NonCompressibleFiles
Create test files which can't be compressed

NonCompressibleFiles is a benchmarking aid which creates test files that either can't be compressed (feed them into an archiving program and they won't be reduced in size), or have the maximum possible compression level.

This is particularly useful when you want to measure data transfer speeds. You could just select a random group of files from your own hard drive, but if the data stream is compressed then that won't give you an accurate figure. Transferring 10MB of JPEGs will probably take much longer than transferring 10MB of TXT files, for instance, simply because they can't be compressed to the same degree.

Launch NonCompressibleFiles, though, and you're able to produce as many "non compressible files" as you like. Just enter values in the "Number of files" and "Size of files" boxes, click Start, and wait as they're created.

The end result is a set of files which really can't be compressed. In fact, when we put ours through 7Zip they were 1.29% larger than the originals. And so, if you use them in a data storage or transfer test, you can be very sure that compression isn't going to have any significant effect on the results.

As a bonus, NonCompressibleFiles is able to produce files with the maximum possible compression. It works, too; 7Zip reduced our 1GB of test files to a mere 152KB. There probably aren't as many testing applications for these, but the option is available if you need it.

Version 2.44:
    - Verification and testing of Non-Compressible-Files on Windows 10 Technical Preview.

Verdict:

It's not a program you'll use every day, but if you regularly benchmark hardware or software then NonCompressibleFiles could be occasionally helpful.

WhatsApp Messenger 2.12.5

Free Full Commercial Software

WhatsApp Messenger is the world's most popular instant messaging app for smartphones.

You can use it to send and receive text and voice messages, photos, videos, even call your friends in other countries, and because it uses your phone's internet connection it might not cost you anything at all (depending on whether you'll pay data charges).

It's easy to set up and use. There's no need to create and remember new account names or pins because it works with your phone number, and uses your regular address book to find and connect you with friends who use WhatsApp already.

You can talk one-to-one or in group chats, and because you're always logged in there's no way to miss messages. Even if your phone is turned off, WhatsApp will save your messages and display them as soon as you're back online.

There's plenty more (location sharing, contact exchange, message broadcasting) and the app is free for a year, currently $0.99/ year afterwards.

Version 2.12.5 brings:

• Per chat custom notification settings and mute
• You can now include videos in your chat backups in Settings > Chats and Calls > Chat Backup
• Mark chats as unread or read with a swipe to the right
• Better support for VoiceOver
• Directly share contacts from the Contacts app and locations from Apple Maps to WhatsApp
• Lower the data usage used during WhatsApp calls in Settings > Chats and Calls 
• Earlier messages now load automatically as you scroll chats
• Improved design for cropping photos and videos
• Location messages now use a large map thumbnail
