  1. Re:30 bps on Mac Sales Declined Nearly 10 Percent Last Year (9to5mac.com) · · Score: 1

    If you have a 12% share (or interest rate, or anything else expressed as a percentage), and it goes up 2%, what does that mean? Is your new share 14% or 12.24%? If your 12% share goes up 200 bps, your new share is 14%.

    It is to remove ambiguity, but not that one.

    If you have 12% market share, and your share goes up 2%, what does that mean? Is your new share 14% or 12.24%? On the other hand, if your 12% share goes up 200 bps, your new share is 14% - no ambiguity.

    Would a person notice and react in the same way? If they are even semi-competent to be driving, yes. If they belong to either the 'stare directly at the car in front of you at all times' or 'my phone is so much more important than driving' camps, then no.

    Around here it is pretty common for bystanders to take on the role of 'flaggers' around an obstruction until emergency equipment arrives. The 'obstruction' could be an injured (or dead) animal in the road, debris, an accident, a fallen tree, you name it.

  6. It is different. If you can't steer you can't get off the road. That is a completely different situation than being stranded on the side of the road.

  7. Yikes! So we replace the scenario of 'driving down the interstate, electrical failure!, steer to the side and stop' with 'driving down the interstate, electrical failure!, stop in travel lane, exit vehicle, find little metal bar, attach wherever it needs to go, get vehicle moving (or push), steer to side of road'.

  8. If your car has a problem today (say, electrical failure) while you are moving you can steer to the side of the road. If your car has a problem today when you are not moving someone can push your car while you steer it to the side of the road. Neither of these are possible with no wheel, you are going to be sitting IN TRAFFIC with no way to move til the wrecker gets there.

    He is correct, assuming you itemize deductions. A $1000 donation reduces your AGI by $1000, with the net result that you do not pay taxes on the $1000. And you certainly DO pay taxes on corporate gifts, because the value of the gift is reported on your W-2 as ordinary income.

    You are confusing two different things. Pollutants are measured in PPM. This makes sense - it doesn't matter how they got there, they are still pollutants. Emission standards, however, do not measure PPM. For light duty vehicles standards are specified by amount of pollutant (mass) per vehicle mile. For heavy duty vehicles they are specified by amount of pollutant per hp hour or something similar.

    Maybe a 3081 (dyadic), 3083 (uniprocessor), or 3084 (quad), but not a 3082. 3082 was the Maintenance Support Facility for the above machines. And 3087 was the coolant distribution unit, and 3089 was the motor-generator to create the 400Hz power.

  18. Be serious. That thing is a total sham. Look who is in it - all the big states that normally vote the same anyway. Since it is practically impossible to win the popular vote without winning those states they have nothing to lose by being in this 'compact'. But, just in case, they stick in that little 'but only if enough other states do it' clause, which they know will never happen (because the other states DO have everything to lose).

    If you think NY would EVER convert votes for democrats into votes for republicans just because other states did, I'll have some of what you are smoking. If that were to ever actually happen the legislature and governor would be replaced so fast it would make your head spin, and that would be the end of the 'compact'.

    It will never happen because the Constitution specifies that the president is to be elected by the states. The only way to change that is to change the Constitution, which would require 38 states to decide they should have no say on who is President, that whatever a handful of northeastern and west coast cities decide is fine with them. Ain't gonna happen.

    Blockchain is not bitcoin. The only thing computationally expensive in blockchain is an attempt to forge an entry. The expensive thing in bitcoin is the mining operation - there is no mining operation in blockchain. Blockchain is a template of what data is associated with something, and controls on who can see and modify portions of the data. There are 'smart contracts' which specify what parties must agree to a transaction (consensus). The stuff is all controlled by encryption, and does not rely on a central database.

    Of course it isn't 'the only' way to do it. There is seldom only one way to do anything. They could do it all on paper if they wanted. They don't have to justify anything to you - they just reached a business decision that this is what they want to do. I would like to hear your reasons why you think it is 'overkill' though.

    'Fluff' is claiming this could be done with 'a bunch of simple database joins'. For even a simple food product (say a bag a salad) there are many different companies involved. Farmers, trucking companies, processors, packagers, packaging suppliers, wholesalers, distribution centers, retailers. All with their own databases. All with their own database designs. All with their own database managers. All with their own database versions.

    Yeah, I guess it would be pretty simple to just get authorization to all those databases and whip up 'a bunch of simple joins'.

    Decentralization is precisely the point. A farmer may sell his crops to dozens of buyers. Whose database is he going to update to say which field this particular truckload of lettuce was grown in? One of those buyers may make pre-packaged salads, provided to dozens of wholesalers. Whose database are they going to update to say which truck supplied the lettuce, and what factory/date/shift processed it? Whose database does the trucking company that moved the product to a warehouse update? What database does the warehouse update?

    Today, the answer to all those questions is 'their own'. This is why it takes long to figure out the source of something. Retailer has to ask wholesaler to look up where they got it. Wholesaler has to ask packager where it was processed and when. Packager has to ask farmer where it came from, etc. With blockchain, that is all unnecessary, the whole chain is available at every point.

    You are missing the entire point. The point of the blockchain (regardless of how it is identified) is that you have the ENTIRE HISTORY of that product in one place, and that history is cryptologically secure. Even if that one product had 5 steps in the supply chain, it is ALL there. Your magical UPS barcode tells you nothing except what UPS knows about the package. That is a HUGE difference.
