  • How can one find software development work that involves directly the final end user?

    - by RJa
    I've worked in software development for 15 years and, while there have been signficant personal achievements and a lot of experience, I've always felt detached from the man/woman-on-the-street, the every day person, how it affects their lives, in a number of ways: the technologies: embedded software, hidden away, stuff not seen by the everyday person. Or process technology supporting manufactured products the size of the systems, meaning many jobs, divided up, work is abstract, not one person can see the whole picture the organisations: large, with departments dealing with different areas, the software, the hardware, the marketing, the sales, the customer support the locations and hours: out-of-town business parks away from the rest of society, fixed locations, inflexible: 9-5 everyday This to me seems typical of the companies I worked for and see elsewhere. Granted, there are positives such as the technology itself and usually being among high calibre co-workers, but the above points frustrate me about the industry because they detach the work from its meaning. How can one: change these things in an existing job, or compensate for them? find other work that avoids these and connects with the final end user? Job designs tend to focus on the job content and technical requirements rather than how the job aims to fulfil end user needs, is meaningful.

  • Purpose oriented user accounts on a single desktop?

    - by dd_dent
    Starting point: I currently do development for Dynamics Ax, Android and an occasional dabble with Wordpress and Python. Soon, I'll start a project involving setting up WP on Google Apps Engine. Everything is, and should continue to, run from the same PC (running Linux Mint). Issue: I'm afraid of botching/bogging down my setup due to tinkering/installing multiple runtimes/IDE's/SDK's/Services, so I was thinking of using multiple users, each purposed to handle the task at hand (web, Android etc) and making each user as inert as possible to one another. What I need to know is the following: Is this a good/feasible practice? The second closest thing to this using remote desktops connections, either to computers or to VM's, which I'd rather avoid. What about switching users? Can it be made seamless? Anything else I should know? Update and clarification regarding VM's and whatnot: The reason I wish to avoid resorting to VM's is that I dislike the performance impact and sluggishness associated with it. I also suspect it might add a layer of complexity I wish to avoid. This answer by Wyatt is interesting but I think it's only partly suited for requirements (web development for example). Also, in reference to the point made about system wide installs, there is a level compromise I should accept as experessed by this for example. This option suggested by 9000 is also enticing (more than VM's actually) and by no means do I intend to "Juggle" JVMs and whatnot, partly due to the reason mentioned before. Regarding complexity, I agree and would consider what was said, only from my experience I tend to pollute my work environment with SDKs and runtimes I tried and discarded, which would occasionally leave leftovers which cause issues throught the session. What I really want is a set of well defined, non virtualized sessions from which I can choose at my leisure and be mostly (to a reasonable extent) safe from affecting each session from the other. And what I'm really asking is if and how can this be done using user accounts.

  • How do I create an efficient long, pannable, sprite-animated scene in a Windows Store game?

    - by Groo
    I am creating my first Windows Store application in XAML, and I cannot seem to find a proper example for the requirements I have. The basic idea of the app is to have a large scrollable canvas which would lazily start animating visible parts of the view as soon as user stops panning over a certain content (with some audio played also): My original idea was to use a StackPanel to add a bunch of custom controls, each of which would then animate itself once visible (with a short delay), but I have a couple of concerns: If the entire canvas is ~50 screen widths wide, is it feasible to load all content at the beginning, or do I need to plan doing some lazy loading during scrolling? For example, when I select a certain region in the Bing Travel app, it seems to lazily load tiles as I scroll it towards the end. Since content is stretched 100% vertically, and these animations are vectorized to be resolution independent, I am not sure if XAML (CompositionTarget) will be able to handle this, or I have to go for DirectX (MonoGame or C++) to get rid of flicker. Even better, is there an example for Windows 8 which uses a 100% vertically sized GridView with custom animated controls inside?

  • Storing images in file system and returning URLs or virtually resizing and returning byte arrays?

    - by ismaelf
    I need to create a REST web service to manage user submitted images and displaying them all in a website. There are multiple websites that are going to use this service to manage and display images. The requirements are to have 5 pre-defined image sizes available. The 2 options I see are the following: The web service will create the 5 images, store them in the file system and and store the URL's in the database when the user submits the image. When the image is requested, the web service will return an array of URLs. I see this option to be a little hard on the hard drive. The estimates are 10,000 users per site, and lets say, 100 sites. The heavy processing will be done when the user submits the image and each image is going to be pulled from the File System. The web service will store just the image that the user submits in the file system and it's URL in the database. When the user request images, the web service will get the info from the DB, load the image on memory, create its 5 instances and return an object with 5 image arrays (I will probably cache the arrays). This option is harder on the processor and memory. The heavy processing will be done when the images get requested. A plus I see for option 2 is that it will give me the option to rewrite the URL of the image and make them site dependent (prettier) than having a image repository for all websites. But this is not a big deal. What do you think of these options? Do you have any other suggestions?

  • What's the benefit to learn Java programming?

    - by user30139
    I'm from the PHP world. Recently I'm trying to learn about Java. Because simply I'm a bit interested in Android development. Learning about Java gives more control about my cellphone. Say I could fine tune some applications to fit my personal requirements or even make my own ones. Still Java is a new world to me. I guess I'm already too comfortable with weak typed languages such as PHP. Honestly I think application development of no matter which kind wouldn't make too much difference. Because just as web development mostly framework based, what the developer do is to fill the blanks meaning to follow the protocols the given by the framework. Most of the code is still about business logic, that's what application development all about, right? The big difference seems to lie on the programming languages. Comparing to PHP, Java holds a whole package of constraints and practices. At this point, what are the benefits to learn programming in it?

  • A Myriad of Options

    - by Mark Hesse
    I am currently working with a customer that is close to outgrowing their Exadata X2-2 half rack in both compute and storage capacity.  The platform is used for one of their larger data warehouse applications and the move to Exadata almost two years ago has been a resounding success, forcing them to grow the platform sooner than anticipated. At a recent planning meeting, we started looking at the options for expansion and have developed five alternatives, all of which meet or exceed their growth requirements, yet have different pros and cons in terms of the impact to their production and test environments. The options include an in-rack upgrade to a full rack of Exadata using the recently released X3-2 platform (an option that even applies to an older V2 rack), multi-rack cabling the existing X2-2 to another full rack or half rack X2-2 (and utilizing both compute and storage capacity in the other rack), or simply adding a new X3-2 half rack (and taking advantage of the added compute and flash performance in the X3-2). While the decision is yet to be made, it had me thinking that one of the benefits of Exadata over a traditional database deployment is that when the time comes to expand the platform, there are a myriad of options.

  • How are the conceptual pairs Abstract/Concrete, Generic/Specific, and Complex/Simple related to one another in software architecture?

    - by tjb1982
    (= 2 (+ 1 1)) take the above. The requirement of the '=' predicate is that its arguments be comparable. Any two structures are comparable in this case, and so the contract/requirement is pretty generic. The '+' predicate requires that its arguments be numbers. That's more specific. (socket domain type protocol) the arguments here are much more specific (even though the arguments are still just numbers and the function itself returns a file descriptor, which is itself an int), but the arguments are more abstract, and the implementation is built up from other functions whose abstractions are less abstract, which are themselves built from less and less abstract abstractions. To the point where the requirements are something like move from one location to another, observe whether the switch at that location is on or off, turn the switch on or off, or leave it the same, etc. But are functions also less and less complex the less abstract they are? And is there a relationship between the number and range of arguments of a function and the complexity of its implementation, as you go from more abstract to less abstract, and vice versa? (= 2 (+ 1 1) 2r10) the '=' predicate is more generic than the '+' predicate, and thus could be more complex in its implementation. The '+' predicate's contract is less generic, and so could be less complex in its implementation. Is this even a little correct? What about the 'socket' function? Each of those arguments is a number of some kind. What they represent, though, is something more elaborate. It also returns a number (just like the others do), which is also a representation of something conceptually much more elaborate than a number. To boil it down, I'm asking if there is a relationship between the following dimensions, and why: Abstract/Concrete Complex/Simple Generic/Specific And more specifically, do different configurations of these dimensions have a specific, measurable impact on the number and range of the arguments (i.e., the contract) of a function?

  • How do I develop database-utilizing application in an agile/test-driven-development way?

    - by user39019
    I want to add databases (traditional client/server RDBMS's like Mysql/Postgresql as opposed to NoSQL, or embedded databases) to my toolbox as a developer. I've been using SQLite for simpler projects with only 1 client, but now I want to do more complicated things (ie, db-backed web development). I usually like following agile and/or test-driven-development principles. I generally code in Perl or Python. Questions: How do I test my code such that each run of the test suite starts with a 'pristine' state? Do I run a separate instance of the database server every test? Do I use a temporary database? How do I design my tables/schema so that it is flexible with respect to changing requirements? Do I start with an ORM for my language? Or do I stick to manually coding SQL? One thing I don't find appealing is having to change more than one thing (say, the CREATE TABLE statement and associated crud statements) for one change, b/c that's error prone. On the other hand, I expect ORM's to be a low slower and harder to debug than raw SQL. What is the general strategy for migrating data between one version of the program and a newer one? Do I carefully write ALTER TABLE statements between each version, or do I dump the data and import fresh in the new version?

  • Ubuntu (i386 - 32bit) 12.04 LTS [DESKTOP] - Freezes During Preparing to Install

    - by Michael Ecklund
    I know this is for the Desktop version of Ubuntu, but I definitely plan on installing the server as well. I just want a GUI to manage my server. Here is what I have done: Placed Ubuntu i386/32bit 12.04 LTS [DESKTOP] disc in the disc tray. The disc loads fine. Clicked install Ubuntu. Without checking the download updates while installing or install this third-party software. Clicked continue. Mouse cursor turns to spinning circle and remains a spinning circle while the screen freezes its place at "Preparing to install Ubuntu". I tried not checking any of the boxes and clicking continue. I tried checking Download updates while installing. I tried checking Install this third-party software. I tried checking BOTH Download updates while installing AND Install this third-party software. Does anyone else face this very same issue? Is there a workaround for this problem? Do I need to use a lower version of Ubuntu? If so, which version do you recommend for my system specifications? My system meets the system requirements. Here are my exact system specifications. (Custom modifications: 320GBx2 HDD && 256MB AGP GFX card && 1GBx2 RAM)

  • Iterative and Incremental Principle Series 5: Conclusion

    - by llowitz
    Thank you for joining me in the final segment in the Iterative and Incremental series.  During yesterday’s segment, I discussed Iteration Planning, and specifically how I planned my daily exercise (iteration) each morning by assessing multiple factors, while following my overall Implementation plan. As I mentioned in yesterday’s blog, regardless of the type of exercise or how many increment sets I decide to complete each day, I apply the 6 minute interval sets and a timebox approach.  When the 6 minutes are up, I stop the interval, even if I have more to give, saving the extra energy to apply to my next interval set.   Timeboxes are used to manage iterations.  Once the pre-determined iteration duration is reached – whether it is 2 weeks or 6 weeks or somewhere in between-- the iteration is complete.  Iteration group items (requirements) not fully addressed, in relation to the iteration goal, are addressed in the next iteration.  This approach helps eliminate the “rolling deadline” and better allows the project manager to assess the project progress earlier and more frequently than in traditional approaches. Not only do smaller, more frequent milestones allow project managers to better assess potential schedule risks and slips, but process improvement is encouraged.  Even in my simple example, I learned, after a few interval sets, not to sprint uphill!  Now I plan my route more efficiently to ensure that I sprint on a level surface to reduce of the risk of not completing my increment.  Project managers have often told me that they used an iterative and incremental approach long before OUM.   An effective project manager naturally organizes project work consistent with this principle, but a key benefit of OUM is that it formalizes this approach so it happens by design rather than by chance.    I hope this series has encouraged you to think about additional ways you can incorporate the iterative and incremental principle into your daily and project life.  I further hope that you will share your thoughts and experiences with the rest of us.

  • Hosting and scaling a Facebook application in the cloud? [closed]

    - by DhruvPathak
    Possible Duplicate: How to find web hosting that meets my requirements? We would be building a Facebook application in Django (Python), but still not sure of where to host it economically, and with a good provision to scale in case the app gets viral. Some details about the app: Would be HTML based like a website,using django as a framework. 100K is the number of expected pageviews in a day, if the app is viral. The users will not generate any media content, only some database data will be generated by them. It would be great if someone with more experience can guide on following points: A) Hosting on Google app engine or Amazon EC2 or some other cloud like RackSpace : Preferable points found in AppEngine were ease of deployment, cost effectiveness and easy scaling. For EC2: Full hold of the virtual machine,Amazon NoSQL and RDMBS database services in case we decide to use them. B) Does backend technology affect monthly cost? eg. would CPU and memory usage difference of Django over , for example , PHP framework like CodeIgnitor really make remarkable difference in running costs. (Here is the article that triggered this thought process : http://journal.dedasys.com/2010/01/12/rough-estimates-of-the-dollar-cost-of-scaling-web-platforms-part-i#comments) C) Does something like Heroku , which provides additional services over Amazon EC2, prove to be better than raw cloud management? It is not that we are trying for premature scaling, we just want to have a good start so that we are ready to handle unpredicted growth and scale.

  • Network(ing) to the Limit

    - by Oracle OpenWorld Blog Team
     By Karen Shamban While Oracle OpenWorld attendees are networking, there's an Oracle Global IT team that builds and maintains the massive networks that help run the show. The objective? To keep things running as seamlessly and smoothly as possible, constantly evaluate priorities, mitigate risk, and be ready for whatever might happen -- because things do happen when there are 50,000 plus attendees, tens of thousands of devices, unexpected requirements, and a constant flow of up-to-the-minute information. Here's just some of what it takes to keep the conference going, network style: 100 Oracle network, voice, and desktop engineers; security, risk management, and other IT experts, who come in from 17 countries  1000+ network switches 300+ miles of copper and fiber 485 wireless access points 2,500 wired laptops 300 VoIP phones And just where are all these networks and devices deployed? This is what the team had to build and manage: Moscone North, South, and West, including: The keynote hall Oracle DEMOgrounds in the Exhibition Halls Hundreds of session rooms Connection Centers, Social Avenue, Lounges Registration The Howard Street Tent and Taylor Street Cafe tented venues Oracle Square (Union Square) Yerba Buena Gardens Masonic Auditorium Sessions and demos at 8 hotel venues That's a whole lot of networking going on. And here's the kicker: the team has only 4 days to bring get it all up and running across these many venues, and exactly 12 hours to take it all down once the show ends. The Global IT team puts in the equivalent of 152 24-hour days for set-up, 227 24-hour days of support during the conferences, and then tears it all down in about 20 24-hour days. And in case you were wondering, the planning for next year's Oracle OpenWorld starts ... next week. No rest for the weary.  Now THAT's networking!  So hats off to the Global IT team -- the job ain't easy, but somebody's got to do it, and they do it remarkably well.

  • how to deal with controller mutations

    - by Milovan Zogovic
    During development process, things are constantly changing (especially in early phases). Requirements change, UI changes, everything changes. Pages that clearly belonged to specific controller, mutated to something completely different in the future. For example. Lets say that we have website for managing Projects. One page of the website was dedicated to managing existing, and inviting new members of specific project. Naturally, I created members controller nested under projects which had proper responsibility. Later in the development, it turned out that it was the only page that was "configuring the project" in some way, so additional functionalities were added to it: editing project description setting project as a default ... In other words, this page changed its primary responsibility from managing project members to managing project itself. Ideally, this page should be moved to "edit" action of "projects" controller. That would mean that all request and controller specs need to refactored too. Is it worth the effort? Should it be done? Personally, I am really starting to dislike the 1-1 relationship between views and controllers. Its common situation that we have 1 page (view) that handles 2 or more different resources. I think we should have views completely decoupled from controllers, but rails is giving us hard time to achieve this. I know that AJAX can be used to solve this issue, but I consider it an improvisation. Is there some other kind of architecture (other than MVC) that decouples views from controllers?

  • What's the simplest way to provide a portable, locally running webservice server application?

    - by derFunk
    We have a bigger website running that offers a JsonRpc web service. For offline demonstration purposes I want to realize a portable, locally running webserver with a minimalistic feature replication of the live webservice, and bundle this together with Html files which do Ajax requests to it. This local server executable should have as little dependencies as possible. It's gonna be run and presented by non-devs on non-dev Windows machines, so I would prefer having a simple executable plus the service code - whereas language doesn't matter as long as it is .NET, PHP or Java. I'll need a small database behind which probably will be Sqlite. It's important to say that for some reasons we cannot use the original web service code, but we have to rewrite it new for the local demo server, this is why I want to put minimal effort in the local server tech. An installer for distribution is not mandatory, it's okay to have a zip file with an executable in it which starts up the local webserver. What would you recommend realizing these requirements? I've done some research already, but would love to here your opinions and get some pointers!

  • How can I justify a technology over another? (Java over .NET)

    - by user674887
    We are working in a Java/.NET company and my team and I are planning a project for a client. One of the requirements is that the project has to be done in .NET I've asked about this requirement, and the client said that it doesn't matter, and that if I have a good reason we can use other technology. But, I have to justify the decision. As a Project Manager / Analyst I'm interested in making the project in Java because: The team knows java much better, regarding the language and frameworks I don't know anything about .NET technology (and maybe we could make bad decisions thinking in a Java way to do things) There are other people in company that have more skills in .NET but they have other projects with more priority. For experience, I'm sure that if we use Java, the project will have much more quality. But this arguments could be weak from the client perspective. How can I justify making the project in Java? EDIT: I'm not asking if one technology is better than other. "It's not a technology war" question.

  • Drupal site Instant Messaging [migrated]

    - by pthurmond
    I am trying to find a module or a standalone solution that I can turn into a module that will allow me to have an instant messaging system like Facebook does on a Drupal site that I am working on. I have never setup a chat system before. My particular requirements are rather stringent. It needs to be a solution where we host the chatting server (if one is needed separate from the website itself). It must use the site's login state (can't use an external system at all, that means no GTalk, Yahoo IM, or AIM). It also must be able to handle up to 1,000 users at any given time. I have looked through the Drupal community and I tried the DXMPP module, but it requires Jquery UI 1.8 and that doesn't work with all of the other things that my site uses (such as Homebox). We do have a Jabber server already setup and ready to go. Does anyone have any thoughts or options here? Thanks! EDIT: We are using Drupal 6.

  • Alternatives to PHP [closed]

    - by kaz
    We are starting a project, which goal is to create new frontend interface to our product. Old version was created in PHP, very poorly written. We are choosing the language and frameworks that we want to use in new version. Requirements: New interface will be communicating with API. Application will not have it's own database. We don't have a big team, 3 max programmers for entire project. The main programmers are PHP veterans and knows some other technologies (Rails, C, C++, some Java) but not in professional level. But overall they are good and experienced programmers. So: We want to find a good alternative to PHP. I like Rails very much, but whole ActiveRecord model will be useless, when using application API. Java needs a lot of configuration and someone who is expert in Java to properly run this project. Also, in Java there are a lot of big and complicated enterprise frameworks - not very good for 2-3 programmers team. Python - I don't know Python and don't know good and experienced programmers who knows PY - but it's not so complicated and big as Java and maybe in long period it's good alternative for PHP. What are your thoughts?

  • iPhone app with tab bar and navigation bar as peers

    - by Mac
    I'm trying to write an application that uses a navigation bar and tab bar in what (I'm gathering) is an unusual manner. Basically, I've got several "pages" ("home", "settings", etc) that each have their own tab. I'd also like to have it so that the "home" page is the root view of the navigation bar, and the other pages are the second-level views of the navigation bar. That is, I should be able to navigate to any page by clicking the appropriate tab bar item, and should be able to navigate to the home page from any other page by clicking the navigation bar's back button. Currently, I have a UINavigationBar (through a UINavigationController) and a UITabBar (through a UITabController) as children of a UIView. The various pages' view controllers are set as the tab controller's viewControllers property, and the home page's controller is also set as the navigation controller's root view. Each page view's tag is set to its index in the tab control. I have the following logic in the tab controller's didSelectViewController delegate method: - (void) tabBarController:(UITabBarController*) tabBarController didSelectViewController:(UIViewController*) viewController { if ([navController.viewControllers count] > 1) [navController popViewControllerAnimated:NO]; [navController pushViewController:viewController animated:YES]; } Also, in the navigation controller's didShowViewController delegate method, I have the following code: - (void) navigationController:(UINavigationController *) navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated { tabController.selectedIndex = viewController.view.tag; } The problem that's occurring is that when I run this, the navigation bar, tab bar and home page all display ok, but the tab bar will not respond to input - I cannot select a different tab. I gather it's more usual to have the tab bar as the child of the navigation control, or vice versa. This doesn't seem to fit my approach, because I don't want to have to individually create the subordinate control each time a change occurs in the parent control - eg: recreate tab bar each time the navigation bar changes. Does anyone have suggestions as to what's wrong and how to fix it? I'm probably missing something obvious, but whatever it is I can't seem to find it. Thanks! EDIT: I'm guessing it has something to do with both controller's trying to have ownership of the page controller, but I can't for the life of me figure out a way around it.

  • _heapwalk reports _HEAPBADNODE, causes breakpoint or loops endlessly

    - by Stefan Hubert
    I use _heapwalk to gather statistics about the Process' standard heap. Under certain circumstances i observe unexpected behaviours like: _HEAPBADNODE is returned some breakpoint is triggered inside _heapwalk, telling me the heap might got corrupted access violation inside _heapWalk. I saw different behaviours on different Computers. On one Windows XP 32 bit machine everything looked fine, whereas on two Windows XP 64 bit machines i saw the mentioned symptoms. I saw this behaviour only if LowFragmentationHeap was enabled. I played around a bit. I walked the heap several times right one after another inside my program. First time doing nothing in between the subsequent calls to _heapWalk (everything fine). Then again, this time doing some stuff (for gathering statistics) in between two subsequent calls to _heapWalk. Depending upon what I did there, I sometimes got the described symptoms. Here finally a question: What exactly is safe and what is not safe to do in between two subsequent calls to _heapWalk during a complete heap walk run? Naturally, i shall not manipulate the heap. Therefore i doublechecked that i don't call new and delete. However, my observation is that function calls with some parameter passing causes my heap walk run to fail already. I subsequently added function calls and increasing number of parameters passed to these. My feeling was two function calls with two paramters being passed did not work anymore. However I would like to know why. Any ideas why this does not happen on some machines? Any ideas why this only happens if LowFragmentationHeap is enabled? Sample Code finally: #include <malloc.h> void staticMethodB( int a, int b ) { } void staticMethodA( int a, int b, int c) { staticMethodB( 3, 6); return; } ... _HEAPINFO hinfo; hinfo._pentry = NULL; while( ( heapstatus = _heapwalk( &hinfo ) ) == _HEAPOK ) { //doing nothing here works fine //however if i call functions here with parameters, this causes //_HEAPBADNODE or something else staticMethodA( 3,4,5); } switch( heapstatus ) { ... case _HEAPBADNODE: assert( false ); /*ERROR - bad node in heap */ break; ...

  • JavaScript: How to get text from all descendents of an element, disregarding scripts?

    - by Bungle
    My current project involves gathering text content from an element and all of its descendents, based on a provided selector. For example, when supplied the selector #content and run against this HTML: <div id="content"> <p>This is some text.</p> <script type="text/javascript"> var test = true; </script> <p>This is some more text.</p> </div> my script would return (after a little whitespace cleanup): This is some text. var test = true; This is some more text. However, I need to disregard text nodes that occur within <script> elements. This is an excerpt of my current code: // get text content of all matching elements for (x = 0; x < selectors.length; x++) { matches = Sizzle(selectors[x], document); for (y = 0; y < matches.length; y++) { match = matches[y]; if (match.innerText) { // IE content += match.innerText + ' '; } else if (match.textContent) { // other browsers content += match.textContent + ' '; } } } It's a bit overly simplistic in that it just returns all text nodes within the element (and its descendants) that matches the provided selector. The solution I'm looking for would return all text nodes except for those that fall within script elements. It doesn't need to be especially high-performance, but I do need it to ultimately be cross-browser compatible. I'm assuming that I'll need to somehow loop through all children of the element that matches the selector and accumulate all text nodes other than ones within <script> elements; it doesn't look like there's any way to identify JavaScript once it's already rolled into the string accumulated from all of the text nodes. I can't use jQuery (for performance/bandwidth reasons), although you may have noticed that I do use its Sizzle selector engine, so jQuery's selector logic is available. Thanks in advance for any help!

  • bmp image header doubts

    - by vikramtheone
    Hi Guys, I'm doing a project where I have to make use of the pixel information of a bmp image. So, I'm gathering the image information by reading the header information of the input .bmp image. I'm quite successful with everything but one thing bothers me, can any one here clarify it? The header information of my .bmp image is as follows (My test image is very tiny and gray scale)- BMP File header File size 1210 Offset information 1078 BMP Information header Image Header Size 40 Image Size 132 Image width 9 Image height 11 Image bits_p_p 8 So, from the .bmp header I see that the image size is 132 (bytes) but when I multiply the width and height it is only 99, how is such a thing possible? I'm confident with 132 bytes because when I subtract the Offset value with the File Size value, I get 132(1210 - 1078 = 132) and also when I manually count the number of bytes (In a HEX editor) from the point 1078 or 436h (End of the offset field), there are exactly 132 bytes of pixel information. So, why is there a disparity between the size filed and the (width x height)? My future implementations are dependent on the image width and height information and not on Image size information. So, I have to understand thoroughly whats going on here. My understanding of the header should be clearly wrong... I guess!!! Help!!! Regards Vikram My bmp structures are a as follows - typedef struct bmpfile_magic { short magic; }BMP_MAGIC_NUMBER; typedef struct bmpfile_header { uint32_t filesz; uint16_t creator1; uint16_t creator2; uint32_t bmp_offset; }BMP_FILE_HEADER; typedef struct { uint32_t header_sz; uint32_t width; uint32_t height; uint16_t nplanes; uint16_t bitspp; uint32_t compress_type; uint32_t bmp_bytesz; uint32_t hres; uint32_t vres; uint32_t ncolors; uint32_t nimpcolors; } BMP_INFO_HEADER;

  • Ninject with Object Initializers and LINQ

    - by Alexander Kahoun
    I'm new to Ninject so what I'm trying may not even be possible but I wanted to ask. I free-handed the below so there may be typos. Let's say I have an interface: public interface IPerson { string FirstName { get; set; } string LastName { get; set;} string GetFullName(); } And a concrete: public class Person : IPerson { public string FirstName { get; set; } public string LastName { get; set; } public string GetFullName() { return String.Concat(FirstName, " ", LastName); } } What I'm used to doing is something like this when I'm retrieving data from arrays or xml: public IEnumerable<IPerson> GetPeople(string xml) { XElement persons = XElement.Parse(xml); IEnumerable<IPerson> people = ( from person in persons.Descendants("person") select new Person { FirstName = person.Attribute("FName").Value, LastName = person.Attribute("LName").Value }).ToList(); return people; } I don't want to tightly couple the concrete to the interface in this manner. I haven't been able to find any information in regards to using Ninject with LINQ to Objects or with object initializers. I may be looking in the wrong places, but I've been searching for a day now with no luck at all. I was contemplating putting the kernel into an singleton instance and seeing if that would work, but I'm not sure that it will plus I've heard that passing your kernel around is a bad thing. I'm trying to implement this in a class library currently. If this is not possible, does anyone have any examples or suggestions as to what the best practice is in this case? Thanks in advance for the help. EDIT: Based on some of the answers I feel I should clarify. Yes, the example above appears short lived but it was simply an example of one piece that I was trying to do. Let's give a bigger picture. Say instead of XML I am gathering all my data through a 3rd party web service and I'm creating an interface for it, the data could be a defined object in the wsdl or it could sometimes be an xml string. IPerson could be used for both the Person object and a User object. I will be doing this inside of a separate class library, because it needs to be portable and will be used in other projects, and handing it to an MVC3 Web Application and the objects will be used in javascript as well. I appreciate all the input so far.
