This slide was used for a meetup event to report Social Good Summit (www.mashable.com/sgs), and discuss the context of social media for social good in Japan (10/2/2011)
Yes, it’s already that transitional time when our current year ends and another begins, and today and tomorrow are quickly changing hands. Rather than look back at significant trends of the past 366 days (2012 was a leap year, remember?), we asked a wide variety of technologists, designers, and strategists across frog’s studios around the world to take a look to the future. The near future, that is. “Near” in that 2013 is not only upon us, but also “near” in that these technologies are highly feasible, commercially viable, and are bubbling up to the surface of the global zeitgeist. We believe you’ll be hearing a lot more about these trends within the next 12 months, and possibly be experiencing them in some form, too.
Here's our second annual list of Tech Trend predictions for the coming year. There are 20 individual forecasts and, new for 2013, we've also related each prediction to larger waves in business, culture, and innovation.
1) The document discusses the opportunity for technology to improve organizational efficiency and transition economies into a "smart and clean world."
2) It argues that aggregate efficiency has stalled at around 22% for 30 years due to limitations of the Second Industrial Revolution, but that digitizing transport, energy, and communication through technologies like blockchain can help manage resources and increase efficiency.
3) Technologies like precision agriculture, cloud computing, robotics, and autonomous vehicles may allow for "dematerialization" and do more with fewer physical resources through effects like reduced waste and need for transportation/logistics infrastructure.

先日パリで開催したOpenStack Summit 2014 Parisで講演した内容を日本語でお伝えいたします。
You will face many problems when you start designing your OpenStack Cloud because of a lack of full design architecture information. For example, there are many Neutron plugins, but it is difficult to choose the best plugin and its configuration to get a high throughput of a Virtual Machine (VM) and achieve a High Availability (HA) of L3 Agent. Also, we couldn’t find information for how much computing resource (CPU, Memory and HDD) is required for management and operation servers (e.g. API, RabbitMQ, MySQL and Monitoring etc.).
We built OpenStack Icehouse Cloud on 100 physical servers (1600 physical cores) without using commecial software, and did several performance and long-run tests to address these problems.
In this talk, we will present performance comparison of Neutron ML2 plugin implementations (Open vSwitch and Linux Bridge), tunnelling protocols (GRE and VXLAN) and physical network configurations (Network Interface Bonding and Server Side Equal Cost Multi Path) to achieve 10Gbps at a VM, and the L3 Agent HA we implemented. Also, we will present how much computing resource we used and each server loads to operate the cloud. Finaly, we will share our Ansible Based OpenStack deployment and management tool.
Key topics include:
- Performance comparison of OSS Neutron ML2 plugins (Open vSwitch and Linux Bridge) and tunneling protocols (GRE and VXLAN)
- Performance comparision of redundant network configurations (Network Interface Bonding and Server Side Equal Cost Multi Path)
- HA of L3 Agent (ACT/STBY) we implemented
- Ansible based deployment/operation tools
- Items we must watch for OpenStack operation
- Hardware specifications and resources we used to operate the Cloud
We will share a full design architecture and hardware sizing information for a large scale cloud and prove OSS based Neutron can handle a hundred servers.

- The document discusses Ansible Galaxy NG, an open source project that provides a platform for sharing Ansible roles and collections.
- The author deployed Ansible Galaxy NG locally using Ansible playbooks and configured it to integrate with the local Pulp repository to manage collections.
- This allows collections to be hosted privately while also maintaining integration with upstream sources like the Ansible Galaxy and Red Hat Automation Hub public repositories.
This document provides an overview and introduction to Ansible. It discusses the motivation for IT automation and introduces some key Ansible concepts including Ansible Core, command line tools, playbooks, inventory, modules, and plugins. It also demonstrates how to get started with Ansible, use ad-hoc commands, and write playbooks. The presenter provides examples of installing packages and copying files using playbooks.
