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
CrystalDiskInfo is a HDD/SSD utility software which supports S.M.A.R.T. and a part of USB, RAID and NVMe. 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.
FFFTP
FFFTP is lightweight FTP client software. FFFTP has many useful feature such as directory mirroring, character encdoging conversion, Firewall and SOCK, one-time password support, and so on.
TortoiseSVN
TortoiseSVN is a Subversion (SVN) client, implemented as a windows shell extension. Which means it's available right where you need it: in the Windows file explorer. It's intuitive and easy to use, since it doesn't require the Subversion command line client to run. Simply the coolest Interface to (Sub)Version Control!
Manjaro Linux
Manjaro is a user-friendly Linux distribution based on the independently developed Arch operating system. Within the Linux community, Arch itself is renowned for being an exceptionally fast, powerful, and lightweight distribution that provides access to the very latest cutting edge - and bleeding edge - software. However, Arch is also aimed at more experienced or technically-minded users. As such, it is generally considered to be beyond the reach of those who lack the technical expertise (or persistence) required to use it. Developed in Austria, France, and Germany, Manjaro provides all the benefits of the Arch operating system combined with a focus on user-friendliness and accessibility. Available in both 32 and 64 bit versions, Manjaro is suitable for newcomers as well as experienced Linux users. For newcomers, a user-friendly installer is provided, and the system itself is designed to work fully 'straight out of the box'.
