Show HN: Browser Extension to make a language test out of any website https://bit.ly/2NTL09z

Show HN: Browser Extension to make a language test out of any website I was preparing to German C1 recently and my vocabulary was the bottleneck. I didn't want to read boring materials and do boring exercises. Instead I noticed that there are sites in German, which I naturally enjoy. So I just made an extension to make language tests out of them. The approach is the following: 1) Open an interesting webpage in your target language. 2) Select text. 3) The extension replaces some words with gaps. 4) Read the text, fill in the gaps. Obviously just typing random words out of the blue can be overwhelming, so there is a mode to drag&drop words from a list into the correct places. I personally see this as active reading. My brain not only consumes information, but always try to guess the word from the context. I suspect that this helps with active vocabulary (i.e. to actually use the new words in writing). In the end I passed C1 exam (obviously I did other preparations too, not only this extension). This is a beta version for now and it is 100% free: Chrome: https://bit.ly/3qTIuPi Firefox: https://mzl.la/3aTaxsI If you didn't enjoy my explanation skills, there is an example video here: https://bit.ly/2ZPAMd6 I would love to hear whether you find this useful and your ideas how I could improve it. I might add payed features eventually to help developing the extension further, but I don't know a good mechanism to do this. I understand that 1$ in the US is very different from 1$ in e.g. India. I want this extension to bring value to everyone independently of their location and financial state. My current plan is to have the base version (i.e. like now) always free, since this already provides majority of value. Curious to hear your thoughts. February 25, 2021 at 09:41AM

Show HN: Summarize IPs (bulk geo, asn, privacy report for IP addresses) We recently launched a free tool that shows a summary of the top cities, countries, asns, routes and much of the other context that we (IPinfo) have for any IP addresses you paste into it. Sample results: https://bit.ly/2MovSAI You can paste any arbitrary text into the tool at https://bit.ly/3uvmMDi and we'll extract the IPs. It can be useful for getting a quick summary of a set of IPs (eg. click on first google result for "public proxies", copy and paste the results into the tool, and see where the proxies are located, and the networks they're on), for investigating issues (eg. your website gets a large spike of traffic, paste the recent IPs from your access log into the tool and see if there's a specific network that stands out), threat investigation, debugging and more. We're planning to add more functionality and data points in the near future, and any feedback or suggestions are very welcome! February 24, 2021 at 05:16PM

Launch HN: GreaseBoss (YC W21) – Real-time system to manage industrial greasing https://bit.ly/3knXP8f

Launch HN: GreaseBoss (YC W21) – Real-time system to manage industrial greasing We are Steve, Tim and Pete, the cofounders of GreaseBoss ( https://bit.ly/2Nosc2t ). GreaseBoss is a hardware and software system that verifies that the greasing of industrial equipment is completed on time and according to specification. Greasing, you say? Yup, you heard that right. Incorrect greasing is the number one cause for machinery failure on industrial sites. Industrial machinery failure costs the global economy $21B a year. Greasing is a big deal! We know this is an unsexy part of the economy, so we won’t judge you if you have never heard of a zerk (grease point) before. Some of our favourite places you can find zerks include super yachts - 200 zerks, private planes - 80 zerks, breweries - 2000 zerks, theme parks - 1500 zerks. Other places with lots of zerks include factories, mines, utilities, farm equipment, trucks and military vehicles. The idea for GreaseBoss came when Steve and Tim saw frequent machine breakdowns due to incorrect greasing while supporting mine sites in Outback Australia. This problem costs Australian mine sites hundreds of millions of dollars in lost productivity every year - disrupted production, spending on parts and labour for repairs. We built and tested our prototypes during the pandemic lockdowns on the back deck, over Zoom calls. We have now developed our MVP and have quit our jobs to chase GreaseBoss full time. On the hardware side: we put RFID tags that fit like washers under each zerk. These are read by a head unit that is retrofittable to existing grease guns, which includes a custom RFID reader integrated into the nozzle. It also includes a flow meter and supporting electronics. Our device has 4G, Wifi and LoRa for comms, but also operates in an offline mode for customers in remote locations. Our hardware is rugged, dust proof, and water proof for some of the toughest operational environments (and operators..) On the software side, we record each greasing in the cloud, right as the worker greases the zerk. Since most industry is still tracking this using paperwork, you can imagine how much more efficient this is. Our customers get back to production much faster. We are building a HaaS (Hardware as a Service - is that a thing?) business model: we charge customers upfront for the hardware and then a software subscription fee. We are experimenting with per zerk, per machine and per site pricing. We haven’t found the sweet spot yet. We have GreaseBoss installed at a large coal mine, a quarry and on excavators at the dump in Queensland, Australia. We also have a South African greasing contractor using our system. We will be online for the rest of the day answering your questions (we are in AEST timezone). We are very excited to receive your ideas, experiences and feedback! February 23, 2021 at 07:11PM

Show HN: Recollec – Faster and Easier Remote Employee Onboardings https://bit.ly/3aMzHZV

Show HN: Recollec – Faster and Easier Remote Employee Onboardings Hey Everyone, My name is Firat, I’m the co-founder of Recollec [https://bit.ly/2NvLsec]. It’s a collaborative workspace for employee onboarding and upskilling. More and more companies announcing that they are going all remote. Given the conditions, we realized how hard it is to make employee onboarding training. It usually happens in the endless zoom calls, back and forth... Yet, most of these calls can be archived for another onboarding. Also, there are thousands of free content out there which you can redirect your employees to learn by themselves. So we build Recollec which is a collaborative workspace where every employee can share most useful content from various resources in one feed, and turn them into learning paths to create interactive onboarding experiences. To be honest, I was hoping to find some folks who have a problem with the employee onboarding process at their work. I really could use some help and feedback right now. I know your time is valuable, and I absolutely don’t want to waste it. So, maybe we could find a way to create a tailor made solution for your onboarding process at work, and save some time for you. Here’s our demo: https://bit.ly/3utmugb You can reach me out at firat@recollec.com Thanks everyone February 23, 2021 at 07:10PM

I’m Julien, the founder of Code Inspector, a platform that helps developers and managers produce better code and reduce technical debt. We would love to get some feedback from the Hacker News community. Our platform inspects code, looks for defects (security, vulnerability, design, performance, lack of documentation), automates code reviews and reports on team activity. You can customize violation alerts to reduce false positives. We currently support GitHub, Bitbucket and Gitlab. I’d love to hear your thoughts on what you would expect from such a platform (what you like, dislike) and what could help developers produce better code.

Launch HN: Abacum (YC W21) – Easy collaboration and reporting for finance teams https://bit.ly/2NPFCo2

Launch HN: Abacum (YC W21) – Easy collaboration and reporting for finance teams Hi HN! We're Jorge and Julio, cofounders of Abacum ( https://bit.ly/37IpFHk ). We're not sure how many fintech geeks like us are on HN but we're very excited to launch to you guys anyway! Abacum makes it easier for Finance teams to access real-time data, collaborate and generate reports. Think of having all the operational and financial data modeled in one place, and of the Finance team easily sharing and collecting information for other teams to make faster, better decisions. Scale ups have unique finance needs. First, they have spent the last years growing unnaturally fast, held together by a mixture of google sheets, csv files, a disconnected tech stack and a lot of copy paste. Second, growing 4x a year means that historical data is out of date within 3 months. Finally, with so many channels to stay connected, it's impossible to find where the Tech Lead shared that key assumption for the board forecast. Both Jorge and I have lived these experiences - we've spent too many long nights and days in number-crunching, without the proper time to analyze the data and to provide insights, becoming the key business partner we wanted. So yes, in the middle of the lockdown with 3 children each decided to leave everything to build the product we wish we had! Abacum can now connect to any data source, update a business plan automatically and give you finance specific tools to help you do what you need to. Think performance and pivot tables, cohort and waterfall graphs, and ways to easily collaborate. Our engine provides the flexibility of excel while minimizing human errors, reducing fears of breaking "the model" and scaling up to and past IPO size. We're big believers that collaboration, and not the business model, needs to be placed at the center of the product. Everything we built in Abacum is easily shareable and built to be easily understood by non-finance professionals. Ask (or remind) others in your company to collaborate, be it for updating forecasts or commenting on reporting decks, right where the needed context is. We've also set up different workflows for customers to easily gather the data bottom-up from different teams. We are constantly looking to improve Abacum, so we'd love to hear any feedback, questions or wisdom you have to share with us! We'd love to show you (or anybody that you think may be interested) a 10' demo of our product - please let us know and we'll reach out. Thanks so much, HN! February 23, 2021 at 02:20PM

Launch HN: Wyndly (YC W21) – Allergy relief through at-home oral drops https://bit.ly/3aIN5OI

Launch HN: Wyndly (YC W21) – Allergy relief through at-home oral drops Hi HN, I’m Aakash, and I’m a long time HN reader. My cousin Manan and I are excited to share our startup Wyndly ( https://bit.ly/3aEMltQ ) with HN today. Wyndly is focused on making long-term allergy relief convenient through at-home allergy immunotherapy drops and telemedicine. These personalized oral drops train your immune systems to stop reacting to allergy triggers like pollen, pets, or dust. Manan is an ear-nose-and-throat surgeon and allergy doctor, and in his physical practice, he’s treated thousands of patients with at-home allergy drops, a form of allergy immunotherapy. During allergy immunotherapy, you gradually introduce your immune system to your allergy triggers. Over time, your immune system learns to tolerate these allergy triggers and stops reacting to them. For patients, this means greatly reduced allergy symptoms and long-term relief [1] without any other medicine for years after patients finish their immunotherapy. While allergy drops are 80% of allergy immunotherapy in some European countries, in the United States, allergy drops are just 5.9% of allergy immunotherapy prescriptions [2] and are really only available in university hospitals like Johns Hopkins, University of Pittsburgh, and West Virginia University [3] [4] [5]. Part of the reason for their limited availability is physician training, and another part is the health insurance system’s incentives. Most allergy doctors were trained on allergy shots, and prescribe what they are most experienced with. Additionally, health insurance programs incentivize prescribing allergy shots. In his medical training, Manan trained on both allergy drops and shots. When Manan gave his patients the choice between at-home allergy drops and allergy shots, his patients always chose drops, which are safer, convenient, and don’t require needles [6]. When Covid-19 hit Denver in March 2020, Manan switched all of his allergy drop patients to online care to continue treatment. After shelter-in-place was lifted, his patients continued online care due to the convenience, which told us one thing—patients preferred and were comfortable with telemedicine for allergy care. And that's why we started Wyndly. We’re trying to make allergy immunotherapy convenient and affordable, so that any one of the 60 million people in America suffering from allergies has the opportunity to get lifelong relief—just like braces straighten your teeth and Lasik fixes your vision. We’ve done our best to make our patient experience as easy as possible. First, we learn more about you and your allergy history. Then, our medical team creates a personalized treatment plan with treatment sent straight to your door. Most patients notice benefits at 6 months, and some patients have reported allergy symptom relief as early as 6 weeks [7]. Patients lock-in lifelong allergy relief after a few years [1]. Throughout this time, we stay in touch with the patient to work with them towards allergy relief. Please let us know if you have more questions or feedback. We love talking about the science behind allergy immunotherapy, our treatment model, and what we’re doing. We're happy to answer any questions!

Launch HN: H3X (YC W21) – High power density electric aircraft motors https://bit.ly/3kaoDsB

Launch HN: H3X (YC W21) – High power density electric aircraft motors Hey HN! I’m Jason, one of the co-founders at H3X ( https://bit.ly/2ZHcGB4 ). We are building the lightest electric propulsion systems in the world. Our first product is a 250kW (330HP) integrated motor drive in a 18kg (40lb) package. It combines the electric motor, inverter, and gearbox into a single unit, resulting in an ultra-high-power density solution for electric aircraft (and other mass sensitive applications). In terms of electrification, we believe the aircraft industry is where automotive was ten years ago. There are many companies working on eVTOL and single-seaters, but very few are working on large commercial single-aisle electric aircraft such as a 737. This class of aircraft is absolutely critical to electrify as it accounts for the most passenger-miles [1] and is the biggest slice of the pie in terms of aviation emissions. Beyond the environmental impact, there are huge potential cost savings from both fuel (or lack thereof) and reduced maintenance for airlines. Aircraft are very mass sensitive so there are two main technology challenges that need to be solved to enable this class of electric aviation – (1) High energy density and efficient energy storage (batteries, hydrogen fuel cells, etc.) (2) Light, efficient, and high-power density electric propulsion systems (electric motors, power electronics, gearbox) There are many people working on (1) and great strides are being made [2][3]. We are focused on solving (2). A study done by the DOE determined that for a 737 to complete a five-hour flight, the propulsion system must be >12 kW/kg [4]. Today, best-in-class systems have a power density of 3-4 kW/kg. With our first product, we are targeting 13 kW/kg, making it an attractive solution for near-term Advanced Air Mobility (AAM) applications as well as an enabling technology for the aviation industry to enter the next stage of electrification. There are some cool things we are doing with the electromagnetics, power electronics, and the integration between the systems to get to the 13 kW/kg. There is not a single magic bullet, but rather a combination of multiple technological advances - 3D printed copper stator coils, high frequency SiC power electronics, and a synergistic cooling system to name a few. Our origins in electrification stem back to our college days where we built Formula-style electric racecars (s/o to Wisconsin Racing FSAE!). During year 1 of the program, we got so fed up with our COTS motors and inverters, we decided to go clean slate and build our own from the ground up the following year. Those were super happy fun times. Lots of dead IGBTs and all-nighters in the shop, but in the end, we got everything working and delivered! It was a true test of resilience and taught us how to GSD. Great preparation for starting a company. This led us to grad school and it became apparent during this time that the electric aircraft industry was a sleeping giant ready to be woken. We felt uniquely positioned to capitalize on this opportunity, so after about a year in industry, we left our full-time jobs and went all in. We’ve got a long road ahead - aviation is tough, there’s no denying that. In addition to the engineering challenges, there are also major certification barriers. However, CO2 is a serious problem and right now the major aviation players don’t have a compelling plan to meet the goals laid out in the Paris Agreement. Innovation needs to come from the outside and that’s what we’re doing at H3X. I’d love to hear your guys thoughts and would be happy to answer any questions you have.

Show HN: Peppa PEG – An Ultra Lightweight PEG Parser in ANSI C https://bit.ly/3bonny6

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://bit.ly/3aEUA9q 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]: https://bit.ly/2NNHmxL February 21, 2021 at 03:10AM

Launch HN: MindsDB (YC W20) – Machine Learning Inside Your Database https://bit.ly/2OPzo7X

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://bit.ly/3s8kUyr ). 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, especially if you need to write complex applications for ingesting data, training encoders and embedders, writing sampling algorithms, training models, optimizing, scheduling, versioning, moving models into production environments, maintaining them and then having to explain the predictions and the degree of confidence… we knew there had to be a better way! We aim to steer you away from constantly reinventing the wheel by abstracting most of the unnecessary complexities around building, training, and deploying machine learning models. MindsDB provides you with two techniques for this: build and train models as simply as you would write an SQL query, and seamlessly “publish” and manage machine learning models as virtual tables inside your databases (we support Clickhouse, MariaDB, MySQL, PostgreSQL, and MSSQL. MongoDB is coming soon.) We also support getting data from other sources, such as Snowflake, s3, SQLite, and any excel, JSON, or CSV file. When we talk to our growing community, we find that they are using MindsDB for anything ranging from reducing financial risk in the payments sector to predicting in-app usage statistics - one user is even trying to predict the price of Bitcoin using sentiment analysis (we wish them luck). No matter what the use-case, what we hear most often is that the two most painful parts of the whole process are model generation (R&D) and/or moving the model into production. For those who already have models (i.e. who have already done the R&D part), we are launching the ability to bring your own models from frameworks like Pytorch, Tensorflow, scikit-learn, Keras, XGBoost, CatBoost, LightGBM, etc. directly into your database. If you’d like to try this experimental feature, you can sign-up here: ( https://bit.ly/3pEX23M ) We currently have a handful of customers who pay us for support. However, we will soon be launching a cloud version of MindsDB for those who do not want to worry about DevOps, scalability, and managing GPU clusters. Nevertheless, MindsDB will always remain free and open-source, because democratizing machine learning is at the core of every decision we make. We’re making good progress thanks to our open-source community and are also grateful to have the backing of the founders of MySQL & MariaDB. We would love your feedback and invite you to try it out. We’d also love to hear about your experience, so please share your feedback, thoughts, comments, and ideas below. https://bit.ly/3aBrPKB or https://bit.ly/2ZtKq53 Thanks in advance, Adam & Jorge February 19, 2021 at 05:55PM

Launch HN: HiGeorge (YC W21) – Real-time data visualizations for public datasets https://bit.ly/3dv3xnA

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://bit.ly/3dx85to ). 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 datasets are hard to clean, poorly structured, and constantly updated. One publisher explained to us that she would refresh her state health department’s website 5 times a day waiting for updated COVID data, then manually download a CSV and clean it in Excel. This process could take hours, and it needed to happen every day. This is where HiGeorge comes in. We clean and aggregate public datasets and turn them into auto-updating data visualizations that anyone can instantly use with a simple copy/paste. Our data visualizations can be drag-and-dropped into articles, allowing news publishers to offer compelling data content to their communities. Check out a few versions of what we’re doing with customers -- COVID-19 data reporting at North Carolina Health News [1], COVID-19 vaccine site mapping at SFGATE [2], real-time crime reporting in Dallas, TX [3], and police use of force at Mission Local [4]. Today, HiGeorge works with dozens of newsrooms across the country. Our visualizations have driven a 2x increase in pageviews and a 75% increase in session duration for our partner publishers. We charge a monthly subscription for access to our data visualization library – a fraction of the cost of an in-house data engineer. In the long run, we are building HiGeorge so that it becomes the single place to collaborate on and publish data content. We’d love to hear from the HN community and we’ll be hanging out in the comments if you have any questions or feedback. [1] https://bit.ly/37x44Bz... [2] https://bit.ly/2ZzAU02...

Launch HN: Ontop (YC W21) – Easily hire and pay remote workers in LATAM https://bit.ly/3awhv6H

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 (https://bit.ly/3k4J8Xt) 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, collecting documents and sending money to different countries. We had to pay hundreds of gyms in LATAM and were frustrated by the amount of time we spent doing administrative work, when we should have been thinking on how to hack our way to growth. We handle all paperwork, compliance and payments so onboarding new people is really easy. And most importantly, everything done legally, by the book, so that companies are always due diligence proof. Our solution is tailored for LATAM guaranteeing the best speed and compliance in the market. We want to hear your thoughts on our solution. We value feedback and case uses that you might have. Email us at founders@ontop.ai and we will personally give you a demo. February 18, 2021 at 01:58PM

Launch HN: Datrics (YC W21) – No-Code Analytics and ML for FinTech https://bit.ly/3avf7wT

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://bit.ly/3pwzr56 ). 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 and business units to be implemented. It usually took months of work to turn an idea into a complete solution, going through data snapshot gathering to cleansing to experimenting to working with engineering and DevOps teams to turn experiments in Jupyter notebooks into a complete application that worked in production. Moreover, even if the application and logic behind the scenes were really simple (could be just dozens or hundreds of lines of code for a core part), the process to bring this to end-users could take ages. We started thinking about possible solutions when a request from one of the Tier 1 banks appeared, which confirmed that we’re not alone in this vision: their problem was giving their “citizen data scientists” and “citizen developers” power to do data-driven work. In other words, work with the data and generate insights useful for business. That was the first time I’d heard the term “citizen data scientist”. Our users are now these citizen data scientists and developers, whom we’re giving the possibility to manipulate data, build apps, pipelines, and ML models with just nominal IT support. Datrics is designed not only to do ML without coding, but to give analysts and domain experts a drag and drop interface to perform queries, generate reports, and do forecasting in a visual way with nominal IT support. One of our core use cases is doing better credit risk modeling - create application scorecards based on ML or apply rule-based transactional fraud detection. For this use-case, we’ve developed intelligent bricks that allow you to do variables binning and scorecards in a visual way. Other use cases include reports and pivot tables on aggregating sales data from different countries in different formats or doing inventory optimization by forecasting the demand without knowing any programming language. We’re providing 50+ bricks to construct ETL pipelines and build models. There are some limitations - a finite number of pre-built building blocks that can be included in your app, but if there is no block that you need, you can easily build your own ( https://youtu.be/BQNFcZWwUC8 ). Datrics is initially cloud-native, but also can be installed on-prem for those customers who have corresponding security policy or setups. The underlying technology, the pipeline execution engine is rather complex and currently built on top of Dask, which gives Python scalability for big datasets. In the next release, we are going to support Pandas as well as to switch intelligently between small datasets for rapid prototyping and big datasets for pipeline deployments. We’re charging only for private deployments, so our web version is free: https://bit.ly/3uaB3Fd . Try it to create your analytical applications with a machine learning component! We've put together a wiki ( https://bit.ly/37lP7SE ) to cover the major functionality, We are super-excited to hear your thoughts and feedback! We're big believers in the power of Machine Learning and self-service analytics and are happy to discuss what you think of no-code approaches for doing ML and analytics generally as well as the availability of them for non-data scientists. Or anything you want to share in this space! February 18, 2021 at 09:12AM

Launch HN: Worksphere (YC W21) – Manage flexible in-office or remote workspaces https://bit.ly/2N6YSNT

Launch HN: Worksphere (YC W21) – Manage flexible in-office or remote workspaces Hey HN, Aakhil, Theresa & Mark here at Worksphere ( https://bit.ly/37lUm4K ). 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 workplace regulations have cropped up, which are a pain and come with big financial risk if companies don’t comply (we’re looking at you CA businesses dealing with SB 1159 & AB 685 - learn more at https://bit.ly/2NhZ9xp... ). As the pandemic has continued (and continued, and continued) businesses are facing a new challenge. 75% of office employees report that they want a hybrid in-office and remote schedule. No one misses their 5-day-a-week commute. At the same time, collaboration and culture are hard to foster on Zoom and Slack alone. Employees still want access to an office when needed, but don’t want to come to work in an empty space. Businesses want the upsides of flexibility, but don’t want to pay for empty or only occasionally used desks — office space costs $10-12k per employee annually in major US cities. We believe that a hybrid workweek is a better workweek, and that an active approach is needed to make it a win-win for employees and businesses. Our features help businesses reopen safely and realize the full potential of a flexible workplace. We automate the wellness surveys, contact tracing, and capacity limits needed to enforce internal safety guidelines and regional regulations. This alleviates a ton of manual work for Office and HR managers. Employees can create in-office schedules and see who else is in the office to increase collaboration. We track office utilization data so companies can make smart decisions about their office space and lease. Worksphere is $6 per active employee/month, and our clients only pay for employees that come to the office. If you’re one of the 3 of 4 people who wants to work flexibly post-pandemic, or if you manage a workplace, we’d love to hear from you. How frequently do you think you’ll need office space? What problems are you facing in this changing work environment? We’ll reply in the comments or you can email us at info@worksphere.com. Thanks so much for your feedback! February 17, 2021 at 05:06PM

Launch HN: June (YC W21) – Two-click analytics reports on top of Segment data Hi HN! I’m Ferruccio, cofounder of June ( https://bit.ly/3k1dB8T ). 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://bit.ly/37liJzt and pick a template you’d like to try. Connect your Segment account, select the events required for your analysis, and get your insights. Looking forward to ideas and feedback from the community! February 16, 2021 at 05:15PM

Launch HN: Noya (YC W21) – Direct air capture of CO2 using cooling towers https://bit.ly/3rX2Mrm

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://bit.ly/3piYpF3 ). 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 century [1]; but, we haven't been able to widely apply this type of tech to scrubbing CO2 from the air because of its high cost. For example, one popular direct air capture project is estimated to capture 1M tons of CO2/year [2], but has an estimated equipment cost of $700M and all-in costs of ~$1.1B [3]. The single largest component of this cost is in the piece of equipment called the air contactor — the big wall of fans you see in the image linked above — which clocks in at $212M by itself. Yet fundamentally, all that air contactors do is put air into contact with something that captures CO2, whether it's an aqueous capture solution or some sort of solid sorbent. These costs felt astronomical to Daniel and I, so we set out with the singular focus to reduce the costs of carbon capture by reducing the costs of the air contactor. But no matter how we thought about it, we couldn’t get around the fact that to capture meaningful amounts of CO2, you need to move massive amounts of air since CO2 is very dilute in the atmosphere (0.04% by volume). Looking at the existing solutions, we began to understand why it makes sense to build something equally massive: so you can go after economies of scale. As Daniel and I were feeling stuck late one night, he got a call from his dad. They started talking about the refrigeration facility Daniel’s dad runs in Venezuela (where Daniel's from), and they started talking about the cooling towers at the facility. Cooling towers move air and water into contact with each other to provide cooling to industrial processes (descriptive video: https://www.youtube.com/watch?v=pXaK8_F8dn0 ). As Daniel listened to his dad, Daniel realized that if we could just add the blend of CO2-absorbing chemicals we had been developing into the water his dad’s cooling tower used, we could use it as an air contactor and achieve CO2 capture at the same time the cooling tower was cooling its processes. This eliminates the need to build millions of dollars worth of dedicated equipment to pluck CO2 from the sky. Our cooling-tower-based carbon capture process works as follows: we add our chemical carbon capture blend into a cooling tower's water, we connect the tower to some pieces of downstream processing equipment to regenerate the captured CO2, and then we pressurize the CO2 into cylinders for sale as "reclaimed CO2" to companies that need it. All of this is installed onto a cooling tower that another company already owns and operates. In exchange for letting us install this process on their towers, we will cover the cost of installation, and the companies will get a piece of the revenue generated through the sale of their CO2. We’re well on our way towards making this process a reality. We’ve partnered with a local farm to install our process in their cooling towers, and we've just produced CO2 using our industrial-scale prototype. We're excited for the opportunity to reverse climate change and ensure we have a future on this planet that is good. Please let us know what questions, concerns, or feedback you have about what we're building - I’ll be here all day! [1]: https://bit.ly/37fu83Q [2]: https://bit.ly/3dkaxmX...

Launch HN: Pyroscope (YC W21) – Continuous profiling software https://bit.ly/2OGZzOc

Launch HN: Pyroscope (YC W21) – Continuous profiling software Hi HN! Dmitry and Ryan here. We're building Pyroscope ( https://bit.ly/3poTrXB ) — an open source continuous profiling platform ( https://bit.ly/2ZkgmZu ). 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. We solved this issue by using sampling profilers — those work by looking at the stacktrace X number of times per second instead of hooking into method calls and that makes profiling much less taxing on the CPU. The next big issue that came up was storage — if you simply get a bunch of profiles, gzip them and then store them on disk they will consume a lot of space very quickly, so much that it will become impractical and too expensive to do so. We spent a lot of energy trying to come up with a way of storing the data that would be efficient and fast to query. In the end we came up with a system that uses segment trees [1] for fast reads (basically each read becomes log(n)), and tries [2] for storing the symbols (same trick that's used to encode symbols in Mach-O file format for example). This is at least 10 times more efficient than just gzipping profiles. After we did all of this we ran some back of the envelope calculations and the results were really good — with this approach you can profile thousands of apps with 100Hz frequency and 10 second granularity for 1 year and it will only cost you about 1% of your existing cloud costs (CPU + RAM + Disk). E.g if you currently run 100 c5.large machines we estimate that you'll need just one more c5.large to store all that profiling data. Currently we have support for Go, Python and Ruby and the setup is usually just a few lines of code. We plan to release eBPF, Node and Java integrations soon. We also have a live demo with 1 year of profiling data collected from an example Python app https://bit.ly/3rQKGa8... And that's where we are right now. Our long term plan is to keep the core of the project open source, and provide the community with paid services like hosting and support. The hosted version is in the works and we aim to do a public release in about a month or so. Give it a try: https://bit.ly/2ZkgmZu . We look forward to receiving your feedback on our work so far. Even better, we would love to hear about the ways people currently use profilers and how we can make the whole experience less frustrating and ultimately help everyone make their code faster and cut their cloud costs.

Show HN: Save 6 months to deploy your apps on AWS in 30 minutes I am Romaric, CEO of Qovery (https://bit.ly/3pjelr3) (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://bit.ly/3dcaWHX ). 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 apps and keep being as productive as possible. Instead of doing it for the next successful company, we decided to launch Qovery in Oct 2019. We have fundraised $1M (Techcrunch article), and we have been accelerated by Techstars. Since then, 1200 developers are using Qovery to deploy their apps, we have build a team of 8 engineers, and we are still hiring :) Join us in making the Cloud simple again :) I am eager to hear from you.

Show HN: Just, a command runner written in Rust Just lets you save and run commands from files with a terse, readable syntax similar to Make: build: cc *.c -o main # test everything test-all: build ./test --all # run a specific test test TEST: build ./test --test It is cross-platform, written in Rust, and actively maintained on GitHub: https://bit.ly/37fAksO Just has a bunch of nice features: - Can be invoked from any subdirectory - Arguments can be passed from the command line - Static error checking that catches syntax errors and typos - Excellent error messages with source context - The ability to list recipes from the command line - Recipes can be written in any language - Works on Linux, macOS, and Windows - And much more! Just doesn't replace Make, or any other build system, but it does replace reverse-searching your command history, telling colleagues the weird flags they need to pass to do the thing, and forgetting how to run old projects.

Show HN: A new(?) approach for your bookmarks https://bit.ly/3dn1u4X

Show HN: A new(?) approach for your bookmarks Hey HN community, there are a couple of websites I visit on a daily basis. I type the first two oder three characters of the url and the autocomplete feature of my browser does the rest. That is also how I procrastinate. It happens that i visit the same website over and over again without that there is really new content on that site. Or on the other side it happens that I forget to visit a certain site for some days. To address all this I build the following website: https://bit.ly/3u3xe51 The idea is: you have one personal link (1) and define a list of websites and how often you want to visit them. Then you set this link as your homepage or on your browser bookmark bar. Then by visiting your personal link you get redirected to a website of your list that you have not visited in your configured timespan. If there is no more website to visit you get redirect to a static site saying "all done, let's get back to work!". The second feature is that you can share the list of bookmarks (2) with others and they can create a copy of it and set their own timings and add/remove urls. I use this on my desktop pc and my mobile phone. Because it is the same link it is automatically synchronized on all your devices. It is a bit hard to explain. Hopefully you get the idea. But i tried it the last couple of weeks on my laptop and smartphone and love it! It really helps me stop procrastinating.

Launch HN: Cord (YC W21) – training data toolbox for computer vision https://bit.ly/2Z7vuJB

Launch HN: Cord (YC W21) – training data toolbox for computer vision Hey HN community - I’m Ulrik from Cord ( https://bit.ly/3qdaflw ) in the current YC W21 batch [1] - we are building software that allows people to label their data intelligently using a toolbox of various ‘labeling algorithms’. Labeling algorithms are any units of intelligence (e.g. a pre-trained model, or an interpolation algorithm) that help automate the annotation process. This enables data science and machine learning teams to rapidly iterate on their ML models without having to farm out labeling tasks to an external workforce. Today we’re launching the first part of our product, our Web App, which serves our initial set of automation features through a GUI. It also allows you to classify images and draw vector labels, visualize data, and perform collaborative QA. Computer vision ML algorithms are widely used for tasks like detecting everyday objects such as cars and pedestrians. However, they are yet to see widespread adoption for things like detecting cancerous polyps during an endoscopic procedure or blood clots in MRI scans. The lack of massive-scale labeled training datasets that fuel contemporary approaches is often the blocking element in building ML applications that solve these more specialised tasks. We also believe that the core part of the IP of an ML application stems from the labeled data used to train it. Creating these datasets is challenging for several reasons. Labeling the data requires expensive domain-expert annotators, and privacy might prevent the data from being sent to an external workforce. Ultimately most labeling work tends to be done using open-source tools that were not created for speed and purpose-built to handle massive-scale datasets[2]. These tools also tend to provide a poor experience for the end consumer of the training data (e.g., data scientists, ML engineers) because they lack intelligence and require high manual input. The initial seed of the idea came while I was working on a CS master’s project of visualizing massive-scale medical image datasets. I saw saw how much time and effort was being spent by doctors on labeling data. I met my co-founder Eric, who had worked as a quant researcher in finance, and after meeting him we realized we could take an algorithmic approach to tackling the labeling problem. Instead of writing trading algorithms, we turned our focus to writing labeling algorithms. For example, for a food calorie estimation project we translated image level classifications of food items to individualized bounding box labels using a labeling algorithm we wrote with our SDK, requiring only one manual label per food item. Although it was an image dataset, our algorithm approximated noisy bounding box labels by using a CSRT object tracker across images. It then trained a shallow Faster RCNN ‘micro-model’ on the noisy labels, ran inference on the data, and suppressed earlier noisy labels. We then quickly visually reviewed and adjusted the results on our Web App[3]. We have applied a similar approach in areas such as gastroenterology[4] and pathology. The days of relying on an army of human annotators and waiting to start the model building process are hopefully (soon) over. We are incredibly excited to be driving for that change - and are delighted to be sharing Cord with the HN community! We would love to hear your feedback. How are you going about creating and managing training data today? What are your key constraints? If you have used a creative method to label your data before, please share. Thank you so much in advance! [1] What I Learned From My First Month at Y Combinator - https://bit.ly/3a9Osp3...

Launch HN: Chorus Meditation (YC W21) – Meditation for Non-Meditators https://bit.ly/3jDau73

Launch HN: Chorus Meditation (YC W21) – Meditation for Non-Meditators Hey everyone! I’m Ali and, together with my co-founders MK and Warren, I’m building Chorus Meditation ( https://bit.ly/3jDauUB ). We provide online group meditation classes led by trained instructors. MK and I met after we both had found the benefits of a traditional meditation practice, but only after much difficulty getting started because it took over 30 days to feel the benefits and it can often feel isolating and like nothing is “working.” At the time, MK was a top SoulCycle instructor. She is a true master at creating community and motivating people to be their best through a perfect balance of humor, approachability, and deep vulnerability and acceptance. I was an avid SoulCycle rider and we bonded over our shared love for meditation and separately, our love for the instantly gratifying and social experience that SoulCycle had created. She and I decided that if we could create an experience for the mind that mirrored what SoulCycle had done for the body, we could help millions of people just like us. So, we spent months, combining different mindfulness techniques into a new method, testing out various versions on our living floors. We tried starting the class with a 3 minute traditional meditation before moving into the breathing pattern - no dice - we had promised people non-traditional meditation so when we hit them with exactly traditional meditation right at the start, it turned people off. Next we tried getting into the breathing pattern right off the bat -- still no dice. But we kept at it, and 16 major iterations later, we landed on what is now our Chorus class. Traditional meditation can be life-changing for those who stick with it, but the unfortunate truth is that for most people it’s hard to sustain the discipline to stick with it long enough to unlock the ah-ha moment. Once you cross that threshold you feel its power, but with Chorus we are trying to help people who struggle with that onboarding phase cross the threshold more easily. We've found that one of the main barriers many people run into with traditional meditation is that they're doing it alone, and they often feel like nothing is happening. So, we made Chorus 1) social, with warm, personable teachers and fellow class attendees, 2) fun, with new and popular music, and 3) designed to give motivating results in the first session and on-going. For example, the breathing pattern we use brings more oxygen into the body than normal inhales and exhales, which causes a tingling sensation, giving users a quick and satisfying feeling even in the first session. You can think of the tingles like endorphins in exercise - they feel good and tell you that something is working - so you are satisfied and want to come back for more. Everything in Chorus is designed to motivate you to keep going. Our members pay $40-a-month to have access to live and pre-recorded classes set to the beat of popular music like Beyonce, Odesza, Bon Iver, etc, that help them start their day with a positive mindset or unwind at night before bed. If you want to give it a try, we just launched a new class specifically designed to help you sleep — https://bit.ly/3p96yMh One of our users, a mother of young twins, shared: “my first experience unlocked something in me. Something visceral, and I thought - ‘this is so worth exploring.’” This is exactly the kind of reaction we’re going for. I want to emphasize that we’re in no way trying to replace traditional meditation. We, ourselves, are reverent students of traditional practices. And we're well aware that we don't have anything to teach the millennia-old traditions of India and China. What we are trying to do is bridge the gap for people who find traditional techniques challenging so that they can avoid the discouraging feeling of “I’m doing this wrong” and empower them to develop their own mindfulness practice. Another thing we do to support our users in the early stages of practice is provide a community in which they can share their experiences and get encouragement to keep going. This is one of the more satisfying aspects for us, because people report their positive experiences as well as their challenges. We hear from users who report feeling more calm and focused, or sleeping better, all the way up to "Chorus has truly transformed my life...I didn’t think I would ever have a relationship with my mom again, and now because of Chorus, I do.” We are building Chorus for our collective community, so I’d really love to hear this community’s feedback. We'd love to hear from everybody, whether you're a complete meditation skeptic, someone who's found meditation challenging, or a seasoned meditator who has achieved total equanimity! We're eager to hear your experiences and thoughts and feedback! Over to you, HN! February 11, 2021 at 05:25PM

Show HN: Hacker News Discourse turns HN stories into Clubhouse-style audio rooms https://bit.ly/2Z3NNiX

Show HN: Hacker News Discourse turns HN stories into Clubhouse-style audio rooms I'm Seth, creator of discourse.fm, a browser-based tool/platform to create live audio chat rooms. I just launched an extension of the site - https://bit.ly/2Niv00l - which pulls stories in real-time from the HN site using the public API, and enables anyone to join a live audio discussion about the story (think Clubhouse rooms autogenerated for HN stories). Once you enter a room, you can grab the link generated for a room and paste it back to the comments on the HN story to invite more participants. hackernews.discourse.fm is both a full-fledged product and a demo of how discourse.fm can be used to create live audio communities. HN is an ideal for this, as it benefits from its synchronicity, similarly-minded users, and it's basically a non-stop source of interesting discussion topics. That being said, almost any consistently active text-based community, forum, or news site could likely benefit from integrating live audio discussions. If you're interested in how you can use discourse.fm to accomplish this, let me know at info@discourse.fm. I'd love to hear feedback about what I've built. It would be especially cool (and very meta) to discuss this live using the room on the hackernews.discourse.fm site. Link: https://bit.ly/2Niv00l February 11, 2021 at 01:15AM

Launch HN: Wasp (YC W21) – DSL for building full-stack web apps https://bit.ly/3q8Daav

Launch HN: Wasp (YC W21) – DSL for building full-stack web apps Hi HN! We are Martin and Matija, twin brothers and creators of Wasp ( https://bit.ly/3bEYKMU ). Wasp is a declarative language that makes it really easy to build full-stack web apps while still using the latest technologies such as React, Node.js and Prisma. Martin and I both studied computer science where we mostly focused on algorithms for bioinformatics. Afterwards we led engineering teams in several SaaS companies, on the way gaining plenty of experience in building web apps. Moving from one project to another, we used various technologies: JQuery -> Backbone -> Angular -> React, own scripts / makefile -> Grunt -> Gulp -> Webpack, PHP -> Java -> Node.js, … , and we always felt that things are harder than they should be. We were spending a lot of time adopting the latest tech stack and figuring out the best practices: how to make the web app performant, scalable, economical and secure and also how to connect all the pieces of the stack together. While the tech stack kept advancing rapidly, the core requirements of the apps we were building changed very little (auth, routing, data model CRUD, ACL, …). That is why about 1.5 years ago we started thinking about separating web app specification (what it should do) from its implementation (how it should do it). This led us to the idea of extracting common web app features and concepts into a special specification language from which we could generate code in the currently popular technologies. We don’t think it is feasible to replace everything with a single language so that is why we went with a DSL which integrates with the modern stack (right now React, NodeJS, Prisma). Wasp lets you define high-level aspects of your web app (auth, routing, ACL, data models, CRUD) via a simple specification language and then write your specific logic in React and Node.js. The majority of the code is still being written in React and Node.js, with Wasp serving as the backbone of your whole application. To see some examples of what the language looks like in practice, take a look here: https://bit.ly/2MQmTIA... The main difference between Wasp and frameworks (e.g. Meteor, Blitz, Redwood) is that Wasp is a language, not a library. One benefit of that is a simpler and cleaner, declarative syntax, focused on the requirements and detached from the implementation details. Another benefit of a DSL is that it allows Wasp to understand the web app’s requirements during the build time and reason about it before generating the final code. For example, when generating code to be deployed to production, it could pick the most appropriate architecture based on its understanding of the web app and deploy it to serverless or another type of architecture (or even a combination). Another example would be reusing your data model logic through all the parts of the stack while defining it just once in Wasp. DSL opens the potential for optimisations, static analysis and extensibility. Wasp’s compiler is built in Haskell and it compiles the source code in Wasp + React/Node.js into the target code in just React and Node.js (currently in Javascript, but we plan to move to Typescript soon). The generated code is human readable and can easily be inspected and even ejected if Wasp becomes too limiting. We are currently in Alpha and many features are still rough or missing, but you can try it out and build and deploy web apps! There are things we haven’t solved yet and others that will probably change as we progress. You can check out our repo at https://bit.ly/3aUx86K and give it a try at https://bit.ly/3jGlr7F . Thank you for reading! We would love to get your feedback and also hear about your experiences building web apps - what has worked for you and where do you see the opportunities for improvement?

Show HN: How you got your first 10 users for your product? We are all building some kind of product or business and gaining the initial set of users can be a difficult task. They are not only the users, but they play a very big role as they believed in your product, they should provide the non-biased review about your product and that will define how you'll shape your product. So, I would be grateful if you can share the process of getting your initial set of users. By this, we'll learn from each other's experience, we'll appreciate each other's effort and help out the maker who need help with their initial set of users.

Launch HN: SigNoz (YC W21) – Open-source alternative to DataDog https://bit.ly/3jz5Dnp

Launch HN: SigNoz (YC W21) – Open-source alternative to DataDog Hi HN, Pranay and Ankit here. We’re founders of SigNoz ( https://bit.ly/2Z07S9H ), an open source observability platform. We are building an open-core alternative to DataDog for companies that are security and privacy conscious, and are concerned about huge bills they need to pay to SaaS observability vendors. Observability means being able to monitor your application components - from mobile and web front-ends to infrastructure, and being able to ask questions about their states. Things like latency, error rates, RPS, etc. Better observability helps developers find the cause of issues in their deployed software and solve them quickly. Ankit was leading an engineering team, where we became aware of the importance of observability in a microservices system where each service depended on the health of multiple other services. And we saw that this problem was getting more and more important, esp. in today’s world of distributed systems. The journey of SigNoz started with our own pain point. I was working in a startup in India. We didn’t use application monitoring (APM) tools like DataDog/NewRelic as it was very costly, though we badly needed it. We had many customers complaining about broken APIs or a payment not processing - and we had to get into war room mode to solve it. Having a good observability system would have allowed us to solve these issues much more quickly. Not having any solution which met our needs, we set out to do something about this. In our initial exploration, we tried setting up RED (Rate, Error and Duration) and infra metrics using Prometheus. But we soon realized that metrics can only give you an aggregate overview of systems. You need to debug why these metrics went haywire. This led us to explore Jaeger, an open source distributed tracing system. Key issues with Jaeger were that there was no concept of metrics in Jaegers, and datastores supported by Jaeger lacked aggregation capabilities. For example, if you had tags of “customer_type: premium” for your premium customers, you couldn’t find p99 latency experienced by them through Jaeger. We found that though there are many backend products - an open source product with UI custom-built for observability, which integrates metrics & traces, was missing. Also, some folks we talked to expressed concern about sending data outside of boundaries - and we felt that with increasing privacy regulations, this would become more critical. We thought there was scope for an open source solution that addresses these points. We think that currently there is a huge gap between the state of SaaS APM products and OSS products. There is a scope for open core products which is open source but also supports enterprise scale and comes with support and advanced features. Some of our key features - (1) Seamless UI to track metrics and traces (2) Ability to get metrics for business-relevant queries, e.g. latency faced by premium customers (3) Aggregates on filtered traces, etc. We plan to focus next on building native alert managers, support for custom metrics and then logs ( waiting for open telemetry logs to mature more in this). More details about our roadmap here ( https://bit.ly/3cSyce9 ) We are based on Golang & React. The design of SigNoz is inspired by streaming data architecture. Data is ingested to Kafka and relevant info & meta-data is extracted by stream processing. Any number of processors can be built as per business needs. Processed data is ingested to real-time analytics datastore, Apache Druid, which powers aggregates on slicing and dicing of high dimensional data. In the initial benchmarks we did for self-hosting SigNoz, we found that it would be 10x more cost-effective than SaaS vendors ( https://bit.ly/3a5XjIG ) We’ve launched this repo under MIT license so any developer can use the tool. The goal is to not charge individual developers & small teams. We eventually plan on making a licensed version where we charge for features that large companies care about like advanced security, single sign-on, advanced integrations and support. You can check out our repo at https://bit.ly/3p0lyvP We have a ton of features in mind and would love you to try it and let us know your feedback! February 9, 2021 at 05:29PM

Launch HN: Great Question (YC W21) – Customer research tools for software teams https://bit.ly/3tCBhoF

Launch HN: Great Question (YC W21) – Customer research tools for software teams Hi HN! I’m Ned and along with my co-founder PJ (pjmurraynz) we’re building Great Question ( https://bit.ly/3cXKhie ) to make it easy to do customer research as part of every sprint or product release. The maxim of Y Combinator is “talk to customers, build something people want” yet relatively few software teams regularly engage in customer research. This was definitely the case for us in our last startup, and even when we sold that business to a place with a well resourced research team we were largely on our own. Without any real tools or processes to do customer research we ended up muddling through, but it was always ad hoc - and often skipped so we could just get a release out the door. Bad news. By talking to lots of customers (meta!) we learned that one of the biggest challenges teams face is in the logistics of research: finding customers to talk to, scheduling calls & paying incentives. The research community calls this Research Operations. We’re setting out to fix these problems by building tools that make it easy for small teams to do what companies like Facebook and Google do with massive teams of research coordinators. We help you do better customer research, more often in four ways: First, we help you build an on-demand pool of research subjects. These are customers who opt in to be notified about customer interview requests and surveys, or find out about beta product releases. They could also be customers you find in other forums or communities, through content marketing or direct outreach. Second, we let you book time with a customer in a couple of clicks, or send out a survey or prototype test. We give you templates to save you creating these things from scratch every time, but also to keep you following best practice. Templates like Product Market Fit surveys are live now with more advanced ones like Van Westendorp pricing surveys coming soon (email me for early access). Third, we handle all the messaging on platform to protect the privacy and consent of your users but also to manage what's called "participant fatigue", and handle any incentives to make sure you get the responses you need. Finally, we make it easy to share what you’re learning with your team. Store your notes, observations, video files and transcripts in one place. Post it to Slack, get an email digest of learnings & upcoming interviews, and find previous research reports in one central place. All of this is to say we’re building the tool we wish we had while building product at our last startup, and also in the belly of the beast after we got acquired. The tool that helps you go from having some big gnarly question to start getting answers in minutes, and which brings your team along for the journey. We use the tool religiously in-house and it's had a massive impact on not only our own product development process, but our first engineering hire (ex Twitch) has noted how much more connected he feels with our customers and the product he's building. What do you all think? We’d love your feedback on the product and our approach. In particular we’d love to know how customer research works at your company and the challenges you face making it happen! February 9, 2021 at 05:09PM
