• Dynamic Programming resources in C?

  - by EsotericMe

  Hi everyone, I'll be writing the online Google test tomorrow as a fresher. Apparently, they definitely ask one problem on Dynamic Programming? Does anyone know of a good resource for collection of DP problems in C along with solutions? I know what DP is & have used it on an occasion or twice. However I feel to crack a DP problem in test, prior practice of typical problems will make it easier to approach. Any good resources or problem sets with solutions in C will be highly appreciated. Thanks.

• Web Designer looking to learn back-end programming...

  - by Tabetha Moe

  Hello, my name is Tabetha and I have a question... I am a web designer, but I always find that while designing the layout and coding the design I come up with great ideas for websites. I would like to know where I need to start in order to learn back-end programming not only for the knowledge, but also for the challenge of it. I have searched online but can't seem to find the information I am looking for. If anyone can give me a simple, straight-forward "this is what language you need to learn" answer, or perhaps guide me in the right direction I would appreciate it ten-fold. I am a complete noob when it comes to this, so even the most basic information is probably a pearl of wisdom for me. :)

• Programming message boards [closed]

  - by Slayer0248

  I'm not at all meaning to seem rude or arrogant or something like that to everyone here, but why must we all be so mean when trying to answer each other's questions? I mean people have the right to pick up a skill such as programming at any point in time. It's not like we aren't encouraged to ask each other for help, but alot of people who are doing the answering seem to generally say "this is simple. why aren't you getting this?". I mean some of it may be, but isn't it really kind of an indicator that we should make the documentations for these things a little more extensive?

• Choosing an alternative ( visual basic) high level programming language

  - by user370244

  I used to be visual basic 6 programmer, i was pleased with visual basic : it is high level language that do stuff fast,easy to learn, easy to do stuff in,you can drag and drop stuff to the form and write your code,it is simply amazing.however microsoft buried VB6 and pointed us to VB.NET which is so different that it is not the old VB anymore.I didn't like what microsoft did and would like to look somewhere AWAY from microsoft and from any other proprietary language . I would like to look into a similar language that is easy,cross platform (windows / Linux), object oriented, visual design, non proprietary and compile (for some guarding against reverse engineering). i am freelancer so the choice is entirely mine,i don't care about performance of programs, the time taken to develop a given programs is much more important. desktop / database / GUI /networking programming is what i am looking for. so any such language offered by our open source community ? thank you so much

• Is a functional spec a part of the System requirement spec?

  - by user970696

  I wonder, sources like wikipedia or templates I found shows that Functional spec is a part of System requirement documents. I always thought that SRD is just overall decsription of the system, with all functional and non functional requirements. Yet I thought that Functional spec is more detailed and it is a separate document, while SRD is high level customer-created description (how is this one called then?) Could anyone help to make this clear for me?

• Haskell vs Erlang for web services

  - by Zachary K

  I am looking to start an experimental project using a functional language and am trying to decide beween Erlang and Haskell, and both have some points that I really like. I like Haskell's strong type system and purity. I have a feeling it will make it easier to write really reliable code. And I think that the power of haskell will make some of what I want to do much easier. On the minus side I get the feeling that some of the Frameworks for doing web stuff on Haskell such as Yesod are not as advanced as their Erlang counter parts. I rather like the Erlang approach to threads and to fault tollerence. I have a feeling that the scalability of Erlang could be a major plus. Which leeds to to my question, what has people's exerience been in implementing web application backends in both Haskell and Erlang. Are there packages for Haskell to provide some of the lightweight threads and actors that one has in Erlang?

• Code Reuse and Abstraction in FP vs OOP

  - by Electric Coffee

  I've been told that code reuse and abstraction in OOP is far more difficult to do than it is in FP, and that all the claims that have been made about Object Orientedness (for lack of a better term) being great at reusing code have been flat out lies So I was wondering if anyone here could tell me why that is, and perhaps show me some code to back up these claims, I'm not saying I don't believe you Functional programmers, it's just that I've been "indoctrinated" to think Object Orientedly, and thus can't (yet) think Functionally enough to see it myself To quote Jimmy Hoffa (from an answer to one of my previous questions): The cake is a lie, code reuse in OO is far more difficult than in FP. For all that OO has claimed code reuse over the years, I have seen it follow through a minimum of times. (feel free to just say I must be doing it wrong, I'm comfortable with how well I write OO code having had to design and maintain OO systems for years, I know the quality of my own results) That quote is the basis of my question, I want to see if there's anything to the claim or not

• Writing use cases for XML mapping scenarios between two different systems

  - by deepak_prn

  I am having some trouble writing use cases for XML mapping after a certain trigger invoked by the system. For example, one of the scenarios goes: the store cashier sells an item, the transaction data is sent to Data management system. Now, I am writing a functional design for the scenario which deals with mapping XML fields between our system and the data management system. Question : I was wondering if some one had to deal with writing use cases or extension use cases for mapping XML fields between two systems? (There is no XSLT involved) and if you used a table to represent the fields mapping (example is below) or any other visualization tool which does not break the bank ? I searched many questions on SO and here but nothing came close to my requirement.

• Are there programming languages that allow you to do set arithmetic on types?

  - by Will Brown

  Out of curiosity, are there languages that allow you to do set arithmetic on types to create new types? Something like: interface A { void a(); void b(); } interface B { void b(); void c(); } interface C = A & B; // has b() interface D = A | B; // has a(), b() and c() interface E = (A & B) ^ B; // has c() I know that in some languages these ideas can be expressed (i.e., Java has List<Comparable & Serializable> for the union of the interfaces) but I've never heard of a language that supports type arithmetic. Thanks!

• What is the correlation between programming language and experience/skills of their users?

  - by Petr Pudlák

  I'm sure there is such a correlation, because experience and skill leads good programmers to picking languages that are better for them, in which they're more productive, and working in a language forms how programmers think and influences their methods and skills. Is there any research or some statistical data of this phenomenon? Perhaps this is not a purely academic question. For example, if someone is starting a new project, it could be worth considering a language (among other criteria of course) for which there is a higher chance of finding or attracting experienced programmers. Update: Please don't fixate on the last paragraph. It's not my intention to choose a language based on this criterion, and I know there are other far more important ones. My interested is mostly academic. It comes from the (subjective) observation and I wonder if someone has researched it a bit. Also, I'm talking about a correlation, not about a rule. Sure there are both great and terrible programmers in every language. Just that in general it seems to me there is a correlation.

• Why has there been no serious research in statistical programming languages for 25 years?

  - by Robert

  The two main statistical languages today are S (in the form of R) and SAS, which today pretty much have the form they had 25 years ago. Whatever usability problems or worker productivity problems they had then, they still have today. I'm a data language designer, and I look at, largely, four aspects: Usability (learning curve & readability - here Python scores high) Productivity (how long it takes to finish your work) Flexibility (SAS and R don't have problems here, but a macro library will) Reliability (in the QA/reproducibility sense, usually a PL does better than a GUI here) By the way, I have a language that can produce complex statistical tables much faster than SAS (like 25 lines of code instead of several hundred lines of code). And I'm going to produce a language for data cleaning that will be great for usability (it'll be my third).

• Is there a programming language with not a tree but tags idea behind OOP?

  - by kolupaev

  I'm thinking about tree structures, and I feel that I don't like them. It's like when you have a shop, then you try to put all products to tree-like catalog, and then you need to place one product to multiple categories, now you have multiple routing, bla-bla. I don't feel like everything in the world could be put to a tree. Instead, I like idea of tags. I would like to store everything with tags. With tags I could do much more. I can even simulate trees if I want. I want to have tag-based filesystem! But hey - modern OOP paradigm with inheritance is based on tree. I want to see how it is when you don't have such basement. Closest thing I found is mixins in some languages. Do you know what else is also about this ideas?

• How to choose the right web development language for my app without much programming experience?

  - by twinbornJoint

  I have my own idea for a web application, and I am not a programmer. The application will work similar to Facebook and Twitter, profiles and feeds. I have learned some computer science theory, all the way up to OOP, but have no practical experience. Without any experience, is there a way I can evaluate the different language and platform choices available to me? What kind of things should I be looking at? Ease of setup? How many followers it has? How can I evaluate whether a language will have the capabilities I need?

• Should tests be in the same ruby file or in separeted ruby files?

  - by Junior Mayhé

  While using Selenium and Ruby to do some functional tests, I am worried with the performance. So is it better to add all test methods in the same ruby file, or I should put each one in separated code files? Below a sample with all tests in the same file: # encoding: utf-8 require "selenium-webdriver" require "test/unit" class Tests < Test::Unit::TestCase def setup @driver = Selenium::WebDriver.for :firefox @base_url = "http://mysite" @driver.manage.timeouts.implicit_wait = 30 @verification_errors = [] @wait = Selenium::WebDriver::Wait.new :timeout => 10 end def teardown @driver.quit assert_equal [], @verification_errors end def element_present?(how, what) @driver.find_element(how, what) true rescue Selenium::WebDriver::Error::NoSuchElementError false end def verify(&blk) yield rescue Test::Unit::AssertionFailedError => ex @verification_errors << ex end def test_1 @driver.get(@base_url + "/") # a huge test here end def test_2 @driver.get(@base_url + "/") # a huge test here end def test_3 @driver.get(@base_url + "/") # a huge test here end def test_4 @driver.get(@base_url + "/") # a huge test here end def test_5 @driver.get(@base_url + "/") # a huge test here end end

• What is the best way to track / record the current programming project you work on? [duplicate]

  - by user2424160

  This question already has an answer here: Methodology for Documenting Existing Code Base 6 answers When do you start documenting the code? 13 answers Where should a programmer explain the extended logic behind the code? 5 answers I have been in this problem for long time and I want to know how it's done in real / big companies project? Suppose I have the project to build a website. Now I divide the project into sub tasks and do it. But you know that suppose I have task1 in hand like export the page to pdf. Now I spend 3 days to do that , came across various problems, many Stack Overflow questions and in the end I solve it. Now 4 months after someone told me that there is some error in the code. Now by that I completely forgot about (60%) of how I did it and why I do this way. I document the code but I can't write the whole story of that in the code. Then I have to spend much time on code to find what was the problem so that I added this line etc. I want to know that is there any way that i can log steps in completing the project. So that I can see how I end up with code, what errors I got, what questions I asked on SO and etc. How people do it in real time? Which software to use? I know in our project management software called JIRA we have tasks but that does not cover what steps I took to solve that tasks. What is the best way so that when I look back at my 2 year old project, I know how I solve particular task?

• How to tell your boss that his programming style is really bad?

  - by Roflcoptr

  I'm a student and in my spare time I'm working for a big enterprise as Java developer. The job is good, but the problem is, my boss is writing very strange code. I don't want to complain, but some issues are in my opinion really strange. For example: he doesn't know any booleans. All boolean conditions are Strings called "YesOrNo" and then in the condition he uses if (YesOrNo == "Yes") there are a lot of very strange characters in method names and variables like é õ ô or è all loops are infinite loops in the style of for(;;). Then at the end of the loop the condition is tested and if the conditions is fulfilled break; is called. I don't now if I should tell him that I think this isn't a good practice, since he is my boss and decides how and what to do. On the other hand some of this examples are really very weird. Any hints how to cope with? And is this only me who thinks that's bad style?

• What is the Best way to learn c# programming and capability to do anything with C#?

  - by MSU

  I browsed all the answers given in Stackoverflow,i couldn't find my answer that's why i am writing this, so please don't mark this a duplicate. My case i want to get the capability of doing anything in C# from building applications to solving problems. I searched for and tried to read books. Then one of the experts said, reading books will not make any good for you, for learning you have to solve problems i.e. real world problems in C#, he gave me some sample problems, which i previously did in C++, i started doing, but the thing is that i know the internal logic of solving the problem or the algorithm to solve. But i don't know how to imepelement them using C# efficiently. so, the gap is, i can't think in C#, I know the message to passed but don't the exact way to pass it. I did a program to solve a problem, then find out there are much easier ways of doing it wherever i was doing it in tougher way. So, can you guys(C# experts) please enlighten me, what i need to get hold of the language and get the ability to code in C# proficiently?

• OOP vs Frameworks (DRY, Organisation, Readability)

  - by benhowdle89

  In terms of organisation, code-readability and DRY programming, which, between OOP and Frameworks shows more of these 3 attributes? I'm aware that inline, procedural coding is viewed by many as a thing of the past, so which is the best route to take for these two? Just to clarify what i mean by OOP and frameworks From Wikipedia: Object-oriented programming (OOP) is a programming paradigm In computer programming, a software framework is an abstraction in which common code providing generic functionality can be selectively overridden or specialized by user code, thus providing specific functionality

• What are the most common stumbling blocks when it comes to learning programming, in order of difficulty?

  - by blueberryfields

  I seem to remember that linked lists, recursion, pointers, and memory management are all good examples of stumbling blocks - places where the aspiring programmer typically ends up spending significant time trying to understand a concept before moving on and improving, and many end up giving up and not improving. I'm looking for a complete/comprehensive list of these types of stumbling blocks, in rough estimated order of difficulty to learn, with the goal of making sure that an educational program for programmers is structured to properly guide students through them Is this information available somewhere? Ideally, the difficulty to learn will be measured in some sort of objective manner (ie, % of students which consistently fail to learn the concept) What sources are most appropriate for obtaining this information?

• C++11 support for higher-order list functions

  - by Giorgio

  Most functional programming languages (e.g. Common Lisp, Scheme / Racket, Clojure, Haskell, Scala, Ocaml, SML) support some common higher-order functions on lists, such as map, filter, takeWhile, dropWhile, foldl, foldr (see e.g. Common Lisp, Scheme / Racket, Clojure side-by-side reference sheet, the Haskell, Scala, OCaml, and the SML documentation.) Does C++11 have equivalent standard methods or functions on lists? For example, consider the following Haskell snippet: let xs = [1, 2, 3, 4, 5] let ys = map (\x -> x * x) xs How can I express the second expression in modern standard C++? std::list<int> xs = ... // Initialize the list in some way. std::list<int> ys = ??? // How to translate the Haskell expression? What about the other higher-order functions mentioned above? Can they be directly expressed in C++?

• How Does The Maybe Monad Relate To The Option Type?

  - by Onorio Catenacci

  I was doing a presentation on F# and was discussing the Option type when someone in the audience asked me if the Option type is F#'s implementation of the maybe monad. I know that's not the case but I did want to ask how the two concepts are related. I mean it seems to me that an option type might be the result of the operation of a maybe monad but I'm not even sure of that. Would someone elucidate the relationship between the maybe monad and the option type in those functional languages which support it?
