Thank you your well thought article.

am rather very disappointed by the comments you receive. Too young. But who can blame them. I was young too.

Comment on A word on Haskell Monads and C++ by Jonathan Fischoff

You can clean up your using the Maybe monad, or with a MaybeT monad transformer.

You can get rid the case statements that way.

I have the same problem, and I tried “pasting” (forgive the term) your snippet AFTER the org-mode stuff (presented in the beginning of this blog) in my .emacs file. Got this error:
(eval-after-load “org-agenda”
‘(progn

Comment on A word on Haskell Monads and C++ by Giuseppe Maggiore

Monads are far, far more powerful than what you show here. You discuss printing (IO) and maybe, but the real power of monads come from using (and combining) the state, continuation, list and eventual monads. I really do not think your post scales beyond the simplistic examples of monads you have shown, but am curious to see it in action.

Also, use the do notation please: ignoring it is not healthy when discussing monads…

Comment on Life and times of a TCP packet by johnw

I just used the Python module Scapy to cause the packet to be transmitted. I never talked to the Ethernet card directly.

I created an Ethernet frame for my packet which directed the first packet from my computer to my DSL router. I then transmitted this packet using my Ethernet card.

-How is frame sent to Ethernet card? what function/technique is used by you?

Comment on Common Lisp on Mac OS X by Alberto De Lucca

Hi,

How can I revert this installation?

I only did these two steps:

sudo port install emacs +carbon sudo port install sbcl slime

but then installed Lispworks PE as per your suggestion.
I would like to uninstall emacs and sbcl for now.

How do I go about doing this?

Thanks!
