Do you remember time when context compaction meant you better start a new thread? Now I have chats that I use for weeks and don’t see any degradations after compactions.

I got Windows 11 and Windows Server 2025 running on Apple's Virtualization.framework, which officially only supports macOS and Linux. After a small pep talk with Opus 5.5, it found a hidden switch, wrote a UEFI framebuffer driver, and made this video. mustafaakin.dev/blog/windows…

The new Three Comma Club is when you use more than a billion tokens daily including weekends.

Foldable iPhone will be ideal for managing agents on the go. 🤔

New update late yesterday is DiskImageKit so we can layer image and have a base one with a bunch of other images based of it. Layering is finally coming to macOS. That's a big one!

So there is no Siri AI in the first iOS 27 Beta. What's the point of it? $AAPL again only managed to show pretty slides. A little disappointed. 😢

Top thing I want from WWDC is to expose Apps as kind of MCPs for the new Siri to use. 🤞

And of course to officially run more than two macOS VMs per host.

Smart attack vector 🤯
🚨 TL;DR: Attackers are sending fake Sentry bug alerts to projects using public Sentry DSNs. The fake alert is designed to trick AI agents into running a malicious `npx` command that looks like a Sentry profiling diagnostic. Do NOT run commands from Sentry issues/logs/alerts unless verified. These are not legitimate Sentry fix commands. The malicious package reportedly steals environment variables/secrets and sends them to advisory-tracker[.]com.

Just in time for #WWDC next week 🎉 Tart now has a new home under OpenAI organization and a new @fairsrc license attached. Next week we'll migrate release process for 3.0.0 version and will start integrating new macOS APIs. github.com/openai/tart

Immediate flashback to 2012 when I built File Watchers initially for @WebStormIDE to integrate outside tools for post processing different web stuff. Had quite a few paper cuts with VFS. 😅
Plugin authors: if you save through VFS and then hand a file path to a CLI, formatter, VCS command, or Java file API, check this. VFS may see fresh content before the disk does. If the next reader is outside VFS, flush first. blog.jetbrains.com/platform/…

Это трагедия, но я хочу чтобы все, кто гордится, что "отключился" от новостей, увидели эту цитату: "К сожалению, за новостями из России я совсем не следил. Хотя перед такой поездкой следовало бы. Я вообще не смотрю и не читаю новости с ковидного 2020 года" meduza.io/news/2026/06/02/ro…

Is it a Windows Surface Pro in a form-factor of a trash can?
Something new is coming for developers. And no, it’s not a new OS version 😅. See you at Build next week!

I still wonder how SDLC will look like in two years when everything will be AI and agent driven. Analogy I have is fully autonomous cars. Once all the cars like that you don't need speed limits and red lights. You can also imagine new geometry and patterns for roads.
