Show HN: Peppa PEG – An Ultra Lightweight PEG Parser in ANSI C https://ift.tt/2ZBEsPq

Show HN: Peppa PEG – An Ultra Lightweight PEG Parser in ANSI C After reading the [PEG Parsers series] written by Guido van Rossum, I started thinking writing a PEG Parser in ANSI C. Here are the reasons: - It's FUN. I've made several parser libraries, such as JSON, Mustache, Markdown, and I think I can take the challenge now. - I haven't had any opportunity to work on an Open Source project written in ANSI C. - Having a PEG parser in ANSI C can benefit whoever is developing a parser, as adding C bindings for other programming languages are not too difficult. And after SIX months' development, my project is now kinda feature complete. It's named Peppa PEG and you can find it here: https://ift.tt/3aBmrqW I have learned quite a lot during the journey of creating it, such as gdb, valgrind, cmake, etc. And I wouldn't make it to the end without learning from some awesome projects, such as pest.rs, cJSON, etc. Appreciate any feedbacks! Thank you! [PEG Parsers series]:

Launch HN: MindsDB (YC W20) – Machine Learning Inside Your Database https://ift.tt/2ZuqrTN

Launch HN: MindsDB (YC W20) – Machine Learning Inside Your Database Hi HN, Adam and Jorge here, and today we’re very excited to share MindsDB with you ( https://ift.tt/2UJWtY6 ). MindsDB AutoML Server is an open-source platform designed to accelerate machine learning workflows for people with data inside databases by introducing virtual AI tables. We allow you to create and consume machine learning models as regular database tables. Jorge and I have been friends for many years, having first met at college. We have previously founded and failed at another startup, but we stuck together as a team to start MindsDB. Initially a passion project, MindsDB began as an idea to help those who could not afford to hire a team of data scientists, which at the time was (and still is) very expensive. It has since grown into a thriving open-source community with contributors and users all over the globe. With the plethora of data available in databases today, predictive modeling can often be a pain, e

Launch HN: HiGeorge (YC W21) – Real-time data visualizations for public datasets https://ift.tt/2NGzfTM

Launch HN: HiGeorge (YC W21) – Real-time data visualizations for public datasets Hi HN! Anuj here. My co-founder Amir (Aazo11) and I are building HiGeorge ( https://hi-george.com/ ). We make localized drag-and-drop data visualizations so that all publishers, even the small ones, can better leverage data in their storytelling. Think Tableau with all the necessary data attached. At the onset of the pandemic Amir and I were looking for local data on the spread of the virus. We visited the sites of large national newsrooms like the NYTimes and were impressed by the quality of data visualizations and maps, but they lacked the geographic granularity for our own neighborhood. We then turned to our local newsrooms but found they presented data in tables and lists that made it difficult to comprehend the virus’ spread and trends. We wondered why. After talking to local journalists and publishers, we found that newsrooms simply do not have the resources to make sense of large datasets. Public da

Virtual Parade and New Central Subway Art Ring in Lunar New Year

Virtual Parade and New Central Subway Art Ring in Lunar New Year By Sophia Scherr We are entering the year of the Ox, typically symbolizing hard work, positivity, and honesty. This year the SFMTA will continue the tradition of celebration with the virtual San Francisco Chinese New Year Parade   on February 20th at 6 pm on KTVU. Celebrating Lunar New Year and the San Francisco Chinese community has been a long-standing tradition for many of us. In 1849, San Francisco’s population swelled to 50,000 and many of the new residents were Chinese immigrants, coming to work in gold mines or on railroad lines. By the 1860’s, the Chinese were eager to share their culture with others and the annual tradition of parade and pageantry was born. A variety of other cultural groups throughout the city were invited to participate, and they marched down what today are Grant Avenue and Kearny Street with colorful flags, banners, lanterns, and drums and firecrackers to drive away evil spirits. The city’

Launch HN: Ontop (YC W21) – Easily hire and pay remote workers in LATAM https://ift.tt/3s2MTj0

Launch HN: Ontop (YC W21) – Easily hire and pay remote workers in LATAM Hi YC! We are Santiago Aparicio, Julian Torres and Jaime Abella and we are from Colombia. We are building Ontop (www.ontop.ai) to help companies do remote hiring and payouts, all the way from contract creation, to compliance documentation and easy money transfers. COVID-19 has taught us all that remote works. Our bet is that companies in the US and Europe will start hiring more people in LATAM because talent is increasing in quality at a fraction of price compared to what they can get elsewhere. Paying people in LATAM requires local knowledge to get the level of speed and compliance that workers need to get their money on time. We are building a solution so companies hiring in LATAM have to do less paperwork, can easily be compliant and disperse payments to different countries in a single place. In our previous startup Fitpal (multi gym membership in LATAM) we experienced the pain behind signing contracts, collecti

Launch HN: Datrics (YC W21) – No-Code Analytics and ML for FinTech https://ift.tt/3beSuvY

Launch HN: Datrics (YC W21) – No-Code Analytics and ML for FinTech Hey everyone, we're Anton (avais), Kirill (Datkiri), and Volodymyr (vsofi), the founders of Datrics ( https://datrics.ai ). We help FinTech companies build and deploy machine learning models without writing code. We provide a visual tool to work with structured data by constructing a diagram of data manipulations from lego-like bricks, and then execute it all on a backend. This lets our users accomplish tasks that usually need a team of software engineers, data scientists, and DevOps. For instance, one of our customers is a consumer lending company that developed a new risk model using just our drag-and-drop interface. I used to lead a large data science consultancy team, being responsible for Financial Services (and Risks specifically). Our teams’ projects included end-to-end risk modeling, demand forecasting, and inventory management optimization, mostly requiring combined efforts from different technical teams an

More Muni Metro Rail to Return in May

More Muni Metro Rail to Return in May By Mariana Maguire By May, the SFMTA plans to restart more Muni Metro rail service, extending the T Third Metro rail route between Sunnydale and West Portal, and bringing the full N Judah Metro rail route back into service between 4th and King (CalTrain) and La Playa (Ocean Beach). Adding Metro rail service means we can connect more customers to essential jobs and locations along these routes and make it easier for customers to travel through downtown along Market Street. Since August 2020, Muni has been undertaking intensive subway repairs after discovering some potentially faulty overhead splices and issues with ballast in the Eureka Curve/Twin Peaks Tunnel. We are now moving closer to completing the essential repairs and upgrades which will allow us to reopen subway service. Our work crews have removed all of the splices that had been potentially defective and replaced them with splices from a new manufacturer. We’ve also finished construct

Launch HN: Worksphere (YC W21) – Manage flexible in-office or remote workspaces https://ift.tt/3s2IAnT

Launch HN: Worksphere (YC W21) – Manage flexible in-office or remote workspaces Hey HN, Aakhil, Theresa & Mark here at Worksphere (https://worksphere.com). Our software helps companies manage a safe workplace where employees can work flexibly in-office or remote. Worksphere automates desk reservations, safe entry, and gives companies office usage data to right-size their workplaces. We previously worked together at Lish, a corporate catering marketplace startup catering (pun intended) to tech companies. Last March our revenue went off a cliff. No people in office = no lunch orders. We love our clients and our team, so we got to work on solving a new problem for our primary users - HR, Office, and Facilities Managers. At the start of the pandemic, our users were struggling with how to return to their offices safely. New problems like enforcing social distancing, screening for COVID-19 symptoms, and contact tracing could not be solved at scale with existing tools. New coronavirus wor

Mask Up - It's the Law!

Mask Up - It's the Law! By Kristen Holland You may hear a new announcement on our vehicles or see new messages about masks being required by federal law. The spread of COVID-19 has led the federal government to enact a mask requirement for all public transportation conveyances .  Here in San Francisco, that law means wearing a mask in Muni stations, when purchasing a ticket and while waiting for, boarding, riding or exiting transit. Failure to wear a mask can result in denial of boarding, removal from Muni and may carry federal penalties. Muni customers are doing great when it comes to mask compliance, which consistently exceeds 95% (see chart). You get it. Wearing masks, physically distancing and riding Muni for only essential trips remain crucial to reducing the spread of COVID-19. The SFMTA mask survey for the final week of January 2021 reported 97% compliance And every week, our operators, fare inspectors and ambassadors hand out thousands of masks to those who don’t ha

Launch HN: June (YC W21) – Two-click analytics reports on top of Segment data https://ift.tt/3aqZxlX

Launch HN: June (YC W21) – Two-click analytics reports on top of Segment data Hi HN! I’m Ferruccio, cofounder of June ( https://june.so ). We make it easy to set up dashboards for your most important product metrics. After a couple of years working in product teams, we realised that most companies measure the same things. So we created a set of templates that help you streamline the process of getting an insight from your data. With Amplitude/Mixpanel you have to know what you should be measuring and how. Getting to an insight starts from a blank canvas, is intimidating, and requires some expertise. With June, you pick a template, connect Segment, select the right events for your analysis, and get a report. We currently have 9 templates including Retention, Active Users, and Churning Users. We release a new one every week. We’re also starting to allow you to create and share your own templates. To try it out, go to https://ift.tt/2N59oVQ and pick a template you’d like to try. Connect y

Launch HN: Noya (YC W21) – Direct air capture of CO2 using cooling towers https://ift.tt/37jqZjH

Launch HN: Noya (YC W21) – Direct air capture of CO2 using cooling towers Hello HN! I'm Josh, one of the co-founders of Noya ( https://noyalabs.com ). Noya is designing a cheaper process to capture CO2 directly from the atmosphere. We do this by retrofitting industrial cooling towers owned and operated by other companies to perform carbon capture. We then sell the captured CO2 to companies that need it, and pay a piece of the proceeds to the companies that own the cooling towers. As the wildfires in California became worse and worse, my co-founder (and roommate at the time) Daniel and I became increasingly concerned that we weren't doing enough to be a part of the solution. The more that climate catastrophes became the norm, the more we became obsessed with one seemingly-simple question: If climate change is caused by having too much CO2 in the sky... can't we just reverse it by yanking CO2 out of the sky? Humans have known how to scrub CO2 out of gas mixtures for almost a

Launch HN: Pyroscope (YC W21) – Continuous profiling software https://ift.tt/2Zhzo2L

Launch HN: Pyroscope (YC W21) – Continuous profiling software Hi HN! Dmitry and Ryan here. We're building Pyroscope ( https://pyroscope.io/ ) — an open source continuous profiling platform ( https://ift.tt/2L1jeqC ). We started working on it a few months ago. I did a lot of profiling at my last job and I always thought that profiling tools provide a ton of value in terms of reducing latency and cutting cloud costs, but are very hard to use. With most of them you have to profile your programs locally on your machine. If you can profile in production, you often have to be very lucky to catch the issues happening live, you can't just go back in time with these tools. So I thought, why not just run some profiler 24/7 in production environment? I talked about this to my friend Ryan and we started working. One of the big concerns we heard from people early on was that profilers typically slow down your code, sometimes to the point that it's not suitable for production use at all.

Show HN: Save 6 months to deploy your apps on AWS in 30 minutes https://ift.tt/2OC9NPU

Show HN: Save 6 months to deploy your apps on AWS in 30 minutes I am Romaric, CEO of Qovery (https://www.qovery.com) (Techstars Paris 2019). As an early-stage startup, I know how it can be painful to stay focus on our business. Especially when it comes to putting our apps online, that's precisely why, with my team of 7, we have created Qovery to help any company to deploy their apps on AWS in 30 minutes instead of months (no joke). We're still early stage, but: 1. More than 1200 developers and 10 companies are using Qovery . 2. We are financially backed by the co-founders of Datadog, Docker, PeopleDoc, and Contentsquare . Take a look at this article to see how you can get started ( https://ift.tt/3acBO7y ). Today, we support AWS and Digital Ocean, we expect to support GCP and Azure in the coming weeks. About the co-founders: Pierre and I (Romaric) were working as SRE for Ullink, Red-Hat, Criteo, Sirdata for 10 years. Basically, we always were helping developers to deploy their
