• Banshee keeps copying the same music files to my portable player over and over

  - by Dave M G

  I have Banshee 2.6.0, and I connect my Android phone by USB to sync my music collection of about 1500 songs. For the most part, it works reliably. However, on every sync, it deletes, and then recopies the same 62 songs each time. After that, everything works, and the sync completes successfully. As far as I can tell, these 62 songs are mostly recent additions to my collection, but not all of them, and I can't see any other commonality of significance. This is only a problem because the transfer speed when working within Banshee is quite slow, so this is eating up time. Sometimes I need to make a transfer and go, but I can't, because I'll have to wait for progress bars take their sweet time. I have tried to completely clear out the music files on the phone and resync. I have tried rescanning the music collection. What do I do to fix this irritation?

• Speed up content loading

  - by user1806687

  I am using WinForms Sample downloaded from microsoft website. The problem is, that the model loading time is quite long, using: contentBuilder.Add(ModelPath, ModelName, null, "ModelProcessor"); contentManager.Load<Model>(ModelName); even a simple model, such as a cube with no textures, takes 4+ seconds to load. Now, I am no expert on this, but is there anyway to decrease loading time? EDIT: I've gone thru the code and found out that calling contentBuilder.Build(); ,which comes right after contentBuilder.Add() method takes up most of the time.

• 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

• Best language or tool for automating tedious manual tasks [closed]

  - by Jon Hopkins

  We all have tasks that come up from time to time that we think we'd be better off scripting or automating than doing manually. Obviously some tools or languages are better for this than others - no-one (in their right mind) is doing a one off job of cross referencing a bunch of text lists their PM has just given them in assembler for instance. What one tool or language would you recommend for the sort of general quick and dirty jobs you get asked to do where time (rather than elegance) is of the essence? Background: I'm a former programmer, now development manager PM, looking to learn a new language for fun. If I'm going to learn something for fun I'd like it to be useful and this sort of use case is the most likely to come up.

• Can manager classes be a sign of bad architecture?

  - by Paul

  Lately I've begun to think that having lots of manager classes in your design is a bad thing. The idea hasn't matured enough for me to make a compelling argument, but here's a few general points: I found it's a lot harder for me to understand systems that rely heavily on "managers". This is because, in addition to the actual program components, you also have to understand how and why the manager is used. Managers, a lot of the time, seem to be used to alleviate a problem with the design, like when the programmer couldn't find a way to make the program Just WorkTM and had to rely on manager classes to make everything operate correctly. Of course, mangers can be good. An obvious example is an EventManager, one of my all time favorite constructs. :P My point is that managers seem to be overused a lot of the time, and for no good reason other than mask a problem with the program architecture. Are manager classes really a sign of bad architecture?

• Updating "Inactive" Chunks

  - by Conner Bryan

  In my game, the only chunks (4x4 areas of tiles) in memory are the ones that the player is in. However, chunks need to have updates applied to them over time. A (likely) well-known example would be MineCraft: even if the player isn't in a chunk, the wheat still needs to grow over time. My current solution is to call a method and pass in the time since the chunk was active.. but what if the chunk depends on nearby chunks for information, i.e. vines spreading or similar? Is there any reasonable solutions to this problem, or should I simply not depend on nearby chunks?

• How do I allow full brightness control on Unity?

  - by ChrisL

  When I use the brightness changing buttons Unity changes the brightness by two levels each time to create a nice effect. However, I only have about 10 different brightness settings and so this effect has caused a reduction in brightness settings to 5. I change my brightness regularly to suit the lighting in the room I'm in, but am unable to do this so effectively now that the number of levels has been reduced. Is there any way of turning off this brightness effect and controlling my brightness setting more sensitively? Thank you for your time. EDIT: It may not be 2 levels it changes at a time but 3, I've worked this out as the brightness control panel allows you to set the brightness accurately and there seem to be a couple of settings that the button misses completely when I change the brightness with the buttons.

• Android Application for Final Year Project [closed]

  - by user1070241

  I hope this is the right place to post this question. Basically, I'm about to choose a Final Year Project for my third and final year in BSc Computer Science. I have worked with different apps and therefore I do have some experience with the Android SDK Platform in general. However, my question is this, how do you think an Android based project would go down with potential employers? I personally don't think the complexity of this project is lower than other projects proposed by my university. Please let me know what you think, and do share any experiences that you have had with this, if any. Thank you very much.

• 13.04 - Extenal monitor plugged on laptop HDMI shows image but lags a lot

  - by Thiago Fassina

  It uses an Nvidia GeForce GTS 250M. When I plug in the monitor, it shows some images but with bad FPS and lagging a lot. For example, when I move the mouse pointer, it leaves a trail that vanishes from time to time. I didn't install Nvidia drivers because every time I did this on past versions I ended up with an unbootable system. On past versions I just gave up trying to use the monitor cause it never showed anything regardless of what driver I installed. But since 13.04 ALMOST made it, I'll make another tries. ps.: Works perfectlty on Windows 7/8

• Preparing yourself for Code challenges

  - by Daniel Fath

  Just a few days ago I discovered Codility, and I tried their challenges. And I must say. I got my behind handed to me on a platter. I'm not sure what the problem was, but I'll lick my wounds and wait for the solution to come out and compare it with my own. In the meantime, I want to get ready for the next challenge so I'm reading their previous blog posts and seeing how to solve their previous problems. There are a lot of new things I haven't heard about like (Cartesian trees, various sort algorithms, etc.) So, how does one prepare for such challenges (especially the O(x) time and space complexity). What should I read to prepare for such a task?

• Is it wrong to use a boolean parameter to determine behavior?

  - by Ray

  I have seen a practice from time to time that "feels" wrong, but I can't quite articulate what is wrong about it. Or maybe it's just my prejudice. Here goes: A developer defines a method with a boolean as one of its parameters, and that method calls another, and so on, and eventually that boolean is used, solely to determine whether or not to take a certain action. This might be used, for example, to allow the action only if the user has certain rights, or perhaps if we are (or aren't) in test mode or batch mode or live mode, or perhaps only when the system is in a certain state. Well there is always another way to do it, whether by querying when it is time to take the action (rather than passing the parameter), or by having multiple versions of the method, or multiple implementations of the class, etc. My question isn't so much how to improve this, but rather whether or not it really is wrong (as I suspect), and if it is, what is wrong about it.

• Why use C++ when C works for large projects equally well?

  - by Karl

  Before I start, please DO NOT make this into a C vs C++ flamewar. This question has nothing to do with which language is better or not. Period. I have read that C++ is said to be fit for large projects. After all, it makes managing code easier. OO and other features, for example the STL. But then why use C++ when C works equally well for large projects? Take the example of the Linux kernel. Or GNOME. Or even Windows I guess, it is written in C right? So why bother at all with the complexity of C++ (templates and all that), when C works well and this is not just a statement, but proper examples have been quoted. If it works for projects of magnitude of the kernel, why is C++ preferred or why is C not used for almost all projects?

• What Are Some Tips For Writing A Large Number of Unit Tests?

  - by joshin4colours

  I've recently been tasked with testing some COM objects of the desktop app I work on. What this means in practice is writing a large number (100) unit tests to test different but related methods and objects. While the unit tests themselves are fairly straight forward (usually one or two Assert()-type checks per test), I'm struggling to figure out the best way to write these tests in a coherent, organized manner. What I have found is that copy and Paste coding should be avoided. It creates more problems than it's worth, and it's even worse than copy-and-paste code in production code because test code has to be more frequently updated and modified. I'm leaning toward trying an OO-approach using but again, the sheer number makes even this approach daunting from an organizational standpoint due to concern with maintenance. It also doesn't help that the tests are currently written in C++, which adds some complexity with memory management issues. Any thoughts or suggestions?

• How to determine the right amount of up front design?

  - by Gian

  Software developers occasionally are called upon to write fairly complex bits of software under tight deadlines. Often, it seems like the quickest thing to do is to simply start coding, and solve the problems as they arise. However, this approach can come back to bite you—often costing time or money in the long run! How do we determine the right amount of up front design work? If your work environment actively discourages you from thinking about things up front, how do you handle that? How can we manage risk if we eschew up-front thinking (by choice or under duress) and figure out the problems as they arise? Does the amount of up front design depend entirely on the size or complexity of the task, or is it based on something else?

• C# on ubuntu 12.04

  - by Deus Deceit

  Is C# a good choice for ubuntu programming? E.g unity, or applications that will run on ubuntu? Am I doing good wanting to learn C# when I'm determined to stick with ubuntu and develop on it or for it? If not, can you give me reasons why? And which languages would be better than c# for ubuntu development? I already know c, c++, java(basics), php, mysql, python(basics). I like to learn new stuff, but stuff that worth my time. Does C# worth my time? If c# worth my time, here's what I have done and what I need: I installed all mono packages I could find on the ubuntu standard repositories. Now I want a good tutorial to get me started. I'm a complete noob with c# so a basic tutorial and how to compile run under ubuntu 12.04 would be great.

• What you do to restrict yourself from browsing internet unnecessarily?

  - by cod3-monk-3y

  I find myself browsing internet all the time and most of the time unnecessarily. I do find some interesting stuffs, learn something new daily. But I think most of the time I browse internet without any purpose. When I finish my basic tasks such as checking email, reading couple of news and browsing stackoverflow, I either go to Digg or Stumble through different sites and I find myself lost. I want to ask those who have gone through the similar situations. How do you restrict yourself from browsing internet unnecessarily?

• What are the pros/cons of using a 3d engine for 2d games?

  - by mrohlf

  What pros or cons should a beginner be aware of when deciding between a 2d game engine (like Slick2D/Flixel/FlashPunk) and a 3d engine (like Unity) for 2d game development? I am just getting started in indie game development, though I have dabbled a bit with Game Maker, Flash, and XNA in the past. I've heard a lot of positive things about Unity, and its cross-platform nature makes it appealing, but as I understand, it's a 3d engine at its core. For a strictly 2d game, are there any compelling reasons to work with a 3d engine like Unity? Or would it just add unneeded complexity to my initial learning experience?

• Data architecture for event log metrics?

  - by elliot42

  My service has a large ongoing number of user events, and we would like to do things like "count occurrence of event type T since date D." We are trying to make two basic decisions: What to store? Storing every event vs. only storing aggregates (Event log style) log every event and count them later, vs. (Time-series style) store a single aggregated "count of event E for date D" for every day Where to store the data In a relational database (particularly MySQL) In a non-relational (NoSQL) database In flat log files (collected centrally over the network via syslog-ng) What is standard practice / where can I read more about comparing the different types of systems? Additional details: The total event stream is large, potentially hundreds of thousands of entries per day But our current need is only to count certain types of events within it We don't necessarily need real-time access to the raw data or aggregation results IMHO, "log all events to files, crawl them at a later time to filter and aggregate the stream" is a pretty standard UNIX Way, but my Rails-y compatriots seem to think that nothing is real unless it's in MySQL.

• To canvas, or not to canvas, when building browser-based games?

  - by Letharion

  Background: I have extensive development background, but the last time I coded a game was many years ago. My Javascript skills are quite limited, and I intend to improve them by building a simple game — Tetris, Pac-man, or something of that complexity level. Question: It seems to me that a fundamental choice I need to make is whether I should render on a <canvas> element or not. With a canvas, I have basic tools for rendering points, lines, and more complex things on top of that. Presumably there are, or will be, also various frameworks to help with this. Without a canvas, I could keep my objects in the DOM-tree, like a regular webpage, only quite complex, with many overlapping elements. Is one approach better than the other? Are they mutually exclusive? How do I know which to pick?

• Where to contribute a Mozilla Persona example?

  - by Serg

  I found out about Mozilla Persona today and fell in love with it completely. It really does feel like the future of account management. For the first time ever, I actually want to contribute to open source because I believe in this tech. I wrote a simple ASP.Net MVC3 demo web application showing how to login and logout users using Persona. I want devs in my language ecosystem to have a simple time learning about this by reading example code. Here is the repository: https://github.com/sergiotapia/ASP.Net-MVC3-Persona-Demo Where do I contribute this link to my repository so it's easily found? Any suggestions? It's my first time releasing code for a "big project" so to speak.
