• How to step down voltage from 208V to 110V

  - by Eric Dennis

  I have some racks that will be fed by 208V/20A circuits. These circuits will be conditioned and battery-backed by the facility in which these racks will live. 99% of the devices in the rack will be able to support 208V input, so I plan to use these PDUs. However, there may be one or two odd devices that will need 110V input. I know that I can use a step-down transformer to provide 110V for these devices, but that seems like overkill for such a small number of devices, plus I don't want to pay extra for the UPS functionality since my power will already be battery-backed. Any suggestions for something I can use for these one-off 110V devices?

• Can I use the voice & SMS features of my GSM SIM through my laptop?

  - by i..

  My laptop (a Lenovo T410s) has an internal GSM modem (device manager calls it a Qualcomm Gobi 2000 HS-USB Modem 9205) that I'm currently using a regular (voice, data, text, etc) 3G SIM in. The data functionality works great through the Lenovo software & Windows 7 but I was wondering if I can use the other features (specifically voice & SMS) through Windows. Is it posisble to use the non-data features of my 3G SIM through my Qualcomm GSM modem? If so, what software is available to this end? If not, where is the restriction? (e.g. hardware, OS, driver, software) Thanks!

• Is email forwarding to the sender's address usually blocked in Mail servers / MTA ?

  - by codecowboy

  I've noticed that email forwarding to an address seems not to work if I send an email from the address to which I am forwarding email. This happens for GMail and Fasthosts mail servers. e.g I send an email to [email protected] from [email protected] , [email protected] is set to forward to [email protected] and the email never arrives. I realise this seems logical but it is a potential cause of confusion when testing email functionality in a web application (for me, anyway ;-). I would just like to know if this is standard for all MTA software so I can avoid confusing myself.

• Mouse wheel does not work in Excel 2007

  - by Chris Noe

  I am running Office 2007 on Windows XP-SP3. My mouse wheel works fine in other applications, meaning that it scrolls information up and down when the mouse is positioned over a given panel. It's even working fine in the other Office 2007 apps, so this is not a hardware or driver problem. It doesn't help to click on a cell to give the worksheet focus. I've tried various Advanced options that people recommend, to no avail: Allow editing directly in cell Zoom on roll with IntelliMouse What the heck, has Microsoft disabled this most useful functionality?

• Podcast aggregation - please recommend for Windows 7

  - by bazza-formez

  Hi, I need a good podcast aggregator. I was using Juice 2.2, but that will not work on my new pc which is running Windows 7 (64 bit). Could anyone recommend one please ? I need the following functionality : 1- Subscribe to podcasts (mp3's from radio shows) using rss 2- Have OPML support so I can load up my old subscriptions easily 3- That runs quietly in the backgrond and looks after itself 4- That deletes old episodes automatically after a set time 5- Isn't just designed for an IPOD (I use a simple generic mp3 player to listen). Any ideas? Thanks! Bazza

• "Turn Off The Lights" on any website?

  - by gojira

  On Youtube, there is this nice button (easy to overlook - top left of the video) which lets one "turn off the lights": the site background changes from white to black, the text color changes from black to grey. There is an unrelated plug-in for Firefox called "Turned Off The Lights", which has a very similar functionality. This makes websites so much easier to read. However, both technologies only work on YouTube. Is there anything to achive the same effect for all websites? Preferably with Firefox? I.e.: I want to have very dark background and light text color on all websites viewed with Firefox, how can I do that?

• Are there other application layer firewalls like Microfot TMG (ISA) that do advanced http rules?

  - by Bret Fisher

  Since the old days ISA and now TMG have had several great features that I often want to deploy to my customers because of the enhanced functionality and security, but often the cost of an additinal server HW, Windows Server, and TMG license is too much to justify when compaired to a $300-500 appliance. Are there other gateway firewalls that can perform one or more of these application layer features: pre-auth incoming http traffic against AD/LDAP before sending packets to internal server (forms auth or basic creds popup)? read host headers of incoming http traffic (even on https) to a single public IP and route packets to different internal servers based on that host header?

• Debian/Ubuntu apt or pbuilder without root privileges?

  - by Tem Pora

  I want to use apt or pbuilder to build a package in user's home directory. The home directory has enough space to hold the package's source, its dependencies and binary output. But the apt and pbuilder documents say that you have to be a root user (sudo) to use it. It's frustrating, as the only way now I have at my disposal is to build the package from source or use the dumba$$ (sorry for bad language) dpkg and in both cases figure out every dependency manually, create the dir layout manually and install the built things manually. Now if I can do all these things manually, why the tool writers (apt) think that doing so using their tool (apt) is somehow more special/dangerous? I don't want to use root privileges JUST to build and test a user-land package. If I am NOT allowed to do anything outside my home dir then why NOT the apt or pbuilder type commands be allowed to "build" something in my home dir without root privileges? I just want to use their functionality. It seems there is nothing like Gentoo Prefix from Debian

• Emacs quail: Less verbose completions?

  - by kdb

  Emacs's quail functionality with (set-input-method "TeX") is great for typesetting mathematical notes in plain text. It even has completions, but, well... After \su<TAB> I get Possible completion and corresponding characters are: \su: - \sub: - \subs: - \subse: - \subset:(1/1) 1.? \suc: - \succ:(1/1) 1.? \succa: - \succap: - \succc: - \succcu: - \succe: - \succeq:(1/1) 1.? \succn: - \succna: - \succns: - \succs: - \succsi: - \sum:(1/1) 1.? \sup: - \sups: - \supse: - \supset:(1/1) 1.? \sur: - \surd:(1/1) 1.v Is there some possibility to make the completion output less verbose, showing only the full completions rather than the full paths?

• Thunderbird replacement with PGP support

  - by Robert

  Is there any good Thunderbird replacement with full PGP support ? To be more exact replacement for (Thb +Enigmail this is the tandem Im using now) Best way would be if PGP would be built in into application. Commercial software is also fine :) excluding M$ software. What I need: - PGP support - application much more stable than Thunderbird, - support for Gmail out of the box including support for labels, - better search functionality (search in THB is far away from perfection), - cross platform (I should be able to run it on windows and Linux). So do you guys have an experience with other mail clients which have PGP support ?

• What is an Acer Converter Port?

  - by ShadowHero

  What is this port "Acer Converter Port"? Very little information can be found on the internet. It's basically the same as miniDP? Can I connect a monitor like Dell U2713H on this one? EDIT From this page: http://acer.custhelp.com/app/answers/detail/a_id/30837/~/frequently-asked-questions-on-the-aspire-r7-series 9. Can I connect a DisplayPort monitor to the Acer Converter Port? The Acer Converter Port uses the same physical port as a Mini DisplayPort, but is designed to connect to an Acer proprietary cable. If you connect a DisplayPort monitor, Acer cannot guarantee the functionality of the monitor. No damage should occur to either monitor or notebook by connecting a Mini DisplayPort cable. So, the question is, can someone confirm this will work for sure?

• Do I need a web service for watershed.ustream.tv?

  - by Corey

  I am looking to use the watershed.ustream.tv service for a one-time event. Do I really need my own web service? In the control panel it says “WARNING: the test web service will always approve all requests so do NOT use it in a production environment!”. I'm not looking for any advanced features, I'm not even using the chat functionality. All I want to do is broadcast a funeral service without any advertising. I've looked for support on the watershed site, but I can't find any. Any help or advise would be appreciated.

• Software that can identify and remove foreground objects from image

  - by Antonio2011a

  I am interested in removing extraneous objects from an image. More specifically the situation is that there is a series of images of a particular background. In each image there are objects in the foreground, however these objects differ across the series of images in terms of their location. Note that some objects always exists in the foreground. The background is static. An example might be a busy tourist spot and you want to remove the people or tourist buses from the image. I'd like the software to take the series of images and as much as possible reconstruct the background. Is there software available that has this capability? If so what are the steps necessary to use that functionality? Similarly if anyone knows a lot about image processing, are there any image processing algorithms that could handle this? Thanks.

• After recovery to restore point, Windows 7 missing pinned items and favorites

  - by Michael Levy

  I believe a recent windows update was interrupted. The next day, I could not logon and was presented with the error "User Profile Service service failed the logon. User profile cannot be loaded". I followed some advice from http://answers.microsoft.com/en-us/windows/forum/windows_vista-security/help-user-profile-service-service-failed-the-logon/4ed66b21-c23e-42f1-98b2-706dcf931fae and logged in with a different admin account and used system restore to restore to a recent restore point. Most everything is working fine, but I have noticed two odd things: Any items that were pinned to my start menu or task bar were not accessible. I had to un-pin and re-pin the items. In Windows Explorer, my favorites are gone and I can't seem to add any favorites. If I browse to a folder and right click on the Favorites Icon and select "add current location to favorites" nothing is saved. I'd appreciate any explanation to understand why these things did not get recovered properly and any help fixing the favorite functionality.

• 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!

• Tab Auto-Completion in Mac OS X when using sftp in terminal

  - by AlanTuring

  i have been getting very frustrated lately since the readline functionality has been removed from MacOSX and Tab Auto-Completion doesn't work anymore. So i was wondering if anyone knew a good alternative to use that i could install so i can tab auto-complete files when sftp'd in. I heard that with-readline is a good option for this. If so, how do i get an alias sftp = with-readline sftp to work? I would like to do the same with any other option that isn't with-readline, so i don't have to assign an alias each time i set up a session. I am using Mac OS X 10.8(Mountain Lion) with Homebrew installed. Thanks in advance to anyone who can help me.

• web based source control management software [closed]

  - by tom smith

  hi. not sure if this is the right place, but hopefully someone might have thoughts on a solution/vendor. Starting to spec out a project that will require multiple (50-100) developers to be able to manipulate source files/scripts for a large scale project. The idea is to be able to have each app go through a dev/review/test process, where the users can select (or be assigned) the role they're going to have for the given app. I'm looking for web-based, version control, issue tracking, user roles/access, workflow functionality, etc... Ideally, the process will also allow for the reviewed/valid app to then be exported to a separate system for testing on the test server/environment. This can be hosted on our servers, or we can do the colo process. I've checked out Alassian/Collabnet, but any thoughts you can provide would me appreciated as well. thanks

• How do you create virtual folders from saved search

  - by Jérôme Radix

  I would like to have on unix-like platforms, the same functionality as to Windows 7 Library folders (aka virtual folders) you see in Windows Explorer. Gnome Nautilus do that kind of virtual folders through saved search. But I want a system-wide solution, not a gnome-wide solution. Is there a tool that creates virtual folders from the concatenation of multiple search queries (the result of multiple find commands ?). The solution should index files for better performances and you should be able to define the default folder for copy operations. I assume the solution of this kind of problem certainly use FUSE, but I can't see a complete solution to this kind of task in FUSE applications.

• Disable/configure Back and Forward through mouse wheel in Internet Explorer

  - by Subtwo

  I have a problem with Internet Explorer (version 7 on Windows XP). Sometimes (not always) when you use the mouse wheel to scroll a page up/down it instead chooses to go back or forth in the web browsing history. This behavior is the same as when you hold the shift-key simultaneously using the wheel. My guess is that Internet Explorer somehow gets misled by something and thinks that I'm actually pressing shift. This is in turn maybe an artifact of the fact that this particular session is a remote-desktop session originating from Linux (Ubuntu). Needless to say the problem can be quite irritating and the alternative of completely turning off the wheel functionality doesn't seem like an option as other applications would suffer greatly from this. Anyway back to my question(s): Is it possible to map the shift+wheel to a simple wheel event for Internet Explorer? Is it possible to disable the shift+wheel event for Internet Explorer? Any suggestions are greatly appreciated.

  Different Types of Home-Based Routers Exist, and those routers provide NAT Feature as well e.g; and most of them are Port Restricted. Q-1 : What kind of Base Softwares Manufactures use to develop NAT Functionality ? Q-2 : Is that Technology Proprietary ? Or some Open-Source used to develop that e.g; Firehol ? Q-3 : I am looking for a software which works exactly like a NAT,and by doing very basic configuration it should work either Symmetric NAT, Port Restricted NAT or Address Restricted NAT ? So that I can test some of my Network Application which are dependent on NAT via this way on same PC ? e.g; I can test my developed ICE Algorithms

• SMS Gateway Suggestions Needed

  - by SidC

  Hi All, Our website is written using PHP and is powered by a hosted Linux web server. We want to allow our users to receive SMS messages when they've received intranet-site messages from fellow users - SMS Notification. What is required to implement this functionality? Are there open source (free?) server applications that address this? Do we need to contract with wireless carriers to send messages to their networks? What, if any fees, must be paid to them? Thanks, Sid

• Why can't I create a Windows backup on my secondary disk?

  - by Brian Sullivan

  I've installed Windows 7 Ultimate on an SSD that I've added to the XPS desktop that I bought from Dell. I would like to use the built-in backup functionality to create incremental backups and store them on the large drive that came with the machine. I formatted the large drive and turned it into a Basic disk. However, when I try to set the backup location to the large internal disk (E:\) in the "Set up backup" wizard, a get a message saying, "A system image cannot be saved on a drive that your computer boots from or that Windows is installed on." Windows is not installed on that disk. I even deleted the OEM partition that was on the disk, and removed it completely from the boot order in the BIOS. Any clue why Windows is griping at me about this?

• How can I redirect URLs using the proxy module in Apache?

  - by LearningIT

  This seems like a super-basic question but I am having a hard time tracking down a straightforward solution, so appreciate any help and patience with me on this: I want to configure my Apache proxy server to redirect certain URLs so that, for example, a web browser HTTP request for www.olddomain.com gets passed to the proxy server which then routes the request to www.newdomain.com which sends a response to the proxy server which then passes it back to the web browser. Seems so simple, yet I don't see how to achieve this on Apache. I know Squid/Squirm offer this functionality so am guessing I am missing something really basic. I know I can use RewriteRule to dynamically modify the URL and pass it to the proxy server, but I effectively want to do the reverse, whereby the proxy server receives the original URL, applies the RewriteRule, and then forwards the HTTP request to the new URL. Hope that makes sense. Thanks in advance for any help.

• How to "paint" the data layer of a CD using a CD drive?

  - by Jens

  I am looking for software to "paint" geometric shapes, dots or lines on the data layer of a writable CD (or DVD) using a standard drive. These do not have to be visible to the naked eye; I'd try to abuse the small dot size on the CD for some scientific measurements. I am aware of the "LightScribe" feature of some drives and that is not what I am looking for. Most of the software available is of course limited to write music or data, on does not offer the low-level "place a dot at this radius, this angle"-functionality. Is there something out there for me?
