Comment Phone navigation vs. Car Radio (Score 1) 27

My car radio has Bluetooth. Works really well for phone calls, and has a good microphone built into the car ceiling near the driver. Unfortunately, it doesn't get along with the navigation applications in my phone; they're not phone calls, so it doesn't play them. (Maybe it would if I set the radio for MP3 mode or something, instead of radio? But then it wouldn't be playing the radio, whereas my Garmin doesn't care about the radio and just talks, and I pick the snarky British GPS voice because it usually doesn't sound like anybody on the radio except some BBC programs.)

Comment Sacrificial Altar, vs. Butcher and BBQ? Words. (Score 1) 109

The difference between a sacrificial altar and a butcher shop / BBQ joint is the words people say when they're there, and the article says that culture didn't have writing. If the person in charge asks the customers what favors they want from the gods, it's a temple; if they ask whether you want regular or extra crispy, it's a BBQ joint, and in some cultures they're going to thank the gods for the life of the animal even if it's a BBQ joint. In a temple, it's more likely that some parts of the animal will get burned instead of eaten, and in a BBQ joint, it's more likely that there'll be spices on the meat, and maybe priests get paid a bigger share than a butcher and cook, but none of those are universal across known cultures.

Also, the article says it was a two-story building; just because it's underground millennia later doesn't mean it was underground at the time.

Comment Good luck, as carriers stop using 2G (Score 1) 27

My Garmin Nuvi GPS no longer gets traffic data, and can't use a few other 2-way features like Google Search, because the 2G wireless network it used will be going away early next year, and the carrier's no longer renewing contracts for them. So it's back to being a dumb GPS, with maps and built-in data points, but no live search.

Carriers really want to reallocate their 2G spectrum to 4G or at least 3G, because it lets them get more calls and a lot more data in the same amount of bandwidth, and because the movement of users to newer standards means that their remaining 2G bands are very underused.

Comment Re:Cold Fusion isn't like Perpetual Motion (Score 1) 986

No, constructing something impossible, like a perpetual motion machine, is impossible. Science quite often says "definitely" or "definitely not".

Constructing something highly unlikely but not provably impossible, like cold fusion, is highly unlikely, especially if you're doing stuff by accident instead of actually understanding theory, but what science says about cold fusion is "everybody assumed it wasn't possible, but somebody did it, and then we showed that what they did was bogus but interesting, so we're back to assuming it's probably not possible so you'd better do a really good job of explaining what you're doing if you want us to spend our time looking at it again."

Oh, right, I never owned a 90s car :-) My wife's 1985 car lasted until 2001, my 1987 van lasted until 2012 (with one engine replacement), and I never played with the digital busses on either my 2012 car or my wife's 2001 car (which IIRC only had the dumber version of OBD, not the current CAN bus.) I suppose I should try that some time. Both of those cars have the electronic speedometer with analog readout you refer to.

Comment Network Transparency Use Cases I use often (Score 1) 226

Many of the remote management applications I used to do with X are being replaced by HTTP interfaces, optionally with AJAX, or sometimes REST APIs, but there are still a number that aren't.

  • - Remote logins to run Unix shell - xterm really rocks for this (these days usually with X over SSH), as long as I'm using a Linux desktop, and it's a bit lame but workable from a Windows desktop (usually using Xming.)
  • - Windows Remote Desktop Protocol remote logins to Windows servers - RDP mostly works, though running any sort of video over it is painful, and audio's worse, even over Ethernets. VNC would be similar, if I were talking to a Unix machine.
  • - VMware console access to Unix or sometimes Windows VMs - the biggest problem here is that too many different applications are carving away chunks of the screen, so there's only 800x600 or maybe 1024x768 left; and I'm usually accessing the VMware server from a web browser on a Windows machine accessed by RDP through a firewall, so there's no real way to compare video speeds or get audio.

Comment Supporting Mobile Devices on X or NeWS (Score 1) 226

We definitely have to dumb down protocols to run on mobile phones with 1024x768 screens and only 1 GHz CPUs and 1GB RAM, because they can't possibly run anywhere near as fast as they did on 1152x900 screens with 10 MHz CPUs and 4 MB RAM running X10, or 640x480 screens with 25-33 MHz 386 CPUs and (I forget how much, but not enough) RAM and X11 with Motif.

And yes, there were really good reasons for running NeWS instead of X, because some changes in which work you did on which end of the wire could make a huge difference in responsiveness and speed, and using Postscript meant that what you saw was really what you'd get, and it let you deal with problems like mouse tracking latency a lot better.

Comment Re:Auto deals worried? Luxury Cars, biz models (Score 1) 158

No, besides disliking competition in general, auto dealers and car makers have two big reasons to try to block Tesla sales

  • - Tesla sells high-priced cars, competing with the other high-priced high-profit-margin cars that dealers like to sell. They wouldn't be as worried about threats to the low-profit-margin econobox sales.
  • - They also threaten the whole business model that US car dealers have, affecting who gets what cut of the car buyer's money. This may bother the manufacturers less than the dealer, but it still upsets the whole value chain, especially if those evil Tesla car buyers then resell their old cars on Craigslist or some other Internet site instead of trading it in at the dealer or at least selling it to a used car lot.

Comment Re:Too many discrete components (Score 1) 158

I'd expect most of them are sensors for the various battery and motor things, or components to connect the sensors safely to the other electronics (opto-isolators, etc. to keep potentially high random voltages and currents from frying the whole system.) Once you've turned the analog data into bits, even with small-volume production it'd be fairly easy to use an FPGA or programmable microcontrollers to do the rest, rather than building lots of custom discrete parts.

Comment 2G-wireless GPSs (re: rant.) (Score 1) 158

My Garmin Nuvi had some cool features that depended on 2G, like using Google search instead of just built-in, and also checking movies, weather, etc. It also used that to get traffic data, instead of whatever other traffic data services are available. Now the 2G wireless is going away, since the carrier won't renew the contract, so there's no more traffic data :-( But at least it's a separate GPS, so I could replace it if I wanted to. (Instead, I use the AM radio you dislike to listen to Traffic Every 10 Minutes Radio.)

When the satellite XM radio free-with-new-car subscription on my current car ran out, no problem, that just meant there was one button on the dashboard that was no longer useful; the most likely interface to become obsolete is the Bluetooth cellphone support. There'd be a lot more risk of obsolescence if I'd gotten the hopelessly-overpriced navigation/radio/etc. console only that came with the fancy trim package (which also had the bigger engine that I didn't want, and the spare tire I really did need, and pushbutton combination door lock I'd also have liked.) While I like having a remote-control door lock, which is probably already insecure, it's built in to the keys, which means I have to carry a big clunky not-waterproof key system with me instead of a probably-waterproof slightly clunky RFID key like my wife's car has or a simple key like older cars - really annoying when I'm going surfing.

Digital speedometers might be lying; analog speedometers also might be lying, especially if there's a problem with the cable, or you've put on different sized tires.

Comment Santa Ana's losing war (Score 1) 323

Mexican history considers Santa Ana to be one of their least competent generals over the years. But after he lost, the US rejected his initial peace proposals, which would not only have given the invaders the land they got, but also the states of Sonora and Chihuahua. While they were officially Mexican territory at the time, the local Native Americans had other opinions about whether they were interested in being run by the Spanish or Mexican colonialists, and groups like the Apaches and Comanches wouldn't have been much more cooperative to the US than they were to the Mexicans.
