• PostgreSQL, Ubuntu, NetBeans IDE (Part 2)

  - by Geertjan

  Now let's create the start of a CRUD application on the NetBeans Platform, using Hibernate and PostgreSQL to do so. Here's what I see in NetBeans IDE after setting things up as outlined yesterday: The NetBeans Platform CRUD Tutorial should get you up and started creating the NetBeans Platform application. Open the generated "persistence.xml" in Design mode and then switch the persistence library to Hibernate. The Here's the application structure: The Hibernate module that you see above has this content: Here's the result: And here's the source code: http://java.net/projects/nb-api-samples/sources/api-samples/show/versions/7.3/misc/NBPostgreSQL

• Implementing Ads on any page in your Windows 8 XAML app–part 1

  - by nmarun

  Let’s look at how you can implements ads on any page in your win 8 app. Before you get to your application, you need to create Ad Units in the MS Pubcenter site. Once you have set up your account with payout and tax details, go to the Setup tab and you’ll see something like below. There are a few options for the sizes of the ad units as shown on the Pubcenter site. Remember that these screenshots are just to give you some reference. The actual positioning of the ads in your apps is decided by you...(read more)

• Is it reasonable for REST resources to be singular and plural?

  - by Evan

  I have been wondering if, rather than a more traditional layout like this: api/Products GET // gets product(s) by id PUT // updates product(s) by id DELETE // deletes (product(s) by id POST // creates product(s) Would it be more useful to have a singular and a plural, for example: api/Product GET // gets a product by id PUT // updates a product by id DELETE // deletes a product by id POST // creates a product api/Products GET // gets a collection of products by id PUT // updates a collection of products by id DELETE // deletes a collection of products (not the products themselves) POST // creates a collection of products based on filter parameters passed So, to create a collection of products you might do: POST api/Products {data: filters} // returns api/Products/<id> And then, to reference it, you might do: GET api/Products/<id> // returns array of products In my opinion, the main advantage of doing things this way is that it allows for easy caching of collections of products. One might, for example, put a lifetime of an hour on collections of products, thus drastically reducing the calls on a server. Of course, I currently only see the good side of doing things this way, what's the downside?

• How do you find partners for open source projects?

  - by static_rtti

  I've created a few open-source projects in the past, and had some success. The process was generally the following: I'd start alone, create something that works, promote it, and finally (maybe) get some contributions. I have less that to contribute to open-source now, but I still have ideas and can still code :) So I wonder if there is a place or a way to meet people (online), discuss ideas and design, and then start working together on the project? The reason I'm thinking about an online way to do this, with strangers, is that while I do have programmer friends, we only very rarely have the same needs and interests at the same time. It seems to me that it would be easier to find such in match in the online global community. Any insight?

• OO Software Architecture - base class that everything inherits from. Bad/good idea?

  - by ale

  I am reviewing a proposed OO software architecture that looks like this: Base Foo Something Bar SomethingElse Where Base is a static class. My immediate thought was that every object in any class will inherit all the methods in Base which would create a large object. Could this cause problems for a large system? The whole architecture is hierarchical.. the 'tree' is much bigger than this really. Does this sort of architecture have a name (hierarchical?!). What are the known pros and cons?

• Java Phones: How to set up JTAPI?

  - by Adam Tannon

  I want to use JTAPI (1.4 - latest) to create an app that will call my phone whenever I need it to. I downloaded JSR043 (JTAPI specification) and have been reading the API docs and it seems pretty straight forward with respect to how to code JTAPI. However I seriously doubt that getting a Java app on my laptop to call my cell phone doesn't require some 3rd party or middle man service provider and possibly other entities/configurations as well. So I ask: besides using the JTAPI in my Java code, what do I need to install or set up to have a Java app that calls my phone? Thanks in advance!

• Do search engines rank internal redirects negatively?

  - by siverd

  A client is in the late stages (code complete) of a website redesign and unfortunately hasn't implemented 301 redirects to point high traffic pages to the new URL's. As I understand it our only option at this point is to create redirects within the CMS. Our CMS allows us to do this: www.mysite.com/category/current-page.html will redirect to www.mysite.com/new-category-name/new-page.html The site now uses custom logic on our 404 page to check this list of redirects and if one exists forwards the user to the new-page.html I understand that using 301 redirects would be the correct way to maintain our page rank but I think that would require a code change which isn't possible. Question How will search engines respond to this? Will they wait until the redirect happens and allow us to keep our page rank (authority, trust, etc) or will they see the 404 page and down-rank us? Worst case...will they make our new-page.html start from a rank of "0"? Thanks for your help.

• What method do I use to manage an app-specific background process?

  - by Simon Dubois

  I am developing an application with different behavior depending on the arguments : "-config" starts a Gtk window to change options, start and close the daemon. "-daemon" starts a background process that does something every X minutes. I already know how to use fork/system/exec etc... But I would like to know the main logic of such application to : restart or refresh the daemon when configuration change. keep only one instance of the daemon. I have read that killing the daemon to restart it is not a clean way to do. How other applications do ? (ubuntuone, weather forecast, rss feed working with notification area) Thanks for your help. PS : I don't want to create a system-wide daemon, just a user application with a background process.

• Is it OK to push my code to GitHub while it is still in early development?

  - by marco-fiset

  I have some projects that are in a very early development state. They are nowhere nearing completion but I do host them (as public repos) on GitHub because: I have multiple computers and I want access to my code everywhere I want a backup for my code I want it to be easy if someone wants to collaborate in some way I use GitHub Issues as a poor man's project management software Is it OK to publish a project on GitHub even when it is very early in the development? I am a bit concerned about someone to come by and say OMG this is total BS, this code is so bad! while looking at unpolished/still in development/not tested code. What are your practices when you start new public projects? Do you wait until you have something substantial to show or you create a bare repo directly on GitHub and start from there? I used GitHub throughout this post but this applies to every code hosting service out there.

• New Job Over Budget

  - by moneylotion

  I recently started a new job as a contract developer, and my non-developer boss of about two weeks ago gave me the task to re-create an app from another language and developer that he will reuse with multiple clients (replacing the front-end), that I estimated would take longer than his estimate of 12 hours. Two weeks later, I'm 230% over-budget. I admit this was my 2nd web app, I had been a wordpress developer in the past, so I am somewhat new to code igniter, but not shabby php by any means. My boss hired me knowing this and I was clear that it would take longer than his 12 hours. He's seen me in the office on task for 2 weeks, he should be somewhat prepared for this bill. Do I expect the full amount of hours, or do I filter against how much of learned? Can I bill for research as a developer?

• How do you handle domain logic that spans multiple model objects in an ORM?

  - by duality_

  So I know that business logic should be placed in the model. But using an ORM it is not as clear where I should place code that handles multiple objects. E.g. let's say we have a Customer model which has a type of either sporty or posh and we wanted to customer.add_bonus() to every posh customer. Where would we do this? Do we create a new class to handle all this? If yes, where do we put it (alongside all the other model classes, but not subclass it from the ORM?)? I'm currently using django framework in python, so specific suggestions are even more wanted.

• Apple Developer Program ( Company or single )?

  - by fragant1996

  Me and my brother are both undergraduates in CS. Each one of us has a iPhone and a Macbook. So we decided to develop for the iOS devices. Now we want to create a Apple Developer account, but we just want to have 1 account. Should we share one "single developer account" OR one company account? The price is the same. Since we are both "just" students, we don't have a registered company. 1. Which one should we take ? 2. What are the differences ?

• How should my local git workflow work?

  - by Anonymous -

  At home, I have a server that is running some software (on a LAMP stack, but only accessible internally). I have another machine and a laptop that I both use for developing said software. What is the best workflow for me? Should I have a repository on my local server, create a live branch, staging branch and development branch, then checkout the development branch from my laptop/development PC to work on, commit that back when I'm done, then merge the development branch with the staging branch for testing, before further merging to the live branch? Would I simply checkout the production branch to my /www/var/ on my server? Or am I thinking/going about this all wrong? Thanks.

• What are some ways to texture map a terrain?

  - by ApocKalipsS

  I'm working with XNA on a 3D Game, and I'm trying to have a proper and nice environnement. I actually followed a tutorial to create a terrain from a heightmap. To texture it, I just apply a grass texture on it and tile it a number of times. But what I want to do is to have a really realistic texturing, but also generate it automatically (for example if I want to use Perlin noise to generate a terrain and then texture it). I already learned about multi-texturing, loading a map file with different colors for different textures, but I don't think this is really efficient, for instance for cliffs or very steep areas it will tile a texture badly as it's a view from the top. (Also, I don't know how I'll draw roads or dirt paths with that.) I'm looking for an efficient solution to realistically texture mapping procedurally-generated terrain.

• InputLayout handling

  - by Kikaimaru

  Where are you supposed to store InputLayout? Suppose i have some basic structure like. class Mesh { List<MeshPart> MeshParts } class MeshPart { Effect Effect; VertexBufferBinding VertexBuffer; ... } Where should I store input layout? It's a connection between vertex buffer and specific pass, i can live with just 1 pass but I still have diffferent techniques so i need at least an array with some connection to effecttechniques, but I would appriciate something not crazy like dictionary. I could also create wrapper for Effect and EffectTechnique, but there must be some normal solution.

• How to cross-compile programs for the Raspberry Pi with gcc?

  - by InkBlend

  I am fond of using gcc to compile small little C and C++ programs on my main computer. However, I also have a Raspberry Pi, and, being a 700-MHz single-core computer, I would prefer to not have to do my development work on it every time I want to create a binary for it. How (for I know that there's a way) do I cross-compile my program for the Raspberry Pi using my x86 laptop? And is there a way that I may compile C(++) programs on the Pi but produce an x86 binary? If it's any help, "The SoC is a Broadcom BCM2835. This contains an ARM1176JZFS, with floating point..." (according to the official Raspberry Pi FAQ).

  SharePoint 2010 Training: more information This is one of those rare occasions when I get to write about what I’m working on in my consulting life. I’m a very lucky guy, I get to work on some very tough and challenging solutions for clients around the world. In working on such problems, I face the best challenges which help me be a better consultant. A better consultant is a better trainer. There is no substitute for real world experience. As an example, Winsmarts started working on a product with Din ERP that would bring ERP functionality into SharePoint. Not influenced by marketecture, and the only driver being success at customer, as an architect for this endeavor, I experimented with and decided against technologies such as Silverlight. We subsequently invested heavily in JavaScript when the prevalent browser was still IE6. It wasn’t easy to create an amazing amount of functionality in JavaScript, but over time we enriched the product and today we have a very compelling Read full article ....

• how to give meaningful id to the things in database

  - by gcc

  There are a lot of manuals. I am trying to create an database to hold information of these documents. But, there is a small problem. How can I give meaningful id to the manuals? Are there any standard or logic behind the giving meaningful id to the documents? If there is no standard, can you tell me how I should do that? example: table : manual id | manual name EDIT: Not Meaningful ID 1 or M1 or foo 2 C2 bar 3 P123 name ... ... ... (i) (ii) (iii) (i) Not meaningful for me because if some item deleted, there can be gap. ex 1 33 100. (ii) random character can be confusing when one try to give a name to new manual (iii) Why giving name is not preferred is because finding a name to the manual as ID is hard after 500 manuals. Meaningful : New ID * Can be easily produced even if after 1000 manuals * Should not be so complicated

• C# Timers for game development

  - by Valentin

  Hi, all! I want to find out the best way of creating time based events in games. Lets talk for example about Texas Holdem Poker. Server can handle thousands of tables and in every table we have timers: turn timer, hold seat timer and so on. What is the best way of timers realization for this purpose? Is System.Timers.Timer class can handle this or it will be more reasonable to create a separate thread with sorted time queue (for example an ascending sorted list with int values which represent time in ms remained)? Thanks in advance, Valentin
