Halloween 2024

November flew by, in the best way possible, I had a couple trips, spent time with family, and made a lot of progress on projects at work. It was a little jarring to discover that now, in mid-December, I hadn’t yet writtern about Halloween!

As I’ve written about before, Halloween is my favorite holiday. We decorate a bit, and do family costumes (while the kids are young enough to tolerate it, hah!). This year, our family costume theme was decided by an exchange between MJ and Aaron:

Aaron: Dada, I want to be Darth Vader.
MJ: Oh, for Halloween?
Aaron: No, I want to BE Darth Vader.
MJ: …

Well, we can’t fulfill all of Aaron’s bad guy fantasies (ahem), but we could at least let him dress up as Darth Vader for Halloween, and have the rest of us follow. Adam was Obi-Wan Kenobi, MJ was the Emperor, and I was Princess Leia.

Event-wise, the big one we did with the boys was at Adam’s elementary school, where they had various games and activities, along with a fire truck.

We also got them a pair of light sabers to go with their costumes, which they enjoyed walking around the neighborhood with before Halloween as we visited the local Halloween lights.

The day before Halloween we carved pumpkins, during which I just went with carving a single pumpkin with a very classic design. It had been a pretty busy autumn and I wasn’t feeling as creative as usual, and I had a feeling that the boys would lose interest once we got deep into pumpkin creation (they did). Thankfully, our au pair and former au pair were more creative than I.

The evening of Halloween was our biggest adventure yet! In previous years we’d only gone down our own street, but this year we added the street parallel to ours after noticing it was still early enough and the boys were bundles of energy.

Our au pair (dressed as Padme) and our former au pair (dressed as Rei) joined us for the trick-or-treating festivities.

Many thanks to the passerby who snapped our photo, I hope your kids took some extra candy!

Holiday cards 2024

Every year I send out a big batch of winter-themed holiday cards to friends, family, acquaintances, and anyone who made their way to this blog post.

Reading this? That means you!

Even if you’re outside the United States!

Even if we’ve never met!

Send me an email at lyz@princessleia.com with your postal mailing address and put “Holiday Card” in the subject so I can filter it appropriately. Please do this even if I’ve sent you a card in the past, I won’t necessarily be reusing lists from previous years. I’d like to conclude sending of cards by December 15th, so consider that your deadline :)

Note: My family is Jewish and we celebrate Hanukkah, but the cards are non-religious, with some non-religious variation of “Happy Holidays” on them.

Happy Holidays!

Lego, hardware, and a typewriter at IBM TechXchange 2024

One of the things I’ve learned in my five years at IBM is that the enterprise nature of the company means that our IBM-branded events are incredibly important to our ecosystem, and people are really excited to attend them, me included. Brand events are something I’ve definitely seen in my two decades in the tech industry, but working with an open source focus for that entire time I never really experienced it. I still prefer my open source events, but given the growth of my expertise and interest in the latest innovations from IBM Z and Quantum, the IBM-focused events offer a view into this ecosystem that’s unmatched elsewhere.

It’s also an exciting time to meet up with colleagues who I’ve only worked with remotely.

This included a bunch of community members who I’ve worked with in the open source world, or swapped fun stories with on social media over the years.

I also got to see Mainframer Barbie! Clad in her Open Mainframe Project t-shirt and an IBM Champions jacket.

But on to the technology! During one of the kickoff talks on Tuesday, Tina Tarquinio took to the stage with an IBM Telum II wafer. Wow! As you may recall, I attended Hot Chips at the end of August where the Telum II was announced, so I was really eager to get a close up look myself. As soon as Tina concluded her talk, I made a bee line for her before she had a chance to carefully pack it away. It began a running theme of the week of getting my photo with hardware.

My next dose of new hardware was getting to hold an IBM Crypto Express card, which isn’t much to look at because the cool stuff is inside, but it also demonstrates the size of one of these that gets slotted into one of the drawers in the mainframe. Definitely not what I traditionally thought of when someone says the’re adding a PCI card to a system.

A big chunk of my time at the event was doing booth duty, and I also took a few trips around the expo hall to see what was happening at other booths. I was delighted to see that the storage team had brought in a whole IBM Diamondback Tape Library! And they had it running! It was pretty cool.

A booth featuring IBM UX Research brought along a special guest that I had been clued in would be there: A red IBM Selectric typewriter.

They had attendees select from a series of prompts to them write up on the typewriter. From the printed word, they’d run it through OCR and have AI do sentiment analysis on it. It was a really eye-catching and tactile melding of old and new technology that I was totally there for.

We all know how fascinated I have been with the life-size IBM Z Lego build, and if you don’t, I wrote about it last year: All about the life-size IBM z16 LEGO® brick model! Well, IBM Quantum team decided to follow in our footsteps with their own Lego build! The latest models have a trio of components that each support their respective Quantum Processing Units (QPU), so what they did was rather clever, they had one Lego model built, and then mirrors put in to simulate three.

Even though much of my time on booth duty, I did have time to see a few sessions throughout the week. One that stood out for me was related to a Kubernetes deployment on IBM LinuxONE mainframes because of how much open source software was called out in the presentation as they walked attendees through their hybrid cloud solution. I also attended Sarah Julia Kriesch’s presentation on our Open Mainframe Project Linux Distributions Working Group. As usual, she expertly guided attendees through the value and benefits of bringing several distributions together with the shared purpose of supporting the s390x architecture.

I could say 100 more things about my experience, the conversations I had, and the people I met, but I only have limited space and time to write this. So I’ll just say that it was an excellent event and I’m really grateful I was able to participate again this year.

Open Mainframe Project at IBM TechXchange 2024

A few weeks ago I had the privilege of traveling to Las Vegas to participate in the IBM TechXchange 2024 conference. My big project there was as one of the leaders of the Open Mainframe Project event, which we’d been working on for months and took a bunch of my time (and stress!) during that time. From finding and selecting the right speakers and topics, to making sure everything worked out logistically, every detail that had an IBM component had to come through me as I worked with Mae at the Linux Foundation and Donna from Phoenix Software International.

But as the sun rose on Monday, it was time for our big day! After running around all morning to find our banners and fixing up last minute updates and changes, we kicked off the event by inviting everyone we could find who was related to the project in for a group photo.

The event itself then kicked off with a keynote from Meredith Stowell, Vice President of Ecosystem at IBM (and my VP!). She had a lot to say in the keynote about the state of open source on the mainframe overall, and where skills fit in, and new projects, including an AI-focused initiative. But what I loved most about her keynote was how eloquently she spoke on the value of open source not just to companies, but individuals and the broader open source ecosystem. This is one of those things I’ve been trying to convince people of my entire career, and to have leadership not only understand this, but be able to explain it so well, is something I really treasure.

The flagship project of the Open Mainframe Project continues to be Zowe, so we had a lot of Zowe content and were careful to make sure it was always scheduled against something that was unrelated to Zowe. As such, I ended up in most of the non-Zowe talks just because of my expertise and focus in the community. The talks were really exceptional, and I was grateful that all the talks were purely open source focused, with no hint of product or someone trying to sell something. I give credit to my peers on the planning committee for this, we thoroughly vetted speakers and asked hard questions about their materials long before the event began to make sure there were clear content expectations.

As for me, I gave a talk on the Software Discovery Tool in the afternoon, where I talked about the open source landscape on the mainframe rather broadly, and then shared where the tool comes into play. I also spoke a bit about other tools and resources that folks might want to use when learning about open source software on the platform. Slides from that presentation are available as a pdf here.

Directly after this presentation I went to the other room to participate in a panel on “Crowdsourcing Mainframe Education” where I was there to represent the mentorship program, while others talked about the COBOL Programming Course and the Mainframe Open Education project.

The sessions were extremely well-attended, and made for what I can fairly confidently say is the best in-person Open Mainframe Project event we’ve had thus far. It’s definitely going to be one of my shining accomplishments for the year.

The day concluded with sessions around 5:30 and then we did clean up before Mae, Donna, and I went to a lovely celebratory dinner. After that, I was off to my one Vegas show of the trip: Michael Jackson ONE, which was playing there at Mandalay Bay.

It was a lovely way to wind down and relax, and the show was really enjoyable. The one thing I’ll say about Cirque du Soleil shows is that they’re always beautiful and magical, no skimping on things anywhere. Perhaps obviously, you have to enjoy Michael Jackson music to enjoy it, since that’s basically the whole show, but I sure do.

Autumn activities and Sukkot

Autumn has always been my favorite season. I love pumpkin spice, the cooler weather, and Halloween. There are always a lot of festivals and fun things around, and we always find a handful of Halloween activities to go to with the kids. It’s also a busy time since we also observe the High Holy days and there’s been a lot going on at work.

After we went on the Niles Canyon Railway train two days I took off from work to spend some time with the kids while our au pair was out of town, and recover a bit from everything going on. On Monday I had the morning solo with Adam, since he had a day off from school and Aaron was at preschool. Our first activity together was putting up some Halloween lights and decorations outside. Then we went inside to make a custom t-shirt, which Adam had been asking to do for months. His subject? A BART train that we designed from a photo! On Tuesday I had Aaron for the morning while Adam was in school, and we tried out a new breakfast restaurant in town, The Breakfast Club. Everything about it was exceptional and we both ate too much.


On Saturday we had more trains! We went up to the Western Railway Museum for their Pumpkin Patch Festival about 90 minutes northeast of us. Gaby came along with us for this one, and we stopped to pick up burgers about 20 minutes from the museum, and so we enjoyed a burger picnic upon arrival, which worked out really nicely.

When we finished lunch, the boys played in the signal garden! They have a series of old railway signal crossing signs that they have hooked up to buttons that can be triggered with a press. We saw it the last time we visited the museum, but didn’t get the opportunity then to visit.

From there, it was onto the Key System tram that whisked us off to the Pumpkin Patch.

The pumpkin patch activities were supported largely by the local Rotary Club and they put on a really enjoyable time. There was a HUGE hay fort, which the boys were happy to explore on their own at first, but swiftly took my hand and made me run through with them.

There was a bouncy house! And a zipline for kids!

They also had a little hay ride that took us past a bunch of scarecrows made by local groups. On the way out we visited the pumpkins for sale, but we went with some of the smaller gourds so it was easier to bring them back on the tram, and ultimately home, with us.

It was a wonderful experience. As the afternoon wound down we got on one the last trams leaving the pumpkin patch before making the long drive home, during which both boys fell asleep.

On Sunday we finally found a way to celebrate Sukkot. The synagogue in San Francisco that we used to attend had a Sukkah in Colma that they’d set up, so we made the drive across the bay to celebrate with them. Unfortunately, the rabbi couldn’t make it and there were only a handful of people there, but we had some nice discussions and at least the boys got to see the sukkah and hear the group recite some prayers. We went from there to the city where we had lunch at Fogo de Chao, yum.


The late afternoon was spent just hanging around at home before making mini pizzas for dinner together, and then I was off to the airport! In my first work trip in months, I was off to Las Vegas for IBM TechXchange.

Niles Canyon Railway Train

On Sunday, October 13th we made our way over to Niles Canyon Railway for my birthday present: tickets on the steam train! The weather was beautiful and we arrived right on time to line up to board the train. The train leaves from Sunol and you take about a 90 minute journey south through lots of lovely scenery.


I brought a bunch of snacks for the boys, which Aaron spent much of the ride down enjoying as we sat in our seats and enjoyed the views. At the end of the line, we were able to head to the back (now front!) of the train to see them move the steam engine to the other end of the cars and reconnect.


There was also a scheduled Amtrak passenger train that traveled by while we were stopped, which everyone enjoyed.

On the journey back, we spent a bit more time away from our seats, with Aaron and I venturing back to the front of the train to take in the breeze and see the engine operating up close. Then MJ and Adam took a turn.

Once back at the depot we got pictures of the engine! And then went over to the gift shop to get a couple post cards and magnet. They have a small museum there too that had some photos and text displays. The only downside is that we had just recovered from a stomach bug the week before and caused me to be a bit more queasy than I would have liked, but I’m grateful that we didn’t have to miss the excursion entirely, as it was our last chance in 2024 to ride on it.

Science in the Park, a robot, and being organic

In early October we discovered a local annual event called Science in the Park. It was at a nearby university campus, and it sounds like it hadn’t been held in several years as a result of the pandemic so it was our first time going. We weren’t sure what to expect, but it definitely exceeded our expectations! And each of the boys left with something they’re still talking about a couple weeks later.

For Adam, it was the water robot. It mixes two things he loves, and within a couple minutes he was able to control the robot’s movement around a little water tank. With other kids waiting, we had to swiftly move on from it, but he kept asking to go back. As our visit to the event wound down we made sure to go back so he could enjoy it more.

For Aaron it was roasting a marshmallow with a parabolic mirror! He’s only 3, so he had some help, but lighting a marshmallow on fire and then enjoying the sugary result of the roasting was definitely memorable. He now routinely asks if we can light marshmallows on fire at home, hah!

They had several student robots teams throughout the event, and elementary schools that had various small activities for kids to build little STEM activities, including a sling-shot made out of popsicle sticks, rubber bands, and a plastic spoon, which we had fun with, launching ping pong balls into buckets.

The event also featured four bouncy houses that were available to the kids for free, which was a nice treat. It’s no surprse that both boys had a ton of fun with those.

Unfortunately it was a very hot day. We left shortly before noon when the temperature got up to 95 and I was beginning to wilt, later that day it soared over 100.

We had several days of unseasonably warm weather, but one of the upsides of this is that during the Sunday morning swim classes that the boys go to they often complain of it being too cold to walk to BART to take it to classes and we drive instead. But when it’s 80 degrees at 8:30AM, it’s not too cold! It’ll probably be one of the last ones of the year that we could take BART to instead of driving, so I definitely wanted to take advantage of it. Plus it’s funny to watch the boys run home from the train station in their bathrobes.

After the weekend I took Tuesday evening off to enjoy on my own. First I walked over to my favorite local sushi place for a quick dinner, then I went to visit our local one-screen theater to see “The Wild Robot” which was a really well-done movie. It was one that I was supposed to see with Adam before we all came down with a cold, so it was a little bittersweet, but I’m still glad I went, and it was a nice break for me.

Unfortunately, we’re not robots, and we got sick again this past week. Aaron got sick with a stomach bug on Tuesday night and couldn’t go to preschool on Wednesday. Adam got sent home from school with a stomach ache on Thursday, and I came down with it on Thursday evening, totally destroying my Friday and causing me to reschedule a doctor appointment. It’s probably the worst stomach bug that’s swept through the whole house.

Thankfully we were all feeling mostly better by Saturday and could ease back into the world, and gave me time to wash everything that sickness may have touched, and clean up the temporary crib mattress we put on the floor of the family room that the kids took turn sleeping on as the illness made their way through. Here’s hoping for a healthier month ahead!

Birthday and Rosh Hashanah

On September 29th I turned 43 years old. It was actually kind of a bummer, because the boys and I were dreadfully sick with a cold that included fevers. In the days around it, they missed school and everyone slept poorly. We couldn’t go out to swim class, a movie at the theater with Adam’s school, or to the fancy challah baking class Adam and I signed up for.

Thankfully, we didn’t have grand plans for my birthday, and instead I was simply welcomed with a beautifully themed cake as we celebrated with just the immediate family and our former au pair who dropped by with flowers. And no candles, because no one wants someone with a cold blowing on a cake, regardless of the infection status of everyone else.

My birthday present was quite the treat though, tickets to Niles Canyon Railway on their steam train! For two weeks in the future, which was good, because there was no way we were going out on my birthday.

On Tuesday of that week was the culmination of a TON of work: IBM Z Day. I wasn’t a track lead this year, but I put together the developer journey and consulted on several sessions, and I gave a talk in the Academic Symposium with Matt Germonprez of the CHAOSS project about the importance of open source software. I think the session went well, and thankfully I was feeling well enough for it.

On Wednesday night Rosh Hashanah began! I made honey cake with the boys, but unfortunately our bread maker broke and the new one didn’t arrive until Thursday so we couldn’t make round challah before the holiday. We participated in evening services virtually after the boys went to bed, and the next morning I took the boys out to the park to run around for a bit before morning services at 10:30AM, which we also joined virtually. The bread maker also arrived, and while strictly not appropriate to bake challah on Rosh Hashanah, we did anyway. A round challah! Which came out pretty decently. Plus, being able to bake the round challah together helped get over some of the disappointment of missing the fancy challah baking event the weekend before.

In the late afternoon, we cut up a bunch of fruit and figured out how to extract the seeds from a pomegranate to enjoy some fruit and honey.

Happy New Year! We’d like to finally attend services in-person again next year, but things just didn’t come together for it this year, especially with everyone being so sick in the days leading up to it.

If I’m honest, it was a lot for one week. I really wish we hadn’t gotten sick, but with little ones in school it’s tricky to avoid it, as we’d also discover two weeks later when we all got sick again. Oof!

MUNI Heritage Weekend 2024

Last year we missed MUNI Heritage Weekend due to the whole house being taken down by a COVID-19 infection, so with everyone feeling well this year, we made sure to make our return to the festival I love! This year marks the first time MJ and Aaron have attended, with me having gone a bunch of times, and Adam in 2019 and 2022. It was nice to have all of us there to enjoy it.

The day began with checking out a couple buses, and then getting in line for the Blackpool “boat” tram. The boys and I went on this one ourselves as MJ had to run off for an errand nearby. Aaron also had his Studio Ghibli Catbus with us all day, while I had my MUNI Catbus t-shirt, so we made quite the pair throughout the day.

It’s number 233, and painted with green livery (as opposed to the red) and came to San Francisco in 2013. I’m glad we managed to get on this one, as it’s the one that the boys have a poster of hanging in their room and have never been on before. In preparation for the day, I listened to the Ahoy! episode of MUNI’s “Taken with Transportation” podcast to get a refresher on these trams, and it made the adventure that much more fun as we sailed past Ferry Building on our journey down the Embarcadero.

At Fisherman’s Wharf we got off and got some great pictures while the operators took a break. To get back to Ferry Building we took one of the regular service F-Line vintage streetcars to mix things up a bit. Plus, it got us back faster, which was important because the boys were hungry. We met back up with MJ and had lunch at a nearby hamburger joint.

From there it was time to visit some vintage buses! I think the boys like buses more than trains, so this was probably their favorite part. We started off with a ride on the MUNI AM General 4154 from 1975. It took a loop through SOMA, making its only stop at the Caltrain Depot, which was a very specific stop for the day because Caltrain was also having a celebration: for full electrification of their San Francisco to San Jose route. As you’d expect, there was overlap in folks enjoying festivities for both transit agencies. Once that loop was done, we visited the booths in the plaza for a little bit to geek out with fellow transit fans.

Our final ride of the day was upon Adam’s request, the 2230 Mack Diesel Coach from 1956, with the very distinctive Pepsi bottle cap decoration on front. All the buses take the same loop, so the scenery was the same, but we all enjoyed it just the same.


Our final stop was the museum and gift shop, where Adam bought a boat tram post card with some coins from his wallet (and a little help from my Member discount). In all, a very satisfying day! And I was so happy to share it with the whole family.

After work with the kiddos (and without)

I talk a lot about our big weekend adventures, but what do people get up to with their pre-school and elementary kiddos on weekday evenings?

Activities with kids is one of those topics that I wasn’t prepared for at all as a parent. I quickly discovered that my own after-work hobbies are largely incompatible with small kids. There’s also the unexpected mental load of managing what we’ll do every evening, because if I ask them, they’ll likely reply with some grand adventure and a desire for cheeseburgers. So, every day, I think things to do and evaluate my energy level to make sure the options won’t cause additional stress. Once I have my list, I can give the kids something to choose when I take over from our au pair at 4PM.

This may seem like I’m giving myself too much work by being so prescriptive about this (“just let them play!” “when I was a kid I didn’t come home until sunset!”), so I’ll start out by saying “just play!” is definitely something that lands on my list. But overall if we don’t have plans to choose from it’s a whole night of me telling them “no” to whatever complicated thing they want to do, which is dreadful for everyone. And they’re only 3 and 5 years old, things will loosen up as they get older. Besides, it’s great bonding time, I am grateful for the ability to have so much time with them and if we can go on grand adventures in the evening, we will!

Loosely, this is our evening schedule:

  • 4 – 5:30PM: Activities
  • 5:30 – 6:30PM: Make and eat dinner
  • 6:30 – 7:15PM: Wind down activities, no screens (too close to bedtime)
  • 7:15 – 8PM: Bedtime routine

Here’s what I’ve come up with:

  • Just play! They have lots of toys and free play is so important to development that they use their imagination
  • Play outside: bikes, drawing with chalk, bubbles, toys
  • Outdoor picnic: we even bought little baskets and checkered paper to make it a whole event
  • Baking: banana bread! muffins! cupcakes!
  • Make mini-pizzas for dinner
  • “Pizza party” with a movie downstairs and pizza we order
  • Art: either a project I’ve put together, or their ideas
  • Play-doh or Kinetic Sand
  • Lego construction
  • Homework: it’s optional in Kindergarten, so it only really comes up when they’re in the mood
  • Puzzles
  • Board games
  • Chores: they sometimes like helping with dishes, or laundry, or taking out the trash, and I have to do this anyway…
  • House organization: they love seeing all the junk I can pull out of our closets and discovering new treasures
  • Limited computer tinkering: I have to be very careful, but Adam sat by while I replaced a failed harddrive in my desktop recently
  • Holiday decorating: Outside hanging lights, putting decorations in windows and around the house
  • Errands: Grocery store, bank, Target runs (via BART)
  • Dinner at the mall (via BART)
  • Go out to a playground
  • Gardening: water plants, weed lawn, plant new plants/seeds
  • Kitchen science experiments: So much baking soda
  • Lots of TV (good for when I’m sick, tired, or just can’t even, hah!)

This massive list was an evolution that started with nothing. There were several Google searches around things to do with kids, and then we had to tailor it to what our kids actually like. But we never spent much time around kids before having our own, so it’s all been a learning experience. Plus, these are pandemic kids, we couldn’t leave the house for two and a half years and had to get creative. No play groups, no library activities, nothing that I would have normally hooked into to keep the kids engaged with the world.

To help sort through this and make the kids less anxious about “what are we going to do?” we have a physical visual schedule that they can operate themselves by picking out pictures from the options I provide. We implemented the visual schedule over the summer to help bring some structure to their days so they knew what to expect, but it works brilliantly for evenings and weekends now that they’re back in school.

Still, as much as I value this time together and these activities, I miss my old hobbies and I’m an introvert who needs recharging time. A while back we decided to get a babysitter once a week so I could spend the evening on whatever I want, without parenting responsibilities. Unfortunately, we got busy, things came up, and I didn’t make an effort to prioritize these nights, and so they didn’t happen. I think I was getting a little burnt out over the summer after some rounds of sickness through the house and some extra things on my domestic plate. Lyz nights had to make a return! And this time, with a priority flag. I started taking them in early September.

I spent my first Tuesday just relaxing in the back yard in the hammock and some TV on my tablet. Another evening on my own I went out to the local one-screen theater in town and saw Beetlejuice 2 and then went out for sushi at our favorite local place.


Our local library is open until 8PM on Tuesdays, so that’s a nice place to spend time at if I’m just looking for a quiet place away from home to read for a little bit, which I often am. Last night I spent playing a Wallace and Gromit game on my Meta Quest 2, which I hadn’t touched in months! It needed updates and the controllers needed new batteries, hah. I then watched a little TV and picked up some pizza from The Slice House, which recently opened in town.

I expect to do some grander adventures in the future outside of town and with friends, but again, we’ve all been reeling from a series of colds and I’m putting a higher value on rest right now. Most importantly, having this time to myself allows me to look forward to tackling projects or just taking a break from the weight of responsibility that parenthood has brought. And this break allows me to recharge a little bit more, and be my best self for my family.
