Proton Mail Helped FBI Unmask Anonymous ‘Stop Cop City’ Protester A court record reviewed by 404 Media shows privacy-focused email provider Proton Mail handed over payment data related to a Stop Cop City email account to the Swiss government, which handed it to the FBI.

It's both disingenuous to celebrate Proton (who are a business making money in a friendly nation) as bulletproof, and to compare them to Google, who make money by mining your email content. Understand your threat model and message accordingly. www.404media.co/proton-mail-h...

I think a skillset the maga movement has always had is the ability to co-opt (and hollow out) the language of the left. It makes sense to me that those who are now “deconstructing” are borrowing a framework the token liberal of their community has talked about in whatever discourse they may have.

This gives me hope. I throw my application at CS whenever I see a role I know I’d be good for and lost count how many times I’ve been rejected 😅

I'm not sure if a long weekend in snowy NYC, bouncing between some favorite restaurants and seeing as many shows as we can schedule helps at all with depression.

I'm willing to give it a shot, for science. Will report back sometime next week!

Job hunt continues. A recruiter pinged me and let me know about a possible position he’s trying to get me an interview for. I got the preliminary “partial lapse of funding” emails in case we shut down at the end of this week. So my anxiety is high and hoping I land something soon!

Posting as a proof of life l! Lots of ups and downs 😅

Our power was restored Tuesday night and am thankful for it. Still 100k people without power in Nashville and getting around town is dicey. It’s obvious NES had done zero contingency planning ahead of this winter 😡

The only real way I have marked the passage of time this week is getting closer to the Stranger Things finale and college football games to cosplay for.

We didn’t have any family stuff until later in the evening and so we took a spur of the moment day trip to Metropolis, IL, the official hometown of Superman.

It’s definitely a drive through town, but I highly recommend stopping by if you’re up for some superhero whimsy.

Merry Christmas, y’all!

If you happen to be looking for bad redactions in a large set of data files today for some reason, there's an open source tool for that.

Looking back at 2025 Journalists are working harder than ever to protect their sources. SecureDrop has never been more important

Journalists are increasingly relying on insider sources, and protecting those sources is more important than ever.

Here's how SecureDrop is rising to the challenge, safeguarding whistleblowers’ anonymity against ever-evolving threats.

Afraid of retaliation and in an increasingly volatile job market, afraid to leave too. It’s quite a bind.

With the 60 minutes leak, the many recent Epstein releases, etc., I think we are seeing the future of government accountability under authoritarianism:

Leaks, hacks, data dumps, releases of big document caches.

Journalists and the public will have to learn how to digest this stuff. 🧵

This was for a senior security engineer position and after that I declared my entire job search completely baked.

I was recently asked “tell me about a CVE that’s given you trouble this year”. My response was how a couple of low severity CVEs had been exploited together to try to gain access to a cloud service and how our security controls prevented the breach.

His response: “I only asked you about one CVE” 🫠

The top strand of lights on our fake Christmas tree stopped lighting up and I feel like witnessing our tree slowly go out like this is appropriate for 2025.

Companies Are Blaming AI for Layoffs. The Real Reason Will Piss You Off. 180,000 tech workers lost their jobs in 2025. Companies say it’s because of AI. Oxford researchers call BS.

Companies aren't firing workers in staggering numbers because AI can do that work instead. They're firing workers because they lost their bet on AI against the House.

Kingsbury's "Matthew as Story" is a little bit dated, but still quite useful. I'd also recommend Garland's "Reading Matthew: A Literary and Theological Commentary" for anyone who hasn't come across it yet.
