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

Note: This blog post is from 2017. Some content may be outdated--though not necessarily.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.
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

Note: This blog post is from 2017. Some content may be outdated--though not necessarily.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.
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?

Note: This blog post is from 2017. Some content may be outdated--though not necessarily.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 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 most would expect to hear.

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".

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

Note: This blog post is from 2017. 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.
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)
  • 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.
  • and still another couple of options

TLDR;

Try putting either cache: or web.archive.org/ in front of the URL of whatever page you're trying to visit, as in:

http://web.archive.org/https://www.carehart.org/index.cfm

to perhaps see years of archived versions of a page/site.

Or to see any Google snapshot of the most recent cached version of a page, use this in a Google search,

cache:https://www.carehart.org/index.cfm

Either may or may not work, for various reasons I explain below. And note that this works for domain names or individual web page URLs. You may find that it also works with or without the protocol (http:// or https://), but try using it the other way if one does not work.

For much more, read on, as I share tips (and gotchas) on using both tools.

My upcoming presentations for spring/summer 2017: some on CF, some on other topics

Note: This blog post is from 2017. 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 going to be speaking several times in the coming weeks and months (on several topics, some on ColdFusion and/or CFML, some on generic topics applying to any server, and one on SQL Server 2016 SP1 specifically). I thought I ought to post that fact here (I have often failed to think to do that here over the years).

I offer below first the events at which I'll be speaking, and then the preso titles and descriptions for any readers interested. (As an update, I was informed on 5/16/17 that I'd been selected to speak at NCDevCon. While it's not in "spring/summer" per the subject above, I've added it to the info below.)

Dates announced for all six remaining ColdFusion/CFML conferences, and more Adobe CF Roadshow events

Note: This blog post is from 2017. 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.
Did you know there will again be 6 CF/CFML-related conferences this year? (An update: I should have said "six remaining", as there was also Muracon which happened last month. I've modified the title to be more clear.)

I had posted last month about the upcoming CF/CFML-related conferences and some other events which had BY THEN announced their dates (3 of them). I mentioned the other 3 that would typically happen, and indeed since then, those 3 have also announced their dates. And Adobe has announced still more CF Roadshow events.

So here's all the current detail on all 6 remaining CF/CFML conferences (their name, description, date, location, link, and info on call for speakers).

I thought I'd take a moment to share news of several upcoming CF/CFML-related events, from conferences to half-day events, some as early as next week. First up are the upcoming conferences:

The 100 most interesting posts on the Adobe ColdFusion blog, the past 3 years

Note: This blog post is from 2017. 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.
The Adobe ColdFusion team blog often has really some interesting content, but I find that some people are either not aware of the blog or just don't keep up on it, or perhaps they have trouble finding something they saw before or maybe heard was there.

So here I present what I feel are the 100 (technically, 105) most interesting/useful posts made there over the past 3 years (2014-16), offering information about CF and CFML which should be valuable to readers for years to come.

I thought it may be useful to gather up a categorized listing of my most (seemingly) helpful/resourceful blog posts of the past year, to help others be aware of them (and indeed to help me be reminded).
