Usually, to save a whole web page or just part of the content to our local disk, we have only two ways for choise: 1) use the browser built-in print function (Ctrl + P) to save an entire page as a PDF file; 2) copy the corresponding content and paste them into a local, new created TXT or DOC file, which requires at least 4 steps to finish: copy the text and/or image -> create a new file and name it -> open this new file -> paste the content from clipboard to file and save the file.

Sometimes because of work or other things we may need to convert the regular CSV (Comma Separated Value) format of files into Excel or other proprietary formats. In this case, I recommend you a very handy, powerful and popular CSV file editing/modifying application CSV Buddy, which is specially developed for processing large CSV files in batch.

Jitsi (AKA: Jitsi Desktop, formerly called SIP Communicator) is a powerful, scalable, secure (using the SIP/RTP/SRTP/ZRTP encryption algorithms), high-quality and community-driven VoIP/video conferencing/instant messaging application from France, written in Java. It's free, open-source, cross-platform (across Windows, Linux, Mac OS X desktop platfroms and Andrjoid, iOS mobile devices), multi-protocol and multi-user on use and allows to be made secondary development.

MKV (Matroska Multimedia Container) is an increasingly popular video format. In some cases we need to extract the resources from MKV video so as to obtain the video, audio and subtitles inside separately for other use. For example, make an audio version of a film/TV play; edit, modify, or translate the subtitles (and then use MKVToolNix to repack them all). At this time, we can use MKVExtractGUI this tiny app to solve the requirement perfectly.

Panorama (full name Easypano Panorama) gives us an immersive and realistic feeling, hence this technique is primarily used for exhibiting house buildings, scenic spots, hotels, campus landscape, and many other scenes. In real life, however, the viewing angle of photographs taken by the traditional camera is very limited. This case, to make a complete and perfect panorama, a professional image stitching software is indispensable.
