[Looking for Charlie's main web site?]

How would you run code against multiple CF versions at once using IIS on XP?

Note: This blog post is from 2007. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
If you use IIS on XP, have you ever wished you could put your code in one directory and run it against different versions of CF, easily. In this note, I show you how.

Someone asserted on a list that some code failed as of CF8, but I tested it against 8, 7, 6, and 5, and it worked the same in all. Hearing that, someone else asked, "Charlie, are you running all those on the same machine or on vmware?"

I assume that the reader, like many, is using IIS on XP, which doesn't let you have more than one web site, which might seem to make it impossible, though some may know the tricks I'll mention.

Of course, folks running on Apache, or IIS on Win2k3 or Win2k Server, would just say, "create different web sites, and install each CF version into a different web site".

Fair enough, but how do you solve this using IIS on XP (or Wink2 workstation), if you can't have multiple sites? That's what I explain below.

Before I go on, though, let me make an important for those who may not be aware: you certainly can run multiple versions of CF on a single machine. They each get installed in their own directories, with their own JVM (as of CF6). The challenge is just to avoid port conflicts and external web server conflicts.

But why not just use the built-in web server?

Sure, if you use the built-in web server available in CFMX since 6, then you can indeed run multiple CF versions each with their own web docroot without conflict.

But that's not the point here. That would cause each CF instance to have its own wwwroot, and you'd have to put your code there to run it on that version.

And I have even explained in a recent blog entry that you can get around that using virtual mappings in the JRun web server, pointing to the shared document directory. But sometimes you really want to use IIS for some reason, or you just don't want to have to remember to use the right port and virtual directory name configured for the built-in web server.

But you can have multiple web sites in XP, if you know how...

Yep, some will want to note that you can indeed create multiple web sites in XP, if you use the right tools. I've written about such tools before. It's just that you can't run them at once, so you have to enable/disable each time you want to run the test. To me, that more of a hassle than just doing the one-time configuration which I discuss below.

So how do you configure things using IIS on XP?

OK, I hope I've headed off complaints some may have. Oh, well, I should add one more: what I'm about to show you is definitely not supported by Adobe. Some might even argue against doing it. Certainly, if you have problems with things while trying to work this way, they're going to tell you to use a vanilla setup.

Still, it's worked for me for years. In fact, I first wrote about it in a CFDJ article back in Sep 03 (co-authored with Jeff Houser). That was written in the timeframe of people moving from CF5 to CFMX and wanting to set things up this way, but the concept still applies even for those moving from 7 to 8, or 6 to 7. It also mentioned using the same approach for running against BD as well, which means it would apply also to Railo and Smith, etc.

Finally, since writing that article, I've also realized a few things I could have added to the article, which further motivates me writing this entry.

How I set things up

So, as explained in the article (which shows you the actual steps in IIS), I configure different IIS virtual directories called _cf5, _cf6, _cf7, and _cf8. I set each to points their CFM extension (and related CF ones) to the appropriate web server extension that would be used if I'd configured each server to work with IIS (like C:\CFusion\BIN\ISCF.DLL for 5, C:\CFusionMX\runtime\lib\wsconfig\1\jrun.dll for 6, and so on).

More important, I have them all point at the same, single document root (in my case, c:\inetpub\wwwroot). That allows me to then run code in that single directory against different editions, using a url like http://localhost/_cf5/somefile.cfm, or http://localhost/_cf7/somefile.cfm, or the default http://localhost/somefile.cfm goes against CF8.

Note that you must run the web server connector for each CF edition from CFMX and above, since it only builds those jrun.dlls (I mentioned above) if you do that. See the CF docs ("Installing and Configuring ColdFusion" to learn how to run that, even after CF is installed, if you installed it using the built-in web server instead.

Before you do, though, as explained in the article, be sure to save off the path to the DLL for .cfm file extensions, as running the configuration tool will wipe over the previous path.

Some concerns using the CF Admin in this setup

There's something else to take note of about using the CF Admin (/cfide/administrator/index.cfm) when you set things up this way.

It has to do with whether, when you install each version, you tell CF to install using the built-in web server or using IIS.

In the former case, CF will put that version's CFIDE directory (and all its related files) into the wwwroot for that built-in CF server, such as c:\coldfusion8\wwwroot\ for CF8, or c:\cfusionmx7\wwwroot\ for CF7.

In the latter case (if you tell CF during installation to use IIS), then CF will place those files into the IIS docroot you name. Assuming you would always choose that c:\inetpub\wwwroot directory, that means that its CFIDE directory will be replaced with whatever is the last CF version you install.

And that means that even if using the virtual directories above, they'll all point to the last CFIDE version, which won't work (the CF Admin can only run in the version for which it's created).

Either way, you can solve this by creating yet another virtual directory, for CFIDE, inside the version-specific virtual directories above.

So if during the installation of 6, 7, or 8 you told CF to use the built-in web server, you'd point the new CFIDE virtual directory to the builtin web server's CFIDE. For my _CF6, for instance, I'd create a CFIDE virtual directory within that to point at c:\cfusionmx\wwwroot\CFIDE.

If instead you choose to install each version using IIS, then just as you needed to save off the file extension's path to the web server DLL, you would similarly need to remember before each install to save off a copy the CFIDE directory for the previous release. This is especially key for CF5, since there is no concept of a built-in web server for that.

Back when I installed CFMX 6, before doing so, I copied the CFIDE directory to call it CFIDE5 instead. (Sure, you could do a rename, but only JUST before you installed, in case you need it.) Then I created the CFIDE VD within the _CF5 VD to point to that.

It may be worth noting here that if you do install CF 6/7/8 using the built-in web server initially, and then use the web server configurator tool to then connect them to IIS, that does not move the CFIDE from the built-in web server root to the IIS docroot. So again you will need to point your CFIDE virtual directory to that CFIDE in the built-in web server.

Why not just use the built-in web server for the CF Admin?

Of course, you could just use the built-in web server to access the Admin instead, even if you are otherwise running code via IIS.

And going back to the original writer, you could indeed also do this using VMWARE. (I've written about how versions of it and Virtual PC are now free.) It might be overkill, though. Again, you don't need to worry about running multiple versions of CF on a single server. It's all just about avoiding port conflicts and potential external web server conflicts.

That's what this has been about all about: how to run all your code via IIS against multiple version of CF, all from a single directory.


Did this help you? Let me know. Did I forget something? Got a complaint? (People seem to love that opportunity. Go for it.) I hope it has helped some of you. It's certainly helped me, and others who I've shown it to.

Resources for getting into the Multiserver (multiple instance) implementation of CF

Note: This blog post is from 2007. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
You may have heard of the new Multiserver deployment option that was introduced in CFMX 6.1, also known as "multiple instances". It can bring tremendous performance and reliability improvements, allowing you to segregate apps on a single server either by function, or reliability, and so on. It can also help you manage memory more effectively.

Since many people may only be considering the feature now (either only now moving to 6.1 or 7, or 8), I want to share some resources if you're new to it. (The question came up on a list, and I offered the info there, so thought I'd pass it along here.)

First, there are a couple of articles from that time 6.1 frame:

"Introducing Multiple Server Instances in ColdFusion MX 6.1", by Tim Buntel

"Using Multiple Instances with ColdFusion MX Enterprise 6.1" video (sadly, seems no longer available)

Now, CF7 did introduce the new Instance Manager within the Admin, and that (and instances in general) is covered in the CF manual:

Configuring and Administering ColdFusion MX (Chapter 7, "Using Multiple Server Instances")

Finally, there is also a new Adobe article as of CF7:

Multiple Server Instances using ColdFusion MX 7 Enterprise Edition

(Update: There's also now a CF8 version of that: Multiple server instances using Adobe® ColdFusion® 8 Enterprise Edition. The technical content seems identical, but it appears to have had considerable editorial updating.)

There are certainly other articles folks have done in the CFDJ or at CommunityMX.com, but these should get you started.

Even though it's old news to some, it does seem that like many things, use of instances is something that may have been missed by folks. I've been contemplating a new user group presentation on the topic. Nothing new for CF8, but it seems people are considering things now that they may have ignored when 6, 6.1, or 7 came out (which is why I did my daylong class at CFUnited on what was new in 6 and 7 that folks may have missed).

One last point, if those don't make it: if you're running on Windows, don't try to create an instance with a JVM heap greater than about 1.3 GB. Though Windows should allow 2GB per app, this is just a number many found that beyond which CF won't start. Hope that all helps.

CF8 Admin Changes: A compendium of new/changed features since 7.02

Note: This blog post is from 2007. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.

Are you aware of all the changes that have been made in the CF Admin as of CF8? You may have seen mentions of little changes in CF8 (indeed, I've done a full hour user group talk on hidden gems), and while I mention some changes in the CF8 Admin (as I or others have noticed them), I've not seen any definitive list (from Adobe or the community) of all the changes (small and large) that might have occurred in the CF Admin interface. I figured I'd take up that challenge.

I've gone through and compared the CF Admin between 7.02 admin 8, and found changes that reflect:

  • new major features you've probably heard about (whether to enable "per app settings"; limits on the number of cfthread threads; options to enable/control the new interactive step debugger; support of the new Server monitor; support of per-user access to the Admin and RDS)
  • new minor features you may have missed (options to "disable CFC type check" and "disable access to internal CF java components"; options to limit the number of simultaneous requests from Flash Remoting and web services clients and CFC methods called from a URL; options to set request queue timeouts and set jrun request limits; new options to control mail server authentication; new db drivers; new option to log activity on enterprise databases; new option to perform a validation query when a connection from the pool is first used/reused; new ajax debugger window; ability to pause a scheduled task; 3 new flex-based gateways; minor additions in CAR file creation)
  • realignment of related settings (request tuning settings)
  • renaming of various pages and settings

Here are all the changes I could find, discussed per page:

A. Server Settings Section

Settings Page

  • "Maximum number of simultaneous requests", "Maximum number of report threads", moved to new Request Tuning Page
  • "Maximum size of post data" moved to bottom of this same page
  • New "Enable Per App Settings", "Disable CFC Type Check", "Disable access to internal ColdFusion Java components", and "Watch configuration files for changes" (latter for WebSphere ND)

New Request Tuning Page

  • (Enterprise only) Besides holding the "Maximum number of simultaneous requests" setting (renamed here in CF8 as "Template" requests) moved from the old Settings page, this page now permits setting limits on number of simultaneous requests from flash remoting and web service clients, as well as CFC function requests (not calls to CFC methods from CFML but those made via a URL, such as from a browser or Ajax client, etc, when not using ?wsdl)
  • Besides holding the "Maximum number of simultaneous report threads" setting (renamed here in CF8 to add "simultaneous") moved from the old Settings page, this page also permits setting limits on number of simultaneous CFTHREAD threads
  • (Enterprise only) Page adds 2 new "Queue Timeout" settings
  • (Enterprise only) Page adds 2 new "JRun Master Request" limits

Mail Page

  • New Username and password fields to hold SMTP server authentication info (previously, had to know how to add it to the mail server name using [email protected]:servername in the mail server field). Use of password field offers protection of password from someone watching over your shoulder.
  • New "Connection Timeout" and "Enable SSL Socket connections to mail server" and "Enable TLS connection to mail server" options, each permitting greater security and control over authentication to SMTP servers (particularly Google mail servers)

B. Data & Services Section

Data Sources Page

  • New driver types: "Apache Derby Client", "Apache Derby Embedded", to support the newly available Apache Derby database, and "MySQL 4/5" (in addition to existing MySQL 3) and "PostgreSQL"
  • In "Advanced Settings", new "Log Activity" option (to log database activity to DB) for Enterprise drivers (SQL Server, Oracle, Informix, Sybase, and DB2).
  • In "Advanced Settings", new "Validation Query" option (called when a connection from the pool is reused), available for use with all driver types

Verity K2 Server Page

In "Advanced Settings", new option to enter K2 Admin Username and Password.

C. Debugging & Logging Section

Debugging Output Page

  • Page name changed from just "Debugging Settings" (due to addition of new "Debugger Settings" page listed below).
  • New "Enable AJAX Debug Log Window" option, which allows display of the AJAX debug log window when the cfdebug flag is passed in the URL (also relies on IP address settings to control who sees this)
  • "Enable Debugging" option renamed to "Enable Request Debugging Output"

New Debugger Settings Page

Enable, configure, and control interactive step debugger in Eclipse.

Scheduled Tasks Page

New option to pause a given scheduled task (new button in list of buttons to left of each scheduled task)

Systems Probes Page

Field for "Notifications Sent From" renamed to simply "E-mail".

Code Analyzer Page

Changed to list CF8 tags and functions in "Advanced Options" page.

D. New Server Monitoring Section

(Enterprise only) Offers links to the new Server Monitor and Multiserver Monitor.

E. Event Gateways Section (used to be Enterprise-only)

Gateway Types Page

New Flex-based gateways: "DataManagement", "DataServicesMessaging", "FMS"

F. Security Section

Administrator Page (renamed from "CF Admin Password" page)

(Enterprise ony) Offers new interface to use either a single Admin password (as before), or separate username/password (per authorized admin user, as enabled in new "User Manager" page listed below), or no password required at all

RDS Page (renamed from "RDS Password" page)

(Enterprise only) Offers new interface to use either a single RDS password (as before), or separate username/password (per authorized RDS user, as enabled in new "User Manager" page listed below), or no password required at all

Security Sandbox/Resource Security Page

"CF Tags" and "CF Functions" tabs for adding/editing a sandbox have been changed to list CF8 tags and functions.

New User Manager Page

(Enterprise only) Enables adding users who should be given access to either RDS, CF Admin, or Admin API functionality.

G. (Enterprise only) Packaging & Deployment Section

ColdFusion Archives Page

When adding/editing an archive, the popup window that is shown offers several sections, and the following changes have been observed:
  • Server Settings: "Locking" section has been removed, while "Watcher Settings", "Server Monitor Settings", and "System Probes" have been added
  • New "Web Services" settings page, with provided "pre-restore" and "post-restore" lists

(Enterprise only) J2EE Archives Page

When adding/editing an archive, there is a new "Previous Serial Number (if upgrade)" option.

Where to learn more

To find out more about these changes, see the online help available in the CF Admin, available on each admin page.

Or see the ColdFusion documentation manual, "Administering and Configuring ColdFusion 8", available at CF docs page.

I realize that some reading this will be moving from CF 6, 6.1, 7, or 7.01. I'm afraid I can't detail here all the changes between those releases. I have, however, got a day-long class I offered at CFUnited on "New in CFMX 6/7: What you may have missed", where I do outline changes in each of those releases (and intervening updaters). If you're interested in taking that class, drop me a note or leave a comment here. I am thinking of offering it as an online class (and plan to do the same regarding all changes in CF8--outside of the Admin). Hope all this helps others.

Ever tried the SMS client simulator in CF7 and above? If it fails to launch, here's why

Note: This blog post is from 2007. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
If you never paid much attention to the hubbub about SMS gateways when they came out in CF7, you may have missed that there is an available SMS Test Server and even a client (phone) simulator for working with this feature, both built into CF7 (and 8). You can learn more about these at the URLs below.

But I want to pass on a tip about something that tripped me up when I first tried to "play with" the new phone simulator. I would launch the SMSClient.bat file (in the cfusionmx7/bin directory), and a DOS window would open (and stay open) but I'd never see the simulator.

I finally figured it out: you need to have started the SMS Test Server (done in the "Event Gateways">"Settings" page in the CF Admin).

I also just noticed that there are also a couple of log files created in the same directory as the bat file, which probably would have clued me in. (Even though I've now stopped the test server, I can't get the client to recreate the problem--it now always shows up. I'm sure a restart would solve it and the log may then have told me what to do, but I missed the log before, so I still think this info worth passing along.)

To learn more about the SMS client and server simulators in CF7 (and 8), see:

The CF docs

When pressing enter on an input text field will suddenly not submit the form...sure surprised me!

Note: This blog post is from 2007. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
Most know that a form will submit if you press enter while the cursor focus is on a text field (INPUT TYPE="text"|"radio"|"checkbox"). Some have surely noticed that you don't often even need a submit button, which can be nice when creating some simple interfaces.

But did you know that the submit will not happen if you have two input text fields (and no submit button)? I found this when I had a long-working form of this sort, to which I added a second input field. Suddenly, it stopped submitting on pressing enter. I've tested this in either IE 6 or Firefox 2. I explain the scenario and a solution, below.

The problem

I had a small form on my UGTV recordings list page, which let users enter search criteria. Today, someone asked me to let them indicate how many records to show by default, and when I added a second input box for that, suddenly the submit would not work. (If you look, you'll find the 2nd input field at the bottom of the form, but it doesn't matter. It's within the one form, and the problem happened regardless of where the 2nd field was placed.)

Again, the key is that I have no submit button in this scenario (as it would just look clunky, and is otherwise unnecessary).

Some solutions

So I did some digging and found that indeed others have observed this. One suggestion offered was that you provide a submit button but use CSS to make it invisible. You can't really use "display:none" because then, in IE 6 at least, it still thinks it's not there.

But you can set its height and width to 0 and set the border to none, and it solves the problem:

<input type="submit" style="width: 0px;height: 0px;border: none">

If you'd like some simple code to test with, here you go:

<form action="">
<input name="i1" type="text"/>
<input name="i2" type="text" />
<input type="submit" style="width: 0px;height: 0px;border: none">

If you're curious about the empty action, that just makes the page self-posting. If you're interested in that, or have any comment on that aspect, please see my other blog entry on the subject.

Stuck sending email from a hotel or other blocking environment? Here's a solution when others fail

Note: This blog post is from 2007. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
Hope this may help others. If you're in a situation where you find you can't send email out of your mail client (like Outlook or Thunderbird) because the ISP (or hotel, or client location, for instance) is blocking all outgoing mail (SMTP and the default port of 25), you have a couple of solutions. The common ones (more below) weren't working for me, but I found this gem. Did you know that if you're a gmail account holder, you can setup your mail client to use gmail's mail server to route your outgoing mail through? Yep. It really works, and saved my bacon today! :-)

Important Update

Well, I have to report some news since learning of this and posting about it. It turns out that this approach has the unfortunate side-effect that it makes your note go out as "from" your gmail account--even if you sent it as "from" another account in your mail client. That's a real bummer. Again, perhaps better than nothing, but not what I'd expected. On the surface, it may seem only a nuisance. If you read your gmail mail with your mail client (via POP), then you may not even notice this. But I did notice that the "to" address on replies sent while using this was my gmail address, which is not what I'd expected. And I just checked, and indeed the recipient also sees the email as coming to them "from" your gmail account. If either is a concern, then be aware.

There is a real gotcha, though, if you reply to a list. I had a note from a list that came, as expected, "to" my carehart.org address. When I replied, it would normally go back as "from" that address, which is the address on file at the list. But this change to the gmail address meant the note now went from an address not on the list. Some lists will bounce such notes, so you'll now it's happening (and now you'll understand why). But this list is one where if you send a note from a non-subscribed address, it just ignores it--so the note never got to the list. Only now did I connect the dots. Forewarned is forearmed!

You may not want to *always* do it, but when you're stuck in a hotel and need to get mail out, it's a blessing. I learned of it while traveling at the WebDU conference in Australia and after the conference was staying in a small hotel that was blocking my email. i couldn't get their smtp server address to use instead (more on that below), but using gmail as the smtp server worked!

Here's the blog entry that clued me into the solution. Many thanks to him.

As for how to configure your mail client to this up, the blog entry above gives the basics. You just want to change the SMTP (outbound) setting to use smtp.gmail.com, and port 465 (telling it to use SSL). You also want to configure the login authentication (for sending mail only) to be your gmail account. If you're really not sure how to change your mail settings, this trick may be above your level. But I will point out that Google themselves offer a page of info showing how to configure your mail clients. Just note that it's showing how to setup the client to both send and receive gmail. This trick is JUST about setting up to send email via gmail. Don't delete the incoming (pop) mail settings in your email client for your mail connection.

One last point about the option above: you do need to configure Gmail to permit POP access, as discussed here. But note that you don't HAVE to use pop (meaning a mail client) if you prefer to keep reading gmail via its web interface. If you never connect via pop, it will still be accessible via the web. Also, notice that even if you do collect it via pop (as I do), there's an option there to keep the mail in Gmail's inbox, if you prefer, so it's till always accessible via the web (though the web interface has no way of marking mail you read on your mail client).

Here's one other benefit of this approach of routing email through gmail: have you ever gotten bounces when sending mails because the recipient's mail server says yours is blocked in the "relay blacklist" or similar? This can happen on a hosted mail server because some chucklehead on the same server is involved in spamming, and gets your entire SMTP server detected as a spam source. Using this gmail approach would seem to prevent that (though I suppose some day some idiot will find a way to cause gmail's server to be blacklisted--but they'll certainly be a lot faster to address that than your average hosting provider, I think.)

What are some of the other solutions? Well, here's one entry on some alternatives and following is why they didn't work for me. Still, if you don't use Gmail (or don't want to use the approach above), they're worth noting:

  • Get the hotel (or ISP) to tell you the name of the mail (SMTP) server they prefer you to use, and use THAT in your mail client. Sadly, it's not always possible to get that from the hotel or client staff.
  • Use a webmail interface instead. There's almost always one provided by your email provider, and beyond that there are tools that will serve to do it for you even if yours does not (like www.mail2web.com). But I much prefer to have all my mail (in and out) saved in my mail client, both for archival and searching purposes.
  • Use a 3rd party mail relay service, like smtp.com and smtpanywhere.net. If I hadn't found the gmail solution, I was about to do this. Couldn't find any that are free.
  • Use a tool like JiWire HotSpot Helper, which does mail relay and more (like enabling secure email login and transmission, which is more important than many realize), but it's not free (there is a free trial).
  • Use SSH tunneling, as discussed in a nice write up. Unfortunately, I tried it and my mail host doesn't support it. I've asked them.
  • (Added since original post) Since only port 25 specifically may be blocked for you, you may find that your mail provider offers an alternative port to use to collect email. Mine does not, though as above, I have asked. (This was mentioned in the article I pointed to, but I didn't think to bring it up here in this list. A couple of commenters wanted to stress it as an option, so I'm adding it.)

If there are any other solutions I've missed, please do share. Hope this helps someone.

CF-specific Google search engines (yes, that's plural)

Note: This blog post is from 2007. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
Well, I was tickled to learn about the nifty feature Google's added to let people create "Custom Search Engines" (or CSEs), which can limit searches to a given set of sites, with the intention that this could produce a better topic-specific search. Wouldn't it be nice to search for Ajax and only get sites related to CF implementations and discussions of Ajax (versus other implementations, or the cleaning product?)

So I set off this weekend to create just such a CSE. You can find it here:

Charlie Arehart's CFSearch. It searches over 1,300 CF-related sites.

Update: Here's an update: if you're interested in adding this search to your Firefox search bar (in the top right corner of the browser), you can, via a simple Firefox add-on. I've blogged about it here. Now, back to the original blog entry content...

And then there were two...

But just as I was about to excitedly announce it to the world yesterday, I happened upon an entry in the google Co-op forums related to CSEs when I saw a post from good ol' Joshua Cyr . He was announcing (in October) to a forum there that he'd created one (http://www.cfhunt.com) and would they consider listing it on the featured sites page.

Imagine my dismay. He'd beaten me to the punch. Now, I was about to let it go, and just concede that really only one needed to exist, so I didn't even announce mine yesterday.

And then there were three...

But then today on a CFML list someone else (Jeff Gladnick) announced that he had created one (http://www.cfsearchengine.com). While it was ironic that yet another person had the bright idea just this weekend (it seems), it also struck me as tragic.

Each of us has spent the time gathering over 100 URLs to be searched in our CF-specific CSEs. I know it took me a few hours. I poured through about 300 of the top URLs coming back from a Google search for "ColdFusion". I have docs pages, blog pages, user group pages, CF product pages, and more. And I even went so far as to use a special feature in the CSE setup called contexts, where you can subset URLs such as by those topics (docs, blogs, etc.) Of course, then I saw so had Joshua! :-)

Turns out there are several...

So I'm here to serve several purposes. I want to point out all the CF-related CSEs I've found or been told about (yes, there are more), and hope to warn off any who would create another. We've got enough. They are listed below in descending order of their current count of sites indexed (viewable on their respective CSE home page). A couple have those other domain names by which you can find them:

Michael and Judith Dinowitz's (2544 sites):


Charlie Arehart's (1338 sites)


Jeff Gladnick's (829 sites):


or via


Joshua Cyr's (236 sites)


or via


Adam Howitt's (38 sites):


or via


Pete Freitag's (29 sites):


Mark Gaulin's (11 sites):


Ray Camden's (3 sites):


And anonymous (2 sites):


If you know of any others, drop me a comment below.

And if you're thinking of creating another...

But let me say that if you find for some reason that one of the CSEs doesn't search one or more sites you think it should, you don't need to go create another one (I don't think that was the case with any of us). Instead, you can choose to volunteer to contribute to any of the existing ones.

Who's should be crowned the ultimate one? Well, I think Joshua's the oldest, and it has the most sites indexed (for now). There's no real harm in the others remaining. Heck, like so many things on the web, sometimes dupes just mean better chances of someone finding a thing.

Why isn't it easier to find all existing ones?

I will say that I've complained to the folks at Google to have them add a means to search for existing ones. That would help both those looking for one, and those thinking of creating a new one. I looked on that featured examples page, and seeing none for CF, thought I'd do the CF community a favor. Now, instead, I see that others are reaching the same conclusions.

I will also add that the folks at Google told me (on the forum, in reply to my question) that s short-term solution is for one to use a particular set of google keywords that might help find CSEs on a specific topic:

site:google.com inurl:coop/cse topic

Sadly, that's imperfect, as it found only 3 of the CF CSEs, and not even the 3 with the most sites (I know mine's new, and perhaps Jeff's is, but Joshua's has been around since October, so this failure to find them using the search feature is dismaying, and I told Google that).

Based on a few comments below, I have added a couple more (Adam's and the HouseofFusion CSE), as well as updated Jeff's site count. I don't want to keep this up to date. As I say above, you can see the site count via the "real cse home page" link for each CSE.

Got a modern Dell laptop? You may have a built in hot-spot finder you didn't know about

You know how sometimes you're traveling with your laptop and wonder if you might have a wireless network available? Wouldn't it be nice to detect that without having to turn on your laptop? Well, there are certainly devices you can buy (hotspot finders) which can help you identify when your near a hotspot, but I just learned of a feature built into my Dell Latitude D620 (and which is in others like the D420 and 820, and some XPZ units).

Called the "wi-fi catcher", it's that switch on the left side (on my unit), which I knew could be used to turn the wireless adapter off or on. But if you pull it toward you, that enables this "wi-fi catcher".

Cooler still, and to the point above, it turns out that this feature works even when the laptop is turned off (or in standby or hibernate). One thing, though: you need to enabled this feature using the Dell QuickSet mechanism (one of your icons in the system tray).

You can learn more about the wi-fi catcher, in this case about the d620, at:


Here's a screenshot of the switch:

And an explanation of that screenshot is here, including an explanation of the colors you'll see and what they mean.

Finally, I'll point that I first read of this feature myself at this review:


Sure, we should all read our owner's manuals, but at a minimum, sometimes you learn more from someone's distilled review. :-)

Most of us CF/web app developers aren't particularly skilled at site design/layout/CSS, etc. If you're creating a new site for yourself or clients, how would you like to know about a repository of over 1,600 free, well-designed, CSS-based, XHTML-compliant web site designs? Check out http://www.oswd.org/, a 5-year old repository of just that. Indeed, if you like the design of my site (carehart.org), I got it there, as mentioned at the bottom of my site's front page. Just thought others might not yet have heard about the resource. Enjoy!

Do you blog? Do you identify yourself on your blog? Please do!

Note: This blog post is from 2006. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
I'm so surprised by how many blogs I come across where the blogger has not identified themselves in any way: no name, no bio, no email link. I suppose some may do it intentionally, as some form of anonymity (and I do realize why some may not want to list their email), but I honestly think most just had't thought about whether to list their name or anything more.

I'd like to put out a plea to at least consider listing your name, either in your title ("clever name - by blogger name"), or just in some text below it, or in your toolbar. Better still would be a small bio, or a link to a page that has one. (Maybe it would help if blog software offered an "about" pod that made you think of it more readily.) A photo would be nice, too. And for reasons (and with cautions) I propose below, I recommend you also list your email address.

Why bother with name, bio, and/or email? Because it's in your interest!

There are a couple of reasons to consider it, and they help both you and your readers.

First, as for listing at least your name, a good reason is simply to associate yourself with all the value you create by your blog. Why not get credit for your work? Plus, many would really like to know who you are. (And if your blog software puts a tiny "by" under each blog entry, I'll argue that's not enough. I've missed that myself on more than one site.) Again, whether in the title, below it, or in the toolbar, just put it somewhere! :-)

As for a bio, again, even just a couple sentences about yourself (below the title or in the toolbar) can really personalize the blog. Don't assume everyone knows your background, even if they know you by name. Many readers will appreciate knowing more about where you work, where you're from, etc. Such details can also lend perspective to what you write about. (For instance, if you're a fan or a foe of something where that would color all of your posts, it can be helpful for people to realize, "oh, he works for them|on that open source project|with that tool| etc.)." Let people know where you're coming from.) But at least consider offering some background, even a single sentence.

Finally, as for your email address, someone may want to contact you to offer feedback that's not specific to a post. They may want to offer you work (and not want to announce that in a blog comment)--and even then, which post should they enter such a generic note to you in, anyway? Keep in mind that not all readers realize that you get notified of all comments by email, so they may give up trying to contact you.

Heck, they may even have trouble posting a comment, and therefore need *some* way to contact you. I've certainly seen that before.

But isn't it bad to post your email address online?

OK, I realize you may not want to offer your email, as spambots will capture it. But you've probably noticed more and more people listing their addresses as "name (at) domain". The thinking is that people can figure that out, but spambots (at least the dummer ones) will not. I'll grant that they'll eventually catch on. You just need to way how important the benefits are against the pain of more spam. (You do have a spam catching program, I hope? I love the one I use, Cloudmark Desktop. No, it's not free, but there are certainly many of them you can check out.)

Be careful using that (at) trick with Mailto links
If you do decide to use the (at) approach, but you also offer a mailto link, like:

be careful: you need to list the "anti-spammer" address in the mailto (used to launch the email) as well as between the a tags (as shown to the user). Spambots grab all the text on your page, not just what's "visible". This is a pain, because then in the email that's opened the user must notice that you've done this and change it, or the mail will fail to get to you. What I do is explain to the user that by forcing some body text into the mail that's opened. Did you know that was possible?

<a href="mailto:charlie (at) carehart.org?body=please change the spam-fighting email address format I filled in for you, replacing the (at)!">charlie (at) carehart.org</a>

And for those who maybe already knew about it, did you know that you could also use:

<a href="http://tipicalcharlie.blog-city.com/forcing_a_line_break_in_an_html_email_link.htm">force a line break within such content in an HTML email link</a>
(this is from another blog of mine, typicalcharlie.com, which is for generic, non-CF tips)

So please, bloggers, step up and identify yourself. We'll all appreciate it!
