But over the summer we picked up some fun light up FasTrack that we thought would be fun around the holidays, and I mentioned over Thanksgiving we got it set up. Now that I’ve had some time to sit down and take pictures I’d like to document what we came up with a bit better.

Starting point: Circa 2000 train set and transformer with classic Tubular Track, including the Lionel CTC Lockon.

Where we wanted to get to: Use our fancy new Lighted FasTrack!

The first, obvious, challenge was that my transformer didn’t connect to the track with a plug, it uses the CTC Lockon. How do I get power to this fancy track that has a plug hole? Fortunately, I explained my setup so when the local train shop sold us the Lighted FasTrack, they also sold us a FasTrack Accessory Power Wire (6-12053) which we’d need. Except that I didn’t have any idea how to use it. As I mentioned in my last post, this post on Reddit included enough photos for doing the same with some standard track.

But if you’re looking for something more direct and clear, here’s the photo of what I did:

As you can see, there’s a wire that extends from the plug, and I’ve unplugged that. In its place, I’ve attached my new FasTrack Accessory Power Wire. And that’s it! Time to find all those tiny screws and close it back up.

From there it was a matter of attaching the other end of my new accessory power wire to my transformer. The wires are exposed, so you can test them by touching them together, but you should secure them in some way. That’s when I grabbed my husband for some help because I knew he had a collection of wire couplers that could come in handy for this project. He attached some detachable couplers that could be used with either track type.

Now I just need to address the squeaky wheels.

The day after we got home, I grabbed tickets to Oakland Zoo Glowfari. The tickets for weekends tend to sell out quickly, and it’s busy, so I decided that we wouldn’t wait and would just grab a weeknight far enough before the December holidays that it wouldn’t be too crowded. So the boys and I went with Gaby, our new au pair Ana, and then their former au pair Rebeca joined us! It was a ton of fun, the structures are beautiful and there are a lot of them. The first area we explored was a future of Oakland-themed village which had all kinds of great Oakland landmarks, including the Tribune tower, the boot from Children’s Fairyland, and a Chabot Space & Science Center observatory.

Plus, they had a BART train you could go inside! And run inside, which the boys did, of course.

From there we walked through areas devoted to insects and African animals. Of particular interest to every kid there was a tile you could jump on to trigger a stink bug to spray “smoke” out of his rear end. Oh boy.

We then met up with Rebeca and got a bunch of great photos of the boys and three generations of au pairs. I’m really glad we were able to do that before Gaby went home! With Rebeca, we took the Gondola up to the California Trail to explore the ocean part of the Glowfari. Up there the bubbles filled with “smoke” were a big hit with the kids. They were pretty cool. We didn’t get to go on the Zoo train which gets you to even more light up goodies, but since just train tickets are required for that, I’m hoping that we can go with MJ some time in January to just do that.

I mentioned Gaby leaving, and that was a pretty big deal for all of us. She’s our first au pair to actually go home at the conclusion of her term (the first got married, the second stayed to go to school in the US). As a result, the boys still see their past au pairs! We’re really going to miss her. I think we got really lucky with our new au pair though, the boys immediately connected with her and she’s been great so far.

The following weekend we joined a bunch of other Bay Area Rapid Transit (BART) fans at Rockridge station for Sweaterfest. It was a whole little celebration with BART crafts and other related pop-ups with little activities for kids and photo opportunities. At the end, they took a big group photo with us in our sweaters! MJ wore one from when we attended a couple years ago, Adam and I had matching BART sweaters from this year, and Aaron donned this season’s BART winter hat (no shirts in his size this year). We got to ride the BARTmobile (a hilarious train with tires that use used in parades and other events), and managed to get in the group photo.

Inside the BARTmobile!

We checked out the craft table briefly and the boys got to jump around inside a big inflatable winter bubble. It would have been nice to arrive earlier since things closed fairly promptly around 3PM, but we still had fun, and it was probably for the best that we didn’t go on such a long adventure, did I mention December was very busy?

The next day, we went to the Great Train Show, which was set up at the Alameda County Fairgrounds. This is also an event we’d gone to before, I think it was last summer? Last time, MJ realized he knows one of the folks who regularly attends with one of the model train clubs, as they used to work together, so he likes to use it as an opportunity to say hello.

Plus, it’s a great place to shop for model trains to expand our Hanukkah train layout! Sadly, the engine on ours wasn’t working well. In spite of buying it just five years ago and only taking it out for the winter holidays, think it was dropped a few too many times by small kids. We brought it to the train show to test it on their test track, and that’s where it completely failed. We tried to get a replacement engine, which is lovely! But will take some work to get it going with our equipment. Still, the fellow who sold us the engine also had a really cute Hanukkah box car that we bought along with it. And maybe I’ll see if I can get our other engine repaired.

The boys also got to check out a couple of retired maintenance cars that are kept running by members of the West Coast Railroaders Group. Some people have boats and sail over water. Some people buy old rail maintenance cars and ride down tracks through beautiful forests. MJ spent some time talking with them as the boys kept themselves occupied by sitting in the cars and playing with the controls.

It was a fun afternoon, but I was tired. I had developed a sinus infection that was being treated with antibiotics, but I think what I needed was rest, and not a weekend full of train adventures,. I was also prepping everything for Hanukkah, which had me up on a ladder outside hanging Hanukkah lights during this time too, something I thought I’d skip this year but ultimately wanted to do because I love holiday lights. And prepping to come back to Philadelphia. It’s no wonder I was feeling worn out.

We’re in Philadelphia now, and while I didn’t take much time off of work through the winter holidays, I am grateful to be able to focus on more project work that tends to bring me more peace and calm. I’ll try not to overdo it activity-wise while we’re here. I think I’m finally over the sinus infection, but both my body and mind could use some time to relax and recharge. Maybe some time reading a book by the fire. We’ll see how that goes.

We also picked up some cake at the airport that he could enjoy on the flight. When we boarded, wearing his new birthday t-shirt, he also got to enjoy a quick little tour of the cockpit. Plus, the change in time zone means he had a 27 hour birthday. Not bad!

His actual birthday party was held on Sunday when we were all back home. Guest-wise, our previous au pairs, Rebeca and Gaby, joined us and our new au pair Ana. As requested, it was Paw Patrol themed!

It was a fun afternoon. Maybe next year we’ll extend the birthday to some kids Aaron’s age, but pandemic habits die hard, and it’s been a pretty busy season for all of us.

Aaron has been enjoying his new-found access to video games. He’s starting out with a Paw Patrol game and Mario Kart, but I expect he’ll quickly graduate to some more complicated ones. I’m super proud of how much he’s matured in this past year. He’s doing great in Transitional Kindergarten at the public school, and he surprises me all the time with what he’s learning and understanding about the world.

So first, thanks to Beth Lynn, Vance Kochenderfer, Susan Rose Dudenhoefer, and the other volunteers who brought the event together this year on a tight deadline. I’m so grateful I thought to include the conference on my quarterly event requests in spite of it not being announced yet!

I’ll also mention that I keep calling it “Ohio LinuxFest” but they rebranded as “OLF Conference” to reflect “Open Libre Free” and their goal to include operating systems beyond Linux, mea culpa!

The event itself was a lot of fun. It was smaller than in years past, as they went with one track. They mentioned at closing that doing it in December is too late in the year, and along with the short runway for the conference likely impacted attendance. Still, if I had to guess I’d say there were a couple hundred people there.

I saw a lot of familiar faces. My friend Scott came out from Pittsburgh, and though we still chat regularly in a group cobbled together from our Ubuntu Pennsylvania days, we hadn’t seen each other in person in years. It was really cool to catch up, and to laugh about kid stories, since we’ve both became parents since we last saw each other. I also got to spend a bunch of time with Amber Graner, who I also got to know very well during our time in the Ubuntu project. We’ve stayed in touch, so we’re still pretty close, but this was the first time in a while that we had more than 20 minutes to catch up. And new people! I got to chat with a student who was attending an open source conference for his first time, and met several folks who have been working in open source for decades. It really was a great mix of folks.

I really enjoyed the opening keynote from Don Vosburg on Passion and Pragmatism. He tugged on a familiar thread in the open source world around the fact that a lot of folks got into open source software “for fun” or the passion of it, but most of us eventually had to get professional jobs that may have tested our fundamental commitment to open source. Or other things that have arisen in our lives that require us to make a choice. I’ve definitely had to walk a line throughout my career, but consider myself quite lucky to have found myself a series of good positions that have allowed me to follow my passion and make a living.

My talk was just after the keynote, and I was very happy that most people stayed! It’s a re-working of a talk I gave last year, but I notably added an architecture and made some adjustments to my slides about software testing. I was amused to learn that my closing keynote back in 2018 was about doing software testing on your open source project, and that this could be seen as an expansion of that. I joked at the beginning that I was very glad everyone listened to me last time, and now that they all have software testing, it was time to add non-x86_64 hardware architectures into that testing matrix. The slides are available here: Will_your_open_source_project_run_on_a_mainframe_Or_a_watch_OLF_2025.pdf (1.2M)

Thanks to Scott for taking a picture during my talk!

Catherine Devlin’s “Graph Data for Heroes II: Rise of the Bot” was an interesting one. A large chunk of it had her scraping web data, and as I was live-posting about it on Mastodon and Bluesky I was speculating about how web scraping is one tech that hasn’t gotten a whole lot better in 25 years, then mused that it was actually a good use for AI/ML technologies. Indeed, that’s where her talk went!

Scattered throughout the conference foyer were a few tables from supporters and sponsors, and I was delighted to see a series of ChromeBooks that had been repurposed to use various Linux distributions. I was delighted to see that Xubuntu made the cut, and when I walked over to check it out I was presented with our shiny new website. Lovely!

In the afternoon I enjoyed seeing Steven Pritchard’s “The Great Open Source Rug-Pull” where he talked about open source software license changes, which have caused a lot of disruption and contention in the open source world these past few years. And although I had heard of Hacker Public Radio before, it wasn’t until murph’s talk on the topic, along with a bunch of great tips, that I got a serious look into what it was and how the episodes are crowd sourced. These folks are doing great work.

Amber Graner concluded the day with the closing keynote “Bless Their Hearts: Open Source, AI, and Southern Survival Skills.” She took us on a personal, funny journey through some of the characters and situations in the open source world. I particularly loved at the end where she shared a list of things she wished people had told her when she started contributing to open source. I’ll be keeping some of these things in mind as I continue working with students who need more than just the basic misconceptions about contributing corrected so they can effectively contribute.

The end of the event crept up quickly! The group hosted a small closing after party in the hotel lobby with pizza and my favorite, cake!

In what is perhaps one of my shortest conference trips, I flew out at 5AM the next morning to get home by midday on Sunday. It left me pretty tired, but it was worth it.

We arrived on Saturday night and were able to meet with my father in law for lunch the next day. MJ and I worked Monday through Wednesday while our new au pair settled in with the boys and started exploring the area with them (library! trampoline park!). As we prepared for the holidays, the boys and I set up the Hanukkah train (a vintage Lionel train) and put away the LEGO train we usually have out. When we were in town over the summer, we had stopped by Joe’s Train Station, our local train hobby shop, and picked up the Lionel Lighted FasTrack that we opened to use for the first time. Since our train is older, it didn’t come with modern FasTrack, and has a clip that went on the metal tracks, that also meant it didn’t have the standard power cable that’s often used. When I bought these lighted tracks, they also sold me the FasTrack Accessory Power Wire (6-12053) and I was left to figure it out myself. Thankfully, the model train community is very active! And eventually I found this post on Reddit helped me get the wires from my transformer connected the way they needed to be. I wish I had taken a better picture before I put the bottom plate back on, but it’s transparent so you can kind of see where I disconnected the power from where a plug would generally go, and replaced it with my wire. And then, voila! It works!

Well, it worked with some wires exposed and Adam was scared of being zapped (fair) so MJ put some connectors on the ends of the wires so we could not only more easily use the lighted track, but also switch back to the metal track easily. No more fiddly connections at all!

The light follows the train, now I just need to convince the boys not to put so many cars on the track at once.

Speaking of building things, the drawer on my desk has been unstable for a while, and finally broke entirely over the summer. I’ve been living out of some bins next to my desk, not optimal! MJ bought the wood and brackets needed to fix it, and the boys helped them with the repair this trip. Woohoo! A working drawer once again!

The boys have also been building a lot of Lego. I always thought that the skill levels for Lego sets were based solely on the complexity of the components involved, but we picked up a Bluey House set recently and there’s more to it. On the Bluey set the pieces are simple, but the instructions are also much more detailed and even show hands holding a specific piece and exactly where that single piece goes. I was helping Aaron (almost 5) build the house at first, but after a while he said he wanted to do it himself, and he did! So proud! Now he’s got the bug and wants to do a lot more.

On Thanksgiving we woke up and made Death Star waffles! And then I spent a big chunk of time in the afternoon making food for the potluck dinner we had at my sister-in-law’s house. I’m not much of a cook, but I could manage carrots, green beans, and stuffing, and everyone was quite happy with vegetarian brown gravy from a jar and cranberry sauce from a can. The dinner came together beautifully at her place and our usual chaotic family Thanksgiving was fun.

Being over there reminded Adam that she had a fire pit, so that’s how we ended up with an outdoor fire, in Philadelphia, in November. It was COLD! But I’m glad they got it going for him, they kids really enjoyed it.

As our visit wound down, we spent an evening at Astra Lumina, a nighttime walk through various light features in a forest in Jenkintown. We went with the parking option that used the shuttle, which we figured would be more fun for the boys anyway (yep!) and was a lot cheaper. The frequency of the shuttles made it quite a reasonable option. From there, we got to explore the lights! The boys love being outside and playing with lights in the dark, so it was a perfect mix of things they enjoy. It’s on the pricey side, but for us it was all worth it. Afterwards we had a great dinner at Vintage, a restaurant MJ’s grandfather was a fan of, and I had a spectacular seafood dish while Aaron fell asleep on the bench.

Following the weekend, it was back to work on Monday and then we packed up on Tuesday to fly home. If not for the kids going to school, we probably would have stayed through the winter holidays. Our next trip back east was just 15 days away.

That week my Aunt Mary Ellen and Uncle Joe were drifting through town following a conference in Napa and we made plans to meet up. The boys were excited by the prospect of a ride up to San Francisco, but then some plans shifted and it was rainy. We made the best of it though, instead of meeting up early for dinner, the boys and I took BART, MUNI
Metro, and then hopped on a Caltrain for a few stops before taking BART back downtown to meet for dinner. It was a lot of trains for what amounted to a big loop, but the boys have been asking to go on Caltrain for quite some time, and I figured this was the perfect opportunity. It was also a nice opportunity for us to pause and have some snacks since Caltrain is the one local train that they can eat on!

After the trains, I took the boys up to the roof deck at the condo (between tenants right now) to take in the gorgeous sights of downtown San Francisco at night. Adam actually gasped at the sight when we got up there. It really is beautiful.

We met MJ in the city and met my aunt and uncle for dinner at Fogo de Chao for a lovely dinner. It was really nice to see them, it was our fourth attempt to see them in the span of 18 months, which every other plan being ruined by illness (COVID, flu). We had a nice time finally catching up, and it was the first time that Joe was able to meet the boys, and the first time Mary Ellen met Adam. They boys did great, actually engaging in conversation rather than instantly demanding their phones for TV, which was nice. We definitely kept them up too late though, Aaron fell asleep on his chair toward the end, and they both zonked out in the car on the drive home. Carrying Aaron out of the restaurant, I completely forgot to get a family photo! Whoops. Next time.

The first week of November concluded by celebrating Gaby’s last birthday with us. I finally succeeded in making brigadeiro! With her help. And we picked up a custom cake that I had ordered the week before. Adam decorated, which is how we ended up with jungle animals on the tablecloth, hah!

We then had a rather chill Saturday that concluded by attending the Castro Valley Light Parade. It’s funny, we’ve lived in Castro Valley since 2018, but this is the first time I actually managed to see the parade! I was either working or traveling, and one year life with little kids meant we simply made it out of the house too late to see the parade. But I finally saw it!

Aaron got a light-up balloon that he swiftly asked me to hold (I’m glad we only got one!) and after about 45 minutes of parade the boys had enough and we walked out to our favorite restaurant just down the Boulevard. It was enough to get a nice taste of the parade though, and we really love enjoying events in town with the rest of our neighbors.

MJ flew out for a work trip later that night, so the boys and I had Sunday to ourselves as we did swim class, haircuts, and a trip to one of their favorite playgrounds. That evening, Aaron and I made banana bread for his monthly school project where he also got to draw the ingredients and take pictures. For a quiet weekend, it was surprisingly tiring!

We spent the week with normal life stuff, lots of school and work and random things like appointments, including a follow-up to check on Aaron’s infection (getting better!). The next day, he fell off his bike and landed on his face, earning him another visit to the urgent care. Thankfully, he was OK, having narrowly escaped getting stitches on his lip. Yeesh. Kids.

The next morning we were up bright and early for a Saturday morning garage sale! The boys and I go to a lot of garage sales, and Adam has been talking about his desire to have one of our own for over a year, but we’d never done one ourselves. We didn’t take the request very seriously because sitting in our yard for hours for a few bucks doesn’t sound like fun, but with Gaby heading back to Brazil soon she was looking to sell a bunch of things so she could have a lighter collection of things to bring home. Well, if Gaby wanted to do a garage sale, we might as well toss some of our things in too!

I don’t think I thought it through completely. Garage sales are actually quite a bit of work, from developing the listing online and putting signs around the neighborhood, to figuring out what we’ll get rid of. Then actually setting up, and then cleaning up when we were done! It was nice to get rid of a bunch of stuff, and the $100 we got for it was nice, but it wasn’t nearly enough to make me want to do it again any time soon. Next time we’re going to just make some donations, maybe sell the higher value things on a local Marketplace board or something. Don’t tell Adam, he’s already making plans for our next one.

That evening, we picked up our new au pair from the airport! She had a week of overlap with Gaby so she could settle in and get shown the kiddo care routines. I was grateful for all of this, since both MJ and I have been slammed with work lately, and it would have been a real challenge for either of us take off time from work right now.

The weekend wound down with a visit to our local Lego reseller shop where we all had some fun digging through Lego bins for a couple projects we have in the works (including one related to work which led to: “We have to go to the Lego store.” “Have to?” “It’s for work!” “I doubt it.” hah!). We also started prepping for our Thanksgiving trip to Philly and generally trying to get things in order for the winter holidays.

Mix in with all this, I’ve also been doing a lot more cat care than I expected. I haven’t written about it much here, but it turns out our beloved Zara came to us with a paw and tail wound that have been taking forever to heal. Her paw seems better now, but the tail wound became infected with MRSA and is proving to be a lot more stubborn. We’ve tried a whole slew of treatments which I’ll write about at some point, but it’s been a lot.

Still, she’s an absolute sweetheart who continues to love her wild human brothers, so she is still the right cat for us. Thankfully, as Gaby enjoys some vacation time before returning home, she agreed to watch Zara and take care of her, even taking her to a specialist vet visit that was really tricky the schedule. I hope she starts to heal up soon, but at least she’s in good hands while we’re in Philly this week.

To celebrate, I wanted to bring our success story and opportunity for projects to GitHub Universe this year. I was lucky that it was taking place in San Francisco, so there were no travel costs for me, and doubly lucky that the IBM team sponsoring the booth was willing to have me join them. It was a great experience working with the organizers and my fellow booth staff, we had representation from various parts of IBM so it was easy to direct attendees to someone helpful based on what they were interested in. For my part, I wish I had brought along a bigger sign saying something like “I give free stuff to OSS projects!” so the hobbyist contributors weren’t scared off by the more enterprise nature of IBM. Maybe next time. I was able to have some great conversations though, and could show off the work we’re doing with a screencast of the on-boarding process that I prepared on my tablet.

And I wasn’t the only mainframer there! Folks from Broadcom had a booth where they were showing off their Code4Z products that integrate into a standard VS Code environment.

It was a great event for me to be at to show off mainframe goodies to a distributed tech world that’s less accustomed to them. I was even able to clue in a few IBMers to the business we’re doing over in IBM Z land.

Personally, it was a wonderful event to be at to catch up with folks I haven’t seen in a while from across my tenure in open source.

I think my two biggest takeaways from the conference were 1. Wow, AI. and 2. How different conferences are when the talks aren’t necessarily the centerpiece.

Most of us in tech have a very different immediate relationship with AI than people in the general public. For us it’s less about results from ChatGPT and AI-created images, and more about what AI that knows how can code will do to transform the tech industry and what’s possible. We all knew that basic Python coding tasks would start to be replaced by AI, but we’re actually seeing that in practice now. No longer just autocomplete, we can vibe code a whole application.

One of the keynotes showed the presenter finding an old Bluetooth-enabled Furby in a closet and using an AI coding assistant to update an old open source software library so he could use it in 2025. The story here was that as a silly fun thing, he probably wouldn’t have ever had time to tinker with it, but now it’s easy. I’m not saying anything new here, and I do understand the difference between vibe coding a Furby and writing a production application, but in the near term it clearly will make some of the more mundane tasks easier to pass off to AI. I really would like one to automatically keep up on Node.js dependencies for me, it’s the most dreadfully tedious task.

All of this is to say that at the conferences I attended this year, I saw a real maturity turning point in the AIs-that-can-code realm. And GitHub is a big player here because of how integrated their code tooling already is in so many organizations, and throughout open source software communities.

Phew.

As for my second point, the talks not being the centerpiece. I’d say there’s still the spine of what holds the conference together, but there were fascinating experiences scattered throughout the event, both from vendors and from GitHub. The vendor booths was woven throughout all the buildings, and there was often a seamless transition between GitHub activities and vendors. One moment you’re designing your own Octocat sticker, and the next you’re getting a coffee while chatting at the IBM booth.

I enjoyed the building activities, our options were a GitHub light or a GitHub Copilot Lego model, and I went for the Lego. It was a nice little relaxing break from conference chaos.

The venue of Fort Mason was also lovely, and they had regular shuttles from downtown San Francisco which made the hurdle of transportation a more surmountable one. Both mornings I had an easy journey on BART to a shuttle that left from Embarcadero station. Once there, the gorgeous San Francisco weather we enjoyed offered the perfect backdrop. If I needed some air, I could walk down a pier and get a glimpse of the Golden Gate Bridge. They also cleverly placed a giant GitHub sign so that you could see beautiful Alcatraz Island through it.

They served good food and we had lots of places to sit and enjoy it. And after one tour through the main keynote building where I played a game to get a juice, I had no problem finding a shady spot to sit down and do a half hour of urgent work that I had to knock out.

The electronic badges were also a lot of fun. You had the option of getting one during registration, and they were little devices powered by an ARM SBC. As “hackable” badges you could play with them as-is, but also make some changes to the code included on them to do things like show your GitHub stats and they had a whole area with laptops that would allow you to do this (good thing, I can’t plug anything USB into my work laptop!). Once mounted on your device, they have a whole website of activities and other tools you can add to them. Cool. The scavenger hunt was also fun. I found they held a charge for about 10 hours, depending on use, so while I charged my overnight and took it off the charger at 7AM to head to the city, it barely made it to 5PM. I brought my digital badge home and it’s sitting here by my desk, maybe I’ll vibe code some new stuff for it, haha!

I’m certain that having such a fun and engaging space is all designed for encouraging brand loyalty. People have a great experience at these events in addition to learning things. I have always had mixed feelings about GitHub, and I still do, but some of the high points are definitely around usability, in spite of being built around Git, a tool that’s notoriously difficult to use! And usability includes feeling comfortable, which GitHub Universe did beautifully this year.

One evening after school we went over to the pumpkin patch and handful of carnival rides that we can see from the highway. It’s expensive for what it is, with the rides all being pretty quick and forgettable, but I kept our activities within some clear parameters as we all had a good time, even if I still hate bumper cars.

A week before Halloween was the Halloween carnival at the elementary school. This is always a fun one for the boys, and it was the first year that it was Aaron’s school too! As usual, they had lots of little activities set up around the schoolyard to play and win prizes at. I really enjoyed the photographer who got a great picture of the boys and I (rare, since I’m usually holding the camera!) and I’m grateful that the pumpkins the boys picked out from the little pumpkin patch there weren’t too big for the walk back to the car.

Over the weekend we met up with my friend James at Hiller Aviation Museum. With MJ traveling throughout a chunk of October, it was nice to have another adult join me on a Halloween-themed adventure! In this case, it was a pumpkin drop from a helicopter, because, why not?

They had kids sign their name on the pumpkin that would be dropped, which was fun until Aaron realized the pumpkin would be completely smashed upon landing, along with his name. Oops.

They had Halloween-themed games and crafts set up throughout the space, and then a “Haunted Hanger” with a TON of spooky decorations throughout their exhibit space. We enjoyed making our way through the exhibits before the pumpkin drop, but we wasted no time getting outside in time to see the pumpkin get loaded into the helicopter and take off.

They had everyone stand behind a temporary fence and look away as little rocks and dust were kicked up during take-off, and then we all got to go over to the runway fence to see the helicopter actually drop the pumpkin. It did a couple loops before the drop and I have to admit, the actual drop was a little anticlimactic. We were close, but a pumpkin compared to a runway is quite small! Still, it was an amusing activity, and if nothing else the boys LOVED being so close to a running helicopter. Me too.

See that little dot? That’s the pumpkin.

The next day the boys and I glimpsed outside to see some gloom and potential rain, but there was another Halloween activity to get to! The park next to the school the boys go to was hosting a Halloween Make-a-thon where kids got to go to various tables to do crafts. It’s the first year they did it, and all of the volunteers seemed pretty overwhelmed with the constant flow of kids clamoring to do the crafts – even with the threatening weather! I suspect they need a bit more organization and volunteers next year, but I see a lot of potential.

As the event wound down, we went to the indoor space where I enjoyed making Halloween-themed magic wands more than anyone else, but Adam got to finish his scavenger hunt, which was quite satisfying for him. When we went to leave, the rain had finally showed up, so we waited a few minutes for it to calm down before our soggy walk back to the car, but thankfully we didn’t get too wet.

The final activity before Halloween was pumpkin carving. After work on Thursday, the day before Halloween, was the time we chose for it because of how quickly the pumpkins grow mold here, even when outside in the shade. We had someone over who has been helping with the boys, and she was delighted to help Adam carve his giant pumpkin into a cat, and Aaron and I got to work on the bat design he picked.

The both came out beautifully, but I’m glad I didn’t give in to their request to carve any more, because as expected, the adults did the vast majority of the work. Still, we had fun and the boys were enthusiastic throughout the whole process.

And then it was Halloween! MJ was home for Halloween and donned a Zoo Keeper costume, since he’d be herding around a cat and a bat all evening as we trick-or-treated. I went with a witch costume, and joked we were going with the classics this year. Our old au pair and current au pair joined us for the evening as well, which was really nice. We stay always stay in our neighborhood for Halloween, which gives us an opportunity to see and meet neighbors.

We also have several neighbors who go all out with Halloween decorations and activities, some of which are scarier than others. And enough of our neighbors in general participate in the holiday so the walking:candy ratio is perfect for us.

The boys got to bed much later than expected as they raided their candy bowls, enjoyed handing out candy to other kids who came later, and generally got to enjoy spending time with Gaby and Rebeca. It was a great night.

But first, we decorated! I’ve been putting up Halloween lights for the past few years, and the boys have enjoyed putting up their own decorations that they buy at the dollar store or Target. Adam asked for a smoke machine and a lot more elaborate decorations, but he’s still only six years old and if carving pumpkins is any indication, I’d be the one doing all the work 10 minutes after he got bored with it, hah! Maybe in a few years.

The first Saturday was spent at Joan’s Farm and Pumpkin Patch in Livermore, which we arrived at just after they opened at 10AM. I’d been searching for an autumn activity with the boys that had the right mix of activities that we’d all be happy, but also wouldn’t be overly expensive. This place checked all the boxes. It was a little bit of a drive out to Livermore, but I got wristbands for the boys so they had unlimited activities, from a giant bouncy slide to pumpkin bowling, a corn maze, and hayrides.

They got to visit with animals on the farm, and pick out pumpkins, with Adam naturally picking one of the largest he could find. We even managed to get lunch there, which both the boys actually ate, before running off to activities again.

Back in town, we grabbed dinner at one of our favorite local restaurants before heading off to our evening activity: A dinosaur-themed unhaunted house at a local nature center! Parking was a bit of a nightmare and I don’t think we scheduled enough time to enjoy the Halloween carnival, but these are good things to know for next year. The unhaunted house was fun, with Aaron getting to pet some animals and all of us learning a bit about dinosaurs and their descendants.

The carnival portion was pretty cute, with various little stands set up where the boys could play games and then their favorite activity, jumping around in a big inflatable bubble with balloons floating all around.

We spent the next day closer to home. After morning swim class, the boys helped me replace the artificial grass in the back yard that we have covering a section of tile (mostly broken) and slab concrete we have out back. It’s not the solution I want for the back yard, it feels quite wasteful to change out the fake grass every few years, but until we can plan for a nicer back yard, this is a good middle ground to making it usable.

Adam also helped me rearrange the furniture and play things out there, which has all been a nice change. What was not a nice change was discovering wasps in our big umbrella out there, but fortunately the cooler weather seems to be dispensing with them naturally.

For my part, I repeated the IBM LinuxONE AI Arcade that we did at the Red Hat Summit back in the spring, with a few adjustments. Our footprint was smaller (2 laptops instead of 4) and I made some tweaks. The biggest change was that during the sandbox (expo) opening Block Party on Monday evening I did a “Doom takeover” of the whole setup and let people play Freedoom, VNC-streamed directly from one of our IBM LinuxONE virtual machines. It was a huge hit. So much so that for the rest of the week we had folks dropping by the booth to ask if I still had it up, and a few commands later, I did! Using Windows laptops for all of this was certainly a new experience, so I was grateful that I thought to test it on a Windows 11 laptop we keep around for such things before the event. Did you know stock PowerShell on Windows 11 comes with SSH? Cool. But overall, aside from being fun to answer the question of “but does it run Doom?” with a demonstration, we all know that piping something over VNC isn’t that technically challenging, it’s the amusement and feeling it grants, and the fact that it’s coming from IBM, not some hip new startup where you may be more inclined expect it.

What else is cool? Quantum computers. They had an 80% scale model near the entrance to the Sandbox this year and it got near constant attention. It took until Wednesday until I was able to find a quiet moment to get a good picture with it. I’ve been reading about quantum computers since I first picked up an article about them in Discover Magazine back in the 1990s, so seeing them come together at IBM and be actively deployed to facilities around the world has been a thrilling experience.

And I know you’ll say the AI stuff currently taking over everything in the world is overblown, and it is, but there are some real use cases for it. IBM clients across industry and research have already come up with dozens of uses for AI/ML, just been waiting for the tech to catch up. As a result, IBM research has invested heavily for YEARS in AI hardware, which first came to market in an AI accelerator in the IBM Telum chip inside the IBM z16 and LinuxONE 4 a few years ago.

This year the Telum II came out in the z17 and LinuxONE Emperor 5, but the additional IBM Spyre AI Accelerator card using the same technology also hit the market. This SOC with 32 individual accelerator cores has definitely been the belle of the ball, with clients asking all week when they can get their hands on one (thankfully, it was swiftly announced that it would go Generally Available at the end of October). Theft jokes abounded once people learned that we had a non-working prototype inside of the IBM z17 plexiglass at our booth, and when I went to visit the new IBM Power 11 server at the Power booth I found they had a prototype you could HOLD at their booth! That’s where I got my photo with it. You see, these work in the Power systems as well.

Back at the IBM booth I got to hold a Telum II dual-chip module (DCM) which is always a delight. They also had display versions of the chips from the z15, z16 (Telum), and the new z16 (Telum II) which was neat to see side by side. I need to remind my friends who I spoke with a few months back about assembling a “petting zoo” of decommissioned hardware to bring to events, I love holding these things. Lots of nerdy technologists do, and when else would we get the chance for something like a mainframe component? Even if you have a mainframe, you really shouldn’t go poking around inside it.

Ferrari is also cool. IBM worked with Scuderia Ferrari on an AI-powered app (and more!), and if the keynote interview was any indication, both organizations are quite excited about it. Plus, we got to have what I’ve been told is one of the F1 cars from last year right there in the sandbox. It was beautiful. I bought a hat.

Also also cool? Lego. You know I love Lego, but a lot of other adults are waking up to the passion and it’s definitely boiling over in the tech industry with a lot of folks being more open about their collections in recent years. This has definitely leaked out into tech conferences I’ve been at these past few years. Booths offering custom minifig building, others doing custom Lego sets for attendees. It was super cute to see a Lego model of the Sandbox where the team there was collecting feedback of the event, both verbally and by having people vote with Lego.

And of course, when the IBM z16 came out we build a full-size model, which I wrote about here back in 2023. How do we follow that? I was absolutely delighted that this time around they focused on the IBM Telum II processor, by making a huge scaled-up model of it. Hanging next to the plexi, this model was based off of how the actual processor looks, but with whimsical details like frogs, robots, and airplanes to amusingly demonstrate various parts. I plan on writing more about this later, and my partner in writing this may have some surprises in store for something you can do at home too. Stay tuned!

Perhaps my favorite part of the event, and indeed a highlight of my year, was being invited to join PJ Catalano and Camillo Sassano to unbox a mainframe live on the expo hall floor. Normally such an unboxing is done quietly before the event so that people can see it in the final form, but PJ’s idea of a live unboxing built excitement. We had pre-event teasers, there were cool lights pointed at the crate during the opening party with signs to come back the next day, and it all resulted in well over 150 people trying to secure a great spot to watch it being unboxed.

It was my first time participating in uncrating a mainframe, so Camillo walked me through it live right there as PJ explained each step and why each component of the crate was in place. It was fascinating to see if all come apart and learn about how purpose-built the whole thing was. The crate door is not just a door, it’s the ramp! The mini flip up section on the top was so it could be built to fit inside a standard truck. And so much more. Once we gently rolled it out of the crate, we got it on the carpet and started putting the doors on. The doors can be put on either side, so on one side we put an IBM Z door, and on the other we put the LinuxONE door. Choose your mainframe! Or get a photo with both!

I hear the events team is putting together a full video of the unboxing from all the cameras they set up, but for now I was happy to be the first one to get to hug it for Hug Your Mainframe Day. Naturally, I hugged the LinuxONE side. After me, the whole rest of the event there was a steady stream of people getting their pictures with it, and hugging it. The IBM shop on-site even had t-shirts celebrating hugging mainframes, which was super fun (of course I got one).

At the end of the event, we didn’t do a formal packing up, but thankfully enough folks were still around to get the job done.

Throughout the event there were also a lot of pure fun things. A huge rainbow slide that Mae and I partook in a slide down. Lots of video games, including the ability to play Mario Kart on the keynote stage screen when it wasn’t otherwise engaged. There were spots for getting photos, one for silly photos and another across the expo hall for headshots. For an event with long days and so much serious content literally spread throughout the expo hall in the form of tech talks and sessions, it was nice that we had the ability to unwind and recharge before going on to the next thing. The event also featured an evening at Universal Islands of Adventure, where we really got to unwind! I was able to ride on Hagrid’s Magical Creatures Motorbike Adventure and the unforgettable Jurassic World VelociCoaster. I spent a good chunk of my late 20s and early 30s unable to go on such rides, which I also now realize was the height of when I suffered from migraines as an adult. Huh. Something was going on in my brain for a good decade there, but it seems like I’m in a better place now. While these rides are still thrilling and trigger a tinge motion sickness for me, it’s no more than the normal amount now, and the fun balances it out.

At the beginning of this post I mentioned that IBM has been doing cool stuff since the company began, which leads me to my last notable mention: the booth from the IBM Corporate Archives. I’m a fan of history, including the history of computing, so I have bias here, but I honestly believe in telling the continuous story of innovation at IBM. The booth featured a couple working vintage machines, including one that was hooked up to a large dot matrix printer and attendees could print out short messages on.

They also had a glass case display that changed daily featuring various pamphlets and memorabilia from various initiatives and notable releases over the years. The moon landing! The launch if the IBM System/360! All kinds of cool stuff. And what I considered the star of the exhibit and which welcomed attendees as they walked to the booth, an IBM System/360 Model 40 Operator’s Console. Love it.

I have really enjoyed seeing how this conference has evolved over the past three years to be bigger and better each year, and truly more fun and geeky. It’s a lot of work, but I can’t wait to see what they have and I get to participate in next year.
