• Cloudflare Containers ¹ enters public beta, immediately available for paid users with full Workers integration.
• Region: Earth global deployment, containers start in seconds, developers don’t need to select regions.
• Through Worker→Container binding, dynamically generates isolated instances by ID, suitable for multi-tenant platforms.
• Three instance types: dev/basic/standard covering 256 MiB, 1 GiB, 4 GiB memory requirements.
• 10ms billing granularity with separate CPU, memory, and disk metering, plus free tier included.
• Built-in Metrics/Logs retained for 7 days, supports external LogSink, reducing observability integration costs.
• Upcoming: autoscale = true enables global auto-scaling and latency-aware routing.

• Cloudflare Containers runs on AWS-developed open-source Firecracker microVM ² with KVM isolation, reducing multi-tenant side-channel risks while maintaining startup speed and resource efficiency.
• Firecracker microVM: < 125ms cold start, < 5 MiB memory, balancing security and density.
• Ernest Chiang demonstrated ³ running 4,000 microVMs in 90 seconds on i3.metal at COSCUP 2020 Firecracker workshop.

Witnessing Taiwan’s journey from nascent tech communities blossoming into full-fledged technical conferences, we’ve observed an organic proliferation of product-centric opportunities emerging alongside industrial metamorphosis and the ever-increasing complexity of cross-disciplinary integration. This ecosystem now encompasses the multifaceted spectrum of product operation, product marketing, product design, product management, and product development—a verdant and thriving landscape.

Yet beneath this seemingly lush canopy, one wonders: are we nurturing an organic greenhouse, or merely cultivating a wild tangle of weeds? As we navigate through this labyrinth of uncertainty, none among us possess the definitive answer. But perhaps not knowing is precisely what makes everything possible—it means we can still venture forth to explore, retreat home to experiment, and dare to iterate through our discoveries. On this sweltering weekend, we—a collective of souls orbiting the product ecosystem—gathered at the inaugural Taiwan Product Conference 2025, attempting to forge something meaningful together.

Conference reflections shall be compiled separately.

This piece unfolds in two movements: first, the release of presentation slides, followed by supplementary Q&A elucidations. I warmly invite you to utilize the feedback form found on the final slide to share perspectives from any angle, pose questions, or engage in dialogue. Looking forward to our next shared endeavor.

With the launch of AWS Taipei Region (ap-east-2), it’s time to update that overgrown web latency testing tool.

• HTTP overhead is quite heavy, but when you don’t have CLI tools available or when dealing with remote clients, it can provide a simple evaluation.

• Arranged roughly according to city distances.
• Based on AWS Region naming rules, supplemented by my modest geographical knowledge.
• Following the principle of not over-categorizing to avoid too fine granularity. If your principles differ, feel welcome to fork from upstream and modify it to your liking.

✳️ Background

I’m honored to have been selected after submitting my talk proposal—thank you to everyone who has quietly encouraged me along the way :) It’s also a privilege to be part of the 10th anniversary of AWS Summit Hong Kong. Thinking back to 2014, when Lenie, Locarno, and I invited Jeff Barr to Taiwan to deliver a keynote at COSCUP, to supporting the AWS Hero program, and now standing here in Hong Kong sharing with developers and technical managers at the AWS Summit Dev Lounge—it truly feels like a fortunate convergence of serendipity and iterative progress. My heart is full of gratitude.

This talk draws from over a year of experience working with traditional industries, streamlining processes, and modeling object states. It also reflects how our own product and technology integration (PTI) teams have adapted our workflows to collaborate with AI tools (with a fair share of pitfalls along the way). By combining Amazon Q CLI with an AI-augmented perspective on existing processes, we explore the mindset of inviting AI to be a new team member to join us. Like onboarding any new colleague, there will be a period of adjustment—but unless we invite this new teammate (or team?!) of AI to join us, that adaptation can never begin.

Today I spent some time setting up a development environment for the nRF52 DK (PCA10040) board on my macOS Sequoia 15.1.1 machine running on an Apple Macbook Pro M4 Pro (Apple Silicon). This blog post documents the process and can serve as a reference for anyone working with Nordic Semiconductor’s nRF52 DK (development kit).

Following Apple’s sudden release of the iPad Mini (7th generation) ^{1 2}, Amazon has also quickly launched a new color e-paper reader Kindle Colorsoft Signature Edition ³.

It seems everyone doesn’t want to miss the year-end Thanksgiving, Black Friday, and Christmas shopping seasons. Although I just got the reMarkable Paper Pro, and despite the different orientations (paper vs. books), seeing color e-paper products gradually coming to market still tempts me. For me, it could be more convenient for reading AWS flowcharts, architecture diagrams, and other information. Maybe I’ll wait and see if there are any Black Friday deals.
