I've made may first directive! OK, not that special, but to me it is. This is one of the more difficult features I've come across in Angular, and I still don't really "get it".
I'm not even going to do a code walkthrough, because I can't really explain it well. The easy part is calculating the height the element should be. The tricky part is implementation.
I have to learn the Chromium bug reporting system. Found an interesting rendering bug if, on a label, you specify a padding with an even number of points (pt), the rendering is shifted up a little bit, and the border can disappear if it's adjacent to another element.
Two examples are attached, differing only in the amount of padding.
Maybe it's a difference in how the values are calculated and either rounded off or truncated.
The problem goes away if you use pixels instead of points.
This code puts the first paragraph of the post into the description meta tag. It tries to strip out leading whitespace and any tags. If you insert an image, it should be stripped.
I'm learning R, and it's been interesting. The weird part is that I don't know stats. Yes, I know standard deviation, mean deviation, and easy stuff, but those are one-liners in the R tutorials. What I know in stats amounts to around 1/4 to 1/2 a page of the R tutorial. So to compensate, I have a stats text from the thrift store, so I'll eventually be less than a total ignoramus about what I'm reading.
One of the twists of what I'm messing with is that all our data is in a database. The normal mode of operation for R users is to load the entire data table into memory and do awesome reporting on it. Where I'm at, for better or worse, is more like a traditional web application with a database back end.
A problem with this is that MySQL lets me have only 16 connections going at the same time. I'm not sure if it's the driver, but I'll assume that. Since RStudio holds the connections, coding a lot of changes eventually leads to a lot of lost database connection handles, and eventually running out of connections.

In Ubuntu Linux, the path to the global libraries is: /usr/local/lib/R/site-library/
To install there, you can do install.packages(c('foo'), '/usr/local/lib/R/site-library/')
or take advantage of the built in variable: install.packages(c('foo'), .Library.site)
Check that .Library.site has the values you need.
You can also use R CMD INSTALL -l /path/to/library foo
A short article explaining how to improve your experience and produce slightly better code.
URLs: it's important to define your URLs rather than exposing all your PHP files to the world.
Use routes - study the one in ZF2 but don't copy it unless you really need it. CodeIgniter's is pretty nice too. Routes help map URLs to classes and methods.
If you don't want to use routes, use Apache's mod_rewrite. It's faster, and also awesome. It tranforms specific URL into specifc requests to specific scripts.

Dang, but it took me forever to learn CSS. Maybe I should have used a book. Here, I'm going to share with you the hard-found knowledge, presented using technical programmer jargon. (Revised in 2014.)
What is Cascading Style Sheets (CSS)? The typical answer is that it's a way to separate the way a page looks from the the underlying HTML, which describes the structure of the document.
This snippet of code can be modified and used to change the stylesheet on your page. I set it up to work against a layout extracted from Salsa, but it should work on generic pages. It's good for demos, discussions about a layout, trying different colors, etc.
This is one of those "why bother with an external library" moments. Mostly copied from MDN.

I got the ezmlm migration working, which is cool. Mailman and mail migration will be easier. So I took a day off. (Web migration will be a headache.)

I'm not much of a Python coder, but I'm learning to be a pretty good Python re-coder.
Mobile websites all seem to have this button, which appears when you've scrolled down a bit. The button scrolls you back to the top of the page, where most of the menus reside.
This seems so basic, it's almost embarrassing to publish, but this showed up a few times on Stackexchange. I had trouble figuring it out, too, partly because the Python docs are so lengthy.
