Show HN: Asymptotic Growth Order Calculator https://ift.tt/1D57fVE

Show HN: Asymptotic Growth Order Calculator I'm an undergraduate student and for my math honors thesis I'm studying asymptotic growth orders, the kind you usually see written in "big-Theta" notation to describe an algorithm's time/memory usage. The most interesting part was studying how to compute the growth order of the sequence of partial sums of a given sequence - that is, the growth order of (a_1 + ... + a_n), in terms of the growth order of (a_n). So I thought I would make a little web calculator for playing around with this. Enjoy! :-) Some things to try: 1. The sums of the harmonic sequence (1/n) diverge, but can you find a faster-decaying sequence that also has diverging sums? 2. Can you make the growth order log(log(log(n))) using only one register? 3. What happens when you apply Σ⅟ΣΣΣ (applied from right to left) to any growth order, and why? https://ift.tt/7lkhaQz January 9, 2024 at 11:22PM

New State Laws Are Coming to the Streets of San Francisco

New State Laws Are Coming to the Streets of San Francisco
By Melissa Culross

People walking and on bicycles in the street and crosswalk. As of Jan. 1, 2024, bicyclists in California legally can cross a street on a pedestrian walk signal, instead of waiting for a traffic light.

Several new state laws that took effect on Jan. 1, 2024, will have an impact on transportation in San Francisco. Some of these impacts will be more widespread and immediately felt than others, but all are expected to make San Francisco streets safer.  

Street Safety and Vision Zero

AB 251 (Ward) - This law requires the California Transportation Commission (CTC) to study the relationship between vehicle weight and injuries to vulnerable road users, such as pedestrians and cyclists. Vehicles have been increasing in size and weight in recent years, while pedestrian fatalities in the U.S. reached a four-decade high in 2021. The CTC will also study the possible costs and benefits of a passenger vehicle weight fee and how the funds created by such a fee might be used to improve road safety.  

AB 361 (Ward) - This law authorizes local agencies to install forward-facing cameras on city-owned or district-owned vehicles to enforce bicycle lane violations. AB 361 gives the agency another tool to support the safety of bicyclists by expanding our capacity to enforce regulations against cars blocking bike lanes. The legislation allows our enforcement officers to take still photos of bike lane parking violations until Jan. 1, 2030. The SFMTA plans to take the opportunity this legislation affords us, but a technology review will be necessary before cameras can be installed. 

AB 413 (Lee) - This new law prohibits the stopping, standing or parking of a vehicle within 20 feet of any crosswalk, whether it’s marked or not, and within 15 feet of a crosswalk with a curb extension. This change, known as “daylighting,” will only apply to the approach side of an intersection, and cities will have the ability to allow parking within 20 feet of a crosswalk that has clear signage or a painted curb. The legislation requires warnings to be issued until the beginning of next year, unless a violation occurs in an area marked with paint or a sign. The SFMTA has been a strong proponent of daylighting to increase pedestrian safety. Keeping the area next to crosswalks clear of parked vehicles allows pedestrians, drivers, bicyclists and anyone else rolling down the street to see each other more clearly. We are reviewing AB 413 and how it will be implemented in San Francisco, including how we can work with safety advocates, other cities and the DMV to increase awareness about the law.  

AB 645 (Friedman) - This law gives San Francisco, Los Angeles, Oakland, San Jose, Long Beach and Glendale the authority to implement a five-year speed safety camera pilot program. The speed cameras will be used on San Francisco’s High Injury Network, the 12% of streets where more than 68% of severe and fatal traffic crashes occur, and possibly at other locations where speeding is a known issue. Unsafe speed is the number one factor in fatal traffic crashes in San Francisco. We are working to identify potential locations for the speed cameras and developing a plan for outreach and engagement with local stakeholder organizations, including racial equity, privacy protection and economic justice groups.  

AB 1909 (Friedman) – Most of this law, an omnibus bicycle bill, went into effect last year, but an important provision took effect on Jan. 1, 2024. AB 1909 amends the vehicle code to make it legal for people riding bikes to cross the street on a pedestrian walk signal, unless otherwise directed by a bicycle control signal. Previously it was only legal for bikes to cross the street on a green traffic light with automobile traffic. 

Transit Safety 

SB 434 (Min) - This law is intended to reduce the harassment of women and other vulnerable groups on public transit by collecting better data on these incidents. It requires the state’s ten largest transit agencies by ridership, including the SFMTA, to conduct public outreach and survey riders about their experiences with safety while waiting for or riding on transit. This legislation builds upon the SFMTA’s Safety Equity Initiative that is currently underway. Last year we launched MuniSafe, a campaign to enhance security and increase the reporting, investigation and prevention of harassment and assaults on Muni.

Show HN: Dashwave – Fast Android cloud build tool with collaborative emulators https://ift.tt/rYOI6f2

Show HN: Dashwave – Fast Android cloud build tool with collaborative emulators Introducing Dashwave Public Beta! Hello, I am Supratik Das, Co-founder, and CTO at Dashwave. I am thrilled to announce the launch of Dashwave, a powerful cloud build and emulation tool for fast and collaborative Android development. It supports all major Android languages/frameworks: Java, Kotlin, React Native and Flutter. Why Dashwave? - The Problem Android developers often struggle with insanely long build times and resource-intensive emulation sessions. They work in close collaboration with product stakeholders and rely on WIP feedback. Since builds, and feedback are slow, this leads to a 'code more, build less' approach, causing debugging challenges due to insufficient testing and productivity losses. Solutions exist but their scope is limited either as a general-purpose build tool or a CI/CD build tool. At Dashwave we are tailoring the entire platform right from the local development stage for the use cases of Android Developers. What is Dashwave? - The Solution With Dashwave, you can quickly onboard your project, fire your local build on Dashwave’s cloud, preview the native emulated app interactively streamed to the browser and share emulation for feedback/demo/anything you want. Don’t believe me? Watch this video where I do all the above three in 5 minutes: https://www.youtube.com/watch?v=uQpmVfyF44o KEY FEATURES Integration with IDEs/Editors: Integrate local code with our build engine using DW CLI. Attach an Android debugger while you build and emulate on our cloud. Cloud Builds: Get fresh build environments with no dependency conflict. Build on powerful cloud nodes tapping parallelization. Supports Java, Kotlin, React Native and Flutter Remote Caching: Dashwave uses Gradle Enterprise grade Distributed Caching to speed up your builds. If a project was built historically by anyone on Dashwave, future users will enjoy cached builds. Build Analytics: Analyse build performance and dev productivity with Builds ROI stats, cache utilisation metrics Cloud Emulation and Previews: Preview your built app on cloud emulators, interactively streamed to your browsers. You can also connect your physical device to Dashwave Cloud to enjoy real device previews. Collaborate: Share your emulated app build as a link to anyone, exchange contextual comments with screenshots and logs to get feedback. Reduce CI Headaches: Use a singular ground for development and CI builds. If it builds on dev, it will build on CI. Security and Privacy: Rest easy knowing that your data and intellectual property are protected by the latest security measures. Visit https://dashwave.io to know more. Join our discord server for help and the latest updates. Start creating your first build on ( https://ift.tt/OkiPCNF ) We can't wait to see what you create with Dashwave! Happy building! https://ift.tt/qUbxXJC January 8, 2024 at 09:34PM
