readability

问题 I have very little experience in web development, so this may be a very basic question. It's just, from the limited experience I do have (a little PHP, and a little Ruby on Rails), it seems that the way dynamically generated HTML is formatted just "doesn't matter"; it ends up ugly, with weird indentation, and nobody cares because that isn't what the users sees. Unless, of course, the user is a developer, or even just someone who's curious to look at a little HTML to try and learn something.

问题 Guice's stack traces can get so verbose that they are very painful to read. Here's an example: 1) No implementation for java.util.Set<com.mydomain.myapp.android.activities.catbrowser.generalizedbrowser.listview.helpers.databaseitem.itemmanipulators.ItemManipulator<com.mydomain.myapp.flash.Cat>> annotated with @com.google.inject.assistedinject.Assisted(value=) was bound. while locating java.util.Set<com.mydomain.myapp.android.activities.catbrowser.generalizedbrowser.listview.helpers

问题 I'm maintaining some code and have found the following pattern a lot: var isMale = (row["Gender"].ToString() == "M") ? true : false; instead of this: var isMale = (row["Gender"].ToString() == "M"); Is there any reason why anyone would do this? Does anyone think the former is more readable or clearer? Is there some sort of old C "gotcha" that this is a hold-over from? 回答1: A valid reason? No. It's usually produced by people who don't really understand that a condition is also in itself an

问题 I prefer to use long identifiers to keep my code semantically clear, but in the case of repeated references to the same identifier, I'd like for it to "get out of the way" in the current scope. Take this example in Python: def define_many_mappings_1(self): self.define_bidirectional_parameter_mapping("status", "current_status") self.define_bidirectional_parameter_mapping("id", "unique_id") self.define_bidirectional_parameter_mapping("location", "coordinates") #etc... Let's assume that I really

问题 I noticed that even when paying respect to the single responsibility principle of OOD, sometimes classes still grow large. Sometimes accessing member variables directly in methods feels like having global state, and a lot of stuff exists in the current scope. Just by looking at the method currently working in, it is not possible anymore to determine where invidiual variables accessible in the current scope come from. When working together with a friend lately, I realized I write much more

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed last year . I am not sure what the best practices are here, but I often see abbreviated variable names especially when the scope is small. So (to use simple Ruby examples) instead of def add_location(name, coordinates) , I see things like def add_loc(name, coord) —and I might even see

问题 I have some css styles with background colors, borders, etc... like this: .bg-red { background-color:red; } .bg-blue { background-color:blue; } /*more background colors*/ .border-red { background-color:red; } .border-blue { background-color:blue; } /*more border colors*/ /*Like this i also have foreground color, border thickness, border style, transition/hover styles (specially for button hover) */ Like this i can style for example buttons. example <button class="fg-green bg-white border

问题 When querying the database with the same query but different parameters, is it better to: do it in a single using, or to create two separate queries? Example of a single using: using (SqlCommand addProduct = new SqlCommand(@"insert into [Products].[Products] ([Name], [Price]) values (@name, @price)", sqlConnection)) { // Insert the first product. addProduct.Parameters.AddWithValue("@name", "Product 1"); addProduct.Parameters.AddWithValue("@price", 41F); int countAffectedRows = addProduct

问题 I am using iOS 4.3 & was wondering if there is any way that I can access the Safari's "Reader" feature through which webpages are removed of ads & other riff raff & the content takes the center stage. If one opens any article in Safari (on say Wikipedia website), then a "Reader" button appears on the URL bar. Clicking on it presents a new window presenting the content beautifully. How can I leverage this this functionality in iOS through UIWebView ? PS: I know there is something called
