Comment Khan Academy isn't smart. (Score 0) 243

Khan Academy isn't smart. I watched one of their "courses" on moments of inertia. It's a colored etch-a-sketch of someone writing, with voiceovers. There were major factual errors and wrong signs. It's low-budget content with no proofreading or editing. Subjecting kids to that is just wrong.

If we're going to have have massive online courses, the quality needs to come up to at least History Channel level.

You don't have to put up with jerks.

  • Internet provider - Sonic.net DSL. No packet filtering, good support, no nonsense.
  • Phone - Caterpillar B15 ruggeized Android phone.. Bought from Caterpillar dealer, not carrier. Declined Google account at first power up. Google services disabled. No updates from Google.
  • Cellular carrier - T-Mobile. Has no control over phone. No carrier apps.
  • Email - IMAP server. SpamAssassin spam blocking.
  • Main desktop machine - Ubuntu 12.4 LTS.
  • No Google account. No Twitter account. No pay TV. Ad blocking on all browsers.
  • Main news source - Reuters. (More news about Ukraine and ISIS, less about Bieber and Apple.)
  • Main food store - Trader Joe's. No "club card" required. Good prices.

For almost every crap business, there's a competitor that isn't crap. Find them.

Comment No big deal (Score 2) 190

This is a straightforward industrial electrical installation. There's a pad-mounted distribution transformer and meter provided by the power company, a weatherproof load center provided by the customer's electrical contractor, and the Tesla supercharger control unit and outlet stations. No big deal to install. There's a comparable installation at every large standalone store.

That's a small charging station. Here's the build-out of a bigger one. Black and Veach, which does infrastructure construction for the energy and communications industry (substations, cell sites, etc.) is doing the job. They see it as a lot like building out cell towers. (If you watch that video, you may wonder why the transformers and switchgear are on raised platforms. Probably because there's a flood risk at that location.)

Installing a gas station's underground tanks, which today are dual tanks with leak detection, is a much bigger job. There's a big excavation, lots of plumbing and wiring, and several different trades involved.

Comment Re:There is no "FarmBot" (Score 1) 133

If you watch the video at the bottom of the article, you'll see photos of several prototype FarmBots that do, in fact, exist.

Those are just tabletop gardening robots. That was done 20 years ago.

There's lots of real robotic agricultural machinery, much of it mobile. Building a gantry over a tabletop doesn't scale.

Comment Re:The power of the future... (Score 1) 305

Fusion power is roughly 20 years away from being viable...and has been for the last 40 years LOL.

Longer than that. Fusion power has been hyped since the 1950s. From the article:

Nuclear fusion could come into play as soon as 2050

Heard that one before.

Fusion power has some real problems. After half a century of trying, nobody has a long-running sustained fusion reactor, even an experimental one. The whole "inertial fusion" thing turned out to be a cover for bomb research. There's a lot of skepticism about whether ITER will do anything useful. It's not clear that a fusion reactor will be cost-effective even with a near-zero fuel cost. (Fission reactors already have that problem.) It's really frustrating.

Fusion reactors are a pain to engineer. They have a big vacuum chamber with high-energy particles reacting inside, and huge cryogenic magnets outside. This is far more complicated than a fission reactor, and is why the cost of ITER keeps going up.

Comment LibreOffice/OpenOffice still kind of suck (Score 5, Insightful) 579

The basic office-type products for Linux still kind of suck. I've been using them since the StarOffice/SunOffice days, and now use LibreOffice. They've improved a lot, but they're still flakier than they should be, a decade after initial release. Nobody wants to fix the hard-to-fix, boring bugs which damage usability.

Oracle buying the remnants of Sun didn't help.
