• When dealing with a static game board, what are some methods to make it more interesting?

  - by Ólafur Waage

  Let's say you have a game board that you look at. It does not move but there is some action going on. For example Chess, Checkers, Solitaire. The game I'm working on is not one of this but it's a good reference. What are some methods you can apply to the game or the design that increases the appeal of the user to the game. Of course you can make it prettier but what are some other methods you can use? For example: Visual cues, game design changes, user interface arrangement, etc.

• Why don't more companies hire remotely?

  - by James

  I keep hearing about the desperate recruiting efforts of companies in tech hubs such as SF and NYC. However, every time I'm contacted by a startup I'm told the position is on-site and working remotely isn't possible. Let me clarify that these are tech startups. They should be very comfortable with the idea of using technology to get things done and connect teams together. With the housing market the way it is, many of us can't relocate even if we wanted to pay the higher cost of living. Why are so many companies still stuck in the industrial mindset of butts in seats?

• Fixing IP Renewal After Laptop Suspend

  - by Cerin

  I have a laptop running Ubuntu 10.04, and I've noticed that with some wifi networks, but not all, I'm unable to reconnect after coming out of suspension. I've tried both Network Manager and Wicd management daemons, and both get through validation, but get hung up on "Acquiring IP address...". The only solution I've found is to reboot the machine, after which it acquires an IP address very quickly. What's the underlying issue here? What would be a more efficient way to resolve the problem? EDIT: I've noticed that if I open Wicd and manually press "Connect", it fails to acquire an IP. However, if I do nothing and let it automatically try and connect, it acquires an IP and connects just fine...

• Having trouble with font on this blog?

  - by TechTwaddle

  Sometimes when I open this site on other PC’s the font of the posts turns out be very small and it can be a pain to read the text. Not sure if you’ve noticed the ‘Customize’ bar on top of the page, so I thought I’ll let know. This bar helps you customize the way you want the page to look and saves the settings for you so you don’t have to change it every time. You can change the font size and the main page positioning. The white arrow marks in the image above shows the settings I find convenient.

• Viewport.Unproject - Checking if a model intersects a large sprite

  - by Fibericon

  Let's say I have a sprite, drawn like this: spriteBatch.Draw(levelCannons[i].texture, levelCannons[i].position, null, alpha, levelCannons[i].rotation, Vector2.Zero, scale, SpriteEffects.None, 0); Picture levelCannon as being a laser beam that goes across the entire screen. I need to see if my 3d model intersects with the screen space inhabited by the sprite. I managed to dig up Viewport.Unproject, but that seems to only be useful when dealing with a single point in 2d space, rather than an area. What can I do in my case?

• Any way to edit Warcraft MDX or MDL Animated models?

  - by Aralox

  I have been searching for a while for a way to get an animated mdl or mdx model into any 3D animating software (such as Blender), but so far have not had any success. I found a few methods of getting textured static mdx or mdl models into Blender/Milkshape/Hexagon, but no one seems to have written an importer that deals with the mdl/mdx model's keyframe animation. On that note, if anyone knows of a way of importing a keyframe-animated 3DS model into Blender, me and alot of people would appreciate it if you could let us know. Thanks for any help! :) PS: For anyone curious about static MDL or MDX - Blender, see here: http://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/Import-Export/WarCraft_MDL

• Inputting cheat codes - hidden keyboard input

  - by Fibericon

  Okay, here's what I want to do - when the player is at the main menu, I want them to be able to type in cheat codes. That's the only place I want it to work. I don't want to give them a text box to type into. Rather, I want them to simply type in a word (let's say "cheat", just for simplicity sake) that activates the cheat code. I only need to capture keyboard input when the window is in focus. What can I do to accomplish this?

• Should I tell a departed coworker about their "sev 1" defect?

  - by noahz

  I had a co-worker leave our company recently. Before leaving, he coded a component that had a severe memory leak that caused a production outage (OutOfMemoryError in Java). The problem was essentially a HashMap that grew and never removed entries, and the solution was to replace the HashMap with a cache implementation. From a professional standpoint, I feel that I should let him know about the defect so he can learn from the error. On the other hand, once people leave a company, they often don't want to hear about legacy projects that they have left behind for bigger and better things. What is the general protocol for this sort of situation?

  - by user70886

  Installed 12.04 from CD to clean hard drive but on first boot up says problems with compiz-core. Clicked continue with it not installed. After I sent info for help; it came back with some packages are not up to date. Said I need to update compiz-core and libylib2.0-0 Cancelled the process to send info (after second time) but it wont cancel and it wont load the desktop. What do I do now? Right click will let me create a new folder/document or organise desktop by name etc but I cannot see the usual system bar or left menu items. Is there a way to load the terminal and reload the desktop. If this was windows I'd use cntrl alt delete and run explorer to fix the desktop.

• What Design Pattern is seperating transform converters

  - by RevMoon

  For converting a Java object model into XML I am using the following design: For different types of objects (e.g. primitive types, collections, null, etc.) I define each its own converter, which acts appropriate with respect to the given type. This way it can easily extended without adding code to a huge if-else-then construct. The converters are chosen by a method which tests whether the object is convertable at all and by using a priority ordering. The priority ordering is important so let's say a List is not converted by the POJO converter, even though it is convertable as such it would be more appropriate to use the collection converter. What design pattern is that? I can only think of a similarity to the command pattern.

• Quality Assurance tools discrepancies

  - by Roudak

  It is a bit ironic, yesterday I answered a question related to this topic that was marked to be good and today I'm the one who asks. These are my thoughts and a question: Also let's agree on the terms: QA is a set of activities that defines and implements processes during SW development. The common tool is the process audit. However, my colleague at work agrees with the opinion that reviews and inspections are also quality assurance tools, although most sources classify them as quality control. I would say both sides are partially right: during inspections, we evaluate a physical product (clearly QC) but we see it as a white box so we can check its compliance with set processes (QA). Do you think it is the reason of the dichotomy among the authors? I know it is more like an academic question but it deserves the answer :)

• How to synchronise the acceleration, velocity and position of the monsters on the server with the players?

  - by Nick

  I'm building an MMO using Node.js, and there are monsters roaming around. I can make them move around on the server using vector variables acceleration, velocity and position. acceleration = steeringForce / mass; velocity += acceleration * dTime; position += velocity * dTime; Right now I just send the positions over, and tell the players these are the "target positions" of the monsters, and let the monsters move towards the target positions on the client with a speed dependant on the distance of the target position. It works but looks rather strange. How do I synchronise these properly with the players without looking funny to them, taking into account the server lag? The problem is that I don't know how to make use of the correct acceleration/velocity values here; right now they just move directly in a straight line to the target position instead of accelerating/braking there properly. How can I implement such behaviour?

• LL(8) and left-recursion

  - by Peregring-lk

  I want to understand the relation between LL/LR grammars and the left-recursion problem (for any question I know parcially the answer, but I ask them as I don't know nothing, because I am a little confused now, and prefer complete answers) I'm happy with sintetized or short and direct answers (or just links solving it unambiguously): What type of language isn't LL(8) languages? LL(K) and LL(8) have problems with left-recursion? Or only LL(k) parsers? LALR(1) parser have troubles with left or right recursion? What type of troubles? Only in terms of the LL/LALR comparision. What is better, Bison (LALR(1)) or Boost.Spirit (LL(8))? (Let's suppose other features of them are irrelevant in this question) Why GCC use a (hand-made) LL(8) parser? Only for the "handling-error" problem?

• 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

• How to route KVM virtual machine audio to Ubuntu 11.10 host using virt-manager?

  - by iGadget

  I've been using KVM in combination with Virt-Manager and Remmina at a fair success up until now. The issue I need to solve now is to get audio from a virtualized Windows XP and make it audible on the Ubuntu 11.10 host. Remmina / RDP works for 'simple' audio (system sounds and such), but when the source gets trickier (e.g. Flash audio), Remmina / RDP messes up. So I figured I'd just connect to the machine directly using Virt-Manager. Unfortunately, it seems that even though I have successfully configured the AC97 audio device on WinXP, it's unable to get it's output to the Ubuntu host. This is probably because Virt-Manager uses VNC (and AFAIK, VNC doesn't transport audio). Does anyone know if there is a solution to fix this? I've heard of Spice, but the installation required so much voodoo last time I checked, I figured I'd let that solution boil to maturity a little longer ;) But perhaps there are other options I haven't thought of yet (which don't require switching to VirtualBox / VMware)...

• What sources of sample work should be used in a job interview?

  - by Joan Venge

  One of my friends has been laid off. When I talked to him, he said they didn't let him take a copy of anything he worked on. When he asked how to show what he worked on to another employer in an interview, he was told that he will have some explaining to do. Should we, as programmers, be allowed to take samples of our previous work former employers? What sources of code should we be expected to show off in an interview? When almost every employer asks for sample work, how are we to justify what can be sent? Is it our responsibility to maintain after-work projects for our entire life so we have code we can legally show to our next employer?

• Ubuntu One not syncing and not providing feedback

  - by Joe

  Firstly, I apologize for not being more specific with my problem, but Ubuntu One is just not providing me with any information. It appears to be working, it states that "syncronization in progress..." but it never actually syncronizes (by never I mean 3 days). When I first selected a folder to sync using Ubuntu One it took on the order of hours to sync over 500MB of files - it uploaded the folder hierarchy first and populated the folders over a few hours. That is not happening at all now. Please let me know if there is a way I can get more information out of Ubuntu One that I can post and hopefully resolve this issue. Thanks, Joe

• 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.

• Are there compatibility issues opening Visual Studio Professional projects in Visual Studio Express, and vice versa? [migrated]

  - by theGreenCabbage

  Disclaimer: I have taken a look at the 50+ StackExchange forums to find the right place, and it seems /Programmers/ is the most suitable Exchange for this. If this is the wrong place to ask this, however, please let me know - I will personally delete the thread. I am in the process of downloading a single license for Visual Studio 2013 for my firm of 2-3 developers. One license is approximately $498.00 USD. As a small firm, our funds are short, but since we will be creating commercial software, we decided we will be needing the features of the Professional edition. At the same time, our decision is to use the Express edition for the rest of the two developers. My question is - will there be compatibility issues between Express projects and Professional projects for Visual Studio?

• Xfce session will not login from login prompt. Why?

  - by hydroparadise

  Well, not sure how I did it, but for some reason I am unable to get past the login screen on Xfce. What's odd is that I had set the machine up (from install) to login automatically. Then when I finish rebooting after installing sudo apt-get install openssh-server and sudo apt-get install vnc4server all the sudden I am getting prompted for my password. I proceed to type my password (successfully might I add) to login, the screen goes black for a second, then brings me right back to the same password prompt. I am able ssh in(now), but I get no love from workstation login. Maybe vnc4server is the culprit? What did I do? And can I fix it? EDIT: The guest account, however will let me login no problem. What gives? I have a sneaking feeling that this could be permission issue.

• BPM Parallel Multi Instance sub processes by Niall Commiskey

  Here is a very simple scenario: An order with lines is processed. The OrderProcess accepts in an order with its attendant lines. The Fulfillment process is called for each order line. We do not have many order lines, and the processing is simple, so we run this in parallel. Let's look at the definition of the Multi Instance sub-process - Read the full article here.

• How do I share my jQuery plugin with the world?

  - by Billy Moon

  I made a plugin for jQuery, which I think is quite useful. It combines an animated colours plugin with an easings plugin, and adds a completely new feature of being able to refer to colours numerically (more useful in hex notation, so 0xff00cc for example) and therefore manipulate them mathematically more easily. I created a repository on github, and it sits there, nobody looks at it. Mostly, I would like people to look at it, use it, and improve it, so I can use the improvements and so on. I think this idea of numerically manipulating colors could be interesting. It makes it easy to change the hue without changing the saturation for example. Combined with animated colors, I think something interesting could be done, but I don't know what exactly. How do I let people know it (or any other project) is there..? I was going to post it on http://plugins.jquery.com which is currently down. Are there any other outlets for this kind of code?

• Prevent azure subdomain indexation

  - by Leg10n

  Let me explain my situation, I have an azure website (with azurewebsites.net sub domain), and a custom domain.com, built with asp.net MVC Both are being indexed by Google, but I've noticed the custom domain is being penalized and it doesn't show up in results, it only shows when I search for "site:domain.com" I want to remove and block the azurewebsites.net subdomain from Google. I've read the "possible" solutions: Adding robots.txt: won't work, because the subdomain and the domain are the exact same content, so subdomain.azures.net/robots.txt will lead to domain.com/robots.txt, removing the domain as well. Adding the tag, is the same situation as the previous point. I'm using a CNAME register to redirect the domain to the subdomain, so I can't redirect to a sub directory. Do you have any other ideas?
