• Where To Begin To Make A Website

  - by lolyoshi

  I'm a newbie in web programming. I haven't done anything that relates to website before. Now, my new task is creating a website using Java, Jsp, HTML, CSS, mySQL, Apache and Spring Framework (MVC model). I want to know what I should research if I want my website has the function as post entries, comment entries, delete entries, edit entries, etc as a forum? Which I need to know beside above things? I don't know how to update my website automatically when there're changes in website as the top view products, the best products. I don't think I'll input or change them manually. So, which tools or language can support that? Thank for advance

• Permanent redirect domain to www subdomain without web.config

  - by Lord Simpson

  I've just set up a site via 1and1 and have run into an issue, I want to accomplish the simple task of redirecting the root domain to the www sub domain however due to complications I cant seam to find a way to get it to work. I'm on a Microsoft (asp.net) package so can't use .htaccess, also the IIS server they have doesn't have the URL redirect module installed (so can't use <rewrite> in web.config). They have built in HTTP forwarding options however if I set the root domain to redirect to the www sub domain it just infinitely redirects. Hopefully there is some obvious option/method I've missed during the past two days of searching!

• Is there an 'off the shelf' platform for making a new website similar to Elance?

  - by user17747

  I am interested in developing a website that is similar to 'elance' but for a particular vertical. Is there an 'off the shelf' platform you can recommend for getting started with this, or would I need to develop this web service from scratch? When I write 'platform' I am referring to things such as 'shopify' for e-commerce sites, or 'ning' for social websites. I want to create a multi-merchant professional services site. The site would need to support functionality such as: allowing merchants to open and manage their own profile. merchants would accept payments from customers through the site. file transfers between merchants and customers. merchant ratings by customers.

• Is Java's ElementCollection Considered a Bad Practice?

  - by SoulBeaver

  From my understanding, an ElementCollection has no primary key, is embedded with the class, and cannot be queried. This sounds pretty hefty, but it allows me the comfort of writing an enum class which also helps with internationalization (using the enum key for lookup in my ResourceBundle). Example: We have a user on a media site and he can choose in which format he downloads the files @Entity @Table(name = "user") public class User { /* snip other fields */ @Enumerated @ElementCollection( targetClass = DownloadFilePreference.class, fetch = FetchType.EAGER ) @CollectionTable(name = "download_file_preference", joinColumns = @JoinColumn(name = "user_id") ) @Column(name = "name") private Set<DownloadFilePreference> downloadFilePreferences = new HashSet<>(); } public enum DownloadFilePreference { MP3, WAV, AIF, OGG; } This seems pretty great to me, and I suppose it comes down to "it depends on your use case", but I also know that I'm quite frankly only an initiate when it comes to Database design. Some best practices suggest to never have a class without a primary key- even in this case? It also doesn't seem very extensible- should I use this and gamble on the chance I will never need to query on the FilePreferences?

• Where to advertise small open-source projects

  - by Saif Bechan

  I am searching for a good recourse where I can advertise my open source project. I have made a web-development framework which I want to make available to download, and I want to target a large audience. It is an open source project so I make no money off of it, so I do not really want to pay for advertisement. I already pay for the server where the website runs, and I have spent a lot of time developing it. I opened account on various search engines webmaster tools, so people can find it on there. I have also made a video-sharing account where I uploaded a few tutorials. This can accumulate some traffic also. Can someone recommend any more places to get your work spread.

• Licensing approach for .NET library that might be used desktop / web-service / cloud environment

  - by Bobrovsky

  I am looking for advice how to architect licensing for a .NET library. I am not asking for tool/service recommendations or something like that. My library can be used in a regular desktop application, in an ASP.NET solution. And now Azure services come into play. Currently, for desktop applications the library checks if the application and company names from the version history are the same as the names the key was generated for. In other cases the library compares hardware IDs. Now there are problems: an Azure-enabled web-application can be run on different hardware each time (AFAIK) sometimes the hardware ID for the same hardware changes unexpectedly checking the hardware ID or version info might not be allowed in some circumstances (shared hosting for example) So, I am thinking about what approach I can take to architect a licensing scheme that: is friendly to customers (I do not try to fight piracy, but I do want to warn the customer if he uses the library on more servers than he paid for) can be used when there is no internet connection can be used on shared hosting What would you recommend?

• Jr developer report bug to potential future boss [on hold]

  - by Cryptoforce

  I applied for a Web developer job in Quebec City, and they called me back for a phone interview. Everything went well, it last for over a hours, and at the end they ask me to send code simple and a portfolio, but in my research about the company and their products I found a PHP error(bug) in their app. Should I tell them or I would that make me look like a total jerk and blow my chance for a interview? I know it might sound stupid. As a junior developer I did 2 interviews they didn't go so well. I am very interested in this position part of my question is like a big lack of confidence so to make it short should I tell them about where is the error and how to fix it? Thanks

• Best/Easiest Technology for a RESTful webservice [closed]

  - by user1751547

  So I'm going to be creating a phone app + website that will need to utilize a web service. Webservices are completely outside my domain so I'm not entirely sure where to start. Does anybody have any suggestions on the technology stack I should use? (mainly in terms of ease of use and reliability) So far what I've looked at are: RoR Python + Django + TastyPie Python + Flask Microsoft WCF 3.5 PHP + some framework I would rather not do anything with Java I'm leaning towards the Python + Django + TastyPie route as it seems like it would be easy to get up and going and learn in general. My only concern with it is the reliability of the libraries (feature breaking updates, abandonment, etc). Also I would prefer to create the website with the same framework so I wouldn't have to deal with learning and using two different ones. Any advice would be helpful, thanks.

• Was it necessary to build this site in ASP.NET ?

  - by Andrew M

  From what I'm told, the whole StackOverflow/StackExchange 'stack' is based on Microsoft's ASP.NET. SO and the SE sites are probably the most complex that I visit on a regular basis. There's a lot going on in every page - lots of different boxes, pulling data from different places and changing dynamically and responding to user interaction. And the sites work very smoothly, despite the high traffic. My question is, could this have been achieved using a different platform/framework? Does ASP.NET lend itself to more complex projects where other web frameworks would strain and falter? Or is the choice pretty incidental?

• Is there really Object-relational impedance mismatch?

  - by user52763

  It is always stated that it is hard to store applications objects in relational databases - the object-relational impedance mismatch - and that is why Document databases are better. However, is there really an impedance mismatch? And object has a key (albeit it may be hidden away by the runtime as a pointer to memory), a set of values, and foreign keys to other objects. Objects are as much made up of tables as it is a document. Neither really fit. I can see a use for databases to model the data into specific shapes for scenarios in the application - e.g. to speed up database lookup and avoid joins, etc., but won't it be better to keep the data as normalized as possible at the core, and transform as required?

• Microsoft launches two new Data Centres for Azure in US to meet growing demand

  - by Gopinath

  In order to meet the growing demand for Windows Azure in US, Microsoft has launched two new data centres in US – East US and West US. With the addition of these two data centres the number of Azure data centres across the globe has grown to 8 and 4 among them are located in US. The two new data centres are providing Computer and Storage resources and few enthusiastic customers already deployed their applications. The other services like SQL Azure and AppFabric will be offered by these data centres in the coming months. The addition of new data centres is a good sign to Microsoft as the customer demand for their Cloud offering is growing. Amazon Web Services is the pioneer in Cloud Computing and they offer wider range of Cloud Services compared to Microsoft. Source: Windows Azure Blog

• Beginning HTML and CSS [closed]

  - by romani

  My goal of learning HTML and CSS is to be able to modify popular scripts such as Wordpress, vBulletin, Drupal, etc. I haven't started yet learning CSS and HTML or XHTML. I see many, many books and tutorials out there so it is difficult to make a choice. I think most of web designers were like me in the past and have read many books. So, could you tell me about 1 good book for HTML and 1 good book for CSS? and if I should read the book from cover to cover or only learning the basics is enough for modifying Wordpress, for example!

• Conditions for a traditional friends system vs. open following system

  - by Dan

  I'm just curious for everyone who is developing social sites out there. When you build a method for connecting users, do you prefer to use a following-style system (follow me, you can see all of my information and I can just choose to follow you back), or instead do you choose to have a friends-style system (I have to allow you see all of my information on your homepage, even if it is open to the public, vise versa). Why and under what circumstances do you use each? How do you manage privacy between your users? Have you use another way to connect your users? Examples of what methods you've choose and how you manage the user's privacy (private by default vs open to the web) are awesome; it could show correlation and provides an actual look.

• Multi-platform Map Application

  - by Mahdi

  I'm working on a web project (PHP, jQuery) which currently using Google Maps powering up the map functionality of the application, however we need to make it multi-platform like you can go to the dashboard and choose one from 5-10 map providers (which Goolge Maps is just one of them) to underlying your map functionality. So, as the application is supposed to show the data on map, almost in every single place we have to deal with the API provided by that specific map provider. Currently we are thinking about revising our modular structure and/or making something like an adapter for each provider to deal with their native syntax but via our standard methods. I wish to have your ideas and your experiences, specially if you ever made an interface for dealing via 2-3 different map providers. That would helps much and I really appreciate that. If you need any further information, just ask me to update the question. Update: As Vicky Chijwani suggested Mapstraction, now I'm also wondering which one is more better (pros & cons), having an adapter implemented on Javascript or PHP?

• When should I use AtomPub?

  - by Gary Rowe

  I have been conducting some research into RESTful web service design and I've reached what I think is a key decision point so I thought I'd offer it up to the community to get some advice. In keeping with the principles of a RESTful architecture I want to present a discoverable API, so I will be supporting the various HTTP verbs as fully as possible. My difficulty comes with the choice of representation of those resources. You see, it would be easy for me to come up with my own API that covers how search results are to be presented and how links to other resources are provided, but this would be unique to my application. I've read about the Atom Publishing Protocol (RFC 5023), and how OData promotes its use, but it seems to add an extra level of abstraction over what is (currently) a rather simple API. So my question is, when should a developer select AtomPub as their choice of representation - if at all? And if not, what is the current recommended approach?

• How to deal with social login

  - by Matteo Pagliazzi

  In my new web app I'm going to allow social login through Twitter (maybe), Facebook and Google and I'm in search of the best way to do it. Actually I'm using Rails with Devise + Omniauth and this is the problem: Should I ask the user to choose a password so that he can login without a social network? Or maybe the user should be able to set a password if he want (for example when editing his account?) The second way seems the best one but since Twitter doesn't provide user email and google doesn't provide an username I'll probably have to ask the user for username/email when he log in so in that case I may also ask for the password... waht do you think?

• Paying a developer in stock/fixed rate? [closed]

  - by user51648

  I have an idea for a cross platform application. It will require knowledge of several different languages, web development, and system administration/IT. I don't personally code, but I want to pay professionals to do it. I'm wondering how I should go about paying them. Yes, this will be a large project, but I want it done ASAP. Is it ok if I don't pay them by the hour? I really want it to be a set price. Also, is it reasonable to pay them in stock of the company? Like, 20%? P.S. How do I know how big a project will be in order to give the devs themselves an idea?

• Is there an open source sports manager project?

  - by massive

  For a long time I've tried to search for an open source manager game, but without any luck. I'm looking for a suitable project for a reference to my own pet project. Features like well designed data model, tournament and fixture generation and understandable match simulation algorithm would be a great bonuses. I'm especially interested in game projects like Hattrick and SI Games' Football Manager, although it is irrelevant what the particular sport is. The project should be preferably web-based as Hattrick is. I've crawled through GitHub and SourceForge, but I found only a few sports simulation projects. Projects, which I have found, were either dead or not fulfilling my wishes. Do you know any open source manager game / fantasy sports game project, which would be available as open source, OR at least any material, which would be useful when building a such project?

• Creating symlink for Postgres

  - by Edwin

  As a developer, I often ssh right into my local database, just to test my application before pushing my code. However, I find that every time I want to access Postgres, I have to type in postgres@ubuntu:~$ /usr/local/pgsql/bin/psql test whereas on my work machine, all I have to do is type postgres@ubuntu:~$ psql --dbname=test --username=user I tried creating a symlink, which was successful, but whenever I try connecting to it through this shortcut, I get the following error message: psql: could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"? How do I get this to work? In case it makes any difference, I'm using a self-compiled version of the 9.1.x series.

• Understanding the Java Ecosystem

  - by syrion

  I have traditionally had the "luxury" of being a one-man development team. I've used Python extensively, have a reasonable command of Perl, PHP, and JavaScript. My problem is Java. I can write Java code. I'm not great at it--unlike Python, I rarely make use of anything unique to Java when I'm writing it. Furthermore, my experience is mostly in simple GUI/console programming. Unfortunately, I'm currently pursuing an IT degree where Java is the lingua franca. My database class is requiring that our projects be written in Java using servlets, and I just can't wrap my head around the ecosystem. Is there a good online overview of or tutorial on how the Java web ecosystem works? I have Thinking in Java, but it's mostly just the language itself (which I understand well enough to get by). I have looked at the Sun servlet tutorial, but it seems outdated.

• Should I be paid for time spent learning a framework?

  - by nate-bit

  To give light to the situation: I am currently one of two programmers working in a small startup software company. Part of my job requires me to learn a Web development framework that I am not currently familiar with. I get paid by the hour. So the question is: Is it wholly ethical to spend multiple hours of the day reading through documentation and tutorials and be paid for this time where I am not actively developing for our product? Or should the bulk of this learning be done at home, or otherwise off hours, to allow for more full-on development of our application during the work day?

• How can I get pictures from Shotwell on the notebook to the desktop?

  - by Meng Tian

  My father has a desktop and a notebook. The desktop is way more powerful and has RAID set up, so he uses it for editing and storing his pictures. But he spends several months a year away from home. So he has a notebook for this. He imports the pictures into shotwell on his computer. He likes to organise his pictures on the notebook already, by creating and naming the right events, deleting pictures and sometimes editing a bit. When he is back home, he wants to get his pictures on the desktop, without losing the names of the events in shotwell. Sadly, one cannot merge two shotwell databases, nor is it possible to import another database. Do you know any way, I can manage this? Or did I just miss something?
