"There is a cult of ignorance in the United States, and there has always been.

to win the respect of intelligent people and the affection of children;
to earn the appreciation of honest critics and endure the betrayal of false friends;

to know even one life has breathed easier because you have lived.
This is to have succeeded."

"We will work to be an example of how we, as brothers and sisters on this earth, should treat each other.
Now, more than ever, the illusions of division threaten our very existence. We all know the truth:
more connects us than separates us. But in times of crisis the wise build bridges, while the foolish build barriers.
We must find a way to look after one another, as if we were one single tribe."

I haven't made an entry here in almost a year, but the Jan. 6 Insurrection
hearing compels comment.
"Once all the committee members had made their statements, then it was time for the
police officers to have their say. They said dozens of things that got a lot of play
on social media, news broadcasts, websites, etc. Here are some of the most notable:
"To my perpetual confusion, I saw the thin blue line flag,
a symbol of support for law enforcement, more than once being carried by the
terrorists as they ignored our commands and continued to assault us."
"There was nobody else. It was not Antifa, or Black Lives Matter, or the FBI.
It was [Donald Trump's] supporters that he sent over to the Capitol that day ...
He talks about sacrificing ... and the only thing he sacrificed was the institutions
of the country, and the country itself, only for his ego ... The rioters called me traitor,
a disgrace, and shouted that I, an Army veteran and a police officer, should be executed."
"Then the crowd, perhaps around 20 people, joined in, screaming 'Boo! Fucking n*****!' ...
And as Black officers, I believe we fought a different battle also, and the fact that we had
our race attacked and just because of the way we look, you know, to answer your question,
frankly, I guess it is America. It shouldn't be, but I guess that's the way things are."
"My law enforcement career prepared me to cope with some of the aspects of this experience.
Nothing has prepared me to address those elected members of our government who continue
to deny the events of that day, and in doing so, betray their oath of office."
– electoral-vote.com, July 28, 2021
The Washington Post adds this comment from Officer Fanone:
"So many of the people I put my life at risk to defend are downplaying or outright denying what
happened. I feel like I went to hell and back to protect them and the people in this room.
But too many are now telling me that hell doesn't exist or that hell actually wasn't that bad."
– what have we become as a nation for this to be true?
"We may be turning a corner with this virus, but the corner we turned is down a dark alley of
record infections and deaths. Mr. Trump is a self-proclaimed expert on a wide variety of topics,
but when pushed on basic topics he doesn't want to discuss, he very quickly feigns ignorance.
Since Trump took over, the national debt has exploded by more than 7 TRILLION dollars.
While the last several trillion was in response to the COVID-19 economic crisis,
at least the first three trillion was on the books well before the pandemic, while Trump was
presiding over '...the best economy we've ever had in the history of our country.' (Trump's words.)
Donald Trump did not create the social-media-driven political landscape we now live in,
but he has weaponized it. He is a consummate linguistic takedown artist, ripping apart all comers
to the delight of his fanbase but at the expense of the nation. America faces many challenges
and needs a president to build this country up. This appears to be outside of Mr. Trump's skill set.
President Trump is not always 100 percent wrong, but he is 100 percent wrong for America.
– NH Union Leader editorial, October 25, 2020
The Union Leader has not endorsed a Democatic presidential candidate in over 100 years!
Reap what you sow, Donald. Time for our national nightmare to end.
The New York Times reports, in the context of the Trump tax return scandal,
on the influence peddling that has created a gold-plated new swamp.
– New York Times, October 10, 2020
Instead of "draining the swamp", Trump has created a great, strong, beautiful swamp!
Just dropped off my ballot at a local election this weekend. I voted for "ByeDon"! You should, too!!
"All Trump can see from Park Avenue is Wall Street. All he thinks about is the stock market."

Under his leadership. During his presidency.

"The Trump re-election strategy seems to be to argue that only Donald Trump
can save America from Donald Trump's America."
– Dan Rather tweet, August 27, 2020
"There's perhaps nothing more emblematic of his presidency than this wall.
It's destructive, pointless, ineffective, racist, weak, and something the damages of
which we're going to have to be dealing with for a very long time."
– John Oliver at the end of Last Week Tonight's "Border Wall II" episode, August 23, 2020
And, in the "Trump continues to just make shit up" department...

of a person convicted by a jury of lying to shield that very president."

"I speak to your shame. Is it so, that there is not a wise man among you,
not even one, who shall be able to judge between his brethren?"

I guess there is one such wise man...
A drinking game...
"I want to thank President Trump for his (outstanding) leadership and support."
– said by every Trump lackey at every briefing, always
I think it should be a drinking game! One shot each for mention;
guaranteed you won't make it to the end of the briefing without passing out!!
"I woke up today, I was crying
Lost in a lost world
'Cause so many people are dying
Lost in a lost world
Some of them are living an illusion
Bounded by the darkness of their minds
In their eyes it's nation against nation against nation
With racial pride
Sad hearts they hide
Thinking only of themselves
They shun the light
They think they're right
Living in their empty shells!
Oh, can you see their world is crashing
Crashing down around their feet
Angry people in the street
Are telling them they've had their fill
Of politics that wound and kill
Grow the seeds of evolution
Revolution never won
It's just another form of gun
To do again what they have done
With all our brothers' youngest sons!
(so many people, so many people)
Everywhere you go you see them searching
Everywhere you turn you feel the pain
Everyone is looking for the answers
Well, look again
Come on my friend
Love will find them in the end!"
– lyrics to "Lost in a Lost World" by The Moody Blues, 1972
Listening to NPR this morning, I felt like the Native American
portrayed in that iconic anti-pollution PSA from the 70's.
I am shedding tears for what my country has become.
– me, 3/4/2020
And then, not 3 weeks later, a reminder that the heart of this country still beats in my hometown:
"And we're going to get through it because we are New York, and because we've
dealt with a lot of things, and because we are smart. You have to be smart to
make it in New York. And we are resourceful, and we are showing how resourceful
we are. And because we are united, and when you are united, there is nothing
you can't do. And because we are New York tough. We are tough. You have to be
tough. This place makes you tough. But it makes you tough in a good way. We're
going to make it because I love New York, and I love New York because New York loves you.
New York loves all of you. Black and white and brown and Asian and short and
tall and gay and straight. New York loves everyone. That's why I love New
York. It always has, it always will. And at the end of the day, my friends,
even if it is a long day, and this is a long day, love wins. Always. And it
will win again through this virus. Thank you."

"The whole world rightly condemns the use of chemical weapons in Syria,

"The problem with free speech is that it's hard, and self-censorship is the
path of least resistance.
But, once you learn to keep yourself from voicing unwelcome thoughts,
you forget how to think them — how to think freely at all — and ideas perish at conception."
– George Packer on the murders of Washiqur Rahman and Avijit Roy, quoted in The New Yorker, April 13, 2015
"If you can keep your head when all about you
Are losing theirs and blaming it on you,
If you can trust yourself when all men doubt you,
But make allowance for their doubting too;
If you can wait and not be tired by waiting,
Or being lied about, don't deal in lies,
Or being hated, don't give way to hating,
And yet don't look too good, nor talk too wise:
If you can dream—and not make dreams your master;
If you can think—and not make thoughts your aim;
If you can meet with Triumph and Disaster
And treat those two impostors just the same;
If you can bear to hear the truth you've spoken
Twisted by knaves to make a trap for fools,
Or watch the things you gave your life to, broken,
And stoop and build 'em up with worn-out tools:
If you can make one heap of all your winnings
And risk it on one turn of pitch-and-toss,
And lose, and start again at your beginnings
And never breathe a word about your loss;
If you can force your heart and nerve and sinew
To serve your turn long after they are gone,
And so hold on when there is nothing in you
Except the Will which says to them: 'Hold on!'
If you can talk with crowds and keep your virtue,
Or walk with Kings—nor lose the common touch,
If neither foes nor loving friends can hurt you,
If all men count with you, but none too much;
If you can fill the unforgiving minute
With sixty seconds' worth of distance run,
Yours is the Earth and everything that's in it,
And—which is more—you'll be a Man, my son."

what is expected than to tell them."
"If you are going to hold those around you to a standard, you have to hold
yourself to a higher standard."
"It is important to take what you do seriously, but it is equally
important not to take yourself too seriously."
"Far better is it to dare mighty things, to win glorious triumphs, even though
checked by failures...

together in the same direction."

"Can't we give ourselves one more chance
Why can't we give love that one more chance
Why can't we give love, give love, give love, give love...
'Cause love's such an old fashioned word
And love dares you to care for
The people on the edge of the night
And love dares you to change our way of
Caring about ourselves
This is our last dance
This is our last dance...
This is ourselves

Me (to Herb Simon, Nobel Prize winner, as we walked toward each other on campus

"We look at people like Jack Pidgeon or the public school teacher who
stretched the envelope for 30 years as exceptions, as anachronisms, because
only the toughest can make a life of it. And that's the key. Teaching's not
a job, it's a life. It's a commitment for life to nurture life. It should not
be so much funded as held sacred. The fact that we count it as an
expense or that we have to run it like a business is a disgrace."
– David Conrad, writing on the occasion of Jack Pidgeon's retirement as Headmaster of the Kiski School,
Pittsburgh Post-Gazette, May 25, 2002
"Children succeed in classrooms where they are expected to succeed.
Schools work best when they operate with a clarity of mission: as places to
help students master complex academic material. When teachers demand rigorous
work, students often rise to the occasion, whereas tracking students at
different cognitive levels tends 'diminish learning and boost inequality'."

"Good days, bad days, but never a boring day on this job. You do what God has
called you to do. You show up, you put one foot in front of the other, and
you do your job, which is a mystery and a surprise. You have no idea...what
God is calling you to. But he needs you, so keep going. Keep
supporting each other. Be kind to each other. Love each other. Work
together. You love the job. We all do. What a blessing that is."

"The simple view is that medicine exists to fight death and disease, and that is, of course, its most basic task. Death is the enemy. But the enemy has superior forces. Eventually it wins. And, in a war that you cannot win, you don't want a general who fights to the point of total annihilation. You don't want Custer. You want Robert E. Lee, someone who knew how to fight for territory when he could and how to surrender when he couldn't, someone who understood that the damage is greatest if all you do is fight to the bitter end."

"Gun-control advocates say the answer to gun violence is fewer guns.
Gun-rights advocates say that the answer is more guns: things would have gone
better, they suggest, if the faculty at Columbine, Virginia Tech, and Chardon
High School had been armed. That is the logic of the concealed-carry movement;
that is how armed citizens have come to be patrolling the streets. That is not
how civilians live. When carrying a concealed weapon for self-defense is
understood not as a failure of civil society, to be mourned, but as an act of
citizenship, to be vaunted, there is little civilian life left."

"The trouble with so much of the conservative critique of Obama's foreign
policy is that it cares less about outcomes than about the assertion of
America's power and the affirmation of its glory. In the case of Libya, Obama
led from a place of no glory and, in the eyes of his critics, no results could
ever vindicate such a strategy. Yet a calculated modesty can augment a
nation's true influence. Obama would not be the first statesman to realize
that it can be easier to win if you don't need to trumpet your victory."

"The damage visited upon America, and upon America's standing in the world, by
the Bush Administration's reckless mis-handling of the public trust will not
easily be undone....
Pollsters like to ask voters which candidate [Bush or Kerry] they'd most like to have a beer with, and on that metric Bush always wins. We prefer to ask which candidate is better suited to the governance of our nation."

"A gangly Illinois politician whom 'the base' would today label a RINO—a
Republican in Name Only—once pointed out that you can fool some of the
people all of the time. We now know how many 'some' is: twenty-seven per
cent. That's the proportion of Americans who, according to CNN, cling to the
belief that George W. Bush has done a good job. The wonder is that this
number is still in the double digits, given the comprehensively disastrous
record. During the eight years of the second President Bush, the unemployment
rate went from 4.2 per cent to 7.2 per cent and climbing; consumer confidence
dropped to an all-time low; a budget surplus of two hundred billion dollars
became a deficit of that plus a trillion; more than a million families fell
into poverty; the ranks of those without health insurance rose by six million;
and the fruits of the nation's economic growth went almost entirely to the
rich, while family incomes in the middle and below declined. What role the
Bush Administration's downgrading of terrorism as a foreign-policy priority
played in the success of the 9/11 attacks cannot be known, but there is no
doubting its responsibility for the launching and mismanagement of the
unprovoked war in Iraq, with all its attendant suffering; for allowing the
justified war in Afghanistan to slide to the edge of defeat; and for the
vertiginous worldwide decline of America's influence, prestige, power, and

"The familiar arguments against the death penalty apply to cases like his
[Moussaoui's], some with special force. Whether or not the prospect of lethal
injection deters ordinary murder—a questionable proposition at
best—it is perverse to imagine that it can deter the sort of murder of
which faith-based ritual suicide is an integral part. And any execution,
whatever the crime it is intended to punish, degrades the society that decrees
it and demoralizes the particular government employees who are assigned to
carry it out. A criminal may deserve to die, may deserve even to die in
terror and agony; but no civil servant deserves to be made to participate in
the premeditated killing of another person, however wicked...
The trial and punishment of any international terrorist occurs in a global political context that darkens another of the stains on capital punishment: the company it keeps. In 2005, according to Amnesty International, ninety-four percent of all known executions took place in four countries. One, China, is a Communist Party dictatorship. Two others, Iran and Saudi Arabia, are Islamist autocracies. The fourth is the United States."

"What followed was a drama of redemptive, liberating settlement on one side
and catastrophic dispossession on the other—all of it taking place on a
patch of desert land too small for easy division and too imbued with
historical and holy claims for rational negotiation. For the Jews in
Palestine, Zionism was a movement of national liberation after untold
suffering; for the Arabs, Zionism was an intolerable assault by the colonial
West against sacred ground and Islam itself. Even now, more than a century
later, politicians and scholars alike quickly betray prejudices, passions, and
allegiances in the details they select when relating the saga that led to the
U.N. Partition Plan, on November 29, 1947, and the war that began just hours

Mark in a kilt! The result of "winning" an April, 1998 Lambda Sigma (sophomore honor society) "vote-to-see-a-faculty-member-in-a-kilt" fundraiser for the American Cancer Society. For the latest in commencement fashion, check out the full-color Commencement kilts!
All this kilt wearing has sparked a trend in costumed faculty. Check out Klaus Sutner in Fall, 1999!
Even President Cohon has gotten into the act in Spring, 2002 (due, in large part, to some concerted ballot-stuffing on the part of costumed-out CS faculty)!
I, too, can get in costume for a good cause, in this case, Mortar Board's Fall, 2003 charity fundraiser.
Prior to that, I taught 15-121 for three years at our campus in Doha, Qatar when I was Associate Dean for Education from July, 2012 to December, 2014.
I was the academic advisor for (virtually) all the students in the Carnegie Mellon Computer Science Undergraduate Program from the inception of the undergraduate program in 1989 until 2012 and was responsible for all student-side issues in the program.
In Spring, 2008, I was in Qatar (!) at our campus in Doha, teaching the first half of 15-123 to our class of CS sophomores. I also taught a mini-semester version of Tom Cortina's successful Principles of Computation course to the freshmen, numbered 15-103, as well as a mini-semester course in Web Apps, 15-337, to the juniors.
I have been involved in the Advanced Placement Computer Science program (I was Chief Reader from 1994 to 1999, when the transition from Pascal to C++ occurred, only to subesquently move to Java in 2004).
I am a co-author of Karel++: A Gentle Introduction to the Art of Object-Oriented Programming. Another of the co-authors, Joe Bergin, now has a Java-like version of Karel called Karel J. Robot. Check it out!
