MinGW - Minimalist GNU for Windows
MinGW: A native Windows port of the GNU Compiler Collection (GCC), with freely distributable import libraries and header files for building native Windows applications; includes extensions to the MSVC runtime to support C99 functionality. All of MinGW's software will execute on the 64bit Windows platforms.
CrystalDiskInfo
CrystalDisklnfo is disk utility that supports some types of USB connections, Intel RAID, and NVMe. If anything abnormal is detected, it will notify you by text or voice message, and it supports both HDD and SSD. In addition to information like model number, volume, buffer size, it obtains S.M.A.R.T. information such as how many times the power was turned on, the time length of use, and temperature to monitor the state of the disk. Important Notice Both CrystalDiskInfo and CrystalDiskMark are open source software personally developed by me. Any software development demands huge amount of time and effort, and on top of that, new hardware devices are released one after another which becomes a necessity to purchase in order to support them. Therefore, this project needs more development funds. As to current status, this project is extremely short of funds and is in desperate need of your donations. If you want to contribute to supporting the continuance of this project, please make donations by Paypal . Please make the amount of each contribution $10 USD or more (in JPYen, 1000Yen or more) if possible. Your contributions will be deeply appreciated.

CrystalDiskMark
CrystalDiskMark is benchmark software that measures the transfer speed of media data storage drive such as HD, SSD, USB memory, SD card and NAS.

Anak Krakatoa Delphi Framework
This is not just another suite of libraries for Delphi, its goal is much more comprehensive and audacious. With a library of functions, components and experts focused on practicality and versatility, "Krakatoa" (KRK) aims to change the way you program in Delphi for the better! KRK's key points are utilities functions, "Helper" Classes, Experts for creating standard units and miscellaneous components. Some of these components are Open Source and are installed together with KRK, such as ZeosLib and ICS, and are extensively used by many other Framwork components and functions. The idea is to add only really useful components. Anak Krakatoa Delphi Framework You know what it can do...
User Control (DXCE)
User Control (Delphi Experts Consortium Edition) The purpose of this User Control distribution is to unify all available versions in order to become THE definitive distribution of this, which is an excellent component for managing users. We understand that these components were developed by other people initially and credit for any and all development until revision 1 (initial) of this distribution should be given to the pioneers. All development from revision 2 will be customizations and bugfixes from various authorships. The motivation to perform this work lies in the fact that currently the original UserControl source ( https://sourceforge.net/projects/usercontrol) does not seem to contain any significant updates for some time and the existing files do not seem to follow any logic order, which makes the use of the component in large projects a risk for most developers. Features Easy initial setup from the integrated component editor Better organization of main component properties It has integrated internal messaging system that allows communication between registered users and now with the possibility of sending important message (priority) and return receipts Sends emails to users when their information is changed (password, name, profile, etc.) Full and correct use of the SGDBs it supports, with real date / time fields, primary keys, sequences and auto-increments Use of configurable multiple hashes, in order to give greater security to the application Possibility of configuring how internal messages are automatically displayed after logon, and can even be configured not to display messages automatically Application lock function. Only those who have blocked can unlock the application or terminate it Donation This is and always will be an Open Source project. However I would be grateful if you could contribute any amount clicking here
