• Javascript new object (function ) vs inline invocation

  - by Sheldon Ross

  Is there any considerations to determine which is better practice for creating an object with private members? var object = new function () { var private = "private variable"; return { method : function () { ..dosomething with private; } } } VS var object = function () { ... }(); Basically what is the difference between using NEW here, and just invoking the function immediately after we define it?

• Is pdf virus proof? [closed]

  - by Jonathan

  I am creating a secure document portal for a client. One of the things that they are worried about is having someone upload a document with a virus. One solution that might work is to enforce that they only upload pdf files. My question is two fold: Most importantly, is a pdf document virus proof? How can you determine in a *nix environment that a file is a pdf, besides just looking at the extension. Thanks! Jonathan

• Example compilers

  - by saf

  I'm searching for the source code of a compiler capable of creating Win32 programs from an input program in a programming language (It doesn't matter which, maybe the simpler the better) Yet I can't find anything right for me and huge compilers like GCC make me extremely confused as they have so many features that I don't know where to start. Is there an OpenSource Win32 micro-compiler for some programming language out there I could take a look at?

• How do I recover from an unchecked exception?

  - by erickson

  Unchecked exceptions are alright if you want to handle every failure the same way, for example by logging it and skipping to the next request, displaying a message to the user and handling the next event, etc. If this is my use case, all I have to do is catch some general exception type at a high level in my system, and handle everything the same way. But I want to recover from specific problems, and I'm not sure the best way to approach it with unchecked exceptions. Here is a concrete example. Suppose I have a web application, built using Struts2 and Hibernate. If an exception bubbles up to my "action", I log it, and display a pretty apology to the user. But one of the functions of my web application is creating new user accounts, that require a unique user name. If a user picks a name that already exists, Hibernate throws an org.hibernate.exception.ConstraintViolationException (an unchecked exception) down in the guts of my system. I'd really like to recover from this particular problem by asking the user to choose another user name, rather than giving them the same "we logged your problem but for now you're hosed" message. Here are a few points to consider: There a lot of people creating accounts simultaneously. I don't want to lock the whole user table between a "SELECT" to see if the name exists and an "INSERT" if it doesn't. In the case of relational databases, there might be some tricks to work around this, but what I'm really interested in is the general case where pre-checking for an exception won't work because of a fundamental race condition. Same thing could apply to looking for a file on the file system, etc. Given my CTO's propensity for drive-by management induced by reading technology columns in "Inc.", I need a layer of indirection around the persistence mechanism so that I can throw out Hibernate and use Kodo, or whatever, without changing anything except the lowest layer of persistence code. As a matter of fact, there are several such layers of abstraction in my system. How can I prevent them from leaking in spite of unchecked exceptions? One of the declaimed weaknesses of checked exceptions is having to "handle" them in every call on the stack—either by declaring that a calling method throws them, or by catching them and handling them. Handling them often means wrapping them in another checked exception of a type appropriate to the level of abstraction. So, for example, in checked-exception land, a file-system–based implementation of my UserRegistry might catch IOException, while a database implementation would catch SQLException, but both would throw a UserNotFoundException that hides the underlying implementation. How do I take advantage of unchecked exceptions, sparing myself of the burden of this wrapping at each layer, without leaking implementation details?

• OpenRasta overwriting Content-Length header in HEAD responses

  - by Dave Nichol

  I'm creating a pretty simple HTTP service using OpenRasta. For HEAD requests, the HTTP 1.1 spec states that HEAD requests should have the Content-Length set to "the size of the entity-body that would have been sent had the request been a GET" (section 14.13). However, OpenRasta apparently sees that the response body is empty and automatically sets the Content-Length header to "0". What is the recommended way to override this behavior? Thanks-
