Weekend Cat Blogging: Snuggle
We recently received our “snuggle” from DKM (“Diva Kitty Mom”). It is black-and-white, perfect colors for both Luna and CatSynth HQ.
In addition to being a comfy place to sit, it comes with a special “treat”. The astute observer may see the catnip scattered on the surface of the yarn.
Luna took to this right away.
and seemed to quite enjoy herself. Indeed, she is quite fond of catnip. You can watch this video of the usually dignified Luna “nipped out” on her snuggle:
Weekend Cat Blogging #165 is being hosted by Pet and the Bengal Brats.
The Bad Kitty Cats Festival of Chaos is Sunday at Mind of Mog.
The Carnival of the Cats will be hosted by Samantha and Tigger (I believe Samantha just had a birthday).
And of course the Friday Ark is at the modulator.

Get Well Hendrix
Sending good thoughts for our friend Mr Hendrix, who was feeling rather ill this week. But he is doing a lot better now.
Plus, that is one of the cooler “get well” graphics we’ve seen on the Cat Blogosphere, so we had to post it

There is also a wallpaper-sized version on SYNTHWIRE.
For those who may not know, the Serge Modular Synthesizers are kits that can be assembled to build large custom analog synthesizers. There are classic editions, and new editions. You can visit matrixsynth for more images and info, or visit the unofficial fan site.

Weekend Cat Blogging: What Did You Eat?
Our friends Kashim, Othello and Astrid are dedicating Weekend Cat Blogging to our fellow cat blogger Sherry “Sher” Cermak of What Did You Eat?. She passed away suddenly last Sunday.
Sher was also an accomplished food blogger, and we have made some her recipes before. So in addition to Weekend Cat Blogging, we are also participating a tribute hosted by the “Bread Baking Babes” this weekend and preparing her last recipe.
So let us move to the kitchen and dining area of CatSynth HQ:
And with Luna ready to supervise, let us begin:
Angel Hair Pasta With Red Pepper Pesto
[Adapted from Food and Wine.]
3 medium red bell peppers or bottled roasted red peppers
1 tablespoon pine nuts
1 small garlic clove, smashed
1/4 cup basil leaves, plus 2 tablespoons chopped basil
1/4 cup extra-virgin olive oil
Salt and freshly ground pepper
1/2 pound angel hair pasta
1/2 cup grated pecorino cheeseRoast the red peppers over a gas flame or under the broiler, turning occasionally, until charred all over. Transfer the peppers to a bowl, cover with plastic wrap and let cool. Peel, core and chop the peppers. (We opted for the bottled peppers here at CatSynth.)
In a small skillet, toast the pine nuts over moderate heat until golden, about 4 minutes. Let cool.
Transfer the peppers and pine nuts to a blender or food processor (If your food processor has been sitting in a box at the bottom of a kitchen cabinet since moving, make sure to clean it first.) Add the garlic and whole basil leaves and blend until coarsely chopped. Add the olive oil and cheese and puree to a chunky pesto. Season with salt and pepper.
In a large saucepan of boiling salted water, add the pasta and cook until al dente. Drain and cool slightly under running water. Transfer the pasta to a bowl and toss with the pesto. Season the pasta with salt and pepper. Top with the chopped basil and pecorino and serve at room temperature.
Now let us raise a glass and toast…
More tributes can be found at Weekend Cat Blogging, hosted at Astrid’s food blog. I’m sure the boys won’t mind too much.
The Carnival of the Cats will be hosted here at CatSynth tomorrow. Click here to submit your entry.
The Bad Kitty Cats Festival of Chaos will be hosted this week at Pet’s Garden Blog.

The Fourier Transform of a Cat
We at CatSynth never miss an opportunity to combine mathematics and cats. Recently, our friends at Walking Randomly posted this image:
It was created by Andrew J. Bennieston, and inspired by this comic from xkcd:
Unlike the number theory and other mathematics we like to post here at CatSynth, the Fourier Transform is part of our stock and trade. There are many variants, including the Discrete Time Fourier Transform which one of the basic tools of signal processing and sound synthesis:
Basically, what a Fourier Transform does is decompose a signal (or any time-varying mathematical function) into separate frequencies. If you have a spectrum representation of a sound, this is output of a Fourier Transform. Similarly, if you have a graphic equalizer on your stereo, it can be seen as operating on a very low-resolution Fourier transform, as it allows one to raise and lower different frequency ranges of sound.
For images, “frequency” corresponds to detail. Highly detailed areas of image that change from pixel to pixel are high-frequency, while areas of constant color or intensity are lower frequency. Another variant of the Fourier Transform, the Discrete Cosine Transform, or DCT, is more often used with images because it tends to put more information in lower frequencies.
Theoritcally, one should not lose any information when taking a Fourier Transform of a signal (or image) and taking the inverse to retrieve the original. However, in Bennieston’s image, which applies two DCTs to the original image, results in the “ghost” that loses a bit of the original detail. Certainly, some is due to the rounding error when doing any calculations on the computer, but it seems like more than that. Most, likely, the DCT is more sensitive the boundaries, i.e., what happens at the beginning or end of a signal.
DCTs are often used in “lossy” image and audio compression, such as JPEG for images. However, I have rarely seen them used in music applications, where one tends to see more general Fourier Transformations, which correspond more closely to an intuitive understanding of musical frequency.
As such, it would be interesting to work with DCTs in a musical context and see what transpires. If we ever get around to this project, we will certainly post it here on CatSynth.
This post is part of the Carnival of Mathematics which is being hosted this weekend by Logic Nest.

CatSynth video: cat prelude
From subtone on YouTube, via matrixsynth:
Sounds a bit like a 1980s power ballad…or a music store from my deep dark youth (the two have a lot in common).
