The NO SPIN, Take Your "Secrets" and Shove 'Em Marketing Strategies For Photographers

The world is trending in real time! Learn from Twitter to scalably process tweets, or any big data stream, in real-time to drive d3 visualizations using Apache Storm, the “Hadoop of Real Time.” Storm is free, open source, and fun to use! Learn from Karthik Ramasamy, Technical Lead of Storm@Twitter, about the distributed, fault-tolerant, and flexible technology used to power Twitter’s real-time data flow pipeline. Twitter open sourced Storm in 2011, and it graduated to a top-level Apache project in September, 2014. Starting from basic distributed concepts presented during our first Udacity-Twitter Storm Hackathon, link Storm concepts to Storm syntax to scalably drive Word Cloud visualizations with Vagrant, Ubuntu, Maven, Flask, Redis, and d3. Link to the public Twitter gardenhose stream to process live tweets, parse embedded URLs, and calculate Top worldwide hashtags. Extend beyond Storm basics by exploring multi-language capabilities in Python, integrate open source components, and implement real-time streaming joins. In your final project, follow real-time trending topics by implementing the data pipeline to visualize only tweets that contain Top worldwide hashtags. Extend your project by exploring the Twitter API, or any data source, alongside Hackathon participants as they design their own ideas, receive feedback from Karthik, and open source a final project calculating real-time tweet sentiment and geolocation to drive a U.S. Map.

The increased demand by consumers and businesses for more utility, connectivity and smarter and more efficient electronic technology not only creates a need for more embedded systems but also for engineers in the embedded systems field.

In this lab-based computer science course, explore the complexities of embedded systems and learn how to develop your own real-time operating system (RTOS) by building a personal fitness device with Bluetooth connectivity (BLE). An operating system (OS) is a software system that computers use to manage the resources of a computer. The OS decides which tasks are performed when and decides how resources are utilized. Simple embedded systems, which are a combination of electrical, mechanical, chemical, and computer components designed to perform a dedicated function, originally did not need an OS. However, as embedded systems have evolved, so have their complexities. To manage this, an RTOS is now required.

Embedded systems are often deployed in safety-critical situations such as automotive, military, industrial, and medical applications. In applications such as communications and consumer electronics, response time and processing speed are important. A real-time system not only needs to arrive at the correct answer, but must also get the correct answer at the correct time. A RTOS manages a computer's resources so that tasks are performed in a timely mannner.

In this computer science course, students will learn the design fundamentals of an RTOS from the bottom up and use these fundamentals to build practical real-time applications. We will provide a board support package (BSP), so students will be able to focus on the RTOS and Bluetooth network without needing prior experience in circuits and I/O device driver software. This is a hands-on project-based lab course, where you will incrementally build a personal fitness device with Bluetooth connectivity.

This course is intended for students and professional engineers wishing to improve their skills in the fields of embedded systems, product development, computer architecture, operating systems, and Bluetooth networks.

To complete this course, you will need to purchase a lab kit including a microcontroller board, an I/O board, and a Bluetooth module. Instructions about purchasing the kit and installing required software are at http://edx-org-utaustinx.s3.amazonaws.com/UT601x/RTOS.html .

Curso de iniciación a RealFlow.

Las economías latinoamericanas han padecido en forma generalizada la falta de crecimiento, así como una gran inestabilidad macroeconómica. Es poco lo que se ha ganado en productividad y ha habido numerosos episodios de recesiones profundas, crisis bancarias, inflación desbordada y escasez de divisas. Todos estos factores afectan la calidad de vida en América Latina. En realidad, solo con mayores niveles de crecimiento sostenido a través del tiempo, es posible pensar que América Latina supere la pobreza y mejore el nivel de vida de la región.

Este curso analiza los principales desafíos que la región enfrenta en cuanto a su crecimiento económico y estabilidad macroeconómica. Los contenidos serán presentados en un lenguaje simple y comprensible para no especialistas en el tema.

Este curso pretende abordar las siguientes preguntas:

• ¿Cuáles son los desafíos que enfrentan los países en América Latina y el Caribe para incrementar sus niveles de inversión privada?
• ¿Por qué la productividad en la región es más baja comparada con la de otras regiones?
• ¿Cuáles son los principales desafíos que enfrenta la infraestructura, sea esta la relacionada con agua y saneamiento básico, el transporte o la energía, para mencionar algunos sectores?
• ¿Por qué los recursos naturales, que abundan en la región, no siempre han dado los resultados esperados para propiciar el desarrollo regional?
• ¿Cómo se origina la inestabilidad económica y las crisis macroeconómicas?
• ¿Cuál es el rol de las políticas monetarias, cambiarias y financieras para alcanzar estabilidad macroeconómica?

La preparación de este curso fue financiada por el Programa Especial para el Desarrollo Institucional (SPID) del Banco Interamericano de Desarrollo. Mayor información en la página web del SPID.

¿Cuáles son los avances y desafíos que América Latina y el Caribe tiene por delante en relación a la pobreza y desigualdad, desarrollo infantil temprano, educación, salud, protección social y empleo?

En este MOOC conocerás el panorama actual de cada uno de estos aspectos en la región, así como políticas basadas en evidencia y casos prácticos de programas sociales que han resultado efectivos en la mejora de la calidad de vida de los habitantes de la región.

Si te interesa el desarrollo económico y social de América Latina y el Caribe y quieres conocer cómo abordar estos desafíos con información actualizada y un lenguaje sencillo, regístrate en el curso y únete a nuestra comunidad de alumnos.

In this course we will study Plato's ancient art of blowing up your beliefs as you go, to make sure they're built to last. We spend six weeks studying three Platonic dialogues, then two more weeks pondering a pair of footnotes to Plato; that is, we will consider some contemporary manifestations of issues Plato discusses. Our focus will be: moral theory and moral psychology.

To provide instruction and dialog on practical ethical issues relating to the responsible conduct of human and animal research in the brain and cognitive sciences. Specific emphasis will be placed on topics relevant to young researchers including data handling, animal and human subjects, misconduct, mentoring, intellectual property, and publication.
