• Why does the use of interface-based programming appear to be limited to behaviour?

  - by Carnotaurus

  I have been doing a little thinking about inheritance vs. realization vs. composition. I am not about to post the whole detail here. So I was wondering, when are not talking about supporting unit testing: Why does interface-based programming seem to focus upon the grouping of common behaviour, e.g., IPettable (for an animal), IEditable (for a user control), ISubmitable (for a form), etc. Why does the use of interface-based programming appear to be limited to behaviour when we could pragmatically group not so much on behaviour but on commonsense physical similarities which could have nothing to do with behaviour? It is not that there is some limiting feature within OOP; so how come?

• Distributed cache and improvement

  - by philipl

  Have this question from interview: Web Service function given x static HashMap map (singleton created) if (!map.containsKey(x)) { perform some function to retrieve result y map.put(x, y); } return y; The interviewer asked general question such as what is wrong with this distributed cache implementation. Then asked how to improve on it, due to distributed servers will have different cached key pairs in the map. There are simple mistakes to be pointed out about synchronization and key object, but what really startled me was that this guy thinks that moving to database implementation solves the problem that different servers will have different map content, i.e., the situation when value x is not on server A but on server B, therefore redundant data has to be retrieved in server A. Does his thinking make any sense? (As I understand this is the basic cons for distributed cache against database model, seems he does not understand it at all) What is the typical solution for the cache growth issue (weak reference?) and sync issue (do not know which server has the key already cached - use load balancing)? Thanks

• Where would you start if you were trying to solve this PDF classification problem?

  - by burtonic

  We are crawling and downloading lots of companies' PDFs and trying to pick out the ones that are Annual Reports. Such reports can be downloaded from most companies' investor-relations pages. The PDFs are scanned and the database is populated with, among other things, the: Title Contents (full text) Page count Word count Orientation First line Using this data we are checking for the obvious phrases such as: Annual report Financial statement Quarterly report Interim report Then recording the frequency of these phrases and others. So far we have around 350,000 PDFs to scan and a training set of 4,000 documents that have been manually classified as either a report or not. We are experimenting with a number of different approaches including Bayesian classifiers and weighting the different factors available. We are building the classifier in Ruby. My question is: if you were thinking about this problem, where would you start?

• MinGw Multiple Definitions

  - by makuto

  I'm trying to get the MinGw C++ compiler set up so I can compile my code for Windows computers and I'm having troubles. I originally installed minGw32 but then found that mingw-w64 was a better fit for me, so I uninstalled minGw32 and installed mingw-w64. The problem is that when I try to compile a simple hello world application I get Multiple Definition errors (which are not from my code). I'm thinking it has something to do with the removal of w32 and the installation of w64 without a clean directory. How do/should I clean the necessary folders & get rid of those multiple definitions.

• SSH refusing connection after changing default port

  - by wm90

  currently I'm handling 2 server (A and B). In server A I installed Ubuntu 12.10. I changed the SSH port into 1198 and it works fine. In server B it has been installed with Ubuntu 11.04. I tried to change the port number into 1198 as well but it refused the connection when I tried to connect again using Putty. I change the SSH configuration on /etc/ssh/sshd_config and I did restart the SSH using sudo service ssh restart. I was thinking its because of firewall allowed port but the firewall shows inactive when I run sudo ufw status. Any idea why this can happened?

• Can all code be represented as a series of Map / Filter / Reduce operations?

  - by Mongus Pong

  I have recently been refactoring large chunks of code and replacing them with Linq queries. Removing the language bias - Linq is essentially a set of Map / Filter and Reduce operations that operate on a sequence of data. This got me thinking, how far would I theoretically be able to take this. Would I be able to rewrite the whole code base into a series (or even a single) of Map / Filter and Reduce operations. Unfortunately I get paid to do useful stuff, so I haven't been able to experiment much further, but I can't think of any code structure that couldn't be re structured as such. Side effected code can be dealt with via monads.. Even output is essentially mapping memory addresses to screen addresses. Is there anything that couldn't be (theoretically) rewritten as a Linq query?

• Move site to new domain divided by language across subdomains

  - by mark

  I managed to find a nice domain for a fairly fledgling site of mine that actually hasn't been parked by scumbag squatters. Given the upcoming move I'm thinking I'd take the opportunity to split the content across subdomains according to language, much like wikipedia for example: current: www.old-domain.com/en/subject # English www.old-domain.com/subjecto # Spanish (default so not locale in url) proposed en.new-domain.com/subject es.new-domain.com/subjecto The advantage of doing this is a fairly competitive keyword such that I may wish to put a copy of my application on a Spanish slice in order to gain a few serp's. Also pure vanity. Google's webmaster tools allows me to move to the new domain and I can add the root domain and the subdomains but forward to only one. I'll 301 from the old domain appropriately but is there anything I should know about webmaster tools in this respect where effectively I'm moving to two addresses? (Feel free to dissuade me from doing this if it's a bad idea in comments.) I've now asked this same question on google's forums.

• Studying Quantum Computing?

  - by The_Neo

  Hi I am a computer science student currently on an internship and I have been thinking more and more about looking into working for a company / places that is developing quantum computers/ing when I graduate. Here is my problem, I have a pretty solid grasp of mathematics involved in Comp Sci and enjoy learning about more Comp Sci theory but in doing some minor research about Quantum Computing it seems to me to be more about hardware and I have always leant more to the software side of things. I haven't studied any physics since high school so I am wondering if I would be suitable to work in such a field with a Comp Sci degree, is it a field more aimed at physicists?

• How do you know when to split an object method into 2 or more other methods?

  - by blacktie24

  Hi, I know this is a very basic question, but I sometimes find myself struggling to figure out when to split a single object method into multiple methods. For example, I am trying to set up an ACL using Zend_Acl and Zend_Auth, as shown in this tutorial: http://devzone.zend.com/article/1665. However, I am wondering if the My_Plugin_Auth::preDispatch() method should invoke calls to a method called authenticate() and a method called authorize(), instead of having everything lumped in under preDispatch(). I was thinking that this would make the code more readable and encapsulate the logic into its smaller parts, but i'm not sure if this is reason enough.

• Is it necessary to understand what's happening at the hardware level to be a good programmer?

  - by bev

  I'm a self-taught programmer, just in case this question is answered in CS 101. I've learned and used lots of languages, mostly for my own personal use, but occasionally for professional stuff. It seems that I'm always running into the same wall when I run into trouble programming. For example, I just asked a question on another forum about how to handle a pointer-to-array that was returned by a function. Initially I'm thinking that I simply don't know the proper technique that the designers of C++ set up to handle the situation. But from the answers and discussions that follow I see that I don't really get what happens when something is 'returned'. How deep a level of understanding of the programming process must a good programmer achieve?

• How to organize my 1000s of PDF?

  - by mmb

  I have a huge collection of PDF. Mostly it consists of research papers, of self-created documents but also of scanned documents. Right now I drop them all in one folder and give them precise names with tags in the filename. But even that gets impractical, so I am looking for a PDF library management application. I am thinking of something like Yep for Mac, with the following features: PDF cover browsing (with large preview, larger than Nautilus allows) tagging of PDF (data should be readable cross-platform) possibility to share across network (thus rather flat files than database) if possible: cross-platform Mendeley seemed to be a good choice, but I am not only having academic papers and don't want to fill it all metadata that is required there. The only alternative I could find thus far is Shoka, but the features are limited and developments seems to have stopped already.

• Advice on what to learn? [closed]

  - by ICTech

  Currently I work as a .NET C# programmer, quite fresh faced at that (only been working professionally for 8 months) I'm enjoying what I'm doing, but I'm now thinking ahead for other languages to learn. I've heard from quite a few seasoned developers that they reckon it's worth getting in to HTML5. Before I asked this question I read a few of the other questions similar to this, but most were dated back a few years. I'm wondering what your advice would be to an aspiring programmer, what I should avoid going for (i.e. as I understand it Flash is essentially going to be phased out due to HTML5) I was looking in to WPF and the more updated .NET technologies, but someone advised me that WPF stuff will probably be redundant in the future. Thanks for your advice and opinions :)

• Is there a phrase or word to describe an algorithim or program is complete in that given any value for its arguments there is a defined outcome?

  - by Mrk Mnl

  Is there a phrase or word to describe an algorithim or programme is complete in that given any value for its arguments there is a defined outcome? i.e. all the ramifications have been considered whatever the context? A simple example would be the below function: function returns string get_item_type(int type_no) { if(type_no < 10) return "hockey stick" else if (type_no < 20) return "bulldozer" else return "unknown" } (excuse the dismal pseudo code) No matter what number is supplied all possibiblites are catered for. My question is: is there a word to fill the blank here: "get_item_type() is ______ complete" ? (The answer is not Turing Complete - that is something quite different - but I annoyingly always think of something as "Turing Complete" when I am thinking of the above).

• Application versioning

  - by Mathew

  Haven't find similar issue so sorry if thats a duplicate. I'm about to start a migration of an already existing project from one web container version to the another. Currently, the application version is 2.2.5. Business requirement is to deliver a 3.0 version by the end of the year. Additional constraint is to release a working, stable version by the end of Q3. We are about to work in 2-weeks sprints and I'm wondering how can I approach the problem? I was thinking about releasing 2.3 by the end of Q2, then immediately promoting it as 3.0-a1, work on alphas (3.0-a2, 3.0-a3, ...) till the end of Q3, to start with 3.0-b1 in the early Q4 and finally release 3.0 around December. I don't feel comfortable saying that the application is already in 3.0 state in July, but I can't see other options. If you find some book chapters/blogs or your personal experience interesting please share your opinion.

• What is the correct way to use glTexCoordPointer?

  - by RubyKing

  I'm trying to work out how to use this function glTexCoordPointer. The man page states that I must set a pointer to the first element of the array that uses the texture cordinate. Here is my array: static const GLfloat GUIVertices[] = { //FIRST QUAD 1.0f, 1.0f, 0.0f, 1.0f, 1.0f, 0.0f, -1.0f, 1.0f, 0.0f, 1.0f, 0.0f, 0.0f, -1.0f, 0.94f, 0.0f, 1.0f, 0.0f, 1.0f, 1.0f, 0.94f, 0.0f, 1.0f, 1.0f, 1.0f, //2ND QUAD // x y z w X Y 1.0f, -1.0f, 0.0f, 1.0f, 1.0f, 0.0f, -1.0f, -1.0f, 0.0f, 1.0f, 0.0f, 0.0f, -1.0f, -0.94f, 0.0f, 1.0f, 0.0f, 1.0f, 1.0f, -0.94f, 0.0f, 1.0f, 1.0f, 1.0, }; But how do I set the pointer correctly for the fifth element on the 2nd quad first row? I was thinking something like this: glTexCoordPointer(1, GL_FLOAT, 6, reinterpret_cast<const GLvoid *>(29 * sizeof(float)));

• Web App for storing and organize programming information?

  - by Fabzter

  So, I've found myself, after several years of coding (I consider myself a coder, rather than a programmer) full of links and loose snippets and coding tips, all dispersed across the web. In such way it is barely usable, even when every bit is important or interesting. I thought of simply storing the links in delicious or something alike, but it's not really the links I want to keep, I just need the succinth info. So I was thinking to use some web app, something like a wiki, maybe much more simple, so I could access it though my mobile if I need it. I could code it, but as I stated it before, I'm more of a code monkey, and I'm sure my solution would be far from decent... Can anyone give me recommendations on this?

• CMSs & ERPs for hospital management system

  - by Akshey

  Hi, What are the best free CMSs or CMS plugins or ERPs or any other free tools available for developing a hospital management system? I want to develop it for a children's hospital run by my father. The hospital is small with two doctors. Currently, everything is done manually on paper. The main entities who will be using the system are: Receptionist, the two doctors, chemist and the medical laboratorist. They will use it majorly for keeping the records of the patient. The patients would not be interacting with the system directly. The system needs to be user friendly and should be easy to learn. I was thinking to develop such a system using a CMS or an ERP or any other free tool. I have used wordpress/drupal in past but never used an ERP. Can you please guide me to make such a system using free, and preferably open source, tools? Thanks, Akshey

• Best Practice to return responses from service

  - by A9S6

  I am writing a SOAP based ASP.NET Web Service having a number of methods to deal with Client objects. e.g: int AddClient(Client c) = returns Client ID when successful List GetClients() Client GetClientInfo(int clientId) In the above methods, the return value/object for each method corresponds to the "all good" scenario i.e. A client Id will be returned if AddClient was successful or a List< of Client objects will be returned by GetClients. But what if an error occurs, how do I convey the error message to the caller? I was thinking of having a Response class: Response { StatusCode, StatusMessage, Details } where Details will hold the actual response but in that case the caller will have to cast the response every time. What are your views on the above? Is there a better solution? ---------- UPDATED ----------- Is there something new in WCF for the above? What difference will it make If I change the ASP.NET Web Service to a WCF Service?

• I will be at NNUG Kristiansand tonight

  - by Sahil Malik

  SharePoint 2010 Training: more information Greetings! I will be speaking at NNUG Kristiansand tonight (sorry for the very short notice). So I was thinking what should I demo tonight?Hmm!!!Instead of using any slides or such material, what I thought would be a tonne of fun, would be to develop a service bus based application running in Azure. This will be a good opportunity to code and talk, and run into some snafus and show off some VS2012 improvements/annoyances. At the end of an apprx. 1 hour talk, I hope to have an application ready that you can run yourself by the end of the evening. hehe :) .. now that’s cool isn’t it? :) .. Time permitting I will even tie SP2013 + ADFSv2 + Claims into it, just to be cool. Hope to see you there!

• Is the UX affected negatively by fully cacheable pages?

  - by ChocoDeveloper

  I want to have fully cacheable pages in my websites, but one cannot do that if they contain user-specific data, like the userbar or things in the UI that can change depending on the permissions the user has. So I was thinking whether it was possible to pull everything that is user-specific via ajax, and update the UI accordingly. But I'm worried that this might be annoying for the user, and also it might be difficult to develop. What do you think? Is there a pattern or something I can follow to deal with this?

• Best container to store this information

  - by user2368481

  I'm trying to write a smallish system as a homework excercise, I don't have much experience with containers and I'm not sure the best way of storing this data would be: Incident Records object holds instants of Incident Report. Report is a superclass which has 3 subclasses, Police, Fire or Medical. Record must must record which of these types apply, and which response teams are to be involved. So Record has to keep track of the Report objects, the type of the report (Police, Fire or Medical) and the teams involved in the reports. I was initially thinking of an array but that wouldn't be sufficient to hold all the info. Record<>---------Report<|----------Police, Fire or Medical

• My data vanished after copying to E drive

  - by pnp

  Of late I had been thinking of having a fresh install of Ubuntu. So I cut-pasted all my required files and folders in my E drive. Then I decided to not to have a fresh install and just let it be. Later, when I booted up in Windows (dual-boot with 12.04 and Windows 7), I found that the files and folders I had cut-pasted from my home account in Ubuntu are just not there. What is even more surprising is that now, when I am back on Ubuntu, those files and folders that should have been there in my E drive are also not there. Is it an Ubuntu issue or a hard drive issue?

• Attempting to install Ubuntu 11.10 along side Windows 7 Professional 64bit. Installer doesn't recognize an operating system present

  System Details: Asus Sabertooth 990FX motherboard AMD FX-8120 CPU 16 GB DDR3 1600 Corsair Vengance RAM (4x4) EVGA Nvidia GTX-560Ti video card 2x Dvd/cd rw dirves 1 Bluray RW drive 1 Orico USB 3.0 & eSata panel 1 Sabrent floppy bay card reader w/USB 2.0 port 760W pc power & cooling PS OCZ agility 120GB SSD (Windows 7 Professional 64bit installed in an approx 80gb partition, NTFS. There is also a "System Reserved" partition shown in disk management at 100mb in size, also NTFS) That leaves about 32GB usable free, un-partitioned space in which I hoped to install Ubuntu. However when I run the Ubuntu 11.10 AMD64 installer, it doesn't show there is even an operating system installed. It just shows the entire drive as free-unpartitioned space. Just not sure what to do here. I was thinking about using the Wubi installer, but i don't know about that. Is the performance reduction pretty drastic? Thanks,

• Where can I find crash course in Java eclipse in Vancouver?

  - by user3604

  I am not satisfied with what I learned in Java 101 in University. I feel like, lot of time is spent on trying to figure out how to write something in Java properly. I feel like, my lack of knowledge of Java and eclipse is slowing me down. I would like to pay for a detailed and intensive course in Java & Eclipse. I can read a book and read tutorials, but it seems harder to discipline myself. Where can I find such crash courses outside of university courses? I find lot of CS courses just show tip of the iceberg and not too much focused on actual application. I want to learn the latest industry skills and etc. I live in BC, Canada. I am thinking of BCIT, but not sure what they offer.
