Security works in layers. There are two layers before the passenger screening at most airports, and at least a couple after screening. You don't want your last line of defense to be the only one.
The problem with the Solyndra system I saw was the white roof was a dark grey due to dirt and dust, and it had been washed down a few days before our visit. Agree on the political aspect... but I think they were so screwed up that success was never likely.
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.
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.
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...)
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.
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...
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.
Don't know all utilities tariff books, but it is common that their rate schedule applies only when they are the single source of electrical power to the property.
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.
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.
I agree several thousand-fold. Unfortunately, it didn't and is now pervasive. People have electrical outlets with them built in... There is something to be said for a bad, yet pervasive standard.
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.
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?
Pretty good with finance, actually. Tell me, what is a "safe" rate of return today? (Hint-- no where close to 4%.) What does healthcare cost for a 50-year old + family as OP indicated? What are annual property taxes on that paid off home? How much of that savings is in cash?
My math would be as follows: greater of $200k or 5 years spending in cash, 2% safe return (but hopefully 5% some years to allow for a splurge here and there), $1,000/month for a basic health insurance policy, $250/month in property taxes. That puts basic income requirement around $20k/year, and most people like to eat and stuff, so call it a minimum of $25k for a very frugal lifestyle. $48k Makes things reasonably comfortable.
$48k/$1MM invested requires a 5% rate of return until you are eligible for social security, when hopefully an extra $2k/month + Medicare kicks in and let's you live on 2-3% per year. BUT, you still need a separate nest egg for medical emergencies, say an extra $50k that hopefully grows by 2% per year for when you get really sick.
Retirement is expensive even if you live frugally. Most people are better off keeping a low stress job a few extra years to cover medical and help slowly build up cash reserves. Unpleasant surprise paying capital gains tax on that cash reserve all at once. Also unpleasant surprise when you switch from a historically high-growth portfolio to a dividend based portfolio when you have a lower risk tolerance. I might have become overly conservative now though...
Not to be Debbie Downer, 1.2MM is rarely enough to retire early on, even with zero debt or college costs, unless you live on less than $1,500 per month and plan on down-sizing the home soon to boost savings.
Personally, I like working, so I don't mind spending 10-12 hours a day at the company I helped build. The money is good, wife and I don't have kids and like to travel, so it works. I get about 6 weeks of vacation a year, although most of it is in the form of long weekends. We cut back on our pay and proportionally reduced the stress level, so a long day isn't always long hours working.
I look at my Scandinavian sister-in-law, and while I might envy the month of July off and zero-work weekends, I prefer what we have more. (Although I will need to retire hopefully around 50, I liked the retire early, retire often strategy more.)
Personally, liked Sense8, but to each his own. House of cards was an expensive series to produce, but it pays dividends now with justifying the strategy.
What I dislike is that some series just don't last. I really got into Straights or whatever it was called, but it only made it a season or two. Common problem; hope Netflix continues to support the long tail.
When the third party content cost approaches parity with Netflix original, we should see more come into play. For now, it seems to help subsidize a lot of foreign content, which may be good for the world.
Presumably, they would be boxed, from the printer, or in individual envelopes or something "neat and tidy" as a business transaction. Compare that to a random bag of different gift cards that have been concealed.
I don't fully understand the significance of the police officer scanning the a card in his cruiser; I would have thought that would show a mis-match between the two credit card numbers at least, even if it couldn't get extended information.
I mostly agree, up to the point that they are considered evidence of a crime. Reasonable procedure might be to scan a random sampling of say 5 cards and use the results to obtain a warrant for the remaining cards.
Without a warrant I don't understand how the evidence could be admissible.
The thing is he didn't expose any corruption. If he had, I would have considered it at least.
What he exposed is the fact that Hillary is a politician and as such politicks, and that some of her staff members put things in email that they should not, expressing non-professional attitudes towards others, including donors and other politicians.
I am perfectly at peace with not shooting the messenger, but this crap is just petty gossip. I would have felt the same way if the words came from Cheney.
That seems like an odd statement. Most entrepreneurs I know start when things are bad, not when they are great-- partially out of necessity, but primarily out of a high level of risk tolerance. You give up when things are good, and you can easily get a job making nearly the same amount of money (or more) with less stress and pain.
The things I see keeping people on the couch are drugs and alcohol, video games, bad relationships, health problems, lack of purpose, and low self esteem.
UBI hopefully keeps the self esteem issues from being a dominant issue, and socialized healthcare addresses many health problems... but it doesn't make risk takers. Coke makes for risk takers...
Quite true. Bernie would not have been able to win the general election. I don't know what problem would have been the nail, but it would have been too easy to defeat him.
