Google Offers a Million Bucks For a Better Inverter

confused one Your bulding is wired with 3 phase source. (260 comments)

Based on your commend, I suspect someone wired out your building in 230V 3 phase, since it's "close enough" to get away with in place of 120V/240V split phase; and, lets them put in more efficient 3 phase pumps and air conditioning systems. Some residential buildings and residential neighborhoods are wired out in 3 phase but the private residences only uses 2 of the 3 phases, except for the A/C system. Usually that's done in 208V 3 phase; but, it's conceivable someone could have put in 230V transformers.

130V bulbs are for applications where the source is 230V 3 phase.

confused one Re:alternative energy (281 comments)

I've seen one too many scientifically illiterate alarmists who only want to protest for protest sake. "Let's go party at the Greenpeace protest"

Greenpeace: Amazon Fire Burns More Coal and Gas Than It Should

confused one alternative energy (281 comments)

If they don't like people burning coal for power, perhaps they should promote an alternative.... like nuclear.

North America is 120 / 240V split phase. 240V is common for all large loads in homes and small businesses.

Google Offers a Million Bucks For a Better Inverter

confused one Re:it's 240V in USA/Canada (260 comments)

it used to be 110/220V and 115/230V. Over time the voltage standard has changed. it's been 120/240V for decades now. Some very old equipment has labels for 110/220V and you'll see that referenced in newer documents where someone either doesn't know the standard or is old enough to remember when it really was 110/220V. 208V/230V/460V/480V are standard 3 phase voltages most people might interact with in the U.S. I've also seen 360V. I tend to not interact with the higher voltages like 4160.

Nearly 25 Years Ago, IBM Helped Save Macintosh

confused one Re:PPC macs were awful (236 comments)

Right, so this is the infamous mac os 7 era right? Powermacs? Where motorola code was emulated to work on PPC? Apple being led by non-jobs? When Macs didnt just needed a restart every 24 hours (like windows did) but would outright ruin there system install every other week? That was the most shitty Apple period ever.

The emulator was key in allowing users to use older 68k apps on the new PowerPC chips, until the software houses released versions built for the PowerPC. A lot of companies (including Apple itself) hurt the platform by delaying their PowerPC update releases. The OS did have some issues; I'm not going to sugar coat it. Apple also took a few journeys down dark alleys with poorly designed hardware during the '90s. Of course the alternative at the time was Windows 3.1, which wasn't a utopian dream either.

Ask Slashdot: Future-Proof Jobs?

confused one Future proof... (509 comments)

Not art.

If she's not college material, send her to trade school to learn a construction trade. Having a trade means she'll be employable. Some jobs are never going to go away -- there will always be construction jobs.

If she's college material I'd recommend two paths: lf she has a math or science bent, engineering. If STEM isn't her thing, as a first step send her to an accredited business school. Follow that with a good trade school. Having the business degree means she'll be able to operate at a higher level in the industry, handling the business with the background necessary to not screw it up.

Engineering and construction jobs will never go away. You have to keep up with new technologies, techniques and trends but you'll be able to find a job.

Ask Slashdot: Future-Proof Jobs?

confused one Re:Over 190 comments in this thread so far (509 comments)

Teaching is a worthwhile pursuit but there are too many of us that know that teachers are poorly paid and constantly under attack. I can't, in good conscience, recommend that career to anyone who hasn't already expressed a strong interest.

We don't need to print small one room huts in the U.S. We have more than enough old shipping containers lying around to fulfill this requirement.

confused one Re:Is it safe? (118 comments)

Based on the number of concrete buildings that collapse in China due to earthquakes, I suspect it's not as durable as you think.

The lightbulb I've most recently acquired ...

confused one $20 (196 comments)

Replaced the 3-way bulb in a lamp with a Cree LED 3-way bulb. They think very highly of their product... and price it accordingly. If it doesn't exhibit any issues I'll start converting all the CFLs I bought 5 or 6 years ago to LEDs as they need to be replaced.

Astronomers Discover Earth-Sized Diamond

How do you plan to handle delivery? An Earth sized chunk of carbon might require delicate handling as it is drop shipped on your home. BTW, a signature will be required.

Workaholism In America Is Hurting the Economy

confused one Re:job security (710 comments)

I didn't miss the point. That was sarcasm. And, for what it's worth, the employer didn't see it that way -- they insisted I work to a project completion schedule and on-call schedule that required 80 hour work weeks. Either I got the work done or they wrote me up for missing deadlines. I would have left but I had no other job to leave to (there was a recession, remember). As soon as an opportunity presented itself, I was out of there.
