[HDGEM] Google sitemap limitation

All sitemap formats limit a single sitemap to 10MB (uncompressed) and 50,000 URLs. 
If you have a larger file or more URLs, you will have to break your list into multiple sitemaps. You can optionally create a sitemap index file (a file that points to a list of sitemaps) and submit that single index file to Google. You can submit multiple sitemaps and/or sitemap index files to Google.

[HDGEM] Your site will benefit from having a sitemap

Using a sitemap doesn't guarantee that all the items in your sitemap will be crawled and indexed, as Google processes rely on complex algorithms to schedule crawling. However, in most cases, your site will benefit from having a sitemap, and you'll never be penalized for having one.

[HDGEM] How to fix - javax.ejb.AccessLocalException: Client not authorized for this invocation

One possible fix is that cache of application server because you make some modification in the existing EJB class.

To solve this problem you just need to clear the cache and restart the app server.

For example, for Glassfish/Paraya Java EE application server, go to folder/directory "generated" in domain folder, and restart your server to refresh.

[HDGEM] JAX-RS 2.0 includes a brand new API for asynchronous processing

It includes server as well as client side counterparts.

Being asynchronous inherently implies request processing on a different thread than that of the thread which initiated the request.

• From a client perspective, it prevents blocking the request thread since no time is spent waiting
for a response from the server.
• Similarly, asynchronous processing on the server side involves suspension of the original
request thread and initiation of request processing on a different thread, thereby freeing up
the original server side thread to accept other incoming requests.

[HDGEM] Caching in JAX-RS

• From a JAX-RS perspective, caching does not imply a server side cache
• It just provides hints to the client in terms of the durability/validity of the resource data
• It does not define how the client will use this hint. It ensures that it sticks to the HTTP
semantics and assumes that the client (e.g. a browser, programmatic API based client etc.)
understands the HTTP protocol

[HDGEM] JAX-RS Interceptors vs filters

Interceptors are similar to filters in the sense that they are also used to mutate HTTP requests and
responses, but the major difference lies in the fact that Interceptors are primarily used to manipulate
HTTP message payloads.

They are divided into two categories - javax.ws.rs.ext.ReaderInterceptor
and javax.ws.rs.ext.WriterInterceptor for HTTP requests and responses respectively.

[HDGEM] Server side Response filter

A server side Response filter is invoked by the runtime after a response (or an exception) is generated by the JAX-RS resource method (before dispatching the same to the caller/client).  Response filters are similar to their counterparts (Request filters) in terms of their utility (read/mutate aspects of the response e.g. HTTP headers) and programming model (executed as a chain in a user
defined or default order)

Setting up a server side response filter is as simple as providing an implementation for the javax.ws.rs.container.ContainerResponseFilter interface. The injection of
ContainerResponseContext into the filter method of the ContainerResponseFilter interface is taken
care of by the JAX-RS runtime.

Response filters also need to be annotated with the javax.ws.rs.ext.Provider annotation in order for the JAX-RS runtime to recognize it automatically.

[HDGEM] Server side Request filter

Server side request filters act on incoming HTTP requests from the clients and provide an opportunity to act on/make decisions based on certain characteristics of the HTTP request.

In order to implement a server side request filter, one needs to implement the javax.ws.rs.container.ContainerRequestFilter interface (which is an extension provided by JAX-RS).

An instance of the javax.rs.ws.ContainerRequestContext interface is seamlessly injected by the container into the filter method of ContainerRequestFilter. It is a mutable object (on purpose) and exposes methods to access and modify HTTP request components.

A JAX-RS request processing pipeline involves dispatching a HTTP request to the appropriate Java
method in the resource classes based on matching algorithm implemented by the JAX-RS provider.
Filters take this into account and are divided into pre and post matching filters.

[HDGEM] JAX-RS Provider Filters

Filters provide AOP (Aspect Oriented Programming) like capabilities within JAX-RS applications Filters allow developers to implement cross cutting application specific concerns which ideally should not be sprinkled all over the business logic e.g. authentication, authorization, request/response
validation etc.

The AOP-based programming model involves interposing on methods of JAX-RS resource classes and dealing with (or mutating) components of HTTP request/response - headers, request URIs, the invoked HTTP method (GET, POST etc)

[HDGEM] JAX-RS specification does not define dedicated security related features

Except for a few API constructs (which act as high level abstractions).

For server side JAX-RS users (Java EE) it's critical to understand that the JAX-RS framework leverages the security capabilities of the container itself.

To be specific, since JAX-RS is built on top the Servlet API, it has access to all the security features
defined by the specification.

[HDGEM] Spring Cloud provides tools for developers to quickly build some of the common patterns in distributed systems

Spring Cloud provides tools for developers to quickly build some of the common patterns in distributed systems (e.g. configuration management, service discovery, circuit breakers, intelligent routing, micro-proxy, control bus, one-time tokens, global locks, leadership election, distributed sessions, cluster state). Coordination of distributed systems leads to boiler plate patterns, and using Spring Cloud developers can quickly stand up services and applications that implement those patterns. They will work well in any distributed environment, including the developer's own laptop, bare metal data centres, and managed platforms such as Cloud Foundry.

[HDGEM] Python is an extremely elegant and simple language with one of the core design’s tenets being readability.

Python can be written in an object-oriented, procedural, or even functional way, and it is an interpreted language, meaning that it is not compiled.
In comparison to C++, Java, and C#, Python code is often much more terse since more can be expressed in fewer lines of code.

Python is extremely popular today and is growing in popularity

[HDGEM] Mail-in-a-Box is an open source software bundle that makes it easy to turn your Ubuntu server into a full-stack email solution for multiple domains.

Mail-in-a-Box is designed to handle SMTP, IMAP/POP, spam filtering, webmail, and even DNS as part of its all-in-one solution. 
Since the server itself is handling your DNS, you'll get an off-the-shelf DNS solution optimized for mail. Basically, this means you'll get sophisticated DNS records for your email (including SPF and DKIM records) without having to research and set them up manually. You can tweak your DNS settings afterwards as needed, but the defaults should work very well for most users hosting their own mail.

For securing the server, Mail-in-a-Box makes use of Fail2ban and an SSL certificate (self-signed by default). It auto-configures a UFW firewall with all the required ports open. Its anti-spam and other security features include graylisting, SPF, DKIM, DMARC, opportunistic TLS, strong ciphers, HSTS, and DNSSEC (with DANE TLSA).
