Troubleshooting Some Problems

I got this nebulous challenge about my webcam. It seems in Ubuntu 13.10,
the webcam decides on its own when it wants to work. I use it on my
skype calls with Mother. I also use it once or twice in Google hangouts
with friends. I downloaded cheese just to test if it works fine. It
works off and on in a span of one session. How do you figure this one out?

The unity panels crashes often or it's missing icons now and then.

The Thunderbird email application has rendering issues. Some texts goes
white and turns back on after I move over my mouse. The lightning add-on
stopped working the other day. I assumed it's Google Calendar refusing
to give it permission or it's down. I happen to find the solution to
this problem from the ubuntu forums. It seems the latest version of the
add-on doesn't work in linux. The solution is to revert to an older
version of the add-on. I had to disable the automatic update for the
add-ons unfortunately.

Equalizer plugin for Rhythmbox doesn't work for version 2.99.1. The
albumcover-browser add-on works beautifully for this version but it adds
around 100 MB of ram to Rhythmbox basic RAM grab. Ouch.

I changed major passwords this week. Tested the backup if it works. I
tested the new passwords to see if I remember them.

I upgraded Firefox to 25 last night. They fixed some bugs and added
stability in flash and java handling. Anyway it's what I can see and use
in my browsing that I'm mentioning here.

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 filesyste...

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.
