@RetroTechChris 2.5 was pretty rough especially on x86 with a very foreign userland compared to what most people are used to with Linux. Solaris x86 wasn't usable IMO until Solaris 10.

Breaking News: Anthropic surpassed OpenAI as the world’s most valuable A.I. start-up, with a valuation of $900 billion. https://t.co/ERFCrHtkZ6

@QuinnyPig Never could’ve seen this one coming. Something, something about incentives creating bad behavior.

NEW: Amazon has reportedly scrapped its internal AI leaderboard as costs soared, with a senior executive telling staff: “don’t use AI just for the sake of using AI.”

New in Claude Code (research preview): dynamic workflows.

Claude writes an orchestration script on the fly, then spins up a large fleet of coordinated subagents in parallel to take on your most complex tasks.

Use the word "workflow" in a prompt to get started.

Opus 4.8 is live in Claude Code today.

A few things worth knowing: 🧵

Looks like IBKR has a hosted MCP server now for Claude, ChatGPT, etc., but no multi-account support. Bummer.

@BadalK99277 Logitech is ugly, and I prefer the aesthetics of the Magic Mouse. Logitech generally feels better and obviously works better if you're switching between macOS and other platforms. Saying this as someone that owns and switches between both fairly regularly.

[Derek Lewis @dlewis]

@coderaw_ Solution: buy both. I have 2 Macbooks for Apple stuff and a Thinkpad for Windows/Linux stuff. No need to choose just one. It is OK to own multiple platforms.

@mweinbach Aside from certain sovereign use cases where the model has to be in the 4 walls, the economics don't work out & you're going to pay a significant amount of capital to run an inferior model relative to SOTA.

@ibuildthecloud Mutter on 26.04 does not support tiled 5K and above displays without horrible tearing. https://t.co/2KBYCABNp8

[Derek Lewis @dlewis]

I'll give Ubuntu another try again when this PR is merged, otherwise the tearing on my Apple Studio Display is horrendous: https://t.co/2KBYCABNp8

[Derek Lewis @dlewis]

Tried Ubuntu on my Thinkpad X1 Carbon again with the 26.04 release, and Linux on the desktop still leaves a lot to be desired. Wayland should be better, but somehow synchronized tiling on a 5K display doesn't work. Back to Windows 11+WSL for non-Mac stuff.

[Derek Lewis @dlewis]

Maybe I missed something, but just found out that Windows 11 now has full support for the Apple Studio display, including sound & camera. I don't remember that working in the past?

The release candidate for MCP 2026-07-28 is out. The protocol is now stateless: no handshake, no session id, any request can hit any server instance. Plus extensions as first-class (MCP Apps, Tasks), auth hardening, and a proper deprecation policy so we don't have to do this again.

Switched to Kagi and so far enjoying the experience. Using it with Safari isn't as bad as I thought it was going to be. Apple should allow configurable default search engines or at least add Kagi to the choice.

@billycoore I remember seeing these as a kid in 1995 at the local Office Depot. The tower model ended up being our first PC.

[Derek Lewis @dlewis]

Learned my lesson once again buying "new" laptops on Amazon. Wanted to purchase another Lenovo X1 Carbon since Lenovo has been OOS as of late and this is what is being represented by the seller as "new". Seller wasn't bright enough to wipe the BIOS logs, which show some use after the 5/25 manufacturing date. The laptop had an "upgraded" Samsung 2TB consumer SSD, so someone removed the enterprise OPAL 1TB drive the SKU shipped with. Promptly returned to the seller and the Amex chargeback is ready to go.

Since the IBKR apps leave something to be desired, I’m having some fun today with C++ and SDL3 writing a Bloomberg-like front-end with the Interactive Brokers TWS API.
