, I removed WWW from the URL of my domain name using following .htaccess lines: RewriteCond %{HTTP_HOST} !^example.com$ [NC] RewriteRule ^(.*)$ http://example.com/$1 [L,R=301] Now, I also want to remove the trailing slash from the URL, as because I am using WordPress and a page/post will open, no matter if there's a trailing slash or NOT! I request you to please provide me the .htaccess code, so that I can REMOVE the trailing slash. Kindly remember, I don't want WWW also and I have already set .htaccess rule for the removal of WWW Note: 3 Years back when I started the blog, I set the Permalinks Structure without trailing slash. Now, suddenly Google Webmasters Tools is showing warnings. Also, the URL for rel="canonical" is WITHOUT trailing slash If you require any more details, I will be happy to provide

• Dedicated Servers: Is one better then two for LAMP pseudo HA setup? [closed]

  - by bikedorkseattle

  Possible Duplicate: How to find web hosting that meets my requirements? I know there are zillions of commentary about hosting out there, but I haven't read much about this. Our current well known host is having too many problems, the hardware we are on it subpar, and I'm ready to leave. A day of downtime can cost as much as our monthly hosting bill. A month of bad performance is just killing us right now, user and google wise. I'm wondering about running two dedicated boxes for LAMP, one running as the primary Nginx/Apache (proxy pass), and the other as the MySQL box. Running a single box scares the bejesus out of me because who knows how long it will take anyone to fix a raid card or whatever. The idea is to set this up using some sort of failover system using pacemaker and heartbeat. If one server goes down the other can take over for the other running both web and db. There are some good articles over at Linode about this. I have a few DBs that are 1GB+ and would like to load them into memory. Because of this, I'm shying away from a Linode HA setup because for the price I could do it with two dedicated like I described. Am I mad or an idiot? What are people out there doing for pseodu high availability good performance setups under $400/month? I'm a webmaster; I do a lot of things none of it that well :)

• Is my project a web site or a mobile app?

  - by Evik James

  I am a web developer. I have been developing web sites professionally for 15+ years using ColdFusion, SQL Server, and jQuery. I am doing a project for a client that uses the above technologies. The site has a mobile facet too. For that, I am using jQuery Mobile. The site enables retail store personnel to gather a store customer's preferences using any smart phone or tablet. The store personnel just needs to access a special link via a QR code and a login. Anyone can easily access the site from a PC's browser, too. Some sources suggest that mobile apps must be downloaded and installed using a third party, such as from Google, Amazon, or Apple. Others sources suggest that any information designed for use on mobile device is a mobile app. Regarding the site that is specifically designed for use by mobile devices that extensively uses jQuery Mobile, is this a "web site" or a "mobile app"? What is the "proper" description for this type of site? My customer insists that it is one and not the other. I insist that it is the other and not the one. Can you help me clarify this?

• How do I disable microphone volume auto-adjusting?

  - by balpha

  My coworkers started yelling at me today because apparently I started screaming in their ears during a Google hangout. And sure enough, when I go to the Microphone settings dialog, I can see the level being auto-adjusted constantly; sometimes way too high. I don't think this has happened previously; at least nobody ever complained. Can I find out who is doing that auto-adjusting, and more importantly, can I turn it off? I couldn't find any related setting in the recording device settings. I'm using Windows 7 64bit, and (I'm mentioning this because the theory has come up that it may be related) I don't have Skype running.

• Windows 7 starter will not shutdown or logoff

  Im having some problems with a friends netbook (a dell mini 10). It will not shutdown or logoff via the usual route. Whenever the shutdown/logoff button is clicked, it will briefly freeze (maybe for only a second) and then do nothing. Ive tried shutting down manually via the command line using shutdown /p but all to no avail, it just defaults back to flashing cursor in the command prompt. There doesnt seem to be any mention of a similar problem on google so i was wondering if anyone else had any ideas. Thanks oh and its runnning windows 7 starter.

• How can I see the metadata of an ISO file?

  - by netvope

  I have been searching for the list of metadata field of an ISO file on Google but couldn't find anything. That made me think that there isn't any metadata in an ISO file, just the files content and their properties. However, today I find in ImgBurn that there is a field called Imp ID, which typically contains the software used to create the ISO file. I'm not sure if it is specific to the UDF and/or CDFS filesystem. What are the other possible metadata fields in an ISO file? What software may I use to see them?
