​​Recently, I've heard about JSON signing and encryption library in Delphi. The library is open-source and available on GitHub. This very interesting repository also contains four articles on using JWT and JSON security in Delphi.

Wow, neither compilation hints, nor warnings πŸ”₯ The library doesn't install components in the palette. You can use it directly in your code.

Let's ⭐️ this useful project!

​​Have you ever used the transaction log backup or the copy-only backups when administering an SQL Server DB? In my practice, I only used the full and the differential backups πŸ‘€

The following article may be helpful in understanding different backup types, which are available to administer databases and recover a database in the event of a database corruption issue ☝️
https://www.red-gate.com/simple-talk/sql/backup-and-recovery/sql-server-backup-types/
Check out an interesting article, which describes different ways to compare two SQL server databases. The author uses the standard SQL Server Data Tools, dbForge Schema Compare, and SQL Server Integration Services:
https://blog.devart.com/compare-and-find-data-differences-between-two-tables-in-sql-server-with-ssis-and-dbforge-tools.html

☝️I know at least, one more easy-to-use yet power tool, Database Comparer, which allows both comparing and synchronizing the databases structures. BTW, not only for SQL Server.

​​Recently, I've read an interesting blog post about migrating from BDE/Paradox to InterBase. The author uses the CleverComponent's IBPump utility to transfer data to a new database.
Huh, we wrote this app in Delphi 6 18 yeas ago. Maybe it's time to update the app up to Delphi 10.3 Community and publish on Github?

​​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 πŸ‘
