anonymous emailing for mailing lists that expose email addresses

How do I send a message to the mailing list without exposing my email address to 
spambots?

cheers,

Design Patterns: common "Template" solutions to regularly encountered problems/variations-on-that problem. Be careful when learning these that you don't fall victim to "when you have a hammer, everything is a nail". Also learn the Anti-patterns, wikipedia has a good list of anti-patterns.

Algorithms & Data Structures: Analysis, average running time Big O is most important, but understanding worst-case runtime is important too. Designing algorithms vs knowing when to leverage an existing one.

the C++ standard library provides a great many of these, it has a high efficiency sort (from ), it has good collection data structures (vectors, linked lists, maps, etc)

Objected Oriented Analysis And Design: Knowing when to make something an object, when and how to use inheritance and polymorphism, when to not make something an object. Plain old data objects. separation of responsibility: UI is not logic, logic is not UI.

Threading: proper thread synchronization techniques (mutexs, semaphores, conditions, etc), threading patterns such as Producer-Consumer, Inter-process communication

Automata & Computability: (Deterministic|Nondeterministic) Finite State Machines, Regular Languages, Turing Machines

Programming Languages: LL language parsing & rules authoring.

Computer Architecture: Processor design, pipelining, caching, function calling conventions, etc - how to use this knowledge to write more efficient programs

KDE okular html links -> firefox

Use firefox instead of konqueror for html links in pdfs viewed in okular:

Type in html in the search field and move firefox above konqueror for all html like content.

Have a lot of fun!

MySQL server on Ubuntu or debian

To setup a mysql server on my ubuntu 9.10 box, I followed this guide:

http://library.linode.com/databases/mysql/ubuntu-9.10-karmic

But connecting from another host gave me the following error:

$ mysql -u mysqluser -p --host=myhost.com

ERROR 2003 (HY000): Can't connect to MySQL server on 'myhost.com' (111)

http://dev.mysql.com/doc/refman/5.1/en/access-denied.html

The above link indicates this is a network error.

http://www.aboutdebian.com/database.htm

Referring to the above link, I found to enable access I needed to edit /etc/mysql/my.cnf, specifically, change the bind-address from 127.0.0.1:

#bind-address = 127.0.0.1
bind-address = myhost.com

and restart mysqld:

$ /etc/init.d/mysql restart
