os-x

If you are a developer (just a nerd will do, too), you have definitely put a fake DNS entry or two in your /etc/hosts file, at one time or another. Few things are more frustrating than doing that and having to restart your computer for the change to pick up. If you are running a local dns server (e.g. BIND) a glitch like that can happen all the time.

No worries, though. The little command below, ran from the Terminal, will clear dns cache and let your changes be applied instantaneously:

> lookupd -flushcache

or on Mac OS-X 10.5.x (Leopard):

> dscacheutil -flushcache

P.S. I don't know how to do the same on Windows, but the same problem occurs on that platform as well, since it also uses local DNS cache. If you know a solution, feel free to leave a comment :).

The much awaited first software update of iPhone is out!

One of many novel things about iPhone, setting it aside from the CellPhones 1.0, is that it is supposed to be frequently and significantly improved through a series of software updates. This first update is not that exciting - just a collection of bug-fixes, but marks a point in the history. I installed the update - the phone still works, so - good news :)

I wonder if the update will shut down some of the breaches the community was able to make into the closed world of iPhone.
