Asus EeePC 4G Surf revival

Update: Consider running the x86 port of Android 4.0 (Ice Cream Sandwich) on your Asus EeePC 4G Surf. Download the android-x86-4.0-RC2-eeepc.iso here and follow the instructions for installation.You won't believe how slick it will make your old EeePC!

I recently dug out my old EeePC from the back of my closet and tweaked it to better than new. The improvement is mostly thanks to a fresh installation of Zorin-OS 7 lite which I think is a totally awesome Linux distro for this netbook. It's a shame that Asus didn't use something more like Zorin-OS with the initial 2007 release of the EeePC, but it's only been around since 2009. I never imagined I could be running Chrome 28 on my EeePC and I easily re-installed Frozen Bubble and Extreme Tux Racer from the Ubuntu repositories - It's so much easier to install software  than it was using Xandros and everything is up to date!

During my investigations into upgrading the OS, I also came across suggestions that the EeePC uses standard laptop RAM (DDR2), this was a nice find as I had a spare 1GB DDR2 laptop module lying around. It was no mean feat to get to the RAM slot as the white version of the EeePC doesn't have a door underneath (apparently the black one does). I'm not going to document the full process (you can watch a video here), but I can confirm that if you carefully dismantle a white 4G Surf, you will find a standard laptop RAM slot on the back side of the motherboard. It was worth the effort as my 1GB module is working great and more RAM is always better!

I deleted all the factory drive partitions during installation (from a USB stick) and assigned the full internal 4GB drive to Zorin-OS. In the spirit of putting redundant hardware to work I slapped in an old 1GB SD card as well and set this up as the swap partition. I've got a full 1.3GB of free space on my 4G now which I didn't even dream of previously and while the 4G Surf remains well past its use by date I think I have actually made mine fairly useful again.

Send 20 free Vodacom SMS from your smartphone

If you have a smartphone on the Vodacom network then you have 2 options to send 20 free SMS (to other Vodacom numbers) per day.

1. The easiest option is to just install the My Vodacom App (available in the App Store / Google Play / BlackBerry World) and login using your Vodacom website details to send Free SMS.

2. You can also access the desktop version of the Vodacom website from a smartphone. Just head over to vodacom.co.za on your phone (this will load the mobile version), scroll right down to the bottom of the page and select the 'Switch to the full site' option or click the direct link here: http://www.vodacom.co.za/personal/RedirectFullSite - This link will load the desktop version of the Vodacom website on your phone and you can login to send free SMS.

The full desktop site may work on some feature phones, but I think it requires a browser that supports JavaScript in order to work properly which is not a standard feature on all phone browsers (sorry, you can't login using Opera Mini). If you are using Opera Mini or some other feature phone browser then you should be able to send free SMS to South African numbers from free082sms.co.za

Twitter phishing - Don't take the bait!

In the same way that scammers use phishing emails to try and snag your banking details, they also use direct messages as bait to try and catch your Twitter account login details. If they are successful, they will use your Twitter account to send the next batch of malicious direct messages to all your followers and so the cycle perpetuates...

I have almost 7000 followers on Twitter (@mobidk) at the time of writing and my DM inbox is overflowing with these scam messages to the point that I flat out ignore direct message notifications, in fact I wish I could disable my DM inbox entirely. Short of that I'm hoping that if people get educated, then fewer will need to learn about Twitter phishing the hard way.

Here's a snapshot of my Twitter DM inbox for you to get a feel of what one of these scam/phishing direct messages look like (I've concealed hacked users' identities)

How to identify a spam / scam / phishing direct message on Twitter
  1. It will contain a link
  2. It may contain poor grammar or spelling (whos versus who's)
  3. It will most likely be arbitrary and seem to come out of the blue (from someone who doesn't often direct message you)
  4. Typical themes center around gossip related to you (people saying nasty things about you, or a funny picture of you, or who's been viewing your profile etc)
Be suspicious of any messages that match any of the above points, but the best rule of thumb is to never click any links that you receive by direct message. Typically the link will bring up a fake Twitter login page, prompting you to login and this is how the bad guys get your details. Most good Anti-Virus can block these Twitter phishing login pages and warn you though, so it's important to run an Anti-Virus and keep it up to date as another layer of protection.

If you really are dying to click the link or you aren't 100% sure that it is a safe message, then message your friend back and ask them if they sent you the message intentionally before you click! It's not a bad idea to reply to the sender anyway and let them know that their account has been compromised, though Twitter will most probably reset their password for them. Otherwise, you can send them to this link that explains what to do if your Twitter account is compromised.

For what it's worth, I have also seen similar messages used to spread malware on the Skype IM network and Facebook, so be aware! These tactics are used across many social media channels.

p.s. I used the handy tool over at www.dmcleaner.com to delete all the DMs in my inbox in one foul swoop... (Though technically it was a few swoops as it deletes in batches of about 150 DMs per batch).
