It's more comical than that. I did a quick Google search for "college
of marin navigation program" and this appeared:
"COM Launches Navigate Platform"
<
https://www1.marin.edu/news/com-launches-navigate-platform>
That was rather oddly worded, but it might be a platform to teach
navigation. However, after reading the announcement, it turns out
that it's a program to help students navigate through course
registration ordeal process:
"College of Marin (COM) launched a new platform aimed at making the
course registration process more user-friendly"
No mention of marine navigation. My guess(tm) is that Tom searched
for a nearby school that taught how to "navigate", found this page,
and assumed that the school taught marine navigation.
The College of Marin is a community college (formerly known as a Jr
college). That means a high school diploma is required, which Tom
lacks. I now see why they need a Navigate Platform to help make
registration less confusing. I couldn't find the admission
requirements. Apparently, I need to create an account in order to
obtain this information. I gave up.
At least we now know what school Tom was referring to in:

"I read all of the books that would have gotten me a bachelors degree
and was learning the realities of the world as well. I was rather
taken aback to discover that I had a degree in ship's navigation. And
from a prestigious school in Marin County as well."
>>Too bad I lost my full resume in a computer crash.
14 pages of resume as I recall. You have 13 jobs listed on your
online resume. There's no room between the 13 jobs for any more jobs.
Perhaps it was your doppelganger (evil twin) who worked at all those
missing jobs and using your name.
>>I still wasn't back enough from my concussion to know what to do and took it to a so-called computer repair shop. They totally erased the disk and installed a new operating system. It was unnecessary to erase the D drive since the operating system that had crashed is on the C drive.
Sounds good. However, I find it odd that whenever something goes
wrong, it's always someone else's fault. I don't erase data without
the owners prior permission.
>>Somewhere on the group Liebermann was saying that most of the problems he was finding was loose metal bits and bad solder joints. Think about that for a minute. Motherboards are wave soldered at real computer manufacturers. It is nearly impossible to get a bad solder joint. So he is working on computers hand soldered in little shops likely in China.
The original quote was:
<
https://groups.google.com/g/rec.bicycles.tech/c/YAgynT7Dw2I/m/lKxG17YbAQAJ>
"Many of the computers I saw for repair had intermittent problems.
Most were loose connectors, loose wires, metal debris on the
motherboard, bad soldering, bad crimps, bad wire bonds (inside
transistors and failing components (usually electrolytic capacitors)."
Today's motherboards do not have any hand soldering. However,
laptops, AIO (all in one), SBC (single board computers) and especially
power supplies, still have some hand soldering. That's because the
larger parts (electrolytic caps, switches, connectors, heat sinks,
power xsistors, etc) have sufficient thermal mass that an IR or other
reflow heater cannot transfer enough heat to the leads for the solder
paste to melt without also melting nearby small components.
>>Also real high performance computers use multilayer boards that
>>shorten the lengths of lines between components and lessen the
>>capacitive delays.
All, and I do mean all, of today's motherboards are multilayer. Nobody
makes a computer on a single sided PCB (printed circuit board).
Shortening traces is not to reduce delays. What's done is that bus
traces are laid out in equal lengths to prevent differential skew so
that digital signals along different wires in a bus all arrive at the
same time.
>>So there is a reason to buy desktops and laptops from good
>>manufacturers like HP or Dell.
Dell is mostly good. HP is marginal. Most of what I've work with in
the last 20 years is on Dell hardware. Many reasons, but the
economical availability of repair parts and boards is quite good.
Construction quality of Dell is generally excellent.
I have two Dell Optiplex 9010 DT computers on my desk that I'm
preparing to deliver to a customer in about 10 days.
<
https://www.ebay.com/itm/185913407797>
The 9010 was released in 2010 but is still running just fine. The
only problem so far is the vendor sent me both machines with almost
dead CR2032 batteries. Total cost for each machine, including a new
Samsung EVO 870 EVO 500GB SSD, was $75/ea. Looking around my house,
most of the machines are Dell, with a few HP desktops.
>They may also have main components made in China, but they are

Everything is made in China. You get what you pay for. If you want
good computers, be prepared to pay the Chinese good money for them. If
you want the lowest selling price possible, be prepared to have the
Chinese deliver garbage.
