• How to set up a personal Apple developer account now with an eye on transferring app ownership to a company later?

  - by Rinzwind

  I have two Mac applications that I wrote for my own personal use, but I'm considering polishing them up and giving selling them on the Mac App Store a try. It seemed very premature to consider what would happen if either app would become successful enough to make it possible to set up a business around it, or to sell it to another developer. That is, until I read that Apple doesn't make it easy to transfer app ownership. I'm not sure how to best register with the Apple Developer program now to avoid any possible hassle in this respect later. From what I understand, one can really only transfer ownership of a developer account. I'm not sure about the relationship between an Apple ID and an Apple developer account. Does this mean I should at least not use the Apple ID I'm already using for iTunes, but create a second one to use for registering as an Apple Developer? Is there any disadvantage to using separate Apple IDs like this on the same Mac (one ID for Xcode development, the other ID for iTunes/iCloud/App Store/...)? Should one go as far as having a separate Apple ID & Apple developer account per app one develops? Or is there some other solution to take into account the possibility of transferring app ownership?

• Best setup/workflow for distributed team to integrated DSVC with fragmented huge .NET site?

  - by lazfish

  So we have a team with 2 developers one manager. The dev server sits in a home office and the live server sits in a rack somewhere handled by the larger part of my company. We have freedom to do as we please but I want to incorporate Kiln DSVC and FogBugz for us with some standard procedures to make sense of our decisions/designs/goals. Our main product is web-based training through our .NET site with many videos etc, and we also do mobile apps for multiple platforms. Our code-base is a 15 yr old fragmented mess. The approach has been rogue .asp/.aspx pages with some class management implemented in the last 6 years. We still mix our html/vb/js all on the same file when we add a feature/page to our site. We do not separate the business logic from the rest of the code. Wiring anything up in VS for Intelli-sense or testing or any other benefit is more frustrating than it is worth, because of having to manually rejigger everything back to one file. How do other teams approach this? I noticed when I did wire everything up for VS it wants to make a class for all functions. Do people normally compile DLLs for page-specific functions that won't be reusable? What approaches make sense for getting our practices under control while still being able to fix old anti-patterns and outdated code and still moving towards a logical structure for future devs to build on?

• Strategy to store/average logs of pings

  - by José Tomás Tocino

  I'm developing a site to monitor web services. The most basic type of check is sending a ping, storing the response time in a CheckLog object. By default, PingCheck objects are triggered every minute, so in one hour you get 60 CheckLogs and in one day you get 1440 CheckLogs. That's a lot of them, I don't need to store such level of detail, so I've set a up collapsing mechanism that periodically takes the uncollapsed CheckLogs older than 24h and collapses (averages) them in intervals of 30 minutes. So, if you have 360 CheckLogs that have been saved from 0:00 to 6:00, after collapsing you retain just 12 of them. The problem.. well, is this: After averaging the response times, the graph changes drastically. What can I do to improve this? Guess one option could be narrowing the interval duration to 15 min. I've seen the graphs at the GitHub status page and they do not seem to suffer from this problem. I'd appreciate any kind of information you could give me about this area.

• 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?

• How to build an API on top of an existing Rails app with NodeJs and what architecture to use?

  - by javiayala

  The explanation I was recently hired by a company that has an old RoR 2.3 application with more than 100k users, a strong SEO strategy with more than 170k indexed urls, native android and ios applications and other custom-made mobile and web applications that rely on a not so good API from the same RoR app. They recently merged with a company from another country as an strategy to grow the business and the profit. They have almost the same stats, a similar strategy and mobile apps. We have just decided that we need to merge the data from both companies and to start a new app from scratch since the RoR app is to old and heavily patched and the app from the other company was built with a custom PHP framework without any documentation. The only good news is that both databases are in MySQL and have a similar structure. The challenge I need to build a new version that: can handle a lot of traffic, preserves the SEO strategies of both companies, serve 2 different domains, and have a strong API that can support legacy mobile apps from both companies and be ready for a new set of native apps. I want to use RoR 3.2 for the main web apps and NodeJs with a Restful API. I know that I need to be very careful with the mobile apps and handle multiple versions of the API. I also think that I need to create a service that can handle a lot IO request since the apps is heavily used to create orders for restaurants at a certain time of the day. The questions With all this in mind: What type of architecture do you recommend me to follow? What gems or node packages do you think will work the best? How do I build a new rails app and keep using the same database structure? Should I use NodeJS to build an API or just build a new service with Ruby? I know that I'm asking to much from you guys, but please help me by answering any topic that you can or by pointing me on the right direction. All your comments and feedback will be extremely appreciated! Thanks!

• Domain model integration using JSON capable DTOs

  - by g-makulik

  I'm a bit confused about architectural choices for the java/web-applications world. The background is I have a system with certain hardware components (that introduce system immanent active behavior) and a configuration database for system meta and HW-components configuration data (these are even usually self contained, since the HW-components persist configuration data anyway). For realization of the configuration/status data exchange protocol with the HW-components we have chosen the Google Protobuf format, which works well for the directly wired communication with these components. Now we want to develop an abstract model (domain model) for those HW-components and I have the feeling that a plain Java class model would fit best for this (c++ implementation seems to have too much implementation/integration overhead with viable language-bridge interfaces). Google Protobuf message definitions could still serve well to describe DTO objects used to interact with a domain model API. But integrating Google Protobuf messages client side for e.g. data binding in the current view doesn't seem to be a good choice. I'm thinking about some extra serialization features, e.g. for JSON based data exchange with the views/controllers. Most lightweight solutions seem to involve a python based presentation layer using JSON based data transfer (I'm at least not sure to be fully informed about this). Is there some lightweight (applicable for a limited ARM Linux platform) framework available, supporting such architecture to realize a web-application?

• What makes one language any better than another when both are designed for the same goals? [closed]

  - by Justin808

  I'm in the process of creating a grammar for a scripting language but as I'm working on it I started to wonder what makes a language good in the first place. I know the goals for my script but there are always 1000 different ways to go about doing things. Goals: Easy to use and understand (not my grandma could do it easy, but the secretary at the front desk could do it or the VP of marketing could do it type of easy) No user defined functions or subroutines. Its use would be in events of objects in a system similar to HyperCard. Conceptually I was thinking of a language like this: set myVariable to 'Hello World' set counter to 0 repeat 5 times with x begin set counter to counter add x end set myVariable to myVariable plus ' ' plus counter popup myVariable set text of label named 'label' to 'new text' set color of label named 'label' to blue The end result would popup a dialog with the contents Hello World 15 it would also change the text of a label and make it blue. But I could do the same thing 1000 different ways. So what makes one language any better than another when both are designed for the same goals?

• How can I use an object pool for optimization in AndEngine?

  - by coder_For_Life22

  I have read up on a tutorial that allows you to reuse sprites that are re-added to the scene such as bullets from a gun or any other objects using an ObjectPool. In my game i have a variation of sprites about 6 all together with different textures. This is how the object pool is set up with its own class extending Java's GenericPool class public class BulletPool extends GenericPool<BulletSprite> { private TextureRegion mTextureRegion; public BulletPool(TextureRegion pTextureRegion) { if (pTextureRegion == null) { // Need to be able to create a Sprite so the Pool needs to have a TextureRegion throw new IllegalArgumentException("The texture region must not be NULL"); } mTextureRegion = pTextureRegion; } /** * Called when a Bullet is required but there isn't one in the pool */ @Override protected BulletSprite onAllocatePoolItem() { return new BulletSprite(mTextureRegion); } /** * Called when a Bullet is sent to the pool */ @Override protected void onHandleRecycleItem(final BulletSprite pBullet) { pBullet.setIgnoreUpdate(true); pBullet.setVisible(false); } /** * Called just before a Bullet is returned to the caller, this is where you write your initialize code * i.e. set location, rotation, etc. */ @Override protected void onHandleObtainItem(final BulletSprite pBullet) { pBullet.reset(); } } As you see here it takes a TextureRegion parameter. The only problem i am facing with this is that i need to have 6 different sprites recycled and reused in the ObjectPool. This ObjectPool is set up to only use one TextureRegion. Any idea's or suggestions on how to do this?

• Upon Reflection

  - by foxjazz

  During my tenure at the last company, I didn't let my career stagnate as others have and as time moved along.When at work or home, spend 10% of your time learning something new about some aspect or segway of your job so that your skills are marketable in case you lose it. From experience let me reinforce that it pays off. It pays off in your current job because of the education received and the competence increase of your skills which applied will bring recognition.In these days and times, loyalty to a company is truly at an end. However many companies do care about cultivating their employees which creates a brand of loyalty that can't be replaced. Old companies with the Corp. mentality (or because of the corp. mentality) ever decrease their budgets on organizational sections and thereby do a RIF as a matter of business.The mistakes they make during this process can be risky. But who am I, but a lowly ole programmer, to judge risk. If you are laid off, be friendly with your past manager, and based on simple questions and help, give whatever help you can over the phone even though you are under no obligation to do so.It is also quite possible that there are opportunities to make at home with a new company in the future. Just remember that when inquiring about a position, take advantage of the training that is offered, and keep yourself emotionally and educationally fit.Talk soon,foxjazz

• what will EcmaScript 6 bring to the table for us

  - by user697296

  Our company ported moderate chunks of business logic to JavaScript. We compile the code with a minifier, which further improves performance. Since the language is dynamically typed, it lends itself well to obfuscation, which occurs as a byproduct of minification. We went to great efforts to ensure it positively screams, performance-wise. We can now do what we did before, faster, better, with less code, on more platforms. In summary, we are very satisfied with the current state of the language. I personally love the language especially for its cross-platform nature. So naturally, I read up a lot about the state of JavaScript compilers, performance and compatibility across as many browsers and platforms as I have time to research. The one theme which has been growing louder and louder these days, is the news about ECMAScript 6. So far, what I have been able to gather is that ES6 promises a better development experience; firstly by enabling new ways to do things, secondly by reporting errors early. This sounds great for those who are still waiting for the language to meet their needs before jumping on board. But we have already jumped on board in a big way. Sure, I expect that we will have to do ongoing maintenance and feature revisions on our code through the years, and that we would obviously make use of best practices at the time. But I don't see us refactoring major portions of it to take advantage of language features that are mostly intended to boost developer productivity. I keep wondering, what impact will the language advances ultimately have on our existing, well-written, well-performing code base? Is there something I am missing? Is there something we ought to look out for? Does anyone have tips or guidance on how we should approach the ecmascript.next finalization? Should we care?

• How to reset a List c# and XNA [on hold]

  - by P3erfect

  I need to do a "retry" option when the player finishes the game.For doing this I thought to reset the lists of Monsters and other objects that moved at the first playing or which have been "killed".for example I have a list like that: //the enemy1 class is already done // in Game1 I declare it List<enemy1> enem1 = new List<enemy1>(); //Initialize method List<enemy1> enem1 = new List<enemy1>(); //LoadContent foreach (enemy1 enemy in enem1) { enemy.Load(Content); } enem1.Add(new enemy1(Content.Load<Texture2D>("enemy"), new Vector2(5900, 12600))); //Update foreach (enemy1 enemy in enem1) { enemy.Update(gameTime); } //after being shoted the enemies disappear and i remove them //if the monsters are shoted the bool "visible" goes from false to true for (int i = enem1.Count - 1; i >= 0; --i) { if (enem1[i].visible == true) enem1.RemoveAt(i); } //Draw foreach (enemy1 enemy in enem1) { if(enemy.visble==false) { enemy.Draw(spriteBatch, gameTime); } } //So my problem is to restart the game. I did this in Update method if(lost==false) { //update all the things... } if(lost==true)//this is if I die { //here I have to put the code that restore the list //I tried: foreach (enemy1 enemy in enem1) { enemy.visible=false; } player.life=3;//initializing the player,points,time player.position=initialPosition; points=0; time=0; }//the player works.. } } they should be drawn again but if I removed them they won't be drawn anymore.If I don't remove them ,instead, the enemies are in different places (because they follow me). Any suggestions to restore or reinitialize the list??

• Reversing animated sprites

  - by brandon sedgwick

  I have created a sprite sheet of which consists of 6 frames with a character moving legs each frame, now I have coded it so that the animation is running successfully from frame 1 to 6, however I am trying to reverse this so then when it goes from 1 to 6 instead of restarting it go's 6 to 1 in a continuous loop. The coding for current animation is: void SpriteGame::Update(int tickTotal, int tickDelta) { //This is where you manage the state of game objects if ( tickTotal >= this->playerLastFrameChange + 4) { //Four ticks have elapsed since the last frame change this->playerFrame = this->playerFrame + 1; this->playerLastFrameChange = tickTotal; //We've just changed the frame if (this->playerFrame >= this->playerSheetLength) { this->playerFrame = playerLastFrameChange + 4; } //Frame has changed so change the source rectangle this->playerSourceRect->left = this->playerFrame * 64; this->playerSourceRect->top = 0; this->playerSourceRect->right = (this->playerFrame + 1) * 64; this->playerSourceRect->bottom = 64; } } any help please I am using DirectX11 as thats what we are being told to use as its for an win 8 game.

• What service or software should I use to serve advertising on a site with about 120k monthly page views?

  - by JasonBirch

  I have a site that is generating about 120k monthly page views and is being hosted on a shared FreeBSD server where I have access to PHP and MySQL. I am using some custom PHP server-side scripts that give each of my ad networks (AdSense, Tribal Fusion, etc) an adjustable percentage of impressions in each of the ad positions on my pages. I am looking for a better way of managing and measuring the delivery of these ads, and would also like to be able to take direct placements and provide statistics to the clients. I am looking at options including OpenX self-hosted, OpenX community, and Google DoubleClick for Publishers Small Business (DFP), but am having difficulty determining which one will best meet my needs. They all seem to have pretty steep learning curves compared to my simple scripts. What I have taken away so far as the benefit of self-hosting is that I don't have to pay for the service if I exceed a maximum number of ad impressions, while both OpenX Community and DFP have free impression limits. Of course, if I was doing those kind of numbers I'd need to upgrade my hosting account, but I'm not sure even at that point whether it would be cheaper to serve the ads myself than pay for a premium service. Apart from this, I really need insights into what features differentiate these services, why I might want to choose one over another, and if there are any other competing products or service of the same quality that I should look into. Answers from webmasters who have used both (or all three) services and can talk to usability and ease of ad management would be highly appreciated.

• Best approach for tracking dependent state

  - by Pace

  Let's pretend I work on a project tracking application. The application is a database backed, server hosted, web application. In this application there are Projects which have many Activities which have many Tasks. A Task has two date fields an originalDueDate and a projectedDueDate. In addition, there are dynamic fields on the Activities and the Projects which indicate whether the Activity or Project is behind schedule based on the projected due dates of the child tasks and various other variables such as remaining buffer time, etc. There are a number of things that can cause the projectedDueDate to change. For example, an employee working on the project may (via a server request) enter in a shipping delay. Alternatively, a site may (via a server request) enter in an unexpected closure. When any of these things occur I need to not only update the projectedDueDate of the Task but also trigger the corresponding Project and Activity to update as well. What is the best way to do this? I've thought of the observer pattern but I don't keep a single copy of all these objects in memory. When a request comes in, I query the Task in from the database, at that point there is no associated Activity in memory that would be a listener. I could remove the ability to query for Tasks and force the application to query first by Project, then by Activity (in context of Project), then by task (in context of Activity) adding the observer relationships at each step but I'm not sure if that is the best way. I could setup a database event listening system so when a Task modified event is dispatched I have a handler which queries for the Activity at that point. I could simply setup a two-way relationship between Task and Activity so that the Task knows about the parent Activity and when the Task updates his state the Task grabs his parent and updates state. Right now I'm stuck considering all the options and am wondering if any single approach (doesn't have to be a listed approach) is jumping out at others as the best approach.

• Re: # 47209 How to copy an Existing HD to a new one and have it be bootable?

  - by user281151

  Help please! My backup method of choice is to clone my "working" drive to another identical drive. I have 2 windows drives and I clone my working one to the other one once per month. No problem - each will boot if I select it. Now with the lack of future support for XP, I am getting familiar with Ubuntu 14.04 LTS. I have it on one drive and I have a second identical drive that I want to be able to clone it to once/month. Not as necessary to do this with Ubuntu as with windows, I know, but I'm anal. So I have followed #47209 MestreLion's procedure with just the two Ubuntu drives "on line". I.e., boot my "working" drive with Live CD, use Gparted to be sure I know what's what, open terminal and enter and execute the dd command, Go to bed till the clone is done, shut down the computer, disconnect the input/source drive, boot up using BIOS to select the remaining output drive. The drive starts fine but all is not OK. It puts up a screen that says I'm on a Guest Session and asks for a password. Well, for one thing I have my Ubuntu set up to start without a password being entered. I have one, of course, I put it in but it isn't accepted. I can't get by this Guest Session screen. I am fine, of course. I can disconnect this drive, hook up my "main" ubuntu drive and all the rest, and go on with my business. But I don't have the desired "emergency backup" drive working where I could jump on and use it immediately if I needed it. Can someone give me some guidance here?? What (else) do I need to do. Love Ubuntu but learning. Thanks, Wes.

• Windows Phone 7 v. Windows 8 Metro &ldquo;Same but Different&rdquo;

  - by ryanabr

  I have been doing development on both the Windows Phone 7 and Windows 8 Metro style applications over the past month and have really been enjoying doing both. What is great is that Silverlight is used for both development platforms. What is frustrating is the "Same but Different" nature of both platforms. Many similar services and ways of doing things are available on both platforms, but the objects, namespaces, and ways of handling certain cases are different. I almost had a heart attack when I thought that XmlDocument had been removed from the new WinRT. I was relived (but a little annoyed)  when I found out that it had shifted from the "System.Xml" namespace to the "Windows.Data.Xml.Dom" namespace. In my opinion this is worse than deprecating and reintroducing it since there isn't the lead time to know that the change is coming, maker changes and adjust. I also think the breaks the compatibility that is advertised between the WinRT and .NET framework from a programming perspective, as the code base will have to be physically different if compiled for one platform versus the other. Which brings up another issue, the need for separate DLLs with for the different platforms that contain the same C# code behind them which seems like the beginning of a code maintenance headache. Historically, I have kept source files "co-located" with the projects that they are compiled into. After doing some research, I think I will end up keeping "common" files that need to be compiled in to DLLs for the different platforms in a seperate location in TFS, not directly included in any one Visual Studio project, but added as links in the project that would get compiled into the windows 7 phone, or Windows 8. This will work fine, except for the case where dependencies don't line up for each platform as described above, but will work fine for base classes that do the raw work at the most basic programming level.

• decouple software components via nameconvention

  - by csteinmueller

  I'm currently evaluating alternatives to refactor a drivermanagement. In my multitier architecture I have Baseclass DAL.Device //my entity Interfaces BL.IDriver //handles the dataprocessing between application and device BL.IDriverCreator //creates an IDriver from a Device BL.IDriverFactory //handles the driver creation requests Every specialization of Device has a corresponding IDriver implementation and a corresponding IDriverCreator implementation. At the moment the mapping is fix via a type check within the business layer / DriverFactory. That means every new driver needs a) changing code within the DriverFactory and b) referencing the new IDriver implementation / assembly. On a customers point of view that means, every new driver, used or not, needs a complex revalidation of their hardware environment, because it's a critical process. My first inspiration was to use a caliburn micro like nameconvention see Caliburn.Micro: Xaml Made Easy BL.RestDriver BL.RestDriverCreator DAL.RestDevice After receiving the RestDevicewithin the IDriverFactory I can load all driver dlls via reflection and do a namesplitting/comparing (extracting the xx from xxDriverCreator and xxDevice) Another idea would be a custom attribute (which also leads to comparing strings). My question: is that a good approach above layer borders? If not, what would be a good approach?

• How should I structure the implementation of turn-based board game rules?

  - by Setzer22

  I'm trying to create a turn-based strategy game on a tilemap. I'm using design by component so far, but I can't find a nice way to fit components into the part I want to ask. I'm struggling with the "game rules" logic. That is, the code that displays the menu, allows the player to select units, and command them, then tells the unit game objects what to do given the player input. The best way I could thing of handling this was using a big state machine, so everything that could be done in a "turn" is handled by this state machine, and the update code of this state machine does different things depending on the state. However, this approach leads to a large amount of code (anything not model-related) going into a big class. Of course I can subdivide this big class into more classes, but it doesn't feel modular and upgradable enough. I'd like to know of better systems to handle this in order to be able to upgrade the game with new rules without having a monstruous if/else chain (or switch / case, for that matter). Any ideas? What specific design pattern other than MVC should I be using?

• More Win 8 Education is Needed

  - by D'Arcy Lussier

  “My mail doesn’t work”. That’s what a colleague running Windows 8 said to me the day after he installed Windows 8 on his work laptop. “When I click my email, nothing comes up.” I took a look and realized what was going on – he was clicking the Windows 8 UI Mail app and assumed that this was somehow connected to his Outlook which was installed as a desktop app. And so highlights a major educational challenge that Windows 8 will encounter – millions of users used to one style of interface now being introduced to a new one that runs side-by-side with their desktop. At work we had an internal tech user group meeting, and we were showing new features of VS.NET 2012 and Windows 8. When we started talking about the difference between Windows 8 UI Apps (AKA Windows Store Apps), people started asking some good questions: - Can we share a codebase between desktop and Windows Store Apps? - What’s the difference between WinRT and .NET? - Why would we create a Windows Store App and not just a Desktop app? Of course, people are looking at this from a traditional desktop point of view and not a tablet platform, which is really the market that Windows Store Apps will shine on. Still, for developers who not only need to educate themselves but also educate their clients, we’re going to need a better understanding of Windows 8 to see it get real traction within the business/enterprise market.

• How to persuade C fanatics to work on my C++ open source project?

  - by paperjam

  I am launching an open-source project into a space where a lot of the development is still done Linux-kernel-style, i.e. C-language with a low-level mindset. There are multiple benefits to C++ in our space but I fear those used to working in C will be scared off. How can I make the case for the benefits of C++? Specifically, the following C++ attributes are very valuable: concept of objects and reference-counting pointers - really don't want to have to malloc(sizeof(X)) or memcpy() structs templates for specialising whole bodies of code with specific performance optimizations and for avoiding duplication of code. template metaprogramming related to the above syntactic sweetness available (e.g. operator overloading, to be used in very small doses) STL Boost libraries Many of the knee-jerk negative reactions to C++ are illfounded. Performance does not suffer: modern compilers can flatten dozens of call stack levels and avoid bloat through wide use of template specializations. Granted, when using metaprogramming and building multiple specializations of a large call tree, compile time is slower but there are ways to mitigate this. How can I sell C++?

  - by beginner_

  I have at first sight a simple issue but can't wrap my head around on how to solve. I have an abstract class Compound. A Compound is made up of Structures. Then there is also a Container which holds 1 Compound. A "special" implementation of Compound has Versions. For that type of Compound I want the Container to hold the Versionof the Compound and not the Compound itself. You could say "just create an interface Containable" and a Container holds 1 Containable. However that won't work. The reason is I'm creating a framework and the main part of that framework is to simplify storing and especially searching for special data type held by Structure objects. Hence to search for Containers which contain a Compound made up of a specific Structure requires that the "Path" from Containerto Structure is well defined (Number of relationships or joins). I hope this was understandable. My question is how to design the classes and relationships to be able to do what I outlined.

• Getting Requirements Right

  - by Tim Murphy

  Originally posted on: http://geekswithblogs.net/tmurphy/archive/2013/10/28/getting-requirements-right.aspxI had a meeting with a stakeholder who stated “I bet you wish I wasn’t in these meetings”.  She said this because she kept changing what we thought the end product should look like.  My reply was that it would be much worse if she came in at the end of the project and told us we had just built the wrong solution. You have to take the time to get the requirements right.  Be honest with all involved parties as to the amount of time it is taking to refine the requirements.  The only thing worse than wrong requirements is a surprise in budget overages.  If you give open visibility to your progress then management has the ability to shift priorities if needed. In order to capture the best requirements use different approaches to help your stakeholders to articulate their needs.  Use mock ups and matrix spread sheets to allow them to visualize and confirm that everyone has the same understanding.  The goals isn’t to record every last detail, but to have the major landmarks identified so there are fewer surprises along the way. Help the team members to understand that you all have the same goal.  You want to create the best possible solution for the given business problem.  If you do this everyone involved will do there best to outline a picture of what is to be built and you will be able to design an appropriate solution to fill those needs more easily.
