used by many of Google’s open- source projects. As every C++ programmer knows, the language has many powerful features, but this power brings with it complexity, which in turn can make code more bug-prone These rules exist to keep the code base manageable while still allowing coders to use C++ language features produc- tively. Style, also known as readability, is what we call the conventions that govern guide. Note that this guide is not a C++ tutorial: we assume that the reader is familiar with the language. Goals of the Style Guide Why do we have this document? There are a few core goals that we believe

as the complete definition of Google’s coding standards for source code in the Java™ Programming Language. A Java source file is described as being in Google Style if and only if it adheres to the rules order its members in some logical order, which its maintainer could explain if asked. For example, new methods are not just habitually added to the end of the class, as that would yield “chronological by followed by else or a comma. Examples: return () -> { while (condition()) { method(); } }; return new MyClass() { @Override public void method() { if (condition()) { try { something(); } catch (ProblemException

Google’s R Style Guide Google’s R Style Guide R is a high-level programming language used primarily for statistical computing and graphics. The goal of the R Programming Style Guide is to make our R Calls 13. Function Documentation 14. Example Function 15. TODO Style: TODO(username) Summary: R Language Rules 1. attach: avoid using it 2. Functions: errors should be raised using stop() 3. Objects and xor (but not both) if (is.null(ylim)) ylim <- c(0, 0.06) Always begin the body of a block on a new line. BAD: if (is.null(ylim)) ylim <- c(0, 0.06) if (is.null(ylim)) {ylim <- c(0, 0.06)} Surround

Recommendation  HW components: #nodes, CPUs, memory, network, I/O  SW components: OS, programming language, versions, other software  Baselines and configuration  Use recent versions of baseline systems plots, and finally, 5. recompiles the sources of the paper ... to produce a new PDF for the paper that contains the new graphs. “  Note: It takes time, plan from start  We prepared for SIGMOD 2019

 Plural allows to drop articles  Use guarded spaces for references that should not appear on a new line  Clear References  Make sure there are no unclear “it” or “this” references  Add descriptive
