Readyset DB: Optimizing Cold Path Query Performance with ICP

Readyset DB: Optimizing Cold Path Query Performance with ICP

Readyset database achieved a significant breakthrough in query performance during cache misses (cold path), specifically for straddled joins where predicates filter both join sides. The previous hash join algorithm proved inefficient due to extensive reads of irrelevant data. By introducing Index Condition Pushdown (ICP), Readyset combines the left-side predicate results with the right-side predicates, enabling precise data retrieval at the storage engine level, avoiding full table scans. Benchmarks show a >450x throughput improvement and >450x latency reduction, effectively resolving the performance bottleneck of cold path queries.

80% of Unicorns Will Fail or Stagnate: VC Prediction

2025-06-06

Venture capitalists predict a grim future for many tech unicorns. A staggering 80% are projected to either fail outright or become stagnant. 20% are expected to completely fail, while roughly half will struggle to grow, eventually selling for less than anticipated or existing in a zombie-like state. Only 20-25% are expected to succeed through an IPO or acquisition, and even among those, a small minority will become independent public companies. Even giants like Stripe, which have stayed private for years, may eventually choose to go public.

Student Discovers Psychedelic Fungus with Pharmaceutical Potential

2025-06-07

Corinne Hazel, a West Virginia University microbiology student, has discovered a new species of fungus, Periglandula clandestina, that produces ergot alkaloids similar to LSD. This discovery has significant pharmaceutical implications, as LSD is used to treat conditions like depression, PTSD, and addiction. Hazel's discovery, made while studying morning glory plants, was confirmed through genome sequencing. The fungus's high efficiency in producing ergot alkaloids opens new avenues for drug development and potential treatments for various ailments.

Texas Governor Vetoes THC Ban, Sparking Political Firestorm

Texas Governor Vetoes THC Ban, Sparking Political Firestorm

Texas Governor Greg Abbott vetoed a bill banning THC products just minutes before the deadline, immediately calling a special legislative session to strictly regulate the substance instead. This last-minute action saves the Texas hemp industry, but clashes directly with Lt. Gov. Dan Patrick's top priority. Abbott argued the ban was unconstitutional and conflicted with federal law, calling for a regulatory framework similar to alcohol, including prohibiting sales to minors and enhanced enforcement. Patrick sharply criticized the veto, claiming it abandons law enforcement and families harmed by high-potency THC products. The move highlights the complexities of Texas' hemp regulation and the intensity of the political battle, sparking debate over public safety, consumer rights, and political maneuvering.

Atari ST and DOS PCs: A Forgotten Disk Compatibility Story

2025-01-06

Atari ST and DOS PCs: A Forgotten Disk Compatibility Story

In 1984, Atari faced a challenge in getting an operating system for the Atari ST. Due to time constraints, they partnered with Digital Research, opting for their nearly-complete GEM OS instead of the then-unfinished Windows. GEM would later be ported to PCs, but it didn't gain traction. However, Atari ST's use of GEMDOS, similar to PC-DOS, and the identical disk format, allowed for surprisingly easy file transfers between the Atari ST and PCs. Despite minor compatibility issues, this was revolutionary at the time and remains relevant today. The article also recounts an attempt to run DOS programs on an Atari ST using pc-ditto, a third-party emulator. While slow, the ability to run some DOS applications showcases the Atari ST's unique charm in the retro computing world.

Technical Leadership: Connecting, Not Commanding

A senior developer reflects on their role: not as a technical expert, but as a bridge between teams. They translate complex backend issues into product-friendly language, coordinate communication across teams, and ensure alignment on team goals. Leadership isn't about possessing the most knowledge, but about effective communication and coordination, clearly defining problems, guiding teams to solutions, and empowering team members to excel. Ultimately, great leadership creates an environment where experts can thrive collaboratively, rather than trying to be the smartest person in the room.

Helm Dependency Update Vulnerability: Crafted Chart.yaml Can Lead to Local Code Execution

Helm Dependency Update Vulnerability: Crafted Chart.yaml Can Lead to Local Code Execution

A vulnerability in Helm allows for local code execution through a carefully crafted Chart.yaml file and a symlinked Chart.lock file during dependency updates. Fields from Chart.yaml are written to Chart.lock during updates. If Chart.lock is symlinked to an executable file (e.g., bash.rc), updating dependencies writes the Chart.lock content to the symlinked file, leading to arbitrary code execution. Helm v3.18.4 patches this; upgrade and check for symlinked Chart.lock files.

Model Context Protocol (MCP): A New Standard for Building Powerful LLM Applications

2025-04-13

This article introduces the Model Context Protocol (MCP), an open protocol for building enterprise-grade Large Language Model (LLM) applications. MCP solves the problem of a lack of standardization in integrating LLMs with enterprise tools, allowing frameworks like LangChain to seamlessly integrate with various data sources and tools such as databases and GitHub. The article details MCP's core components (MCP server, client, and host), installation setup, and Python hands-on demonstrations. These include building a LangChain application to calculate simple and compound interest using Ollama, and interacting with multiple MCP servers using both stdio and sse transport modes. With MCP, LLM applications can more effectively leverage enterprise data and tools for more powerful functionality.

22 Sailors Rescued After EV Fire Engulfs Cargo Ship

A fire broke out on the Morning Midas, a cargo ship carrying 3,000 vehicles (800 of which were electric), approximately 304 miles south of Adak, Alaska. The fire, believed to have originated from electric vehicle batteries, proved difficult to extinguish due to the salt water's conductive properties causing short circuits and thermal runaway in the batteries. All 22 crew members were rescued, but the ship is expected to continue burning until specialized firefighting crews arrive. This incident highlights the significant challenges posed by electric vehicle battery fires at sea.

The Trump administration is attempting to overturn the 90-year-old Humphrey's Executor case, a landmark Supreme Court decision that protects the independence of federal agencies. This move aims to bolster presidential power, allowing the president to fire agency heads at will. The move has sparked widespread concern, potentially undermining numerous agencies responsible for crucial areas like consumer protection, labor rights, and nuclear regulation, transforming them into potential tools for the President's political agenda. While the administration has so far avoided targeting the Federal Reserve, the underlying logic could equally apply, jeopardizing its independence. This legal battle carries profound implications for the future of the US government, redefining the relationship between executive agencies and the presidency.
