• How to get OpenSSH to use ksshaskpass under KDE?

  - by Guss

  When using a GNOME desktop on Ubuntu, if I use OpenSSH client to connect to another computer (running from the gnome-terminal), I get a single graphic popup asking for my private key's pass-phrase. After that I no longer need to enter my pass-phrase as it is cached by the SSH agent. Under KDE it doesn't work like that - when I start ssh from konsole, I get a text prompt for my pass-phrase every single time, even though ssh-agent is running. If I run ssh-add from the terminal then I can enter my pass-phrase on the terminal and it will be stored by ssh-agent and I won't get any more pass-phrase prompts, while if I run ssh-add the KRunner graphical command line ("Run" dialog) then I get a graphical prompt with the same behavior. The problem is I have to remember running ssh-add every time I log in to the desktop. How can I get ssh to behave under KDE, the same as it does on GNOME - the first time the pass-phrase is needed, pop up a graphical dialog and store the pass-phrase in the agent. I've installed ksshaskpass, but that didn't change anything.

• Which algorithms/data structures should I "recognize" and know by name?

  - by Earlz

  I'd like to consider myself a fairly experienced programmer. I've been programming for over 5 years now. My weak point though is terminology. I'm self-taught, so while I know how to program, I don't know some of the more formal aspects of computer science. So, what are practical algorithms/data structures that I could recognize and know by name? Note, I'm not asking for a book recommendation about implementing algorithms. I don't care about implementing them, I just want to be able to recognize when an algorithm/data structure would be a good solution to a problem. I'm asking more for a list of algorithms/data structures that I should "recognize". For instance, I know the solution to a problem like this: You manage a set of lockers labeled 0-999. People come to you to rent the locker and then come back to return the locker key. How would you build a piece of software to manage knowing which lockers are free and which are in used? The solution, would be a queue or stack. What I'm looking for are things like "in what situation should a B-Tree be used -- What search algorithm should be used here" etc. And maybe a quick introduction of how the more complex(but commonly used) data structures/algorithms work. I tried looking at Wikipedia's list of data structures and algorithms but I think that's a bit overkill. So I'm looking more for what are the essential things I should recognize?

• Macbook cannot see specific wireless network after being connected to it for a while

  - by donut

  Okay, so there's a single wireless network that my laptop has troubles with. My Macbook Pro used to be fine with it until it changed to using channel 13 (or 11?). Since then, after being connected to it for a while it disappears from my laptop's view. Other networks are showing up fine and other computers (including several Macs) have no troubles connecting to this network. If I clear my system cache using Onyx and then restart (sometimes a couple times) my laptop can see and connect to it again. But it seems that if I disconnect and try reconnecting I have to clear my cache again. One thing to note is that if I put my computer to sleep while connected to this network it has no problems reconnecting on wake up. I've got a 15" Macbook Pro 2,2 with Leopard 10.5.8.

• How to assign hotkeys in OSX-snow-leopard

  - by 2816

  I am trying to assign a hotkey to open a folder in snow leopard. For example, in windows i could simply press the Windows+E to open the My Computer folder (or manually assign whatever folder i wanted to open). Is there a way to get this same behavior in OSX? I want to be able to launch applications, and open folder with my own keyboard mappings. For launching applications I use automator, create a service that receives no input to 'launch application' (from the utilities library). Then i can assign a keyboard shortcut to this service. Now i can launch applications with keyboard shortcuts. I still dont know how to open a folder. I know this can be done using quicksilver - but am looking for an organic approach that does not require any additional installs.

• Mouse for a lefty?

  - by Kyralessa

  As a programmer, I'm fairly particular about my keyboard and mouse. One thing I've only recently noticed is that the mice I tend to prefer don't work well for my five-year-old. He's left-handed, but ends up mousing with his right hand on the computer because (a) that's where the mouse is, and (b) most mice are designed for right-handed people anyway. So, a couple of questions: If you're left-handed and you mouse with your left hand, do you have any recommendations on good mice? If you have a lefty in your household (whether or not it's you), is there an easy way to swap settings between left-handed and right-handed mouse buttons? One way is Control Panel Mouse Check the box on the first tab OK. Do you know of anything faster? Or, better yet, what I'd really like is a way to reverse those settings on only one particular mouse, which would be designated as my son's mouse.

• Why does iTunes sometimes loose everything in the library when upgrading?

  - by Rod

  All of my kids have experienced problems at one time or another, when upgrading iTunes on their laptops. The version number doesn't matter, as this has happened for the last couple of years, so the version number has changed. It isn't consistent. What is consistent is sometimes, but not always, after upgrading iTunes, it will have lost all of it's information about the music, podcasts, etc, that it had. And yet if I bring up Windows Explorer, I can find all of it there. It's a pain to have to recover that. The pertinent question is, how do you recover all of the music, podcasts, playlists, etc, that is on the computer, but iTunes doesn't show it in the library? Second, what causes iTunes to do this in the first place?

• Driver choice for addressing ubuntu wireless card issues

  - by Holly

  Hello, this should be a relatively simple question. I'm attempting to get my windows wireless card to work with ubuntu, booted from my portable hard drive. This is the guide I'm attempting to follow is on help.ubuntu.com, /community/WifiDocs/Driver/Ndiswrapper My wireless card is a Broadcom Corporation BCM4318 AirForce One 54g 802.11g Wireless LAN Controller. My computer is an HP Pavilion Entertainment dv5 notebook, which came with Vista 64. I would like confirmation about which of the drivers I should use. At this point, I'm leaning towards Broadcom BCM4318 HP Pavilion zv6000, but I thought it best to ask advice before taking action. The drivers I have to chose from are listed on this page http://sourceforge.net/apps/mediawiki/ndiswrapper/index.php?title=Category:Broadcom Thanks! Holly

• Network really slow with TL-WN951N wireless card

  - by Sam

  I literally just installed ubuntu and it seems to be working great except the network is deadly slow. I'm running a TL-WN951N wireless card which can download at about 600-700 KB/s in windows but in Ubuntu the max speed it seems to get is around 5KB/s. I guess I should note that my WAP is only wireless-G but like I said, I can get much better speeds in Windows. I'm testing the speeds by downloading files from here: http://mirror.internode.on.net/pub/test/ Anyone have any idea? I saw some people recommend downloading drivers and compiling them myself but I'm really really new to all of this so would appreciate someone babying me through it so I don't brick my computer!

• Where did this incorrect cached DNS lookup come from?

  - by Stephen Jennings

  Somehow, I've been having a chronic issue where my computer will get an invalid DNS lookup in its cache for either of the two Exchange servers I use from Mail.app. My workplace runs one of the Exchange servers and I run the other (they are totally unrelated, hosted by different companies, etc.). The problem manifests as a certificate domain error. When it happens, I can run nslookup mail.mydomain.com and I see the incorrect IP address (usually owned by either Apple or Akamai), but if I run nslookup mail.mydomain.com 8.8.8.8, I get the correct address. My real quest is to find out why this keeps happening, and to do that, I'd like to know which server is supplying me this bad DNS entry. Is there a way to check my DNS cache to see where this bad lookup came from?

• How to diagnose very slow pagefile

  - by svick

  Quite often, one of the applications I use freezes (“does not respond”) for a while, in extreme cases for few minutes. This happens especially when when switching apps. During this time, the HDD light flashes constantly and perfmon show that HDD is used 100% of the time (OTOH, CPU isn't) and that pagefile is being read (which is to be expected when switching apps), but at a very slow rate. When I sort the disk table in perfmon by read or write, the file read and wrote the most is the pagefile, but it's still quite low rate (I don't remember the numbers). How can I diagnose what's causing this? I use Windows Vista, and the computer is quite ordinary two years old laptop.

• Windows 7 / Media Center lock problem

  - by ICTdesk.net

  Hi, we have a Win7 with Media Center that is connected to a large screen. It displays a corporate slideshow near the coffeemachine. When the computer is started it automatically logs in and starts the slideshow. The problem is that on irregular time intervals (once a day, some days not) the slideshow stops and it switches to the login screen and shows which user is logged on. We don't know why this is happening. We first thought someone on the network was trying to open RDC connection to the machine, because it is the same sympthon like when you take over a machine by RDC with a different user, but nobody is doing that. Screensaver is disabled, energy settings "always on" Anybody ideas why this is happening?

• Java 6.0 Virtual Machine re-caches application on every load

  - by David Neale

  I have a Java application which is loaded and cached by the JRE and for most users it only needs to cache once unless the application software has changed. However, I have one computer that caches the entire application every time they load it. It is not the version of the JRE, I have that running on other machines. It also works on this machine if logged in as a local admin, just not as a standard user. Does anybody have any ideas on what might be causing this?

• How can I make PDFs appear life-size when displayed at 100%?

  - by ændrük

  When I open a letter size PDF and then zoom to 100%, the page physically displayed on my monitor is smaller than a real letter size sheet of paper. How can I make "100%" on the computer screen correspond with "100%" in real life? Details This message suggests that I should be investigating the system-wide DPI settings for my monitor. xdpyinfo reports: dimensions: 1024x768 pixels (271x203 millimeters) resolution: 96x96 dots per inch My monitor has a native display resolution of 1024x768 pixels and a diagonal display size of 12.07 inches. PX CALC returns the following information: DPI: 106.05 Dot Pitch: 0.2395mm Size: 9.66" × 7.24" (24.53cm × 18.39cm) What I've tried so far Running xrandr --dpi 106.05 successfully caused my PDF to appear actual size at 100%, but this effect was lost after rebooting. To make the setting persistent I tried creating the following /etc/X11/xorg.conf: Section "Monitor" Identifier "ThinkPad X60 LCD" DisplaySize 245 183 EndSection Section "Screen" Identifier "Screen0" Monitor "ThinkPad X60 LCD" EndSection After re-logging in, /var/log/Xorg.0.log contained [ 1167.824] (**) intel(0): Display dimensions: (245, 183) mm [ 1167.824] (**) intel(0): DPI set to (106, 106) but xdpyinfo still reported dimensions: 1024x768 pixels (271x203 millimeters) resolution: 96x96 dots per inch and "100%" still appeared too small.

• Dell Vostro 1000 w/fresh XP Pro installation running very slow

  - by ssvarc

  I'm working on a Dell Vostro 1000 laptop. It was running slowly and hanging, antivirus scans turned up nothing and the same with the Dell diagnostics (DFT hung - but Dell's diagnostics gave the HD a pass) so I imaged the HD and installed XP Pro on it. The laptop is still slow! (It takes a noticeable delay to enter words into the Google search box in IE and the computer hangs every time it enters the XP screensaver.) What are the likely possibilities at this point and how would I go about checking for them?

• Very long DNS lookups inside my network

  - by Nuno Cordeiro

  Ever since I installed DD-WRT (v24-sp2 08/07/10 std-usb-ftp) on my router (RT-N16), my browsing got substantially slower. Using FirePHP I figured out that it's being caused by VERY long DNS lookups (~30 seconds). When the domain name was very recently accessed then speed is very good. I tried changing DNS on the computer and I tried messing around with the options on DD-WRT. I have tried to configure the router with Google DNS and/or OpenDNS. My current DNS output after using ipconfig -all is: 192.168.1.1 208.67.220.220 8.8.8.8 208.67.222.222 Can someone help me debug and solve this problem? I'd like to snoop the requests themselves. How can I know which DNS requests are being sent and which are failing/succeeding? Note: I don't expect this to be relevant but my router is connected to the internet through an ONT.

• email to sip voicemail

  - by alfredwesterveld

  Hi all, I don't know if this is the correct place to answer this question, but here it goes. I have been googling for a cheap email to sip voicemail service. That is because I have got a Linksys/Cisco SPA-941 phone which has a led which will light up when a new message comes in inbox(somebody calls me). So what I want is the following. I want the e-mail(title only is enough) recorded(By computer voice) and sent to my phone which I can playback when the led lights up. Like I said above I was unsuccessful googling for a service like this and I hope somebody knows if this service exists. Many thanks, Alfred

• SharePoint 2010 not seeing Active Directory users

  - by user117927

  I'm pretty new to Active Directory and SharePoint but I was given to understand they are supposed to play well together. Now I have successfully set up AD with multiple user accounts that work on any member computer. I have also successfully installed SharePoint 2010 Server on an AD machine. Both the AD server and SharePoint servers are on separate machines (VMs running on ESXi to be precise). I can only log on with user accounts I create on the local server. Furthermore the user browser thing for adding users will only see local users. I've followed the advice here http://technet.microsoft.com/en-us/library/cc262350.aspx#section2 for Classic authentication and also NTLM claims based authentication but to no avail. Is there something fundamental I am getting wrong here? I'd be really thankful for any help you can lend me; I've been googling and scratching my head for a couple of days now. P

• Controlling an amplifier power supply from Squeezebox/SqueezeCenter

  - by teabot

  I have a Squeezebox that is connected to an amplifier. I'd like the amplifier to switch on/off whenever the Squeezebox is powered on/off. I don't mind writing some plugin code to SqueezeCenter to do this but in hardware terms I am looking for off-the-shelf components. I imagine that I need some kind of Ethernet controlled power outlet. I have looked at X10 (I can't bring myself to link to their terrible site), but their product range seems extremely confused and it looks as though I'd have to use both RF and comms-over-mains to implement a computer controlled socket. Does anyone have any alternative suggestions? Note: Any components should be available and certified for use in the UK.

• Ghost Image - windows asks for activation on when deployed to VM

  - by Chris Sobolewski

  I have several images created with Ghost Solution Suite (v11 I believe), the images have been in use for a few years now, but I am finally to the point where I have enough time to attempt to virtualize them for easier updates. I am running VMWare and attempting to image the virtual machines with my ghost image files. For my images I am running sysprep with minisetup and using reseal. The image deploys successfully, however when I start the VM for the first time, it demands windows activation. This doesn't happen when I image a physical computer, even a different model with different hardware. The idea of virtualizing my images becomes rather worthless if I am unable to deploy the images without having to activate every time (especially as Microsoft keeps declaring our volume licence key as invalid for activations). Does anyone know why it is asking for activation on a virtual machine, but not a physical PC? How can I prevent this?

• Windows 7 offline files - work temporarily offline even if network connection works

  - by Robert

  Sometimes I am connected via VPN to a network containing the server where files are stored which are cached by Windows offline files feature. Sometimes the connection works good and working this way is not a problem - on other times working is quite a pain because of high latency when working with the files in the Windows explorer. Is there an interactive way how a user (with admin permissions) can temporary suspend online usage of offline files? I already activated the "Transparent caching" group policy feature (Computer Configuration Policies Administrative Templates Networks Offline Files) with a network latency of 200msec but from my experience even if I get ping times to the file server of less than 40msec online usage is quite tenacious. Setting low latency times at this point causes the offline files often to toggle which makes problems with some applications working with several files and requires them to be consistent (like SVN client).

• Citrix ICA Client on Mac shift key doesn't work as expected.

  - by brianegge

  When I'm connected to a Windows XP computer from my Mac OS X 10.6 using the Citrix ICA Client, it seems that the shift key only works for the first letter typed after pressing shift. In order to type multiple uppercase letters, like ICA, I must either press caps lock, or press and release shift before each character. I've tried switching between standard and enhanced keyboard, as well as the 'Send Special Keys Unchanged' option, but none of these seem to affect the issue. The problem doesn't occur when I switch from the Citrix window to a regular Mac window.
