‘Curb Your Enthusiasm’ Footage Saves Innocent Man from Death Row

Juan Catalan, a California man, faced the death penalty for a murder he didn't commit. The sole eyewitness's description matched Catalan, despite his pleas of innocence. His girlfriend remembered he was at a Dodgers game the night of the murder. His lawyer secured footage from an HBO filming of 'Curb Your Enthusiasm' at the stadium, showing Catalan and his daughter, proving his alibi. This unexpected evidence led to the dismissal of charges, highlighting the fallibility of eyewitness testimony and the risk of wrongful convictions.

Crystal Ball Challenge: Knowing the Future Isn't Enough to Guarantee Riches

Elm Partners conducted an experiment called the "Crystal Ball Challenge," where 118 finance students traded stocks and bonds using the Wall Street Journal's front page from one day in the future (with price data blacked out) over 15 days. The results were surprising: despite having future information, most participants didn't profit, averaging a mere 3.2% gain. Experienced traders, however, performed exceptionally well, averaging a 130% gain. The experiment demonstrated that even with 'future' knowledge, successful investing requires sensible position sizing. This research highlights the importance of decision-making under uncertainty and position sizing, offering valuable lessons for financial education.

Whittaker's Keynote at NDSS 2024: AI, Encryption, and a New Era of Threats

At the 2024 NDSS Symposium, Meredith Whittaker, president of the Signal Foundation, delivered a keynote address reflecting on the 'Crypto Wars' of the 90s. She highlighted how political, technical, and commercial pressures have shaped today's encryption landscape. Whittaker warned against viewing the current situation as simply 'Crypto Wars 2.0,' arguing that an economic engine driven by personal data, surveillance technology, and AI/ML poses a fundamentally different threat than the government-dominated encryption landscape of the 90s. She stressed the need for a new approach, with NDSS research at the forefront of this response.

Bloom Filters: The Secret to Making SQLite 10x Faster

2024-12-22

Researchers cleverly used Bloom filters to make SQLite analytical queries 10x faster. They discovered that SQLite's nested loop joins were inefficient, with much time spent on B-tree probes. By using a Bloom filter before the join operation to quickly filter out rows unlikely to match, and then performing B-tree probes only on potential matches, the number of probes was significantly reduced. Bloom filters have minimal memory overhead and were easy to integrate into SQLite's existing query engine, resulting in a significant performance boost. This improvement has been integrated into SQLite v3.38.0.

LLMs: Exploring Arithmetic Capabilities in the Pursuit of AGI

This article explores why large language models (LLMs) are being used for calculation. While LLMs excel at natural language processing, researchers are attempting to make them perform mathematical operations, from simple addition to complex theorem proving. This isn't to replace calculators, but to explore the reasoning capabilities of LLMs and ultimately achieve artificial general intelligence (AGI). The article points out that humans have always tried to use new technology for computation, and testing the mathematical abilities of LLMs is a way to test their reasoning abilities. However, the process of LLMs performing calculations is drastically different from that of calculators; the former relies on vast knowledge bases and probabilistic models, while the latter is based on deterministic algorithms. Therefore, LLM calculation results are not always accurate and reliable, highlighting the trade-off between practicality and research.

Spacer CLI Tool: Elegantly Separate Log Outputs

Spacer is a simple CLI tool that inserts spacers when command output stops. If you're someone who habitually presses enter a few times in your log tail to distinguish between outputs from different requests, then Spacer is for you! By default, it inserts a spacer every 1 second, but you can customize the interval using the `--after` flag (floating-point numbers are supported). Note that Spacer only monitors STDOUT; if your command outputs primarily to STDERR, use `|&` instead of `|` to redirect STDERR to STDOUT.

Rust-based SQLite Rewrite Achieves 100x Tail Latency Reduction

2024-12-16

Researchers from the University of Helsinki and Cambridge have rewritten SQLite in Rust, creating Limbo, a project leveraging asynchronous I/O and io_uring to drastically improve performance. By utilizing asynchronous I/O and storage disaggregation, Limbo achieves up to a 100x reduction in tail latency, particularly beneficial in multi-tenant serverless environments. The key improvement comes from replacing synchronous bytecode instructions with asynchronous counterparts, eliminating blocking and enhancing concurrency. While improvements are most pronounced at high percentiles, this makes Limbo ideal for applications demanding high reliability.

Doomsday Predictions: Why People Always Feel the End is Nigh

Doomsday Predictions: Why People Always Feel the End is Nigh

From Columbus's time onward, doomsday predictions have accompanied humanity. The author argues that people believe in them not for comfort, but because they seem logical. A 'Good Cup Bad Cup' theory is introduced: people pay more attention to bad things, and negative memories fade faster, leading to a perception that bad things are increasing and the world is deteriorating. Historical examples, from ancient Egyptian prophecies to the Millerite movement, support this: people always feel the present is worse than the past. The author calls for a rational perspective, urging readers to avoid biases and recognize positive changes.

A Glimpse into OS/2's Built-in Virtualization

2024-12-17

This blog post explores the surprisingly advanced built-in virtualization capabilities of OS/2 2.1 from 1993. The author demonstrates OS/2's ability to load and execute disk images, much like modern hypervisors, by creating a simple VGA mode program and running it in DOSBox, QEMU, and OS/2's own virtual environment. OS/2 can even run images that aren't true bootable DOS floppies, using VMDISK to create an image file and running it in fullscreen or windowed mode within OS/2. This functionality, remarkable for 1993, is essentially a built-in QEMU, prompting the author to consider the further potential of OS/2's virtualization features.

Debunking the RAM Myth: Optimizing Memory Access

This article challenges the common misconception about modern computer memory—the RAM myth—that assumes memory access is always random and uniform. By analyzing data sharding algorithms, the author demonstrates that simple linear algorithms are inefficient for large datasets due to frequent cache misses. To address this, an optimized strategy based on radix sort is proposed. Techniques like pre-sorting data, using generators, and pre-allocating memory significantly improve data sharding efficiency. Experimental results show that the optimized algorithm achieves a 2.5 to 9x speedup when processing large datasets.
