       | That PC post always irked me. Not because it showed positive

       | to teams /projects that move slowly on purpose, with intent.

           | The main issues are, in general: 1) increased regulation,
           | which includes internal self-regulation. Lots of rules that
           | are preventing potential minor problems, but have a lot of
           | overhead to follow. 2) large projects are treated like a
           | Christmas Tree. Everybody expects their vaguely adjacent
           | hobby horse to be addressed by the project... so scope keeps
           | growing. There is ALWAYS something you can point to that has
           | a good cost/benefit; and always addressing these ensures that
           | the project never actually finishes. 3) lack of decision
           | making. There is a general analysis paralysis and fear of
           | making the wrong call. It's often cheaper to just move ahead
           | and risk rework. By not moving ahead, change orders are being
           | incurred anyway.
           | 
           | As much as a hate saying it, the best thing for any large
           | project in these orgs is being run by a semi-dictator who has
           | enough political capital internal to the org, and who

       | You can compute the distance to the moon if you know the radius
       | of the earth by looking at how long lunar eclipses take, data
       | gathered over years of observations.
       | 
       | Eratosthenes computed the radius of the earth by clever
       | trigonometry in ancient times, and Aristarchus computed that a
       | 3.5-hour lunar eclipse indicates that the moon is ~61 earth radii
       | away.
       | 
       | Once you have the distance to the moon, you can compute the size
       | of the moon by measuring how long it takes the moon to rise. It
       | takes about two minutes, and so the radius of the moon is about
       | 0.0002 of the distance to the moon.
       | 
       | By cosmic coincidence, the sun and the moon appear to be
       | approximately the same size in the sky, so the ratio of
       | radius/distance is approximately the same for the sun and the
       | moon. If you measure phases of the moon, you'll find that half
       | moon is not exactly half the time between the full moon and new
       | moon. Half moon occurs not when the moon and the sun make a right
       | angle with the earth, but when the earth and the sun make a right
       | angle with the moon.
       | 
       | You can use trigonometry to measure the difference between the
       | half-time point between new/full moon, and the actual half moon,
       | giving you an angle th. The distance to the sun is equal to the
       | distance to the moon divided by sin(th).
       | 
       | To get th exactly right, you need a very precise clock, which the
       | Greeks didn't have. It turns out to be about half an hour.
       | Aristarchus guessed 6 hours, which was off by an order of
       | magnitude, but showed an important point: that the sun was much
       | larger than the earth, which was the first indication that the
       | earth revolved around the sun. (Aristarchus' peers mostly didn't
       | believe him, not simply out of prejudice, but because the
       | constellations don't seem to distort over the course of a year;
       | they were, as we now know, greatly underestimating the distance
       | to nearby stars.)
       | 
       | Next, you can compute the _shape_ of the orbits of the planets,
       | by observing which constellations the planets fall inside on
       | which dates over the course of _centuries_. Kepler used this data
       | first to show that the planetary orbits were elliptical, and to
       | show the relative size of each orbit, but with only approximate
       | measures of the distance to the sun (like the th measurement
       | above) there 's not enough precision to compute exact distances
       | between planets.
       | 
       | So, scientists observed the duration of the transit of Venus
       | across the sun from near the north pole and the south pole,
       | relied on their knowledge of the diameter of the earth, and used
       | parallax to compute the distance to Venus, and thereby got an
       | extremely precise measurement of the earth's distance to the sun,
       | the "astronomical unit." It took _decades_ to find the right
       | dates to perform this measurement.
       | 
       | The cosmic distance ladder goes on, measuring the speed of light
       | (without radar) based on our distance to the sun and the orbit of
       | Jupiter's moon Io, using radar to measure astronomical distances
       | based on the speed of light, measuring brightness and color of
       | nearby stars to get their distance, measuring the expected
       | brightness of variable stars in nearby galaxies to get their
       | distance, which provided the data to discover redshift (Hubble's

       | Well, in 1980 when I got my hands on the first "powerful"

       | project to do a little machine learning so that I would one day
       | have some of the foundation I needed to handle the data more
       | intelligently in the future.
       | 
       | That's what I always wanted to have a computer for and why I took
       | Fortran in college to begin with.
       | 
       | I knew I wasn't going to reach the "intelligence" part within a
       | short number of years, for one thing I had figured out it would
       | be much faster on a more specialized chip than a CPU, plus it
       | would require megabytes of memory when I only had kilobytes, and
       | way more storage space too.
       | 
       | I couldn't be spending years concentrating on this while waiting
       | for hardware technology to progress, and for survival otherwise I
       | gravitated to a niche within a natural science career that would
       | not be replaced by the AI which I expected to be rapidly
       | approaching from those who had a much better head start both
       | financially as well as in computer science.
       | 
       | Now by the time the late 90's rolled around, I already had my own
       | company for a number of years (knew that was going to take
       | decades too so I had started in that direction as a teenager) and
       | by then had _more than one computer_. Woo hoo!
       | 
       | And megabytes! Oh Yeah!
       | 
       | Plus Office '97 which put the "paperless office" within reach
       | even though paperwork was my primary deliverable product.
       | 
       | With Y2K looming I decided to use some of the megabytes in the
       | more powerful PC to try a bit of the old ML again, with much more
       | of a bent for AI this time. I had already been pitched in the
       | early '90's by neural net vendors but I wasn't ready for that.
       | After a few more years of consideration I had a much better idea
       | of the groundwork I would need, separated the raw automation from
       | the intelligent input I was making and that was a good milestone
       | in efficiency right there. I was barely able to get a bit of my
       | concept from 1980 put on to a "powerful" DOS/Windows platform
       | when it crashed and set me back a couple months before starting
       | to get hammered into eventual submission by years of stacked
       | natural disasters.
       | 
       | Growth had been halted but by this time I was pretty mature and
       | charge enough per page that I personally wasn't going to be the
       | one that needed any more automation than I already had. When I
       | first started I could afford to type each page manually on a
       | (intelligent) typewriter to begin with, and I could make even
       | more at today's prices now doing that again if I had too. This
       | was another marginally positive trend that was not very obvious,
       | and it was so marginal that was when I accepted that I would have
       | to actually outlive most of my contemporaries if I was going to
       | make very much of it.
       | 
       | Whew, that wasn't easy and it took a while too.
       | 
       | Even if total automation doesn't make _me_ any more than total
       | manual effort, it is the kind of thing that the bigger
       | multinational groups could really take to the bank. So I 've
       | always kept it in mind, I knew about it all along, that's where I
       | got started.
       | 
       | Anyway, there's still a blank tab on an XLS spreadsheet where the
       | tabs to the left are all the "very important" data which I
       | ruminate about then do a little typing accordingly before hitting
       | the button. Then the tabs to the right get populated sequentially
       | and filtered until the final tab spits out a file that gets
       | emailed to the client. It comes straight from Excel with
       | letterhead and fonts virtually indistinguishable from Word. At
       | the beginning with MS-Word I was faxing with a dedicated land
       | line plugged directly into the PC, now email or not when the
       | client prints it there are very few ways to tell the difference
       | from when I would fax them a signed page from my typewriter too.
       | 
       | It took quite a while to reach the point today where AI might be
       | getting close enough in my lifetime to where I could train it to
       | fill in that blank tab for me.
       | 
       | It would have to be about perfect though.
