comment How to force split tunnel routing on Mac to a Cisco VPN
For those not familiar with LaunchDaemons, I wrote a guide in my answer here describing how to call a script to run every time you connect to VPN. (By the way, +1 excellent answer, but I needed a little more to get the gist working).

comment How to selectively route network traffic through VPN on Mac OS X Leopard?
The first solution will only work on a PPP VPN. The following solution will work on a Cisco VPN (and other types nothing specific to Cisco) superuser.com/questions/91191/…

comment Why do some downloading files not know their own size?
@Alfo - You have a valid point, dynamic files could be entirely created first in memory and then sent via HTTP and its easy to calculate content length. However, if the server is sending many large dynamically created files that will be broken up into many packets, it makes sense for the server to just start sending the chunks as they are calculated (versus to having to create every large file in memory and then send it). HTTP 1.1 specifically designed the chunked transfer encoding for this purpose.

comment Why have CPU manufacturers stopped increasing the clock speeds of their processors?
-1 The fourth power part is not right. Power (heat generated per second) in CPUs is (roughly) linearly proportional to clock frequency like P ~ f C V^2 + P0 (en.wikipedia.org/wiki/CPU_power_dissipation). Granted voltage depends on clock speed (though not necessarily linear). See: physics.stackexchange.com/questions/34766 Bottomline, power generated by CPU is roughly linear to quadratic on clockspeed in the range of 1.6 GHz - 5 GHz. (Not prop to f^4 ).

comment Linux command to find files changed in last n seconds.
In linux, using find (from GNU findutils 4.4.2), I get an error with this command: find: missing argument to `-mtime'. However, I can get the desired behavior using -mmin and a decimal argument. I could not find any reference in the manpage for find for using s as an argument.

comment Should I defrag an SSD drive?
@PatrickM - Agree. It worth pointing out that SSD seek time can almost always be ignored unlike with an HDD where seek/rotation time is the dominating factor (and reading sequentially is almost "for free"). With a typical queue depth (QD=32) for an IO-intensive application reading 4K blocks randomly takes roughly double the time of a sequential read on SSD. On an HDD, seek time is ~10ms (and read 1 MB sequentially is ~20ms) but a 1 MB read randomly in 4K blocks would take ~2560 ms (100+ times slower reading randomly than sequentially).
