Same here. Our 2100TN is still running like new. I don't know that I'd be able to find a newer model as reliable.

I've had pretty good luck the past 10 or so years with a LaserJet 1320. Quick, built-in duplexer, built-in PostScript, works with everything. A couple years ago, I was given a JetDirect 175x, so it's now on the LAN. (Had some other network-to-USB adapters before the JetDirect that didn't always work as expected.)

The brand logos have been removed.

In one shot, it looks like they didn't obscure the Apple logo on the printer (upper right corner of the front), though it's so small that you wouldn't have been able to tell that's what it was.

I still have mine from coming up on 32 years ago. It's currently in storage...not sure if it still works, though it did the last time I had it out. It'd almost certainly need a new ribbon, and I think the last of the fanfold paper got chucked a while back. I still have some Apple IIs (and also some Macs now) that can drive it, too. :)

Remote workers are the people you throw under the stacked ranking bus when it's time to get rid of the people you have no emotional attachment to, so that your friends get to keep their jobs.

There's a reason Yahoo got rid of remote workers, and why they tend not to last long at companies which do stacked ranking in employee evaluations.

With the greatest possible respect because I'm sure that you are very good at something, have you considered that those items you listed are not of an appropriate size to drive tiny little robot parts and that it would be difficult to control dozens of them at once?

You realize that you can drive pretty much everything with two hydraulic lines (one a return line), some check valves, and a mechanical stepper, right?

Did you never take a "Furby" apart?

I think where you are going wrong is with the idea of "at once".

I have an idea!

Why don't we put all the water back into the aquifers we've been taking it out of, instead of letting it out, and down to the pacific?

What a lamentable situation! If only someone could invent something to do that!

Oh. Wait. They did. In 1992.

1992, though, was 25 years ago.

What a lamentable situation! If only a millennial could reinvent old technology in ignorance, thinking it was new, to do that!

Here are some possibly related valves produced by Bosch; I looked at one of the datasheets and it has a 15ms time to move the shuttle from full on to full off, or vice versa.


The truth is that hydraulic controls are entirely capable of performing these functions. That is not at all the limiting factor. It's more about cable management.

Completely agree. And you only have to manage it from the point at which the electronics in a standard robot would start to degrade; standard robot up to that line, hydraulic past that line.

However, this begs the question, do we actually "need something like" "the equivalent of dozens of very tiny stepper motors controlled by hydraulics"? The more I think about this, the more I think that what is wanted is a tentacle, rather than a walking or driving robot.

There's really no reason except good taste not to use a tentacle.

It's Japan... they'd pay 5x-10x premium, if it was a tentacle... ;^)

Fiber optics goes black very quickly in high radiation.

Organic plastic, yes; glass light-pipe (old-school, like that used in 1976 Buick Station Wagon instrument lighting): not a problem.

Getting the extremely radioactive and hot fuel onto a train would be rather tricky.

Pneumatic/hydraulic remote manipulators: no electronics to fry, and it's outside, so telescopic cameras would be good enough. Plus if they go into large tanks of water on the train, it's not going to boil off in time for it to matter, and a couple meters of water will stop all the hard radiation.

Burying in cement is not a bad idea, but they probably need to make sure that the radioactivity isn't generating so much heat that it would melt its way out of an enclosure.

They could talk to the Russians; they've dealt with it before, successfully, with a hotter meltdown.

Comment That's pretty stupid. (Score 1) 307

That's pretty stupid.

The third most obvious thing to do would be to send in a robot with a tether, and include a fiber optic cable, and have the camera outside with the pneumatic drivers for the pneumatic servos and other equipment actually on the robot, making the robot entirely free of all electronics, other than lights.

The second most obvious thing to do would be to load all the spent fuel that's contributing to the ongoing radiation leakage onto the end of a long train, and distribute them around to all the other nuclear power plants in Japan that still have functioning cooling ponds, and stop the leakage -- 10 days, tops, to solve the leakage problem.

The first most obvious thing to do would be to bury the site in cement and call it a day.

The U.S. Navy has offered to do that for them a half dozen times already, but given that the top two executives at TEPCO at the time now work for a Japanese oil company, there's something of a vested economic interest in keeping it an ongoing danger. "No, no: we don't need your help".

Compared to what? I personally find it much more convenient that my non-Apple mobile phone works absolutely everywhere which has an NFC reader without a specific negotiation between a bank or merchant benefiting only Apple.

I find it convenient that your NFC phone works that way, too.

I'm the person sitting in the car across the parking lot, staging a pre-play attack against your NFC device while you are doing your transaction, because there's not a one time cryptographic nonce, like in the Apple Pay system, which would prevent the attack.

That's me waving at you now.

Yes, your latest purchase is going to show up twice on your statement, and the amount deducted twice. Thanks for your contribution! You can take it up with your merchant when the bill comes; your money is already in a bank halfway across the planet.

By the way: I also plan on an attack on the chip-and-pin system at the same store, if you switch back to using cards, but I'm going to have to actually sit down and case the joint a bit, before I decide which of the 9 identified (so far) ways to hack a chip-and-pin transaction.

Don't you wish you could go back to the days of the old fashioned skimmers, where instead of you eating the losses (because "the new system is so much more secure"), the banks and credit card companies had to eat them?

I _think_ T-Mobile is planning to drop 2G GSM

It's AT&T that's shutting down EDGE (aka "2G") service in the near future (it may have already happened, as the link says "by the end of 2016"). T-Mobile, OTOH, has committed to keeping its EDGE service going through at least 2020, ostensibly to support gadgets with cellular-data connections that aren't easily updated to newer standards.
