    <p>My current (spare-time) project: <a href="https://github.com/lukeu/TracInstant" rel="nofollow">TracInstant</a> </p> <p>If I could get to shake one person's hand: Doug Lea. For pushing the boundaries of concurrency yet making it accessible to all via object oriented code. I can't help but smile each time I look into <a href="http://www.jarvana.com/jarvana/view/backport-util-concurrent/backport-util-concurrent/2.0_01_pd/backport-util-concurrent-2.0_01_pd-sources.jar!/edu/emory/mathcs/backport/java/util/concurrent/ConcurrentSkipListMap.java?format=ok" rel="nofollow">ConcurrentSkipListMap</a>: absolute insanity and pure beauty, superimposed.</p> <p>If I still had time for myself, I'd probably be playing with physics simulations, or real-time dynamic-control &amp; autonomous flight with quadrotors. (Looking forward to time &amp; excuses to play around once my kids are a bit older!) </p> <p>Interested in numerical algorithms, user interfaces, parallel algorithms. Past interests in 3D graphics, machine vision &amp; I've <a href="http://bettyluke.net/Projects/01_04Power.htm" rel="nofollow">dabbled in Electronics</a>.</p> <p>I cut my first code on a ZX81, then Spectrum. Proudest early achievement was a crude 3D renderer on an Amstrad CPC 464, could fly around in wireframe &amp; then do a polygon-fill paint. (Oh, but the 3rd degree of rotation! Who would have guessed I needed a 4x4 matrix... I didn't even know about matrices.) My code was of course rubbish, but I've been striving to improve that ever since... :-) I'm not sure this process will ever end, as practices in the whole profession continue to evolve, which is nice to see &amp; be part of.</p>

    1. COIs this an assignment? I spotted someone else posting just this question again in Nov 2013! (Before deleting it) If not, then you don't need to open-code it - so just use `Pattern.compile(Pattern.quote(needle).replaceAll("_", "\\\\E.\\\\Q"));`

    2. CO<font> is one of those pedantic tags that technically needs to be re-specified inside many other tags - you can't just wrap it around the outside. So this solution is too brittle for general content.

    3. COThanks for writing that @mik1! Very informative, clear and up-to-date article. (I came back here intending to post a link to it myself.)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.
