FYI, if you meant to type “invest in education” but actually typed “incest in education,” which you might do because the ‘c’ and ‘v’ keys are right next to each other, a spell checker will not catch that as a mistake . . .

Teaching Computer Science

1 Sep 2014 /
School

Tomorrow is my first day as an AP Computer Science teacher at Corona del Mar High School. It’s a volunteer gig through the TEALS organization.

Only about 10 percent of U.S. high schools offer computer science classes and at most of those schools, it counts as an elective, like Home Ec or Wood Shop, not as a class that can be applied toward graduation like math or science.

The most popular AP exam in 2013 was US History — 439,552 students took the AP US History exam. Only 31,117 students took the AP Computer Science exam. That’s about the same number as the AP Art History exam. I don’t want to denigrate the study of art history, but given the ubiquity of computers and software and programming in daily life, the study of computer science seems more likely to enable a person to be self-supporting and to contribute to the common good.

I’ve heard people say that computer science should be taught in every high school in America. That may be a good idea, but no one ever says where all the qualified computer science teachers are supposed to come from. The TEALS vision is to put high-tech professionals like myself in schools to teach computer science and to teach teachers to teach computer science.

I’m happy to have the opportunity but I’m also scared, I might as well put that out there. What am I scared of? Like everything else, that I won’t perform to expectations and that I’ll be exposed as a phony.


People Who Don’t Want Me to Know Things

12 Jul 2014 /

What I want to know is why there are so many people who don’t want me to know things . . .

Trudeau's book Natural Cures Updated Edition

And that doesn’t even include all the things that people “won’t tell me.”

The Cure for Missing Attachments

10 Jan 2014 /

I wrote an email in Outlook 2013, concluded by saying “Details are in the attached doc,” then clicked Send without attaching the aforesaid document.

I must not be the only person who does this, because when I clicked Send, this dialog box appeared:

Attachment reminder

Obviously, Outlook is looking for words like “attached” or “attachment” in emails that don’t contain an actual attachment. It turns out that this behavior can be turned on or off in the Outlook Mail options:

 Mail options

I have to admit that I don’t remember if “warn me” is the default option, or if I turned it on at some point in the past and forgot about it.


It Would Be Important to Get There and There is Probably a Way

I often say, “Well, it’s just over on the other side of that canyon. So all we have to do is go.” It is always surprising to me that other people would expect me to tell them how we’re going to get there directly. That it is not enough to say, “Well, it would be important to get there and there is probably a way. Let’s go.”


Pictures of Food

“The Basket of Apples” by Paul Cézanne

Years ago, if you wanted to show your friends a picture of your food, you’d have to break out the palette and the easel and paint one. Time-consuming!

Nowadays, with the likes of Facebook and Instagram, it’s just point and click!

Another way life gets better and better thanks to computers . . .


Do You Want to Take the Human Race to the Next Plateau?

In 1986, Steve Jobs famously challenged John Sculley, asking him if he wanted to keep on making sugar water or help Apple change the world. While that did not quite work out the way either of them intended, the challenge itself still holds. Do you want to spend your next decade developing more digital distractions to amuse people while they stand in line at Starbuck’s, or do you want to take the human race to the next plateau?


From Science Fiction to Everyday Life in Just a Few Years

25 May 2012 /

This is the world we live in now. It’s one where computers improve so quickly that their capabilities pass from the realm of science fiction into the everyday world not over the course of a human lifetime, or even within the span of a professional’s career, but instead in just a few years.

Intelligence in the Cloud

12 Mar 2012 /

IBM Watson, the Jeopardy champion, runs on 90 IBM Power 750 servers, with eight 3.5 GHz cores per server.

Currently on Amazon EC2, eight extra large compute instances will cost you $2.40/hour. If you want to run 90 of them, you’re looking at a shade over $200/hour.

This brings up a couple of questions:

  1. For what tasks could artificial intelligence be as good or better as a highly trained person at $200/hour?
  2. What would this mean for society?

Thanks to David Patterson at UC Berkeley for bringing this to my attention.


Tom Knight and the Lisp Machine

8 Mar 2012 /

A novice was trying to fix a broken Lisp machine by turning the power off and on.

Knight, seeing what the student was doing, spoke sternly: “You cannot fix a machine by just power-cycling it with no understanding of what is going wrong.”

Knight turned the machine off and on.

The machine worked.


Race Against the Machine

19 Nov 2011 /

We don’t believe in the coming obsolescence of all human workers. In fact, some human skills are more valuable than ever, even in an age of incredibly powerful and capable digital technologies. But other skills have become worthless, and people who hold the wrong ones now find that they have little to offer employers. They’re losing the race against the machine, a fact reflected in today’s employment statistics. . . .

There is no economic law that says that everyone, or even most people, automatically benefit from technological progress.

Good Lesson for Mac Snobs

6 Jun 2011 /
Apple television commercial

Just hours after Apple issued a security update to protect Mac users against a rash of scareware attacks, a new variant began circulating that completely bypasses the malware-blocking measure.

It’s no harder to write malware for Macs than PCs but it’s no easier either. Given the commensurate level of effort, most malware authors elect to target the platform that most people use.

Good lesson for Mac snobs and everyone else who thinks Macs are inherently more secure than PCs.


Everything Must Be Replaced

4 Apr 2011 /

Uh oh, it looks like the wireless connection here at EppsNet headquarters just went down . . .

“NOTHING MAKES ME ANGRIER THAN AN UNRELIABLE NETWORK CONNECTION!” my son yells. “WE NEED A NEW ROUTER! WE NEED A NEW MODEM! WE NEED A NEW SERVICE PROVIDER! WE NEED NEW COMPUTERS!”

“We don’t need new computers,” his mom says.

“YES WE DO!”
