... if you don't have accuracy info then you can't use a Kalman filter. It's completely fundamental to what the Kalman filter is trying to do.

What is the rationale for all comparisons returning false for IEEE754 NaN values?
Why do comparisons of NaN values behave differently from all other values?
That is, all comparisons with the operators ==, =, where one or both values is NaN returns false, contrary to the behaviour of all other values.

Why is there no Constant feature in Java?
...hods and pointer to const type. The enhancement request ticket in the Java Community Process for implementing const correctness in Java was closed in 2005, implying that const correctness will probably never find its way into the official Java specification.

Why do C++ libraries and frameworks never use smart pointers?
...rs to your heart’s content. Their source is available to your library at compile time, so you rely on the stability of their interfaces alone, not of their implementations.
But because of the lack of standard ABI, you generally cannot pass these objects safely across module boundaries. A GCC shar...

#!/bin/bash
SOURCE="${BASH_SOURCE[0]}"

Effects of the extern keyword on C functions
...ction from bar.c when it's linked.
By using 'extern', you are telling the compiler that whatever follows it will be found (non-static) at link time; don't reserve anything for it in the current pass since it will be encountered later. Functions and variables are treated equally in this regard.

What is the reason for performing a double fork when creating a daemon?
...a session leader. That is done by setsid(). So, the first forked process becomes a session leader after calling setsid() and then we fork again so that the final, double-forked process is no longer a session leader. Other than the requirement of setsid() to be a session leader, you are spot on.
