The meth of ebay buyer protection

It is just a meth, they get there money from the sellers, so they will always try to keep good contact with them and keep them happy. SELLERS on ebay LIE all the time (except for some of them). I had many cases on ebay that the item was totally not as described, and these cases were in both under ebay buyer protection and not. The best case scenario is that you will return the item to the seller (and you will pay for the shipping) mm. 

   and you will have either a full refund of the original amount + the original shipping, or only the original amount without shipping. So the BUYER always looses and the SELLER go away with it.  In other cases of course you will get nothing, and they will either tell you sorry the item is not covered by ebay buyer protection or the seller doesn't have a return policy. So any one can lie as he wants on ebay as long as he doesn't offer paypal as a payment method. Of course ebay is happy with these people because they make the buyers scared and make them try to buy in paypal where the profit increases for ebay (they get the commission doubled now) . In a case a seller was offering a laptop where he used multi time technical details about an item, i.e. one time he wrote the laptop has a hard disk of 80 GB and in fine line some where else he wrote no hard disk, also, in another place he wrote that the laptop has a processor of 2.4 GHz and in another place 2.2. Usually when you find in a description that the HD is 80 GB, you don't look about other details about the HD. This is pure scam, but ebay allowed it and even deleted the negative feedback i gave to the seller when the seller agreed to return the item, of course i lost the cost of the shipping both ways although ebay stated in the resolution center in the case that i opened that he will return the original amount + shipping. but at the end they get the money from the seller so he doesn't need to loose anything. even if it is clear that he is a scammer. In any case ebay has many honest sellers and i hope for everyone not to need to deal with ebay themselves as in ebay there is 2 customers the seller and the buyer, and the buyer always comes the  second.

Displaying double quotes in Latex

i always thought that we can display all kinds of special characters by using the escape symbol before them like that \" , but the quotes has different requirements
you have to use ´´ for left quotes and two single quotes ' ' for right quotes.

Extract animated gif from MS Powerpoint for mac

You may all have noticed by now that the save as web page is not an option on Power point for mac 2011, so there is no easy way to extract animated Gifs from power point presentations, one way is to add .Zip after .pptx at the end of the file then open it as a zip file, you will find a lot of folders, you will find the images in a folder named media, do some search till you find the needed file, and thats it :)

Convert character set to utf8 in MySQL

Say, you had a MySQL database that stores texts in languages such as Chinese, Japanese, Korean, Hebrew, Arabic, and so on, and recently there was a server move or upgrade, and all of sudden text in the above mentioned languages didn’t display properly. What do we do to fix it then?

Latex::Wrong figure numbering and in figure citation

I had a problem when i was preparing a journal of mine, that made me nearly crush my mac, some figures were referenced wrongly in roman letters , no matter what i do. after a long search on the internet, i found that this sort of error has one of two sources (and for my luck, i had them both :) )
1- For some reason you can't put \cite or \ref commands inside caption \protect\ref{fig:xxx} or \protect\cite{xxx}.
2- The other thing is you have to put \caption , \label , \end{center} , in the same mentioned order :) , sometimes it work if you use different order, but for my case it didn't ...

and thats it
