Wget

Wget is a free and very powerful file downloader that comes with a lot of useful features including resume support, recursive download, FTP/HTTPS support, and etc. In “The Social Network” movie, Mark Zuckerberg is seen using the Wget tool to download all the student photos from his university to create Facemash. Wget is a command line tool which can be a bit difficult to use for some basic users.

Thankfully there are free front-end GUI’s for Wget such as VisualWget that makes it so much easier to use Wget by simply clicking on the check boxes rather than manually typing the command line arguments. Download VisualWget, extract and run VisualWget.exe. Click on the New icon to open a New Download window. Enter the URL that you want to download and select the location that you want to save the files to.

If you need to download multiple folders including subfolders, go to Advanced, click on Recursive Retrieval and tick on the first checkbox “–recursive“. Finally click OK to start downloading.

Although there are a few GUIs for Wget, we recommend VisualWget because it is free, portable, comes together with Wget and there is no need to download separately and manually unpacking it to the program’s folder or even configuring the path.

Change firmware type for VMware Workstation 15.1 player.

Solved by adding 1 line of config into vmx file in your target VM.

Reference URL: https://www.serverwatch.com/server-tutorials/enabling-uefi-on-virtual-machines.html

UEFI support must be enabled by manually editing the .VMX file or by using a third-party tool like VM Tweaker.
To manually edit the .VMX file, simply open with a text editor and add the following line and then save:
firmware = "efi"That's it — now that particular VM should run with UEFI.

All guides from google are for VMware Workstation 15.1 Pro.

For JUnit test with spring, either you load context configuration:

1. manual parse xml [ApplicationContext _ctx = ClassPathXmlApplicationContext( "abc/xyz/spring-context-all.xml" ) ], access beans via _ctx.getBean()
2. or annotation to let spring auto wired all your attributes of test cases.

And using annotation of @ContextConfiguration, I've preference to use classpath for reasons below:

1. Spring JUnit test cases able to share xml info.
2. multi developer environment competible.

taking this advice:

Eclipse Code Recommenders Mylyn Integration makes Mylyn’s task‐focused Java proposals available in Code Recommenders’ intelligent code completion. Install this feature if you want to use the Mylyn Task‐Focused Interface in conjunction with Eclipse Code Recommenders.

Uninstall Code Recommenders Mylyn Integration

But still having the exception message.

1、点击报错的那个连接`（Window -&gt; preferences -> java -> Editor -> Content Assist -> Advanced）`。
2、再打开的配置了面将`Default Proposal Kinds`栏中`Java Proposals (Code Recommenders)`前面的对勾去掉就可以了。
3、生效后，我的就没有提示，然后又将剩余的两个`Java Proposals`、`Java Proposals（Task-Focused）`打上对勾才正常。

Resolved: The import org.hibernate.annotations.CreationTimestamp cannot be resolved

By refering to: https://stackoverflow.com/questions/32090921/deploying-maven-project-throws-java-util-zip-zipexception-invalid-loc-header-b

Solve by delete the .m2\repository\org\hibernate\hibernate-core\5.3.3.Final
And did a Maven Update.


Awaiting to verify: might triggered by migrated from Oracle JDK to AdoptOpenJDK





Initially thought was causing by Builders of Spring(Spring Project Builder& Spring Boot Validations Builder) was not there.

Project Natures also missing Spring relevant component.

Then the import org.hibernate.annotations.CreationTimestamp cannot be resolved

Found exists in Maven Dependency.

But when double click the CreationTimestamp.class, it shows invalid LOC header (bad signature).

Use a separated list of of processes:

#!/bin/bash
PROC="nginx mysql ..."
for p in $PROC
do
  ps cax | grep $p > /dev/null

  if [ $? -eq 0 ]; then
    echo "Process $p is running."
  else
    echo "Process $p is not running."
  fi

done

If you simply want to see if either one of them is running, then you don't need loo. Just give the list to grep:

ps cax | grep -E "Nginx|mysql|etc" > /dev/null

To exclude by using:


ps -ef | grep -vE "grep|vim |tail " | grep tomcat
