IENCE C • •S T S E C Small world for dynamic wireless cyber-physical N O H I N systems S O I V Dissertation L • O S 142 G T Y H • R Industries and consumer markets are today increasingly using G I E L VTT SCIEN CE S H E G services exposed from wireless sensor and actuator networks, A I R H C cyber-physical machine-to-machine systems. The motivation for H the research arises from problems detected in the remote 1 4 2 interaction with embedded devices over dynamic wireless networks in such systems. The selected approach is based on the application of the small- world paradigm to cyber-physical systems. It is here assumed that the concept of small world, "six degrees of separation", can be expanded to also cover communication with wireless embedded devices in cyber-physical systems context. The main contributions are the technical enablers referred to as dynamic communication spaces, dynamic M2M service spaces, configuration and remote use of services, communication overlay, access systems selection, integrated mobility, secure ad hoc networking, situated opportunistic communication, hierarchical networking for small-world networks, and short-cuts for network optimization. The enablers have been evaluated as separate technical methods and means by means of experiments and/or simulations. According to the evaluations, the enablers seem to work well as separate building blocks and that they can be combined to expand the concept of small world to also cover communication with embedded devices. Wireless short-cuts can improve the scalability and efficiency of dynamic wireless networking and weak links are essential in the neighbour discovery process. -

Free Email Software Download Best Free Email Client 2021
free email software download Best Free Email Client 2021. This article is all about best free email clients and how they can help you be more productive. We also talk about Clean Email, an easy-to-use email cleaner compatible with virtually all major email services. But before we go over the best email clients for 2021, we believe that we should first explain what advantages email clients have over web-based interfaces of various email services. Clean Email. Take control of your mailbox. What Is an Email Client and Why Should I Use One? If you’re like most people, you probably check your email at least once every day. And if you’re someone whose work involves communication with customers, clients, and coworkers, the chances are that you deal with emails all the time. Even though we spend so much time writing, forwarding, and managing emails, we hardly ever pause for a moment and think about how we could improve our emailing experience. We use clunky web interfaces that are not meant for professional use, we accept outdated applications as if alternatives didn’t exist, and we settle for the default email apps on our mobile devices even though app stores are full of excellent third-party email apps. Broadly speaking, an email client is a computer program used to access and manage a user’s email. But when we use the term email client in this article, we only mean those email clients that can be installed on a desktop computer or a mobile device—not web-based email clients that are hosted remotely and are accessible only from a web browser. -

Communication Between Desktop and Web Applications

Abstract: Nowadays, everybody uses web applications. Despite of their advantages, like being available at any place with Internet, they have some usability problems with regard to common desktop applications. This article tries to analyze the possible solutions in order to interconnect desktop and web applications, centered in the GNOME platform and using RTM-GLib as example and study case.

A general definition of web service said that it is a system which provides an interface to allow interaction between machines over a network. As time passes more and more web applications provide some kind of API in order to access their services. This number is growing and it seems that will keep growing for some time. Some examples of these applications: Flickr, Facebook, Twitter, etc. Web applications has some advantages compared with desktop applications: All the data is shared and in a centralized place. They do not need any special configuration or installation, just a simple web browser is enough. -

Solaris 10 End of Life
Solaris 10 end of life Continue Oracle Solaris 10 has had an amazing OS update, including ground features such as zones (Solaris containers), FSS, Services, Dynamic Tracking (against live production operating systems without impact), and logical domains. These features have been imitated in the market (imitation is the best form of flattery!) like all good things, they have to come to an end. Sun Microsystems was acquired by Oracle and eventually, the largest OS known to the industry, needs to be updated. Oracle has set a retirement date of January 2021. Oracle indicated that Solaris 10 systems would need to raise support costs. Oracle has never provided migratory tools to facilitate migration from Solaris 10 to Solaris 11, so migration to Solaris has been slow. In September 2019, Oracle decided that extended support for Solaris 10 without an additional financial penalty would be delayed until 2024! Well its March 1 is just a reminder that Oracle Solaris 10 is getting the end of life regarding support if you accept extended support from Oracle. Combined with the fact gdpR should take effect on May 25, 2018 you want to make sure that you are either upgraded to Solaris 11.3 or have taken extended support to obtain any patches for security issues.

An User & Developer Perspective on Immutable Oses
An User & Developer Perspective on Dario Faggioli Virtualization SW. Eng. @ SUSE Immutable OSes [email protected] dariof @DarioFaggioli https://dariofaggioli.wordpress.com/ https://about.me/dario.faggioli About Me What I do ● Virtualization Specialist Sw. Eng. @ SUSE since 2018, working on Xen, KVM, QEMU, mostly about performance related stuff ● Daily activities ⇒ how and what for I use my workstation ○ Read and send emails (Evolution, git-send-email, stg mail, ...) ○ Write, build & test code (Xen, KVM, Libvirt, QEMU) ○ Work with the Open Build Service (OBS) ○ Browse Web ○ Test OSes in VMs ○ Meetings / Video calls / Online conferences ○ Chat, work and personal ○ Some 3D Printing ○ Occasionally play games ○ Occasional video-editing ○ Maybe scan / print some document 2 ● Can all of the above be done with an immutable OS ? Immutable OS: What ? Either: ● An OS that you cannot modify Or, at least: ● An OS that you will have an hard time modifying What do you mean “modify” ? ● E.g., installing packages ● ⇒ An OS on which you cannot install packages ● ⇒ An OS on which you will have an hard time installing packages 3 Immutable OS: What ? Seriously? 4 Immutable OS: Why ? Because it will stay clean and hard to break ● Does this sound familiar? ○ Let’s install foo, and it’s dependency, libfoobar_1 ○ Let’s install bar (depends from libfoobar_1, we have it already) ○ Actually, let’s add an external repo. It has libfoobar_2 that makes foo work better! ○ Oh no... libfoobar_2 would break bar!! ● Yeah. It happens. Even in the best families distros -

Performance Testing Suricata The Effect of Configuration Variables On Offline Suricata Performance A Project Completed for CS 6266 Under Jonathon T. Giffin, Assistant Professor, Georgia Institute of Technology by Winston H Messer Project Advisor: Matt Jonkman, President, Open Information Security Foundation December 2011 Messer ii Abstract The Suricata IDS/IPS engine, a viable alternative to Snort, has a multitude of potential configurations. A simplified automated testing system was devised for the purpose of performance testing Suricata in an offline environment. Of the available configuration variables, seventeen were analyzed independently by testing in fifty-six configurations. Of these, three variables were found to have a statistically significant effect on performance: Detect Engine Profile, Multi Pattern Algorithm, and CPU affinity. Acknowledgements In writing the final report on this endeavor, I would like to start by thanking four people who made this project possible: Matt Jonkman, President, Open Information Security Foundation: For allowing me the opportunity to carry out this project under his supervision. Victor Julien, Lead Programmer, Open Information Security Foundation and Anne-Fleur Koolstra, Documentation Specialist, Open Information Security Foundation: For their willingness to share their wisdom and experience of Suricata via email for the past four months.
