Deviceside Software Update Strategies for Automotive Grade Linux
Deviceside Software Update Strategies for Automotive Grade Linux Konsulko Group, sponsored by ATS Advanced Telematic Systems GmbH Overview This whitepaper explores the area of software update strategies for devices running Automotive Grade Linux. The starting point is understanding several key use cases for updating software in an AGL1 system. Several open source deviceside software update mechanisms are compared with a focus on their ability to meet the stated use cases. Finally, recommendations are made for an approach that can be implemented for inclusion in AGL. Use Cases and Requirements The topic of software update on any computing device is very broad and can only be examined properly by narrowing the scope of the system, operating conditions, and the policies established for executing a software update. The following sections describe the use cases considered when evaluating the various mechanisms that could be employed in an AGL software update strategy. System Description AGL systems include both IVI2 and ADAS3 devices that run Linux on at least one processor in the system. The complete IVI or ADAS system is not necessarily limited to a single processing node, but is normally part of a larger network that includes a number of ECU4 nodes throughout the automobile. Due to this distributed architecture it is often necessary to update software on 1 Automotive Grade Linux (https://www.automotivelinux.org/aglspecification) 2 InVehicle Infotainment 3 Advanced Driver Assistance System 4 Electronic Control Unit Copyright 2016 Konsulko Group and ATS Advanced Telematic Systems GmbH CC BYSA 3.0 US (https://creativecommons.org/licenses/bysa/3.0/us/) the ECUs as well as the node running AGL. -

An Analysis of Python's Topics, Trends, and Technologies Through Mining Stack Overflow Discussions

In spite of its ever-growing community, researchers as web programming [4], mobile application development [5], have not performed much analysis on Python’s topics, trends, and tech- security [6], and blockchain [7]. However, none of them has nologies which provides insights for developers about Python commu- focused on Python. In this study, we shed light on the nity trends and main issues. In this article, we examine the main topics Python’s main areas of discussion through mining 2 461 876 related to this language being discussed by developers on one of the most popular Q&A websites, Stack Overflow, as well as temporal trends posts, from August 2008 to January 2019, using LDA based through mining 2 461 876 posts. To be more useful for the software topic modeling . We also analyze the temporal trends of engineers, we study what Python provides as the alternative to popular the extracted topics to find out how the developers’ interest technologies offered by common programming languages like Java. is changing over the time. After explaining the topics and Our results indicate that discussions about Python standard features, trends of Python, we investigate the technologies offered web programming, and scientific programming 1 are the most popular by Python, which are not properly revealed by the topic areas in the Python community. -

Cheriton School of Computer Science University of Waterloo [apokluda | mfbari | r5ahmed | rboutaba]@uwaterloo.ca 2American University of Beirut [email protected] University of Waterloo Technical Report: CS-2013-15∗ ∗This report is a modified version of an internal technical report produced for Orange Labs, the project's sponsor. The original technical report was submitted to Orange Labs in August 2013. Abstract During the main phase of this project we identified and provided solution for the major challenges related to peer-to-peer (P2P) web hosting. More specifically, our solutions for naming, availability, ranking, indexing and dynamic web-hosting have been provided in previous reports. In this report we present a more concrete view of the pWeb infrastructure and address the issues related to a real-life deployment of the system. First we provide an overview of the light-weight P2P communication protocol between pWeb clients for signaling and media streaming in Part I. In Part II we provide an architectural overview of pWeb system and show the mapping of the abstract components in pWeb architec- ture to real life devices and technologies. In order to make pWeb compatible with the existing Web technology we have developed a DNS gateway. In Part II Section 3, we provide the design and implementation of this DNS gateway. For efficient indexing and fast discovery of end-user devices and multimedia content, we have developed a cloud-based solution for crawling, indexing and searching. -

Despite the amount of preparation involved in this transition, it was a rough period to adapt to our new system and still offer the same level of service. Even after the change of system, we faced many unpredictable issues necessitating quick and efficient decisions altering the processes that were previously agreed on. Throughout all these challenges, our team worked together to ensure that we continued to offer the best possible service to you. We thank you for your patience and understanding as we sorted out those issues. Now that we have a solid foundation, we plan to work on numerous other projects that will connect with our ERP database to offer better and quicker solutions to you. During the previous year we have begun offering what we call the “Zoller service” for calibrating CNC tools so that you can save hours when you set up new tools or redressed tools on your CNC machine. If you haven’t heard of this service please ask your local sales and service representative or our customer service agents for more information. -

Hunter Documentation Release 0.23
Hunter Documentation Release 0.23 Ruslan Baratov Aug 20, 2021 Contents 1 Brief overview 3 2 Quick start 15 3 User guides 19 4 Packages 51 5 Creating new package 245 6 FAQ 273 7 Contributing 295 8 Contacts 299 9 Reference 301 Index 345 i ii Hunter Documentation, Release 0.23 Welcome to the Hunter package manager documentation! Hunter is a CMake driven cross-platform package manager for C/C++1 projects. With the help of Hunter you can organize builds for Linux, Windows, macOS, iOS, Android, Raspberry Pi and other platforms. Third-party external projects are highly customizable, effectively allowing you to have myriad variants of directories with them based on combinations of version to build, static/shared, CMake -D options, Release/Debug, etc. Separate root directories will be created for each variant, so they all can be used simultaneously on one machine without conflicts (just like virtualenv but automatically). Going further: each such root directory can be shared between several local projects if configuration of externals matches. So when you are starting another project from scratch and use the same external packages, there will be no additional copy or build triggered; the only overhead is checking the existence of a DONE stamp file for each package. In case your local environment is similar enough to the continuous integration environment of Travis/AppVeyor service, then build will not be triggered at all - cached binaries will be downloaded from GitHub server instead. Mainly Hunter is designed to manage packages with CMake build system under the hood and existing CMake packages can be quite easily integrated into system, but non-CMake packages are also supported too using custom templates (build schemes) with ExternalProject_Add command(s). -
