ββToday guys from CleverComponents have published a new Delphi example that starts listening to an incoming connection, accepts the connection, and receives all data over the established connection. No data is sent back to the client. This functionality might be useful when you debug a Network app and want to analyze the produced TCP traffic, e.g. using Wireshark.
The program uses the TcpServerConnection socket class from the Clever Internet Suite library to start listening on the specified local port and receive TCP packets over the Network.

The program can be easily modified to send TCP response back to the connected client because the sources are available on GitHub π

ββYet another post about design patterns. If you use the patterns in your code, please check out this big article that might help you to tackle certain problems in certain situations.
I know guys who learned patters one-by-one to quickly apply them when coding. To be honest, I didn't learn design patterns so closely, but used some of them, such as Singleton and Visitor. In fact, they was helped me a lot.
The article covers, I think, the most of possible design patterns and provides good code examples.
The examples are not in Delphi, but in fact, they allow to catch the main idea of the pattern.
Put π if the article was useful for you.

ββHello, please take a look on a simple Delphi project to learn the TLS handshake implementation using OpenSSL 3.0 Memory BIOs.
This project represents my experience in implementing the in-memory TLS handshake using OpenSSL 3.0. There are lots of examples with previous versions of the library on the Internet. So I decided to share this project to help other developers to get started with OpenSSL memory BIOs in Delphi. The main our task was to implement a cross-platform version of our Delphi components. Currently the components use Microsoft Schannel and CryptoAPI to implement TLS and other crypthographic features.
I worked with MS Schannel, SSPI, and CryptoAPI for many years and familiar with many tricks, problems, and use-cases. But OpenSSL become a real challenge for me π²
I'm still working on this test project. So if you find any errors or have questions, do not hesitate to contact me.
Also, please feel free to βοΈ the repo to help other devs to find this project!

ββGenerics, generics... recently I've read one old but actual Marco Cantu's blogpost. Generic vs. Traditional Collections. Which ones to use?
Generics allow you to prevent typecasting in your code. But Marco discusses two basic reasons not to use generics.
I know at least one more reason not to use them - when your code needs to support old Delphi versions, e.g. D7.
And what is your opinion? Please share your experience π
