• What makes puzzle games addictive?

  - by Bryan Denny

  I'm currently developing a puzzle game for Android that is sort of along the lines of Alchemy. I was wondering what makes games like Alchemy or Bejeweled so addicting? How do I keep players interested in the game to want to play it over and over? Is it the scores? Level advancement? The challenges? What should I be doing to try and keep a player engaged with a puzzle game since they are often quite repetitive?

• Job Search Engine Url Structure Issue [closed]

  - by Justin

  Possible Duplicate: What is the best stucture of SEO friendly URL? I am working on a job board, and i'm trying to figure out a good design for URL structure. Some things that I have found through research: 100 - 150 Chars long is ideal 3-5 words in your url, according to Matt Cutts Use .htaccess to force clean urls Do not duplicate data (important) Clean and precise, describing the content Use hyphens On the homepage, I try to detect the users location based on IP, but this isn't always accurate, and not always reliable. So until they put in their city/location, I can't always use this structure but this is potentially work-able. For Searching, a form post to a results page: domain.com/jobs/[city]/[search] ie: domain.com/jobs/toronto/sales manager/ OR domain.com/search/jobs/toronto/sales manager/ or do I remove the word JOBS and just use Search. I trying to keep good search terms in the URL, but also keep it clean and concise. Can someone give me some feedback and thoughts to 'why'...

• Design pattern to handle queries using multiple models

  - by coderkane

  I am presented with a dilemma while trying to re-designing the class structure for my PHP/MySQL application to make it more elegant and conform it to the SOLID principle. The problem goes like this: Let as assume, there is an abstract class called person which has certain properties to define a generic person, such as name, age, date of birth etc. There are two classes, student, and teacher, that implements this abstract class. They add their own unique properties to it. I have designed all the three classes to include all the operational logic (details of which are not relevant in context of the question). Now, I need to create views/reports/data grids which contain details from multiple classes, for example, say, a list of all students doing projects in Chemistry mentored by a teacher whose name is the parameter to the query. This is just one example of a view, there are many different views in the application, which uses data from 3-4 tables, and each of them have multiple input parameters to generate them. Considering this particular example, I have written the relevant query using JOIN and the results are as expected and proper, now here is the dilemma: Keeping in mind the single responsibility principle, where should I keep this query? It does not belong to either Student class, or Teacher class or any other classes currently present. a) Should I create a new class, say dataView class, and design it as a MVC pattern and keep the query there? What about the other views? how do they fit in this architecture? b) Should I not keep the query in code at all, and make it DB View ? c) Am I completely wrong in the approach? If so what is the right approach? My considerations are as follows: a) should be easy to add new views later on if requirement comes, without having to copy-paste-modify code b) would like to make it as loosely coupled as possible so that if minor db structure changes happen, it does not break I did google searches on report design and OOP report generators, but all the result seem to focus on the visual design of the report rather than fetching the data. I have already taken care of the visual aspect of the report using MVC with html templates. I am sure this is a very fundamental problem with known solution, but I am somehow not able to find it (maybe searching with wrong keyword). Edit1: Modified the title to make it more relevant Edit2: The accepted answer got me thinking in the right direction and identify my design flaws, which eventually led me to find this question and the solution in Stack Overflow which gave me the detailed answer to clear the confusion.

• How do I show a minimap in a 3D world?

  - by Bubblewrap

  Got a really typical use-case here. I have large map made up of hexagons and at any given time only a small section of the map is visible. To provide an overview of the complete map, I want to show a small 2D representation of the map in a corner of the screen. What is the recommended approach for this in libgdx? Keep in mind the minimap must be updated when the currently visible section changes and when the map is updated. I've found SpriteBatch(info here), but the warning label on it made me think twice: A SpriteBatch is a pretty heavy object so you should only ever have one in your program. I'm not sure I'm supposed to use the one SpriteBatch that I can have on the minimap, and I'm also not sure how to interpret "heavy" in this context. Another thing to possibly keep in mind is that the minimap will probably be part of a larger UI, is there any way to integrate these two?

• Is SVN out of style?

  - by jitbit

  It's been only several years since I migrated from Visual Source Safe to SVN. And SVN for me is still kinda "WOW! I can do so many things! SVN is so cool!" But many people around me keep saying "SVN? Really? Meh..." And there's so many of them that I'm worried. Should I move my team to Git / Mercurial or some other fancy thing? I know I sound ridiculous and the obvious answer would be "stay with what works for YOU". SVN does work for me... But every time I create a new project in my repository I keep asking myself - may be this was the time to move? So... Is SVN really that bad? Do I miss a huge opportunity by sticking with it?

• What are the correct settings for a subdomain in ZoneEdit?

  - by user99572_is_fine

  I want to create a subdomain for a site hosted by Jimdo (a DIY website builder). Jimdo does not allow subdomains however. I am trying to find a workaround where a subdomain is hosted elsewhere but everything else remains as it is. E.g. I use their email service and I want to keep it. The domain is not hosted by Jimdo, but by a host that allows me to edit my zones. It points to the Jimdo NS. I have independent hosting where I have NS information. This is where I want to host my subdomain. My thinking was that I could use ZoneEdit as a "fork" that allows me to keep using my Jimdo page like before and, at the same time, directs a subdomain to another host. Provided this is possible: Question: How do I configure ZoneEdit CNAME or NS records to forward visitors to my website and my email to my Jimdo mail account while pointing a subdomain to another host?

During installation of Ubuntu I found option replace windows 7 by Ubuntu and I did it. now I found that windows XP has also gone and Ubuntu is occupying the area of whole hard disk. Now I want to uninstall or format the hard disk because Ubuntu is new to me and I am not comfortable with Ubuntu only right now. I want to keep both windows XP and Ubuntu. so how can I uninstall Ubuntu or format hard disk?? please help....Is the formatting is possible by inserting windows XP CD?? Or is there any other way so that without uninstalling Ubuntu I can also install windows XP?

• Downgrading from ubuntu 11.10 to 10.10, keeping installed programs

  - by Peter

  I recently upgraded from 10.10 to 11.04 then 11.10, and I'd like to revert back to 10.10. I understand that you cannot downgrade a version as easily as you can upgrade, and that I'll probably have to get the boot CD again and reinstall the whole thing. I know that I can keep most of my files by saving the /home directory, so 2 questions: Once I've gone back to 10.10, can I juts copy my old version of home over the freshly installed one? Is there a way to keep all of my installed programs, or some sort of way of getting the new install to automatically install them? Will I have to go through the tricky setups of things like TeX all over again? Thanks

• Programmer logbook application?

  - by jsoldi

  I've just released my application to the public, and I'm working on an updated version, but I really think I should keep track of ALL the code changes. In case some functionality suddenly starts failing, with a history of all the changes I made it would be a lot easier to figure out where I messed it up, in case the problem wasn't already there. The ideal would be to have a super fast computer with a huge hard drive and an application that automatically saves a backup of the whole project every time I change a line in the code, with some file comparison tool that would show me every difference between any two backed up projects, but that's not really possible for now. So, do you know any application that makes it easy for a programmer to keep track of the changes made to the source code?

• .NET Reflector Open Source Alternative

  - by bconlon

  When I found out yesterday that one of my top 5 development tools .NET Reflector will no longer be free at the end of February, I thought I'd see if work had started on a good open source alternative...and guess what...work on ILSpy is already well underway!! There seems to be a difference of opinion on what Red Gate said when they purchased .NET Reflector from Lutz Roeder in 2008. They say that they would try to keep it free, where as others think they promised to keep it free. Either way at the time I thought it was a smart purchase by Red Gate as it would raise their profile overnight within the .Net community. But not only are they going to charge $35 for v7 (which is up to them), they have also time-bombed v6 to force users to pay. This I think will lower their profile overnight within the .Net community!! Maybe they are been slightly naive in thinking the community wouldn't just write an alternative?  #

• Which programming language to get into?

  - by user602479

  I'm ending my third term in a few weeks so I have some spare time coming up. I'd like to spend it seriously digging into programming. My problem: I'm not sure which language to begin with. Just to be clear, I don't want to start a language-y-compared-to-language-z discussion. There are a some other issues that play a major role. In my 5th term I'm going to be participating in a major practical course which will include either Java or C programming. It will take a lot of time and energy, as I found out while talking to a few students who passed the final exams (only 15% pass on their first try). Which practical course I will take is randomly decided. My skills so far are the absolute basics of Java and C programming. I know the different data types and how to handle them, objects, pointers, thread programming, etc. All of that is on a very low level, though. My question now is, what language should I start seriously practicing? Java: I did my first GUIs with this language. I'm familiar with Eclipse but I need a project to work on (which I don't have) to really keep me pushing. Besides that, I don't think it would help me if I have to do C in a year. C: As with Java, I can't think of a personal project to keep me working and keep me interested in programming. If I get assigned to Java in a year, this wouldn't give me any advantages either, would it? (No objects, etc.) Objective-C: I recently came up with this idea. I have a Mac; I'm not really familiar with Xcode but I have one or two personal projects I'd like to work on. Further, I would be working with objects (as in Java) and C language constructs which would both be great for this practical course in a year. What do you think I should begin with? Should I just stick to Java and hope for the best, force myself through C or start (nearly) completely from the beginning with Objective C? Maybe you folks could give me some good advice that would stop me from switching from one language to the next?

• How can I edit/create new launcher items in Unity?

  - by Ike

  Will Unity allow making custom launcher icons from .desktop files or via menu editing system? (Right now the launcher doesn't give the option to "keep in launcher" on all programs. For some programs I use, I have to make custom launchers or .desktop files. For instance, daily blender builds are generally just folders with an executable. In basic gnome or kde, I can make a new menu entry with the menu editing system. Then, I can also add it to docky either from the menu or by dragging a .desktop file to it. Unity launcher doesn't support drag and drop, so thats not a bug or anything, but when i open a .desktop file, it has unpredictable results. Most time it will not have"keep in launcher". Sometime it will have a pinnable item without the .desktop's icon, and if i pin the item to the launcher, it will not call upon the program again after closing it. I've also gotten it to just work with a .desktop file for "celtx".

• The cost of Programmer Team Clustering

  - by MarkPearl

  I recently was involved in a conversation about the productivity of programmers and the seemingly wide range in abilities that different programmers have in this industry. Some of the comments made were reiterated a few days later when I came across a chapter in Code Complete (v2) where it says "In programming specifically, many studies have shown order-of-magnitude differences in the quality of the programs written, the sizes of the programs written, and the productivity of programmers". In line with this is another comment presented by Code Complete when discussing teams - "Good programmers tend to cluster, as do bad programmers". This is something I can personally relate to. I have come across some really good and bad programmers and 99% of the time it turns out the team they work in is the same - really good or really bad. When I have found a mismatch, it hasn't stayed that way for long - the person has moved on, or the team has ejected the individual. Keeping this in mind I would like to comment on the risks an organization faces when forcing teams to remain together regardless of the mix. When you have the situation where someone is not willing to be part of the team but still wants to get a pay check at the end of each month, it presents some interesting challenges and hard decisions to make. First of all, when this occurs you need to give them an opportunity to change - for someone to change, they need to know what the problem is and what is expected. It is unreasonable to expect someone to change but have not indicated what they need to change and the consequences of not changing. If after a reasonable time of an individual being aware of the problem and not making an effort to improve you need to do two things... Follow through with the consequences of not changing. Consider the impact that this behaviour will have on the rest of the team. What is the cost of not following through with the consequences? If there is no follow through, it is often an indication to the individual that they can continue their behaviour. Why should they change if you don't care enough to keep your end of the agreement? In many ways I think it is very similar to the "Broken Windows" principles – if you allow the windows to break and don’t fix them, more will get broken. What is the cost of keeping them on? When keeping a disruptive influence in a team you risk loosing the good in the team. As Code Complete says, good and bad programmers tend to cluster - they have a tendency to keep this balance - if you are not going to help keep the balance they will. The cost of not removing a disruptive influence is that the good in the team will eventually help you maintain the clustering themselves by leaving.

  Need to quickly know, or be reminded about, how to create network configuration profiles in Oracle Solaris 11 ?How to configure VLANS ?How to manipulate Zones ?How to use ZFS shadow migration ? To have those answers, and many more, neatly in front of you, we created this cheat sheet (pdf). Originally developed by Joerg Moellenkamp, the author of the very popular blog c0t0d0s0.org, and of the "Less Known Solaris Features", some more people at Oracle jumped in and added more and more very useful commands to it. And it may keep evolving, so keep checking ! The link to it can also be found on our new Oracle Solaris Evaluation page.

• Can I run Ubuntu Live from a USB flash-drive without destroying the data on it?

  - by Lucian

  I already have a number of files on a flash drive (8 gb) that I would prefer to keep, but I would like to try Ubuntu even if merely for the aesthetics. I use Windows XP. I know that it's definitely possible to run Ubuntu from a bootable drive like my flash drive to try Ubuntu but I would much rather keep my files intact not only on my flash drive but also my hard drive, if that's possible. I also want to know if it's entirely possible that while running Ubuntu from the USB if I can switch back to Windows while my computer is still on. If I'm missing something, please let me know. I'm very grateful for any assistance in this matter.

• What is the best database design for managing historical information? [closed]

  - by Emmad Kareem

  Say you have a Person table with columns such as: ID, FirstName, LastName, BirthCountry, ...etc. And you want to keep track of changes on such a table. For example, the user may want to see previous names of a person or previous addresses, etc. The normalized way is to keep names in separate table, addresses in a separate table,...etc. and the main person table will contain only the information that you are not interested in monitoring changes for (such information will be updated in place). The problem I see here, aside form the coding hassle due to the extensive number of joins required in a real-life situation, is that I have never seen this type of design in any real application (maybe because most did not provide this feature!). So, is there a better way to design this? Thanks.

• Map, Set use cases in a general web app

  - by user2541902

  I am currently working on my own Java web app (to be shown in interview to get a Java job). So I've not worked on Java in professional environment, so no guidance. I have database, entity classes, JPA relationships. Use cases are like, user has albums, album has pics, user has locations, location has co-ordinates etc. I used List (ArrayList) everywhere. I can do anything with List and DB, get some entry, find etc. For example, I will keep the list of users in List, then use queries to get some entry (why would I keep them in Map with id/email as key?). I know very well the working and features, implementing classes of Map, Set. I can use them for solving some algorithm, processing some data etc. In interviews, I get asked have you worked with these, where have you used them etc. So, Please tell me cases where they should be used (DB or any popular real use case).

• IIS 6 nested virtual directory redirection

  - by threedaysatsea

  We're running IIS 6 on a WinServer2k3 box and we're having some trouble with the following problem: E-mails were sent out to users asking them to go to the following URL: alias.contoso.com/directory2/view.aspx?queryparam1=no&queryparam2=blue However, the URLS are actually supposed to be: server.contoso.com/directory2/view.aspx?queryparam1=no&queryparam2=blue It's too late to recall all of the e-mails, and we'd like to redirect traffic to make this as seamless as possible for our users. The real problem here is that the server (server.contoso.com) is hosting the alias (alias.contoso.com) as a redirect thusly, and the existing redirect we need to keep functional: Default Web Site (server.contoso.com) --Directory1 --Directory2 --Directory3 Redirection to Directory3 (alias.contoso.com) --Essentially alias.contoso.com will take the user to server.contoso.com/Directory3 Is there any way to host a separate redirect inside of the existing redirect? We need to keep alias.contoso.com taking the user to server.contoso.com/Directory3 but also make alias.contoso.com/directory2/view.aspx?queryparam1=no&queryparam2=blue point to server.contoso.com/directory2/view.aspx?queryparam1=no&queryparam2=blue Any tips? Is this even possible?

• Should I use the factory design pattern for every class?

  - by Frog

  I've been writing a website in PHP. As the code becomes more complex, I keep finding problems that can be solved using the factory design pattern. For example: I've a got a class Page which has subclasses HTMLPage, XMLPage, etc. Depending on some input I need to return an object of either one of these classes. I use the factory design pattern to do this. But as I encounter this problem in more classes, I keep having to change code which still initiates an object using its constructor. So now I'm wondering: is it a good idea to change all code so that it uses the factory design pattern? Or are there big drawbacks? I'm currently in a position to change this, so your answers would be really helpful.

• How to conduct A/B split testing with AdSense?

  - by None

  Ok so I have decided to A/B test my AdSense ads. I have run a few tests, but I don't know what conclusion to draw and how to keep track of things. Some specific questions: If I have 2 test units, 1 wins. I test that with a new and so on. How do I find if say the fifth one did better than the first one? How do I keep track of things? Do I let the variables independent of each other, because they certainly are not. In real life, font size can affect CTR even if the colors are different. I can test blue color with red color, and then test Arial font with Georgia, but how do I know which combination is the best? This would result in way too many test units. I tried Googling a lot, but I could not find answers to these questions.
