keep alive

When I copied tens of thousands of files from one laptop to another over
the local network, they kept each other alive for the many hours it took.

Then I reimaged the bad laptop from 1803 to 1809 and now, while I'm USING
those files across the network to set up Windows 1809, the good laptop
keeps falling asleep every hour.

Even as I'm connected to those backup files across the network.

I tried just now a forever ping on the good laptop to keep it alive but
what happened was "General failure" on the good laptop "ping -t google.com"
command window when the good laptop fell asleep.

I can change the power configuration but I thought that a forever ping
would easily keep the good laptop alive.

Is there a basic command that we can run that keeps the good laptop alive
even if the power settings tell it to go to sleep?

Playing a movie will keep it awake.

The movie player must be the type that asserts
that condition to the OS.

Then the OS won't go to sleep due to HID inactivity.

As for a movie, you could make a "sound track only" movie
with no picture, then use a good compressor for the audio.
That would take up a small amount of space. Using Audacity
you could make a 400Hz tone as the sound track for the
movie, then convert it to the compressed format.

Think of the fun you can have.

You could use the Power controls but where would the
fun be in that ?

*******

You could even have found a way to move the source
file system to the destination, as an "image" and then
done the transfer locally on the destination device.
You can mount various storage formats on a Win10 platform.
It really depends on how burly and well equipped the
destination laptop is, whether this method would be
"fun" or not. Even a USB3 port on the destination laptop,
opens a world of fun possibilities for doing stuff.
Unfortunately, my laptop is one of those all-too-available
USB2 ones. And with no laptops getting ExpressCard slots,
a lot of neat ideas were prevented from happening through
that slot too. Some people get a gadget to replace
the optical drive with a 2.5" SATA bay, which opens
up some fun again. On some laptops like mine, the SATA
port is the best I/O they've got.

In a ton of experiments I've done, adhoc sneakernet
hardly ever pays off. But that won't stop me from
trying it anyway :-)

I fell asleep one night and when I woke up, that movie was playing.

Very little plot.

I think it would be fun to see how small of
a "valid" movie you could make, that could
keep a movie player running. I mean, silence
should compress pretty good, but you won't
know that until you try it out.

Here's an example of a first cut.

E:\FFMPEG\bin ffmpeg -f lavfi -i anullsrc=r=44100:cl=stereo -c:a libvorbis -t 86400 D:\quiet.mkv

24 hour "movie", size of 26,359,253 bytes.

You could improve on my result, by setting audio to 11000Hz and mono.

The movie is supposed to play for 24 hours, but various players
won't allow that.

It took maybe 40 minutes for the ffmpeg compression run.

The movie should play in VLC. WMP, not so much.

I tried to make a "silent" sound track in Audacity,
but man, the output sucks! I had to revert to doing
the whole thing in FFMPEG, which makes a really
silent audio signal (all zeros in uncompressed state).

*******

You can toss this into your HxD hex editor and see that
the WAV audio samples are properly zero. The time here is
set to 10 seconds, as this file won't be used for anything
except hex editor examination.

ffmpeg -f lavfi -i anullsrc=r=44100:cl=stereo -c:a pcm_s16le -t 10 D:\quiet.wav

The Audacity output had non-zero bytes in it.
I used the "silence" generator and the output was a mess.
I expect this was done on purpose (telephone silence, not
real silence).

I am so sorry that I forgot to update this pc keep alive thread.
I've found dontsleep to keep the pc awake.

I saw insomnia keep alive tools but didn't install them.
Here is the keepalive list I looked at before randomly choosing dontsleep.
