Feed Glom

Sometimes you want to quickly produce a new RSS feed out of a bunch of existing RSS and Atom feeds.

Here is a really simple way to do it in PHP: feed-glom.zip

This uses the atom2rss library by porneL.

Prefetch Files on OSX

OSX has some pretty nice features for optimizing access to frequently-used files; it preferentially caches and defragments them and places them on the faster part of your disk; this is especially apparent if you have a Fusion Drive (hybrid HDD/SSD). However, OSX provides no mechanism for forcing files to be handled in this way; you just have to access them a whole bunch and hope OSX gets the picture.

So, if you want to quickly force OSX to do this, you can use this very simple Automator script, which just forces OSX to read the contents of whatever directory or bundle you drag-and-drop into it 5 times. This is especially useful for optimizing file access to large media projects in apps such as Final Cut, Logic Pro, and so on. If you use Logic and get the dreaded "audio system overload" or "disk too slow" errors, try dragging your project folder in and see if that helps.

This doesn't actually change any file contents; it just scans through them so that OSX knows that you really want to access these files particularly quickly.

Note: This will only work on folders and bundles. It would be relatively easy to make it work on individual files if enough people want it, but there isn't as much use for that.

VCard phone number normalizer

These days, it's no longer good enough to use local phone number formats for your address book; you might be trying to dial someone via SIP without any clear locale information, for example, and so trying to dial a 10-digit US number might end up routing the call to some other country, which can be quite embarrassing.

Further, in this day and age, you might actually be travelling between different countries, and so you can't really predict what your outgoing call routing will be like!

So, here's a really simple C++ program that wraps the Google libphonenumber to normalize the phone numbers in a .vcf file (used by most modern address book systems) based on your current locale.

See the code comments for usage details.

AudioCompress

AudioCompress is a gentle, 1-band dynamic range compressor intended to keep audio output at a consistent volume without introducing any audible artifacts. It's intended to be used as a pipe in a filter chain, but also works as an ESounD filter, and as a library it can also be embedded into applications such as media players. more...

HSV color transforms

Because the need for color manipulation comes up fairly often in computer graphics, particularly transformations of hue, saturation, and value, and because some of this math is a bit tricky, here's how to do HSV color transforms on RGB data using simple matrix operations.

Note that this isn't for converting between RGB and HSV; this is only about applying an HSV-space modification to an RGB value and getting another RGB value out. There is no affine transformation to convert between RGB and HSV, as HSV is not a linear color space.

Mr. Chaney

Mr. Chaney — simple Markov-chain dissociation engine. Great for writing chatbots or spamming Slashdot experimenting with procedurally-generated discourse.

randline

randline.cc — exceedingly simple commandline program to randomize the order of lines in a text file. Great for generating playlists or whatever.

xmousekeys

xmousekeys.c: a simple program for moving the mouse cursor around from a script. Useful as something to bind to a key event in window managers which allow such a thing but don't have built-in keyboard-mouse functionality (such as pwm).
