This blog post was titled—somewhat optimistically—earlier today, but rest assured, dear reader: MagAO-X is even more alive now than when I wrote that. There is a polemic I could write about the Linux kernel’s casual attitude toward hardware support, but the short version is: we got everything reinstalled and connected and closed the loop in lab this evening on 1,564 modes.
As you may have heard, our Instrument Control Computer was supposed to get a software remodel, but instead ended up with the equivalent of a spit-shine and a new coat of paint. (One can imagine worse outcomes.) The best efforts of our hardware partners to provide Linux support were no match for Linux itself, which continues to defeat all comers in its ability to break software that once worked.
On the plus side, I hear the new way to write drivers is, like, super convenient. Shame about all those old drivers y’all have.
The highlight of the day (other than the loop closing thing) was the arrival of Eva and Lardy:
This afternoon a van disgorged a Professor Lardy Clos (optomechanics lead, natty dresser) and Eva Maklaod, soon-to-be-Ph.D. student in the XWCL.
It was a bit disappointing to spend all that effort on the computer upgrade and then roll it all back, but getting here early means I’ve run out my quarantine days already. And that means I’m allowed in to the dining room to dispense cappuccinos from the fancy machine, and that is an outcome worth celebrating on its own.
The third most exciting thing to happen today was spotting this neat bug:
Song of the Day
A review of the blog archives (blargchives?) revealed that nobody had ever used 2000s classic “Bring Me To Life” by Evanescence as a blog post Song of the Day before. (Jared didn’t believe me.)
“Bring Me To Life” by Evanescence
Required Song Context Per Rule 2023A§5(c): It is hard to pinpoint when I became aware of this masterpiece. To date myself (and/or upset my elders) I was a melodramatic 13 year old when it came out. That alone is reason enough to resonate with the subject matter. (Wikipedia research reveals the songwriter was 19 when it was written, which tracks.)
Per the blog rules I should explain a memorable occasion when the song was played, but “being 13” might not cut it. Instead, I offer the following important facts:
“Bring Me To Life” reached #5 on the Billboard Hot 100, but #1 on the US Alternative chart. (And was the number one song of the year in the Australian Rock charts, what the heck.)
The sudden dude energy that kicks in at 2:50 in the song was apparently due to record executives being too chicken to release a song with female lead vocals and heavy guitars. I always thought it was incongruous and now that all makes sense.
I have just learned that it served as the official theme song for WWE’s 2003 No Way Out event, a totally normal stop on the route to international fame.
Jared and I traveled to Las Campanas Observatory over the last 24 hours, and we’re finally ready to relax get things ready before the rest of the team rolls up. Also, the travel day blog has unofficially served as the repository for surprises, changed policies, and caveats for travelers in These Unprecedented Times—so I better get them written down before I forget.
Most of the tips from the previous Day 0 post remain valid. We did, however, see some people randomly selected for post-arrival COVID-19 tests this time.
Tucson
Documentation exigencies were the lowest since the beginning of the pandemic, with only the usual passport check required. (I did hand over my vaccine cards in my passport, so I guess the agent knew I had them if needed, but no online pre-approval is required any more.)
The TUS-ATL leg was uneventful, aside from some drama wherein the Delta reservation system informed Jared that, not only was he being “upgraded” to a middle seat, but it was because his profile in the system indicated an expressed preference for middle seats. (“Said no one ever,” as the saying goes.)
I also got “upgraded” the night before and was able to switch it back quickly, but something’s clearly awry in the Delta system. Double-check your seats before you show up!
Atlanta
The Atlanta layover was uneventful, but we did notice another system malfunction: The Plane Train between terminals at ATL was in a reboot loop. We lacked the foresight to capture it for the #blog-ops channel, but apparently it does this a lot and Reddit had evidence.
Don’t worry: it was only the informational displays that were on the fritz. We did not end up stuck on a ghost train.
Also, the Atlanta gate agents were the ones who could get Jared his preferred seat back. Hooray for solving problems (of their own creation)!
In the air between Atlanta and Santiago
The new Airbus Whatever that we flew on for the long haul Delta flight from ATL to SCL was pretty dang nice. By making the seat backs paper thin and rigid they somehow seem to have increased legroom in main cabin. And I didn’t notice the chairs being less comfortable—notably, they’re more comfortable than the LATAM flight I took from LAX to SCL for 2022B.
Also, I recommend flying on a Tuesday; it seems to maximize your chance for an empty middle seat in your row. The aisle seat was occupied by a Brazilian dude named Victor who had relocated to Chile by going on vacation and never returning, then gotten a job in the Chilean embassy in DC, and now lived in Arlington, Virginia. If he is to be believed, he had previously worked not only as an embassy staffer but also as a crane operator at a mining camp in Chile and as a LATAM flight attendant, and he had quit the embassy gig to pursue some self-employment hustle.
He also said Chilean food was amazing and his favorite thing about the country. No lies detected.
Santiago
Clearing customs was uneventful. After customs, if you head left down the hall with the taxi stands, there is a LATAM recheck counter. We usually ignore this and take our bags across the way, but today we had a minor surprise: they would not accept Jared’s bag for check-in at 8:30 AM for a 1:00 PM flight. They relented after some convincing, fortunately. I, on the other hand, had re-checked my bag with the LATAM agent after customs—sparing me both the schlep and the kvetch.
Note that without LATAM “priority” (i.e. Delta loyalty status) there could be a long line to re-check bags after taking them across to the domestic terminal, which is another argument in favor of re-checking after customs. (An argument against is that the bag re-check agent in the basement is always the slowest person LATAM has working on any given day.)
The Santiago airport layover otherwise provided its usual limited selection of amusements: McDonalds and Starbucks. The McTrashcan was out of order, however.
There was also some more software gore in the ordering kiosk. Surely nobody would want to use the English interface and pay with a card, right?
After several tests, exactly one pair of working outlets was identified at the corner of the Starbucks seating area against the window, near the boarding door for the adjacent gate. (We wish you luck in securing them.)
La Serena
The flight to La Serena got a little loopy. Nothing to worry about, unless you’re operating on few hours of sleep and wondering if you got stuck in a time loop.
Once we got out of the holding pattern, we were on the hardstand in minutes.
[I had a selfie to include here but upon review I look way too tired.]
After retrieving our bags from the (only) baggage carousel, we were whisked away by Sol del Valle Transportation in a well-appointed minivan. La Serena delivered street art as usual:
The transport from La Serena to Las Campanas got us in around 5:30—to the paramedic station, to get our nostrils swabbed. They appear to have shortened the swabs themselves, effectively discouraging the nasopharyngeal gouging ritual that had been the standard in the past.
This paramedico is my new favorite!
Jared R. Males, Ph.D.
We aren’t nearly as well supplied for our three-day bubble-mode this time. I didn’t even have a mug provided to use with my coffee pot! Fortunately, I brought my own:
So, there you have it. Tucson to Las Campanas in 24 easy hours. Time to collapse.
Song of the Day
There is no rule this time that the Song of the Day must be thematically appropriate, but we did just Get Out of Tucson…
Song of the day provenance and context: I’ve long been a fan of CHVRCHES, and I saw CHVRCHES perform this in concert in Tucson with lab alumna Dr. Lauren H. Schatz, Ph.D. back in 2019.
MagAO-X and the eXtreme Wavefront Control Lab are affiliated with the Alien Earths project, an interdisciplinary collaboration led by Dániel Apai. I was going to list off the disciplines that they are inter-ing, but they said it best on their website:
Our Alien Earths team includes experts in planet formation, exoplanet detection and characterization, planet formation, planetary atmospheres, astro- and cosmochemistry, meteorite and asteroid sample analysis, planetary interiors and atmospheres, and mathematical biology and ecology.
This week, they are holding their all-hands meeting in Tucson.
We are contributing a whopping five talks to the program, giving us a chance to not only overwhelm them with our direct-imaging jargon, but also keep it up over multiple days.
As a prelude of the coming flood, Logan Pearce gave our science and instrument status update early in the Wednesday program.
“Après moi le déluge” — Logan, probably
She also took the opportunity to advertise the MagAO-X Sirius-Like Systems Search (final logo pending):
After lunch, Sebastiaan Haffert gave an update on direct imaging plans with the upcoming Giant Magellan Telescope and the planned GMagAO-X instrument our group is developing.
Lest you think we gave every talk at this meeting, rest assured that there were other people on the schedule. (Organizer Dr. Kevin Wagner thankfully spaced us out so we wouldn’t overwhelm people.)
However, this is the Extreme Wavefront Control Lab blog, and we don’t claim to present the proceedings of the meeting here. On to the next! Avalon McLeod showed videos with enough of our instrument interfaces to terrify our theorist colleagues.
Black blazers are de rigueur.
Our last talk of today was Eden McEwen speaking about achieving mastery over the concept of TIME.
Also OPTICAL GAIN. And SPARKLES.
Dr. Sebastiaan Haffert closed out the session by giving us all permission to go, provided we return for free breakfast tomorrow.
This year has been a wild ride, which is to say, kind of on par with a normal pre-pandemic year. Conferences were held, telescopes were observed through, new people joined the program in real life (rather than Zoom™) and it wasn’t a big deal.
This post is not a retrospective, however. This post is to document the making of shortbread llamas, for anyone who fancies one. (Also, I owe Chef David Verdugo of Las Campanas Observatory a recipe in our exchange.)
Llamalmond Shortbread Cookies
Yield: 8-10 llamas Time: 1 hour + time to decorate Special equipment: llama cookie cutter
Received as a Christmas present
For the dough
1 stick of butter (113 g)
1/2 cup powdered sugar
1 cup all-purpose flour
3/4 cup almond flour (or almond meal)
1/2 tsp salt
For the icing
Powdered sugar
Food coloring
Cocoa (for brown icing)
Make the llamas
Set your oven to 350ºF / 325ºF convection and line a cookie sheet with parchment.
Beat together the butter and powdered sugar using a mixer on medium-high (scraping the bowl with a flexible spatula as needed) until completely combined, with a texture like creamy frosting.
Switching to low speed, add the all-purpose flour, almond flour (or meal), and salt. Mix until just combined, adding water a teaspoon at a time if needed. The dough may be crumbly, but should hold together if you press it together by hand.
Form the dough into a ball or log and wrap tightly, then pop it in the fridge for 30 minutes.
Unwrap the dough and place it on a floured work surface. Roll to 1/2″ thickness. (If it’s too hard to roll out, give it a few good whacks with your rolling pin.)
Cut out your llamas. A floured bench scraper or thin metal spatula will help you lift them off, and transfer them to the parchment-lined cookie sheet.
Bake for 15-20 minutes, rotating the pan around the halfway mark. The llamas are done when they show a slight hint of browning on their edges.
And this is what you get if you don’t rotate halfway through. Darned ovens.
Let them cool for 10 minutes before removing from the sheet, or until they’re at room temperature before decorating.
Decorate the llamas
Powdered sugar, sometimes called icing sugar, turns into icing with only the slightest encouragement. Mix your food coloring (or 1-2 tsp of cocoa powder) with 1/4–1/2 cup of powdered sugar, and dribble in water a little bit at a time, stirring until you get a decently stiff paste of the desired color.
Put the icing in piping bags if you have them, or small zip-lock bags if you don’t. Cut off the tiniest bit of the corner, and pipe a bit onto a plate to test it out.
Decorate as you wish! (The icing will be dry within an hour or so, but maybe don’t throw the llamas into a cookie jar until it is.)
Song of the Day
I apologize in advance, but this has been stuck in my head for going on two weeks now and needs to get out.
“Llama Song (Llama, llama, duck)” by some internet wag idk
MagAO-X is here on the mountain, and we have been working to unpack it since its arrival at 10am. As such, anyone looking for coherent prose in what follows is warned to expect disappointment.
We got pics tho.
This is not a pic.
Unpacking is dirty work, but it’s all worth it.
Our hands look like this:
So his hands can look like this:
Today was very “astronomy with hard hats”
But also “astronomy with cleanroom gowns”
There were occasional meetings of the two, even:
“Maggie” unpacked his new grating for VIS-X:
It was shiny:

The P.I. hugged his electronics rack once again:
MagAO-X let it all hang out:
The success of MagAO-X quite literally rests on students:
There was also a small earthquake, but it’s all good.
Song of the Day
We had 1975, now we got 1977. Ana Tijoux is a Chilean-French MC I used to listen to long before I ever visited Chile.
Trying to rap along with that is challenge mode for maintaining your Spanish-speaking skills. (I used to be able to…)
As a bonus, here’s her 2020 protest song that taught me “guanaco” is slang for the water cannon police use to disperse protests in Chile (because they both spit at you, get it?)
