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://bit.ly/3kT2Uu7 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 04:02PM

Show HN: Co-locating Debian Bullseye with an evil maid https://bit.ly/3JmdcMs

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://bit.ly/3Jkl1Cm and here: https://bit.ly/3IWoEx3 Finally, I hope this effort will be useful to others facing similar needs. March 8, 2023 at 10:19AM

Show HN: Path 2.0, a Skilltree for Structured Self-Improvement (You will need to make a (free) account on the website to try out the skilltree.) The Guild of the ROSE is excited to announce the full launch of the Practitioner's Path 2.0, a new framework for structured self-improvement via a carefully-designed skilltree. Founded two years ago, the Guild's mission is to provide structure and community for people interested in self-improvement. The Path skilltree is organized into three branches: - Pragmatist (red): Take direct action, make money, and expand your social network. - Meditative (green): Make art, improve your mental and physical health, and live a good life. - Empiricist (blue): Learn new skills, teach others, run experiments, and think clearly. The user is free to pursue a specific specialization, or to spread their efforts over the three trees. https://bit.ly/3ZC2s1Q March 5, 2023 at 07:12PM

Show HN: I made a chatbot that debugs your code better than ChatGPT I built this using semantic search and the ChatGPT API, which was just released the other day. What makes it special is it not only understands the code you're debugging, but also pulls in additional context like relevant documentation to help answer your questions and suggest code changes. Ultimately, my goal is to take the hassle out of pasting error messages into Google, finding a vaguely related StackOverflow post, and manually integrating the solution into your code. https://bit.ly/41PqmJ6 March 5, 2023 at 02:21PM

Show HN: gpt-graph. A simple, GPT-3 text to entity-relation graph generator https://bit.ly/3L5E0BQ

Show HN: gpt-graph. A simple, GPT-3 text to entity-relation graph generator Hi HN! This is a simple text to entity-relation graph generator, powered by gpt-3 davinci model. The purpose is to feed it actual written data, to obtain a graph representation of entities and relationships mentioned in the text. Also, being able to identify entity attributes like gender, size, age ... My initial goal, was to make it able to process a large amount of text into a big single graph. The problem being the 4000 token limit the model has, I decided to take the approach of feeding the text in batches, and try to merge the incoming graph with the existing information each time. This is done by comparing the incoming node labels with those already in the graph, adding the new information to the existing nodes. This works somewhat, but sometimes entities get duplicated if they are mentioned slightly differently in the text. The comparation method could use some improvement clearly. A nice feature, is that you get to decide what types you want to extract. So if, for example, you are interested only in people, and companies in the text, you can tell the model to stick to that. You can also leave the types to the model discretion. Also, the application allows for saving / loading graphs to json files. These files can be used with Cytoscape Desktop Application, which is a nice side effect of using cytoscape.js. in the UI. I think tools like this can really be of help when going through dense documentation. To have a visual representation of the concepts, entities or whatever, can be really helpful in education, investigation, legal ... Would love to hear your thoughts on how this could be improved. https://bit.ly/41MwYIf March 5, 2023 at 12:47AM
