I'm no longer active on Twitter/X. Find me at Bluesky @djweitzner.bsky.social or LinkedIn. Better yet, in person. Sorry to see this once-engaging platform turned into a personal political megaphone of its owner. That's his right, but it's only 'social' in the narrowest sense.

Great thread on threats to the security of all Internet comms from misguided police demands. As usual @JuliaAngwin nails it. Her NYT piece "If law enforcement has reason to suspect us, they should get a search warrant," not leave all users open to attack. nytimes.com/2023/06/13/opini…

A luminary lineup of crypto & infosec experts including @rossjanderson @mattblaze @WhitfieldDiffie @matthew_d_green @schneierblog @djweitzner successfully argued that there was no way to keep safe a “master key” that could unlock all encryption. /3 cl.cam.ac.uk/~rja14/Papers/d…

Important thread on 230 from its main coauthor @RonWyden and advocates @CenDemTech Emma Llonso and @EFF
8 Mar 2023
Sen. @RonWyden: "Chris Cox and I wrote Section 230 with the following idea: the person who *created* the content is liable for it. Quaint idea, I know." Continues: "Its baffling that the conversation is 'Big Tech'. 230 protects everyone, and the startups need it especially."

Love these photos, @JonahSeiger! As a @SenatorLeahy alum now lucky enough to lead @CenDemTech, I couldn't be more grateful for his legacy fighting for privacy & human rights

An amazing career @SenatorLeahy: *48* years & *8 terms*. Setting the Internet policy tone on free speech, privacy, surveillance & insisting on integration of rule of law, trust in individual responsibility & innovation. @JerryBerman @DeirdreMulligan @JonahSeiger @CenDemTech
As @SenatorLeahy closes the final days of his remarkable tenure as U.S. Senator, @CenDemTech is taking a moment to thank him – for being an enduring ally in some of the most important tech policy debates of our time, since the beginning of CDT’s nearly three decade existence.👏👏

And he celebrated the victory in ACLU v Reno, declaring "Giving full-force to the First Amendment on-line is a victory for the First Amendment, for American technology, and for democracy." Let's hope we can remember this

Above all he is a model of principled, humble visionary leadership. In his farewell speech he left us with a challenge to strengthen our gov't and"rebuild a Senate defined not by sounds bites but by a believe in the strength of women and men and history." Thank you @SenatorLeahy!

This is fantastic news for @WHOSTP the @WhiteHouse and the whole country. Such a distinguished scientist and leader adding to an already fantastic team!
Today’s historic bipartisan confirmation of Dr. Arati Prabhakar as Director of @WHOSTP is a testament to her sterling track record of leadership and innovation stewardship. We’re thrilled to welcome her to OSTP and begin a bright new chapter! My statement: whitehouse.gov/ostp/news-upd…

Bravo @random_walker and @schneierblog. While there are specific cases where I think public ledgers offer unique benefits for accountability (ie work with @GoldwasserShafi et al on preventing unwarranted surveillance usenix.org/system/files/conf…) the rest is way oversold.

I agree with Bruce Schneier (@schneierblog) that blockchain has so far proven useless. Worse, it's proven a costly distraction to people and communities who are trying to solve real problems. schneier.com/blog/archives/2…

So excited to see all what this amazing team and its inspired leader, Commissioner Bedoya, will do for the country and the world!
There is a convention in D.C. that all credit goes to the principal, not their staff. We’d like to do things differently. Meet my legal staff: I could not be more proud of this group of seasoned civil servants, who have a combined 35 years of law enforcement experience.

This is a great piece of work showing the fragility of ML algorithms, how badly they can fail in dynamic healthcare settings (ie - most of them) & the need for more transparency & ongoing scrutiny of ML tools. Kudos to @YalaTweets @caseymross and the rest of the team @AIHealthMIT
