  • father’s day

    Well, if you haven’t noticed, another Father’s Day has come and gone. Hope our dads got a call or a text. If you actually sent a present—wow, thanks for being better than most of us.

    I don’t really remember past Father’s Days. Not in any memorable way, at least. Maybe there was dinner or a card from school, but nothing that stuck. And truthfully, I didn’t mind and was thankful for anything I got.

    Lately, though, something’s shifted. I find myself wanting… something. I’m not even sure what. I mentioned this to Kacie, exaggerating dramatically, and she just stared at me ‘… He’s doing one of his monologues again…’ She didn’t say anything, but did cook an extra strip of meat that night which made me perfectly happy.

    Anyway, maybe you know the feeling. That quiet desire that all this effort—the quiet worrying, the logistics, the loving, the trying, shouldn’t just pass completely unnoticed. Most days I don’t know if I’m doing enough. But I’m sharply aware of the ways I could be doing better. It’s a strange class. No one gives you a grade, but you always feel like know you’re one assignment behind.

    Some of us relatively older dads, the ones who’ve weathered the peaks and valleys, health scares, ongoing ER visits, even tragic loss, move differently. Quieter. Slower. Gentler. Watching the newer dads sprinting through the thick of it, in varying degrees of emotion. We don’t say much, but we choose our words carefully, because not much needs to be said. We all understand what’s going on. We remember that situation, that tempo. It’s a long run. Just take care of yourself too. Especially today.

    So yes. It’s a special day. And just like we understand Mother’s Day is more special each year, we acknowledge it’s the same for Fathers Day.

    Maybe not loudly. But more real, more understanding, a few more nods to each other. A moment to gather around, like at a late-night café, quietly talking and laughing. Or maybe you just lean back, sip a glass of wine or a cold one, and close your eyes, half listening. The “Happy Father’s Day” messages feel a little more heartfelt each year. As if, if not for me, for everyone who’s tried so hard this past year. The ones who don’t respond, well, we get it. Take your time.

    So if you’re a dad: heartfelt congrats, and cheers to all your incredible work. You’re doing awesome.

    As for me, I still got to stop by my favorite place today, and had a great hike the day before. So all in all, not bad.

    And that reminds me, this whole post is completely about myself. If my dad reads this, he’d be like thats all fine and good son, so where my recognition? I need to call him. Happy Father’s Day to the best dad in the world.

    To visit again some day

    Is it just me or is it typical for folks to get a bit more nostalgic as they age.

    Because truth to be told I’ve been reminiscing about my college time recently. Perhaps its the fact that within a few years of graduation life would be throwing me a ton of knee buckling curveballs. Or perhaps because they symbolize a cheap and free escape. Either way it makes those memories more softer, and a little more rose tinted.

    To be sure, my time in Ann Arbor wasn’t that eventful. Most of it was trying to stay afloat during classes, wondering why these winters never ended, and being alarmed at how the squirrels got as big as dogs. At that time I also didn’t have the tools for proper time management and going from a strictly scheduled high school exp to complete independence was a huge change. So I had to learn some self managing and other tools along the way.

    Still, it was a beautiful time with some of the most kind, good, and memorable people I’ve ever met in my life. Though I’m in touch with precious few, and you forget the exact interactions, the echos of warmth shown always resonate in your memories. Perhaps even more as life teaches you what truly matters.

    It’s also a testament that large or small, they’re doing far more everlasting and consequential things in the world. So I’m glad to have shared a season or two, thankful at the impact they had on me, continue to have, and I’m sure in many others lives. Even if it shows up a bit later in life.

    So for those of us that graduated some time back and witnessed many a good friend, we’re truly lucky even if we didn’t make as much of our time there as we wanted…. Especially since the cost of tuition back then doesn’t seem that bad nowadays… though it still took me such a long time to pay that back…

    But hey at least national championships feel absolutely amazing.

  • bagels

    bagel bagel bagel
    I just love this place

    Do ones favorite hole in the wall type places make themselves known immediately, or just grow on you? When do you know?

    There’s this bagel shop we frequent because we have weekly appointments at the place right next door. It’s the definition of peace. What looks like a menu created in the 70’s, well over 30 difference sandwiches/bagels, and the couple behind the counter look like they’ve married and worked together happily for the last 30 years. To top it off the wall has a map of Silicon Valley… produced in the early 00’s. So only a few years old yes, yes.

    Here’s the thing, I don’t even like bagels. Nor bagel sandwiches. I guess I do like cream bagels, but that’s more the cream probably. They’re tough, tasteless, filled with empty carbs, and way too thick to use as a sandwich. Remind me what was the point again with these? It wouldn’t surprise me if whoever invented this felt deeply ashamed disappointed in themselves.

    Yet over the course of a year or two… I somehow now find myself starting to look forward to the place. The peaceful predictability, the cozy interior, the outdated decor. The barely comfortable bar seats, that old map on the wall. The box of toy cars…. yes the plastic slightly heavy toy cars every boy played with as a kid. Also the prices are cheap. Like best deal in the bay area cheap. Ten bucks say the couple owns the-

    So here I am, munching away happily away at bagel menu number 17c… I think. It’s the classic salmon with cream cheese. It tastes exactly like how I expected it to, the coffee tastes exactly like I expected to, the cheerful aforementioned elderly couple working as usual, always a few people in a line, no doubt enjoying it just like me. Is my subconscious yearning for peace having long dealt with rewarding but also at times chaotic workplace dynamics?

    Yeah I guess I’m a regular now and its my favorite place, I just didn’t know it, or want to admit it.

  • hiking

    Rancho San Antonio Park

    Starting late last year, a few of us dads began meeting for 2.5-hour hikes on Saturday mornings. Not weekly, but spaced just enough such that you felt like going again and it felt like a thing. It checks all the boxes; boosts your mental, social and physical health, it’s invigorating, time commitment doesn’t disrupt family routines, and it’s completely free. Even our snacks are from Costco.

    To be sure, it’s not just a random group as most of us are first-generation Korean immigrants and we got to know each other through shared responsibilities and common concerns. The moms connected first; it took significantly longer for the dads to gel. But once it gets going, age doesn’t matter, everyone is exceptionally respectful and happy to connect.

    The routine is familiar now. Wake up at 5:50 a.m., briefly contemplate skipping, but get ready anyway because either you’re driving or someone’s on the way to pick you up. Cancelling right then would obviously invite a lot of frowning. Triple-check layers, snacks, water, watch, headlamp if its still dark. By the time you’re standing out on the curb, half-awake but committed, there’s already a quiet satisfaction. Once in the car, conversation flows easily. Still yawning, but the early fog, both literal and mental, lifts quickly when you’re together and the sun is rising.

    The hikes themselves are peaceful and surprisingly rich. We walk, we talk. We share perspectives, memories of Seoul, and the small cultural mismatches that come with American life for those relatively new, among many other topics. Sometimes it turns into a casual venting sessions, which honestly, is part of the value as we laugh or commiserate together.

    There’s a spot we often reach around the midpoint. A cluster of trees with a small clearing in the middle, perfect for coffee and snacks from Costco. Someone placed logs around strategically for this very purpose. Instant coffee pouches and a thermos of hot water go a long way.

    Going on a tangent, it’s interesting Bay Area trails have any cheap food options near the trailhead, like they do across the pacific or in Europe. I still remember uncles back when I was a kid who’d skip the hike entirely, grabbing a seat at the outdoor tables and ordering drinks while the rest of us climbed. “Oh don’t worry about me, you folks go right ahead”. Even young me knew these folks had zero intention of hiking from the start and they looked quite happy too.

    Anyway, here you’re lucky if there’s a single picnic bench. Our American hiking culture is very… utilitarian. You’re there to hike hike. There isn’t room for a snack shack that’ll add back up all the calories you just burned.

    Still, we’ve made it work splendidly, and somehow the coffee we pour in that quiet grove tastes better than any café could offer. It’s a low-key group of good, warm-hearted, family oriented guys. No expectations, no pressure. Show up if you can, skip it if life gets in the way. Without planning it, we all seem to take turns disappearing for a few weeks and then returning. A 30% participation rate is a win, even one other person is a blessing. Perhaps the only hesitation is when its still quite dark and the trailhead has a sign that says beware of mountain lions(!).

    One recurring joke: when someone asks if it was hard to get permission from their wife to join, the usual response is something like “Hard? She practically shoved me out the door. “Please go outside and make some friends. Here’s your snacks.”

  • in laws

    If I had to name two of the most amazing people I’ve ever met, excluding my family, it would be my father-in-law and mother-in-law. And if I had to name four, I’d probably include my brother-in-law and his wife. There are some other amazing folks but lets be honest they’ll never read this. In fact, if you’re reading this and you’re not related to me, thanks.

    From the very first time I met them, they’ve embodied grace and quiet strength. They don’t judge. They simply encourage, support, and bring peace into any room they enter. I still remember nervously practicing our wedding ceremony and my father-in-law gently saying, “Take good care [of her].”.(…is a simple yes the only acceptable answer to that) And during those chaotic early newborn months, my mother-in-law insisted on sleeping on the couch in our tiny one-bedroom apartment just to help however she could.

    Their lives haven’t been easy. My father-in-law served over 15 years in the Korean army before transitioning into civilian life. That discipline and resilience still shine through, though he does get disappointed if he reads news of some discipline issues. I imagine it’s like your team releasing a critical bug onto Production. Today, he manages multiple teams at an architecture firm, and I learn so much just from our conversations—how he sets priorities, when to stay hands-on, when to step back. My mother-in-law remains professionally active and is deeply loved by every family she works with. Their generosity, communication, and steadfastness in the face of adversity continue to humble me.

    I hope we’ve tried to show our appreciation over the years, visiting them or road tripping to places like Yosemite and Tahoe, but I know at their core, what they want most is for us to live with joy and peace… and for me to pull my weight when it comes to household chores. Without saying, I know we’re constantly in their prayers, which means a lot.

    …Writing all that reminds me I really ought to call them more often. Hopefully I’m not the only son-in-law who procrastinates on that.

  • boxing

    If you’d told me at the start of 2024 that I’d take up boxing, it wouldn’t have even made the bingo card. I would have laughed at you as I never once in my life every contemplated that. I’d had enough of combat hobbies getting whacked by grown adults when my dad forced me to learn kendo as a kid.

    And yet here I am. To be precise, it’s VR boxing: headset on, gloves tracked, and opponents matched online. It actually feels stunningly close to the real thing, or what I assume is the real thing if I’d actually stepped in a ring before. The ducking, weaving, striking, all compressed into the tiny 4×3 meter space in my living room, delivers the kind of high-intensity cardio I’d never imagined I’d look forward to. I know, it still sounds a little ridiculous and more than a little weird.

    But here’s the reality. Sometimes I find myself wide awake after the rest of the family is asleep. The weight of future responsibilities, current deliverables, and the clouds of the past come all at once sometimes. So I put on the headset, spar a few rounds, and end up collapsed on the sofa, drenched in sweat and somewhat at peace.

    Does it help? Without a doubt. The headset isn’t cheap, but I convinced myself a single doctors visit costs more. And for someone who never quite gets a runners high, doesn’t have time for regular visits to outrageously expensive Bay Area gyms, and lives in a small condo with limited space, this is the closest thing to a godsend. It saves me monthly gym fees and I even find myself browsing the game’s subreddit more than I’d like to admit.

    Not surprisingly, the whole experience brings back memories of my middle school kendo classes. Did you know you actually can smell the sharp scent of burning bamboo when strikes land on your helm during sparring? Grown adults at the dojang showed zero mercy. At the time, I didn’t understand it, but now? Maybe they were just trying to shake off the stressors of their own lives, just like I’m doing now.

    Anyway, I’ll probably get a few more rounds in before winding down for the night and preparing for morning meetings. And to the developers who built this game: thank you. You created something incredible, and are improving the physical and mental health of many, many, people.

  • streets

    my elementary school on the left

    There’s something surreal about walking through the streets you grew up on. No matter how many years have passed, if you close your eyes for just a second and let your mind drift, time folds in on itself. Suddenly, you’re back in the days when your biggest priority was chasing after friends. Often for not a particularly good reason, that also definitely wasn’t pre-approved by Mom.

    In 2023, I returned to Seoul for the first time in about 12 or 13 years. A number of very challenging family health issues had kept me from visiting, I had even stopped contact with all my childhood friends during those years. But the moment I stepped off the plane into that heavy, humid air, it felt like I’d never left. Whenever I had free time, I’d just walk—aimlessly—turning my head constantly to take in every side street, every restaurant, every pastry shop that caught my eye.

    Friends would recommend visiting that beautiful park or lake in the city, but we have tons of that in California. What I wanted was chaos. The busiest, craziest, tightest areas possible jam packed with impatient cars and frowning people in a hurry to get to places while frowning. And it was glorious glorious. The symphony of traffic, winds, sounds, walking, air, cicada sounds were identical to decades ago. Again, it was like I never left.

    At night it was even more vivd. The darkness shrouding the streets contrasting with the bright lights inviting you in, car taillights moving away along with the lively pedestrians coming and going… yep exactly the same. It was like some comfort blanket where I felt like I could walk on forever. Probably the streets being safe at night helps too, but thats another, can of worms type topic.

    I do however, confess the fact that I’m on vacation(well, I still check Slack and Outlook out of habit) contributes to this, and if I stay longer I’ll probably notice the stuff I’m glad I left behind. But til then its an interesting and refreshing, though a bit melancholy experience I get to go through whenever I visit.

  • cost

    Sometimes after meetings or syncs I go down to get lunch with colleagues. Often times folks I don’t know very well, given our need to interact with a large variety of engineering teams. And that leads to, well, a lot of small talk. Between professionals the topics are your typical where do you live, weather, vacation plans etc.

    But there’s one topic that tends to draw out more genuine conversation: relocating to the Bay Area for work. It comes up often because almost everyone at the table, whether immigrant or American, moved here from somewhere else. America alone is a huge country.

    Then the tones shifts and we’re usually thinking the same thing, reminiscing about the lives, friends, and relatives we left behind, especially our parents. All agree it’s only years and years after that you notice the high price you paid. We sort of laugh and say how envious of our friends back where we grew up, how they stay connected and are still close to their families(though curiously they largely seem to meet up among themselves only when we visit).

    Thus, pretty much everyone here is rebuilding their friends and support groups. Or as often is the case, we aren’t. And it’s so easy to let time slip by while not making that investment, not knowing it gets ever so harder to build new relationships and become isolated.

    But the silver lining is that it’s actually not that hard to develop relatively deep friendships. It just requires consistent meeting for whatever reason, for around 18 months. You don’t have to do anything fancy or expensive at all, each others presence is good enough. Obviously even faster if the group has common interests or has the characteristics of a support group no matter how big or mundane.

    In the end, talking about this does help at work. We get to connect with our colleagues a bit better, which is critical when inevitable tricky situations at work arise.

  • feedback

    “Albert, I feel like you’re in the weeds too often”

    I still remember when my boss said that to me about a decade ago. We were sitting in a patio outside the office, it was one of those typical bay area bright sunny days, and he wasn’t exactly facing me, sort of looking off into the distance.

    This was before when I realized requesting feedback, and making giving feedback as easy as possible, was key to your career. And I richly deserved this particular feedback. I’d spent the past month heads down, debugging our many machine learning data pipelines, trying to figure out why moving our terabytes of training data was so slow. It’s doubly infuriating when you know the sheer cost of these machines plus the storage costs PLUS the uncertainty if finally this time we’ll produce a Production grade model.

    It wasn’t for a lack of trying. Multiple, multiple nights spent watching flows, rewriting queries, trying to look at object size, choosing different data formats, different processing frameworks. But a key miss was that I wasn’t providing my manager with proper estimates, timelines, and options, however ballpark they were. I wasn’t giving him the data needed to make decisions how much resources to invest.

    Whenever I look back, I feel a pang of guilt for not doing my job as a senior engineer, and treasure that moment because it was sort of the turning point in my career. Estimating, progress reporting, giving your manager right sized details so they can decide on the next steps, etc. I’ve been trying to make that a cornerstone of what I do.

    But these days I realize something yet again new. Summarizing is good, but at the same time you HAVE to know the details as well. Else what exactly are you summarizing?

    Everything in life is a circle isn’t it.

    One day I have to track that manager and buy him a coffee. Or two.

  • late night meetings

    As I await a late night sync with a different time zone, I sometimes think how lucky I am

    We work very closely with our offshore colleagues. Whether its trouble shooting, debugging, planning, setting directions, or perhaps equally important, just syncing to connect on a personal level to talk about none work issues. Doesn’t matter whether they are fellow employees, contractors or 3rd party partners, each and every person is invaluable.

    Much of the time they participate in US time zone meetings, where HQ is. Often multiple nights a week. I guess myself always scheduling my own meetings with them in their time zones, which many of same time zone colleagues also do, is a bit of a respect thing, to share the load as we all have families, and time to relax in evenings is important. After all no matter our differences in opinions, scarce resources, and tight timelines, we all know we’re working to beat the competition.

    So far it seems to be working pretty great, feel like I have a great working relationship. And am thankful my team and others in our TZ seem to have no issues with late night meetings when needed. Just need to make sure it’s not so often burnout becomes real.
