New email spam using Yahoo groups

Just saw a new format of spam that is hitting our servers.
Instead of the email containing the contents of the actual spam text or image, or a link to their own spam site, spammers are now putting in just a link to a yahoo group message screen like:  http://groups.yahoo.com/group/<some_random_words>/message
This is the spammer’s attempt to bypass spam filters but the question is how effective is this spam?  Its more of an annoyance for mail readers as they can just delete the email without even going to the site to check what the spam content might be.    Of course, there are those who just keeps on clicking links without thinking.
I wonder if a particular page can be blocked so these users won’t be able to visit those sites.  We can’t block yahoo groups outright.

Nokia N900 woes: Cannot answer the phone immediately

Sometimes I don’t know what the unit seems to be doing.  This is because sometimes, I’m not using it and a phone call comes in and I can’t open it  to answer the call.   The screen just remains blank and I have to wait a while longer before the screen turns on.  Even sliding the switch doesn’t help.  Some times it takes so long that the caller has already hanged up and I have to return the call instead.  Its ok if the caller is using a Globe which I’m using an unlimited plan, but if its a call from a Smart line, then I have to pay extra on my monthyly bill.
I don’t know if this has to do with its multi-tasking ability such that there are a number of processes running in the background, specially softwares which are supposed to be still in Testing or Development?  That was the warning given when install softwares from these repositories.  But then again, if I did not start the program, then they shouldn’t have been running in the background.   I guess I have to check each of the programs and kill those runaway processes and see if the load will go down.

SSH on the Nokia N900

When visiting clients to check on their systems or problems, I usually bring along my laptop so i can hook into their network and troubleshoot.  Now, I can do without bringing it.
With the Nokia N900, I am able to connect to the client’s network via wifi and test their networks.  Also with its X-terminal and SSH, I am able to login to the linux server and remotely check on errors in the logs to track down the problem.
This is very convenient as I don’t have to lug around a bag with the laptop.
Next step is to find out if I can use the N900 as a bootable drive and boot off it  into a computer.  Right now, I do this using a USB pendrive.

My Notes on Tumblr

Tumbler, Facebook, WordPress, Mambo/Joomla… Still undecided which to settle into.  My original posts were in the Mambo/joomla CMS so moving away means loosing my old posts.
This is the reason why when I was testing out wordpress with my own install, I used http://www1.purity.ph.   Now with Tumblr, which I found I can change to the domain that I have, I customized the domain on my Tumblr account to http://notes.purity.ph

Update June 26, 2013
I've decided to delete the Wordpress site and consolidate the contents here.  Moving each article so some of the contents may no longer apply.
