• Are trivial protected getters blatant overkill?

  - by Panzercrisis

  Something I really have not thought about before (AS3 syntax): private var m_obj:Object; protected function get obj():Object { return m_obj; } private var m_str:String; protected function get str():String { return m_str; } At least subclasses won't be able to set m_obj or m_str (though they could still modify m_obj). Is this just blatant overkill? I am not talking about doing this as opposed to making them public. I am talking about doing this instead of just making the variables themselves protected. Like this: protected var m_obj:Object; //more accessible than a private variable with a protected getter protected var m_str:String; //more accessible than a private variable with a protected getter

• Tips for achieving "continual" delivery

  - by Ben

  A team is experiencing difficulty releasing software on a frequent basis (once every week). What follows is a typical release timeline: During the iteration: Developers work on stories on the backlog on short-lived (this is enthusiastically enforced) feature branches based on the master branch. Developers frequently pull their feature branches into the integration branch, which is continually built and tested (as far as the test coverage goes) automatically. The testers have the ability to auto-deploy integration to a staging environment and this occurs multiple times per week, enabling continual running of their test suites. Every Monday: there is a release planning meeting to determine which stories are "known good" (based on the testers' work), and hence will be in the release. If there is a known issue with a story, the source branch is pulled out of integration. no new code (only bug fixes requested by the testers) may be pulled into integration on this Monday to ensure the testers have a stable codebase to cut a release from. Every Tuesday: The testers have tested the integration branch as much as they possibly can have given the time available and there are no known bugs so a release is cut and pushed out to the production nodes slowly. This sounds OK in practise, but we have found that it is incredibly difficult to achieve. The team sees the following symptoms "subtle" bugs are found on production that were not identified on the staging environment. last minute hot-fixes continue into the Tuesday. problems on the production environment require roll-backs which blocks continued development until a successful live deployment is achieved and the master branch can be updated (and hence branched from). I think test coverage, code quality, ability to regression test quickly, last minute changes and environmental differences are at play here. Can anyone offer any advice regarding how best to achieve "continual" delivery?

• Understanding Data Binding for Windows Phone 7

  - by nikhil

  I want to develop a simple app for the Windows Phone 7 platform. It's basically a vocabulary based game that involves the user moving word tiles from one area to another to score points. I want to know what is the best way of tying the UI to the game's backend? I saw the Windows Phone 7 jumpstart videos, there they touch up on Data Binding but don't really go into any depth. I'm a newbie and don't have any experience with designing the architecture for a phone app, It'd be great if someone could explain what steps I should be taking or guide me to a resource from where I could learn more.

• PHP - "tabulate" array - make levels from elements

  - by Moha

  If I have an array like this: Array ( [0] => field_schools [1] => und [2] => 0 [3] => field_school [4] => und [5] => 0 [6] => value ) How can I make an array like this from it? array ( [field_schools] => array ( [und] => array ( [0] => array ( [field_school] => array ( [und] => array ( [0] => array ( [value] => something ) ) ) ) ) ) ) I want to specify the 'value' myself.

• The next step for a graduate?

  - by Michael Hobbs

  I will complete my degree in Computer Science in July of 2013 however I will have two years of military service left. I would like to get some hands on C#/C++ programming experience in the mean time. I have been looking around the web at all the open source project that are out there. There are literally 10's of thousands. How would you go about picking one that is: A) good for a graduate level programmer B) will probably go somewhere, and C) are willing to take a novice under their wing. I would even be happy to work for a company for free, remotely as a debugger, tester, or what have you. As a side note would prefer to stick in the C# realm but understand I need to branch out at the same time.

• Inspecting the model in a Rails application

  - by Matt Sherman

  I am learning some Ruby on Rails, and am a newbie. Most of my background is in ASP.net MVC on the back end. As I play with a basic scaffold project, I wonder about this case: you jump into an established Rails project and want to get to know the model. Based on what I have seen so far (again, simple scaffold), the properties for a given class are not immediately revealed. I don't see property accessors on the model classes. I do understand that this is because of the dynamic nature of Ruby and such things are not necessary or even perhaps desirable. Convention over code, I get that. (Am familiar with dynamic concepts, mostly via JS.) But if I am somewhere off in a view, and want to quickly know whether the (eg) Person object has a MiddleName property, how would I find that out? I don't have to go into the migrations, do I?

• Ways to organize interface and implementation in C++

  - by Felix Dombek

  I've seen that there are several different paradigms in C++ concerning what goes into the header file and what to the cpp file. AFAIK, most people, especially those from a C background, do: foo.h class foo { private: int mem; int bar(); public: foo(); foo(const foo&); foo& operator=(foo); ~foo(); } foo.cpp #include foo.h foo::bar() { return mem; } foo::foo() { mem = 42; } foo::foo(const foo& f) { mem = f.mem; } foo::operator=(foo f) { mem = f.mem; } foo::~foo() {} int main(int argc, char *argv[]) { foo f; } However, my lecturers usually teach C++ to beginners like this: foo.h class foo { private: int mem; int bar() { return mem; } public: foo() { mem = 42; } foo(const foo& f) { mem = f.mem; } foo& operator=(foo f) { mem = f.mem; } ~foo() {} } foo.cpp #include foo.h int main(int argc, char* argv[]) { foo f; } // other global helper functions, DLL exports, and whatnot Originally coming from Java, I have also always stuck to this second way for several reasons, such as that I only have to change something in one place if the interface or method names change, that I like the different indentation of things in classes when I look at their implementation, and that I find names more readable as foo compared to foo::foo. I want to collect pro's and con's for either way. Maybe there are even still other ways? One disadvantage of my way is of course the need for occasional forward declarations.

• Software monetization that is not evil

  - by t0x1n

  I have a free open-source project with around 800K downloads to date. I've been contacted by some monetization companies from time to time and turned them down, since I didn't want toolbar malware associated with my software. I was wondering however, is there a non-evil way to monetize software ? Here are the options as I know them: Add a donation button. I don't feel comfortable with that as I really don't need "donations" - I'm paid quite well. Donating users may feel entitled to support etc. (see the second to last bullet) Add ads inside your application. In the web that may be acceptable, but in a desktop program it looks incredibly lame. Charge a small amount for each download. This model works well in the mobile world, but I suspect no one will go for it on the desktop. It doesn't mix well with open source, though I suppose I could charge only for the binaries (most users won't go to the hassle of compiling the sources). People may expect support etc. after having explicitly paid (see next bullet). Make money off a service / community / support associated with the program. This is one route I definitely don't want to take, I don't want any sort of hassle beyond coding. I assure you, the program is top notch (albeit simple) and I'm not aware of any bugs as of yet (there are support forums and blog comments where users may report them). It is also very simple, documented, and discoverable so I do think I have a case for supplying it "as is". Add affiliate suggestions to your installer. If you use a monetization company, you lose control over what they propose. Unless you can establish some sort of strong trust with the company to supply quality suggestions (I sincerely doubt it), I can't have that. Choosing your own affiliate (e.g. directly suggesting Google Toolbar) is possibly the only viable solution to my mind. Problem is, where do I find a solid affiliate that could actually give value to the user rather than infect his computer with crapware? I thought maybe Babylon (not the toolbar of course, I hate toolbars)?

• What effects do various drugs have on coding style / productivity? [closed]

  - by codecraft

  Can anyone tell me what the effect of various drugs are on coding style, and if coding on drugs can be more productive, or more fun? Are some types of drugs better suited to certain tasks and phases of software development? And which programming languages are best suited to coding on drugs? It would be great if you could back up your answers by data, probably even code snippets showcasing the effect of the drug experience.

• Just interviewed, turned down, now got an email asking to chat with recruiter. No response. What should I do? [closed]

  - by Lambert

  I was turned down after two interviews by a prominent company for an internship, and only a couple days later, I was asked when I had 10-15 minutes to chat today. Of course, I loved to, so I emailed within just 10 minutes of their email and let them know what times I was available at, and asked them when the best time should be, and if I should go somewhere or expect a phone call. No reply has come from them since yesterday afternoon, the recruiter wanted to talk to me today. I don't want to lose this opportunity, but I have no way to contact the recruiter other than by email, and the recruiter hasn't responded to my emails from yesterday, even though we were supposed to talk today. What's the best thing I can do (preferably within the next few hours!) to get the job? Is that even probably why she emailed me, or was a different reason likely? Any ideas?

• XML parsing and transforming (XSLT or otherwise)

  - by observ

  I have several xml files that are formated this way: <ROOT> <OBJECT> <identity> <id>123</id> </identity> <child2 attr = "aa">32</child2> <child3> <childOfChild3 att1="aaa" att2="bbb" att3="CCC">LN</childOfChild3> </child3> <child4> <child5> <child6>3ddf</child6> <child7> <childOfChild7 att31="RR">1231</childOfChild7> </child7> </child5> </child4> </OBJECT> <OBJECT> <identity> <id>124</id> </identity> <child2 attr = "bb">212</child2> <child3> <childOfChild3 att1="ee" att2="ccc" att3="EREA">OP</childOfChild3> </child3> <child4> <child5> <child6>213r</child6> <child7> <childOfChild7 att31="EE">1233</childOfChild7> </child7> </child5> </child4> </OBJECT> </ROOT> How can i format it this way?: <ROOT> <OBJECT> <id>123</id> <child2>32</child2> <attr>aa</attr> <child3></child3> <childOfChild3>LN</childOfChild3> <att1>aaa</att1> <att2>bbb</att2> <att3>CCC</att3> <child4></child4> <child5></child5> <child6>3ddf</child6> <child7></child7> <childOfChild7>1231</childOfChild7> <att31>RR</att31> </OBJECT> <OBJECT> <id>124</id> <child2>212</child2> <attr>bb</attr> <child3></child3> <childOfChild3>LN</childOfChild3> <att1>ee</att1> <att2>ccc</att2> <att3>EREA</att3> <child4></child4> <child5></child5> <child6>213r</child6> <child7></child7> <childOfChild7>1233</childOfChild7> <att31>EE</att31> </OBJECT> </ROOT> I know some C# so maybe a parser there? or some generic xslt? The xml files are some data received from a client, so i can't control the way they are sending it to me. L.E. Basically when i am trying to test this data in excel (for example i want to make sure that the attribute of childOfChild7 corresponds to the correct identity id) i am getting a lot of blank spaces. If i am importing in access to get only the data i want out, i have to do a thousands subqueries to get them all in a nice table. Basically i just want to see for one Object all its data (one object - One row) and then just delete/hide the columns i don't need.

• Reconstruct a file from a TCP stream

  - by Abhishek Chanda

  I have a client and a server and a third box which sees all packets from the server to the client (but not the other way around). Now when the client requests a file from the server (over HTTP), the third box sees the response. I am trying to reconstruct the file there. I am using libpcap to capture TCP datagrams and trying to reconstruct the file there. Here is what I did Listen for packets on an interface Group all packets which have the same ACK number Sort the group based on SEQ number Extract data from each packet and combine them and write to the disk The problem is, the file thus generated is not exactly the same as the original file. Does everything sound correct here? Some more details: I am using C++ The packet data is being stored as std::vector<char> I did change the byte order while reading the ack number and seq number from the packet using ntohl I am not sure if I need to change the byte order for the data as well. I tried to reverse the data from each packet before combining them, even that did not work. Is there something I am missing?

• CS Concentrations and Career Paths

  - by xbonez

  I'm approaching the end of Sophomore year in college (Studying Computer Science), and very soon I'm going to have to decide on my concentration, but I honestly don't know what each concentration means. I basically have two questions: 1. How much influence does your concentration have on your career path? For example, would a video game development company only look at people with a concentration in Game Development? 2.It would be great if you guys could, in a line or two, tell me what sort of jobs am I looking at for each of the concentrations? I need to pick at least two of the 9 below. - Algorithms and Data Structures - Artificial Intelligence - Computer and Network Society - Computer graphics and vision - Human-Computer Interaction - Game Development and Design - Numeric and Symbolic Computation - Programming languages - Systems

• How to avoid mediocre CV.

  - by QriousCat

  Though in every project we (testers) face different set challenges, when it comes to CV, more or less we have same responsibilities. For example responsibilities like understanding requirements, preparing and executing test cases, creating defects, liaising with dev, BA teams will be repeated for every project we involve. If we keep writing same responsibilities for every role, CV becomes mediocre and a yarn. In fact most of the testing resumes I have come across are like that. How do I avoid repetition of responsibilities in my resume and make it more interesting? If this is not the correct forum for this question let me know. Thanks in advance for your suggestions.

• 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.

• Trial/Free & Full Version VS. Free App + In-app billing?

  - by SERPRO

  I'm just wondering what would be the best strategy to publish an application on the Android Market. If you have a free and paid version you have two codes to update (I know it will be 99% the same but still) and besides all the popular paid apps are quite easy to find for "free" in "alternative" markets. Also if you have any stored data in the trial/free version you lose it when you buy the full version.. On the other hand if you put a free application but inside you allow the user to unlock options (remove ads/more settings/etc...) you only have to worry about one code. I don't know the drawbacks of that strategy and how easy/hard is to hack that to get all the options for "free".

• Real performance of node.js

  - by uther.lightbringer

  I've got a question concerning node.js performance. There is quite lot of "benchmarks" and a lot of fuss about great performance of node.js. But how does it stand in real world? Not just process empty request at high speed. If someone could try to compare this scenario: Java (or equivalent) server running an application with complex business logic between receiving request and sending response. How would node.js deal with it? If there was need for a lot of JavaScript processing on server side, is node.js really so fast that it can execute JavaScript, and stand a chance against more heavyveight competitors?

• comparison of an unsigned variable to 0

  - by user2651062

  When I execute the following loop : unsigned m; for( m = 10; m >= 0; --m ){ printf("%d\n",m); } the loop doesn't stop at m==0, it keeps executing interminably, so I thought that reason was that an unsigned cannot be compared to 0. But when I did the following test unsigned m=9; if(m >= 0) printf("m is positive\n"); else printf("m is negative\n"); I got this result: m is positive which means that the unsigned variable m was successfully compared to 0. Why doesn't the comparison of m to 0 work in the for loop and works fine elsewhere?

• Prepared statement alternatives for this middle-man program?

  - by user2813274

  I have an program that is using a prepared statement to connect and write to a database working nicely, and now need to create a middle-man program to insert between this program and the database. This middle-man program will actually write to multiple databases and handle any errors and connection issues. I would like advice as to how to replicate the prepared statements such as to create minimal impact to the existing program, however I am not sure where to start. I have thought about creating a "SQL statement class" that mimics the prepared statement, only that seems silly. The existing program is in Java, although it's going to be networked anyways so I would be open to writing it in just about anything that would make sense. The databases are currently MySQL, although I would like to be open to changing the database type in the future. My main question is what should the interface for this program look like, and does doing this even make sense? A distributed DB would be the ideal solution, but they seem overly complex and expensive for my needs. I am hoping to replicate the main functionality of a distributed DB via this middle-man. I am not too familiar with sql-based servers distributing data (or database in general...) - perhaps I am fighting an uphill battle by trying to solve it via programming, but I would like to make an attempt at least.

• Standard -server to server- and -browser to server- authentication method

  - by jeruki

  I have server with some resources; until now all these resources were requested through a browser by a human user, and the authentication was made with an username/password method, that generates a cookie with a token (to have the session open for some time). Right now the system requires that other servers make GET requests to this resource server but they have to authenticate to get them. We have been using a list of authorized IPs but having two authentication methods makes the code more complex. My questions are: Is there any standard method or pattern to authenticate human users and servers using the same code? If there is not, are the methods I'm using now the right ones or is there a better / more standard way to accomplish what I need? Thanks in advance for any suggestion.

• Design for object with optional and modifiable attributtes?

  - by Ikuzen

  I've been using the Builder pattern to create objects with a large number of attributes, where most of them are optional. But up until now, I've defined them as final, as recommended by Joshua Block and other authors, and haven't needed to change their values. I am wondering what should I do though if I need a class with a substantial number of optional but non-final (mutable) attributes? My Builder pattern code looks like this: public class Example { //All possible parameters (optional or not) private final int param1; private final int param2; //Builder class public static class Builder { private final int param1; //Required parameters private int param2 = 0; //Optional parameters - initialized to default //Builder constructor public Builder (int param1) { this.param1 = param1; } //Setter-like methods for optional parameters public Builder param2(int value) { param2 = value; return this; } //build() method public Example build() { return new Example(this); } } //Private constructor private Example(Builder builder) { param1 = builder.param1; param2 = builder.param2; } } Can I just remove the final keyword from the declaration to be able to access the attributes externally (through normal setters, for example)? Or is there a creational pattern that allows optional but non-final attributes that would be better suited in this case?

• Android Card Game Database for Deck Building

  - by Singularity222

  I am making a card game for Android where a player can choose from a selection of cards to build a deck that would contain around 60 cards. Currently, I have the entire database of cards created that the user can browse. The next step is allowing the user to select cards and create a deck with whatever cards they would like. I have a form where the user can search for specific cards based off a few different attributes. The search results are displayed in a List Activity. My thought about deck creation is to add the primary key of each card the user selects to a SQLite Database table with the amount they would like in the deck. This way as the user performs searches for cards they can see the state of the deck. Once the user decides to save the deck. I'll export the card list to XML and wipe the contents of the table. If the user wanted to make changes to the deck, they would load it, it would be parsed back into the table so they could make the changes. A similar situation would occur when the eventually load the deck to play a game. I'm just curious what the rest of you may think of this method. Currently, this is a personal project and I am the only one working on it. If I can figure out the best implementation before I even begin coding I'm hoping to save myself some time and trouble.

• How to represent an agile project to people focused on waterfall [closed]

  - by ahsteele

  Our team has been asked to represent our development efforts in a project plan. No one is unhappy with our work or questioning our ability to deliver, we are just participating in an IT cattle call for project plans. Trouble is we are an agile team and haven't thought about our work in terms of a formal project plan. While we have a general idea of what we are working on next we aren't 100% sure until we plan an iteration. Until now our team has largely operated in a vacuum and has not been required to present our methodology or metrics to outside parties. We follow most of the practices espoused in Extreme Programming. We hold quarterly planning meetings to have a general idea of the stories we are going to work on for a quarter. That said, our stories are documented on 3x5 cards and are only estimated at the beginning of the iteration in which they are going to be worked. After estimation we document the story in Team Foundation Sever. During an iteration, we attach code to stories and mark stories as completed once finished. From this data we are able to generate burn down and velocity charts. Most importantly we know our average velocity for an iteration keeping us from biting off more than we can chew. I am not looking to modify the way we do development but want to present our development activities in a report that someone only familiar with waterfall will understand. In What Does an Agile Project Plan Look Like, Kent McDonald does a good job laying out the differences between agile and waterfall project plans. He specifies the differences in consumable bullets: An agile project plan is feature based An Agile Project Plan is organized into iterations An Agile Project Plan has different levels of detail depending on the time frame An Agile Project Plan is owned by the Team Being able to explain the differences is great, but how best to present the data?

• How many questions is it appropriate to ask as an intern?

  - by Casey Patton

  So, I just started an internship, and I'm worried that I'm asking too many questions. My mentor assigns me projects and helps me learn all the company's technologies and methodologies. However, there's so much new material for me to learn while doing this project that I have a lot of questions. I generally ask questions over instant messages or E-mail (those are the primary modes of communication for my company). I'm trying to be careful not to ask too many questions: I don't want to come off as annoying or dumb. How many questions are appropriate to ask? Once an hour? More? Less? Keep in mind, my mentor is also a fellow programmer who has his own responsibilities.

• Getting My Head Around Immutability

  - by Michael Mangold

  I'm new to object-oriented programming, and one concept that has been taking me a while to grasp is immutability. I think the light bulb went off last night but I want to verify: When I come across statements that an immutable object cannot be changed, I'm puzzled because I can, for instance, do the following: NSString *myName = @"Bob"; myName = @"Mike"; There, I just changed myName, of immutable type NSString. My problem is that the word, "object" can refer to the physical object in memory, or the abstraction, "myName." The former definition applies to the concept of immutability. As for the variable, a more clear (to me) definition of immutability is that the value of an immutable object can only be changed by also changing its location in memory, i.e. its reference (also known as its pointer). Is this correct, or am I still lost in the woods?
