I expect Neil Fantom is the only one more excited than me about this, but seriously well done to the +World Bank  data team on launching the OPEN DATA TIME MACHINE!

What is it? It's a tool that lets you analyze and visualize different vintages and revisions of a published time series. So when you hear phrases like "revised GDP numbers" or "revised inflation figures" you can now compare the different data side by side and see if any conclusions you initially drew need to be updated as well.

Image Source: Wikimedia Commons Time travel is, of course, the stuff of science fiction. H. G. Wells wrote about it in 1895, and it’s been fertile territory for film and television makers ever since. But the ability to store and retrieve digital records has at least made it possible to travel back in time with data... For users of statistics, it turns out this can be a pretty handy thing to do: estimates and measures of many indicators get revise...

    I was lucky to be in Berlin with some colleagues earlier this month for the 2014 Open Knowledge Festival and associated fringe events. There’s really too much to distill into a short post - from Neelie Kroes, the European Commissioner for Digital Agenda, making the case for “Embracing the open opportunity” to Patrick Alley’s breathtaking accounts of how Global Witness uses information to expose crime and corruption in countries around the wor...

How do you define #BigData?

By December 2013, "meaningless buzzword" would be the most honest answer, but before the label "big data" became simply another way to publish more books, wow investors, and dupe customers, it actually was trying to make a real distinction.

My short, quippy answer has generally been "more data than I can fit on my phone" (i.e. more than 48GB serialized). +Tariq Khokhar told me on Twitter that he prefers "more data than I can pick up."

My longer, more considered answer is that big data is data that -- because of its size, not its nature -- we can't handle using conventional tools like relational databases (or hierarchical databases, RDF triple stores, etc.). Relational databases can easily store, analyze, query, and report on millions or tens of millions of rows, so millions of rows isn't "big data." At billions of rows, you're starting to strain the capacity of current RDBMS -- you might have to partition your data in complex ways and then merge the results, for example -- so I suspect that's when you start thinking about non-relational, distributed hashing approaches like Hadoop.

Once you make the jump to "big data" you're giving up some valuable stuff like internal consistency, but you're gaining the ability to scale. Depending on what you're trying to accomplish, the answers you get over a slightly inconsistent dataset of 10 billion nodes could be more interesting than the answers you get over a consistent dataset of 10 million nodes.

So that's my tentative answer, for today, anyway. What's yours?

Fair point, though I expect the 'big data' tools will also prove useful for smaller, complex tasks. Hopefully NSA-style tools will trickle down and find a home in other places.

1) Water covers 70% of the Earth, but it’s only 1/1000th of the Earth’s volume This image from the US Geological Survey shows what would happen if all the Earth’s water - everything from oceans and seas to ice caps, lakes and atmospheric vapor - was removed from the surface and combined into a single sphere. By volume, the Earth is about 1 trillion or 1,000 billion cubic kilometers. All of the earth’s water comes in at a thousand times small...

Hey Alex - I went though the same decision process a few months ago: I ended up with a 15" non-retina MBP. My reasons for going for it:

- hi-res matte (not glossy) display option which I find preferable to the retina for 95% of the coding, writing and a/v work I do. Movies look nicer on the glossy retina but that's about it for me.

- I want fast AND plentiful storage. I replaced the internal HDD with a (relatively) inexpensive Samsung 256GB SSD and swapped the optical drive with a caddy to house the 1TB HDD that came with it: result is a super-fast machine with heaps of storage.

- overall, with 16gb of third party ram and the SSD switcheroo + AppleCare, the non retina machine comes out a few hundred bucks cheaper than the closest configured retina. As a bonus I could use my existing magsafe power adapters..

Good luck!
 
OK, techie friends: if you were going to buy a new Apple laptop, what would it be -- and why? I want a 15" screen, so the Air is out. What's the general consensus on Retina vs non-Retina machines?

The UNDP just launched an open data site for the projects and operations. Here's my take - what do you think?

Hi Tariq,
I think its a great step forward, however what I am trying to develop is a map of open source data regarding climate change, including projects, initially in Tanzania. This will use both open and crowd source data, and even potentially give citizens the ability to rate the success of each project, link NGO's together to support projects and also local solutions that can be replicated with the assistance of funding. Take a look at www.conservationinteraction.org. Asante!
