Show HN: Make catch-ups happen in different time zones https://ift.tt/gFNA0L7

Show HN: Make catch-ups happen in different time zones https://ift.tt/dSDceX7 We (Sinan and Maciej) started off like any couple of young guys after a few drinks, setting ourselves a goal to “Change the World”. Except the next morning we were still determined to chase this goal. So to try and figure out how we were going to change the world, we said to each other: “Let’s Ketchup”. So we decided to “ketchup” regularly with the goal to change the world. We set ourselves some rituals and commitments as part of our ketchup (mainly just for fun, first). Over time, we iterated on our process and our ketchup developed and evolved. Now, after 3017920 minutes (over 40 “ketchups”), AND each of us moving countries/timezones multiple times. We always made it happen We always made it meaningful In the last year and a half, we have also started having regular ketchups with other groups of friends with different goals, some as simple as “just to stay in touch”. And again, we have found that with these...

Show HN: Colorfle – A daily color mixing game inspired by Wordle https://ift.tt/yFuIV7l

Show HN: Colorfle – A daily color mixing game inspired by Wordle Hi HN, I was inspired by Wordle to make Colorfle, a different take on the genre where the goal is to mix colors together to match the target color within six tries. There were some interesting problems to tackle in making this game, one of them being the difference between mixing digital colors and real-life behavior (in RGB, blue + yellow = grey!). I hope you enjoy it -- any feedback would be much appreciated! https://colorfle.com/ April 29, 2022 at 04:50PM

This Day in History: McAllister Street 1909

Image
This Day in History: McAllister Street 1909 By Jeremy Menzies Here’s a look back to April 29,1909 with two photos showing an important change to McAllister Street in the Western Addition. McAllister has been served by a transit line since at least the 1880s. Beginning with a cable car run by the Market Street Cable Railway, McAllister served as an important part of the city’s east-west transit system.  These two photos show construction work to remove the old cable car tracks and replace them with electric streetcar rails: Laborers dig cable car “yokes” out of the street on McAllister between Scott and Pierce streets. Yokes are heavy steel frames that support both the rails and the cable channel on a cable car trackway. Prior to the 1906 Earthquake and Fires, San Francisco’s transit system was largely made up of cable car lines, which made navigating the steep hills easy. However, the cable cars were slow and costly to operate compared to newer electric streetcars.  Foll...

Show HN: WeakVim, My attempt at a modular, transparent starter kit for Neovim https://ift.tt/aD4Z6UT

Show HN: WeakVim, My attempt at a modular, transparent starter kit for Neovim Hi all, I _love_ Neovim. However, I think many parts of it could be easier to configure or understand, especially when it comes to LSPs. There's a ton of plugins that fill the gap, but some of them are sparse in documentation. There's also distributions like LunarVim that attempt to add a Doom Emacs-like layer above. My approach is a bit different, simply giving an opinionated, modular, and documented configuration that an interested user can easily modify to their needs. It makes use of the most helpful plugins I've encountered to create the best experience I could muster while retaining an air of simplicity. I hope this is helpful to someone out there! https://ift.tt/ykR8OzY April 29, 2022 at 02:03AM

SFMTA Recently Approved Budget Serves San Francisco

Image
SFMTA Recently Approved Budget Serves San Francisco By Stephen Chun Delivering on Your Service Priorities  The Fiscal Year (FY) 2023 & 2024 SFMTA Budget was passed by the SFMTA Board of Directors last week. It will be submitted to the Mayor’s Office by May 1, and the mayor will then send the budget to the Board of Supervisors on June 1.   This budget cycle, we approached outreach as a city-wide listening session. Rather than presenting a pre-set budget to our stakeholders, customers and the wider community for feedback, we focused on soliciting feedback and then crafted our budget to address the top community priorities.  Community Survey Highlights  Surveys were offered in English, Chinese, Spanish and Filipino both online and in print. They included an open-ended question to ensure San Franciscans had a real opportunity to provide specific feedback about service priorities.  1,295 responses from online and paper surveys in four languages...

Show HN: Lists.sh – A Microblog for Lists Greetings, creator here! I've been working on a new blogging platform specifically for lists on and off for a few months now and I'm excited to officially announce its launch. After seeing https://charm.sh a few months ago, I've been enamored by the idea of SSH apps. I decided that a blogging platform focused on developers could be the perfect use case for an SSH app. Also, I love writing lists. I think restricting writing to a set of lists can really help improve clarity in thought. The goal of this blogging platform is to make it simple to use the tools you love to write and publish lists. There is no installation, signup is as easy as SSH'ing into our CMS, and publishing content is as easy as copying files to our server. Check it out and let me know what you think! source: https://ift.tt/bis4pcR https://lists.sh April 25, 2022 at 03:44PM

SFMTA Announces New Initiative to Address Safety

Image
SFMTA Announces New Initiative to Address Safety By Kimberly Burrus SFMTA staff celebrating women’s history Safety is an absolute priority for the SFMTA. We’ve heard loud and clear that personal safety is a growing concern for the public and staff and we’ve taken a lot of steps to increase safety across our system. We also know there is much work to do to address some of the most pervasive ways harassment and violence show up in public transportation.   This April as we observe Sexual Harassment Awareness Month, the SFMTA is proud to announce that we are developing a new Safety Equity Initiative. The goal of the initiative is to reduce and eventually eliminate gender-based harassment and violence on Muni.  Gender-based harassment is one of the most widespread and persistent forms of violence. It impacts women, girls and gender-expansive people — people who don’t conform to traditional gender roles — of all ages, abilities, races, ethnicities, and cultural and langua...

Show HN: A tool to seed your dev database with real data https://ift.tt/ocHyJkp

Show HN: A tool to seed your dev database with real data A bunch of developers and myself have created RepliByte - an open-source tool to seed a development database from a production database. Features: - Support data backup and restore for PostgreSQL, MySQL and MongoDB - Replace sensitive data with fake data - Works on large database (> 10GB) (read Design) - Database Subsetting: Scale down a production database to a more reasonable size - Start a local database with the prod data in a single command - On-the-fly data (de)compression (Zlib) - On-the-fly data de/encryption (AES-256) - Fully stateless (no server, no daemon) and lightweight binary - Use custom transformers My motivation: As a developer, creating a fake dataset for running tests is tedious. Plus, it does not reflect the real-world data and painful to keep updated. If you prefer to run your app tests with production data. Then RepliByte is for you as well. Available for MacOSX, Linux and Windows. > https://ift.tt/3pf...

Show HN: M3O – Universal Public API Interface https://ift.tt/hgDRI6H

Show HN: M3O – Universal Public API Interface Hey all, I'm Asim Aslam, the founder of M3O, a curated catalog of APIs that provides simple abstractions for the most common API use cases. The idea is to create a single place to explore, discover and consume public APIs as higher level building blocks. Most of the time I don’t use all the features of an API and I assume most devs don't either, so picking and choosing the common patterns, abstracting it away and surfacing a new building block is useful. For example, Twilio has a lot of APIs but I only care about SMS. Even then I just want a quick way to send it. So stripping it all away results in something that's one endpoint and 3 fields (from, to and message). Another example is something like email. There are services like sendgrid that provide a really feature rich experience for email but I’m just looking for something simple that will let me send plain text or html. There are a number of API marketplaces out there, but w...

Show HN: I'm making a dynamic language in Rust https://ift.tt/JIxRljO

Show HN: I'm making a dynamic language in Rust https://ift.tt/lfAdGk3 An implementation of a dynamic programming language in Rust. Includes: Parser/Compiler, REPL, Virtual Machine, Bytecode Disassembler This started out as a learning project to teach myself Rust. It has grown into a decently substantial piece of software and I've learned quite a bit in the process! Some neat things: + A garbage collector that can store dynamically sized types without any double-indirection (i.e. I have my own Box implementation with manual alloc/dealloc) + The smart pointer used to reference GCed data is a thin pointer. The ptr metadata needed for DSTs is stored in the GC allocation itself, so that the GC smart pointer is just a single usize wide. This allows me to keep the core value enum Variant down to 16 bytes (8 bytes for data, the enum discriminant, and some padding). + The GC also supports weak references! + Statically dispatched type object model using a newtype wrapper and Rust's d...

Show HN: This AI Does Not Exist Hey HN! Author of the site here. I tried a few tricks to keep the text-generation part of the site up, but even leaning hard on Huggingface's API and bumping time-outs up, it looks like the site is struggling a bit. I'm going to see if there's anything I can do to keep the text-generation part available, but in the meantime, the pre-generated set should stay pretty stable. Not sure if there's much else I can do without burning a hole in my cloud bills — sorry for the troubles! I've put up a more detailed description of how this works on the GitHub - https://ift.tt/a73uW4p PS - if anyone at Huggingface is reading this and wants to help out with keeping the API up, that would be super :) https://ift.tt/qDdKmoZ April 23, 2022 at 09:04PM

Show HN: A better Reddit search engine to find Menswear recommendations https://ift.tt/cpzxXC1

Show HN: A better Reddit search engine to find Menswear recommendations Hey HN Community! We built this simple community search tool that basically allows people to search through thousands of past Reddit threads and tens of thousands of recommendations using tags. It mostly covers a few bigger subreddits like r/BIFL, r/MFA, r/AskMen, r/SkincareAddiction but along the way, I expanded it to include other smaller subreddits too. In addition to filtering by category, power users can also search by -Body Fit (big thigh, long torso) -Occupation (work in retail, teacher, doctor) -Age (18-24, 25-35), Size (height, weight) -Brand comparison (similar to: X) -Use (suitable for wedding, everyday wear) -Location (available in UK, use in Northeast US) -Mood/Style (minimalist, vintage, retro) Check it out.

Show HN: [Experimental] Fleet – A build tool for Rust that's upto 5x faster https://ift.tt/7mqUjcS

Show HN: [Experimental] Fleet – A build tool for Rust that's upto 5x faster Fleet is an experimental fast, lightweight, open-source, build tool for Rust. Builds with Fleet enabled are up-to 5x faster! For a production repository (infinyon/fluvio) which we tested, we were able to cut down our incremental build times from 29 seconds down to 9 seconds, boosted by Fleet. We saw even better results on dimensionhq/volt, with our build times cut down from 3 minutes to just 1 minute - a 3x speed improvement! How does fleet work? Fleet works by optimizing your builds using existing tooling available in the Rust ecosystem, including seamlessly integrating sccache, lld, zld, ramdisks (for those using WSL or HDD's) et al. You can get fleet at the official website. Check out fleet over at https://ift.tt/mYD2KzX and our website at https://fleet.rs Looking forward to your feedback and thoughts! April 23, 2022 at 11:31AM

Show HN: A programmer's approach to finding gifts https://ift.tt/sJbmHkC

Show HN: A programmer's approach to finding gifts Hey Folks, I’ve been really annoyed with the search part of finding gifts. It’s hard to use keyword search for something when it’s an “I’ll know it when I see it” kind of deal. So I thought, what if we scraped/indexed TONS of products and then just focused on removing the things we don’t want and then see what’s left to see if there’s anything cool? I built it in Flutter so it's both iOS and Android but it could be web too. I’ve only just started the scraping/tagging of products and if anyone has suggestions for bulk tagging images/content I would love to hear them. That’s the current bottleneck. Any feedback would be welcome! cvanvlack AT gmail DOT com if you want to discuss 1-on-1. https://ift.tt/JWrFKwZ April 22, 2022 at 12:35PM

Show HN: I built an app to help with Windows container networking https://ift.tt/cukRSE0

Show HN: I built an app to help with Windows container networking I've been playing with cross platform windows/linux Kubernetes clusters recently and have had endless problems with installer scripts misconfiguring networking by using the wrong NIC etc. I got frustrated with the tooling on windows to debug container networking so I built a tool that attempts to stitch together the HNS (Host Network Service) & HCS (Host Compute Service) resources into a tree that shows the relationship between configs. You can also search over it to find the networking impacting your containers or launch the windows built in packet capture tool to create a network trace you can open in Wireshark for analysis. I'm not a desktop app developer so it's pretty rough around the edges and I've only really tested on Windows 11 and Server 2019. https://ift.tt/drkhnex April 22, 2022 at 08:38AM

Show HN: Two-way Jira sync in a collaborative spreadsheet and Gantt https://ift.tt/A62vQqy

Show HN: Two-way Jira sync in a collaborative spreadsheet and Gantt Hello HN, Our startup nearly died 2 years ago. We kept losing customers to spreadsheets. And it made us see a problem right under our nose: everyone just wanted flexibility & speed from a spreadsheet. But they have to stay in sync with {Jira / Salesforce / insert SaaS app}. When we followed this thread, we discovered how broken the integration experience was for flexible products like Airtable, Smartsheet, Monday, and Google Sheets. Their big problem is that they transform external data into their own format. This makes setup harder, since you have to get the mapping just right. And often you can’t sync back. We took a different path when building Visor. We essentially made a data lake & ETL tool with a front-end. Visor integrates with your Jira instance, reads its schema, helps you import the right data, and lets you work in a flexible spreadsheet* that syncs both ways. There’s also an interactive Gantt & ...

Show HN: JavaScript as a Database – Serverless Platform Hi HN! I’d like to share with you my project: JSDB. Two months ago I had this thought while reviewing a PR on a web application. What if I didn’t have to write code to communicate with my backend or database? It would be fun to just use arrays and objects like you normally do in javascript and have things magically save. That weekend I hacked together something that used proxies and classes to ‘magically’ send data to your backend when you assign or access properties in an object or array. Using the same API you already know. This means you can save data like this: items[x] = {a:2,b:false} and read data like this: console.log(await items[x].a) or console.log(await items.find(o => o.a === 2)) While sharing it with some devs I started to get comments like this? “Wow that’s super simple. Is it secure?” So I started building a platform around this idea. A platform that allows javascript developers to write full stack applications, ...

How People Traveled Through San Francisco in 2021

Image
How People Traveled Through San Francisco in 2021 By Maia Moran Earth Day is April 22 and a great time to think about changes we can make in our own lives to support the health of our planet. When it comes to climate change, one of the most meaningful actions we can take is to drive less and get around more by biking, walking and taking forms of public transportation like Muni. Transportation is the largest source of greenhouse gas emissions (GHG) in San Francisco, with personal driving accounting for 72% of the sector’s emissions. By comparison, Muni accounts for about 1% of GHG emissions in and out of the city.  But when it comes to driving less, the San Francisco Bay Area is going in the wrong direction. Public transit use fell by 11% between 2019 and 2021 and private automobile use increased by 13%, according to the results of the 2021 Travel Decision Survey. That’s why we’ve been working so hard to make transit, walking and biking more appealing and convenient with new tran...

Show HN: Employees.fyi – Easily compare U.S. workforce demographic data Hi HN! We built Employees.fyi to make it easy to compare U.S. workforce demographic data across companies and against industry reference data. In the U.S., the Equal Employment Opportunity Commission (EEOC) requires the collection and submission of demographic workforce data. We collected and organized the publicly available federal data from the EEOC as well as publicly available EEO-1 submissions from individual companies. By doing so, we hope to make it easy to compare U.S. workforce demographic data across companies and against industry reference data. The URL contains your current selection.

Show HN: A small Hypercard stack running as a PWA In my early programming years, I went from BASIC to HyperCard, then learned C when I couldn't make HyperCard do everything I wanted. Plenty of folks have pointed out how the lack of native support for color doomed HyperCard. But I think it was really over when the web got started and replaced everything in the "personal content" space from underneath, so I decided to see if the idea of HyperCard would work as a web app. There are some missing pieces -- it's not perfectly compatible. You can, however, make stacks online and let others see them. Free, no ads, no personal information, you are not tracked, just a fun project. https://ift.tt/BtEg8xZ April 15, 2022 at 05:19PM

Show HN: Programmatic – a REPL for creating labeled data Hey HN, I’m Jordan cofounder of Humanloop (YC S20) and I’m excited to show you Programmatic — an annotation tool for building large labeled datasets for NLP without manual annotation . Programmatic is like a REPL for data annotation. You: 1. Write simple rules/functions that can approximately label the data 2. Get near-instant feedback across your entire corpus 3. Iterate and improve your rules Finally, it uses a Bayesian label model [1] to convert these noisy annotations into a single, large, clean dataset, which you can then use for training machine learning models. You can programmatically label millions of datapoints in the time taken to hand-label hundreds. What we do differently from weak supervision packages like Snorkel/skweak[1] is to focus on UI to give near-instantaneous feedback. We love these packages but when we tried to iterate on labeling functions we had to write a ton of boilerplate code and wrestle with pandas ...

Show HN: MetricFlow – open-source metric framework Hi HN community, I’m Nick, co-founder/CEO of Transform.co. I’m thrilled to share MetricFlow, an open-source metric creation framework: https://ift.tt/GCZOLe2 MetricFlow strives to make what has historically been an extremely repetitive process, writing SQL queries on core normalized data models, much more DRY. MetricFlow consolidates the definitions for joins, aggregations, filters, etc., and programmatically generates SQL to construct data marts. You can think of it like LookML, but more powerful and ergonomic (and open source!). The project has three components: 1. MetricFlow Spec: The specification encapsulates metric logic in a more reusable set of abstractions: data_sources, measures, dimensions, identifiers, metrics, and materializations. 2. DataFlow Planner: The Query Planner is a generalized SQL constructor. We take in data sources (ideally normalized data models) and generate a graph of data transformations (a flow, if you wil...

Show HN: ProductDiv – A Website Editor for Developers I've been working on a library for developing websites visually. There are many tools for building websites, but none that fit my workflow as a front-end developer, so I made my own!

ProductDiv is developer-first, meaning the configuration for the editor lives in your source code. You can evolve the configuration as your project grows (as it inevitably will!). This lets you standardize design patterns and makes it easy to distribute high quality components to your team.

Show HN: Bloben – self hosted web CalDAV calendar client https://ift.tt/ltuDj9A

Show HN: Bloben – self hosted web CalDAV calendar client Hello all, I have been working on a self hosted CalDAV calendar client Bloben https://ift.tt/DNUmnVZ This is mostly an alternative to other web clients like great AgenDAV with some additional features I wanted to use like email invites, alarms, webcalendars, etc. You can play with demo (limited to read access) here: https://ift.tt/bMsH3Bc In the end it should provide separate clients also for CalDAV tasks and notes. One thing I would maybe like to discuss more is adding encryption, which is obviously quite problematic when using standards like CalDAV. Initially I just added non-compatible fully encrypted calendars, but realised this might not be useful for many people using different clients. Something halfway is adding an option to protect only some, say sensitive, events by encrypting fields like title, description or location. That way events will still be displayed via standard mobile apps and decrypted only in Bloben client ...

Show HN: A tiny solar-powered server only awake during the day https://ift.tt/nMcCLye

Show HN: A tiny solar-powered server only awake during the day Solar Witch is a little webpage and server which receives and displays messages, so I suppose it's a tiny message board. It's coded in very dubious Arduino C. It's not a 24/7 website. Depending on the state of the battery, the server itself might run all night, but all the messages it receives during the day are deleted at sunset, and the messaging function itself is only active between sunrise and sunset. This is for two reasons: 1. Less usage of Solar Witch during the night conserves battery power. 2. I like the idea of websites which _aren't_ constantly available. Websites which have to sleep too. Websites living on servers which aren't somewhere in the cloud, but which are bound to a particular location, giving you a sense of where in the world they actually live. Solar Witch is very much inspired by the solar-powered version of Low Tech Magazine ( https://ift.tt/uIsQy6V ), but at a far, far smaller ...

Show HN: Host Touchless Menus for Free https://ift.tt/PKBCcin

Show HN: Host Touchless Menus for Free Many restaurants moved to touchless menus during the pandemic. The restaurant owners need a solution to host their existing digital menus (in PDF) online and give QR codes to their customers. When customers scan the QR codes, they can view the menus on mobile and order in person. I built a website for this simple use case last night. I'm planning to get first 100 users and validate product market fit in next few weeks. The basic functionalities will always be free. I probably will be able to monetize by offering tracking and analytics. I don't know if there is a strong need for ordering food on mobile. Some restaurants certainly do this. However heavy automation in the ordering process creates a different dining experience which may not fit all restaurants. I'm not a frontend engineer by any means. The UI is very primitive. I can also open source the project if there's any interest. https://ift.tt/RAw4H9z April 2, 2022 at 02:51AM
