On the military balance of power in the Western Pacific

Some observations concerning the military balance of power in Asia. Even “experts” I have spoken to over the years seem to be confused about basic realities that are fundamental to strategic considerations. 1. Modern missile and targeting technology make the survivability of surface ships (especially carriers) questionable. Satellites can easily image surface ships and missiles …

Ratchets Within Rachets

For those interested in political philosophy, or Trump’s travel ban, I recommend this discussion on Scott Aaronson’s blog, which features a commenter calling himself Boldmug (see also Bannon and Moldbug in the news recently ;-) Both Scott and Boldmug seem to agree that scientific/technological progress is a positive ratchet caught within a negative ratchet of societal and …

Pro Bono Analytics Is Growing Social

Pro Bono Analytics is a program by INFORMS (the Institute for Operations Research and the Management Sciences, for the acronym-averse), “the largest society in the world for professionals in the field of operations research (O.R.), management science, and analytics”. PBA “connects our members and other analytics professionals with nonprofit organizations working in underserved and developing communities”. …

AlphaGo (BetaGo?) Returns

Rumors over the summer suggested that AlphaGo had some serious problems that needed to be fixed — i.e., whole lines of play that it pursued poorly, despite its thrashing of one of the world’s top players in a highly publicized match. But tuning a neural net is trickier than tuning, for example, an expert system …

Mapping Trackball Buttons

For years, I’ve used a Logitech M570 wireless trackball with my Linux Mint PC. I generally prefer trackballs to mice — no need to lift and reposition after a bunch of movement — and I find that using my thumb, rather than my index finger (or, if I’m in a bad mood, my middle finger) …

Mint Upgrade Woes

As I mentioned a couple of months ago, I upgraded a laptop from Linux Mint 17.3 (“Rebecca”) to 18.0 (“Sarah”) with minimal difficulties. My laptop serves as a guinea pig for these things. Once I’m sure things work fine on the laptop, I’ll consider upgrading my desktop as well. A few days ago I finally …

Toward A Geometry of Thought

Apologies for the blogging hiatus — I’m in California now for the holidays :-) In case you are looking for something interesting to read, I can share what I have been thinking about lately. In Thought vectors and the dimensionality of the space of concepts (a post from last week) I discussed the dimensionality of the space of …

Shift Commission on Work, Workers, and Technology (New America Foundation and Bloomberg)

I spent yesterday at this event. If you look carefully you can see Tim O’Reilly in one of the photos below. New America and Bloomberg are convening the Shift Commission on Work, Workers, and Technology to bring together a community of leaders from different disciplines — technology, business, policy, civil society, academia, and others — who want to understand …

Perdurance

I had a great idea for this week’s blog sometime around Wednesday of last week, but then I forgot what it was. I don’t think that this is a sign of senility in my particular case, but it does suggest that I’m wearing out my willingness to dedicate some of my brain cells to cogitating …

Surviving an nVidia Driver Update

Scenario: I’m running Linux Mint 17.3 Rebecca (based on Ubuntu 14.04) on a PC with a GeForce 6150SE nForce 430 graphics card. My desktop environment is Cinnamon. The graphics card is a bit long in the tooth, but it’s been running fine with the supported nVidia proprietary driver for quite some time. Unfortunately, having no …

Low Earth Orbit from your backyard? (startup Vector Space Systems)

It’s great to see innovation and competition in space launch technology. These small launchers from startup Vector Space Systems can put 50-100kg payloads (e.g., micro satellites) into Low Earth Orbit (LEO) for $2-3 million. There are obvious military applications for the rapid placement (or replacement) of satellites. For example, see A2AD Fait Accompli? Commercial applications are …

Mint Upgrade Problem Solved

I decided to upgrade first my laptop (the canary in the mine shaft), then my desktop (assuming the canary lived), from Linux Mint 17.3 (“Rebecca”) to 18.0 (“Sarah”). The “old school” approach would be to download the distribution to a CD/DVD, or create a bootable version on a USB stick, test it and then install …

AI, Westworld, and Electric Sheep

AI, Westworld, and Electric Sheep I’m holding off on this in favor of a big binge watch. Certain AI-related themes have been treated again and again in movies ranging from Blade Runner to the recent Ex Machina (see also this episode of Black Mirror, with Jon Hamm). These artistic explorations help ordinary people think through …

DNS on Home WiFi

DNS on Home WiFi Like a lot of people, I have a home WiFi network, and I recently changed my Internet service provider. That required replacing my cable modem. Both the old and new modems provided a DHCP service that doled out local IP addresses to devices connecting to the home WiFi network. Both modems …

Becoming a Digital Scholar

Recently, I’ve posted a couple of times on my efforts to make connections with the world of digital humanities. This week, I continue those efforts by attending for the first time a Digital Humanities methods seminar that I’ve enrolled in. As I’ve mentioned in those previous posts, I’m still working to figure out if/how I—an …

Hovering Over Shiny Plots

I’m following up on yesterday’s post, “Formatting in a Shiny App“. One of the features I added to my Shiny application was the ability to identify a point in a plot by hovering over it. Since I wanted to do this in several different plots, and did not want to reproduce the logic each time, …

Formatting in a Shiny App

I’ve been updating a Shiny (web-based interactive R) application, during the course of which I needed to make a couple of cosmetic fixes. Both proved to be oddly difficult. Extensive use of Google (I think I melted one of their cloud servers) eventually turned up enough clues to get both done. I’m going to record …

TPACK in Spanish

Back in 2013 we (Koehler, Mishra and Cain) published an updated version of an article on TPACK. Koehler, M. J., Mishra, P., & Cain, W. (2013). What is Technological Pedagogical Content Knowledge (TPACK)? Journal of Education (193)3, 13-20. This article was then picked up, translated into Spanish and published in the journal Virtualidad, Educación y Ciencia (Virtuality, Education …

Connecting Bluetooth Headphones

I recently picked up a pair of Bluetooth headphones (Mixcder ShareMe 7) for use with my laptop (which runs Linux Mint). Getting them to connect properly was a bit of an adventure. After I had things (mostly) sorted out, I decided to script the steps necessary to get them working so that I could just …

MathJax Whiplash

Technology is continuously evolving, and for the most part that’s good. Every now and then, though, the evolution starts to look like a random mutation … the kind that results in an apocalyptic virus, or mutants with superpowers, or something else that is much more appealing as a plot device in a movie or TV …
