If there’s a problem in your .bashrc or .tmux.conf files, Cloud Shell immediately close after connection. To resolve this, open Cloud Shell in safe mode by appending cloudshellsafemode=true to the URL. This restarts your Cloud Shell instance and logs you in as root, allowing you to fix any issues in the files.
To permanently delete all files in your home directory and restore your Cloud Shell home directory to a clean state, you can reset your Cloud Shell VM.
I knew there was JSFiddle for live playing around with JavaScript and more in your browser, so I wondered if there was a similar site for databases and SQL queries.
There are, so here are a few database fiddle sites: SQL playgrounds where you can live play with SQL queries (sometimes even without an underlying example database).
Python:
>>> print(1+2+" = "+2+1)
Traceback (most recent call last):
File "", line 1, in
TypeError: unsupported operand type(s) for +: 'int' and 'str'
Java:
System.out.println(1+2+" = "+1+2);
3=12
php8.1 -r 'print 1+2+" = "+2+1;'
PHP Fatal error: Uncaught TypeError: Unsupported operand types: int + string in Command line code:1
Stack trace:

thrown in Command line code on line 1
php7.3 -r 'print 1+2+" = "+2+1;'
PHP Warning: A non-numeric value encountered in Command line code on line 1
Node?
Chrome & FF dev console:
window.alert(1+2+" = "+1+2)
3 = 12
Sind ja immerhin verschiedene Sprachen.
SELECT Wert1
FROM table1
WHERE Wert1 < AVG(Wert1);
DB2 vs. Oracle vs. MSSQL vs. ....
The joke is that Python actually does better than Java.
A while ago, I wanted to convert the dl delimited list htmlelement on a web page into a regular table so I could more easily reorder the data into cells.
So I ran the below bit of code in the Chrome Console after first putting the mentioned table with id here_table in the place where I wanted the table to be included:

On iOS, the Safari is the only system browser engine whereas on Android you can have other engines too, so less Android applications have in-app browsers.
Most of those in-app browsers are in social media applications that go to great length to keep their users inside a walled garden.
The site [Wayback/Archive] inAppBrowser.com helps checking how severely information is leaked through the in-app browser as those potentially have a lot of control. TikTok is worst capturing all input including credentials like user names and passwords.
WebGoat is a deliberately insecure web application maintained by OWASP designed to teach web application security lessons.
This program is a demonstration of common server-side application flaws. The exercises are intended to be used by people to learn about application security and penetration testing techniques.
WARNING 1:While running this program your machine will be extremely vulnerable to attack. You should disconnect from the Internet while using this program. WebGoat’s default configuration binds to localhost to minimize the exposure.
WARNING 2:This program is for educational purposes only. If you attempt these techniques without authorization, you are very likely to get caught. If you are caught engaging in unauthorized hacking, most companies will fire you. Claiming that you were doing security research will not work as that is the first thing that all hackers claim.
This repository contains all the lessons for the WebGoat container. Every lesson is packaged as a separate jar file which can be placed into a running WebGoat server.
This is the WebGoat Legacy version which is essentially the WebGoat 5 with a new UI.
This program is a demonstration of common server-side application flaws. The exercises are intended to be used by people to learn about application penetration testing techniques.
The Open Web Application Security Project (OWASP) is an online community that produces freely-available articles, methodologies, documentation, tools, and technologies in the field of web application security.[4][5]The Open Web Application Security Project (OWASP) provides free and open resources. It is led by a non-profit called The OWASP Foundation. The OWASP Top 10 – 2021 is the published result of recent research based on comprehensive data compiled from over 40 partner organizations.
The OWASP Top 10 is a standard awareness document for developers and web application security. It represents a broad consensus about the most critical security risks to web applications.
Globally recognized by developers as the first step towards more secure coding.
Companies should adopt this document and start the process of ensuring that their web applications minimize these risks. Using the OWASP Top 10 is perhaps the most effective first step towards changing the software development culture within your organization into one that produces more secure code.
Changes in the OWASP Top 10 between 2017 and 2021:
