Every cat is unique. Much like human individuals. And, much like human individuals, you don’t necessarily want to hear about the quirky behaviors of ones that you’re not taking care of. If that’s how you feel, you might want to skip this post. (Of course, if that’s really how you feel, you’ve probably already unsubscribed from this blog.)

Mr. Alexander the Great has his likes (regular mealtimes, burrowing under carpets, laser pointers, cuddling) and they mostly make sense.

His dislikes, however, are harder to explain.

My Cat Hates Linear Algebra

He may have been objecting specifically to the mathematical contents of Brand (2006) “Fast low-rank modifications of the thin singular value decomposition” but I have no way of knowing for sure.

My Cat Hates Café Bustelo

Can’t blame him, Tucson has much better options for coffee.

My Cat Hates Feet

Right there with you on that one buddy

My Cat Hates People Outside of Windows

Cat physics cannot explain how humans pass through solid walls, and prescribes but one acceptable reaction: a good hiss.

Let you think this is a fluke, he reliably hisses at anyone who approaches his window nook. Here’s another.

Most of all, My Cat Hates Cameras

Bad experiences with the paparazzi?

Of course I haven’t got the photo and video material to cover his dislike of:

• any and all cleaning implements with handles
• the Roomba™
• crinkly bags (except when he crinkles them himself)
• sudden noises
• sudden silences, and
• being asked to leave the bathtub so that I may use it.

You’ll just have to take my word for it on those.

Song of the Day

This cover of Billie Eilish’s “Bad Guy” seems appropriate. Somehow the horn part alone makes it more compelling than the original synthpop.

Make your own “Bad Guy” at home from simple household ingredients, courtesy YouTube Person Seth Everman:

(There’s always The Original, if you’ve somehow managed to avoid hearing it before. Here you go.)

It’s back-to-school season, but it doesn’t look much like last year. It’s even hotter, for one thing. (Also, to be quite honest, I still feel like it’s March.)

The State of Arizona has decided to contain the COVID-19 pandemic by topping national headlines for “worst COVID-19 outbreak” until we all stay indoors (from shame, one assumes). Bizarrely enough, it appears to be… working?

Full disclosure: I’m technically an employee of the State of Arizona. Unless I’m a student. (I’m told “it depends”.) In any case, my views are my own and this post is being brought to you without use of University equipment in compliance with all applicable policies.

Out of an abundance of optimism, the University has decided to welcome students back for the fall (with some caveats). Of course, we were here all along. In addition to Vizzy tricks and text message measures, we have been regularly sanitizing all surfaces touched by lab workers and employing low-tech signage to keep the coronavirus out of our lab.

Of course, sterile (heh) line drawings are less compelling and eye-catching than putting a human face on the instructions. But whose?

Is there anyone whose mere appearance causes graduate student rule-compliance to skyrocket while simultaneously boosting mood and job satisfaction?

That’s right: Dr. Jared R. Males.

Of course, photoshopping one’s advisor is not without precedent. Anyway, none of our lab equipment has caught the novel coronavirus yet, so it seems to be working.

Plus, I think he likes it.

Thanks to Lauren Schatz for her assistance in hanging signage and photographing mischief.

Your Song of the Day

Your song of the day is “Crawl Out Through The Fallout” by Sheldon Allman.

I know what you all are thinking. We have hit triple digits in the number of days since this all began and Lauren still hasn’t made a blog post just about her cat. Don’t worry it is time to right this wrong, and what better time do to so than for Katniss’s 5th birthday!

I’ve heard of a wise philosophy that you should take any excuse to party. This year I decided to throw my cat a birthday party.

The preperations for her birthday began about a week before the party. I decided that since it was her special day, she should have a special outfit to wear. I picked up some cotton fabric at JoAnn’s and made her a little birthday dress. This was a great excuse to try out a ruffler pressure foot for my sewing machine. It is a neat little device that automatically pleats your fabric at a stitch interval of your chosing.

Once that was done the next part of party planning was to send out the invitations. Under normal circumstances, I would have loved to invite you all, but due to social distancing I kept the gathering small. Sorry you all missed it.

The last step was decorations. I went minimalistic this year, and bought two balloons from the dollar store.

They were a big hit with the birthday girl.

Now that everything is set it was time to party! We did Korean bbq on some tabletop griddles…

… forced Katniss to wear her party dress …

… and then ended dinner with some birthday cupcakes. I had to help Katniss blow out the candles.

But what would a birthday party be without presents? Katniss really got spoiled this year, Logan made her an abosultely amazing cross stich, and she got some treats from mom.

Happy birthday Katniss! Hope you all have an excuse to party before the end of summer 🙂

Bonus Content: Katniss’s Origin Story

Katniss and I go way back. So far back, that I knew her mom as a kitten! Katniss was born on July 27th 2015 to single mom Legalos. Legalos is the cat of my friend in my hometown. I remember when she was a little kitten, and when she grew up to be a beautiful cat. So beautiful that I said off handedly that if the cat ever had kittens I would want one. My friend remembered it, and when irresponsible teen Legalos snuck out of the house and came back pregnant, I was first in line for one of the kittens. Katniss was born in a litter of two, just her and her brother.

So we know who the mom is but who is her father? My friend and I like to think her father was a cat we called Mountain Cat. He was a brown Maine Coon mix that belonged to my friend’s neighbors. The neighbors for a while were landscaping their front yard, and almost everyday my friend and I would see Mountain Cat sitting on top of the mountain of dirt in the front yard. Hence the name Mountain Cat.

When I first met Katniss she was a little bit older than the photos shown here. About two months old. She wasn’t quite ready to be seperated from her mother, so we decided to wait until Thanksgiving for my mom to drive her across the desert to me when she was visiting for the holiday. Below is the first picture I ever took of Katniss on her first night at my place. She was already making herself at home!

And this is the first photo I ever took together with Katniss!

To end I will share some fun Katniss facts:

• She looks cross eyed but it is only one eye that is derpy.
• Her goal in life is to be as chonky as possible.
• If you walk past her while she is eating she will sad meow at you, and put on a very concerned face as if you are going to take her food away. Despite the fact that never once in her life has food ever been taken away from her.
• Her favorite thing in the world is her most beloved wet food treats.
• Everyday when I come home she runs up to me, starts meowing, and will only stop when I pick her up and give her a hug.

Song of the day: Some relaxing vibes

The University of Arizona is resuming some in-person research lab activity, subject to restrictions to ensure safety and social distancing. We are to log our comings and goings, continue sanitizing surfaces, limit the number of occupants in the lab, and generally stay home as much as possible.

Years ago, our P.I. articulated his vision for MagAO-X development as “doing as much work as possible from home, with a cat on [his] lap.” I’m happy to report we’ve more or less achieved that! Everything but the fanciest of the deformable mirrors (previously) can be safely powered up and fiddled with remotely. (And there’s a plan to make even that possible.)

How do we do it, you ask? Well, our instrument software is a bit tricky to set up, but we use Vagrant to allow everyone on the team to get a virtual machine that approximates a fully set-up workstation. Initially this was to enable running our applications on non-Linux computers, since some of them depend on some rather obscure Linux-specific details, but it’s proved useful to automate setup across the board.

Thanks to virtualization, I even believe we have the world’s only extreme AO system that you can run on Windows!

(Please don’t.)

After following the setup process, I can simply vagrant ssh and use my virtual machine to pop up the MagAO-X GUIs on my MacBook Air at home for controlling the real instrument in the lab:

Everything here is absolutely essential. Let me walk you through it:

On the laptop monitor, our Slack #lab-activities channel is open for coordination of in-person and remote work on the instrument. I recently taught our viscachabot, @vizzy, to update the official Google Sheet for lab check-ins based on their messages:

On the larger monitor, in the top left we have a couple instances of rtimv, the RealTime Image Viewer showing data from the pyramid wavefront sensor and one of the two science cameras. The bottom left quarter holds the web interface (previously) for toggling things like filter positions, stream writers, and shutters. The bottom right holds the power GUI for toggling things on and off with our network-controlled power strips. The top right GUIs are for deformable mirror and pyramid wavefront sensor control.

Above the screen, a webcam is perched for (what else) Zoom meetings. At right, a desk fan to attempt to maintain operator comfort despite Arizona summer. There’s a can of fizzy water, for similar reasons. (I blame Las Campanas Observatory’s now-discontinued habit of stocking bottled fizzy water for getting me addicted.) If you look closely, there’s even a rubber duck for debugging.

It doesn’t look quite as nice as MegaDesk (seen here at first light) But it’ll do in a pinch, in a pandemic.

Of course, there is a lot of work going on behind the scenes—not only to make this virtual machine work, but to keep the process documented and working for new members of the team. For instance, our instrument computer setup process is mostly automated, and we run it in The Cloud™ every time we change our instrument software to ensure everything still installs cleanly.

Song of the Day

A friend of mine put together a playlist of French-language music and I quite enjoyed this one. No thematic connection. (Anyway, I don’t think there is… but I don’t speak French.)

Your song of the day is “Calvaire” by spill tab:

Postscript: Spooky action at a distance

“Spooky action at a distance” is famously how Einstein described quantum entanglement, but he never used the English word “spooky” that we know of. According to this answer on the History of Science and Mathematics StackExchange, the quote originates in Einstein’s letter to Max Born where he used the German word “spukhaft” to describe entanglement.
