We're missing a few parts to actually do the math, here... like the forward voltage of the diode, the maximum continuous current rating, the power dissipation rating of the diode...
There's a lot of 5mm super bright LED's to choose from, and they don't all behave the same.
And yes, a lot of diodes will light acceptably at half of maximum current.
in the real world most LEDs will run so hot with that much current they will burn your fingers and/or burn out the LED.
My math says that's.028 watts dissipated by the LED. 20mA is not unreasonable for most LEDs I recognize. (In fairness, I use the big through-hole LEDs, since that's what I have a supply of on the bench, and they're usually 2.1v, not 1.4v.)
20mA @ 5V is.1 watts TOTAL, between the.028 watts to the LED and the.072 watts burned by the resistor. This doesn't seem like enough to burn most through hole components, and even commonly sized (0603) surface mount resistors should be able to handle this easily.
If it's any consolation, as one of the 3-4 hour offline people, I find that I need to do catch-up sleep every 10-12 weeks - I'll end up sleeping through most of a weekend.
While this is purely subjective, yes, my ability to concentrate is altered in general (most days, following a "short sleep") as compared right after a weekend of sleeping.
As practical consideration, most of the world understands your sleep cycle. Most of the world does not understand my sleep cycle, and does not like to accommodate the fact that I'll elect to not get up and go to work if I'm able to get an extra 6 hours of natural sleep on a particular morning. (I've got my boss trained, fortunately.)
Here at Pharmacom, we had a decision to make - we could either treat the disease, or cure it. We could have made a lot more money treating the disease, but we decided to make the world a better place instead.
And then, only release treatments for the other 4600 diseases they have cures for, so they can seem like they really are a good company*.
My understanding was that the vehicles were not inherently illegal, but that they would not pass the EPA emissions standards on the commonly available diesel fuels from 6+ years ago. Now that the US is largely switched over to ultra-low-sulfur diesel, it shouldn't be a problem.
I'm pretty sure they don't care what they're selling, so long as they're making money.
If people want to buy biofuel instead of petrofuel, and they (the company) can produce (and distribute, etc... the whole chain) it for less than the price people want to pay, there's money to be made.
I've yet to hear anyone in business say "I don't want to make money."
If biodiesel was 30% less expensive than gasoline, I would expect to see a market shift within 5 years.
The technology is available now, but diesel cars don't seem to be popular in the US - probably because diesel is 20% more expensive than gasoline in the US. In Europe, where gasoline and diesel fuel prices are much closer to even, diesel cars are far more common.
That's right, I think fully automatic rifles, grenades, RPGs, Javelin missiles, and shoulder fired AA missiles should be available at every Walmart.
Probably not going to be in stock at every Walmart. It may have to be ordered from the warehouse, and there's likely to be a 14 day waiting period while they do the background check, anyway.
should your brother have a Federal Case against him he guesses your password and installs a jokey screensaver? because thats what the law currently reads.
That's not my reading of 18 USC 1030.
(a)1 - prohibits computer access to/interference with classified information
(a)2 - prohibits access to (A)financial records of financial institutions, (B)government files, (C)information from protected computers
(a)3 - prohibits access to restricted access government computers
(a)4 - prohibits fraud through accessing protected computers (just using the computer is explicitly exempted, so long as it's less than $5000 of use)
(a)5 - prohibits causing damage to protected computer system
(a)6 - prohibits disseminating passwords (and equivalent) for protected/government computers
(a)7 - prohibits extortion of the "pay me, or i'll hack your computer" variety
Installing a jokey screensaver probably doesn't constitute causing damage under 18 USC 1030(a)5, and unless he's really pissed me off (not lately, he's a pretty good kid), it probably doesn't constitute unauthorized access, either.
A more relevant question - if your computer gets hacked or malwared, and someone starts selling your bank account passwords that they learned through that attack, do you want that to not be a federal crime?
Yes, RAID-5 or 6 would be much better - distributed parity - even when one of the providers is down, only some of the pieces will require recovery
I see absolutely no advantage to that (RAID5 or RAID6 across several providers). Mirroring provides redundancy; if it's an unacceptable risk level ("ohnoes! what if both providers go out of business in the same week?"), that's when you add more into the mix. (Of course, if that's an unacceptable risk level, you should be doing it in-house instead of outsourcing. There's a good chance if your own organization ceases operations and can't provide you the storage service, your internal customer will have simultaneously stopped needing the service - win-win!)
Mirroring doesn't require "recovery" like a rebuild from partial data + parity. It just works.
Yes, this has wandered far from OP's original question. How would I do it?
1. I wouldn't, if possible
2. iSCSI, if possible (not really, if you want to use "free cloud storage" as a backend)
3. Find something that can mount the storage (SSHFS, or some other FUSE method), and copy the already encrypted files to/from it, repeat as needed for more copies on other providers, if I had to
Can't the McDonalds operators call the police on you if you sit there for hours?
My understanding is they generally choose not to, unless they're quite busy, or you're a nuisance.
I expect it does better things for their public image to let people quietly study there than any amount of broadcast advertising about $1 beverages.
I don't think the glass fiber much cares what's running over it. Just replace the gear on each side of the run as a set.
Good luck getting a glass of wine with your medium rare steak.
There is a difference between feeding pigeons and serving pigeon.
Unless it's a sealed homogeneous environment, yes. Pretty sure they've got some ventilation, which means moving air.

That'd be EST, and isn't the general consensus that most /. users are in North America?
It's only interesting because you can't remember having read an article like this before.

a beefburger rarely contains 100% beef.
... and a hamburger rarely contains 100% ham.
I wish I was very young and everything was new and exciting. That is how truly new things get done/invented/developed.
Sometimes things get done when the old codgers get sick of the whippersnappers fouling things up, and the codgers take over and show 'em how to do it.
... but that's a young man's game.
why would big pharmacy want to produce this?
PR.

Most of the traditional "diesel smell" is from older diesel fuels.
The combustion products of low sulfur, ultra-low-sulfur, and biodiesel smell very different.
My understanding was that the vehicles were not inherently illegal, but that they would not pass the EPA emissions standards on the commonly available diesel fuels from 6+ years ago. Now that the US is largely switched over to ultra-low-sulfur diesel, it shouldn't be a problem.

That being said, I would feel pretty betrayed to find out that the American company I hired was simply outsourcing my request to a foreign entity.
Then be sure to stipulate that in the contract you negotiate.
The IRS will have MUCH to say over this. Of that you can be sure.
I'm curious - why?
The individual hired a Chinese consulting firm to produce code. The subcontracted agency seems like it would be outside the authority of the IRS.
Someone should oughta edit the summary and append that URL.
Someone else (Verizon) should make their webserver a little more robust.
I had no idea websites still got slashdotted.
