Nokia e71 vs iPhone first hand review

Sun, 01/18/2009 - 15:26 — shoaib

Well, its day 2 - I went one step ahead and bought myself nokia e71. Gota tell you. It beats iPhone hands down!

In every bloody aspect!

nokia e71

It's got some really neat features that it doesn't even mention on the box! or even any review that I've read so far.

Here are a few that I havn't seen any other review mentioned.

It plays flash! Youtube works like better then iPhone. It has a wider screen then iPhone. It doesn't even just play flash. It even plays real media, mp4, mpeg2, xvid!

You switch between modes like if you are at work you dont have any thing to do with multimedia then it can go in to business mode and also connect to the appropriate wireless access point in that "mode".

I've seen reviews say that "it doesn't have a 3.5 mm audio jack" but they don't say that its got a 2.5mm jack which can be easily adapted to 3.5!

It actually is lighter then iPhone.

Looking in to Thermochromism

While I was reading up on this interesting topic of Thermochromism http://en.wikipedia.org/wiki/Thermochromism. I ran in to some cool projects. These are quite old technologies but yet new to me. Thought I might share.

I can see how this can be so useful for law enforcement agencies and traffic wardens or business to promote their product.

The next technology is heat sensitive fabric that changes color. Also known as Hypercolor t-shirts. These are commercially available and surprisingly enough quite cheap too. I am planning to buy one :D

Disk usage/statistics and clean up in linux shell

Sat, 01/10/2009 - 10:06 — shoaib

Came across article so, thought I might document it here as well.

As I always struggled in command line to work out disk quota, usage and other statistical means of working out what could be using the disk. Apart from df -hl, I was unable to work out directory sizes and order them and so on. Just like you would be able to in a graphical user interface.

So, here are some commands and tools to assist in that process.

Quoted from linux.com article :

The CLI way

The df utility displays the disk space usage on all mounted filesystems. The -T option prints the filesystem type as well. By default, df measures the size in 1K blocks, which could be a little difficult for a desktop user to decipher. Use the -h option to get more understandable output:


$ df -h -T
Filesystem Type Size Used Avail Use% Mounted on
/dev/hda6 ext3 20G 9.3G 9.1G 51% /
/dev/hda7 reiserfs 13G 2.1G 11G 17% /mnt/suse
/dev/sda1 vfat 241M 152M 90M 63% /media/usbdisk

Car Audio Revisited

Fri, 01/02/2009 - 01:29 — shoaib

Today, I completed my set of car audio. Following is the implemented sound in my car.

Everything now runs via 9 Band parametric graphic equalizer for optimum sound! Using two amplifiers, one for 4 channel speakers rear and front. The other Sony 125 WRMS amplifier to power the mid-range compnent speakers in the rear (boot).
