Show HN: Website for creating self-signed certificates https://ift.tt/cNHbewg

Show HN: Website for creating self-signed certificates If you're developing locally and need to use HTTPS for whatever, then this tool is hopefully useful to you. I made it because there's a lot of bad info online about generating self-signed certificates. For instance, a lot of guides don't use the SAN list extension or show you how to create a proper certificate chain. Firefox doesn't allow a CA certificate to be used as an end certificate. Getting a working certificate can get pretty confusing, especially for newcomers to certificates or webdev. Having a website for this also means the process of getting a certificate is the same, no matter if you're on a Unix-like OS or Windows. A WebAssembly module built with C++ and Mbed TLS is used to create the keys and certificates. TypeScript and Preact is used for the UI. https://ift.tt/pLetjPq March 18, 2024 at 12:54AM

Show HN: Interactive Smartlog VSCode Extension – An Interactive Git GUI https://ift.tt/7dJaq5w

Show HN: Interactive Smartlog VSCode Extension – An Interactive Git GUI Interactive Smartlog is a graphical VSCode extension that presents a simplified view of the Git log, directly highlighting the branches and commits that are most relevant to your current work. And it's not just a visual tool — it's fully interactive, allowing you to add/switch/remove branches, stage/unstage files, and manage commits directly from the GUI. This tool draws inspiration from Meta's Interactive Smartlog built for the Sapling source control system, and I've adapted it to work with Git. Transitioning the functionality from Sapling to Git wasn't just about a one-to-one feature transfer; it involved changing how data is queried & presented, as well as introducing UI interactions for several Git concepts (like branches, staging/unstaging changes, etc) which are not present in the Sapling source control system. Originally a personal project to enhance my own workflow, I've published the extension on the VSCode marketplace for anyone who would like to use it. I'm keen to hear your feedback and suggestions, as community input is invaluable in shaping its future updates. https://ift.tt/niRlZ0Y March 17, 2024 at 06:28AM

Show HN: SatCat5, the open-source FPGA Ethernet switch https://ift.tt/M7CGwFL

Show HN: SatCat5, the open-source FPGA Ethernet switch We've just launched v2.5 of SatCat5, the open-source FPGA Ethernet switch [1]. SatCat5 contains various FPGA building blocks that let you build a custom mixed-media Ethernet switch. It was originally intended for cubesats [2] but has many other potential applications. The headline feature for this release is support for the IEEE-1588 Precision Time Protocol (PTP). SatCat5 has demonstrated end-to-end synchronization to within 50 ps-rms, which is approaching the world-leading performance of CERN's White Rabbit Project [3]. Except we're doing time-transfer over regular, non-synchronous Ethernet. The key breakthrough is a new technology for digital timestamps that we've published in IEEE Access [4]. This project was featured on HN back in 2023 [5]. Since then, we've changed to the CERN-OHL-W v2.0 license, which has much better legal clarity for FPGA projects.

Show HN: DBOS – Transactional Serverless for TypeScript Apps https://ift.tt/qzR3Z0h

Show HN: DBOS – Transactional Serverless for TypeScript Apps Hello HN! We’re excited to show you DBOS, a transactional serverless SDK and platform that makes it easy to write fault-tolerant, observable, and scalable TypeScript applications. We’re a startup commercializing research we did at Stanford and MIT. ( https://ift.tt/atNuZsx ). The main idea behind DBOS is to store EVERYTHING about your application in the database. This gives you some unique features: * Reliable execution – Your program’s execution state is stored in the database, so if it’s ever interrupted, it automatically resumes from where it left off without repeating any work already performed. * Time travel – Every change to your program’s state is recorded in the database, so you can “rewind” time and restore the state of your application to what it was at any point in the past. For example, time travel debugging–take a tricky bug in production, rewind time, and reproduce it locally on your laptop. Today, we released our open-source SDK ( https://ift.tt/o6KOdiB ) and our free-to-try serverless platform ( https://ift.tt/AsbjQt2 ). We’d love for you to try them out and let us know what you think! Here’s a quick guide to get you started: https://ift.tt/Ot2JF6r We’re here to answer any questions! https://ift.tt/o6KOdiB March 13, 2024 at 02:29AM

Show HN: StableBuild – make any Docker container deterministic https://ift.tt/rQq4TLs

Show HN: StableBuild – make any Docker container deterministic Hi HN! I've posted this a few weeks back without much HN traction - today we've added a free community tier, so anyone can try it out. TL;DR: We’ve launched StableBuild, a new tool to easily freeze and pin Docker images, operating system packages, Python packages, and arbitrary build dependencies; in 5 lines of code: https://stablebuild.com . As the CTO at an ML startup w/ 75 people ( https://ift.tt/4BztGec ) I’ve grown incredibly frustrated with non-deterministic builds. Last year basically every week one of our containers (we have 40+ unique ones in prod) would stop working properly because some dependency was updated or removed. This ranges from Nvidia deleting cuda base images from Docker Hub, to Chromium being removed from the Ubuntu package registry in favor of the snap version, to pandas 2 being published with breaking APIs - while everyone just depends on e.g. pandas>=1.4. This has been super disruptive because builds break for no apparent reason: someone pushes some unrelated code change, a container needs to be rebuilt, now it gets the latest dependencies => boom, either a compile error or an integration test fails. Many times this even blocks deployment. If the build system has decided that a container on master needs to be rebuilt, we can’t deploy the complete system if a dependency has shifted. And, fixing this naturally falls on the most senior engineers. Anyway, to fix this I’ve funded (together w/ my Edge Impulse cofounder) StableBuild. It’s a set of mirrors and registries that let you easily freeze and pin Docker images, apt/apk packages, Python packages, and arbitrary files and URLs from the internet. It currently consists of: * A custom pull-through cache for Docker Hub, that makes any image pulled immutable. Protects against updated or removed images; and as a nice byproduct also bypasses pull-rate limits in Docker Hub. * Full daily copies of the Ubuntu, Debian and Alpine package registries + the most popular PPAs; so you can pin to a specific date (give me the package registry as it was on 2023-12-15). Essentially what snapshot.debian.org does, but fast and highly available (and for more repos). * Full daily copy of the PyPI registry, so you can also pin to a specific date. This has been super useful for resurrecting old Python code. Any Python example w/ dependencies is bitrotted the moment it gets published - StableBuild’s historic registry helps tremendously (see https://ift.tt/UGidqsn ...) * A generic file / URL cache for arbitrary things you need to pull from the internet during builds. This has all been in production with SB’s first customers and has basically eliminated random build failures due to changed dependencies for them. Naturally you still want to upgrade dependencies (security patches are nice!) - but you can do it at their own pace, rather than whenever a container rebuilds. StableBuild is now available for everyone. There's a free Community tier (since today) that gives free access to all services and mirrors (although with a hard 15GB/month traffic limit), and commercial pricing starting at $199 (cheaper than running a high-available apt mirror on AWS - which we used to do at Edge Impulse).
