WebServer Monitor 1.0.7 Released

Category : Technology/WebServerMonitor107.txt

I've released WebServer Monitor version 1.0.7.

I've needed a way to quickly filter the log records by a visitor's IP address so that I can see how he has traversed through the web site. In order to do this, I've added a Navigation menu so that if you do a Command-Option-C, you can copy the log record's IP address to the Search Field, at which point the log records instantly shrink to show only those from the same IP address.

If you've sorted the columns by time, you can see how the visitor has come into the site, what pages he has looked at, for how long each page, and when did he leave.

Other items in the Navigation menu clears the Search Field (Command-Option-X), scrolls back to the currently selected log record (Command-T), and launches the referrer's web page (Command-R), which can also be done by double-clicking on the log record.

There's also the new "Check for Updates" menu item under the Help Menu that will bring you back to the WebServer Monitor web page, if I have a new release ready.

Actually, I'm thinking I could use the WebServer Monitor to be an Apache configurator, e.g., to set up WebDav, PHP, etc. Together with a log analysis tool, that's probably going to be the next improvements.

DNS Enabler 1.1.3 Released

Category : Technology/DNSEnabler113.txt

The domain name server now listens correctly to all its network interfaces on re-boot, and this seems to work reliably (about a minute after reboot). You can find DNS Enabler here.

The important thing is that the mail server gets its domain name correct when it refers to its name server, so that it can broadcast this correctly to other mail servers, rather than the xxx.local that it would otherwise report.

This increases the chances that its mail will get delivered. (Except for those picky mail servers that check further about whether its IP address is coming from a dynamically allocated block - something that I feel is beyond the call of duty).

Anyway, it's still an interim solution. It's neat because I avoided changing the system-supplied Launch Daemon plist, but it's at the expense of making the server check a lot more frequently for changes to its network interface.

But, at least the system is now working like a name server should.

There is a Check for Updates menu item in the Help menu so that you'll get to know if there's a new version out. And this will be added to all the other stuff we're doing, like Postfix Enabler, WebServer Monitor. And Luca.

"He who's not busy being born, is busy dying"

Category : Commentary/busybeingborn.txt

"He who's not busy being born, is busy dying". That's Bob Dylan, and I wrote about this sometime back in connection with a book I was reading then, "The Creative Economy - How People Make Money from Ideas" by John Howkins.

I picked up Andy Grove's book, "Only the Paranoid Survive" from my book shelf, turned to the back cover and, whaddaya know, there's a blurb from Steve Jobs. (This book came out, let me see, in 1996.)

"This book is about one super-important concept. You must learn about Strategic Inflection Points, because sooner or later you are going to live through one." - Steve Jobs, CEO, Pixar Animation Studios.

So, what is this Strategic Inflection Point of which he speaks? From the jacket notes :

"Grove's contribution to business thinking concerns a new way of measuring the nightmare moment every leader dreads - the moment when massive change occurs and all bets are off (italics added). The success you had the day before is gone, destroyed by unforeseen changes that hit like a stage-six rapid. Grove calls such moments Strategic Inflection Points, and he has lived through several. When SIPs hit, all rules of business shift fast, furiously, and forever. SIPs can be set off by anything: mega-competition, an arcane change in regulations, or a seemingly modest change in technology.

"Yet in a watchful leader's hand, SIPs can be an ace. Managed right, a company can turn a SIP into a positive force to win in the marketplace and emerge stronger than ever."

Apple is heading into one such tornado. And Steve Jobs looks like he's prepared.
