• 12.04: I need a new network card - and I think this one may work?

  - by Jason Malone

  I found this list of compatible USB wireless network adaptors: http://www.cyberciti.biz/tips/linux-usb-wireless-compatibility-adapter-list.html Listed here is the Belkin F5D8053. I'm looking for a store to buy a suitable adaptor in locally and I can't find that particular adaptor - but I can see a Belkin F7D4101az. I think this is simply a newer model - but a Google search for "ubuntu belkin f7d4101az" brings no results - not even people trying to get it to work. Nothing. So I didn't want to purchase it without being sure. There's really only one PC shop that sells this sort of stuff around here - so here's a list of all my available options: http://www.pcworld.co.uk/gbuk/wireless-cards-adapters/xx_7088_70095_xx_xx/xx-criteria.html I'd really like to get one today, because I have a lot of work to do and don't really want to have to wait a week for a new adaptor - I spent 6 or 7 hours last night trying to get my Dell 1450 to work with no luck. Any help would be much appreciated.

• How to calculate shot angle and velocity to hit a moving target?

  - by Guen

  I am developing a 2D Android game and I am making an aiming algorithm for AI projectiles to hit enemies either following a path, or free moving. At the moment it just calculates where the target will be after a distance and fires a projectile to meet it at that distance. Of course this means varying the projectile speed to meet the target. Does anyone have any tips for a simple-ish algorithm (optimal-ish) to calculate when the projectile needs to fire and where it needs to aim if it can only travel at a constant velocity? Say the projectile goes twice the speed of the target? The only way I can think of involves searching and seems quite large.

• How do you get users to rank their software enhancement needs?

  - by Lego Stormtroopr

  I've inherited a legacy software system, and have been tasked with performing usability and system upgrades. While there's nothing bad with the system, from discussions with the users, there are "small" usabilty issues that need to be addressed. At this stage I'm the lone developer on this system, and apart from testing I don't use the system at all, so its difficult for me to know what issues may exist or are percieved to exist. I'm going to have some time to speak with them all and discuss what they percieve to be good/bad or indifferent about the system. Since its essentially just me for the time being my time is limit. So I was considering asking them to imagine that I'd only be able to do one change, have them all write privately what they'd want that one change to be, and then helping them rank those, but I'm hoping for other tips as well. What techniques exist for getting users to explain their wants, needs, and requirements, while also having them rank them by importance or desirability?

• Entity System and rendering

  - by hayer

  Okey, what I know so far; The entity contains a component(data-storage) which holds information like; - Texture/sprite - Shader - etc And then I have a renderer system which draws all this. But what I don't understand is how the renderer should be designed. Should I have one component for each "visual type". One component without shader, one with shader, etc? Just need some input on whats the "correct way" to do this. Tips and pitfalls to watch out for.

• Learning MySQL Query optimization

  - by recluze

  I've been doing web/desktop/server development for a while and have worked with many databases (mysql mostly). I've come to the point in my career when I need to have someone look at my queries because they're 'kind of slow'. I believe it's now time to start learning query optimization. While I know the basics of index and joins etc., I'm not familiar with how to use, say, the EXPLAIN output to improve performance of my queries. I have not been able to find any online material that starts with the basics and takes me to application. Getting a book is not an option right now so I'm looking for tips about how to proceed with this. I hope this question is general enough not to get closed.

• Architecture driven by users, or by actions/content?

  - by hugerth

  I have a question about designing MVC app architecture. Let's say our application has three main categories of views (items of type 1, items of type 2...). And we have three (or more in future) types of users - Admins, let's say Moderators and typical Users. And in the future there might be more of them. Admins have full access to app, Moderators can visit only 2/3 type of items, and Users can visit only basic type of items. Should I divide my controllers/views/whatever like this: Items "A", Items "B", Items "C", then make them 100% finished and at the end add access privileges? Pros: DRY option Cons Conditional expressions in views Or another options: Items "A" / Admin, Items "A" / Moderator / Items "B" Admin ...? Pros: Divided parts of application for specific user (is that pros?) Cons: A lot of repeated code I don't have great experience in planning such things so it would nice if you can give me some tips or links to learn something about it.

• When going for an interview for web development at an agency, can a real example be expected?

  - by KPO

  I just started coding a year ago. By "coding" I mean HTML(5), CSS(3), and only a few times I implemented AJAX and JavaScript. I am interviewing for a position that expects me to know HTML, CSS, JS, JQuery, and AJAX. I am good with HTML5/CSS3 and somewhat ok with js. If I go for an interview, will they expect me to write code during the interview? I do have a live website as an example and snapshots of past projects that I sent to them. I am a little nervous, so any tips or something from your experience I can learn will be helpful.

• Building Website with JAX-RS (Jersey)

  - by 0xMG

  Is it discouraged/not-common to build Websites (not web-services!) using Jersey or any other JAX-RS implementation ? I didn't find any guide/tutorial/article regarding that.. At first impression , it seems to me that building website using Jersey (with JSPs as Viewables) is easier and more efficient than using Servlets & JSPs. If anyone did it before , I will be pleased to get tips, Do's & Don'ts, best practices etc... And maybe a good tutorial.

• How would I go about updating my electronic circuit simulator's 'electricity'?

  - by liqwidice

  I have made an application which allows the user to place down wires, power sources, and inverters on a virtual circuit board. All connections between tiles are automatic, as shown here: As you can see in the last image, the updating of power throughout this grid is not yet functioning. I think I understand how to do this updating conceptually, but getting it to work in my program is appearing to be much more difficult than I first imagined. My source code can be found here. If you have any tips as to how to I might approach this monstrous task, please let me know. EDIT The goal here is to simply get a working application. Getting tiles to pass on power to their neighbors is quite easy, but the tricky part is getting wires to "unpower" after the removal of a power source. The size of the grid is just 18x18, so efficiency really isn't a factor, for those wondering.

• "Unverifiable code failed policy check" for a closed source assembly

  I'm attempting to dynamically load some (purchased) assemblies from resource streams in a C# program during an MSI installation routine, but I'm getting "Unverifiable code failed policy check".

• npoi export from datatable

  - by Iulian

  I have an asp.net website that will generate some excel files with 7-8 sheets of data. The best solution so far seems to be NPOI, this can create excel files without installing excel on the server, and has a nice API simillar to the excel interop. However i can't find a way to dump an entire datatable in excel similar to CopyFromRecordset Any tips on how to do that , or a better solution than NPOI ?

• requestRouteToHost android

  - by Sam

  Greetings everyone! I'm getting rather fed up with android's ConnectivityManager class. I've been trying for 5 hours to get the requestRouteToHost to work. I'm running my code on the emulator but the requestRouteToHost always fails. I know I have connectivity because I called getActiveNetworkInfo() and it was connected. I've added the ACCESS_NETWORK_STATE and CHANGE_NETWORK_STATE permissions to no avail. Any tips would be greatly appreciated. Sam
