Hit Parade – find out who’s DoSing your site

This script goes over web server log files and sorts IP numbers by number of hits.¹

Once you know which IP numbers are causing trouble, you can ask your system administrator to block them. In some cases you might even have a way to block specific IP numbers from a web-based control panel.

Another (less efficient, but sometimes practical) way is to block those IP numbers in your .htaccess file like this:

order allow,deny

deny from 123.45.6.7

/* Simplest Simon - a game for a bare naked Arduino
 
 Recently I've got my first Arduino ever, and I'm still waiting for my order of
 breadboard, jumpers, resistors, etc. (where I live, such things aren't common).
 This led (pun intended) to the question "What shall we do with a bare Arduino",
 and the unavoidable answer: "Something with the pin 13 on-board LED".
 
 So there you have it. A Simon-like game where the Arduino flashes 8 bits on the LED
 (steady meand 1, blinking means 0), and then you have to send a sequence of 0/1s

Fairly Simple Simon – an Arduino memory game for 4 LEDs and 4 switches

The FSS is a simple board with 4 leds and 4 normally-closed switches
(each led goes via a 150Ohm resistor, and each switch has a 10KOhm
pull-resistor connecting between the output and ground).

See breadoard (made with fritzing):

In real life it ain’t that pretty :)

/* Simple Car game for a 16x2 LCD display 
   You can use any Hitachi HD44780 compatible LCD.
   Wiring explained at http://www.arduino.cc/en/Tutorial/LiquidCrystal
   (I used theLCD Electronic Brick on bus 1:
     rs on pin 2, rw on pin 3, enable on pin 4,
     data on pins 5,6,7,8)
   There's also a "steering wheel" potentiometer on analog input 1,
   and a Piezo speaker on pin 9 (PWM).
   
   Enjoy,

A simple trick against CSRF for web.py (webpy.org)
* At the GET() template, you add a hidden field called csrf_token with value "$csrf_token()"
* The POST() should have the @csrf_protected decorator
That's it.

Request for comments:
* Is this secure? Can you see any holes?
* Is there anything in [or for] web.py that does this? Am I reinvevting the wheel here?
