Most power is redundant and the big places have backup power these days. Twenty years ago you could theoretically go without power for a day or two (POTS lines at least gave you a lifeline).
Nope. Anyone with a shovel and a knowledge of these systems can cause all sorts of havoc.
Cut the right fibers in the right places and you can make life miserable for a number of carriers. Especially for those running "slightly oversubscribed" IP networks.
You mean where the telco designs out a fully redundant system (physically diverse entrances into different COs/POPs with layer 1 protection) and the customer says "whoa, that's expensive...I think I'll just order two circuits from two carrier and not tell anyone that I want those diverse..."
It's not funny as this happens "all the damn time..."
The nice thing is if you want a more recent update, just start calling all of the people on Slide 6. Then again, this is a four year old presentation...some have probably moved onto other positions.
Fifteen years from now food shortages, triggered by the combination of climate change and population explosion, will impact significantly on even advanced western societies. Crops will fail widely, on a regular basis. The cost of food will be relatively a lot more than it is now, and the availability of it a lot less dependable.
You mean the same crop shortages that were going to faminize the 1980's...or the 1990's...or...
There is little chance of that happening in the US, come live out here in the corn belt and even with the OMG, IT'S THE DUST BOWL ALL OVAR AGAIN!!!! and you will see that farmers will grow crops that are drought AND reasonably flood resistant (and with easy to install drainage tile...the latter is moot anyway!).
People also tend to forget that countries like India and China use manual farming techniques since there is a LARGE amount of unskilled labor there who is willing to do the work cheaper than a gallon of petrol. Once wages rise faster than the cost of a gallon of gas....then you will see modernization of those agri-businesses and yields will substantially climb.
PHB's are the only reason why we keep building offices for a sizable percentage of the population. Yes, you will still need to see warm bodies for a variety of things, but in reality office jobs can get done with a variety of current tools and probably more efficiently without having to pay for large buildings, parking lots, etc.
Yes, businesses will need a place of "business" for meetings (there is a net-benefit for face to face/socializing/etc in a controlled environment) but for the rest.....ehhh, crack that work/life benefit up to 11 and have my people login when they can and work their asses off for me while I don't have to pay to keep a building empty 13 hours a day and 24 hours on holidays/weekends.
First thing is to ensure your monitor can tilt far enough whether sitting or standing. Most can, but it's a good thing to verify first.
After that, it's simple. All you need is a stand that can hold keyboard/mouse and then tilt the monitor to what is comfortable. I built mine out of a $12 piece of bookshelf board from Menards. A few drywall screws and then you can pull it when you need to sit down.
As a telecom employee, I'm getting a kick out of these....nevermind.
Anyhow, the process for burying lines is pretty straightforward. Look at any relatively new subdivision or business district. Do you see any poles? Probably not. Because most utilities WANT to bury lines. It's easier and looks better and most governments now request/mandate burying lines.
Now, try to do that in an older neighborhood. With water/sewer/gas/fiber/copper/old steam pipes/etc. Try getting locates done in a busy older neighborhood. Oh, and in order to bury you are going to have to give some yard space to put in a ped. Watch people flip out as their front yards are shredded by boring machines (if they are lucky....) or that now there's going to be a slew of pads in their lilac bushes.
When I was back in HK back in 2007, I toured Wing Lung bank and was amazed at the number of people employed in that bank. When the stacks of paper that flowed through that place were taller than the people going through them....
Yeah, plenty of jobs for paper pushers....
Bought a chunk of wood at Menards and built a keyboard/magic trackpad stand. Originally it was designed for two keyboards, but now essentially down to one machine. Install/Removal takes about ten seconds, weighs about 7 pounds. Ugly? Yes, but quick and easy to switch around.
If you mean "The actual amount of uranium that underwent fission", then you are correct. However I don't know of a device that can reach 100% efficiency in prompt fission event. I think you'd probably have more fun with the Americium in the core than the HEU (I think the critical mass for Americium is under 6kg). That's a lot of smoke detectors....
So it's grab a ride if it's heading your way which seems pretty bad since it's completely unsteerable and would be epically cold from no heat source. Plus the delta-V to land and take off from it.
The ones who don't care about building their own core competency usually outsource to a myriad of companies. While they get their work done at a reasonable price, it also means they get a lot of hold music when something breaks. If you have a server/network link that could break and it would require an explanation to the board...you're probably better off having someone in house who can fix it quickly (and find other problems before the big ones go BOOM).
That usually doesn't happen in sub Fortune-1000 companies.
Very few districts have problems procuring IT parts. Remember the Universal Service Fund? That was specifically designed to give money to schools to build this sort of infrastructure. I am sure every district got a piece of the pie. Yes, it was supposed to originally go to rural/impoverished schools...but that was changed mid-session and then everyone climbed onboard to spend those hard earned dollars on....microwave links for schools....video conferencing gear.....Cisco 7600 routers....modem dial pools....you name it.
Schools don't buy at $500/machine prices. They buy at $1k+/machine prices....I've seen their "discounts" and it's usually pretty appalling. I was invited by my local school corporation to buy at their "discounted" rate which was (for a similarly specced machine) 40% above sale prices.
But they spun it as a 50% off of "LIST" price....
I have seen school districts want to build their own fiber infrastructure, build 100MBit microwave feeds between buildings, and demand Cisco TelePresence in every school. And when you look at port utilization, it's around 1%avg/3%peak. I also doubt that the current IT budget hasn't been replacing computers for the past five years as they breakdown, etc.
This is a bond issue, not a budget issue. They want to specially finance $45 million into a district of 17k kids to "build for the future".
As a telecom geek, I see many people create these vast, incredibly complex networks that end up being more difficult to troubleshoot and manage because they invoke non-standard designs which fail when people wander in and make mundane changes. And then when these links fail, go down for maintenance....surprise, there's no 100% network availability.
Three simple rules to networks...
Simple enough to explain to your grandmother.
Robust enough to handle an idiot walking in and disconnecting something.
Reasonable enough to be able to be maintained by Tier I staffing.
Also throw in the fact that SpaceX is NOT incorporating reusability into their price points (from what I have seen, the boosters are designed to be recoverable but the cost structure isn't built around that being an expectation for each launch)...and now all of a sudden the price point becomes lower. Musk said recently the propellent costs for a Falcon 9 launch were around $150k. If he can get a 50% reuse rate of of his boosters, that's a hell of a cost savings AND drives the cost to orbit down much lower.
When SpaceX and Bigelow meet in orbit, that will be an important date in spaceflight. Two wholly private ventures meeting in orbit.
Now if someone could just throw enough coin at both of them to undertake a Mars mission...

Most likely a disgruntled field tech or contractor who likes making people miserable or a field crew who wants to make significant overtime.

Agreed. Some of these cables are 600+ count fibers or are multiple bundles within the conduit.

And of course U-238 "can" obviously capture neutron to transmute into Pu-239. Imagine the joy with that.

Who else had one of these for easy, "on-demand" neutron generation. Bell Labs? IBM?
Could you imagine the poisoning of he ecosystem from all of the pulverized gallium, cesium, and other toxic elements from a destroyed solar plant
Googling is good for "how to" do something, but not so great when it comes to troubleshooting.

Your going to need a whole lotta lawyers. :-)
