• a young intellect asks: Python or Ruby for freelance?

  - by Sophia

  Hello, I'm Sophia. I have an interest in self-learning either Python, or Ruby. The primary reason for my interest is to make my life more stable by having freelance work = $. It seems that programming offers a way for me to escape my condition of poverty (I'm on the edge of homelessness right now) while at the same time making it possible for me to go to uni. I intend on being a math/philosophy major. I have messed with Python a little bit in the past, but it didn't click super well. The people who say I should choose Python say as much because it is considered a good first language/teaching language, and that it is general-purpose. The people who say I should choose Ruby point out that I'm a very right-brained thinker, and having multiple ways to do something will make it much easier for me to write good code. So, basically, I'm starting this thread as a dialog with people who know more than I do, as an attempt to make the decision. :-) I've thought about asking this in stackoverflow, but they're much more strict about closing threads than here, and I'm sort of worried my thread will be closed. :/ TL;DR Python or Ruby for freelance work opportunities ($) as a first language? Additional question (if anyone cares to answer): I have a personal feeling that if I devote myself to learning, I'd be worth hiring for a project in about 8 weeks of work. I base this on a conservative estimate of my intellectual capacities, as well as possessing motivation to improve my life. Is my estimate necessarily inaccurate? random tidbit: I'm in Portland, OR I'll answer questions that are asked of me, if I can help the accuracy and insight contained within the dialog.

• How is dependency inversion related to higher order functions?

  - by Gulshan

  Today I've just seen this article which described the relevance of SOLID principle in F# development- F# and Design principles – SOLID And while addressing the last one - "Dependency inversion principle", the author said: From a functional point of view, these containers and injection concepts can be solved with a simple higher order function, or hole-in-the-middle type pattern which are built right into the language. But he didn't explain it further. So, my question is, how is the dependency inversion related to higher order functions?

• What is a widely accepted term for a string variable that would probably contain a file path and file name?

  - by Peter Turner

  For functions that need to index files in a directory and rename them FileName0001, FileName0002, etc... I often need to write a function that splits the file name from the file path and rename the file. When I put the file name and file path back together, I don't have a very good name for the variable that contains both of them and I usually just wind up concatenating them every time I want to use them (usually using them as parameters for functions labeled either filename or filepath) so I never really know what I'm doing until I notice a lot of files being written in the same directory as my binaries. Anyway, what do I call a file name and a file path? I don't want to call it File, because that usually means the binary information behind the file. I don't want to call it URI because that usually means I've got some sort of protocol, which I don't. I just want a good way to denote "c:\somedir\somedir\somedir\somefile.txt" so as to deconfuse this mess I've just realized I'm in. Please don't just list your personal preference. I think an excellent answer should "'site its sources". (as in, provide a link to a repository with a good example of the code being used as I described)

• How can I compare between web development technologies?

  - by Steve

  I would like experts to explain for me how can I compare between web development tools or technologies in order to be able to choose the right one. I'm tired from searching always in the regular way: X Technology vs Y Technology. I'm tired from peoples' biased opinions and usually I don't find a fair comparison. I have decided to put my question here about how can I compare them so you may identify to me the main standards for comparisons so I can compare them by myself and becoming able to choose the technology that is appropriate for the project I will develop. Note: in web development technologies I mean server side languages (e.g. PHP). One important requirement for me that can be defined as major one is cost efficiency and I mean that I don't care about the cost in the near future or the current cost, but what is more important for me is the cost in the future. If, for example, the site becomes one of the most 100 visited sites.   So, how can I compare the cost of different technologies for a future status of a site (such as being very famous site) so I can scale my option easily without missing a good technology like what happened with some sites when they chose not the most effective tool.

• JQuery / JSON + .Net Service Layer - to WCF or Not to WCF?

  - by hanzolo

  I Recently had a discussion with a colleague of mine about the pros / cons of WCF. He mentioned about how much code is generated to support WCF, and also the overhead required. It was mentioned that a simple jQuery /Ajax post to a .aspx page (or a handler for that matter) that returns JSON would work more efficiently and takes much less code to implement. I am also aware of the new WCF Web API and feel that technology may solve the "bloated"-ness required in attaining a proxy etc... by just outputting JSON. So when developing a relational DB (MSSQL) storage model, with a fairly complex Business Layer (C#) and Data Access Layer (EntityFW).. what's a good technology for creating a "service layer" which will spit out View Models represented in JSON, with a CQRS(Command Query..) approach in mind.. The app would use the service layer to support it's required UI, as well as provide an available subset of services (outputting JSON data) for service subscribers.. In other words an admin panel to support the admin UI, and service endpoints that return JSON to access the configurations made from the administration UI. What are some potential technologies to use as the transport / communication layer. I'd like to use a pure RESTful approach, but am not against doing some URL rewriting with IIS. Obviously some of the available technologies are: WCF WCF Web API (should this even be separate?) Straight request / response (query string to .aspx / handler) Would using MVC .Net solve this entire problem? maybe their single page app approach? any suggestions / feedback from developing this type of application? Thanks,

• Communication between WCF service [library] and Self-host [Winform]

  - by Mur Haf Soz

  Introduction: I have a WCF service library and a self-host Winform. Service features is File explorer including (copy, move, delete, new folder, delete... etc) and Task Manager (run, kill, update list). Then now I want to add other features like chatting between self-host and client, send an image from client to self-host so when it received, it is shown in a pictureBox in a new form. Till now I have two endpoints for (Task Manager, File Manager) that runs under one service "MainService". And I set up all the connections using DotNet 4.0 WCF Configuration and Wizards, and I'm using netTcpBinding. Problem: I need to know how to communicate with between WCF service lib and self-host, so I can append a received chat from client on self-host form's textbox TextBoxChat. And also call a client callback from self-host when Send button clicked, to send the message from self-host textbox TextBoxMessage. Let's say this's self-host ChatForm So is it possible to do that in WCF? I would prefer to run ChatEndpoint under MainService, so all Endpoints use one port.

• unit/integration testing web service proxy client

  - by cori

  I'm rewriting a PHP client/proxy library that provides an interface to a SOAP-based .Net webservice, and in the process I want to add some unit and integration tests so future modifications are less risky. The work the library I'm working on performs is to marshall the calls to the web service and do a little reorganizing of the responses to present a slightly more -object-oriented interface to the underlying service. Since this library is little else than a thin layer on top of web service calls, my basic assumption is that I'll really be writing integration tests more than unit tests - for example, I don't see any reason to mock away the web service - the work that's performed by the code I'm working on is very light; it's almost passing the response from the service right back to its consumer. Most of the calls are basic CRUD operations: CreateRole(), CreateUser(), DeleteUser(), FindUser(), &ct. I'll be starting from a known database state - the system I'm using for these tests is isolated for testing purposes, so the results will be more or less predictable. My question is this: is it natural to use web service calls to confirm the results of operations within the tests and to reset the state of the application within the scope of each test? Here's an example: One test might be createUserReturnsValidUserId() and might go like this: public function createUserReturnsValidUserId() { // we're assuming a global connection to the service $newUserId = $client->CreateUser("user1"); assertNotNull($newUserId); assertNotNull($client->FindUser($newUserId); $client->deleteUser($newUserId); } So I'm creating a user, making sure I get an ID back and that it represents a user in the system, and then cleaning up after myself (so that later tests don't rely on the success or failure of this test w/r/t the number of users in the system, for example). However this still seems pretty fragile - lots of dependencies and opportunities for tests to fail and effect the results of later tests, which I definitely want to avoid. Am I missing some options of ways to decouple these tests from the system under test, or is this really the best I can do? I think this is a fairly general unit/integration testing question, but if it matters I'm using PHPUnit for the testing framework.

• Is it a bug or a task when something doesn't work, yet, in development process

  - by Patkos Csaba

  We usually have this dilemma in our team. Sometimes, in order to implement a task or a story we find out that the system must be in a specific state. For example, a specific system configuration has to be made beforehand. The task / story can be completed and it is working as specified on it with the proper configuration in place. Note that the configuration is not directly related with the task. Next, we have to create a new ... ??? ... something for the process of generating that configuration file. This is where the problems appear. Some say that it is a bug others say it is a task or an extra feature. So, where is the limit between bugs and tasks in the development phase? Should we even consider something a bug if all the tasks are working as stated in their definitions? Can a thing be considered a bug because one compares it to the current (unstable) state of the system? Short example: A feature requires configuring a communication service for a specific operation. In the process of the implementation the team discovers that the service requires the hostnames of the pears to be resolvable to an IP address. The team adds the hostnames to the DNS server (or hosts files) and continues implementing the required feature. After the initial feature is working, a question is risen. Should the sysadmin configure the DNS or hosts file or should our application do it automatically? An automatic solution is possible. So a decision is made to implement it. ... here start the discussions ... is this a bug or an extra feature / task? PS: I know that I mixed feature / task / story in the question. It is intentional. I am interested in separating bugs from the rest. Doesn't matter what the rest means in a particular case.

• how to improve design ability

  - by Cong Hui

  I recently went on a couple of interviews and all of them asked a one or two design questions, like how you would design a chess, monopoly, and so on. I didn't do good on those since I am a college student and lack of the experience of implementing big and complex systems. I figure the only way to improve my design capability is to read lots of others' code and try to implement myself. Therefore, for those companies that ask these questions, what are their real goals in this? I figure most of college grads start off working in a team guided by a senior leader in their first jobs. They might not have lots of design experience fresh out of colleges. Anyone could give pointers about how to practice those skills? Thank you very much

• I need some career guidance, please.

  - by user18956

  Hi, I have been a teacher of guitar and music theory for the last ten years or so, and I have decided to get out of it and pursue something involving computers, but I am very confused about it all. I have no training related to programming besides a knowledge of xhtml and css - which I realize are not even programming languages. My problem is that I know I want to do something with either making video games, computer/online applications, or some other programming job, but I haven't a clue how to begin. I picked up a book from the Head First series entitled, Head First Programming that uses Python to teach programming concepts, but after that, I don't really know what is a good direction for me in terms of balancing career satisfaction with job availability and acceptable pay. I am not looking for a huge salary, I just want to be able to survive doing something I love, and which challenges me. I don't know even a single person involved in a related field, so I am in need of guidance. The first thing I would like to know is whether pursuing a career as a programmer for video games is a realistic option. I love video games, and play them all the time, and I have always wanted to make them. If this is an option, what would be the recommended course of action? What is a good language or technology to get involved in for the job market now? I have read that PHP/MySQL is a good place to find a job for some. Can I find a job without school, or do I need to got o college? Also, will the Python I learn in this book translate into any other language I need to learn? If it is anything like music, then I am sure it will, but I don't know much about programming - yet. And last, yet perhaps most important, is thirty years old too old to take such a radical redirection in careers? Thank you for any help you can offer. I really need it.

• Is functional programming a superset of object oriented?

  - by Jimmy Hoffa

  The more functional programming I do, the more I feel like it adds an extra layer of abstraction that seems like how an onion's layer is- all encompassing of the previous layers. I don't know if this is true so going off the OOP principles I've worked with for years, can anyone explain how functional does or doesn't accurately depict any of them: Encapsulation, Abstraction, Inheritance, Polymorphism I think we can all say, yes it has encapsulation via tuples, or do tuples count technically as fact of "functional programming" or are they just a utility of the language? I know Haskell can meet the "interfaces" requirement, but again not certain if it's method is a fact of functional? I'm guessing that the fact that functors have a mathematical basis you could say those are a definite built in expectation of functional, perhaps? Please, detail how you think functional does or does not fulfill the 4 principles of OOP.

• Design pattern for logging changes in parent/child objects saved to database

  - by andrew

  I’ve got a 2 database tables in parent/child relationship as one-many. I’ve got three classes representing the data in these two tables: Parent Class { Public int ID {get; set;} .. other properties } Child Class { Public int ID {get;set;} Public int ParentID {get; set;} .. other properties } TogetherClass { Public Parent Parent; Public List<Child> ChildList; } Lastly I’ve got a client and server application – I’m in control of both ends so can make changes to both programs as I need to. Client makes a request for ParentID and receives a Together Class for the matching parent, and all of the child records. The client app may make changes to the children – add new children, remove or modify existing ones. Client app then sends the Together Class back to the server app. Server app needs to update the parent and child records in the database. In addition I would like to be able to log the changes – I’m doing this by having 2 separate tables one for Parent, one for child; each containing the same columns as the original plus date time modified, by whom and a list of the changes. I’m unsure as to the best approach to detect the changes in records – new records, records to be deleted, records with no fields changed, records with some fields changed. I figure I need to read the parent & children records and compare those to the ones in the Together Class. Strategy A: If Together class’s child record has an ID of say 0, that indicates a new record; insert. Any deleted child records are no longer in the Together Class; see if any of the comparison child records are not found in the Together class and delete if not found (Compare using ID). Check each child record for changes and if changed log. Strategy B: Make a new Updated TogetherClass UpdatedClass { Public Parent Parent {get; set} Public List<Child> ListNewChild {get;set;} Public List<Child> DeletedChild {get;set;} Public List<Child> ExistingChild {get;set;} // used for no changes and modified rows } And then process as per the list. The reason why I’m asking for ideas is that both of these solutions don’t seem optimal to me and I suspect this problem has been solved already – some kind of design pattern ? I am aware of one potential problem in this general approach – that where Client App A requests a record; App B requests same record; A then saves changes; B then saves changes which may overwrite changes A made. This is a separate locking issue which I’ll raise a separate question for if I’ve got trouble implementing. The actual implementation is c#, SQL Server and WCF between client and server - sharing a library containing the class implementations. Apologies if this is a duplicate post – I tried searching various terms without finding a match though.

• Design of input files reading when it comes to defaults/transformations

  - by Stefano Borini

  Suppose you have an application that reads an input file, on a language that does not support the concept of None. The input is read, parsed, and the contents are stored on a structure for later use. Now, in general you want to keep into account transformation of the data from the input, such as adding default values when not specified, or adding full path information to relative path specified in the input. There are two different strategies to achieve this. The first strategy is to perform these transformations at input file reading time. In practice, you put all the intelligence into the input parser, and your application has no logic to deal with unexpected circumstances, such as an unspecified value. You lose the information of what was specified and what wasn't, but you gain in black-boxing the details. Your "running code" needs that information in any case and in a proper form, and is not concerned if it's the default or a user-specified information. The second strategy is to have the file reader a real one-to-one mapper from the file to a memory-stored object, with no intelligent behavior. unspecified values are not filled (which may however be a problem in languages not supporting None) and data is stored verbatim from the file. The intelligence for recovery must now go into the "running code", which must check what was specified in the file, eventually fall back to a default, or modify the input properly before using it. I would like to know your opinion on these two approaches, and in particular which one you found the most frequently implemented.

• Why do I have to choose between "management" and "technical" tracks in my career?

  - by Stephen Gross

  I was recently laid off, and although I found a new gig I'm a bit frustrated with how career tracks work in the land of software development. I really love doing a bit of everything: coding, testing, architect(ing), leadership/management, customer contact, requirements gathering, staff development, etc. Software companies, however, want me to fit into a niche: I'm either a coder, a tester, or a manager. When I try to explain to them that I'm best when I'm doing all of those at once, they seem very confused. I'm sympathetic to their interests, but at the same time frustrated that the industry works this way. Any advice? Do I just need to get with the program, so to speak?

• How can I unit test a class which requires a web service call?

  - by Chris Cooper

  I'm trying to test a class which calls some Hadoop web services. The code is pretty much of the form: method() { ...use Jersey client to create WebResource... ...make request... ...do something with response... } e.g. there is a create directory method, a create folder method etc. Given that the code is dealing with an external web service that I don't have control over, how can I unit test this? I could try and mock the web service client/responses but that breaks the guideline I've seen a lot recently: "Don't mock objects you don't own". I could set up a dummy web service implementation - would that still constitute a "unit test" or would it then be an integration test? Is it just not possible to unit test at this low a level - how would a TDD practitioner go about this?

• Getting rid of getting stuck often [closed]

  - by Pankaj Upadhyay

  I have been working with C# and .NET for around 2-3 years. But, still i get stuck too often. My project includes few simple websites(asp.net) in the early parts and then a desktop application for cotton transaction management(wpf). And right now, I am building a price compare website (asp.net MVC). Along the lines, I have read quite few books on C# and .NET, but still I get stuck very often. What pisses me is that the problems I get stuck in aren't very typical or hard. You can get a better idea by visiting my questions page on SO. After looking at my question lists, do you also feel that my basis or knowledge as a programmer are weak ? If so, How can i find a remedy to this problem ? And How can I stop getting stuck too often for simpler problems.

• Who are the outspoken critics of Object-Oriented design?

  - by Xepoch

  Sure, object-oriented techniques are great and have stuck around for a while. I know only less than a handful of critics of the OO principles. It seems as though most non-OO designs and architectures are shunned, yet we continue to write a lot of good software in C and solve a lot of data changes via awk/sed and countless other examples. Correct tool for the correct job, yes? I'm having a hard time finding articles, presentations, or published criticisms of OO (even Fred Brooks has blessed information hiding). Are there any well-known, published and/or outspoken critics of OO?

• Business Logic Layer in MVC Application

  - by Subin Jacob

  In my ASP MVC application I decided to add another Business Layer and made the model only to have properties. All other functionality like save to db, get from db is done on this new Business layer. So now the controller will be calling this business layer and model for various operations. Is it a good approach to design like this? I decided not to use model for this purpose because I would need a number of models for different actions. (for eg, one for edit and other for create)

• How to learn the math behind the code?

  - by Solomon Wise

  I am a 12 year old who has recently gotten into programming. (Although I know that the number of books you have read does not determine your programming competency or ability, just to paint a "map" of where I am in terms of the content I know...) I've finished the books: Python 3 For Absolute Beginners Pro Python Python Standard Library by Example Beautiful Code Agile Web Development With Rails and am about halfway into Programming Ruby. I have written many small programs (One that finds which files have been updated and deleted in a directory, one that compares multiple players' fantasy baseball value, and some text based games, and many more). Obviously, as I'm not some sort of child prodigy, I can't take a formal Computer Science course until high school. I really want to learn computer science to increase my knowledge about the code, and the how the code runs. I've really become interested in the math part after reading the source code for Python's random module. Is there a place where I can learn CS, or programming math online for free, at a level that would be at least partially understandable to a person my age?

• JS closures - Passing a function to a child, how should the shared object be accessed

  - by slicedtoad

  I have a design and am wondering what the appropriate way to access variables is. I'll demonstrate with this example since I can't seem to describe it better than the title. Term is an object representing a bunch of time data (a repeating duration of time defined by a bunch of attributes) Term has some print functionality but does not implement the print functions itself, rather they are passed in as anonymous functions by the parent. This would be similar to how shaders can be passed to a renderer rather than defined by the renderer. A container (let's call it Box) has a Schedule object that can understand and use Term objects. Box creates Term objects and passes them to Schedule as required. Box also defines the print functions stored in Term. A print function usually takes an argument and uses it to return a string based on that argument and Term's internal data. Sometime the print function could also use data stored in Schedule, though. I'm calling this data shared. So, the question is, what is the best way to access this shared data. I have a lot of options since JS has closures and I'm not familiar enough to know if I should be using them or avoiding them in this case. Options: Create a local "reference" (term used lightly) to the shared data (data is not a primitive) when defining the print function by accessing the shared data through Schedule from Box. Example: var schedule = function(){ var sched = Schedule(); var t1 = Term( function(x){ // Term.print() return (x + sched.data).format(); }); }; Bind it to Term explicitly. (Pass it in Term's constructor or something). Or bind it in Sched after Box passes it. And then access it as an attribute of Term. Pass it in at the same time x is passed to the print function, (from sched). This is the most familiar way for my but it doesn't feel right given JS's closure ability. Do something weird like bind some context and arguments to print. I'm hoping the correct answer isn't purely subjective. If it is, then I guess the answer is just "do whatever works". But I feel like there are some significant differences between the approaches that could have a large impact when stretched beyond my small example.

• Carpool logical architecture

  - by enrmarc

  I'm designing a carpool system (drivers can publish their routes and passengers can subscribe to them) with WebServices(axis2) and Android clients (ksoap2). I have been having problems with the logical architecture of the system and I wondered if this architecture is fine. And another question: for that architecture (if it is ok), how would be the packages structure? I suppose something like that: (In android) package org.carpool.presentation *All the activities here (and maybe mvc pattern) (In the server) package org.carpool.services *Public interfaces (for example: register(User user), publishRoute(Route route) ) package org.carpool.domain *Pojos (for example: User.java, Route.java, etc) package org.carpool.persistence *Dao Interface and implementation (jdbc or hibernate)

• What tools exist for assessing an organisation's development capability?

  - by Eric Smith

  I have a bit of a challenge at work at the moment. Presently (and in fact, for some time now), we have been experiencing the following problems with some in-house maintained applications: Defects (sometimes quite serious) being released into production; The Customer (that is, the relevant business unit) perpetually changing their minds (or appearing to do so) about what issue to work on next; A situation where everyone seems to be in a "fire-fighting" mode a lot of the time; Development staff responding to operational requests from business users; ("operational" here means something that needs to be done in order to continue with business, or perhaps just to make a business user's life a little less painful, as opposed to fixing a bug in the application, or enhancing the application); Now I'm sure this doesn't sound particularly new or surprising to most of the participants on this Q&A site and no prizes for identifying the "usual suspects" when it comes to root causes. My challenge is that I have to persuade the higher-ups to do uncomfortable things in order to address all of this. The folk I need to persuade come from a mixture of the following two cultures: Accounting; IT Infrastructure. I have therefore opted for a strategy that draws from things with-which folk from such a culture would be most comfortable (at least, in my estimation), namely: numbers and tangibles. Of course modern development practitioners know all too well that this sort of thing isn't easily solved using an analytical mindset (some would argue that that mindset is, in fact, entirely inappropriate). Never-the-less, this is the dichotomy with-which I am faced, so that's the stake that I've put in the ground. I would like to be able to do research and use the outputs to present findings in the form of metrics and measures. I am finding it quite difficult, though, to find an agreed-upon methodology and set of templates for assessing an organisations development capability--the only thing that seems applicable is the Software Engineering Institute's Capability Maturity Model. The latter, however, seems dated and even then rather vague. So, the question is: Do any tools or methodologies (free or commercial) exist that would assist me in completing this assessment?

• How to better integrate a unix development environment into Windows

  - by SKenz

  I'm mostly a Windows user but I do most of my development (essentially web development) using unix tools and software. I've been going back and forth between using a dedicated lubuntu virtual machine on Virtualbox and using some tools directly in windows (msgit, python, django), but none of these approaches is entirely satisfactory. I'd like to hear of ways other devs use to better integrate a unix workflow into windows. For instance tighter integration between a linux and vm and windows. The vagrant demo showed how a VM could work off of a windows project folder and I found that nice. I'd like to hear of other tools and tips that would help mimic the workflow one can find on OS X (of course I understand that it cannot be as tightly integrated on Windows as it doesn't have the same unix underpinnings). PS: I have tried cygwin as well EDIT for clarifications about What I find lacking (thanks to axblount for pointing that out) : unix tools like msys et al do not work as well as their native unic counterparts. Many scripts, installers require further configuration or do not work at all. For instance getting virtualenvwrapper to work is not very straightforward. virtualbox: ideally I would like to use windows software (photoshop, sublime text 2) seamlessly with linux. I mostly use a FTP client atm to move over files edited on the windows side which is a tedious process.
