Recently, I have found a useful manual on how to install Delphi packages manually in RAD Studio IDE.
The author, Jim McKeeth, has shared some tips to compile, install, and set up third-party components in case if these components do not have own installer, even if you have only the source code for these components.
This matters to newbies in Delphi, or to those who devs end-user apps using third-party open-source libraries 👍

Do you use InnoSetup for making installations? Check out a script, which can download and install any dependency such as .NET, Visual C++ or SQL Server Express Redistributable during your application's installation process. You can even easily add your own dependencies. A really useful addon for one of the best free installer tools 🔥
The script uses the standard InnoSetup's Download wizard page. Wow, I didn't know about this feature 😲 Next, the script collects dependencies together with the direct download links, adds them to this page, and starts the downloading process.
I think, we will implement this feature in our TaskRunner installer, because this program often requires vc redistributables when installing on some old machines 👍

If you have a Logitech gaming keyboard, headset, or a mouse, you can try one interesting Delphi library, by Delphi MVP François Piette, who is known for the Internet Component Suite (ICS) 🔥
The library allows you to make illuminations on your Logitech hardware using the Logitech Gaming LED SDK. The sources for the library are available on GitHub.
My Microsoft Natural keyboard doesn't allow me to run the supplied examples. So if somebody has tried the library, please share your experience 👌

In this first 2021'th post I'd like to share one interesting GitHub project. Embarcadero Dev-C++ represents a fast, portable, simple, and free C/C++ IDE, which is made in ❤️Delphi❤️ It provides a code editor for the C/C++ programming language and uses Mingw port of GCC as its compiler.
Check out their repository. The recently released version 6.2 is available, as well 👍

Recently, I've read about GraphQL, an alternative to REST APIs:
https://medium.com/javascript-in-plain-english/stop-using-rest-for-apis-d697727ae6dd
The main difference is that in GraphQL, you get what you request, and nothing extra. This API was introduced several years ago and has implementations in different programming languages. I've tried to learn, what about Delphi:
https://graphql.org/code/#language-support
It seems, the standard REST Client Library cannot be used directly to send GraphQL queries. We have to use HTTPClient, or any to communicate via GraphQL, as it's made in the following simple GitHub project: https://github.com/bogdanpolak/graphql-delphi
If you know a good GraphQL implementation in Delphi, please share your experience 👍

Check out an interesting video by Marco Geuze, an Embarcadero MVP and the co-owner of GDK Software.
The video describes how to write code that is easy to understand and easy to change. This is especially important, if you are working on a project and your client comes back with some changes.
There are lots of examples and use cases, which I think, may be useful to even experienced devs 👍

When developing a program, which works with DB, the main headache to me is to optimize SQL queries.🧐
Recently, I've read one interesting article, where the author describes how to improve the query execution performance, find and create missing indices, and discusses some performance tuning techniques.
If your project utilizes SQL Server, MYSQL, or PostgreSQL as a data storage, this article may be helpful for you 👌
