• Recommended language and IDE for simple linux application [on hold]

  - by niklon

  I want to write a simple program on Debian with Gnome. Application will act as a side bar, giving simple information on online servers statuses. I preferably have a black transparent background(Terminal-like). I'm asking this question because I was previously writing programs in .NET C# for myself, and now I don't want to get to Mono, but something more conventional. What language should I choose for this task? What would be the recommended way to do it?(eg. what IDE)

• Materialized View vs POJO View based on Objects representing Oracle tables

  - by Zack Macomber

  I have about 12 Oracle tables that represent data that's being integrated from an external system into my web application. This data is going to be used in an informational and comparative manner for the clients using my web application. On one particular page of my web application, I need to combine data from 3 - 5 Oracle tables for display as an HTML table on the page. We are NOT currently using a framework (Apache Struts for instance) and we're not in a position to move this Java web application into one at this moment (I'm trying to get us there...). I am certainly not an architect, but I see one of two ways that I can effectively build this page (I know there are other ways, but these seem like they would be good ones...): 1. Create an Oracle Materialized View that represents what the HTML table should look like and then create a POJO based on the View that I can then integrate into my JSP. 2. Create POJOs that represent the Oracle tables themselves and then create another POJO that is the View used for the HTML table and then integrate that POJO into my JSP. To me, it seems the Materialized View would possibly offer quicker results which is always what we strive for in web applications. But, if I just create 12 POJOs that represent the Oracle tables and then build POJO Views off of those, I have the advantage of keeping all the code in one place for this and possibility for creating any number of different views and reusable components in my web application. Any thoughts on which one might be the better route? Or, maybe you know of an even better one?

• Why would I want to install node.js in my Rails Application?

  - by Crazy JIm

  Okay guys, I'm super confused. I thought node.js was a sever side framwork, basically the js version of Ruby's Rails or PHP's Zend. However, I'm having some difficulty with turbolinks, and it seems to be the way to fix it is through installing node.js I mean, I don't understand this at all. How can two frameworks work together like this? Also, it's not a gem (that REALLY would have confused me), you have to install node.js it onto your local machine by running (in the case of Ubuntu) sudo apt-get install nodejs Firstly, how does this totally separate framwork have any bearing on rails? Secondly, surely this isn't fixing the problem forever? When you specify a gem in your gemfile, the server knows what external libraries to install. How does the server know to install nodejs?

• Java - What methods to put in an interface and what to keep out

  - by lewicki

  I'm designing a file handler interface: public interface FileHandler { public void openFileHandler(String fileName); public void closeFileHandler(); public String readLine(); public String [] parseLine(String line); public String [] checkLine(String line[]); public void incrementLineCount(); public void incrementLineSuccessCount(); public void incrementLineErrorCount(); public int getLineCount(); public int getLineSuccessCount(); public int getLineErrorCount(); } It is soon apparent to me that these methods can't be made private. I don't want incrementLineCount to be public. What is proper way to design an interface like this?

• Is Java easy decompilation a factor worth considering

  - by Sandra G

  We are considering the programming language for a desktop application with extended GUI use (tables, windows) and heavy database use. We considered Java for use however the fact that it can be decompiled back very easily into source code is holding us back. There are of course many obfuscators available however they are just that: obfuscators. The only obfuscation worth doing we got was stripping function and variables names into meaningless letters and numbers so that at least stealing code and renaming it back into something meaningful is too much work and we are 100% sure it is not reversible back in any automated way. However as it concerns to protecting internals (like password hashes or sensible variables content) we found obfuscators really lacking. Is there any way to make Java applications as hard to decode as .exe counterparts? And is it a factor to consider when deciding whether to develop in Java a desktop application?

• I need recommendations on free, open source, PHP-based business intelligence widget frameworks [on hold]

  - by Volomike

  I'm a PHP developer on Linux, and my manager wants a business intelligence dashboard. He wants to see in real-time our profit/loss stuff in fancy charts, based on our software sales. I could code it all from scratch and use Google Charts API or some other charts API to help me. However, I wanted to know if there was a free, open source, PHP-based business intelligence package out there, or some sort of widget framework that I could start with. That way, I can build the BI widgets inside that framework and not have to do everything from scratch. I apologize ahead of time if this is the wrong stackexchange where to place this query. I don't know where to place this query, and do want to follow the rules.

• Which Programming Languages Support the Following Features?

  - by donalbain

  My personal programming background is mainly in Java, with a little bit of Ruby, a tiny bit of Scheme, and most recently, due to some iOS development, Objective-C. In my move from Java to Objective-C I've really come to love some features that Objective-C has that Java doesn't. These include support for both static and dynamic typing, functional programming, and closures, which I'm trying to leverage in my code more often. Unfortunately there are trade-offs, including lack of support for generics and (on iOS at least) no garbage collection. These contrasts have lead me to start a search for some of the programming languages that support the following features: Object Oriented Functional Programming Support Closures Generics Support for both Static and Dynamic Typing Module Management to avoid classpath/dll hell Garbage Collection Available Decent IDE Support Admittedly some of these features(IDE support, Module Management) may not be specific to the language itself, but obviously influence the ease of development in the language. Which languages fit these criteria?

• Is ORM an Anti-Pattern?

  - by derphil

  I had a very stimulating and interessting discussion with a colleague about ORM and it's Pros and Cons. In my opinion, an ORM is useful only in the rarest cases. At least in my experience. But I don't want to list my own arguments at this time. So I ask you, what do you think about ORM? What are the Pros and the Cons? P.S. I've posted this "question" yesterday on Stackoverflow, but some of the user think, that this should better posted here.

• Deferred Open Source licensing

  - by Thomas W.

  Are there established models for releasing an initially proprietary piece of software under FLOSS conditions after a defined period or a certain point of time? The main problem here is that all parties involved must be able to trust that the Open Source licensing will actually take place at the defined time and no party can further defer or cancel this process. Clearly such a model has its problems, for example it's problematic to deal with contributions from "outside", legally and technically. Ghostscript is a prominent example where a deferred model has been used and abandoned. However, if certain parties involved will insist on keeping the software proprietary, at least for a certain period of time, then the only options are a deferred Open Source licensing model or no Open Source licensing at all. I think I read about services that serve as trusted parties who take care of Open Sourcing the software. However, I was not successful in spotting any of those.

• Does this BSD-like license achieve what I want it to?

  - by Joseph Szymborski

  I was wondering if this license is: self defeating just a clone of an existing, better established license practical any more "corporate-friendly" than the GPL too vague/open ended and finally, if there is a better license that achieves a similar effect? I wanted a license that would (in simple terms) be as flexible/simple as the "Simplified BSD" license (which is essentially the MIT license) allow anyone to make modifications as long as I'm attributed require that I get a notification that such a derived work exists require that I have access to the source code and be given license to use the code not oblige the author of the derivative work to have to release the source code to the general public not oblige the author of the derivative work to license the derivative work under a specific license Here is the proposed license, which is just the simplified BSD with a couple of additional clauses (all of which are bolded).

• Best practice in setting return value (use else or?)

  - by Deckard

  Whenever you want to return a value from a method, but whatever you return depends on some other value, you typically use branching: int calculateSomething() { if (a == b) { return x; } else { return y; } } Another way to write this is: int calculateSomething() { if (a == b) { return x; } return y; } Is there any reason to avoid one or the other? Both allow adding "else if"-clauses without problems. Both typically generate compiler errors if you add anything at the bottom. Note: I couldn't find any duplicates, although multiple questions exist about whether the accompanying curly braces should be on their own line. So let's not get into that.

• 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?

• Design: classes with same implementation but different method names

  - by Dror Helper

  I have multiple classes that have similar implementation for different named methods: class MyClassX { public int MyClassXIntMethod(){} public string MyClassXStringMethod(){} } class MyClassY { public int MyClassYIntMethod(){} public string MyClassYStringMethod(){} } the methods inside the classes have similar implementation but because the method's names are different (due to 3rd party constraints) i cannot use inheritance. I'm looking for an elegant solution that would be better than implementing the same functionality over and over again.

• 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.

• Cloud service and IM protocol advice, for a backend to group chat mobile app

  - by Jonathan

  Overview I’m going to develop an app on Android and iOS. It will allow users to set up group ‘chat rooms’ and talk on chat rooms set up by other users. The service needs to be highly scalable, such that it could accommodate a massive increase in users overnight (we can only dream). Chat requirements The chat protocol used should be flexible: it should allow me to determine who can view/post on ‘chat rooms’ based on certain other factors, as determined by the first poster/creator of the particular ‘chat room’. It should also allow for users to simply install the app and begin using the service, after only providing a simple nickname (which could be changed later). Chat protocol plans Having looked around I think the XMPP protocol is the best candidate. In particular the Multi-user chat extension looks like what I’ll need. Would this be most suited to my requirements, or do you know another potential solution? Cloud service I have been deciding between Amazon Web Services, Google App Engine and Windows Azure. I’m coming to the conclusion that Azure will be best, as it is easier to manage than AWS (ease of scalability will be a key factor in the design), I think it may be less restricted than GAE, plus Azure will soon have toolkits to allow easy interfacing with both Android and iOS phones. Is this the decision you would have made, or would you recommend/look into other cloud services? General project philosophy I have only recently started looking into this project’s feasibility, and am no expert on any of its aspects. So wherever possible I will leave the actual implementations to experts, i.e. choosing a higher-level cloud service, using a well-documented plugin of a, proven reliable, group chat protocol etc. My background I have some programming knowledge from a computer science degree. Main languages I’ve used have been Java and Python, but I don’t want this to affect design decisions for the project. The most appropriate languages for the task should be used, i.e. I don’t mind learning a lot of new skills (my current programming levels are relatively basic anyway). Thank you Thanks for reading, and any advice you have about any aspect would be greatly appreciated :-)

• How long was Microsoft working on .NET before they released it?

  - by Richard DesLonde

  With the whole CLI, CTS, CLS, etc., not only did they release a powerful platform/infrastructure, but they released all the specs that describe it etc. It supports potentially infinite myriad languages, platforms, etc. This seems like an insane amount of work, even for a behemoth like Microsoft - especially since it turns out they did a damn good job. How long were they working on this before releasing it (.NET 1.0)?

• When creating an library published on CodePlex, how "bad" would it be for the unit-test projects to rely on commercial products?

  - by Lasse V. Karlsen

  I have started a project on CodePlex for a WebDAV server implementation for .NET, so that I can host a WebDAV server in my own programs. This is both a learning/research project (WebDAV + server portion) as well as a project I think I can have much fun with, both in terms of making it and using it. However, I see a need to do mocking of types here in order to unit-testing properly. For instance, I will be relying on HttpListener for the web server portion of the WebDAV server, and since this type has no interface, and is sealed, I cannot easily make mocks or stubs out of it. Unless I use something like TypeMock. So if I used TypeMock in the unit-test projects on this library, how bad would this be for potential users? The projects are made in C# 3.5 for .NET 3.5 and 4.0, and the project files was created with Visual Studio 2010 Professional. The actual class libraries you would end up referencing in your software would of course not be encumbered with anything remotely like this, only the unit-test libraries. What's your thoughts on this? As an example, I have in my old code-base, which is private, the ability to just initiate a WebDAV server with just this: var server = new WebDAVServer(); This constructs, and owns, a HttpListener instance internally, and I would like to verify through unit-tests that if I dispose of this server object, the internal listener is disposed of. If, on the other hand, I use the overload where I hand it a listener object, this object should not be disposed of. Short of exposing the internal listener object to the outside world, something I'm a bit loath to do, how can I in a good way ensure that the object was disposed of? With TypeMock I can mock away parts of this object even though it isn't accessed through interfaces. The alternative would be for me to wrap everything in wrapper classes, where I have complete control.

• 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?

• Efficient coding in Visual Studio (or another IDE), with touch typing

  - by cheeesus

  Moving the cursor to another position in code is one of the most frequent actions when coding. I don't write my programs from the beginning to the end, like a letter. However, moving the cursor requires me to move my right hand to the key arrows or to the mouse, which feels like an interruption to my writing rhythm, since I'm using touch typing. I want my hands to rest on the keyboard. It's difficult to explain what I mean, but I think every coder using touch typing knows what I mean. I tried many things, like defining some shortcuts as surrogate arrow keys (Shift+Alt+J, K, L, I), or buying a keyboard with a Trackpoint, Trackpad, or Trackball on it, but I have not yet found a satisfying solution to the problem. What is the best solution you know of, regardless of which IDE you use? Edit: Thank you for your answers. I am using a lot of shortkeys, but I think using a Vim plugin in Visual Studio would interfere too much with the shortkeys I am used to. Also, I have a keyboard with a built-in mouse, but I'm still looking for a better solution.

• session management: verifying a user's log-in state

  - by good_computer

  I am storing sessions in my database. Everytime a user logs in, I create a new row corresponding to the new session, generate a new session id and send it as a cookie to the browser. My session data looks something like this: { 'user_id': 1234 'user_name': 'Sam' ... } When a request comes, I check whether a cookie with a session id is sent. If it is, I fetch session data from my database (or memcache) corresponding to that session id. When the user logs out, I remove the session data from my database (and memcache), and delete the cookie from the user's browser too. Notice that in my session data, I don't have something like logged_in: true. This is because if I find a session record in the database (or memcache) I deduce that the user is logged in, and if there is no session record found, the user is not logged in. My question is: is this the right approach? Should I have a logged_in key in my session data? Is there any possibility that a session record may be present on the server where the corresponding user is actually NOT logged in? Are there any security implications in having or not having such a key?

• Advice: How to convince my newly annointed team lead against writing the code base from scratch

  - by shan23

  I work in a pretty reknowned MNC, and the module that I work in has been assigned to a new "lead". The code base is pretty huge (~130K or more, with inter dependencies on other modules) , but stable - some parts have grown ugly over the years, but its provably in working state. (Our products are running for years on them, even new ones). The problem is, our lead wants to rewrite the code from scratch, to encompass "finer granularity and a proactive design". I know in my guts thats not a very good idea, but how do I convince him/the rest of the team(who are pretty much more senior than me in terms of years of exp), without sounding too pedantic myself (Thou shalt not rewrite , as Joel et al have clear articles prohibiting it)? I have a good working relation with the person concerned, and don't want to ruin it, but neither do I want to be party to a decision which would surely plague us for years to come !! Any suggestions for a milder,yet effective approach ? Even accounts of how you have tackled such a situation to your liking would help me a lot! EDIT: The code base I'm talking about is not a product/GUI, but at kernel level with all the critical functionalities for our product. I hope now you know why i sound so apprehensive !!

• Possible for one developer to work on a site thats on another developer's server?

  - by cire4

  Sorry for the confusing title. Let me explain: I am currently trying to get a site developed. My current developer has taken the site about as far as I think they are capable of and I am planning on hiring another developer to put the finishing touches on it, debug it and upgrade some of the more technical details. The site is hosted on my current developer's server. They are scheduled to work on it until mid-April, at which point they will transfer the site to my server. I would like the new developer to get started on the upgrades to the site as soon as possible. So my question is this: Is it possible for the new developer to start working on upgrades to the site while it is still on the old developer's server (and without the old developer knowing about it)? Would the new developer have to create a mirror site and work on it that way? I'm having trouble imagining if this is possible so any advice you can offer would be much appreciated!

• My first development job working at a company, what things to look out for?

  - by Kim Jong Woo

  So I've worked on my own all this time, selling software, creating a few web applications on my own. I had an Arts background I was self taught. It was a bit difficult to find a development position after endless trying, I finally landed a LAMP position. What I realized was it was all confidence issue. Before when I didn't know a few things I panicked but after spending such a long time working on my own projects and solving various problems, I felt confident enough that I could fulfill requirements on my own. I hope this helps other people applying for jobs This is the first time I will be developing with other team members in an office, are there anything I should prepare for my first day at work next week? Any tips and pointers while working as a developer at a company? I'm kinda nervous but excited.
