Preserving order with LINQ
...for linq to objects that doesn't preserve order and is more efficient that one that does preserve order.

printf("%.6g", 359.01); // 359.01

printf("%.6g", 3.01357);...
Gets byte array from a ByteBuffer in java
... Java doesn't have the notion of unsigned integers, only signed ones. If you want "unsigned bytes", you need to cast as int and use a bitmask: int unsigned_byte = b[k] & 0xff; for some value of k.
