Delighted to be speaking at CFCamp 2023

I'm delighted to announce that I've been selected to speak at CFCamp 2023, in Munich this June. This will be my 7th year in a row presenting at this wonderful event (not counting when it was skipped in 2020-22), and my 8th year total.

(While I said "thrilled" about my previous two conference announcements, saying "delighted" here is not a downgrade. Just a desire not to sound repetitive!)

My talk will be...

New look for CArehart.org, especially better for the blog on mobile

OK, so in my last post (celebrating my 600th post and 17th year blogging here) I happened to admit that the site still looked like it was from 2006--that's actually the year of the blogcfc 5.005 version that I based it on...and I never really changed the "look and feel" much.

Until this weekend...and it may not be noticeable to all, but I suspect some things will stand out to regular readers, starting with....

Blog much improved on mobile!

An interesting pair of anniversaries for my blog: 600 posts, over 17 years this month

After I posted my last entry, I happened to notice that it was exactly my 600th post here at carehart.org/blog. How about that? And in that time I've had 3,645 comments from folks. I do write mostly for you all, so thanks!

I also noticed that it marks my 17th year of blogging here, almost to the day with my first entry posted this same week back then, Apr 15 2006. That's "pretty darn interesting", as Ray Camden might say.

FWIW, I'd also blogged elsewhere--yes, on CF--prior to starting this one. And the first of those posts were in early 1998--so technically it's my 25th anniversary of blogging about CF. :-)

But about that dated site layout...

New updates released for Java 8, 11, 17, and 20 as of Apr 18 2023: resources and thoughts

It's that time again: there are new JVM updates released today (Apr 18, 2023) for the current long-term support (LTS) releases of Oracle Java, 8, 11, and 17, as well as the current interim update 20.

TLDR: The new updates are 1.8.0_371 (aka 8u371), 11.0.19, 17.0.7, and 20.0.1 respectively). For more on each of them, including what changed and the security fixes they each contain (including their CVE scores regarding urgency of concerns), see the Oracle resources I list below. Oracle calls them "critical patch updates" (yep, CPU), but they are in fact scheduled quarterly updates, so that "critical" nomenclature may sometimes be a bit overstated. And as is generally the case with these Java updates, most of them have the same changes and fixes across the versions as each other, though not always.

Note: If you use the JDK installer and may be coming to this update of Java 11 or 17 having skipped the last update, 11.0.18 or 17.0.6 respectively, please note there is an important change to the installer (for all OSs) which you should consider before proceeding. For more, see my discussion below.

For some folks, that's all they need to hear. For others, read on for topics like:

  • Finding more info on these Apr 2023 Java updates
  • What about other JVM distributions besides Oracle?
  • News for my CF audience (getting the Java updates from Adobe or Oracle, how to update, why you should NOT for now use Java 17 with CF, etc)
  • Should you apply the update? how soon?
  • Beware a change in the January 2023 JVM update regarding the JDK installer
  • Beware a change in the October 2022 JVM update regarding Java no longer trusting jars signed with SHA-1
  • Beware a change in the April 2021 JVM update, if you may be skipping over it
  • Wrapping up, getting more help
