  • Which Shopping Cart is better to run online grocery shop Prestrashop or nopCommerce

    - by Bigmunk
    I have been researching on open source software for an online grocery shop project. I have now narrowed by search to .NET based nopCommerce and the PHP based PrestaShop shopping carts. My plan is to acquire an open source shopping cart and hire a local developer to customize it to our local needs & as per our requirement. I'm now wondering whether I should have a developer start the whole project from scratch, or use an open source software such us PrestaShop or nopCommerce which can then be customized? Note that my store will have thousands of products and services so I want something that can handle up to 5000 products and over. Thanks for your thoughts and advice in advance.

  • How do I know when should I package my classes in Ruby?

    - by Omega
    In Ruby, I'm creating a small game development framework. Just some personal project - a very small group of friends helping. Now I am in need of handling geometric concepts. Rectangles, Circles, Polygons, Vectors, Lines, etc. So I made a class for each of these. I'm stuck deciding whether I should package such classes in a module, such as Geometry. So I'd access them like Geometry::Rectangle, or just Rectangle if I include the module. Now then, my question isn't about this specific scenario. I'd like to know, when is it suitable to package similar classes into one module in Ruby? What factors should I consider? Amount of classes? Usage frequency? Complexity?

  • How do you manage feature requests and software changes?

    - by 0A0D
    I am a Software Engineer and over the past few years I have become the de-facto software project manager simply because there isn't one. So to keep our sanity in the R&D/Engineering department, customers have become accustomed to coming to me with their requests. I have no experience in this realm so it is my first time acting as a project manager for software projects. I have managed other things but not software. So, how do you manage software projects and mark priorities? Requests come in at infrequent intervals so we very well could be working on something for someone else and then another person comes in with a "rush" job that needs working on. Is it easier to just say First Come, First Serve or is it the person with the most money?

  • SOA, Java EE and data organization

    - by jolasveinn
    At the company I work for, we're currently splitting up our monolith solution into a number of small services (SOA). Many of the services are small, so we'd like to deploy a number of these services on the same application server, JBoss 7.1 in this case. As per the SOA philosophy, the independence of each service and the teams working on them is very important. What would be the best way to organize the data? Use one schema per service Would you use one datasource per schema in the application server? Or use one datasource, prefixing all DB object names with the schema name in some transparent manner? Use a shared schema, but evading any naming collisions by requiring each service to use a distinct prefix for all DB objects Other options? Am I maybe thinking this completely wrong here? :)

  • android app unable to connect to the hsqldb server

    - by Chinta
    I am trying to connect my android app to the hsql db server. Server runs on computer-1. I can connect to the db server from local machine through java as well as Db-visualizer. I can connect to the db server from another computer(computer-2) using Db-visualizer with comouter-1 ip address. Now trying to connect from my app in Nexus 7 the same way I was connecting from computer-2. I am getting "No Suitable Driver" error.

  • What are the preferred documentation tools for the major programming languages?

    - by Dave Peck
    I'm interested in compiling a list of major programming languages and their preferred documentation toolsets. To scope this a bit: The exact structure of the answer may vary from language to language, but there appear to be two aspects common to all languages: (1) in-code syntax for documentation, and (2) documentation generators that make use of said syntax. There are also cases where generators are used independent of code. For example, tutorial-style documentation is common in the Python world and is often disconnected from underlying code. Many languages have multiple commonly-used documentation strategies and tool chains, and I'd love to capture this. Finally, there are cross-language tools like Doxygen that also have some traction and would be worth noting here. Here are some obvious target languages to start with: Python, Ruby, Java, C#, PHP, Objective-C, C/C++, Haskell, Erlang, Scala, Clojure If this question catches on, I'll try and keep this section updated with the most recent list. Thanks!

  • Information Spilling Across Object Boundaries

    - by Winston Ewert
    Many times my business objects tend to have situations where information needs to cross object boundaries too often. When doing OO, we want information to be in one object and as much as possible all code dealing with that information should be in that object. However, business rules do not follow this principle giving me trouble. As an example suppose that we have an Order which has a number of OrderItems which refers to an InventoryItem which has a price. I invoke Order.GetTotal() which sums the result of OrderItem.GetPrice() which multiples a quantity by InventoryItem.GetPrice(). So far so good. But then we find out that some items are sold with a two for one deal. We can handle this by having OrderItem.GetPrice() do something like InventoryItem.GetPrice( quantity ) and letting InventoryItem deal with this. However, then we find out that the two-for-one deal only lasts for a particular time period. This time period needs to be based on the date of the order. Now we change OrderItem.GetPrice() to be InventoryItem.GetPrice( quatity, order.GetDate() ) But then we need to support different prices depending on how long the customer has been in the system: InventoryItem.GetPrice( quantity, order.GetDate(), order.GetCustomer() ) But then it turns out that the two-for-one deals apply not just to buying multiple of the same inventory item but multiple for any item in a InventoryCategory. At this point we throw up our hands and just give the InventoryItem the order item and allow it to travel over the object reference graph via accessors to get the information its needs: InventoryItem.GetPrice( this ) TL;DR I want to have coupling in objects, but business rules often force me to access information from all over the place in order to make particular decisions. Are there good techniques for dealing with this? Do others find the same problem?

  • What do you do about content when someone asks you to build a website

    - by Jon
    I am an experienced asp.net developer and asp.net mvc and I have my own CMS that I have written but starting to think there should be another approach. When someone asks you to develop them a website how do you develop it so that they can add pictures,slideshows, content, news items, diary events. On a side note do you give them a design for the home page and inner page and thats it. I'm just thinking if they turn around and say 6 months down the line I want a jquery slideshow on the right hand side of this page how do you or CMS's handle it?

  • Mono is frequently used to say "Yes, .NET is cross-platform". How valid is that claim?

    - by Thorbjørn Ravn Andersen
    In What would you choose for your project between .NET and Java at this point in time ? I say that I would consider the "Will you always deploy to Windows?" the single most important decision to make up front in a new web project, and if the answer is "no", I would recommend Java instead of .NET. A very common counter-argument is that "If we ever want to run on Linux/OS X/Whatever, we'll just run Mono", which is a very compelling argument on the surface, but I don't agree for several reasons. OpenJDK and all the vendor supplied JVM's have passed the official Sun TCK ensuring things work correctly. I am not aware of Mono passing a Microsoft TCK. Mono trails the .NET releases. What .NET-level is currently fully supported? Does all GUI elements (WinForms?) work correctly in Mono? Businesses may not want to depend on Open Source frameworks as the official plan B. I am aware that with the new governance of Java by Oracle, the future is unsafe, but e.g. IBM provides JDK's for many platforms, including Linux. They are just not open sourced. So, under which circumstances is Mono a valid business strategy for .NET-applications?

  • Date calculation algorithm

    - by Julian Cuevas
    I'm working on a project to schedule a machine shop, basically I've got everything covered BUT date calculations, I've got a method called schedule (working on PHP here): public function schedule($start_date, $duration_in_minutes) Now my problem is, currently I'm calculating end time manually because time calculations have the following rules: During weekdays, work with business hours (7:00 AM to 5:00 PM) Work on Saturdays from 7:00 AM to 2:00 PM Ignore holidays (in Colombia we have A LOT of holidays) I already have a lookup table for holidays, I also have a Java version of this algorithm that I wrote for a previous version of the project, but that one's also manual. Is there any way to calculate an end time from a start time given duration?, my problem is that I have to consider the above rules, I'm looking for a (maybe?) math based solution, however I currently don't have the mind to devise such a solution myself. I'll be happy to provide code samples if necessary.

  • How to use correctly the comments in C/++

    - by Lucio
    I'm learning to program in C and in my stage, the best form to use correctly the comments is writing good comments from the beginning. As the comments are not just for that one understands better the code but others too, I want to know the views of all of you to reach a consensus. So what I want is that the most experienced users edit the following code as you please. (If it's unnecessary, delete it; If it's wrong, correct it; If needed, add more) Thus there'll be multiple answers with different syntax and the responses with the most votes will be taken as referring when commenting. The code to copy, paste and edit to your pleasure is: (And I remark again, just import the comments, not the code) /* This programs find 1 number in 1 file. The file is binary type and has integers in series. The number is integer type and it's entered from the keyboard. When finished the program, a poster will show the results: Saying if the number is in the file or not. */ #include <stdio.h> //FUNCTION 1 //Open file 'path' and closes it. void openf(char path[]) { int num; //Read from Keyboard a Number and it save it into 'num' var printf("Ready for read number.\n\nNumber --> "); fflush(stdin); scanf("%d",&num); //Open file 'path' in READ mode FILE *fvar; fvar=fopen(path,"rb"); //IF error happens when open file, exit of function if (fvar==NULL) { printf("ERROR while open file %s in read mode.",path); exit(1); } /*Verify the result of 'funct' function IF TRUE, 'num' it's in the file*/ if (funct(path,fvar,num)) printf("The number %d it is in the file %s.",num,path); else printf("The number %d it is not in the file %s.",num,path); fclose(fvar); } /*FUNCTION 2 It is a recursive function. Reads number by number until the file is empty or the number is found. Parameters received: 'path' -> Directory file 'fvar' -> Pointer file 'num' -> Number to compare */ int funct(char path[],FILE *fvar,int num) { int compare; //FALSE condition when the pointer reaches the end if (fread(&compare,sizeof(int),1,fvar)>0) /*TRUE condition when the number readed is iqual that 'num' ELSE will go to the function itself*/ if (compare!=num) funct(path,fvar,num); else return 1; else return 0; } int main(int argc, char **argv) { char path[30]="file.bin"; //Direction of the file to process openf(path); //Function with algorithm return 0; }

  • Company wants to write custom project management tool, rather then use third party product.

    - by Jason Evans
    At the company I work, we are really wanting to get into the agile methodology for developing software. One thing that I'm not excited about is the fact that management wants us to build a custom project management feature inside the company's Intranet. I think this is a total waste of time. There are many great third party tools available (e.g. Axosoft OnTime) that can do everything we need, and more. For how much development time it would cost us to build our own project management module, we could buy numerous licences for a third party product. One concern is that, whilst we are writing code for a client, and using our custom Intranet project management module, we find bugs in the module that need fixing ASAP. That means having to stop work on the client code to fix the Intranet. That just puts shivers down my spine. Another worry I have is lack of functionality. This custom module is going to be so basic, that it will just feel really crap to use. That might sound a bit snooty, but for goodness sake, many third party tools are so feature rich, that the idea of having to write our own tool makes feel very uneasy. In fact, I can't be bothered. What do you guys think? I'm going to raise this issue with my boss, since I feel it's such an important topic to talk about. EDIT: Thanks for the great responses, much appreciated. To summarize some of them: Money Naturally my boss does want to save money, by not forking out a few hundred £'s for licences. However, for us to write a custom tool, it will take x number of days, multiplied by approx £500, which is our costs. I don't see the business value in this. Management have mentioned that they want to sell the Intranet as a product in the future, but it's so custom to our needs (and downright basic), that in order to give it to another client, I can see us having to fork a version of the code and rebuild the majority of it anyway. So it's not like we're gaining anything there in reuse. Features Having our own custom module means not feature bloat - only the functionality we require will be in the product. My issue is that there are plenty of free, open-source project management tools out there with minimal features already. So even if cost is an issue, we could look into open-source. Again it all boils down to the fact that I don't see the point in writing a project management tool in this day and age. It's a bit like writing your own web browser - why?, what's the point? Although management are asking for this tool, just because they are, it does not mean I'm going to please them and do it just because they asked for it. If something does not make sense, then I will raise it as a concern. At the end of the day, it's the developers who write the code, it's the developers who make money for a business. Thus, as far I'm concerned, the devs have a very big role in deciding how a company should manage projects and what tools are used. "I am Spartan, argh!" :) Hmm, I've not been able to make this question a wiki for some reason, thus I'm going to have to pick an answer to accept. Cheers. Jas.

  • Erlang web frameworks survey

    - by Zachary K
    (Inspired by similar question on Haskel) There are several web frameworks for Erlang like Nitrogen, Chicago Boss, and Zotonic, and a few more. In what aspects do they differ from each other? For example: features (e.g. server only, or also client scripting, easy support for different kinds of database) maturity (e.g. stability, documentation quality) scalability (e.g. performance, handy abstraction) main targets Also, what are examples of real-world sites / web apps using these frameworks? EDIT: Starting a bounty in hopes that it will get some conversation going

    I am working on a project in which i have to distribute different ad's per day, the ad's in form of array are: $ad = array( 'attribute1_value' => "12", 'attribute2_value' => "xyz", 'attribute3_value' => 'http://example.com', 'attribute4_value' => 'data'); The logic i am using with switch case : $day = date('w',time()); switch ($day) { case '0': if($day == '0') { $count = 0; echo $ad; $count++; } else { $count = 7; echo $ad; } break; case '1': if($day == '1') { $count = 1; echo $ad; $count++; } else { $count = 8; echo $ad; } break; Problem is if i have ~15 ad's then i want to distribute ad/day, date('w') output's the present day but after day 7 i.e saturday, on sunday ad number 8 initiate. I have to implement this scenario using date function. Also i have to send ad's to those user who are not experience this ad before. I am not expert in php, as a beginner working in php/mysql.

I now need to have a MS Word Macro that I can search for a character and then extend the search to another character and extract the details into a vb variable from the first to the last character. Thereafter I need to search for the next occurrence of the first character and repeat the exercise. When all have been processed the last search must inform me that there are no more. During the searches I need to identify the section numbers where I find the searches and be able to get them in VB variable. Any assistance will be greatly appreciated. Regards Mac

  • Solutions for software using many calls to a server

    - by Val
    I am developing software that uses many calls to a server. On a client side it's a Silverlight application. Almost every time a user clicks on a button in it, it sends 1-5 WCF calls to a server. There can be up to dozen or so users at a time. The server is a database server that serves data to a client. I am an intermediate level developer and am thinking about caching some data and syncing my changes from time to time. Are there any official solutions or technologies for it, like, patterns and such?

  • Using automated bdd-gui-tests to keep user-documentation-screenshots up do date?

    - by k3b
    Are there developpers out there, who (ab)use the CaptureScreenshot() function of their automated gui-tests to also create uptodate-screenshots for the userdocumentation? Background: Whithin the lifetime of an application, its gui-elements are constantly changing. It makes a lot of work to keep the userdocumentation uptodate, especially if the example data in the pictures should match the textual description. If you already have automated bdd-gui-tests why not let them take screenshots at certain points? I am currently playing with webapps in dotnet+specflow+selenium, but this topic also applies to other bdd-engines (JRuby-Cucumber, mspec, rspec, ...) and gui-test-Frameworks (WaitN, WaitR, MsWhite, ....) Any experience, thoughts or url-links to this topic would be helpfull. How is the cost/benefit relation? Is it worth the efford? What are the Drawbacks? See also: Is it practical to retroactively write specifications documenting a system via automated acceptance tests?

  • using a wiki for requirements

    - by apollodude217
    Hi, I'm looking into ways of improving requirements management. Currently, we have a Word document published on a Web site. Unfortunately, we cannot (to my knowledge) look at changes from one revision to the next. I would greatly prefer to be able to do so, much like with a wiki or VCS (or both, like the wiki's on bitbucket!). Also, each document describes changes devs are expected to meet by a given deadline. There is no collection of accumulated app features documented anywhere, so it's sometimes hard to distinguish between a bug and a (poorly-designed) feature when trying to make quick fixes to legacy apps. So I had an idea I wanted to get feedback on. What about: Using a wiki so that we can track who changed what when (mostly to even see if any edits were made since the last time one looked). Having one, say, wiki page per product rather than one per deadline, keeping up with all features of the product rather than the changes that should be implemented. This way, I can look at a particular revision of the page to see what the app should do at a given point in time, and I can look at changes to the page since the last release for the requirements to be implemented by the next deadline.

To put some context, we are developing two different products (one is an enterprise search engine based on Apache Solr) and several enterprise search projects. We are facing a lot of versioning issues and i think Hudson will solve this problems. They argued about its productivity and learning curve What Hudson's benefits would you spotlight?

  • I'm porting my app from iOS to Android: what do I need to know?

    - by kubi
    What pitfalls should I avoid? What Java language paradigms do Objective-C developers consistently misunderstand? I learned to program in Java, but I have worked in nothing but Objective-C for years now. How are the design patterns different between Android and iOS? If you've made the transition yourself, what parts of Android confused you or took you longer to learn than it should have? Is Eclipse the best OS X IDE for Android? For the record, my app is very strongly tied to UIKit and Foundation, so the word "porting" may be a misnomer; I'll actually be completely rewriting it for Android. No code reuse. Also, I'm doing this to learn Android, so I'd rather fail at the port and learn Android than take a shortcut.

  • Internal and external API architecture

    - by Tacomanator
    The company I work for maintains a successful SaaS product that grew "organically" over the years. We are planning to expand the line with a suite of new products that will share data with the existing product. To support this, we are looking to consolidate business logic into a single place: a web service layer. The WS layer will be used by: The web applications A tool to import data A tool to integrate with other client software (not an API per se) We also want to create an API that can be used by our customers that are capable of using it to create their own integrations. We are struggling with the following question: Should the internal API (aka the WS layer) and the external API be one in the same, with security and permission settings to control what can be done by who, or should they be two separate applications where the external API just calls the internal API like any other application? So far in our debate it seems that separating them may be more secure, but will add overhead. What have others done in a similar situation?

  • Is Windows 7 written in Xaml? [closed]

    - by Jordan
    Is Windows 7 written using Xaml? Edit Wow, so much hate for such a little question. I'm not an idiot. I know what XAML is. I use it every day. I was just curious whether some of the visual features were laid out with XAML, or if XAML was incorporated in some way to the product. I'm sorry if it is a programming sin not to know what Windows 7 was written in. I mean, I know Windows XP et al used C++/C, I've used Win32 quite a lot (and MFC and .NET).
