I become a panda, an elephant and a blogger

as a part of change every time there is an exam coming for me I promise myself to start studying like a first class student and finish everything up the night before exam and go rock it, but my 23 years life experience shown that I can never achieve that in the frame I want it to happen, when there is an exam coming I start loving to sleep and feeling tired the whole day, I start feeling hungry everytime I open my slides and I also start feeling like posting something on my blog like a pro-blogger. damn it, I should straight my mind and get back to that Artificial Intelligence subject. it’s a killer task to memorize all those stuff about expert systems, robots and history of them.

wish me luck people!

why multiple updates appear at the same time on Google Play?

It always was a question for me that why application updates on android phones comes together in bulk? it has been like this for me ever since I started using android on my HTC ChaCha. Suddenly Google play shows the notification that some updates for some apps are available, but it never happens for 1 app only, atleast 3 app are involved in each Play Store update notification.

Have you faced the same thing? do you know the reason? if you do then leave a comment so me and other users may know too!  icon smile why multiple updates appear at the same time on Google Play?

So Yahoo keep asks me to change my Password

The recent issues I’m having with my Yahoo id is annoys me somehow, since last 1 month I have been asked by Yahoo team on my other email address to attempt for changing my Password as they say it’s a security matter for them as my account might be in danger due to the security incident that happened to them.

This is the 4th time I’m forced to change my password after receiving this “Your Yahoo Account” subjected email with following content:

Hi Mahdi,

The safety of your Yahoo account, mahdi.hazaveh, is important.

We’re asking users to change their passwords due to recent security incidents online. While Yahoo systems were not affected, we may take extra precaution and lock user accounts when we detect unusual activity.

Please sign in to Yahoo and change your password.

But in some points I feel this is happening when I’m using 3rd party IM client apps to use my Yahoo account like IM+ and Pidgin.

Well as long as I can remember what I’m choosing for my new Yahoo password I think i can bear with it until this issue comes to an end.

How many of you have trashed your unpublished posts within 5 minutes.

well yeah that happens to all of us when we are posting something in Facebook, Twitter or other social networks that we remove and rewrite our status multiple time before posting it online, but how about the blogs. It has happened to me alot while I was talking about some subject in a 500 words article and I am sure I was certain about posting it, but all of sudden I change my mind and I totally trash it. I’m not talking about editing it and reposting it in another way, I just delete it like it never existed! Well that’s a fact it happens because I decide not to post it anymore but why does it take me to write it all down then only find out I’m giving it up, and I don’t want to talk about it! that somehow feels like getting close to someone you having a crush on then suddenly you skip the talk and forget it away! is that called as self-censoring? or maybe self-awareness of how stupid the topic I was writing about was!

I’m not sure about the answer for this one yet.
