Muni Metro Fix-It Week Maintains the Subway Infrastructure

Muni Metro Fix-It Week Maintains the Subway Infrastructure
By Jessie Liang

Track crew removing old rail at the Van Ness crossover 

The first Muni Metro Fix-It Week of 2023 was a resounding success in March, and it’s also the first Fix-It Week since the SFMTA launched the Central Subway in early January of this year. Here is a behind-the-scenes video recap. Fix-It Week is the SFMTA’s quarterly effort to optimize work time by closing Muni Metro early for critical maintenance. The SFMTA’s Maintenance of Way (MOW) teams did an excellent job maintaining the subway and preventing future breakdowns. 

Fix-It Week helps the Muni Metro get a 20% improvement in speed and about a 20% improvement in reliability in the subway. It takes fewer minutes to take the N Judah from the Outer Sunset to Embarcadero now than it did in 2019. 

 From March 16 to March 22, 2023, the Muni Metro Subway between Embarcadero and West Portal closed at 9:30 p.m. to provide SFMTA maintenance crews an extended window to perform underground infrastructure improvement work that cannot be completed during the usual overnight windows. During the subway closure, buses provided substitute service for Muni Metro lines on the surface and connected all stops on Market Street.   

Track crew powerwashing station walls

The goal of Fix-It Week is to make Muni metro subway operations more reliable, ensure safety, and improve the customer experience. Nine MOW teams, Track, Cable Car, Motive Power, Maintenance Engineering, Mechanical Systems, Overhead Lines, Underground, Paint Shop and Signal, were involved in the maintenance work. 

Major maintenance work includes: 

• Track replacement and reinstallation from the Ferry Portal to the Van Ness Crossover 
• Mechanical systems cleaning, maintenance and installation  
• Signal repairs and upgrades, including the demolition of old train control system racks, equipment and wiring 
•  Track fastener and subway lighting surveys, and drain cleaning around switches  
• Overhead Line inspections and Overhead Section Break hardware adjustments 
• Debris removal and traction power substation inspections 
• Cable Car maintenance and repairs 

Custodial staff cleaning Church Station

The SFMTA teams completed over 2,000 hours of maintenance and inspections over the seven night shutdown. They were able to perform 161 feeder operations, replace more than 125 bulbs for trackway lighting in multiple locations, renew 750 feet of Overhead Contact System contact wire, replace eight blue light phones and inspect approximately 8,000 track fastener plates from the Ferry Portal to Powell Station. 

Track crew powerwashing and removing trash from trackway 

A support team was also contributed to the success of Fix-It Week. These staffers helped coordinate maintenance work, upheld all safety standards and ensured that subway service resumed on time every day. 

The SFMTA will continue to keep the Muni Metro system in a state of good repair. The next Fix-It Week is scheduled for July 2023, and we thank you for your patience and understanding while we do this vital work.

Show HN: Code-Narrator: Automating Documentation with GPT-4 https://ift.tt/yTzDcMb

Show HN: Code-Narrator: Automating Documentation with GPT-4 As a solo developer on a sizeable project, I found myself facing the challenge of creating documentation, a task I admittedly do not enjoy. Fortunately, ChatGPT arrived just in time. After experimenting with it, I discovered that it generates high-quality documentation for code files, even better than what I could produce manually. This realization led me to develop Code-Narrator, a client that simplifies the documentation process. Code-Narrator ( https://ift.tt/6nbqjS9 ) utilizes GPT-4 to analyze your code files and automatically generate documentation. The tool is language-agnostic and has been tested with TypeScript, GraphQL, Solidity, C#, Kotlin, and more. As long as the files are in plain text, Code-Narrator should work seamlessly. The primary goal of Code-Narrator is to ease the documentation process for developers, transforming them from writers to editors. While developers are still responsible for verifying the accuracy of the generated documentation, the initial writing is handled by the AI. If GPT-4 produces incorrect documentation, it typically indicates that the code needs clarification, or a brief comment should be added to guide the AI. A general rule of thumb is that if GPT-4 cannot comprehend the code, it may be too complex for the next developer. However, Code-Narrator is constrained by GPT-4's 8192-token limit, which can be problematic for extensive code files. Those with access to the gpt-4-32k variant should expect better results. Upon its first run, Code-Narrator creates a configuration file by analyzing your project, and then prompts you to review it for accuracy. The key configuration aspects include the "include," "config_files," and "source_path" settings. In its second run, Code-Narrator generates documentation for your entire project. The process is time-consuming, taking approximately 45 minutes to complete from scratch. However, the tool is: - Flexible, allowing for the creation of custom pages such as How-To guides, tutorials, FAQs, READMEs, and other bespoke content. - Multilingual, supporting 25+ languages (as many as GPT-4 supports). - Versatile, capable of generating documentation in various formats (LaTeX, HTML, with the default being Markdown). For a demonstration on transforming a few lines into a How-To guide, watch this video: https://www.youtube.com/watch?v=uJtVCUOTkvw . Remember that brevity is key, as the more concise the input, the more GPT-4 can contribute. Code-Narrator also supports custom plugins, with tutorials available at https://ift.tt/TuoNQHO... . In terms of size and cost, Code-Narrator consists of 45 files and 1712 lines of code. The total cost of generating documentation for the entire project is approximately $2.5, a significant savings compared to manual documentation. During the development of Code-Narrator, I noticed several benefits: - Improved function naming: Reading the generated documentation led me to revise vague or overly general function names, resulting in better code and documentation. - Concise input: Focusing on reducing the size of the input file (liquid) became a fun challenge, helping to optimize the process. - Enjoyable interaction: Working with ChatGPT proved more enjoyable than manually writing documentation, and the more I experimented, the better the results. - Minimal input for tutorials: I was pleasantly surprised by how little input was required to create How-To guides and tutorials using GPT-4. - Encouragement to refactor: The 8K token limitation may be restrictive, but it also encourages developers to refactor their code for improved readability and structure. As a prototype and proof of concept, Code-Narrator has some limitations. I'm excited to see where Code-Narrator goes from here, and your feedback is invaluable. Thank you for taking the time to explore this project! https://ift.tt/6nbqjS9 April 28, 2023 at 03:49PM

Track Work Through the Years

Track Work Through the Years
By Jeremy Menzies

San Francisco’s unique rail system brings together 150-year-old cable cars, historic electric streetcars of all shapes and sizes and modern light rail vehicles.  

Many trades across the SFMTA play a critical role in keeping the system moving. This month we look back in time at the work of one such group, the Track Department. While the lines and technologies of SF’s street railway have changed over the years, some of the base-level work, tools and skills needed to maintain our tracks are the same today as they were over 100 years ago. 

A decade before Muni was founded, the United Railroads Company (URR) dominated San Francisco’s transit system. URR owned and operated nearly 400 miles of street and cable car track all over the city. To keep this network in service, their track department was fully equipped to handle any possible construction or repair job. 

All hands were on deck for this job outside the Ferry Building in 1912. Here, two special work streetcars equipped with cranes lift an entire section of track in one piece. 

The Municipal Railway was built in 1912 and expanded over the next 16 years to include multiple lines and two dedicated tunnels. The city relied on its own team to maintain this system on a daily basis.  

Following World War II, many streetcar lines were converted to bus routes, but Muni retained the J, K, L, M, and N streetcar lines. With those core lines still in service, the work of the Track Dept. continued. 

Taken on January 31, 1947, this photo shows Muni track workers Pat Kellerher and Con Maloney at Division and Bryant Streets.

In the 1970s, construction of the Market Street Subway transformed the city’s streetcar lines into the Muni Metro system. Miles of tracks were rebuilt to handle light rail vehicle (LRV) traffic, and an automatic train control system was introduced for subway operations.

In this 1977 shot, a crew replaces K Line tracks on Ocean Avenue just outside Lick-Wilmerding High School.

Today the SFMTA Track Department is primarily responsible for maintaining and repairing our rail infrastructure. Outside of this, they take on other jobs moving cable cars to and from the cable car carpentry shop, hauling heavy equipment in the subway, and supporting the work of the teams that maintain and repair our stations. With the skilled labor, know-how, and equipment to do a variety of heavy jobs, the department plays a critical role in keeping Muni moving.

Whether it’s 1903 or 2023, track work is a team effort. This photo was taken during the March 2023 Fix-It Week when the Track team replaced sections of rail in the Van Ness Crossover.

SFMTA Retires the Orion, First Hybrid Bus in Cleanest Transit Fleet

SFMTA Retires the Orion, First Hybrid Bus in Cleanest Transit Fleet
By Clive Tsuma

San Francisco’s first low-emissions electric hybrid Orion bus

Muni’s Orion hybrid buses are headed for retirement as we phase in a brand-new batch of El Dorado hybrid electric buses. It’s the end of an era for San Francisco’s first low-emissions electric hybrid fleet that travels the city’s toughest routes.

Orion hybrid fleet tackles Muni’s toughest routes starting in 2007

The Orion buses have been a testament to the SFMTA’s commitment to the latest green transportation technologies. Muni, which previously had relied on a diesel bus fleet in coordination with our electric trolley bus fleet, transitioned to its first 30-foot Orion diesel hybrid-electric buses in 2007. This was the start of the SFMTA’s addition of these lower emission vehicles to one of the greenest fleets in the country, ensuring better air quality city wide.

The Orions brought the agency closer to achieving its goal of an all-electric fleet and a carbon-neutral San Francisco by 2040. This is consistent with San Francisco’s Climate Action Plan to dramatically reduce harmful emissions in communities. 

The Orions’ pint size made them ideal for winding routes like the 36 Teresita, which weaves through Twin Peaks, Diamond Heights, Glen Park and Bernal Heights. Many riders have taken Orions on their adventures along San Francisco’s curving streets, steep hills and tight turns. One can only imagine their sentimental value, especially among those who frequent the 36, as well as the 35 Eureka, 37 Corbett, 39 Coit and 56 Rutland routes.

The Orions were among the first low-floor hybrid buses to serve San Francisco, and the first with closed-circuit security cameras to help keep Muni riders safe. Their interior was fitted with internal destination signs to help customers know when their stop was approaching. The 30-foot coaches were designed to accommodate easier boarding and provide quieter, more efficient operation.

Their arrival offered us an opportunity to train Muni mechanics on hybrid vehicle maintenance. The agency continued to maintain the fleet even after the Orions’ assembly manufacturer went under in 2012.

The new El Dorados are primed to fill the gap left by their predecessors. Like the Orions, they are low-floor buses with a short wheelbase, making them ideal for navigating San Francisco. 

As their taillights fade into the horizon, the Orion hybrid bus fleet takes a much-deserved place in the history of San Francisco transit. They conquered the winding hills of Glen Park and navigated the twisting turns of Telegraph Hill. They will be remembered as the first of Muni’s fleet to pioneer hybrid batteries, moving Muni closer to a zero emissions future.

Muni Improvements Draw Increased Ridership

Muni Improvements Draw Increased Ridership
By Kate McCarthy

38 Geary buses zip downtown on new transit lanes that improve travel times for Muni riders.

As Earth Day approaches and we think about how to encourage more people to take non-car trips, recent Muni improvement projects are drawing increased ridership across the city. While Muni ridership downtown has not yet rebounded to pre-pandemic levels, ridership has gone up on Muni lines where we have improved speed and frequency of Muni service. 

Muni is a lifeline for many of our riders: 70% of Muni riders have an annual income of less than $50,000. As we restored and added Muni service after the start of the pandemic, we invested in the routes that serve people who rely on transit and need it most. For example, after we installed transit lanes, increased frequency and re-routed the 22 Fillmore to bring people to their jobs and medical appointments in Mission Bay, ridership increased to 107% of pre-pandemic levels on weekdays and 118% on weekends. 

Since the start of the pandemic, we’ve implemented more than 21 miles of new transit priority lanes, growing our transit lane network (https://ift.tt/Loa96zT) to over 70 miles. These transit lanes are improving travel times for Muni riders across the city. After transit lanes were installed on Mission Street in downtown, travel times on the 14 Mission and 14R Mission Rapid are now 31% quicker. 

Ridership numbers on the 49 Van Ness-Mission also blossomed to 109% of pre-pandemic ridership on weekdays and 114% on weekends after construction on the Van Ness BRT corridor was completed last April. With physically-separated transit lanes and transit signal priority that gives the green light to Muni and Golden Gate Transit buses, riders there are seeing travel times reduced by 35%. 

A similar story has emerged on San Francisco’s busiest transit boulevard — Geary. Like other lines that serve downtown, the 38 Geary hasn’t fully recovered to pre-pandemic ridership levels. But the route did nab a spot in the top 10 highest recovered routes in the Muni system. The 38 Geary’s 36,000 daily riders have recently seen travel time savings of up to 18% since we installed three miles of new transit lanes, bus stop changes and other improvements as part of the Geary Rapid Project. We plan similar improvements on the western end of the corridor as part of the Geary Boulevard Improvement Project.     

Muni riders have noticed that improvements to our busiest Muni lines are making service faster and more reliable than it has been in decades. Two-thirds (66%) of Muni riders who took our Annual Muni Rider Survey last fall rated Muni service as “good” or “excellent” — a 9% increase from 2021 and the strongest increase since 2018. 

These improvements can’t come soon enough. Most of San Francisco’s greenhouse gas emissions come from cars and trucks. As the urgency to address climate change mounts, so does the need to get the most out of our Muni system. To inspire riders to come back to Muni, we’re working hard to bring back the Muni system our city deserves: One that is thriving with the better frequency, improved reliability and better connections that these projects are delivering.

Show HN: InsightFlow Hey everyone, sharing InsightFlow, a (long) weekend project I made using GPT4. I am bit anxious sharing it since I barely knew how to code in Python before but I was simply amazed on how much GPT was able to help me write something that actually works (I hope). My goal was to create a library that empowers people to ask questions from their data, regardless of its source. InsightFlow does just that, it has some modules that allow s parsing information existing in (for now) video (its audio part), html, and in general text and provides a chat interface on top. I would love to expand this to image and eventually video parsing. I know there are some companies that aim for the same but I could not find an opensouce alternative for it. I tried making it modular so different modalities can be added later on. https://ift.tt/YseDTb7 April 20, 2023 at 06:22PM

Show HN: Database for analyzing US companies, visualize using Apache SuperSet My main motivation was that I wanted to be able to drill down and filter across all the available stocks, look at the data for myself, and narrow down on the stocks I am interested based on my own sets of criteria, and make data-driven analysis for my personal investment strategies. I used PostgreSQL as the backend database for ELT data pipelines, and used Citus Data cstore_fdw for columnar compression for the final dataset. All financial data is coming from SEC Edgar, https://ift.tt/gd7hXlJ . I used Python for downloading most of the data. I also run the data load development locally on my home Ubuntu server that I built 5 years ago. I bought 4TB of M2 disks for best database performance, with PRIME B360M-A motherboard and Intel Chip Coffee Lake S. I built the website simply using WordPress, and I run Apache Superset using gunicorn via Apache Webserver reverse proxy. The registration form I had to build myself with PHP and some JavaScript, because it needed to automatically create a SuperSet user upon registration. Otherwise, I would need to input everyone manually. I used Python again for the data integration. Please don't use the database directly as an investment tool, as its in Beta, and the data still needs to undergo heavy data quality checks, please confirm all the numbers yourself, as I provide a link for every company to the SEC filings. https://ift.tt/RAWzv3u April 19, 2023 at 02:46AM

There’s a Community Shuttle Coming to the Bayview

There’s a Community Shuttle Coming to the Bayview
By

A new shuttle to serve Bayview’s diverse communities

A new community shuttle is coming to Bayview-Hunters Point in January of 2024, and we need your help designing it! The SFMTA is partnering with the California Air Resources Board and nine community-based organizations to launch a dynamic service community shuttle that truly meets your needs. A community shuttle has been a long-desired service for this geographically isolated community, and was identified as a top priority in the Bayview Community Based Transportation Plan. This program builds off of previous community shuttle efforts like the Bayview Moves program. To share your voice, take our survey now or attend one of our upcoming community partner events.

A “dynamic service” shuttle is one that doesn’t have a fixed route like a bus line, but instead operates in a “service area.” The shuttle will pick up and drop off riders anywhere within the Bayview area and connect them to hard-to-reach destinations like community centers, regional transit and grocery stores. Combined with Muni service, this program will help Bayview-Hunters Point residents get around more easily while reducing car trips and improving air quality.

A Community Shuttle only works if it is accessible, feels welcoming and gets people where they need to go. That’s why the SFMTA will be working with residents through the summer and fall of 2023 to build a service plan that works for the community.

This is where you come in. We want to know how you might use a shuttle like this. Would you use it during commute hours or on nights and weekends? Would you ride within your immediate neighborhood or to destinations like the 24th Street BART station and SF General Hospital? How long would you wait for a shuttle to arrive? Would you walk to the corner or a block away for a pickup? Answers to these questions will help us build a shuttle that meets your needs.

We want to establish shuttle service that effectively serves the people living in Bayview-Hunters Point today, and the more feedback we get, the better. You can get involved in the following ways:

• Sign up for our mailing list
• Take our shuttle service planning survey
• Attend an upcoming shuttle outreach event
• Attend a Community Congress meeting in the Bayview – details on the project website
• Contact us directly

This program also includes job training, a Community Congress that will provide project oversight, and a Third Street storefront for transit information and services. You can find more information on our Fact Sheet.

Show HN: Magic Happens – let ChatGPT manage your Kubernetes cluster https://ift.tt/ge7lqQ6

Show HN: Magic Happens – let ChatGPT manage your Kubernetes cluster I built this kubernetes operator as a proof of concept this weekend.. It only has a single required item in the spec, a freeform description field. The operator will use chatgpt to generate a spec, then immediately apply it to the cluster. It makes some attempt to correct errors if there's a problem with the syntax. It will leave additional comments, questions or instructions in the status field of the object. I built this in a weekend and it's still quite unrefined. It's in no way production ready, please don't use it for anything real, but it works better than you would think, considering how simple it is. If you're going to use it, run it on a local cluster like 'kind'. Some descriptions to try: * install a redis namespace with a redis cluster and a service in it * create an argocd application in the argocd namespace to install velero. * write a python script that lists all ec2 instances in us-east-1, and run it as a k8s job with the aws credentials already saved in the default namespace.. a somewhat longer description that also worked: given the following spec: --- kind: MagicHappens apiVersion: gptmagic.io/v1 metadata: name: foo spec: description: this is a freeform description field that will be sent to chatgpt to generate kubernetes resources dryRun: false --- Can you create more magic happens resources, each of which describes an argocd application that needs to be created to install a helm chart for one of the standard cluster addons that need to be installed on a cluster for it to be production ready. The description should be be freeform text like the following: "Create an argocd application in the argocd namespace to install istio from the helm chart with all the defaults" or "Create an argocd application in the argocd namespace to install prometheus and grafana, with an ingress enabled for grafana". Be very thorough and included as many apps that might be needed for a prod ready cluster using industry standard CNCF projects if possible. (this produces a list of additional resources for the operator, which the operator then goes on to create argocd applications for -- it also left comments with instructions on one of the resources for how configure it to work with your cloud provider something to note is that since you can run arbitrary containers with arbitrary commands, and chatgpt can write arbitrary code, you don't have to limit yourself to k8s stuff.. if you've got saas credentials on the cluster, you can just tell it to run a python script as a job to do whatever you want. Since most people are cowards, there's a dryRun field that defaults to true, so it only attaches the spec to the object. It is scary how well this works. https://ift.tt/3WKA2nF April 18, 2023 at 12:09AM

Show HN: Let your body be the gamepad Hi HN, I made a keyboard emulator that tracks your body pose and emits the key presses accordingly. My main motivation was to make my kids move more on rainy days. I already made a couple of mini-games using the body pose [1-3], and those were definitely fun to make and play! However, once the kids learned the tricks, they got bored. I could only produce that much content myself, and soon realized that I lack time for churning out games. Finally, I decided to tap into an endless pool of PC games, preferrably simple and less addictive ones like the Gameboy and DOS games. This project has been also inspired by [4], which has been featured on HN recently.

Show HN: TYON, a Simple JSON Alternative https://ift.tt/VjprYQM

Show HN: TYON, a Simple JSON Alternative TYON (typed object notation) is my attempt to address the main frustrations I have with JSON. 1. Key repetition - you can specify the key names once at the start of a list or map, instead of on each object separately. 2. Escaping strings - everything in a string is literal except for " which is escaped as "". This makes writing regexes and multiline text easier without introducing a bunch of different string styles or excess escaping, which I am not a fan of. 3. While not nearly as important as the first two to me, I did reduce symbol clutter when possible. Files are implicitly maps, keys don't require quotes in most cases, and you don't need commas between items. 4. Decoupling syntax and data formats - TYON has recommended formats for interoperability, but none of these are part of the core spec, so tools are equally welcome to just treat everything as a string. The linked repo contains the spec and a cli app that provides formatting, validation, and conversion to JSON. https://ift.tt/Z0fYuPF April 15, 2023 at 03:10AM

Show HN: WikiBinge – discover how all things are vaguely connected (2016) Connect two articles on Wikipedia, but do it the long way. I've always been a fan of the theory of six degree of separation, but it's an overused concept when exploring the Wiki-graph. Instead of showing the shortest path, which in my opinion is "boring" and ends up connecting super-important central articles, I came up with my own method: WikiBinge selects the smaller, less represented articles on Wikipedia. In a WikiBinge path, the underdogs are the kings! How does it work? It's pretty straightforward! Compute PageRank on the Wiki-graph and assign as weight of each edge the PageRank value of the destination node. A WikiBinge path is then simply a shortest path using these weights: the algorithm will then favor paths passing through articles with lower PageRank values. More on the motives to build this here: https://ift.tt/Dewfri0 This is an older project of mine, but it never got much exposure, so I'm humbly submitting it now. https://ift.tt/qlMUR02 April 14, 2023 at 11:18PM

We feature a Terraform-like declarative interface for defining integrations, embeddable UI components for your users to set up and manage their integrations, and a management console for your team to monitor and troubleshoot. We’re launching our docs ahead of our product because we believe that docs are one of the most important things to get right in building a developer product, and we want to get early feedback on it. Looking forward to hearing your feedback in the comments below! https://ift.tt/uq7zs8I April 14, 2023 at 02:38AM

Show HN: Google Analytics alternative with the most generous free tier https://ift.tt/p6JwgSs

Show HN: Google Analytics alternative with the most generous free tier Hi HN, As an indie hacker, the new Google Analytics (GA4) coming motivated me to look for a straightforward alternative that would also be affordable. I had a few basic product requirements and didn’t want to spend too much to replace a free product. There are a lot of great Google Analytics alternatives out there, but the pricing didn’t seem right. As someone who likes to just build things, many of which aren’t businesses yet, it didn’t make sense to pay for options like Plausible and Fathom out of the gate. So I joined with a friend to build Beam Analytics. Beam gives you all the standard web analytics. It also comes with easy to create funnels so you can see how users move through your site. And we have a great proxy for cohort retention that doesn’t need you to log any data with us. It’s cookie-less and GDPR compliant. The free tier is 100k page views per month so hopefully you’ll give it a try. There’s also a Wordpress integration to make integrating with WordPress sites as easy as a single click - https://ift.tt/iveNZ5I . Appreciate your feedback. You can also email us at hi (at) beamanalytics.io or DM me on twitter @TheBuilderJR. https://ift.tt/G43zTDc April 12, 2023 at 07:10PM

Show HN: NeverPrinter – find and use thousands of nearby printers https://ift.tt/RLSCrvQ

Show HN: NeverPrinter – find and use thousands of nearby printers Hi all, My friends and I have created a Chrome extension and we are looking for feedback on whether people find it useful or not. The extension is intended to serve as a home printer substitute for people (like us) who don't want or need their own printer at home. It makes it easy to send documents to nearby office supply / shipping stores for printing and pickup. Installing the extension adds a printer named NeverPrinter to your list of available printers in Chrome. When you print a document with NeverPrinter, a new tab opens allowing you to select which nearby store you want to send the document to. This is the latest iteration in an ongoing project my friends and I have been working on. We would love to hear any positive or negative feedback. You can get the extension by going to the Chrome Web Store and searching for "NeverPrinter." Or you can visit https://ift.tt/hR0QTZH , which will redirect you there. https://ift.tt/W3dgcFN April 13, 2023 at 11:18PM

Show HN: A minimalist net worth tracker for individuals https://ift.tt/3tlJKAO

Show HN: A minimalist net worth tracker for individuals Hi HN, Today I'm launching the Net Worth Tracker by Flow Finance, a beautiful and minimalist Excel template that allows individuals to track their assets, liabilities, income, and spending on a monthly basis. The focus of this template is understanding long-term trends in the incoming and outgoing expenses for an individual—always with a focus on maximising insights while minimising user inputs. This project was created because the alternatives, frankly, are completely overwhelming. A friend of mine introduced me to the FIRE Movement and, after doing deep dives through Reddit, I tried to find templates to help facilitate a financial tracking system of my own. Every template felt like complete overkill: portfolio tracking for shares, mortgage repayment calculators, even a kind of speedometer which moved depending on my savings rate. Clever, no doubt, but unnecessary for my purposes. After years of tinkering and refining what I truly wanted out of this spreadsheet, I realised it was to clearly understand the flows of my finances. This spreadsheet does not attempt to compete with a typical FIRE spreadsheet or tools like YNAB/Mint, it is about capturing the big picture once a month and essentially taking a snapshot of my financial health. I've priced this spreadsheet at $15 which I believe is a fair price for the value you'll see in taking more control over your personal finances, however as an added incentive (and because I am proud of what I've created and would love more people to use it), I'm currently offering a 50% discount to all HN users, who can use the code f3g27mt at the Gumroad checkout. Thank you for your time and I sincerely hope this product can assist you as much as it has for me. I am more than happy to answer any questions you may have so please feel free to comment below or reach out at contact@getflow.finance. Thank you! https://ift.tt/eICUsc6 April 13, 2023 at 04:37AM

Show HN: GPTCache – Redis for LLMs https://ift.tt/pOhekEu

Show HN: GPTCache – Redis for LLMs Hey folks, As much as we love GPT-4, it's expensive and can be slow at times. That's why we built GPTCache - a semantic cache for autoregressive LMs - atop the vector database Milvus and SQLite. GPTCache provides several benefits: 1) reduced expenses due to minimizing the number of requests and tokens sent to the LLM service 2) enhanced performance by fetching cached query results directly 3) improved scalability and availability by avoiding rate limits, and 4) a flexible development environment that allows developers to verify their application's features without connecting to LLM APIs or network.

Show HN: I’m building an autonomous business run by ChatGPT https://ift.tt/tPwOZDW

Show HN: I’m building an autonomous business run by ChatGPT Hey HN!! I just shipped a project called Airfeed: https://airfeed.co/ Here's how it works: 1. You tell it the research topics you're interested in following This can be anything -- LLMs, chatbots, image generation, scaling model inference, small language models, datasets, etc. 2. Every morning, it filters new AI research papers for quality work that is relevant to your configured topics, and sends you an email summary. Here's a sample email: https://ift.tt/8xCNgQj --- As a fun experiment, I've made everything completely autonomous: Every morning, ChatGPT takes care of filtering/processing all research papers & writing each email. --- Why I built this: I think there needs to be a better way for engineers, researchers, and AI product builders to stay up to date on the latest AI research that's relevant to whatever they're working on. For someone building LLMs, this could mean keeping up with research papers covering multiple topics, ex: scaling attention, model architecture, new datasets, new fine-tuning techniques, etc. --- How this is different from other newsletters: This isn't a generic AI newsletter. It's research-focused & personalized, since it only highlights the papers that might be relevant to you (based on your specific topics). I found this to be useful, since a lot of papers are irrelevant and/or low quality. --- When building maroofy.com [1], I would regularly read the latest research papers on everything related to: contrastive learning, vector embeddings, music classification, etc. So, I thought it would be nice to build something that filters/summarizes just the new research papers covering topics I care about, and sends me the top ones in a daily, morning email. Would love any feedback!! :D [1] https://ift.tt/1pfOtFL https://airfeed.co/ April 13, 2023 at 03:22AM

Show HN: GPT-4-powered web searches for developers https://ift.tt/xdJo27W

Show HN: GPT-4-powered web searches for developers Hi HN, Today we’re launching GPT-4 answers on Phind.com, a developer-focused search engine that uses generative AI to browse the web and answer technical questions, complete with code examples and detailed explanations. Unlike vanilla GPT-4, Phind feeds in relevant websites and technical documentation, reducing the model’s hallucination and keeping it up-to-date. To use it, simply enable the “Expert” toggle before doing a search. GPT-4 is making a night-and-day difference in terms of answer quality. For a question like “How can I RLHF a LLaMa model”, Phind in Expert mode delivers a step-by-step guide complete with citations ( https://ift.tt/BJx5Pip... ) while Phind in default mode meanders a bit and answers the question very generally ( https://ift.tt/73y0bjr... ). GPT-4 is significantly more concise and “systematic” in its answers than our default model. It generates step-by-step instructions over 90% of the time, while our default model does not. We’re particularly focused on ML developers, as Phind can answer questions about many recent ML libraries, papers, and technologies that ChatGPT simply cannot. Even with ChatGPT’s alpha browsing mode, Phind answers technical questions faster and in more detail. For example, Phind running on “Expert” GPT-4 mode can concisely and correctly tell you how to run an Alpaca model using llama.cpp: ( https://ift.tt/gWqivlI... ). In contrast, ChatGPT-4 hallucinates and writes a make function for a fictional llama.cpp. We still have a long way to go and would love to hear your feedback. https://www.phind.com April 12, 2023 at 11:14PM

Show HN: GPT–LLM native macOS app with time travel, versioning, search https://ift.tt/9oYTdS2

Show HN: GPT–LLM native macOS app with time travel, versioning, search Hey everyone! I made a Mac app for exploring large language models. It’s fast, small, has a tiny memory footprint. It’s immutable by design with both immediate time travel and automatic versioning as foundational elements. The app is written in Swift and a bit of Rust for the tokenizer. I used SwiftUI for structure and animations and Cocoa for advanced behavior. All storage is SQLite and local-only. You can go through the database as needed and backup it as well. The app has support for variants, which is the `n` parameter in the OpenAI chat completion API—equivalent to the drafts feature in Bard. It shows model- and ChatML-aware tokens and cost, and it dynamically adjusts response length in function of prompt length and context length. It supports hiding runs that are not useful, marking the ones that are notable, and going through the ancestry of the current run. It also has support for examples, as specified in ChatML, conversation names and personal and local-only notes. The full-text search works across all stored text and it has support for `all`, `any`, `prefix` and `phrase` matching; the results are time-ordered rather than ranked for the time being. There are several shortcuts and more are coming so that the app can be used entirely by keyboard. You can export to JSON and all data is exported. The app is sandboxed and notarized. The API keys are stored securely in the Keychain. Next I plan to implement combinatorial runs (mixing multiple values of the same parameter and multiple models as well) and full Markdown support. Currently only OpenAI’s conversational models are supported (GPT 3.5, GPT 4 8K, GPT 4 32K), but I’ll be adding support for local models and custom ChatML endpoints as soon as possible. Give it a try. Any and all feedback welcome! Thoughts and questions as well! William https://thellm.app April 11, 2023 at 11:34PM

Show HN: Skip the SSO Tax, access your user data with OSS https://ift.tt/sXOvDQd

Show HN: Skip the SSO Tax, access your user data with OSS As the former CTO of an Insurtech and Fintech startup I always had the “pleasure” to keep regulators and auditors happy. Think of documenting who has access to what, quarterly access reviews, yearly audits and so on… Like many others we couldn’t justify the Enterprise-plan for every SaaS tool to simply get access to SSO and SCIM/SAML APIs. For Notion alone the cost would have nearly doubled to $14 per user per month. That’s insane! Mostly unknown to people, SSO Tax also limits access to APIs that are used for managing user access (SCIM/SAML). This has proven to be an incredibly annoying roadblock that prevented me from doing anything useful with our user data: - You want to download the current list of users and their permissions? Forget about it! - You want to centrally assign user roles and permissions? Good luck with that! - You want to delete user accounts immediately? Yeah right, like that's ever gonna happen! It literally cost me hours to update our access matrix at the end of every quarter for our access reviews and manually assigning user accounts and permissions. I figured, there must be a better way than praying to the SaaS gods to miraculously make the SSO Tax disappear (and open up SCIM/SAML along the way). That’s why I sat down a few weeks ago and started building OpenOwl ( https://ift.tt/TfLVZHJ ). It allows me to just plug in my user credentials and automatically download user lists, including permissions from SaaS tools. Granted, OpenOwl is still a work in progress, and it's not perfect. At the moment it's limited to non-SSO login flows and covers only 7 SaaS vendors. My favorite part is that you can configure integrations as “recipes”. The goal was for anybody to be able to add new integrations (IT managers and developers alike). Therefore you ideally don’t even have to write any new code, just tell OpenOwl how the new SaaS vendor works. What do you think? Have you dealt with manually maintaining a list of users and their permissions? Could this approach get us closer to overcoming parts of the SSO Tax? https://ift.tt/TfLVZHJ April 11, 2023 at 06:10PM

Show HN: Sym, define just-in-time access workflows in code https://ift.tt/R6gsimA

Show HN: Sym, define just-in-time access workflows in code Hello HN, My cofounder (jon918) and I started Sym three years ago because we were frustrated with how hard it was to manage access to cloud infrastructure. We wanted to build a tool for JIT access that was actually designed for developers. We were wary of tools that tried to accommodate both devs and IT but ended up with usability compromises for both. First, we figured no one wants another web app to log into so we let administrators define access workflows in Terraform and let developers request and gain access via Slack. That seemed to pay off: being code-based was a big plus for our early customers since it let them manage the logic in version control and test in CI/CD. Second, we knew that updating permissions/roles/access was a major source of toil and risk in the world of cloud infrastructure. Have you ever tried to avoid annoying, persistent access requests by setting policies that are a bit more permissive than you’d like? We felt that fully automated just-in-time access + approvals could really help here. But we also knew that a simple approval tool could end up leading to request fatigue - kind of defeating the purpose. So we built an SDK to let you define checks in code (e.g. pagerduty.on_call, okta.is_user_in_group, github.get_repo_collaborators) in order to dynamically route requests or fast-track access when appropriate. This seems to be paying off: users are creating Slack-based approvals in front of different types of risky actions like production access, sensitive queries and triggering Lambdas. We’d love your feedback on our approach so far. Does this make sense to you? Is this a tool you'd use? What would you want to see out of it? To learn more, check out the video that Nick (nmeans (Sym VPEng)) made [1].

Show HN: AI-Less Hacker News Lately I've felt exhausted due to the deluge of AI/GPT posts on hacker news, and have seen similar grumblings. I threw together this frontend that filters out anything with the phrases AI, LLM, GPT, or LLaMa for use until the hype dies down a bit. Before anyone asks, yes I did try to use ChatGPT to help, and while the code it provided was helpful, it needed some heavy bug-fixing. https://ift.tt/CekRWIQ April 6, 2023 at 12:24AM

Show HN: Live coaching app for remote SWE interviews, uses Whisper and GPT-4 https://ift.tt/NMl37dT

Show HN: Live coaching app for remote SWE interviews, uses Whisper and GPT-4 Posting from a throwaway account to maintain privacy. This project is a salvo against leetcode-style interviews that require candidates to study useless topics and confidently write code in front of a live audience, in order to get a job where none of that stuff matters. Cheetah is an AI-powered macOS app designed to assist users during remote software engineering interviews by providing real-time, discreet coaching and integration with CoderPad. It uses Whisper for audio transcription and GPT-4 to generate hints/answers. The UI is intentionally minimal to allow for discreet use during a video call. It was fun dipping into the world of LLMs, prompt chaining, etc. I didn't find a Swift wrapper for whisper.cpp, so in the repo there's also a barebones Swift framework that wraps whisper.cpp and is designed for real-time transcription on M1/M2. I'll be around if anyone has questions or comments! https://ift.tt/OXHI7C1 April 5, 2023 at 05:06AM

Show HN: CartoSVG – create beautiful map visualizations easily This project aims at making the creation of rich interactive maps easy, with no compromise on the visual quality. A goal is also to export the final SVG as lightweight as possible, with no dependency on external libraries, which are usually needed to have interactive maps on a website. Feel free to explore the examples (the “examples” dropdown at the top-right) to explore what is possible to design with CartoSVG. https://cartosvg.com April 5, 2023 at 12:35AM

Show HN: Daba – Turn your JSON into a database https://ift.tt/RV65xEw

Show HN: Daba – Turn your JSON into a database Hi all, I built this tool when I needed a simple LocalStorage-esque database for a client project, and figured others might want something similar. Basically turns your JSON into a query-able, hosted database in seconds. You can read/update/delete JSON files by path, just like you would in Javascript. So, something like get(”users[7].address”) And while we’re at it, I also built a simple file storage service where you upload a file and it gives you the URL back. A lot of my (and other devs friends') side projects will never require more data than a JSON file can handle. Yet we always have to go through the hoops of setting up and using databases meant to handle huge amounts of data. There are many other services that could benefit from the same minimalist philosophy. The idea is to have a bunch of building blocks of different services, and let the developer scale up/down the complexity as they see fit. I'm working on more services for daba (In no particular order: SQLite db?, auth, emails, …) You can use this for any applications where the data can fit in a JSON file. (e.g. Website CMS, blog, portfolio, small mobile apps, internal tools, …). You’ll be surprised at how much data a 20mb JSON file can hold: https://ift.tt/bmkuYS5...

Show HN: Goru, an experimental, Go-inspired concurrency library for Ruby https://ift.tt/uCXrgHh

Show HN: Goru, an experimental, Go-inspired concurrency library for Ruby Hey folks, wanted to show this off and get feedback. Still early/experimental but there are quite a few concepts I'm excited about here. This project came about while writing a program in Go and loving its approach to concurrency. Being a long-time Rubyist I immediately started to think about what similar concepts might look like in Ruby. I set out with two main design constraints: 1. Lightweight: I didn't want routines to be backed by fibers or threads. Having been involved some in the async project ( https://ift.tt/BXTC58i ), I had some experience using fibers for concurrency but was curious if they could be avoided. 2. Explicitness: Routine behavior must be written to describe exactly how it is to behave. I always felt like concurrent code was hard to fully understand because of the indirection involved. On the spectrum between tedium and magical I wanted to err more on the side of tedium with Goru. Goru routines are just blocks that are called once for every tick of the reactor. It is up to the developer to implement behavior in terms of a state machine, where on each tick the routine takes some action and then updates the state of the routine for the next tick. This fulfills both design constraints: 1. Because routines are just blocks, they weigh in at about ~345 bytes of memory overhead. 2. Routine behavior is explicit because it is written as a state machine inside the block. Couple more features worth noting: * Goru includes channels for buffered reading/writing (similar to channels in Go). * Goru ships with primitives for non-blocking IO to easily build things like http servers. Curious your thoughts! https://ift.tt/Bqm2Zay April 3, 2023 at 07:17PM

Show HN: Shhhbb, an SSH BBS Hello all :) I made this BBS for fun and thought you all would enjoy it. It's not perfect, but it's been a fun exercise! see it: https://ift.tt/t4xLWpM try it: ssh -p 2223 shhhbb.com host it: https://ift.tt/P2mL0fz why? Every year I challenge myself in some new way, this year it is to push one project per week. You might recognize my static site generator [0] or my releaser for go [1] from previous posts as one of these weekly projects. If you want to join me in doing this, it's been a blast and I highly recommend it! Maybe we can chat on the bbs about it :) [0] - bearclaw tiny static generator - https://ift.tt/mr5MeQ8 [1] - release.sh release builder for go - https://ift.tt/mr5MeQ8 need: I'd love a few co-conspirators, or even some new friends for the bbs software or the bbs itself. A lofty nice-to-have goal is meeting a few other similarly motivated people to conspire with on a weekly basis. If that's you, drop me a line! goals: I have about half of an admin interface endpoint pushed up, which I'd like to finish. I realized mid-commit that I'd lacked some other material in a previous commit, and in pushing it up, I ended up pushing half the admin feature. Stay tuned for that. I'd also like to implement a feature where I surrender the socket to a new process so I can upgrade the binary without dropping all of the connected users. I'm not sure on the feasibility of this, but all the words fit together, so it'll be tried. https://donuts-are-good.github.io/shhhbb/` April 2, 2023 at 10:10PM

Show HN: Build your own no-code editor with Reka.js https://ift.tt/czq5OGU

Show HN: Build your own no-code editor with Reka.js Much of the complexity surrounding building no-code editors come from architecting the state management system to power such editors: how can we allow end-users to create and edit entire UI components directly from the browser? Reka solves this by providing an AST-powered state system that enables end-users to create UI components that are nearly as complex as ones that developers could write in code; along with an interpreter to efficiently compute an output that could be rendered on the browser. Furthermore, Reka provides additional extensions, such as enabling real-time collaboration via CRDTs; or you could build a custom extension to support additional functionalities such as a commenting system. All that's left is for you to build your own UI abstractions on top of Reka — designing your editor UI/UX and providing easy-to-use buttons/controls for your end-users to mutate the underlying state in Reka.

Show HN: AI Shakespeare https://ift.tt/J3qUBau

Show HN: AI Shakespeare These days thinking of ways to uniquely show off a text to speech model is tough, as there are a lot of them out there. We thought it would be fun for April 1 to show something a bit on the silly end of things -- we trained our TTS model on "Shakespearean" theatrical voices, and used GPT to generate short plays which are then "acted" out. This lets us show the versatility of our model, that we use in more "serious" settings for generating branded voices for particular languages or accents. It should be noted, the dataset is of our own curation; all voice actors were compensated with full knowledge of being used for TTS and were thrilled to be part of a creative project like this. We resample the speaker embedding space to find voices that are different from any one particular actor. https://ift.tt/DwnV36R April 1, 2023 at 02:00PM

Show HN: Coursemate, connect with other self learners Hey Hacker News! My name is Collin, 18 years old and doing a gap year after finishing high school last year. This was my first real project after starting to learn web development around 5 months ago. I came up with this idea as it was a real pain for me to find other people from my country and especially my age, learning and taking online courses about the same stuff online. Lots of these online courses include their own discord communities and forums, but I still found it very hard to connect with other people in there. Thats why I built Coursemate. I would love to get your feedback on it! :) https://ift.tt/7kNvzfY April 1, 2023 at 02:08PM
