[Looking for Charlie's main web site?]

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).

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

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

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).

Lots of upcoming ColdFusion/CFML-related events

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

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.

2016 in review: top 10 CArehart ColdFusion posts of the year

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).

Why you should think twice about leaving on the "public JRE" option of the Java JDK installer

This is a follow-up to a post I did in late 2014, CF911: 'Help! I've updated the JVM which ColdFusion uses, and now it won't start!'. In that post, I listed about a dozen common problems that befall people who try to update the JVM that CF is using (and it and this post apply as well to Lucee or BlueDragon, or indeed any Java application server).

In this post, I want to elaborate on one more common mistake. Well, mistake may be too strong word. It's about a default option when you run a Java JDK installer (see the other post for more on JDK vs JRE options).

In short, I make the case here for why you should NOT let the JDK installer implement its "public jre" option.

How to solve common problems with applying ColdFusion updates (in 10 and above)

While ColdFusion 10 and later releases add a new automated update installation mechanism, what do you do if the update doesn't work? The answer may be simple on the surface, but not obvious to most. (And you'll likely be in panic mode.)

Many find after applying a ColdFusion update that either CF won't start at all, or they can't access the ColdFusion Admin, or some part of CF or their app doesn't work. The problem may be simply that there was an error in the update process CF did, and it may be rather easily confirmed and resolved.

In this post, I share several tips and observations to help resolve this, based on my years of providing remote CF troubleshooting support.

The TLDR version: check the ColdFusion update log (not logs in the normal CF "logs" folder. More detail below.) And if there are errors, try stopping CF yourself and then either try the update again, or if it still fails, try to manually apply the update from the command line. If that's enough to get you going, great--especially if you ARE in panic mode! (If the "problem" you need to solve, instead, is that you can't get CF to show you updates because you're behind a firewall preventing outbound internet access, I help with that also, toward the end.)

For most people, though, even those "simple things to do" can prove challenging (and understandably so). And you may find different resources on the web offering perhaps truncated discussions of the topics, which is why I elaborate on things in this post.

And even if you're in a panic, it may take only about 10 minutes to read this whole post. (You can also hire me to help instead, of course. See the link above.) Hope the info to follow is helpful for you.

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.
