Show HN: Browser Extension to make a language test out of any website https://ift.tt/2ZQ0v5e

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://ift.tt/3swC3SN Firefox: https://ift.tt/2ZMgXDh If you didn't enjoy my explanation skills, there is an example video here: https://ift.tt/2OYXUUk 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 12:41AM

Show HN: Summarize IPs (bulk geo, asn, privacy report for IP addresses) https://ift.tt/3pQaOk8

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://ift.tt/3dGPH1p You can paste any arbitrary text into the tool at https://ift.tt/3snYnxQ 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 08:16AM

Launch HN: GreaseBoss (YC W21) – Lubricate with Confidence https://ift.tt/2NolF7X

Launch HN: GreaseBoss (YC W21) – Lubricate with Confidence We are Steve, Tim and Pete, the cofounders of GreaseBoss ( https://ift.tt/37CHvva ). 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 10:11AM

Show HN: Recollec – Faster and Easier Remote Employee Onboardings https://ift.tt/2ZK3M5S

Show HN: Recollec – Faster and Easier Remote Employee Onboardings Hey Everyone, My name is Firat, I’m the co-founder of Recollec [https://recollec.com]. 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://ift.tt/3qMcNqY You can reach me out at firat@recollec.com Thanks everyone February 23, 2021 at 10:10AM

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 Hi HN! We’re Jorge and Julio, cofounders of Abacum ( https://www.abacum.io/ ). 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 05:20AM

Launch HN: H3X (YC W21) – High power density electric aircraft motors https://ift.tt/3qERuaO

Launch HN: H3X (YC W21) – High power density electric aircraft motors Hey HN! I’m Jason, one of the co-founders at H3X ( https://www.h3x.tech ). 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 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!

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, 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://ift.tt/3uhw05U ) 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://ift.tt/3k6zsfm or https://mindsdb.com/ Thanks in advance, Adam & Jorge February 19, 2021 at 08:55AM
