With open source router firmware being used for various tasks that would be hard to achieve for the standard closed source router firmware, it is important to compare the two in terms of performance. This study aimed to study the differences in performance between open source router firmware and that of closed source router firmware. In addition to have measured bandwidth, packet loss and response time has also been measured in order to make it easier for companies/people to make informed decisions regarding whether to use open source router firmware or not. To further help with decision making, a qualitative study was made to gather data regarding how easy each firmware is to configure and how secure they are. There were some larger differences between the open source router firmware and that of the closed source router firmware. The closed source router firmware performed better when it came to bandwidth, whereas the open source firmware got better response time and overall better stability.

With IPv4 addresses running out there is a need for IPv6 compatible routers. This study aims to find open source routers that have support for IPv6 and compare it in terms of performance to IPv4 to see if there are any differences in performance. In addition to this the chosen routers have also been evaluated in terms of security and other desired features. An experiment and a theoretical study evaluating this was carried out to help companies and individuals wanting to use IPv6 make choices in what open source router to use. Different performance factors were taken in to consideration as well as security features. There were no significant differences between IPv6 and IPv4 with IPv4 slightly beating IPv6. Between the routers there were some differences with the VyOS router outperforming pfSense in terms of throughput but pfSense had lower latency values. Depending on the requirements for a specific network environment the results of this study could be used to pick an IPv6-enabled open source router distribution.

Parkeringsproblemet finns i storstäder över hela världen. Med fler människor som skaffar bilar och större städer som inte hinner med i utvecklingen av stadsplaneringen så kommer problemen att öka. Felparkeringsavgifterna i Sverige ökar år efter år och datumparkering är en stor del av det i Gävle. Syftet med arbetet är att utveckla en prototyp på en parkeringsapplikation som på ett enkelt sätt visualiserar var det är tillåtet att parkera. Ett annat delsyfte är att undersöka vad bilförare kan om datumparkering och om en applikation kan hjälpa till att lokalisera platser där det är tillåtet att parkera. Frågan är om det finns data för parkeringar tillgängligt som går att använda i prototypen, en ytterligare sak som ska undersökas vad för existerande lösningar för parkeringsproblem som finns. Existerande lösningar för parkeringar är huvudsakligen inriktade mot parkeringshus och större parkeringar. De applikationer som finns visualiserar dessutom bara med skyltar. Det finns inget data specifikt för gatuparkeringar, därför skapades eget data utifrån Lantmäteriets kartor. Prototypen utvecklas som en webbanpassad applikation med open-source javascript-bibliotek för funktionalitet. Det egengjorda datat laddas in på kartan som vektorlager och får stil beroende på vad för det är för attribut. Linjerna ändras dynamiskt när datumparkering träder in och ändras sedan tillbaka. Målet med applikationen är att öka kunskapen om parkering och regler för att minska felparkeringar och hjälpa att hitta parkering.

Contemporary cases of crowdsourcing (CS) and open source development (OS) related to drug development have been selected and studied. Contemporary examples of CS/OS from within and outside of the pharmaceutical industries have been presented to give a background and suggest possible benefits and problems. The main criteria for selection have been that the case must seek to advance drug development and must use crowdsourcing or open source as a mechanism. The cases found in our search show a large diversity in terms of application, usage, and possible implications for the pharmaceutical industry. We found that crowdsourcing within a scientific problem context produced good results, but that open source initiatives were either poorly financed and not successful or focused on neglected diseases made possible through strong backing by non-profit organizations. An analysis of which the pharmaceutical companies where that showed activity on the platforms identified R&D-intensive and biotech companies as the most active. Contract research organizations (CROs) and generics manufacturers (GMs) showed almost complete absence. We argue that GMs are not likely to be interested in this kind of R&D, but CROs are an untapped resource. Finally we propose a hypothetical model that takes into account all the findings from our study and the literature. This model is based on a limited type of open source with a limited number of partners making use of the untapped CRO resource through crowdsourcing. / Ett antal pågående fall av samverkans-modellen crowdsourcing (CS) samt fenomenet av ”öppen-innovation”, open-innovation (OI) har studerats i kontexten läkemedelsutveckling. I denna fall-studien presenteras ett antal fall där CS och OI används både inom och utom läkemedelsindustrin. Detta har gjorts för att skapa en bättre förståelse för fenomenen samt att tydliggöra problem och att belysa fördela med öppen-innovation och olika typer av samverkans-modeller. Huvudkriteriet för utvalen av fall har varit ett avancerat stadium i läkemedelsutvecklingen samt att något av de två verktygen OI eller CS används aktivt i utvecklingsarbetet. Fall-studien klargör en tydlig differens mellan olika applikations-typer och hur man i verkligheten implementerar dessa verktyg i forskningsarbete. Vår fall-studie indikerar goda resultat då man använder samverkans-modellen CS inom forskningsarbete, men att ”öppen-innovation” OI inte gav samma goda resultat då immateriella mekanismer bromsar öppenheten i läkemedelsindustrin. Inom läkemedels-utvecklingen för Negleted Diseases fann vi däremot en större aktivitet vilken grundar sig på icke-vinst-drivande aktörers intressen. Genom en analys av aktörer inom läkemedelsindustrin har vi kunna framtyda att forsknings-och utveckligns-företag samt Biotech som de som mest ser och utnyttjar potentiallen i CS och OI. Contract research organizations (CROs) och Generics Manufacturers (GMs) är nästan uteslutande frånvarande i resultaten från vår analys. Våra resultat visar att GM-företagen inte har mycket intresse av varken CS eller OI, men att för CRO-företagen finns det vinning i att utnyttja dessa resurser. Slutligen förespråkar vi en fortsatt forskning i ämnet baserat på fall-studien för att kunna ta fram en hypotetisk-CS modell, vilken skulle baseras på ett begränsat antal av samarbetspartners vars potentiella vinning skulle visas genom utnyttjandet av samverkans-modellen CS. / Johan Evaldsson +733-706822

As the performance of PCs is increasing it is of great interest to use these cheap devices as routers,which traditionally consisted of more expensive and customized hardware for that purpose. Thesoftware was also traditionally proprietary and thereby costly, but as the open source communityhas grown there have been development of open source solutions that can perform the task ofacting as a router. However as there are so many solutions out there, it can be hard for the potentialusers to choose which particular solution to use, without having to put in too much work intogetting a fully functional router solution. This study achieved this purpose by benchmarking themost popular open source software routers, in terms of performance and scalability as well asproviding a brief analysis of their basic security features. The routers that were studied wasClearOS, Untangle NG Firewall and IPFire, and after the study was complete IPFire was consideredthe superior with ClearOS as the second and Untangle as third and last.

Les FabLabs, les hackerspaces et les makerspaces sont des ateliers collectifs équipés de machines à commandes numériques et organisés en réseau. Ces lieux s’inscrivent dans l’élan du mouvement maker et dans l’héritage des hackers. Ils se présentent comme des espaces ouverts à tous et pour tout faire. Malgré une forte médiatisation, la réalité des discours et des pratiques qui s’y développent est encore peu étudiée. Cette thèse en esthétique et en design s’appuie sur une vaste enquête ethnographique menée de 2012 à 2015 au coeur de ces communautés, en France et à l’étranger.De nombreux entretiens et observations dessinées permettent une description critique des manières de faire rencontrées sur ces terrains.Les pratiques, les discours et les ambitions de la fabrication numérique personnelle se construisent dans les marges des territoires classiques de l’industrie et du design et en brouillent les cadres historiques. La première partie de la thèse retrace les origines des mouvements maker et hacker et des FabLabs. En s’appuyant sur des données de première mains et sur des récits plus classiques, elle montre comment la contre-culture américaine et les ambitions technophilesdes chercheurs du MIT rencontrent des appropriations locales divergentes.La réhabilitation du plaisir au travail et l’héritage des Arts and Crafts sont deux aspects qui permettent d’envisager ces lieux comme des terrains d’expérimentation sociale, au-delà de la stricte production. Dans la deuxième partie, la thèse se concentre sur les valeurs d’ouverture et de partage prônées par les amateurs, bricoleurs, makers ou inventeurs contemporains. L’hypothèse d’un design ouvert et participatif conçu hors des standards de la production industrielle de masse est examinée. L’« open design » place la production d’objets dans le sillage de l’open source. Les résultats de ce type de production dessinent les contours encore fl ous d’un territoire nouveau pour le design.La troisième partie étudie les promesses et contradictions qui entourent la démocratisation de l’innovation et de la production. L’impression 3D est prise comme cas d’étude emblématique pour étudier les ambivalences de l’émancipation espérée par les porteparoles du mouvement maker. Ces pratiques hésitantes nourrissent les ramifi cations de ce que nous proposons d’appeler un design diffus. Celui-ci se développe par tâtonnements dans les communautés d’amateurs et touche à des activités créatives d’invention, de Conception et de fabrication.L’étendue rhizomatique des manières de faire propresau design diff us est composée d’objets sans apparat,situés dans les marges de l’industrie. Selon la défi nitionqui en est proposée, ils sont conçus de manière ouverteet documentée dans l’objectif d’explorer et de contribuerà la découverte des technologies de la fabricationnumérique personnelle. Sans constituer de paradigmeclos, le design diff us détourne les normes instituées etles procédures classiques du design et de l’industriepour proposer une conception exploratoire et ouverte dela fabrication. / FabLabs, hackerspaces and makerspaces are shared workshops, equipped with digital tools and organised in a network. These places are connected to the maker movement and are heirs to hackers.They off er themselves as places where anybody can come and make anything. In spite of some strong media coverage, the reality of discourses and practices that occur in those places has not yet been much studied. This dissertation in Aesthetics and design is based on a large ethnographic survey conducted between 2012 and 2015, in France and abroad. A series of interviews and drawn observations allows for a critical description of the ways of doing that can be witnessed on these fields. Practices, discourses and ambitions of personal digital fabrication are built in the margins of the classical fields of industry and design, blurring their historical frames. The fi rst part of this dissertation retraces the origins of FabLabs as well as of the maker and hacker movements. First hand data and classical accounts reveal how American counter-culture and the technophile ambitions of MIT researchers result in diverging local appropriations.The rehabilitation of pleasure at work and the heritage of the Arts and Crafts both point to these places as fields ofsocial experimentation, beyond mere production. In the second part, this dissertation focuses on the values of openness and sharing advocated by contemporary amateurs, tinkerers, makers or inventors. The hypothesis of a design that could be open, participative, out of the standards of industrial mass production is examined. « Open design » places the production of artefacts in the wake of open source. This type of production ends up shaping a new, though hazy, field for design.The third part studies the promises and contradictions that surround the democratization of innovation and production. 3D printing is taken as an emblematic case study to consider the ambivalences behind the emancipation expected by representatives of the maker movement.These indecisive practices feed the branches of what we might call 'diff use design'. It develops itself by trial and error in amateur communities and reaches creative activities of invention, conception and fabrication. The rhizomatic area of diff use design comprises rather plain objects, situated in the margins of industry. According to this defi nition, they are produced in an open and documented way, in order to explore and contribute to the discovery of digital fabricationtechnologies. Diff use design is not a closed paradigm, but turns away from instituted norms and off ers an openand exploratory conception of fabrication.

The diploma thesis called The Analysis of 3D printing use in households is dealing with the current topic of 3D printers and examines the ways of their use in households in the Czech Republic. The main objective is to analyze the use of 3D printing in households. This means to find out why and how often the owners of 3D printers use them in their households. Also, to find out the whole range of other factors related to the ownership of 3D printers such as frequency usage, machine satisfaction, number of owned printers, etc. Based on the analysis for which the data was collected by the questionnaire survey method and later evaluated using hypotheses and comparisons with another similar survey, criteria for 3D printer selection are compiled. These recommendations serve to those who are interested in acquiring this technology. Research conducted in this thesis may be beneficial for future analyzes of this market, or for inventors of 3D printers who are considering to launch their 3D printers on the Czech market.

Voice-enabled applications, applications that interact with a user via an audio channel, are used extensively today. Their use is growing as speech related technologies improve, as speech is one of the most natural methods of interaction. They can provide customer support as IVRs, can be used as an assistive technology, or can become an aural interface to the Internet. Given that the telephone is used extensively throughout the globe, the number of potential users of voice-enabled applications is very high. VoiceXML is a popular, open, high-level, standard means of creating voice-enabled applications which was designed to bring the benefits of web based development to services. While VoiceXML is an ideal language for creating these applications, VoiceXML gateways, the hardware and software responsible for interpreting VoiceXML applications and interfacing with the PSTN, are still expensive and so there is a need for a low-cost gateway. Asterisk, and open-source, TDM/VoIP telephony platform, can be used as a low-cost PSTN interface. This thesis investigates adding a VoiceXML service to Asterisk, creating a low-cost VoiceXML prototype gateway which is able to render voice-enabled applications. Following the Component-Based Software Engineering (CBSE) paradigm, the VoiceXML gateway is divided into a set of components which are sourced from the open-source community, and integrated to create the gateway. The browser requires a VoiceXML interpreter (OpenVXI), a Text-To-Speech engine (Festival) and a speech recognition engine (Sphinx 4). The integration of the components results in a low-cost, open-source VoiceXML gateway. System tests show that the integration of the components was successful, and that the system can handle concurrent calls. A fully compliant version of the gateway can be used in the real world to render voice-enabled applications at a low cost. / KMBT_363 / Adobe Acrobat 9.55 Paper Capture Plug-in

One of the main challenges that modern software developers face is the coordination of dependent agents such as software projects and other developers. Transparent development environments that make low-level software development activities visible hold much promise for assisting developers in making coordination decisions. However, the wealth of information that transparent environments provide is potentially overwhelming when developers are wading through information from potentially millions of developers and millions of software repositories when making decisions around tasks that require coordination with projects or other developers. Overcoming the risk of overload and better assisting developers in these environments requires a principled understanding of what exactly developers need to know about dependencies to make their decisions. My approach to a principled understanding of how developers use information in transparent environments is to model the process using signaling theory as a theoretical lens. Developers making key coordination decisions often must determine qualities about projects and other developers that are not directly observable. Developers infer these unobservable qualities through interpreting information in their environment as signals and use this judgment about the project or developer to inform their decision. In contrast to current software engineering literature which focuses on technical coordination between modules or within projects such as modularity or task assignment mechanisms, this work aims to understand how developers use signals to information coordination decisions with dependencies such as other projects or developers. Through this understanding of the signaling process, I can create improved signals that more accurately represent desired unobservable qualities. My dissertation work examines the qualities and signals that developers use to inform specific coordination tasks through a series of three empirical studies. The specific key coordination tasks studied are evaluating code contributions, discussing problems around contributions, and evaluating projects. My results suggest that when project managers evaluate code contributions, they prefer social signals over technical signals. When project managers discuss contributions, I found that they attend to political signals regarding influence from stakeholders to prioritize which problems need solutions. I found that developers evaluating projects tend to use signals that are related to how the core team works and the potential utility a project provides. In a fourth study, using signaling theory and findings from the qualities and signals that developers use to evaluate projects, I create and evaluate an improved signal called “supportiveness” for community support in projects. I compare this signal against the current signal that developers use, stars count, and find evidence suggesting that my designed signal is more robust and is a stronger indicator of support. The findings of these studies inform the design of tools and environments that assist developers in coordination tasks through suggestions of what signals to show and potentially improving existing signals. My thesis as a whole also suggests opportunities for exploring useful signals for other coordination tasks or even in different transparent environments.

In recent years, a surprising new phenomenon has emerged in which globally-distributed online communities collaborate to create useful and sophisticated computer software. These open source software groups are comprised of generally unaffiliated individuals and organizations who work in a seemingly chaotic fashion and who participate on a voluntary basis without direct financial incentive. The purpose of this research is to investigate the relationship between the social network structure of these intriguing groups and their level of output and activity, where social network structure is defined as 1) closure or connectedness within the group, 2) bridging ties which extend outside of the group, and 3) leader centrality within the group. Based on well-tested theories of social capital and centrality in teams, propositions were formulated which suggest that social network structures associated with successful open source software project communities will exhibit high levels of bridging and moderate levels of closure and leader centrality. The research setting was the SourceForge hosting organization and a study population of 143 project communities was identified. Independent variables included measures of closure and leader centrality defined over conversational ties, along with measures of bridging defined over membership ties. Dependent variables included source code commits and software releases for community output, and software downloads and project site page views for community activity. A cross-sectional study design was used and archival data were extracted and aggregated for the two-year period following the first release of project software. The resulting compiled variables were analyzed using multiple linear and quadratic regressions, controlling for group size and conversational volume. Contrary to theory-based expectations, the surprising results showed that successful project groups exhibited low levels of closure and that the levels of bridging and leader centrality were not important factors of success. These findings suggest that the creation and use of open source software may represent a fundamentally new socio-technical development process which disrupts the team paradigm and which triggers the need for building new theories of collaborative development. These new theories could point towards the broader application of open source methods for the creation of knowledge-based products other than software.
