The player might run on a cheap laptop or might run on a Raspberry Pi. I need to make sure the slicer will work on any OS and that people don't need to install too much extra stuff to make it work.

23,319,746 | 0 | decorator design pattern violating is-a relationship <p>I have recently started studying about decorator design pattern but I have a query. Decorators implement the same interface as the Component they are trying to decorate. Doesn't this violate the is-a relationship. Moreover since the decorator has the component (through composition) , why is it really required for the decorator to implement the same component interface which the concrete component implements.?</p> <p>Going through the decorator design pattern on Headfirst, it gives me a feeling that decorators can directly implement the component. There is no need to have an abstract class / interface for decorator. </p> <p>I am worries that this could really be a dumb question but help would allow me to have a strong foundation. </p> |

8,336,241 | 0 | <p>Have you thought instead about using two separate views instead, and have your conditional logic in your controller determine which view to display.</p> |
3,251,117 | 0 | <p>I'd say follow the <a href="http://en.wikipedia.org/wiki/Single_responsibility_principle" rel="nofollow noreferrer">Single Responsibility Principle</a>.</p> <p>What you have is a SportsCard that does nothing on itself. It's just a data container.</p> <pre><code>class SportsCard { protected $_price; protected $_sport; public function __construct($price, $sport) { $this->_price = $price; $this->_sport = $sport; } public function getPrice() { return $this->_price; } public function getSport() { return $this->_sport; } } </code></pre> <p>The SportsCards have to be stored in a CardBook. If you think about a CardBook, then it doesn't do much, except for storing SportsCards (not Pokemon or Magic The Gathering cards), so let's just make it do that:</p> <pre><code>class CardBook extends SplObjectStorage { public function attach($card) { if ($card instanceof SportsCard) { parent::attach($card); } return $this; } public function detach($card) { parent::detach($card); } } </code></pre> <p>While there is nothing wrong with adding Finder Methods to the SportsCard set, you do not want the finder method's logic inside it as well. It is fine as long as you only have</p> <pre><code>public function findByPrice($min, $max); public function findBySport($sport); </code></pre> <p>But the second you also add</p> <pre><code>public function findByPriceAndSport($sport, $min, $max); </code></pre> <p>you will either duplicate code or iterate over the collection twice. Fortunately, PHP offers an elegant solution for filtering collections with Iterators, so let's put the responsibility for filtering into separate classes as well:</p> <pre><code>abstract class CardBookFilterIterator extends FilterIterator { public function __construct($cardBook) { if ($cardBook instanceof CardBook || $cardBook instanceof self) { parent::__construct($cardBook); } else { throw new InvalidArgumentException( 'Expected CardBook or CardBookFilterIterator'); } } } </code></pre> <p>This class merely makes sure the child classes accept only children of itself or CardBooks. This is important because we are accessing methods from SportsCard in actual filters later and because CardBooks can contain only SportsCards, we make sure the iterated elements provide these methods. But let's look at a concrete Filter:</p> <pre><code>class SportCardsBySportFilter extends CardBookFilterIterator { protected $sport = NULL; public function filterBySport($sport) { $this->_sport = $sport; return $this; } public function accept() { return $this->current()->getSport() === $this->_sport; } } </code></pre> <p>FilterIterators work by extending the class and modifying it's accept() method with custom logic. If the method does not return FALSE, the currently iterated item is allowed to pass the filter. Iterators can be stacked, so you add Filter on Filter on top, each caring only for a single piece of filtering, which makes this very maintainable and extensible. Here is the second filter:</p> <pre><code>class SportCardsByPriceFilter extends CardBookFilterIterator { protected $min; protected $max; public function filterByPrice($min = 0, $max = PHP_INT_MAX) { $this->_min = $min; $this->_max = $max; return $this; } public function accept() { return $this->current()->getPrice() > $this->_min && $this->current()->getPrice() < $this->_max; } } </code></pre> <p>No magic here. Just the accept method and the setter for the criteria. Now, to assemble it:</p> <pre><code>$cardBook = new CardBook; $cardBook->attach(new SportsCard('10', 'Baseball')) ->attach(new SportsCard('40', 'Basketball')) ->attach(new SportsCard('50', 'Soccer')) ->attach(new SportsCard('20', 'Rugby')) ->attach(new SportsCard('30', 'Baseball')); $filteredCardBook = new SportCardsBySportFilter($cardBook); $filteredCardBook->setFilterBySport('Baseball'); $filteredCardBook = new SportCardsByPriceFilter($filteredCardBook); $filteredCardBook->filterByPrice(20); print_r( iterator_to_array($filteredCardBook) ); </code></pre> <p>And this will give:</p> <pre><code>Array ( [4] => SportsCard Object ( [_price:protected] => 30 [_sport:protected] => Baseball ) ) </code></pre> <p>Combining filters from inside the CardBook is a breeze now. No Code duplication or double iteration anymore. Whether you keep the Finder Methods inside the CardBook or in a CardBookFinder that you can pass CardBooks into is up to you.</p> <pre><code>class CardBookFinder { protected $_filterSet; protected $_cardBook; public function __construct(CardBook $cardBook) { $this->_cardBook = $this->_filterSet = $cardBook; } public function getFilterSet() { return $this->_filterSet; } public function resetFilterSet() { return $this->_filterSet = $this->_cardBook; } </code></pre> <p>These methods just make sure you can start new FilterSets and that you have a CardBook inside the Finder before using one of the finder methods:</p> <pre><code> public function findBySport($sport) { $this->_filterSet = new SportCardsBySportFilter($this->getFilterSet()); $this->_filterSet->filterBySport($sport); return $this->_filterSet; } public function findByPrice($min, $max) { $this->_filterSet = new SportCardsByPriceFilter($this->getFilterSet()); $this->_filterSet->filterByPrice(20); return $this->_filterSet; } public function findBySportAndPrice($sport, $min, $max) { $this->findBySport($sport); $this->_filterSet = $this->findByPrice($min, $max); return $this->_filterSet; } public function countBySportAndPrice($sport, $min, $max) { return iterator_count( $this->findBySportAndPrice($sport, $min, $max)); } } </code></pre> <p>And there you go</p> <pre><code>$cardBookFinder = new CardBookFinder($cardBook); echo $cardBookFinder->countBySportAndPrice('Baseball', 20, 100); $cardBookFinder->resetFilterSet(); foreach($cardBookFinder->findBySport('Baseball') as $card) { echo "{$card->getSport()} - {$card->getPrice()}"; } </code></pre> <p>Feel free to adapt and improve for your own CardBook.</p> |

23,258,240 | 0 | <p>I see "duck typing" more as a programming style, whereas "structural typing" is a type system feature.</p> <p>Structural typing refers to the ability of the type system to <strong>express</strong> types that include all values that have certain structural properties.</p> <p>Duck typing refers to writing code that just uses the features of values that it is passed that are actually needed for the job at hand, without imposing any other constraints.</p> <p>So I could <em>use</em> structural types to code in a duck typing style, by formally declaring my "duck types" as structural types. But I could also use structural types <em>without</em> "doing duck typing". For example, if I write interfaces to a bunch of related functions/methods/procedures/predicates/classes/whatever by declaring and naming a common structural type and then using that everywhere, it's very likely that some of the code units don't need <em>all</em> of the features of the structural type, and so I have unnecessarily constrained some of them to reject values on which they could theoretically work correctly.</p> <p>So while I can see how there is common ground, I don't think duck typing subsumes structural typing. The way I think about them, duck typing isn't even a thing that might have been able to subsume structural typing, because they're not the same kind of thing. Thinking of duck typing in dynamic languages as just "implicit, unchecked structural types" is missing something, IMHO. Duck typing is a coding style you choose to use or not, not just a technical feature of a programming language.</p> <p>For example, it's possible to use <code>isinstance</code> checks in Python to fake OO-style "class-or-subclass" type constraints. It's also possible to check for particular attributes and methods, to fake structural type constraints (you could even put the checks in an external function, thus effectively getting a named structural type!). I would claim that neither of these options is exemplifying duck typing (unless the structural types are quite fine grained and kept in close sync with the code checking for them).</p> |

26,883,650 | 0 | Clean HTML table with Reshape2 <p>New user of R. Can't think how to even ask the question. I scraped a webpage for HTML tables. Generally, everything went well, except for one table. Instead of there being 7 separate tables, everything got collapsed into 1 table, with the column name and the value for the first table being two separate columns, and all the other tables being rows. The results is a table with something like this: </p> <pre><code>df <- data.frame(is_employed = c("Hobbies", "Has Previous Experience"), false = c("squash", "false")) </code></pre> <p>Obviously, I need to have the rows (and the column name) in the first column as their own columns, with the item in the second column as their values, preferably with underscores in the columns names. I tried: </p> <pre><code>df <- dcast(df, ~is_employed, value.var = "false") </code></pre> <p>But got an error message. Then I thought to add another column, as such:</p> <pre><code>df2 <- data.frame(number = c(1, 2), is_employed = c("Hobbies", "Has Previous Experience"), false = c("squash", "false")) </code></pre> <p>then I tried </p> <pre><code>df3 <- dcast(df2, number ~is_employed, value.var="false") </code></pre> <p>That placed the values in the first columns as their own columns, but produced two rows (instead of 1), with NAs. I'm sure this is really basic, but I can't figure it out.</p> <p>On edit: I think this gives me what I want, but I'm away from my computer so I can't confirm:</p> <pre><code>library("dplyr") library("tidyr") mat <- as.matrix(df) mat <- rbind(colnames(mat), mat) colnames(mat) <- c("variable", "value") df2 <- as.data.frame(mat) df3 <- df2 %>% mutate(n = 1) %>% spread(variable, value) %>% select(-n) </code></pre> <p>I need to add <code>n</code> or I get NAs, but I don't like it.</p> |

Please run <code>glxinfo</code> as you would your program and post its output here (most likely there's no OpenGL support somewhere in the line). Also execute <code>glxinfo</code> locally, since it is your local machine, that'll do all the OpenGL work.</p> |

7,352,643 | 0 | <p>You can do that using three possibles methods :</p> <ol> <li><p>Design a workflow that is fired on item creation and which is attached to the list</p></li> <li><p>Create an EventReveiver to handle ItemAdded event, and create the SP group</p></li> <li><p>Modify the new form of the list. I don't recommend this way because if customers are created from another place, the logic won't be fired.</p></li> </ol> <p>Another way to solve such problems, but it requires more background of your need, is to split your data into several site collections, one for each customer. Each site collection can have a "Customer" group (maybe created from a site template), which contains the customer. As each site collections have distinct users and groups, it can avoid cross customer data leaking (due to misconfiguration of authorizations).</p> |

Here's the db setup:</p> <pre><code>mysql 4.1.2log charset cp1252 West European (latin1) </code></pre> <p>I'm using PHP but without mbstrings() (though I do no string conversions on this address, just echo).</p> <p>If I changed the mysql charset from cp1252 to UTF-8 and made sure I used things like <code>header( 'Content-Type: text/html; charset=UTF-8' );</code> would that improve my situation? Or, is the data hosed because it was saved in the cp1252 charset and there is nothing I can do? The original database was created in 2002 and has been used/expanded since. We've upgraded servers and re-imported dumps but ashamedly I admit to not giving charsets much thought.</p> <p>If I'm hosed, I'll probably just remove the text in those fields but I'd like to support unicode going forward, so if I issue <code>ALTER database_name DEFAULT CHARACTER SET utf8;</code> will that make sure future multibyte encodings are saved correctly, taking at least storage out of the equation (leaving me to worry about PHP)?</p> <p>Thanks -</p> |
