Recordings from ColdFusion Developer Week 2017

If you didn't hear, you can get free access to view the recordings of the Adobe ColdFusion Developer Week (devweek) which was held July 31-Aug 4 and offered several useful sessions.

And unlike previous Adobe cfdevweeks, which often involved non-Adobe presenters (including myself), this year's sessions were all from members of the Adobe CF team, on these topics:

  • The now and the next of Adobe ColdFusion (you'll have to suffer through a mistaken use of background music the whole hour)
  • API Economy: Realizing The Business Value of APIs Through Adobe API Management (no music in this or subsequent recordings)
  • Design of Rest API and Rest in ColdFusion
  • Upgrade to CF 2016
  • Finding security vulnerabilities in your codebase using security analyzer
  • Load Balancing, Scalability and Failover with ColdFusion Clustering
  • PDF enhancements in ColdFusion 2016
  • Language enhancements in CF 2016
  • Scale with ColdFusion 2016

About the very unfortunate background music in the first session, I have reached out to Rakshith today to ask if he may want to repeat it on the Online ColdFusion Meetup that I host, and we could offer that recording then as an alternative to the original.

Of course, the availability of the recordings is not new new info, as they were released last month and mentioned in that post I link to above. But I noticed in doing a google search today for "coldfusion devweek 2017 recordings", the first result was my 2012 post on the recordings of that year's devweek. Doh! So I wanted to offer this update in the hopes of replacing that in searches (fortunately, the Adobe post does appear next for me). I also just added "2012" to the title of that older post, as well as a link to this one, to perhaps also help avoid confusion.

And if you're interested in seeing the 2017 Adobe CF Roadmap (about what's new recently, what's coming in 2018 and 2020, as well as support timelines), Adobe happened to blog about that today as well. The sessions above (especially the first) elaborate much more on these than the 3-page PDF with a few bullet points each on CF2018 and CF2020. You'll see I pointed this out in the comments there, and I offered a link to the recordings. And it was in trying to find that which led to the motivation to create this post above. :-)

Dealing with Adobe forums error, "a serious error has occurred in the system"

I happened to try to visit today an Adobe forums page, when I got this error:

System Error

We're sorry but a serious error has occurred in the system.

If this happens to you, I have a possible quick solution (if you just want to get to the page in question):

Use your browser's menu option to have it create a "new private window" (FireFox), or "new incognito Window" (Chrome), or "new session" (IE), or the like.

This will open a new window for your browser, and it will NOT send any cookies to the page in question. And you should find that suddenly the forums "work", which tells you that the problem was about the server's unhappiness with something about the cookies in your browser.

If that's enough, great. If you want to know a bit more, read on.

Having issues with the popup calendar feature after CF11 update 12 or CF2016 update 4? There's a fix

If you're using the cfinput type="datefield" feature to popup an calendar and are finding that it's not working correctly after ColdFusion 11 update 12 or ColdFusion 2016 update 4, there's a fix for it. (This could also happen if you're moving to CF11 or 2016 for the first time and someone else fully updated it before you started testing against it.)

The issue is discussed in a CF bug entry, CF-4198570, but since I've had a couple of customers recently ask for help on it, I thought I'd bring it up in a blog post here.

TLDR: you just need to obtain a special hotfix jar file, either the one for CF11 or the one for CF2016. (If you find that just clicking the link shows you gibberish in your browser, right-click the link and save the file instead.)

Put that saved jar in the lib\updates folder for your instance(s), and restart CF, and the problem will go away.

For more on the matter, as always, see below. :-)

VisualVM failing to find plugins/updates? Solving the 503 error with an updated URL

Have you tried to update or simply see the available plugins for VisualVM (the Java monitoring tool built into the JDK), and found that it fails to respond right away (the progress bar will show "checking") and then it reports:

Unable to connect to the Java VisualVM Plugins Center because of Server returned HTTP response code: 503 for URL: http://www.oracle.com/splash/java.net/maintenance/index.html

There is a solution.

TLDR: the quick answer is to change the URL used by the tool (Tools>Plugins>Settings) to use a new URL, such as https://visualvm.github.io/uc/8u131/updates.xml.gz.


For those who'd appreciate more detail, read on.

Long-time CFer needing to find new non-CF work? You may know more than you realize

Hey CFers: if you're thinking of getting (or are being forced) out of CF, and feel you can't find work, do you feel stuck? You probably know a lot more in terms of marketable skills than you may think.

This is a follow-up to my last post, Looking for CF people, or CF work? What can you do?.

In that one, I focused mostly on helping someone who WANTS to stay in CF, or as important, those who HAVE WORK TO OFFER in CF but have a hard time finding people.

Now this is for someone on the other side of the fence, who is now out of work in CF (by choice or circumstance) and needing to find work OUTSIDE of CF, and can't wait to develop new skills.

Looking for CF people, or CF work? What can you do?

I'm often asked by clients or folks in the community about whether I know anyone who could do some CF development work (or how they can find someone), or whether I know of any jobs/gigs available (or how they can find them).

I do have a pretty standard answer, and it's not what I think most would expect to hear in reply (if they thought I could just propose some possible specific people looking/available).

Recordings for nearly a dozen recent FusionReactor webinars I've done

I've been doing a series of one-hour webinars about FusionReactor over the past several months. They've covered nearly a dozen different topics (all with live demos), with more to come, including one just last week, "Making the Most of FusionReactor's Logs".

You can learn more about that and the previous ones and find their recordings at fusion-reactor.com/webinars. I also list all the webinars below, with links to each webinar's page with its recording.

(Note that sometimes the description offered on the main webinars page is a truncated variant, but click on the session link there or my links below which take you to the recording and the full description.)

Of course you'll find future webinars on the FR webinars page as their dates are posted, and you can register for them then (all free). By attending live of course you can ask questions as we go.

Some of the webinars are geared more toward folks who've been using FR (though maybe not to its maximum potential) though I try to make even them accessible to newcomers, while others are more well-suited to newcomers. (To be clear, I don't work for the company that makes the product, but I've been a huge fan for over 10 years.)

Easily finding cached versions of a site/page when it's down or gone

Have you ever had a web site "go dark" on you? or found that a given page on a site somehow disappeared? Maybe it's only temporary (there may even be a "we're down" message, though the site or server may just fail to respond at all), or maybe the failure of the page or site will be permanent.

The good news is that there are at least two easy ways that you may well still be able to see that content you may be missing: the Google cache (to at least see the last version which Google may have cached), and the internet archive "wayback machine", which often lets you see YEARS back in the history of a page or entire site, including one that may be long-gone.

In this post I share tips (and gotchas) on using both tools.

They aren't GUARANTEED to have the page you're looking for, but I find that they do about 99% of the time I try them (and I use them a lot, because I'm often mining gold in old blog posts or articles which have gone away across many sites I have visited).

[Updated June 9 in a variety of ways, mostly minor, but with some additions in the "trip down memory lane" discussion.)
