Using a RAM disk with Opera on OS X

Having recently configured AndroidStudio to use a RAM disk for Gradle, I thought I would look around and see if I can use the remaining space for Opera. This is essentially a reproduction of this fine page: http://www.ghacks.net/2010/10/20/how-to-change-the-opera-cache-directory/

That page does not deal with Macs though and after a little bit of experimentation I came up with this spell:
open /Applications/Opera.app/ --args --disk-cache-dir=/Volumes/RamDisk/opera
For the record, here is my Opera version:


Make sure that the specified folder exists before starting Opera, if might automatically create the folder for you but I didn't bother to find out, I hate disappointment.

And for the record, the way I create a RAM disk on my iMac, which is done automatically when I log in, is like this:
diskutil erasevolume HFS+ "RamDisk" `hdiutil attach -nomount ram://4194304`
The above line was courtesy of this YouTube video:

Thanks to Bartech TV then!
So, with Turbo mode on and a RAM disk, my late 2012 iMac feels well nippy again.

Sweet.

PHP and Lisp: multiple-value-bind (MVB)

This is another article in my attempts to find new ways of looking at PHP and making it less of a chore to type in all that code. As much as I love PHP I hate wasting keystrokes. More typing is more errors is more grief. Being an off and on user of Lisp, although not as much as I used to, one of the things that I always liked in Lisp was the ability to be able to return multiple values from a function at once using (values) and then marry that with (multiple-value-bind) to create convenient named bindings for whatever you were about to do. I recently found myself wanting to return a couple of values from a helper function and I just didn't want to go to the trouble of having to type all those character required to create an array with keys for the two values and then I remembered MVB and a little light went on in my head! If somebody else has already done this then I apologise up front but it was new to me and I haven't seen it anywhere else so this could be a first! ...

You are not here not reading this post...

Some days it's hard to really appreciate what a software developer is or does. And I have "been one" for over a quarter of a century and I still don't know what I do. I can translate management speak into meaningful English and then understand what "they need" as opposed to "what they think they need." I can translate "business requirements" into an internal mental model composed of data stores and processes and subsequently translate that model into "working code" in any language you care to mention to produce a "deliverable". But... I still don't truly understand what happened along the way. I think it is more to do with the underlying nature of the universe rather than the mechanical processes. Codds rules and normalisation for instance, one can learn, understand and apply these rules to great effect but what does "de-normalisation to 2NF" mean to a bunch of atoms and molecules which don't...
