The article discusses the challenge of determining the temperature of ground beef, and suggests that bakers should start using thermometers on their baked goods. Many recipes provide visual cues for determining when something is fully baked, but using a thermometer can provide more accurate results. The author mentions that most baked goods should reach an internal temperature of around 190F before they are ready. This is particularly useful for items like cinnamon rolls with a gooey filling that can appear fully baked on the outside but still be undercooked inside. The author notes that they previously only associated thermometers with cooking meat and syrup, so this insight was revelatory for them.

The article discusses the problems with the way politicians pass controversial laws, often influenced by lobbyists with little concern for public benefit. The author suggests that people need to engage in activism to prevent the passing of such laws. However, they highlight the frustrating cycle of politicians and lobbyists reintroducing these controversial measures under different names or sneaking them into other laws after public attention has waned.

The European Commission used “microtargeting” to prevent certain individuals, such as privacy-minded people and eurosceptics, from seeing their ads in order to sway European public opinion. This raises concerns that institutions are creating echo chambers and excluding certain demographics from political discourse.
4. Anything longer ago than yesterday should just say the actual date
Total comment counts : 65
Summary
The author of the article argues that labels such as “yesterday,” “2 days ago,” and “a week ago” used in computer interfaces do not accurately reflect how humans think about time. While humans consider “yesterday” to mean the day before, from midnight to midnight, computers define it as less than 24 hours ago. Additionally, different computer systems may interpret these labels differently, leading to a lack of trust and usefulness. The author also criticizes the use of labels like “12 days ago,” stating that humans do not think in terms of “5+ days ago.” Instead, they suggest using specific day references rather than vague time periods like “last week/month/year.”

The article discusses how the time frame “1 year ago” on YouTube can be misleading because it can represent anywhere from 365 to 729 days. This means that if there are two videos uploaded “a year ago,” it is impossible to determine which one is more recent without actually opening the videos and checking the date in the description.

The author of the article is expressing frustration with the lack of specific timestamps provided when browsing npm versions of packages. They are trying to figure out the release order of older packages to create a build configuration. The author criticizes the inconvenience of having to check each package individually to determine if it is too recent to use. They also mention their dissatisfaction with ORM builders that map table names incorrectly.

6. PostgresJs: PostgreSQL client for Node.js and Deno
Total comment counts : 29
Summary
The article provides an overview and instructions for using Postgres.js, a fast and feature-rich PostgreSQL client for Node.js. It covers topics such as database connections, query execution, parameter handling, query building, transactions, error handling, and several other features and options provided by Postgres.js. The article also includes information on TypeScript support and provides examples and code snippets for various use cases.
Top 1 Comment Summary
The author of the article expresses their preference for using plain SQL statements in JavaScript when working with Postgres, rather than using more abstract options like Prisma. They found that working with Postgres in this way brought them joy and was a more straightforward approach for them compared to other TypeScript libraries. The author discovered this method a couple of years ago after becoming frustrated with Prisma and trying out various other options.
Top 2 Comment Summary
The article discusses a fast library that is not dependent on other libraries and has its own low-level client implementation. The author claims to have built systems successfully using this library to load multiple 10k records at a time.
7. Implementing a GPU’s programming model on a CPU
Total comment counts : 11
Summary
This article discusses the programming model of a GPU, specifically focusing on the concept of “single instruction multiple thread” (SIMT). The author explains that programmers write their programs from the perspective of a single thread, but the system runs the program in parallel with different thread IDs. GPUs optimize this process by using vector registers and instructions to run multiple threads simultaneously, improving performance. The article also explains how SIMT handles control flow using predicated instructions and bitmask registers. The author then describes their implementation of SIMT transformation using the AVX-512 instruction set, providing insights into how real GPU compilers work. The article also touches on topics such as variables, literal math, pointers, and function pointers in SIMT. The author emphasizes that their implementation is for learning purposes and not focused on achieving maximum performance. The article concludes by mentioning that the programming language the author implemented supports control flow and provides a link to the author’s implementation.

The author of the article describes their experience creating a modified version of the RISC-V architecture for a class project. They explain that they compiled programs to WebAssembly (WASM) using clang, then converted the resulting WASM back to C, but this time using RISC-V vector intrinsics for all opcodes. They found this approach to be a clever solution, as WASM’s structured control flow aligns well with lane masking, stack and local values can easily utilize a “structure of arrays” layout, and heap values can easily use an “array of structures” layout. Although the project did not gain much traction, the code is still available online for those interested.

The article discusses various implementations of graphics processing units (GPUs) and their capabilities. It mentions ISPC, SwiftShader, Lavapipe, and WARP as examples of software fallback implementations of GPU APIs. The author expresses disappointment that Larrabee, a parallel computer with GPU-like efficiency and CPU-like agility, did not gain popularity due to power consumption issues. The article includes a link for more information on WARP.

10. Daily energy expenditure through the human life course
Total comment counts : 15
Summary
The article discusses the trajectory of total daily energy expenditure (total expenditure) throughout the human life course. The researchers analyzed a large database of total expenditure measured using the doubly labeled water method for males and females aged 8 days to 95 years. They found that total expenditure increases with fat-free mass in a power-law manner and identified four distinct life stages. Total expenditure accelerates rapidly in neonates, declines slowly and reaches adult levels by around 20 years of age, remains stable in adulthood (20 to 60 years) including during pregnancy, and then declines in older adults. These findings provide insights into human development and aging and can help shape nutrition and health strategies across the lifespan.

The author shares their personal experience of having a high metabolism and being able to eat unhealthy foods without gaining weight as a teenager and in university. They mention consuming chocolate bars, carbs, and alcohol regularly. Despite this, they were thin and had low body fat. However, around the age of 25, this changed, and they had to start watching what they ate to avoid gaining weight. The author wonders what could explain this shift in their metabolism and ability to gain weight.

This article explains that muscle burns more energy than fat. As individuals get older and their muscle mass decreases due to lack of exercise, it is common for their metabolism to decline. This decline happens even if the “metabolism per kg of muscle” remains unchanged.
