  • Going Beyond the Relational Model with Data

    SQL is a powerful tool for querying data, and for aggregating it. However, you can't easily use it to draw inferences, to make predictions, or to tease out subtle correlations. To provide ever more sophisticated inferences to businesses, the race is on to combine the power of the relational model with advanced statistical packages. Both IBM and PostGres are ready with solutions. And SQL Server? Hmm...

  • Question about Byte-Pairing for data compression [closed]

    - by user1669533
    Question about Byte-Pairing for data compression. If byte pairing converts two byte values to a single byte value, splitting the file in half, then taking a gig file and recusing it 16 times shrinks it to 62,500,000. My question is, is byte-pairing really efficient? Is the creation of a 5,000,000 iteration loop, to be conservative, efficient? I would like some feed back on and some incisive opinions please. Best Regards.

  • Map multiple functions over a single data item

    - by Linus Norton
    I'm in the process of learning Scala and I came across a scenario today where I need to map multiple functions over a single piece of data and wondered if there was a formal name for this. It sort of feels like the inverse of map. I'm not sure this is the correct way of expressing it, but this is what I did: dmap(x: Object, fns: List[Function]) = fns.map(_(x)) Is there a built in way to do something similar? Is there a formal name for this function?

  • USING JSON SERIALIZATION FOR CODE BEHIND-JAVASCRIPT DATA COMMUNICATION

    Many of us went through a scenario like, can us pass a full of C# type/class to the javascript? Modify from there and again return back to C#?

Here we need to handle with JSON serialization techniques.

  • Is Juju deploy data accessible on the instances?

    - by ric_harvey
    When you launch an instance and explicitly name it using: juju deploy lamp website1 Is there a way on the newly created instance to get the data that tells the machine that its: called website1 or even better: a unit number such as website1/0, website1/1 etc etc The reason for doing this is that in my charm I wish to set the hostname to this value. I did wonder if it was set via ec2metadata but it doesn't seem to list this information.

  • Sorting data in the SSIS Pipeline (Video)

    In this post I want to show a couple of ways to order the data that comes into the pipeline. a number of people have asked me about this primarily because there are a number of ways to do it but also because some components in the pipeline take sorted inputs. One of the methods I show is visually easy to understand and the other is less visual but potentially more performant.
