Comment Re:To what purpose? (Score 1) 107

I'm kind of struggling for what this is good for besides giving switch vendors a reason to push needless IDF upgrades and technology vendors yet another upcharge option.

It's actually cost-saving since you can use the same cabling.

1 gig Ethernet is already overkill for just about every desktop purpose

Yes, but that's not what it's for. It's for feeding these fancy new wireless access points, without having to do wiring. Customers will already have to purchase APs, they're not going to balk at buying a switch to feed them. It's not really interesting to the home user unless they've got multiple users doing remote storage, or if it turns out to be close to the price of 1GbE... or at least, notably cheaper than 10GbE. Then most of the few niche home users who need more than 1GbE will probably use it.

I expect it will be the RARE company that will actually need 5Gbps per workstation. Most can probably get by on 100Mbps.

The faster the network is, the more you use it. That leads to more files stored on the network and actually getting backed up. Yeah, you can back up files from workstations, but how inconvenient... and often, how fragile.

You don't have to go that far into the past. You can get a HPLJ2300. $3 or so on eBay gets you a stick-on PCB which will bypass the toner DRM. Just transfer it to your next toner cart with some nice thin double-sided foam tape. It's a drastically better printer than a HPLJ4.

However, neither of these printers will print color, which is probably a requirement for his mom. She should just go to Kinko's.

Comment Re:Just don't buy HP (Score 1) 156

I'm coming at you from an HP laptop I bought this year and have been happy with. But I bought a printer this year and after hearing that they are acting like such bastards about it I am very glad I didn't buy HP.

I am still using a HPLJ2300DN with a jetdirect card in, and I love it. But I had an HP laptop with the G71 Quadro FX1500 which had a known wire bonding problem. It took over 24 hours of phone time to get the machine replaced. Fuck HP sideways. I won't buy anything new of theirs. I hear there's another printer made about the same time as the 2300 which is a little bigger and fancier and also good, but this fucker is multi-protocol and prints 17 PPM at 600 dpi which is really enough for anyone... who's just printing documentation.

No, there are no such studies. There are studies confirming that a drop in oxygen levels to the brain, often concurrent with someone about to die, will lead to some pretty wild hallucinations, but what you wrote is just pure bullshit. There is nothing to indicate in any research that the mind is anything more than the sum of actions of several different parts of the brain.

Yeah, landing the booster right next to the refueling tanker seems little,eh... optimistic

The video is clearly stylized and not meant to be taken that literally. Unless you think the arrival of the spacecraft is supposed to make Mars spin until it develops oceans ;)

That said, while there's much to like, there's one aspect of it that's really clawing at me... the fact that they plan to make it out of composites. Including the LOX tank. We've never succeeded (and failed multiple times) at making flight-intent LOX tanks for orbital rockets. And they want to make the first time be on what's by far the largest rocket ever built? Without a lining?

Is it worth mentioning that they just had an explosion somehow related to the only major carbon fiber component in the Falcon 9 in a LOX tank?

CF becomes brittle in LOX. It leaks. And most concerningly, it's impact / shock sensitive in LOX. At atmospheric pressure it usually won't do a self-sustained burn on impact, but it chars on impact, and even that alone would be bad. But they plan to have significant pressure as well. He mentions briefly that they expect this to be one of the biggest challenges, getting stable coatings and the like. I think that's an understatement.

I just don't want to see the largest rocket ever built turn into the largest flying fireball on Earth. I don't trust composites with LOX. Composite cryogenics tanks are an active research topic, and they're making progress, but it's not a solved problem.

I've never been canoeing before, but I imagine there must be just a few simple heuristics you have to remember... Yes, don't fall out, and don't hit rocks.
