• 3D touch "Minority Report" style interface - what platform gets me there the fastest?

  - by Ross Braden

  I'm working on a project that requires touch interface, though the use case is desktop more than mobile. Want to start out platform agnostic, not a mobile app. There will be gridwork type of 3D objects and diagraming being represented - think AutoCAD or Minority Report. Want to build a prototype that will have hooks into a database to represent the data. Any advice on what tools to use both for the design and the development of the functionality is greatly appreciated. Thanks!

• AdventueWorks Design Patterns Project - Part 1

  - by RonGarlit

  This is the presentation I did tonight at PHILLYNJ.NET.  It is the first in a multi-part of a series on the Applied Design Patterns.   The solution files are working code with design pattern notes in the comment blocks. After the overview and higher level discussions on Enterprise Design Patterns I reviewed the low level Database Access Library of code.  With walk-throughs of the the code and unint test. After that we went through the ProductPhotoConsoleTest Application that performed intergration testing of the DBAccess Class with the AdventureWorks ProductPhoto table extracting the photos and writing them to a file folder. The Demo code and PowerPoint can be obained from this link.  https://skydrive.live.com/?wa=wsignin1.0&cid=29e34e9a8650bb9e#!/?cid=29e34e9a8650bb9e&sc=documents&id=29E34E9A8650BB9E%21151 Please note that I use Visual Studio 2010 Ultimate.  If you have a lesser version the Modeling projects likely will not work or have limited functionality and you should unload that project to prevent warning. Enjoy! --Ron

• ETL Software Research Question

  - by WernerCD

  Where I work, we use an in-house ETL solution that's homegrown and has been around for 5-10 years. I'm still new to my data analysis job, but I was wondering about the ETL tools that are out there. This is a new area for me. My situation, and job, is basically digging in a set of databases (DB2, SQL2005, Citrix, Ancient Cobol Database with a SQL Wrapper on top, MySQL, etc). Gather the desired information. combine the different datasets into one set. output into a file of choice (CSV, Tab Separated, Pipe Separated, XLS, etc). FTP to customer. I guess what my real question is, given my job, what are some good ETL suites that I can look at and compare to my in-house tools? This is more to research some other options. Ultimately, I'd either suggest a new solution or get options/ideas to improve our current app.

• Older PHP v/s newer PHP version [closed]

  - by Monty

  My company is building a website with database. Programmer's used PHP 5.0. My Service Provider (shared) in the meantime upgraded to PHP 5.3.0. Fixes have been on going and seem endless... Do I move to VPS and install older PHP or should we rebuild with newer PHP? When working remotely with programers what is the protocol regarding delivery of all code? Please what is the industry standard? I need an independent to review their work. How should this be approached?

• Architecture for dashbaord showing aggregated stats

  - by soulnafein

  I'm trying to find the best architecture for an application that shows a dashboard with aggregated stats that come from another one (e.g. number of sales in the last 12 months, current sales this month, a fairly complex score, performance of users over last 30 days, etc.) There is a fair bit of business logic that lives in Application 1 but the aggregated data gets saved in Application 2 (dashboard). What's the best way to create the aggregate data? 1) Pull data directly from Application 1 database and duplicate business logic for score calculation etc. 2) Push data from Application 1 to Application 2 somehow 3) Aggregate data in Application 1 on the fly and provide and api for Application 2 4) Other (probably) Please suggest solutions, Thanks.

• One Week on New Servers and Everything is Great

  - by Jeff Julian

  It has been a week since we moved our Geekswithblogs.net System to a new set of load balanced servers and everything has been going great.  I am so amazed at the performance of the new hardware.  On average, we only use less than 5% of the CPU at any given moments or the database and web servers.  I have seen a performance boost in page load as well, but I will have to confirm that with the statistics as they roll in.  This is all in preparation for a new community we are launching with some friends that we will be announcing shortly.  We will be launching a nice little contest for our bloggers as well.

• Getting Started with Hashing in SQL Server

  Encryption brings data into a state which cannot be interpreted by anyone who does not have access to the decryption key, password, or certificates. Hashing brings a string of characters of arbitrary size into a usually shorter fixed-length value or key. Here's how to get started using it.

• New Endpoint options that enable additional application patterns

  - by kaleidoscope

  The two communication-related capabilities:  a) inter-role communication and b) external endpoints on worker roles enable new application patterns in Windows Azure-hosted services. Inter-role Communication - A common application pattern enabled by this is client-server, where the server could be an application such as a database or a memory cache. External Endpoints on Worker Roles - A common application type enabled by this is a self-hosted Internet-exposed service, such as a custom application server.

• How to organize my 1000s of PDF?

  - by mmb

  I have a huge collection of PDF. Mostly it consists of research papers, of self-created documents but also of scanned documents. Right now I drop them all in one folder and give them precise names with tags in the filename. But even that gets impractical, so I am looking for a PDF library management application. I am thinking of something like Yep for Mac, with the following features: PDF cover browsing (with large preview, larger than Nautilus allows) tagging of PDF (data should be readable cross-platform) possibility to share across network (thus rather flat files than database) if possible: cross-platform Mendeley seemed to be a good choice, but I am not only having academic papers and don't want to fill it all metadata that is required there. The only alternative I could find thus far is Shoka, but the features are limited and developments seems to have stopped already.

• How to structure an application which reads UPC barcodes

  - by tugberk

  I have no previous experience on creating a project for a seller which will use barcode reader. I am trying to put together a small project but I cannot figure out how the pieces should glue together. I will create a sample with Motorola Scanner SDK to read barcodes and from that point, I have couple of questions: How UPC barcodes work in general? AFAIK, a barcode stores the manufacturer and product info but no price data. Should I store price information inside a database which corresponds to barcode data? I would really appreciate if you can guide me here.

• Writing a spell checker similar to "did you mean"

  - by user888734

  I'm hoping to write a spellchecker for search queries in a web application - not unlike Google's "Did you mean?" The algorithm will be loosely based on this: http://catalog.ldc.upenn.edu/LDC2006T13 In short, it generates correction candidates and scores them on how often they appear (along with adjacent words in the search query) in an enormous dataset of known n-grams - Google Web 1T - which contains well over 1 billion 5-grams. I'm not using the Web 1T dataset, but building my n-gram sets from my own documents - about 200k docs, and I'm estimating tens or hundreds of millions of n-grams will be generated. This kind of process is pushing the limits of my understanding of basic computing performance - can I simply load my n-grams into memory in a hashtable or dictionary when the app starts? Is the only limiting factor the amount of memory on the machine? Or am I barking up the wrong tree? Perhaps putting all my n-grams in a graph database with some sort of tree query optimisation? Could that ever be fast enough?

• Hybrid Columnar Compression

  - by user12620172

  You heard me in the past talk about the HCC feature for Oracle databases. Hybrid Columnar Compression is a fantastic, built-in, free feature of Oracle 11Gr2. One used to need an Exadata to make use of it. However, last October, Oracle opened it up and now allows it to work on ANY Oracle DB server running 11Gr2, as long as the storage behind it is a ZFSSA for DNFS, or an Axiom for FC. If you're not sure why this is so cool or what HCC can do for your Oracle database, please check out this presentation. In it, Art will explain HCC, show you what it does, and give you a great idea why it's such a game-changer for those holding lots of historical DB data. Did I mention it's free?

• Who created that user?

  - by AaronBertrand

  Twitter has provided some great fodder for blog content lately. And twice this week, I've found an excuse to take advantage of the default trace. Tonight @meltondba asked: I'm trying to find who created a user act in a DB It is true, SQL Server doesn't really keep track of who created objects, such as user accounts in a database. You can get some of this information from the default trace, though, since it tracks EventClass 109 (Audit Add DB User). If you run this code: USE [master] ; GO CREATE LOGIN...(read more)

• Which DB should I use for my newbie program?

  - by knijo

  I'm really new to programming, and I need some advice. I'm currently working on a very simple program to maintain a list of users at a company, as well as their clock in and clock out info. I would like to make this application easy to distribute (on a cd probably), and I'm looking for advice on which database to use for storing my data. My application is implemented using java and swing. A friend recommended MySQL, but I don't want to go installing the db server on every computer the application is installed on. Another friend recommended Access. Any tips would be greatly appreciated

• How are hybrid VB6/.Net applications functioning in the Real World?

  - by Dabblernl

  I am maintaining a VB6 application and we are studying how to migrate to .Net We are considering doing this gradually by implementing new features in COM visible .Net classes and migrating existing functionality slowly. I found some instructive 'Hello World' examples about how to do this and it works fine with our App. But how is the real world behaviour of these hybrid applications? Are they stable, maintainable? Particular of our program is that more users on the same computer will use it by switching user accounts. EDIT: The VB6 app reads data from a USB connection and stores it in an Access database. The user can call up various views on the data. The data is cached in a hardware device, so interuptions in the reading of it are not fatal.

• Removing unnecessary joomla CMS components

  - by Gaz_Edge

  Background I have been developing a web application. I have been using Joomla platform and CMS as the base from my application. My application relies heavily on the joomla platform, but uses very few features of the CMS (I have to login users etc so I use the _users component of the CMS). Question What is the best way to start removing some of the excess CMS that I don't need? For example when I being building my production site, I will want to avoid creating a load of joomla component database tables etc. I have read that an application can be build from the ground up using just the joomla platform, but i still want to include the _users component and would also like to avoid having to start coding all the session handling aspects. Any advice?
