Everyone agrees that Microsoft is not the really best when it comes to usability, right?
We've probably all looked at this dialogue at some point during our lives and said, "How about a No to All button, Microsoft?"
But did you know it's possible? Hold the shift key while you click the "No" button, and Windows will act as if there were a "No to All" button and you clicked it.
I'll be away camping this weekend, so if you're leaving comments on my awesome plugin posts and I'm not answering, that's why! I'll be back Sunday afternoon. See you then!
It occurred to me the other day, while filling out a CAPTCHA to leave a comment on a friends blog, that there is further room for improvement in most implementations, putting aside for the moment the fact that there are better alternatives. But if you have ever used a CAPTCHA before, chances are you've asked yourself this question: Is it case-sensitive?
And is it? Who knows?!
The solution!
Hardly anyone goes out of their way to indicate whether the CAPTCHA response is case sensitive, and, even worse, some even use fonts where the lower-case-L and upper-case-i — and this isn't the only set of easily confused letters — look essentially the same. As long as they're not getting spammed, that's good enough for them. Sadly, the solution is so easy that the careless among us are only hurting themselves. A simple CSS addition can make a world of difference.
Step 1:
Only use capital letters. This alone won't solve your problems, but capital letters are much more easily distinguished from one another in most fonts. Even if you don't have a nice pretty configuration screen for your CAPTCHA asking for a set of characters to choose from, I guarantee you it's in the code and would be a piece of cake to change. For example:
[viewcode] src="captcha.cfm.txt" showsyntax=no geshi=cfm[/viewcode]
Step 2:
Add a text-transform property to your CSS for the CAPTCHA response input field. Specifically, text-transform: uppercase;. This takes away almost any doubt a person might have over case sensitivity. Try it yourself; type some text in this box and see how much better life with CAPTCHA can be:
Extra credit:
Add a small line of text next to your CAPTCHA explaining that case doesn't matter. If you have the ability, choose a font with unambiguous characters.
This morning when I logged into GMail I saw this alert:
The "Fix this" link takes you to Google's Help Center page regarding the Firebug & GMail issue.
Sure enough, I disabled Firebug for mail.google.com, and it's been nice and snappy ever since. I emailed the same information to Ray so that maybe they can fix the root cause — if it's in the Firebug code and not the GMail code — instead of just creating this workaround.
God, I thought I was done with Perl. It always finds a way to resurface in my life, though, and I don't suppose that's such a bad thing.
On a debian server I'm running, I had the need to create an HTML file with links to a series of files in the same directory. With a couple of commands, this was cake!
First, list all of the files and save the output to an html file:
ls myfile* > myfilelist.html
This creates a file myfilelist.html with contents similar to:
