• How do I show a minimap in a 3D world?

  - by Bubblewrap

  Got a really typical use-case here. I have large map made up of hexagons and at any given time only a small section of the map is visible. To provide an overview of the complete map, I want to show a small 2D representation of the map in a corner of the screen. What is the recommended approach for this in libgdx? Keep in mind the minimap must be updated when the currently visible section changes and when the map is updated. I've found SpriteBatch(info here), but the warning label on it made me think twice: A SpriteBatch is a pretty heavy object so you should only ever have one in your program. I'm not sure I'm supposed to use the one SpriteBatch that I can have on the minimap, and I'm also not sure how to interpret "heavy" in this context. Another thing to possibly keep in mind is that the minimap will probably be part of a larger UI, is there any way to integrate these two?

• What should I do next in my life as a programmers? [closed]

  - by user1769787

  I am doing work in asp.net (mvc) in my starting days of programming 2 years ago.I have done work on some web-apps. I am not comfortable with c# but have working skill in jQuery and front-end development. from a year I do UI kind of work. Now someone can suggest me what should I do for next. Should I learn asp.net mvc or I should go for PHP then I can do some wordpress development. The problem is I never found small people use asp.net rather then PHP.( I am not currently employed). Someone can help me what should I do. I have front-end skill (not in programming) so what Is best for me to do.

• NetworkManager not populating resolv.conf

  - by Cerin

  I recently upgraded from 11.10 to 12.04, and now NetworkManager isn't populating /etc/resolv.conf when connecting to wireless networks, when it had been working perfectly in 11.10. I'm not seeing any explicit errors in either the NM UI or in syslog. How do I diagnose what's wrong? Edit: If I try to run resolvconf, I get the error "resolvconf: Error: /etc/resolv.conf isn't a symlink, not doing anything." What should it be a symlink to and/or how do I get NM to populate it? This says the symlink should point to /run/resolvconf/resolv.conf, but that file does not exist on my system.

• Learning Programming, Suggestions for a roadmap

  - by RisingSun

  Hi, Some background first- I am new to programming and have discovered it rather late in life; Like many hobbyists, my introduction to the subject has been through php/jquery (yes, i know the popular mood around here... they-are-not-real-programminng-languages ;-) ). I like to believe that I am reasonably competent at what I do in my other life and this developing addiction to coding has taken a very heavy toll on my professional prospects. This is the question: What programming languages next? (No plans to ditch php in the immediate future, that will involve rewriting much of my code) Any absolutely essential books I must read? Is it necessary to join a college/university course? Do I need to ditch my other profession to continue serious learning? My goals are: Develop a solid understanding of the science and art of programming. Continue to work on my own web application (Hands on learning suits me best) I am something of a generalist interested in everything from UI to database performance

• How to increase the bus factor and specialize at the same time?

  - by bizso09

  In agile pair programming it is recommended to switch pairs every now and then so as to increase the bus factor of the team. That means, most people in the team should work on different parts of the system at different times so that everyone has an understanding of it. Now it is impssible that everyone has an expert level of understanding of each part of the system. That's because people are urged to specialize in one area of expertise. If you are an expert database admin, what's the point of working on the user interface of the system when you switch pairs? You will not be able to do such a high quality job as someone who has extensive experience in UI design. How can you increase the bus factor and make sure that you have specialization in your team?

• How to design a separated tutorial mode?

  - by Sylpheed

  I'm working on a "social" game that's about 90% completion. One of the remaining features is the tutorial mode. Basically, the tutorial mode will restrict the user to access some parts of UI and limit the features (like store items). The tutorial will only progress if a certain event is triggered, specifically following the tutorial. The code is ready and we already have an "almost" working game. The problem is I haven't foreseen the tutorial mode while I was doing those 90%. My requirement is there shouldn't be any loading/transition from tutorial mode to normal mode. This means I have to pick up the progress from the tutorial (no re-rendering of assets and stuff). How should I design this in a way where I won't touch anything from my old code? I want it to be as easy as just plugging it in. I don't want to jam the tutorial in my old code since this will lead to many bugs.

• How are crossplatform/multiple-OS C++ projects planned in terms of code and tools?

  - by Nav

  I want to create a project in C++ that can work in Windows, Linux and Embedded Linux. How are projects created when they have to work across many OS'es? Is it first created on one OS and then the code slowly modified to be ported to another OS? Eg: to me, the Linux version of Firefox appears to be created as a Windows project and a separate Linux project with a different code base, since Firefox behaves a bit different in Windows and Linux. Although the source code download is surprisingly a single link. If QT is used for UI, Boost threads for threading, Build Bot for CI and NetBeans/Eclipse/QT Creator for an IDE, would a person be able to minimise the amount of code re-write required to get the project onto another OS? Is this the right way to do it, or are such projects meant to be created as two entirely separate projects for two separate OS'es?

• Can't edit/drag-and-drop widgets in QtCreator in Unity, Gnome3 - ok

  - by Maksim

  I have QtCreator 2.4.1 (Qt 4.7.4) installed on Ubuntu 12.04 LTS x86. When I try to change UI - drag-and-drop any widget (buttons, label, etc.) it won't let me do it, like it's read-only. The icon when I drag is a circle with a line through it. I've found that problem in Unity and it's suggested to install Gnome3 shell - Can't edit/drag-and-drop widgets in QtCreator I tried to install Gnome3 and it works fine as expected. But the question, is there any other way to work proper with QtCreator in Unity?

• How to save during real-time collaboration

  - by dev.e.loper

  I want multiple users to edit same document. Problem I'm facing is when a new user joins, he might see an outdated document. How do I make sure that new users get most recent changes? Some solutions I thought of: Save on every change. I don't like this solution because it will slow things down on UI and put load on db. When new user joins, trigger save on all other clients. After other clients saved, load document. With this there can be inconsistency still. Any other suggestions would be helpful.

• Right tool for the job(html5 vs silverlight)

  - by Jargo

  I have been tasked to develop a web based offer request application for bathrooms and I am asking opinions on which tool should I choose. I have narrowed options down to two (html5 and silverlight). Most of the application consists of basic UI elements that could be achieved with html4. However most challenging part is the design view for the bathroom. User first defines size of the bathroom by giving dimensions. When the dimensions are defined the application renders an empty bathroom floorplan and user can start dragging&dropping furniture on to it. Some furniture have rules where they can be dragged. For example sinks can only be dragged next to a wall. I know that this functionality can be achieved with silverlight but what about html5 ? I know that Canvas element can be used to draw graphics, but can it render the bathroom smoothly as user drags a piece furniture on it?

• What is it going here in my solution?

  - by bbb

  I am a asp.net mvc programmer and if I want to start a project I do this: I make a class library named Model for my models. I make a class library named Infrastructure.Repository for database processes I make a class library named Application for business logic layer And finally I make a MVC project for the UI. But now some things are confusing me. Am I using 3-tier programming? If yes so what is n-tier programming and which one is better? If no so what is 3-tier programming? Some where I see that the tiers namings are DAL and BIZ. Which one is correct according to the naming convention?

• Pros and cons of developing modern services in Java

  - by r3mus

  I'm interested in the philosophical and architectural justification (or lack thereof) in using Java to develop in today's modern world (exclude mobile/embedded platforms of course). Why would one choose to develop (or not develop) a back-end in Java? Why would one choose to develop (or not develop) a front-end UI in Java? Why do large enterprises lean towards developing in Java rather than adopt more modern (and standardized) technologies? *disclaimer: I'm not a fan of Java in the enterprise, I'm simply curious what drives enterprises to continue the trend.

• Graphic demonstrating emphasis of front end in web apps

  - by sohail

  I remember stumbling across an amusing graphic a year or so ago which demonstrated the tiers of web development. The back-end was shown as a tiny box, but the front end was shown as a huge box crammed with lots of front-end technologies like AJAX, DHTML. This is all a vague recollection. Does anyone know where on the Intraweb this graphic might be? It was probably on a programming cartoon site, but I only view XKCD on a regular basis, and I couldn't find it on there. Although tagged as fun, my request does have a productive edge to it - it would be quite useful in driving home to my colleagues how UI top-heavy web application development has become.

• Hello NHibernate! Quickstart with NHibernate (Part 1)

  - by BobPalmer

  When I first learned NHibernate, I could best describe the experience as less of a learning curve and more like a learning cliff.  A large part of that was the availability of tutorials.  In this first of a series of articles, I will be taking a crack at providing people new to NHibernate the information they need to quickly ramp up with NHibernate. For the first article, I've decided to address the gap of just giving folks enough code to get started.  No UI, no fluff - just enough to connect to a database and do some basic CRUD operations.  In future articles, I will discuss a repository pattern for NHibernate, parent-child relationships, and other more advanced topics. You can find the entire article via this Google Docs link: http://docs.google.com/Doc?docid=0AUP-rKyyUMKhZGczejdxeHZfOGMydHNqdGc0&hl=en Enjoy! -Bob

• Kicked out when logged in?

  - by acidzombie24

  When i log into ubuntu the screen goes black as it were logging in but then i am back in the login screen. I can login as guest (i should disable that). I can login via ssh. The last time i had no issues was when i used it this morning and the only unusual thing i did was shutdown via ssh (i think i wrote shutdown now) which had ubuntu hang after showing the shuting down screen for many seconds (i kind of assumed it shut down properly since the UI froze as well and it usually takes less time). Whats the easiest way to fix this w/o reinstalling? Its a brand new install and so it probably takes me 10mins to recopy/setup everything so i may just do that -edit- using 12.04

• how to learn Java

  - by Sarang

  This question I am asking because I couldn't find any source which gives complete overview of java development. I just want to know where java technology currently in market & what is preferable for development ! Java always remain top programming language for development point of view. However, java is combo of, j2ee, j2me, jsp, jsf, spring, other frameworks, ui components, jndi, networking tools and various other "J" are there ! However, learning java is definitely dependent on the development requirement, but still, to be a well-experienced java developer, what is the organised way of learning java? What is preferable in current technology ? and what is deprecated, currently ?

• Distance Education in Computer Science - HCI

  - by Rionmonster

  I have been a software engineer / graphic designer for a few years and have recently been considering furthering my education in the field. (It was actually a very generous Christmas present) I would primarily be interested in something like Human Computer Interaction or a similar "creative technology" that involves heavy UI/UX Design, prototyping or Information Architecture. Anyways - I still plan on working full-time and was looking into part-time distance programs and was wondering if anyone had some experience with pursuing a similar degree (either from a distance or in-person) and could share their experiences. Thanks!

• Windows Phone 7 Design Template

  Windows Phone 7 Design Template Expression Blend is a wonderful design environment for WP7 (Windows Phone 7) but for quickly visualizing a concept nothing beats Illustrator! I am excited about WP7 and decided that having a solid .ai template would prove invaluable. Some of the details of the WP7 UI Design and Interaction Guide are a bit fuzzy (literally) but I was able to generate some useful layout guides, character styles, and symbols. While the template does not cover every aspect of the guide I think it is a good launching point; if you find it useful and extend it please share your updates (I created the template in CS4, if you have problems in earlier versions let me know).Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• How many developers do I need to build a website like Freelancer.com in about 3-5 months? [closed]

  - by Sam

  I have been asked to make a list of people that I need to build something similar to freelancer.com. Not exactly same, has a few more features to it too but I can't really get my head around the whole freelancer.com site. I have built a social networking site from scratch which is 70% of Facebook and 20% Google+ in about 5 months with raw PHP, JS, CSS and Ajax. I dont think it will take me more than a month or something to build the whole freelancer.com from scratch. Please suggest anything that should I pay attention to. I am thinking about: 2 php developers 1 mysql engineer 1 network/server engineer 1 graphics artist 1 UI developer Time frame: 20 days Is this a good estimation?

• Gnome3 pointer barrier not working with dual monitors

  - by Nathan

  I have a dual monitor setup using Gnome3. Misc Info : In the past I used Fedora, there was a pointer barrier between my two monitors in the upper left corner so that I can hit the hot corner when moving from the right monitor to the left monitor. Problem : However, with my new Ubuntu installation, the barrier no longer exists and my mouse pointer glides straight to the next screen. This makes that hot corner nearly useless. I've looked around, messed with the values in /usr/share/gnome-shell/js/ui/layout.js, but I can't figure out how to make the pointer barrier work. may someone suggest hot to get the full utilization of hot cornet.

• migrating from struts2, looking for a new framework

  - by adhg

  We are supposed to start a relatively big project that will require lots of computation and analysis. Presentation (UI) for the end user is very crucial (graphs, tabels...) So far we've been using struts2. It's ok+. It has some drawbacks (specially if you work with tiles and all that XML) but if you get the lingo - you're ok. One option on the table is to continue using struts2 with jquery and all the other stuff that we've been doing for so long. Alternatively, I think we have an opportunity to learn something new and maybe a bit better then struts2. My question is this: Anyone has migrated from struts2 to something new and can share the experience. Or had some great experience witha particular java framework. Many thanks for any pointers.

• What is the situation about OpenGL under Ubuntu Unity and Gnome3?

  - by user827992

  In a GNU/linux distribution is usually installed Xorg as main graphical server, it operates with a client-server logic, a special windows is designate as desktop environment and this special windows can handle all the eyecandy stuff like decorations, icons and effects. The problem is that the latest UI heavily relies on hardware acceleration, Unity is an overlay on Compiz and the Gnome-shell also require an active driver for the GPU to work well: the problem is: on the same OS I can find multiple implementations of OpenGL who is handling my OpenGL buffer? how the OpenGL buffer is managed compared to the other windows? how can I be sure that my OpenGL implementation is glued to the hardware and is not related to the client-server logic of Xorg? For example I have tried the clutter library and I have only experienced problems under both Unity and GTK/Gnome, no problem under other OS.
