Today Hyperledger Fabric released the 1.0 beta version of the image, according to the name, this should be a basic available version, so I hastened to download the first time, playing with the play. Here are the steps to install and test Fabric 1.0 Beta in Ubuntu:First, Environment preparation 1.1 install VirtualBox and install Ubuntu in it.This step is actually nothing to say, download the latest version of VirtualBox, download Ubuntu Server, I use 1

Hyperledger Fabric is a modular blockchain architecture that is a unique implementation of distributed bookkeeping technology (DLT), which provides a network that can be used by enterprises with security, scalability, encryption, and executable features. Hyperledger Fabric provides the following blockchain networking capabilities: Identity Management To support a licensed network,

method does not require any additional operations. Now in order to improve the drive performance of stepper motors, we hope that the polarity reversal point behind the output of a few microseconds, to do this hardware method changes is certainly difficult, and the software method only need to increase the timing lag output on the line. In order to reduce the computational overhead, we can use the table-checking method to store the computed SPWM data in ROM and output the values in the table se

There are always bugs in the program development process, so the location and analysis of Bugs is critical.Golang defines a lot of error, but sometimes it is difficult to locate the problem with error, so we still need the stack information.We typically define a function that prints incorrectly, so that errors can be processed and analyzed in a uniform way: func ErrorPbResponse(errCode string, errMsg string) pb.Response { LogMessage("errcode[" + errCode + "] Errmsg:" + errMsg) if errCo

We use the elliptical marquee tool to turn off and turn on anti-aliasing (also known as anti-aliasing), create two roughly large, rounded selections, and then fill the black look. How to quickly fill black do you remember? First 〖x〗 and then 〖alt Delete〗. After the fill deselect 〖ctrl D〗, the effect is shown below. Careful observation of the edges of the two circles, you will see the first round of the edge is more blunt, there are obvious ladder-like, also called
