Git DMZ Flow

I've been asked a few times over the last few months to put together a full write-up of the Git workflow we use at RichRelevance (and at Precog before), since I have referenced it in passing quite a few times in tweets and in person. The workflow is appreciably different from GitFlow and its derivatives, and thus it brings with it a different set of tradeoffs and optimizations. To that end, it would probably be helpful to go over exactly what workflow benefits I find to be beneficial or even necessary.

  • Two developers working on independent features must never be blocked by each other
    • No code freeze! Ever! For any reason!
  • A developer must be able to base derivative work on another developer's work, without waiting for any third party
  • Two developers working on inter-dependent features (or even the same feature) must be able to do so without interference from (or interfering with) any other parties
  • Developers must be able to work on multiple features simultaneously, or at lea

Indirect vs Direct Function Call Overhead in C/C++
/*
This benchmark shows how indirect function calls have nearly
the same overhead costs as direct function calls.
This is comparing apples to apples, factoring out the savings
due to inlining optimizations that direct calls usually afford.
From this, it seems that inlining and other generic interprocedual
optimizations are the main drivers of direct function call optimization,
not the direct call itself.

Simple wrapper around terraform to manage multiple environments

This script will pull down an S3 remote configuration before running any terraform actions. Assumes the following structure:

main.tf
terraform.cfg
env/dev/vars
env/staging/vars
env/whatever/vars
env/whatever/somefile.tf

Event-stream based GraphQL subscriptions for real-time updates

In this gist I would like to describe an idea for GraphQL subscriptions. It was inspired by conversations about subscriptions in the GraphQL slack channel and different GH issues, like #89 and #411.

Conceptual Model

At the moment GraphQL allows 2 types of queries:

  • query
  • mutation

Reference implementation also adds the third type: subscription. It does not have any semantics yet, so here I would like to propose one possible semantics interpretation and the reasoning behind it.

OpenSSL DTLS API

OpenSSL DTLS API

The API used for DTLS is mostly the same as for TLS, because of the mapping of generic functions to protocol specifc ones. Some additional functions are still necessary, because of the new BIO objects and the timer handling for handshake messages. The generic concept of the API is described in the following sections. Examples of applications using DTLS are available at [9].

DTLS の API は TLS とほぼ同じ。 BIO オブジェクトの生成とタイマのために追加でいくつか必要。

Effective Modern CMake

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft
