    My First and Last 3D SketchUp 

    So, here is the first one.

    This slideshow requires JavaScript.

    I had created this long back in Decemeber of 2006. The file cab.skp (Google SketchUp file) was lying in my system since ages. Tried opening it today, discovered there is no Linux support for its viewer/editor (you listening Google?). After some fiddling with Wine and finally resorting to spend some time on a friend’s Windows Laptop, here we are. Quite a piece of art, ain’t it? 😉

    Title: Zebronics GeForce Case 2

    Description: The glowing big-forehead alien cabinet of my PlatiniumV2.

    If somebody is interested, I found a review of the cabinet.

    Restore GRUB in Ubuntu after installing Windows 

    So, you had Ubuntu (or any of its derivative) installed on your system and then decided to install Windowswith it? And after installing Windows, you can’t load Ubuntu again, just follow the steps to get this working:

    1. Boot the system using a Ubuntu Live disk.
    2. After you reach the desktop, open Terminal (press Alt+F2, type “gnome-terminal” without quotes and press enter).
    3. Execute:
      sudo fdisk -l
    4. Execute (after replacing sda7 with your corresponding linux root partition, which you will be able to identify from the output of the previous command – it’s usually marked as Linux):
      sudo mount /dev/sda7 /mnt
    5. Just check whether you got the root partition right, if you have more than 1 linux partition on your hard disk:
      cd /mnt
      ls

      If the listing contains names like bin, boot, dev, etc, home, tmp, usr, var, et cetera then you are in the right partition. If not, unmount this using:

      sudo umount /mnt

      and follow the above step again using another partition.

    6. Now:
      sudo grub-install --root-directory=/mnt /dev/sda

      and grub will get installed if it shows no errors.

    7. As a last step unmount your /mnt directory using:
      sudo umount /mnt

      and restart the system. You will find the friendly grub boot manager giving you the choice to boot into Linux or Windows.

    Sharing Internet Connection from my Laptop to my Android-based Phone 

    I was disheartened to know that my newly bought Samsung Galaxy S i9000 could not connect to an ad-hoc network created from my laptop.

    After a little Googling, I found out the easiest way to turn a laptop into a WiFi Hot Spot (for uses such as sharing Internet connection with my Android phone) – Virtual Router and now I am enjoying fast internet on my phone.

    As I call the above the easiest, it’s not the best method and doesn’t offer much features either. If your needs are not satisfied you can look for Connectify – the inspiration behind Virtual Router.

    I forgot to mention that both of these methods work for windows, I still have to figure out a way to do the same under Linux.

    EDIT (2012-04-28): Okay, it’s been too long, frankly because I was not using Linux much all this while (thanks to my laptop which used to turn into a heater with almost all distros I tried), but finally I found a way to share net from Linux too. I am on Android 2.3.6 XXJW4 on my SGS i9000. The following steps should work well with all versions of gingerbread:

    • Root your Android. Folks at Android Advices usually come out with the easiest possible tutorials for things like this, I followed the steps available here, YMMY.
    • Take a backup of your current /system/bin/wpa_supplicant file using a root-enabled file manager (Root Manager is a good option, though not available for gratis)
    • Download the latest version of AdHoc fix available at this thread at XDA Forums, and transfer it your phone’s sdcard.
    • Either apply the fix using by booting into recovery or just extract wpa_supplicant file from the zip and overwrite it at /system/bin using your favorite root-enabled file manager.
    • Create a new ad hoc network in your linux system, and voilà you will magically find it when your phone scans for wi-fi networks.

      I tried both, but when using Connectify, the galaxy s and computer connects but the internet doesn’t work on the phone.
      And when i used Virtual Router, it automatically stops in a while

      Please help

        What are the versions of windows on your system and android on your phone? I am unable to reproduce your problem.

        By automatic stop do you mean the phone drops the wifi connection or the net simply stops working?

      How you did this. Please tell me the steps you followed.
      Thanks

        I just installed Virtual Router, shared the ethernet connection. Then on the phone the connection was visible after enabling wi-fi, and voila it connected. 🙂

        Sorry, I personally prefer using Virtual Router, and don’t have much experience with Connectify. Please try switching to VR or see the help on Connectify’s website.

      not work in android 4.0.4

        You forgot to mention which method – windows/linux?

        As mentioned within the post, the methods work for Gingerbread. I am yet to try these out with ICS, will update as soon as I get time.

      The wpa_supplicant provided does NOT work for JellyBean (galaxy nexus)…

        Agreed. It doesn’t. Are you aware of any alternative for JB?
