The Count of Monte Cristo by Alexandre Dumas

The Count of Monte Cristo by Alexandre Dumas

Liked it. Long. Strong and profound Ending.

He who has felt the deepest grief is best able to experience
supreme happiness. We must have felt what it is to die, Morrel, that
we may appreciate the enjoyment of living.
    "Live, then, and be happy, beloved children of my heart, and
never forget that until the day when God shall deign to reveal
the future to man, all human wisdom is summed up in these two words,
'Wait and hope.'
    Your friend,
    Edmond Dantes, Count of Monte Cristo.

1998 Jeep Cherokee - donated to KCET

1998 Jeep Cherokee - donated to KCET

KCET's website has a "donate your car" link. Called the phone number.

Had to have my pink slip (certificate of title). Scheduled a pick-up date and time window.

So, last week the tow truck came. Had to fill-out, sign, and thumb-print all the paper work, and then they towed it away.

Hopefully this modest contribution will do KCET some good.

Debian 9 stable == > Debian 10 stable installation

Debian 9 stable == > Debian 10 stable installation

Steps were identical for when I did the Debian 8 stable == > Debian 9 stable installation.

Only differences were that sudo was already installed by default, so I did not have to have aptitude install it.

EDIT 2019-10-19

For my current Debian PC, which is a vintage Gateway laptop. I did have to update sources.list to include nonfree, as the laptop needed the i915 firmware to be installed.

Then had to do

robert@pip2:/tmp$ sudo aptitude update
robert@pip2:/tmp$ sudo aptitude safe-upgrade
robert@pip2:/tmp$ sudo aptitude install firmware-misc-nonfree

Then just to be safe, sync'd and rebooted

robert@pip2:/tmp$ sync
robert@pip2:/tmp$ sudo /sbin/shutdown -h now

2011 Honda Pilot - Automatic Transmission Fluid ATF change

2011 Honda Pilot - ATF fluid change

3.5qts DW-1 Honda ATF

Odometer was at 108,465miles

EDIT 2019-08-18

After putting in the 3.5q of ATF and doing a small drive, upon checking the ATF dipstick, the fluid level was below the two dots. Added another 1/2quart of ATF, for 4qts total, for this change. Guessing the car is starting to leak some ATF from seals and such, as the car ages.

Cleaning grease build-up on kitchen hood exhaust fan filters - baking soda solution

Cleaning grease build-up on kitchen hood exhaust fan filters - baking soda solution

About twice a year, the kitchen stove exhaust fan grease filters get clogged with greasy "gunk"

I used to try to just use dish soap and a dish brush, but the brush would just load up with the gunk, and not really remove it from the filters well, and now the brush would likely be thrown out.

So, I did some searches, and a few DIY folks said to combine baking soda with dish soap and hot water, then soak the filters in that solution.

I was skeptical, but tried it. It works!

In a large plastic tray, large enough to cover a filter with about half an inch of water, put enough water to cover the grease filter completely. Hot water works best.

Add about 1/4 cup of baking soda to the water. Stir to dissolve.

Add a tablespoon or two of dish soap to the water. Stir to mix in.

Place the greasy gunky filter into the solution, such that it is immersed completely.

Soak the filter in the solution for one hour.

After the hour has elapsed, you should see the water darkened with grease particles. Some of the gunk may float to the surface. Some of the gunk may drop to the bottom of the container.

Using a dish brush, with light effort rub all over the outside of the grease filter. The idea is just to knock loose the grease residue that has been chemically "attacked."

Rinse the filter with fresh water, then inspect. If still too gunky, discard the now-dirty soak liquid, make a fresh batch, and put the filter in.

Do as many one hour cycles of soak, brush, rinse, inspect, until the grease filters are clean enough.

At the end of the last cycle, rinse the filter(s) with fresh water very well, to remove any soak liquid. Then dry and reinstall.

SETI - low hanging fruit next-step idea - active broadcast

SETI - low hanging fruit next-step idea - active broadcast

I would like to see SETI receive funding and infrastructure to begin actively sending radio transmission broadcasts to candidate star systems, in the hopes of receiving a response.

It seems a low-hanging fruit next step. To try to determine if there are other civilizations out there, that are at or above our level of technological advancement.

It seems it would not be very expensive. I few tens of millions of dollars per year, globally, to "rent" time of radio telescopes that can support being used for broadcasting.

Perhaps, like in the book "Contact" by Segan, the message would simply be continuous wave pulses of counts. Perhaps prime numbers 1, 2, 3, 5, ..., 11. Each pulse one second long, two-seconds between counts. Then recycled.

Ideally science would have a best-guess on radio frequency to use. And have enough participation so that the broadcast power of the signal had a chance to be strong enough to be detected in the target system. And have as many participating transmitters beam to a candidate system for perhaps a week, then move to the next candidate, etc.

Of course, once there had been enough elapsed time for the system to receive the signal and perhaps transmit something back, the 2nd Phase would be to begin surveillance of the systems transmitted to, for a response, after enough years had passed.

It's still a desire, that in my lifetime, that we would discover proof we are not alone in the cosmos.

Debian 8 stable == > Debian 9 stable installation

Debian 8 stable == > Debian 9 stable installation

Went to the Debian website. Downloaded the Debian 9 netinst ISO file

Installed the ISO file to a recordable CDROM using brasero

Moved my PC closer to my internet connection. Connected it to the internet using an ethernet cable.

This PC, a Gateway laptop, doesn't have a wifi driver that will allow wifi installation. So it is a two-step process: 1. install via ethernet cable. 2. Install wifi (b43) driver.

Put the netinst CDROM in the CD drive of the PC. Rebooted.

Followed the prompts. Did a default Debian install, kept it simple. A single partition for all the folders (it's a laptop).

...after about two hours...



Installed aptitude.

Installed sudo.

  • as root ran addgroup myUserName sudo
  • *** you have to reboot before myUserName can run sudo commands ***

Installed the b43 wifi driver

  • as root, updated the /etc/apt/sources.list file to include contrib
  • as root, ran aptitude update
  • as root, ran aptitude install firmware-b43-installer
