One problem related to composite pattern is how to implement operations over child collections. Composite classes have children and leaf classes not. There are many ways how to solve the problem of where and how to keep child nodes collection. In this posting I go through different options and analyze those solutions through different code examples.The post Composite Pattern: Handling child node collections appeared first on Gunnar Peipman - Programming Blog.
As long-time customers know, we release our new major versions at the end of the first half of the year and at the end of the second half (June and December, usually). A couple of weeks ago, we released DevExpress Universal 13.2, so this week it’s the turn of our VCL subscription. DevExpress VCL 13.2 continues our current momentum to help you show your customers and end-users that Delphi and C++Builder can be used to produce modern apps, with fresh designs and up-to-the-minute user experiences. It really is time to move away from those grey late-90s application designs. So
if I had to pick a topic, I suppose the main motif with VCL 13.2 is modernizing your apps. New themes, touch capabilities, tablet-like behaviors all provide a framework for creating a modern UI. New Features and Enhancements More Touch. Continuing our efforts to give you touch-centric capabilities in our controls, we’ve added optimized touch behaviors to the Filter Control, the Page Control, the Tab Control, the Date Editor (shown), and the Blob Editor.
Themes. Modern apps need modern themes. Meet Metropolis, Metropolis Dark, Office 2013 Light Gray, and Office 2013 Dark...(Read whole news on source site)
As some of you may be aware, Microsoft has released some important performance and stability updates to both SQL Server 2008 R2 (CU9) and SQL Server 2012 SP1 (CU7) via the cumulative updates release vehicle in the last couple of months. As I raised IT tickets for their download and installation on our development servers, someone from the team asked me a question: SQL Server CUs are not part of the Microsoft update that downloads patches on “patch Tuesday”. How do you know when Microsoft releases cumulative updates for download? The answer is
quite simple – Microsoft publicly announces the availability of the CUs on their website! If you want to remain up-to-date with the latest of cumulative patches, please feel free to visit the following pages every now and then: The SQL Server 2008 R2 builds that were released after SQL Server 2008 R2 Service Pack 2 was released [Link] The SQL Server 2012 builds that were released after SQL Server 2012 Service Pack 1 was released [Link] Please note that as soon as a service pack is released, subsequent...(Read whole news on source site)
The low efficiency of Hadoop computation is an undeniable truth. We believe, one of the major reasons is that the underlying computational structure of MapReduce for Hadoop is basically of the external memory computation. The external memory computation implements the data exchange through the frequent external memory read/write. Because the efficiency of file I/O is two orders of magnitude lower than that of memory, the computational performance of Hadoop is unlikely high.
While for the normal users, they usually have a small size of cluster with only tens or scores of nodes. The cluster environment is relatively reliable and the fault
probability is very low. Moreover, most realtime computations would complete quite quickly in each run. Users can always choose to recompute even on errors, not having to consider much about the fault tolerance during computation. In this case, using esProc and alike parallel computing scheme to offer double supports for both in- and external memory computations is a better choice. esProc is also based on Hadoop whose in-memory computing can be utilized for the middle-and-small scale cluster to have a much higher performance.
In the example below, we will use a typical example for grouping to illustrate how esProc...(Read whole news on source site)
