developed the standard IEEE Std 1149.1 for standard test port and boundary scan, which is the JTAG interface protocol. The JTAG interface uses four signal lines: TCK, TDI, TDO, and TMS to provide connectivity tests for various pins of the complex chip in serial mode, the progress also enables the configuration of the programmable chip and debugging of the processor chip. Download cable is a cheap tool that uses the parallel port of a computer to impl
The Linux time function is in the time.h header file.1. header fileThe time-related header files are as follows:Time.hSys/time.hSys/times.hSys/timeb.hSys/timex.hTime.h is the header file for the C standard library, and the rest of Sys starts with the Linux system's own header files./usr/include/time.h defines the commonly used time functions.To view these files in the/usr/include/sys directory:Sys/time.h defines the time functions of the TIMEZONE structure and the Linux system.SYS/TIMES.H define
For several days did not write a blog, recently to test, have C language. Originally prepared to deal with the exam, casually learn, and then prepare for the next semester with C to learn the data structure and algorithm, but, watched some video, ready to enter the pit C/s .... I learned nearly a semester of C #, so give up feeling or some small reluctant to ... But technology is common, and it's not a waste of time.Then post the code:1 intnum[Ten];2 time_t

Basic Principles of JTAG
JTAG (joint test action group) is an international standard test protocol (IEEE 1149.1 compatible ). The standard JTAG interfaces are 4-wire-TMS, tck, TDI, and TDO, which are the mode selection, clock, data input, and data output lines

You can see the dashboard at a glance in the car cockpit, using the dashboard made by using Echarts can easily display the user's data, clearly see the scope of a certain indicator value, the dashboard form of the report used in a variety of statistical systems, this article combined with examples to explain the instrument panel in the sales task completion rate
Once upon a while, the user story was written into the classic sentence of user stories + acceptance conditions.A sample of the following story is provided on the https://blog.versionone.com/agile-acceptance-criteria/.
As an executive, I want to is able to filter the dashboard by department so this I can isolate data by a specific departme Nt.
Acceptance Criteria:
Given the Executive Dashboard default view,
describe what I expect to observe on page loading. TDD allows me to focus on one problem at a time, write only enough code to pass the test, and then proceed. In this test, I will use a simulated object framework named NMock2 to build an interface simulation implementation.
Figure 3 MVP charts
In my MVP implementation, I decided to attach the dashboard to the view that will work with it. It is always good to create an object when the object can work
Elasticsearch Kibana Installation notes
Kibana is a dashboard used for ElasticSearch analysis and query. It is worth noting that Kibana puts the analysis before the query, which is probably distinguished by other clients.
For more information about Kibana, see here.

In addition, I still use head and bigdesk. Of course, their positioning is almost different. Head is easy to use for data browsing and query. bigdesk is used for ElasticSear
