Solving technology problems, one at a time
The other day I tried to load a URL in Safari that has worked dozens of times before, but now Safari prevented it from opening entirely, instead presenting this dialog: The website “[my requested URL]”

While experimenting with LDAP connections in Safari, errors like this one started popping up:
“The website _____ requires a client certificate”
A dialog would open, listing some old MobileMe certificates. Apparently if any old, expired or corrupt MobileMe certificates are still lodged in the Keychain, you may get this error sometimes. MobileMe has been disabled and signed out on my Mac for years, but the fact that the certs were still there caused the problem.

There have been a few interface updates to Amazon’s Kindle page since I last wrote about it, but there remains a strange lack of comprehension on the part of Amazon, that people might actually want to use their highlights. There is still no obvious way to export the data.
For those with Macs, I’ve come up with a workaround, and perhaps there is something similar on the PC side.

Safari is one of the biggest offenders, and it appears the problem is at least partly from lack of free memory. If Safari starts crashing everytime you open it, it sometimes helps to close all apps in the multitasking bar.

"Webpages are not responding. To visit the selected webpage, all webpages in other tabs and windows must be force reloaded. Do you want to visit this page?"
Once this error shows up, usually several windows will start reloading on their own. The error seems to happen only when I have a lot of tabs and windows open in Safari, but since I almost always do, it’s hard to pin that down as a contributing cause.

I find the new debugging tools in Safari almost as useful as Firebug. There’s a Web Inspector that lets you see exactly how the HTML is formed, a Javascript console that lets you see errors and debugging messages written into the code and much more.
But to use them you must enable the Debug menu in Safari. Open Safari preferences in the Safari Menu, click Advanced, and select Show Develop menu in menu bar.

The z-index bug in action
Although Internet Explorer 8 has been widely adopted, IE 7 is still the browser in use at my office, so all new projects must be compatible with it. Even though IE7 was already obsolete when we adopted it, it was a wonderful change from IE 6, because of the reduced need for CSS and javascript hacks, workarounds and compromises in general.
So it was a surprise to realize that an old Internet Explorer 6 stylesheet problem, the “z-index bug” still lingers on. You’ll know you’ve hit this bug when your drop-down menus fall UNDER elements that are lower down on the page. (…I should add: and there are no iframes or frames on the page).
There are several sites that do a fantastic job of telling you exactly why this happens. I’m just going to tell you how to fix it. In fact, if you want to jump to the fix right now, click here
Continue readingI’ve been using DimDim lately to share screens and host impromptu meetings. I recently hosted a three-person meeting for the purpose of screensharing an application we were all working on. Previous meetings of this type had gone well, but this time we kept having problems with “Another meeting room running” errors which prevented screensharing.
