naming

问题 I'm in a situation where a module I'm using has a function whose name is exactly the same as one in my own module. When I try to call the function in my module (OO Perl, so $self->function ) it's calling the function from the other module instead. I've already got around it by renaming my function but as a matter of interest, is there any way of explicitly calling the function from my module? edit: this is essentially what I'm doing package Provider::WTO; use base qw(Provider); # Provider

问题 I'm trying to use a Performance Counter do determine how many bytes my application has sent or received. I followed the suggested solution found here: Calculating Bandwidth, but the instance of my application doesn’t show up in the “.NET CLR Networking” category. Exception message: "Instance 'ApplicationName[8824]' does not exist in the specified Category" (I have added <performanceCounters enabled="true"/> in my App.config and it still it cannot be found after some networking activities) So

问题 Larvel uses snake_case for table columns name. How to overwrite this assumption in a way the following getter works? public function getFooBarAttribute() { return json_decode($this->attributes['fooBar'], true); } 回答1: I need to first caveat this answer with the following: I haven't tested this code; secondly I have never had a requirement to use this. With that said, there is a static property available on eloquent models: /** * Indicates whether attributes are snake cased on arrays. * * @var

问题 in oCn? What is the rule? using(SqlConnection oCn = new SqlConnection( "Server=(local);Database=Pubs;User ID=TestUser1;Password=foo1;")) { oCn.Open(); ... } I found that type of naming in this article http://msdn.microsoft.com/en-us/magazine/cc163799.aspx 回答1: An entirely obsolete way of saying that "Cn" is an * o *bject. 回答2: I am afraid that it is a remainder of some hungarian dialect notation for an object. In C# and .NET I consider this useless. EDIT By the way I consider Hungarian

问题 Related to this question, what is the best practice for naming a mutex? I realize this may vary with OS and even with version (esp for Windows), so please specify platform in answering. My interest is in Win XP and Vista. 回答1: A really safe name for a global mutex is <a description> + <a GUID> : MyApp Single Instance Mutex : {c96f7db4-d743-4718-bef0-8533a198bcca} By using a name like this there is absolutely no chance someone else will use the same mutex name as your mutex. Sniffing around

问题 Most programming code, I imagine is written in English. But I'm curious how people are handling the issue of naming herein. A lot of programming is done within some bussiness domain, usually with well established terms for certain procedures, items. I'm from Denmark for instance, and something I work a lot with has a term called "indblikskode", which sort of translates to "insight code". So, do I use the line "string indblikskode = ..." in the C# code for some web service related to this? Or

问题 I just discovered that i can give a name to For and While statements. I understand that it is useful if you want to break or continue a specific loop. But why should i give a name to an If?? It looks useless name: if(true){ //do something } This compiles without problems 回答1: If you have a code block with a name, you can use break to exit it, that is the use I have found for naming blocks. name: if(true) { // do something if(/* condition */) { break name; } // do more } it also works without

问题 Here are a list of aliases in C# (compliments of What is the difference between String and string in C#?): object: System.Object string: System.String bool: System.Boolean byte: System.Byte sbyte: System.SByte short: System.Int16 ushort: System.UInt16 int: System.Int32 uint: System.UInt32 long: System.Int64 ulong: System.UInt64 float: System.Single double: System.Double decimal: System.Decimal char: System.Char I can see bool through char being lowercase aliases, because they are primitive

问题 What do you call these : body > p + p in a CSS selector? Are they: Relational operators Position-based criteria Something else? I just have no idea what to call them. Is there an official name? (And, also, are there official names for a b c in a b c, d e f and a in a b c ?) 回答1: According to http://www.w3.org/TR/CSS2/selector.html#selector-syntax they are called "combinators". Thanks to Duncan Babbage for pointing out there are (or were) only three of them: space character = descendant > =

问题 My full variable name is Unique Code, however I want this variable to be "ucode"-ish. So what would be correct concidering Java naming conventions? ucode uCode UCode 回答1: See the coding conventions. For variables, camel case is recommended. Re. the naming, I would have thought uniqueCode would be the most logical choice (I'm aware that wasn't in your list of choices). Any uCode variant looks like an abbreviation of unicode to me, and I would regard it as misleading. The above isn't an
