When should I use Lazy?
... I believe the main trade-off is between memory usage (lazy) and cpu usage (not-lazy). Because lazy has to do some extra book-keeping, InitLazy would use more memory than the other solutions. It also might have a minor performance hit on each access, while it checks whether it already has ...
Structs versus classes
... as simple a guarantee of correctness as I can and hence not have to waste CPU cycles and brain cycles on checks and edge-cases, and being appropriately mutable or immutable helps there), but it would counter any knee-jerk reaction to your saying immutability can be slower.

What is the list of possible values for navigator.platform as of today? [closed]
...his definition is a bit vague. A decade ago a 'platform' would either be a CPU architecture or an operating system. In recent years handheld and media devices can be platforms too.

What's the use of Jade or Handlebars when writing AngularJs apps
...l. Mentally parsing a JADE template vs. raw HTML requires equal 'wetware' cpu time for me. I won't go so far as to say you're unprofessional if you disagree, but to me it's the same thing. @ Philipp, your analogy of parsing C/C++ to assembly being equal to parsing JADE to HTML is poor, there are ...
Why is SSE scalar sqrt(x) slower than rsqrt(x) * x?
...lers like clang choose not to use reciprocal + Newton for scalar on recent CPUs, because it's usually not faster. In most loops, div isn't the only operation, so total uop throughput is often the bottleneck even when there's a divps or divss. See Floating point division vs floating point multiplic...
What is the memory consumption of an object in Java?
... memory alignment done by a particular JVM implementation for a particular CPU type. It looks like a Long is 8 bytes of Object overhead, plus 8 bytes more for the actual long value. In contrast, Integer had an unused 4-byte hole, most likely because the JVM I use forces object alignment on an 8-byte...

Then, whenever you need to push cpu intensive or blocking code off the event loop thread, you can put it in a decorated function:

Why is lazy evaluation useful?
...
Lazy evaluation related to CPU the same way as garbage collection related to RAM. GC allows you to pretend that you have unlimited amount of memory and thus request as many objects in memory as you need. Runtime will automatically reclaim unusable obje...
