  • Bebras International Workshop 2020 Delegates’ Guidelines for Working Groups
    Bebras International Workshop 2020 Delegates’ Guidelines for Working Groups Preparation for Working Group Participation Please read through this document thoroughly in order to make your work for the Bebras Workshop more efficient. Prepare Your Workplace You will need to have the following installed and running: ● A recent computer. ​ ​ ● A working microphone. ​ ​ ● If possible a webcam. ​ ​ ● A proper up-to-date web browser (for this year Chrome or Chromium derivatives like Vivaldi are ​ ​ preferred for compatibility reasons). ● A SVN client (except for guests or representatives without SVN access1). ​ ​ ○ Windows: TortoiseSVN is recommended (https://tortoisesvn.net/). ​ ​ ○ macOS: either use the command line (if you’re comfortable with it) or consider Versions https://versionsapp.com/ (not free); some people have also used integrated development ​ environments that offer SVN functionality; some people even run a virtualized Windows just for TortoiseSVN. ○ Linux: you know what you’re doing, right? ● LibreOffice 6.3 or 6.4 (https://www.libreoffice.org/download/download/). Older versions become ​ ​ ​ increasingly incompatible. OpenOffice is no longer an alternative. ● A proper text editor (not Word or LibreOffice but for HTML source code editing) ​ ​ ○ Windows: Notepad++ is recommended (https://notepad-plus-plus.org/downloads/). ​ ​ ○ macOS: TextWrangler 5.5.2 was recommended for pre-macOS 10.15, Atom is also working with macOS 10.15 (https://atom.io/). ​ ​ ○ Linux: you know what you’re doing, right? ● Our video conferencing tool for the working groups (a local installation of Jitsi Meet available at ​ ​ https://workshop.cuttle.org/BebrasYourRoomName ) will run fine in any web browser. There is an ​ ​ electron app available (https://github.com/jitsi/jitsi-meet-electron/releases), but watch out for ​ ​ security problems with electron apps because they tend to bundle older chromium versions with security problems.

  • An Overview of Platforms for Cloud Based Development G
    Fylaktopoulos et al. SpringerPlus (2016) 5:38 DOI 10.1186/s40064-016-1688-5 REVIEW Open Access An overview of platforms for cloud based development G. Fylaktopoulos1, G. Goumas2, M. Skolarikis1, A. Sotiropoulos3 and I. Maglogiannis4* Abstract This paper provides an overview of the state of the art technologies for software development in cloud environments. The surveyed systems cover the whole spectrum of cloud-based development including integrated programming environments, code repositories, software modeling, composition and documentation tools, and application man- agement and orchestration. In this work we evaluate the existing cloud development ecosystem based on a wide number of characteristics like applicability (e.g. programming and database technologies supported), productiv- ity enhancement (e.g. editor capabilities, debugging tools), support for collaboration (e.g. repository functionality, version control) and post-development application hosting and we compare the surveyed systems. The conducted survey proves that software engineering in the cloud era has made its initial steps showing potential to provide con- crete implementation and execution environments for cloud-based applications. However, a number of important challenges need to be addressed for this approach to be viable. These challenges are discussed in the article, while a conclusion is drawn that although several steps have been made, a compact and reliable solution does not yet exist. Keywords: Cloud computing, Integrated Development Environment (IDE), Code repositories, Software modeling, Orchestration tools Background application side, large families of applications including Within the past few years, cloud computing has emerged desktop, business, entertainment (Simmhan et al. 2010; as a dominant computing model in IT infrastructures, Schmidt 2012; Hobfeld et al.

  • Polishing Zulip (Electron) Making the Desktop Client an Obvious Choice for Zulip Users
    Kanishk Kakar [email protected] github.com/kanishk98 GMT +05:30 India, fluent in English Polishing Zulip (Electron) Making the desktop client an obvious choice for Zulip users ABSTRACT With its innovative threading model and robust webapp, Zulip has received a lot of praise from remote teams that use it. While the desktop app is certainly complete in terms of features, it needs some polish and certain standout features to make it an obvious choice for a Zulip user to install. In this proposal, I suggest the implementation of multiple features to achieve the above goal. PROPOSED DELIVERABLES By the end of the summer, I intend to have implemented the following features: Enterprise deployment Currently, there is no Zulip-enabled way for admins to deploy the app with custom settings for multiple users in an enterprise setting. After ​discussions​ with the community, I’ve been working with Vipul Sharma to implement a system that allows the admin to write a script for configuring the app as they require via a .json file in the root directory. My role so far while developing this feature has been to add an ​ ​EnterpriseUtil ​module ​ that configures settings at various places in the app and allows admins to also configure whether keeping a setting admin-only is required or not. I expect to have completed this feature before the community bonding period begins. WIP PR #681 Replacing​ <webview> with​ BrowserView ​ ​ We currently use <​ webview> ​for rendering all content except the sidebar in the app window. ​ However, the Electron team has ​warned​ developers against using <​ webview>​ because of certain persistent bugs.

The last six months have exposed and magnified long standing inequities -- in our communities, in our hospitals, in our workplaces, and in schools. Too many of our school districts lack a fair share of resources to address the pandemic’s challenges; not every student can be taught remotely with attention to their need for social and emotional safe learning spaces. The current circumstances are poised to exacerbate existing disparities in academic opportunity and performance, particularly between white communities and communities of color.

  • Linux Online Virtual Environments in Teaching Operating Systems
    Linux Online Virtual Environments in Teaching Operating Systems Olena Holovnia[0000-0003-0095-7585] Zhytomyr Polytechnic State University, 103, Chudnivska str., Zhytomyr, 10005, Ukraine [email protected] Abstract. The article provides an overview of Linux ready-made online environments based on various virtualization technologies. Linux ready-made online virtual environments are systematized, the advantages and disadvantages of considering groups of online virtual environments are listed. The work also gives the comparison of standalone online Unix/Linux terminals in terms of their possible use for a course in operating systems. The author analyzes the experience of teaching a Linux operating system to students of different specializations, and in particular, discusses the virtualization tools used, including Linux online environments (Amazon EC2, Cloud 9, a virtual machine for NDG Linux Essentials course). The study states the need for developing an individually designed system to provide Linux online virtual environments and elaborates the requirements to this system. The work also discusses potential challenges which the developers of Linux online virtual environments for teaching operating systems may face, including the problem of finding a balance between availability and stability of virtual environments on the one hand and the realism of students’ learning experience on the other hand. Keywords: virtualization, Linux, operating systems. 1 Introduction A course in operating systems (OS) usually includes practical assignments on Unix- like operating systems (particularly, Linux). However, at the same time, university lab computers, students’ laptops and home desktop computers mostly come with Windows installation. That is one important reason why different virtualization technologies are often used for a course in operating systems.

There are several open source based solutions and tools available for each category but a coherent whole is still missing. 2021 3 Purpose and aim of the project The purpose in the first phase of the project was to conduct a preliminary study on how single open source based solutions and tools could be combined to a comprehensive joint solution and research the technical compatibility between the different OS solutions. The project aims to create a comprehensive example solution that is based on open source components.
