@splinedrive @furt_tech Ah the Nexys Video

@furt_tech No IP cores. This was old hardware I wrote back in 2022, when I had only been working on RISC-V CPU design for about a year. It’s a fully custom implementation — TMDS encoder, video timing, framebuffer, DMA, and software running on my SoC. x.com/splinedrive/st…

@OHey_Brother A young man once asked Diogenes the madman about marriage: YM: Should I marry? D: Marriage is too soon for a young man. YM: Would you have me wait until I am old? D: Oh no, Marriage is far too late for an old man.

@dcgothcon @djdead @djdead what was the song played before the ‘velocity’ song? It was around 0100-0115am.

Also, if you want some grooves, @djdead is currently playing on the soma stage across from food court.

@0xTaylor_ Nope. Hence why I resorted to brute forcing which is relatively fast anyway.

@AstralVX Did the Bitlocker Key Extractor extension in Logic2 not work for your case?

@DerGeraetKap0tt I did mention Microsoft could use TPM param encryption, but I can make it more clearer as you suggest, thanks.

@ignasurba Yes. Recovery key allows unsealing of VMK without having PCRs in the correct state, but VMK still has to be sent from TPM to (Bitlocker running on) CPU to decrypt the volume.

@AstralVX If the computer only loads the BitLocker Recovery window, the keys are still being sent?

@BruteBee Hey, updated the post with more info: ‘Enable key protectors such as alphanumeric PIN or startup key on USB, so an attacker needs to have this additional information if the SSD is stolen; TPM has anti-hammering capabilities to prevent brute forcing these.’

@AstralVX How setting a pin, password, USB, can protrct against it?

@Bohsco @FitFounder It gets more difficult to achieve the more you train. Having ran for over a year, I don’t get the high anymore. Used to trigger after 3miles at 6mph. Now I do 5miles at 8mph and heartrate at 165bpm, no runners high. Possibly if I start increasing speed I can hit it again..

@FitFounder Running my first ultra this year. Runners high is the greatest thing on earth. Never thought I’d enjoy running until I did it consistently.

@culturaltutor Verdi’s Aida - Opera

Indeed, film has much in common with opera - it unifies music, theatre, set design, costume, and drama into a single work of art. Opera was popular entertainment in the 19th century and cinema is now; that doesn't prevent them from being - sometimes - truly great works of art.

Is cinema the greatest modern art form? Artists aren't less talented than they were in the past, it's just that they're making films instead of paintings...

@unusual_whales Get in those PUTs, here is the classic dead cat bounce.

Powell: There isn't a painless way to reduce inflation.

@unusual_whales Go 100-150 hike. These PUTs need to print baby. Got some CALLs to hedge. I’m about 3:1 Puts/Calls expiring 09/23. Give me volatility and let’s wreck this market. To hell with my 401k…

@aahmad097 Looks like the stock market, crypto market, and economy. Everything is coupled.

@NTDEV_ Is this inside jokes like those found in XP/7 leaked source code. “Test these dicks”

@dwizzzleMSFT @NSAGov SecureBoot is designed to ensure the firmware running during preboot is signed and trusted by the OEM vendor. When OS successfully loads it trusts the firmware to have loaded it via a secure chain of components. SecureBoot by design can be disabled in BIOS via physical presence.

We need to talk about how this thread is inaccurate. Thx to Kev for clarifying. @NSAGov has a great doc on secure boot. nsa.gov/news-features/… Secure boot is DESIGNED to be DISABLED with Physical presence (boot menu, BIOS) happy to answer questions.
