RadBuilder is an excellent RAD (rapid application development) tool with a fully visual integrated development environment (IDE). It is primarily used to quickly create interactive multimedia applications, database applications, and Web applications for Windows, without writing any code. It is so easy to learn and use that it can be picked up quickly by beginner developers without any programming experience.

When a user is primarily receiving rather than sending emails, a simple and handy email reminder is more appropriate than an all-powerful email client for him. Because in this case, the user just needs to know when and who sent the email quickly and in a timely manner, so as to deal with the messages in time, not to delay the work, or simply not to read the insignificant emails, even spam.

If a website has a Feed/RSS function, it can tell us whether a website/webpage has been updated or not. Conversely, if some sites don't offer or turn off the RSS functionality (this has become a trend), you can use some online tools or PC software such as Website-Watcher to meet the same requirements, without having to do that manually through a web browser.

Usually, to print or save a web page as PDF document, we can use the built-in printing function provided by web browser or choose the method of taking a screenshot before printing it out instead. But either will inevitably print out the ads and some other unnecessary contents on the page, thus wasting a lot of space on page. If you often need to print or save web pages, Print Friendly & PDF is the perfect tool to save much time, effort and resource for your printing work!

Unfortunately, all characteristics of Shadowsocks (SS) and ShadowsocksR (SSR) have been fully and absolutely identified and controlled by GFW ("thanks to" the forced compromise from their developers). In short, as long as the GFW wants to block your VPS, it can now do this easily and perfectly in less than 30 seconds. If you find that your SS/SSR is still working well, that means GFW has no interest or there is no need to ban you right now. Of course, each blocking cycle of GFW is about 10 weeks. Therefore, we can roughly calculate when our VPS can be unblocked.
