Pycharm-3.4.1 is installed and activated successfully under Ubuntu4. future development in Ubuntu environmentPreparatory work:1. convert path to native /devstack/2. turn on vagrantand enter the command:Vagrantup3. using ssh connection vagrant, enter the command:Vagrantssh4. give the edxapp account A password, enter the command:SU

Open Online education platform EdX opened in June this year, when the Google group method "clean install on Ubuntu Server 12.04" in a brand new VPS installed A, although the final installation was successful, but also spent some trouble, Finally, the overall impression of the edx system is somewhat bloated, dependent on too much, not too lightweight.

Eax, EBX, ECx, EDX, ESI, EDI, EBP, ESP, etc. are the names of General registers on the CPU in x86 assembly language, and are 32-bit registers. These registers can be viewed as variables in C language. For example:Add eax,-2;// It can be considered that a value such as-2 is added to the variable eax. These 32-bit registers have multiple purposes, but each of them has "expertise" and has its own special features. EaxIt is an accumulator, which is t
