3 ways to copy files in Go
This article will show you how to copy a file in the Go programming language. Although there are more than three ways to copy a file in Go, this article will present the three most common ways: using the io.Copy() function call from the Go library; reading the input file all at once and writing it to another file; and copying the file in small chunks using a buffer.

The life cycle of a software bug
During the process of testing, bugs are reported to the development team. Quality assurance testers describe the bug in as much detail as possible, reporting on their system state, the processes they were undertaking, and how the bug manifested itself.
Despite this, some bugs are never confirmed; they may be reported in testing but can never be reproduced in a controlled environment. In such cases they may not be resolved but are instead closed.
It can be difficult to confirm a computer bug due to the wide array of platforms in use and the many different types of user behavior. Some bugs only occur intermittently or under very specific situations, and others may occur seemingly at random.
Many people use and interact with open source software, and many bugs and issues may be non-repeatable or may not be adequately described. Still, because every user and developer also plays the role of quality assurance tester, at least in part, there is a good chance that bugs will be revealed.

LLVM's OpenMP Offloads Liboffload Into Oblivion
The liboffload library has been dropped from LLVM's OpenMP repository.
Liboffload is/was the Intel runtime library for offloading and geared for supporting the Xeon Phi co-processors. But liboffload within LLVM hasn't been receiving updates, it wasn't properly integrated within the LLVM build system, and unfortunately Xeon Phi co-processors appear to be discontinued. The liboffload library has also confused some with LLVM's libomptarget library for OpenMP support that is in much better shape.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
