Graphing SSH dictionary attacks with HighCharts

After my 10-year-old basement Linux server died this week from a power outage, I took the sad step of giving up on it. It’s died before and I’ve patched it back together with a new power supply here or an addon PCI SATA card there, but I finally decided to throw in the towel since I had a newer old computer that had been idle for several years. The one that died was an Athlon K7 750 MHz with 512 MB ram. The new one is an Athlon 2 GHz (3200+) with 1 gig. For my uses, specs don’t really matter that much, but it’s nice to have more power for free.

Who pays the most tax? Who pays the least tax?

Why do I care? Maybe I don’t. But this is fun anyway.

Go to the IRS.gov website to the SOI Tax Stats page.

Download one of the Excel spreadsheets under Basic Tables: Returns Filed and Sources of Income. I used All Returns: Adjusted Gross Income, Exemptions, Deductions, and Tax Items for 2008.

Look at spreadsheet columns I through N. I & J show the amount of taxable income in each bracket and the number of returns in that bracket. M & N show the number of returns that had tax and the total amount of tax in each bracket.
