Storing time-series data, relational or non?
... creating a system which polls devices for data on varying metrics such as CPU utilisation, disk utilisation, temperature etc. at (probably) 5 minute intervals using SNMP. The ultimate goal is to provide visualisations to a user of the system in the form of time-series graphs.

How do the likely/unlikely macros in the Linux kernel work and what is their benefit?
... As regards the fragment "[...]that it is being run in a tight loop", many CPUs have a branch predictor, thus using these macros only helps the first time code is executed or when the history table is overwritten by a different branch with the same index into the branching table. In a tight loop, a...

Mismatch Detected for 'RuntimeLibrary'
.... For example, many of the sources subtly depend upon the latest config.h, cpu.h and cpu.cpp. The "subtlety" is you won't realize you are getting an under-performing class.
An example of under-performing class is BLAKE2. config.h adds compile time ARM-32 and ARM-64 detection. cpu.h and cpu.cpp adds...
Efficient evaluation of a function at every cell of a NumPy array
...ime generated C-function as ufunc
import numba as nb
@nb.vectorize(target="cpu")
def nb_vf(x):
return x+2*x*x+4*x*x*x
It easily beats np.vectorize but also when the same function would be performed as numpy-array multiplication/addition, i.e.
# numpy-functionality
def f(x):
return x+2*x*x...
Why is the JVM stack-based and the Dalvik VM register-based?
...ed design makes very few
assumptions about the target
hardware (registers, CPU features),
so it's easy to implement a VM on a
wide variety of hardware.
Since the operands for instructions
are largely implicit, the object
code will tend to be smaller. This
is important if you're going to be
downloadi...
Difference between float and decimal data type
...s are required of the DB engine to convert the "number" into something the CPU recognizes as a number. No rounding, no conversion errors, it's a real number the CPU can manipulate.
Calculations on this arbitrarily large integer must be done in software, as there is no hardware support for this kin...
