Prerequisite: Your CD can be started directly, recommended to use the CD to start the installation. First, the preparatory work: 1. Note the size of each partition before installation, to facilitate the selection of partitions to check to avoid operation errors, loss of useful data. 2. Ready to create a Linux desktop system co-create 1.0.3 installation CD. Baby-i386-disc.iso The official Free download address is: Ftp://ftp.opendesktop.net/1.0.3/BABY

Co-process, also known as micro-threading, fiber. English name Coroutine.The concept of the co-process was raised early, but it has not been widely used in some languages (such as LUA) in recent years.subroutines, or functions, are hierarchical calls in all languages, such as a call to b,b in the execution of a call to C,c execution complete return, b execution is finished, and finally a executes.So the sub

2018 the beginning of the new year, but the block chain this huge stone has undoubtedly been thrown into the internet, and stirred up layers of ripples, causing the people to pay attention to, everyone stared at the block chain, and swing ripples also fluctuate to major industries and personal interests. The stock prices of listed companies on the block chain soared, and even some changed the company name to "block chain company", in order to raise the stock price, want to take the opportunity b

Multitasking systems generally need to solve a problem: How multiple tasks are scheduled. Preemptive scheduling is a very common task scheduling mechanism. In the single-core mode of process scheduling as an example, a process is running, the other is in the ready queue, until the current running process to abandon the use of the CPU, the system will immediately assign the CPU to the newly arrived process, because the order of execution of the task is not deterministic, it looks like a bunch of

Co-process, also known as micro-threading, fiber. English name Coroutine. One sentence explains what a thread is: The process is a lightweight thread that is user-state .The co-process has its own register context and stack. When the schedule is switched, the register context and stack are saved elsewhere, and the previously saved register context and stack are restored when it is cut back.The greatest adva

The process is actually a thread that can be controlled autonomously by the program.In Python, which is dominated by yield and yield from, it is possible to understand the co-process through the creator consumer exampleUse yield from to transfer data to the generator (co-process)# Traditional producer-the consumer is a thread that writes messages, a thread takes messages, controls the queue through a lock m

1, co-process: A program control mechanism. Asymmetric co-operation: provides two types of control over the transfer program. One is to call the association, and the other is to suspend the current process and return the program control to the caller of the process; symmetric: There is only one operation of the control of the transfer program, and the control right is passed directly to the specified
