If we look at jet aircraft, wear depends on the airframe and the engines, and the airframe seems to be the number of pressurize/depressurize cycles as well as the running hours. Engines get swapped out routinely but when the airframe has enough stress it's time to retire the aircraft lest it suffer catastrophic failure. Rockets are different in scale (much greater stresses) but we can expect the failure points due to age to be those two, with the addition of one main rocket-specific failure point: cryogenic tanks.
How long each will be reliable can be established using ground-based environmental testing. Nobody has the numbers for Falcon 9R yet.
Weight vs. reusable life will become a design decision in rocket design.
hopefully this takes on and forces advertisers and publishers to switch to cpa instead of the meaningless cpm/cpc models of the past. Then hopefully we'll all see fewer, more relevant, more expensive ads for stuff we actually want to buy.
i use adblock (not plus) on chrome, but i also use dnsmasq/dhcp and some scheduled scripts on my home router running tomato usb to block almost all ads on all devices.
i don't get ads, so i don't get ads.
wait, Windows locks up randomly now?
wait, you weren't living at home with your parents when you were 16?
If that egg were male it would have still eventually been able to mate with its mother. Thus, mother and child were not different species. Evolution is not a single-generation event. It's a gradual change over many generations. Speciation almost never occurs in individuals.
Like others I found the headline confusing. I read it as "Researchers are predicting the use of Wikipedia as a vector for the spread of disease". This may mean that:
- Disinformation and ignorance are diseases.
- Memes and computer viruses are diseases.
- Wilipedia contains information that leads to depression.
- Instructions on Wikipedia lead to substance abuse.
- This is getting entertaining, fill in your own reason here.
paint.net doesn't entirely suck.
One of the definitions I found was:
One who makes great sacrifices or suffers much in order to further a belief, cause, or principle.
I am sure that fits. While SpaceShip II is mainly intended for a non-exploration purpose, the program has resulted in some significant advances in rocketry and White Knight II has significant non-tourism use. These pilots have been involved in other space efforts, I remember the one who was injured from the Rotary Rocket test flights. There are lots of safer ways for these folks to make as much money as a test pilot is paid. They do what they do to advance our progress in aeronautics and space.
Martyrs? Who killed them for their beliefs?
Go away, troll. They certainly died while pursuing something intensely important that they were willing to risk their lives for. The fact that you weren't around to pull the trigger makes them no less martyrs.
consumer devices that do not have the USB logo can use whatever VID/PIDs they like. there's no law governing this except the trademark of USB's logo.
the routine inside thier drivers as assertained from the symbol tables in the driver code was called "BrickClonedDevices"
do you have a link for that? curious.
or a leak?
