[Looking for Charlie's main web site?]

I'll be speaking at CFCamp in Munich, Germany, Oct 20-21. See you there!

I'm delighted to announce that I'll be presenting again this year at CFCamp, in Munich, Oct 20-21.

I'll be speaking at the Adobe ColdFusion Summit in Vegas, Oct 10-11. See you there!

Many have been asking if I'd be speaking again at this year's Adobe ColdFusion Summit, in Last Vegas (Oct 10-11). I will indeed!

(There was some challenge in getting all the speakers posted until just last week, so though I had known I was speaking for months, I held off announcing it until I could point to the link.)

I'll be presenting (as I do for each release) my "Hidden Gems In ColdFusion 2016" See the description via the links above. It should be as classically useful as ever, whether for those either new to or experienced with CF 2016.

I certainly do appreciate the conference team selecting me again to be a speaker. I've spoken at each of the 3 so far, the first in 2013.

The conference is always a great time (and has gotten larger and better each year, by most accounts). And Vegas is of course a great location (though honestly I barely leave the venue the whole time). Then there are all the great attendees, and sponsor booths, as well as nearly the entire CF team on hand, and of course lots of useful information shared from all the presenters.

If you'll be attending, I hope to see you there! And if you're still considering it, see the Why attend? page and other links offered there. Finally, note that the "early bird" price has been extended to August 31. See the Pricing page.

I'll be speaking at dev.Objective() conference, June 15-17. See you there!

I'll be speaking at next week's dev.Objective() Conference, in Minneapolis (June 15-17). The conference is always a great time, in a great location, with great people, and lots of useful information shared, and I appreciate the conference team selecting me again to be a speaker. If you'll be attending, I hope to see you!

I'll be presenting two talks, "Hidden Gems In ColdFusion 2016" (as my personal talk) and the sponsor talk for the Integral (FusionReactor) folks, "Keep Applications Online And Detect & Isolate Application Issues & Performance Bottlenecks In No Time With FusionReactor 6".

See the descriptions for each, via the links above. My Hidden Gems talk should be as classically useful as ever, for those either new to or experienced with CF 2016. And the FR 6 talk will be more than "just another intro" to FR, highlighting as it will the important new features of FR6. Again, see the description [I wrote the description, they picked the title :-)] to appreciate what it will be about.

Also, let me give a heads-up to all attending: do be sure to look at the email that was sent out today or yesterday, with all kinds of important information to be aware of, from timing of events, to ground transport, to the very important map to see how to get from the conference hotel to the conference location at the college just a few minutes away, and more.

See you at dev.Objective() in mid-May (I'll be speaking)

Just wanted to share word (sorry it took so long) that I'd been selected as a speaker at the upcoming dev.Objective() conference, in Minneapolis in Mid-May. Hope to see lots of my fellow CFers there, and of course new folks who were not CFers.

While the conference name has changed (from cf.Objective()), there are still plenty of CF-oriented topics, and of course as nearly everyone would point out, it's good for everyone to expand their reach and focus.

To that end, I'll be doing a topic a bit different than my normal focus of CF server troubleshooting. Instead, recognizing that there will be folks there who either use other servers, or develop web apps or mobile apps, I'll do a bit of a "soft" topic on how to troubleshoot performance problems more generically, in:

Hey, my web app's slow. Where's the problem?

My presentations at ColdFusion Summit, CFCamp, etc.

I wanted to share word here of the presentations I'll be offering at the upcoming Adobe ColdFusion Summit 2014 in Vegas on Oct 16-17, as well as CFCamp 2014 in Munich on Oct 20-21.

Also, sorry for the long delay in blogging. Just been so busy doing my CF server troubleshooting consulting.

As for my sessions at CFSummit (next week), I'll be doing the following (and you can follow the links to learn more about the talks, their dates and times, etc.):

At CFCamp, the following week, I'll be offering:

I had also presented the Hidden Gems talk at NCDevCon 2014.

These are all great conferences, and, in addition to cf.Objective 2014 (where I spoke also, on different topics), they are each great ways to keep up on what's going on in the world of ColdFusion and related technologies.

Finally, if someday you're visiting this blog entry and find that one of the conference links no longer work, you can find my own link to all my presentations, at all conferences the past 15+ years (as well as to any recordings made available) at my presentations page.

Come say hello if you're at any of these events.

Two videos I've done for the Adobe YouTube ColdFusion Channel

Hey folks, I've done a couple of videos over the past several months on the Adobe YouTube ColdFusion channel, both focused on some important challenges related to ColdFusion 10. If you've got about 10 minutes to spare, I suspect you may learn things to surprise you.

First video, on single-login problems in CF10 Admin

The first video was done at cf.Objective() in May 2013, and was posted to YouTube by Adobe shortly thereafter:

Video 1: Solving the problem of single-login in ColdFusion10 (07m:32s)

If you've had the problem in CF10 of finding that you login to the Admin, only to be logged off soon thereafter, I explain in the video both why it happens and how to solve it. (I also wrote about it previously here.)

Second video, on important security hotfix notes document

The second video was done back in June, but sadly was not posted until last week. While the timeframe references I make are dated, the information shared is not and really may still be a surprise to as many now as back then:

Video 2: Security Hotfix Notes Document (5m46s)

This is such an important document. I also had written about it previously here.

See other CF videos there

Be sure to check out all the videos in the Adobe CF YouTube channel, about 20 of them currently, from different speakers and on many topics.

Don't forget to vote, for cf.Objective() 2014 topics, including 2 ColdFusion talks from me

By now you may have heard that the call for speakers for the cf.Objective() 2014 conference closed a couple of weeks ago and now it's time to vote among the posted topics using the conference Trello board.

I wanted to point out to my readers that I have proposed two talks. The first one I gave at the Adobe CF summit last month and was very well-received. You can see the description and VOTE button on each of the following pages:

CF911: Solving Frequent CF Server Problems in New/Better Ways (click to visit, then vote)

The second is one that I gave to the Atlanta CFUG earlier this year.

Updating/Hotfixing ColdFusion 10, 9 and 8: Tips and Traps (click to visit, then vote)

Both are full of surprising and helpful tips, based on my experience helping hundreds of shops with related issues in my CF server troubleshooting services. But the talks are not "sales pitches".

They're goal is to be just like my blog entries here, and my past talks: I just want to help people find, understand, and resolve problems with their CF servers. It's wonderful to be able to help people come away more confident and capable in managing their servers, whether from the consulting sessions, the talks, the blog entries, the cf911.com wiki of cf server troubleshooting resources, the cf411.com site of tools and resources of interest to CFers, and so on.

Anyway, if these talks sound interesting, please go add your votes using the link for each above, and click the vote option that then appears. And of course, vote for all the other talks you think ought to be invited. The board uses your votes, so every vote counts.

Speaking at Atlanta ColdFusion User Group tonight on 2 important topics

Just wanted to note that I'll be speaking tonight at the Atlanta CFUG on two important topics:

For more details on the talks, or to get the slides once I post them (likely right after the meeting), please see the links for the two sessions above.

And if you may want to attend, please RSVP.

I may offer these later on the Online ColdFusion Meetup or perhaps one of the remaining CF conferences this year, if I may be selected to speak.

Recordings from ColdFusion Dev Week (cfdevweek) Now Posted

If you missed any of the sessions from last week's ColdFusion Dev Week, or want to watch them again, you can now see the recordings for all of them. Just click the link for your desired session on this page.

Note that you do still need to use an Adobe account login to view them.

For my two talks, the direct links (still requiring your Adobe account login) are:

I'll be presenting two talks online at ColdFusion Developer Week (CFDevWeek), June 4-8th

Join me and over a dozen other presenters as we present (for free, online) 19 sessions over 5 days for the upcoming Adobe ColdFusion Developer Week 2012. Some of the sessions are on CF10, but others are not.

As for my talks, I'll be presenting my two cf.Objective() talks. Here are links for the description and my bio for each, but note that SIGNUP is done on the main page above:

These talks went very well both at cf.objective() and at the week-long CF10/Scotch on the Road tour where I presented them last week in 5 cities in Europe, so the talks are also well-practiced!

That said, I may tweak their look/feel or add new content before next week (indeed, I have tweaked the content considerably since the conference and did so also as the week progressed last week, adding new discoveries at each new city as I had so much time to explore during the trip.)

Please note the following points which I'm sure some would want to ask:

  • The times offered (above and on the site) are US PACIFIC time. Adjust your calendar entries accordingly!
  • You DO have to register (for free) at that first URL, to get the info for joining in on each Connect meeting
  • Yes, the meetings will be recorded (although many enjoy participating in the live talks so that they can get questions answered during or after the session). I'll offer a link here (and/or as a new entry) when the recordings are posted.

Finally, If you want to an easy URL to offer for that is http://adobe.com/go/cfdeveloperweek, and note that the hashtag for it is #CFDevWeek.

Speaking May 21-25 in 5-day European ColdFusion Road Tour, Scotch on the Road

Cool news! I'll see some old friends and make new ones next week in Europe, where I will be repeating my two talks from cf.objective() as part of a 5-day European Road Tour, the 2012 Scotch on the Road event.

Along with a few other speakers, we'll present sessions in Munich (May 21), Zurich (May 22), Paris (May 23), Brussels (May 24), and Amsterdam (May 25). See the tour dates page for details on the locations and agenda for each city.

Pretty sweet! :-) I always love going to Europe, and this will be my first time in Paris and Brussels. I'm certainly grateful to have been invited. I'll leave cf.objective on Saturday afternoon to fly right to Munich. Sadly, my wife couldn't join me (for reasons that I'll explain in a moment.)

Some may know the Scotch on the Rocks event has traditionally taken place in Edinburgh (where I had the pleasure to speak previously). And the "Scotch on the road" moniker has been used before when it's happened in another city or cities.

Hitting the road in a tour bus!

Speaking this week at cf.Objective(): Two coldfusion sessions and a lightning round talk

Just a heads up for those at cf.objective, which starts tomorrow. I'll be presenting 3 times.

First, I'm giving two different sessions on Thursday and Friday:

See the links above for details on each talk. And as always, I'll post these talks (after presenting them) on my presentations page.

Then, on Thursday evening I'm giving a Lightning Round talk. Last year I did one on "Lies, Damned Lies, and Request Timeouts". This year, I will again do a CF-centric talk--someone has to talk about something other than beer, love, and other heartwarming or life-expanding talks. :-) This year, it will be "10 Things That Plague Most CF Servers, with Solutions". Yep, even in 6 minutes, I hope to share some surprises that many miss, but which I see daily in helping people in my CF server troubleshooting consulting services.

I'll be posting the presentation for that as well, but it will have additional detail (in terms of resources to learn more) on each topic.

Looking forward to seeing old friends and making new ones. Please come say hello, and be gentle with me if I may not make an immediate connection of face to name. :-) With the blessing of attending and speaking at so many conferences comes the curse of meeting lots of people, only briefly, and often only once (or once in a great while!)

Finally, I'll note I am also presenting the first two talks above again next week, in a 5-city European tour. More on that here: Speaking May 21-25 in 5-day European #ColdFusion Road Tour, Scotch on the Road.

Recording of my Adobe eseminar session, "Monitoring ColdFusion with FusionReactor"

After my barrage Friday of four entries on the CF Server Monitor, here's something instead on FusionReactor. Some may know that last week I did a talk on the Adobe ColdFusion eseminar series, "Monitoring ColdFusion with FusionReactor". I got word today that the recording link has been posted.

You can find the recording here. Note that you need to login with an Adobe ID, just like when you download Adobe software or participate in their forums. (I have no control over that.)

Since that link just goes right to the recording, here is the description I'd used for the session, to help decide if the recording may interest you. BTW, I clarify on the session that FR is useful for more than just ColdFusion, in that FusionReactor can be used for Railo, BlueDragon, and OpenBlueDragon, as well as in fact any Java server (Tomcat, JBoss, Jetty, Glassfish, Websphere, etc.), and the session applies just as well to folks using those.

My session: Monitoring ColdFusion with FusionReactor

My catalog of 50 ColdFusion Zeus features discussed publicly so far

Would you be interested in a catalog of what features have been identified (new, changed, or removed) in ColdFusion Zeus? Would you be surprised to hear that there are about 50 that have been mentioned so far?

Check out what the presentation I offered today, "What's Next In CF Zeus?" (PDF of slides), which I presented at CFCamp in Munich.

(I had mentioned last week that I would be presenting this and another presentation, as well as a daylong class. BTW, the daylong class was popular, with 13 students. Great to meet all those who attended.)

I explain in the slides how I gathered the info, from 5 public Adobe Zeus sessions I've seen so far. None of those had yet cataloged ALL features that had been shown in the other sessions. There were certain things mentioned in all 4, but then also each showed things (or in more detail) that the other did not. I enjoyed pulling this all together in this talk.

As I also note in the slides, I was not permitted to show live demos (only Adobe employees can do that), but still the listing of features and brief discussions (including some code) should still be valuable. I also point to the URLs for the 4 currently available recorded public Adobe sessions, which do in fact offer more code and live demos.

I suspect I'll offer the talk soon on the CFMeetup. I may also present them in another form. But until then, enjoy the slides.

Do let me know if it's a useful list for you, or if I left anything out!

I'm speaking this evening on the Adobe CF Developer Week webinars: mine on CF Server Monitor

Hey folks, just a heads up (for those who may not have seen all the tweets and list messages) that this week is the Adobe CF Developer Week series of free webinars.

Update, Recording: Note that this session was recorded. You can view it here, but note that you must login with an Adobe ID to see it.

And I'm presenting a session tonight, Tuesday September 13, at 7pm Eastern, on "Understanding and Using the ColdFusion Server Monitor".

As many of you know, I'm pretty much a fanatic about the monitor, especially about truly understanding elements of it that many miss. And so in my talk this will not be just a dog and pony show, but I will talk about practical experiences with it, though presented to either those new to it or experienced with it.

Note that the times for all these devweek sessions is shown (on the Adobe site) as being Pacific time, so again mine is at 7pm, not 4pm, Eastern.

And yes, the sessions are being recorded and seem to be made available the next day.

Finally, beware that there is no one URL you can use to join in on all the Connect sessions, nor can you get the Connect session URL by going to the event page (via the first link above). Instead, you must register for each event (free) from that first page, to get each session's Connect URL--and you'll want to do that at least several minutes in advance of any session to have time to register, get the email, login, etc.

See you then.

PS Hey, while we're talking monitoring, note as well that if you've not heard, FusionReactor has come out with its new release 4, which has lots of great additions, especially FREC (or the FR Extensions for CF) which cause FR to grab and log lots of great info that the CF Server Monitor only shows and never logs. I'll be blogging about FR 4 soon, but plenty to see on their site. and FusionAnalytics is also just about to release, really!

I won't be discussing these at this talk, focused solely on the server monitor, but as I always tell folks, each tool has its use and often a single shop can benefit from having both (like I do, as do many of the clients I help with troubleshooting). You can find more from me about FR here in my blog. And I'll have lots more to say about FA and FR4 more soon.

I'll be presenting at RIAcon next weekend: "CF911 ColdFusion Performance Report 2011"

I'm delighted to announce that I'll be presenting at next week's RIAcon conference in the DC area, August 6-7 2011.

My session will be "CF911 ColdFusion Performance Report 2011", a new talk/concept I've created. Here's the description:

Starting a new tradition, veteran CF troubleshooter Charlie Arehart will present a review of the performance aspects of making various choices when working with ColdFusion, especially in recent version(s) of ColdFusion. Leveraging the important value of real load testing (as opposed to the less accurate conclusions from "large loop" testing), Charlie's annual report will help attendees appreciate the performance-related improvements of new/changed features, as well some older features where choices can make an important impact. Depending on the timing of the release of "CF next", the session may cover its new features, but it will certainly cover some things new in CF 9 and 9.0.1.

As I note there, I hope this may become an annual event which I might present at this and/or other conferences. (It's an idea rooted in a similar presentation made by a former colleague, from my first IT career from 1982-1997, where he presented the annual "Jim Damon model 204 Performance Report".)

About RIACon

As for RIAcon, I hope you're considering it. Phil Nacelli and the folks at AboutWeb have been working hard to put together the conference, which in some minds is kind of picking up where CFUnited left off. It will be a more intimate event, much like CFunited was when it first started.

Indeed, some will recognize that the location for RIAcon is across the street from one of the hotels where CFunited was held in its early years, right next to the Twinbrook Metro station in Rockville, MD.

A Personal Connection to the Hotel Location

Even more of a delight for me personally is that the hotel (The Legacy Hotel) is right on the land that was once the location of Congressional Roller Skating Rink (until the late 70's), where my sister and I (and many friends) spent our teen years pretty much whenever we weren't in school. Yep, I was a skating nerd: dance, figures, freestyle, and more. Here's incriminating evidence!

cf.Objective(): I'll be there, and I'll be busy with 4 sessions

I've gotten word from the folks running the cf.Objective() conference that besides the 2 talks I'm giving, they've also recently accepted my proposals for a BOF (birds of a feather) session and a slot in their lightning talk session. Phew! I'll be busy.

Here are the details.

First are the two talks:

(I had put in just the first talk originally, and then a few weeks ago a slot opened and they asked if I could do the other, which I was happy to offer, as an reprisal/update to my talk from the first release.)

Then for the Lightning Round (or what was originally referred to as the Pecha Kucha), my talk will be:

  • Lies, damned lies, and CF request timeouts (in which I'll share in 5 minutes some information that even experienced developers admit having never known)

Finally, for the Birds of a Feather (no page on their site listing them yet), the session I will be leading will be:

  • CF911: Share your CF server troubleshooting tips (come share some ideas, or learn from myself and others)

Sense a theme? Yep, other than the CFBuilder talk, the other sessions are all focused on the topic that is now most near and dear to my heart (and livelihood): CF Server Troubleshooting. It's what I do, and more important it's how I feel I can best help the most people.

There's one last aspect of my involvement at the conference that I'll mention: they started a new sponsorship program this year called "Friends of cf.Objective()", and I'll be participating in that. No mention of it yet on their site, but there should be more news at the event.

So hope to see you there, or if you won't be there, I'll post if any of these are recorded, or if not then I would likely record them myself in the future.

I'm participating in Ray Camden's "Uber Panel of ColdFusion Awesomeness" tomorrow (Wednesday)

If you've not heard about it, Ray Camden is organizing what he's calling the "Uber Panel of ColdFusion Awesomeness". :-) And I'm delighted to have been asked to join the esteemed panel.

It will be held tomorrow (or today, depending on when/where you read this), Wednesday Dec 8 at 12pm US ET (GMT-5). It's an online session, held at:


And yes, it will be recorded (by Ray--keep an eye on his blog for more info, if you can't attend.)

To find out more, such as who else is on it, check out Ray's entry with more detail:


BTW, for those looking for the subsequent parts to my previously started series on solving memory-related errors, my apologies. I got sidetracked with travel. Will explain when I do part 2, which I hope to get posted very soon.

How do I love FusionReactor? Let me count the ways (6 minute interview video)

The folks behind FusionReactor have started a YouTube video channel and they recently posted a 6-minute interview with me that we did at CFUnited. In it, they ask and I recount the reasons I appreciate and recommend it. Check out the video, embedded also below.

FusionReactor is one of the leading CF Server Monitor tools, which works not only with CF 6/7/8/9, either Standard or Enterprise, but it also works with Railo, Open BlueDragon, and even BlueDragon JX 7.1. In fact, it works with any J2EE/JEE server or servlet engine.

If you're running a site on any of those platforms and ever have problems of slowness, instability, or any other "curious" problems, or just need to better understand the nature of requests that CF is processing, and how well (or poorly) it's doing it, FusionReactor is a great tool, for the reasons I outline. It's like having x-rays into the app server.

I've written and spoken about the tool quite a bit, and have a FusionReactor blog category here with over a dozen entries here, as well.

Some more recent (and upcoming) "appearances" (podcasts, interviews, speaking)

It always feels a little awkward pointing things like this out, but since some readers may want to know about them, I have recently been the subject of a few of what I'll call "appearances" (and I have a few more coming up):

  • I was a roundtable participant in last week's RiaPodcast episode 2.9 (you can listen there)
  • I was co-host on the CFHour() podcast, show #60 a couple of weeks ago (you can listen there)
  • I was invited (along with Michael Smith) to be interviewed by Judith Dinowitz of FusionAuthority on the recently announced fact that this would be the last year of CFUnited, which I've spoken at each year. (You can read the interview at the FA link offered.)
  • It was announced last week that I'll be hosting a BOF (birds of a feather) session at the CFUnited conference. The session will be "CF911: Server Troubleshooting". More details at the page above.
  • It was announced last week as well that I will be giving another session at CFUnited, this one being the Sponsor talk for Intergral (makers of FusionReactor, with whom I partner a lot). The topic is "Continuously Improve CF Code Quality, Server Availability & Application Stability". More details here.
  • Finally, more details about my Day 2 keynote at the conference were also announced a couple of weeks ago. The topic will be, "CFCommunity: You're Never Alone". More details at the link offered.
