OK, here is what I dont get:
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."
How do you explain that?

The speed of light is always 186,000 mps regardless of where you are relative to another observer. The spectrum of the observed light appears shifted one way or the other; the speed remains the same.
This is no different to Doppler's train travelling at 60mph and all observers agree that that is the speed regardless of the pitch of the sound they hear at any given point on the train's path.

More like 300,000,000 ms^-1

It is the distortion of time with speed that is the head f***. Doppler shift doesnt come close IMO.

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.

Maybe a NAS?

Create a Mac VM environment? I was trying to build one recently[^] but it did not work out.
Maybe things will be better with a SSD.

I made a home server a few years ago when faced with the same conundrum. It has since Frankensteined into a full blown Plex Media server, but it all started from humble beginnings.

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):

Unix/Linux does consider unlimited temp directory as security flaw (as temp is accessible to every application) and limits it size... It also clears it on every boot (configurable) in most distros...
This also has (or had) some security flaws, but interesting the different approach to temp folder...

Alex: Fix it? How you gonna fix this?

Interesting, but I am sure the issue of ever growing temporary internet files is a bug that will eventually get squashed by Microsoft - I hope

Certainly the fetch mode just doesn't matter any more with SSDs - further, make sure you turn off indexing. As for the pagefile, it depends on how much RAM you have.

Thanks for the input.
32GB of RAM - Plenty.

Superfetch is one of the first item that should be disabled when you go SSD,
even on HDD these days it's value is little to none
1. what ms defaults into superfetch includes rarely used items such as wordpad,
2. the check to if it's cached the latest/updated in which time the performance of random seeks to compare the file/directory info vs sequential reading the source item on today's optimised HDD's also almost completely mitigates any time saving.
3. Loading rarely used items and then later swapping them out when you load some monster like vs (which for some reason is often not, or only small parts thereof, cached into the superfetch makes it an even more useless artefact of days past.

BTW, does the browser not have the option to remove it's temp files on exit?

Yes it does, but it did not clear the temporary Internet files for some reason. Either that, or it is also possible that the Windows Disk Cleanup utility simply reported an incorrect number of files remaining. As you can see from the thread I quoted in my initial post, my problem was in no way exceptional. Many other users had the same complaint.

The pagefile has been useless on the desktop for over a decade. Maybe for some niche workloads.
By the way I cleared my "old windows installations" after the Fall Update, that gave me back 35GB. On a 250GB disk, so that's a lot. So much that IMO it was really unacceptable to steal all of that space in the first place.

My Fall Update was a clean install on a re-partitioned SSD. No old Windows remnants to worry about.
