• For structs, do I have to call the constructor explicitly in C#?

  - by Gulshan

  The question is about the structs. When I declare a struct type variable/object (don't know which one suits better) or an array or list of structs, do I have to call the constructor explicitly like objects or just declaring will suffice like variables?

The full code for the History class is here (http://pastebin.com/ZGKK2V84).

• Does using the converting input from HTML forms into htmlentities protect attacks invoving JavaScrip

  - by racl101

  Hi everyone, I was wondering if converting POST input from an HTML form into html entities, (via the PHP function htmlentities() or using the FILTER_SANITIZE_SPECIAL_CHARS constant in tandem with the filter_input() PHP function ), will help defend against any attacks where a user attempts to insert any JavaScript code inside the form field or if there's any other PHP based function or tactic I should employ to create a safe HTML form experience? Sorry for the loaded run-on sentence question but that's the best I could word it in a hurry. Any responses would be greatly appreciated and thanks to all in advance. racl101

• Javascript iFrame Limitations

  - by Matrym

  I know that, for security reasons, javascript can't read the contents of an iframe if it belongs to a different domain. This makes sense, given that the entire page could be an iframe with snooping scripts outside of the frame. The question is - are there equal limitations in the other direction? Can javascript within an iframe (from a different domain) read and manipulate the dom in its parent window? Thanks!

• Does access/write to Boolean object needs synchronization

  - by Suraj Chandran

  This may seem a very silly question. Consider this: I have a simple Boolean object with a getter and a setter. Now both of the methods are called from a lot of threads very frequently. Do I need to have a synchronization for this boolean? Also are Boolean assignments atomic operations?

• method names with fluent interface

  - by deamon

  I have a Permissions class with methods in fluent style like this: somePermissions.setRead(true).setWrite(false).setExecute(true) The question is, whether I should name these methods set{Property} or only {property}. The latter would look like this: somePermissions.read(true).write(false).execute(true) If I look at these methods separately I would expect that read reads something, but on the other hand it is closer to the intention to have something like named paramaters like in Scala: Permission(read=true, write=false, execute=true)

• URL Slugs: Redirects or 404s?

  - by anonymous coward

  Some sites, like here at SO, allow 'bogus' slugs in the URL. Before implementing URL slugs on my site, I have a question of 'best practices'... Given a structure like example.com/123/article-slug-here/, if my site allows bogus slugs by querying on the ID - Should I ... just do a redirect to the appropriate/canonical URL (verifying the slug, and redirecting in case of a mismatch)? -or- return a 404, since technically example.com/123/this-article-s-u-x doesn't exist?

• What's the difference between isPrototypeOf and intanceof in Javascript?

  - by Steffen Heil

  Hi In some of my own older code, I use the following: Object.prototype.instanceOf = function( iface ) { return iface.prototype.isPrototypeOf( this ); }; Then I do (for example) [].instanceOf( Array ) This works, but it seems the following would do the same: [] instanceof Array Now, surly this is only a very simple example. My question therefor is: Is a instanceof b ALWAYS the same as b.prototype.isPrototypeOf(a) ? Regards, Steffen
