  • When and why are certain data structures used in the context of web development?

    - by Ein Doofus
    While browsing around the MSDN I came across: http://msdn.microsoft.com/en-us/library/aa287104%28v=vs.71%29 which lists various data structures such as: Queues Stacks Hashtables Binary Trees Binary Search Trees Graphs (I believe there are also Lists) and I was hoping to get a high-level overview of when these various data structures can be used in the broad context of web development, and when used, why one data structure is generally used instead of any other one.

  • Is it okay for programmers to be given the task of outlining database requirements?

    - by L'Ingenu
    In my current job, dba's and programmers are divided in tasks. Any code that needs to be written in procedures dba's write, and programmers do only application code. The strange thing is that whenever a task needs to be defined/specced, programmers get the task, and we have to define all the procedures needed and what they should return. Is this a common practice in software development? Are programmers generally the ones tasked with building requirements for the database side?

  • Introduction aux algorithmes et aux structures de données, un cours par Thibaut Cuvelier

    En 1976, le livre Algorithms + Data Structures = Programs paraît : le postulat posé par ce titre est bien qu'un algorithme n'est rien s'il n'a pas de structure de données appropriée pour stocker ses données. On étudiera, dans cette introduction, tant les algorithmes principaux (tri, graphes %u2013 le bien connu Dijkstra mais aussi Bellman-Ford pour la recherche de plus court chemin) que des structures de données très fréquentes sur lesquelles viennent se construire des solutions élaborées à des problèmes complexes (pile, file, dictionnaire, etc.).

  • How to manage a Closed Source High-Risk Project?

    - by abel
    I am currently planning to develop a J2EE website and wish to bring in 1 developer and 1 web designer to assist me. The project is a financial app with a niche market. I plan to keep the source closed . However, I fear that my would-be employees could easily copy the codebase and use it /sell it to a third party especially when they switch jobs. The app development will take 4-6months and perhaps more and I may have to bring in people after the app goes live. How do I keep the source to myself. Are there techniques companies use to guard their source. I foresee disabling pendrives and dvd writers on my development machines, but uploading data or attaching the code in one's mail would still be possible. My question is incomplete. But programmers who have been in my situation, please advice. How should I go about this? Building a team, maintaining code-secrecy,etc. I am looking forward to sign a secrecy contract with the employees if needed too. (Please add relevant tags) Update Thank you for all the answers. I certainly won't be disabling all USB ports and DVD writers now. But I think I should be logging activity(How exactly should I do that?) I am wary of scalpers who would join and then run off with the existing code. I haven't met any, but I have been advised to be wary of them. I would include a secrecy clause, but given this is a startup with almost no funding and in a highly competitive business niche with bigger players in the field, I doubt I would be able to detect or pursue any scalpers. How do I hire people I trust, when I don't know them personally. Their resume will be helpful but otherwise trust will develop only with time. But finally even if they do run away with the code, it is service that matters after the sale is made. So I am not really worried for the long term.

  • Conditional Gridview Text - Checkboxes

    This code sample shows how to either show or make invisible, a checkbox in each row of the Gridview, along with making text conditional, based on certain criteria. In this case, if the Postal code starts with a non-numeric character, we change it to "Alt Text", and we set the Visible property of the checkbox in that row to "False"

  • Google I/O 2012 - Writing Polished Apps that have Deep Integration into the Google Drive UI

    Google I/O 2012 - Writing Polished Apps that have Deep Integration into the Google Drive UI Mike Procopio, Steve Bazyl We'll go through how to implement complete Drive apps. This is not an introduction to Drive apps, but rather how to build your product into Google Drive, and ensure that the experience is seamless for a user. We will also discuss how to effectively distribute your app in the Chrome Web Store. The example app built in this talk will demonstrate an example use case, but otherwise be production-ready.

  • Running C++ AMP kernels on the CPU

    - by Daniel Moth
    One of the FAQs we receive is whether C++ AMP can be used to target the CPU. For targeting multi-core we have a technology we released with VS2010 called PPL, which has had enhancements for VS 11 – that is what you should be using! FYI, it also has a Linux implementation via Intel's TBB which conforms to the same interface. When you choose to use C++ AMP, you choose to take advantage of massively parallel hardware, through accelerators like the GPU. Having said that, you can always use the accelerator class to check if you are running on a system where the is no hardware with a DirectX 11 driver, and decide what alternative code path you wish to follow.  In fact, if you do nothing in code, if the runtime does not find DX11 hardware to run your code on, it will choose the WARP accelerator which will run your code on the CPU, taking advantage of multi-core and SSE2 (depending on the CPU capabilities WARP also uses SSE3 and SSE 4.1 – it does not currently use AVX and on such systems you hopefully have a DX 11 GPU anyway). A few things to know about WARP It is our fallback CPU solution, not intended as a primary target of C++ AMP. WARP stands for Windows Advanced Rasterization Platform and you can read old info on this MSDN page on WARP. What is new in Windows 8 Developer Preview is that WARP now supports DirectCompute, which is what C++ AMP builds on. It is not currently clear if we will have a CPU fallback solution for non-Windows 8 platforms when we ship. When you create a WARP accelerator, its is_emulated property returns true. WARP does not currently support double precision.   BTW, when we refer to WARP, we refer to this accelerator described above. If we use lower case "warp", that refers to a bunch of threads that run concurrently in lock step and share the same instruction. In the VS 11 Developer Preview, the size of warp in our Ref emulator is 4 – Ref is another emulator that runs on the CPU, but it is extremely slow not intended for production, just for debugging. Comments about this post by Daniel Moth welcome at the original blog.
