Show HN: SignalDB – Reactive Local JavaScript Database https://ift.tt/DcStNT1

Show HN: SignalDB – Reactive Local JavaScript Database SignalDB is a local JavaScript database with a MongoDB-like interface and TypeScript support, enabling optimistic UI with signal-based reactivity across multiple frameworks. It integrates easily with libraries like Angular, Solid.js, Preact, and Vue, simplifying data management with schema-less design, in-memory storage, and fast queries. https://ift.tt/hCQRd3e October 20, 2023 at 11:35PM

Show HN: Linkitall – create dependency-graphs of ideas https://ift.tt/xK4lkWR

Show HN: Linkitall – create dependency-graphs of ideas What is the structure of knowledge? It's a broad question, and finding a structure that suits everyone is no easy task. Consider this: a backend developer might view knowledge as a table accessible with different keys, while a teacher might perceive it as a book, complete with chapters, sections, and subsections—a linear structure, yet with a tree-shaped Table of Contents for efficient reference. Generally, the structure we require depends on (a) the data involved and (b) the purpose at hand. Let's narrow it down: What's a suitable structure for teaching scientific knowledge? In the context of a specific course, one can assert that certain ideas are more fundamental than others. There's a hierarchy of ideas, where complex ideas build upon simpler ones, and those, in turn, rest on basic concepts. In simpler terms, with the exception of a few obvious or axiomatic ideas, every other idea relies on something else. Organizing all these ideas into a graph based on their dependency structure creates a dependency graph. Using graphical structure (including dependency graphs) to arrange ideas for presentation or teaching is nothing new. There are several tools out there, but none of them really worked for my use-case. So I wrote a tool in Golang which will take a graph definition in YAML format and produce a graph output in HTML. I am a noob in Golang. I am using python for work, so I wanted something else for this "hobby" project, and ended up with Go. This is the tool: https://ift.tt/wRWIhc2 Here are a few example outputs: Sets: https://ift.tt/h7fvRrF... Trigonometric relations: https://ift.tt/h7fvRrF... Note: one can click on the node name and it will open the associated slide. Kindly let me know what you fellows think. In particular, I would very much appreciate feedback from those in training/teaching/research background. https://ift.tt/wRWIhc2 October 19, 2023 at 04:40PM

APEC is Coming to SF! What You Need to Know to Get Around

APEC is Coming to SF! What You Need to Know to Get Around
By Mariana Maguire

Map of the main security zone around the APEC conference at Moscone Center, with vehicle detours. Security zones have been set and are managed by the United States Secret Service. Only conference attendees and those who live or work inside this zone will be allowed to enter following security screening procedures.

San Francisco is proud to host the Asia-Pacific Economic Cooperation (APEC) conference in November, one of the largest gatherings of global leaders in San Francsico. This is an exciting opportunity for San Francisco to shine on the world stage. Most APEC activities will take place in the South of Market and Nob Hill neighborhoods. Due to the scale of the gathering, APEC may have some impacts on travel in other areas of San Francisco as well. The bulk of the travel and transit impacts will take place from Nov. 14-19.

More than 20,000 people are expected to attend this historic conference, including heads of state and dignitaries from over 20 member economies in Asia, the Pacific, North America and South America. Visit the APEC website (APEC2023SF.org) for further information about the conference.

For security, areas around events and activities will be closed to vehicles and pedestrians except for event attendees or people who live or work within the security boundaries.

Street Impacts

Streets and freeway ramps in SoMa will be closed from Tuesday, Nov. 14 - Sunday, Nov. 19. These closures will result in significant traffic impacts.

Visitors and residents — whether driving or taking Muni or SF Paratransit — should expect congestion downtown, traffic delays, transit reroutes and potential crowding on Muni during the APEC conference and any additional conference-related events or activities. Additional events and activities may arise with little notice and may impact Muni and SF Paratransit routes, as well as traffic and pedestrian access.

Additional APEC-related events will take place in multiple locations. Some events require a temporary security zone that will restrict traffic and may require Muni reroutes. We will make information available as events are announced.

Please note that predictions and third-party navigation apps may not display information properly during this period. We advise Muni customers and anyone traveling through the city to allow ample extra time for travel and be prepared for possible delays.

We understand that these changes will present some challenges and we appreciate your support and patience as San Francisco hosts one of the world’s premier global leadership events.

For the most up to date information in real-time, subscribe to our Muni SMS and/or email alerts. For free language assistance, please call 3-1-1 within San Francisco or 415-701-2311 outside of San Francisco. For TTY, press “7”.

Muni Impacts

For additional details on transportation impacts visit our main APEC page (SFMTA.com/APEC).

The following lines will be impacted:

• T Third Muni Metro
• T Third Bus
• 1 California outbound
• 5 Fulton Owl
• 8 Bayshore, 8AX Bayshore Express A and 8BX Bayshore Express B
• 12 Folsom inbound
• 14 Mission and 14R Mission Rapid

• 30 Stockton
• 45 Union-Stockton
• 91 Owl
• 714 BART Early Morning Shuttle
• California Cable Car
• Powell/Mason Cable Car
• Powell/Hyde Cable Car
• 18 46th Avenue (single day reroute)
• F Market and Wharves (single day reroute)

The 30 Stockton and 45 Union-Stockton will only operate north of Market Street and continue to serve connections from Union Square to Chinatown, Fort Mason, The Marina and the Presidio.

Temporary KT Ingleside-Third substituting T Third service

T Third and K Ingleside Muni Metro stops from Balboa Park to Embarcadero to Sunnydale will be served by a temporary KT Ingleside-Third Muni Metro from Nov. 14 - 19. This includes Embarcadero at Folsom and Brannan, and King at 2nd and 4th streets. Customers should look for train head signs that indicate the K Ingleside westbound, T Third eastbound or KT Ingleside-Third.

There will be no Muni Metro service provided to 4th & Brannan or Yerba Buena-Moscone Stations.

A Muni Metro shuttle train will operate every five minutes between Chinatown-Rose Pak Station and Union Square-Market Street Station to maintain access to Chinatown and areas north of downtown. Transfer at the Powell Street Station to Union Square-Market Street Station access the temporary shuttle.

Show HN: I struggle to focus working from home so I built a solution https://ift.tt/qNPyJLh

Show HN: I struggle to focus working from home so I built a solution Hey HN friends, I keep getting distracted working from home and always end up watching youtube, browsing blogs like HN or just mindlessly scrolling then I feel like crap because I didn’t do enough. I went through dozens of productivity tools but they’re quite overwhelming to use and none of them actually helped me focus. So I built http://complish.ai, a web-based sidebar that helps me focus on one task at a time. I launched it last month and have over 3,000 users now and I’ll be keeping it free. Would love for you all to try and give some feedback! October 19, 2023 at 12:45AM

Show HN: Finetune OpenAI Embeddings In-Browser https://ift.tt/tNRKafx

Show HN: Finetune OpenAI Embeddings In-Browser There's a lesser-known trick described in the OpenAI Cookbook. You can linearly transform a generic embedding space (like OpenAI’s) for your usecase with a well-tuned matrix multiply. I ported the cookbook technique into a standalone hardware-accelerated webapp, and added some UX to guide the process along. There are some examples on the homepage for out-of-the-box fun. With 30 seconds of training, I was able to improve performance by the first example by 15%. https://ift.tt/MyZoi24 October 18, 2023 at 10:45PM
