As applications become increasingly distributed, durable execution has emerged as a critical paradigm for building resilient systems that survive failures whilst maintaining complete execution state. This session examines why durable execution is essential for modern architectures from multi-step processes spanning multiple services to long-running operations requiring distributed coordination. We'll explore real-world applications and human-in-the-loop processes that traditional patterns cannot handle reliably. The discussion covers challenges and learnings from building automation tools in GovTech, examining how durable execution solves common distributed systems problems like state management, fault tolerance, and observability. We'll delve into design principles that make workflows resilient by default and automatically handling retries. Whether you're evaluating tools like Temporal, Cadence, or others, this conversation offers practical insights into implementation strategies, use cases, and pitfalls to avoid. **[Learn with us today](https://go.gov.sg/stackmeetup-12mar2026-mc)**! **Programme** 7:00pm: Introduction By STACK Community 7:05pm: Opening By ​Steven Koh, Director, Engineering Management, Government Digital Products (GDP), GovTech Singapore 7:15pm: Building Opus: Delivering Durable Workflow Execution for Government Systems By Gabriel Tay, Staff Software Engineer, GDP, GovTech Singapore 7:35pm: Temporal Primitives to Real-World Design By Tao Guo, Staff Solutions Architect, Temporal.io 7:55pm: Real Application Use Case of Subscription Workflows Through TechBiz By Yong Weng Kiat, Software Engineer, GDP, GovTech Singapore 8:15pm: Q&A 8:30pm: End of STACK Meetup Click **[here](https://go.gov.sg/stackmeetup-12mar2026-mc)\*** to sign up! \*Registration will be accepted via GovEntry only.

Come join us for an evening wind down walk after work - a pause in the bustle of the week to breathe, stretch your legs, and unwind with good company. You can chat, listen, or walk quietly - all are welcome. **How it works (super simple):** * **10 mins** * We’ll meet, say quick hellos, and wait for individuals who may have difficulty finding the location or are rushing to end off a call (it happens, but please understand that we will move off after). Will be in black shirt, beige knee-length shorts. * **35 mins** * We’ll walk from Tanjong Pagar to Marina Bay Sands with a beautiful skyline (2.5km, \~4000 steps). Optional extension to Gardens by the Bay if time allows. * Feel free to get to know others on the walk. Some optional light prompts on hand are... sharing a question or thought that you're hoping to reset from today, a hobby that you've been exploring, music preferences, latest quirky obsession etc. Leave some mental load behind. **A quick note:** * This isn’t a networking or sales event. Please no pitching, recruiting, or solicitation. No pressure at all to introduce yourself through work. * Priority to folks who have attended a session previously. Please update RSVP if you can't make it so we can gage the group size prior. * Will keep a lookout for weather forecast in case there's rain to be expected in the area. **Friendly Reminders:** * Do come in comfortable footwear. * If possible, leave bulky equipment behind. * Have fun, feel the breeze, and unwind...

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them. Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance". Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.
