Training

It’s been a while since I did any decent runs, and today being a good sunny day I decided to go for it.

And shocked by how bad I was 😦

 

I was following Fitbit’s workout which was 2x 12 minute jogs separated by a 90 min rest, then a 3 minute run at the end with a cooldown at the end of the workout. I stopped several times during the runs which annoyed me.

Got the two 12 minute runs down but didn’t do the three minute run at the end.

New Ubuntu Quirks

So, I install Ubuntu 17 clean on my laptop after the issues I had with drivers and immediately found out that gksu was not installed.

Installed that and tried to

gksudo nautilus

That failed and found out that Wayland had replaced the default of Xorg. Found an old Xauthority file from my backups and copied that back, which allowed me to get the popup window back for my gksu, but I couldn’t click it to enter the password 😦

Then I found this article:

https://www.linuxuprising.com/2018/04/gksu-removed-from-ubuntu-heres.html

Which tells me I need to use the admin:/// file prefix instead to open something up as admin. Guess I’ll give it a go later.

Upgrading Ubuntu (fun! ¬_¬)

Spent several hours trying to upgrade my Ubuntu installation from 15 up to the latest 17. The upgrade didn’t fail, but I did see a few error messages, and now I have applications failing to start for various reasons, including the settings applet; and when I install or use my nvidia drivers, ubuntu doesn’t start up properly until I do


apt-get purge nvidia*

But removing all the nvidia stuff causes it to fallback to nouveau which for the most part works, but not exactly good for any linux gaming.

Looks like it’s going to be a full-reinstall job to make sure everything is clean 😦

Random Thought…

There’s a thought experiment known as Theseus’s paradox (and a couple of variants) and it goes something like this.

If you have a raft and replace the oars and planks due to them rotting or being old, or similar, to such a level that the entire raft is eventually replaced, is it still the same ship?

If you inherited an axe from your uncle and you replace the axe head because it’s blunt, and then the wooden handle because it broke — is that axe still the same one you inherited? Can you still call it your uncle’s axe?

Similarly, if all parts of a computer program are replaced by patches/hotfixes (not as full releases), is it still the same program? Can you, for example, call Microsoft Excel V1 a V1 if every part of it has been replaced with new code through patches and hotfixes? Can you even call it Microsoft Excel?
