Online social networks are reflection human interactions. User share their profile, communicate via messaging and share contents using these online social networks. There are millions of profile available online which contain information about user, their preferences, and their interaction. It posses security threats if it is used by an adversaries. In this paper the authors tried to detect those pattern of information about OSN users and discussed possible threats about their privacy. They have used facebook as a usecase and specifically focus on information from CMU campus. experiments, identification
Information revelation:
Facebook provides default privacy control interface where user could limit his/her personal details from disclosures. However user could control the granular details to establish different degrees of trust and intimacy with others. Some details of revelation of user information are given bellow:
1) Profile search-ability: Strangely enough, a small fraction (1.2%) of user uses privacy setting.
2) Profile visibility: restricting profile access or view to other - only 0.06% of CMU user restricted their profiles to CMU users.
3)Facebook data access: personal facial image and name (first name and last name) are available on facebook to all facebook users which could be used to make dossier about users. Political, sexual preferences, and user credential are available to large fraction of users which could enable some of them to gain control a user profile.
Privacy implications:
The rationale behind large number of user data and sparingly used of privacy preference is that users are unconcerned about their personal privacy. A possible consequence could be high risk to a user or/and his/her associates. These risks are:
1) Stalking:
* user residences and credentials are available online to majority of facebook users. A fraction of facebook user could access those information to actual person and his/her whereabouts. A major profile with AIM and twitter like services (which leads to cyber-stalking) that buddies are added without acknowledgement from them.
* Re-indentification
* Demographic re-identification
* Face re-identification
* Social security numbers and identity theft
* first four digits of SSN + birthday helps in locating the identifying the place where SSN was made.

How to run ns3 in Eclispe
My life became easy ever since I run NS3 from Eclipse. The procedure is easy counter the one described here. You need only two steps:
1) Open New External Configuration, add ${workspace_loc:/ns3dev/waf} (in my case waf is in ~/ns3dev/waf)
2) Specify working directory i.e., ${workspace_loc:/ns3dev/}
3) Open examples/tutorial/first.cc and press external configuration button. Input "first" to dialogue box.
Thats it, :).

The Ninja architecture for robust Internet-scale systems and services
This paper provide provide wide range of services and mechanism for access those mechanism via heterogeneous devices. The services set include: robustness, scalability, distributed Internet services. The architecture assumes the four basic components:
* powerful workstation cluster environments with a software platform that simplifies scalable service construction;
* units, which are the devices by which users access the services;
* active proxies, which are transformational elements that are used for unit- or service-speci®c adaptation;
* and paths, which are an abstraction through which units, services, and active proxies are composed.

Resilient Workload Manager Framework
"In data centers hosting scaling Internet applications, operators face the tradeoff dilemma between resource efficiency and Quality of Service (QoS), and the root cause lies in workload dynamics. In this paper, we address the problem with the design of Resilient Workload Manager (ROM). ROM explicitly segregates base workload and trespassing workload, the two naturally different components in application workload, and manages them separately in two resource zones with specialized optimization techniques.
As a comprehensive workload management framework, ROM covers workload, data, resource, and Quality of Service of the target applications. It features a fast workload factoring algorithm for distributing incoming application requests, not only on volume but also on content, between the two resource zones; integrated two-dimensional workload shaping, resource planning, and request dispatching schemes for efficient utilization of base workload zone resource; and a simple and high-performance system architecture for dynamic provisioning in trespassing workload zone. Through extensive evaluation, we showed ROM can achieve resource efficiency (e.g., 54.9% server saving) guarantee QoS (based on client-side perceived service quality), reduce data access overhead in the trespassing workload zone during peak load (up to two orders of magnitude), and be adaptive at processing speed (running faster at peak load periods than at regular periods)."

Amazon distriburted services
Amazon is one of the largest e-commerce companies which provide different services for various website around the world using its distributed servers. These servers are proven to errors, faults, and failures which necessitates reliability, consistency and flexibility to reconfigure and keep persistent state for the data hosted by those servers. Dynamo, incrementally scalable depend upon the current workloads, provide reliability and availability for major Amazon services. Although versioning and conflict resolutions mechanism are used to provide consistency still it undermines it in some scenarios. From developer point of view, porting and new development a bit more complex because of Dynamo's consistency model and reconciliation logic. Also, it uses Full Membership model where each peers have knowledge of every other peer as for as stored component is concerned. This Full membership model limit scalability because the routing tables are developed by continue gossiping which produce overhead. The problem could be solved by extending it with Distributed DHTs or P2P Systems (which is under consideration of our research).
Location aware DHT
"Place Lab: Device Positioning Using Radio Beacons in the Wild" - is an application API which allows any wireless device to listen to fixed beacon provider for her position estimation. Leveraging this API with Peer could be helpful in making location aware DHTs. Prefix Hash Three (PHT) used Place lab in building location aware DHT. The case study from Sylvia decouples application developed from DHT. A good point to note for while most of applications demand refined and optimized overlay for its QoS and performance requirements.

Information dessimnation in Social Nets
The Java applet shows the self-managed information dessimination in social net with monitoring metrics (at the right). This could be a good idea to implement a online-benchmarking application with user input to determine different quality and performance parameters. Since, information are disseminated in self-configured way, it could be used for monitoring resources, services including security, etc. The interesting question could be how the collect or disseminate information for productive activity.
PageRank, LinkRank, ComRank, WikiFactor, PageFactor, ComFact
PageRank: This is an algorithm which ranks a web-page among set of web-page on WWW by considering a large set of different variables.
LinkRank: is a method of quantifying the modularity of social links in directed network. The original paper assumes modularities in un-directed networks and optimizes it for directed networks.
WikiFactor: "A new metric is introduced, inspired by the Hirsch {\it h-index}, to measure the impact of a wiki site. A table of wikiFactors is presented for a number of wikis, in particular those oriented towards scientific topics. The wikiFactor is defined as the number of web pages, wF, that have had $\ge 1000$wF visits."
Referring to these links one reasonable question would be haw to rank communities, services, privacy settings in sub-graphs or along the whole graph. But what one could buy out of this? Well, considering services provisions and service management, one should provide provide load balancing, some what deterministically routing, or have surgically prune out bad guys (cheaters in MMOG, attackers, or selfish guys).
@ LinkRank: One can predict link, LinkPrdict, by predicting previously un-observed relationship and hence behavior. There are many exciting applications of this particular area of network science. Most research in the area of link prediction has been restricted to scoring based on a single measure within network topologies. While the research considers new measure and placing existing measures in the context of a machine learning task. "We are also casting the problem as a high class imbalance task."

Parallelizing overlay-routing or parallelizing unicast messages for improving FreeNet performance?
How to reduce messages and improve performance? Is it possible to improve by parallelizing a variety of overlay routing? What could be the gain (for MMOG and FreeNet, for instance) over parallel multicast messages?
"that parallelizing a variety of overlay routing algorithms using multi-destination multicasting instead of parallel unicast messages results in significantly reduced message traffic on both edge and internal links. In structured overlays, this message reduction occurs for a variety of operations such as joins, routing table maintenance, and application lookups. In general, latency behavior and operational semantics are retained." Further information about the study could be found at this link.

Darwin: Resource Management for Application-Aware Networks
"Sophisticated multi-party applications will use many traffic streams with very different characteristics and will be network-aware so they can perform well on a variety of networks. At the same time, we see the emergence of an electronic service industry that is eager to deliver a wide variety of services to end-users. Services will range from low-level "bearer" services that transport bit streams over the network infrastructure to value-added services such as video conferencing, computing services, and data mining. Complex applications will support cooperation among multiple parties by combining video conferencing with access to large amounts of archived data, real time data streams, and distributed computing tasks. Supporting this service model and this emerging class of complex services requires innovation in a number of areas, including support for application-specific handling of traffic, sharing of resources between cooperating traffic streams, adapting quickly to changes in the network conditions and application requirements, systematic methods for balancing the constraints and priorities of services competing for network resources, and reliability and security. The CMU application-aware networking project will develop a comprehensive suite of resource management mechanisms in support of such "application-aware" networks. The project is headed by Peter Steenkiste, Allan Fisher, and Hui Zhang."

Social Barometers and other interesting applications to come
Social Signal Processing is a relatively new field with some interesting points of contact on Mobile (PDAs and smart devices) Social Networking. New mobile (PDA and smart devices) devices are equiped with interesting sensors that allow them to record together with the corresponding heuristics social relationships in everyday situations. For this example, gyroscopes, accelerometers, compasses, temperature sensors, etc. Interesting questions like how to use these devices to build social barometers and services that could influence social life more ubiquitely. For further investigations here are two interesting papers.
