DIRECTOR's REPORT September 21, 2017
DIRECTOR’S REPORT September 21, 2017 SUMMER PROGRAMMING The 2017 Summer Reading Club (SRC), Read Up! Rise Up! by Design, utilized key aspects of the design thinking methodology in the development of the SRC program curriculum. Design thinking, as it relates to program development, seeks to identify creative solutions to problems by utilizing solution-based strategies. In an ideal setting these creative strategies ultimately result in a constructive resolution to an identified problem or challenge. The design thinking methodology is used in a variety of disciplines i.e. urban planning, web development, education etc. Programming content focused on S.T.R.E.A.M (Science, Technology, Reading, Writing, Engineering, Arts and Math) related subjects. Throughout the summer program participants participated in variety of enrichment activities that promoted creative thinking, problem solving, reading, writing and other forms of creative expression. Summer Reading Club registration began May 15th, 2017 with the contest and associated programming continuing for 9 weeks (June 5th – August 5th). 10,156 students registered for this year’s SRC with 5,286 participants completing. The 2017 completion rate continued its upward trend with 52% of all participants completing the program. The Cleveland Public Library received generous financial and in-kind support from the Friends of the Cleveland Public Library Foundation, The Cleveland Museum of Art, The City of Cleveland, Cleveland Fire Department, Cleveland Metropolitan School District, United Way of Greater Cleveland, Greater Cleveland Food Bank, KPMG, Mitchell’s Ice Cream, McDonalds, and Georgio’s Pizza. The Library was also the recipient of multiple book grants that enabled children to receive free books for participating in the program. -
A Framework for Real-Time Communications
Anton is a leading experts on Real Time Anton Venema Communications solutions, and the 1 Chief Technology Officer visionary lead architect behind IceLink, WebSync and LiveSwitch. iRTC Internet-Based Real Time Communications Introduction What’s the first thought that comes into your mind when you think about real-time communications? Is it a phone call you had a few minutes ago? A text message sent to your mobile? Maybe something more modern, like a tweet or video broadcast? All of these fall under the umbrella of what we like to call Internet-based real time communications, or iRTC for short. Real-time communications have been a part of our lives for a long time. From public telephone networks to radios all the way back to the telegraph, humanity has a history of seeking out new and better ways to use technology to improve communication. In the past decade, technology has arguably advanced more than the past century before it. Smartphones have stormed the market, mobile processors are advancing in line with Moore’s law, LTE rollouts are delivering unprecedented Internet speeds across the world, and WiFi hotspots are becoming ubiquitous. iRTC Includes Many Applications The availability of high-speed Internet services just about everywhere is causing a fundamental shift in the way people want to communicate and consume media. Cable networks are finding it more difficult to distinguish between their Internet and TV services, especially when companies like Netflix and HBO are able to publish their content directly to consumers over the Internet. Even live broadcasts, TV’s last stronghold, are being slowly replaced as platforms like YouTube allow content to be broadcast live to millions of users simultaneously over the Internet. -

Webrtc About
WebRTC About WebRTC provides Real-Time Communications directly from better web browsers and devices without requiring plug-ins such as Adobe Flash nor Silverlight. WebRTC always operates in secure mode.FreeSWITCH provides a WebRTC portal to its public conference bridge to demonstrate the possibilities for handling telephony via a web page; join us for our weekly conference calls. The process for configuring FreeSWITCH with WSS certificates is the same whether for use with classic WebRTC or the FreeSWITCH Verto endpoint. Installation The configuration for Secure Web Sockets is slightly different than for TLS over SIP. This guide covers WSS certificate setup. Debian 7 (Wheezy) Install Debian 7 (Wheezy) minimal.

Concurrent Programming Made Simple: the (R)Evolution of Transactional Memory
Concurrent Programming Made Simple: The (r)evolution of Transactional Memory Nuno Diegues∗1 and Torvald Riegely2 1INESC-ID, Lisbon, Portugal 2Red Hat October 1, 2013 ∗[email protected] [email protected] 1 1 Harnessing Concurrency Today, it is commonplace for developers to deal with concurrency in their applications. This reality has been driven by two ongoing revolutions in terms of hardware deployments. On one hand, processors have evolved to a multi- core paradigm in which computational power increases by increasing number of cores rather than by enhancing single thread performance. On the other hand, cloud computing has democratized the access to affordable large- scale distributed platforms. In both cases programmers are faced with a similar problem: if they want to scale out their applications, then they need to tackle the issue of how to synchronize access to data in face of ever growing concurrency levels. For many decades, programmers have been taught to rely on locking mechanisms or centralized components to manage concurrent accesses to data. However, the ongoing architectural trends towards massively parallel/large- scale systems have unveiled the limitations of traditional synchronization schemes — not only can they significantly limit the feasible parallelism, when there may exist tremendous untapped parallel potential; they also force to use intricate programming models that are prone to tricky concurrency bugs, which can be a conundrum to detect and fix. In fact, popular knowledge considers locking approaches simple to understand, but difficult to master. 2 Programming with Transactions To tackle this fundamental problem in modern software development, during recent years both industry and academia have started to adopt Transactional Memory (TM). -

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. The Session Initiation Protocol (SIP) is a multimedia signalling protocol that has evolved into a widely adopted communication standard. The integration of SIP into existing IP networks has fostered IP networks becoming a convergence platform for both real- time and non-real-time multimedia communications. This converged platform integrates data, voice, video, presence, messaging, and conference services into a single network that offers new communication experiences for users. The open source community has contributed to SIP adoption through the development of open source software for both SIP clients and servers. In this paper, we provide a survey on open SIP systems that can be built using publically available software. We identify SIP features for service deve- lopment and programming, services and applications of a SIP-converged platform, and the most important technologies support- ing SIP functionalities. We propose an advanced converged IP communication platform that uses SIP for service delivery.
