Slashdot videos: Now with more Slashdot!
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
They currently are offering this service to 25 ZIP codes - likely those directly surrounding a distribution center. However, there are several logistical factors that just seem to make this unworkable to scale:
1. If I place seven orders a day, I alone have monopolized a driver and his vehicle for an entire work shift if the distribution center is 30 minutes away from me. That's the labor cost and vehicle cost for an entire day that my orders must pay for in "shipping".
2. 30 minutes one way trip is optimistic, I live in the 25th largest city, and it took me 80 minutes round trip just to go to a Radio Shack that had an item I needed in stock, 1/3 of the metro area away.
3. Even if there were distribution centers where every Walmart has a store in the US and they had a fleet the size of FedEx themselves (FedEx even just does a daily route), can they really keep the kind of items everywhere that I would order? Today, soldering iron tips, NiMH battery sub-c cells with solder tabs, replacement cherry mx keycaps, other days Loc-tite blue adhesive, 55" 4K TV, USB floppy drive, heat pump valve, that Spiderman comic from 1993...let alone that 80% of the items on Amazon are single-item-only things from marketplace sellers, very few of whom ship their entire inventory to Amazon for safe-keeping.
The challenges here are likely why they are thinking WAY out of the box, like delivery drones.
I specified and owned an EISA system, a rare 486-50 (not double-clocked DX2), with 16MB memory, $4000 or so spent.
EISA is a very odd beast, if you recall the original ISA bus that had jumpers you had to set on each card to non-conflicting IRQ, Address IO, and DMA values, then you will see the "brilliance" of EISA, which had a floppy disk config program for every card you bought to set the bus values. Seeing anyone that still has the matching and required EISA setup disks for their hardware is going to be the rare thing to find.
This is also completely Microsoft's fault. In Vista they decided to kiss the ass of big media companies in order to play Blu-Ray content, which required encrypted end-to-end data transport, mandating the rewriting of the driver stack for everything from video and sound cards to imaging devices and audio mixing. They should have just given them the finger.
What Microsoft didn't have to do was just completely discard gameport support. Microsoft blatantly removed the code to support 15 pin gameports from the OS. In Vista 32 bit, it could be partially put back by driver hacks of old dlls, but that hack was made impossible in win7. You could literally buy joysticks at the same CompUSA that would not work on the Vista shitboxes they were selling.

Reading glasses, those off-the-shelf from a rack with a positive prescription, are not for those that need prescription glasses. They are for older individuals who still can focus at distance, but who have lost the muscles and lens plasticity to focus their eyes on closer objects.
The eye becomes able to focus on a smaller range of distances in older age, and for a person with good vision who has not needed prescription glasses, this might mean they can focus from infinity to 100 cm instead of infinity to 10 cm of their youth, making reading a book difficult.
The majority of those needing prescription glasses are myopic, or short-sighted, meaning that they can focus well on close objects, but cannot bring far objects into focus with their eye's lens. They will never be able to see far objects such as the stars clearly without optical correction. Unfortunately, after correcting the vision with prescription glasses, the same problem also occurs in older age, individuals can no longer bring closer objects into focus while wearing prescription glasses.
Simply taking the glasses off allows for seeing close objects again, but is suboptimal. First, the prescription glasses likely also correct for astigmatism, another type of distortion in the eye's lens or shape. Secondly, uncorrected vision in people that are quite myopic, such as myself at over -4, means that I can read a book when held a bit closer than would seem normal, but cannot focus on 2x24" monitors when they are 0.5m away, computer monitors are too far away to see. I would travel the world in a bubble where only things 15" or closer can be seen without glasses.
When the eye's lens becomes less plastic in older age, this may mean that the 0.5m monitor can neither be seen cleary with traditional prescription glasses or without correction. A second pair of glasses could be tuned for things 0.5m-5m away
The problem with bifocals and progressive lenses is that they assume you are looking down to see close objects. For those that do close-up work, from SMD soldering repair to dentistry as well as individuals working in front of monitors, they are not a good solution, as the work is directly in front of the eyes.
One practical solution for computer work is 40" 1080p monitors at a farther distance. This takes research when subsituting a television, because many HDTVs that one might try to use at 1920x1080 do not have clear 1 to 1 pixels as advertised, even with digital input.
Bitcoin is a currency. Like all currencies, its usefulness is determined by the number of people that you can do business with using that currency. Pounds Sterling also do me little good in the US; limited acceptance depending on venue affects all currencies, not just Bitcoin. Further acceptance like is promoted in the BitPay ads will allow more people to easily receive bitcoins, and then spend them again without any currency conversion.
Bitcoin's value fluctuates against other currencies - that also is a trait of other monies. However, it does have a guarantee that other currencies don't - it won't be printed by the billions to pay off government debt and devalue savings.
The bitcoin is international - it sees no borders and eliminates the extortive money exchanges required to buy goods in other countries. I can buy merchandise from Thailand or Peru on the Internet, and never have to worry about what their local money is. My Bitcoins will buy a coffee in a coffee shop in Kabul or Tokyo just as easily. Likewise, I can sell on the Internet without discrimination; I don't have to worry about fraudulent payments and can ship anywhere in the World.
The huge difference is that Bitcoin has a built-in money transfer mechanism that government-issued currencies do not. Government money requires third-party systems like credit cards and checks, which allow forgers and criminals to suck money directly out of your bank account, causing significant grief. The only way this system remains viable is that credit card companies pay for theft out of their profits or take the money back from the merchant that was victim of the poor security of credit cards.
Bitcoin does not allow Soviet block hackers or card-skimming waiters to take your money through simply stealing your credit card number. You must authorize and "push" every payment to the merchant. Making one payment reveals nothing about you and does not allow the receiver to take more unauthorized money from you. There is no bank to freeze your funds or government back door to empty your account. You are in complete control of your money.
The biggest impediments have been using Bitcoin software and obtaining bitcoins, followed by the capricious exchange rates. All of these categories have become better excepting the government war on exchanges, funded by bankers.
If you are working in a place that fixes computers and is an A+ shop, like using in their marketing, then they need to have 50%+ A+ certified techs. If the person hiring you only has an A+, then they might consider you in their club.
It's still just one more letter code that can be in an HR resume keyword search, and it's dead simple. It uses adaptive testing; I scheduled the first 90 minute test, and by answering every IRQ question and other bits of impractical knowledge, was done in about 15 minutes. The test administrator asked if I wanted to take the second of the two - another 15 minutes once the machine figures it can throw the hardest questions at you and get them answered. Computer repairman are going the way of stagecoach repairmen though, although it's one thing that can't be off-shored...
That being said, any single Microsoft IT test is cheaper, and just having one lets you say "Microsoft Certified Professional". If there is a closet of Microsoft stuff in a server room that would make this cert appealing to a company, I would dread the daily grind working there.
For the rest, there's still the independent site mapping which Starbucks are currently open."
