Bill Gates visited UW

Too bad I wasn’t there. But thanks Mr. Gates to stop by the only Canadian university in his tour. I’d love to be there. Hope my Alma Matter will continue to be on the leading edge of technology. The quantum institution I think is going big.

root@r1 [/var/log]# man sudo
sudo allows a permitted user to execute a command as the 
superuser or another user, as specified in the sudoers file....

Useful Linux command – last

[root@s1 ~]# man last
Last searches back through the file /var/log/wtmp (or the 
file designated by the -f flag) and displays a list of all 
users logged in (and out) since that file was created.

[root@s1 ~]# last -R

Payment Processing Job – Scam

Beware of these. Nobody trust stranger to send money too, unless it’s free money for them too.

New Browser War

Now it’s what advanced features can be delivered. Not many of backward compatibility issues. Good for developers to take advantage of more interactive functionalities.

Setting up a CentOS worker

Quite easy, everything can be done w/ yum
– Enable CentosPlus for PHP5
– yum install php
– yum install mysql
– yum install php-mysql
– yum install php-gd
– Enable mysqld/httpd on chkconfig

Ideas for Google

BACKGROUND: Google is the prime example of a late best mover. Do what your competitors already do and do it better. Their mission is to organize the world’s information so that it’ll be useful and universally accessible. Their organization’s culture is open to experiment new ideas/projects.

IDEA #1: Google Auctions
To keep up their mission, the propose is to offer auctions through Google/Froggle. Either (1) entering a partnership with eBay, Yahoo! Auctions, uBid (major online marketplaces) to integrate current auctions with search results (with details and not simply an affiliate link to eBay site) or even more ambitious, (2) providing auction services like eBay. Problem with (2): what improvements can be done to eBay, a pretty good system in my opinion? The idea may have been investigated by Google but we, the public, have not seen it. This business plan will be proposed to Google’s as new project to the expanding portfolio.

IDEA #2: Google Portal (scrapped, they already have it http://www.google.com/ig, but could be improved)

IDEA #3: Google Dating – Search for people or dating, maybe something like the social network, orkut.com, not that new.

Google Sitemap Generator

xml-sitemaps.com is a good one. Idea for service: signup for sitemap, add a site, then give FTP login, routinely (daily, weekly) update the sitemap and upload to their server (need trust).
