Opposition leader of the CDU and potential next German Chancellor, Friedrich Merz, delivered a fiery speech yesterday night in Stuttgart. I translated the core message.

Since I have been saying this for years and even carry this message in my signature, I approve this message by 100%.

Two years ago today, Russia launched a full-scale of Ukraine.

In the 38 days that followed, Russian forces were driven out of Kyiv, leaving nothing but horror in their wake.

My directorial debut tells the story of those who survived the Battle for Kyiv.

@SKankaansyrja No niinpä onkin! En itse ole aktiivisesti asiassa mukana enää, mutta laitan tämän tiedoksi eteenpäin.

So, let me get this straight. You just got out of college, and you think every system needs to be distributed? That's your big revelation? Let's think about that for a second. Distributed systems are complex, they're expensive, and they're a headache to maintain. You ever heard of KISS? 'Keep It Simple, Stupid.' That's Engineering 101.

You know what happens when you overengineer a solution? You end up with a mess of dependencies, network latency, and a nightmare of debugging. Ever heard of a single point of failure? Now imagine a dozen of them, scattered across different networks.

Oh, so every system needs to be distributed? What about a local bakery's inventory system? You think they need their doughnut count on five different servers Read Lamport's 'Time, Clocks, and the Ordering of Events in a Distributed System', did we? Or perhaps Brewer's CAP Theorem? It's charming, but let's get real. Distributed systems are not a panacea.

First, think about consensus algorithms. Paxos, Raft, Zab - they're not trivial. You've got to manage leader election, log replication, and handle network partitions and failures gracefully. Ever tried debugging a split-brain scenario in a distributed database?

Then there's data consistency. Sure, eventual consistency sounds great in theory, but have you considered the implications for transactional data? Read Eric Brewer's papers on CAP and then tell me about the trade-offs between consistency, availability, and partition tolerance in a high-volume e-commerce application.

Ever heard of a monolith? It's not a dirty word. It's a viable architecture for a vast majority of applications.

Scaling is not just about handling more requests. It's about handling more complexity. So, before you scale out, scale up. Optimize your monolith. Profile your database queries. Cache your responses. These are your bread and butter.

Next you're going to tell me that every application needs to be on the cloud, right? You read Werner Vogels blog and think you need cross-region replication for all your services. That it's cheaper and more scalable? That you can just spin up a kubernetes cluster and scale your application to hundreds of millions of users overnight?

Did you know that Capital One misconfigured an S3 bucket and it led to a massive data breach? Over 100 million customers' data exposed. That's the dark side of cloud computing. Misconfiguration. It's not just about throwing data on the cloud and calling it a day. It's about understanding the nuances of cloud security. Capital One's breach wasn't due to some high-level hacking wizardry; it was a configuration error.

Maybe use your own brain for once.

First independent measurement of zero resistance in LK-99

A team of scientists from the Physics Department of Southeast University, a top university in Nanjing, China, have reported measuring 0 resistance in a sample of LK-99 they synthesized from scratch.

Here is the video:
- They measure 0 resistance at 110K (-163C) using the four-point probe method. 0 resistance at this high of a temperature at ambient pressure is a new discovery in materials science
- They also claim a transition in and out of zero resistance state depending on a strongly applied magnetic field - a classic characteristic of superconductivity.
- The sample they synthesized is reported to have much higher purity than the original Korean team of LKK
- They note an interesting and abrupt drop in resistance, by several orders of magnitude, between ~300 and 220K (approx values from the graph). This is currently unexplained, but is in rough agreement with LKK - i.e., LKK may have been measuring this higher-temperature 'drop' which was two orders of magnitude.
- They retain the claim that this is not absolute conclusive proof of superconductivity, but it is suggestive of very interesting electronic properties in this material.

These results compare nicely with recent simulations out of Lawrence Berkeley National Lab, University of Boulder Colorado, Shenyang National Laboratory, and TU Wien, all performed by high profile and established materials scientists.

Those simulations have converged on LK-99 having the potential for superconductivity at high temperatures and ambient pressures due to the formation of flat energy bands when lead-apatite crystal is doped with copper. Notably, other doping metals may also achieve similar or better performance.

Here is a summary of those simulations: https://t.co/IPfJJF3vrW
