  • To Run Linux (Ubuntu) on Windows 7, is using Virtual PC one of the best ways?

    - by Jian Lin
    I need to try Linux (Ubuntu) and feel hesitant to install Ubuntu on top of a Win 7 machine to dual boot (might need to use Win7 and Ubuntu at the same time). Is creating a Virtual PC on Win7, and then installing the latest Ubuntu on that Virtual PC one of the better option? So I think I can create a Virtual PC with an empty virtual hard disk (vhd), say, for 30GB, and then put in the Ubuntu DVD-R or CD-R to install Ubuntu onto that empty hard disk. Update: for some reason, the first time Ubuntu 10.04 installation CD-R boots up, it asked for the Language, and "Install Ubuntu" and then the screen has vertical green bars and then the VPC just closed. The 2nd or 3rd time it booted up, there is no asking of Language or "Install Ubuntu" and just shut down the VPC, sometimes with vertical green bars. I even created another new hard drive and same thing happened. And created VPC 02, and same thing happened. Created VPC 03 with a fixed hard drive size of 60GB and same thing happened.

  • Does Chrome use a different DNS server while Firefox and IE use a different one?

    - by Jian Lin
    Is the common set up for Chrome that it will use a different DNS server, while Firefox and IE will use a different one? My Chrome (including the one on the virtual PC) will sometimes "Resolving host" and wait there for 20, 30 seconds, while Firefox and IE won't. (so after 20, 30 seconds with a blank page, the page will finally not be able to load). So is there something that Chrome is doing that make the difference?

  • Windows 8 Secureboot: How do you bootup from another device such as cd/dvd drive or usb flash etc.?

    - by Victor T.
    On PC's and laptops running an older OS, this is just a simple matter of going into the BIOS and setting the boot sequence and putting the boot cd/dvd in the drive. In many cases you can even just hit one of the F* function keys to bring up the boot sequence menu on-the-fly during POST. The main problem I'm running into is that other devices besides the primary HD is disabled when SecureBoot is enabled. So far the only way I've gotten it to work is to disable SecureBoot and enable something called legacy mode. Needless to say this make it difficult to boot things like OS recovery tools, PartitionHD backups, Linux LiveCD's and a bunch of others. Is there another procedure for doing this since it seems to mess up the Windows 8 install? By mess up I mean that after re-enabling SecureBoot and starting Windows 8 normally, the OS goes into a 'preping repair phase' for some reason that takes forever to complete before getting into a usable desktop.

  • On Windows 7, how to Shut Down the computer without the Update?

    - by Jian Lin
    Sometimes when my Win 7 machine has programs that crashed, maybe Firefox, or IE, I would like to shut down the computer without installing any Windows update. That's because I worry that if IE or Firefox crashed, the system is not in a very stable state, so I would rather install the update later. But it seems I only have 2 choices: 1) Shut Down and it always will do any Update 2) Restart, and no update is done (these are 2 choices among the shut down / log off option) So is there a way to Shut Down without doing the Update? Or must I restart first, and then do the Updates, and then Shut Down?

  • Cannot delete movie on iTunes for iPhone 4?

    - by Jian Lin
    I was on vacation and took some videos, and now the iPhone 4 memory is near full. So I tried to delete other experimental movies I made using Handbrake, so that I can take more video or photos, but if I plug the iPhone 4 into my Notebook computer, I can seem to delete it on iTunes? Maybe because the computer I sync with the iPhone 4 is at home (a desktop), but not with me on vacation. I can't delete it on iTunes, can't delete it on iPhone itself. I am stuck during the vacation, or is there a way to handle it?

  • Full Apache config migration

    - by Victor Rashkov
    I searched alot and didn't find an applicable answer. I have a working LAMP setup on Ubuntu machine and I have to migrate to a new server in a different country. The old server is 11.10, the new server is 12.04LTS. My problem is that I simply can not remember the steps I followed when I configured the current server which is not the basic LAMP install. It is Apache with FastCGI, SuEXEC, a GD library, worker MPM and all sitting on top of a mhddfs system. There are also other configs I've changed and I can not recall what they are. Because of the complexity of the setup, my attempts to migrate to the new server fail. I get permissions errors, cgi problems etc. Therefore my question is : Is there a sane way to simply tar a full backup of the current web server installation, including MySQL, Php amd the apache server with all configs, and then move it to the new machine? I shall be forever thankful on any advise. So far non of thise I found here gave me an answer. Thanks!

  • Virtual PC on Windows 7 doesn't have adjustment for video card size?

    - by Jian Lin
    The current VirtualBox has a place where the video card size can be set by the user. It seems that Win 7's Virtual PC doesn't have one? Will it auto adjust -- but what if the screen size is 800 x 600 and the user resize it to 1600 x 1200, then the original video size may not be enough and will that cause any issue? I do sometimes see blinking random pixel region showing on the VPC's screen... maybe it is cause by not enough video RAM size?

  • Seagate 3TB hard drive loses format information

    - by Victor Bugarin
    I have a Windows 7x64 Ultimate, 6 GB memory, 1 TB HD. 3TB Barracuda XT HDD. The HDD is installed on a StarTech 4 bays external enclosure I had troubles so I converted to a GPT, created 1 partition and formatted as NTFS. The hard drive I can write and read to and from the hard drive but it will become unreadable at some point while I am copying files or after I have copied files to it. I have copied large Bluray movies and diverse video files, I have also copied 32 GB of pictures, and I have copied about 86 thousand music files in different formats. At some point the partition becomes unreadable and I have to format the partition again (all files lost) and I have to start the whole process again. At some point I have been unable to copy large ISO (Bluray movies) file images. I have partitioned the HDD in 2 partitions P1 - 2TB, P2 - 1TB and I have lost every single file in either partition the same way. I reformat the HDD and it seems fine. I have run seatools to check the hard drive and it reports to be OK. What gives?

  • Any method to resize my app's window on Mac (macbook) to 1600 x 1200 or 1920 x 1200?

    - by Jian Lin
    I would like to make a screen capture for an app (Firefox), but I am using a macbook, so the display is at 1280 x 800. I think if I can somehow resize the window to 1920 x 1200, then I can use Command + Shift + 4 and then space bar, and then mouse click on that app to capture the whole app's window (which will be bigger than the screen) So I can resize the window horizontally to 1920 by dragging the window to the left, and then make it wider by going to the bottom-right corner of the window. But there seems to be no way to make it taller... even javascript: self.resizeTo(screen.availWidth+300,screen.availHeight+300); on the Firefox address bar (URL bar) won't work... it can make the window wider than the screen, but not taller. Is there any method at all?

  • How to solve the problem that Chrome doesn't obey "Show Window side by side" on Win7?

    - by Jian Lin
    If I bring out Firefox and Chrome, and right click on the task bar and choose "Show Windows side by side", Chrome will not be arranged side by side. But if it is Firefox and IE, then the 2 windows will in fact be arranged side by side. If it is Chrome showing and we press and hold "Window key" and LEFT ARROW, then in fact it does move to the left as a half size window. So Chrome partially work on Win7 for the expected behavior. Any method to make it work for the first case? thanks.

  • Can most Intel processors run 64-bit Windows 7?

    - by Jian Lin
    Can most Intel processors run 64-bit Windows 7? Such as all the i7, i5, Core 2 Duo, Dual Core, Single Core with HT, and even just Single Core? I think a popular view is that if you can run 64-bit Windows 7, then use it? It might have driver compatibility issue but if there is no device hooked up, then there is no problem? What about some software / games not compatible with the 64-bit version or may run slower? thanks. update: a couple of my machines have 4GB RAM. so 64-bit Win 7 can make use of the full 4GB RAM instead of only about 3.2GB

  • Are Uninterruptible Power Supply (UPS) at home really a worthwhile investment for home computing? [c

    - by Jian Lin
    Possible Duplicate: Is a UPS a good investment for a home machine? I have 2 Uninterruptible power supplies at home, but they seem to expire after 5 years or so. During this 5 years, it maybe saved the computer from turning off twice. But I wonder, I often save my documents every 10 minutes. So the most I can lose is 10 minute worth of work. Not to mention that, I may not be editing anything when the power is out. Also, when the UPS expires, one of them will give out beeping sound once in a while, probably signaling the changing of the battery. So I can either buy 2 new UPS or just buy 2 power outlets instead. 2 UPS, costing $160 to $250 roughly, can it be really worth it if it can save your computer from powering off for just 2 times? What are the alternatives?
