I agree with everyone else that you should try as hard as you can to separate the HTML/XHTML markup from the application logic. However, sometimes you do need to generate HTML/XHTML in the application logic for various reasons.

In Python, indentation is a semantic element as well as providing visual grouping for readability.
Both space and tab can indicate indentation. This is unfortunate, because:

among editors and IDEs and is often
configurable (and often configured).

I need to support exact phrases (enclosed in quotes) in an otherwise space-separated list of terms.

There are 3 major ways of dealing with XML, in general: dom, sax, and xpath.

The sax model is great if you only care about a few tags,... |
Recently I was talking to a co-worker about C++ and lamented that there was no way to take a string with the name of a class field and extract the field with that name; in other words, it lacks reflection. He gave me a baffled look and asked when anyone would ever need to do such a thing.

One of the primary reasons to implement an application as a web application is that you get automatic upgrades for free. Why would users be getting prompted for upgrades on a web app?

Well, it really depends on your business model but for a lot of applications the SaaS model can end up biting you. It's great for a lot of things but for some larger applications the users are not investing as significant amount up front and could possibly move to something else before you've made any money.

If you're providing a hosted solution, I wouldn't bother. Let the upgrade happen silently (perhaps with a notice that you did it). If you're selling an application that's hosted on their servers, let the upgrade decision be made by a single owner, not every user of the app. |
Siebel gives an extensive rundown (for simple cases anyway) of possible sources of leaks, and there aren't any of those here. Both <code>value</code> and <code>factor</code> are evaluated only once and in order, and <code>rem</code> doesn't have any side effects.

Your macro looks fine to me. I don't know what a leaky macro is, but yours is pretty straightforward and doesn't require any gensyms. As far as if this is "good" Lisp, my rule of thumb is to use a macro only when a function won't do, and in this case a function can be used in place of your macro. However, if this solut... |

Sometimes by the time you "complete functionality" using copy and paste code, you've come to a point that it is maimed and mangled enough that any attempt at refactoring will actually take much, much longer than refactoring it at the point where it was obvious.

Your best bet IMO would be to use javascript to look for a cookie named "origReferrer" or something like that and if that cookie doesn't exist you should create one (with an expiry of ~24hours) and fill it with the current referrer.

A couple of things lead to me to question if it was true. One was the app that I use to author the installer, [InstallAware][1], only pulls in the .NET 2.0 Framework if I add the Report Viewer 2008 runtime.

The main gotcha I see is that you're not handling any errors: .login() and .sendmail() both have documented exceptions that they can throw, and it seems like .connect() must have some way to indicate that it was unable to connect - probably an exception thrown by the underlying socket code.
