Show HN: Engineering group to help medical staff against Covid-19 We've created an engineering group to help in the event of a severe COVID-19 crisis. Right now we have engineers, PhDs, and the owner of a manufacturing company, with a supply chain and offices in New York, Florida, and Taiwan. The idea behind the group is that a COVID-19 outbreak might be something our medical system hasn't seen before. There may be shortages or special needs of medical equipment and other resources. We think we can help by building certain devices. We probably can't build ICUs, but we could provide real help to a burdened medical front-line in a crisis. We're doing this in a deliberate and pragmatic way, informed by medical opinion. Right now, we're looking for more help—anyone with project management, engineering as well as non-technical experience. We're especially looking for doctors, particularly those with emergency room, triage experience, or who have (are) dealing with th...

Show HN: Quickly Test and Integrate ML Models with Booklet.ai Hey HN, Adam here, one of the founders of Booklet (https://booklet.ai). As a previous machine learning team leader, we would have a team celebration every time an API endpoint was created to serve a new model, but a model behind an API endpoint was rarely useful for other teams. Marketing wanted LTV predictions in their sales tool, the email team wanted customer segments in their email tool, and operations wanted sales forecasts in their warehouse management system. Those integration steps were painful and slow for the data team to build, especially with proper production-ready stability. We built Booklet.ai to make these post-deployment integration steps easier. We connect to existing ML endpoints (on Sagemaker or any other tool) and you can set up a quick testing UI for spot-checking. From there, set up sources (ex: AWS Redshift) to feed into the model for predictions and destinations (ex: Intercom) for those predictions t...

Launch HN: Datree (YC W20) – Best practices and security policies on each commit We are Shimon and Eyar, co-founders of Datree ( https://www.datree.io ). We've built software to help engineering teams automate the adoption of development best practices, coding standards, and security policies. When I (Shimon) was the manager of a 400-developer company's infrastructure engineering team, we had an issue where a developer committed AWS secret keys into a public GitHub repo. We were very, very lucky that the bad actors who quickly got ahold of the keys "only" spun up compute instances to mine bitcoin. Mistakes happen and they happen to the best of us. No developer wants to make mistakes, especially ones impacting production - because those mistakes can be not only costly to the business, but also an emotional pain for the developer. After finding out about the issue, I had to search for any other leaked secret in our repositories to make sure we were no longer exposed. Th...
