p>Big Data on the farm

/p>

p>It's the world's oldest industry and one that you may not think was that forward-looking - but it's now experiencing an entirely new data-driven revolution. From drones that provide aerial surveys of crops, to combine harvesters measuring precisely the output of each square metre, to sensors that provide minute-by minute updates on the health of animals, farmers are handling an ever-growing amount of data. A chicken farmer will share his experiences with this new method of working. Rob Carter, co-founder of Field Margin, will be our special guest. Field Margin is a smartphone app that helps farmers manage their data. Our BBC Radio colleagues from 4's Farming Today have been covering the latest developments in farming technology throughout the week. They will be giving an exclusive report on Saturday's On Your Farm. https://forums.com.bz/ </p>

p>Minecraft in the classroom

/p>

p>Since Microsoft purchased Minecraft we've heard nothing about its plans for the loved world-building game. However, this week the software giant has announced a major expansion into education, launching a classroom version of the game. Our Jane Wakefield went along to BETT, the UK's giant educational technology trade show, to talk to Microsoft about the plan which allows children to learn through Minecraft at school and then continue playing at home. To sign in to the education edition, schools will require an Office 365 account. We'll be asking if this is part Microsoft's strategy to challenge Google as the leading software provider in the classroom.

p>Lessons from a Kickstarter

/p>

p>Kickstarter received a lot criticism following the Zano mini-drone project went down to earth in November. So the crowdfunding platform hired an investigative reporter to determine what went wrong. This week Mark Harris published his 13,000 word report, which is an excruciating report on how to not run a technology business and a warning to those who don't understand that backing a crowdfunded project is not the same as ordering something from Amazon. We speak to him about his thoughts on crowdfunding as a method of getting tech ideas off-the-ground.

p>Doom increases in level

/p>

p>Twenty-three years have passed since the original game Doom was released, there is still a dedicated group of players. This week they're celebrating a milestone. The first new level since the mid-1990s has been released by one of the original developers John Romero. Our reporter Zoe Kleinman has been talking to him about the new level - he says that he was a bit nervous about how the community would react, but the majority of fans have been overwhelmingly favorable.
