• Is this a pattern? Should it be?

  - by Arkadiy

  The following is more of a statement than a question - it describes something that may be a pattern. The question is: is this a known pattern? Or, if it's not, should it be? I've had a situation where I had to iterate over two dissimilar multi-layer data structures and copy information from one to the other. Depending on particular use case, I had around eight different kinds of layers, combined in about eight different combinations: A-B-C B-C A-C D-E A-D-E and so on After a few unsuccessful attempts to factor out the repetition of per-layer iteration code, I realized that the key difficulty in this refactoring was the fact that the bottom level needed access to data gathered at higher levels. To explicitly accommodate this requirement, I introduced IterationContext class with a number of get() and set() methods for accumulating the necessary information. In the end, I had the following class structure: class Iterator { virtual void iterateOver(const Structure &dataStructure1, IterationContext &ctx) const = 0; }; class RecursingIterator : public Iterator { RecursingIterator(const Iterator &below); }; class IterateOverA : public RecursingIterator { virtual void iterateOver(const Structure &dataStructure1, IterationContext &ctx) const { // Iterate over members in dataStructure1 // locate corresponding item in dataStructure2 (passed via context) // and set it in the context // invoke the sub-iterator }; class IterateOverB : public RecursingIterator { virtual void iterateOver(const Structure &dataStructure1, IterationContext &ctx) const { // iterate over members dataStructure2 (form context) // set dataStructure2's item in the context // locate corresponding item in dataStructure2 (passed via context) // invoke the sub-iterator }; void main() { class FinalCopy : public Iterator { virtual void iterateOver(const Structure &dataStructure1, IterationContext &ctx) const { // copy data from structure 1 to structure 2 in the context, // using some data from higher levels as needed } } IterationContext ctx(dateStructure2); IterateOverA(IterateOverB(FinalCopy())).iterate(dataStructure1, ctx); } It so happens that dataStructure1 is a uniform data structure, similar to XML DOM in that respect, while dataStructure2 is a legacy data structure made of various structs and arrays. This allows me to pass dataStructure1 outside of the context for convenience. In general, either side of the iteration or both sides may be passed via context, as convenient. The key situation points are: complicated code that needs to be invoked in "layers", with multiple combinations of layer types possible at the bottom layer, the information from top layers needs to be visible. The key implementation points are: use of context class to access the data from all levels of iteration complicated iteration code encapsulated in implementation of pure virtual function two interfaces - one aware of underlying iterator, one not aware of it. use of const & to simplify the usage syntax.

• Are You Meeting Social Customer Service Expectations?

  - by Mike Stiles

  Whether it’s B2B or B2C, one sure path to repeat business is making sure your buyer has a memorably pleasant and successful customer service experience with you. If they get that kind of treatment consistently, that’s called a relationship. And those aren’t broken easily. Social customer service, driven by integrated SRM (social relationship management) technology, is the venue that can effectively connect customers not only to the brand, but to other customers. Positive experiences, once administered, don’t just rest with the recipient. They’re published in the form of public raves and peer-to-peer recommendation, a force far more actionable than push advertising. What’s more, your customers have come to expect access to you and satisfaction from you using social. An NM Incite study shows 83% of Twitter users and 71% of Facebook users expect to get an answer from brands the same day they post to them on their social assets. To make sure you’re responding, you’ve got to have a tech platform that’s set up to moderate and alert so you’ll know ASAP a customer needs help. The more integrated your social enterprise is, the faster you can not only respond, but respond with the answer they’re looking for, because your system is connected to the internal resources that can surface the answer or put wheels in motion to rectify the situation in the shortest amount of time possible. But if you go to the necessary lengths to make sure your customers feel valued and important, will they really reward you? The study says 71% of consumers who got quick and effective responses from companies they contacted via social were more likely to recommend the brand to their friends and followers. So yes, sweeping people off their feet pays big dividends in terms of word-of-mouth marketing. But you should be keenly aware of the reverse side of that coin. Give people a negative experience, either in real world or virtual customer service, and that message is highly likely to get amplified through social channels faster and louder. Only 36% of the NM Incite study’s respondents reported that their problems were solved quickly and effectively. 36%? That’s hardly an impressive number. It gets worse. 10% never got so much as a response - at all. Going back to the relationship analogy, companies that are this deep in the ditch where customer service is concerned are making their girl or boyfriends really easy for a competitor to steal. Given the technology tools and data available right now for having an intimate knowledge of the customer, what products they’ve purchased, likely problems with those products, effective resolutions to those problems, and follow-up communication to gauge satisfaction, there are fewer excuses than ever for making the lifeblood of your business feel like you couldn’t care less. @mikestiles

• Summary of our Recent Pull Request Enhancements on CodePlex

  Over the past several weeks, we’ve been incrementally rolling out a bunch of enhancements around our pull request workflow for Git and Mercurial projects. Our goal is to make contributing to open source projects a simple and rewarding experience, and we’ll continue to invest in this area. Here’s a summary of the changes so far, in case you’ve missed them. As always, if you have any feedback, please let us know, whether on our ideas page or via Twitter. Support for branches You can now pick the source and destination branches for your pull request, whether you’re sending one from your fork, or using it within a project to collaborate with your other trusted contributors. A redesigned creation experience Our old pull request creation form was rather lacking. It asked for a title and comment in a small modal dialog, but that was about it. We knew we could do better, so we rethought the experience. Now, when you create a pull request, you’re taken to a new page that let’s you select the source and destination, and gives you information on the diffs and commits that you’re sending, so you can confirm that you’re sending the right set of changes. Inline code snippets in discussion If users comment on code in your pull request, we now display a preview of the snippet of relevant code inline with their comment on the discussion. Subsequent replies on that line are combined in a single thread to preserve your context. No more clicking and hunting to find where the comments are. And you can add another inline comment right from the discussion area. Comment notifications You can now elect receive an e-mail notification if a user comments on your pull request. If it’s on a line of code, we’ll display the relevant code snippet in the e-mail. Redesigned diff viewer Our old diff viewer hadn’t been touched in a while, and was in need of an update. We started with a visual facelift to use standard red/green colors for additions/deletions and remove the noisy “dots” that represented spaces and that littered the diff viewer. Based on feedback that the viewable region for diffs was too small, especially for smaller screen resolutions, we revamped the way the viewport for the code is sized, and now expand it to fill the majority of the browser height when scrolling down. The set of improvements we implemented here also apply anywhere diffs are viewed, not just for pull requests.

• [EF + Oracle] Inserting Data (1/2)

  - by JTorrecilla

  Prologue Following EF series (I ,II y III) in this chapter we will see how to create DB record from EF. Inserting Data Like we indicated in the 2º post: “One Entity matches with a DB record, and one property match with a Table Column”. To start, we need to create an object from one of the Entities: 1: EMPLEADOS empleado = new EMPLEADOS(); Also like, I told previously, Exists the possibility to use the Static Function defined by VS for each Entity: Once we have created the object, we can Access to it properties to fill like a common class:   1: empleado.NOMBRE = "Javier Torrecilla";   After finish of fill our Entity properties, it must be needed to add the object to the appropriate ObjectSet in the ObjectContext: 1: enti.EMPLEADOS.AddObject(empleado); or 1: enti.AddToEMPLEADOS(empleado); Both methods will do the same action, create an insert statement. Have we finished? No. Any Entity has a property called “EntityState”. This prop is an Enum from “EntityState”, which has the following: Detached: the Entity is created, but not added to the Context. Unchanged: There is no pending changes in the Entity. Added: The entity is added to the ObjectSet, but it is not yet sent to the DB. Deleted: The object is deleted form the ObjectSet, but not yet from the DB. Modified: There is Pending Changes to confirm. Let’s see, the several values of the property during the Creation steps: 1. While the Object is created and we are filling the props: EntityState.Detached; 2. After adding to the ObjectSet: EntityState.Added. This not indicated that the record is in the DB 3. Saving the Data: To sabe the data in the DB, we are going to call “SaveChanges” method of the Object Context. After invoke it, the property will be EntityState.Unchanged.   What does SaveChanges Method? This function will synchronize and send all pending changes to DB. It will add, modify or delete all Entities, whose EntityState property, is setted to Added, Deleted or Modified. After finishing, all added or modified entities will be change the State to “Unchanged”, and deleted Entities must take the “Detached” state.

• The difference

  So with the CTP tools available, weve been building a few apps, just to get a feel for the tools and whats supported in the framework.  Whats been great is that everything is fairly familiar and consistent, largely to do with the .net framework and Microsofts focus on providing good tools.  Weve produced mobile applications, mostly in concept form, for Windows Phone Classic, iPhone and Android but never so quickly and not of such high quality and visual impression.  I attribute some of this obviously to our familiarity to the Microsoft platform and tools.  Though when you look at the designs our team has produced, it becomes clear that this is not just another mobile application container.                                                            The Metro design language implores content prominence with fluid motion and transitions, with a crisp font and easily organized features and services placement.  In addition to a purposeful right edge tease, where the intent is for users to discover new premium content and services.   The concept that enables this is called hubs, building application with hubs changes your thinking from a single mobile application task, to thinking creatively about a mobile experience. Its engaging to think of the other brands and industry verticals that will take advantage of this core feature.  Combine this with Windows Phone 7 live tiles, more on that later, and you have a recipe for a solid mobile services platform.                                                              This so much more fun and liberating than my icon on a gridDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Send raw data to USB parallel port after upgrading to 11.10 oneiric

  - by zaphod

  I have a laser cutter connected via a generic USB to parallel adapter. The laser cutter speaks HPGL, as it happens, but since this is a laser cutter and not a plotter, I usually want to generate the HPGL myself, since I care about the ordering, speed, and direction of cuts and so on. In previous versions of Ubuntu, I was able to print to the cutter by copying an HPGL file directly to the corresponding USB "lp" device. For example: cp foo.plt /dev/usblp1 Well, I just upgraded to Ubuntu 11.10 oneiric, and I can't find any "lp" devices in /dev anymore. D'oh! What's the preferred way to send raw data to a parallel port in Ubuntu? I've tried System Settings Printing + Add, hoping that I might be able to associate my device with some kind of "raw printer" driver and print to it with a command like lp -d LaserCutter foo.plt But my USB to parallel adapter doesn't seem to show up in the list. What I do see are my HP Color LaserJet, two USB-to-serial adapters, "Enter URI", and "Network Printer". Meanwhile, over in /dev, I do see /dev/ttyUSB0 and /dev/ttyUSB1 devices for the 2 USB-to-serial adapters. I don't see anything obvious corresponding to the HP printer (which was /dev/usblp0 prior to the upgrade), except for generic USB stuff. For example, sudo find /dev | grep lp produces no output. I do seem to be able to print to the HP printer just fine, though. The printer setup GUI gives it a device URI starting with "hp:" which isn't much help for the parallel adapter. The CUPS administrator's guide makes it sound like I might need to feed it a device URI of the form parallel:/dev/SOMETHING, but of course if I had a /dev/SOMETHING I'd probably just go on writing to it directly. Here's what dmesg says after I disconnect and reconnect the device from the USB port: [ 924.722906] usb 1-1.1.4: USB disconnect, device number 7 [ 959.993002] usb 1-1.1.4: new full speed USB device number 8 using ehci_hcd And here's how it shows up in lsusb -v: Bus 001 Device 008: ID 1a86:7584 QinHeng Electronics CH340S Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.10 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 8 idVendor 0x1a86 QinHeng Electronics idProduct 0x7584 CH340S bcdDevice 2.52 iManufacturer 0 iProduct 2 USB2.0-Print iSerial 0 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 32 bNumInterfaces 1 bConfigurationValue 1 iConfiguration 0 bmAttributes 0x80 (Bus Powered) MaxPower 96mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 2 bInterfaceClass 7 Printer bInterfaceSubClass 1 Printer bInterfaceProtocol 2 Bidirectional iInterface 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x82 EP 2 IN bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0020 1x 32 bytes bInterval 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x02 EP 2 OUT bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0020 1x 32 bytes bInterval 0 Device Status: 0x0000 (Bus Powered)

• How to properly document functionality in an agile project?

  - by RoboShop

  So recently, we've just finished the first phase of our project. We used agile with fortnightly sprints. And whilst the application turned out well, we're now turning our eyes on some of the maintenance tasks. One maintenance task is that all of our documentation appears in the form of specs. These specs describe 1 or more stories and generally are a body of work which a few devs could knock over in a week. For development, that works really well - every two weeks, the devs get handed a spec and it's a nice discrete chunk of work that they can just do. From a documentation point of view, this has become a mess. The problem with writing specs that are focused on delivering just-in-time requirements to developers is we haven't placed much emphasis on the big picture. Specs come from all different angles - it could be describing a standard function, it could describing parts of a workflow, it could be describing a particular screen... And now, we have business rules about our application scattered across 120 documents. Looking for any document for a particular business rule or function in particular is quite hard because you don't know which document has this information, and making a change request is equally hard because once again, we are unsure about which spec to make the change. So we have maybe a couple of weeks of lull before it's back to specing out functionality for the next phase but in this time, I'd like to re-visit our processes. I think the way we have worked so far in terms of delivering fortnightly specs works well. But we also need a way to manage our documentation so that our business rules for a given function / workflow are easy to locate / change. I have two ideas. One is we compile all of our specs into a series of master specs broken by a few broad functional areas. The specs describe the sprint, the master spec describe the system. The only problem I can see is 1) Our existing 120 specs are not all neatly defined into broad functional areas. Some will require breaking up, merging etc. which will take a lot of time. 2) We'll be writing specs and updating master specs in each new sprint. Seems like double the work, and then do the devs look at the spec or the master spec? My other suggestion is to concede that our documentation is too big of a mess, and manage that mess going forward. So we go through each spec, assign like keywords to it, and then when we want to search for a function, we search for that keyword. Problems I can see 1) Still the problem of business rules scattered everywhere, keywords just make it easier to find it. anyway, if anyone has any decent ideas or any experience to share about how best to manage documentation, would really appreciate it.

• The long road to bug-free software

  - by Tony Davis

  The past decade has seen a burgeoning interest in functional programming languages such as Haskell or, in the Microsoft world, F#. Though still on the periphery of mainstream programming, functional programming concepts are gradually seeping into the imperative C# language (for example, Lambda expressions have their root in functional programming). One of the more interesting concepts from functional programming languages is the use of formal methods, the lofty ideal behind which is bug-free software. The idea is that we write a specification that describes exactly how our function (say) should behave. We then prove that our function conforms to it, and in doing so have proved beyond any doubt that it is free from bugs. All programmers already use one form of specification, specifically their programming language's type system. If a value has a specific type then, in a type-safe language, the compiler guarantees that value cannot be an instance of a different type. Many extensions to existing type systems, such as generics in Java and .NET, extend the range of programs that can be type-checked. Unfortunately, type systems can only prevent some bugs. To take a classic problem of retrieving an index value from an array, since the type system doesn't specify the length of the array, the compiler has no way of knowing that a request for the "value of index 4" from an array of only two elements is "unsafe". We restore safety via exception handling, but the ideal type system will prevent us from doing anything that is unsafe in the first place and this is where we start to borrow ideas from a language such as Haskell, with its concept of "dependent types". If the type of an array includes its length, we can ensure that any index accesses into the array are valid. The problem is that we now need to carry around the length of arrays and the values of indices throughout our code so that it can be type-checked. In general, writing the specification to prove a positive property, even for a problem very amenable to specification, such as a simple sorting algorithm, turns out to be very hard and the specification will be different for every program. Extend this to writing a specification for, say, Microsoft Word and we can see that the specification would end up being no simpler, and therefore no less buggy, than the implementation. Fortunately, it is easier to write a specification that proves that a program doesn't have certain, specific and undesirable properties, such as infinite loops or accesses to the wrong bit of memory. If we can write the specifications to prove that a program is immune to such problems, we could reuse them in many places. The problem is the lack of specification "provers" that can do this without a lot of manual intervention (i.e. hints from the programmer). All this might feel a very long way off, but computing power and our understanding of the theory of "provers" advances quickly, and Microsoft is doing some of it already. Via their Terminator research project they have started to prove that their device drivers will always terminate, and in so doing have suddenly eliminated a vast range of possible bugs. This is a huge step forward from saying, "we've tested it lots and it seems fine". What do you think? What might be good targets for specification and verification? SQL could be one: the cost of a bug in SQL Server is quite high given how many important systems rely on it, so there's a good incentive to eliminate bugs, even at high initial cost. [Many thanks to Mike Williamson for guidance and useful conversations during the writing of this piece] Cheers, Tony.

• Ad-hoc reporting similar to Microstrategy/Pentaho - is OLAP really the only choice (is OLAP even sufficient)?

  - by TheBeefMightBeTough

  So I'm getting ready to develop an API in Java that will provide all dimensions, metrics, hierarchies, etc to a user such that they can pick and choose what they want (say, e.g., dimensions of Location (a store) and Weekly, and the metric Product Sales $), provide their choices to the api, and have it spit out an object that contains the answer to their question (the object would probably be a set of cells). I don't even believe there will be much drill up/down. The data warehouse the APIwill interface with is in a standard form (FACT tables, dimensions, star schema format). My question is, is an OLAP framework such as Mondrian the only way to achieve something akin to ad-hoc reporting? I can envisage a really large Cube (or VirtualCube) that contains most of the dimensions and metrics the user could ever want, which would give the illusion of ad-hoc reporting. The problem is that there is a ton of setup to do (so much XML) to get the framework to work with the data. Further it requires specific knowledge, such as MDX, and even moreso learning the framework peculiars (Mondrian API). Finally, I am not positive it will scale much better than simply making queries against a SQL database. OLAP to me feels like very old technology. Is performance really an issue anymore? The alternative I can think of would be dynamic SQL. If the existing tables in the data warehouse conform to a naming scheme (FACT_, DIM_, etc), or if a very simple config file/ database table containing config information existed that stored which tables are fact tables, which are dimensions, and what metrics are available, then couldn't the api read from that and assembly the appropriate sql query? Would this necessarily be harder than learning MDX, Mondrian (or another OLAP framework), and creating all the cubes? In general, I feel that OLAP is at the same time too powerful (supports drill up/down, complex functions) and outdated and am reluctant to base my architecture on it. However, I am unsure if the alternative(s), such as rolling my own ad-hoc reporting framework using dynamic SQL would remove any complexity while still fulfilling requirements, both functional and non-functional (e.g., scalability; some FACT tables have many millions of rows). I also wonder about other techniques (e.g., hive). Has anyone here tried to do ad-hoc reporting? Any advice? I expect this project to take a pretty long time (3 months min, but probably longer), so I just do not want to commit to an architecture without being absolutely sure of its pros and cons. Thanks so much.

• How to get the height of an image and apply that height to a div? [migrated]

  - by Mick79

  I am building a mobile web app and I'm using jquerytools slider on it. i want te slider to show (in proper ratio) across all mobile devices so width of the images is 100% and height is auto in css. However as all the elements are floated and jquerytools slider requires the position be set to absolute, the containing div (#header) doesn't stretch to fit the content. I am trying to use jquery to get the height of the height of the img and apply that height to the header.... however I am having no luck. CSS: #header{ width:100%; position:relative; z-index: 20; /* box-shadow: 0 0 10px white; */ overflow: auto; } .scrollable { position:relative; overflow:hidden; width: 100%; height: 100%; /* box-shadow: 0 0 20px purple; */ /* height:198px; */ z-index: 20; overflow: auto; } .scrollable .items { /* this cannot be too large */ width:1000%; position:absolute; clear:both; /* box-shadow: 0 0 30px green; */ } .items div { float:left; width:10%; height:100%; } /* single scrollable item */ .scrollable img { /* float:left; */ width:100%; height: auto; /* height:198px; */ } /* active item */ .scrollable .active { border:2px solid #000; position:relative; cursor:default; } HTML <div id=header><!-- root element for scrollable --> <div class="scrollable" id="scrollable"> <!-- root element for the items --> <div class="items"> <div> <img src="img/img2.jpg" /> </div> <div> <img src="img/img1.jpg" /> </div> <div> <img src="img/img3.jpg" /> </div> <div> <img src="img/img4.jpg" /> </div> <div> <img src="img/img6.jpg" /> </div> </div><!-- items --> </div><!-- scrollable --> </div><!-- header -->

• How to be Agile when new work keeps affecting completed work?

  - by jdln

  The project I'm working on is to re-skin an existing website. The functionally will stay the same, its just the styles that are changing. The HTML is not changing, I'm only modifying the CSS files. The site is pretty complex. There are dozens of pages. Users can be logged in and have a number of different roles. Depending on their role the content of the page and what pages they are allowed to see varys. We're using GIT and Github. I'm trying to write CSS that works as components. So when the same form elements, headings, etc appear on multiple pages they are already styled and are consistent. Most of time this is working well. Sadly the format and class names in the HTML are at times messy and unpredictable. When I fix something on one page it can break another. The job is also harder as no one knows exactly all the variations that are possible due to the user roles. As such I'm continuously finding new variations as I go along. I'm making headway by putting a lot of comments in my CSS. If I need to remove a CSS rule Ill comment it out so I can still see it with the chrome dev tools, and ill put a comment in the CSS saying why I removed it and for what page this was done. This means that if on another page I'm about to add add the rule to fix a different problem, there is more of a chance I will see how this would break the first page. This allows me to either find a different solution that will work for both pages, or I can make the override page specific. This has been working quite well for me. If I had complete free reign and the only deadline was to finish the project by the end then this method would be fine. However my manager is trying to mitigate risk by breaking the work into areas to be completed per sprint. This is counter to how I have been approaching things as something like my typography styles will affect all other pages on the site. The other issue is that the different stakeholders want to sign off each section as I go along. However once I've finished a section it may change if I change CSS that affects it and also affects a new section I'm working on. I've asked that the stakeholders have a quick unofficial sign off in stages (eg per sprint), and have the final official sign off at the end of the project, but this is being met with resistance. I do understand why it would be higher risk to do this, but the only way to guarantee that a signed off section will not change is to make ALL future changes page specific. In addition to this I'm being told that all work that I push to the Git repo should be ready to go live, and as such should not contain any code comments. This is risky for me as I wont know until I've finished the site if I will ever benefit from these comments or not. Has anyone else been in a similar situation and managed to find a compromise that worked for my development approach and also the desires of management and stakeholders to have a more Agile approach? A more Agile workflow works great when you can break the work into components and know that once something is done it wont be affected by future work. However the nature of this project makes this hard to achieve.

• Running MS Access Programs

  - by fredhappier

  I have an old program developed in MS Access and would like to convert it to Kexi somehow. The program on Windows is launched with Access. Is there any way that Kexi can launch this program? I know my way around Ubuntu and the terminal, but not well versed on databases. Once you make something in Kexi how do you "run" it or "view" what you've made? So far I am able to import the MDB file into Kexi and see all of the database data, but that is as far I have gone. The program was made by a relative years ago for my dad. I myself am an Ubuntu only user for 6+ years now and have no intentions to touch Windows and am looking for a linux solution. My dad is also an Ubuntu user, hence why Im looking for a solution. If Kexi cannot launch and run an MDB file, what else can I try? Anything browser based? Any tips or direction would be extremely helpful. I spoke to my brother who originally made the program. I told him about Kexi and here is what he said. Does any of this make sense? Thanks. This is how I would try to get them to work: Stand alone setup - after import, look for an option where you designate which form object you want to open upon startup. It might be in the tools tab in the picture below. After you save that change, it re-start it and it should work. Front end/back end setup - Do what I suggested for the stand alone setup to the "front-end" MDB file. After you do that, put the other file (table MDB file) where you want it to reside on the network. Now, open back up the "front end" file and look for an option that will allow you to "connect" to those tables in the other file. It looks like it could be in the "External data" tab in the picture below. For this setup, you may need to do these two tasks in the reverse order I just mentioned. Thanks! Fred

• Development Approach: User Interface In or Domain Model Out?

  - by Berin Loritsch

  While I've never delivered anything using Smalltalk, my brief time playing with it has definitely left its mark. The only way to describe the experience is MVC the way it was meant to be. Essentially, all the heavy lifting for your application is done in the business objects (or domain model if you are so inclined). The standard controls are bound to the business objects in some way. For example, a text box is mapped to an object's field (the field itself is an object so it's easy to do). A button would mapped to a method. This is all done with a very simple and natural API. We don't have to think about binding objects, etc. It just works. Yet, in many newer languages and APIs you are forced to think from the outside in. First with C++ and MFC, and now with C# and WPF, Microsoft has gotten it's developer world hooked on GUI builders where you build your application by implementing event handlers. Java Swing development isn't so different, only you are writing the code to instantiate the controls on the form yourself. For some projects, there may never even be a domain model--just event handlers. I've been in and around this model for most of my carreer. Each way forces you to think differently. With the Smalltalk approach, your domain is smart while your GUI is dumb. With the default VisualStudio approach, your GUI is smart while your domain model (if it exists) is rather anemic. Many developers that I work with see value in the Smalltalk approach, and try to shoehorn that approach into the VisualStudio environment. WPF has some dynamic binding features that makes it possible; but there are limitations. Inevitably some code that belongs in the domain model ends up in the GUI classes. So, which way do you design/develop your code? Why? GUI first. User interaction is paramount. Domain first. I need to make sure the system is correct before we put a UI on it. There's pros and cons for either approach. Domain model fits in there with crystal cathedrals and pie in the sky. GUI fits in there with quick and dirty (sometimes really dirty). And for an added bonus: How do you make sure the code is maintainable?

• JQuery Validation [migrated]

  - by user41354

  Im trying to get my form to validate...so basically its working, but a little bit too well, I have two text boxes, one is a start date, the other an end date in the format of mm/dd/yyyy if the start date is greater than the end date...there is an error if the end date is less than the start date...there is an error if the start date is less than today's date...there is an error The only thing is when I correct the error, the error warning is still there...here is my code: dates.change(function () { var testDate = $(this).val(); var otherDate = dates.not(this).val(); var now = new Date(); now.setHours(0, 0, 0, 0); // Pass Dates if (testDate != '' && new Date(testDate) < now) { addError($(this)); $('.flightDateError').text('* Dates cannot be earlier than today.'); isValid = false; return; } // Required Text if ($(this).hasClass("FromCal") && testDate == '') { addError($(this)); $('.flightDateError').text('* Required'); isValid = false; return; } // Validate Date if (!isValidDate(testDate)) { // $(this).addClass('validation_error_input'); addError($(this)); $('.flightDateError').text('* Invalid Date'); isValid = false; return; } else { // $(this).removeClass('validation_error_input'); removeError($(this)); if (!dates.not(this).hasClass('validation_error_input')) $('.flightDateError').text(' '); } // Validate Date Ranges if ($(this).val() != '' && dates.not(this).val != '') { if ($(this).hasClass("FromCal")) { if (new Date(testDate) > new Date(otherDate)) { addError($(this)); $('.flightDateError').text('* Start date must be earlier than end date.'); isValid = false; return; } } else{ if (new Date(testDate) < new Date(otherDate)) { addError($(this)); $('.flightDateError').text('* End date must be later than start date.'); return; } } } }); The main Issue is this part, I believe // Validate Date Ranges if ($(this).val() != '' && dates.not(this).val != '') { if ($(this).hasClass("FromCal")) { if (new Date(testDate) > new Date(otherDate)) { addError($(this)); $('.flightDateError').text('* Start date must be earlier than end date.'); isValid = false; return; } } else{ if (new Date(testDate) < new Date(otherDate)) { addError($(this)); $('.flightDateError').text('* End date must be later than start date.'); return; } } } testDate is the start date otherDate is the end date Thanks in advanced, J

• Reinstall Acer OEM Windows 8, Windows 8 Recovery for Acer Aspire V5 122p

  - by stwindr

  My Acer Aspire V5-122P-61456G50NSS, model - MS2377, has crashed all together. It came preloaded with Windows 8 and I upgraded to windows 8.1 3-4 days before crash. Unfortunately I did not make any recovery media before the crash. While accessing the eRecovery on Acer store with my PC's serial no. it says nor RCD available for this. I tried recovery by loading recovery manager (Left Alt + F10) Various other advanced startup options (like holding shift key while turning on or pressing F8 key) returns nothing but no luck. However I am able to enter BIOS. After doing research on above condition on various PC forums, now my questions: I read that a 'Windows Recovery Drive' can be made on any PC running Windows 8 and could be used to repair another PC. Does anybody in SuperUser community have that (or a link to download the same from somewhere? as I'm unable to find anybody running windows 8 among my friends). I downloaded a window 8 Pro ISO and made a bootable USB. I was able to go to 'Repair Your Computer' option and after going to 'Reset your PC' option found that my recovery partition has gone/missing. I tried all options available but no luck. Then I tried to install with that Windows 8 Pro ISO but got message: "The product key entered does not match any of the Windows images available for installation. Enter a different product key". before this message I did not got any form to fill product key! Does this mean that the installer was picking up the key from BIOS (OEM Key)? and may be the installation did not succeeded because OEM Windows version was Window 8 and I was trying to install Windows 8 Pro. If that is the case then, could somebody please send me link to download an Windows 8 ISO? I am helpless and couldn't find anywhere on internet (without having to pay for a new key, but I should not pay as the installer will use OEM key).

• HP DL160G6 bios update fails

  - by Bojo

  I tried to update the BIOS from my HP DL160G6's. Unfortunately the Windows update degraded my BIOS version from 243 to 237. But when I try to upgrade both servers to version the update fails. First I got a warning like: CMOS Layout difference between System ROM and ROM file has detected. AFU recommand (sic) adding /C commands of your original input commands. Press "A" to accept AFU's recommendation. Press "F" to keep original input commands. And the update did not do anything. But now I get a message like: Reading flash ........ done Bootblock checksum ... ok Module checksums ..... bad Error: BIOS checksum error And the update stops. I tried some commands form this page: http://www.ami.com/support/downloads/txt/AFU_README.TXT But I don't try to much, the servers are still booting. Does anyone know how to update my servers to BIOS version 245? I used this version http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdDetails/?sp4ts.oid=3884344&spf_p.tpst=swdMain&spf_p.prp_swdMain=wsrp-navigationalState%3Didx%253D%257CswItem%253DMTX_7bd12651ab954fdcb0d7ee164a%257CswEnvOID%253D54%257CitemLocale%253D%257CswLang%253D%257Cmode%253D%257Caction%253DdriverDocument&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken and created a bootable USB stick sith HPQUSB.exe

• VLC (Server) re-stream Security Camera Feed

  - by Aaron

  I purchased a Swann Home Security DVR system and was hoping for some help on how to duplicate the streaming video on my server. In order to get their web view (streaming video in the browser) to work, I had to install the following plugins: HiDvrPlugin.dmg for mac. Hidvrocx.cab for Windows. I was originally thinking it was a sign of some form of DRM? Maybe. Maybe not. HTML wise, the following code is in the source of the safari version of the web view: <embed pluginspage="SurveilClient.dmg" width="10px" height="10px" type="application/x-scplugin" id="MacDiv" style="height: 592px; width: 720px; left: 278px; top: 61px; "> It seems to be the main display area. Using wireshark, I am able to see that the video stream is on port 9000. However, I have no idea what type of stream it is. I've tried opening it in VLC with no such luck. http://dvr_ip:9000 tcp://dvr_ip:9000 My hope was to do the following to redistribute the feed vlc dvr_ip:9000 --sout h264-version-on-localhost:3000 TLDR; Trying to re-distribute a stream from a security camera (can't tell the format) using vlc (re-distribute via h.264 / HTML5). Not sure how to accomplish this. Is it possible that the software has some type of DRM that only the plugins can decode?

• Indesign Import XML into Automatic Page generation, data merge

  - by taudep

  I've created some InDesign Pages that I want to use as templates. I've created an XML file with all the appropriate data. I want to merge the XML data with the InDesign page and have a few hundred pages automatically generated. I've been reading online and working with InDesign's "Import XML" features without any luck. The documentation has been pretty poor for me. And Google searches haven't returned much fruitful. Edit: I'm updating this to now include my present steps 1) I create a Master Page of my template 2) I add a bunch of text frames where I want the imported data from the XML file to be places 3) I open the "Tags" window and Import and XML file 4) I mark my text frames in the Master Document with the appropriate tags 5) I then add a lot of pages (like 200) to the document 6) Then I use "Import XML" to try and get the data brought in and filled across all 200 pages. This is where I fail. So there's something I'm missing. It might be that InDesign doesn't work as I'm expecting... Anyone have any good tips for mail-merge like functionality with an XML document and auto-generation of InDesign pages? BTW, here's an example of Adobe's great documentation for merging repeated XML elements. There's gotta be more...InDesign CS4 Docs: XML-Importing XML-Working with Repeating Data EDIT: Here's some of the sample XML, notice the ITEM will repeat.

• windows firewall broken on server 2008

  - by Chloraphil

  This evening I tried to rdp into my server 2008 box and was unable to. After poking around some I discovered that something is awry with my Windows Firewall. I did install 5 windows updates remotely earlier today but rolled those back in an attempt to see if that fixed the problem but had no luck. Symptoms: cannot rdp to machine (including from itself) cannot ping machine cannot connect to file share on machine error message when attempting to open "windows firewall with advanced security" snap-in (there was an error opening the windows firewall with advanced security snap-in ... The Windows Firewall with Advanced Security snap-in failed to load. Restart the windows firewall service on the computer that you are managing. Error code: 0x6D9. When I opened the "user-friendly" Windows Firewall it failed to load most of the gui elements, meaning, the title bar with close, minimize, and maximize buttons is present, the rest of the window has a white background with a yellow rectangle with rounded corners and a yellow triangle w/ an exclamation point is in the upper right. hope that made sense "Windows Firewall" does not appear in the list of services I ran a virus scan that found nothing. How do I fix the firewall and hopefully restore the ability to rdp? EDIT: Added at fission's request: c:\sc query mpsdrv SERVICE_NAME: mpsdrv TYPE : 1 KERNEL_DRIVER STATE : 4 RUNNING (STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN) WIN32_EXIT_CODE : 0 (0x0) SERVICE_EXIT_CODE : 0 (0x0) CHECKPOINT : 0x0 WAIT_HINT : 0x0 c:\sc query mpssvc SERVICE_NAME: mpssvc TYPE : 20 WIN32_SHARE_PROCESS STATE : 1 STOPPED WIN32_EXIT_CODE : 1068 (0x42c) SERVICE_EXIT_CODE : 0 (0x0) CHECKPOINT : 0x0 WAIT_HINT : 0x0 Those two registry keys do exist: HKLM\SYSTEM\CurrentControlSet\Services\mpsdrv & HKLM\SYSTEM\CurrentControlSet\Services\MpsSvc ! The problem seems to be with the Base Filtering Engine, when I try to start it I get the following error: Windows could not start the Base Filtering Engine service on MYCOMPUTER. Error 15100: The resource loader failed to find MUI file. EDIT2: I ran sfc /scannow and i found about 100 occurrences of "[SR] Cannot repair member file"... including several related to the firewall (ex: [l:32{16}]"Firewall.cpl.mui" of Networking-MPSSVC.Resources...). One of them mentioned wordpad.exe, which I tried to open, and it failed. I found here mentions of mounting the install.wim on the install media to copy the affected files over. I am downloading the appropriate AIK and will continue tomorrow evening.
