  • How do you manage feature requests and software changes?

    - by 0A0D
    I am a Software Engineer and over the past few years I have become the de-facto software project manager simply because there isn't one. So to keep our sanity in the R&D/Engineering department, customers have become accustomed to coming to me with their requests. I have no experience in this realm so it is my first time acting as a project manager for software projects. I have managed other things but not software. So, how do you manage software projects and mark priorities? Requests come in at infrequent intervals so we very well could be working on something for someone else and then another person comes in with a "rush" job that needs working on. Is it easier to just say First Come, First Serve or is it the person with the most money?

  • Company wants to write custom project management tool, rather then use third party product.

    - by Jason Evans
    At the company I work, we are really wanting to get into the agile methodology for developing software. One thing that I'm not excited about is the fact that management wants us to build a custom project management feature inside the company's Intranet. I think this is a total waste of time. There are many great third party tools available (e.g. Axosoft OnTime) that can do everything we need, and more. For how much development time it would cost us to build our own project management module, we could buy numerous licences for a third party product. One concern is that, whilst we are writing code for a client, and using our custom Intranet project management module, we find bugs in the module that need fixing ASAP. That means having to stop work on the client code to fix the Intranet. That just puts shivers down my spine. Another worry I have is lack of functionality. This custom module is going to be so basic, that it will just feel really crap to use. That might sound a bit snooty, but for goodness sake, many third party tools are so feature rich, that the idea of having to write our own tool makes feel very uneasy. In fact, I can't be bothered. What do you guys think? I'm going to raise this issue with my boss, since I feel it's such an important topic to talk about. EDIT: Thanks for the great responses, much appreciated. To summarize some of them: Money Naturally my boss does want to save money, by not forking out a few hundred £'s for licences. However, for us to write a custom tool, it will take x number of days, multiplied by approx £500, which is our costs. I don't see the business value in this. Management have mentioned that they want to sell the Intranet as a product in the future, but it's so custom to our needs (and downright basic), that in order to give it to another client, I can see us having to fork a version of the code and rebuild the majority of it anyway. So it's not like we're gaining anything there in reuse. Features Having our own custom module means not feature bloat - only the functionality we require will be in the product. My issue is that there are plenty of free, open-source project management tools out there with minimal features already. So even if cost is an issue, we could look into open-source. Again it all boils down to the fact that I don't see the point in writing a project management tool in this day and age. It's a bit like writing your own web browser - why?, what's the point? Although management are asking for this tool, just because they are, it does not mean I'm going to please them and do it just because they asked for it. If something does not make sense, then I will raise it as a concern. At the end of the day, it's the developers who write the code, it's the developers who make money for a business. Thus, as far I'm concerned, the devs have a very big role in deciding how a company should manage projects and what tools are used. "I am Spartan, argh!" :) Hmm, I've not been able to make this question a wiki for some reason, thus I'm going to have to pick an answer to accept. Cheers. Jas.

  • MS Word Macro in visual Basic

    - by Mac
    I have a Visual Basic system that in places runs word macros. I now need to have a MS Word Macro that I can search for a character and then extend the search to another character and extract the details into a vb variable from the first to the last character. Thereafter I need to search for the next occurrence of the first character and repeat the exercise. When all have been processed the last search must inform me that there are no more. During the searches I need to identify the section numbers where I find the searches and be able to get them in VB variable. Any assistance will be greatly appreciated. Regards Mac

  • Should custom data elements be stored as XML or database entries?

    - by meteorainer
    There are a ton of questions like this, but they are mostly very generalized, so I'd like to get some views on my specific usage. General: I'm building a new project on my own in Django. It's focus will be on small businesses. I'd like to make it somewhat customizble for my clients so they can add to their customer/invoice/employee/whatever items. My models would reflect boilerplate items that all ModelX might have. For example: first name last name email address ... Then my user's would be able to add fields for whatever data they might like. I'm still in design phase and am building this myself, so I've got some options. Working on... Right now the 'extra items' models have a FK to the generic model (Customer and CustomerDataPoints for example). All values in the extra data points are stored as char and will be coerced/parced into their actual format at view building. In this build the user could theoretically add whatever values they want, group them in sets and generally access them at will from the views relavent to that model. Pros: Low storage overhead, very extensible, searchable Cons: More sql joins My other option is to use some type of markup, or key-value pairing stored directly onto the boilerplate models. This coul essentially just be any low-overhead method weather XML or literal strings. The view and form generated from the stored data would be taking control of validation and reoganizing on updates. Then it would just dump the data back in as a char/blob/whatever. Something like: <datapoint type='char' value='something' required='true' /> <datapoint type='date' value='01/01/2001' required='false' /> ... Pros: No joins needed, Updates for validation and views are decoupled from data Cons: Much higher storage overhead, limited capacity to search on extra content So my question is: If you didn't live in the contraints impose by your company what method would you use? Why? What benefits or pitfalls do you see down the road for me as a small business trying to help other small businesses? Just to clarify, I am not asking about custom UI elements, those I can handle with forms and template snippets. I'm asking primarily about data storage and retreival of non standardized data relative to a boilerplate model.

  • Business layer access to the data layer

    - by rerun
    I have a Business layer (BL) and a Data layer (DL). I have an object o with a child objects collection of Type C. I would like to provide a semantics like the following o.Children.Add("info"). In the BL I would like to have a static CLASS that all of business layer classes uses to get a reference to the current datalayer instance. Is there any issue with that or must I use the factory pattern to limit creation to A class in the BL that knows the DL instance.

  • Is Windows 7 written in Xaml? [closed]

    - by Jordan
    Is Windows 7 written using Xaml? Edit Wow, so much hate for such a little question. I'm not an idiot. I know what XAML is. I use it every day. I was just curious whether some of the visual features were laid out with XAML, or if XAML was incorporated in some way to the product. I'm sorry if it is a programming sin not to know what Windows 7 was written in. I mean, I know Windows XP et al used C++/C, I've used Win32 quite a lot (and MFC and .NET).

  • Internal and external API architecture

    - by Tacomanator
    The company I work for maintains a successful SaaS product that grew "organically" over the years. We are planning to expand the line with a suite of new products that will share data with the existing product. To support this, we are looking to consolidate business logic into a single place: a web service layer. The WS layer will be used by: The web applications A tool to import data A tool to integrate with other client software (not an API per se) We also want to create an API that can be used by our customers that are capable of using it to create their own integrations. We are struggling with the following question: Should the internal API (aka the WS layer) and the external API be one in the same, with security and permission settings to control what can be done by who, or should they be two separate applications where the external API just calls the internal API like any other application? So far in our debate it seems that separating them may be more secure, but will add overhead. What have others done in a similar situation?

  • Can you point me to a nontrivial strategy pattern implementation?

    - by Eugen Martynov
    We are faced implementing a registration workflow with many branches. There are three main flows which in some conditions lead to one another. Each flow has at least four different steps; some steps interact with the server, and every step adds more information to the state. Also the requirement is to have it persistent between sessions, so if the user closes the app (this is a mobile app), it will restore the process from the last completed step with the state from the previous session. I think this could benefit from the use of the strategy pattern, but I've never had to implement it for such a complex case. Does anyone know of any examples in open source or articles from which I could find inspiration? Preferably the examples would be from a live/working/stable application. I'm interested in Java implementation mostly; we are developing for Java mobile phones: android, blackberry and J2ME. We have an SDK which is quite well separated from platform specific implementations, but examples in C++, C#, Objective-C or Python would be acceptable.

  • Why aren't there automated translators from one programming language to another?

    - by serg
    Most programming languages are Turing complete, which means that any task that can be solved in one language can be solved in another one, or even on Turing machine. Then why aren't there automatic translators that can convert programs from any given language to any other language? I've seen couple attempts for two languages, but they always work only on a limited subset of a language and can hardly be used for converting real projects. Is it possible, at least in theory, to write 100% correct translator between all languages? What are the challenges in practice? Are there any existing translators that work?

  • What layer to introduce human readable error messages?

    - by MrLane
    One of the things that I have never been happy with on any project I have worked on over the years and have really not been able to resolve myself is exactly at what tier in an application should human readable error information be retrieved for display to a user. A common approach that has worked well has been to return strongly typed/concrete "result objects" from the methods on the public surface of the business tier/API. A method on the interface may be: public ClearUserAccountsResult ClearUserAccounts(ClearUserAccountsParam param); And the result class implementation: public class ClearUserAccountsResult : IResult { public readonly List<Account> ClearedAccounts{get; set;} public readonly bool Success {get; set;} // Implements IResult public readonly string Message{get; set;} // Implements IResult, human readable // Constructor implemented here to set readonly properties... } This works great when the API needs to be exposed over WCF as the result object can be serialized. Again this is only done on the public surface of the API/business tier. The error message can also be looked up from the database, which means it can be changed and localized. However, it has always been suspect to me, this idea of returning human readable information from the business tier like this, partly because what constitutes the public surface of the API may change over time...and it may be the case that the API will need to be reused by other API components in the future that do not need the human readable string messages (and looking them up from a database would be an expensive waste). I am thinking a better approach is to keep the business objects free from such result objects and keep them simple and then retrieve human readable error strings somewhere closer to the UI layer or only in the UI itself, but I have two problems here: 1) The UI may be a remote client (Winforms/WPF/Silverlight) or an ASP.NET web application hosted on another server. In these cases the UI will have to fetch the error strings from the server. 2) Often there are multiple legitimate modes of failure. If the business tier becomes so vague and generic in the way it returns errors there may not be enough information exposed publicly to tell what the error actually was: i.e: if a method has 3 modes of legitimate failure but returns a boolean to indicate failure, you cannot work out what the appropriate message to display to the user should be. I have thought about using failure enums as a substitute, they can indicate a specific error that can be tested for and coded against. This is sometimes useful within the business tier itself as a way of passing via method returns the specifics of a failure rather than just a boolean, but it is not so good for serialization scenarios. Is there a well worn pattern for this? What do people think? Thanks.

  • Identifying the best pattern

    - by Daniel Grillo
    I'm developing a software to program a device. I have some commands like Reset, Read_Version, Read_memory, Write_memory, Erase_memory. Reset and Read_Version are fixed. They don't need parameters. Read_memory and Erase_memory need the same parameters that are Length and Address. Write_memory needs Lenght, Address and Data. For each command, I have the same steps in sequence, that are something like this sendCommand, waitForResponse, treatResponse. I'm having difficulty to identify which pattern should I use. Factory, Template Method, Strategy or other pattern.

  • What are the preferred documentation tools for the major programming languages?

    - by Dave Peck
    I'm interested in compiling a list of major programming languages and their preferred documentation toolsets. To scope this a bit: The exact structure of the answer may vary from language to language, but there appear to be two aspects common to all languages: (1) in-code syntax for documentation, and (2) documentation generators that make use of said syntax. There are also cases where generators are used independent of code. For example, tutorial-style documentation is common in the Python world and is often disconnected from underlying code. Many languages have multiple commonly-used documentation strategies and tool chains, and I'd love to capture this. Finally, there are cross-language tools like Doxygen that also have some traction and would be worth noting here. Here are some obvious target languages to start with: Python, Ruby, Java, C#, PHP, Objective-C, C/C++, Haskell, Erlang, Scala, Clojure If this question catches on, I'll try and keep this section updated with the most recent list. Thanks!

  • Mono is frequently used to say "Yes, .NET is cross-platform". How valid is that claim?

    - by Thorbjørn Ravn Andersen
    In What would you choose for your project between .NET and Java at this point in time ? I say that I would consider the "Will you always deploy to Windows?" the single most important decision to make up front in a new web project, and if the answer is "no", I would recommend Java instead of .NET. A very common counter-argument is that "If we ever want to run on Linux/OS X/Whatever, we'll just run Mono", which is a very compelling argument on the surface, but I don't agree for several reasons. OpenJDK and all the vendor supplied JVM's have passed the official Sun TCK ensuring things work correctly. I am not aware of Mono passing a Microsoft TCK. Mono trails the .NET releases. What .NET-level is currently fully supported? Does all GUI elements (WinForms?) work correctly in Mono? Businesses may not want to depend on Open Source frameworks as the official plan B. I am aware that with the new governance of Java by Oracle, the future is unsafe, but e.g. IBM provides JDK's for many platforms, including Linux. They are just not open sourced. So, under which circumstances is Mono a valid business strategy for .NET-applications?

  • Information Spilling Across Object Boundaries

    - by Winston Ewert
    Many times my business objects tend to have situations where information needs to cross object boundaries too often. When doing OO, we want information to be in one object and as much as possible all code dealing with that information should be in that object. However, business rules do not follow this principle giving me trouble. As an example suppose that we have an Order which has a number of OrderItems which refers to an InventoryItem which has a price. I invoke Order.GetTotal() which sums the result of OrderItem.GetPrice() which multiples a quantity by InventoryItem.GetPrice(). So far so good. But then we find out that some items are sold with a two for one deal. We can handle this by having OrderItem.GetPrice() do something like InventoryItem.GetPrice( quantity ) and letting InventoryItem deal with this. However, then we find out that the two-for-one deal only lasts for a particular time period. This time period needs to be based on the date of the order. Now we change OrderItem.GetPrice() to be InventoryItem.GetPrice( quatity, order.GetDate() ) But then we need to support different prices depending on how long the customer has been in the system: InventoryItem.GetPrice( quantity, order.GetDate(), order.GetCustomer() ) But then it turns out that the two-for-one deals apply not just to buying multiple of the same inventory item but multiple for any item in a InventoryCategory. At this point we throw up our hands and just give the InventoryItem the order item and allow it to travel over the object reference graph via accessors to get the information its needs: InventoryItem.GetPrice( this ) TL;DR I want to have coupling in objects, but business rules often force me to access information from all over the place in order to make particular decisions. Are there good techniques for dealing with this? Do others find the same problem?

  • What do you do about content when someone asks you to build a website

    - by Jon
    I am an experienced asp.net developer and asp.net mvc and I have my own CMS that I have written but starting to think there should be another approach. When someone asks you to develop them a website how do you develop it so that they can add pictures,slideshows, content, news items, diary events. On a side note do you give them a design for the home page and inner page and thats it. I'm just thinking if they turn around and say 6 months down the line I want a jquery slideshow on the right hand side of this page how do you or CMS's handle it?

  • Solutions for software using many calls to a server

    - by Val
    I am developing software that uses many calls to a server. On a client side it's a Silverlight application. Almost every time a user clicks on a button in it, it sends 1-5 WCF calls to a server. There can be up to dozen or so users at a time. The server is a database server that serves data to a client. I am an intermediate level developer and am thinking about caching some data and syncing my changes from time to time. Are there any official solutions or technologies for it, like, patterns and such?

  • using a wiki for requirements

    - by apollodude217
    Hi, I'm looking into ways of improving requirements management. Currently, we have a Word document published on a Web site. Unfortunately, we cannot (to my knowledge) look at changes from one revision to the next. I would greatly prefer to be able to do so, much like with a wiki or VCS (or both, like the wiki's on bitbucket!). Also, each document describes changes devs are expected to meet by a given deadline. There is no collection of accumulated app features documented anywhere, so it's sometimes hard to distinguish between a bug and a (poorly-designed) feature when trying to make quick fixes to legacy apps. So I had an idea I wanted to get feedback on. What about: Using a wiki so that we can track who changed what when (mostly to even see if any edits were made since the last time one looked). Having one, say, wiki page per product rather than one per deadline, keeping up with all features of the product rather than the changes that should be implemented. This way, I can look at a particular revision of the page to see what the app should do at a given point in time, and I can look at changes to the page since the last release for the requirements to be implemented by the next deadline. Waddayathink?

  • I'm porting my app from iOS to Android: what do I need to know?

    - by kubi
    What pitfalls should I avoid? What Java language paradigms do Objective-C developers consistently misunderstand? I learned to program in Java, but I have worked in nothing but Objective-C for years now. How are the design patterns different between Android and iOS? If you've made the transition yourself, what parts of Android confused you or took you longer to learn than it should have? Is Eclipse the best OS X IDE for Android? For the record, my app is very strongly tied to UIKit and Foundation, so the word "porting" may be a misnomer; I'll actually be completely rewriting it for Android. No code reuse. Also, I'm doing this to learn Android, so I'd rather fail at the port and learn Android than take a shortcut.

  • Best industry to work for as a developer.

    - by The Elite Gentleman
    Hi guys, Hmmm, StackOverflow now warns me of: "The question you're asking appears subjective and is likely to be closed." I've been an avid java (J2SE, JEE) developer for over 5 years now (and I'm not complaining, even though I want to go back to Delphi & C++). My contract has just ended and I'm wondering of possible job to further tackle. I've done banking and insurance industry for all my career (with 1 year on a Fortuner 500 company) and pretty much, banking is the slowest (and boring) industry to work for (IMHO) since they're strict in their business practices (fair enough). The upside is that they pay. My question is: What is the best industry for a developer, who tends to get bored relatively quickly, to work for? Is it also worthwhile for me to do consultancy (and if so, what type of consultancy)? PS There's no gaming industry in South Africa, so suggesting it requires that I have to travel to a country where gaming is alive! I don't see the Community Wiki checkbox, so I don't know how to make this a wiki.
