Procedural macros are a way for you to extend the Rust compiler and provide plugins
that you can use to extend the language. They allow to create your own DSL (domain
specific language). This article goes into the details of creating a simple DSL to
mimic CSS syntax but in Rust, for a TUI app framework.

This article illustrates how we can build a CLI app in Rust that is a very basic implementation of
grep. This app will have 2 modes of operation: piping lines in from `stdin` and searching them, and
reading a file and searching thru it. The output of the program will be lines that match the search
term w/ the term being highlighted. Topics like `stdin` manipulation in a terminal, detecting when
the terminal is in `tty` mode vs `piped` mode, doing simple file I/O, creating non consuming
builders, and managing `Result`s, along w/ building a simple CLI interface are covered in this
article.

Overall, the API is pretty straightforward to use, assuming that you are
familiar with asynchronous processing in the first place. However, if you are not
familiar with asynchronous processing, then this business of callbacks can be quite
confusing and daunting. Additionally Tomcat 7 and Servlet API 3.0 make it easier
to configure servlets using annotations. There are other cool features in 3.0 that
I haven’t covered in this tutorial, like loading servlets programmatically.

The best way to handle GPS is to use the “network” or “passive” provider
first, and then fallback on “gps”, and depending on the task, switch between providers.
This covers all cases, and provides a lowest common denominator service (in the
worst case) and great service (in the best case).

Android applications run in a native Linux process, in the underlying Linux
OS. This process houses activities (screens), widgets, and services (non visual
long running application parts). When working with Android apps, it is important
to remember to keep long running code running in threads that are not tied to the
main thread or event dispatch thread, in order to get an “application not responding”
error. A common mistake that is made is long running tasks are performed in this
EDT/main thread, and this leads to lots of application failures.

This tutorial is an introduction to the built in animation frameworks that

you can do 2 types of animations - layout transitions that affect ViewGroups, and
sequences inside a View. You can also do frame by frame animation, but this tutorial
will not cover that. The basics covered here affect layout transitions, and animation
of a View itself, using tweening animation, which includes each of the following
effects (or any combination) - Alpha, Rotate, Scale, and Translate.

I needed to perform animations in the app that I'm building for ScreamingToaster
desktop app framework using Java and Swing. I needed to build animations that show
a transition from one screen to another.
This is slightly different than creating custom, or modified components which perform
a function and have a set of graphical effects. I needed animations that would transition
my user interface from one "screen" to the next. The screens themselves could be
panels or components (part of the whole app, or the entire app itself). While I'd
been writing much of this code myself, to do these animations, it just got really
tedious and frustrating to add this level of complexity to my code, when all I needed
were some simple animations. I've been using the SwingX API and the TimingFramework
API to perform the animations and leverage the components, however, this last piece
was missing. And this last piece just got delivered by Chet Haase, as a part of
the binary deliverables with his (and Romain Guy's) great book - Filthy Rich Clients.

I needed to perform animations in the desktop app framework that I'm building

components around on the screen, and other animations that pop up components
on top of existing components, etc. After creating a few of these effects,
I realized that I was doing the same thing over and over again, which is why
I decided to write this tutorial to encapsulate this pattern, in the hopes
that I will help others doing the same thing.

If you've ever want to incorporate web services into your graphical
applications / applets / widgets written in Java, then there are some
threading issues that you have to be mindful of, and design around. This tutorial will guide
you though some of the important threading issues you have to keep in mind when building
such applications. The strategies outlined in this tutorial apply to accessing more than
just web services from Swing apps; it also applies to loading information from databases,
and performing any other kind of time consuming process that has to happen in the desktop
app and interact with it, but can't make the user interface unresponsive.

In this tutorial, we will create an XML document, the contents of which can be accessed using a
JFC/Swing application and from a web browser (via a Servlet). The XML document is a very
simplistic representation of an address book which stores the name, email and company name of
people. The XML document is written manually, and its structure is known by the Swing application
and the Servlet.
