- **Debunking NIST's calculation of the Kyber-512 security level (2023)**  
  NIST's calculation of Kyber-512's security level is fundamentally flawed, as it mistakenly multiplied costs that should have been added, leading to a gross overestimation of its security against AES-128.

- **AbsenceBench: Language Models Can't Tell What's Missing**  
  AbsenceBench reveals that while large language models (LLMs) excel at recalling information, they struggle significantly with identifying missing elements, achieving only a 69.6% F1-score on tasks designed to test this ability.

- **TPU Deep Dive**  
  TPUs excel in scalability due to their co-designed hardware and software, notably the XLA compiler, which optimizes performance by minimizing memory access and maximizing throughput.

- **Scaling our observability platform by embracing wide events and replacing OTel**  
  LogHouse has scaled from 19 PiB to over 100 PB, managing nearly 500 trillion rows of uncompressed logs, while achieving a 20x increase in event volume with less than 10% of the CPU previously required, thanks to the development of a specialized tool called SysEx.

- **AllTracker: Efficient Dense Point Tracking at High Resolution**  
  AllTracker introduces a novel model for long-range point tracking, achieving high-resolution dense correspondence fields by estimating flow between a query frame and multiple subsequent frames, rather than just the next one.

- **Load Test GlassFlow for ClickHouse: Real-Time Dedup at Scale**  
  GlassFlow demonstrated robust performance by processing over 9,000 records per second with sub-0.12ms latency, effectively handling deduplication for 20 million records without crashes or message loss.

- **[D] RL/GRPO for lossless compression of text passages into 'least token representation', then using this emergent 'language' as the basis for reasoning instead of english**  
  This entry discusses a novel approach for compressing text.
