• How to debug xsane "no devices available" error on 64 bit Ubuntu 10.04

  - by BD at Rivenhill

  I have a Brother MFC-J615W printer/scanner and I wish to use the scanning feature across a network with a computer running 64-bit Ubuntu 10.04. I have installed the drivers from the Brother website and followed all of the instructions, and printing works fine, but xsane (installed from repositories) produces a popup with the message "no devices available" on startup. I recently had success with a similar approach when installing drivers for a Brother MFC-495CW on 32-bit Unbuntu 9.10, so I am aware of issues such as requiring root access if the driver permissions are not set correctly, but running xsane as root does not solve this problem. Are there any tools available to debug this problem further or does anyone have advice on how to proceed?

• Disable laptop screen

  - by Kyle

  I recently had the display fail on my Dell Inspiron E1505 laptop. I currently have my TV hooked up to the laptop's S-Video out which works fine as long as I'm running in Windows. For the first minute or so when the computer is booting I get no display. I was wondering if there was any way to disable the laptop screen entirely so that the TV display is active from the beginning (not just after Windows loads). I realize there may be a BIOS setting for this, my only problem is I can't see the BIOS settings screen since no display is active at that point so if anyone has any BIOS setting solutions I'd need the exact keystrokes to hit :)

• Linux openSUSE 11.2 on VAIO Z890T

  - by alfredozn

  I have a VAIO Z-series (VGN-Z890T) and I want to install openSUSE 11.2. I found some guides to fix the problem for the video card switch, but all for older models, those preconfigured with windows vista. It looks like newer model use a different bios configuration to support hot swap between cards in Windows 7 and this change breaks the solution to my problem. I'm not an experienced linux user, but i was using it recently on my old computer ind definitively I want it on my laptop. I installed openSUSE once and i was trying and trying to solve it until I finished reinstall again and use a fresh installation. My question is: Does anyone has installed and configured successfully openSUSE on one of the latest vaio z laptops???

• Getting started with a new iMac...

  - by Moshe

  I'm on my first Apple computer, a shiny new 21.5" iMac. I am not unfamiliar with OS X as I have been using a borrowed MacBook for a few months. Considering that this is my machine, I am more comfortable "settling in". I would like to get recommendations for software to install on it, other possible uses and whatnot. I bought it primarily for iPhone development, but I make videos on my beast of a PC using Adobe Premiere CS3. What software is recommended for me to download for the aforementioned as well as photo editing, graphic design and web design? Bear in mind that this machine will NOT have steady internet access and that I'm looking for freeware only. THANKS!

• WinXP Movie Maker Codec Error

  - by Bob Rivers

  Hi, I'm trying to use Windows XP Movie Maker, but when I try to import an AVI video, it shows an error telling me that it wasn't import due to an the fact that the codec wasn't available (I'm able to see the video using the windows media player) First, the error message suggested to enable the option "download codecs automatically" under "tools options general". I did it. But know the error tells me that the codec wasn't available and, if I already installed it, I should reinitialize movie maker. I also already did it... The error msg is: The file D:\movie1.avi cannot be imported because the codec required to play the file is not installed on your computer. If you have already tried to download and install the codec, close and restart Windows Movie Maker, and then try to import the file again. Any hint? TIA, Bob

• How to remove a partition on a USB drive?

  - by Nathan Long

  I got a free promotional USB stick that I want to format for my own purposes. When I inserted it, it automatically opened a browser and launched a web site. I have since disabled autoplay on this computer so that nothing launches when the stick is inserted. But it still shows up as two separate drives, and one of them is a "CD Drive" that I can't format. How can a USB stick contain a "CD Drive?" And more to the point, how can I remove this partition using Windows XP or Ubuntu? Update I previously asked for an XP solution, but finding none, I have tried Ubuntu, also without success. Gparted doesn't see the "CD" portion as a device at all, and from bash, any chmod changes I try tell me that the file system is read-only. Any ideas?

• pfsense multi-site VPN VOIP deployment

  - by sysconfig

  have main office pfsense firewall configured like this: local networks WAN - internet LAN - local network VOIP - IP phones need to connect remote offices (multi-users) and single remote users (from home) use IPSEC or OpenVPN to build "permanent" automatically connecting tunnels from remote location to main location. in remote locations, network will look like this: WAN - internet LAN - local network multiple users VOIP - multiple IP phones in order for the IP phones to work they have to be able to "see" the VOIP network and the VOIP server back at the main office for single remote users ( like from home ) the setup will be similar but only one phone and one computer so questions: best way to tie networks together? IPSEC or OpenVPN can this be setup to automatically connect ? any issues/suggestions with that design/topology ? QoS or issues with running the VOIP traffic over a VPN throughput, quality etc.. obviously depends on remote locations connection to some degree

• Belkin Flip KVM keyboard skip problems

  - by Craig

  I have just bought a Belkin Flip 2 port KVM. Functionally it is almost there except I have a keyboard sticking problem. So if I type the word 'Hello' it will often (about 25% of the time) output 'Hellooooooooooooooooooooo'. If I plug the keyboard directly into the USB on the computer I don't have this problem, only when plugged into the KVM. I feel like it is a USB speed problem. Followup It appears I have the same problem with the mouse, it will jump from one side of the screen to the other as I move it. The mouse is annoying but half as much as the keyboard.

• How do I totally get rid of Norton Utilities

  - by Patriot

  Alright, so I treated myself to a new computer for Christmas. Windows7 64-bit, yada yada yada. Uninstalled Norton Security using Windows7 uninstall program, installed Microsoft Security Essentials in it's place. From a cold boot, I still get the screen from Norton asking me if I wanna sign up for the free six months, which I don't. Guess Windows7 uninstall left behind some pieces. Anyone know how I can get rid of this Norton screen? EDIT: @ Revolter: Great. Used Norton Removal Tool Successfully. Now I get a different pop-up window ALWAYS reminding me if I want to activate Norton Online Backup. What does one have to do to FINALLY get rid of these people?

• How do I see what connections are being made?

  - by Coldblackice

  My DDWRT router is showing that my computer has a connection count around 600! The router is at 100% CPU use. How can I see what's making all the connections? So far, I've opened up Resource Monitor and checked the network tab. I can sort by which program is using the most network bandwidth (Pale Moon browser), but I can't see what's making all of the connections. Or rather, where all the connections are being toward (trying to find what tab must be making all of these connections). I've also tried netstat -A, but it apparently doesn't show the actual number of connections being made. At least, the list of established connections isn't very long, by any means (like enough to account for the 500+ connections apparently being made.

• How can I stop Ubuntu from playing audio from 2 interfaces at the same time?

  - by Solignis

  Hi there, I just loaded Ubuntu 10.10 Maverick on my home machine. The machine is running a Core2Duo E6750 on an MSI motherboard with an Nvidia GTX260-OC Graphics card. The problem I am having as stated in the title is for some reason Ubuntu is playing audio through my headphone coming out from the computer and it is also playing the audio at the exact same time through the HDMI connection coming out of the graphics card, it has a plug to allow this. What is going on, I have never seen this before. Most importantly of all can it be fixed so that I can sepertate the 2 interfaces, the one is a standard PC audio IO and the HDMI one is connected through the mobo's internal SPDIF. More information can be provided if required.

• Can't download updates for reinstalled Office 2000 on WinXP OS "expected version not found" error message

  - by mpmadigan

  I replaced HD and reinstalled WinXP Pro and successfully downloaded all of the service packs and security updates. I've reinstalled my licensed version of Office 2000 (upgrade version from Office 97). The software installs and is functional; but when trying to install updates SR-1 or SR-1a or any individual security update I get error message "expected version of product not found". Microsoft no longer provides support for this legacy version of office. I can't find any support documents in Microsoft's database that addresses this issue. This is my sister's computer and I've already come out-of-pocket $100 for hardware (not counting the $$hours of labor). She only uses MS Word for minimal correspondence. No desire to spend $100+ for new version of Office. I would greatly appreciate any suggested fixes for this problem.

• Is it possible to rate-limit an scp/sftp/rsync/etc transfer from the command-line? ie, manual QoS on

  - by warren

  Specifically, I am looking to rate-limit an scp or sftp session (or other arbitrary network call) in the call itself. For example, let's say I want to copy 100MB to one server, and 1GB to another. I'd like to be able to run both of these at the same time, but maintain a QoS for "normal" computer usage - somewhat similar to how you can rate-limit bittorrent. Is there a way to do this without touching the networking hardware? I'm envisioning something akin to: magic-qos-tool 'scp file user@host:/path/to/file' Or.. scp -rate 40kbps file user@host:/path/to/file

• Declarative programming vs. Imperative programming

  - by EpsilonVector

  I feel very comfortable with Imperative programming. I never have trouble expressing algorithmically what I want the computer to do once I figured out what is it that I want it to do. But when it comes to languages like SQL or Relational Algebra I often get stuck because my head is too used to Imperative programming. For example, suppose you have the relations band(bandName, bandCountry), venue(venueName, venueCountry), plays(bandName, venueName), and I want to write a query that says: all venueNames such that for every bandCountry there's a band from that country that plays in venue of that name. In my mind I immediately go "for each venueName iterate over all the bandCountries and for each bandCountry get the list of bands that come from it. If none of them play in venueName, go to next venueName. Else, at the end of the bandCountries iteration add venueName to the set of good venueNames". ...but you can't talk like that in SQL and I actually need to think about how to formulate this, with the intuitive Imperative solution constantly nagging in the back of my head. Did anybody else had this problem? How did you overcome this? Did you figured out a paradigm shift? Made a map from Imperative concepts to SQL concepts to translate Imperative solutions into Declarative ones? Read a good book? PS I'm not looking for a solution to the above query, I did solve it.

• Command-line access to remote MySQL server

  - by Jerry Krinock

  I administer a website on a remote, shared host. My web host offers MySQL, and I am able to access this from my Mac OS X computer using a GUI program, Sequel Pro. That works great. But I want to script some queries, and Sequel Pro is not scriptable. What should I do? I've read about tunneling to mysql via SSH. I have shell access to the server, with an SSH key on my Mac, so ssh [email protected] -p 7978 gets me in. Should tunneling the MySQL port 3306 work? Like this? ssh [email protected] -L 3306:127.0.0.1:3306 (It "times out" after a minute.) Do I need to install mysql on my Mac?

• SQL SERVER – Download SQL Server Product Documentation

  - by pinaldave

  Today I just returned from Bangalore User Group Meeting. Attending User Group meeting is indeed fun and really great experience. The best part of the User Group is meeting like minded people and have a great conversation with them. During the meeting I was asked why one has to go online to access SQL Server Product Documentation. I can clearly see there can be many reasons for why one wants the documentation to be available offline. The reasons can be anything but not limited to Company Firewall No Internet (power failure, on road or disaster) Internet Bandwidth Limitatoin Company Proxy Issues … and much more… In this kind of situation one needs documentation which is offline and easily available in local computer. The Microsoft SQL Server 2012 setup installs only the Help Viewer and related components for managing Help settings. Setup does not directly install any documentation. All of the SQL Server documentation is available online. Well, Microsoft has recently released Production Documentation available for offline users as well. You just have to download the executable file and follow all the instructions. Please follow the link below for download of the file. There is detailed instruction on how to download and install the documentation offline. Product Documentation for Microsoft SQL Server 2012 Reference: Pinal Dave (http://blog.sqlauthority.com) Filed under: PostADay, SQL, SQL Authority, SQL Documentation, SQL Download, SQL Query, SQL Server, SQL Tips and Tricks, T SQL, Technology

• Mac - Run java program at launch

  - by emd

  I want to launch a java program (server program) at computer start up. I can run it from the command line perfectly. I created /Library/Server/startFS.sh.

I have tried prepending 'nohup' and post pending '&', but no combination seems to work. Help please.

• Dell Docking Station Doesn’t Detect USB Mouse and Keyboard

  - by Ben Griswold

  I’ve found myself in this situation with multiple Dell docking stations and multiple Dell laptops running various Windows operating systems.  I don’t know why the docking station stops recognizing my USB mouse and keyboard – it just does.  It’s black magic.  The last time around I just starting plugging the mouse and keyboard into the docked laptop directly and went about my business (as if I wasn’t completing missing out on a couple of the core benefits of using a docking station.)  I guess that’s what happens when you forget how you got yourself out of the mess the last time around.  I had been in this half-assed state for a couple of weeks now, but a coworker fortunately got themselves in and out of the same pickle this morning.  Procrastinate long enough and the solution will just come to you, right? Here’s how to get yourself out of this mess: Undock your computer Unplug your docking station Count to an arbitrary number greater than 12.  (Not sure this is really required, but…) Plug your docking station back in Redock your machine I put my machine to sleep before taking the aforementioned actions.  My coworker completely shutdown his laptop instead.  The steps worked on both of our Win 7 machines this morning and, who knows, it might just work for you too.

• What is the definition of "Big Data"?

  - by Ben

  Is there one? All the definitions I can find describe the size, complexity / variety or velocity of the data. Wikipedia's definition is the only one I've found with an actual number Big data sizes are a constantly moving target, as of 2012 ranging from a few dozen terabytes to many petabytes of data in a single data set. However, this seemingly contradicts the MIKE2.0 definition, referenced in the next paragraph, which indicates that "big" data can be small and that 100,000 sensors on an aircraft creating only 3GB of data could be considered big. IBM despite saying that: Big data is more simply than a matter of size. have emphasised size in their definition. O'Reilly has stressed "volume, velocity and variety" as well. Though explained well, and in more depth, the definition seems to be a re-hash of the others - or vice-versa of course. I think that a Computer Weekly article title sums up a number of articles fairly well "What is big data and how can it be used to gain competitive advantage". But ZDNet wins with the following from 2012: “Big Data” is a catch phrase that has been bubbling up from the high performance computing niche of the IT market... If one sits through the presentations from ten suppliers of technology, fifteen or so different definitions are likely to come forward. Each definition, of course, tends to support the need for that supplier’s products and services. Imagine that. Basically "big data" is "big" in some way shape or form. What is "big"? Is it quantifiable at the current time? If "big" is unquantifiable is there a definition that does not rely solely on generalities?

• LibreOffice - Can't drag and replace images [LibreOffice 3.5 and 3.6, Ubuntu 12.04]

  - by Anderxale

  My wife uses LibreOffice to create catalogues of a couple hundred items and then converts it to PDF. Man we love LibreOffice! Anyway I set up Windows-7 and Mint-14-Mate dual boot for her to ease into Linux. Today she was ready for Ubuntu and so I did a clean install on her machine. Everything was smooth but today when she tried to work she ran into an issue... She used to be able to download a folder full of images to use in her catalogues and then update her catalogues by replacing old images with new ones. It was so simple - Open an old catalogue, save with a new date, drag and drop replace images of items that no longer exist. The drag and drop process would scale the image and then crop it horizontally or vertically to fit. Now that I have installed Ubuntu 12.04 for her she can no longer replace images, it just does nothing... If she drags the image to the left or right of the original it appears next to the original so I know d&d works, unfortunately it does not resize or crop the image. I tried this on my laptop and my desktop... same thing! I then tried updating the LibreOffice to 3.6, no change. I then tried opening a virtual machine windows xp and Mint 14 on this computer and tried with 3.6 in those operating systems and it worked. Can anyone help? I have a lot of hope that there is an answer because Mint is based on Ubuntu/Debian and that distro can perform this task successfully! Sorry about writing a book....

• Line Numbering in Notepad-Week 41

  - by OWScott

  You can find this week’s video here. Notepad is so simple, yet so useful. Yet, at times the "Go To" appears to break and doesn't work as expected. This week's video is short and sweet. Learn about line numbering in notepad. One of my all-time favorite applications is notepad. You may think I’m joking, but I’ve grown quite fond of notepad over the years. Like a faithful friend, always there for you when you need it. Whether it’s an old computer or new, it opens instantly. I can’t remember notepad ever crashing. Wish I could say that for most other applications. This week’s lesson is a quick one, but if you’ve ever run into issues with line numbering in notepad, I hope you find it useful. I remember the first time the “Go To” feature didn’t work in notepad for me. It took me a while to figure it out so I hope to save you the grief that I went through. Watch this week’s video for a couple quick tips on the tried and true notepad. This is now week 41 of a 52 week series for the web pro. You can view past and future weeks here: http://dotnetslackers.com/projects/LearnIIS7/ You can find this week’s video here.

• Unable to find a disable button for pop-up bubbles in 2.8.0.851

  - by Greg Richards

  I'm still using 2.8.0.722 on my Mac while a friend has upgraded to 2.8.0.851 The newer version on her computer has pop-up bubbles for every chat message when the chat window is minimized. Neither of us are able to find where to disable this feature. The difficulty arises when we minimize a chat window, but the bubbles continue to show everything the other person is typing, even when one of our kids is with us for a moment looking at something else on the screen. We have checked all throughout the Preferences settings, most notably the privacy and chat areas, to no avail. Ultimately we would like to disable these chat pop-up bubbles so that when a chat window is minimized, that conversation and all incoming messages will remain private until we restore that chat box to be viewable on the screen again. Thanks! Greg

• What changes does McAfee make to the registry?

  - by AUTO

  I'm wondering if anyone knows exactly what McAfee does to the registry. I've got a computer on which JavaScript no longer works. I read online that McAfee replaces the script interpreter dll path in the registry to point to its own dll, which filters, and in turn calls the official "jscript.dll". I found multiples of these in the registry, and corrected them, but it still hasn't fixed the problem - JavaScript still does not work. I'm considering just reinstalling, and then re-uninstalling McAfee to fix it. However, for the record, I still want to know if anyone has, or can provide an online list of all the changes McAfee makes to the registry. Details: Windows 8 x64I found these JScript registry changes: HKEY_CLASSES_ROOT\CLSID\{f414c260-6ac0-11cf-b6d1-00aa00bbbb58} HKEY_CLASSES_ROOT\CLSID\{f414c261-6ac0-11cf-b6d1-00aa00bbbb58}
