  1. Re:The button isn't the problem on Ask Slashdot: Panic Button a Very Young Child Can Use · · Score: 2

    You're asking for a kind of button that will make it possible to rely upon a 2-year-old child as a caretaker.

    That's funny. I thought he was asking for a kind of button that would make it possible for his child to communicate with him as a backup measure, given the video surveillance and all.

    Well, you thought wrong - because he plainly states the purpose is to have the two year old alert him that he needs to check the video cameras and there is no indication of either the existence of a primary alert system or that he is monitoring the cameras with sufficient regularity to serve as the primary alert system.
     

    You're also free to argue that epileptic parents should not be allowed to be alone with their children since their children might be required to be "caretakers," whether via a button, a telephone capable of 911, or merely living within distance to run to a neighbor. Because we'd all support that.

    "Child", not "children" - and really, a toddler, not even a child. (The infant can safely be left out of the "caretaker" equation.)
     

    This is an attempt to shift all responsibility for the parent's care onto the child.

    It's an attempt to shift a significant portion of the care onto the toddler. Anyone with sense would question that.

  5. Re:seems a bit shy... on DARPA's ALASA Could Pave Way For Cheaper, Faster Satellite Launches · · Score: 1

    I don't understand why the idea is being implemented in such a modest manner. The animation has the rocket stage carried aloft for ignition at high altitude by what looks like an F-18. While I don't doubt the performance of the Hornet's engines, wouldn't it make more sense to extend the payload capacity with a larger carrier craft? Say something on the order of the 747-based shuttle carriers?

    Is there a good engineering reason why concepts such as the Soviet-era MAKS was not pursued?

    The F-15 is designed to handle steep high speed climbs, the 747 isn't. The steep high speed climb only contributes a very small percentage to total system performance. (A vital percentage in such a low performance system, but small nonetheless.)
     
    The other reason is that, other than the point solution of small payloads to low orbit, air launch doesn't actually work all the well. The basic problem is that boosters grow bigger far faster than payload capacity rises - which means a 747 only gets you to performance of a 60's era Atlas. (Even if ground clearance wasn't an issue.) This means that an air launcher capable of hoisting a booster with sufficient performance to be useful will have to be a very large custom built vehicle - at which point the putative cost savings go right out the window.
     
    Air launch is one of those concepts, like many perpetual motion machines, that looks very good on the back of an envelope... but which falls apart rapidly once you start running the actual numbers. Which is why, despite being rediscovered to great fanfare every couple of years, significant air launch systems have continually failed to materialize.

  9. Re:Clicks vs Bricks on Radioshack Declares Bankruptcy · · Score: 1

    If I buy a few parts from each of adafruit, sparkfun et al even ground shipping quickly adds up to more than the cost of the parts themselves

    And just who do you think is going to pay the cost of shipping the parts from SparkFun to your local Radio Shack? (Hint, it's not going to be SparkFun or Radio Shack.) Shipping and handling is a minor component of the cost of an item purchased at retail because they're handled in bulk and the costs are amortized over a large number of items. Shipping and handling is a large component of mail order because the items are handled individually - and that doesn't change just because they're delivered to your local Radio Shack rather than to your doorstep. (And no, they're not going to absorb $5 S&H on a $0.75 part the way Best Buy will on a $20 cable.)
     

    I'll bet some of those hobby suppliers would have been amenable to merchandising a network of warehouses that they too could ship from around the US.

    Only if they're absolutely insane. Warehouses and inventory cost money, big money, and are only justified when the sufficient sales volume or demand for next day delivery justifies it. Neither exists in the case of retailers of electronic components - there's a reason why all the storefront chains of component retailers either gone bankrupt, been absorbed, or added additional lines of merchandise.
     

    My point being, once you already have a high-street retail presence and a logistics setup to handle distribution then they may have well found something to do with it.

    I grasped your point. Meanwhile you completely fail to grasp the cost and complexities involved. Same-day and next-day distribution adds both of these above and beyond the normal costs of retail logistics. There's a reason why few retailers have adopted that model, or limited it to stock on hand.

It's not a very tenable business model, there's a reason why every click-and-mortar retailer of which I'm aware limits same pickup to items in stock.

    Most of you probably don't remember back in the sixties when Radio Shack was the retail distribution arm of Allied Radio (yes, it was known as Allied Radio Shack), a major components distributor. It was a real parts store the. Eventually Tandy picked up the chain, began selling branded parts, and it was never quite the same.

    Um... most folks can't remember that, because it never happened. Tandy bought Radio Shack in 1972, and then Radio Shack bought Allied Radio in 1970 and merged them. (Prior to that, Allied Radio had been a subsidiary of Columbia and a competitor to Radio Shack.) They were only briefly known as Allied Radio Shack, before Allied was spun off by court order and it subsequently died. On top of that, Allied pretty much followed the same path as Radio Shack - it started as a parts and components dealer, but by the 1960's it had long since become a consumer electronics dealer with a strong sideline in parts and components.
     

    The reality is that the advent of the personal computer, the death of manufacturing in the U.S., and an educational system that no longer valued engineering skills combined to kill the electronics hobbyist market that the Radio Shack depended upon.

    The reality is, Radio Shack hadn't been wholly dependent on the electronics hobbyist market since the 1930's - when it entered the hi-fi market. In 1954, the Realistic brand was introduced as it began to move into the more general consumer electronics market. By the early/mid 1970's, though the product mix varied by store (especially if your local store was independently owned), the transition company wide was largely complete - viewed as a whole they had become a consumer electronics store with a modest sideline in hobbyist parts and components. The advent of the personal computer was a decade away.

    There are many causes to Radio Shack's decline and fall, but moving away from the electronics hobbyist market played no significant part.
