I think the key thing with VAR is to only use it where appropriate i.e. when doing things in Linq that it facilitates (and probably in other cases).
If you've *got* a type for something in the then you should use it - not to do so is simple laziness (as opposed to creative laziness which is generally to be encourag... |
Rob Walker is right: the problem isn't specified in enough detail. Considering just parsers (and ignoring the question of whether they perform validation), there are two main flavors: tree-based—think DOM—and streaming/event-based—think [SAX](http://en.wikipedia.org/wiki/SAX) (push) and [StAX](http://en.wikipedia.org/w... |
One specific case where var is difficult: offline code reviews, especially the ones done on paper.
You can't rely on mouse-overs for that. |
Timezone lookup from latitude longitude |

Is there any library (or even better, web service) available which can convert from a latitude/longitude into a time zone? |
I still think var can make code more readable in some cases. If I have a Customer class with an Orders property, and I want to assign that to a variable, I will just do this:
var orders = cust.Orders;
I don't care if Customer.Orders is `IEnumerable<Order>`, `ObservableCollection<Order>` or `BindingList<Order>... |

The best way IMHO is to clearly outline exactly what the cost of implementing the new features will be. "It would be nice if" really starts to dwindle when the user starts to see the cost of such additions.
Disagreeing with the customer about a feature usually gets you nowhere. If you blatently say NO to them th... |

You can intercept the memory allocation functions and see if there are some memory zones not freed upon program exit (though it is not suitable for *all* the applications).

All of them should be sufficient for that. Unless you need some library that is only available in one language, I'd let personal preference guide me. |

From svrist's link:

According to the [filed bug report][1] there is a work-around:

It's worth mentioning that it is a feature though, not a bug. The above work-around just disables the feature.

If you're looking for a scripting language that will play well with Java, you might want to look at Groovy.

You cannot handle just feature creep - you need to organise your whole development process in an proper way.

What do you mean by backend and and frontend?
If you mean using Java for the admin side of your site and PHP for the part that the public will see then there is nothing stopping you.
The implications are that you will have to maintain two applications in different languages. |
This isn't a direct answer to the question, because I feel it's already been answered above, however, one of the books that definitely had an impact on how I code is [Code Reading, Volume 1: The Open Source Perspective][1].

Try removing the IP restrictions for Relaying in the SMTP server, and opening it up to all relays. If it works when this is set, then you know that the problem has to do with the original restrictions. In this case, it may be a DNS issue, or perhaps you had the wrong IP address listed. |

My gut reaction is "why not?" A database is going to provide a framework for storing information, with all of the input/output/optimization functions provided in a documented format.

The database won't help you much in dealing with the image data itself, but anything that manages a bunch of images is going to have meta-data about the images that you'll be dealing with. Depending on the meta-data and what you want to do with it, a database can be quite helpful indeed with that.
