Add these properties to an image:

img {
max-width: 100%;
height: auto;

The max-width of 100% will make sure the image is never wider than the container it is in, and the height of auto will make the image keep its original aspect ratio.

Markdown Editors can speed up the formatting process

Markdown is much easier to compose than HTML. You can export in multiple formats The best Markdown editor will make it easy to write your content and quickly export it to PDF, web pages, or Rich Text Format.
You can work on cross-platform Since there are dozens of really good Markdown editors for all platforms (Linux, Mac, Windows, web, etc.), you can pretty much write and edit text from any device and location.
This can bring a massive difference in your productivity.

VS Code supports Markdown files out of the box.

You just start writing Markdown text, save the file with the .md extension and then you can toggle the visualization of the editor between the code and the preview of the Markdown file; obviously, you can also open an existing Markdown file and start working with it.

The AWS SAM CLI comes with abstractions for a number of Lambda runtimes to build your dependencies

The AWS SAM CLI comes with abstractions for a number of Lambda runtimes to build your dependencies, and copies the source code into staging folders so that everything is ready to be packaged and deployed. The sam build command builds any dependencies that your application has, and copies your application source code to folders under .aws-sam/build to be zipped and uploaded to Lambda.

Retrieves your account's AWS CloudFormation limits.

Such as the maximum number of stacks that you can create in your account:
$ aws cloudformation describe-account-limits { "AccountLimits": [ { "Name": "StackLimit", "Value": 200 }, { "Name": "StackOutputsLimit", "Value": 60 }, { "Name": "ConcurrentResourcesLimit", "Value": 2500 } ] }

AWS CloudFormation enables you to create and provision AWS infrastructure deployments predictably and repeatedly.

It helps you leverage AWS products such as Amazon EC2, Amazon Elastic Block Store, Amazon SNS, Elastic Load Balancing, and Auto Scaling to build highly reliable, highly scalable, cost-effective applications in the cloud without worrying about creating and configuring the underlying AWS infrastructure. AWS CloudFormation enables you to use a template file to create and delete a collection of resources together as a single unit (a stack).

Let’s Encrypt is one of the trusted certificate authorities that provides domain validated certificates

Let's Encrypt's domain validated certificates are trusted by most browsers. It uses the Automatic Certificate Management Environment (ACME) protocol for validation, which sends a challenge to verify that you actually control your domain name. This service is widely used because it's easy and free to get a certificate.

HTML5 web worker specification provides a standard API for spawning new background threads and enables concurrency in web apps.

Web workers execute scripts in isolated threads and do not share resources with the main UI thread. The script executed by the workers has to be in a separate file. This allows web workers to perform their tasks without interfering with a main thread and without interrupting the user interface.

Java new line "%n" vs "\n" in printf

There is also one specifier that doesn't correspond to an argument. It is "%n" which outputs a line break. A "\n" can also be used in some cases, but since "%n" always outputs the correct platform-specific line separator, it is portable across platforms whereas"\n" is not.

Limits on Table Column Count and Row Size - MySQL

The internal representation of a MySQL table has a maximum row size limit of 65,535 bytes, even if the storage engine is capable of supporting larger rows. BLOB and TEXT columns only contribute 9 to 12 bytes toward the row size limit because their contents are stored separately from the rest of the row.

Pivot enables developers to build solutions using the tools they already know, decreasing delivery time and reducing technology sprawl.

Pivot allows developers to easily construct visually-engaging, cross-platform, connected applications in Java or any other JVM language, such as JavaScript, Groovy, or Scala. Pivot is also the only truly open IIA framework: it is completely open source, and is driven entirely by the software development community.

Pivot classes are grouped into the following primary categories

Core - A set of common, non-UI classes.WTK - Classes for user interface development, including windows, dialogs, buttons, lists, text input, layout, drag and drop, etc.Web - Classes to facilitate implementation of and communication with remote data services.Charts - Classes for adding interactive charting capabilities to Pivot applications.The classes in each category are packaged and distributed in a corresponding library or set of libraries

Scripting for the Java Platform is a framework for embedding scripts into Java source code.

BXML is an XML-based markup language for simplifying the construction of Java object hierarchies.

While BXML is most often used to define the user interface of an Apache Pivot application, it is not limited to user interface construction, and can actually be used to create hierarchies of any object type. In the case of Apache Pivot the designer can place the WTK-components and set their properties without writing a single line of Java code. In more complex projects there usually is one class file for each BXML file to hold the logic, though there are other possibilities.

Apache Pivot is an open-source platform for building rich web applications in Java or any JVM-compatible language.

AWS CloudFormation Template is a declaration of the AWS resources that make up a stack.

The template is stored as a text file whose format complies with the JavaScript Object Notation (JSON) or YAML standard. Because they are just text files, you can create and edit them in any text editor and manage them in your source control system with the rest of your source code.

You can define AWS Cloudformation templates as YAML, but they will ultimately be processed into JSON.

AWS CloudFormation Macros transform statements in your template.

AWS CloudFormation custom resources manage the lifecycle of resources outside of what is defined in the AWS CloudFormation template.

The reason one can use recursion to solve a problem is that one big problem can be divided into multiple subproblems and each subproblem follow the same logic and structure.

All coding problems that can be formatted into tree structures are mostly can be solved by either breadth first search or depth first search.

Different from breadth first search is implemented using stackDepth first search takes a divide and conquer approach which is implemented using recursion.

Disadvantages of Greedy Algorithms: The local optimal solution may not always be global optimal.

Greedy Algorithms works step-by-step, and always chooses the steps which provide immediate profit/benefit.

Greedy algorithms may not always lead to the optimal global solution, because it does not consider the entire data. The choice made by the greedy approach does not consider the future data and choices.
