• What naming anti-patterns exist?

  - by Billy ONeal

  There are some names, where if you find yourself reaching for those names, you know you've already messed something up. For example: XxxManager This is bad because a class should describe what the class does. If the most specific word you can come up with for what the class does is "manage," then the class is too big. What other naming anti-patterns exist? EDIT: To clarify, I'm not asking "what names are bad" -- that question is entirely subjective and there's no way to answer it. I'm asking, "what names indicate overall design problems with the system." That is, if you find yourself wanting to call a component Xyz, that probably indicates the component is ill concieved. Also note here that there are exceptions to every rule -- I'm just looking for warning flags for when I really need to stop and rethink a design.

• What liability concerns do advertising vendors raise, and how can I address them?

  - by Beofett

  One of the websites I administer wants to provide free advertising in the form of direct links to vendors at an event they are running. Up until now, there has been no advertising whatsoever on the site (or any of our other sites). The site is for a for-profit business. The idea of implicit endorsement of any vendors we advertise has been raised, which brought up the question of what we need to do, if anything, to protect ourselves from any potential problems such endorsement might create. I know that many sites have clauses in their Terms of Service that state that (in a nutshell) they are not responsible for any problems or grievances between the visitors to the site and any vendor advertised or linked. Are there other steps that a website typically takes when considering advertising, such as getting the advertiser to provide some sort of certification that their ad will not violate any trademarks or copyrighted material?

• Anisotropic and trilinear filtering?

  - by fedab

  I'm confused about the usage of trilinear filtering and anisotropic filtering in SharpDX. As far as i understood, trilinear filtering does linear filtering to the textures and in a case of LOD-change it also interpolates between the too LODs to smooth the transition. Anisotropic filtering make the texture bigger. Now it is possible to use trilinear filtering to do the same thing, due to anisotropic filtering with bigger textures. This causes a lesser blurred image, when you use anisotropy, because the interpolation is better. Now, it should be possible to use trilinear filtering and anisotropic filtering at the same time. But in the SamplerState i can only choose Filter.Anisotropy or Filter.MinMagMipLinear (should be trilinear, right?). You can see all possible filters here: D3D11 Filter Enumeration. So my question: Can you use both techniques together, if yes, how can i archieve that in SharpDX with SamplerState?

• Help making TP-Link Wireless USB Adapter TL-WN723N work consistently

  - by Savvas Katseas

  I've only recently made the jump to Ubuntu, using 11.10/64 as my only desktop OS. Everything seems to be working fine, except my USB Wireless adapter, TP-Link's TL-WN723N which is randomly connecting and disconnecting. The connection time appears to be random, too: I've experienced hours of connectivity and lots of connections/disconnections. I've tried searching for a solution, but what I find doesn't concern this specific USB adapter. I'd like some help identifying the problem... I've also recently switched to using a D-Link router as a wireless hub, which creates its own wireless/n network. Unfortunately this didn't solve my problems, as the new n network can be joined, but there's no connectivity to the internet. I know that's not much info to help others solve my problem, so please let me know of what else I can provide to make this a better question -- and possibly help others facing similar trouble. lsusb reports that I'm using Realtek Semiconductor Corp. RTL8188SU 802.11n WLAN Adapter

• Am I copy/paste programmer ?

  - by Searock

  When ever I am stuck with a particular problem, I search for a solution in Google. And then I try to understand the code and tweak it according to my requirement. For example recently I had asked a question Reading xml document in firefox in stack overflow. Soufiane Hassou gave me a link to w3schools, where I found a example on parsing xml document, I understood how the example works, but I copied the code and tweaked it according to my requirement, since I don't like typing much. So does this make me a copy/paste programmer? How do you say if a person is a copy/paste programmer ? Thanks.

• What are the most common AI systems implemented in Tower Defense Games

  - by the_Dan

  I'm currently in the middle of researching on the various types of AI techniques used in tower defense type games. If someone could be help me in understanding the different types of techniques and their associated advantages. Using Google I already found several techniques. Random Map traversal Path finding e.g. Cost based Traversing Algorithms i.e. A* I have already found a great answer to this type of question with the below link, but I feel that this answer is tailored to FPS. If anyone could add to this and make it specific to tower defense games then I would be truly great-full. How is AI most commonly implemented in popular games? Example of such games would be: Radiant Defense Plant Vs Zombies - Not truly Intelligent, but there must be an AI system used right? Field Runners Edit: After further research I found an interesting book that may be useful: http://www.amazon.com/dp/0123747317/?tag=stackoverfl08-20

• How to design software when using BDD?

  - by Léster

  I'm working on a project right now and it's my first project using BDD. Up till now, the user stories have proven themselves a very valuable weapon to understand requirements and to specify the solution in a comprehensive, easy to understand language. My question is this: now that my user stories are complete, how do I design my solution? I understand that I derive behavior tests from my user stories, and I have to do UI design, but am I supposed to use good ol' UML? I'm under the impression that when using user stories, UML is left out; is this correct? Léster

• No SQLCompact Edition Support IN VS 2013

  - by James Izzard

  Firstly apologies if this is a poor question - I am an engineer not a programmer. I have spent time moving from Visual Basic to C#. I have started C#/SQL tutorials. I have noticed VS 2013 has stopped supporting the compact edition database normally used for standalone desktop apps. Somebody has kindly written a plugin to re-implement support. I have also noticed a belief circulating that SQLite is to replace the compact edition. Would anybody be able to advise if this was accurate - I am slightly confused as to which database is best suited for desktop app development inside VS 2013. Any comment greatly appreciated. Cheers James

• adverising servers / advert delivery solutions for C#/Asp.Net

  - by Karl Cassar

  We have a website which we want to show adverts in - However, these are custom adverts uploaded by the webmaster, not the Google adverts, or any adverts the network chooses. Ideally, there would be both options. We were considering developing our own advert-management system, but looking at the big picture, it might be better to consider other alternatives. Website is currently developed in C# / ASP.Net (Web Forms) Are there any recommendations to some open-source delivery networks and/or external hosted advert delivery networks? Personally I've used Google's DFP, however sometimes it is not so easy to get a Google AdSense account approved, especially while developing a new website and it not yet being launched. Not sure if this is the best place to ask this kind of question!

• Changing email application in Preferred Applications to GMail?

  - by grm

  I'm trying to change the Preferred Application for email. I have installed the package desktop-webmail, but there is no new option under System - Preferences - Preferred Application as you would expect, infact, there is only one option there, only Evolution. According to this post it should be possible to set a custom application, but no option is available. Is it possible to setup GMail as Preferred email app so that File - Send by email works in gnome apps? This seems to be a dup of another post here, Thing is that this works fine in 10.10, but in 11.04 this method no longer work. My post above is meant for 11.04 and the question is still valid.

• Is there a variable width font that does not change width when adding effects like bold, italic?

  - by George Bailey

  NetBeans has a word wrap feature now - but if the font changes width when bold then it gets all jumpy and sometimes hard to work with. Edit: It turns out that even with Courier New that NetBeans word wrap still jumps up and down lines at a time at random. I guess that this question no longer cares for an answer. However,, it seems that there is no answer. (at least nobody has brought one up yet) I am currently using Comic Sans MS which gets wider when bold.

• cannot rename files when saving

  - by Botond Vajna

  I am using xubuntu 13.10. Since the last update, when I am saving files I cannot rename other files, there are missing buttons in context menu like rename, cut, copy, etc... let`s say I edited the file named style.css in firefox, and I want to save it, but i do not want to overwrite the original, I want to rename the original for ex: style_orig.css and save the edited file with the name style.css. for doing that I must open thunar, navigate to that file, and rename it, after that, I can save the file from firefox. let`s reformulate this question: if I want to overwrite a file, but preserve the original, then I must make a copy of the original. Well, I can not do this when saving the file from the application, I must open thunar and navigate to that file which is an additional task I have to do. It`s a waste of time.

• Remapping Shift Selection in Gnome Terminal

  - by Gowie47

  Hey so I was hoping somebody could help me out in finding a way to get shift-selection working in gnome-terminal on Ubuntu 11.10. I found the question/bug report below but neither seem to have a solution. I use Emacs for development and being able to select my current line with shift-ctrl-a/e is something I find myself trying to do every couple of minutes. I use 10.04 at work and this is possible so I am not sure what has changed. If it matters I am using Gnome 3 Shell and I use bashish to style my terminal. Thanks in advance! https://bugs.launchpad.net/ubuntu/+source/vte/+bug/546021 http://askubuntu.com/questions/31991/using-the-shift-key-in-terminal

• How to make the transition to functional programming?

  - by tahatmat

  Lately, I have been very intrigued with F# which I have been working a bit with. Coming mostly from Java and C#, I like how concise and easily understandable it is. However, I believe that my background with these imperative languages disturb my way of thinking when programming in F#. I found a comparison of the imperative and functional approach, and I surely do recognize the "imperative way" of programming, but I also find it difficult to define problems to fit well with the functional approach. So my question is: How do I best make the transition from object-oriented programming to functional programming? Can you provide some tips or perhaps provide some literature that can help one to think "in functions" in general?

• Is it possible to create a single tokenizer to parse this?

  - by Adrian

  This extends off this other Q&A thread, but is going into details that are out of scope from the original question. I am generating a parser that is to parse a context-sensitive grammar which can take in the following subset of symbols: ,, [, ], {, }, m/[a-zA-Z_][a-zA-Z_0-9]*/, m/[0-9]+/ The grammar can take in the following string { abc[1] }, } and parse it as ({, abc[1], }, }). Another example would be to take: { abc[1] [, } and parse it as ({, abc[1], [,, }). This is similar to the grammar used in Perl for the qw() syntax. The braces indicate that the contents are to be whitespace tokenized. A closing brace must be on its own to indicate the end of the whitespace tokenized group. Can this be done using a single lexer/tokenizer, or would it be necessary to have a separate tokenizer when parsing this group?

• Has anyone got Ubuntu Touch working on Nexus 5?

  - by user1628

  I have been debating whether to get a nexus 5 phone since it came out. My only fear is that I won't like android. I love ubuntu, I know that I'd love ubuntu. So I have a few question related to Ubuntu Touch: Is it easy or possible to switch between Ubuntu Touch and Android? Would I have to keep hacking the phone? Can I dual boot them? Would I lose my data every time I switch? The nexus 5 isn't mentioned here: https://wiki.ubuntu.com/Touch/Devices Does that mean it simply won't work if I follow the porting instructions? Would I have to do a bit of hacking? Has anyone got it working? Will it eventually be supported?

• 2D Pixel/sprite game in unity? [on hold]

  - by acidzombie24

  Hi I'm an absolute newbie in unity. In the past I was told unity is terrible for 2d games so I look away after looking at it for a few days. I don't remember if this was right before unity4 came out or after. I hear unity is fairly good at 2d now. I tried googling for tutorials but I'm doing it wrong. I could not find a good tetris or tic tac toe tutorial. What assets/tutorials do I want for a 2D game? Side question is what tutorials are good if I want to make a fire emblem/advance wars type game (HUD heavy grid base game)

• Carpool logical architecture

  - by enrmarc

  I'm designing a carpool system (drivers can publish their routes and passengers can subscribe to them) with WebServices(axis2) and Android clients (ksoap2). I have been having problems with the logical architecture of the system and I wondered if this architecture is fine. And another question: for that architecture (if it is ok), how would be the packages structure? I suppose something like that: (In android) package org.carpool.presentation *All the activities here (and maybe mvc pattern) (In the server) package org.carpool.services *Public interfaces (for example: register(User user), publishRoute(Route route) ) package org.carpool.domain *Pojos (for example: User.java, Route.java, etc) package org.carpool.persistence *Dao Interface and implementation (jdbc or hibernate)
