Off to #RealWorldCrypto to present my work on online (streaming) and random-access encryption!

Taipei, here I come!

None at all.

Smooth, safe, interfaces. If they need to think about the tool at all it means there is room for improvement.

It's only a man trap if it's from the Isle of Mann. Otherwise it's just a sparkling vestibule.

Cryptography Engineering Has An Intrinsic Duty ofΒ Care To understand my point, I need to first explain three different cryptography attack papers / blog posts. I promise this won't be boring. Three Little Dislcosures Misuse-Prone Ciphers For All In a blog post titled Carelessness versus craftsmanship in cryptography, cryptography analyst and Queer in Cryptography emcee Opal Wright delves into the misuse-prone and side-channel-riddled JavaScript and Python implementations of the AES block cipher.

Cryptography engineering has an intrinsic duty of care.

Yeah. Reads fine to me (programmer/cryptographer).

I think that along with their beliefs in eugenics and pre-germ theory, they've also brought back phrenology.

Honestly, I'd support prescriptive phrenology in their cases.

The greatest offense to being presented with LLM generated text isn't just them thinking it coul be helpful to me, it's specifically that they think I'd be better off from *them* being the ones doing it despite their lack of context and lack knowledge about my process

One nice thing about Instagram as a host for my short form vidya is you don't need to post every day to maintain momentum. That was really wearing me down on Tiktok.

I'm convinced AI is our generation's radium - a discovery with genuinely useful applications in specific, controlled circumstances that we stupidly put in everything from kid's toys to toothpaste until we realised the harm far too late where future generations will ask if we were out of our minds.

He went inside to change his boots, dropping them off by the front door. As he was grabbing his sneakers from the jumbled pile of shoes, someone turned on the TV in the living room. It was an old tube
set that didn't work so great, so there were small bursts of static between each channel flip. As Gabe tied his shoes he heard a burst of what sounded like some morning show (which was weird, neither Agnes or
John watched those, and he was about to use the fact that somebody was watching TV to slip out
unnoticed when he heard his name.
"Gabriel-"
Weird. He wondered what was on that channel. Then the channel flipped again.
"we need"
Someone must've been looking for something specific. John wasn't usually this impatient. Nor was
anyone else who watched TV.
"to talk."
A slow chill ran down his spine. Hearing those words strung together from patchwork was disquieting,
but it was probably coincidence. He took two steps back. The pattern of flipping channels repeated, and
this time Gabe couldn't ignore the string of words coming from different voices.
"Gabriel"
"-we"
"need"
"to"

NEW: This isn't about "training." The two agents who murdered Alex Pretti - Jesus Ochoa and Raymundo Gutierrez - have been with Border Patrol for 8 and 12 years respectively. You can't reform CBP. Abolish ICE/CBP. www.propublica.org/article/alex...

Abolish ICE and fire all agents is the moderate position.

This judge does the thing quoting the Declaration of Independence at the Trump regime then adds for good measure: "Observing human behavior confirms that for some among us, the perfidious lust for unbridled power & the imposition of cruelty in its quest know no bounds & are bereft of human decency."

I wonder if there’s good resources for protest beginners about how to tell the difference between higher and lower risk protests.

If you’ve been doing it for a long time you can just kinda feel it out, but for those who haven’t….

This is a very clever tactic designed to make the speaker sound empathetic and compassionate, but if you actually pay attention to what he’s saying the substance is no less horrifying.

β€œI told you to stop resisting. If you keep resisting we will start killing you.”

It’s abused language 101.

If you work at DHS and know the identities of the CBP officers that murdered Alex Pretti, my Signal contact info is in my bio. I’ll keep you anonymous.
