Pulling Adobe Docker CF images, for now via Amazon ECR or Bintray, and soon via Dockerhub

Here's some good news for those interested in using the Adobe CF Docker images: it turns out you are NOT required to do the clunky "download/docker load" dance that had been announced in this Adobe blog post on Apr 30, the day before the closure of the previous registry they used, Bintray. There are three other alternatives to do a traditional docker pull, which I didn't know about and I suspect others may not either:
  • First, you can now pull images from Amazon Elastic Container Registry (ECR), including both the CF2021 image and 2018, as well as the add-on and PMT images for CF2021. These are official Adobe images, to be clear. A simple example--that works today--and will give you the CF2021 update 1 image is the following:
    docker pull public.ecr.aws/adobe/coldfusion:latest
  • Second, soon you will be able to download them from DockerHub as well ("the way it's supposed to be", some would say). No date set for that, but indications are that it will be "very soon", according to Adobe
  • Finally, despite what the Adobe and Bintray sites said about the May 1 "closure" of bintray, saying that images would be inaccessible after that date, Docker images at Bintray DO remain available for now. This includes CF2021 update 1, CF2018 update 11, CF2016 update 17, and more, so existing docker pulls against those do still work, at least as I write today, June 17 2021

Both the first two were mentioned in a comment yesterday on the Adobe CF forums. And I discovered how the continued Bintray image availability while writing up this post to share the news about those other two!

For more information, including additional background on this transition, more on using the ECR images, and still more links to resources discussing these things, including docs on using the Adobe CF images that many never seem to notice, read on.

My upcoming talk, "ColdFusion at 25: not the kid most have stuck in their minds"

As you may have heard by now, the free Adobe CF Developer Week 2021 will be held June 22-24. My session will be on June 22 at 4p Central in Track 2. While currently the DevWeek site only offers session titles and speakers (descriptions were added after I posted this: click the + sign to the right of each talk), here is mine, from the "presentations" page here on my site:

ColdFusion at 25: not the kid most have stuck in their minds

As ColdFusion turns 26 next month, many seem stuck remembering it only as the "teen" they knew or even the "child", when instead it's grown up to be a capable "adult", impressive in many ways, and even more so recently. In this session, we'll look back at how CF has indeed evolved into a very capable platform, with quite modern features that seem to surprise many--including people working with it currently. If you struggle "finding CF people" or "getting buy-in", perhaps these observations could help you with both challenges. If nothing else, they're things designed simply to help you get your job done, while keeping up with modern practices.

We'll start with many modern coding techniques--which will be familiar to those using more "modern" languages but that many don't realize CF supports, and may have for years. We'll then look at ways that things such as CF installation/deployment, configuration/administration, monitoring, security, and more have improved over the years. And we'll look not only at CF itself but the community surrounding it, ranging from resources for help and learning to tools and services that others have created, making CF a far more complete ecosystem than most give it credit. Put another way: it's not your father's CF!

I look forward to presenting this topic and hope you'll come check it out.

I'll be speaking on the Online CFMeetup this week, on installing CF2021

I thought some readers may want to hear that I'll be speaking on the Online CFMeetup this week, specifically "Installing CF2021: choices, challenges, and solutions".

That may sound like a boring or simplistic topic to some. "Doesn't everyone already know how to install CF?" Trust me, they do not. :-) I help people do it every week, whether CF2021 or earlier versions. There are various tips I can and will share, and of course some about CF2021 in particular. But much will benefit you even if still using an older CF version.

For more on the talk, including a description (and my bio) see the meetup event page, which offers details like the URL for attending, the date and time (Thursday at 12p Eastern), and more.

I have just realized that I've been derelict in announcing here on my blog when I'm giving such talks. I did 3 meetup sessions last year, as well as a couple of AMA ("ask me anything") sessions with Dan Wilson, who has been helping me in running the group the past year, with my sincere thanks! :-)

New updates released for Java 8 and 11, April 20 2021

For those using the Long-term support (LTS) versions of Oracle Java, 8 and 11, please note that there were new updates released last week (Apr 20), specifically Java 11.0.11 and 8.0_291. For more on each, see the:

For some, that's all they need to hear. For others, read on.

Confirming ColdFusion's Java version via CFML code

Have you ever wished you could confirm with 100% certainty what Java version is in use by the CF instance you are running? Or where the JVM's location is (in case you are told to modify files related to it)?

Some good news is that ColdFusion offers simple ways/variables that can show you each of these, via CFML code. In this post, I share that. I share first a simple single variable which works in CF2018 and above, then I offer a variation for those on CF2016 and earlier, as well as variations for Lucee.

As Rakshith moves on, ColdFusion Product Management past and future

Some of you may heard that late last week Adobe CF Product Manager Rakshith Naresh announced in various online communities that he was stepping down from the role and indeed moving on from Adobe. Here's his post on the Facebook CF Programmers group. As he noted there, he had "found an interesting opportunity outside of Adobe", and he added that "ColdFusion continues to be an important part [of] Adobe and nothing changes for the product with this. Adobe is actively looking to hire a replacement for my role."

Of course I wish Rakshith all the best. He guided the release of CF2021, which many think is one of the best new CF releases in that timeframe, and he will be missed. But time marches on, as does CF.

In this post, I reminisce first about who the past (surprisingly few) CF Product Managers were, and then I muse about what the next CF PM will face, and what all this means for CF going forward.

Version numbers of libraries underlying ColdFusion 2021

Are you wondering what updates have been made (in terms of version numbers) to the libraries underlying CF2021?

For instance, what's the version of ehcache? What about Java, Tomcat, Hibernate, Quartz, jQuery, and so on?

In this post, I offer a rundown of what seem the most significant libraries and their versions, as deployed in the first release of ColdFusion (2021 Release). This is something I have been doing in my "hidden gems" talks for the past several releases. I also explain here how I find these version numbers, which isn't always obvious, in case that may help anyone (and also because some libraries may change with future updates to CF2021). I also offer some commentary on why this matter of library versions is important to some, as well as some counterpoints to the demands some have that every library should always be the absolute latest version (and why that's just not practicable).

If you just want the version numbers without the "waffle", look for the bulleted list of them below. :-)

How to disable the Asus NumberPad, embedded within touchpad on some modern laptops

Do you have a modern Asus laptop with the NumberPad (orNumPad) feature (a virtual numeric keypad embedded within the touchpad)? You may know there's a button to enable/disable it on demand, but do you find find it coming on when you brush that by mistake? Are you annoyed that you can't find how to "permanently" disable it?

In this post, I discuss ways to try to do it. There are various ones. Removing the numberpad driver (NOT the touchpad's driver) from Windows Device Manager seemed at first the best way, but it proved to be temporary. Others later proposed various ways to try to remove it permanently, but those don't seem to work, either.

TLDR; See below for how to do that if you may prefer to cut to the chase, but interested readers may want to understand a few things first, like what I mean by the Numberpad feature, and the problem that may prompt folks to seek how to disable it, as well as other solutions that I found had been proposed (even before I wrote this post) but also did not work. Then I conclude with what has, for me (so far).

Hotfix released for CF2021 date-mask compatibility issue

[Update: Adobe offered this "fix" also in the March 2021 release of CF2021 Update 1. As such, you need not obtain the fix jar file as discussed below. but the rest of the information applies--including the fact that even after the update, the DEFAULT is still for the D dateformat to be a "breaking change", which you can "undo" with the JVM arg discussed.]

Good news to share: if you're concerned about being impacted by a pressing compatibility issue in ColdFusion 2021 (regarding using "D" in a dateformat mask), Adobe released a fix for the problem last week. There are 3 simple steps to implementing that hotfix.

For more on the problem, see see my recent post on the issue. For more on the fix, see that Adobe technote or read on for some additional details.

Breaking change in CF2021, new date format mask of D may be serious problem for old code

Wow. Beware of this subtle breaking change in CF2021, something discovered since its release (was not documented as one of the "new" things, nor was it documented at all in the beta).

[Update 1, Dec 2020: the week after I posted this, Adobe posted an optional fix for this. See my Dec 2020 post as well as the comment below from Sauarav, where they have offered both a hotfix jar and a jvm argument that you can use, if you want to revert CF2021 to treating the "D" datemask format as it had in prior releases. Read on for an explanation of the problem, to appreciate the available solution. In time I'll do a separate post with more on the update.]

[Update 2, Mar 2021: Adobe offered this "fix" also in the March 2021 release of CF2021 Update 1. As such, you need not obtain the fix jar file as discussed below. but the rest of the information applies--including the fact that even after the update, the DEFAULT is still for the D dateformat to be a "breaking change", which you can "undo" with the JVM arg discussed.]
