The Social Security Scammer called again

This pitch starts off telling me my social security number will be trashed somehow.  And asks me to call back at another number.  They called me yesterday and again today.  I hung up both times.  US guvmint operations don't telephone, they send letters. 

Advice to the class of 2023, frosh this fall

That's you frosh entering college this fall.  College is fun and parties. I enjoyed it all immensely.  It's also serious stuff.  We are talking serious money for a 4 year bachelor's degree, like $100K, which either your parents put up, or you take out US guvmint loans for.   If you take out guvmint loans, know that you are stuck with the payments, declaring bankruptcy doesn't get you out of paying them off.  You are stuck.
   First thing you need to decide that you are gonna graduate, on time, no matter what.  If you give up and flunk out before getting your degree, all the money spent is wasted, you don't get squat for it, but you still have to pay off your student loans.
   Second thing you need to decide is what you want to do to make a living after you graduate.  You have to make a living somehow.  You will spend much of the rest of your life after college making a living. Best to find something that you like to do.  Selling used cars or waiting tables can get old, fast.  At this stage of your life you may not have a clue.  Talk to your parents, talk to your family, talk to friends, do some reading of biographies.  You need to have something in mind by Christmas freshman year.  Given you have chosen a career field, pick a college major that makes you employable in your chosen field.  Colleges and universities offer many majors that are totally worthless in the job market.  Avoid any major with "studies" in the name.  Gender studies, black studies, environmental studies. Avoid art history, sociology, archeology, and political science. Nobody hires graduates in those majors.
   Think about STEM majors.  Those are valued in the job market.  For you kids entering high school, be aware that STEM majors require integral calculus.  The subject matter is taught using calculus and if you don't have your calculus, the courses won't meant anything to you.  Figure you have to take integral calculus freshman year.  To do which, you have to have taken trigonometry and algebra in high school.  A high school course in geometry is extremely helpful, although not mandatory.  Plan your high school courses accordingly.
  Finally, beware, colleges have all sorts of obscure graduation requirements.  You have to have so many credits in a bunch of strange subjects.  If you lack ALL the required credits you don't graduate with your class.  Get a current copy (last year's copy may be obsolete) of the college catalog and research all the credits needed to graduate in your major.  At my school engineering majors needed 15% more credits to graduate than education majors.  Make a spreadsheet and print it out.  Bring it to your appointment with your college counselor.  Ask him if it is correct.  Remember that counselors have about 100 other students to counsel, and papers to grade and classes to prepare for, and don't have much time to help you.  Plus they see their mission as recruiting more students to their academic departments.  Listen to counselors but don't trust them much.

That Mueller hearing yesterday

I watched it with maybe just one eye.  The hearing  was long, very long.  Each congresscritter in two committees got 5 minutes to question Mueller or just make speeches.  The Democrats would read aloud from the 400 odd page Mueller report and get Mueller to agree with it.  This served to get points from the report before the public.  Few people have bothered to read the Mueller report.  I haven't and I don't plan to.  It is too long, written in lawyer's gobble de gook which can mean almost anything depending upon who is reading it.
   Republicans seized on inconsistencies in the report and grilled Mueller about them.  Mueller did not look good answering.  In one case he admitted ignorance of the Steele Dossier, which has been headline news for months.
   A lot of talk about "obstruction of justice".  Early in the report they state that there is no evidence of "collusion" between the Trump campaign and bad guys.  If there is no crime, how can there be obstruction of justice?  That was never explained.  

Looking for Global Warming.

NASA at the Goddard Institute of Space Studies (GISS)  has posted their temperature data base.  It goes back to the invention of the thermometer back in the later 1600's.  I downloaded the whole thing some years ago.  The records were fixed length, 80 bytes long, no separators like comma's.  Clearly showing their origin on IBM punch cards.  I last used punch cards on a Raytheon job in back 1972.
  I wrote a C program to convert the ancient data format into something modern that Excel could read.  I plotted number of records vs date.  As expected, there are few records from the late 1600's.  The number grows over the years to a million or so.  Then in the early 1980's, a great weeding out happened, and the number of records per year drops to a third of its peak in 1980.  You have to wonder which reporting stations were dropped, with no explanation.  Where I live, it is 5 degrees cooler in summer and 5 degrees warmer in winter than it is down at the bottom of three mile hill in the village.  If a Franconia Notch reporting station was axed, it would increase global warming.  If a Franconia village reporting station, only three miles away, was axed it lower global warming.  When they axed two thirds of the reporting stations I wonder which ones got the axe.  The warmer stations or the colder stations? 
  Next I plotted the reported temperature data going back to the beginning in the late 1600's.  GISS furnished two data sets, a raw data set and a "corrected" data set.  The raw data set plotted out properly, a smooth line, obviously real data.  The "corrected" data set had a problem starting around 1860.  Data before 1860 was obviously bad, it had vertical jumps, bumps and discontinuities.  Just looking at the plot I could tell that something in the "corrected" data was wrong.
  So,  working with just the raw data, I  subtracted the average temperature from each year's temperature, yielding temperature rise or fall going all the way back the the late 1600s.  Temperature rise peaked back in 1990 and has been flat ever since.
   I believe in things you can measure, far more than I do computer models.   

Trashing Donald Trump

TV has been full of unhappy talk about the president's tweets concerning "the squad", four lefty democrat congresswomen.  They have been calling the president racist (the all purpose democrat epithet) and I forget what else, but they are clearly unhappy with the president's tweets.
   With so much smoke, there ought be some fire down there somewhere.  I  logged into my Twitter account and read the last week of Trump tweets.  He came down pretty hard on the squad, but I didn't see anything racist or  out of line.  Trump was trashing his political opposition for their political ideology, which is a perfectly legitimate thing for a sitting president to do, IMHO. 
   From the loudness of the squeals I think he hit a sore spot. 

Riding High. What could bring down America's economy?

Cover story of the Economist this week.  Clever front page cartoon based on that old 1930's photo of ironworkers taking their lunch sitting on a steel girder way way up in the air.  They only mention Democrats, the most severe threat to the American economy, once in the very last paragraph of the article. 

Anyone know how to clean up Win 10 Explorer???

Used to be, back with Win XP, explorer would display one and only one icon for each file and folder on the drive.  Which is the way it ought to be. 
Win 10, thru a bug or a ding-a-ling design choice, shows multiple icons for the same file.  Some of this is "libraries", an unexplained concept, for which I never found a use (or an explanation).  I turned off the " library" icons in explorer.  Click on View, click on "Navigation Pane".  Click on the arrow of Navigation pane to expand the sub menu, and uncheck libraries.  That cleans up a decent amount of clutter. 
   Some of the clutter is a bunch of busted shortcuts invented by Win 10.  When clicked upon they yield error messages rather than taking you any where useful. I delete them when I find them.
   There are still too darn many cases of multiple icons which point to the same file.  I don't dare delete the icon, fearing that it might delete the file instead.  Dunno what to do about trimming back  that clutter. 
   I would welcome any advice.
