Comment Re:Correcting myself (Score 1) 668

The standards for speed limits and such are set by engineering standards.

Your general point is correct, but this detail is lacking, as it's substantially more complex. Speed limits are generally regulatory, and the road is designed with the regulatory speed in mind. Engineering judgment, backed by a speed study, can be used to set the regulatory speed, of course. The regulatory speed can also be modified by driver behaviour and politics. A few years ago, the speed limit on parts of the Rich and the Glenn was increased because of driver behaviour, even though many of the curves, both horizontal and vertical, were designed for 55 MPH.

Convince the board to change the standards, and essentially, you've changed the law.

Sort of. Many standards are set by local municipalities. Anchorage, Valdez, Fairbanks and Juneau all have different requirements for design snow loads, for example. The State has adopted the 2014 NEC for electrical design, but municipalities can modify it at need. The DOT sets the design standards for roads and highways, as allowed by statute. The board can recommend, but it's much more concerned with behaviour, ethics and competency than it is about the design standards.

That is a NATIONAL licence.

Not quite. If you have license to practice in Oregon, that's the only state in which you can practice engineering. If you're registered in one state, you may be able to transfer your license through comity between the states, but that's not assured. For example, in Alaska, you also have to pass a class in Arctic Engineering to obtain the PE here, even if you're registered in Oregon. Washington requires that you work for longer under the supervision of another engineer than most other states. California requires that civil engineers pass additional exams covering seismic principles and engineering surveying.

The NCEES maintains, if you wish them to, a record of your licensure, including college transcripts, exam results, work experience, et c. that can make registering in multiple states easier.

The two exams that you have to take are the FE (Fundamentals of Engineering), and the PE (Professional Engineering) exams.

Is this due to the extensions you're using, perhaps? I'm fairly certain that Firefox hasn't been shut down or restarted since the last time it was updated. The only think that ever bothers me is its complete unresponsiveness when it's loading a large PDF. I'm pretty sure that my trouble started when I started using the decentraleyes extension, so I choose to live with and wait out Firefox's pauses.

I was also talking about working conditions. A lead-acid battery can work decently well in conditions right down to -60F. I've started a car that was stored in conditions that will leave the lithium-ion batteries as useful as a brick. (A few days ago, my wife's car started at -25F (~-30C) without any heat to the battery or engine.) About 15 years ago, I was working on a power cart intended to provide continuous cathodic protection to a pipeline in arctic conditions. We were able to design the system so that (with a small margin) the batteries could be stored outdoors without additional heat down to temperatures of -70F. Again, these are working conditions at which lithium ion batteries can't be made to work without difficult and potentially costly adaptations. You may think these fringe cases, but for me these are quite common conditions.

. . .and yet the electrolyte in a fully charged lead acid battery doesn't freeze until about -90F (~-65C). The battery continues to provide lesser current down to the freezing point. I can personally attest that there's enough juice in a good battery to start a car at -55F without either having been warmed or charged. (I only started a car that cold once.) My wife forgot to plug her car into the timer last night, and I started it this morning at -25F.

Lithium-ion batteries stop functioning at -40C, and are pretty useless at temperatures below -20C. Despite the recommendations you cite, lead-acid has a safe working range that covers a pretty darn wide temperature range.

p.s. I went looking and found a pretty chart for you: The chart shows a slightly lower freezing temperature than I recollect.

Go to the macsales home page. Don't click through to the detail page that the image of the product links to, though. Go ahead, I'll wait.

On the front page, and only on the front page is a picture that shows a little bridge joining one of the Mac's ports with the DEC. Every other picture that I've seen omits that little detail.

Happy now?

The Amsterdam foot (voet) consisted of 11 Amsterdam inches (duim). It was more complex than just 11 inches to the foot, though: Dutch feet varied from 10 to 13 inches depending on local laws. The variability in units of measure varied this way throughout Europe.

Comment Re:Why avoid again? (Score 1) 84

My wife and I both have an iphone 6s and use different carriers. I'm on a regional GSM carrier (GCI) while she uses Verizon (CDMA). We occasionally travel to Chena Hot Springs, where there is a single CDMA tower owned by GCI. (GCI recently bought the Alaska Communications System cell network, which is CDMA.) My wife has a signal, while I have nilch. I won't call this confirmation that a t-mobile phone won't roam onto a Verizon CDMA network, but it's suggestive. Isn't the spectrum also different?

Ha! I'm still running a 9 year old Q9400 as my desktop, and a 14 year old AMD CPU is taking care of media. Neither of them are fast, but I also prefer Linux. (Windows is there for a few games, Rosetta Stone and to back up my phone.)

I must admit, though, that I'm thinking of upgrading. I'm a bit disappointed, though, by the news as I was thinking of a nice, shiny Zen processor in January and I'd prefer to stick with Window 7 for now. I find it easiest to keep my Windows version in sync with what's prevalent at work. Ah well; maybe I'll just dump Windows and figure out something for the little bit I use it for.
