just unzip Portable Firefox into a folder on your desktop and use

I agree with #3 and #4, but the first two are implementation problems.
Tidy can ensure that HTML is well-formed, and well-formed HTML can
(and should) be swept for naughty bits relatively easily.

Rick: The forum bits of JournURL do all of that, and I've waffled
back-and-forth about releasing it as a stand-alone app over the years.
But that would leave me doing a number of things:

(1) Radically cleaning up the admin UI.

(2) Figuring out an installation procedure for mere mortals.

(3) Deciding whether or not to strip out all of the non-forum stuff.

(4) Removing dependencies on various bits of code that I don't have
the right to redistribute, or can't redistribute without running into
GPL issues. (jTidy, for example.)

Finding the time and will for all of that can be kinda difficult. :D

Massimo: Just to let you know... I was playing around with your CFC,
and noticed that on some images (usually horizontally oriented ones),
bufferedCrop() would throw an "outside of raster" error. I was able to
fix it by modifying the code to check for crop operations that exceed
the height of the image.

With that said, thanks for putting the code out there.

Re: XML/RSS Search Feed

[Roger B.]

When publishing an XML document, your job is to provide the results in
a known document format (RSS or something else entirely) and let them
know how your URIs work. It can get a bit more complicated than that
in some cases, but not for simple search engine queries.

> ...or could they just use inline frames that point to templates on our site?

I think you need to clarify exactly what you're trying to do.

(1) Are you trying to provide search results that can be consumed by
other machines/servers, stored and/or manipulated, and then displayed
to that machine's user(s)? If so, then XML is what you're after.

(2) Are you trying to provide search results directly to end-users,
without any storage or customization on the part of "foreign" sites?
If so, then just output plain ol' HTML. You can deliver it via IFRAME
or Javascript.

Jim: That's a matter of perspective. Some people love Dave Winer's
approach to spec-writing, and some people absolutely *loathe* it. I'm
gonna guess you're in the latter group. :D

> - Convert a null into an empty value: .

I can't say conclusively, but I would opt for the first or third choice. 

If you can afford the ambiguity, the first is the best... most
implementations (including mine) will interpret an empty  as
a zero-length string, but at least it leaves open the possibility for
other implementations.

> Any idea about what's "right"?

Technically, XML-RPC dates have no timezone. Apps are expected to set
timezones in another method, or within another param in the current
method.

In practice, my (de)serializer respects the above... but the instant
it returns the value to my main code, I promptly assume that it is UTC
and go from there. :-)

> +) String formatting seems... odd.  The spec claims that only ampersands and
> less-than signs should be escaped - is this right?  Not even greater-than

Basically, it's saying "do what you would normally do to escape any
off-limits XML characters". Technically, greater-than signs don't need
to be escaped as long as you escape any less-thans, but most of us do
it anyway, just to be safe.

Probably the easiest thing to do is just wrap strings in ,
although there may be an oddball deserializer out there that will
barf.

> If you have some time I'd much appreciate you going over my XMLRPC
> implementation to see if it measures up.

I went ahead and set up a little debugger for you. Just go here:

http://agincourtmedia.com/xmlrpc/testxmlrpc.cfm

and enter any of your serialized chunks into the form. It will wrap
whatever you input in a method/param, deserialize it, and CFDUMP the
results.

I don't claim that my (de)serializer is any kind of benchmark, but
it'll at least let you know if you're heading down the right path.

You were probably one search term away... that's how it always works

Re: WDDX Replacement Attempt (was RE: Ajax and CFCs)

[Roger B.]

Jim: Any reason not to go with the prior art and just use (or extend,
if necessary) XML-RPC?

XML-RPC parsers are everywhere, so it's pretty much the no-brainer
default option for passing around programmatic data. In fact, that was
one of the big points made when Jeremy Allaire and I were discussing
his idea of embedding raw data in RSS feeds a couple years ago... not
only is it more lightweight than WDDX or SOAP, there's virtually no
language or environment that doesn't already support it. That kind of
ubiquity is hard to ignore.

RSS/Atom Feed CFC 2.0x

[Roger B.]

After two (very, very long) years of argument and debate, the Atom 1.0
IETF specification is an official Proposed Standard. Broad deployment
will now begin in earnest, so if you work with syndication feeds, it's
time for some upgrades.

Rssatom.cfc is a feed normalizer... it takes in RSS 1.0, RSS 2.0, Atom
0.3, Atom 1.0, and "Atomic RSS" feeds and spits out a generic data
structure. Great pains have been taken to make it spec-compliant where
appropriate, and common practice compliant where the specs are silent.

The original 2.0 release and basic documentation is here:

http://admin.mxblogspace.journurl.com/?mode=article&entry=8425

and the latest release (2.04) is here:

http://admin.mxblogspace.journurl.com/?mode=article&entry=8874

Oh, and a quick public service announement. *Please* be careful when
displaying third-party syndicated content on your site... the
opportunities for cross-site attack are many, and are too often
overlooked by folks who think that this stuff is as simple as an HTTP
request and a pass through an XML parser.

Ray: It's easy to miss if you're not a serious iPod user. My iPod
mostly sits there until I take a road trip or something... it's not a

you go, then the simple machinery of podcasting seems like magic.

It's an unwired, hands- and eyes-free version of the web for joggers,
travellers, and anyone else whose lives afford them the opportunity to
spend lots of time wearing earbuds. Not my thing, but if had a

Re: OT: RSS and Languages

[Roger B.]

Isaac: It isn't. In RSS 2.0, rss:language is a channel-level element
and that's it.

Don't be fooled by the versioning. RSS 1.0 and 2.0 have nothing to do
with one another... they're completely different forks of the 0.91
format, created and maintained by different entities.

> Does anybody else have any more insight on this?

If you're intent upon having item-level language declarations, you've
got a few choices:

(1) Use dc:language... see the Dubline Core definition for details.

(2) Apply standard xml:lang attributes as appropriate to RSS 2.0
elements. Note that the spec doesn't make any explicit reference to or
use of xml:lang.

(3) Use Atom 1.0, where the spec *does* explicitly support xml:lang.

Of the few consuming apps that are language-aware, you're most likely
to see support for (1) and (3). I'd probably go with (1), since people
are still debugging their Atom 1.0 parsers right now.

templates.

NOTE: I was working (with input from Dave Winer) on an ID3 extension
for RSS 2.0, but got sidetracked and haven't returned to the idea. The
more you dig into ID3, the uglier it gets, and I just haven't been
motivated to fiddle with it lately.

Of course, some folks don't want a hosted environment, and
Jake/Ray/etc. are definitely cheaper... I can give people free blogs,
but I can't give 'em much in the way of free upload space, lest I trip
over the shoestrings that hold my budget together.

Re: CF Blog shootout

[Roger B.]

BlogCFM: Has a way to go, but can probably catch up.

BlogCFC: Basic, but does what it does in a solid, well-considered
fashion. The defaults are particularly well-chosen, for example.
Honestly, its greatest weakness has nothing to do with Ray's code...
it's just that BlogCFC invites tinkering, and uninitiated tinkerers
give severe migraines to those who spend their time maintaining
aggregators. :D

BlogFusion: If I were going to use one of the three for a blog, I'd
probably use Jake's. The feature set gets it closer to the bare
minimum that I would expect from a tool. The major caveat is that,
assuming he gets his Trackback autodisco fixed, BF users are sitting
ducks for 100%-CPU-utilizing, 1000-pings-an-hour spam strikes. IP
blocking is utterly useless when facing a wave of zombies, and if they
can autodiscover you, look out. (He said, from bitter experience.)

If I bundle an L-GPL'd spellchecker with my CMS, I have to make the
source of the spellchecker available if I make any changes. But the
whole point of the L-GPL is that the controls stop there... the rest
of the CMS is licensed in whatever fashion I please.

Mike: For anti-spam, try the SpamBayes plugin for Outlook. Unlike the
Bayesian filters in something like Thunderbird, SB sorts spam into
"Junk" and "Possible Junk" folders. That means you virtually never
have to worry about false-positives, because anything borderline will
fall into the small, easily scanned "Possible" list.

That could certainly be part of it. Then there's the fact that it's an
ActiveX component, which is the kiss of death in the
post-XPSP2/Firefox world. And the fact that it doesn't appear to do
XHTML doesn't help.

On an intranet, without any web wonks to service, it could be a great
solution. But it probably isn't going to be anyone's first suggestion
in a general "what's a good WYSIWYG?" discussion.

Matthew: jTidy will handle ill-formed documents... JournURL uses it

puzzling out which of the gazillion methods you need to call to get
the results you're after.

Suggestions:

jTidy.setNumEntities(true);
jTidy.setXHTML(true);
jTidy.setXmlOut(true);
jTidy.setForceOutput(true);

That last one is crucial, and caused me weeks of headaches before I

Re: Tree Traversal / Storage Algorithm

[Roger B.]

Jeff: I never had any "old CS days" to forget, but the best approach
to tree-building that I've found is a single id/parentid query wed to
a set of parallel structures that are connected by reference.


FETCH YOUR IDs and PARENTIDs


















You can recursively walk stcTree to display it graphically, or use
node.parentid and node.id to quickly crawl up the stcFlat to create a
breadcrumb trail. And unlike other methods, it also gives you an easy
way to snap a branch off the tree and do something with it.

css - height 100% - i'd like to kill the crack-addicts who wrote the w3c box model

[Roger B.]

 > I
 > remembered somebody'd already solved this particular problem before:
 >
 >  http://www.redmelon.net/tstme/3cols2/ 


Keith: That example conveniently sums up why I'm abandoning CSS
positioning after a couple years of work in that area. CSS-P is so
incredibly fragile that any unpredictable event can mangle it and
render the page unusable.

For example, I dropped a large photo into that layout, and instead of
stretching the center column to accommodate it, Firefox let the image
overlap the right column. IE fared even worse, effectively blowing up
in my face... the content in the left and right columns jumped into
the center column and joined the flow.

But it gets worse. Just as a goof, I removed the image, leaving an
empty  element to the center column. Firefox didn't even blink,
but IE suddenly allowed the left column's content to leap into the
center column and actually overlap it. A single empty paragraph was
all it took to break the layout.

If you're designing for controlled content, CSS-P can be effective.
But if you're designing for content generated by mere mortals, it's a
disaster waiting to happen in every browser I've ever seen.

RE: CF vs ASP.NET! GET YOUR FRESH POPCORRRRN!!

[Roger B.]

> ASP.NET is taking market away from CF!

I doubt you can substantiate that. CF's market share appears to have shrunk
from the old 2.0 and 3.0 days, but there's been a lot more going on than
ASP.NET. In fact, ASP.NET is a minor blip on CF's radar when compared to the
giant swarm of open-source development platforms like PHP.

Why? Perhaps people know something about their businesses or clients that
you don't.

(1) Anyone who is price-conscious won't be using ASP.NET. They'll be using
PHP or Ruby on a Linux box.

(2) Anyone who is forced to pay an outrageous price for CF (those in need of
Enterprise features) is already paying much, much more for the development
and hosting of a large, complicated, and clustered application.

Isaac,

Unless you've an RDF fan, all you need is at:

That's also the first hit on Google for "RSS", so it's pretty easy to find.

If you *do* love RDF, then you need to look at:

http://web.resource.org/rss/1.0/

To find out what's wrong with your feed (no matter what version), run it
through a validator:

Netscape abandoned RSS many years ago, so there is no official home for
it... in the meantime, several competing groups have laid claim to the name.
All you need to figure out is if you want to do straight XML or RDF/XML and
proceed accordingly.

RE: The point of XML for us in CF?

[Roger B.]

I use XML so extensively at this point that answering this question is kinda
difficult... kinda like, "Any other reasons to own a car beyond driving to
work?" :D

- Supplying content to client applications... Newzcrawler lets me know when
my blog detects a new, incoming link by checking my CF-generated
referrers.xml file.

- Remote Procedure Calls... I can post to my blog via a third-party
application using XML-RPC.

- On a related note, I use a standardized XML file to tell those third-party
applications what APIs that I support.

- Storing content... JournURL keeps the actual text of a user's entries in a
WDDX packet, with the database serving as a SQL-friendly index.

- Storing non-essential metadata... since I've already got that WDDX packet
sitting there, I can stick any old data in it. No need to add tables or
columns to the database, unless the new data is important stuff that needs
to be indexed.

- When I want to tell an author that I've linked to her, I automatically
send an XML "ping" to her server. Similarly, other folks can send me XML
notifications which will magically appear as annotations on my blog.

- Configuration files... I find simple XML easier to edit than .INI-style
stuff.

Joshua,

between larger corporate customers and small developers/businesses. They
want to keep prices as low as possible for the latter in order to build the
market, and then make most of their money by hitting up the former for extra
cash.

The alternative would be arcane per-seat licensing and so on, which is
annoying to the user and a pain to audit for the server provider. Or they
could charge everyone a middle-ground price that drives away small
developers, a very unappealing thought.

RE: XML Best Practices - Resources

[Roger B.]

> What's the best way to store phone numbers in XML?
> 1234567890
>  or maybe...
> 

Brad,

I can't tell you what's best, but I can tell you how I would approach it.
Proceed only after you have procured several thousand grains of salt.

Personally, I'd start by clarifying what I'm describing. A phone has
attributes like "white", "hasCord", and so on. What you're actually dealing
with isn't a phone but a phone number, which has attributes like "mobile"
and "extension 312". The number itself is the thing that interests us.

So here's where I'd end up:

1234567890

However, looking at that, I see I'm asserting that "1234567890" is an
instance of a phone. And we've already established that it isn't. To clarify
*that*, I would end up with:


  1234567890


...or...

1234567890

Choosing between them would be a matter of considering how detailed I want
to be in compiling this info. The latter will work fine, nine times out of
ten. But there are edge cases... for example, what if I can be reached at a
single, physical phone via two distinct numbers with distinctive rings? It
might be useful to know that those numbers are related:


  1234567890
  0987654321


  5498763210


At that point, I'd probably call it "good enough". But that's good enough
for me, not anyone else.

There's nothing ridiculous about the FB learning curve... FB makes instant
sense to many people, and is completely impenetrable to many others. Anyone
who has watched the various FB mailing lists over the years has seen newbies
struggle with simple tasks like framing a Fusebox'd site, not because such
things are actually hard to do, but because FB can be conceptually confusing
to folks who are accustomed to EPIAI (Each Page Is An Island) web
development.

Folks have different backgrounds and make different intuitive leaps. That's
just the way it is.

Philip,

I'm no FB evangelist... people should use whatever works for them, IMO. But
there are a couple things in your comment that don't make sense to me.

(1) FB2 places no particular limits on the locations of your individual
fuses. In my case, each JournURL community is an independent instance of an
FB2-ish app, but all instances share dsp_s, act_s, qry_s, custom tags, and
CFCs that are stored in centralized locations.

(2) Ignoring any potential architectural issues, the problem you're
describing could have been solved with an automation app like AutoMate
(http://www.unisyn.com/automate/). One click (or a scheduler) will copy
files across directories and FTP them to the appropriate remote locations.
Would have been a whole lot simpler than scrapping most of the code and
starting from scratch.

RE: Macromedia Updates Contribute

[Roger B.]

I had pretty much made up my mind about product activation long before
Macromedia decided to include it in Contribute.

I'm willing to accept it in my OS (XP)... I'm willing to accept it in unique
tools that lack real competition (Flash, if it comes to that)... but I'll
never accept it when there is a viable, non-activation alternative. I'm
still using Office 2000, and will never upgrade to Office XP, for example.
And while it probably wouldn't have anyway, Contribute 2 will never see the
light of day on my desktop.

CF, Dates, and WDDX

[Roger B.]

Maybe I'm overlooking something obvious, but CF's internal date handling
seems a bit odd to me. Anyone else noticed anything along these lines?

Basically, while playing around with manually constructed WDDX packets, I
noticed that the UTC offset returned by GetTimeZoneInfo() reflects the
Daylight Savings status of the server, but the WDDX serialization process
doesn't. I went into this in more detail in my blog:

http://journurl.com/mxblogspace/users/admin/?mode=article&entry=388

Don't get me wrong... it works once you understand it. But man, I spent some
serious head-scratching time while trying to sort out what CFMX was doing.
And since the same thing seems to happen in CF5, I can't even blame it on
MX.

Dave,

You *have* seen the worst of FB, haven't you? :) I have little in the
way of three line CF files, myself... I think that's going overboard.

To broaden my example, that query file I mentioned *does* run a
query... but then it checks to see if any records were returned. If
not, it constructs a special, substitute query. Then it loads a series
of associated WDDX files from the file server, does a little string
manipulation, and merges them into the query in question.

SPs aren't a useful option in my particular app, but I'm all for your
argument that people should use them as much as possible. But even if
the example were using an SP instead of a CF-generated query, the rest
of that work would still need doing. And Fusebox provides a nice way
to access that work without having every other app on the server
re-invent the wheel.

Why wouldn't you simply pass that server level variable into the tag

Dave,

Agreed. I should state for the record that I'm not of the FB3,
drag-and-drop, reuse-the-same-fuses-across-a-dozen-applications
school. When I talk about code modularization and reuse in Fusebox,
I'm talking specifically about having an app serve as a sort of
inter-application "web service" via the custom tag interface.

>I don't find this level of linkage

Let me give you a concrete example with which I'm intimately familiar:

Let's say you have a forum app. One of its tasks is to display a list
of recent discussions... let's give that task a name like
"showtopics". Showtopics' work is broken down into a query, the
creation of a thread structure, and then the layout of the page.

Now, if I want to display a list of recent forum discussions on my
site's front page, I *could* recreate the query call, the threading
code, and wedge it into the code that creates that front page. Or I
could simply call my fusebox as a custom tag and say, "Hey, use your
pre-existing code to feed me the query results and that structure...
but leave off your presentation stuff, 'cause I'll do that myself."

Call me crazy, but when I have a chance to separate data from
presentation, I take it. :)

>I should note that I'm not a fan of Fusebox.

I know, and I'm not a fan of *all* of it... the official version,
anyway. But I like some of the core ideas a great deal.

In my apps, the form variable would "win" the spot in the attributes

I think those two issues are apples and oranges. In the case of the
request scope and custom tags, I agree with you. A custom tag
shouldn't be "reaching out" to grab its data from global variables...
that data should be explicitly sent into the tag.

But in the case of the formurl2attributes thing, nothing is
breaking... attributes is as valid an input scope as form or url.
There's no "reaching out" involved.

Dave,

Okay... but that's not a description of a typical Fusebox application,
where one of the primary ideas is avoiding tightly linked modules. One
set of sufficiently abstract queries can power an application and
simultaneously expose that application's data or services to other
apps via the custom tag interface... and any optimization of those
queries (or whatever) benefits not just the core app, but everything
that calls it.

Re: Fusebox - opinions?

[Roger B.]

>1. Pros? Cons? Opinions? I've generally only seen good
>feedback, but I thought I'd see...

I can't recommend Fusebox at this point... the official version is a study
in overkill that tries to define the "right way" for your apps to be built.
Some folks love that aspect of it, of course, but I have no patience for the
whole thing.

OTOH, I highly recommend using a fusebox. The fundamental idea is very
useful. To me, the key is to just look at the core concept:













Routing all requests through a central hub creates a handy, self-documenting
"map" of an application's flow, allows modularization without tons of nested
includes, and provides a mechanism for turning basic security (or whatever)
features on and off on a per-request basis without a lot of conditional or
"hidden" code.

Everything else is just extra, and may be completely unnecessary in any
given situation. You don't need to move incoming variables into a unified
scope, you don't need to nest fuseboxes, you don't need to wrap the whole
thing in cf_bodycontent/cfsavecontent and delay rendering, or anything
else... there's a ton of benefit to be had from the simple beauty of a
CFSWITCH.

Not that I'm discouraging use of the extras... there are all kinds of
interesting things you can do, above and beyond the basics. But you don't
have to use Fusebox and its trappings to make use of a fusebox.

I encountered a similar problem with a Fusebox'd app I'm working on.
In non-FB terms, the solution was to:

(1) Have the login page look for the existence of incoming form and
url variables

(2) Serialize them with WDDX, and stuff them in a temporary session
var along with a reference to the URL they were intended for.

(3) Continue with the login process.

(4) After verifying the user's identity, CFLOCATION back to the
original destination page, deserialize anything in the temp variable,
and proceed with processing.

Erik,

That's one of CF's "garbage errors"... it can indicate any number of
potential problems, and doesn't give you any useful feedback you can
use to hunt down the real error.

Along with the other suggestions you've received, I'd recommend
looking for any use of the Duplicate() function in your code. At one
point, I had an app that used Duplicate() to move Session scoped
queries-within-nested-structures into the Request scope, and it would
consistently bomb with the error you received.

The solution was to toss out Duplicate() until CF5 and use WDDX to
move between scopes instead.

Rick,

In theory, Duplicate() gets around CF's tendency to pass nested
structures as references rather than copies. Without it, you may end
up corrupting memory just as quickly as you would have without
bothering with the request scope in the first place.

OTOH, some folks' CF boxes can't abide Duplicate(), consistently
returning a never-ending cavalcade of obscure errors. (For me, it
seems to only happen with small queries stored in session variables.)
The alternatives become rather ugly at that point... you're  basically

Mark,

It really depends on the "source" of the breadcrumbs. For example,
will the user be drilling down through physical directories, or
through categories defined in a database? Directory-based breadcrumb
trails are pretty simple to implement... just parse the appropriate
CGI variable and you're done. 

Category-based trails are more complicated, with various trade-offs
involved. You can use recursion to walk the hierarchy, with the
obvious performance hit. You can use nested sets, but suffer the added
layer of complexity. Or you can do something ugly and have each
category in the DB keep a list of its parents in a dedicated field.

I use session variables. For example:




...various form stuff...





...SQL, logic and so on...




Obviously, you need to lock those session variables or Duplicate()
them into the request scope, but that's the basic idea.

I've seen the applet fail when fed 200KB or more of data. That's one
very big, very complicated tree, though, so such concerns may not be
relevant to your work.

I've been using CS-RCS for a few months now, and am reasonably
satisfied with it... particularly given the price tag. Beware of shell
integration under Windows, though... every time you right-click on any
filesystem object, you end up waiting for RCS to initialize.
