MotionKit Figma Motion: import, sync, and push native animation (yes, even baked physics)
Figma shipped native Motion. A real animation timeline, right inside the file. When that landed, a lot of people emailed me some version of the same question: "is MotionKit dead now?" Fair question. My honest first reaction was a quiet "...maybe." But the more I used native Motion, the clearer it got — it's genuinely good, and it's not trying to be everything. No physics. No frame-by-frame. No Lottie export. No morphing. So the move was never to compete with it. The move was to bridge to it — let the two tools hand work back and forth, and let MotionKit be the power layer that does the stuff native Motion can't. So that's what this update is. A two-way bridge between MotionKit and Figma's native Motion. Here's everything it does, and exactly how to use it. The short version Four moves, one little control in the header: Import native Motion into MotionKit as real, editable keyframes Live sync (read-only by default) so changes in Figma Motion flow into MotionKit as you work Link for export so your native Motion renders inside a Lottie without duplicating anything Push MotionKit keyframes back into native Motion — including motion you baked from the physics engine And the headline trick: bake a real physics drop in MotionKit, then push it into Figma Motion as native keyframes. Native Motion has no physics engine. Now it kind of does. First, find the bridge Look at the top-right of the toolbar, next to the Pro star. There's a small badge: the MotionKit diamond, an arrow, and the Figma logo . That little arrow is the status. You don't have to open anything to read it: faint dotted line → not connected arrow pointing into MotionKit → reading from Figma, live, read-only arrows on both ends → two-way, MotionKit also writes back If there's native Motion sitting on the current frame but you haven't connected, you'll see a small purple dot on the Figma side — that's "hey, there's something here to import." Click the badge to open the bridge. That's the whole mental model. Dire

Even Figma isn't sure about its own design tokens
The whole industry seems to have agreed on a standard for design tokens. The shift it sets up is still on its way. Design tokens are not new. The term was coined in 2014, at Salesforce, by Jina Anne and Jon Levine. 1 By 2017, Amazon had open-sourced Style Dictionary and the idea had spread well past Salesforce. We have been shipping design tokens for over a decade. What we never did, in all that time, was agree on a format. Every tool and every team rolled its own shape. There was never one neutral way to write a token down, its value and its meaning, so that any other tool could read it. Have you heard of DTCG? I hadn't, until recently. It is the Design Tokens Community Group, a W3C effort to finally settle that format. 2 The repo is quiet, but that is because the spec reached its first stable version in late 2025, not because anyone walked away. The quiet is a thing being finished, not abandoned. The list of who is backing it is not quiet at all. Adobe. Google. Microsoft. Meta. Amazon. Shopify. Salesforce. Sony. Pinterest. The New York Times. Disney. Framer. Penpot. Figma. Plus a dozen more. 2 That is not a side project. That is most of the industry quietly agreeing on something. One of those names, Figma , is the reason for the title of this piece. We will get to it, because the irony is the whole point. Here is my bet, and I will say up front that it is a bet. I think a storm is coming for design tooling. You do not have to believe me about the storm, because the bet does not depend on it. If you are wiring your tokens straight into one vendor's format, you are exposed. Anchor them to the open standard instead and you are not. The downside is lopsided. If I am wrong, you have lost almost nothing. If I am even half right, everyone hard-coded to a single tool is facing a rewrite. The format is young and already fragmenting. That is the point. The obvious objection is that the standard is too new to bet on, and already splintering. It is splintering. Google's DESIG

Hyperpb Parser Matches Generated Code Speed
This week's tooling news splits cleanly between performance and compliance: a Go Protobuf parser that closes the gap between reflection and generated code, and a GitLab update that finally makes air-gapped AI deployments practical. Layered in are a forced AWS migration, a cost-pressure move in reasoning model pricing, and an Elasticsearch alternative picking up serious enterprise backing. Here's what's worth your attention. hyperpb Dynamic Parser Matches Generated Code Speed hyperpb is a runtime-compiled Protobuf parser for Go. You feed it a schema at startup, it runs an optimization pass, and the result is a compiled message type you can reuse across requests. Benchmarks show 10x faster parsing than dynamicpb and roughly 3x faster than hand-written generated code. The implication for generic Protobuf services—brokers, validators, schema registries—is significant. If you're doing broker-side validation today with dynamicpb , you're likely throttling throughput or skipping validation under load. hyperpb removes that tradeoff. The catch is that compiled types require caching (the optimization pass is slow and should not run per-request) and field access remains reflection-only—you're not getting struct field ergonomics. Verdict: Ship. If your validation pipeline is hitting dynamicpb throughput limits, this is a drop-in replacement for the hot path. Cache your compiled message types at initialization, and profile field access patterns before assuming it fits your read-heavy workloads. Quickwit Joins Datadog, Relicenses to Apache 2.0 Quickwit, the Rust-based petabyte-scale log search engine, has been acquired by Datadog and relicensed from AGPL to Apache 2.0.

NeMo out, GGUF in: how parakeet.cpp ports NVIDIA ASR to C++
NVIDIA's Parakeet speech models used to mean a Python stack: NeMo, PyTorch, and a GPU you kept warm. A new C++ port collapses that to one binary and one file. From NeMo to GGUF: What the Port Covers parakeet.cpp is a C++17 inference port that runs NVIDIA's Parakeet automatic speech recognition (ASR) models on the ggml tensor library — the same engine behind whisper.cpp and llama.cpp — with no Python, no NeMo, and no ONNX at inference time. The project is maintained by Ettore Di Giacinto (@mudler), author of LocalAI, and its first tagged release, v0.1.0, landed on May 30, 2026 . The code is MIT-licensed; the model weights keep their original NVIDIA Parakeet licenses. This is a community project, not an official NVIDIA release. The port covers the offline Parakeet families — CTC, RNNT, TDT and hybrid TDT-CTC — in 110M, 0.6B and 1.1B sizes, plus a streaming 120M model with end-of-utterance detection . Two checkpoints anchor most use: parakeet-tdt-0.6b-v2 , the English default that reports 6.05% average WER on the Hugging Face Open ASR Leaderboard and was released 05/01/2025 , and parakeet-tdt-0.6b-v3 , which extends the same 600M FastConformer-TDT architecture to 25 European languages with automatic language detection, released 08/14/2025 . Inference runs on CPU, CUDA, HIP (AMD ROCm), Vulkan and Metal (Apple Silicon) — the same ggml backend matrix as whisper.cpp and llama.cpp — so deployment reduces to one binary plus one GGUF file . The hard part was mapping Parakeet's RNNT/TDT decoders onto a static-graph tensor library. An earlier work-in-progress port surfaced on Hacker News in mid-2025, where the author flagged how far there was to go: "The GGML build is roughly 1000x slower than the MLX Python version" — jason-ni, reporting an early Parakeet-on-ggml experiment (source: Hacker News, 2025 ; see also the jason-ni port ). The mudler release is the matured answer to that decoder-on-static-graph problem, and as of June 2026 Parakeet is not yet merged into mainline whis

How to Choose the Right Color Palette for UI/UX Design
A beautiful interface isn't created by random colors. The right color palette can increase usability, improve brand recognition, and guide users toward important actions. Here's a simple process I follow when designing products: ✅ 1. Start with Your Brand Personality Ask yourself: • Professional or playful? • Premium or affordable? • Modern or traditional? Examples: 🔵 Blue = Trust, security, professionalism 🟢 Green = Growth, health, sustainability 🟣 Purple = Creativity, innovation 🔴 Red = Energy, urgency, excitement Your primary color should reflect your brand's personality. ━━━━━━━━━━━━━━ ✅ 2. Use the 60-30-10 Rule A balanced interface often follows: • 60% Primary Background Color • 30% Secondary Color • 10% Accent Color This creates visual harmony and prevents color overload. ━━━━━━━━━━━━━━ ✅ 3. Limit Your Palette Many beginners use too many colors. A professional UI usually needs: • 1 Primary Color • 1 Secondary Color • 1 Accent Color • Neutral Colors (White, Gray, Black) Less is often more. ━━━━━━━━━━━━━━ ✅ 4. Think About Accessibility Your design should work for everyone. Check: ✔ Text contrast ✔ Button visibility ✔ Readability on mobile screens If users struggle to read content, even the most beautiful design fails. ━━━━━━━━━━━━━━ ✅ 5. Create a Consistent Color System Instead of random shades: Primary: • 50 • 100 • 200 • 300 • 400 • 500 Secondary: • 50 • 100 • 200 • 300 • 400 • 500 This makes scaling your product much easier. ━━━━━━━━━━━━━━ ✅ 6. Analyze Successful Products Study platforms like: • Airbnb • Spotify • Stripe • Notion Notice how they use color intentionally to guide user attention. ━━━━━━━━━━━━━━ 💡 Quick Formula Primary Color → Brand Identity Secondary Color → Support Content Accent Color → Call-To-Action Buttons Neutral Colors → Layout & Typography Good UI isn't about using more colors. It's about using the right colors in the right places. What's your favorite color palette for modern web applications? UIUX #UIDesign #UXDesign #WebDesign #Produc

Send personalized emails from a sheet in Gmail
Originally written for bulldo.gs — republished here with the canonical link pointing home. I have a spreadsheet of names and email addresses and I want to send each person a personalized message from my Gmail account without copy-pasting or using a paid tool. // Mail merge: Sheet cols A=Name, B=Email, C=Sent // Run from Apps Script; authorize Gmail + Sheets scopes function sendMerge () { var sheet = SpreadsheetApp . getActiveSheet (); var rows = sheet . getDataRange (). getValues (); var quota = MailApp . getRemainingDailyQuota (); var sent = 0 ; for ( var i = 1 ; i < rows . length ; i ++ ) { if ( rows [ i ][ 2 ] === ' Sent ' ) continue ; if ( sent >= quota ) { Logger . log ( ' Quota reached at row ' + ( i + 1 )); break ; } var name = rows [ i ][ 0 ]; var email = rows [ i ][ 1 ]; var subject = ' Hey ' + name + ' , here is your update ' ; var body = ' Hi ' + name + ' , \n\n Your personalized content goes here. \n\n Thanks ' ; MailApp . sendEmail ( email , subject , body ); sheet . getRange ( i + 1 , 3 ). setValue ( ' Sent ' ); sent ++ ; } } Set up your sheet and open the script editor Put names in column A, email addresses in column B, and leave column C blank — the script writes 'Sent' there as it goes. Header row in row 1 is assumed; the loop starts at index 1 (row 2) to skip it. Open the script editor from Extensions > Apps Script, paste the function, and save. The first time you run sendMerge() Google will ask you to authorize two scopes: Sheets (read/write the active spreadsheet) and Gmail (send mail on your behalf). Both are required. If you only see a Sheets prompt, delete the file and re-paste — a cached partial authorization sometimes skips the Gmail scope on older script files. Why the Sent column is the whole point Consumer Google accounts cap at roughly 100 outgoing recipients per 24-hour rolling window via MailApp. If your list has 200 rows and you run the script at 11 pm, it will send 100 and log 'Quota reached at row 101'. Without the Sent check, a sec

Why AI Keeps Generating the Wrong Design Tokens and How I Fixed It with Figma's API
AI design system output is approximate by default. Wrong border radii, raw hex values, inconsistent tokens across 60 components. The fix isn't better prompts. Here's the structural change that made it exact using Figma's REST API. The fourth time I manually corrected the same border radius mistake in an AI-generated component, I stopped and asked why this kept happening. Not "what prompt would fix this?" The deeper question: why does every AI tool I tried get the structure right and the values wrong? The button was correct. The variants were there. The layout matched the Figma spec. But borderRadius: 8 when it should be borderRadius: '8px' . A spacing gap of 8 when the spec said 6 . The color #3B82F6 sitting in the file where semantic.button.primary should be. None of it wrong in a way that breaks the build. All of it wrong in a way that breaks the design system. After hitting this wall enough times, I realized the problem wasn't the AI. It was the question I was asking it. Why AI keeps generating the wrong Figma design tokens When you give an AI tool a Figma screenshot and ask it to produce a component, it does something reasonable: it interprets what it sees. The structure, the layout, the hierarchy - it gets most of that right. What it cannot get right is the token mapping. The AI doesn't know your semantic token file. It doesn't know that #3B82F6 maps to semantic.button.primary in your codebase. It doesn't know that your MUI setup multiplies numeric border radii by 4, which means borderRadius: 8 renders at 32px instead of 8px . So it approximates. Here's what that looks like in practice: What AI produces What the spec requires Why it's wrong borderRadius: 8 borderRadius: '8px' MUI multiplies numeric values by 4 gap: 8 gap: 6 Spacing value not extracted from Figma color: '#3B82F6' semantic.button.primary Raw hex instead of semantic token fontSize: 14 variant="MD_Medium" Typography token not resolved Across one component, these deviations are small.

Turning Kiro Into a Leadership Coach With Meeting Transcripts
As an Engineering Manager in a Platform team, I manage 10 engineers. I'm hiring more. I run weekly 1:1s, facilitate technical decision meetings, screen candidates, moderate retrospectives, and still need to keep up with the delivery of a platform spanning dozens of AWS accounts. Besides the lack of time to focus on technical problems, the technical part is not even the real challenge. The less obvious problem becoming an Engineering Manager is: the skills you need as an engineering manager are fundamentally different from those that made you a great engineer , and there's no compiler or unit test to tell you when you're doing them wrong. The feedback loop is absent or very slow (and when you realise that, your team has already gone silent or become dependent on you because you are the main input and the main bottleneck). Skills That Don't Come From Code As a senior or staff engineer, you develop communication skills gradually. You present ideas, challenge others respectfully, summarise outcomes, and identify owners. You participate in technical deep dives and put candidates at ease while probing technical depth. These are valuable skills, and a good IC develops them over the years. But unless you start behaving like a brilliant jerk , they're secondary - your technical depth is still what defines you. But as an EM, the game changes. You're not "the smartest person in the room" anymore, and increasingly, you shouldn't be. You still have a broad context from all those alignment meetings and roadmap syncs, but you lose contact with the codebase week by week. If your organisation has principals or staff engineers, you're not even close technically anymore. Your job is to give direction, create space for others to solve problems, and facilitate decisions, not to be the one with the answer. This is hard. Especially when you used to be the one with the answer. The urge to jump in doesn't disappear just because your title changed. And interviewing? Facilitation? Giving feed
