Know your platform. 7 things every scala developer should know about jvmPawel Szulc
Your Scala code can be cohesive, beautiful and fully functional. But at the end of the day, it runs on the JVM - powerful platform which also has its limits.
Is this fact fully transparent to a Scala developer or does basic understanding of the platform can be beneficial? Can we squeeze full potential out of our code? Are we aware of limits of our runtime environment? This talk will try to answer those questions.
we will show how Scala code is transformed to bytecode and what that implies
we will try to answer the question why @tailrec matters
we will look at the organization of the JVM memory
we will understand how different GC algorithms work
we will see if different GC algorithm can change performance of our code
we will look at toolkits located at JAVA_HOME/bin/
we will try to scratch a surface of JIT :)
This is basic introduction to the topic. We will not show you how compiler works internally :) But we will try to give you general overview of internals of the platform that you use on a daily basis.

In 2009, when worked for the Region of Peel government, Canada, we successfully used patent mapping to identify US patent intensive companies as the potential employers for highly educated immigrants. Following this initiative, we have created and been maintaining a Canadian patent competitive intelligence (CI) database to track the latest patent competence of over 2800 Canadian entities on a weekly basis. This database provides intelligence for long-term strategic research planning and short-term tactics.
This is a due diligence directory of Canadian US patents holders. It has the latest information about who has US patents in Canada, where the US patent holders are, what they patented in the US market and the trends of their US patents.
In 2009, when I was working for the Region of Peel government, Canada, I successfully used patent mapping to identify 20 US patent intensive companies as the potential employers for highly educated immigrants. Following this initiative, I created a Canadian patent competitive intelligence (CI) database to track the latest patent competence of Canadian entities, in all sector throughout Canada, on a weekly basis. There has been the information of 6,000+ Canadian companies in this information repository now. My work with Region of Peel from 2010 to 2012 showed that this database can provide the "no-older-than-7-day" intelligence for long-term strategic research/planning and short-term tactics. This is also the first attempt in Canada to use patent landscape as a regional economic strength indicator and a baseline for policy harmonization and policy performance evaluation.

The successful provision of energy services depends on the creation of resilient and reliable energy projects. Their resilience depends on the whole system’s ability to handle shocks and stresses, such as natural hazards and the effects of climate change. Meanwhile, the reliability of schemes depends on the on-going relationship between communities and technology. This can, in turn, contribute to broader community resilience. This webinar explores these interlinkages in the context of Nepal, and is being held jointly with HPNet - the Hydro Empowerment Network (www.hpnet.org)

Minigrids. They're one of the most attractive models for remote community electrification. They're scalable, and flexible, and capable of supplying power at levels that really permit productive use to be made of the power. But at the same time, they raise alot of questions - what is the most appropriate structure, size, payment system etc for a particular local community. Getting these things wrong has led to systems failing, or not having the development impact they were intended to have.
To try to address some of these issues, Energy Action Partners have devised their Minigrid Game. This is a collaborative role-playing game built around a representation of a minigrid system, intended to be used as an educational and collaborative planning tool in designing a community-sized minigrid system. The game is designed to be used within a process that explores minigrid planning and operational decisions.
The Minigrid Game is a completely novel way for communities to develop workable solutions to the unique challenges of managing a community minigrid, such as system sizing, tariff-setting, and demand-side management. By playing as a group, the players can also improve their understanding of energy technology, practice negotiation and consensus-building skills, and most importantly, have fun.
Join us on Tuesday 15th to hear more about the game and its applications from Scott Kennedy, Executive Director and Ayu Abdullah, Southeast Asia Director of Enact Partners, and also for an opportunity for all partipants worldwide to play the game live during the webinar!
WEBINAR | ENERGY AND TRANSPORT | Sustainable Transportation Infrastructure in...Smart Villages
Smart Villages/LCEDN webinar series

https://e4sv.org/events/webinar-energy-and-transport
Transport is an often overlooked aspect of rural development and linkage to energy access and productive use of energy in the developing world, but it is of critical importance. Not only does transportation rely on a source of energy (and hence transport can itself become a productive use of energy), but an effective transport infrastructure is a critical part of allowing mobility, access to markets, establishment of distribution chains (both to access energy generating equipment as well as marketing services, goods and products).
In this webinar, we were joined by experts presenting on diverse aspects of this complex challenge, including Prof Gina Porter and Dr Arash Azizi of the University of Durham, Dipak Gyawali, former Minister of Water Resources in Nepal and Chair of the Nepal Water Conservation Foundation, and Dr Ben Campbell from the UK Low Carbon Energy Development Network. As usual, we provided an opportunity for the participants joining the webinar to put questions to the speakers, for them to be answered during the session.

For more information, please go to e4sv.org
https://e4sv.org/events/webinar-education-and-young-people
One of the most powerful benefits of energy access in rural communities in the developing world is the potential impact on education. Whether a simple solar lantern permits an extra hour of homework and study after dark, or whether a more sophisticated community energy and ICT project permits remote education and training to take place. And one of the most important, but often under-represented, groups of community stakeholders are young people.
This LCEDN/Smart Villages webinar aims to create a wide-ranging discussion on these issues, with experts presenting their experiences and work on diverse aspects of the energy/youth/education equation.
Our presenters this month include Dr Jiska de Groot and the team at the Energy Research Centre at the University of Cape Town, Craig Gibbs from JET Education Services in South Africa, Prof Jo Tacchi and Dr Amalia Sabiescu from Loughborough University, and Rachita Misra and Huda Jaffer from the SELCO Foundation.
In addition to presentations on their experiences, the webinar included an opportunity for Q&A with all webinar participants.

If you are a start-up or a smaller energy access firm looking to raise funds, then energy-targeted crowdfunding may just be for you.
Raising the necessary finance for start-up and scale-up energy access ventures on terms that make commercial sense is one of the biggest challenges in the sector. In the search for appropriate finance, innovative energy access projects are increasingly turning to crowdfunding to address their financing need.
Energy4Impact has spent the last 3 years looking into the challenges and opportunities in crowdfunding energy access. In this webinar, they will share some of their findings and recommendations, covering donation, reward, debt and equity crowdfunding. Energy4Impact will be joined by crowdfunding platform partner Lendahand, as well as crowdfunded entrepreneurs Sosai Renewable Energies of Nigeria to present their experiences.
This month, our presenters/discussants will be Energy4Impact's Davinia Cogan, who has been managing their crowdfunding research programme, Koen The, CEO of Lendahand Ethex and Habiba Ali, Managing Director of Sosai RE. In addition to presentations on their experiences, the webinar will include a panel discussion on the various challenges and opportunities of crowdfunding energy access between the presenters, as well as - of course - an opportunity for Q&A with all webinar participants.

FOR MORE INFORMATION, PLEASE VISIT e4sv.org
In September 2017, the Low Carbon Energy for Development Network (LCEDN) held its annual conference on the topic of "Equity and Energy Justice" at Durham University, UK. As a follow-up to this conference, we held two webinars to share highlights from the conference.
The first webinar focussed on energy justice. This month, we examined a second theme from the conference, and focused on questions of how academic research can best have impact at the grassroots of energy access and productive use, how that "knowledge gap" can be closed, and what some of the most effective solutions might be for ensuring that research can be applied effectively and equitably.
The speakers included Practical Action's Sarah Begg, who has been leading a participatory learning study with LCEDN looking at how academic research impacts the grassroots. She will be joined by her colleague from Practical Action's Bangladesh office, Iffat Khan, who will present some of the specific outcomes and experiences of the study in Bangladesh. Finally, the Smart Villages Initiative will share the global perspectives they have been able to gather on bridging academic research and making it relevant to energy access practitioners, entrepreneurs, and rural communities.

1891 - Primera discusión semicientífica sobre Una Nave Espacial Propulsada po...Champs Elysee Roldan
La primera discusión semicientífica sobre una nave espacial propulsada por cohetes la realizó el alemán Hans Ganswindt, quien abordó los problemas de la propulsión no mediante la fuerza reactiva de los gases expulsados sino mediante la eyección de cartuchos de acero que contenían dinamita. Supuso que la explosión de una carga transferiría energía cinética a la pared de la nave espacial y la impulsaría en la dirección deseada. Supuso que múltiples explosiones proporcionarían suficiente velocidad para alcanzar la órbita y la velocidad de escape.
El 27 de mayo de 1891, pronunció un discurso público en la Filarmónica de Berlín, en el que introdujo su concepto de un vehículo galáctico(Weltenfahrzeug).
Ganswindt también exploró el uso de una estación espacial giratoria para contrarrestar la ingravidez y crear gravedad artificial.
