MacBook Air 2013 Ubuntu Suspend Mode Issue

I had been a while using ubuntu on my macbook air with the suspend issue. Usually, I will just use the hibernate mode. Is good to just flip up and use the system but the suspend mode keeps on turning off my screen brightness. Never ever able to get it work until today I googled around and got it work with this link: https://help.ubuntu.com/community/MacBookAir6-2/Saucy#Suspend.2BAC8-resume_backlight_issue

1. Install the package:

wget http://miek.nl/downloads/2013/mba6xbl-dkms_0.0.1_all.deb
sudo dpkg -i mba6xbl-dkms_0.0.1_all.deb

2. If /etc/X11/xorg.conf not exists, create it:

Section “Device”
Identifier “Intel Graphics”
Driver “intel”
Option “Backlight” “mba6x_backlight”
EndSection

3. Making sure mba6x_bl auto started

sudo echo “mba6x_bl” >> /etc/modules

4. Reboot the laptop and start trying out the suspend mode.

I am pretty excited and happy over this now ;)

BASH is Vulnerability

Recently I had read some news letter from my emails and shock to see that BASH is Vulnerable. For all my servers as I am using only Debian, I just apt-get update && apt-get install bash and all my bash are updated easily.

To check the vulnerability:

env VAR='() { :;}; echo Bash NEED update!‘ bash -c “echo Bash Check”

If the returns:
Bash NEED update!
Bash Check

Then the server/client pc will need to update to the latest version of the bash.

Raspberry Pi SDCard Modification

IMG_20140901_003958IMG_20140901_004011
There is a broken SDcard 4GB Imation lying on my place for quite some time. Actually, it was only the housing for the SDcard is broken.

What I had done was getting an unused microsd converter and dismantling it then put in this sdcard chip into it. Slowly file the edges inside the housing and placing the chip in.

Next it to make sure the micro switch still there to allow the read/write enable. Once I confirmed everything works, I dumped the raspbian image into the SDcard and cut off the rest of the unused section. The above images are the final output of what I had done to it. Happy to revive this sdcard as it was never used before after purchasing it. The housing broken due to the high temperature and the plastic cracks then broken.

Hope this help to other people, never throw away the broken things. Revive it.

Raspberry Pi – SDCard Corrupt Issue

RaspberryPiB256

Have you ever faced some SDCard corrupted after each reboot? Well, recently I had accidentally broken the capacitor from the board and never thought that it so important to stabilized the voltage in order not to corrupt the sdcard.

It was random and also depending on sdcard. Some SDcard works fine but some not. I suspected my SDcard at first. After I switched to another Raspberry Pi, it works great with the faulty SDcard. This proves that it must be the board and till I compared then I noticed that the capacitor was torn off from the board. I quickly took some old capacitor from my junk and replaced the missing capacitor.

The thing works great and I had keep rebooting it without any SDcard corrupt any more. So, guys out there, please remember the capacitor is important and also need a stable voltage supply to this board in order to keep it working.

Nexus 5: GPS issue

After my little girl dropped my phone, I am facing some minor GPS signal lost. After googling around and found that seems quite a common issue. Well, it actually just need to open up the back cover and just slide a since paper and lift up the connectors so that it can have 100% connection. Well, it does work and my GPS  sensitivity gain back with the accuracy of 10M.

Thanks to Google again for leading me a good reference and fixed my Google nexus 5.

HomePlug Mixing Is Possible

aztech

tplink

I have many homeplugs around my house. Initially, I was using TP-Link and due to I am expanding my infra of my current setup and need more bandwidth plus stability (also have a friend of mine donated to me lots of Aztech) and ended up using only Aztech. Till today, I got a wild idea where combine all types of Homeplugs. Reason is because I am also testing my SDR GPS over another room where I can get FULL GPS signals there but unfortunately without any LAN connection. So, this idea comes out of the blue and it works.

It just need to sync up and that’s it. So, as a result, mixing homeplug with different brands is plausible.

Hope this information helps everyone.
