BUT, the OEmbed code isn’t Valid XHTML. I always strip out the code.

Comment on UTF-8 and MySQL by miqrogroove

> I checked the documentation for MySQL Connector/J (the JDBC driver), and it says that the connection is UTF-8

I just surfed in and noticed your DB problem here. Actually, your MySQL Connector encoding was the original cause. If you had ensured the text in the scripts was UTF-8 and forced the connection to match the single-byte (latin1) encoding of the DB table, then you would have had a binary-safe storage layer.

What threw you off track here was changing the table encoding to UTF-8. As soon as you did that, it became necessary to guarantee everything between the script and the table was UTF-8 as well, to prevent implicit latin1-to-UTF8 conversion. (That conversion is bad for binary data)

On the bright side, now all of your string columns will use chars instead of bytes

Comment on One instance at a time with PID file in Bash by Gerard Seibert

I modified your script slightly. It works on Bash and does not create a ‘1′ file. Using the ‘f’ flag with ‘rm’ also prevents useless error messages.

PID_FILE=”/var/run/my_prog.pid”

## Check to see if the program is running
if [[ -e ${PID_FILE} ]]; then
## Capture the ‘pid’ number in ‘pid’ variable
pid=$( ${PID_FILE}

do something

## Remove the pid file if it exists
if [[ -e ${PID_FILE} ]]; then
rm -f ${PID_FILE}
fi

Comment on Compression (deflate) and HTML, CSS, JS Minification in ASP.NET by Tim Meers

Tim Meers — Sat, 07 Nov 2009 02:07:42 +0000

Hmm, just got a chance to test this out. It works good but it’s actually breaking my Asp.Net AJAX and keps it from loading and finding my ScriptResource.axd files. I’d love to drop the toolkit, but for the time being it’s going to stay put. Any ideas on how to correct, or did you not see this issue? Oh and btw, it compresses my page source from 48k to 9k, crazy fast loading times, just wish it didnt break the toolkit.

Comment on HTTP Caching Header Aware Servlet Filter by Alexandre Victoor

Thanks for this filter.
I think there might be a concurrency bug : SimpleDateFormat is not a thread safe class, getHttpDate() and getDateFromHttpDate() are synchronized but could be called by two different threads at the same time…

Assuming you’ve stuck to good HTTP design (ex GETs don’t modify data), you can use this filter for all pages, so everything will benefit from the additional headers and caching.

Hi Craig, how do you suggest map this filter in web.xml? just for pages that i want or leave for all pages in my web application?
