One bug that held us back was “don’t correct while you’re scrolling.” It was a timestamp guard, and our own programmatic scrolls refreshed it. Toggle the sidebar, and the diff pane changes width. Wrapped lines reflow, and the surface emits a small scroll as it settles. The guard read that as your input and skipped the correction meant to keep your place. The file you were reading drifted off screen.

Two years ago, SpaceX did something straight out of science fiction: catching a skyscraper-sized rocket booster out of the sky with giant chopsticks On October 13, 2024, Super Heavy returned to Starbase and was caught by the launch tower on the very FIRST attempt Since then, SpaceX has successfully caught Super Heavy two more times and even reflown a previously caught booster I've watched these catches so many times, and I still never get bored. It's unlike anything ever done before It's just pure engineering magic....

🚨🇺🇸🇮🇷 BREAKING: The 60-day US-Iran deadline just ran out with no deal. The Islamabad MoU gave both sides until today to lock in a final agreement. Nothing got signed. They can't even agree on what the expiry means. Washington calls it the end of a ceasefire. Tehran says the MoU ended the war, so there was never a truce to extend. Hormuz is the real fight. Iran reclosed it, the US reinstated its blockade, and Trump's now floating declaring the strait U.S. territory. Everything points to more escalation. But six months in, both sides are exhausted enough that neither might have the appetite. Source: Al Jazeera / Writer: Daniyal

libghostty for WebAssembly got a lot of love recently and is now very, very, very good. I spent the day building harnesses and comparing to xterm.js and here are the results: faster at IO, faster at reflow, faster at rendering. Like, a lot a lot faster. We now provide pre-built `ghostty-vt.wasm` files in our GitHub releases. These are the fastest, most optimized builds that are compatible with every major browser going back a number of years. Before going over setups, I want to say that xterm.js is very good software. It is a relatively modern terminal, the maintainers are very nice, it's done incredible work for the web terminal ecosystem. I have nothing against them, but I'm in the business of making super fucking fast terminal emulators. Let me explain the setup in every case: IO throughput: This is an apples-to-apples comparison of `ghostty_terminal_vt_write` vs xterm's `Terminal.write(Uint8Array)` timed from first write to final completion callback. This is testing how fast a terminal emulator can process input and update internal state. Nothing else. Units are in MB/s processed. Note for graphemes: Ghostty has grapheme processing enabled and xterm.js does not (requires an addon). So, this shows how Ghostty does better despite having that cost. Column reflow throughput: Compares `ghostty_terminal_resize` to xterm's `Terminal.resize` with identical terminal states (same content, same size, same scrollback). The "dance" is rapid bigger/smaller resize of matching column widths, forcing text reflow. Units are in resizes/second. Render speeds: These test use the identical xterm.js WebGL renderer for both Ghostty and xterm.js. Since the renderer is identical, we can focus on how long it takes to prepare the inputs to the renderer (build the render state) and assert we get the same output byte-for-byte (since its the same renderer!). This is the truest way to measure these two because libghostty-vt itself does not provide a renderer, its about how long it takes to go from terminal state to render-ready. Full render: This tests a fresh renderer with nothing previously rendered. Units are in updates/second. Incremental render: This tests having prior state and only rendering specific changes such as adding scrollback, moving the viewport, moving the cursor. Units are in updates/second. This is using the latest released version of xterm in every case compared to the HEAD libghostty (since we haven't tagged a release, exact commit d760ee96e54657416eb427b793c7e839f003df7d).

Sharing some more UI previews for Superlogical, this time the "tab peek." If you three-finger swipe down, you can "peek" at the other session tabs. These are live-updating, metal-rendered previews including splits. If you keep dragging, you enter a "mission control" style mode. This is one of those UI patterns that once you get used to, you mindlessly find yourself doing it ALL THE TIME. It's a great way to quickly take a look at everything thats going on. You aren't reading the mini text of course, but the shape of it tells you a lot about where things are. The peek pushes the terminal down off screen, it doesn't resize it, so it doesn't force any weird reflow or anything either. There's a lot more to talk about, especially about how this interacts with how we expose what needs attention so you can easily find the terminals/sessions/etc. that require your attention. Of course, you'll be able to drive this with the keyboard too. :) As always, a disclaimer: this is all early work subject to change, just trying to share some of what we're building in public. A lot of the UI experiential design is @almonk so follow him for more updates too!

Another *giant* Grok Build release from @SpaceXAI 🔥 Version 0.2.121 (2026-08-05) is live. Here are the standout changes: Features - Dashboard rows now display a short summary of what the agent did on the previous turn - Extensions modal groups items alphabetically with collapsible Skills sections - Parent agent gets reminded to keep working when a subagent runs in the background - Clients can reattach to a running session without replaying the full transcript and can close sessions explicitly - Grok no longer asks which project directory to use when launched from home or other non-project folders - /feedback opens a dedicated report box instead of dropping into prompt mode - Auto theme detection works over SSH and inside tmux - Voice and Finance tool cards render with icons and localized labels - Markdown tables reflow inside cells on narrow panes instead of clipping Bug fixes include better handling of large MCP image outputs, reliable session resumes after remote restores, correct default branch detection, and smoother cancel behavior so background tasks stop cleanly.

🚨 NEW GROK BUILD UPDATE 🚨 v0.2.121 — 2026-08-05 Features: • Dashboard rows now show a short summary of what the agent did in the previous turn. • The Extensions modal now shows items grouped and sorted alphabetically with collapsible sections for Skills. • When a subagent runs in the background the parent agent is now reminded to keep working on the original task. • Clients can now reattach to a running session without replaying the transcript and explicitly close sessions. • Grok no longer asks which project directory to use when launched from your home folder or other non-project directories. • /feedback now opens a dedicated report box instead of entering prompt mode. • Auto theme detection now works over SSH and inside tmux sessions. • Voice and Finance tool cards are now rendered with icons and localized labels. • Markdown tables now reflow inside cells on narrow panes instead of clipping the right border. • Permission prompts now show the complete script clearly instead of dimmed fragments. • Long bash commands in permission prompts can now be expanded with Ctrl-F.
