Ever wonder how 2000 DDR5 memory modules are shipped? Apparently in a cardboard box taped to a wooden pallet. Shipping labels blurred for security reasons with the help of @asklumo

It's truly frightening how fast temperatures can rise in a high power datacenter in the event of a total cooling failure. The baseline is 30C and the peak is 60C. It's a 30C climb in about 20 minutes.

Deep apologies for everyone impacted by the @ProtonPrivacy outage earlier tonight. We had an unprecedented total cooling failure at our Frankfurt datacenter which unfortunately required more time consuming manual recovery.

This meant we had to prioritize either restoring cooling or saving the extremely expensive hardware by powering off everything. This particular failure mode was actually known to us, but mitigations were not prioritized because the scenario was judged to be extremely unlikely.

Cooling systems are highly redundant for obvious reasons, but unfortunately Murphy's law happened. We are now working on implementing changes to ensure this type of incident cannot reoccur. Thanks again for everyone's patience and understanding.

In a few years, Europe will be governed by right wing governments, and they will read your encrypted messages, prevent you from posting and reading ideas they disagree with and even jail you for wrongthink, and the current governments create the laws making that possible

This is what treason looks like. @EP_President Metsola just sold out the privacy of European citizens to her Big Tech paymasters, despite a majority of parliament voting no. #chatcontrol

Falls sich jemand fragt, wie Parlamentspräsidentin Metsola auf die fixe Idee gekommen sein könnte, die Chatkontrolle für heute, 12 Uhr, (rechtswidrig) noch einmal auf die Tagesordnung zu setzen - hier ein paar Schnappschüsse von ihrer Kalifornienreise Ende Mai...

This is insane. In response to Project 2025, the issue the Dems decided to run on with Project 2029 is requiring ID to use the internet. This is literally what Big Tech wants, as the collector of all those IDs. This is not going to be a winning platform. semafor.com/article/06/28/20…

Exclusive: Democrats’ ‘Project 2029’ goes after tech companies with online safety plan

The liberal counterweight to conservatives’ Project 2025 is rolling out a series of policies to set the stage for an already crowded field of 2028 presidential hopefuls.

Let me get this straight. PM Starmer, who is about to be ousted due to Epstein stuff, decides for his legacy, he must "protect the children" by requiring ID to use the internet in the UK? Let's just be clear, there's no such thing as age verification for children only.

As the AI boom is minting billionaires by the day and the first trillionaires are now coming into view, one thing is becoming clearer and clearer: The battle between democracy and oligarchy will be the defining battle of the 21st century.

Good news from the US today. AICOA, a bill that cracks down on anticompetitive practices from Big Tech was re-introduced in the Senate with bipartisan support. My quote in the Senate press release explains why @ProtonPrivacy is supporting this legislation: judiciary.senate.gov/press/r…

Terrible, and also misleading because the "Common Sense Reforms" actually expanded the scope of surveillance without meaningful safeguards. Here's what actually happened during the "reforms" in the last reauthorization: brennancenter.org/our-work/a…

The problem for #bitcoin isn't that the debasement trade is wrong, it's just no longer the best asset class. Gold (the original) now has higher speculative returns with better downside protection. Recovery will be tough until this dynamic changes.

Proton’s contribution of humanitarian aid isn’t expressing a political opinion, it’s expressing our humanity. Politics has nothing to do with it.

To help alleviate the humanitarian disaster in Gaza, Proton has donated $100,000 to the Palestinian Red Crescent Society and other aid organizations working on the ground.

So Signal, which much of Europe also relies upon, apparently runs on AWS, which is not great from a tech sovereignty standpoint. An European alternative not run on Big Tech cloud will be necessary to safeguard strategic autonomy.

Now Firefox users can choose whether they want Google or Perplexity to collect their data.

Perplexity is now an in-built default search option for all Firefox users. We look forward to working closely with Mozilla on a lot more things in the near future.

e-ID passed in Switzerland by around 20'000 votes. Had we emailed our users in Switzerland, NO could have won, but we didn't want to interfere with the democratic process. However, state-owned companies interfered by funding the YES campaign. Calls for a new vote are justifiable.
