How to Run Custom Linux Images on Oracle Free Tier Bypass the Oracle free-tier limitation of running only Linux distributions provided by Oracle by sideloading a QCOW2 image to a boot volume and attaching it to a new instance.

A quick writeup on a hacky but effective method of bypassing Oracle's restrictions on #Linux distro use in their free tier. I don't trust them, but I'll happily burn some of their compute.

I have not, but maybe I don't follow. I have only seen QR used for onboarding passkeys, never authenticating with them. Untrusted devices and BLE connections seems equally strange as far as threat modeling goes, to me. Have not found it in the Bitwarden docs either. Enlighten me?

Love @bitwarden.bsky.social
I'm already a user and a fan! I use it for the few things that have passkeys in my life currently, but I still don't agree with the overarching implementation of passkeys.

I'm a user and general fan of Bitwarden -- self-hosted. It works great for me, but it still means that to use it on a "guest" device, I need to access my password manager *on that device*. The alternative being accessing my password manager on my trusted device (my phone), and transposing the data.

Passkeys are all well and good until you need to access a service on another device.

When did we sign up to be chained to a phone or endpoint with access to a service that manages passkeys?

I get the benefit, but it feels like entrapment was engineered into the workflow.

The fourth monkey has emerged. He sees no one, hears no one and speaks to no one.

End-to-End Encrypted Chat that YOU Control: Hosting XMPP (Jabber) with Prosody Start-to-finish guide for setting up a modern XMPP (Jabber) Server to facilitate E2EE chat on your own infrastructure, podman style

After a bit of a break, I've got a new homelab post in the books on #XMPP

Take control of your chat experience with #E2ee and own your data. Maybe relevant for those potentially affected by a future #chatcontrol ruling.

Check it out, let me know what you think!

It's like planting a tree. The best time to do it was yesterday.

I know it’s been said again and again, but what does it say about ChatControl that its backers keep explicitly *exempting* law enforcement and national security accounts from content scanning?

So by proxy, RC4 with Kerberos is bad.

RC4 used with Kerberos isn't the fundemental flaw we think. Yes, RC4 is deprecated, but the real issue is the key generation for AES v RC4 for cracking (Kerberoasting). With RC4 the key = password hash. With AES it is 4096 rounds of hashing of hash+username+domain. The 4096 rounds matters, a lot!

Meet Rayhunter: A New Open Source Tool from EFF to Detect Cellular Rayhunter is a new open source tool we’ve created that runs off an affordable mobile hotspot that we hope empowers everyone, regardless of technical skill, to help search out cell-site simulators

We know very little about how cell-site simulators (CSS), devices that masquerade as legitimate cell-phone towers, are being deployed in the US or globally, but with Rayhunter, we hope to change that. www.eff.org/deeplinks/2...

Kennedy guts CDC's vaccine panel of independent experts The Advisory Committee for Immunization Practices helps the agency make recommendations on who should get certain vaccines.

An outspoken vaccine conspiracy theorist just fired every last member of CDC's vaccine advisory committee.

RFK Jr. is paving the way to reshape vaccine policy based not on decades of science, but on his own unhinged fanaticism.

This is unprecedented, and unthinkably dangerous.
