The doppler effect, applied to light, causes red/blue shift. Blue shift if the object is moving away from the observer, and vice versa. So to us the uiniverse looks blue because it is all expanding. Blueshift - Wikipedia[^] "Doppler blueshift is caused by movement of a source towards the observer.
Theory of relativity: Theory of relativity - Wikipedia[^] "The speed of light in a vacuum is the same for all observers, regardless of their relative motion or of the motion of the light source."
So years ago I built a small linux box to play with ... this was before VMs and downloadable ISOs made firing up a linux (or any other machine) trivial. There it sits on my desk...
This is the Christmas break, and I traditionally target technologies I want to learn. One area is to play with "full stack" development - nothing serious - just get it up and running, etc. And it occurs to me a VM easily handles this.
Any ideas as to what I could use a small pizza box machine to do? It's a core i3 with good ram and an SSD, so it's quick. I'm drawing a blank.

perhaps have a go installing whatever software is around to turn it into one of those free tv streaming boxes?
Or that free games site somebody mentioned a couple of days back?
Or, download the bitcoin mining thing?
Is seti still running it's screensaver search-for-aliens? - do that at the same time as the bitcoin mining - become rich and be the one to learn alien techno-secrets.

For some time I have been battling to delete temporary Internet files. The Windows Disk Cleanup utility just does not work in Windows 10. The temporary Internet files just grow and grow, and I have seen users who complain online that it exceeds many Gigabytes.
I am not sure, but I believe it can be a security concern. I don't want remnants of webpages that I visit (like financial institutions) to remain on my machine forever. Apart from that it takes up disk space and bloats up systems drive images.
Then I saw several mentions of the PrivaZer utility online. I downloaded and installed it, and found it to be very powerful. It can even delete traces of you Internet activity, as well as temporary files. I ran it and the temporary files were gone.
But that is not all: I also used it to disable Hibernation Mode. That saved several GB on the systems drive. Then I set it to delete the Pagefile.sys on Windows shutdown. Another 7 GB saved. All in all my systems drive shrank by 14 Gigs.
The strange part: Subsequently I found no perceptible difference in the speed of the machine, including boot speed. Which begs the question: With a fast machine with SSD for the systems drive, do you even need Hibernation Mode and the Pagefile?
I also disabled the Superfetch service, which I think is unnecessary with a SSD drive.
Any comments from members?
This looong thread deals with the difficulty deleting Internet files (with some amusing comments directed at Microsoft in the process):
