Libjpeg 9 improves lossless JPEG compression

The Independent JPEG Group (IJG) at the German Institute for Applied Informatics (InfAI) has released a new version of the libjpeg library. The developers say it can compress photos in JPEG format in a lossless way and, apparently, libjpeg 9 outputs lossless JPEG files that are smaller than the equivalent PNG file of the same image

One of the major advantages of free software is that the community protects users from malicious software. Now Ubuntu GNU/Linux has become a counterexample. What should we do?
...
Ubuntu, a widely used and influential GNU/Linux distribution, has installed surveillance code. When the user searches her own local files for a string using the Ubuntu desktop, Ubuntu sends that string to one of Canonical's servers. (Canonical is the company that develops Ubuntu.)
...
Ubuntu uses the information about searches to show the user ads to buy various things from Amazon. Amazon commits many wrongs (see http://stallman.org/amazon.html); by promoting Amazon, Canonical contributes to them. However, the ads are not the core of the problem. The main issue is the spying. Canonical says it does not tell Amazon who searched for what. However, it is just as bad for Canonical to collect your personal information as it would have been for Amazon to collect it.
...
Ubuntu allows users to switch the surveillance off. Clearly Canonical thinks that many Ubuntu users will leave this setting in the default state (on). And many may do so, because it doesn't occur to them to try to do anything about it. Thus, the existence of that switch does not make the surveillance feature ok.

If you ever recommend or redistribute GNU/Linux, please remove Ubuntu from the distros you recommend or redistribute. If its practice of installing and recommending nonfree software didn't convince you to stop, let this convince you. In your install fests, in your Software Freedom Day events, in your FLISOL events, don't install or recommend Ubuntu. Instead, tell people that Ubuntu is shunned for spying.
