FastHTML allows building scalable web applications quickly using Python, integrating real-time data and reusable UI components.
It offers a quick start with a single Python file, full access to web technologies, and supports deployment on various platforms like Railway and Vercel.
Inspired by FastAPI, FastHTML is designed for creating modern Single Page Applications (SPAs) and enhances browser capabilities with HTMX.
FastHTML is a new framework for building modern web applications using pure Python, created by Jeremy Howard, known for founding Fastmail and leading Kaggle's first major production version.
The framework integrates Python with HTMX for hypermedia-based apps, the ASGI/Uvicorn/Starlette trio for asynchronous support, and a new Python component system called FastTag, inspired by functional programming.
FastHTML aims to simplify web app development by offering incremental complexity, easy customization, and a transparent system that allows developers to use JavaScript or modify requests directly.
Meta's FAIR team has introduced SAM 2, an advanced model for visual segmentation in both images and videos, extending the capabilities of the original SAM model.
SAM 2 employs a transformer architecture with streaming memory for real-time processing and includes a model-in-the-loop data engine, resulting in the creation of the SA-V dataset, the largest video segmentation dataset to date.
The model demonstrates strong performance across various tasks and domains, with different configurations available, such as sam2_hiera_tiny and sam2_hiera_large, each offering varying levels of performance and speed.
SAM 2: Segment Anything in Images and Videos has been released by the Segment Anything team, marking the first unified model for real-time promptable object segmentation in both images and videos.
The release includes code, models, a dataset, a research paper, and a demo, with applications in fields like biological research and video tracking.
The demo is not accessible in Illinois or Texas due to biometric privacy laws, but the model is praised for its performance and potential uses, such as automated annotations and object tracking.
On July 19, 2024, a CrowdStrike software update caused the largest IT outage in history, impacting 8.5 million Windows computers, including critical systems in hospitals, banks, and airlines.
The outage led to a significant reduction in air traffic for major airlines, with Delta experiencing a 46% reduction in flights, United 36%, and American 16%, while Southwest Airlines remained unaffected.
The prolonged recovery for Delta was due to the absence of a proper disaster recovery plan, highlighting the importance of robust contingency strategies in mitigating such disruptions.
CrowdStrike's impact on Delta Airlines was significant, particularly affecting their crew tracking software, leading to prolonged recovery times compared to other airlines.
Delta's reliance on a hub-and-spoke model and the timing of the disruption compounded the issue, making it difficult to reschedule flights and manage crew availability.
The incident highlights broader concerns about the robustness of IT operations and disaster recovery plans in major airlines, with some attributing the issues to underinvestment in IT infrastructure.
AI companies are being criticized for scraping OpenStreetMap (OSM) data without following best practices, leading to increased infrastructure costs and frustration among affected companies.
The suggestion is for AI companies to make a $10,000 donation to OSM instead of scraping, as a way to support the platform and mitigate the costs associated with heavy traffic.
The discussion highlights the broader issue of balancing open data access with the financial and technical burdens imposed by automated scraping, suggesting solutions like rate limiting, authentication, and proof of work.
The post details a procedural earth simulation created using GLSL fragment shaders, simulating an earth-like planet's history in minutes at 60 frames per second.
Key features include procedurally generated terrain, tectonic plate movement, hydraulic erosion, global climate modeling, and the impact of humanity on the environment.
The simulation uses advanced techniques like fractional Brownian motion noise, thermal erosion, and the Lotka-Volterra diffusion model to create realistic and dynamic planetary evolution.

The conversation includes nostalgic references to older simulation games and debates on the concept of living in a simulated universe.
Technical aspects such as GLSL fragment shaders are mentioned, along with book and story recommendations related to the topic.
Prioritizing pedestrian infrastructure over car-centric designs can make urban areas more walkable and improve quality of life.
Banning cars from city centers, except for emergency and goods vehicles, and reducing road lanes can enhance walkability.
Examples from cities like Houston and Salt Lake City illustrate the negative impact of car-centric planning and the potential benefits of prioritizing pedestrians.
Zig is transitioning @cImport to the build system to eliminate the dependency on libclang, making C file imports a build step rather than direct source code inclusion.

Google Deepmind's paper, "Scaling Exponents Across Parameterizations and Optimizers," involved over 10,000 LLM (Large Language Model) training runs to find optimal hyperparameters, with an estimated replication cost of $12.9M.
The total computational effort was 5.42e24 FLOPs (Floating Point Operations), with costs broken down into various experiments such as alignment, learning rate variants, and weight decay.
The analysis assumes the use of TPUs (Tensor Processing Units) with bfloat16 precision and provides Python code for detailed calculations, highlighting the significant but feasible compute resources required for replication.
The discussion revolves around the high costs associated with producing a Google DeepMind research paper, highlighting that such expenses are not uncommon in other scientific domains.
The costs include not just compute resources but also significant non-compute expenses like salaries, equipment, and consumables, which can run into hundreds of thousands of dollars.
The conversation also touches on the challenges of reproducibility in scientific research, especially when the original experiments are conducted using proprietary or highly specialized resources.
Researchers have developed a cost-effective method for training large-scale text-to-image (T2I) diffusion transformer models, significantly reducing computational expenses.
By employing techniques like random masking of image patches and using synthetic images, they trained a 1.16 billion parameter model for only $1,890, achieving competitive performance.
This approach is 118 times cheaper than existing stable diffusion models, and the team plans to release their training pipeline to make large-scale diffusion model training accessible on a micro-budget.
Rapid cost reductions in AI due to asymptotic improvements may render regulation irrelevant, potentially leading to more offshore models.
Open-source AI models are expected to improve, pushing big tech companies to enhance their offerings, though big players will likely continue to dominate due to their resources.
Training costs are decreasing, which could soon enable consumer-level training of large AI models, although sourcing comprehensive datasets remains a significant challenge.
LG and Samsung showcased see-through TV displays at CES 2024, featuring OLED and microLED technologies, respectively.
LG's transparent OLED displays offer about 45% transparency, while Samsung's microLED displays are more transparent but expensive and difficult to manufacture.
Practical applications for these transparent displays include retail signage, desktop video calls, and public transportation, rather than immediate consumer adoption in homes.
LG and Samsung are developing transparent OLED displays, which have been used in augmented reality projects and digital signage.
Transparent LCDs, requiring a backlight, are also part of this technological advancement but face challenges like black contrast, making them less practical for home TVs.
The technology is considered more suitable for specific applications such as automotive displays and advertising rather than general consumer use.
The author initially used Vercel's analytics on a pro plan but sought to reduce costs due to high outbound data usage from large PNG images.
By converting images to JPGs and building a custom analytics API using the "Squeeh stack" (SQLite-based apps), the author saved $13.27 per month.
The custom solution involved setting up an API with Bun and Hono, deploying on a VPS, and creating a basic analytics dashboard, which provided comparable data to Vercel's analytics.
