  • Extending SSIS with custom Data Flow components (Presentation)

    Download the slides and sample code from my Extending SSIS with custom Data Flow components presentation, first presented at the SQLBits II (The SQL) Community Conference. Abstract Get some real-world insights into developing data flow components for SSIS. This starts with an introduction to the data flow pipeline engine, and explains the real differences between adapters and the three sub-types of transformation. Understanding how the different types of component behave and manage data is key to writing components of your own, and probably should but be required knowledge for anyone building packages at all. Using sample code throughout, I will show you how to write components, as well as highlighting best practice and lessons learned. The sample code includes fully working example projects for source, destination and transformation components. Presentation & Samples (358KB) Extending SSIS with custom Data Flow components.zip

  • Why is implementing copy-paste in a touch screen based smartphone such a big deal?

    - by EpsilonVector
    I'm not entirely sure this is on-topic, but it definitely needs a programmer's understanding to be answered, and deals with general development (for a specific scenario) as opposed to a specific piece of code. In a way it also translates into "what are the challenges in doing X in a touch screen app", and similar questions have been asked here in the past. So here it is: When Apple didn't implement copy-pasting on the iPhone since version 1 I just assumed it was a UI issue- they were waiting until they figured out a good UI for it. But now the idea is out there, and Microsoft still released Windows Phone 7 without copy-pasting, promising it'll be ready in a few months. My question is: why does this takes a few months to implement? Are there some technological challenges that are unique to programming for a touch screen that I'm not familiar with?

  • Spherical harmonics lighting - what does it accomplish?

    - by TravisG
    From my understanding, spherical harmonics are sometimes used to approximate certain aspects of lighting (depending on the application). For example, it seems like you can approximate the diffuse lighting cause by a directional light source on a surface point, or parts of it, by calculating the SH coefficients for all bands you're using (for whatever accuracy you desire) in the direction of the surface normal and scaling it with whatever you need to scale it with (e.g. light colored intensity, dot(n,l),etc.). What I don't understand yet is what this is supposed to accomplish. What are the actual advantages of doing it this way as opposed to evaluating the diffuse BRDF the normal way. Do you save calculations somewhere? Is there some additional information contained in the SH representation that you can't get out of the scalar results of the normal evaluation?

  • Where to start for writing a simple java IDE?

    - by AedonEtLIRA
    I would like to start working on my own custom IDE. The biggest reason I want to work on the IDE is to help me gain an even greater, more intimate understanding of java (and other languages I add into it.) I don't want to do anything super fancy or revolutionary, I'd be happy if I could create something as compact as the BlueJ IDE I used in high school and be content. I have a few question on the specifics of the task that I hope I can get cleared up before I start investing time in this: Is there anything I should be aware of when writing the parser? Does anyone have any pointers that I should be aware of; pitfalls, brick walls or other constraints?

  • Not able to install ubuntu 12.10

    - by Janet
    When I try to install Ubuntu on my computer I get this error: /var/cache/apt/archives/compiz-gnome_1% 3a0.9.8.4+brz 3412-0ubuntu0.1_i386.deb and /var/cache/apt/archives/metacity-common_1% 3a2.34.8-0ubuntu4_all.deb Ok, since I'm not a whiz at installing linux or understanding it...When these two things popped up it stated that the file was corrupted and there were too many errors to complete the install. Now, does that help? I had Ubuntu 12.04 LTS on my computer and wanted to upgrade, now I have nothing on my desktop and when I tried to install by using my usb pen, nothing happen and I also have it on dvd and tried to install from that and nothing still happen. So maybe someone can tell me why it's not installing on my desktop? I have it on my laptop with Windows.

  • Update webreference gives troubles with different versions of dll

    - by Natrium
    In my application, I use some dll, let's say library.dll, version 1.0 In my webservice, I also use library.dll, but version 2.0 When I do an update of the webreference, the classes inside of the dll are also generated in the webreference. And this gives troubles because in my application, the classes that are defined in the dll now are also available in the reference and there is a mismatch. How can I solve this? I need to be able to tell the webservice to ignore the dll-code when updating the webreference in the one or the other way. I use Visual Studio 2008.

  • Can an object oriented program be seen as a Finite State Machine?

    - by Peretz
    This might be a philosophical/fundamental question, but I just want to clarify it. In my understanding a Finite State Machine is a way of modeling a system in which the system's output will not only depend on the current inputs, but also the current state of the system. Additionally, as the name suggests it, a finite state machine can be segmented in a finite N number of states with its respective state and behavior. If this is correct, shouldn't every single object with data and function members be a state in our object oriented model, making any object oriented design a finite state machine? If that is not the interpretation of a FSM in object design, what exactly people mean when they implement a FSM in software? am I missing something? Thanks

  • Kohana input & validation libraries - overlap?

    - by keithjgrant
    I'm familiarizing myself with Kohana. I've been reading up on the Input library, which automatically pre-filters GET and POST data for me, and the Validation libary, which helps with form validation. Should I use both together? The examples given in the Validation library documentation use the unfiltered $_POST array instead of $this->input->post(). Seems to me it would be more secure to chain the two, but the two sets of documentation seem to make no mention of each other, so I don't know if this would be redundant or not.

  • What is the most effective order to learn SQL Server, LINQ, and Entity Framework?

    - by user1525474
    I am trying to get some advice on what order I should learn about SQL Server, LINQ, and Entity Framework to be able to better work with ASP.NET Webforms and MVC. From what I've been able to learn so far, many recommend learning LINQ or Entity Framework before learning SQL Server. It also appears that many companies are looking for people with knowledge in LINQ-to-SQL and Entity Framework without mentioning SQL Server. However, my understanding is that LINQ-to-SQL and Entity Framework translate code into SQL Server queries, making this a poor approach. Is there a correct or best order in which to learn these technologies?

  • Does google contribute ranking from cdn.example.com to example.com?

    - by DesignerGuy
    Background From my understanding, http://mywebsite.com/image.jpg, can help the ranking of http://mywebsite.com in a search engine, such as Google (obviously the search engine of primary concern). So, SEO-wise, moving an image to http://whatever-cdn.com/my-account/image.jpg is bad. A popular solution is to use a CNAME record, such as http://cdn.mywebsite.com, so that image.jpg can be accessed at http://cdn.mywebsite.com/image.jpg. The question Does http://cdn.mywebsite.com/image.jpg rank as effectively as http://mywebsite.com/image.jpg ? Does it help boost the main http://mywebsite.com ? Or, does it rank independently because it is a subdomain? Is there another option (a way to use a CDN without sacrificing ranking)?

  • HTML5 article tag application for the iPad/iPhone

    - by dspencer
    I've used article tags on websites. My understanding and practice is to use the article tag for publication content. I always use HTML/HTML5 tags as their intended purposes and not at will. Recently, I've seen an HTML template that uses the article tag for the non-publication page content such as the content of an About Us page or any other generic page. I asked the why it was used this way and the (vague) explanation was that it had to do with the way the iPad read the tag. Is this true?

  • .mdf Database Filetype

    - by James Izzard
    Would somebody be kind enough to correct my understanding of the following (if incorrect)? Microsoft's .mdf file-type can be used by both the LocalDB and the full Server database engines (apologies if engine is not the correct word?). The .mdf file does not care which of these two options are accessing it - so you could use either to access any given .mdf file, provided you had permissions and password etc. The LocalDB and the SQL Server are two options that can be interchangeably chosen to access .mdf files depending on the application requirements. Appreciate any clarification. Thanks

  • Healthcare Mobile Database Synchronization Demonstration

    - by Jim Connors
    Like many of you, I learn best by getting my hands dirty.  When confronted with the task of understanding a new set of products and technologies and figuring out how they might apply to a vertical industry like healthcare, I set out to create a demonstration.  The video that follows aims to show how the Oracle embedded software portfolio can be applied to a healthcare application.  The demonstration utilizes among others, Java SE Embedded, Berkeley DB, Apache Tomcat, Oracle 11gR2 and Oracle Database Mobile Server. Eric Jensen gives a great critique and description of the demo here.  To sum it up, we aim to show how live medical data can be collected on a medical device, stored in a local database, synchronized to a master database and furthermore propagated to a mobile phone (Android) application.  Come take a look!

  • Is the copy/paste approach professionally viable when working with the Google Maps API?

    - by Ian Campbell
    I find that I understand much of the Javascript concepts used in the Google Maps API code, but then again there is quite a bit that is way over my head in syntax. For example, the geocoder syntax seems to be of Ajax form, though I don't understand what is happening under the hood (especially with lines like results[0].geometry.location). I am able to modify the body of if (status == google.maps.GeocoderStatus.OK) for different purposes though. So, being that I am able to take various code from the Developer's Guide and rework it to an extent for my own purposes, all the while not fully understanding what Google Maps is actually doing, does this make me a copy-paste programmer? Is this a bad practice, or is this professionally viable? I am, of course, interested in learning as much as I can, but what if time-constraints outweigh the learning process?

If these components are not effectively shared by project leads and understood by stakeholders, project outcomes can be jeopardized and budgets may incur unnecessary risk. As reported by PMI’s 2013 Pulse of the Profession, an organization’s ability to meet project timelines, budgets and especially goals significantly impacts its ability to survive—and even thrive. The Pulse study revealed that the most crucial success factor in project management is effective communication to all stakeholders—a critical core competency for public agencies. PMI’s 2013 Pulse of the Profession report revealed that US$135 million is at risk for every US$1 billion spent on a project. Further research on the importance of effective project team communication uncovers that a startling 56 percent (US$75 million of that US$135 million) is at risk due to ineffective communication. Simply stated: public agencies cannot execute strategic initiatives unless they can effectively communicate their strategic alignment and business benefits. Executives and project managers around the world agree that poor communication between project team members contributes to project failure. A Forbes Insights 2010 Strategic Initiatives Study “Adapting Corporate Strategy to the Changing Economy,” found that nine out of ten CEOs believe that communication is critical to the success of their strategic initiatives, and nearly half of respondents cite communication as an integral and active component of their strategic planning and execution process. Project managers see it similarly from their side as well. According to PMI’s Pulse research, 55 percent of project managers agree that effective communication to all stakeholders is the most critical success factor in project management. As we all know, not all projects succeed. On average, two in five projects do not meet their original goals and business intent, and one-half of those unsuccessful projects are related to ineffective communication. Results reveal that while all aspects of project communication can be challenging to public agencies, the biggest problem areas are: A gap in understanding the business benefits. Challenges surrounding the language used to deliver project-related information, which is often unclear and peppered with project management jargon. Public agencies -- federal, state, and local -- have difficulty communicating with the appropriate levels with clarity and detail. This difficulty is likely exacerbated by the divide between each key audience and its understanding of project-specific, technical language. For those involved in public sector project and portfolio management, I would be interested to hear your thoughts and please visit Primavera EPPM solutions for public sector.

  • XNA Transparency depending on drawing order?

    - by DarthRoman
    I am drawing two 3D objects, both of them can fade from opaque to transparent independently, and they can intersect between them (so you cannot say when one of them is before the other one). Look at the image for a better understanding (one of the object is a terrain and the other one an area): Now, if I apply transparency to both of them, and draw the terrain before the area, the terrain is not transparent respecting to the area, but the area is: And finally, if I draw the area before the terrain, then the area is not transparent respecting of the terrain: QUESTION: How can I make all the objects transparent to the rest of objects without depending on the drawing order?

  • Who Knows AppWeb HTTP Server And It's Embedded PHP?

    - by Andi
    Hi all, on my search for a fast but comfortable web server I dropped into the homepage of EmbedThis(TM) AppWeb(TM) HTTP server. This one has 2 licencse models, GPLv2 and a commercial one with support. On the first view it looks good: the footprint is not too big, it is fast and it has a lot of configuration otions. The most important thing would be a fast PHP execution using a built-in PHP library. Unfortunately this PHP library doesn't include every option, especially "gettext" which one I need for I18N. My target platform is Linux on an embedded device with an ARM based CPU. Does anybody have experiences with the issues mentioned above? Kind regards, Andi

  • What's the difference between stateful and stateless?

    - by Pankaj Upadhyay
    The books and documentation on the MVC just heap on using the Stateful and Stateless terms. To be honest, i am just unable to grab the idea of it, what the books are talking about. They don't give an example to understand any of the either state, rather than just telling that HTTP is stateless and with ASP.NET MVC microsoft is going along with it. Am I missing some fundamental knowledge, as i can't understand what is stateful and why is stateful and same goes for stateless. A simple and short example that talks about a control like button or textbox can be simplify the understanding i suppose.

  • How does the "Fourth Dimension" work with arrays?

    - by Questionmark
    Abstract: So, as I understand it (although I have a very limited understanding), there are three dimensions that we (usually) work with physically: The 1st would be represented by a line. The 2nd would be represented by a square. The 3rd would be represented by a cube. Simple enough until we get to the 4th -- It is kinda hard to draw in a 3D space, if you know what I mean... Some people say that it has something to do with time. The Question: Now, that is all great with me. My question isn't about this, or I'd be asking it on MathSO or PhysicsSO. My question is: How does the computer handle this with arrays? I know that you can create 4D, 5D, 6D, etc... arrays in many different programming languages, but I want to know how that works.

  • convert HTML to PDF with dynamic image using PD4ML

    - by vishwanath
    We are using PD4ML library to convert HTML to PDF. Is there any way with which I can include a image from the internet in my HTML to convert it into PDF. I am having problem in getting the image into PDF. I tried using base parameter in the PD4ML library but that didn't worked out. May be I am doing something wrong or PD4ML doesn't support including image from the internet. Because when I discussed my problem with other colleagues, found out that when we use the image from local server it gets to the PDF but image from internet don't. I am bound to use PD4ML, so solution with PD4ML only will be highly appreciated.
