arrayfun can be significantly slower than an explicit loop in matlab. Why?
...s as fast as the fully vectorized version... That was all done on a single CPU. Results for Soln5 and Soln7 do not change if I switch to 2 cores - In Soln5 I would have to use a parfor to get it parallelized. Forget about speedup... Soln7 does not run in parallel because arrayfun does not run in pa...
Canary release strategy vs. Blue/Green
...to get an idea of how new version will perform (integrate with other apps, CPU, memory, disk usage, etc).
Blue/Green:
It is more about the predictable release with zero downtime deployment.
Easy rollbacks in case of failure.
Completely automated deployment process

Why use the INCLUDE clause when creating an index?
...mns while already updating the index. The overhead is the extra memory and CPU used to store redundant info on the index.
If the columns you consider to add as included-columns are often updated (without the index-key-columns being updated) - or - if it is so many of them that the index becomes clo...

Is it possible to “decompile” a Windows .exe? Or at least view the Assembly?
...roach. Variable names are non-existent; such a thing doesn't exist to your CPU. Library calls are confusing as hell and often require disassembling further binaries. And assembly is hard as hell to read in the best of conditions.
Most professional programmers can't sit and read assembly language wi...
Why doesn't .NET/C# optimize for tail-call recursion?
...what I know.
Sometimes tailcall is a performance win-win. It can save CPU. jmp is
cheaper than call/ret It can save stack. Touching less stack makes for
better locality.
Sometimes tailcall is a performance loss, stack win.
