Tips and Tricks

Since there ain't a whole lot happening in my life, I might as well use this venue to make a list of cool Linux tips and tricks.

1) Hey, I need to start spending less time reading Lakers rumors. Why not start by blocking access to the Lakers forum I frequent most, namely forums.lakersground.net (64.38.208.184). Here is how it's done using iptables.

iptables -I INPUT -s 64.38.208.184 -d 0/0 -j REJECT

2) If you would like to view your iptables filters/instructions, you can just type

iptables -L

3) To check which ports are open, one can use nmap as

nmap -sT localhost OR
nmap -A -sT localhost OR
nmap -sT IPaddress

4) To convert OGG to MP3, use ~/bin/ogg2mp3.pl

Correlation Between Taxes and Social/Economic Programs

I have always wondered if the taxes people pay correlate with the availability of social and economic programs and safety nets, not to mention the military programs that protect them. This idea comes in light of the notion that Europeans are highly taxed compared to their American counterparts, but they seem to have access to free (or almost free) education and health care while the US provides neither. The Europeans live and work at a more leisurely pace than Americans and they have the comfort of knowing that their government has put safety nets in case a disaster. The Europeans do a lot to ensure that all their citizens have comparable opportunities, and thus you are less likely to see a huge gap between the poor and the rich. Perhaps the lack of incentive to excel has stifled entrepreneurship and innovation in Europe to some extent. In fact, Europe has historically high unemployment rates than the US and the size of government there is significantly larger than that of the US....

Obama, McCain and Campaign Financing

Obama and McCain had at one point both agreed to take public financing in September 2007 if they were their respective party's nominee. At the time, they were both long shots to get their party's nomination, but oddly enough they have both made it to the general election. As for their promise to take public financing, McCain decided to keep his promise while Obama opted to finance his campaign through his own fundraising. In doing so, he became the first ever presidential candidate to forego public financing during the general election. In February 2008, McCain started criticizing Obama for not keeping his promise to take public financing. How legitimate are McCain's accusations? That's what I wanted to discuss. According to The New York Times campaign finance page , Obama and McCain raised $401m and ~$150m, respectively, prior to earning their party's nomination. The public financing package is $84m over two months (Sept-Nov). For McCain, whose averaged $7....

Plea to Barack on Foreign Aid

Barack Obama has been my candidate of choice from the beginning. I have outlined a few of the reasons I support him . One I didn't mention is the issue of foreign aid. As I discussed earlier, US government's foreign aid as a % of its GDP is one of the lowest for any developed nation. Economic Aid to Developing Countries - The Stats To make it worse, much of the aid is given to two sources: Military and economic aid to Israel and Egypt to keep some peace in the Middle East Colombia, Peru and Bolivia to fight drug The tiny bit that is left goes to countries where the US has foreign policy interests. The aid is used for political leverage. Here is where Barack Obama comes into the picture. He has said that diplomacy and restoration of American image in the world would be the pillars of his foreign policy. One way to improve America's image in the world is to provide more foreign aid, particularly one that is not directly used for political leveraging. Obama promised ...
