MinGW - Minimalist GNU for Windows
This is the official download site for the latest packages originating from the MinGW.OSDN Project , (formerly the MinGW.org Project; however, that domain is no longer associated with this project). MinGW is 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. Although (currently) offering only a 32-bit compiler suite, all of MinGW's software will execute on the 64bit Windows platforms. MinGW is a registered trademark of Software in the Public Interest Inc. , registration number 86017856 ; this trademark has been registered on behalf of the MinGW.OSDN Project , and its use by any other project is unauthorized.
Properties Editor
This editor can directly edit property files written in Unicode reference characters, eliminating the need to convert to Unicode. In addition to the usual editor functions, it can also be used as an Eclipse plug-in.
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. 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.

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!

OSDN.net is Ending Ad Banners and Starting New File Synchronization Feature with GitHub
2020-04-27 07:01: We are proud to announce two major changes on OSDN.net. First, OSDN Division of Appirits Inc. has decided to put an overall end to ad banners that profit the OSDN.net administrator side. Also coming soon is a new synchronization feature with GitHub for File Release and Storage. Background In 2000 when the antecedent organization of OSDN was founded, there were three "D" s that were deemed inevitable for the open-source community to work on open-source development: Develop, Distribute, and Discuss. OSDN laid down a basic policy whose aim was to engage in activities to support the three "D"s. It has been over 20 years since then, and the environment surrounding open source has continued to change dramatically. Nonetheless, those three "D"s still remain to be important to the community even now. OSDN offers features that support the three "D"s to all the open-source-loving communities for free, and it is our essential policy to carry on with our commitment to support these activities. OSDN's activities of the last twenty years were supported by the revenues generated from the ad banners posted on OSDN.net. However, having seen problems after problems of inappropriate and fraudulent advertisements that occurred on our former partner site in the US, and being faced with the excessive evolution of AdTech, it is becoming more and more unavoidable to take actions to ensure privacy protection. It is also true that the ad banners that occupy so much of the space are making it difficult for us to provide ideal UX and UI. Even after our brand name was changed in 2015, OSDN.net has continued its steady and stable growth. Last month, OSDN.net recorded its highest number of unique users. Yet, Appirits Inc., who recognizes open-source technologies as the foundation of its business, figured that by making OSDN.net free of ad banners which profited the company, Appirits can exhibit its supportive stance toward the open-source community, and it is more important to further foster the growth and development of OSDN.net. Schedule for No More Ad Banners For about half of all the OSDN.net pages, ad banners will be removed immediately, which is scheduled to happen at the end of May. However, there are exceptions of some download pages (pages where downloading of files take place) that are allowed to continue posting ads. Please note that ad banners will continue to appear on OSDN Magazine for some time. Financial Support Offered to Open Source Projects Now here is the reason why there are exceptions to the no more ad policy. We have been offering financial support to some of the open-source projects as a part of our activities, and so we will continue to allow these projects to post ad banners only on their download pages. All the revenues that are generated from the ads posted on these pages will go to the open-source project side. Moreover, for projects whose scale has reached a certain standard, we are planning to create a mechanism that enables open-source projects to post ad banners or donation guide on their own. Synchronization Feature with GitHub for File Release and File Storage In May 2020, we are introducing a new sync feature with GitHub for File Release and File Storage. This new feature enables the target Release/Tag in the GitHub repository to be automatically synchronized to OSDN.net, and it is available for both File Release and File Storage. This allows users to simultaneously release software via OSDN.net global mirror network when there’s a new release on GitHub. - For File Release Feature: (Scheduled to) Start offering Beta on May 7, 2020. - For File Storage Feature: Start offering Beta in May 2020. (The exact timing will be decided after having examined the new feature on File Release.) Under the circumstances in which the novel coronavirus continues to spread around the world, Appirits recognizes that there are more and more roles that open source can and should play, and we will continue to commit ourselves to the growth and development of OSDN.net and support infrastructures dedicated to the open-source community. -- Shuji Sado General Manager of OSDN Div., Appirits Inc.
Starting the Global Version of OSDN Magazine
2020-02-26 14:19: We have set up a new column called OSDN Magazine, which delivers open-source related news. In the side header, there is a tab called Magazine, which you may have already notice. You will see some news articles there. We originally translated some open-source related news sites, like NewsForge and Linux.com, into a Japanese, and we ran a website centered on them. Still to this day, we run the website, which is called OSDN Magazine. Having such background, OSDN Magazine had been a website that only supports Japanese, but now we are determined to gradually globalize it. Currently, there are only few articles, but our plan is to offer more and more contents besides news articles in the future. OSDN Magazine https://osdn.net/mag/
