A Classical Introduction to Modern Number Theory, Kenneth Ireland Michael Rosen

via (https://www.linux.com/learn/tutorials/442438-vim-tips-folding-fun)

zf#j creates a fold from the cursor down # lines.
zf/string creates a fold from the cursor to string .
zj moves the cursor to the next fold.
zk moves the cursor to the previous fold.
zo opens a fold at the cursor.
zO opens all folds at the cursor.
zm increases the foldlevel by one.
zM closes all open folds.

Comparative Benchmark Numbers @ Rackspace

I've taken the benchmarks from Matthew Rothenberg's phoenix-showdown, updated Phoenix to 0.13.1 and ran the tests on the most powerful machines available at Rackspace.

Results

Framework	Throughput (req/s)	Latency (ms)	Consistency (σ ms)

Prerequisites

Homebrew
Python 2.7
Git

Graphite

Install Cairo

There's an issue with cairo 14.x that results in the axis fonts on the graphs being HUUUUUGE. Downgrading to 12.6 helps:

Erlang QuickCheck

What is QuickCheck?

QuickCheck is a language for stating properties of programs.

?FORALL(X, nat(), X*X >= 0)

Feedback on the QuickCheck model

So, we have a QuickCheck model at

https://github.com/cmeiklejohn/derflow/blob/master/test/derflow_ets_eqc.erl

and Chris is asking for feedback, so here goes the things I've seen in this model. This is just haphazardly written, so don't expect there to be much flow in the thing.

	// The stack is 8-byte aligned.
	#define ALIGN(p) ((uint64_t *)(((uintptr_t)(p) + 7) & ~7))
	#define STACK(stack, size) uint64_t _stack = ALIGN(stack), _stack_end = (uint64_t )((char )(stack) + size)
	#define PUSH(x) do { memcpy(_stack, &x, sizeof(x)); _stack += (sizeof(x) + 7) / 8; } while (0)
	#define POP(x) do { _stack -= (sizeof(x) + 7) / 8; memcpy(&x, _stack, sizeof(x)); } while (0)

	#if __GNUC__
	// Use computed gotos on GCC-compatible compilers (including Clang).
	#define JOIN(x, y) x##y
	#define LABEL(name) JOIN(label, name)
