"Feedback is a gift. It's an opportunity to learn and grow"

At Google, we believe in the power of feedback to drive improvement. Sometimes feedback can be tough to hear. But taking the time to unpack it, understand the perspective, and reflect on it is crucial. 

Why feedback matters:

- It reveals blind spots we cannot see ourselves
- It accelerates learning by shortcutting trial and error
- It demonstrates that others are invested in your success
- It creates alignment between perception and reality

How to receive feedback effectively:

1. Approach with curiosity, not defensiveness

When receiving feedback, your first reaction might be to justify or explain. Instead, listen deeply and ask clarifying questions: "Can you give me a specific example?" or "What would success look like to you?"

2. Separate intention from impact

Remember that well-intentioned actions can still have unintended consequences. Focus on understanding the impact rather than defending your intentions.

3. Look for patterns across multiple sources

Individual feedback may reflect personal preferences, but patterns across multiple sources often reveal genuine opportunities for growth.

4. Prioritize actionable insights

Not all feedback requires action. Evaluate which points will have the greatest impact on your effectiveness and focus your energy there.

5. Follow up and close the loop

Demonstrate your commitment by acknowledging the feedback, sharing your action plan, and following up on your progress.

Creating a feedback-rich environment:

- Model vulnerability by asking for feedback yourself
- Recognize and celebrate when people implement feedback successfully
- Make it routine through structured check-ins rather than waiting for formal reviews

At Google, we've learned that organizations with robust feedback cultures innovate faster, adapt more quickly to market changes, and build more inclusive workplaces.

Let's commit to seeing feedback not as criticism but as a valuable investment in our collective future. The discomfort is temporary, but the growth is lasting.

"Mastery isn't linear, it's layered"

We often think of mastery as a straightforward path: learn, then work, then succeed. But true growth isn't linear -  it's layered. 

It's the constant interplay of learning and doing, each fueling the other in a continuous cycle of development. Think of it as weaving a tapestry, each thread building upon the last, creating something richer and more complex than a single strand could ever achieve.

This layered approach is where the magic happens. It's not about accumulating knowledge in isolation, but about applying that knowledge, discovering its limitations, and then seeking new understanding to bridge the gaps. Work informs learning, and learning refines our work. It's a dynamic dance of action and reflection, a virtuous cycle of growth.

Embrace the process. Don't be afraid of the challenges or the moments where you feel you don't have all the answers. Every attempt, every perceived setback, is simply another layer in your journey to mastery. 

Trust that the continuous cycle of learning and doing will ultimately unlock your full potential.

"A quick call can turn into a long fall from productivity."

Anyone who has experienced deep focus knows this truth. One moment you're in the zone, making significant progress. The next, you're derailed by an interruption that could have been handled differently, and your momentum vanishes. Regaining that focus takes considerable time and energy.

This reality is stark: while we expect our productivity to maintain a steady course, interruptions cause sharp drops followed by slow, gradual recoveries.

To protect your productivity:

- Set clear communication boundaries about when you're available for calls versus other forms of contact

- Embrace asynchronous communication for non-urgent matters

- Create dedicated, notification-free blocks for focused work

By implementing these approaches, you can significantly reduce interruptions and maintain your productive momentum.

"Why cognitive load (not clean code) is what really matters in coding"

What truly matters in software development isn't following trendy practices - it's minimizing mental effort for other developers. I've witnessed numerous projects where brilliant developers created sophisticated architectures using cutting-edge patterns and microservices. 

Yet when new team members attempted modifications, they struggled for weeks just to grasp how components interconnected. This cognitive burden drastically reduced productivity and increased defects. Ironically, many of these complexity-inducing patterns were implemented pursuing "clean code."

The essential goal should be reducing unnecessary mental strain. 

This might mean:
- Fewer, deeper modules instead of many shallow ones
- Keeping related logic together rather than fragmenting it
- Choosing straightforward solutions over clever ones

The best code isn't the most elegant - it's what future developers (including yourself) can quickly comprehend.

When making architectural decisions or reviewing code, ask: "How much mental effort will others need to understand this?" Focus on minimizing cognitive load to create truly maintainable systems, not just theoretically clean ones. 

Remember, code is read far more often than written.

"As you get smarter, you stop having an opinion about everything."

With deeper knowledge comes the recognition of complexity. You begin to see issues from multiple angles and understand that few questions have simple answers. This realization can be initially unsettling.

Yet this uncertainty brings benefits. It fosters open-mindedness and tolerance while improving your decision-making through more comprehensive consideration of information.

A crucial skill is knowing what doesn't deserve your attention. Focus your mental energy selectively. Equally important is recognizing when your opinion need not be expressed. 

Sometimes listening proves more valuable than speaking.

"Why I use Cline - a free VS Code plugin - for AI engineering"

✍️ My new write-up: https://lnkd.in/gnstGaDK

The AI coding assistant landscape is crowded. Tools like Cursor, WindSurf, and GitHub Copilot all promise to streamline development, but after extensively testing them, I keep coming back to Cline - a free VSCode plugin that treats AI not just as a code generator but as a systems-level engineering tool.

What sets Cline apart? Flexibility, control, and deep system integration.

🚀 Core capabilities that matter

✅ Strategic model switching: Cline lets you use any hosted or local model or even combine models for efficiency. A standout workflow? DeepSeek-R1 for planning, Claude 3.5 Sonnet for execution- reducing costs by up to 97% while improving quality.

✅ Smarter context handling: Instead of blindly stuffing a context window, Cline allows precise inclusion of relevant files, folders, URLs, and even real-time diagnostic data from your workspace. It also now shows you how much of the context window you've used so far.

✅ Runtime awareness & debugging: Unlike static code assistants, Cline interacts with running systems - executing terminal commands, launching browsers, and verifying changes live. No more copy-pasting errors back and forth.

✅ Plan/act mode for control: Separate "thinking" and "doing" modes ensure careful design before execution. Perfect for complex systems that require structured decision-making.

✅ Checkpoints beyond git: Automatic state snapshots after every AI operation enable granular rollbacks - critical for experimentation without cluttering version history.

✅ Extensibility with model context protocol (MCP): Customize Cline by integrating it with internal monitoring tools, security scanning, or legacy modernization pipelines.

🎯 The bottom line

Cline isn't for casual autocompletion - it's for serious engineering. It respects existing workflows, provides visibility where it matters, and empowers teams to optimize cost, capability, and speed. I've been using it for a while and am happy to recommend it.

Check Cline out. I hope it's helpful!

Realistic ocean waves in the browser thanks to WebGPU!

Get ready to make some waves! Explore a mesmerizing demo where you can interact with realistic waves and procedurally generated ocean sounds - all thanks to the power of WebGPU & Web Audio. I've taken matsuoka_601's incredible WebGPU fluid simulations prototype and cranked up the immersion. 

Demo: https://ocean.addy.ie (code: https://lnkd.in/gzKi5dNZ, original: https://lnkd.in/g_MYyggQ)

But first, let's give credit where credit is due! Matsuoka's original graphics demos are a masterclass in pushing the boundaries of browser graphics. He generously shared the techniques behind his work, breaking down the magic to achieve stunningly realistic fluid movement, even on integrated graphics.

Check out Matsuoka's original article - it's well worth the read! https://lnkd.in/gDDdGedj

Matsuoka achieves high-performance, real-time fluid simulations in the browser using WebGPU by combining two key techniques: MLS-MPM (Moving Least Squares Material Point Method), a hybrid particle and grid-based approach, eliminates costly neighbor searches and enables efficient physics calculations, even for large particle counts.

In my version, I'm generating ocean sounds here by using white noise filtered through a low-pass filter and modulating it to create the ebb and flow of waves.

Your browser will need to support WebGPU for the demo to work (https://lnkd.in/gGCJSCGx), but the video should give you the key ideas :)

"Happiness starts with action. Move, create, give. Momentum fuels fulfillment."

If you're feeling unhappy, start with the body. Nourish it with healthy food, rest it with adequate sleep, and move it with regular exercise. A healthy body can lead to a more positive mindset and increased energy levels.

If you're feeling uninspired, start with the mind. Excite it with new experiences, expose it to different perspectives, and open it to new ideas. A stimulated mind can spark creativity and motivation.

Finally, if you're feeling unmotivated, start with the heart. Find your "why" – what truly drives and inspires you. Engage in acts of service to connect with something larger than yourself. A heart filled with purpose can reignite motivation and a sense of fulfillment.

Remember, taking care of your body, mind, and heart is a holistic approach to well-being.

"Never underestimate the power of small habits"

Small habits may seem insignificant, but they create remarkable impacts over time. These daily practices compound powerfully. 

Consider that saving just $8 daily accumulates to $3,000 yearly. Reading 20 pages each day means finishing 30 books annually. Walking 10,000 steps daily equals completing 70 marathons per year.

The secret is consistency. When you maintain a small habit long-term, results inevitably follow. Begin with modest changes and prioritize steady progress over perfection.

"What makes a software engineering team effective?"

Ever wonder what truly makes a team effective? Google's Project Aristotle, a deep dive into team dynamics, revealed a powerful truth: it's less about individual talent and more about how team members interact. And at the core of it all? Psychological safety.

The five dynamics that drive team effectiveness are:

1. Psychological Safety: Creating an environment where risks are welcomed and mistakes are seen as learning opportunities.

2. Dependability: Ensuring consistent, high-quality work delivered on time.

3. Structure and Clarity: Defining clear roles, processes, and expectations.

4. Meaning: Connecting work to a sense of purpose and personal significance.

5. Impact: Demonstrating how team efforts contribute to broader organizational goals.

While Project Aristotle's research was conducted within Google, the identified factors influencing team effectiveness could hold some relevance for teams in other contexts. By focusing on these five factors, software engineering teams can create an environment conducive to collaboration, innovation, and success

"Focus on what you can control, not what you can't"

If I could share one piece of advice to navigate not just burnout, but many of life's challenges, it would be this: Focus on what you can control.

It sounds simple, but it's profoundly powerful. We often exhaust ourselves worrying about things outside our influence. We pour energy into areas where we have little to no sway, leaving us depleted and frustrated.

Instead, what if we consciously shifted that energy inwards? What if we focused on our sphere of influence – our skills, our efforts, our reactions, our choices? 

This simple reframing can be incredibly motivating and a powerful antidote to overwhelm.

This (and many other topics) is something I discussed with Shruti Kapoor in our recent interview, and it's a principle that has truly helped me over the years. We dive into practical ways to apply this "focus on control" mindset, especially when burnout starts to creep in.

Let's shift our focus to what truly matters and what we can actually impact
