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.
CrystalDiskInfo
CrystalDiskInfo is a HDD/SSD utility software which supports S.M.A.R.T and a part of USB-HDD. 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.
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!
CrystalDiskMark
CrystalDiskMark is a disk benchmark software. 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.

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'.

Site announcement

Virus Detection Feature on Project File Release
2018-06-26 05:01: System side will now perform Virus scan for files that are uploaded on project's file release. Scan result will be shown on the pages of a release list and such. For virus scanning, VirusTotal ( https://www.virustotal.com/) is used. VirusTotal checks for viruses by using multiple Virus detection engines in aggregated manner. Among these engines, there are a few very sensitive ones that frequently send false positives . Therefore, in rare occasions, virus warning message may appear against a practically and absolutely safe file. (Thus, even with the scan result from VirusTotal, the file cannot be immediately determined as dangerous.) Please review the detailed result to judge its safety. Also, this feature does not guarantee that a file is free of Virus infection, with its scan result. When there are a certain number of warnings as a result of detecting viruses, the result will be notified to the administer of the file project and the person in charge of the file release, by email. (Because a recheck may be performed after a certain period of time, there are cases that you may receive multiple notifications for a single file. ) If a file is judged to have a problem, the site admin side may make necessary measures such as making it private or deleting it. Due to the size limit on VirusTotal's API, virus scan for files that are over 350MB cannot be performed. Scan result will not be displayed immediately after the upload. (Due to the behavior of the VirusTotal, and the API's access limit, it will take at least 30 minutes, and there are even cases that could take a few days.)
Support importing SSH key from GitHub
2018-06-19 10:10: Now, by simple operation, you can import your SSH key disclosed on GitHub as your OSDN account’s SSH key. To add SSH key, you can conduct the SSH key settings from your account as usual. To import SSH key from GitHub, enter your GitHub account name in the SSH key’s additional modal window and then click the button to execute. It will be imported to the textarea reserved for entering SSH key, so confirm to add. During the login using your GitHub account, the account name will be automatically complemented.
Support Login with GitHub Account
2018-06-19 10:08: Now you can login to your OSDN account using GitHub account. The registered email address for both GitHub and OSDN accounts has to be the same. If there is no corresponding account, an OSDN account will be created.
New On Subversion Feature, Option Settings that allow Modification of Revision Properties
2018-05-10 13:44: On Subversion Feature, we have added the option settings that allow modification of revision properties. If you allow modification of revision properties, project members then will be able to revise and change commit related data, such as commit message, date, and author, after the submission of the commit. This option will be quite useful when you want to revise a commit message afterward or want to move a Subversion repository from another site by using a tool such as svnsync.
New on Forum: Ability to Make Thread Sticky and More Options on Restricting Comments
2018-04-25 07:02: Sticky Posts Threads in a forum are laid out sequentially with the latest at the top, but now there's a new feature to make a part of them stick at the top. Only your forum manager or project admin is granted the right to change the settings for sticky threads. You can choose to make each thread sticky while creating one or afterwards. We offer three priority levels, from which you can choose to add to each thread. Threads with higher priority goes at the top. When there are multiple threads with the same level of priority, the latest are displayed at the top. Restrictions on Thread Comments Formerly, there wasn’t much you could do with regulating comments, besides whether to allow anonymous users to post a comment or not. But now, you can be more specific with whom you allow to post for every new thread. Only forum manager or project admin is granted the right to change the settings for restrictions on thread comments. When the settings are left untouched, the behavior of the entire forum will be based on whether to allow anonymous users to post or allow logged-in users only. The restrictions that you can set for each thread are as follows. Anyone can make a post. (Even when forum settings prohibit anonymous users from making a post, anonymous users will be able to make a post.) Only logged-in users can make a post. (Even when forum settings allow anonymous users to make a post, anonymous users won’t be able to make a post.) Only project members can make a post.
