List of lecture lecturers
1. Modify HTML file
Copy the contents of the org-list.html page to teacher-list.html to replace crumbs and conteng content.
2. Writing URL and VIEW
Because Teacher’s model is in the defined organization / models. py, you can define the instructor’s URL in organization / urls. PY

Here are the questions.
Considering the first and second numbers x, y, we can find that S is determined only on the highest bit of (x XOR y) (if x = = y is not restricted), and we can deduce what is 1/0.
So let’s simulate this operation and decide if there’s any contradiction in the restriction. If there’s no contradiction, the answer is 2 ^ free bit.
#include<bits/stdc++.h>
#define ll long long
using namespace std;
int n,ban[67];
ll now,pre,Xor,c[67],ans=1;
int main(){
scanf("%d",&n),fill(ban,ban+60,-1);
c[0]=1; for(int i=1;i<=60;i++) c[i...
Difference:
TOSAnd DSCP are the fields in the three tier protocol (IP layer).
COSIt is the field in the two tier protocol.
Detailed:
TOSDefined in different protocols, RFC 791, RFC 122, RFC 1349; RFC 1349 abolished the previous two RFC definitions, and now most devices use RFC 1349.
DSCPDefined by RFC2474, the 1 byte of the TOS and Traffic Class in the IPv4 header is renamed. The new name is the DS field, which is still used by QoS tools to annotate data.

Research on cloud storage security in the environment of Internet of things
The Internet of Things (IOT) is a kind of network which uses computer technology, Internet technology, communication technology, sensor technology and other technologies to connect goods with the Internet in order to realize the functions of information transmission, intelligent identification, goods management and so on.
With the extensive attention of cloud computing technology, cloud storage technology has also received extensive attention. Cloud storage can integrate a variety of storage devices ...
1. >base.ldifFiles, DC and configuration files in the same consistency.
dn: dc=dc,dc=com
o: ldap
objectclass: dcObject
objectclass: organization
2）Then execute the command to import the database.
ldapadd -f base.ldif -x -D cn=root,dc=dc,dc=com -W
It will prompt you to enter the password. If you add it, you will be prompted to add a new node.
Enter LDAP Password:
adding new entry “dc=dc,dc=com”
3）
According to the tutorial, it was wrong to add and save quest.
1.models.pyThere is no mistake in naming it.
2.Check INSTALLED_APPS under mysite-> settiongs settings are correct.
3.Using Python manage.py makemigrations polls has no modified content.
4.Check 0001_***.py normal
Resolvent:
1.Delete all files except __init__.py under migrations.
2.python manage.py makemigrations polls
3.python manage.py migration
4.View database has generated corresponding table
Cross-compiler tool chain is a comprehensive development environment composed of compiler, connector and interpreter. Cross-compiler tool chain is mainly composed of binutils, GCC and glibc.
The free version is currently available from three mainstream vendors: GNU, Codesourcery and Linora.
1、aarch64-linux-gnu-gcc：It is a ARM cross compilation tool launched by Linaro company based on GCC. It can be used to cross-compile bare computer programs, u-boot, Linux kernel, filesystem, and App applications in ARM V8 64-bit targets.
2、arm-none-linux-gnueabi-gcc：Codesourcery (now acquired b...
