One of the cancers they mention is pancreatic cancer.
A quick Google search suggests the prevalence of pancreatic cancer in the population is 13 per 100,000.
So if you gave this test with a 0.005 false positive rate and 0.5 true positive rate to 100,000 people it would miss diagnose 500 people and only correctly detect 7 cancers.
So given you had a positive test result there would be a 1-(7/500)=98.6% chance you did _not_ have pancreatic cancer.
1632[0] is the first in a series of entertaining alternate history novels, where an entire West Virginian town is transported to the middle of the Thirty Years war. It touches on some of these problems in having to translate modern knowledge to people in the past.
While it is true that S was originally a macro layer around FORTRAN code R has always been primarily written in C. Very little of R core is in FORTRAN, and essentially none of it is C++.
The language statistics show a good deal of FORTRAN (%24.5) [0], however that is largely skewed by the included LAPACK code [1], which accounts for 221,921 / 259,773 lines of FORTRAN in R.
While the order of the walls in Super Hexagon is random, each level has a predetermined set of walls. Once you identify which wall pattern is coming you know exactly the maneuver needed to traverse it.
This makes Super Hexagon more a game of quick pattern recognition than reaction time.
When I play it I am generally focused at the edges of the screen to quickly identify the next pattern and only using my peripheral vision to maneuver around the walls in the center.
Dvorak users in this thread should really give Colemak [1] a try. Dvorak has a number of issues [2] in modern usage and is also harder to learn; many more keys change from their QWERTY equivalents.
I have used QWERTY, Dvorak and Colemak for multiple years and Colemak is the clearly the best of the there for me.
Colemak changes relatively few keys from qwerty, especially compared to Dvorak. I use colemak full time and can still touch type qwerty reasonably fast.
I personally would recommend colemak [1] rather than Dvorak. While both are improvements over QWERTY colemak only moves 17 keys from their QWERTY positions, while Dvorak moves nearly all of them. In particular Ctrl-Z, Ctrl-C, Ctrl-V require two hands in Dvorak which is very inconvenient. In some applications these shortcuts can be rebound, but in many others they cannot. In colemak their positions (and all of the left-bottom row keys) are the same as QWERTY.
I used Dvorak for ~2 years and then switched to using colemak for the last 3+. OS support for both is widespread.
You can get back up close to your QWERTY speed in about a month or so (maybe less if going from QWERTY straight to colemak).
I switched to the alternatives to reduce RSI rather than speed and found it helped me with both.
This is IMHO the real benefit to zsh over bash. You can set zsh to share history between sessions and they are interleaved based on the time the commands were run. No more closing a session in the wrong order and losing half of your history for the day.
