How did they get the work done on time? How many people were involved?
11,500 miles/track is around 32 million railroad spikes that have to be pulled and respiked in the new location. If it takes one person 20 seconds to pull a spike and rehammer it in, it would take a crew of 16,000 people working 16 hour shifts to do the work in 3 days. And this is only the guys that are doing the spiking, it ignores the thousands of others that would be involved in moving (and lengthening/shorting curved sections when necessary) the rails, altering the running stock gauge and handling the supply logistics for materials, food, water, housing, etc for these large teams. So maybe 20,000 - 25,000 workers were involved?
To every IT department: you are everyone bitches, we do not care about your concerns shut up and make it work.
YES. THIS. Give me the tools I need to pay your fucking salary and get out of my way.
But you don't pay my salary, my salary is paid by the CFO, who happens to pay your salary as well. The CFO pays me to keep our network safe from intruders, and to make sure that we are compliant with the regulatory environment we live in - SOX, HIPAA, PCI, etc.
If your device causes a regulatory compliance violation, it's your butt that will be out on the street because you violated IT policy, not mine. If you need some piece of technology to get your job done, convince my boss that you need it and that it's worth the cost to support it. Or convince my boss that you're able to meet all of our regulatory rules on your own - and make sure you have the documentation to prove it.
If we wan't to go this route, I'm obliged to add that no wired or wireless connection can beat the transfer rate of a blue ray. or an external hd.
Actually, it's easy to beat a blu-ray's bandwidth if you're walking it across a relatively large facility.
It takes me about 10 minutes to walk a 50GB Blu-Ray from one end of my facility to the other so (ignoring the time it takes to create the disk), my transfer rate is:
50000 MB / 600 seconds = 83 MB/second
I can get 1 Gbit/second (~ 100 MB/second) from any desktop to any other desktop in the facility (1 gbit to the desktop, aggregated to 10Gbit over fiber, then back to 1 gbit at the receiving desktop). Assuming that I just wanted to get the data between server rooms or IDF's, I could run 10 Gbit over fiber without too much trouble.
No one has "radical life altering procedures" without a positive diagnosis. DREs and PSA are safe and easy. Even the biopsies, while uncomfortable, are safe.
Even with antibiotic prophylactic, around 1.5 out of 100 biopsies will result in infection, bleeding, or other complication serious enough to require hospitalization. Is this worse or better than earlier diagnosis of prostate cancer? Perhaps the American Cancer Society might know something about this and that's why they recommend age 50 for PSA's (with no other risk factors). Public health is not about keeping *you* healthy, but balancing risks across the entire population.
The PSA is not a great predictor of prostate cancer (especially at low levels just high enough to be "elevated"),and the DRE is not always clear either... there are lots of benign reasons for an elevated PSA or abnormal DRE. What is clear is that earlier PSA tests means more biopsies to rule out abnormalities, so potentially more men will die from those biopsies than will be saved by the earlier detection of prostate cancer.
Even though the biopsy is currently the "gold standard" for prostate cancer detection, even a TRUS biopsy can miss many early stage cancers since 6 - 12 cores can easily miss a small cancerous nodule.
Yearly sinus infection. Needs a $8 bottle of keflex to get rid of it.
So i goto the doctor. ($80) And go home with 4 perscriptions. None of which are keflex. ($280)
What used to cost me 8 bucks to get rid of... Now costs $300+
Maybe you just need a new doctor? When I've told my doctor what treatments have worked in the past for me, she generally goes along with it (unless there's a medical reason not to) and gives me what I want.
First, we already know from various scientific papers, that you can use wind energy to provide power for full scale freight trains in Canada, using fuel cell engines, and do so while reducing both carbon emissions and particulate pollution. Economies of scale kick in, you just split the H20 into fuel cell engine components at the wind farms along the route, which also allows you to handle the variable nature of wind.
Can you point to some of these papers? In particular the wind-power one. Large scale wind farms are just that - large scale so I'm curious how maintenance of a thousand turbines fits into the economics. Plus I'd like to see studies about environmental effects of these large scale wind farms.
Second, it supposes that our insane blockade of Cuba and other countries cane ethanol will continue, and that we will continue to divert corn food/feed crops to ethanol with massive farm and energy subsidies that are unsustainable - the most anti-capitalist thing we could be doing.
Agreed - using food crops for fuel is a bad idea in many ways and is likely a net loss in energy.
Third, it assumes that our country won't shift from using mostly air travel (high energy) to rail travel along the dense urban corridors in the East, South, and West.
The graph only goes out to 2030 - there's not likely going to be a large scale shift to rail by then because there's likely going to be the infrastructure. California's much touted high speed rail project isn't scheduled to be done until 2020 at the earliest, and I'm certain that it will be be completed by then (only 9 years from now). There's still plenty of political, economic, and environmental wrangling that will go on before the first shovel hits the ground. And that's just one project among many that would have to be completed before a large scale shift can happen.
I didn't see anything in his presentation about the rare earth minerals that are (currently) needed to produce all of those "green" electric cars. Does the US have enough rare earth reserves to put all of these cars on the road, or will we be dependent on China?
If this tech is so top-secret, why don't they spend some time and build a self-immolate feature into the entire helicopter? They don't really seem to try to not let the tech fall into the wrong hands...
Because you don't want it to accidentally self-immolate in the air when hit by small arms fire?
After many years as an expert carpenter, I've found a need at my current employer for a plumber. I've made extensive use of plumbing in the past both for input and output and know I can handle the work. Many of the concepts are the same between carpentry and plumbing (i.e. cutting things and joining things), so I only need to brush up on the mechanics of how to do it. The pipes in our current building are all old and leaky, so we want to replace them. I have been given an 'unlimited' budget for pipes, tools, etc to set up a small toilet in the basement and after that I plan to replace all of our plumbing. What tools and materials should I acquire? What books should I read? Should I take classes?
Exactly how do you plan on powering electric long distance OTR semi-tractors?
Replace most of them with trains because they cause a disproportionate amount of road damage compared to the tax they pay. Road damage increases with the 4th power of weight increase
Trucks do pay more taxes, but i don't think that an 80,000 pound truck pays 160,000 times more than the driver of a 4000 pound car. Ok, 160,000 sounds excessive, a GAO study says that an 80,000 pound truck causes as much damage as 9600 cars. let's say an average car owner pays just $100/year in road taxes -- do any trucks pay $960,000?
Hybrid cars are great for city driving. In stop and go driving the hybrid trucks and SUVs whomp on the fuel efficiency of my truck, but semi's are going to be doing hwy driving. With little stop and go to get the advantage of regenerative breaking. Without frequent regenerative breaking you substantially cut the effectiveness of hybrids,
But hybrid powertrains have been used for many years in vehicles much bigger than a semi. Surely there must be some benefit?
The problem with the odometer is that it can't be read automatically. People will lie and there can't be enough inspectors to make people actually worry about lying.
All but 13 states require annual or bi-annual safety or emissions inspections. The odometer read can be a part of those inspections.
Although it's not charged by the mile, I'm already paying a tax based on this. Not sure what other states have, but in Massachusetts, everyone pays an excise tax on their vehicles. This is *supposed* to basically be a road use tax. You want to tax my vehicle per miles traveled? That's an issue which will make me very politically active, to start campaigning against you.
isn't a mileage tax more fair? If you buy a $50,000 Mercedes and drive 5,000 miles/year, why should you pay more road tax as someone that buys a $15,000 Honda and drives 30,000 miles/year?
It seems that road taxes should be charged by mile and weight. A fuel tax, until relatively recently, did just that -- typically heavier cars used more fuel. Of course, the fuel tax doesn't charge enough to those vehicles that cause the most damage since road damage increases with the cube of the vehicle weight.
Why would you campaign against a tax that would collect more road taxes from those that use the roads more?
Since liquid fuels (and gaseous fuels like natural gas and maybe even hydrogen) are not going away anytime soon (despite advances in electric cars, there are many people that won't buy a car with a 100 mile range), the answer seems to be to keep increasing fuel taxes to keep revenue constant.
Then when taxes reach a certain ratio to the price of fuel (i.e. when taxes are 100% of the cost of fuel), keep the fuel tax constant and go with an odometer based milage tax. No need for fancy GPS units.
This will speed the move to alternative fuels by making the cars much more cost effective.
Many states already require an annual safety (and sometimes smog) inspection. The last 4 states I lived in had such an inspection. The results are electronically filed with the DMV, so they could presumably collect odometer readings at the same time.
The problem, of course, is how to deduct mileage on private property - a farmer may rack up 90% of the miles on his truck on his own property thus shouldn't be taxed for it (just like he's not taxed on the fuel for his farm equipment).
PCI certification is joke. It's in the best interests of all involved to severely limit the scope of the "certification" - due to cost, time, intrusiveness etc.-
You certainly can limit the scope to only those computers that have access to PCI protected data, but any computer that has access to that data or processes that data is in scope. I'm sure you can configure your network in such a way that allows a breach, but that's not really PCI DSS's fault - one standard can't be expected to provide complete security for all environments....they give you overall security recommendations, if your network allows access to the data by a botnet, then it's your job to fix it, don't think that just because you checked all of the checkboxes on the PCI-DSS checklist that your security job is done.
so only certain areas get tested.
If you're relying on testing to protect your data, you're doing it wrong -- PCI outlines best practices to protect your data, scanning is only one part of the larger picture.
They like to brag that "no PCI certified system has ever been breached" but that's because when you're breached they forensically figure where you violated PCI and retro-actively revoke your certification. It's worse than bullshit it's an expensive fig leaf of security theater.
I've never heard that "no PCI certified system has ever been breached" and I'm pretty skeptical since I know a few ways to get data out our PCI compliant systems. However, If they found that you violated PCI standards, then you weren't really PCI compliant, were you?
They weren't PCI compliant since part of compliance requires applying security patches to in-scope systems, and if credit card numbers were passing through Apache or the web app running on Apache had access to credit card numbers, it was definitely in scope. And of course, storing unencrypted credit card numbers also violates PCI, but even if they were encrypted, if the hackers had control of the application they could have had the decryption keys.
Hey, everyone is telling me that cpu speed doesn't matter anymore, it's all about the cores, so the 8 cpu AppleCrate should be twice as fast as my 4-core desktop machine. The 17 CPU Applecrate II must be blazingly fast! I'd love to see some Javascript benchmarks for that.
So what if my desktop has 2.5GHz CPU and the Apple IIe runs at.001Ghz, more cores is what matters!
Count me in for one that hated the ribbon at first, and then came to like it.
As I mentioned before, we are all in the "They changed it, therefore it sucks" phase with Ubuntu Unity.
Or maybe it's just the plain "It sucks" phase. You can't always explain away suckyness with "Oh, you only hate it because it's different".
I don't doubt that some people love it and will continue to love it, but based on my informal poll of Linux users in my office, many more will hate it and continue to hate it - it's just not a good UI for a large desktop monitor(s).
Though I'll admit to being biased against the "Global Menu". If I wanted a global menu, I'd run OSX.
I don't know if you're being deliberately silly, but Samsung (among others) have designed a phone that appears to be deliberately an iPhone clone, down to quite small details. If you're aware of a phone that existed before the iPhone that most non-techincal users would easily confuse with the iPhone, I'd concede the point. Without debating the rights and wrongs of it, it's disingenuous to try to claim that there aren't a number of manufacturers copying the iPhone hardware and software design to cash in on the market.
Don't you mean that Apple designed the iPhone that appears to be deliberately a Samsung F700 clone?
If Hyperion (among the half dozen or so other companies that want to sell small nukes ) can fulfill their promises, a small nuke can make sense. $50M for a 25MW reactor that lasts 8 years means power costs 3 cents/KWh. Of course, none of the makers have NRC certification so who knows how much the final design will cost, especially when factoring in liability insurance and dismantling costs.
I don't know what commercial rates are for larger power consumers, but 3 cents seems pretty competitive.
The Hyperior reactor at the link I gave is definitely a niche market, you probably won't see one on every street corner, but it's not just for isolated installations since they say that hospitals, universities, etc can benefit.
