The purpose of this study was to investigate the possibility of streamlining the test process by utilizing Pair programming. During the process, Pair programming has been practiced as is defined by the Extreme programming (XP) software development methodology, with the other aspects of XP discarded. The focus of the testing itself has been toward unit testing. The methods applied has been with an experimental approach where 93 cases were attempted to be solved by either single programmers or pair programmers. What has been investigated in these experiments was the time needed to complete a case, how many test attempts were needed to solve the case, and how high a percentage of the cases were solved.

The purpose of this study was to investigate the collaboration of four learners of Swedish as a second language during a pair-writing task, as well as their experiences of the process, in order to draw conclusions about how to execute pair-writing in the L2 classroom. The study has found that the establishment of compatible partners are of great importance to achieve success and learning through pair-writing. One of the pairs studied managed to work well together and use each other?s knowledge to improve their text, while the other pair continuosly battled for dominance, which had a negative impact on their performance. The two successful students had enjoyed the task and believed they had learned something from it and that pair-writing can be a useful source of knowledge.

New technological innovations like tablets and smartphones have a taken significant market share on the web and puts new demands on webpages, the user interface and compatibility among different client devices. The full test of a web-based system prior to the publication is often regarded as an important part of the process to create a complete and successful website. This bachelor thesis investigates the possibility to analyze mobile-adapted web sites using a system that first records the visitor's activities and then replays them for an expert analyst to provide valuable information to developers about how their site can be improved.The essay begins with a litterature study on today's most common web development tools and then examines the possibility to apply them during the development of the analysis tool. The work also describes two methods, Pair programming and waterfall method used during the project. Three different evaluation methods are presented and one of the models is applied on the finished system.The project results in a web-based analysis tool written mainly in JavaScript using the jQuery library.

Med en allt mer konkurrensutsatt marknad är det svårt för företagen att nå ut med sina budskap till konsumenterna. Reklam är inget som lockar längre och möjligheterna  att  slippa  dem  blir  bara  fler  och  fler. Ett  relativt  nytt  sätt  att ändå få ut sitt budskap är att förpacka det i redaktionellt material och göra ett TV-  program  av  det  hela,  programming,  det  vill  säga  helt  eller  delvis förfinansierade program..

Många utvecklingsprojekt inom IT misslyckas med att leverera det som efterfrågas. För att lösa detta problem har ett antal utvecklingsmetoder skapats. En av dessa metoder är Extreme Programming. Extreme Programming består av tre delar: värderingar, principer samt praktiker. Syftet med denna studie är att studera vilka problem som kan uppstå när Extreme Programming tillämpas av ett arbetslag om två utvecklare.

Today there is a shortage of skilled IT-technicians in Sweden. It is approximated that Swedish companies can hire 31 000 IT-technicians in 2015 and the need seems to increase in the coming years. One proposed solution to this problem is to make programming more desirable to youths. In this study we attempt to investigate the effects of an introductory course in computer science on youths? (16-17 years old) in a classroom setting.

The increase of complexity in embedded programming is forcing the development of higher level programminglanguages. These languages not only consist of traditional text based programming but also with graphical programminglanguages such as the programming language G from LabVIEW which is developed by National Instruments and havebeen around since the mid eighties. However since 2004 this language has also been able to program embeddedhardware, using the modules LabVIEW SDK and LabVIEW for ARM. This thesis shows how LabVIEW for ARM converts itsgraphical language G to C and then how C is flashed into the microprocessor. The thesis also takes up the pros and consof using G for embedded development.

This thesis presents the work of developing and testing a programming tool specially designed for children. The purpose of this tool is to make children capable of creating visual simulations and games that consist of actors interacting in a virtual world. The name of the programming tool is Behavior Cards, which comes from the fact that actors are programmed by giving them cards representing different kinds of behaviors. Behaviors are to some extent pre-programmed and can include general events specifying how the actors should act in different situations, in contrast to specifying every possible situation that can occur. The idea is that Behavior Cards should be easier to use than a more traditional text based programming tool, but it should also be expressive within the domain of visual games.

This work is done to try to solve a scientific computer problem and its basis derived from the web, as there are a variety of ways to program to it. The most common languages used by developers, both private and corporate are PHP, .NET and Ruby. But why do companies or a private developer choose a specific programming language? Is it because it is better and has more features than the others, or because they are forced? This essay uses a questionnaire and through tests sees which is best and which one is the most popular/used. To illustrate the problem, a survey is conducted and sent to several companies and asked them to answer the questions regarding the issue.

Allt sedan 1960-talet har det utvecklats så många systemutvecklingsmetoder att det kan vara svårt, som systemutvecklare, att välja rätt metod till det utvecklingsprojekt som ska genomföras. För att underlätta valet av systemutvecklingsmetod kan ett jämförelseramverk vara användbart. Detta för att lättare kunna sätta sig in i de utvecklingsmetoder som finns till hands att välja mellan.Denna rapport fokuserar på att jämföra systemutvecklingsmetoden eXtreme Programming med Structured Systems Analysis and Design Method (SSADM) och Rational Unified Process (RUP). Detta görs med hjälp av ett jämförelseramverk. Syftet är att erhålla en djupare kunskap om vad eXtreme Programming är för en typ av systemutvecklingsmetod och vad den har att erbjuda som de mer etablerade metoderna, SSADM och RUP, inte kan erbjuda och vise versa.Resultatet av rapporten är ett jämförelseramverk som kan användas på ett strukturerat sätt för att erhålla information om systemutvecklingsmetoder.

Att sätta sig in i system kan vara krångligt utan rätt sorts dokumentation. Vi har undersökt vilken dokumentation som kan vara lämplig att lämna över till nya utvecklare, som ska arbeta vidare med systemet i software maintenance fasen.Det har gjorts genom att vi har gjort en litteraturstudie om dokumentation samt undersökt vad för dokumentationsartefakter som används när man ska sätta sig in i datorsystem. Vi använde eXtreme Programming för att utveckla ett system som vi försökte dokumentera samtidigt som vi utvecklade det.eXtreme Programming förordar muntlig kommunikation, vilket är svårt att lämna över till nya utvecklare. Vi upptäckte under vår utveckling att det var svårt att föra in dokumentation sam-tidigt som utvecklandet pågick,  därför använde vi bara enhetstester och  strukturerade kod-kommentarer under utvecklingsiterationerna.Vi undersökte hur dokumentationen som skapats fungerade genom att göra en undersökning bestående av strukturerade intervjuer där de fick komma med kommentarer om hur dokumen-tationen hjälpte förståelsen för systemet.Vi lämnar ifrån oss en vidareutveckling  av eXtreme Programming  som innefattar en doku-mentationsiteration  innan överlämnandet  samt en studie om vad för dokumentation som är värdefull att ha vid systemöverlämningar..

With the increase in IT related crimes the IT forensics has more work ahead of them and it is constantly rising. The analysis software called EnCase is widely used by IT forensics all around the globe and with it comes an internal programming language called EnScript.This paper is designed to examine whether a manual for the programming language EnScript can make a difference in how efficiently the work is.A study between two groups has been made and an evaluation of the results between the two groups.The manual provided aims to introduce the reader to EnScript as a programming language and also to provide a solid foundation to build on in further work with EnScript.

To investigate effects of nitrogen on in-lake CO2 and CH4 production during winter, three pair of lakes was subject for a fertilizing experiment in which one lake in each pair was fertilized with nitric acid (HNO3) directly into the water column in the summer of 2012. The lakes in each pair are assumed to be morphologically, hydrologically and biologically similar, that is, the non-fertilized lakes are considered references. The pairs do differ in one major way by being progressively less humic, going from around 25 mg/l to 10 mg/l DOC. Sampling and analysis was carried out at the end of the frozen period in 2013. Results show a significantly higher concentration of both CO2 (p<0,001) and CH4 (?=0,1, p=0,053) between impact and reference sites in the two less humic pairs.
