Show HN: Cadseer. a parametric solid modeling CAD desktop application https://ift.tt/yXnP0cq
Show HN: Cadseer. a parametric solid modeling CAD desktop application Cadseer is in the same genre as: solidworks, inventor, freecad etc... Cadseer is alpha software, so lots of missing features, bugs, crashes, file incompatibilities etc... About me: I spent 15 years designing stamping dies on a high end cad system. During that time, I also developed and marketed extensions/plugins toward that cad system. Through that experience, I came disillusioned with 'vendor lock-in' and proprietary software in general. I basically retired, took the vow of poverty and moved all my computing to open source. I have since, and continue to, try and improve the open source cad environment. https://ift.tt/JV9DBFQ March 31, 2023 at 02:35PM

Show HN: Multi-Display Screen Sharing with CoScreen by Datadog https://ift.tt/Ri3LHOw
Show HN: Multi-Display Screen Sharing with CoScreen by Datadog Good to be back on HN with all-new CoScreen, a little more than 3 years after it launched over here! With CoScreen 5.0, you can now share your windows from multiple displays at the same time, a long standing request by our most avid users and impossible in other apps. It also has a lightning-fast, Rust-based window compositing, scaling, and streaming engine now. CoScreen was always meant to be different so that you and your team can share your screens simultaneously and multi-directionally, and to be able to control what is being shared. We saw it as a natural extension and closely coupled with your OS — instant, fast, and seamless. A better way to pair program, debug tough incidents, or jam on great ideas by sharing multi-modal information like code, commands, graphs, or logs. All that made a lot of sense conceptually but to be frank, it was hard to get it right. Now a part of Datadog and with major parts of our app rewritten in Rust, we feel we’re closer than ever. Here’s what pair programmers liked about CoScreen, so we made it even better: - High definition code sharing: Windows are video-streamed in real-time at their native resolution whenever possible. You never have to search for your IDE anymore or be anxious to share the wrong window. - Multi-directional collaboration: You can share, while Alice shares, while Bob shares. Side-by-side, across multiple displays. With built-in crisp audio and video chat. - 60FPS+ super smooth mouse pointers. Type, click, and draw on any shared window as if it was your own. What some of you did NOT like, so we fixed it in CoScreen V5: - CPU utilization and latency have been reduced drastically as various parts of our desktop client are now implemented in Rust, building on crates such as cxx, rust-skia, iced, as well as Neon for our native remote control plugins. - No more accidental clicking into remote windows through the new remote window toggles. - You’re no longer bound by your displays, can share windows from multiple of them at the same time and even move them across displays while sharing without stopping. - You’ll also soon be able to join meetings from your browser from any platform. CoScreen runs on macOS (x64 and Apple Silicon), Windows, soon also on the web and is currently free. We’re planning to charge for larger teams and enterprise features in the future. Hopefully - finally - we’ll also have a Linux version one day. Tell us if you need it urgently and if you have any other requirements! https://ift.tt/qPzXNbl March 31, 2023 at 09:51AM

Show HN: Yesterday I open sourced StratusGFX, a realtime 3D rendering engine https://ift.tt/iO1K6uU
Show HN: Yesterday I open sourced StratusGFX, a realtime 3D rendering engine It's been closed source for a long time while I worked on it on and off as a hobby research project, but yesterday the repo was made public for the first time under the MPL 2.0 license. A feature reel showing its capabilities can be found here: https://ift.tt/bkfxq6d... A technical breakdown of a single frame can be found here: https://ift.tt/NT2fiqj... It's still in a very beta state (bugs and instability expected), but I felt like it was a good time to make it public since a lot of its core features are mostly presentable. I plan to continue working on it in my spare time to try and improve the usability of the code. Two main use cases I could see for it: 1) People using it for educational purposes. 2) People integrating it into other more general purpose engines that they're working on since Stratus is primarily a rendering engine. Any extensions to the rendering code that are made public would then further help others. So I think it will remain very niche but I'm hoping it will still be helpful for people in the future. https://ift.tt/CtBvAlw March 30, 2023 at 05:55AM

Show HN: Sendsecurely.io – an audited secure file sharing platform https://ift.tt/EiH1OlI
Show HN: Sendsecurely.io – an audited secure file sharing platform Hi HN! tldr: SendSecurely is a secure platform to send sensitive documents and files to others. All files are encrypted locally before uploading to SendSecurely. The decryption keys are also encrypted and managed by a new audited database system. Anytime anyone accesses the decrypted keys, an audit log is created letting you keep track of everyone you have shared the file with and when they have accessed it. We would love for you to try this new system and share feedback! long (and technical) story: My partner and I have been working for the past 2 years on building a new privacy-oriented database system called EthicalDB. EthicalDB utilizes blockchain technology to codify both database schema and database permissions. All data in EthicalDB must be associated with an entity in the database and predefined by the schema as public or private data. Permissions are also defined in the schema. Private data is stored encrypted within EthicalDB in a special way that requires multiple nodes to provide decryption keys to access the private data. This forms the basis of governance and accountability in the system such that no one node can access the private data. For private data to be accessed, a private data request must be submitted to the blockchain ledger from an entity existing within EthicalDB. The nodes validate that the entity has permission to access the requested private data and then submit decryption keys for the entity to be able to access the data. In this way, there is no separation between data access and audit - you must submit a data request to get access to the data. We view this radically different architecture and design from traditional database systems as necessary if we wish to codify privacy policies and truly have support for individual personal data ownership and protection. After a combined 25 years working as internet application developers, my partner Travis and I saw that database systems sucked at storing personal data and any attempt to do so was an afterthought. Core problem: every database system is designed assuming the hosting organization has full ownership of all the data within the system. We asked ourselves what would a database system look like if a system was designed from the ground up to respect privacy and personal data ownership? - EthicalDB is what resulted. There are many uses we can see for EthicalDB, but one of the first applications we felt comfortable building and releasing to the public is a secure file sharing platform. We would love input and feedback on SendSecurely! We'd be also happy to discuss with anyone interested a technical deep dive on the EthicalDB technology. Thanks for checking this out! https://ift.tt/iwQ32AY March 30, 2023 at 12:20AM

Show HN: Marvin – build AI functions that use an LLM as a runtime https://ift.tt/RhlyuKx
Show HN: Marvin – build AI functions that use an LLM as a runtime Hey HN! We're excited to share our new open-source project, Marvin. Marvin is a high-level library for building AI-powered software. We developed it to address the challenges of integrating LLMs into more traditional applications. One of the biggest issues is the fact that LLMs only deal with strings (and conversational strings at that), so using them to process structured data is especially difficult. Marvin introduces a new concept called AI Functions. These look and feel just like regular Python functions: you provide typed inputs, outputs, and docstrings. However, instead of relying on traditional source code, AI functions use LLMs like GPT-4 as a sort of “runtime” to generate outputs on-demand, based on the provided inputs and other details. The results are then parsed and converted back into native data types. This “functional prompt engineering” means you can seamlessly integrate AI functions with your existing codebase. You can chain them together with other functions to form sophisticated, AI-enabled pipelines. They’re particularly useful for tasks that are simple to describe yet challenging to code, such as entity extraction, semantic scraping, complex filtering, template-based data generation, and categorization. For example, you could extract terms from a contract as JSON, scrape websites for quotes that support an idea, or build a list of questions from a customer support request. All of these would yield structured data that you could immediately start to process. We initially created Marvin to tackle broad internal use cases in customer service and knowledge synthesis. AI Functions are just a piece of that, but have proven to be even more effective than we anticipated, and have quickly become one of our favorite features! We’re eager for you to try them out for yourself. We’d love to hear your thoughts, feedback, and any creative ways you could use Marvin in your own projects. Let’s discuss in the comments! https://ift.tt/0yAZiF8 March 29, 2023 at 10:04PM

Show HN: PoachMe.dev, Reclaim Your Time https://ift.tt/sw58yXV
Show HN: PoachMe.dev, Reclaim Your Time A couple of months ago, I posted about my stealth startup on HN and got a lot of friendly help and signups so I'm officially launching today to a wider audience. All of the features highlighted here are "FREE" (we just take a cut from your scheduled recruiter calls) PoachMe.dev is your one stop shop to being paid for the time you spend with recruiters on finding a job. From the hiring manager, to the recruiter, to the HR team cutting you an offer letter, every single person in the chain is getting paid while a candidate gets to pretend their money and time and resources aren't dwindled every time they take an interview so this turns it back on it's head. Have you ever received a random message asking for a random technology you don't have while also claiming "you're a perfect fit"? Send them a pre-composed "reply template message" from PoachMe ("Great. Please book a slot on my calendar and we can chat more about this. You'll receive my resume upon confirmation of the booking. https://ift.tt/yaOvATx ") so they can schedule and pay for your time. You will be surprised how many great recruiters will blatantly tell you that you are not worth your time as soon as they're asked to pony up even $100/hr while making an easy 10k for placing you at a company. If your skills have value, you can cut through the recruiter chaff and get to the recruiters who are actually easy to work with in one easy step. After we built this core feature, we've branched out to creating a career snapshot (https://ift.tt/mYi9jZh) which allows you to showcase your skills in one single screen without it being a resume and have started work on a virtual business card you can update and flash unto NFC cards so you have a digital business card you can carry around with you ( https://ift.tt/40H3wVY ) Sign up today using the following limited signup code ( https://ift.tt/CXHkF6o ). Although I am sure I am able to scale this startup to any size, limiting signups is a super easy way to not get HN-hugged-to-death. https://ift.tt/fkK2QVp March 28, 2023 at 04:15AM

I've never built an iOS app before, and even if I made something like this as a web app (my usual job), I would expect it to take at least a week. My process was basically 1) Ask ChatGPT to write some code 2) Copy and paste the code into the right files (this took a little bit of React knowledge on my part). 3) Run the code and paste any errors back to ChatGPT and ask it for suggested solutions. 4) Repeat. https://ift.tt/v8M9ZQ3 March 26, 2023 at 04:43AM

Show HN: FTX Creditor – Confirm that the bankruptcy court has your claim https://ift.tt/z0V4Dwl
Show HN: FTX Creditor – Confirm that the bankruptcy court has your claim FTX Creditor is the easiest way to confirm that the bankruptcy court knows about your claim. Background: Last week, FTX published 1.3M anonymized user accounts in a Schedule F filing that lists the unsecured creditors they know about. 1.3M is a huge number, but it may be less than half of the total users FTX had. If your account is not listed, file a proof of claim with the bankruptcy court, or they may not treat you as a creditor (Federal Rules of Bankruptcy Procedure: Rule 3003). The data was uploaded as a series of PDFs, which makes it hard to find your claim, especially if you don’t remember the exact amounts you had and have to fuzzy match with cmd+f! We built FTX Creditor so that you can find your claim with the information you have. Features: - Find claims by: - Assets. If you remember having 4-5 BTC, 10-20 ETH, 0-100 SOL, you can filter 1.3M claims down to 4. - USD value. The face value of a claim is the account value on November 11, the day FTX filed for bankruptcy. You can exclude “Sam Coins” from the value calculation. The court may ignore the value of assets closely associated with SBF, such as FTT and SRM. - Customer code. - See the court document a claim was listed in. - Subscribe for notifications about events that may impact your claim, such as when the court sets the deadline to file a proof of claim. - Search for terms across all public court filings. Future Work: - Creditors who are interested in selling their claims can receive offers from buyers. - Explore aggregate statistics across accounts and assets. - FAQ on the most relevant parts of the bankruptcy process. FTX creditors, we got this! https://ift.tt/uyDFQlV March 24, 2023 at 04:42PM

Alinor enables, scientists, engineers, and researchers to focus on what they do best: solving the world's biggest problems, by working on the cutting edge of materials and physical science. While we focus on selling their martials and enabling them to reach wider adaption. Alinor covers everything from initial inquiry to final invoice and everything in between. We do believe that nearly all problems the world is facing can be solved by advanced materials. Happy to answer any questions you might have, including what are advanced materials, just don't ask me to explain it in Arabic.

Show HN: Tripnotes.ai: Intelligent Travel Planner Hey HN, We're excited to announce the public beta preview of Tripnotes, an intelligent travel planner that mixes a custom recommendation engine, our own data, and a bit of GPT to help you find the right places to go while traveling. Our team has been working hard on this project for 6 months, and we're excited to finally share it with the HN community. With Tripnotes, you can keep track of all your notes about travel when planning to visit a city. Paste in article URLs, videos, emails, text messages, any other text, and if you need some help with research, ask our Concierge which will provide useful recommendations and itineraries for the city in question - with a fallback to GPT for things we didn't quite understand. If you're not ready to dive right in, here are a few short highlight videos: https://twitter.com/matthewer/status/1619047755271536640 https://twitter.com/matthewer/status/1621172173598756864 https://twitter.com/matthewer/status/1623703548545445890 https://twitter.com/matthewer/status/1638010661694234625 All the places by Tripnotes are from our own database, but we rely upon GPT to understand the intent of the incoming prompts, as well as to help with the prose in our response to ensure the place descriptions fit what's being asked for. Since we tweeted about our preview release on Monday, we've had over 15,000 people come and try at least one prompt, with over 40,000 unique notes generated from prompts about cities all over the world. We'd love for you to give Tripnotes a try and let us know what you think. The "unauthed" version is open to everyone. If you're interested in using the full version, please join our waitlist. The full version maintains a history of your notes and allows you to edit the text and auto-highlights any text you write/paste in on the fly, which can be useful for pasting recommendations from friends (say via SMS or Email) and having them auto-highlighted and mapped. You can also paste in links from articles, websites, blogs, even Tiktok or Youtube. We scrape those urls, gather the list of places that are mentioned, and then show them on the map along side the rest of your note. We'd love to hear your thoughts and feedback, so please feel free to leave a comment or reach out to us directly. Thanks for your support! https://tripnotes.ai/ March 23, 2023 at 11:35AM

Also had to buy a virtual number online to allow setting up a WhatsApp account with. The WhatsApp servers receive the message from the WhatsApp mobile application, which forward a webhook request to the application server I setup. The request gets forwarded to the ChatGPT API (i.e the OpenAI Chat API), and voila, you are now in conversation with ChatGPT Interestingly, the ChatGPT API does not provide context recognition from previous conversations out of the box. That is something that needs to be built in manually. So currently, the ChatsApp service does not include the context recognition from previous conversations. Maybe something to look at building out in the future. https://ift.tt/cZADymq March 22, 2023 at 03:13AM

We're open-sourcing it now and are excited to share it with you: https://ift.tt/BG1ZNHS Why we built this: - There are many solid frameworks for FE / browser testing, but none with high-level constructs for testing BE flows - We were missing a way to validate side effects for complex backend systems, especially across async queueing systems Our beta version lets you send an API call to a system and then: - Validate (=assert) calls to any downstream microservice in REST and GRPC - Validate queries/writes to DBs Assertions are validated through the use of OpenTelemetry, as we see it as an easy-to-use way to observe how backend systems behave.

San Francisco’s Transit-First Policy Turns 50
San Francisco’s Transit-First Policy Turns 50
By Michael Delia
Published March 17, 2023 at 02:12PM
https://ift.tt/hdRrCVW
By Michael Delia
Transit on Market Street in downtown San Francisco, 2018
It’s been a half-century since the San Francisco Board of Supervisors put transit needs above all other traffic initiatives, and now, the city’s Transit-First policy is celebrating its golden anniversary. The policy guides the city’s work on major infrastructure projects and planning efforts. Its principles drive San Francisco officials to promote incentives that reduce traffic congestion and solo vehicle trips, support transit investments including the purchase of Muni buses and light rail vehicles, and regularly evaluate how well our transportation network functions.
Adopted on March 19, 1973, the original Transit-First policy was born out of an effort to reshape the Municipal Railway so it could serve San Franciscans' needs more effectively. The goals were very specific:
- Create exclusive bus lanes and prohibit automobiles from streetcar and cable car tracks.
- Restrict turning movements of automobiles that conflicted with transit vehicles.
- Extend sidewalks at transit stops to allow boarding from the travel lane.
- Strictly enforce parking codes and tow-away regulations along major transit corridors.
- Consider the use of preemptive traffic signals for transit vehicles.
By the early 70s, San Francisco streets had become increasingly crowded. The Freeway Revolt just over a decade earlier led to the cancellation of planned highway construction in the city, and an office boom downtown was bringing in thousands of commuters. Meanwhile, the San Francisco Bay Area Urban Renewal Association (SPUR) began a comprehensive review of Muni’s operations in 1972. The organization interviewed operators and management, conducted line checks and reviewed company properties and processes to identify areas for improvement.
“The recurring theme was most Muni vehicles were operating in traffic. This was the source of many problems — schedule bunching, accidents, unhappy operators and riders,” said Jim Chappell, executive director of SPUR from 1994-2009.
The recommendations in SPUR’s report, “Building a New Muni,” were well-received by the mayor and city supervisors, and the Transit-First policy was passed not long after its release. Transit-First also addressed concerns about increased air pollution and environmental damage by effectively putting the personal automobile on notice.

New equipment, transit priority and a focus on complete funding for Muni were initial hallmarks of the policy. The passage of Proposition E, a city charter amendment, in 1999 further enhanced Transit-First by including protections in the landmark legislation for people walking and bicycling.
“San Francisco’s Board of Supervisors showed remarkable foresight in adopting the Transit-First resolution, and it no doubt helped San Francisco remain one of the strongest public transit cities in the nation,” said Jason Henderson, San Francisco State University Geography and Environment professor and author of Street Fight: The Politics of Mobility in San Francisco.
In addition to making transit, walking and biking more attractive, Transit-First also promotes equity. When residents have options beyond cars, employment and economic opportunity can grow, as does the opportunity to reduce greenhouse gases.
Professor Henderson believes San Francisco was the first city in the country to adopt a policy to prioritize public transit, but that doesn’t mean the work is done. “Transit-First must no longer be advisory,” he said. “[New policies are] needed so that public transit, cycling and walking are more than aspirational.”
In recent years, the “Muni Forward” program has reflected the Transit-First policy with 80 miles of transit priority street improvements. Among those improvements, diamond-marked transit lanes have evolved to become the present-day “Red Carpet” lanes reserved exclusively for buses and taxis to reduce travel times and the impact of traffic congestion on Muni schedules. Meanwhile, Market Street has gone through various redesigns in the downtown area over the years. Following boarding island and lane improvements, San Francisco’s busiest thoroughfare received its first red transit lanes in 2014 and was declared “Car Free” in a monumental celebration on January 29, 2020.

Today we can see the Transit-First policy in action in the now open Central Subway and projects such as the Van Ness Bus Rapid Transit (BRT) corridor and the Muni Forward L Taraval Improvement Project that is now under construction to add transit lanes, make the route more accessible and improve pedestrian safety and visibility. With Transit-First entering its 51st year, there are new challenges as the COVID-19 pandemic has driven many people back into private cars. However, the SFMTA’s improvement projects continue with a focus on proven strategies that make transit, walking and bicycling the city’s preferred modes of travel.

Show HN: Notch – an off-the-shelf software ecosystem for chips Hi HN! I'm a firmware developer who, like many others, has always been upset at the state of the firmware ecosystem. Semiconductor companies tend to be very bad at providing useful code and tools for their chips. That's why I started Notch - to handle this stuff for them. Our first product is an off-the-shelf driver generation tool (similar to STM32CubeMX, MCUExpresso, etc.) that can be adapted to any IC, not just microcontrollers. Better yet, it's cross-platform, cross-language (Rust too, if you want), and code can be generated from the terminal, meaning it doesn't lock you in to some shitty Eclipse IDE. https://ift.tt/LKe4M57 March 16, 2023 at 12:36PM
Show HN: Quality News – Towards a fairer ranking algorithm for Hacker News https://ift.tt/LZPEsqU
Show HN: Quality News – Towards a fairer ranking algorithm for Hacker News Hello HN! TLDR; - Quality News is a Hacker News client that provides additional data and insights on submissions, notably, the upvoteRate metric. - We propose that this metric could be used to improve the Hacker News ranking score. - In-depth explanation: https://ift.tt/56svc4P The Hacker News ranking score is directly proportional to upvotes, which is a problem because it creates a feedback loop: higher rank leads to more upvotes leads to higher rank, and so on... → ↗ ↘ Higher Rank More Upvotes ↖ ↙ ← As a consequence, success on HN depends almost entirely on getting enough upvotes in the first hour or so to make the front page and get caught in this feedback loop. And getting these early upvotes is largely a matter of timing, luck, and moderator decisions. And so the best stories don't always make the front page, and the stories on the front page are not always the best. Our proposed solution is to use upvoteRate instead of upvotes in the ranking formula. upvoteRate is an estimate of how much more or less likely users are to upvote a story compared to the average story, taking account how much attention the story as received, based on a history of the ranks and times at which it has been shown. You can read about how we calculate this metric in more detail here: https://ift.tt/56svc4P About 1.5 years ago, we published an article with this basic idea of counteracting the rank-upvotes feedback loop by using attention as negative feedback. We received very valuable input from the HN community ( https://ift.tt/TdipFjM ). Quality News has been created based largely on this feedback. Currently, Quality News shows the upvoteRate metric for live Hacker News data, as well as charts of the rank and upvote history of each story. We have not yet implemented an alternative ranking algorithm, because we don't have access to data on flags and moderator actions, which are a major component of the HN ranking score. We'd love to see the Hacker News team experiment with the new formula, perhaps on an alternative front page. This will allow the community to evaluate whether the new ranking formula is an improvement over the current one. We look forward discussing our approach with you!

Show HN: Chainloop, A Software Supply Chain Attestation solution devs won't hate Hi, my name is Miguel and I am very happy to share what's been months worth of work :) The project has rough edges for sure, but any early feedback, comments or concerns are appreciated! === The Problem === You work on the Security and Operations (SecOps) team in charge of your organization's Software Supply Chain Security. You feel pretty good about the state of things already, your developer teams are signing their commits, deliverables, scanning for vulnerabilities,… Life is good! Then you realize that you are not compliant with the latest security requirements. You get referred to slsa.dev and are told that you need to be at least level 3, whatever that means! Aha! I “just” need to implement an attestation and artifact layer in our Software Supply Chain, which you complete after a couple of months of work. Now to the easy part (or what you think). To make the developer teams adopt it. You quickly realize that standardizing best practices and security requirements is very hard. Development and SecOps team dynamics are clashy and poorly defined due to priorities mismatch. Also, from the developer's point of view, it’s very time-consuming and frustrating to pollute your CI/CD systems with convoluted, error-prone and complex processes to comply with the SecOps team. So there has to be a better way that satisfies both sides... === The Solution === Enter Chainloop. You can think of it as an API for your organization's Software Supply Chain that both parties can use to interact effectively to meet their mismatched priorities. SecOps teams regain security compliance, visibility, standardization and control by having a mechanism to define and propagate attestation requirements. Developers, on the other hand, get jargon-free tooling that can be used to meet compliance with minimum friction and effort. === Give it a try === Eager for feedback from the community so please reach out. Happy to chat! Thanks! PS: You can see an attestation end-to-end demo here https://www.youtube.com/watch?v=Q_0dlBqKtIU&t=384s https://ift.tt/9ztNLOv March 16, 2023 at 07:34AM

Show HN: Ingest data from your customers (Prequel YC W21) https://ift.tt/RgkXK7t
Show HN: Ingest data from your customers (Prequel YC W21) Hey HN! Charles here from Prequel (https://prequel.co). We just launched the ability for companies to import data from their customer’s data warehouse or database, and we wanted to share a little bit more about it with the community. If you just want to see how it works, here’s a demo of the product that Conor recorded: https://ift.tt/N4TVfte. Quick background on us: we help companies integrate with their customer’s data warehouse or database. We’ve been busy helping companies export data to their customers – we’re currently syncing over 40bn rows per month on behalf of companies. But folks kept on asking us if we could help them import data from their customers too. They wanted the ability to offer a 1st-party reverse ETL to their customers, similar to the 1st-party ETL capability we already helped them offer. So we built that product, and here we are. Why would people want to import data? There are actually plenty of use-cases here. Imagine a usage-based billing company that needs to get a daily pull from its customers of all the billing events that happened, so that they can generate relevant invoices. Or a fraud detection company who needs to get the latest transaction data from its customers so it can appropriately mark fraudulent ones. There’s no great way to import customer data currently. Typically, people solve this one of two ways today. One is they import data via CSV. This works well enough, but it requires ongoing work on the part of the customer: they need to put a CSV together, and upload it to the right place on a daily/weekly/monthly basis. This is painful and time-consuming, especially for data that needs to be continuously imported. Another one is companies make the customer write custom code to feed data to their API. This requires the customer to do a bunch of solutions engineering work just to get started using the product – which is a suboptimal onboarding experience. So instead, we let the customer connect their database or data warehouse and we pull data directly from there, on an ongoing basis. They select which tables to import (and potentially map some columns to required fields), and that’s it. The setup only takes 5 minutes, and requires no ongoing work. We feel like that’s the kind of experience every company should provide when onboarding a new customer. Importing all this data continuously is non-trivial, but thankfully we can actually reuse 95% of the infrastructure we built for data exports. It turns out our core transfer logic remains pretty much exactly the same, and all we had to do was ship new CRUD endpoints in our API layer to let users configure their source/destination. As a brief reminder about our stack, we run a GoLang backend and Typescript/React frontend on k8s. In terms of technical design, the most challenging decisions we have to make are around making database’s type-systems play nicely with each other (kind of an evergreen problem really). For imports, we allow the data recipient to specify whether they want to receive this data as JSON blob, or as a nicely typed table. If they choose the latter, they specify exactly which columns they’re expecting, as well as what type guarantees those should uphold. We’re also working on the ability to feed that data directly into an API endpoint, and adding post-ingestion validation logic. We’ve mentioned this before but it bears worth repeating. We know that security and privacy are paramount here. We're SOC 2 Type II certified, and we go through annual white-box pentests to make sure that all our code is up to snuff. We never store any of the data anywhere on our servers. Finally, we offer on-prem deployments, so data never even has to touch our servers if our customers don't want it to. We’re really stoked to be sharing this with the community. We’ll be hanging out here for most of the day, but you can also reach us at hn (at) prequel.co if you have any questions!

Show HN: Mr. Graph. A graph deifnition and execution library for Python https://ift.tt/KGy9wqF
Show HN: Mr. Graph. A graph deifnition and execution library for Python What: Mr. Graph is a python library designed to make composing graphs of sync and async functions easy! Use google style docstrings to automagically create dataclasses and chain together function calls into graphs. Why: I like the design of Dagster, but not the latency. For apps and systems engineering, sometimes I want to compose a graph out of regular python functions. I don;t need all the heavy machinery that comes with a full workflow engine. Current features: - Use with either async or sync functions - Uses google style doc strings to name return values. - Creates dataclasses for each function's output. - Can infer pipelines from input and output signatures - All directed acyclic graph layouts supported. linear, fan-in, fan-out. Future Features: - Better examples for use with async calls (like LLMs) - Splitting dataclasses, better error handling, logging improvements. This is under active development. Any feedback, interest, or contributions are appreciated. Thanks! https://ift.tt/JRmZUij March 15, 2023 at 12:30PM

Show HN: Using GPT-3 and Whisper to save doctors’ time https://ift.tt/Emy8Odk
Show HN: Using GPT-3 and Whisper to save doctors’ time Hey HN, We're Alex, Martin and Laurent. We previously founded Wit.ai (W14), which we sold to Facebook in 2015. Since 2019, we've been working on Nabla ( https://nabla.com ), an intelligent assistant for health practitioners. When GPT-3 was released in 2020, we investigated it's usage in a medical context[0], to mixed results. Since then we’ve kept exploring opportunities at the intersection of healthcare and AI, and noticed that doctors spend am awful lot of time on medical documentation (writing clinical notes, updating their EHR, etc.). Today, we're releasing Nabla Copilot, a Chrome extension generating clinical notes from video consultations, to address this problem. You can try it out, without installation nor sign up, on our demo page: https://ift.tt/K9ptCqD Here’s how it works under the hood: - When a doctor starts a video consultation, our Chrome extension auto-starts itself and listens to the active tab as well as the doctor’s microphone. - We then transcribe the consultation using a fine-tuned version of Whisper. We've trained Whisper with tens of thousands of hours of medical consultation and medical terms recordings, and we have now reached an error rate which is 3× lower than Google's Speech-To-Text. - Once we have the transcript, we feed it to a heavily trained GPT-3, which generates a clinical note. - We finally return the clinical note to the doctor through our Chrome extension, the doctor can copy it to their EHR, and send a version to the patient. This allows doctors to be fully focused on their consultation, and saves them a lot time. Next, we want to make this work for in-person consultation. We also want to extract structured data (in the FHIR standard) from the clinical note, and feed it to the doctor’s EHR so that it is automatically added to the patient's record. Happy to further discuss technical details in comments! --- [0]: https://ift.tt/ArC2b0k March 14, 2023 at 10:16AM

Show HN: PixelForge.art – Leveraging Whisper to verticalize 16/9 YouTube videos Hi there! I've been a YouTube content creator during few years (50k subs, ~5M views) and I realized that many creators on the platform have their content stolen and republished on TikTok, Instagram Reels or YouTube Shorts for monetization purposes. I built PixelForge to tackle this problem. The tool allows content creators to work on their horizontal video as they usually do. But once the video is published, they can quickly generate tiktoks/shorts/reels without having to go through the tedious process of video editing again. https://pixelforge.art March 14, 2023 at 11:19AM

Show HN: Versionfeeds – Custom RSS feeds for releases of your favorite software Hi HN! I am quite excited as this is my second product, launched today: Versionfeeds. https://ift.tt/EKlIjOz What is Versionfeeds? I was quite annoyed by the fact that I had no central place where I could see all the software releases. I use software a lot, be it at my job, to build my side projects, or tools hosted on my NAS at home. It's literally dozens, if not hundreds of tools, packages or even programming languages. And most of them receive updates regularly. That is why I built Versionfeeds. It allows me to bundle all the releases for the software I need and love, into one dedicated feed. At the moment, all public repositories on Github and Gitlab are available. You can also search on npm (Javascript) and Packagist (PHP) for your software. More providers will come soon. The feeds adhere to the Atom standard and can be consumed with any feed reader. If maintainers use markdown in their release notes, it will be converted to HTML. Any feedback, wishes and ideas are welcome. Please share your thoughts with me. <3 March 8, 2023 at 10:02AM

Show HN: Co-locating Debian Bullseye with an evil maid https://ift.tt/5IwQOHk
Show HN: Co-locating Debian Bullseye with an evil maid In order to facilitate the secure co-location of a server, I looked into protecting a Debian Bullseye system from evil maid attacks. In addition, since I've enjoyed using ZFS for some time, I decided to rely on a natively encrypted ZFS root file system. Basically... I'd like to take a system containing sensitive information, box it up, and drop it in the mail without worrying about losing it or having it wind up in the wrong hands. A couple of things became clear while researching how to do this. First, there should be little chance that a rogue data-center admin can insert malicious software. When the system reaches the data center and gets powered on we should be confident that it's running our software completely unmodified. As I understand things, Secure Boot is designed to help with this and therefore should be enabled. However, by relying on Secure Boot alone, there will be no remote method of knowing that it hasn't been disabled until after the ZFS pass-phrase is provided to the initramfs via dropbear. At that point it's too late. An evil maid could have already subverted dropbear, for example, and just now stolen the pass-phrase. To avoid this I realized that a second requirement of using a TPM device to automatically unlock the ZFS root was in order. TPM devices have the ability of "sealing" data to so-called Platform Configuration Registers (PCR). This feature allows the data to be accessed only if the "measured" system state matches some original expected state. The TPM can fully start the system unattended but, if anything's unexpectedly meddled with, act like a tripwire requiring the pass-phrase to be typed in manually. If we ssh in and reach dropbear requesting the pass-phrase, we'll know that we either need to update our sealed data after a grub/kernel/initramfs update... or someone's been messing with our start up code. This window of opportunity will be too small for an evil maid to take practical advantage of. This sounded like the right track and I set out to try and configure both, Secure Boot and TPM unlocking of an encrypted ZFS root. I thought it'd take a few hours at most but it actually turned out to be a fair challenge. After a few failed attempts I started tenaciously documenting every avenue. Ultimately I developed helper scripts that can reproduce the configuration should the time come to actually ship a machine out the door. I'm reasonably satisfied with the outcome. However, the scripts haven't been reviewed and neither has the overall process itself. There were a lot of guides I followed that contained typos, bugs, dubious information or simply different requirements. I'm not sure everything is exactly "bullet-proof" for this show HN. For example, I'm beginning to wonder if Secure Boot is necessary and if the TPM alone is sufficient. So naturally, comments and criticisms regarding everything are greatly appreciated. The script files can be found here: https://ift.tt/voDQCa0 and here: https://ift.tt/YQbgDxf Finally, I hope this effort will be useful to others facing similar needs. March 8, 2023 at 04:19AM

Show HN: GraphAr – Open-source file format for archiving/exchanging graph data https://ift.tt/jA7SHY0
Show HN: GraphAr – Open-source file format for archiving/exchanging graph data Hi, Hacker News! We're excited to announce the release of GraphAr, an open-source file format for archiving and exchanging graph data. The landscape of graph processing systems is fragmented, with diverse types of systems, including graph databases, graph computation systems, and GNN systems. However, there is currently no common file format for efficiently storing and exchanging graph data that maintains its schema and graph semantics. GraphAr is designed to address this issue by providing a simple, lightweight format for storing and exchanging graph data. GraphAr is a flexible and adaptable format that can be used across a variety of applications, by decoupling the storage of metadata, adjacency, and properties. It's also designed to be efficient, by leveraging existing formats such as ORC, Parquet, and CSV as much as possible. This makes it easy to integrate with existing data processing systems and provides a level of familiarity for users. GraphAr also keeps the semantics of graphs, and can preserve the schema of property graphs. This means that users can maintain the same graph structure across different systems, ensuring that the semantics of the graph are not lost. We've developed both a C++ library for accessing and creating GraphAr files, and a Spark library for transforming data into and from GraphAr files. With these libraries, it's easy to work with GraphAr files in your existing Spark connectors or C++ projects. As GraphAr matures, we aim to move the project to a vendor-neutral venue, such as Apache, LF AI & Data. This will ensure that the project continues to be developed in an open and transparent manner, with contributions from a broad community of developers. To get started with GraphAr, check out our GitHub repository, where you'll find detailed documentation and examples of how to use the libraries. We welcome any feedback or contributions to the project. Let's make graph data archiving and exchange more efficient with GraphAr! https://ift.tt/GgdDAiv March 6, 2023 at 04:31AM

It replaces torch.load() with a custom function that produces a dictionary that materializes tensors on the fly. Compared to other solutions it doesn't require sharding or re-encoding checkpoints and uses them completely as-is. It is a foundation to make it possible to run inference and compress language models and other large models one layer at a time - in principle, even one tensor at a time. I describe the rationale and technical details of the library's design in the blogpost: https://ift.tt/2I53z0S https://ift.tt/OmIoECT March 3, 2023 at 02:29PM

Show HN: Build a knowledge base from your Slack content https://ift.tt/6jXIx9F
Show HN: Build a knowledge base from your Slack content Hello HNers! We are Maria and Stuart from DataQA ( https://dataqa.ai/ ). We want to make sure companies never "lose" important information on Slack. We have built a Slack app to easily bookmark and tag important content, such as announcements, FAQs or actionable decisions, and save it inside an internal knowledge base. All inside of Slack. Anyone who uses Slack regularly will be aware of its shortcomings when it comes to the amount of noise that can be generated. Even with the best of intentions, companies can easily end up with too many noisy channels, where relevant discussions happen at the same time as more informal chats. This is not only a distraction for people, but is also a problem when trying to go back and search past history for important information. The data in Slack is proprietary knowledge of companies and should not get locked inside the Slack platform. Both Stuart and I have felt this pain at our previous jobs. How do we solve this problem? With DataQA, you can save important messages or threads in the form of question-answer pairs, and tag them with relevant tags, e.g. #front-end-updates. All the saved content is then displayed in the Slack app home page, no need to login to another service. The app also comes with search, as well as a bot to quickly access all the saved knowledge. We only see what we need to see: the app only has access to the channels it's invited to, and all data gets deleted if the app gets uninstalled from the workspace. We are offering the app for free at the moment, and would love to hear feedback from the HN community! https://dataqa.ai/ March 3, 2023 at 04:06AM

Show HN: Nordic Game Jam 2023 https://ift.tt/6taySp3
Show HN: Nordic Game Jam 2023 Hi HN :-) We are hosting our Nordic Game Jam 2023, 13-16 April, at Aalborg University, Copenhagen. Nordic Game Jam has been running since 2006, it is an annual, 48 hours, game jam with a focus on bringing the games industry together, both veteran and hobbyist, in a playful, experimental and educational form. We just had our first talk announcement: "Porting your Unity knowledge to Godot Engine", which fits perfectly if you are interested in the new developments of Godot Engine. We will be announcing many more activities throughout this month. I have been part of the organiser team for 3 years now. It is completely volunteer driven. It was though to get through COVID as we highly appreciate the in-person culture. Incredibly grateful to be back again! I am merely sharing because we tend to get a bit limited to the nordic countries (no wonder!), but we had quite a few participants from other countries who loved coming and getting a sneak peek into how the Nordic games industry looks. https://ift.tt/hjWYxtw March 2, 2023 at 09:11AM

Show HN: SQL-puzzle, a highly composable and functional query builder sql-puzzle is a highly composable and functional query builder. It is a lightweight wrapper for Sequelize and is written in TypeScript. sql-puzzle is built around the idea of composing functionalities and code reuse. This is achieved by defining SQL constructs at the lowest possible level and building upon those. https://ift.tt/kgpwtjR March 2, 2023 at 08:17AM
Show HN: Quality News – Towards a fairer ranking algorithm for Hacker News https://ift.tt/cSCNuWO
Show HN: Quality News – Towards a fairer ranking algorithm for Hacker News Hello HN! TLDR; - Quality News is a Hacker News client that provides additional data and insights on submissions, notably, the upvoteRate metric. - We propose that this metric could be used to improve the Hacker News ranking score. - In-depth explanation: https://ift.tt/g5m0vwJ The Hacker News ranking score is directly proportional to upvotes, which is a problem because it creates a feedback loop: higher rank leads to more upvotes leads to higher rank, and so on... → ↗ ↘ Higher Rank More Upvotes ↖ ↙ ← As a consequence, success on HN depends almost entirely on getting enough upvotes in the first hour or so to make the front page and get caught in this feedback loop. And getting these early upvotes is largely a matter of timing, luck, and moderator decisions. And so the best stories don't always make the front page, and the stories on the front page are not always the best. Our proposed solution is to use upvoteRate instead of upvotes in the ranking formula. upvoteRate is an estimate of how much more or less likely users are to upvote a story compared to the average story, taking account how much attention the story as received, based on a history of the ranks and times at which it has been shown. You can read about how we calculate this metric in more detail here: https://ift.tt/g5m0vwJ About 1.5 years ago, we published an article with this basic idea of counteracting the rank-upvotes feedback loop by using attention as negative feedback. We received very valuable input from the HN community ( https://ift.tt/2CT7hMw ). Quality News has been created based largely on this feedback. Currently, Quality News shows the upvoteRate metric for live Hacker News data, as well as charts of the rank and upvote history of each story. We have not yet implemented an alternative ranking algorithm, because we don't have access to data on flags and moderator actions, which are a major component of the HN ranking score. We'd love to see the Hacker News team experiment with the new formula, perhaps on an alternative front page. This will allow the community to evaluate whether the new ranking formula is an improvement over the current one. We look forward discussing our approach with you!

Show HN: Supaglue – open-source unified API https://ift.tt/8p5Pzha
Show HN: Supaglue – open-source unified API Last month, we open-sourced Supaglue (https://ift.tt/87qwXAx) as a developer toolkit for building customer-facing Salesforce integrations. Since then, we've been iterating on our approach with users and are re-launching Supaglue as an open source unified API, starting with CRMs. With our re-launched public alpha you can: - Interact with HubSpot and Salesforce through a unified REST API - Sync data from HubSpot and Salesforce into a local Postgres cache and make reads against a normalized CRM schema - Make writes (POST and PATCH) to HubSpot and Salesforce using the unified API - Open source MIT license so anyone can self-host for free Today we support reads, creates, and updates for Accounts, Contacts, Leads, and Opportunities for HubSpot and Salesforce. In the coming weeks, we plan to add more connectors and features like configuring sync frequencies, webhooks for notifications, sync rate limiting/throttling. We'd love to hear your thoughts and any feature requests! Give it a try and let us know what you think! GitHub: https://ift.tt/87qwXAx Website: https://supaglue.com March 1, 2023 at 12:07PM
Show HN: MiniMock, a minimalist, header-only, C/C++ mock library https://ift.tt/GqM4kbX
Show HN: MiniMock, a minimalist, header-only, C/C++ mock library Hello HN! Here is MiniMock : a minimalist, header-only, C/C++ mock library. It's a side project of my current side project. MiniMock is a tentative to create a mock library that is : - quick and easy to integrate, - quick and easy to learn, - quick and easy to use. In short, MiniMock offers basic mock features by providing only 9 macros : - 3 macros to structure tests : BEGIN_TESTS, TEST, END_TESTS. - 4 macros to compare things : EXPECT, EXPECT_MSG, ASSERT_MSG, NEAR. - 2 macros to mock functions : MINI_MOCK_FUNCTION, MINI_MOCK_ON_CALL. And it relies on native C++ language to do everything else. The repo contains a readme and a minimal example to have an idea. Currently it's a quick-and-dirty-proof-of-concept but I'm interested to know if this approach seems appealing to you. Also let me know if something similar exists, I would be happy to use it instead of reinventing the wheel. A little more context on why I started MiniMock : - All mock frameworks that I know are full-featured, heavy and complex, they require a lot of time and energy to learn and use. - However my needs for mocks are really basic, mocking a function or comparing two variables are conceptually very simple things. - So I naively believe that doing a simple thing could be simple. - So I started MiniMock even if (or because) I'm not a mocking-guru. English is not my native language, please let me know if something isn't clear in the readme or in the discussion. Thanks https://ift.tt/kuNFVGP March 1, 2023 at 11:33AM

Show HN: Rapid Kubernetes Controller Development with Tilt and Silly Drawings Like the says. I'm describing how to use Tilt to speed up the dev cycle of testing and coding Kubernetes controllers. Tilt uses a built in local registry to push images into and can use hot swapping to kickly deploy processes in containers. It's pretty neat. :) The Tiltfile can be a bit daunting but I'm trying to break it down as much as possible. :) I hope this helps! Good luck! https://ift.tt/zH6plZS March 1, 2023 at 07:08AM
