Since the speedy popularity of Internet infrastructure and explosive increasing of World Wide Web services, a lot of traditional companies had web-enabled their business over Internet and used WWW as their application platform. Those web services, such as the on-line search, e-learning, e-commence, multimedia, network service, e-government etc., need a stable and powerful web server to support the huge capability. The web hosting service becomes increasingly important in which the service providers offer system resources to store and to provide Web access to contents from individuals, institutions, and companies, who lack resources or expertise to maintain their Web site. Web server cluster is a popular architecture used by the hosting service providers as a way to create scalable and highly available solutions. However, hosting a variety of contents from different customers on such a distributed server system faces new design and management problems. This dissertation describes the work pursuing for constructing a system to address the challenges of hosting Web content on a server cluster environment. Based on the achievement of the software-based content-aware distributor, some high repetition and fixity tasks originally treated by software module are delivered to hardware module for speeding up the packet processes and for sharing the loads on the software module. Our software-based distributor is implemented in Linux kernel as a loadable module. A few system calls in user level are built to support the integration of resource management.

Στα πλαίσια αυτής της εργασίας έγινε μια απόπειρα καταγραφής και μελέτης των δυνατοτήτων που παρέχονται σήμερα για την ανάπτυξη δικτυακών εφαρμογών σε περιβάλλον Java με χρήση της τεχνολογίας Ajax. Στα πρώτα τρία κεφάλαια γίνεται μια συνοπτική αναφορά σε κάποιες κεντρικές έννοιες και εργαλεία ανάπτυξης Web εφαρμογών σε περιβάλλον Java πρίν την εμφάνιση του Ajax, όπως η γλώσσα HTML, η γλώσσα Javascript, και οι τεχνολογίες που ανέπτυξε η εταιρία Sun για αυτό το σκοπό. Επίσης περιγράφονται κάποια δημοφιλή αυτόνομα εργαλεία ανάπτυξης που στηρίχθηκαν στις παραπάνω τεχνολογίες και τις επέκτειναν. Το αντικείμενο του κεφαλαίου 4 είναι η τεχνολογία Ajax και ο βασικός μηχανισμός πίσω από αυτήν, δηλαδή το αντικείμενο XHR της Javascript. Στο κεφάλαιο 5 γίνεται λόγος για τα frameworks που είναι διαθέσιμα σήμερα και παρέχουν ενσωμάτωση της νέας τεχνολογίας σε εφαρμογές Java, και εισάγεται ένας βασικός διαχωρισμός ανάμεσα στα Direct Ajax Frameworks και στα Indirect Ajax Frameworks. Αυτός ο διαχωρισμός αφορά κυριώς διαφορετικές προσεγγίσεις σε θέματα ανάπτυξης και συνεργασίας με άλλες τεχνολογίες, και γίνεται πιο σαφής στα κεφάλαια 6 και 7. Στο κεφάλαιο 6 περιγράφεται η κατηγορία των Direct Ajax Frameworks, τα κοινά χαρακτηριστικά τους, οι τρόποι χρήσης τους και παρατίθενται λεπτομέρειες για κάποια από τα δημοφιλή frameworks της κατηγορίας. Στο κεφάλαιο 7 περιέχονται αντίστοιχα στοιχεία για την κατηγορία των Indirect Java Ajax Frameworks. Το κεφάλαιο 8 αφορά την υλοποίηση που έγινε στα πλαίσια της εργασίας. Το αντικείμενο της ήταν η προσθήκη στοιχείων της τεχνολογίας Ajax σε μια ήδη υπάρχουσα Java Web εφαρμογή χρησιμοποιώντας δυο διαφορετικά δημοφιλή Ajax Frameworks. Στόχος της υλοποίησης ήταν να γίνει μια εκτίμηση της ευκολία χρήσης, για κάθε ένα από τα δυο frameworks, και της ποιότητας του αποτελέσματος. Τέλος, στο κεφάλαιο 9 συνοψίζονται τα χαρακτηριστικά, τα πλεονεκτήματα και τα μειονεκτήματα των Frameworks που περιγράφηκαν, και αποτυπώνονται κάποια συνολικά συμπεράσματα για τους τρόπους χρήσης της τεχνολογίας και τις δυνατότητες που αυτή παρέχει. / -

Thesis (MPhil)--Stellenbosch University, 2004. / ENGLISH ABSTRACT: The Ministry of Information of Eritrea is basically aimed at providing the society with news, information, education and entertainment. In addition to its service presentation through radio, TV and printed press the Ministry of Information has taken the initiative to present its services in the digital way by publishing a website known as shabait.com. But as the technique is new to the country as well as to the organization, it is to be expected that there will be inaccuracies in the way the website was designed. Hence, evaluating and redesigning shabait.com with the goal of making it informative, attractive and easy to use will be very beneficial to the organization as well as to users of the website. This recently launched website is not very attractive and not successfully directed to its users. Therefore, the main aim of this study is to assess and find the best way of presenting information digitally to the Eritrean society, as well as to anyone interested in finding out about Eritrea through the State owned media website. This study was firstly approached by gathering previously written relevant information from books, journals, and the Internet. In addition to that interviews with concerned people in Eritrea were held to understand the aim, difficulties and challenges of the website. Subsequently the website was assessed according to the evaluation criteria developed, based on the literature review. The evaluation of the website assumed three different approaches of qualitative as well as quantitative types. A usability test with both quantitative and qualitative questions was done through a questionnaire, which was analyzed statistically. A competitive analysis, of qualitative type with two international websites was also made. In order to create a good quality website, it is essential to have clearly specified goals, policies and strategies, and adequate advanced human as well as technological resources, so that it will be easy to overcome the common challenges such as competition, diversity of users, budget constraints, and inadequacy of policy instruments. The findings of the evaluation of shabait.com indicate that the website is not attractive, is user unfriendly, of low content quality as well as with low download speed and, more importantly, was not advertised well. Therefore, shabait.com is not fit to be considered as a sole first hand information provider website for the Eritrean society as well as for anybody who is concerned about Eritrea. At the end of the study recommendations of how the website can be modified to be successful are listed. / AFRIKAANSE OPSOMMING: Die doelwit van die Ministerie van Inligting van Eritrea is om nuus, inligting, opvoeding en vermaak aan die gemeenskap te verskaf. Bykomend tot die radio, TV en die gedrukte media, het die Ministerie van Inligting nou ook besluit om 'n digitale diens te lewer deur middel van 'n webwerf bekend as shabait.com. Aangesien die betrokke tegnieke vir die land sowel as vir die organisasie iets nuuts is, kan daar verwag word dat die ontwerp van die webwerf onakkuraathede sal toon. Dus moet shabait.com evalueer en verbeter word om dit sodoende aantreklik en gebruikersvriendelik te maak; dit sal tot die voordeel strek van die organisasie so wel as die gebruikers. Hierdie jong webwerf is tans nie baie aantreklik of maklik om te gebruik nie. Dus is die doelwit van hierdie studie om die beste wyses te vind om die gemeenskap van Eritrea, sowel as ander belangstellendes, deur middel van 'n webwerf wat deur die staat beheer word, digitaal van inligting te bedien. Relevante geskrewe inligting is bekom deur middel van boeke, joernale en die Internet. Daar is ook onderhoude gevoer met mense betrokke by shabait.com om sodoende die doelwitte, probleme en uitdagings van die webwerf beter te verstaan. Daarna is die webwerf evalueer volgens ontwikkelde kriteria gebaseer op die literatuuroorsig. Vir die evaluasie is drie benaderings gebruik, beide kwalitatief en kwantitatief. 'n Bruikbaarheidstoets is deur middel van 'n vraelys gedoen met kwalitatiewe sowel as kwantitatiewe vrae en die antwoorde is statisties ontleed. Twee internasionale webwerwe is ook ontleed sodat hulle gehalte met dié van shabait.com vergelyk kon word. Om 'n webwerf van goeie gehalte te ontwerp, is dit noodsaaklik om duidelik omskrewe doelwitte, beleide en stategië, asook genoegsaam opgeleide mense en gevorderde tegnologiese hulpbronne te hê sodat die uitdagings soos kompetisie, verskeidenheid van gebruikers, begrotingsbeperkings en swak beleidsinstrumente oorkom kan word. Die bevindinge van die evaluasie van shabait.com toon dat die webwerf onaantreklik en gebruikersonvriendelik is, die inhoud is van swak gehalte, die aflaai spoed is laag en en die werf is nie goed adverteer nie. Daarom is die werf nie geskik om beskou te word as die enigste eerstehandse inligtingsverskaffer webwerf vir die gemeenskap van Eritrea sowel as ander belangstellendes nie. Aan die einde van die studie is daar aanbevelings vir die verbetering van die webwerf.

Self presentation is evolving; with digital technologies, with the Web and personal publishing, and then with mainstream adoption of online social media. Where are we going next? One possibility is towards a world where we log and own vast amounts of data about ourselves. We choose to share - or not - the data as part of our identity, and in interactions with others; it contributes to our day-to-day personhood or sense of self. I imagine a world where the individual is empowered by their digital traces (not imprisoned), but this is a complex world. This thesis examines the many factors at play when we present ourselves through Web technologies. I optimistically look to a future where control over our digital identities are not in the hands of centralised actors, but our own, and both survey and contribute to the ongoing technical work which strives to make this a reality. Decentralisation changes things in unexpected ways. In the context of the bigger picture of our online selves, building on what we already know about self-presentation from decades of Social Science research, I examine what might change as we move towards decentralisation; how people could be affected, and what the possibilities are for a positive change. Finally I explore one possible way of self-presentation on a decentralised social Web through lightweight controls which allow an audience to set their expectations in order for the subject to meet them appropriately. I seek to acknowledge the multifaceted, complicated, messy, socially-shaped nature of the self in a way that makes sense to software developers. Technology may always fall short when dealing with humanness, but the framework outlined in this thesis can provide a foundation for more easily considering all of the factors surrounding individual self-presentation in order to build future systems which empower participants.

This thesis is examining the best known internet service -- WWW, it's history and current trends. Following part deals conception of Web 2.0, which is currently subject of intensive discussions it's supporters and opponents. Theoretical knowledge is than applied in analysis of services of new developed web portal koli.cz, which I personally consider the goal of thesis. There are mentioned both of particular sections of web-portal and their interconnection within the whole system. In connection with practical part of thesis are described the most important web portals in world's and Czech Republic's internet market and their biggest source of income, internet advertisement. Own contribution of this thesis is mainly in it's practical part, which is intended to be applied for following analysis and development of koli.cz.
