me, on getting my 2E0: OMG I'm going to recrystal these pagers for 144.65!
me, today: Younger Me was an idiot. 144.8 would have been a better pick, that's APRS... 144.65 is a RAYNET emcomms frequency.

Net outcome of this is, I'm probably going to have to get some new crystals made.

9 PM EST @SummerC0n late night hax will be airing the classic "Sneakers" with @BishopFox providing the late night snax!

Remember: "MY VOICE IS MY PASSWORD"

When I entered the museum, the volunteer at the door greeted me with, “You must be Will!” (I was not.) Whew.

It’s an interesting little museum but a bit nerve wracking driving there for the first time.

Some of my favorite artifacts included a hidden burst transmitter, the black box randomizer, and the US version of the BOMBE Enigma decryption machine.

Fascinating. Leaked LLM prompt instructions from most of the chat sites.

@ramsey https://github.com/elder-plinius/CL4R1T4S Many if not all LLMs are secretly fed a "system prompt" that is effectively prepended you every prompt the user sends it. These are the "previous instructions" that the phrase you mention attempts to circumvent. A simple attack like that is no longer effective, but researchers continually improve the methods to get unrestricted output from LLMs (dangerous information, secret info from other users, etc.)

⚠️ Mastodon and Misskey will never ask you to verify your ID.

This is a scam attempting to collect personal information and, in some cases, hijack accounts by tricking you into clicking malicious links.

⚠️ However, Mastodon and Misskey do offer an option in your account settings to enable two-step verification for logins.

For your own security and to help prevent brute-force attacks, it’s strongly recommended that you enable this feature on your account.
