• Virtualbox two networks slow

  - by Petr Marek

  I am running an Ubuntu server guest on Win 7 guest, and am running a webrick server (RoR dev). If I have just a host-only network, everything works fine and the browser response is instant. However, if I add a second network (NAT), so that the server can connect to the internet (for various updates etc.), the host-to-guest access gets really slow. I can't use the bridge connection. I am using the port 3000 (RoR Webrick server) and connecting to the guest via internet browser on this port (eg http://192.168.56.102:3000). Any idea, what could be causing this? If I ping the IP from host console, I get < 0ms. Here are the settings (relevant info is in english; Povoleno vše is Everything is allowed):

• Deleting entire lines in a text file based on a partial string match with Windows PowerShell

  - by Charles

  So I have several large text files I need to sort through, and remove all occurrences of lines which contain a given keyword. So basically, if I have these lines: This is not a test This is a test Maybe a test Definitely not a test And I run the script with 'not', I need to entirely delete lines 1 and 4. I've been trying with: PS C:\Users\Admin (Get-Content "D:\Logs\co2.txt") | Foreach-Object {$_ -replace "3*Program*", ""} | Set-Content "D:\Logs\co2.txt" but it only replaces the 'Program' and not the entire line.

• Win7 glass-like Aero feature - unable to enable

  - by user24752

  I have a 4 months old PC with Win7 Home Premium x64. Windows Experience Index is 5.4. Intel i5 processor 6GB memory nVidia GT220 video card. During games, Windows reported shortage of system resources, so switched the desktop back to "Windows 7 Basic" desktop theme. After game-over, I could switch back to the normal theme and enjoy all Aero eye-candies. However, lately the glass-like window transparency feature got disabled, and I found no ways to enable it again. There is a Troubleshouting option in Control Panel saying: "Find and fix problems with transparency and other visual effects". If I launch that, it does not find anything. Event viewer is full with the following warnings: The Desktop Window Manager is experiencing heavy resource contention. Scenario : The Desktop Window Manager responsiveness has degraded. Taskbar, window borders, etc, none of the other transparent features work, and I cannot turn them on. Any thoughts?

• How to migrate ScrapBook data to Evernote?

  - by Daren Thomas

  I have tons of info stored in a ScrapBook (the Firefox plugin) installation at home. But thats my problem: It's at home! I'd just love to be able to post all that stuff to Evernote. In fact, synching would be best, since ScrapBook has some really cool editing features for websites... Has anyone gone that route?

• How do I export calendar events in Mozilla lightning

  - by Andrew Grimm

  How do I export calendar events in Mozilla Lightning? I'm using Thunderbird 3.0.4. (Sorry for such a basic question, but clicking on "Help contents" takes me to http://support.mozillamessaging.com/en-US/kb/ , and searching the knowledge base for lightning export got zero hits, and searching for export only got one irrelevant hit)

• Trouble installing Lagarith Lossless Codec (Codec Removal?)

  - by Xeoncross

  I had been using the Lagarith Lossless Codec with camstudio on Windows XP Pro SP3 for a little while before I switched to Ubuntu. Now I'm back trying to do something on windows and the codec is now missing. I tried to install it via the .exe and even manually with the .inf but it's not being listed by camstudio as installed. I'm wondering if one of the other codecs I installed might have messed with it and yet some of the files are still fine so whatever method the installers use to check for existing files before install is returning positive and not re-installing it. How can I get Lagarith to work again? Maybe I need to know how to uninstall codecs.

I would, that the fields from the profile even when creating a user are displayed. Thanks a lot!

• Why does redirecting "sudo echo" stdout to a file not give root ownership?

  - by orokusaki

  I'm pretty new to using Linux heavily, and I'm trying to learn more about file ownership and permissions. One thing that I stumbled on just now was exactly what the title says, running: weee@my-server:~$ sudo echo "hello" > some-file.txt weee@my-server:~$ ls -lh total 4.0K -rw-rw-r-- 1 weee weee 6 Dec 5 21:21 some-file.txt The file is owned by me, whereas touch works like one would expect: weee@my-server:~$ sudo touch other-file.txt weee@my-server:~$ ls -lh total 4.0K -rw-r--r-- 1 root root 0 Dec 5 21:22 other-file.txt How can I force the file to be created by root? Do I simply have to create the file in my homedir, then sudo chown root... and sudo mv ... move it to /var where I need it to be? I was hoping there'd be a single step to accomplish this.

• Asterisk/FreePBX: Allow other Google Talk clients to ring when using motif module

  - by larsks

  I've recently installed FreePBX to act as a link between a SIP soft phone and my Google Talk account. It was easy to set up and outbound calls work just fine, but I've run into two problems with inbound calls that I'm not sure how to resolve. I'm using an inbound route to forward all calls from Google to my soft phone. If the soft phone is not currently registered, Asterisk answers and immediately generates a fast-busy signal (reporting CHANUNAVAIL in the logs), and the call is lost. If the soft phone is registered, Asterisk "answers" the call before rining the soft phone, which means that other Google Talk clients never ring (since from their perspective someone has answered the call). For solving (1) seems like I could use the ChanIsAvail() function (or this answer) to prevent Asterisk from answering in the event that the phone isn't registered. However, I'm not sure what to do about (2), because the behavior I want is for Asterisk to not "answer" the call until I answer the call on the soft phone. How do I configure Asterisk (ideally within the FreePBX framework) such that I can continue to receive calls at other Google Talk clients in addition to forwarding them to a SIP phone?

• Automate uploading of videos to YouTube

  - by John

  Here's the problem: I would like to keep lots of home made videos. Of course, they are subject to being lost, or somebody could steal the the computer, or water or fire could destroy them. Secondly, I have to plug in my hard drive every time I want to watch something, which I find slow and cumbersome. I was thinking that perhaps I could upload the videos to Youtube with the privacy set to invite only and then delete the video from the hard drive automatically. Could this be done?

• which factors determines the speed of a processor? [closed]

  - by Deb

  I think that clock rate of processor determines the speed of core, in my case it is 1.86GHz. But If I am not wrong, it also determines that how much energy it will consume. If you have more frequency then more power it will consume. I choose Power Saver scheme to increase my battery life, however it reduces my core speed to half of the actual speed. I understand this happens because of SpeedStep, but I don't see any slowdown of my computer. So my problem is why we have such high frequency cores as it uses too much power. We can use low frequency cores. Actually I get confused between the two terms Speed of the processor and its frequency. So how much important is the frequency of core in case of any processor.

• What's up with stat on MacOSX/Darwin? Or filesystems without names...

  - by Charles Stewart

  In response to a question I asked on SO, Give the mount point of a path, one respondant suggested using stat to get the device name associated with the volume of a given path. This works nicely on Linux, but gives crazy results on MacOSX 10.4. For my system, df and mount give: cas cas$ df Filesystem 512-blocks Used Avail Capacity Mounted on /dev/disk0s3 58342896 49924456 7906440 86% / devfs 194 194 0 100% /dev fdesc 2 2 0 100% /dev <volfs> 1024 1024 0 100% /.vol automount -nsl [166] 0 0 0 100% /Network automount -fstab [170] 0 0 0 100% /automount/Servers automount -static [170] 0 0 0 100% /automount/static /dev/disk2s1 163577856 23225520 140352336 14% /Volumes/Snapshot /dev/disk2s2 409404102 5745938 383187960 1% /Volumes/Sparse cas cas$ mount /dev/disk0s3 on / (local, journaled) devfs on /dev (local) fdesc on /dev (union) <volfs> on /.vol automount -nsl [166] on /Network (automounted) automount -fstab [170] on /automount/Servers (automounted) automount -static [170] on /automount/static (automounted) /dev/disk2s1 on /Volumes/Snapshot (local, nodev, nosuid, journaled) /dev/disk2s2 on /Volumes/Sparse (asynchronous, local, nodev, nosuid) Trying to get the devices from the mount points, though: cas cas$ df | grep -e/ | awk '{print $NF}' | while read line; do echo $line $(stat -f"%Sdr" $line); done / disk0s3r /dev ???r /dev ???r /.vol ???r /Network ???r /automount/Servers ???r /automount/static ???r /Volumes/Snapshot disk2s1r /Volumes/Sparse disk2s2r Here, I'm feeding each of the mount points scraped from df to stat, outputting the results of the "%Sdr" format string, which is supposed to be the device name: Cf. stat(1) man page: The special output specifier S may be used to indicate that the output, if applicable, should be in string format.

But now on booting instead of raid bios system bios showed Warning : something like cannot load add on rom for vendor id xxxx device id xxx . Whats wrong ? As the card is VT6421A based and i added VT6421A bios got from VIA website.

Any easy way to do this without iterating through the objects in the vhost delete?

• Canon MF3200 Printer Problems

  - by Derick K.

  I bought a Canon MF3200 and used it on an old Windows laptop. The laptop broke, and now I'm trying to setup the printer on a laptop with Windows 7. I downloaded the new driver, and Windows was able to install it and mark it "Ready to Go." But whenever I try to print, an error comes up and it doesn't print. I tried to troubleshoot, to no avail. What else can I do? Any ideas on what the error might be?

• Can VLC stream a YouTube video?

  Is it possible to stream a particular YouTube video's content with VLC? The scenario is that you could paste a YouTube URL into a VLC dialog, and then have VLC stream the video as if it were a local media file. Any existing features in VLC, or workarounds that you know of to accomplish this streaming idea?

• how to reference a ppp adapter in windows command?

  - by ollydbg23

  When using the windows command ipconfig /all, the result will show a PPP adapter followed by a long name closed with braces. It looks like the below image: When I try to set the DNS of my PPP adapter, I encounter this problem: netsh interface ip set dns "PPP adapter {1C43A7B0-1173-40E2-96D6-1DA6457786B0}" static 208.67.222.222 Invalid interface PPP adapter {1C43A7B0-1173-40E2-96D6-1DA6457786B0} specified. I have also used the pure string "{1C43A7B0-1173-40E2-96D6-1DA6457786B0}", but with the same result. How can I reference this PPP adapter, so that I can change its configured DNS and other settings? What does this long string mean? I do not have this PPP adapter connection on my "show all connections" panel, because I have a VPN app - when running it, this PPP adapter will be automatically created for me.

• Launch an arbitrary application with a specific icon

  - by Camilo Martin

  I'm thinking about customizing my Windows 7's application icons, so that they all follow a specific theme (Token-like icons). This would involve using Resource Hacker (or similar) to patch each .exe. Not only this would be tiresome, but also it would require doing it again at each update of each application (nevermind that some could break just because it was tampered with). Instead, is there any way to launch an application with a specific icon? Ideally it would be something from the command-line (so I can make a shortcut), like this: launchwithicon.exe --app C:\myapp.exe --icon C:\myicon.ico Note that while it is possible to do something similar by setting the taskbar to "always combine, hide labels", I do not like this approach and instead am looking for something that works without combining the taskbar icons.

• Why would Firefox not be able to visit Google anymore?

  - by Edward Tanguay

  Lately I've noticed that my Firefox Browser was taking a long time when I would search Google, e.g. 3 seconds before I would see any results. If I search for a three-word phrase, it just hangs trying to connect: I removed all add-ons but it still does this. I thought it might be something with my router, but Chrome, Safari, Opera and Internet Explorer all work fine. Bing works fine in Firefox. Here's my Firefox version information: Otherwise I can still use Firefox, e.g. I'm using it to post this question, but I do notice that when I browse with it, images are often "broken" for a split second before they appear, as if it is having a hard time pulling them from a remote server. Other browsers don't do this. What could be causing Firefox to hang when searching Google?
