Same old story: I’m running the SaaS our CFO shipped to production in two days. A non-engineer exec builds something fast with Claude Code, and the engineer (me) goes through the back end one piece at a time. Every time I look, something crawls out. This time it wasn’t “where the secrets live,” and it wasn’t “there isn’t a single test.” This time, money burned. One day I was staring at the ...
Sandia National Laboratory built capacity to design and test ICs for radiation-hardened devices in the 1970s and 1980s for use in space missions and nuclear warheads. They successfully created the SA3000 processor, which could handle 1×106 rads of radiation with minimal performance reduction, and was used in the W88 nuclear warhead and other space applications.
The user successfully built Principia, an open-source game, to run on Windows XP by creating a custom toolchain and resolving dependencies, including a patch for GCC's C++ standard library. The user then installed Windows XP on real hardware, installed drivers and updates, and successfully ran Principia on the vintage operating system.
An AI resume screening tool is flawed due to non-deterministic outputs from its LLM, leading to inconsistent scores. This tool fails to differentiate between qualified and unqualified candidates, essentially filtering based on luck rather than quality.
A CUDA program is compiled into machine code that runs on a GPU, involving multiple compilers and transformations from PTX to SASS, and is then launched on the GPU through a complex process involving the CUDA runtime, driver, and kernel-mode driver. The GPU executes the kernel in parallel, using warps and scheduling control bits to hide latency and optimize performance, and eventually copies ...
GLM 5.2, an open-weight model, beat Claude Code at IDOR detection with 39% F1, costing $0.17 per vulnerability found. The harness still matters more than the model, but open-weight models have crossed a threshold worth watching for security tasks.
Google removed an article about Pollen's collapse from its search results due to a bogus copyright claim filed by a fake profile from an uninhabited island. The article's author suspects that Pollen or its former CEO hired reputation firms to file the claim, and is now investigating further lawsuits against the company.
A Haskell technique using RequiredTypeArguments and UndecidableInstances was employed to create a type-checked non-empty string constructor, resulting in a 10% build-time improvement in a large package. This technique can be used to define type-level predicates for any type, enabling type-safe validation and error messages.
The author shares lessons learned from founding two companies, zynamics and optimyze, and discusses the importance of understanding one's motivations and target market before starting a company. They also provide insights into the different types of markets, fundraising strategies, and the dynamics between founders and investors in the venture capital industry.

The author reminisces about the "computer room" of their childhood, where computers were bulky and had fixed locations, and how portable devices like laptops and smartphones have changed the way we interact with technology. The author now seeks to reintroduce boundaries and physical restrictions to minimize distractions and maintain a healthier relationship with technology.
A virtual machine on a NUMA host can be slow due to remote memory access costs, which can be mitigated by understanding the NUMA topology and making informed placement decisions. Xen's split design makes it challenging to manage NUMA, but Edera's stack of changes aims to make Xen-based virtualization NUMA-aware end-to-end, improving performance and predictability.
The user reverse engineered the ASIF file format used in macOS 26 Tahoe, discovering its structure and how to read from an arbitrary offset inside the virtual disk. The format uses a combination of tables, entries, and bitmaps to store and manage chunks of data, and the user provided a detailed explanation of how to calculate the correct chunk for a given offset.
US states and countries are introducing age verification regulations under the guise of protecting children, but it's actually a precursor to attributing digital identities to physical ones, making it easier for law enforcement to identify and harass individuals. This could lead to automated identity attribution and increased surveillance, allowing governments to target inconvenient people.
Linkerd's multicluster extension allows multiple clusters to present a service as a single endpoint, enabling federation, flat mirroring, and gateway mirroring modes. A demo setup with three GKE clusters and three services demonstrates how to mix these modes and shows how federation automates failover while mirroring gives clients control over which cluster they talk to.

The interactive dataset tracks historic and current memory and storage prices, including DRAM, NAND flash, and HBM, with modeled estimates from Epoch AI for AI-accelerator costs. The data is downloadable and includes quarterly updates for HBM and monthly updates for DRAM and NAND prices from 1957 to the present.
The author used Opus 4.8 to analyze an MRI and got a second opinion on their diagnosis, which disagreed with the original doctor's report. The AI analysis found no partial-thickness tear, contradicting the doctor's diagnosis and making the author question the treatment plan.

Two of Max Planck's papers were retracted from the journal Naturwissenschaften due to copyright violation, but the reason was likely a misunderstanding of past publication practices. The retractions distort the historical record and have sparked debate about applying contemporary standards to historical papers.
Cloudflare's Images service experienced intermittent truncation of image data due to a race condition in the hyper library that occurred when the reader consumed data slower than hyper wrote it. The issue was resolved by adding a flush before shutdown in the hyper library, ensuring that all data is sent before closing the connection.
Zanagrams is a free daily word puzzle. Drag across the letters to find the hidden words and watch the grid shrink as you solve it. A new Zanagrams puzzle every day.
Researchers introduced Proxy-KD, a method to transfer knowledge from black-box LLMs to smaller models efficiently. Proxy-KD surpasses traditional white-box KD techniques and enhances performance.
The KIDS Act package includes bills that require age verification, government-directed moderation, and new rules for private communications. This could lead to restrictive age-checking practices, reduced online privacy, and limited free expression.
The concept of tokenmaxxing, where companies spend large amounts of money on AI tokens without expecting a return, is not dead but rather evolving as companies realize the benefits of compounding correctness, where more tokens spent lead to better results. The shift towards open model platforms and generalist agents will lead to another rise in tokenmaxxing behavior, ultimately resulting in ...
Professor Roberto Serrano at Brown University detected massive cheating on a midterm exam using AI, with at least 50 students involved. He believes the university's response was inadequate and that AI is altering century-old traditions at elite universities, requiring a broader debate on academic integrity.
