[Warning] incompatible implicit declaration of built-in function ‘strcat’

After watching the machine learning course today, I changed to Learn C language for a while. It was also the first time I encountered the strcat function, the string concatenation function. Its general form is strcat (character array 1, character array 2). The function concatenates the strings of two character arrays, attaches string 2 to the end of string 1, and places the result in character array 1. The function call returns a function value — the address of character array 1. Such as:

#include<stdio.h>
int main()
{
	char str1[30] = {"People's Republic of "};
	char str2[] = {"China"};
	printf("%s",strcat(str1,str2));
	
	return 0;
}

Output code error:

In function 'main':
[Warning] incompatible implicit declaration of built-in function 'strcat'

Baidu once reason, little added header file

#include<stdlib.h>

#include<string.h>

After adding, the program output is normal:

Relative path and absolute path${ pageContext.request.contextPath }

Exe
relative path: the path from the current path, if the current path is C:\ Windows
to describe the path, just type
system32\ CMD. Exe
in fact, the strict relative path should be
.\system32\ CMD. Exe
, where. Represents the current path, which can be omitted in channel cases, but not in special cases.
if the current path is c:\program files
to invoke the above command, you need to type
.. \ Windows \system32\cmd.exe
where.. Is the parent directory.
if the current path is c:\program files\common files
then you need to enter
… .\windows\system32\cmd.exe
Hold on, this should make a lot more sense than it does in the program.
The ${pageContext. Request. ContextPath} is equivalent to the & lt; %=request.getContextPath()%> or you could say < %=request.getContextPath()%> EL version of
means to remove the deployment of the application name, or the current project name
such as my project name for SpringMVC in the browser input for http://localhost:8080/SpringMVC/login.jsp
The ${pageContext. Request. ContextPath} or & lt; %=request.getContextPath()%> is to take out/for SpringMVC, and "/" represents the meaning of is http://localhost:8080
so we project should write ${pageContext. Request. ContextPath}/login JSP
Just give me some examples. I'm going to start with the relative path, and in a lot of cases I'm going to get it right.

You see the delete, I also use the relative path, why it won't go wrong for me, because the request path only one layer, there is no placeholder, when converting HiddenHttpMethodFilter delete request will remove a layer, so will not go wrong, the request path into http://localhost:8080/emp/1001

but this edit is not so optimistic.

There is a placeholder in the path, so the conversion will not be complete.

This is the kind of farce that occurs when multiple layers of requests have no path for a Handler to process in the first place.
So use relative paths as often as possible.

HBase checkandput() method

The common method for adding (modifying) data in a table in Hbase is void put(put put), which returns no value
But if you put the same data, you get an error, which is not very friendly
So, there’s also the checkAndPut() method

   * Atomically checks if a row/family/qualifier value matches the expected
   * value. If it does, it adds the put.  If the passed value is null, the check
   * is for the lack of column (ie: non-existance)


boolean checkAndPut(byte[] row, byte[] family, byte[] qualifier,
    byte[] value, Put put) throws IOException

If the data (Row, family, Qualifier, value) is present, then put will not be performed and false will be returned; otherwise, true will be performed
Therefore, this method is safer than the put() method.

Windows 10 startup item repair an operating system wasn’t found

Recently, in the dual systems deepin15(Ubuntu is also applicable) and Windows10, a series of problems encountered when uninstalling Deepin are recorded as follows: after installing Deepin system in
Windows, the general boot will change into Deepin boot, which will cause the boot item to disappear, and the system will not automatically restore win boot, resulting in the failure to enter the system normally. Before deleting deepin’s partition, I could use Deepin’s official unload instruction to instruct me to use. However, it was invalid, so I had to delete the partition by myself, and then started it with the U disk for repair.
(1-2 steps) needs to be made on another working computer

    download old peach or U boot or Chinese cabbage. And install. Insert the USB flash drive and make it with one click. When finished, unplug the usb flash drive. Insert the usb flash drive into the computer that cannot be started normally, press F12 to select the entry of the usb flash drive (the name is usually the manufacturer of your usb flash drive). Select windows8 to boot your new computer. Wait for normal entry. Open DiskGenius, change the disk to the one that was in good condition before (normally, starting from the USB drive will change the initial disk character), and use the boot repair software to fix it automatically. Exit reboot.

If the Win system can be started normally after 6 is completed, the latter can be ignored. Otherwise, if an operating system wasn’t found appears, press CTRL+ALT+DEL to restart something. Reboot or repeat above 3-5 (not 6). And follow the steps below to continue

    after entering the PE system, click the Windows logo in the lower left corner and find Dism++ in the folder. Open, the top bar to find the system where the partition, and click, find tools repair boot. Reboot, and that’s it.

Get the Yahoo data in Python

18:42:54, June 11, 2018

Reading count: 71

I learned machine learning in Python. I found a practical tutorial online. I needed to get stock data from Yahoo. The problems and solutions are given below.
Programming environment: Linux Ubuntu16, python3.6, anaconda 1.6.14, conda 4.5.4, pandas 0.23
= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =
Problem 1: An environment interpretation error occurred while downloading Pandas _datareader
Because the Yahoo data needs to be retrieved through the Pandas _datareader module, you need to download and install the package
Environment parse error occurs with Conda Install Pandas _datareader (conda installation is used because anaconda is used to build the Python compile and edit environment) :

python@ubuntu:~$ conda install pandas_datareader
Solving environment: failed

PackagesNotFoundError: The following packages are not available from current channels:

  - pandas_datareader

Current channels:

  - https://repo.anaconda.com/pkgs/main/linux-64
  - https://repo.anaconda.com/pkgs/main/noarch
  - https://repo.anaconda.com/pkgs/free/linux-64
  - https://repo.anaconda.com/pkgs/free/noarch
  - https://repo.anaconda.com/pkgs/r/linux-64
  - https://repo.anaconda.com/pkgs/r/noarch
  - https://repo.anaconda.com/pkgs/pro/linux-64
  - https://repo.anaconda.com/pkgs/pro/noarch

To search for alternate channels that may provide the conda package you're
looking for, navigate to

    https://anaconda.org

and use the search bar at the top of the page.

Solution 1: Then change to PIP Install safari _datareader to install successfully!
Solution two: Later, I found that when I was using Conda to install the module, there were jupyter Notebook still running, so I tried to close it and then used Conda install Rebuild _datareader to find it could be successfully installed.
 
Question 2: ImportError: Cannot import name ‘is_list_like’ when using import pandas_datareader as PDR
I found many methods on the Internet, including the case column on StackFlow, but I still couldn’t find one suitable for me.
Solution one: Then give up searching for a solution online and start groping instead. Because the error message is that the module named ‘is_list_like’ cannot be imported, the code to find the error is in the first line from pandas.core.common.data import is_list_like in the fred.py module. Because the common folder and the modules under that folder cannot be found in the environment, the path to import is_list_like is wrong.
Then, Baidu search: panda IS_list_like finds the official API document of Pandas, and click Source to enter the source code module. It turns out that IS_list_like exists as a method of in the following path

Finally, I get rid of the Fred. Py the first line of the import path into: from pandas. Core. Dtype. Inference import is_list_like, import pandas_datareader modules again success!
 
Question 3: run the following code, appear ImmediateDeprecationError, namely the Yahoo! Finance no longer exists because in 2017 Yahoo! It was bought by Verizon

Yahoo Daily has been immediately deprecated due to large breaks in the API without the  
introduction of a stable replacement

The code is as follows:

     

    import pandas as pd

     

    import datetime

     

    import pandas_datareader.data as web

     

    start = datetime.datetime(
    2010,1,1)

     

    end = datetime.datetime(
    2017,1,1)

     

    df = web.get_data_yahoo(
    ‘SPY’,’yahoo’,start, end)

Baidu has found one solution in the CSDN blog: install Fix_yahoo_finance (PIP Install) and then run the following code before retrieving the data.

     

    import fix_yahoo_finance as fy

     

    fy.pdr_override()

On NPM audit fix

Background:
The following reminder appears when NPM Install is executed

added 253 packages from 162 contributors and audited 1117 packages in 42.157s
found 5 vulnerabilities (1 low, 4 high)
  run `npm audit fix` to fix them, or `npm audit` for details html

According to the command prompted by the console, type ‘NPM Audit Fix’ and the console prompts:

1 package update for 5 vulns involved breaking changes
  (use `npm audit fix --force` to install breaking changes; or do it by hand)

After typing: ‘NPM Audit Fix — Force’, the console prompts:

added 199 packages from 111 contributors, removed 64 packages and updated 23 packages in 42.194sfixed 5 of 5 vulnerabilities in 1117 scanned packages
  1 package update for 5 vulns involved breaking changes
  (installed due to `--force` option)

Re-enter ‘NPM Audit’ :

                      === npm audit security report ===

found 0 vulnerabilities
 in 4598 scanned packages

At last everything was all right.
Out of curiosity, I read the introduction of NPM Audit Fix on the official website of NPM.
NPM audit: [email protected]& amp; NPm@6, which allows developers to analyze complex code and identify specific vulnerabilities and defects.
NPM Audit Fix: [email protected] detects vulnerabilities in project dependencies and automatically installs those that need to be updated without having to track and fix them themselves.
In the meantime, the website also provides some other commands, which are summarized as follows:
1. Run audit Fix, but only update PKglock, not Node_modules:

$ npm audit fix --package-lock-only

2. Update only the packages installed in Dependencies, and skip the packages in devDependencies:

$ npm audit fix --only=prod

3. Run the command to get the contents of the audit Fix to be updated and output the installation information in JSON format, but the update is not actually installed:

$ npm audit fix --dry-run --json

4. Get the detailed test report in JSON format

$ npm audit --json

Resolve the problem of “event ID 4107” or “event ID 11” errors recorded in the application logs of windows and windows server

Problem description
An error similar to the following was logged in the application log on a machine running Windows 7 or Windows Server 2008 R2:
Log name: application
source: microcosm-windows-capi2
date: date and time
event ID: 4107
task category: no

Or, an application log on a machine running Windows Vista or Windows Server 2008 records an error similar to the following:
Log name: application
source: microcosm-windows-capi2
date: date and time
event ID: 11
task category: no
level: error

why
The above error occurred because the Microsoft Certificate Trust List publisher certificate has expired. A copy of the CTL whose signature certificate has expired exists in the CryptnetUrlCache folder.
In addition, the event ID 4107 May be logged as a “data invalid” error rather than a “Certificate that is not valid when verified against the current system clock or timestamp in the signature file” error.
