Comment Re:Reality (Score 1) 92

Do we really know beyond what Google is saying? I don't have a horse in the game, but...

I have seen competing utilities move each other's lines. It leads to an undocumented mess of cables that are less reliable and harder for a future party to add to down the road. Nobody is responsible for pole loading, and things break.

There is something to be said for "I got here first, so go pound sand."

Now, if the pole-owning utility had and has standards in place dictating where cables Shall be installed, and they are not in those locations, notice should be sent to the tenant utility requiring them to relocate within xx days, and/or pay a substantial penalty.

The bottom line is that the poles are not public domain.

Comment Re:The scanning bit isn't the problem (Score 1) 106

It seems to me that most of the slowdown is at the X-ray machine, with the operator running 25% of the bags through back and forth at least twice. Ignoring that, each lane should be able to process about 5 passengers per minute. Better binning/de-binning lanes should double it, and one scanner per X-ray would get you close to 15 people per minute. If a typical narrowbody has 150 passengers and a 40-minute turn, that would put you at 4 gates per security lane... and about 5 minutes per passenger to go through the process.

In the scheme of things, not too unreasonable.

Comment Grid Scale Batteries (Score 1) 108

Letter also indicates they installed a 20MW/80MWh battery at SCE's Mira Loma substation. (I think there is a 100 MW gas peaking plant there too though...)

Would be impressive if it wasn't for the fact that Edison was the only place I ever saw Solyndra solar cells before. (Looking at the installation, no wonder they went bankrupt...)

Comment Re:Secure the gateways (Score 1) 346

Honestly, these types of systems are going to be inherently insecure, and I doubt you could make a meaningful security improvement.

What should happen is an easy, secure, simple VPN setup that doesn't force users to navigate to a cloud hosted service for remote access, and blocking internet access for devices by default. History has shown this is too hard though.

Comment Re:How do we prevent flooding the phone system? (Score 1) 346

The phone system isn't especially well protected from this; it wouldn't take much to take over thousands of SIP accounts and do the same damage today, and it had been done in the past as well.

Mental note: change all of our phones from a SIP password of 1234 to something more secure... even though external access is not allowed...

Comment Re:Whats the point? (Score 1) 81

Yes and no; a 2-axis tracker makes better use of the sunlight and the PV panels, yes. It also makes for a better production profile, giving more production closer to sunrise and sunset, and a more even profile throughout the day. But, panels are cheap, and the trackers end up costing as much as the panels... so the return is really that shoulder production time.

The transmission lines are efficient, but don't scale especially well. The utility primary substations are a major choke point. Distributed generation as the primary energy source requires less centralized infrastructure and can be substantially more resilient.

But, either approach still needs evening/night production sources. These seem to be more practical in a distributed model if you want storage, and centralized for generation.

Rooftop solar is good energy policy: domestic, local, distributed. Add in on-site storage, and you have a real winner, as the maximum solar penetration can safely go from 15% to 45% of peak load(/circuit capacity). For bonus points, add in pollution, and fuel cells even start to make good sense at a reasonable penetration. I am working on a couple new buildings now with a combined PV system of about 1MW... for pretty small buildings in the scheme of things.

Net Zero is coming...

Comment Re:Not happy at all for a "Pro" laptop from Apple. (Score 1) 315

Any time I am using my laptop for work, I need Ethernet, HDMI, 2xUSB-A, and power. I lived with the compromise with the Air by having Ethernet dongles everywhere and not using it as my primary workstation in the office-- so I could have the portability. If this is where Apple is going, the pay really don't have a product for me anymore. I don't want to travel with a dock that needs an external power brick.

Comment Re:Film at 11. (Score 1) 315

While I don't agree with it, USB-C is supposed to unify Thunderbolt and USB in the next generation of processors IIRC. It is functionally logical to have a USB-C port on either side of the laptop and be done with it.

It will then look very pretty and symmetrical on the sales table. It will work well for 70-80% of the use-cases out there with one or two extra dongles. If you aren't in that category, you are out of luck because all the manufacturers will go this direction soon.

And, they get to create metric shittons of e-waste as everyone is forced to throw out all their old power supplies, chargers, and other stupid dongles.

Comment Re:MagSafe have save me tons of money (Score 1) 315

In fairness, it isn't always possible-- think meeting rooms and the like. MagSafe also makes plugging the adapter in a little easier one-handed.

Personally, getting rid of USB-A ports would keep me from replacing my MBA. Dongle Mayhem pisses me off, and if this is where they think they should be going with their laptops, they aren't for me. I fully understand the concept of a USB-C dock, and it isn't a terrible approach. Problem is when you aren't at your desk you end up bringing a second bag roughly the size of your laptop in order to be able to use a flash drive, Ethernet, external display, and power adapter. I am also a bit pissed off for having to buy all these stupid single-function thunderbolt dongles, but that is the Apple way...

Do these people not understand that wireless really sucks for some things?
