Gitmate Let's Write Good Code!
GitMate Let's Write Good Code! Artwork by Ankit, published under CC0. Vision Today's world is driven by software. We are able to solve increasingly complex problems with only a few lines of code. However, with increasing complexity, code quality becomes an issue that needs to be dealt with to ensure that the software works as intended. Code reviews have become a popular tool to keep the quality up and problems solvable. They make out at least 30% of the amount of time spent on the development of a software product. Static code analysis and code reviews are converging areas. Still, they are still treated seperately and thus their full synergetic potential remains unused. With GitMate, we want to reinvent the code review process. Our product will integrate static code analysis directly into the code review process to reduce the number of bugs while leaving more time for the development of your favorite features. Our product, the interactive code review bot "GitMate", is not only an easily usable static code analyser, but also actively supports the development process without any overhead for the developer. GitMate is as easy to use and interact with as a collegue next door and unique in its capabilities to even fix bugs by itself. It thereby reduces the amount of work of the reviewer, allowing him to focus on semantic problems that cannot be solved automatically. Product GitMate is a code review bot. It uses coala [1] to perform static code analysis on GitHub Pull Requests [2]. It searches committed changes for possible problems and drops comments right in the GitHub review user interface, effectively following the same workflow of a human reviewer. -

Researchers analyze content on these sites to learn about trends To address this gap we present a novel source of long-form and topics in software engineering. However, insight mined text data created by people working in software called DEV from the text of Stack Overflow questions or GitHub issues (https://dev.to). DEV is “a community of software developers is highly focused on detailed and technical aspects of software getting together to help one another out,” focused especially development. In this paper, we present a relatively new online on facilitating cooperation and learning. Content on DEV community for software developers called DEV.

How Are Issue Reports Discussed in Gitter Chat Rooms?
How are issue reports discussed in Gitter chat rooms? Hareem Sahar1, Abram Hindle1, Cor-Paul Bezemer2 University of Alberta Edmonton, Canada Abstract Informal communication channels like mailing lists, IRC and instant messaging play a vital role in open source software development by facilitating communica- tion within geographically diverse project teams e.g., to discuss issue reports to facilitate the bug-fixing process. More recently, chat systems like Slack and Git- ter have gained a lot of popularity and developers are rapidly adopting them. Gitter is a chat system that is specifically designed to address the needs of GitHub users. Gitter hosts project-based asynchronous chats which foster fre- quent project discussions among participants. Developer discussions contain a wealth of information such as the rationale behind decisions made during the evolution of a project. In this study, we explore 24 open source project chat rooms that are hosted on Gitter, containing a total of 3,133,106 messages and 14,096 issue references. We manually analyze the contents of chat room discus- sions around 457 issue reports. The results of our study show the prevalence of issue discussions on Gitter, and that the discussed issue reports have a longer resolution time than the issue reports that are never brought on Gitter.

Introduction Open source software (OSS) development uses the expertise of developers from all over the world, who communicate with each other via email, mailing lists [1], IRC channels [2], and modern communication platforms like Gitter 5 and Slack [3]. -

Introduction to Linux Operating System Table of Contents
Introduction to Linux Operating System Table of contents • Operating system tasks • UNIX history, Linux history • Linux basic features • Linux distributions • Building OS kernels • Linux modules • eBPF • Linux structure and kernel functions • Basic concepts – process, user mode and kernel mode, context switch, system calls, user stack and kernel stack, process state transitions • Kernel reports – what is going on in the kernel • Additional reading 2 Operating system tasks Operating System is a program that mediates between user and computer hardware. • Hides hardware details of the computer system by creating abstractions (virtual machines). Examples: – a unified way to access external devices, – sets of disk blocks seen as files with symbolic names, – large, fast, dedicated operating memory, – concurrent program execution (as an abstraction of parallelism), – a container provides OS-level virtualization by abstracting the „user space”. • Manages resources: – resources are objects necessary to execute the program, e.g. memory, processor (CPU), input/output, communication ports, – strategies for allocation and deallocation of resources (memory management, processor management, file management, device management), – efficiency of resource management determines efficient operation of computer hardware. • Provides a friendly interface. 3 Computer system layers (source: Stallings, Operating Systems) 4 UNIX history • Created in 1969; authors: Ken Thompson, Denis Ritchie from Bell Laboratories, machine: PDP-7, which had many features of MULTICS. -
