Dropping Datadog Without Losing Your Bark: Open-Source Observability
Observability is supposed to help us understand our systems but for many teams it has quietly become one of the most expensive and least flexible parts of the stack. Plenty of organizations take polished SaaS platforms like Datadog to get real value quickly early on, only to hit the same wall later: runaway costs, pricing tied to architectural decisions, and vendor lock-in so strong it makes Rogers and Bell both blush.
In this talk, I’ll walk through a real-world case study of a JVM-based production system that migrated away from a Datadog-centric observability setup to an open-source, OpenTelemetry-based platform. We’ll dig into the why behind the move, the architectural decisions that mattered, the mistakes along the way, and how the team ended up with pragmatic visibility into latency, errors, and resource usage at a fraction of the cost.
The second half of the talk is practical and forward-looking. I’ll show how OpenTelemetry unlocks real choice by acting as a neutral data plane for your telemetry. From there, we’ll look at modern, off-the-shelf observability backends you can plug in within minutes without rewriting applications or installing new agents. Want to dual-write, swap vendors, or route data somewhere new? This is how you do it without a big-bang rewrite or another long-term commitment with a new vendor.
This session is for engineers and CEOs who are feeling the observability cost squeeze, want leverage back from vendors, and are looking for realistic ways to modernize monitoring without lighting their entire stack on fire each time they decide to change their tools of choice.
**About the venue**
Free Times Cafe has bistro-style seating and a full food and drink menu. Please consider helping to support the venue by planning to have supper during the talk.
**Speaker Bio**
Alexei Zenin is a Platform Engineering Consultant based out of Toronto, Canada. Over the course of his career he has worked across the Healthcare, Marketing, Video Games, and Banking industries. He loves to tackle hard problems in the distributed systems space with a focus on scaling platforms both from a technical and process perspective. He is a strong advocate for highly maintainable and well tested code while at the same time pragmatically delivering value to the end user.
He has contributed to the broader tech community, namely to Confluent’s blogs on Apache Kafka, spoken at Current 2022 in Austin, Texas, and spoken at XP Game Summit 2025 in Toronto, Canada. During his 5 years at Uken Games he contributed to several games like Who Wants to Be a Millionaire and Jeopardy. One title of note he saw from inception to completion was a game for Tim Hortons built right into the official app, Tim’s Word Challenge. Millions of Canadians have played it along with their morning coffee. He also got to work with Netflix on several unannounced games during his time at the studio.
Currently, Alexei is working with various clients, both large and small to modernize and streamline their platforms with the most appropriate tools and practices. Outside of his professional life, he gives back to his community by volunteering at UofT. He also enjoys paddleboarding and attending live rock concerts to reset after long coding sessions.
Fun & easy way to play more tennis (please read event description for details)
We’re still working to get more people into these Meetups, but our goal is to give PlayYourCourt members a few social tennis outings each week in addition to your practice sessions and Challenge League matches.
These Meetups are co-ed, super laid back, and all skill levels are welcome. Post your skill level and a suggested court in the comments section so we can round up as many players as we can for some tennis fun!
Also, if you’re looking to meet new practice partners or play some matches and you aren’t already in the PlayYourCourt Community, you can go here to see what we’re all about and sign up:

If you love tennis, we’d love to have you! Be sure and watch the quick video that explains how everything works.
Happy hitting!

Practical Philosophy Meetup for Youth - Mississauga 🇨🇦
**✌️ PRACTICAL PHILOSOPHY YOUTH EDITION**
This is a special Youth Edition of Practical Philosophy, created specifically for young people aged 15–19.
It’s a space where young people can explore big ideas, develop independent thinking, and practice expressing themselves in a respectful, open environment among their age group.
**🏛️ WHAT'S PRACTICAL PHILOSOPHY ABOUT?**
Practical Philosophy is a weekly meet-up that brings critical thinkers together for an opportunity to dive deep on a topic, practice communicating, and building a community. All with no ‘official’ philosophy knowledge required! 😎
Practical Philosophy is based on the idea that philosophy should be accessible to all, and not something reserved only for academics. Each week we choose a topic, and the goal is to use the conversation to develop our critical thinking and communication as we explore that topic.
The goal is to help develop our Critical Thinking, Communication, and Community 🙌
**📓 HOW DOES IT WORK?**
Each week, we pick one topic and discuss it. The topic for the week is shared, generally in the [Whatsapp group](https://tally.so/r/NpAjbj), along with jump-off points to get the conversation going.
When groups get bigger than 7-8 people, it’s important that we break into smaller groups. This way we are able to maintain a conversational flow as opposed to having our meetups feel like a discourse or lecture.
**General Meeting Agenda**
Each Practical Philosophy meet-up follows this general timeline:
* 18:00-18:15 - People arrive and chat, get to know each other before the official start.
* 18:15-18:25 - Meeting introduction, explanation of Practical Philosophy and the topic for the week, read the guidelines and the overview so attendees know what to expect in terms of timelines.
* 18:25-19:45 - Break into small groups - introduce yourselves and general thoughts on the topic, open discussion afterwards. At this point the group can review the ‘jump-off’ questions as needed, but they are just there to help guide the conversation. It’s not obligatory to answer them.
* 19:45-20:00 - Bring everyone back together to discuss conclusions of the topic - each group gives a short 1-minute summary. Organizer concludes the meeting and everyone takes a group photo.
* 20:00 - The official meeting is over but it’s a great opportunity to get to know people in a non-structured environment, so we often stick around, chat, and get to know each other.
**🧧PRICING?**
Practical Philosophy Club is FREE to attend! We just ask that if we are meeting in a café, buy a beverage! Some chapters rent a space for us to meet, and they may ask for donations to help contribute to the cost of rent. Donations will always be 100% voluntary though!
**💛 WHAT PEOPLE SAY ABOUT PRACTICAL PHILOSOPHY**
**🗣** “I feel like Philosophy Club helps someone build their own belief system through a series of perspectives while not promoting what’s right and wrong” - Ekam
🗣 “I got hooked from day 1 (the topic was authority) and felt it was the right place for me. I feel it is a place where people can go to learn and discuss new perspectives and increase critical thinking and community by interacting with people who might challenge your point of views but at the same time encourage you to have openness and mind flexibility.” - Daniel
**🤓 FAQ**
* **Do I need to study or read anything to attend?**
No preparation is necessary. This isn’t a study of other thinkers. We want to know what you think about the topic, not what an old philosopher thought. If you have a perspective from a religion or a school of thought to share, throw it on the table and we’ll discuss it.
* **Is there a specific philosophy that Practical Philosophy is focused on?**
The goal of our meet-ups is to not have dogmatic discussions, and flex our critical thinking muscles. Because of this, we want to hear from every realm of thought, and don't study a particular school.
* **What age group is this for?**
This youth edition of Practical Philosophy is designed for young people between 15–19 years old. Topics and discussions are adapted to the interests and experiences of this age group.
* **Can I come alone?**
Of course you can, we encourage it :)
* **Can I be late?**
Please don't be! We do have a 15 minute grace period where we allow people to funnel in while we hang out, but after that if you arrive too late, it disrupts the flow of the conversation.
* **Where do you meet?**
The location is posted in Meetup and our [Whatsapp ](https://tally.so/r/NpAjbj)group for this location. It is HIGHLY RECOMMENDED that you join the Whatsapp group! If you want to know what other cities have a Practical Philosophy Club, you can see our chapters on our [website.](https://www.practicalphilosophy.club/practical-philosophy-locations/)
🤝**POLICY**
To respect our members privacy, we ask that no one privately message a member without first getting explicit consent. (This looks like speaking in person and being asked to message privately.) Contacting or texting other participants without prior consent is not permitted and may result in removal from the group. Practical Philosophy reserves the right to enforce this policy at its discretion to maintain a safe and respectful environment.
**PRACTICAL PHILOSOPHY CLUB - Philosophy, everywhere. ✨**
We started in Practical Philosophy back in 2021 and there are now 50+ chapters in 25+ countries, including Canada, Spain, Japan, Mexico and many more! 🗺️

Post Eclipse: Kundalini & Light Language Activation
**In-Person Light Body Expansion Activation**
Join us for a powerful in-person Light Body Expansion Activation — an immersive energetic experience designed to awaken your life force energy and expand your consciousness.
This session combines **Kundalini (life force) activation and Light Language transmission**, creating a space where deep healing, emotional release, and expanded awareness can unfold naturally. As you lie comfortably on your mat, you will receive a transmission of energy that supports the awakening of your own inner life force and the expansion of your energetic body.
Participants often enter deep meditative or altered states as the body responds to the vibrational frequencies of sound, energy, and light language. These frequencies communicate directly with your consciousness, activating the body’s innate intelligence and natural healing capacity.
This experience supports a deeper connection to your authentic self while helping release energetic blockages and limiting patterns.
**During the session you will experience:**
• A heart-opening ceremony to deepen connection and receptivity
• Demonstration of the activation process
• Full Light Body Expansion Activation energy transmission
• Light Language channeling and vibrational sound frequencies
• Somatic and energetic release as the body responds to the energy
• Closing integration and sharing circle
**Participants may experience:**
• Spontaneous body movements or energetic sensations
• Emotional release such as laughter, tears, or deep peace
• Visual or intuitive insights
• Expanded states of consciousness
• Activation of the voice through humming, singing, or light language
**Potential benefits:**
• Release of emotional and energetic blockages
• Expansion of awareness and consciousness
• Greater intuition and clarity
• Reconnection with your inner guidance and purpose
• Increased creativity, joy, and emotional freedom
All you need to do is lie down, relax, and allow the energy to guide the experience.
Please book your spot [here](https://lightbodyexpansion.com/class/4)

Mob Programming at Mofer Coffee
Let’s do some coding together at a cafe! No more working alone in the weekend. Here, we write code together. And I mean together together. Not occupying-the-same-space-but-separate together.
Here’s how it works: Jennifer brings her mobile app project, tells everyone that it is like Pinterest for recipes and she’d like to work on the nav bar. Paul and Chloe think Jennifer's project is fascinating, and they join the group. They gather around Jennifer’s laptop and work on the nav bar for 2 hours. Jennifer is the one typing out the code while Paul and Chloe research, brainstorm, and offer suggestions.
If you’re feeling stuck on your own project or need a motivation boost, bring it to mob programming!
Want to learn by watching how others code and solve problems? Join someone else’s project at this event!
Oh and we love your half-done projects that you are a bit embarrassed to share. Absolutely bring those to the event!
**Discord**:
We use Discord to share screen & code snippets during the event. Also feel free to share your projects here before the event!
https://discord.gg/yvAGbh4PpD
**Event policy**:
* We have 0 tolerance for harassment.
* We don’t allow the projects that are not meant to be shared in public such as school assignments, interview tasks, or trade secrets.
* The goal is to write code. We discourage you from pitching business ideas here, doing code reviews, or spending the whole event on planning what to do.
* Please buy a drink, and tip the barista well.

From Web Forms to Web Components - Burton Smith
**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you.
The building address is 4450 Bridge Park
The entrance is 6620 Mooney St, Suite 400
**Abstract**
Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively.
This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way.

# FAQs
**Do all ideas have a chance at getting funded?**
Not all ideas will move forward after initial pitches on Saturday. Once pitches are complete, we’ll vote for top ideas and form teams around the 4 – 7 ideas with the most votes. You must recruit **at least four total team members** (including the founder) to move forward and have a chance at getting funded on Sunday. If your idea doesn’t move forward, you can join another team!
**Do I have to submit my idea online prior to the event?**
Unlike previous years, we don’t have the option to submit your idea online prior to the event. Instead, everyone will be going through a brainstorming exercise on Saturday that’ll help you prepare for your initial pitch.
**Will we be working for 24 hours straight?**
Nope. The event is split over two days. You’ll be building on Saturday and pitching on Sunday.
**Do I have to pitch an idea?**
Nope. You can also simply join a team.
**What types of entrepreneurs does GBH support?**
While GBH most often works with technology startups, we support *any* organization (for- or non-profit) that makes an impact on health in the US or across the world.

These Meetups are co-ed, super laid back, and all skill levels are welcome. Post your skill level and a suggested court in the comments section so we can round up as many players as we can for some tennis fun!
Also, if you’re looking to meet new practice partners or play some matches and you aren’t already in the PlayYourCourt Community, you can go here to see what we’re all about and sign up:

If you love tennis, we’d love to have you! Be sure and watch the quick video that explains how everything works.
Happy hitting!

DoJo (Informal Python Meeting)
**New Dojo Location!**
**Knotty Pine Brewing**
1765 W 3rd Ave,
Columbus, OH 43212
We're going to try a new dojo location for a few weeks and see how it works
Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead.
We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)
