  • Web Application: Combining View Layer Between PHP and Javascript-AJAX

    - by wlz
    I'm developing web application using PHP with CodeIgniter MVC framework with a huge real time client-side functionality needs. This is my first time to build large scale of client-side app. So I combine the PHP with a large scale of Javascript modules in one project. As you already know, MVC framework seperate application modules into Model-View-Controller. My concern is about View layer. I could be display the data on the DOM by PHP built-in script tag by load some data on the Controller. Otherwise I could use AJAX to pulled the data -- treat the Controller like a service only -- and display the them by Javascript. Here is some visualization I could put the data directly from Controller: <label>Username</label> <input type="text" id="username" value="<?=$userData['username'];?>"><br /> <label>Date of birth</label> <input type="text" id="dob" value="<?=$userData['dob'];?>"><br /> <label>Address</label> <input type="text" id="address" value="<?=$userData['address'];?>"> Or pull them using AJAX: $.ajax({ type: "POST", url: config.indexURL + "user", dataType: "json", success: function(data) { $('#username').val(data.username); $('#dateOfBirth').val(data.dob); $('#address').val(data.address); } }); So, which approach is better regarding my application has a complex client-side functionality? In the other hand, PHP-CI has a default mechanism to put the data directly from Controller, so why using AJAX?

  • Scaling Scrum within a group of 100s of programmers

    - by blunders
    Most Scrum teams lean toward 7-15 people **, though it's not clear how to scale Scrum among 100s of people, or how the effectiveness of a given team might be compared to another team within the group; meaning beyond just breaking the group into Scrum teams of 7-15 people, it's unclear how efforts between the teams are managed, compared, etc. Any suggestions related to either of these topics, or additional related topics that might be of more importance to account for in planning a large scale SCRUM grouping? ** In reviewing research related to the suggested size of software development teams, which appears to be the basis for the suggested Scrum team size, I found what appears to be an error in the research which oddly appears to show that bigger teams (15+ ppl), not smaller teams (7 ppl) are better. UPDATE, "Re: Scrum doesn't scale": Made huge amounts of progress on personally researching the topic, but thought I'd respond to the general belief of some that Scrum doesn't scale by citing a quote from Succeeding with Agile by Mike Cohn : Scrum Does Scale: You have to admire the intellectual honesty of the earliest agile authors. They were all very careful to say that agile methodolgies like Scrum were for small projects. This conservatism wasn’t because agile or Scrum turned out to be unsuited for large projects but because they hadn’t used these processes on large projects and so were reluctant to advise their readers to do so. But, in the years since the Agile Manifesto and the books that came shortly before and after it, we have learned that the principles and practices of agile development can be scaled up and applied on large projects, albeit it with a considerable amount of overhead. Fortunately, if large organizations use the techniques described regarding the role of the product owner, working with a shared product backlog, being mindful of dependencies, coordinating work among teams, and cultivating communities of practice, they can successfully scale a Scrum project.

  • Collaboration using github and testing the code

    - by wyred
    The procedure in my team is that we all commit our code to the same development branch. We have a test server that runs updated code from this branch so that we can test our code on the servers. The problem is that if we want to merge the development branch to the master branch in order to publish new features to our production servers, some features that may not have been ready will be applied to the production servers. So we're considering having each developer work on a feature/topic branch where each of them work on their own features and when it's ready, merge it into the development branch for testing, and then into the master branch. However, because our test server only pulls changes from the development branch, the developers are unable to test their features. While this is not a huge issue as they can test it on their local machine, the only problem I foresee is if we want to test callbacks from third-party services like sendgrid (where you specify a url for sendgrid to update you on the status of emails sent out). How to handle this problem? Note: We're not advanced git users. We use the Github app for MacOSX and Windows to commit our work.

  • What is the value in hiding the details through abstractions? Isn't there value in transparency?

    - by user606723
    Background I am not a big fan of abstraction. I will admit that one can benefit from adaptability, portability and re-usability of interfaces etc. There is real benefit there, and I don't wish to question that, so let's ignore it. There is the other major "benefit" of abstraction, which is to hide implementation logic and details from users of this abstraction. The argument is that you don't need to know the details, and that one should concentrate on their own logic at this point. Makes sense in theory. However, whenever I've been maintaining large enterprise applications, I always need to know more details. It becomes a huge hassle digging deeper and deeper into the abstraction at every turn just to find out exactly what something does; i.e. having to do "open declaration" about 12 times before finding the stored procedure used. This 'hide the details' mentality seems to just get in the way. I'm always wishing for more transparent interfaces and less abstraction. I can read high level source code and know what it does, but I'll never know how it does it, when how it does it, is what I really need to know. What's going on here? Has every system I've ever worked on just been badly designed (from this perspective at least)? My philosophy When I develop software, I feel like I try to follow a philosophy I feel is closely related to the ArchLinux philosophy: Arch Linux retains the inherent complexities of a GNU/Linux system, while keeping them well organized and transparent. Arch Linux developers and users believe that trying to hide the complexities of a system actually results in an even more complex system, and is therefore to be avoided. And therefore, I never try to hide complexity of my software behind abstraction layers. I try to abuse abstraction, not become a slave to it. Question at heart Is there real value in hiding the details? Aren't we sacrificing transparency? Isn't this transparency valuable?

  • One page using querystring or many folders and pages?

    - by ClarkeyBoy
    I have an application where I have the 'core' code in one folder for which there is a virtual directory in the root, such that I can include any core files using /myApp/core/bla.asp. I then have two folders outside of this with a default.asp which currently use the querystring to define what page should be displayed. One page is for general users, the other will only be accessible to users who have permission to manage users / usergroups / permissions. The core code checks the querystring and then checks the permissions for that user. An example of this as it is now is default.asp?action=view&viewtype=list&objectid=server. I am not worried about SEO as this is an internal app and uses Windows Auth. My question is, is it better the way it is now or would it be better to have something like the following: /server/view/list/ /server/view/?id=123 /server/create/ /server/edit/?id=123 /server/remove/?id=123 In the above folders I would have a home page which defines all the variables which are currently determined by the querystring - in /server/create/ for example, I would define the action as 'create', object name as 'server' and so on. In terms of future development, I really have no idea which method would be best. I think the 2nd method would be best in terms of following what page does what but this is such a huge change to make at this stage that I would really like some opinions, preferably based on experience. PS Sorry if the tags are wrong - I am new to this forum and thought this was a bit too much of a discussion for StackOverflow as that is very much right / wrong answer based. I got the idea SE is more discussion based.

  • How to Reach German Developers: dotnet Cologne 2011

    - by WeigeltRo
    If you want to promote tools, technologies, libraries, trainings or anything else of interest to software developers, you want to reach the right audience. Not the 9-to-5 people, but those who have the knowledge and passion that make them important multipliers. A great way to reach these people are community conferences. They are not the kind of conference that the 9-to-5 folks are “sent to” by their company, but that the right people hear of via Twitter, Facebook, blogs or plain old word-of-mouth and choose to go to, often covering the costs for the day themselves (travel, entrance fee, hotel, taking the day off). If you want to reach German developers there is one conference that has emerged as the large .NET community conference in Germany, quickly growing beyond being just a local event: The dotnet Cologne, that will be held for the third time on May 6, 2011 and that I’m co-organizing (this interview gives you a good idea of the history). This year’s dotnet Cologne 2010 with its 300 attendees was a huge success. As in the year before, the conference was sold out weeks in advance, and feedback by attendees and sponsors was positive throughout. And the list of speakers and attendees sounded like a “who is who” of the German .NET community. Whether you‘d like to present a product, a service or your company: you will meet the right target audience at dotnet Cologne. We’re offering a broad variety of sponsorship opportunities, ranging from being a donor for the large raffle at the end of the day (software licenses, books, training vouchers, etc.) up to having a booth and/or giving a sponsored talk about your product (not necessarily in German, English is not a problem). Among the various sponsorship levels (bronze/silver/gold/platinum) there’s most likely a package that will suit your needs – and if not, we’re open for suggestions. We’re happy to announce that already at this point in time (with over five months to go) we have a steadily growing list of partners: Microsoft, Intel, IDesign, SubMain, Comma Soft AG, GFU Köln, and EC Software. If you want to become a sponsor for the dotnet Cologne 2011, drop me a line at Roland.Weigelt at dotnet-koelnbonn.de and I’ll send you our sponsor info.

  • MIX 2010 Covert Operations Day 4

    - by GeekAgilistMercenary
    The Microsoft Azure Cloud is looking pretty solid compared to just a few months ago.  The storage mechanisms in the cloud now are blobs, drives, tables, and queues.  Also, not to forget, is SQL Azure.  I won’t dive too much into that, as most will know what SQL Server is, and SQL Azure is pretty much just a hosted SQL Server instance. The blobs are generally geared toward holding binary type data, images and those types of things.  The tables are huge key value type stores.  The drives are VHD, which are virtual hard drives.  The queues are just queues used for workflow and also to store messages back and forth in a queue. These methods are accessible via REST, which makes application development against the storage services extremely easy.  This is a big plus point as REST services are a preferred way to connect and interact with data storage.  It also sets up Silverlight as a prime framework to utilize services. Day 4 I pretty much dedicated to reviewing these cloud services and finishing up work related development.  With that, I'm wrapping up my MIX 2010 blog coverage.  Now back to your regularly scheduled programming. Original entry.

  • White box testing with Google Test

    - by Daemin
    I've been trying out using GoogleTest for my C++ hobby project, and I need to test the internals of a component (hence white box testing). At my previous work we just made the test classes friends of the class being tested. But with Google Test that doesn't work as each test is given its own unique class, derived from the fixture class if specified, and friend-ness doesn't transfer to derived classes. Initially I created a test proxy class that is friends with the tested class. It contains a pointer to an instance of the tested class and provides methods for the required, but hidden, members. This worked for a simple class, but now I'm up to testing a tree class with an internal private node class, of which I need to access and mess with. I'm just wondering if anyone using the GoogleTest library has done any white box testing and if they have any hints or helpful constructs that would make this easier. Ok, I've found the FRIEND_TEST macro defined in the documentation, as well as some hints on how to test private code in the advanced guide. But apart from having a huge amount of friend declerations (i.e. one FRIEND_TEST for each test), is there an easier idion to use, or should I abandon using GoogleTest and move to a different test framework?

  • Red Dot Scope Makes Sighting In Long Lenses a Snap

    - by Jason Fitzpatrick
    If you’ve ever used a high power lens, you know how tricky it can be to sight a distant subject as the field of view through the lens is so tiny. This hack takes care of that problem by using a zero-magnification red dot rifle scope. Chris Malcolm enjoys photographing birds and other wildlife with high power lenses. The problem, when shooting with huge 500mm lens and other high power lenses, is that they’re practically telescopes and acquiring a fast moving target like a bird using a through-the-lens technique is very tricky. Malcolm’s solution hinges on mounting a zero-magnification red dot rifle scope in parallel with the lens. His mock up is a bit unpolished (although we can understand not wanting to run out and buy a brand new black scope just for the experiment) but works great to get him on target. Hit up the link below to read more about his build, how be created the rail mount for the scope, and why he opted to mount it to the barrel of the lens and not the hot shoe mount on the camera. 500mm Reflex Lens with Red Dot Sight [via DIY Photography] Make Your Own Windows 8 Start Button with Zero Memory Usage Reader Request: How To Repair Blurry Photos HTG Explains: What Can You Find in an Email Header?

  • AutoHotkey cannot interact with Windows 8 Windows&hellip;or can it!

    - by deadlydog
    If you’ve installed Windows 8 and are trying to use AutoHotkey (AHK) to interact with some of the Winodws 8 Windows (such as the Control Panel for example), or with apps that need to be Ran As Administrator, then you’ve likely become very frustrated as I did to discover that AHK can not send any commands (keyboard or mouse input) to these windows.  This was a huge concern as I often need to run Visual Studio as an administrator and wanted my hotkeys and hotstrings to work in Visual Studio.  After a day of fighting I finally realized the answer (and it’s pretty obvious once you think about it).  If you want AHK to be able to interact with Windows 8 Windows or apps running as administrator, then you also need to have your AHK script Run As Administrator. If you are like me then you probably have your AHK scripts set to run automatically at login, which means you don’t have the opportunity to right-click on the script and manually tell it to Run As Administrator.  Luckily the work around is simple.  First, if you want to have your AHK script (or any program for that matter) run when you log in, create a shortcut to the application and place the shortcut in: C:\Users\[User Name]\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup Note that you will need to replace “[User Name]” with your username, and that “AppData” is a hidden folder so you’ll need to turn on viewing hidden folders to see it.  So by placing that shortcut there Windows will automatically run your script when you log on.  Now, to get it to run as an administrator by default, right-click on the shortcut and go to Properties.  Under the Shortcut tab, click on the “Advanced…” button and check off “Run as administrator”.  That’s it.  Now when you log onto Windows your script will automatically start up, running as an administrator; allowing it to interact with any application and window like you had expected it to in the first place.   Happy coding!

  • TechEd Europe early bird saving &ndash; register by 5th July

    - by Eric Nelson
    Another event advert alert :-) But this one comes with a cautious warning. I spoke at TechEd Europe last year. I found TechEd to be a huge, extremely well run conference filled with great speakers and passionate attendees in a top notch venue and fascinating city. As an “IT Pro” I think it is the premiere conference for Microsoft technologies in Europe. However, IMHO and those of others I trust, I didn’t think it hit the mark for developers in 2009. There was a fairly obvious reason – the PDC was scheduled to take place only a couple of weeks later which meant the “powder was being kept dry” and (IMHO) some of the best speakers on developer technologies were elsewhere. But I’m reasonably certain that this won’t be repeated this year (Err… Have I missed an announcement about “no pdc in 2010”?) Enjoy: Register for Tech·Ed Europe by 5 July and Save €500 Tech·Ed Europe returns to Berlin this November 8 – 12, for a full week of deep technical education, hands-on-learning and opportunities to connect with Microsoft and Community experts one-on-one.  Register by 5 July and receive your conference pass for only €1,395 – a €500 savings. Arrive Early and Get a Jumpstart on Technical Sessions Choose from 8 pre-conference seminars led by Microsoft and industry experts, and selected to give you a jumpstart on technical learning.  Additional fees apply.  Conference attendees receive a €100 discount.   Join the Tech·Ed Europe Email List for Event Updates Get the latest event news before the event, and find out more about what’s happening onsite.  Join the Tech·Ed Europe email list today!

  • Is SQL Azure a newbies springboard?

    - by jamiet
    Earlier today I was considering the various SQL Server platforms that are available today and I wondered aloud, wonder how long until the majority of #sqlserver newcomers use @sqlazure instead of installing locally Let me explain. My first experience of development was way back in the early 90s when I would crank open VBA in Access or Excel and start hammering out some code, usually by recording macros and looking at the code that they produced (sound familiar?). The reason was simple, Office was becoming ubiquitous so the barrier to entry was incredibly low and, save for a short hiatus at university, I’ve been developing on the Microsoft platform ever since. These days spend most of my time using SQL Server. I take a look at SQL Azure today I see a lot of similarities with those early experiences, the barrier to entry is low and getting lower. I don’t have to download some software or actually install anything other than a web browser in order to get myself a fully functioning SQL Server  database against which I can ostensibly start hammering out some code and I believe that to be incredibly empowering. Having said that there are still a few pretty high barriers, namely: I need to get out my credit card Its pretty useless without some development tools such as SQL Server Management Studio, which I do have to install. The second of those barriers will disappear pretty soon when Project Houston delivers a web-based admin and presentation tool for SQL Azure so that just leaves the matter of my having to use a credit card. If Microsoft have any sense at all then they will realise the huge potential of opening up a free, throttled version of SQL Azure for newbies to party on; they get to developers early (just like they did with me all those years ago) and it gives potential customers an opportunity to try-before-they-buy. Perhaps in 20 years time people will be talking about SQL Azure as being their first foray into the world of coding! @Jamiet Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Declarative View Objects (VOs) for better ADF performance

    - by Shay Shmeltzer
    Just got back from ODTUG's kscope13 conference which had a lot of good deep ADF content. In one of my session I ran out of time to do one of my demos, so I wanted to share it here instead. This is a demo of how Declarative View Objects can increase your application's performance. For those who are not familiar with declarative VOs, those are VOs that don't actually specify a hard coded query. Instead ADF creates their query at runtime, and it does it based on the data that is requested in your UI layer. This can be a huge saver of both DB resources and network resources. More in the documentation. Here is a quick example that shows you how using such a VO can automatically switch to a simpler SQL instead of a complex join when needed. (note while I demo with 11.1.2.* the feature is there in 11.1.1.* versions also). The demo also shows you how you can monitor the SQL that ADF BC issues to the database using the WebLogic logging feature in JDeveloper. As a side note, I would have loved to see more ADF developers attending Kscope. This demo was part of the "ADF intro" track at Kscope, In the advanced ADF track you would have been treated to a full tuning session about ADF with lots of other tips. Consider attending Kscope next year - it is going to be in Seattle this time.

  • Why ADF Developers Should Attend ODTUG This Year

    - by shay.shmeltzer
    If you are using Oracle ADF or planning to pick it up in the next year, I would encourage you to try and attend this year's ODTUG K-Scope conference. If you are not familiar with it, ODTUG - the Oracle Development Tools User Groups - holds a yearly conference that is very technical in nature. It is not a huge conference in terms of the number of attendees, but this just means that you have more opportunities to interact with Oracle ACEs, Oracle Product Managers, and other developers. The conference is known to be a no-fluff, no-marketing, technical conference. This year however there is one key new thing that should be of interest to readers of this blog. A new track called the "Fusion Middleware" track has been formed and it has lots of sessions for any level of ADF developer. The track is run by several Oracle ACEs who are also involved in the ADF Enterprise Methodology Group. They have sessions for every level of ADF awareness - from the beginner to the expert, and you can also learn about related technologies such as WebCenter and SOA Suite. Most of the sessions are run by users who share their real world experience with the technology. And me and other PMs will also be running a few sessions and hands-on labs there. Check out the list of sessions in the Fusion Middleware track. And don't miss the Sunday symposium too.

  • Is it bad practice for services to share a database in SOA?

    - by Paul T Davies
    I have recently been reading Hohpe and Woolf's Enterprise Integration Patterns, some of Thomas Erl's books on SOA and watching various videos and podcasts by Udi Dahan et al. on CQRS and Event Driven systems. Systems in my place of work suffer from high coupling. Although each system theoretically has its own database, there is a lot of joining between them. In practice this means there is one huge database that all systems use. For example, there is one table of customer data. Much of what I've read seems to suggest denormalising data so that each system uses only its database, and any updates to one system are propagated to all the others using messaging. I thought this was one of the ways of enforcing the boundaries in SOA - each service should have its own database, but then I read this: http://stackoverflow.com/questions/4019902/soa-joining-data-across-multiple-services and it suggests this is the wrong thing to do. Segregating the databases does seem like a good way of decoupling systems, but now I'm a bit confused. Is this a good route to take? Is it ever recommended that you should segregate a database on, say an SOA service, an DDD Bounded context, an application, etc?

  • EF4 CPT5 Code First Remove Cascading Deletes

    - by Dane Morgridge
    I have been using EF4 CTP5 with code first and I really like the new code.  One issue I was having however, was cascading deletes is on by default.  This may come as a surprise as using Entity Framework with anything but code first, this is not the case.  I ran into an exception with some one-to-many relationships I had: Introducing FOREIGN KEY constraint 'ProjectAuthorization_UserProfile' on table 'ProjectAuthorizations' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints. Could not create constraint. See previous errors. To get around this, you can use the fluent API and put some code in the OnModelCreating: 1: protected override void OnModelCreating(System.Data.Entity.ModelConfiguration.ModelBuilder modelBuilder) 2: { 3: modelBuilder.Entity<UserProfile>() 4: .HasMany(u => u.ProjectAuthorizations) 5: .WithRequired(a => a.UserProfile) 6: .WillCascadeOnDelete(false); 7: } This will work to remove the cascading delete, but I have to use the fluent API and it has to be done for every one-to-many relationship that causes the problem. I am personally not a fan of cascading deletes in general (for several reasons) and I’m not a huge fan of fluent APIs.  However, there is a way to do this without using the fluent API.  You can in the OnModelCreating, remove the convention that creates the cascading deletes altogether. 1: protected override void OnModelCreating(System.Data.Entity.ModelConfiguration.ModelBuilder modelBuilder) 2: { 3: modelBuilder.Conventions.Remove<OneToManyCascadeDeleteConvention>(); 4: } Thanks to Jeff Derstadt from Microsoft for the info on removing the convention all together.  There is a way to build a custom attribute to remove it on a case by case basis and I’ll have a post on how to do this in the near future.

  • Open source clone for Starcraft

    - by sinekonata
    Two questions about a SC:Broodwar clone. Is there one yet? How likely is legal pursuit? Since almost all games I usually play now have an FOS alternative from alpha to way polished, I was wondering why can't I find one for SC, one of the biggest titans of the gaming community? So my first question is, is there a game that was made with the intention to emulate SC? Is it that I didn't look well enough? Could it really be that no one tackled what seems like a small effort compared to the creation of a game engine like Spring or games like Rigs of Rod or Minetest? And since SC is not being maintained at all shouldn't the incentive to see a bug free modable balanced version huge? What am I not getting here? In the event that there is none, is it a legal problem? Could it be that people expect Blizzard to release sources themselves? Or that developers don't see the point in having SC mechanics without the patented lore and aesthetics? And the trickier question, if I were to make SC an open source game, a total clone of it for the purposes of maintenance, modability, etc. Would Blizzard really sue a team of developer fans that just do them a favour knowing they don't lose any money from Korea broadcasts? Or would they do it not to set precedents. So thanks for reading all that, hope I'm not the only one to think it's weird that no one talks about it. See you.

  • Alternative to Game State System?

    - by Ricket
    As far as I can tell, most games have some sort of "game state system" which switches between the different game states; these might be things like "Intro", "MainMenu", "CharacterSelect", "Loading", and "Game". On the one hand, it totally makes sense to separate these into a state system. After all, they are disparate and would otherwise need to be in a large switch statement, which is obviously messy; and they certainly are well represented by a state system. But at the same time, I look at the "Game" state and wonder if there's something wrong about this state system approach. Because it's like the elephant in the room; it's HUGE and obvious but nobody questions the game state system approach. It seems silly to me that "Game" is put on the same level as "Main Menu". Yet there isn't a way to break up the "Game" state. Is a game state system the best way to go? Is there some different, better technique to managing, well, the "game state"? Is it okay to have an intro state which draws a movie and listens for enter, and then a loading state which loops on the resource manager, and then the game state which does practically everything? Doesn't this seem sort of unbalanced to you, too? Am I missing something?
