Save Some Bandwidth - Block Ads

My previous post on saving paper and ink/toner using the Aardvark Add-on on Firefox has inspired me to seek other topics on efficiency. This post advocates the client-side blocking of ads on the web as a way of being less wasteful with internet bandwidth. I feel slightly guilty about this because a lot of the free content on the internet is supported by ad revenues, and users blocking those ads might deny access to those revenues for the providers of the free content. However, if you are like me and you almost never pay attention to or click on any ads, then you are probably doing no damage.

How do I know what to block? I looked through my Firefox cookies and did a search for 'ad'. I would then selectively block those domains. You can block the ad servers locally on your computer, for example suing 'iptables' in Linux or Network Magic in Windows, or for your whole network through whatever interface you have. In my case, the easiest thing was to configure my wireless router to block the ad servers.

  1. Find out what to block:: If using Firefox, click on Edit>Preferences to open the preferences window. Select the 'Privacy' tab and click on the 'Show Cookies' button. Then, search for keyword 'ad' in the list of cookies, or manually locate cookies that could be from an ad server.
  2. Block the ad servers:: I chose to block them using a website filtering option on my wireless router. Most routers should have an easy interface that easily allows website filtering/blocking.
Well, in the simplest possible way, I have probably cut down my internet bandwidth usage by 10%??! A few of the sites I frequent look substantially leaner already.

Distribution of Wealth in the US

The rich get richer and the poor get poorer. I heard this statement quite a bit lately particularly in light of the sub-prime mortgage and general housing crisis in the US. The country has enjoyed significant economic prosperity and both Clinton and Bush boasted economic growth under their reign. Unfortunately, the beneficiaries of the economic boom are not people from all economic backgrounds, but rather the top 10%. To make things worse, Bush gave tax cuts mainly targeting the top 10%. Being more of a numbers guy, I always wanted showing the validity of the-rich-get-richer-n-the-poor-get-poorer statement. Thanks to Wikipedia , I have finally found it!! Both the mean and median net worth of families for the bottom 50% of the population has remained absolutely flat while the 75th-90th percentile see a decent growth and the top 10% enjoy the most appreciation on their net worth. So, if you factor in inflation, the-rich-get-richer-n-the-poor-get-poorer probably holds true. The g...

IPtables, SVN, and NMAP

I reviewed some material on IPtables, SVN, and NMAP just for the sake of keeping my mind busy. Here are some useful notes: IPtables - best resource found at HERE SVN - best, as in the quickest and simplest intro could be found HERE NMAP - I honestly don't see in using it for more than port-scanning in a few instances. Anyway, here are a few other options that might come in handy at some point. nmap -sT/sS/ sX/sF/...[-P0] IPADDRESS(range) == to check which ports are open nmap -sP IPADDRESS(range) == a simple ping scan for availability nmap -sO IPADDRESS(range) == check what IP protocols are available nmap -sV IPADDRESS(range) == a scan with version detection Other useful flags: -O == detects OS, part of -v (verbosity) flag as well -A == detects OS and versions -v == request high verbosity/detail -F == performs a fast scan of only a few common ports Installing Perl modules Perl modules may be installed using the CPAN module or from source.

Reasons to Vote for Barack Obama

Not that I am eligible to vote or anything ... but if I could, I would vote for Barack Obama for the following reasons. He listens to experts . He has assembled a group of smart and practical intellectuals to advise him on all sorts of topics. Hillary has her own agenda and ambition which appears to keep her from entertaining any "elitist" agenda. He is a good manager. The way he hired very intelligent people to run a nearly flawless campaign to beat an established and seemingly unbeatable opponent in Hillary Clinton is commendable. He really knows how to surround himself with a smart group of people who can get things done and that is exactly what this country needs. Hillary hired people on the basis of their loyalty and counted on friends of the Clintons to win her the nomination. Unfortunately, all that influence and political capital could not overcome the grassroots movement Obama initiated. He is not an ideologue . That allows him to make good decisions for this...
