Barriers to Active TravelHow hard can it be?

Alison delivered a short presentation detailing the ‘journey’ she has undertaken over the last few years in her quest to get more people travelling actively. On the face of it, this seems like a fairly easy objective to achieve, but Alison has learned (sometimes the hard way) that things are not as simple as they seem. This presentation will detail some of the barriers present to achieving this - the conflicting aims and interests, and how she has managed to overcome some of them. For questions: Send email Alison.Millbourn@kirklees.gov.uk

The missing link in your network - Empower your people through open interact...

Companies of all sizes have realized the power of their people network and are continually introducing new tools and processes to further connect their people and cultivate their network. Unfortunately, many companies have inaccurately emphasized the technology network over their people network which has devalued engagement and turned employees away from collaborative tools. Therefore, it is critical to focus not only on how the network can tap into each employee, but how each of them can tap into the network.

Data storage systems

The presentation from PiterPy Meetup #10 Hardcore about the data structures used in databases for storing and retrieving data. Two approaches to data processing are considered: OLTP and OLAP. SQL, NoSQL and New SQL databases are discussed. The tradeoffs that the developers face when creating storage systems are shown. Also the methods of data storage and interaction with the database provides CPython are considered. The presentation and the list of references and books helps more easily navigate the data storage engines and understand which tool is better suited for a particular task.
