Comment Perhaps, but different requirements. Origin for ex (Score 1) 237

You make a good point.

On the other hand, UPS and FedEx are deisgned for any customer to send any type of package from anywhere to anywhere, using any of many services. Amazon's will be designed for only Amazon to send packages from the places they choose, and they need not deliver everywhere - they can have UPS deliver to small towns for them. Amazon doesn't need to ship those cookies grandma made for you and she's shipping from Tiny Town, Colorado, paying by check. Amazon Shipping will have one customer sending packages, and sending only from Amazon's warehouses, using the standardized box sizes that Amazon chooses.

There may be enough differences that although Amazon can't make a better retail shipping company, they can make one that works better FOR AMAZON, for some packages. You may have seen the back of a UPS truck looks a bit chaotic because there are all these different sizes and shapes of boxes. On Amazon trucks, they'll all fit neatly and efficiently on the shelf, with one medium box being exactly same the same size as two small boxes.

Comment "Warrior" does mean taking sides (Score 1) 391

No doubt some Palestinians got a raw deal in 1967. Now their grandchildren are bombing schoolkids, hospitals, and paramedics. Neither group is the good guy in that conflict, if you look at it with any intellectual honesty.

As far as "most people concerned", voting suggests that most in the US support Israel, though some support the Palestinians (most of *those* do in fact prattle on about the Jews' conspiracies to take over the US), and some see that two groups killing each other is just bad all around.

It seems to be the nature of warriors, Social Justice warriors and most other kinds, to always take sides. In this case, they've picked the Israeli side. I find that neither surprising nor inconsistent with their core world view that the world is full of weak victims who need a SJW to ride in on a white horse and save them.

I'm specifically saying NOT we you describe in Canada, NOT this:

>> Did you know that hospitals and clinics in Canada don't even have POS systems or cash registers?

Insurance covers unexpected high costs, NOT routine, day-to-day expenses. Consider home insurance. You use home insurance if your house burns down, or floods, not to change a light bulb or fix a leaky faucet.

I can afford a $25 visit, for a flu shot or whatever. That's a routine, expected day-to-day expense. I used to pay for $25 and that was that. Now, the flu shot goes through multiple levels of huge bureaucracies, so it has a total cost of $75-$150 an it takes three months for the doctor to get paid.

Comment No, ADL actually DOES "fight for social justice" (Score 1) 391

I think you misunderstood. GP simply said that ADL is a bunch of social justice warriors. That's entirely correct, according to ADL. He didn't "blame" the SJWs for anything, he said ADL is SJWs, and it is, they say they are. A few references from the ADL web site for you:

Comment DSL dedicated for about 1,000 - 2,500 feet (Score 1) 227

Cable is actually a type of DSL, but here we'll talk about phone-line DSL. There are many, many versions of phone-line DSL. IDSL, CDSL, and DSL Lite can provide about *up to* 1 Mbps for absolutely no more than 18,000 feet (2.5 miles). VDSL has an "up to" bandwidth of 51.84 Mbps, with a maximum distance of 1,000 feet.

So basically you have a DSL connection between your house and the end of the block. At the end of the street, your DSL connection ends at a DSLAM, where it's connected to a segment shared by you and your neighbors.

The SLAs have three costs associated with them. As you suggested, they may have higher repair and maintenance costs, because problems get fixed faster. Rarely, the ISP may have to pay out on the SLA. More importantly, bandwidth usage is very peaky - demand is much higher than average for short periods. If I have an X Mbps line, I can use that to provide X Mbps to 1 customer 100% of the time, or X Mbps to 10 customers 99% of the time, or X Mbps to 40 customers 90% of the time. In other words, the ISP can serve many more customers per fiber if congestion is allowed occasionally, during peak periods. There's a big cost difference between "you'll have 10 Mbps dedicated to you all the time" and "you'll have 10 Mbps most of the time, but it may slow a bit during peak hours".

Comment Lower than you'd like, available bandwidth is used (Score 1) 227

I have no doubt that your cap is set lower than what you'd like it to be. Hopefully you have the option to upgrade by paying $10 more to get the plan you want, or a new competitor entering your market.

> arbitrarily and artificially low, compared to the available bandwidth.

During peak times, available bandwidth is in fact pretty well saturated at many points. If it weren't, ISPs would be stupid - they would have spent money on equipment that they didn't need, and aren't fully using. The ISPs aren't stupid - their marketing departments may be a bit slimy, but their engineers know how to provision a network.

Comment It's the law (Score 1) 317

> SOME employers. Many do not. Or many only partially pay.

There's a little law here in the US that says employers MUST provide health coverage for full-time employees. If you're not aware of the Affordable Care Act, no need to try to discuss the finer details with you.

What kinda pissed me off about ACA is that I preferred health INSURANCE, not a comprehensive health *plan*. You know, insurance, a system that covers unexpected high costs that I can't readily cover out-of-pocket. ACA basically made health *insurance* illegal, now everyone has to pay for "the system" to handle a $25 flu shot, doubling it's cost.

> I've only tinkered with it in VM environments but I would like to give it a spin as an offsite backup sync solution.

In all my years on Slashdot I've never done this, but since you said you would like to give something like this a spin:

We've spent many years developing a pretty bad ass offsite backup solution based on this concept. One reason it's bad ass is that I found some cool ways to make it very efficient (cheap). You can boot up your backups live in our DC and SSH to them (or however you like to access them, they are exact replicas of the original, other than IP address). If your need is enough that you might be interested in spending about $30 / month for a really nice solution, let me know.

Comment multiple files, or drive images as logical volumes (Score 1) 156

Of course if that "large amounts of data" of data is multiple files, rsync doesn't have to read the unchanged the files. It can see by the file modification time and size that it matches the remote copy.

You mentioned ZFS, and offsite backup. For our business grade offsite backup and hot spare, we use LVM (logical volume manager). If you have a very large file, particularly a drive image, you'll get significantly better performance by creating it as a logical volume rather than as a file* on another filesystem, and LVM can easily list the blocks that have changed since the last snapshot. In fact, you don't even have to list the blocks, you can just transfer the copied-on-write parts directly because they are stored as a separate volume.

* A logical volume is of course still a file, because on *nix everything is a file. Whether you call it /home/ubuntu.img or /dev/mapper/images/ubuntu, it's a file either way, and you can do file things with it. By skipping the step of putting on ext4 filesystem underneath to hold this large file, you have less indirection and better performance, as well as enhanced data recovery options if bad things happen. (Having a filesystem inside another filesystem tends to confuse some data recovery operations).

$6000 on the government spending PERSON (plus $500 out of pocket). You probably have either kids or parents who are paying very little tax, if any. Guess who is paying the $6,000 each that they cost? It ends up roughly $20,000 per payer, per person employed full time. That is, each person currently paying pays an average of $20,000.

> that in USD, I would have an annual take home pay of $132 extra living in Texas

Employers provide health coverage in the US. It's not part of take-home pay in either place. In both places, the bulk of the cost is not seen by the consumer (which screws things up), with some incidentals like non-prescription medicine paid for from take-home.

The systems are actually quite similar, just basically in Canada the government runs the one and only insurance company. The only major difference is that in the US you have more choices you make, there are different plans to choose from. Here's something that would be really different:

My wife and I were referred for MRI scans. Since the cost wasn't paid out-of-pocket, we didn't care too much what it cost, but I did ask, for reasons that are slightly off-topic here. The place the doctors referred us to charged $2,000 apiece. I took 5 seconds to do a Google search for "MRI Dallas" and cAalled the first place listed. They said $1,200, but only $1,000 during off hours, and $650 if I filed the insurance form rather than having them handle it (which means they get paid immediately from my HSA). From $2,000 with the "normal" method that 99% of people do to $1,200 just by making one quick phone call! Another $200 saved if I came in after work, when they less busy. That's fully half the cost saved. What if there were a system that encouraged people to cut the costs in half by making a phone call and scheduling the appointment for 5:30, when they get off work.
