You can make your own Wireless Access Point with Raspberry Pi using Tenda Wireless USB Adapter (W311U+).    It won’t give you the same performance like the commercial one… but it will allow you to connect at least 5 devices and install network security packages to play with 🙂  neat!

Bought from Octagon Megamall with PhP600 price tag.  You can also try other Wireless USB adapters like CDR-King’s… but check if it can operate on “Software AP” mode.

Hello Ubuntu 12.10!!

image

Upgraded from 12.04 to 12.10 on Samsung Ultrabook Series 5. Can’t make my touchpad work… still fixing huhuhu

Update: I was able to make it work by doing these:


$ cd /usr/src/
$ sudo wget http://planet76.com/drivers/elantech/psmouse-elantech-v6.tar.bz2
$ sudo tar jxvf psmouse-elantech-v6.tar.bz2
$ sudo dkms add -m psmouse -v elantech-v6
$ sudo dkms build -m psmouse -v elantech-v6
$ sudo dkms install -m psmouse -v elantech-v6

My touchpad works after that. I followed the instructions from here but after updating the kernel to 3.6 and rebooting, my webcam and wireless doesnt work. So I load up the previous 3.5 kernel.

You will notice that on the system settings, the “touchpad” is grayed out. You have to install:

$ sudo apt-get install xserver-xorg-core

… then multi-touch and touchpad settings will be back and working.

Ubuntu 12.04 missing system hibernate?

I upgraded my Lenovo 3000 V200 Ubuntu 11.10 to 12.04 just recently. And I noticed that my favorite “hibernate” is missing.  So… I read and modified the kernel sources.. recompiled…… JUST KIDDING!!!   I actually googled and found this thread (http://askubuntu.com/questions/94754/how-to-modify-policykit-to-allow-hibernation-in-upower) and it works!!

Just create or modify this file using your favorite file editor (vim works for me!)

/etc/polkit-1/localauthority/50-local.d/com.ubuntu.desktop.pkla

And put…


[Re-enable hibernate by default]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes

A restart (power cycle) to apply the changes and then wooolaaa!!! “hibernate” is back!!

I installed Ubuntu to my Lenovo 3000 V200. Everything works until I found out that my headphone jack is not working.  I tried googling the fix that leads me to this link:

GNU/Linux IDE : From Kate to Geany

I was using KATE ever since… but now I’m using Geany instead. Try nyo nalang kung bakit…

This is not a blog saying who’s the best editor in town… It might be EMACS… it might be VI… ok?

Geany is a small and lightweight Integrated Development Environment. It was developed to provide a small and fast IDE, which has only a few dependencies from other packages. Another goal was to be as independent as possible from a special Desktop Environment like KDE or GNOME – Geany only requires the GTK2 runtime libraries.
Some basic features of Geany:

  • Syntax highlighting
  • Code folding
  • Symbol name auto-completion
  • Construct completion/snippets
  • Auto-closing of XML and HTML tags
  • Call tips
  • Many supported filetypes including C, Java, PHP, HTML, Python, Perl, Pascal (full list)
  • Symbol lists
  • Code navigation
  • Build system to compile and execute your code
  • Simple project management
  • Plugin interface (see Plugins)

Geany is known to run under Linux, FreeBSD, NetBSD, OpenBSD, MacOS X, AIX v5.3, Solaris Express and Windows. More generally, it should run on every platform, which is supported by the GTK libraries. Only the Windows port of Geany is missing some features.
The code is licensed under the terms of the GNU General Public Licence.
