https://t.co/HSdNfODnIP — Paul Epps (@paulepps) March 10, 2024 I took a digital SAT recently. I’ve got a BA in Journalism and an MS in Computer Science, so I’m very well-rounded, like a sphere. I eat standardized tests for breakfast. The English portion, or Reading or whatever they call it now, seems much easier to me. I got 800 (out of 800) on that. There’s no more “read a column and a half of text, then answer 10 questions about it.” You read a paragraph, answer one question and move on. There are no more analogies. There are no obscure vocabulary words. Math is still math, although as noted in the story, if you’re getting a lot of answers right, then they start serving you harder questions. I got 780 on the Math portion. TL;DR: It’s an easy test. I got an almost perfect score and believe me, kids, I’ve been… Read more →

Donald Knuth: Observations About Programming and Specifications
When you’re doing programming, you have to explain something to a computer, which is dumb. When you’re writing a document for a human being to understand, the human being will look at it and nod his head and say, “Yeah, this makes sense.” But there are all kinds of ambiguities and vagueness that you don’t realize until you try to put it into a computer. Then all of a sudden, almost every five minutes as you’re writing the code, a question comes up that wasn’t addressed in the specification. “What if this combination occurs?” It just didn’t occur to the person writing the design specification. When you’re faced with doing the implementation, a person who has been delegated the job of working from a design would have to say, “Well, hmm, I don’t know what the designer meant by this.” It’s so hard to do the design unless you’re faced… Read more →
If You Gotta Go, Go Now
One of my students says she was so frustrated with an assignment she was ready to throw her computer out the window. “What floor do you live on,” I ask. “Second.” “Oh, well that probably wouldn’t kill anyone, just a bump on the noggin. But you can’t say for sure if it hit them just right. Be sure you’re wearing a mask though when you do that.” She lives in New York. My son also lives in New York so I had to call to warn him to be on the lookout for falling computers. “Because I know someone who may be throwing one out a window. But only from the second floor so you’ll probably be able to see it coming and step out of the way.” If I lived in New York and it came down to being killed by COVID or by a falling computer, I’d take… Read more →
Chess Game of the Day: Two Knights Defense
Man vs. computer. I feel like I was winning most of the game, screwed up, then missed the opportunity for a forced draw. Some annotations below . . . 3. …Nf6 Two Knights Defense 8. …Qd5?! I’m not sure what is the point of this move. It threatens the g-pawn, followed by 9. …Qxg5 but is easily defended by a move that White would make anyway. 12. Ne4?! Maybe capturing the bishop is better: 12. Bxg6 hxg6 13. d3 Be7 14. Nc3 Qd4+ 15. Be3. 18. …Qf4 Threatening 19. …Qxh2#. 21. …Qh5 Again threatening 19. …Qxh2#. 30. Qd3? I wish I’d taken the c-pawn. Pretty much lost the advantage with this move. White can survive 30. …Re1+ 31. Kg2 Re2+ 32. Kf1 Rxh2 33. Rh4 Rxh4 34. gxh4 Kh7 35. Qe4. 31. a4?? This was even worse. Probably 33. Kg2 was the way to go. 33. …Qf2?? Allowing a forced… Read more →
Are You Sure?
I was closing out of Remote Desktop Connection Manager and got the popup shown here. Am I sure? To the extent that we can really be sure about anything, then yes I’m sure. Why is the No option selected as the default? Is there an assumption that I’m flying by the seat of my pants, acting randomly and without certitude? That I’m not a confident person? That I lack the courage of my convictions? Read more →
This is Where Your PDF Resume Will Take You
Received the following advice today: When applying for jobs, never send your resume in .docx format. Fonts don’t always get embedded and hiring managers cannot always open these files. Use PDF. Do we really want to work for managers who can’t open a Word doc? Imagine the world-class mentoring and career development you’re going to get from such a person. I mean, my wife can open Word docs no problem and she can’t even figure out how to turn on the TV. Thus spoke The Programmer. Read more →
Teaching Computer Science: The Phones Aren’t Helping You
I’m volunteering a couple mornings a week at a local high school, helping out with computer science classes. The way the classes are taught, via an online curriculum, provides a great temptation to kids to get off-task, which they do, usually by entertaining themselves with their phones. They get off-task in other ways too — web surfing, doing homework for other classes — but the main distractor is the phones . . . “As I mentioned before, I worked with another CS class a couple years ago. No phones allowed in the classroom. “I remember one day the assistant principal was in class observing . . . a student had a phone out, looking at it . . . he was holding it under the table so no one could see it, but this guy, the assistant principal, he did see it. “Oh man, did he hit the roof!… Read more →
Two Reasons For the Low Number of Women in Computer Jobs
I saw this chart on LinkedIn with the heading “Chart: Women in tech continue to face uphill battle” and the hashtag #STEMSexism. The first reason for the low number of women in computer jobs is that we rarely hear about women in computing except in the context of pay gaps, harassment, discrimination, “uphill battles” and #STEMSexism. It’s self-perpetuating. “Computing is a terrible profession for women in so many ways.” Followed by “Why aren’t there more women in computing?” You’ve answered your own question. If you think computing is a hostile profession (I do not, btw), why do you want more women to go into it? The second reason for the low number of women in computer jobs — sometimes the simplest explanations are the best — is that women prefer to do other things. Men and women are different and make different choices about their lives, as a result… Read more →
Teaching Computer Science: Asking for Help
I’m volunteering a couple mornings a week at a local high school, helping out with computer science classes. This morning, in AP Computer Science Principles, the teacher went through an explanation of the hexadecimal number system, then gave an in-class assignment for students to convert their cell phone number to hexadecimal. Not in two parts, 3 digits and 4 digits, but as a 7-digit number. It seemed pretty obvious from the interaction and the body language and the looks on their faces that a lot of students didn’t get it, but in a class of 25 students, only one student asked for help. Until the teacher finished with that student and asked “Does anyone else need help?” and eight more students immediately raised their hand. I asked the teacher, “Can I address the class for a minute?” “First off, doing a 7-digit hex conversion is not easy. I know… Read more →
Is A.I. a Threat to Humankind?
Not with a bang but a whimper, as T.S. Eliot used to say. In some countries, the people are kept in a state of submission by violence and/or threats of violence, but here in America, the same effect is achieved via mindless entertainments and gadgetry. Read more →
More Words and Phrases I’m Sick Unto Death Of
Although I can’t claim never to have said these things myself, if I had a dollar for every time I’ve heard someone say either a) “It was working fine 10 minutes ago,” or b) “It works okay on my machine,” I would be comfortably retired by now. Thus spoke The Programmer. Read more →
What Does a Programmer Do?
I was asked to give a talk last week to a high school computer science class on “What Does a Programmer Do?” (I’m indebted to Jim McCarthy for the “lords and ladies of logic” section.) Programming is problem solving. At the highest level, the problem that programmers solve is that people want to be able to do things with computers that they can’t do. And by computers, I don’t mean just the kind of computers you have on the desks here, I mean phones, watches, cars . . . more and more different kinds of devices are running software. So one good thing about being a programmer is that pretty much every field of endeavor now uses software and data. You can work at a tech company like Microsoft or Google or Twitter or Facebook, but you can also work in healthcare, finance, education, sports . . . you… Read more →

Teaching Computer Science
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… Read more →

The Cure for Missing Attachments
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: 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: 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.
