It’s also peculiar because log2f is a C Run-Time (CRT) function, which shouldn’t be supplied by Blink anyway. The symbol search order is unspecified by C++ and due to the One Definition Rule (ODR) the search order should not matter. defined inline log2 and log2f function PeriodicWave.cpp included MathExtra.h

Was there some other program consuming CPU, like a misbehaving Ubuntu service that wasn't in CentOS? As (C) looked like a kernel rebuild, I started with (D) and (E). ## 6. I also rewrote this in C and called gettimeofday(2) directly: $ cat gettimeofdaybench.c top(1) showed that only the Cassandra database was consuming CPU.

It shouldn’t take much C# code to make an app that monitors the root of all drives, using buffer sizes that start small and gradually get larger. The source code for the C# FileSystemWatcher class can be found here. Another instance of this problem was hit in November 2017 and is described here. You know where to find me.

Support For Aspect-Oriented Programming. So, by defining the component hierarchy through dependency-injection or configuration files, the API can be said to support Aspect-oriented programming , “a programming paradigm that aims to increase modularity by allowing the separation of cross-cutting concerns.”.

Fetishizing pair programming. If you were involved with professional programming in the 80s and 90s, you may remember how radical it was (and, in many shops, still is) to put software developers in touch with users and customers. It’s the single most popular programming language on O’Reilly, and it accounts for 10% of all usage.

Our checks are based on well-known problems that arise in experimental design and causal inference… PlanAlyzer checks PlanOut programs for a variety of threats to internal validity, including failures of randomization, treatment assignment, and causal sufficiency. PlanOut itself has been ported many programming languages at this point.

Upon closely examining the user’s Notebook, we noticed a library called pystan , which provides Python bindings to a native C++ library called stan, looked suspicious. This file was introduced in this commit in 2017, with the purpose of improving the performance of user programs that determine aggregate memory statistics.

To simulate text messages I have used ~3 billion of reddit comments (10 years from 2007 to 2017), downloaded from pushshift.io. As a temporary workaround we can do something like this: SELECT count() FROM rc WHERE (created_utc > ( ( SELECT max(created_utc) FROM rc ) - ((60 * 60) * 24))) AND (subreddit = 'programming') ??count()??
