I don't speak Arabic (or whatever language your blog is in) but I thought it looked OK. The translated (by Google) version was a bit rubbish, as it translates literally. If you can find a way of translating into English which would be better, you could add a link to choose the English version. There is a way - I just can't remember what it is!
The only thing I'd criticise is the greeting bit about the peace of God - this may be an Arabic version of 'hi there', but in translation, it's a religious phrase which is inappropriate considering your topic is computers, not religion. It's like saying, 'May God bless you all - now, about Windows 8.1...'
Also, you might consider having a phrase which describes your site on your home page, e.g. 'Cool computer tips for professionals' or 'Get the most from your internet business' or whatever.
