• How does a search functionality fit in DDD with CQRS?

  - by Songo

  In Vaughn Vernon's book Implementing domain driven design and the accompanying sample application I found that he implemented a CQRS approach to the iddd_collaboration bounded context. He presents the following classes in the application service layer: CalendarApplicationService.java CalendarEntryApplicationService.java CalendarEntryQueryService.java CalendarQueryService.java I'm interested to know if an application will have a search page that feature numerous drop downs and check boxes with a smart text box to match different search patterns; How will you structure all that search logic? In a command service or a query service? Taking a look at the CalendarQueryService.java I can see that it has 2 methods for a huge query, but no logic at all to mix and match any search filters for example. I've heard that the application layer shouldn't have any business logic, so where will I construct my dynamic query? or maybe just clutter everything in the Query service?

• Infix vs Prefix Notation - Which do you prefer?

  - by Jetti

  I have been learning Clojure and looking at Scheme and CL which introduced me to the world of prefix notation. At first I didn't like it but it is still starting to grow on me. To be honest though, there are still long calculations that are difficult for me to understand but I think that is an issue of me needing more exposure/practice and I'll get it. But that leads me to the question: Which type of notation do you prefer and why?

• Mail Scanning System

  - by Mr D

  In the same way gmail can generate ads based on email content, I am looking for a way to develop a system which can: Allow users to connect their email address to our site It then would continously monitor all incomming emails From the incomming emails there would be a critera(e.g. a certain address or subject) if any of the emails matched the critea it would would be saved to a database Then once a new email had been found the users would receive an email notification will tells them to log back into the site to see it. My questions are: Would this be possible? What would be a good language to use(generally I like php, python and java) Are there any frameworks which would help do this? How would I connect the users email account to allow access to their emails(do I need a mail server?) Any advice? Thank you! If you need more information please let me know.

• What is considered third party code?

  - by Songo

  Inspired by this question Using third-party libraries - always use a wrapper? I wanted to know what people actually consider as third-party libraries. Example from PHP: If I'm building an application using Zend framework, should I treat Zend framework libraries as third party code? Example from C#: If I'm building a desktop application, should I treat all .Net classes as third party code? Example from Java: Should I treat all libraries in the JDK as third party libraries? Some people say that if a library is stable and won't change often then one doesn't need to wrap it. However I fail to see how one would test a class that depends on a third party code without wrapping it.

• What language yields most rapid development of a SOAP client application

  - by mathematician1975

  I have written a SOAP client application. It started off as Perl but I needed it to have proper multithreaded capabilities, so I rewrote it in C++ which was a horrendous experience and the development time was many many times more than that of the Perl bot. I need to implement a new SOAP client and I was wondering what peoples opinions were about choice of language with regards to fastest development time. C++ is clearly not well suited to web services type programming so there is no way I am going to write in C++ again.

• How can I decrease my C# learning curve? [closed]

  - by MSU

  I have been learning programming, mostly C# and .net stuff. And I have target to become a fulltime .NET developer. But I am feeling that learning Graph is very slow, I have been learning C# programming, doing some coding everyday, but how I can learn very fast and increase my skills rapidly? I know there should be a balance of coding and reading, as without reading I can't code and without coding I can't increase my skills. SO, I am requesting here suggesting from experts on how I bring more pace to my learning curve? I intend to give 4-6 hours daily for this and on weekends 10+ hours.

• Should code comments have scope?

  - by Rig Veda

  I am asking this because I have seen places where, whoever coded initially had provided proper comments, but later on modifications were made to the code but the comments were left untouched. I remember reading somewhere " Don't get suckered in by the comments, debug only code". So is it a good/ relevant/ practical idea that tells the scope of the comments so as to prompt the developer for editing the comment. Your thoughts.

• If I were to claim I knew C++, what libraries would you expect me to know?

  - by Peter Smith

  I'm unsure as to the definition of knowing a programming language, so I'm picking C++ as an example. How much does it take to someone to be qualified as knowing C++? Should they just know the basic syntax? Template and generic-programming? Compiler flags and their purposes (Wall, the difference between O1, O2 and O3)? STL? Garbage collection strategies? Boost? Common libraries like zlib, curl, and libxml2?

• What programming language should I learn for fun?

  - by Bo Milanovich

  Disclaimer: I'm not a programmer, but I do like coding from time to time. This is strictly for fun, nothing else. I'm an economist :) I learned Delphi in the past (7 years ago, forgot 99% of it), BASIC (10 years ago). I now know a bit of PHP. So I want to learn a programming language just so I can kill some time, but it'd be awesome if it would be useful as well. I've narrowed down choices to the following: Python (heard it was easy yet useful, Google's appengine runs on python) Java (awesome because cross-platform and very popular, also I'm an Android fan so I might even develop some apps) Continue learning PHP? (awesome language, I'm a web developer somewhat so it may be useful) Something else? Thanks!

• Mythbusters- Programming/hacking myths [closed]

  - by stephen776

  Hey guys. I am a big fan of the Discovery show Mythbusters, as Im sure some of you are as well. I have always wanted them to do an episode on programming/hacking. They get a lot of their show ideas from fans so I though we could compile a list of possible myths to bust. Lets hear your ideas! (sorry if this is not appropriate, close if necessary) Edit: I am not necessarily looking for subjective "This is what I want to see" answers. I am talking more along the lines of interesting computer/programming/hacking stories that would appeal to a general audience. I do not expect them to do a show on "Whats faster i++ or i + 1".

• What are QUICK interview questions for the Microsoft stack development jobs?

  - by Dubmun

  I'm looking for your best "quick answer" technical interview questions. We are a 100% Microsoft shop and do the majority of our development on the ASP.NET web stack in C# and have a custom SOA framework also written in C#. We use a combination of Web Forms, MVC, Web Services, WCF, Entity Framework, SQL Server, TSQL, jQuery, LINQ, and TFS in a SCRUM environment. We are currently on .NET 3.5 with a very near transition to .NET 4.0. Our interviewing process includes a 55 minute interview with two technical people (usually an architect and a senior developer). The two interviewers have to share the time for questions. That isn't enough time for very many true programming problems so I'm looking for more good questions that have quick, yet meaningful, answers. We are mainly interviewing for Senior Dev positions right now but may interview for some Juniors in the future. Please help?

• Trying not to get ahead of myself but it is hard!

  - by Andrew

  Well I made a 5 year plan for myself (11years-16years) I am pretty good at Java, HTML, and PHP. I have already done some end projects: Small Java Platform Game A Small Polynomial Solver A Small Image Sharing Site A Chess Website: chesslounge.net I am currently doing some Android Development and so far I have made a program that Vibrates, Blinks the Light, or Creates a custom status message based on the user input. And a program that rotates a pyramid with a texture. My question is: Should I stick to what I am doing or Learn something a little new? I am itching to do C++, but what is your advice?

• Different ways of solving problems in code.

  - by Erin

  I now program in C# for a living but before that I programmed in python for 5 years. I have found that I write C# very differently than most examples I see on the web. Rather then writing things like: foreach (string bar in foo) { //bar has something doen to it here } I write code that looks like this. foo.ForEach( c => c.someActionhere() ) Or var result = foo.Select( c => { //Some code here to transform the item. }).ToList(); I think my using code like above came from my love of map and reduce in python - while not exactly the same thing, the concepts are close. Now it's time for my question. What concepts do you take and move with you from language to language; that allow you to solve a problem in a way that is not the normal accepted solution in that language?

• Is it OK to use dynamic typing to reduce the amount of variables in scope?

  - by missingno

  Often, when I am initializing something I have to use a temporary variable, for example: file_str = "path/to/file" file_file = open(file) or regexp_parts = ['foo', 'bar'] regexp = new RegExp( regexp_parts.join('|') ) However, I like to reduce the scope my variables to the smallest scope possible so there is less places where they can be (mis-)used. For example, I try to use for(var i ...) in C++ so the loop variable is confined to the loop body. In these initialization cases, if I am using a dynamic language, I am then often tempted to reuse the same variable in order to prevent the initial (and now useless) value from being used latter in the function. file = "path/to/file" file = open(file) regexp = ['...', '...'] regexp = new RegExp( regexp.join('|') ) The idea is that by reducing the number of variables in scope I reduce the chances to misuse them. However this sometimes makes the variable names look a little weird, as in the first example, where "file" refers to a "filename". I think perhaps this would be a non issue if I could use non-nested scopes begin scope1 filename = ... begin scope2 file = open(filename) end scope1 //use file here //can't use filename on accident end scope2 but I can't think of any programming language that supports this. What rules of thumb should I use in this situation? When is it best to reuse the variable? When is it best to create an extra variable? What other ways do we solve this scope problem?

• How does a "Variables introduce state"?

  - by kunj2aan

  I was reading the "C++ Coding Standards" and this line was there: Variables introduce state, and you should have to deal with as little state as possible, with lifetimes as short as possible. Doesn't anything that mutates eventually manipulate state? What does "you should have to deal with little state as possible" mean? In an impure language such as C++, isn't state management really what you are doing? And what are other ways to "deal with as little state as possible" other than limiting variable lifetime?

• What syntax element do you hate most in a programming language you use frequently?

  - by Timwi

  No matter how much you love a programming language, there are always a few details in it that aren’t quite as nice as they could be. In this question, I would like to specifically focus on syntax elements. In a programming language that you use frequently (perhaps your favourite programming language, or perhaps the one you are forced to use at work), which syntax element do you find most unreadable, unclear, inconvenient or unpleasant?

• Benefits of classic OOP over Go-like language

  - by tylerl

  I've been thinking a lot about language design and what elements would be necessary for an "ideal" programming language, and studying Google's Go has led me to question a lot of otherwise common knowledge. Specifically, Go seems to have all of the interesting benefits from object oriented programming without actually having any of the structure of an object oriented language. There are no classes, only structures; there is no class/structure inheritance -- only structure embedding. There aren't any hierarchies, no parent classes, no explicit interface implementations. Instead, type casting rules are based on a loose system similar to duck-typing, such that if a struct implements the necessary elements of a "Reader" or a "Request" or an "Encoding", then you can cast it and use it as one. Does such a system obsolete the concept of OOP? Or is there something about OOP as implemented in C++ and Java and C# that is inherently more capable, more maintainable, somehow more powerful that you have to give up when moving to a language like Go? What benefit do you have to give up to gain the simplicity that this new paradigm represents?

• Which programming language could I use for Natural Language Processing to extract clinical words?

  - by MACEE

  I am going to do entity extraction (like Named Entity Recognition) from clinical free text (unstructured raw text such as discharge summaries) and these entities could be any medical problem, medical tests or treatments. I am going to use one of i2b2 datasets (https://www.i2b2.org/) if case you are familiar with that. I am new to the NLP(Natural Language Processing) field and I need a programming language to support NLP tasks and also easily connect to the available libraries of machine learning algorithms like CRF. I don't know much java and I heard about Python, Perl and Scala but I am not sure which one would be the best option for this task?

• What to use C++ for?

  - by futlib

  I really love C++. However, I'm struggling to find good uses for it lately. It is still the language to use if you're building huge systems with huge performance requirements. Like backend/infrastructure code at Google and Facebook, or high-end games. But I don't get to do stuff like that. It's also a good choice for code that runs close to the hardware. I'd like to do more low-level stuff, but it isn't part of my job, and I can't think of useful private projects that would involve that. Traditionally, C++ was also a good choice for rich client applications, but those are mostly written in C# and Obj-C lately - and aren't really that important anymore, with everything being a web app. Or a mobile app, which are mostly written in Obj-C and Java. And of course, web-based desktop and mobile apps are quite prominent, too. At my job, I work mostly on web applications, using Java, JavaScript and Groovy. Java is a good/popular choice for non-Google-scale backends, Groovy (or Python, or Ruby or Node.js) is pretty good for the server-side of web apps and JavaScript is the only real choice for the client-side. Even the little games I'm writing in my spare time are lately mostly written in JavaScript, so they can run in the browser. So what would you suggest I could use C++ for? I'm aware that this question is very similar. However, I don't want to learn C++, I was a professional C++ programmer for years. I want to keep doing it and find good new use cases for it. I know that I can use C++ for web apps/games. I could even compile C++ to JavaScript with Emscripten. However, it doesn't seem like a good idea. I'm looking for something C++ is really good at to stay competent in the language. If your answer is: Just give up and forget C++, you'll probably never need it again, so be it.
