Enjoyed it? Which one felt odd? The first one? The second one?

Now the crux of the matter. Which do you think was written by an AI (Artificial Intelligence) ?

Hi there! Have some new code based on Matlab. It was actually a Computer Exercise for my Telecom course. It is an example of Amplitude Modulation of a Cos based message. The code is easy enough. If you have any questions please ask. Hope you enjoy it.

I had a revelation on love last week. I must say it opened my eyes and certainly made me think on the feeling of love. I won’t go into the deep details of the meaning of love and it’s effect on theology, sociology or economy(Valentine’s day man…). But I would rather would like to sum up the whole thing.

Love is tender. Love is warm. Love is soothing like; when you have this sore tooth and you put a cool stone on it to alleviate the pain and the hard truths of life. Love comforts. Makes you forget. Love has it’s own time. Some will last for a mere second while others will live on throughout the ages. Love remembers. Love leaves its mark. Like a small scratch on a glass. No matter how you try to wipe it away it is there to stay.  And love can be wounded. It could be hurt. However love can also heal. So never loose hope.

There… My two cents on love.

Apple made a new product called iPad. Like their iPod and other iPod related items they expect the consumers to consume this product. However it seems iPad has done couple things wrong and is soon going to meet up with a wall. The walls name is Google Chrome OS tablets.

iPad does not have any USB ports hence the only portability you will be getting is from the other connections like Wi-Fi, 3G, Bluetooth and SIM card tray… But you won’t get your USB. Now some will argue why you would need a USB input here are a few examples; 1. USB keyboard 2.USB mouse 3.USB data stick 4.USB external harddrive 5.USB video cam etc etc etc…. As you can see USB would have added many more functionalities to a simple over sized iPhone.

Another point why users won’t (and/or isn’t) dying to get an iPad is it’s marvelous screen. While many iCandy users will enjoy reading their long 365 page pdf’s on, a 9.7-inch (diagonal) LED-backlit glossy widescreen, Multi-Touch display with IPS technology 1024-by-768-pixel resolution at 132 pixels per inch (ppi) Fingerprint-resistant oleophobic coating 9.7-inch (diagonal) LED-backlit glossy widescreen Multi-Touch display with IPS technology1024-by-768-pixel resolution at 132 pixels per inch (ppi) and its fingerprint-resistant oleophobic coating display… while some other people would rather read their pdf’s on a simple Kindle or another generic e-ink display… You see most power users (a big market that bought the iPod and the iPhone) already have a tablet. And a e-reader. Why should they bother to pay more for less?

And of course there is the wall where iPad will soon be colliding. Whether this train of Apple iEmpire will pass through it like a it was a hay stack or stops for good depends on GoogleChromeTablet pc.

Google has be feverishly working on a new operating system called Google Chrome OS they say that the first computers to use the Google Chrome Os will be the net-books. These light portables are ideal for Google Chrome OS since basically it works on this idea; everything will work in the “internet-cloud”.

Google has also has also announced that this OS will also work in PC’s and there goes a punch to both Microsoft AND Apple. Google is entering the OS market. And it is making big promises which developers and users around the world hope they will keep.

Google has already started posting design examples on their web site. One of them is this short video I stole from them.

I hope you enjoyed this post… Won’t get iPad even if it was free… Sorry…

It seems blogger.com is closing down it’s FTP service. Good thing I already transferred my site to WordPress before hand.

My blogging life has been quite the roamer. It seems I like my individuality. My road started with LiveJournal.com. One day I opened my LiveJournal account to find it blocked by the firewall of our school. Some people used to put their nude pictures on their LiveJournal so it was banned.  I got angry at this. Thus I transferred everything to Blogger.com. But guess what! Turkey blocked Blogger for about four to five months this got me mad. So what I did was make Blogger.com send the info to my FTP host. I even bought a domain for this host. A little coding and voila! My was site was back up and running. However this got me thinking. What if Blogger was totally banned? What would I do than? Hence I started looking for blogging scripts and that is how I met WordPress. I must say I’m very happy with it. I even integrated Zemanta with my browser to bring in even better content. In fact the picture here was found thanks to Zemanta. Anyhow…

So Blogger is closing down it’s FTP service. So what. It seems Blogger is thinking the same way. The mail they sent me states :

FTP remains a significant drain on our ability to improve Blogger: only .5% of active blogs are published via FTP — yet the percentage of our engineering resources devoted to supporting FTP vastly exceeds that.

It seems Blogger started cutting out the rotting flesh. The hoards of zombies that try to live on old tech. And this also shows Google’s business management. If it doesn’t work, cut it out. Which I believe is one of the best ways to do management. Look at HP Labs present condition. Actually look at any big corporation. The only way you can go big is use this kind of thinking. I know… I know… It probably meant that the current FTP “engineering resources” our out of a job. But still… The show must go on.

Oh and for the people asking, the snow effect will still be here for a while. It is still snowing in Ankara, Turkey.
