If you're a Google Workspace customer and you have already opted out of gemini for your workspace during the beta, you will need to do so again for GA. Coming by end of this month (April 2025).
Screenshot with the following text. Dear administrator, We’re writing to let you know that the Google Workspace apps (formerly Google Workspace extensions) setting in the Gemini app will transition from beta to general availability (GA) by the end of April 2025. This change will enable the Gemini app to interact with Calendar, Docs, Drive, Gmail, Keep, and Tasks, providing more context to your prompts. We’ve provided additional information below about this change. What this means for your organization Key Change: When the Workspace apps setting becomes generally available, it will be turned “ON” by default. This will override the current Workspace apps Beta setting.

Say what you will about Apple vs other laptop manufacturers, but I just upgraded to 2x8TB NVMe drives for $918.

How much does upgrading to 16TB cost with a MacBook? $2,200 for 8TB.

More than double the price for half the storage.

Ephemeral port usage?! This must be an advanced adversary, probably a nation state.

I don't want to scare y'all, but I just checked the @greynoise.io sensor logs and found over 1000 sessions in the last hour that used this sophisticated technique (ie, attempted to download malware over ephemeral ports)!!
A news story from today: Headline: Threat Actors Using Ephemeral Port 60102 for Covert Malware Communications Recent cybersecurity investigations have uncovered a sophisticated technique employed by threat actors to evade detection during malware distribution. Attackers are leveraging ephemeral port 60102, typically reserved for temporary communications, as a service port for covert malware transmission. This approach bypasses traditional monitoring systems, which often focus on scanning standard service ports such as 80 or 443.

A level of Hell that could only be found in DOOM. Bravo.

I made a Doom source port that runs within a PDF file.

PDFs support Javascript, so Emscripten is used to compile Doom to asm.js, which is then run within the PDF engine. Input/output is done by manipulating text input fields.

Louder for the people in the back!

Seriously, this turns "we've always done it this way" into "here's why we do it this way."

It’s too common to not have a record of why decisions were made. Getting the logic documented can help justify change or remind future decision makers about anticipated challenges that might otherwise be forgotten with time.

I know posts about the prior platform aren't the only focus here, but I finally killed my phone's birdie shortcut and added Bluesky instead.

Too many posts from a certain owner plastered over everything.
