Password Issues On Ubuntu Login

I found myself unable to enter my login credentials when prompted to do
so in Ubuntu. I think I might have changed it then forget about it.
I've been running the current session for more days than I should have.
I forget. So what's the solution to my problem. How do I get in to my
system now?

It involved getting into the grub menu somehow. I am uncertain as to
how to do that exactly in your system. So there's a couple of ways to
do it (finger's crossed). When booting at system start, use the esc key
or the shift key. The first one worked for me. The timing is key. Wait
until the bios banner shows then hit the esc key once. I am using
Ubuntu 22.04.4 here. I have a current version of grub.

The grub menu will give you options and the one you want is: root. Yes
you want root privileges to set the root password. It should give you a
terminal access where you can issue commands.

Type: #mount -rw -o -s remount / ==> this command mounts the
filesystem

At this point, check how many users you have. Type this command.

# ls /home ==> gives you the names of users

If you are the only user, then I assume you use sudo to gain root
privileges. Setting your password is setting root password, so.

Type: #passwd username
#password ==> type your password, it will not show you what
you're typing (like in the movies). Then it will confirm what you
typed.

To exit the grub menu just type exit. You might also just want to
reboot the system, in which case type reboot. And that's it.

Reflections On My Blogging: Keeping It Honest

When you're facing a white, blank screen trying to decide what to write, it seemed hopeless and hopeful at the same time. It's like watching a boat with its sails unfurled but there's no wind, yet you wait and then see the tide turning. You have to stop the distractions. Shut the door. Wait until your breathing is regular and your mind relaxed, like your wrists on the table infront of you. I imagine me looking sideways but not hearing anything. The sounds come much later. I see the big mass of color first, the greens. Just the vegetation, moving, not even individual trees, not leaves, just the big green. Then behind it the blue sky, unfocused and floating. Do not concern your brain with the details. Forget the words and the punctuations. But be mindful of the flow, trace the outlines, hear the motions. Sometime these things don't have a name, give it a name. How do you give something a name and still be honest? How do you keep your writing honest? I...

Webapps in Unity

So it has been 4 months since Ubuntu 14.04 came out. This is LTS and supported for 6 years by Canonical. The first mobile device with Ubuntu pre-installed is promised to come out later this year, 2014. It's time to check out how the apps perform so far. It is a good idea. I use Gmail and Twitter and Facebook. Why not a webapp in a desktop? So I start the Twitter and Gmail webapp. So far it has crashed my computer 6 times. Not a very good sign. On the other hand it does work but not as stable as opening them in Firefox. -- Use my PGP key if you want to encrypt your replies/messages to me.
