• Solutions for Project management [closed]

  - by user14416

  The team consists of 3 people. The method of development is Scrum. The language of the project is C++. The project will be under the control of the git system. The start up budget is 0. The following things have to be chosen: Build and Version Numbering Project documentation ( file with the most common info for current stage of the project, which will be changed every time the new version or subversion of the project emerges ) Project management tool ( like Trac or Redmine, I cannot use them, because there is no hosting ) Code documentation ( I consider Doxygen ) The following questions have arisen: What can you add to the above list of the main solutions for project management in the described project? One of three project participants has linux os (No MS Office), one has Windows and MS Office (does not want to use Libre or Open Office), one has Windows, but does not have MS Office. What formats, tools can u suggest using for project documentation? The variant of using online wiki does not fit, it must be files. OneNote mb is a good tool for project management, but because of the reason mentioned above it is not possible. What can you advise? Offer a system for Build and Version Numbering.

• Where is it permissible to add logging code in a MVC model?

  - by BDotA

  Working on a C# WinForms program that is written in a MVC ( actually Model-View-Presenter) style and I want to add a few lines of code that is responsible for logging some events. Where should I write two or three lines of code that I need? Should I write it in the Presenter section? To get an idea, here is some lines of sample code that already exists in the Save() metohd in Company.MyApplication.Presenter.MyPresenter.cs class: he has written codes lie the following in this part of presenter: private void Save(Helper.SaveStatusEnum status) { if (notification.CheckLocks(orderIdCollection)) { using (new HourglassController()) { controller.FireActiveCellLeaving(); ViewDocumentedValues(); int result = saveController.Save(status); if (result == Helper.SAVE_SUCCESSFUL) { // IS IT OK TO WRITE MY COUPLE LINES OF CODE IN HERE??????????? model.Dirty = false; if ((model.CurrentStatus == Helper.OrderStatusEnum.Complete) || (model.CurrentStatus == Helper.OrderStatusEnum.Corrected)) { controller.EnableDisableSheet(false); } CheckApplicationState(); SheetHelper.ClearUnsavedDataRowImage(view.ActiveSheet); } else { MessageBox.Show("An unexpected error occuring trying to save."); } } } }

• What to Return with Async CRUD methods

  - by RualStorge

  While there is a similar question focused on Java, I've been in debates with utilizing Task objects. What's the best way to handle returns on CRUD methods (and similar)? Common returns we've seen over the years are: Void (no return unless there is an exception) Boolean (True on Success, False on Failure, exception on unhandled failure) Int or GUID (Return the newly created objects Id, 0 or null on failure, exception on unhandled failure) The updated Object (exception on failure) Result Object (Object that houses the manipulated object's ID, Boolean or status field to with success or failure indicated, Exception information if there was one, etc) The concern comes into play as we've started moving over to utilizing C# 5's Async functionality, and this brought the question up of how we should handle CRUD returns large-scale. In our systems we have a little of everything in regards to what we return, we want to make these returns standardized... Now the question is what is the recommended standard? Is there even a recommended standard yet? (I realize we need to decide our standard, but typically we do so by looking at best practices, see if it makes sense for us and go from there, but here we're not finding much to work with)

• Why is it so hard to find anything on MS site?

  - by Amir Rezaei

  I have always had this question in my mind and I would really be happy to get an explanation for this. Is it only me or do you also feel the same way that it's hard to find anything on MS site. For example, every time I need to download .NET framework I have to Google it. You never know what you can download, no category for downloads. You are simply left to a search field. You never know if you downloaded the latest version of the file. The tragically true is that you have to rely on their competitor Google to find anything on their site. I know that they are a big company. But is it really that hard to have an organized way to publish information?

• What is the role of traditional issue tracker when Scrum / Kanban board is used?

  - by Borek

  From a very high level view, to me it seems there are generally 2 types of Project Management tools: Traditional issue trackers like Fogbugz, JIRA, BugZilla, Trac, Redmine etc. Virtual card boards / agile project management tools like Pivotal Tracker, GreenHopper, AgileZen, Trello etc. Sure, they overlap in one way or another, e.g. Pivotal Tracker tasks can be imported to JIRA, GreenHopper itself is implemented on top of JIRA issue base etc. but I think one can still see the difference in orientation between those two types of tools. Traditional issue tracker seems to be used even in companies otherwise doing agile project management. My question is, why do they do that? I also feel that we should use an issue tracker in my company but when I'm thinking about it, I'm not actually sure why should we need it. For example, Trello development seems to be managed by using Trello itself (see this virtual wall) even though they have access to Fogbugz, one of the best issue trackers around. So maybe we don't need traditional issue tracker when we'll be doing 100% of our work in an agile manner using one of the agile PM tools?

• airplanes operating system and choice of programing language

  - by adhg

  I was wondring if anyone knows what is the operating system used in commercial airplanes (say Boeing or Airbus). Also, what is the (preferred) real-time programing language? I heard that Ada is used in Boeing, so my question is - why Ada? what are the criteria the Boeing-guys had to choose this language? (I guess Java wouldn't be a great choice if the exactly in lift off the garbage collector wakes up). Thanks!

• null values vs "empty" singleton for optional fields

  - by Uko

  First of all I'm developing a parser for an XML-based format for 3D graphics called XGL. But this question can be applied to any situation when you have fields in your class that are optional i.e. the value of this field can be missing. As I was taking a Scala course on coursera there was an interesting pattern when you create an abstract class with all the methods you need and then create a normal fully functional subclass and an "empty" singleton subclass that always returns false for isEmpty method and throws exceptions for the other ones. So my question is: is it better to just assign null if the optional field's value is missing or make a hierarchy described above and assign it an empty singleton implementation?

• Duplication of code (backend and javascript - knockout)

  - by Michal B.

  We have a new developer in our team. He seems a smart guy (he just came in so I cannot really judge). He started with implementing some small enhancements in the project (MVC3 web application using javascript - jquery and knockout). Let's say we have two values: A - quite complex calculation C - constant B = A + C On the screen there is value B and user can change it (normal texbox). When B changes, A changes as well because C is constant. So there is linear dependency between A and B. Now, all the calculations are done in the backend, but we need to recalculate A as user changes B (in js, I would use knockout). I thought about storing old A and B and when B changes by 10 then we know that new A will be old A + 10. He says this is dirty, because it's duplication of code (we make use of the fact that they are dependent and according to him that should be only in one place in our app). I understand it's not ideal, but making AJAX request after every key press seems a bit too much. It's a really small thing and I would not post if we haven't had long discussion about it. How do you deal with such problems? Also I can imagine that using knockout implies lots of calculations on the client side, which very often leads to duplication of the same calculations from the backend. Does anyone have links to some articles/thoughts on this topic?

• What is a good support knowledge base tool?

  - by Guillaume

  I have been searching for a tool to help my team organize its knowledge for resolving recurring support cases. I know this question will probably be closed, but I'll try my change anyway because I know that I can have some good answers about that. Context: our team is developing and supporting an huge applications (lots of different screens and workflow processes. We already have a good tool for managing our documentation, but we are struggling with support cases. Support action involve often quite a lot of manual steps to fix stuff and the knowledge for these actions is more 'oral transmission' than modern tools. We need an efficient way to store them in a knowledge base to be able to retrieve similar cases based on patterns (a stacktrace, an error message, a component name, a workflow step, ...) and ranked by similarity. Our wiki search is not very powerful when it come to this kind of search and the team members don't want to 'waste' time writing a report that will never be found... Do you know efficient knowledge base tool for this kind of use case ?

• What's the best project management software for internal dev. 5 man shop

  - by P.Brian.Mackey

  I work for a large corporation, but we do small intranet web application development. Our project management tracking sucks. Its custom software built by a jr. intern. For what its worth, our development style is akin to agile, but there's nothing set in stone...very customer oriented approach. I need project tracking that meets the criteria: Intranet, internal products. Mostly maintenance, some new development. 5 developers 12 products 1 hands-off manager. He really just wants to know estimated man hours, due date for dev, QA and release. Along with a short description of the project. Free or super cheap. Bonus Simple pretty UI. Think pretty charts. Hope I covered everything. Please ask for any clarification. If you read dreaming in code, the company uses some project tracking software that sounds pretty sweet. Note, we do have Team Foundation Server. I already tried pushing its use as PM tracking, but its too complicated. I can't get people to sit and train. So this software has to be easy.

• Should programming languages be strict or loose?

  - by Ralph

  In Python and JavaScript, semi-colons are optional. In PHP, quotes around array-keys are optional ($_GET[key] vs $_GET['key']), although if you omit them it will first look for a constant by that name. It also allows 2 different styles for blocks (colon, or brace delimited). I'm creating a programming language now, and I'm trying to decide how strict I should make it. There are a lot of cases where extra characters aren't really necessary and can be unambiguously interpreted due to priorities, but I'm wondering if I should still enforce them or not to encourage good programming habits. What do you think?

• How does one pluralize <see cref="Notation">'s?

  - by Jordan

  What is the most appropriate way of writing this comment: /// <summary> /// Order - Identifies the ordinal location of this category /// relative to other listed categories. /// </summary> if I'm wanting to wrap "category" in <see> tags? I've considered: /// <summary> /// Order - Identifies the ordinal location of this <see cref="Category"/> /// relative to other listed <see cref="Category"/>'s. /// </summary> Do you see my dilemma? Edit: I should add that I am using Visual Studio's XML Comments. So I am somewhat restricted as to the schema. I believe cref has to point to a valid type reference.

• New vs Clone Git in Eclipse with EGit

  - by Matty F

  I'm not sure I have either my new repo or clone repo workflow, or both, setup correctly. When I create a new project I create a repo on github, can't clone from it as it's empty so I create a new project which goes into my workspace and then the git init runs on the workspace copy. So I end up with everything in workspace\project-name. However, when I clone from github first I need to clone the repo and this goes into my default git directory (C:\git) as git\cloned-project-name, I then need to import this Git repo as a project into my workspace and I end up with workspace\cloned-project-name effectively duplicating the project folder in the git area. I've tried to clone to workspace\cloned-project-name but then it asks to import the git project and if I try to use workspace\cloned-project-name again, it errs. What am I doing wrong? Thanks, Matt.

• Do you think code is self documenting?

  - by Desolate Planet

  This is a question that was put to me many years ago as a gradute in a job interview and it's kind of picked at my brain now and again and I've never really found a good answer that satisfies me. The interviewer in question was looking for a black and white answer, there was no middle ground. I never got the chance to ask about the rationale behind the question, but I'm curious why that question would be put to a developer and what you would learn from a yes or no answer? From my own point of view, I can read Java, Python, Delphi etc, but if my manager comes up to me and asks me how far along in a project I am and I say "The code is 80% complete" (and before you start shooting me down, I've heard this uttered in a couple of offices by developers), how exactly is that self documenting? Apologies if this question seems strange, but I'd rather ask and get some opinions on it to gain a better understanding of why it would be put to someone in an interview.

• How should I evaluate new browser languages?

  - by Andrea

  In these days there are many projects whose aim is to bring new languages to the browser by compiling them to JavaScript. Among the others one can mention ClojureScript, CoffeScript, Dart, haXe, Emscripten, Amber Smalltalk. I'd like to try a few of these out, but I am not sure what I should be looking for when evaluating these languages to see if they are suitable for production. How should I evaluate a new browser language, and what are the pitfalls I should be looking for?

• How do I handle priority and propagation in an event system?

  - by Peeter

  Lets say I have a simple event system with the following syntax: object = new Object(); object.bind("my_trigger", function() { print "hello"; }); object.bind("my_trigger", function() { print "hello2"; }); object.trigger("my_trigger"); How could I make sure hello2 is printed out first (I do not want my code to depend on which order the events are binded). Ontop of that, how would I prevent my events from propagating (e.g. I want to stop every other event from being executed)

• What tools are available for remote communication when working from home or with a distributed team?

  - by Ryan Hayes

  My supervisor is allowing my team to dip our toes in the water of working from home. Considering a recent aquisition of another company is requiring some employees to love this new idea which will hack up to an hour off their commute into work every morning, I really want this to succeed. In order to make it a success, we need good tools to make our lives a lot easier. We currently are set up with OpenVPN, and Team Foundation Server 2010 with SharePoint 2010, and use Live Messenger (for SharePoint integration and easier remote desktop) for IM. These are just what we use (and they are currently working well) , but you can suggest other products. So, what are some great tools that will helps us collaborate, communicate, and generally work together when we're hours apart?

• Validating data to nest if or not within try and catch

  - by Skippy

  I am validating data, in this case I want one of three ints. I am asking this question, as it is the fundamental principle I'm interested in. This is a basic example, but I am developing best practices now, so when things become more complicated later, I am better equipped to manage them. Is it preferable to have the try and catch followed by the condition: public static int getProcType() { try { procType = getIntInput("Enter procedure type -\n" + " 1 for Exploratory,\n" + " 2 for Reconstructive, \n" + "3 for Follow up: \n"); } catch (NumberFormatException ex) { System.out.println("Error! Enter a valid option!"); getProcType(); } if (procType == 1 || procType == 2 || procType == 3) { hrlyRate = hrlyRate(procType); procedure = procedure(procType); } else { System.out.println("Error! Enter a valid option!"); getProcType(); } return procType; } Or is it better to put the if within the try and catch? public static int getProcType() { try { procType = getIntInput("Enter procedure type -\n" + " 1 for Exploratory,\n" + " 2 for Reconstructive, \n" + "3 for Follow up: \n"); if (procType == 1 || procType == 2 || procType == 3) { hrlyRate = hrlyRate(procType); procedure = procedure(procType); } else { System.out.println("Error! Enter a valid option!"); getProcType(); } } catch (NumberFormatException ex) { System.out.println("Error! Enter a valid option!"); getProcType(); } return procType; } I am thinking the if within the try, may be quicker, but also may be clumsy. Which would be better, as my programming becomes more advanced?

• Automatic Appointment Conflict Resolution

  - by Thomas

  I'm trying to figure out an algorithm for resolving appointment times. I currently have a naive algorithm that pushes down conflicting appointments repeatedly, until there are no more appointments. # The appointment list is always sorted on start time appointment_list = [ <Appointment: 10:00 -> 12:00>, <Appointment: 11:00 -> 12:30>, <Appointment: 13:00 -> 14:00>, <Appointment: 13:30 -> 14:30>, ] Constraints are that appointments: cannot be after 15:00 cannot be before 9:00 This is the naive algorithm for i, app in enumerate(appointment_list): for possible_conflict in appointment_list[i+1:]: if possible_conflict.start < app.end: difference = app.end - possible_conflict.start possible_conflict.end += difference possible_conflict.start += difference else: break This results in the following resolution, which obviously breaks those constraints, and the last appointment will have to be pushed to the following day. appointment_list = [ <Appointment: 10:00 -> 12:00>, <Appointment: 12:00 -> 13:30>, <Appointment: 13:30 -> 14:30>, <Appointment: 14:30 -> 15:30>, ] Obviously this is sub-optimal, It performs 3 appointment moves when the confict could have been resolved with one: if we were able to push the first appointment backwards, we could avoid moving all the subsequent appointments down. I'm thinking that there should be a sort of edit-distance approach that would calculate the least number of appointments that should be moved in order to resolve the scheduling conflict, but I can't get the a handle on the methodology. Should it be breadth-first or depth first solution search. When do I know if the solution is "good enough"?

• Forking project on Github process

  - by Mike Wills

  There is a project on Github that I mostly like and want to use. There are a few things I want to do differently/remove that doesn't make sense for what I want/need. Also I want to add a few things as well. As I understand it, I should fork the project and I can make whatever changes I want and push back to my fork. From there, I also want to occasionally pull into my fork the changes from the original project so I get the latest bug fixes/features. Am I off-base of how I think it should work? How would bring in the changes from the original project?

• How does this ruby error handling module code work

  - by Michael Durrant

  Trying to get a better handle on ruby exception handling. I have this code (from a book): def err_with_msg(pattern) m = Module.new (class << m; self; end).instance_eval do define_method(:===) do |e| pattern === e.msg end end m end So ok this is a method. We're creating a new Module. I think of module as mix-ins. Not sure what it's doing here. Not we add the module to the class. Fair enough. Then we have self on its own. What that for? I guess we have a little anonymouse method this is just about self. hmmm ok, now for each of the above, check the pattern match. but for each, I thought the above for for a new Module, did the module get to use instance's by being included? A better explanation of what's going on here would be most helpful.

• From TFS to Git

  - by Saeed Neamati

  I'm a .NET developer and I've used TFS (team foundation server) as my source control software many times. Good features of TFS are: Good integration with Visual Studio (so I do almost everything visually; no console commands) Easy check-out, check-in process Easy merging and conflict resolution Easy automated builds Branching Now, I want to use Git as the backbone, repository, and source control of my open source projects. My projects are in C#, JavaScript, or PHP language with MySQL, or SQL Server databases as the storage mechanism. I just used github.com's help for this purpose and I created a profile there, and downloaded a GUI for Git. Up to this part was so easy. But I'm almost stuck at going along any further. I just want to do some simple (really simple) operations, including: Creating a project on Git and mapping it to a folder on my laptop Checking out/checking in files and folders Resolving conflicts That's all I need to do now. But it seems that the GUI is not that user friendly. I expect the GUI to have a Connect To... or something like that, and then I expect a list of projects to be shown, and when I choose one, I expect to see the list of files and folders of that project, just like exploring your TFS project in Visual Studio. Then I want to be able to right click a file and select check-in... or check-out and stuff like that. Do I expect much? What should I do to easily use Git just like TFS? What am I missing here?

• Changes in Language Punctuation [closed]

  - by Wes Miller

  More social curiosity than actual programming question... (I got shot for posting this on Stack Overflow. They sent me here. At least i hope here is where they meant.) Based on the few responses I got before the content police ran me off Stack Overflow, I should note that I am legally blind and neatness and consistency in programming are my best friends. A thousand years ago when I took my first programming class (Fortran 66) and a mere 500 years ago when I tokk my first C and C++ classes, there were some pretty standard punctuation practices across languages. I saw them in Basic (shudder), PL/1, PL/AS, Rexx even Pascal. Ok, APL2 is not part of this discussion. Each language has its own peculiar punctuation. Pascal's periods, Fortran's comma separated do loops, almost everybody else's semicolons. As I learned it, each language also has KEYWORDS (if, for, do, while, until, etc.) which are set off by whitespace (or the left margin) if, etc. Each language has function, subroutines of whatever they're called. Some built-in some user coded. They were set off by function_name( parameters );. As in sqrt( x ) or rand( y ); Lately, there seems to be a new set of punctuation rules. Especially in c++ where initializers get glued onto the end of variable declarations int x(0); or auto_ptr p(new gizmo); This usually, briefly fools me into thinking someone is declaring a function prototype or using a function as a integer. Then "if" and 'for' seems to have grown parens; if(true) for(;;), etc. Since when did keywords become functions. I realize some people think they ARE functions with iterators as parameters. But if "for" is a function, where did the arg separating commas go? And finally, functions seem to have shed their parens; sqrt (2) select (...) I know, I koow, loosening whitespace rules is good. Keep reading. Question: when did the old ways disappear and this new way come into vogue? Does anyone besides me find it irritating to read and that the information that the placement of punctuation used to convey is gone? I know full well that K&R put the { at the end of the "if" or "for" to save a byte here and there. Can't use that excuse here. Space as an excuse for loss of readability died as HDD space soared past 100 MiB. Your thoughts are solicited. If there is a good reason to do this, I'll gladly learn it and maybe in another 50 years I'll get used to it. Of course it's good that compilers recognize these (IMHO) typos and keep right on going, but just because you CAN code it that way doesn't mean you HAVE to, right?

• Statistical Software Quality Control References

  - by Xodarap

  I'm looking for references about hypothesis testing in software management. For example, we might wonder whether "crunch time" leads to an increase in defect rate - this is a surprisingly difficult thing to do. There are many questions on how to measure quality - this isn't what I'm asking. And there are books like Kan which discuss various quality metrics and their utilities. I'm not asking this either. I want to know how one applies these metrics to make decisions. E.g. suppose we decide to go with critical errors / KLOC. One of the problems we'll have to deal with with that this is not a normally distributed data set (almost all patches have zero critical errors). And further, it's not clear that we really want to examine the difference in means. So what should our alternative hypothesis be? (Note: Based on previous questions, my guess is that I'll get a lot of answers telling me that this is a bad idea. That's fine, but I'd request that it's based on published data, instead of your own experience.)
