try "dscacheutil -h"

The dscacheutil does not seem to show anything. The -h option gives the help. When I try the -cachedump, I don't get any output.

To see the NS cache status you may run

sudo killall -INFO mDNSResponder

Thus the SIGINFO signal will dump a snapshot summary of the DNS internal state to

/var/log/system.log

Why is the Mac OS X version always way behind the latest Git version?

Is there a particular reason or is it that it's just not bothered being built that often that new versions of Git is released?

How can I build new versions of Git myself?

Screenshot Taking program in Python for Mac OS X.

I want to write my own Screenshot Taking program in Python for Mac OS X.

Example : Whenever Command + Shift + 3 is pressed ==> whatever is there on the screen, should be grabbed / captured, and should be stored on my local with my own desired path, and name should automatically given as SnapshotX.. as in Snapshot1, Snapshot2, etc...

The same goes with Command + Shift + 4 ==> the only difference is that, it allows you to select a particular area to be captured / grabbed.

Command + Shift + 5 ==> This one is a little bit tricky which I am looking for. This shortcut doesn't exist. I want to create one of my own, where it would grab the entire webpage's screenshot which I am currently working on, and store the name as the webpage's link.

How to clear DNS cache?

My system is set to go directly to the OpenDNS name servers for DNS resolution. However, the results I get from "nslookup" differ from what I get if I query the same name server from another machine with the same resolv.conf settings.

That leads me to believe that DNS info is being cached locally somewhere. I don't have bind or nscd installed.

Where is this caching taking place and how can I clear/flush it?
