Dynamic Allocation of Mail Server Resources Among Users
INTERNATIONAL JOURNAL OF SCIENTIFIC & TECHNOLOGY RESEARCH VOLUME 9, ISSUE 03, MARCH 2020 ISSN 2277-8616 Dynamic Allocation Of Mail Server Resources Among Users Basti M.Aliyeva Index:The article was dedicated to the solution of the problem on the dynamic allocation of mail server resources among users. It was noted that recently the electronic mail system had undergone serious changes and new features have been added to this system. The article examines the working principles of email and defines possible operating modes for subscribers. It was noted that mail server memory should be dynamically allocated among users so that the email can successfully perform its functions. In the article,the linear programming is applied to the problem of dynamic allocation of mail server memory. Known methods at every operation can resolve this issue.Proximity measure has been defined based on the Levenstein Distance (LD) for the determination of the renewal of documents on the server to improve the use of the server resources. This tool can be used to determine whether the documents have changed on the server.In the result, similar documents can be identified, and their number can be reduced up to one. Key Words: email server, dynamic allocation of the memory, operating modes of subscribes, Levenstein Distance (LD), Measures of document proximity. ———————————————————— 1.

Auf Und Ab Groupware
08/2015 Die Entwicklungen bei Linux-Groupware – eine Zwischenbilanz Sysadmin Auf und ab Groupware 58 Der Groupwaremarkt ist ebenso groß wie schwierig: Microsoft Exchange und Lotus Notes halten die dicken Brocken fest, soziale Netzwerke und Google drängen nach. Freie Software kann gleichwohl auf schöne Erfolge verweisen, gerät aber immer wieder in die Opferrolle – meist wegen externer Finanzierung.

Open Ajax" to Drive Collaborative Innovation to Make the Web Easier to Use
TECH TITANS PROPOSE OPEN SOURCE PROJECTS FOR BROWSER-BOOSTING AJAX TECHNOLOGY "Open Ajax" to Drive Collaborative Innovation to Make the Web Easier to Use Armonk, NY, February 1, 2006 . Prominent computer industry vendors and Internet-based businesses today announced that they are making it easier for an open-source community to form and popularize Ajax. Ajax is a fast-growing open client technology that businesses are incorporating into their external and internal Web sites to simplify the browsing experience, and make it easier for users to shop, work, plan, correspond and navigate online. Ajax makes it unnecessary to manually refresh one's browser to send or receive information over the Web. Instead, information is automatically updated and available on demand, allowing you to "drag and drop" or input information and get a response without refreshing the browser, much like you would do on a PC desktop. It can reduce the steps needed to complete a transaction over the Web or create a competitive edge for enterprise companies and Web designers, for example. The initial supporting members of the new initiative -- dubbed Open Ajax -- include BEA, Borland, the Dojo Foundation, Eclipse Foundation, Google, IBM, Laszlo Systems, Mozilla Corporation, Novell, Openwave Systems, Oracle, Red Hat, Yahoo, Zend and Zimbra. They intend to promote Ajax's promise of universal compatibility with any computer device, application, desktop or operating system, and easy incorporation into new and existing software programs. Ajax -- short for Asynchronous JavaScript and XML -- is a type of "Rich Internet Application." It enables Web innovations, including: * The ability to update portions of a Web page without refreshing the entire screen. -

Main Page 1 Main Page FLOSSMETRICS/ OpenTTT guides FLOSS (Free/Libre open source software) is one of the most important trends in IT since the advent of the PC and commodity software, but despite the potential impact on European firms, its adoption is still hampered by limited knowledge, especially among SMEs that could potentially benefit the most from it. This guide (developed in the context of the FLOSSMETRICS and OpenTTT projects) present a set of guidelines and suggestions for the adoption of open source software within SMEs, using a ladder model that will guide companies from the initial selection and adoption of FLOSS within the IT infrastructure up to the creation of suitable business models based on open source software. The guide is split into an introduction to FLOSS and a catalog of open source applications, selected to fulfill the requests that were gathered in the interviews and audit in the OpenTTT project. The application areas are infrastructural software (ranging from network and system management to security), ERP and CRM applications, groupware, document management, content management systems (CMS), VoIP, graphics/CAD/GIS systems, desktop applications, engineering and manufacturing, vertical business applications and eLearning. This is the third edition of the guide; the guide is distributed under a CC-attribution-sharealike 3.0 license. The author is Carlo Daffara ([email protected]).

PETR WEISS SUPERVISOR BRNO 2009 Abstrakt Cieľom práce je vytvoriť software pre podporu webhostingu, čo znamená, vytvoriť systém umožňujúci užívateľom vytváranie si vlastných subdomén v doméne, využívanie emailovej služby, zabezpečenie prístupu k FTP serveru a k databázovému serveru. Obsluha služieb užívateľom musí prebiehať pomocou grafického užívateľského rozhrania podobne, ako aj samotná registrácia do tohto systému. Klúčové slová GNU/Linux, Apache HTTP Server, MySQL Server, PHP: Hypertext Preprocessor, SMTP server, POP3/IMAP Server, FTP Server, webhosting, virtuálni užívatelia Abstract The main goal of this thesis is to create a software tool to support webhosting, it means to create a system that provides email services, services of an FTP server and database server, and allows users to create their own subdomains within the domain. Moreover, the system must provide a graphical interface for its users.

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. -

OSS-Baserade E-Postlösningar En Fallstudie
Institutionen för kommunikation och information Examensarbete i datalogi med inriktning mot nätverks- och systemadministration, 15 HP Grundläggande nivå Vårterminen 2011 OSS-baserade e-postlösningar En fallstudie Viktor Svensson OSS-baserade e-postlösningar Examensrapport inlämnad av Viktor Svensson till Högskolan i Skövde, för Kandidatexamen (B.Sc.) vid Institutionen för kommunikation och information. Arbetet har handletts av Björn Lundell. 2011-06-01 Härmed intygas att allt material i denna rapport, vilket inte är mitt eget, har blivit tydligt identifierat och att inget material är inkluderat som tidigare använts för erhållande av annan examen. Signerat: _______________________________________________ OSS-baserade e-postlösningar Viktor Svensson Sammanfattning Syftet med studien är att analysera möjligheter och begränsningar med att använda programvaror baserade på öppen källkod för att förvalta en organisations e-post där utkontraktering inte är ett alternativ. Detta baseras på tio krav som identifierats som relevanta i relation till e-postlösningar. Inom studiens omfattning representeras OSS (Open Source Software)-lösningarna av programvarorna Zimbra Collaboration Suite, Citadel och Kolab Server. För att undersöka styrkor och svagheter hos dessa har hybridmetoden action case tillämpats. Genom ett interpretativt och iterativt närmande har representanterna ställts inför de identifierade kraven och deras förmåga att leva upp till kraven har analyserats. Undersökningens resultat visar att majoriteten av kraven kan tillgodoses av lösningarna. -
