Comment: Sacrificial Altar, vs. Butcher and BBQ? Words. (Score 1) 84

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.

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.

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.

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.

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) 157

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) 157

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) 157

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.

You seem to have nailed on the head, pretty much all the "big problems" in OS X. Where I work, there was a huge migration from PC's to OS X, probably starting around 2003-2004-ish. The hardware (macbook pro) is actually among the best in the industry. Especially right now (omitting the 2011 models that had the NVidia defect, and Apple's appallingly bad handling of that). (Yeah - apple is really bad at acknowledging hardware defects, for a company that charges exceedingly "premium" price-points). Many of our developers switched, and they all pretty much have the same complaints.

The biggest gripe for me is the window (and tab) switching. Holy crap, it's terrible - compared to any other OS out there. Another big one is that there's no "home" or "page up" "page down" keys, and you have to use the fn-arrow key combinations.

A lot of the keybindings for terminal makes sense; but for some reason, you can't ctrl+a in minicom. That sucks, because you basically have to kill the program to exit. (and it's also useless, because you can't get into the config menu).

Anyway: If you really hate Mac OS, then you can simply install Windows 7, or Ubuntu. (Fedora also works, but I haven't figured out how to get the drivers for fan and cpu scaling to work right, so. . . heat, fans, crappy battery-life). The hardware makes an excellent platform for either Windows 7 or Ubuntu. (I don't think that there's another laptop in the world right now, on which, you can get a 6+ hr battery life, with Windows or Ubuntu).

I think the worst-case here, is someone who's a KDE nut, going to OS X. They are polar-opposites, in terms of customiseability.

The only reason I continue to use OS X, is because I'm invested in VMWare Fusion. It's a pretty nice product, and I use it a lot in my work.

When a black-mark can remain on your record forever, there's huge consequences.

I know a guy who was an engineer, FPGA specialist. Has 4 patents. Worked for 15 years, and his company imploded. I tried to get him a job where I work, but because he had a dishonorable discharge from the navy, no dice. (apparently, when he was 19, before he went to college, he failed to return from shore-leave for 24-hours, because he went on a bender, passed-out, and was basically kept incognito by a bunch of "bad people" with whom he had been drinking. Got in trouble for that, and it resulted in the dishonorable.) Bad judgement, for sure, but it was a small mistake. He went on to college, and go in at his first job through a professor. But now he's been unemployed basically since 2004.

If you consider the concept floated (briefly) in the movie: Aliens, the company simply dropped a large atmospheric processing installation on the planet (LV 426, at that time) and began the terraforming process. That's not substantially different than "sending autonomous robots to various locations in space to create infrastructure using local resources with advanced manufacturing technology, such as 3D printing"
