  • Geoff's site: Expensive Computers are Worth the Price
    worse 1500 is too much money for a computer That is the wrong way to think about it Here s why According to RescueTime I average 10 hours a day on my laptop Assuming I upgrade every 18 months that s 5 400 hours of use Amortized over its life a 1 500 laptop costs me 28 cents per hour A 500 laptop would be 9 cents per hour The important factor I haven t mentioned yet is the amount of value I can create per hour Let s be extremely pessimistic and say I create 5 worth of value per hour on average Let s also say the 1500 laptop makes me 10 more efficient than the 500 laptop That means I would create 5 50 worth of value each hour on the expensive laptop Subtracting the amortized cost of the expensive laptop still leaves me with an extra 31 cents per hour The expensive laptop costs 3x as much and only improves my performance by 10 but it still comes out ahead purely for economic reasons This is because the amount of value you extract or create using a computer is much greater than the hourly cost of

  • Geoff's site: On Alpha Geeks and Gadgets
    such tightly integrated devices Instead they buy whatever best satisfies their needs Lately those products have been Macs and iPhones So are alpha geeks done with hardware tinkering I doubt it I think a new type of device will show up the wearable Recent advances in microdisplays and embedded computing have made wearable computers a borderline practical idea And individuals can build them for about the cost of a laptop A few people have already hacked their own together from video goggles like the Myvu Crystal and single board computers like the BeagleBoard An often heard objection to wearables is I already carry a computer with me It s called an iPhone and I can use it any time That s true but most people don t realize how much trivial inconveniences can affect their behavior Every time you want to look something up you have to pull the phone out of your pocket and unlock it You lose eye contact with anyone you were conversing with It takes time for the phone to come out of hibernation and run whatever app you want to use The screen is visible to those nearby so you can t message a friend What s the name of this person next to me or search your e mail archives for a forgotten message that has come up in discussion Two major issues with wearables are fashion and software Fashion will probably be resolved as technology gets better and people become more used to seeing wearables Software is going to be a bigger problem Wearables have to be extremely responsive The idea is to completely integrate the computer with your life Smartphone software has a similar constraints but not to the same degree A wearable with good software would be outrageously useful Imagine having

  • Geoff's site: Time Management
    re paid for you have to run errands and do chores shop for groceries go to the bank yard work vacuum cook wash dishes etc Let s say you average 90 minutes a day on that which is 548 hours per year 3 292 hours remaining How long is your commute The average is 25 minutes each way so just over 208 hours a year 3 084 hours left How long do you take to get ready in the morning 40 minutes 240 hours 2 844 left Do you exercise Maybe you don t work out every day 1 hour a day 3 times a week 156 hours 2 688 left Now let s say you re 25 years old and healthy According to most actuarial tables that gives you even odds of sticking around for another 50 years 2 688 hours 50 134 400 hours That s 15 years I admit it s a very rough estimate I left out a lot of factors such as anything related to raising children People work less when they re older but that s partially offset by more time spent being sick I d also weight calculations toward free time in younger

  • Geoff's site: Stanislav Petrov Day
    the world When an early warning system reported the Americans had launched ICBMs Petrov told his superiors it was a malfunction Had he decided incorrectly the Soviets would have launched their nukes causing the United States to actually launch their nukes Billions would have died I am continually amazed by how few know about this incident The average person could probably tell you the latest celebrity gossip or which team

    graham cracker The heat of the peppers and the cold of the ice cream complemented each other or something I m no culinary expert The art was pretty impressive too I ve thrown a few photos up on Flickr and a few more in my gallery My favorite piece was a 40 foot tall metal statue of a woman Not only is the statue visually appealing it s an impressive

  • Geoff's site: Return of the Supermotard
    t be available until tomorrow morning Now that I will not abide I took a breath The words I wanted to say would not help me get my bike back Had I said them the end result would have been to annoy a sleepy lady and force me to come back to the impound lot in the morning I thought up some new words that would help me get my bike back I exaggerated my plight Lady I have a flight in the morning and I won t be back for a week That bike is my only vehicle You re the only person who can help me right now This was somewhat true I had a flight but it was in the afternoon I own a car but I haven t driven it in weeks Really I just wanted my bike The sleepy lady relented My bike would be at the impound lot in an hour Where was it coming from Why couldn t I take a cab to where it was now Again I bit my tongue Finally done with bureaucratic bullshit I had spent a good chunk of my Sunday to get to this moment Carrying my helmet everywhere I went Fiddling with the key in my jacket pocket Imagining the engine sound the smell of fuel rich exhaust the exhilaration of twisting the throttle dropping the clutch and accelerating quicker than my mind could comprehend Buoyed by these images I strode through the impound lot Smiling Anticipating Key in hand ready to ride a celebratory wheelie all the way home Except wait a second Where s the keyhole in the ignition The thief made a few modifications to my bike Keyless ignition The thief removed the ignition There s no place to insert my key Now

  • Geoff's site: Insert Frozen Food Joke Here
    examining evidence So bring on the evidence This presentation by Brian Wowk does a good job showing the state of cryopreservation technology embed For those who don t want to spend 25 minutes watching the video the main points are The common conception of freezing damage is backwards Ice doesn t cause cells to expand and burst Ice crystals form between cells dehydrating and squishing cells as the crystals grow Cryoprotectants can limit or even eliminate ice formation at liquid nitrogen temperatures Instead of freezing the solution increases in viscosity as temperature drops Around 120ºC the solution reaches its glass transition temperature and becomes an amorphous solid Cryoprotectant research is ongoing A decade ago cryoprotectants needed cooling warming rates of 70ºC per second to prevent ice formation Cell survival rates were around 50 in tissue samples Today s cryoprotectants can revive 90 of cells with cooling warming rates of less than 1ºC per second Wowk s team used their current best cryoprotectant M22 to successfully cryopreserve thaw and transplant rabbit kidneys Based on evidence from victims of hypothermia barbituate overdose and cardiac arrest silencing electrical activity in the brain doesn t erase any long term memories Cryopreserving the brain should preserve all aspects of self SEM micrographs of cryopreserved brain tissue show fine structure is preserved Individual axons are unharmed Even synaptic vesicles are preserved Cooling cryoprotectant solution too far below the glass transition temperature will cause fracturing from thermal stresses While they make revival harder the fractures are few in number and typically cause simple translations of tissue The information destroyed is negligible Despite limited funding cryopreservation techniques have improved substantially Cryopreservation and transplantation of large organs is expected in 10 years Alcor uses M22 to cryopreserve the brains of their customers The Cryonics Institute uses a similar solution
