encryption - Is it safe to open a crypted file with a text editor -


say have files encrypted , open them text editor, in risk of files being copied in temp memory ? noticed sentence in introduction on truecrypt website

"note truecrypt never saves decrypted data disk – stores them temporarily in ram (memory). when volume mounted, data stored in volume still encrypted"

but understand correctly ?

if file stored in truecrypt volume opened in text editor (or application really), decrypted file temporarily stored in ram. once in ram, application potentially copy data if can locate files contents in memory. feasibility of highly dependent on operating system you're using though.

also, editor you've opened decrypted file in may save copy of non-encrypted disk. once you've opened file in application can wants data, doesn't matter data came or in form stored.

last, depending on operating system, os may leave traces of encrypted files. example, windows keeps list of opened files, , while doesn't leave decrypted file contents lying around, reveal names of files truecrypt volume opened.

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
