  • LibGDX - SpriteBatch's .draw() method requiring float[]

    - by just_a_programmer
    Please excuse my lack of knowledge with LibGDX, as I have just started learning it. I am going through some simple tutorials, and in one of them, I draw a string onto the screen like so: // the following code is in the main file in the core project folder: // this is in the create() method: private SpriteBatch batch; batch = new SpriteBatch(); // this is in the render() method: batch.draw(batch, "Hello world", 200, 200); I am getting an error saying: The method draw(texture, float[], int, int) in the type SpriteBatch is not applicable for the arguments (SpriteBatch, int, int) So, LibGDX wants a float array to draw instead of a string? Thanks in advance.

  • I am the Webmaster now. Where do I start? [closed]

    - by John C
    I just changed jobs and will soon be in charge of a custom-built ASP.NET CMS and website for a fairly large corporation with global offices. I have IT and developer FTE resources available to me but I am trying to build a list of branding, project, and functionality points to review. What guides or lists can/should I use to evaluate this website before I begin adding features, creating new projects, or even redesigning and redeveloping the site? (I have been a webmaster/designer/developer for small, WordPress/Drupal sites for 10 years. I have been an unofficial webmaster (director/content manager) for a large site for 3 years (no direct development control over Sharepoint administration, IIS, or hosting ... but everything else, I did. Analytics, email, advertising, social, SEO, etc.).) Thank you!

  • Testing Git competence

    - by David
    I hire a lot of programmers for tiny tasks. I very clearly specify that the tasks can only be completed by making a pull request on GitHub. Unfortunatelly, so many programmers do not know Git and often the programmers cannot complete the project due to not understanding/being willing to learn Git, even after they have undertaken the programming of the task. This is bad both for me and for the programmers. Sometimes I end up arguing for why it is inefficient that they just send me a zip file containing the code. Therefore, I am looking for an online service to certify that the programmers know how to make a pull request so I do not waste their nor my time. The certificate should be free for the coders, but may cost me. It is important that the course just focuses on exactly what is needed to make a clean pull request so it should not take more than 5 minutes to go through. Does such a thing exist?

  • Template standard controls for an entirely new look and feel

    - by T
    This is the  Ineta Live player without the O’Data Feed.  It is a good example of taking the plain Media Player provided with the Encoder install and re-templating it to make it your own.  It also has a custom scrub control that is added in.  I generally put my tempates in a separate resource file.  On this project, I discovered that I had to include the template at the document level because I needed the ability to attach some code behind to fire change state behaviors.  I could not use the blend xaml behaviors for change state inside the template because the template can’ determine the TargetObject. Version 1.01 – 6/10/09 (wow how did a week slip by)

  • What issues are there for doing freelance work?

    - by Telos
    I'm considering doing some contract work on the side of my normal job. I know that it will kill my free time, but I figure I can control when I'm doing projects and then get a little extra money or even eventually make it my full time job. But as I've never done this before, I'm wondering what issues people face to do this kind of work. For instance: how do you find customers? What difficulties do you normally face on a project? How do you deal with projects that are too large for one programmer to effectively complete? What about projects that need other skill sets (for instance web design for a web app?)

  • Is it better to concentrate on one or two research projects throughout undergrad?

    - by AruniRC
    Currently in the 4th semester of engineering in an Indian university. The thing is - is it better to do as many short-lived projects/research work on diverse topics of computer science or stick to one/two projects consistently throughout my undergraduate years? Case in point: currently working on an image-processing project that promises to carry on for a year or so (as per the prof). Does this seem like being over-specialized at too early a level? Although taking on too many things will spread me out thin and in all probability not end up getting any meaningful work done. Especially as I hope to apply for grad school in the US. Would really appreciate any views and suggestions on this.

  • Is there a purpose for using pull requests on my own repo if I am the only developper?

    - by marco-fiset
    So I got started with a real project of mine on GitHub and things are going pretty well and ideas are flowing a lot faster than I initially thought. In order to keep things organized, I setup some branches so I can develop different features separatly. Now when I push my branch to GitHub, I have that section where I have two buttons : Pull Request and Compare with the name of the branch I recently pushed to. I understand the purpose of the Compare button but I don't get why I would want to create a pull request on my own repo. Can someone explain me why I would do that? Is it useful to make pull request on my own repo if I am the only developper?

  • We Heart Discussion Forums (and Know You Do Too)

    - by oracletechnet
    It's not generally known, but Oracle (via Oracle Technology Network) hosts one of the largest discussion forums instances (forums.oracle.com) on the planet (founded in 2001), containing nearly 10 million messages from 1 million registered users. That's a whole lot of conversations! And we really, really value those conversations - they span almost every conceivable technical subject across hundreds of products and technologies. More often not - and this is by design - those discussions are stewarded by community volunteers, many of whom are Oracle ACEs (who in fact earned their ACE stripes that way). And so, I am very happy to tell you that we have just initiated a project with our platform partner, Jive Software, to upgrade that platform to the most current, modern version available. The end result should be a vastly improved user experience for everyone involved, in all dimensions. There are many, many details to work on in coming weeks, but we'll keep you posted - and, when needed, come back to you for advice and suggestions. For now, we just wanted to share the good news!

  • When should an API favour optimization over readability and ease-of-use?

    - by jmlane
    I am in the process of designing a small library, where one of my design goals is to use as much of the native domain language as possible in the API. While doing so, I've noticed that there are some cases in the API outline where a more intuitive, readable attribute/method call requires some functionally unnecessary encapsulation. Since the final product will not necessarily require high performance, I am unconcerned about making the decision to favour ease-of-use in my current project over the most efficient implementation of the code in question. I know not to assume readability and ease-of-use are paramount in all expected use-cases, such as when performance is required. I would like to know if there are more general reasons that argue for an API design preferring (marginally) more efficient implementations?

  • Modules already committed, client doesn't pay, what should I do?

    - by John
    So the story is simple, early stage EU portal hired me to do some extra modules. I got all the source code for local testing, did my job, committed new code. Now I am out of this project but client still haven't paid me yet and he is not even thinking about that. It has been couple of months and no contract was signed so I can't take any legal actions. What should I do with all the source code? Sell it? Run exact copy of that portal? Make all portal publicly available?

  • Have you worked with a well designed application?

    - by Vilx-
    Inspired by this question, I started wondering - is there or has there ever been such a thing as a "well designed application"? One where the architecture would be perfect and no refactoring would ever be needed; code would be easy to read and understand even for someone new to the project; changes could be done with a 100% certainty that they won't break anything; etc? I must admit that whatever codebases I've worked with, they've all been more or less a mess. Even code that I start myself only stays organized at the start, and then slowly deteriorates as the time passes. I'm even starting to accept this as part of life and can't figure out whether I should be worried about that or not. So... is there such a thing as a "well designed application"? Or is all our code so shitty that there isn't even a point in trying to make it better, because it will never be good anyway?

  • Please Help to bring back power to my machine

    - by Acess Denied
    I Have a samsung N150plus netbook That I have been using for a while now. I left it on and plugged to a wall outlet and went to bed. I dual boot ubuntu and win7. I tried to update the win7 to sp1 and I dozed off. I woke up and saw the machine has been booted to ubuntu and logged in as guest, which translate to mean one of my room mates have tried to use the machine and they all have denied using my machine. I tried to reboot to windows and then it appears to have no cpu, hard disk and cpu fan activity. only one led seems to come on when i plug it in. its only the led that indicate the machine is powered on powers steadily. I really cant afford to buy a new machine now and I need the machine to complete my last project in school for my last year. Help Please

  • How important is the unit test in the software development?

    - by Lo Wai Lun
    We are doing software testing by testing a lot if I/O cases, so developers and system analysts can open reviews and test for their committed code within a given time period (e.g. 1 week). But when it come across with extracting information from a database, how to consider the cases and the corresponding methodology to start with? Although that is more likely to be a case studies because the unit-testing depends on the project we have involved which is too specific and particular most of the time. What is the general overview of the steps and precautions for unit-testing?

  • What diagrams, other than the class diagram and the workflow diagram, are useful for explaining how an application works?

    - by Goran_Mandic
    I am working on a small Delphi project, composed of two units. One unit is for the GUI, and the other for data management, file parsing, list iterating and so on.. I've already made a class diagram, and my workflow looks like hell- it's too complex, even for anyone to read. I've considered making a dataflow diagram, but it would be even more complex. A use case diagram wouldn't be of use either. Am I missing some diagram type which could somehow represent the relationship between my two units?

  • Django - how should I implement generic apps that have dependencies on other generic apps?

    - by MikeRand
    Hi all, I'm using Marty Alchin's Django app that creates historical records (add, change, delete) based on models found in other Django apps (found in chapter 11 of Pro Django). Question: how do I implement this historical_records app into my other generic Django apps while still maintaining loose coupling? For example, I have a generic app (forecast) that manages a Forecast (of any other model). For one project, I'd like to use historical_records so that I can track changes to a Forecast instance. But I don't want to require all future projects that might want to use forecast to also use historical_records. Any guidance would be greatly appreciated. Thanks, Mike

  • Pros and Cons of Session Replication

    - by techsjs2012
    Do I really need Session Replication? I am working on a number of web projects for a firm. Most of the projects are about one or two pages of input and then doing a save to a mysql database. Very Basic projects. My SA's are pushing to try to get session replication working in JBoss but I don't really see any need for it and all of its overhead. We need load balancing and clustering so if the server does go down we can move the new requests to the backup service but I am not to big in session replication. This is very low volume projects. In my eyes what is the odds of a user being in the project as the server goes down on the one or two pages. I need to convince the SAs that session replication is an un-necessary complication in this instance. I am looking for pros and cons of session replication so that I can better structure my argument.

  • How to solve cyclic dependencies in a visitor pattern

    - by Benjamin Rogge
    When programming at work we now and then face a problem with visitors and module/project dependencies. Say you have a class A in a module X. And there are subclasses B and C in module Y. That means that module Y is dependent on module X. If we want to implement a visitor pattern to the class hierarchy, thus introducing an interface with the handle Operations and an abstract accept method in A, we get a dependency from module Y to module X, which we cannot allow for architectural reasons. What we do is, use a direct comparison of the types (i.e. instanceof, since we program in Java), which is not satisfying. My question(s) would be: Do you encounter this kind of problem in your daily work (or do we make poor architectural choices) and if so, how is your approach to solve this?

  • wkhtmltopdf displaying text as blocks

    - by making3
    We're using wkhtmltopdf in a web project (nodejs/compoundjs). We've gotten it working how we wanted on our machines (using the --use-xserver switch). However, when I try to run this on our Ubuntu server 12.04 (without the ubuntu-desktop package), the PDF cannot use the switch. When we disable the switch, the PDF displays any characters as blocks (image below). How do I resolve this without installing ubuntu-desktop and running x server? I've found liberation fonts, which installing ttf-liberation and fonts-liberation did not help. And urw-fonts, but I have yet to find an Ubuntu equivalent. EDIT: It just hit me, this doesn't matter if I'm on the server or not. On my development machine (Ubuntu 13.04 desktop), I can run the following, which produces the same blocks: wkhtmltopdf http://google.com google1.pdf While this prints out the pdf properly: wkhtmltopdf --use-xserver http://google.com google2.pdf My version of wkhtmltopdf is 0.12.0.

  • Can you change a license once you pick one?

    - by Adam
    I am working on a product that I don't feel is completely ready but I have a set of users that are very interested in using it now as "alpha" testers. I would like to give them the product now for free as "alpha" testers, but I would like to later license the software. Is this possible? Can anyone point me to any links/books/articles/etc? Thanks. EDIT: Due to the lack of my clarity and the reponses to the question I thought I should add this statement. I haven't decided if I am going to close-source or open-source this project yet. The user base that wants to get their hands on it now has kind of surprised me and I was concerned about what my options are as far as being able to give it to them now as open-source and later change to closed-source, or even vice versa. Thanks to everyone who has answered and commented. I appreciate it the insights.
