    That doesn't go very far in the microprocessor world. I worked for Cisco back in the early 00's and even back then tape out costs were approaching $1M for a 5 layer mask, today with sub-wavelength masks and chips using 12+ layers it must be tremendously expensive to spin a chip.

    So I wonder if the higher cost is just for the surgery itself? Because if so the average reduction of a day of inpatient care would easily make up the difference is surgery cost.

  4. Re:45 million? Tha's all? on Report: US Military Is Wasting Millions On Satellite Comms · · Score: 1

    Hehe, nice story. Btw I looked it up and the air force did decide to build a replacement for the P3, the new P8 is based on an ~$100M 737NG airframe but so far the cost per P8 is ~$1.1 billion, those were some damn cheap seats if they allowed us to kick that kind of cost down the road 30-40 years.

  5. Re:45 million? Tha's all? on Report: US Military Is Wasting Millions On Satellite Comms · · Score: 2

    It wasn't just a freaking seat, it was the entire bathroom, and they had to make large injection molding dies to create the new bathroom. The seat was just one of the parts that went into the new bathroom and the project cost was spread over x number of pieces of deliverable parts. Any time you deal with injection molding or just about any significant manufacturing process there are large upfront costs that lead to VERY expensive parts if you don't produce a lot of something (heck, even business cards get stupid expensive if you order less than a few boxes at once, which is why I have a few thousand business cards I'll never use as it's WAY cheaper to order me 10x more than I need then it is to even occasionally need an additional batch run). The alternative to the new bathrooms was scrapping the airframe and designing a new one, and if you haven't been paying attention lately to the way Air Force procurement is done that would have resulted in a LOT more cost than some $640 toilet seats. Btw thanks to those new bathrooms the P-3C Orion is one of a handful of aircraft to serve over 50 years bringing the cost per flight hour down quite a bit over building new replacements =)

    It made an operating profit, lifetime net profit of 500M on a cost of 128M obviously more than making up for any interest charges. If more units had been operated the program cost of 1300M could have been easily recouped assuming there were a half dozen more economical routes (likely).

    Yeah, it would be physically impossible for NYC to survive if it wasn't for skilled truck drivers bringing in loads of food every day via big rigs, there's not enough rail capacity to haul it all in and obviously no room to add more.

  11. Re:Big truck != Big company on NYC Asks Google Maps For Fewer Left Turns · · Score: 2

    Wait, you can buy a six figure truck, but $300 is too much to spend to have appropriate mapping?!? That's a complete BS excuse. Heck, I imagine one fine for having a truck on a route that doesn't allow them is enough to pay for the unit. Also I bet the fuel price search could save more in a month than the unit costs.

  12. One seems reasonable on NYC Asks Google Maps For Fewer Left Turns · · Score: 4, Interesting

    The request for right turn optimized routes seems reasonable, but the truck route seems stupid to me. If you're operating a large truck you should be using truck optimized commercial software, not freaking Google Maps. There are all sorts of things like bridge height, earlier lane alignment alerts (it takes a LOT longer to get an opening big enough for a big rig), hazmat restrictions, etc that the commercial packages take into account that google maps is unlikely to ever add so giving a truck route option seems like it would give drivers a false sense that google maps is an acceptable alternative to what they should really be using.

    You've mellowed but you think someone should forfeit 10 years of their life for essentially being an immature teenaged brat? That's roughly the amount of time you can expect to spend in prison for murder in Finland.

    Well, it IS attempted homicide to call in a high pressure situation where even Canadian police officers will be armed and filled with adrenalin. You have to remember that we have situations like Tamir Rice where a 12 year old boy was fatally shot because someone called in a report of someone with a gun in a park and the dispatcher failed to pass on the fact that the called believed it might be a toy.

    Well considering the numbers the GP post quoted were the DJIA composite I think pointing out that their P/E ratio is in line with historical norms despite being up 600% in 25 years is fine in assessing whether there is some huge bubble in that number.

    If you want to look at the broader market the NYSE composite index has a P/E of 21.1 which is a bit over the 18-20 range that most risk averse investors would be looking for, potentially pointing to the need for a correction, but again hardly pointing to some huge speculative bubble that is going to wreck the economy.

    Ok,
    US:
    133,312km of coastline 319M people for for 418km per million inhabitants

    UK:
    19,717km of coastline for 64M people for 308km per million inhabitants

    consumption
    US 13,394 kwhr per capita
    UK 5,700 kwhr per capita

    So on a coastline per capita per kwhr the UK is ahead by a fair bit, but mostly because the US consumption is 235% higher. Ultimately though we have to bring our consumption in line with resources available so the coastline per capita number is the more interesting one to me.
