Comment Re:I wish they would... (Score 1) 56

I try to focus about 80% of the grade on higher orders of thinking than recall (see Bloom's Taxonomy for what this means).

Bloom's taxonomy is a wonderful paradox. It takes the idea of higher order thinking and presents it in an easy-to-digest form that requires no higher-order thinking whatsoever. Higher order thinking skills exist outwith and beyond the taxonomy, and any explanations I've seen tied to the taxonomy are weaker than those independent of it.

So please, can we kill Bloom's Taxonomy now? It has outlived it's usefulness by a long chalk.

Comment Re:Getting a job (Score 1) 56

One of the problems in modern education is the blurring of the lines between "academic" and "vocational" education. In vocational courses, work release, sandwich courses etc were the norm, but more and more, people are being pushed into universities rather than technical colleges/trade schools. Really, the university sector is too large, and we should be attempting to rejuvenate the vocational education sector instead.

That said, I am always very dubious of "skills useful for a job", because the more you talk to industry figures, the narrower that gets. In CS, for example, you end up with students spending a long time working with a specific package and getting good at using it, but never having the time to learn more abstract principles. Someone coming out of a rigorous traditional university education will need training for their first job, yes. However, they'll be able to pick it up quicker, and they'll find it easier to retrain for their next job/role much easier because of the breadth of their backgrounds.

Consider functional programming. How often have you heard industry figures decry CS faculties for teaching it when it was not a "real world" technology? My second year CS programming was in ML after first year being in C, and the next year the course was updated to use Java in both first and second year. And now as parallel and distributed programming takes off, people are scrambling to skill up on FP to get their servers running efficiently. (Yes, it's languages like Haskell rather than ML, but the basic principle of FP carries over.)

Why should the instructor provide the "right" answer? You are given unlimited attempts at the weekly quizzes and any course projects.

A mistake is something to be learned from -- having access to a worked answer allows you to diagnose your own errors. This is important enough in face-to-face teaching, but in the Coursera model there is no personal tutelage, and no scope for individual or common student errors to be addressed in later sessions of the course (because the content is fixed). This makes it absolutely vital that students can spot and work on their own weaknesses.

Comment Re:Why use untrusted wi-fi? (Score 1) 47

For 120$ a month, I get four lines with unlimited text, voice, and 2GB of "high speed" data. Then it gets throttled to 128 kbps. That speed is good enough to provide turn-by-turn driving instructions. I don't stream videos. So I don't even use this much of data. Anyway if I am a security professional, the company issued phone would come with some decent wireless data plan provided by the employer.

Comment Operation Quicksilver needed. (Score 1) 332

Operation Quicksilver was a WW-2 operation by Allied Army stationed in UK. They created a fake army with inflatable tanks, and cardboard barracks and painted log canons. But the deception unit also sent thousands of fake radio traffic, drove a few trucks endlessly around to create fresh tracks every night etc etc.

We should kickstart some crowd funding to create a mod for android that recognizes a Quicksilver password. Once the quicksilver password is entered, the phone would unlock, but log in you with a pre selected account or mode. Everything there would be very innocuous, but enough stuff to make it appear normal. We might get some crowd sourced "safe browsing history" updated daily and very innocuous email traffic and very bland but seemingly very normal WhatsApp and SMS traffic with very recent date stamps. Some AI generated Mad-Libs like combinatorial content generator.

There should be a very special Slowsilver password that would turn off Quicksilver return the phone to normal mode.

Comment Re:A Chinese diversion from climate change concern (Score 1) 131

Basically just an ACK, but it I doubt that the Chinese dictators have a decade to wait for economic self-sufficiency, and that is part of why they may be feeling forced to seize the current opportunity. They may know that their economy is about to crash in any case, and they NEED a scapegoat like #PresidentTweety. I certainly hope a bigger international fool doesn't come along later...

Minor supporting evidence in the recent assassination of Kim Jong-un's older brother. From the insane North Korean perspective, he was a dangerous pretender to the throne, but that is not a new thing. So why did they decide to kill him now? Perhaps because the North Korean government is on the verge of collapse? That would create the mess without giving the Chinese any benefit from it. Or perhaps because the North Korean's feared a Chinese invasion to install a puppet? The older brother could have been a good one, though I still doubt the Chinese want more involvement with North Korea no matter who is in charge there...

I still think my scenario is plausible, and the warm weather is coming soon...

Comment Why use untrusted wi-fi? (Score 4, Informative) 47

The data plans have become very affordable. I don't find the need to ever use "free" wi-fi. I use wi-fi at home, and then it is the standard data plan from t-mobile. I don't even use the free wi-fi provided by my employer at work. ( No, no, I am not Visvesvaraya, the legendary minister of Maharajah of Mysore who kept two sets of candles and made sure he did not use the government issued candles while attending to personal work. Just simply privacy concerns, why even let the employer know my browsing habits? )
