This ebook constitutes the completely refereed post-conference complaints of the seventh foreign convention on Bio-Inspired versions of community, info and Computing platforms (Bionetics 2012), held in Lugano, Switzerland, in December 2012. The 23 revised complete papers offered have been rigorously reviewed and chosen from forty submissions. They conceal issues akin to networking, robotics and neural networks, molecular scale and bioinformatics, optimization and bio-inspired modeling in a variety of fields.

Mastering Rails software deployment
This ebook will express you from begin to end how to:
Setup a VPS from Scratch
Setup extra servers in mins
Use Capistrano three to set up speedy and reliably
Automate uninteresting upkeep tasks
If you've acquired functions on Heroku that are costing you a fortune, it will offer you the instruments you want to stream them onto a VPS. This contains working numerous Rails purposes on a unmarried VPS - nice for small part projects.
If you're already operating your app on a VPS however the install procedure is flaky - it occasionally doesn't restart or lots the inaccurate model of the code - this publication presents a template for making the method difficulty free.
Section 1: Chef
How to automate provisioning new servers with chef. by means of the top you'll be capable to get a brand new server up and able to use inside of minutes.
Many ordinary Rails procedure configurations are supported out of the field with the instance code (MySQL, PostgreSQL, MongoDB and Redis). For anything, exact directions for developing your personal customized configurations are supplied.
The goal of this part is to construct a re-usable blueprint you should use everytime you have to setup a brand new VPS.
Section 2: Capistrano 3
Using Capistrano three to automate each element of deployment, from updating code to dealing with resources and historical past workers.
Particular recognition is paid to constructing 0 downtime deployment - crucial if you're iterating speedily and wish to install a number of instances in line with day. This incorporates a part on universal gotchas reminiscent of failing to reload the gemfile on deployment in addition to a close consultant to troubleshooting while it is going wrong.
I've spent 1000's of hours combing via web publication posts, documentation and tweaking config records. This has bought me to the degree the place deploying to a VPS is as effortless as - in reality frequently more straightforward than - deploying to Heroku. in order to do an analogous, this e-book will prevent loads of time.
Current final touch & Feedback
The first part - provisioning a server with chef - is whole, together with directions for PostgreSQL, MySQL and MongoDB. This incorporates a "Five minute VPS" quickstart part for the impatient.
The moment part - deploying with Capistrano three - can also be to be had and contains the entire details had to get 0 downtime deployments operating with Rails 3/4 and Unicorn. in addition to targeted pattern code, it comprises whole directions for deploying Sidekiq staff, an in depth part on Configuring 0 Downtime deployment and directions for configuring NGinx Virtualhosts and SSL
Over the following couple of months I'll be including extra chapters which cross into aspect on backups and database administration in addition to modifying the e-book in keeping with the suggestions I've got to this point (please retain this coming! ). I'll additionally proceed so as to add additional chapters as and whilst I encounter new suggestions and tricks.
Any suggestions on content material, constitution or corrections very gratefully got, you will get me on twitter (@talkingquickly) or utilizing the leanpub talk about button below.
Android is the preferred cellular telephone working approach at
present, with over one million purposes. on a daily basis hundreds of thousands of
applications are released to the PlayStore, which clients from all
over the realm obtain and use. frequently, those purposes have
serious safeguard weaknesses in them, that may lead an attacker
to make the most the applying and get entry to sensitive
information. this can be the place penetration trying out comes into play to
check for varied vulnerabilities
Learning Pentesting for Android is a pragmatic and hands-on
guide to take you from the very simple point of Android Security
gradually to pentesting and auditing Android. it really is a
step-by-step consultant, overlaying a number of thoughts and
methodologies so that you can examine and use as a way to practice real
life penetration trying out on Android units and functions. The
book starts off with the fundamentals of Android protection and the
permission version, which we are going to pass utilizing a custom
application, written through us. Thereafter we are going to stream to the
internals of Android purposes from a safety aspect of view
and will opposite and audit them to discover the protection weaknesses
using guide research in addition to utilizing computerized tools
We will then circulation to a dynamic research of Android applications
where we are going to find out how to trap and research community site visitors on
Android units and extract delicate info and records from
a packet seize from an Android gadget. we'll inspect SQLite
databases, and learn how to locate and take advantage of the injection
vulnerabilities. additionally, we'll look at root exploits, and how
to take advantage of units to get complete entry in addition to a reverse
connect shell. eventually, we are going to how you can write a penetration
testing file for an Android software auditing project
Das Arbeitsbuch Wirtschaftsinformatik bildet eine Lernhilfe zu dem bewährten Lehrbuch 'Einführung in die Wirtschaftsinformatik' derselben Autoren. Es hat das Ziel, den Lehrstoff stärker zu veranschaulichen und zu vertiefen, um so die Prüfungsvorbereitung im Fach Wirtschaftsinformatik wirksam zu unterstützen.
Risikomanagement ist ein Schlüsselwerkzeug für Führungskräfte im Projekt und in der Linie. Es hilft dabei, Chancen, Unsicherheiten und Gefahren bewusst und proaktiv anzupacken, und damit kritische Probleme zu vermeiden. Sein pragmatischer Einsatz ist heute überlebensnotwendig und aufgrund von wachsenden Anforderungen an Produkthaftung und Governance für die Unternehmensführung verpflichtend.

In the second stage, we use the Expectation Maximization (EM) algorithm to estimate the parameters of the mixture model. The EM algorithm provides an eﬃcient iterative procedure to compute the Maximum Likelihood (ML) estimates in the presence of missing or unobservable data. It iterates two steps: in the expectation step (E-step) the distribution of the unobservable variable is estimated and in the maximization step (M-step) the parameters which maximize the expected log likelihood found on the E-step are calculated.
Basing on the Swarm Intelligence paradigm and its derivative, the Ant Colony Optimization scheme , there were various ant routing algorithms proposed for both ﬁxed and wireless telecommunication networks. The ﬁrst ant routing algorithm designed for asymmetric packet-switched networks was introduced by Dorigo and di Caro . Their AntNet algorithm implicitly achieves load balancing by employing a probabilistic distribution of packets on multiple paths. The experiments reported in [7–9] proved that AntNet outperforms other competitors, such as Q-routing , PQrouting , Shortest Path First (SPF) and OSPF , in terms of the throughput and the delay.
9, 286–294 (1982) 14. The network simulator ns-2. pl NASK Research and Academic Computer Network, 02-796 Warsaw, Poland Abstract. This paper introduces the Reactive ASR-FA algorithm which is a novel ant routing algorithm that utilizes statistical models of packet delay to detect changes in the network conditions. The algorithm is able to quickly react to various load level changes by temporarily modifying the learning parameter’s settings. We show in a set of experiments that using the Reactive ASR-FA signiﬁcantly speeds up the adaptation process of ant routing algorithms and assures lower values of the mean packet delay.
