  • Temporal in SQL Server 2016

    @Davele: If I're reading your post correctly, except for Ex1 Q2, all other cases should be expressible and work correctly in the terms of "now" (irrespective of the temporal tables).

    For query Ex 1 Q2 temporal feature would be a pre-requisite to get the answer.

    Temporal would be really helpful if in the Ex Q1 you were asking, what is the difference between what was known to the system "as of", say, a month back about state of the manufacturing pipeline on July 1st, versus what is known now about the state of the pipeline on July 1st.

    Temporal support is useful in cases when one has to test a forecasting model to see what kind of a decision the model would make, if it had only knowledge about the world as it existed then, vs. decision that would be made know with all the updated and revised facts.

  • HDInsight on Linux

    Cisco uses RedHat to run their UCS-based "cluster in a box" big data appliances. As a smaller s/w vendor we develop everything on CentOS with HDP. For what it worth, support for CentOS would make our life easier, if our next client decides to go with a managed hadoop in the cloud.

    Ubuntu is definitely looks like an easier port than Windows HDP, but its' still an extra platform to target.

  • Cloud Cover 151: Azure Machine Learning with Parmita Mehta

    Looks pretty cool. I'm a bit surprised that there is no code samples in F#. Is it possible to add 3rd party or custom-build components into the tool panel? For example, to add a database connector or custom missing value proxy?

  • State of .NET (Keynote)

    I wonder if 100% managed code database drivers similar to tier 4 JDBC will be ever implemented in .NET. That would be a big relief - no dependency on availability and presence of a native client from a DB vendor and cross platform.

  • Ushering in the Era of Programmable Hardware

    Any plans to add FPGA support to SQL Server? Restrictions, projections, hashing and other functions that require single row to produce result seem like a logical candidates for offloading.

  • Silverlight TV 76: Animations on Windows Phone in the Bird Hunt Game

    @Duncanma: Controls works as long as player is not buffering. When it is buffereing none of the controls work in neither IE9 nor FF4. What's worse, there seem to be some bug in the player code that after a number of clicks on various buttons player just hangs and the only resolution is to close and restart the browser (at least that's true for IE9).

  • Tech·Ed North America 2011 Keynote Address

    Video is pain to watch in IE9 with SL. Link to high res WMV is broken.

  • A New NUI - Tobii Eyetracking Hardware

    Pretty cool technology.
    Blink once two select, double blink to execute action Wink

    Oh, and your boss will know exactly how long did you spend in front of the monitor looking at the code versus watching videos on C9 [blink, blink]

  • Cloud Cover Episode 41 - Windows Azure Toolkit for Windows Phone 7

    Good as always.

    So, was Steve making some sort of a point by playing only A major? Azure-Majure?

  • C9 Lectures: Yuri Gurevich - Introduction to Algorithms and Computational Complexity, 2 of n

    It seems that discussion about "sameness" of two or more algorithms has no point unless participating parties agrees on what sameness means. Which it turn requires definition of a meta algorithm to measure various properties of algorithms of interest and compute measure of sameness. So, question "are two algorithm the same" has no aswer in general case.

    For similar reasons, in order to pick a better algorithm, one has to disclose all the constaints and assumptions used to compute measure of "goodness".
