• 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 can I approach creating an efficient algorithm for maximizing value with these specific constraints?

  - by sway

  I'm having trouble coming up with an approach that isn't n^2 for this problem. Here's a contrived, simplified version I've come up with: Let's say you're a company that needs 4 employees to launch in a new city, a manager, two salespeople, and a customer support rep, and you magically know how much impact every candidate will have and how much salary they require to take the job. Your table of potential employees looks something like this: Name Position Salary Impact Adam Smith Manager 60,000 11 Allison Brown Salesperson 40,000 9 Brad Stewart Manager 55,000 9 ...etc (thousands of records) What algorithmic approach can be taken to find the maximum "impact" while still filling all the positions and remaining under, say, a 200,000 budget? Thanks!

• Current iOS version/device statistics?

  - by hotpaw2

  The answer to this SO question has become stale: iOS version/device statistics - where can i find? because time currency wasn't part of that question, and iOS version updates have been release since this question was asked. Is there a web site or other publicly available source which keeps a current or frequently updated list of the percentages of iOS devices and OS versions in use, perhaps by continual monitoring of app analytics or web site logs or other means? And what device or OS information are iOS app analytics currently allowed to report, if any? (...assuming an appropriate privacy policy and adhering to such, of course.)

• How should I host our scalable worker processes?

  - by Pieter Breed

  We are designing a new architecture for an enterprise business. The principles we've followed so far is not to develop what you can (possible buy and) deploy, ie, don't reinvent any wheels. In this way we've decided on CQRS, RabbitMQ, Riak and a bunch of other things. We still need to write /some/ business code though and these will be in the form of worker processes, which will consume commands from a message queue and after any side-effects, produce events onto another message queue. The idea behind this is that via the competing-consumers design we will have a scalable design right out of the box. One option is of writing a management infrastructure that will know how to: deploy code instantiate processes kill processes update configuration etc IE provide fault tolerance and scalability. Also, this is exactly what something like GAE and Heroku does for you, but in a public setting and in our organization, public is bad. My question is, is there an out-of-the-box solution that we can use to host our consumers in? Like a private cloud or private platform-as-a-service. Private Heroku or GAE. Is there some kind of software or software product with which we can do all of these things and thereby get scalability and fault tolerance over our consumers?

• 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 should you say in post-interview?

  - by ??? Shengyuan Lu

  When you are leaving your company, you will be post-interviewed. As best practice, you shouldn't say something bad about your company, because it will "burn your bridge", another best practice is to keep silence if the company really sucks. I think if you decide to leave, there must be a reason(s) making you really unhappy, and I am sure you will have something really important to tell your employer. Then what is your attitude about post-interview?

• What are the standard practices for database access in .net?

  - by Gulshan

  I have seen weird database access practices in .net. I have seen stored procedures for every database tasks. I have seen every database property name is preceded by it's table name. I have seen fully separate layer/.dll for very few or no business logic. I have seen along with ORMs, there are separate data access layer playing the same role. And with them, I have always heard- "These are the standards you have to maintain". So, what are the real standards for data access in .net? What are the rules you follow?

• Learning Zend Framework 1 or 2?

  - by ehijon

  I have programmed for a few years in php and now I'm going to learn zend framwork. Zend is very popular and there are a lot of tutorials, books and documentation out there. But I saw in the last months that there is a second version of Zend, but it's not so used and popular, not yet. I think it is better to start with a new version, but I don't know what to do now, as when I see job offers many people require the first version. Which version do you suggest me?

• Avoiding the Anaemic Domain - How to decide what single responsibility a class has

  - by thecapsaicinkid

  Even after reading a bunch I'm still falling into the same trap. I have a class, usually an enity. I need to implement more than one, similar operations on this type. It feels wrong to (seemingly arbitrarily) choose one of these operations to belong inside the entity and push the others out to a separate class; I end up pushing all operations to service classes and am left with an anaemic domain. As a crude example, imagine the typical Employee class with numeric properties to hold how many paid days the employee is entitled to for both sickness and holiday and a collection of days taken for each. public class Employee { public int PaidHolidayAllowance { get; set; } public int PaidSicknessAllowance { get; set; } public IEnumerable<Holiday> Holidays { get; set; } public IEnumerable<SickDays> SickDays { get; set; } } I want two operations, one to calculate remaining holiday, another for remaining paid sick days. It seems strange to include say, CalculateRemaingHoliday() in the Employee class and bump CalculateRemainingPaidSick() to some PaidSicknessCalculator class. I would end up with a PaidSicknessCalculator and a RemainingHolidayCalculator and the anaemic Employee entity as seen above. The other alternative would be to put both operations in the Employee class and kick Single Responsibility to the curb. That doesn't make for particularly maintainable code. I suppose the Employee class should have some initialisation/validation logic (not accepting negative alowances etc.) So maybe I just stick to basic initialisation and validation in the entities themselves and be happy with my separate calculator classes. Or maybe I should be asking myself if Anaemic Domain is actually causing me some tangible problems with my code.

• I need help with algorithms, how do I improve?

  - by David Burr

  I usually do well at figuring out solutions to programming assignments but for some reason, I'm really struggling in my Algorithms class. I'm not failing but I know I can do better. When I'm confronted with problems like "Divide the array to 2 subarrays so that the sum of each subarray is equal to the other subarray," I feel like my brain won't cooperate and think and I end up not being able to solve it. Some of the things I'm doing right now to help myself: reading CLR (1st ed.) -- it takes a lot of time for stuff to sink in and I can't understand most of it solving some problems -- no matter how much I try, most of the time, I end up googling for the solution before I understand how to solve it I know that good algorithmic skills are very important because lots of good companies ask these sorts of questions in their interview process so I'm a bit worried right now. What else can can I do to improve my algorithmic/problem solving skills? Any advice on how to deal with this?

• 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?

• Best practice with pyGTK and Builder XML files

  - by Phoenix87

  I usually design GUI with Glade, thus producing a series of Builder XML files (one such file for each application window). Now my idea is to define a class, e.g. MainWindow, that inherits from gtk.Window and that implements all the signal handlers for the application main window. The problem is that when I retrieve the main window from the containing XML file, it is returned as a gtk.Window instance. The solution I have adopted so far is the following: I have defined a class "Window" in the following way class Window(): def __init__(self, win_name): builder = gtk.Builder() self.builder = builder builder.add_from_file("%s.glade" % win_name) self.window = builder.get_object(win_name) builder.connect_signals(self) def run(self): return self.window.run() def show_all(self): return self.window.show_all() def destroy(self): return self.window.destroy() def child(self, name): return self.builder.get_object(name) In the actual application code I have then defined a new class, say MainWindow, that inherits frow Window, and that looks like class Main(Window): def __init__(self): Window.__init__(self, "main") ### Signal handlers ##################################################### def on_mnu_file_quit_activated(self, widget, data = None): ... The string "main" refers to the main window, called "main", which resides into the XML Builder file "main.glade" (this is a sort of convention I decided to adopt). So the question is: how can I inherit from gtk.Window directly, by defining, say, the class Foo(gtk.Window), and recast the return value of builder.get_object(win_name) to Foo?

• OOP oriented PHP app source code samples and advice

  - by abel

  The day I have been dreading has arrived. I never felt OOP or good software design was important(I knew they were important, but I thought I could manage without them.). However having read otherwise almost everywhere on the interwebs, I started dreading the day when my client would ask me for new features in an existing app. The day has come and the pain is unbearable! I have never coded my PHP websites "properly"(PHP is my primary language and the bulk of my work. I am learning Python (using web2py)) I take care that the website doesn't fall apart in a daily use scenario. I code pages like I was creating a list of static html files with bits of "magic code" in each of them(this bugs me a lot). How do I make the whole app more or less a single object? For eg. How do I design the object model for an invoicing app? I use a lot of functions for doing any particular thing in the same fashion throughout the app(for eg. validation, generating ids, calculating taxes etc.). I know the basics of OOP in general. Can anyone point me to source code samples of functional apps written in php? Or can someone provide pointers so I can recode my existing apps in a more modular way.

• 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.

• Spring can commit Transaction in finally block with RunTimeException in try block [migrated]

  - by Chance Lai

  The project used Spring + Hibernate Sample code: public void method(){ try{ dao.saveA(entityA); throw RuntimeException; dao.saveB(entityB); }catch(RuntimeException e){ throw e; }finally{ dao.saveC(entityC) } } Finally, just entityC will be saved in database in test. I think saveA, saveB, saveC in the same transaction,they should not be committed. In this case, I want to know why entityC is committed. How does Spring do this in the finally block?

• How do you learn a new programming language?

  - by Naveen

  I am C++ developer with some good experience on it. When I try to learn a new language ( have tried Java, C#, python, perl till now) I usually pickup a book and try to read it. But the problem with this is that these books typically start with some very basic programming concepts such as loops, operators etc and it starts to get very boring soon. Also, I feel I would get only theoeritcal knowledge without any practical knowledge on writing the code. So my question is how do you tacke these situations? do you just skip the chapters if its explaining something basic? also, do you have some standard set of programs that you will try to write in every new programming language you try to learn?

• Didatic approaches to teach versioning with Git

  - by Herberth Amaral

  I have already taught versioning with Git, but I think it could be more enjoyable for the guys I teach if I use another approach to teach them. The guys I mentioned before were used to working with SVN and I tried to teach Git based on SVN. Not such a good idea. It seems that some guys/teams which use SVN need a re-education on version control when they're learning Git or another DCVCS. In another attempt, I tried to show a scenario where a development team try to work without a (D)VCS and then I showed how their lives could be easier if they used a (D)VCS. I had the impression that part of the audience left the presentation without a clue what I was talking about. I've taught other classes on other subjects without problems, so I think this is not a issue with me as a teacher, but with my method. I know Git and versioning as well I know the other subjects I've presented to the other classes. So, basically, how to teach Git/DCVCS? Start with some diffs/patches and manual versioning and then teach how it can be more productive with Git? Start with Git object model? Or try to start with some pretty commands and try to save some time? To be clear: I'm looking for approaches on how to teach DCVCS (focusing on Git) effectively, based on real experiences.

• deep expertise in one technology or not so deep understanding of many technologies

  - by district

  Hello everyone. I started to feel a little bit confused recently about my career path as software developer, about what I do, what I know and do I need it. I am 21 years now and I have 3 years of experience. I've been dealing with java/C++ projects, Servlet/JSP/JSF, desktop QT, also some mobile development (Symbian, Android) I work for a quite a small company, around 20 developers with different projects. I'm also a student. The problem is that I'm not sure if I'm taking the right road here. I'm starting to work with new technology every few months. I don't have deep understanding in any of these and I'm not sure if this is what I need. I will probably not become an expert in any of these. The other path is maybe to start working for a big company which use one set of technologies and become an expert. What's your opinion on this topic ? What is more valuable ?

• Vernon's book Implementing DDD and modeling of underlying concepts

  - by EdvRusj

  Following questions all refer to examples presented in Implementing DDD In article we can see from Figure 6 that both BankingAccount and PayeeAccount represent the same underlying concept of Banking Account BA 1. On page 64 author gives an example of a publishing organization, where the life-cycle of a book goes through several stages ( proposing a book, editorial process, translation of the book ... ) and at each of those stages this book has a different definition. Each stage of the book is defined in a different Bounded Context, but do all these different definitions still represent the same underlying concept of a Book, just like both BankingAccount and PayeeAccount represent the same underlying concept of a BA? 2. a) I understand why User shouldn't exist in Collaboration Context ( CC ), but instead should be defined within Identity and Access Context IAC ( page 65 ). But still, do User ( IAC ), Moderator ( CC ), Author ( CC ),Owner ( CC ) and Participant ( CC ) all represent different aspects of the same underlying concept? b) If yes, then this means that CC contains several model elements ( Moderator, Author, Owner and Participant ), each representing different aspect of the same underlying concept ( just like both BankingAccount and PayeeAccount represent the same underlying concept of a BA ). But isn't this considered a duplication of concepts ( Evan's book, page 339 ), since several model elements in CC represent the same underlying concept? c) If Moderator, Author ... don't represent the same underlying concept, then what underlying concept does each represent? 3. In an e-commerce system, the term Customer has multiple meanings ( page 49 ): When user is browsing the Catalog, Customer has different meaning than when user is placing an Order. But do these two different definitions of a Customer represent the same underlying concept, just like both BankingAccount and PayeeAccount represent the same underlying concept of a BA? thanks

• Does something like this "dream" online IDE product exist?

  - by Dan Tao

  I was thinking the other day, it would be amazing if a web-based product with the following features existed: Customizable text editor with nice formatting like ACE Real-time collaborative editing like Google Docs (or the late Wave) Online multi-language compiling capabilities like Ideone.com SCM hosting and/or integration + issue management like... oh, I don't know, GitHub Clearly (considering the examples), all the desired features exist. Is there anywhere that they exist all in one product? If not, does anything come close?

• What are the benefits of PHP?

• Fair 2-combinations

  - by Tometzky

  I need to fairly assign 2 experts from x experts (x is rather small - less than 50) for every n applications, so that: each expert has the same number of applications (+-1); each pair of experts (2-combination of x) has the same number of applications (+-1); It is simple to generate all 2-combinations: for (i=0; i<n; i++) { for (j=i+1; j<n; j++) { combinations.append(tuple(i,j)); } } But to assign experts fairly I need to assign a combination to an application i correct order, for example: experts: 0 1 2 3 4 fair combinations: counts 01234 01 11000 23 11110 04 21111 12 22211 34 22222 02 32322 13 33332 14 34333 03 44343 24 44444 I'm unable to come up with a good algorithm for this (the best I came up with is rather complicated and with O(x4) complexity). Could you help me?
