it's ugly when you big functions doing math with names like min_temperature, max_temperature, ambient_temperature
markrages
Apr 12, 2014 06:41
but "temperature" is too long to type all over this function
markrages
Apr 12, 2014 06:41
ltemperature = read_sensor()
markrages
Apr 12, 2014 06:41
heh, that's the confusion I want to avoid
markrages
Apr 12, 2014 06:35
"temp" is no good, nor "tmp"
markrages
Apr 12, 2014 06:35
what is a short name for a variable holding temperature?
markrages

LRU means least-recently-used. You could use it for maintaining a cache, for example.

Q: In LRU square algorithm, is the least-recently-used row always zero?

markragesMy copy of Hacker's Delight is at home, and the web resources I've found aren't clear on this detail. I have written the following 8-level LRU, using the well-known "row-column square" algorithm. (Is there a better name?). #include <stdint.h> typedef union { uint8_t rows[8]; uint64_t c...

c algorithm lru

I asked this in mothership stackexchange, any one here have an idea?

there's a company that makes a heart rate strap that guesses your power output based on heart rate... so you could use that all day.
markrages

a little of that, but mostly sensor design.

what's that?

I think it was different folks writing the SDK.
markrages
Apr 27, 2013 04:37
the hardware design in this chip is excellent and a pleasure to work with
markrages

Maybe this is an example of why mandatory comments are a bad idea
markrages
Apr 27, 2013 04:36
but if you are just rephrasing the variable names, you aren't adding value
markrages
Apr 27, 2013 04:35
I actually like that style of commenting
markrages
Apr 27, 2013 04:34
because they just restate what the code says, without any "why"
markrages
Apr 27, 2013 04:34
yes, well that would explain why the doxygen docs are worthless in this case
markrages
Apr 27, 2013 04:32
which would support that theory
markrages
Apr 27, 2013 04:32
the whole SDK is full of that kind of comments
markrages
Apr 27, 2013 04:31
redundant comments, why?
markrages
Apr 27, 2013 04:25
can anyone explain the code that mystified me?

I analogize other things to circuits, to help me understand.
markrages
Mar 9, 2013 03:45
yep, it's been a long time.

you don't need to be thinking about energy of a positive test charge
markrages
Mar 9, 2013 03:24
I think physics makes it harder to understand, since it derives things from first principles
markrages
Mar 9, 2013 03:24
well, potential energy is potential energy
markrages
Mar 9, 2013 03:23
right

circuit theory can be used to explain the behavior of any linear system. but I can't think of one my wife would be familiar with.
markrages
Mar 9, 2013 03:22
I'll think about it

ping pong balls are a good idea
