The Linux Alternative

Adapting Linux as the main OS for personal computing does come with some issues since there is a lot of software out there that is simply not available for Linux systems. One would then have to rely on Windows/Mac for short periods of time, or try to run Windows applications in Linux using Wine or Codeweaver Crossover Linux , Cygwin or seek virtualization solutions using software like VMware. Before resorting to the solutions proposed above, one should consider a Linux analog of the Windows application one would like to use. A neat resource for that purpose is this website.

I came across this site while trying to find a free Linux alternative to the Origin package for plotting and graphics. Time to give Scigraphica a try!

UPDATE: Here is an interesting list of 50 annoying proprietary programs and their open-source alternatives.

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...

An Exercise in Obstinacy, Deception, and Self-Destruction

There is no other way to describe the policies of the current leadership in Eritrea. Please watch this appalling interview of the Eritrean President Isaias Afewerki with Riz Khan of Aljazeera and come up with your own series of adjectives to describe that incredible exchange. The fact that Eritreans are dying under the oppressive and misguided dictatorship of Isaias Afeworki frightens and saddens me very much. The fact that there is no immediate hope is downright depressing.

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.
