Mac Maintenance

Here's Apple's recommended maintenance:
Mac Maintenance Quick Assist
  1. Keep Things Up to Date
    Make it a point to check for Apple software updates once a month
    No problem, I have it set to check automatically
  2. Put Your Files Away
    Put your files away where you can easily find them.
    A question about email attachments: should I just keep the email and attachment, or save the attachment and delete the email?
    My habit has been to do both: if I sure I want the attachment, I will save it to a sensible location.
    The problem comes with attachments that I can't use immediately, but don't want to throw away either. I have at least 150 M of such stuff.

404s fixed

We moved a folder:
but search engines are still looking for the old URL.

How to fix this?

1. create a text file called /training/reacademy.php that contains:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"
<meta http-equiv="Content-Language" content="en-us">
<meta http-equiv="content-type" content="text/html;charset=iso-8859-1">
<title>Tech Transfer Resources</title>
<meta http-equiv="refresh" content ="0; URL=">
<body bgcolor="#ddeeff">

<h1>Please Update Your Bookmark</h1>

The page you accessed has been moved.
If you are not automatically redirected to the new location,
please click <a href="/reacademy/">here</a>.
Please update your bookmarks or favorites.
But, this gives log lines like:

"GET /training/reacademy HTTP/1.1" 200 673 "-"

If we want the crawlers to know the URL is no good, we need to send a 301 - Moved Permanently, so this is better:



Which gives:

"GET /training/reacademy HTTP/1.1" 301 5 "-"
"GET /reacademy/ HTTP/1.1" 200 23730 "-"

(According to
Unless the request method was HEAD, the entity of the response SHOULD contain a short hypertext note with a hyperlink to the new URI(s).
So I also included the html as above, minus the "refresh" META tag.)

Price added to freestuff item?

I lurk on most outward-facing email lists for our department. Today I saw a confirmation email from G3 (free stuff) with this:
SKU18 Inspector's Job Guide and Highway Maintenance Tables $6.00 6 $36.00

I emailed the list to point this out.

ssh tunnel

I always have to look this up:
ssh -L 8888/localhost/8800
The parts:
the secure shell command
your account on the host to which you want to tunnel
ssh forwarding (tunneling) flag
local port (could be 8800 in this case, just needs to be unused on your machine)
your machine
port on remote host
then in (for example) your browser, you can enter the address
and get the page at

fixed in: /sitemap/index.php


I also fixed a LOT of broken links in older newsletter folders (.html instead of .php, old paths that were replaced 3 or 4 years ago...)

Newsletters from late 2006 and all of 2007 didn't have index.php pages, so I copied HTML from the newsletter/archive page into new index pages for each issue in 2007. Still need to do 2006.
