+# ----------------------------------------------------------------------
+
+# (1) Try to re-enable the cross-site scripting (XSS) filter built
+#     into most web browsers.
+#
+#     The filter is usually enabled by default, but in some cases it
+#     may be disabled by the user. However, in Internet Explorer for
+#     example, it can be re-enabled just by sending the
+#     `X-XSS-Protection` header with the value of `1`.
+#
+# (2) Prevent web browsers from rendering the web page if a potential
+#     reflected (a.k.a non-persistent) XSS attack is detected by the
+#     filter.
+#
+#     By default, if the filter is enabled and browsers detect a
+#     reflected XSS attack, they will attempt to block the attack
+#     by making the smallest possible modifications to the returned
+#     web page.
+#
+#     Unfortunately, in some browsers (e.g.: Internet Explorer),
+#     this default behavior may allow the XSS filter to be exploited,
+#     thereby, it's better to inform browsers to prevent the rendering
+#     of the page altogether, instead of attempting to modify it.
+#
+#     http://hackademix.net/2009/11/21/ies-xss-filter-creates-xss-vulnerabilities
+#
+# (!) Do not rely on the XSS filter to prevent XSS attacks! Ensure that
+#     you are taking all possible measures to prevent XSS attacks, the
+#     most obvious being: validating and sanitizing your website's inputs.

+// []     1. Battery Level display in Volts - e.g. 14.5V
+// []     2. Gear Position Indicator on LCD - e.g. 1, 2, 3, 4, 5, 6, N
+// []     3. Ambient Temperature in Farenheight or Celsius - e.g. 62.5F
+// []     4. [Future] LED display of gear position (one led for each gear 1-6, in different colors, N will be blinking on 1)
+// []     5. [Future] Accurate display of the fuel level (in percentage)
+// []     6. [Future] Show Fuel consumption - MPG or KM/L, TBD: need to tap into motorcycle's speed sensor (PWM)
+// []     7. [Future] Fix the OEM V-Strom Fuel Gauge to become linear
