Charlie Arehart offers new per-minute phone-based support service

Ever felt stumped trying to solve a CF problem? You've tried everything? Searched the web? Asked on forums and lists, and you're still stuck? Or maybe you're just pressed for time.

Maybe you've wished you could hire someone with more experience but can't justify a high hourly rate. Of course, with so many web tools available to share a desktop, travel need no longer be a significant issue. Sometimes, it could help to simply have someone "look over your shoulder" via the web to resolve a problem.

Recognizing all those challenges, I've created a new service that I'm tentatively calling "AskCharlie", to be able to offer just such assistance.

Via buttons on my site or an 888 number you call, you can arrange to speak with me by phone (and optionally join me in a shared desktop session) to solve some knotty problem.

Best of all, it's very low cost and at a per minute rate (first-time callers can use a 10 minutes free option, and everyone gets a money-back guarantee). That and more are explained on my site:

http://www.carehart.org/askcharlie/

There you can learn more about why I did it, how it works, how the remote desktop sharing assistance works (no problem with firewalls, for instance), and more.

I'd welcome your thoughts on what you think of the idea.

Suffering CPU/DB/memory problems in CF? Spiders, monitor pings, and more may be to blame

If you're trying to get to the bottom of high memory or CPU use or database contention on CFML servers, you may be missing a seemingly innocuous but deadly invader (or many of them, really. Many more than you may ever dream.) If you're focusing only on "what are my long running requests?" or wondering "Why does CF have a memory leak?", you may be looking at the wrong problem.

What if the problem isn't really a "leak" at all, nor "poorly performing code", nor "CF being unable to scale", but instead what if it's really all due thousands or millions of page requests, which (worse) are likely creating (unexpectedly ) thousands or millions of sessions and client variables, each day? They may even be something you're causing (but more likely not). It's a pernicious problem that many never even fathom, or may dismiss too readily.

Curious to hear more? Read on.

Interesting discovery from WebApper on CFSWITCH when used with strings, under load

The folks at WebApper have shared news of an interesting discovery regarding a performance problem they've observed when using CFSWITCH and a string value for EXPRESSION, especially in a loop under load. It seems interesting enough to make sure others notice it. Check it out.
