Automatic verification of software packages with help of DNS
Sehnoutka, Martin ; Dvořák, Jan (referee) ; Jeřábek, Jan (advisor)
Tato diplomová práce se zabývá problémem bezpečné distribuce software. Je navrženo zlepšení s pomocí doménového systému, který je použit pro uložení verifikačních klíčů, potřebných pro ověření integrity balíků stáhnutých pomocí správce balíků. Navíc je navržena rozšířená verze, které se zabývá zabezpečením metadat repositářů. Obě verze jsou implementovány v jazyce Python a integrovány do správce balíků dnf. Tato implementace je otestována ve virtuálním prostředí, diskutována a zhodnocena z hlediska způsobené zátěže.

Modular File Scanner for RPM
Mlčoch, Tomáš ; Smrčka, Aleš (referee) ; Zelený, Jan (advisor)
Balíčkovací systém RPM poskytuje pohodlné řešení pro správu a distribuci softwaru. Z pohledu vývojáře s ním pracujícího, je hlavní činností tvorba balíčků vhodných pro širokou distribuci. Tento proces obnáší řadu činností, které jsou pro velké množství softwaru podobné, či zcela totožné. Bylo by tedy vhodné mít možnost, tyto opakované činnosti co nejvíce a nejjednodušeji zautomatizovat, aby se usnadnila práce vývojářům a zmenšil prostor pro možné chyby. Cílem této práce je analýza požadavků, návrh a implementace modulárního skeneru do nástroje rpmbuild - části RPM starající se o tvorbu balíčků. Tento modulární skener bude poskytovat API ke sledování a modifikaci procesu sestavování balíčku a umožní snadnou tvorbu modulů doplňujících funkcionalitu pro zjednodušení a zefektivnění procesu balíčkování.

A File System Implementing Storage for Gentoo Portage Based on a Relational Database
Štulpa, Adam ; Mlích, Jozef (referee) ; Rychlý, Marek (advisor)
The thesis deals with implementation of a program which can, through the use of FUSE library, make data accessible in the relational database like the classical Gentoo Portage storage. First, the reader of the thesis becomes familiar with FUSE library itself. After that, the new data model is built based on the analysis of the Portage structure. The new model emphasizes especially dependencies of packages. The key implementation issues are also described in the next part. Finally, the thesis assesses outcomes achieved including comparison with standard Portage implementation and classical file system. The other possibilities of the project development are considered as well.

The PXA270M ARM module and its usage as private branch exchange
Vojtíšek, Jindřich ; Šilhavý, Pavel (referee) ; Daněček, Vít (advisor)
This work deals with using the operating system Linux on diskless devices. This is solved on the development kit Voipac PXA270M, which is based on the ARM processor. This work deals further with the distributions of the Linux operating system, which are suitable to use for the device based on the ARM processor. The Linux was chosen because it is one of the most flexible operating systems and the Linux is kept as open source software code, except to the distribution of the Red hat and a few special distributions. The NFS protocol and TFTP are described there. The TFTP and NFS are used to deploy the operating system. It describes there, what are the TFTP and NFS and the principle of their use in computer networks. Practical part is as to, what is needed for the functioning of the TFTP and NFS server on the Ubuntu 11.10 plus how configure them. The OpenOCD is another part of this work. The OpenOCD is designed to work in the device memory. There is shown how to install and run the OpenOCD in order to communicate with the development kit Voipac PXA270M. This work shows how to configure the bootloader U-boot for booting the operating system from the network using the NFS and TFTP. There is described how compile and install PBX Asterisk on Voipac PXA270M with use of cross compiler and how cross compile zlib, OpenSSL and ncurses needed to install nad run Asterisk.

Continuous Integration and Delivery by Nix/NixOps in Software Development
Vlk, Tomáš ; Burget, Radek (referee) ; Rychlý, Marek (advisor)
This thesis deals with the application of the functional packaging system Nix and its ecosystem (NixOS, NixOps) for CI/CD in agile development. When using these technologies, the problems caused by different environments are virtually eliminated without the need of containerization. The thesis contains a description of the possibilities and the shortcomings of Nix/NixOps and it proposes a general procedure for the use of these technologies in individual phases of agile development and CI/CD. Thanks to Nix/NixOps, the implementation of CI/CD is very simple and the whole process is also reproducible. The output of the work is a set of the examples demonstrating the use of Nix/NixOps in various projects, which is available as open-source. Thanks to this set, the developers can use Nix quickly and easily in any project, without having to study a large amount of materials.

New Design and Implementation of RPM Database
Zelený, Jan ; Smrčka, Aleš (referee) ; Peringer, Petr (advisor)
Package management systems are very effective and comfortable solution of installing, maintaining and erasing software from computer. Their basic idea is that all information about installed software is kept in one place and is managed by common utilities. RPM database is such place, where information are being kept. Currently used solution is obsolete and needs some improvements. This thesis analyzes current solution, possible alternative options and based on this a new database design is proposed. A prototype implementation is also included and it is compared with current solution.

A File System Implementing Storage for Gentoo Portage Based on a Relational Database
Štulpa, Adam ; Weiss, Petr (referee) ; Rychlý, Marek (advisor)
The thesis deals with an implementation of a program, which can make the data in relational database available as the standard storage Gentoo Portage with the assistance of FUSE library. The reader is initially familiarised with its structure. There is an analysis of the requirements on the program and the database described in the work. Furthermore, their proposal is given and in the penultimate chapter, there is described the implementation of the program. In the conclusion, there are all the outcomes evaluated including the comparison with the standard file system and further development possibilities of the project are also described.

Development of Web Single Page Applications using a promising micro-frontend technique.
VRBA, Petr
The point of the bachelors thesis is to process problematics of the Single Page Applications (SPA further) websites development using promising micro-frontend technologies. Using of micro-frontend technologies for SPA allows processing of data and website content without need of webpage refresh. They are concurrently promising method, how to realize more complex aplications without server overload, thanks to division of labor between server and clients browser. The content of the theoretical part will be focused on meaning and specifications of SPA and micro-frontend, then presentation of specific JavaScript frameworks. In the theoretical part will be presented functionality and the importance of packaging systems for SPA also. The main result of the work will be SPA website demonstrating usement of micro-frontend technologies on specific examples and functionalities. The website will be used as first public documentation in czech language, dedicate with Single Page Applications using micro-frontend, which will be able to be used by IT professionals and students.
