Premise:1. Install Ubuntu2. use vagrant+virtualbox to build the EdX Developer Stackon ubuntn and to successfully access3. 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. A few days ago a friend of Peking University in the insta

After practicing for several days edx Devstack, found himself e is still so poor, if and I like, continue to look down, otherwise you can gently drift over ~1.

Note: During addition calculation, it is actually performed on a 32-bit accumulators, and pay attention to the conversion between types. Data truncation problems generally include ax, BX, CX, Dx. Ax: cumulative latches, Bx: Base latches, CX: Count latches, DX: Data latches Index latches: Si and Di Si: source index storage, DI: Destination index Storage Stack and base latches: SP and BP SP: stacked indicator latches, BP: Base Indicator latches Eax, ECx,

When programming to Arduino, because there is no debugging tools, often through the use of serial communication to call Serial.print and SERIAL.PRINTLN output Arduino running the relevant information, and then on the computer with the Arduino The IDE's serial monitor to see the print out information. Serial Monitor not only accepts data that

Recently, due to work, an open EdX instance was installed in Ubuntu virtual machine on Azure, and the installation process encountered a lot of problems, and learned different knowledge in the process of finding the answer from the Internet.Create an authentication certificate file for SSHWhen connecting to an Ubuntu virtual machine using the Putty (http://www.putty.org/) tool, two options are available for authentication: username + password; Another

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
