• how to refactor tricky logic involving consecutive sets?

  - by keruilin

  The rule at work here is that users can be awarded badges for a streak of 10, 20, and 30. If the user has a streak over 30, such as 40 or 50, then the logic must be that it only awards a 10-streak badge for 40 and a 20-streak badge for 50, and so on. def check_win_streak(streak) badge = 10 while badge < badge::MAX_STREAK_BADGE_SIZE do # MAX_STREAK_BADGE_SIZE = 30 if streak < badge then break end if (streak % badge == 0) then award_streak_badge(badge) end badge += 10 end end

• web service for business logic or data access layer

  - by luiscarlosch

  This post http://www.theserverside.net/tt/articles/showarticle.tss?id=Top5WSMistakes encourages me to create the web service for business logic layer but many people use it in the data access layer. I want to create a project where i want to access the same data repository from a desktop application, website and a cell phone. What would you recommend me? Is there any case it may be a good idea implement web services to both layers? thanks.

• logic question about factorials

  - by Syom

  I have a problem and can't solve it alone. My teacher gives me one logic task today, and i'm sure you can help me. How can I count the number of zeroes at the end of factorial(41). (on paper) I understand that it has nothing to do with programing, but I'm sure programers can help me. Thanks in advance.

• Is the separation of program logic and presentation layer going too far?

  - by Timwi

  In a Drupal programming guide, I noticed this sentence: The theme hook receives the total number of votes and the number of votes for just that item, but the template wants to display a percentage. That kind of work shouldn't be done in a template; instead, the math is performed here. The math necessary to calculate a percentage from a total and a number is (number/total)*100. Is this application of two basic arithmetic operators within a presentation layer already too much? Is the maintenance of the entire system severely compromised by this amount of mathematics? The WPF (Windows Presentation Framework) and its UI mark-up language, XAML, seem to go to similar extremes. If you try to so much as add two numbers in the View (the presentation layer), you have committed a cardinal sin. Consequently, XAML has no operators for any arithmetic whatsoever. Is this ultra-strict separation really the holy grail of programming? What are the significant gains to be had from taking the separation to such extremes?

• Phone number in meta description bad or good for local rankings NAP

  - by bybe

  Once again I'm at it with increasing people's local rankings and I've learnt so much about local rankings in the past 2 weeks it feels like my brain is gonna pop anyway, question is fairly simple for someone who engages in local rankings and I appreciate the question may be a little guess work but isn't SEO mostly guessing anyway? From what I've read and learned that Google works of a system called nap for local rankings (With many other factors but this question is purely based on NAP). For people who care about local rankings NAP stands for Name of Business / Address of Business / Phone Number for Business. Now what what I've read you don't need the whole NAP to be on one website, a P or just a N can help towards your local rankings. It's believed that NAP rewards more than just P and N for example but knowing Google they might have a diversity checker which is my concern what your get to in a moment. Now of course sites weight differently where your business is posted, it's certainly going to be more credible if your NAP details are on your national phone book than say a blog site, so taking in this consideration too. Pure Guess (Not apart of the question but none the less makes a good read on my belief). Now my guess work would make me believe that the formula would look something like (N)+(A)+(P)x(T) So (N)name would be 1 or 0 to indicate present or not So (A)dress would be 1 or 0 to indicate present or not So (P)hone would be 1 or 0 to indicate present or not So (T)rust would be 1-100 to indicate level of trust So a phone number appearing on youtube might look something like 0+0+1x95= 95 and a NAP appearing on your national phone book might look something like 1+1+1x100= 300 Please note that I'm not saying this is the sole factor and I'm sure its way more complex that this with things like other factors on the page, off the page (Reviews, Links, Clicks) and so on but its still a contributor). The Question My question is fairly simple and I'd imagine hard to impossible to have an actual definite answer to this but maybe someone has seen official wording else where on this, is it bad to include address or phone number in the Meta Description? The reason I ask is that one of my competitors has these elements in the meta descriptions and their local rankings are absolutely superb, the problem I have with this is scrap bot sites like 'Similar Too' 'Seo Rankings' and 1,000's of the other scrap box networks that scrap site and then make urls with your site information are mostly limited to your meta description what this means that your phone number, address and sometimes even your company name if the domain is exact will appear as AP, and even NAP on thousands of websites. So, is it a bad strategy to include phone number and address in meta description, everything I read into would suggest its good of course with the downside of maybe lowering quality of description for click thoughts but top rankings would increase this 10 folds anyhow..

• What is the relationship between the business logic layer and the data access layer?

  - by Matt Fenwick

  I'm working on an MVC-ish app (I'm not very experienced with MVC, hence the "-ish"). My model and data access layer are hard to test because they're very tightly coupled, so I'm trying to uncouple them. What is the nature of the relationship between them? Should just the model know about the DAL? Should just the DAL know about the model? Or should both the model and the DAL be listeners of the other? In my specific case, it's: a web application the model is client-side (javascript) the data is accessed from the back-end using Ajax persistence/back-end is currently PHP/MySQL, but may have to switch to Python/GoogleDataStore on the GAE

• What is the difference between "someValuesFrom" and "allValuesFrom"?

  - by ahmed

  In descriptive logic, what is the difference between "someValuesFrom" and "allValuesFrom"? In other words, the difference between (limited existential quantification) and (value restriction). For example, consider this picture: I have used the photoshop because I can't write some symbols. Is there any way to simplify the concept of somevaluefrom and allvaluesfrom?

• What's wrong with my logic here?

  - by stu

  In java they say don't concatenate Strings, instead you should make a stringbuffer and keep adding to that and then when you're all done, use toString() to get a String object out of it. Here's what I don't get. They say do this for performance reasons, because concatenating strings makes lots of temporary objects. But if the goal was performance, then you'd use a language like C/C++ or assembly. The argument for using java is that it is a lot cheaper to buy a faster processor than it is to pay a senior programmer to write fast efficient code. So on the one hand, you're supposed let the hardware take care of the inefficiencies, but on the other hand, you're supposed to use stringbuffers to make java more efficient. While I see that you can do both, use java and stringbuffers, my question is where is the flaw in the logic that you either use a faster chip or you spent extra time writing more efficient software.

• High level programming logic, design, pattern

  - by Muhammad Shahzad

  I have been doing programming from last 7 years, getting better and better, but still i think that am lacking something. I have been doing work in JOOMLA, MAGENTO, WP, Custom PHP, Opencart, laravel, codeignitor. Sometimes i need to design logic for a huge database application, in the applications we need nesting loops and queries, although i follow OOPS standards, ORM etc, still i feel i need more robust coding designs. I need to know how can i improve these things, so that code remain neat, efficient and faster. Also how big webapps like facebook twitter tests there code speed? How high level programmers choose design patterns. If you can help me find something useful with examples?

• C# logic order and compiler behavior

  - by Terrapin

  In C#, (and feel free to answer for other languages), what order does the runtime evaluate a logic statement? Example: DataTable myDt = new DataTable(); if (myDt != null && myDt.Rows.Count > 0) { //do some stuff with myDt } Which statement does the runtime evaluate first - myDt != null or: myDt.Rows.Count > 0 ? Is there a time when the compiler would ever evaluate the statement backwards? Perhaps when an "OR" operator is involved?

• What is more interesting or powerful: Curry/Mercury/Lambda-Prolog/your suggestion.

  - by Bubba88

  Hi! I would like to ask you about what formal system could be more interesting to implement from scratch/reverse engineer. I've looked through some existing and rather open (open in the sense of free/open-source) projects of logical/declarative programming systems. I've decided to make up something similar in my free time, or at least to catch the general idea of implementation. It would be great if some of these systems would provide most of the expressive power and conciseness of modern academic investigations in logic and it's relation with computational models. What would you recommend to study at least at the conceptual level? For example, Lambda-Prolog is interesting particularly because it allows for higher order relations, but AFAIK (I might really be mistaken :)) is based on intuitionist logic and therefore lack the excluded-middle principle; that's generally a disatvantage for me.. I would also welcome any suggestions about modern logical programming systems which are less popular but more expressive/powerful. I guess, this question will need refactoring, but thank you in advance! :)

• ASP.NET Meta Keywords and Description

  - by Ben Griswold

  Some of the ASP.NET 4 improvements around SEO are neat.  The ASP.NET 4 Page.MetaKeywords and Page.MetaDescription properties, for example, are a welcomed change.  There’s nothing earth-shattering going on here – you can now set these meta tags via your Master page’s code behind rather than relying on updates to your markup alone.  It isn’t difficult to manage meta keywords and descriptions without these ASP.NET 4 properties but I still appreciate the attention SEO is getting.  It’s nice to get gentle reminder via new coding features that some of the more subtle aspects of one’s application deserve thought and attention too.  For the record, this is how I currently manage my meta: <meta name="keywords"     content="<%= Html.Encode(ConfigurationManager.AppSettings["Meta.Keywords"]) %>" /> <meta name="description"     content="<%= Html.Encode(ConfigurationManager.AppSettings["Meta.Description"]) %>" /> All Master pages assume the same keywords and description values as defined by the application settings.  Nothing fancy. Nothing dynamic. But it’s manageable.  It works, but I’m looking forward to the new way in ASP.NET 4.

• Separation of business logic

  - by bruno

  When I was optimizing my architecture of our applications in our website, I came to a problem that I don't know the best solution for. Now at the moment we have a small dll based on this structure: Database <-> DAL <-> BLL the Dal uses Business Objects to pass to the BLL that will pass it to the applications that uses this dll. Only the BLL is public so any application that includes this dll, can see the bll. In the beginning, this was a good solution for our company. But when we are adding more and more applications on that Dll, the bigger the Bll is getting. Now we dont want that some applications can see Bll-logic from other applications. Now I don't know what the best solution is for that. The first thing I thought was, move and separate the bll to other dll's which i can include in my application. But then must the Dal be public, so the other dll's can get the data... and that I seems like a good solution. My other solution, is just to separate the bll in different namespaces, and just include only the namespaces you need in the applications. But in this solution, you can get directly access to other bll's if you want. So I'm asking for your opinions.

• Help with a logic problem

  - by Stradigos

  I'm having a great deal of difficulty trying to figure out the logic behind this problem. I have developed everything else, but I really could use some help, any sort of help, on the part I'm stuck on. Back story: *A group of actors waits in a circle. They "count off" by various amounts. The last few to audition are thought to have the best chance of getting the parts and becoming stars. Instead of actors having names, they are identified by numbers. The "Audition Order" in the table tells, reading left-to-right, the "names" of the actors who will be auditioned in the order they will perform.* Sample output: etc, all the way up to 10. What I have so far: using System; using System.Collections; using System.Text; namespace The_Last_Survivor { class Program { static void Main(string[] args) { //Declare Variables int NumOfActors = 0; System.DateTime dt = System.DateTime.Now; int interval = 3; ArrayList Ring = new ArrayList(10); //Header Console.Out.WriteLine("Actors\tNumber\tOrder"); //Add Actors for (int x = 1; x < 11; x++) { NumOfActors++; Ring.Insert((x - 1), new Actor(x)); foreach (Actor i in Ring) { Console.Out.WriteLine("{0}\t{1}\t{2}", NumOfActors, i, i.Order(interval, x)); } Console.Out.WriteLine("\n"); } Console.In.Read(); } public class Actor { //Variables protected int Number; //Constructor public Actor(int num) { Number = num; } //Order in circle public string Order(int inter, int num) { //Variable string result = ""; ArrayList myArray = new ArrayList(num); //Filling Array for (int i = 0; i < num; i++) myArray.Add(i + 1); //Formula foreach (int element in myArray) { if (element == inter) { result += String.Format(" {0}", element); myArray.RemoveAt(element); } } return result; } //String override public override string ToString() { return String.Format("{0}", Number); } } } } The part I'm stuck on is getting some math going that does this: Can anyone offer some guidance and/or sample code?

• ActiveRecord Logic Challenge - Smart Ways to Use AR Timestamp

  - by keruilin

  My question is somewhat specific to my app's issue, but the answer should be instructive in terms of use cases for association logic and the record timestamp. I have an NBA pick 'em game where I want to award badges for picking x number of games in a row correctly -- 10, 20, 30. Here are the models, attributes, and associations in-play: User id Pick id result # (values can be 'W', 'L', 'T', or nil. nil means hasn't resolved yet.) resolved # (values can be true, false, or nil.) game_time created_at *Note: There are cases where a pick's result field and resolved field will always be nil. Perhaps the game was cancelled. Badge id Award id user_id badge_id created_at User has many awards. User has many picks. Pick belongs to user. Badge has many awards. Award belongs to user. Award belongs to badge. One of the important rules here to capture in the code is that while a user can be awarded multiple streak badges (e.g., a user can win multiple 10-streak badges), the user CAN'T be awarded another badge for consecutive winning picks that were previously granted an award badge. One way to think of this is that all the dates of the winning picks must come after the date that the streak badge was awarded. For example, let's pretend that a user made 13 winning picks from May 5 to May 8, with the 10th winning pick occurring on May 7, and the last 3 on May 8. The user would be awarded a 10-streak badge on May 7. Now if the user makes another winning pick on May 9, the code must recognize that the user only has a streak of 4 winning picks, not 14, because the user already received an award for the first 10. Now let's assume that the user makes 6 more winning picks. In this case, the code must recognize that all winning picks since May 5 are eligible for a 20-streak badge award, and make the award. Another important rule is that when looking at a winning streak, we don't care about the game time, but rather when the pick was made (created_at). For example, let's say that Team A plays Team B on Sat. And Team C plays Team D on Sun. If the user picks Team C to beat Team D on Thurs, and Team A to beat Team C on Fri, and Team A wins on Sat, but Team C loses on Sun, then the user has a losing streak of 1. So when must the streak-check kick-in? As soon as a pick is a win. If it's a loss or tie, no point in checking. One more note: if the pick is not resolved (false) and the result is nil, that means the game was postponed and must be factored out. With all that said, what is the most efficient, effective and lean way to determine whether a user has a 10-, 20- or 30-win streak?

• PHP + Code Igniter Timecode Calculation Logic Error

  - by Tim

  Hello everyone, I have what I suspect to be a logic problem with an algorithm I am using to work with Video timecode in PHP. All help is appreciated. The Objective Well basically I want to work with timecode and perform calculations For those not familiar with timecode it looks like this 01:10:58:12 or HH:MM:SS:FF 'AKA' HOURS:MINUTES:SECONDS:FRAMES I have used the script from HERE to help me with working with this format. The Problem Now can i just say that this script works!!! Timecode calculations (in this case additions) are being performed correctly. However this script continually throws the following errors, yet still produces the correct output when I try and do the following calculation 00:01:26:00 + 00:02:00:12 The errors from this calculation are shown below A PHP Error was encountered Severity: Notice Message: Undefined index: key Filename: staff/tools.php Line Number: 169 A PHP Error was encountered Severity: Notice Message: Undefined index: key Filename: staff/tools.php Line Number: 169 Line Number 169 is in the parseInput() function // feed it into the tc array $i=0; foreach ($tc AS $key=>$value) { if ( is_numeric($array["$i"]) ) { $tc["$key"]= $array["$i"]; if ($tc["$key"] < 10 && $tc["$key"] > 0 && strlen($tc['key'])==1 ) $tc["$key"]= "0".$tc["$key"]; } $i++; } return $tc; Now I should also mention that the number of times the above error is thrown depends on what I am calculating 00:00:00:00 + 00:00:00:00 returns no errors. 01:01:01:01 + 02:02:02:02 produces 8 of the above errors.

• XSLT 1.0 help with recursion logic

  Hello guys, I'm having troubles with the logic and would apprecite any help/tips. I have <Deposits> elements and <Receipts> elements. However there isn't any identification what receipt was paid toward what deposit. I am trying to update the <Deposits> elements with the following attributes: @DueAmont - the amount that is still due to pay @Status - whether it's paid, outstanding (partly paid) or due @ReceiptDate - the latest receipt's date that was paid towards this deposit Every deposit could be paid with one or more receipts.

If there are 3 deposits: 500 100 450 That are paid with the following receipts: 200 100 250 I want to get the following info: Deposit 1 is fully paid (status=paid, dueAmount=0, receiptNum=3.
