An assertion documents the expected state of specific program variables at the point where the assertion is written, in a testable way so that we can find program bugs — logic errors that have led to corrupted program state. Assertions are only about finding bugs, not doing program work. Bonus: [[assert: ?

C++ “move” semantics are simple, and unchanged since C++11. Move: What it is, and how to use it In C++, copying or moving from an object a to an object b sets b to a ’s original value. This post is an attempt to shed light on that situation. That’s it for what advanced users need to know. Yes, but don’t.

Embedded C. # # Tone generation from: [link] # # 29-Apr-2019 Brendan Gregg Created this. This is the culmination of five years of work: the BPF kernel runtime, C support, LLVM and Clang support, the BCC front-end, and finally the bpftrace language. This is not my best code, since I hacked it in a hurry, but here it is: #!/usr/bin/python

This can be changed later using the pg_checksums utility, but that will be a painful exercise on a big database. psql "host=localhost user=postgres options='-c synchronous_commit=off'" psql (14.8) Object-level settings PostgreSQL allows us to specify the parameter specific to a program block, like a PL/pgSQL function.

Humans are biologically programmed to mistrust anything that deviates from the status quo. A Value Stream Architecture (VSA) diagram can provide that visual cue: A Value Stream Architecture exercise maps the flow of value-creating and -protecting software delivery work across your toolchain that underpins your product value stream.

The mock development environment is shown below: Once a model has been created, it can be tested using a client test program that sends messages that simulate the behavior of one or more data sources.

On the last morning of the conference Daniel Bittman presented some of the work being done in the context of the Twizzler OS project to explore new programming models for NVM. The starting point is a set of three asumptions for an NVM-based programming model: Compared to traditional persistent media, NVM is fast. What about security?

This ruling in itself raises many questions: how much creativity is needed, and is that the same kind of creativity that an artist exercises with a paintbrush? If a human writes software to generate prompts that in turn generate an image, is that copyrightable? For a company like O’Reilly Media, a related question comes into play.

At the lowest level, all computers are programmed with strings of ones and zeroes. When you program in machine language, you are controlling the computer at its brainstem, the root of its existence. So a whole Babel of computer languages has been created for programmers: FORTRAN, BASIC, COBOL, LISP, Pascal, C, PROLOG, FORTH.

There was no deep goal — just a desire to see the maximum GFLOPS in action. The exercise seemed simple enough — just fix one item in the Colfax code and we should be finished. After this, the micro-ops will wait in the Reorder Buffer until they can be retired in program order. Instead, we found puzzle after puzzle.
