Ted for IRPS faculty: setting up your first Ted class

This page is for my colleagues who are using Ted for the first time in Fall 2014. The main difficulty you will encounter is that it is too flexible. There are many ways to do just about every operation. But they often look different to students. One result is that students don’t know where to find material. Another result (again, speaking from my experience last year) is that you will design a Ted setup that you want to change after a few weeks, potentially adding further confusion for students. This is just for IRPS faculty although other faculty new to Blackboard are welcome to look. Everyone else should ignore it.

Kindle books and academic research = needless pain

I’ve probably purchased 300 books in the last year for research purposes, not to mention all the fiction my wife gets (and so do I, if it costs $3 or less).  For the newer ones , buying them as eBooks is generally an option. But the state of software, DRM, and copy protection for Kindle books is a mess. Kindle’s software (like iBooks) is deliberately crippled – no copying into another document, no printing, and especially no way to copy diagrams. I’m running Kindle’s software on my Mac and on an iPad, rather than using a Kindle tablet, but that barely helps.

Joe Stiglitz disses TPP treaty: it’s for corporations, not people

Joe Stiglitz critique of TPP Trans-Pacific Partnership treaty:

 Corporations on both sides of the Pacific have an interest at lowering regulatory standards—to protect the environment, to protect consumers, to protect workers, to protect health. But ordinary citizens, our society, will suffer. So you can get corporations on both sides pushing an agenda that will be increasing corporate profits at the cost of the well-being of people on both sides of the Pacific.

…Philip Morris is suing Uruguay under an investment agreement. It says, “This interferes with our basic right to sell products to kill people.” It’s like the Opium War 150 years ago, where the West went to war because China said, “We don’t want opium,” and we said, “That interferes with the basic right to trade.”

Comparing OCR program compression: PDFpen, Acrobat, and Abbyy Finereader

I have been doing a lot of OCR, as I study more than 100 old aircraft manuals to see how aviation procedures evolved. I have them all in a database, and it’s useful to search the DB for key terms like V1 and density altitude. In the end, no single OCR program did everything, and I have ended up with 3. (OCR = Optical Character Recognition = takes scanned documents and makes them searchable, copyable, etc.) Here are some notes on my experience, with the goal of saving time for others in the future.  Continue reading

State of hacking: you need a password manager.

(I wrote this primarily for friends and colleagues. I’m posting it on my blog for efficiency/discussion/amendment.) My IT manager recently sent around a warning about phishing attacks. (And I just attended a scary CSE seminar on spear-phishing — but that is another story.) Among his advice was:

You should use a strong password on all UCSD accounts and you should never use the same password on any other account you have,

That’s perennial advice that is both good and impossible. It’s good because many (most?) web sites keep making security mistakes that lead to massive breaches, exposing millions of passwords at a time. (The recent+ 100 million account breach at Target, for example.) It’s impossible because we have a decade or more of experience, research, and discussion that says using unique passwords for each login is completely impractical, and nobody actually does it.

Why Malaysia Air 370 could not have been remotely controlled

I recently visited some friends and colleagues at Wharton to discuss my work on evolution of flying. Naturally, Malaysia Air  MH370 came up. We have continued the discussion by email since I got back. Here is a note I wrote, explaining why it’s impossible to preprogram a flight plan so that the pilots could not override it, if they were conscious.

Notice the automatic circling when it reached Athens. Everyone onboard was dead.

Sid, overriding manual override  is designed to be impossible. The pilots always have override. Indeed, the first 2 items on some emergency procedures are:

1) Disengage autopilot

2) Disengage auto throttle

and there are specific buttons to make that easy to do in a hurry. (As well as by going into the Flight computer and reprogramming it, or rebooting it, etc. ) Continue reading
