SFMTA Board of Directors Approves New Budget

SFMTA Board of Directors Approves New Budget
By Caroline Cabral

Our newly approved budget will help us continue to deliver the services San Franciscans depend on. Last week, our Board of Directors approved our next two-year budget. The budget is balanced and preserves crucial services. It prioritizes fast, safe and reliable Muni service. It maintains paratransit service. And it preserves free and discounted Muni fares for youth, seniors and people with disabilities. The directors approved an operating budget of $1.5 billion in FY26-27 and $1.6 billion in FY27-28. And they approved a capital budget of $655 million in FY26-27 and $546 million in FY27-28. Our...

Show HN: Time Pin – a Geo Guessr style game but history themed https://ift.tt/oln1s82

Show HN: Time Pin – a Geo Guessr style game but history themed Hi! Any history nerds here? I made Time Pin, a little game inspired by Geo Guessr but history-themed. You can play it here(it works on both desktop and mobile). Any feedback is appreciated: https://ift.tt/htqkmUZ Now some details: The goal is to guess the time and place that a character is from. You base your guess on some environmental photos, and on questions that you can ask the character(you have 12 questions but can only ask 5 so you have to choose carefully). The closer you are the more points you get. At the end, a portrait picture of the character is revealed, as well as educational resources to learn more about their culture and era(articles, videos, podcasts etc). The game only has 5 levels currently, but I hope to have over 100 someday. It’s tough to create levels because it requires some research, plus generating photos with AI(AI is necessary otherwise we’d only have photos starting from the 19th century when the camera was invented). My goal for the game was to create a challenge, and also maybe spark some curiosity for history. https://ift.tt/htqkmUZ April 27, 2026 at 12:46AM

Show HN: WaveletLM – wavelet-based, attention-free model with O(n log n) scaling https://ift.tt/Qe9VWbM

Show HN: WaveletLM – wavelet-based, attention-free model with O(n log n) scaling WaveletLM is a wavelet-based, attention-free architecture that replaces self-attention with learned lifting wavelet decomposition, a Fast Walsh-Hadamard Transform, per-scale gated spectral mixing with SwiGLU activation, an inverse FWHT, and wavelet reconstruction. Combined with expanded MLPs and sparse product-key memory, this yields a model with O(n log n) scaling in sequence length. With 23.8 PPL on WikiText-103, WaveletLM beats both GPT-2 Medium, which was trained on 80× more data, and Transformer-XL Standard, which uses recurrence to extend its effective context. It is undertrained and underregularized due to budget constraints, so there is much room for development and improvement. I invite anyone who is curious to examine the model, test it out, and extend its capabilities further. All code and weights are fully open source, and a PG-19 run will be completed in 2-3 days. Generations can be done in 4-5 GB VRAM at 28.8 tokens/second, and the model is trainable in 16.25 hours with 20 GB of VRAM, both on a 5090. README for comparison tables, instructions, logs, and future plans: https://ift.tt/AXhORWl Weights: https://ift.tt/Mc8z7AK Generations: https://ift.tt/HfWQYdb... The following samples were chosen for coherence, not factual accuracy. Factuality will require scaling and downstream techniques such as RAG and instruction tuning. > The history of the city is reflected in its architecture, which includes the historic Old Town and New Castle County Courthouse Square Historic District. The building was designed by John H. Stevens, who also designed the Albany-Fulton Celebration in 1906 and built a steel-hulled shipyard on the lake shore. > The album was released on August 25, 2007 by Sony Music Entertainment and features several songs from the record including "Never Say Die", "The Show", "Don't Cry for Me Argentina" and a cover of "I Can Only Imagine (But You Are Not Alone)". > The species was first described by Swedish zoologist Carl Linnaeus in 1758 as Agaricus adustus. The genus name is derived from the Latin words perma "to tie", and pous ("like") means "with a large head". In 1821, French mycologists Jean-Baptiste de Lacaille placed it in section Cricetae of the order Carnivora. He later renamed it Spongiforma punctata after the Greek kribensis. https://ift.tt/AXhORWl April 26, 2026 at 11:18PM

Show HN: SVG Fitter – Rust+WASM Vectorizer https://ift.tt/4RmKdLT

Show HN: SVG Fitter – Rust+WASM Vectorizer I went crazy with a tool that helps me tracing raster images. Thought other might like it. It doesn't auto vectorize image, but rather allow for guided process. Final SVG still should be edited. Few fun features like genetic algorithm fit optimization, semi-manual tracing and color preservation. Perfect if you want to have lightweight SVG from huge PNG image. Note: If there's interest I might open-source it, just not sure if anyone would want to see it :) https://svg.axk.sh April 25, 2026 at 10:21PM
