First, of course, Happy Martin Luther King, Jr Day to everyone!  If you haven’t read it lately, I highly recommend your re-reading the “I Have A Dream…” speech.  I believe it’s one of the top 10 speeches in American history.  As a Christian, I revel in the fact that we have a national holiday for minister who’s stated purpose in life was service to others.  That’s saying something as I also firmly believe in the separation of Church and State.
Exercise:
Went out for 35 minutes tonight.  Not really a jog, not really a walk, more of a shuffle-step.  It felt good to almost slow-jog.  (Remembering that last weekend I was in the ER for my heart makes that a whole lot easier to accept.   Pride goes before the heart attack!)  Anyway, I reckon I did between a mile and a half and a mile and three-quarters.   No pain.  No shortness of breath.  No chest tightness.  I didn’t feel “right” last night, so I skipped the walk.  I’m trying to err on the side of safety, if I have to err at all.
How I spent today:
Mostly, as you can tell from viewing today’s post, I spent the day just adding quotes to the blog.  I started a book about the lives of 15 of the greatest names in the field of Computer Science so I had a lot of little quotes to add.  The book (“Out Of Their Minds” by Dennis Shasha and Cathy Lazere) is excellent so far and I’ll be shocked if I don’t end up highly recommending it when I complete it and do the review.  I’m continuously amazed that most of the great discoveries / inventions / algorithms  have been made / created during my lifetime.  I went to get some blood taken for my cardiologist appointment tomorrow.  I also finished unpacking the last of my suitcases from the aborted trip to Baltimore.
Finally, I went through some photos and I have a bunch to add to the site.  Unfortunately, there is just so little time…  As a taste, here’s a photo of Hil’s mum with her mum (Hil’s maternal nana):

We all know that if you want to make something big, you have to compose it out of components — modules of some sort. You must be able to isolate parts. . . . It’s well known from programming, that this is not just a matter of division of labor because if you choose the wrong interface or an inappropriate one, the work explodes by a factor of ten — it’s not just a sum.
— Edsger W. Dijkstra
[Dijkstra doesn’t mention a “great” programmer is 10 times more productive (BY ANY MEASURE) than a “good” programmer, and good programmers can be 5 to 10 times more productive than “average” programmers. — KMAB]

…Roughly 40 percent of all software projects are canceled.  About 70 percent of the rest are late.
  –-  Dennis Shasha and Cathy Lazere
Quoted from:  “Out Of Their Minds
[This means only 18 out of every 100 software projects are on time.  Note, the authors do NOT offer a number for how many of those “on time projects” are on or under budget.  This underscores the risk of software development.  —  KMAB]

They had no sense of the significance of what was there — there was no tradition.  We didn’t do a good job preparing them.
Even if we had done a good job of preparing them, businessmen are more like engineers than like scientists.  They [businessmen] want to do more than understand.  At some point with new phenomena, you [scientists] have to spend some time understanding it, not just worrying about what are we [businessmen] going to do with it.
  —  Alan C. Kay
[This was Kay’s explanation for why Xerox failed to dominate the personal computer market even though the Xerox Palo Alto Research Center (PARC) had a windows based, mouse-driven PC and demonstrated it to Steve Jobs and Jeff Raskin (from Apple Computer, Inc) several years before Apple came out with the Mac.  —  KMAB]

Progress in using logic to express facts about the world has always been slow.  …I think that we humans find it difficult to formulate many facts about our thought processes that are apparent when suggested.

One of the primary virtues of commonsense reasoning is its resiliency.  It adapts well when confronted with new facts about a situation.
  -–  Dennis Shasha and Cathy Lazere
Quoted from:  “Out Of Their Minds
[The problem is too few people have developed commonsense and many of those who have don’t believe their eyes when confronted with new facts. (See In Broken Images)   —  KMAB]
