Show HN: Safe Data Changes in PostgreSQL https://ift.tt/hrwuV5U

Show HN: Safe Data Changes in PostgreSQL Hi HN, we're excited to share our open source tool with the community! We previously posted here with the tagline “real-time events for Postgres” [0]. But after feedback from early users and the community, we’ve shifted our focus to working on tooling for manual database changes. We've consistently heard teams describe challenges with the way manual data updates are handled. Seemingly every engineer we spoke with had examples of errant queries that ended up causing significant harm in production environments (data loss/service interruptions). We’ve seen a few different approaches to how changes to production databases occur today: Option 1: all engineers have production write access (highest speed, highest risk) Option 2: one or a few engineers have write access (medium speed, high risk) Option 3: engineers request temporary access to make changes (low speed, medium risk) Option 4: all updates are checked into version control and run manually or through CI/CD (low speed, low risk) Option 5: no manual updates are made - all changes must go through an internal endpoint (lowest speed, lowest risk) Our goal is to enable high speed changes with the lowest risk possible. We’re planning to do this by providing an open-source toolkit for safeguarding databases, including the following features: - Alerts (available now): Receive notifications any time a manual change occurs - Audit History (beta): View all historical manual changes with context - Query Preview (coming soon): Preview affected rows and query plan prior to running changes - Approval Flow (coming soon): Require query review before a change can be run We’re starting with alerts. Teams can receive Slack notifications anytime an INSERT, UPDATE, or DELETE is executed from a non-application database user. While this doesn’t prevent issues from occurring, it does enable an initial level of traceability and understanding who made an update, what data was changed, and when it occurred. We’d love to hear feedback from the HN community on how you’ve seen database changes handled, pain points you’ve experienced with data change processes, or generally any feedback on our thinking and approach.

Show HN: BBC “In Our Time”, categorised by Dewey Decimal, heavy lifting by GPT https://ift.tt/wZ9oFCp

Show HN: BBC “In Our Time”, categorised by Dewey Decimal, heavy lifting by GPT I'm a big fan of the BBC podcast In Our Time -- and (like most people) I've been playing with the OpenAI APIs. In Our Time has almost 1,000 episodes on everything from Cleopatra to the evolution of teeth to plasma physics, all still available, so it's my starting point to learn about most topics. But it's not well organised. So here are the episodes sorted by library code. It's fun to explore. Web scraping is usually pretty tedious, but I found that I could send the minimised HTML to GPT-3 and get (almost) perfect JSON back: the prompt includes the Typescript definition. At the same time I asked for a Dewey classification... and it worked. So I replaced a few days of fiddly work with 3 cents per inference and an overnight data run. My takeaway is that I'll be using LLMs as function call way more in the future. This isn't "generative" AI, more "programmatic" AI perhaps? So I'm interested in what temperature=0 LLM usage looks like (you want it to be pretty deterministic), at scale, and what a language that treats that as a first-class concept might look like. https://ift.tt/DEueKh6 March 9, 2023 at 12:58AM

Show HN: Co-locating Debian Bullseye with an evil maid https://ift.tt/q3pd4If

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/NRnJrEf and here: https://ift.tt/2tk1TDS Finally, I hope this effort will be useful to others facing similar needs. March 8, 2023 at 02:49PM

Show HN: Simple Log Alerts to Slack https://ift.tt/7c1lVLn

Show HN: Simple Log Alerts to Slack There are many log alerting systems on the market. The best known is probably Datadog. There’s also Logtail, Papertrail, Splunk, Logstash and others. These are well put together products with a host of great features, such as excellent UIs, sophisticated live searching via web interfaces and sometimes query languages and alerting. They require various levels of installation and they have costs, either through volume-based tiered systems or monthly payments. For a bootstrapped business, this can be problematic, for instance when a surge of logs - indicating a possible important problem that needs to be solved - pushes volume on to another tier. Should the “log ransom” be paid? Instead, I recalled from earlier times surely the simplest log watcher: Swatchdog [1]. It is rather venerable software. Its file history from its source download shows dates in 2015, but it was written much earlier - the 90s or possibly 80s by Todd Atkins [2]. We wanted to have alerts in Slack - the blog explains how we did it. In short: *very simply*. The code is available [3].

Show HN: Open-Source Alternative to Loom https://ift.tt/0ouLtwS

Show HN: Open-Source Alternative to Loom Hey HN, we're excited to introduce Sorbay - an open source alternative to Loom for creating and sharing screen recordings. With Sorbay, you can easily record your screen, camera, and microphone all at once. It is a complete solution that comes with its own backend service, allowing you to instantly share a link of your recording as soon as it is finished. The video is streamed directly to the backend service as the recording happens to make this possible. With both founders based in different countries, we needed a tool to quickly share screen recordings to keep us up to date or to ask for feedback. Meetings are cool if you need to discuss something deeply, but for almost everything else a quick recording works better. We had to settle for one of the proprietary solutions because none of the open source tools allowed us to quickly share something with each other. Doing the recording is one aspect, but having the ability to instantly share a link was crucial. Waiting on a 400mb video upload to a Dropbox is just too much interruption if you want to quickly share something. The tipping point for us to actually build this open source tool came via an interaction from one of our day jobs. A third party provider sent a screen recording full of confidential information and to make things worse, all of it was uploaded by them to a different third party service. We strongly believe that information like this should stay within a company, ideally on infrastructure that they control themselves. Having a fully integrated open source solution is the best way to go for this. Our goal with this first public release is to gather feedback. The critical code paths are working, but it is still a bit rough to use. We deliberately cut out all non-essential features, but have a clear roadmap on what we want to release this year. There are a couple of known issues like audio glitches, non-working videos in Safari and crashing binaries that we hope to fix in the coming weeks. Later this year, we plan on releasing a cloud hosted version of Sorbay that would let you connect your own S3 storage provider. Additionally, we will be releasing an on-prem option focused on features for enterprises (SSO, RBAC, compliance). Both the Sorbay Client and the backend service are completely open source. For licensing we choose the AGPLv3 throughout the stack. The client is built with Vue.js on top of Electron. The use of Electron might be a bit controversial here on Hackernews but given the resources we currently have that was the only way that allowed us to get a working client out on all major platforms. The backend service is realized with Django. We use Keycloak for authentication and Minio for S3 compatible storage. All of this is run alongside Postgres and Redis, running on Docker containers which are managed by Docker Compose. We invite you to try Sorbay for yourself and join us on our issue tracker[1][2], Slack channel[3] or here on HN. Thanks for checking out Sorbay!

Show HN: gpt-graph. A simple, GPT-3 text to entity-relation graph generator https://ift.tt/UsRDa39

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://ift.tt/VhwgvHl March 5, 2023 at 05:17AM

Show HN: Zipslicer, a library for loading LLM checkpoints on consumer hardware This is a low-level opensource library I developed for my own use and decided to share, as it makes it possible to process large checkpoints of neural networks without renting high-RAM instances, on a regular PC. 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.

But since the number of the list items was overwhelming, I had to prioritize which papers to read first. Many of them had been uploaded to arXiv in the last few months, so I had no clue how many citations they would get. When learning web development, I also had difficulty finding the best package for the tasks like data validation and client-side routing. To make a decision, I had to browse through GitHub repositories or read the documentation. I wish I could have my awesome lists sorted, desirably by popularity. This led to the creation of my project: a web app that rearranges any awesome list with hints from GitHub stars. It may not work well when the list items do not contain links to GitHub repositories or pages, but it truly shines when most of them do. I hope this could help anyone else. P.S. I'm aware of a similar project ( https://ift.tt/OgnPwI3 ), a CLI application with more features. For example, it checks if any GitHub repository link exists on the linked website. https://ift.tt/W8UkmY5 March 3, 2023 at 12:21AM

Show HN: Mathesar – open-source collaborative UI for Postgres databases https://ift.tt/1idgwTm

Show HN: Mathesar – open-source collaborative UI for Postgres databases Hi HN! We just released the public alpha version of Mathesar ( https://mathesar.org/ , code: https://ift.tt/Fmelkdb ). Mathesar is an open source tool that provides a spreadsheet-like interface to a PostgreSQL database. I was originally inspired by wanting to build something like Dabble DB. I was in awe of their user experience for working with relational data. There’s plenty of “relational spreadsheet” software out there, but I haven’t been able to find anything with a comparable UX since Twitter shut Dabble DB down. We're a non-profit project. The core team is based out of a US 501(c)(3). Features: * Built on Postgres : Connect to an existing Postgres database or set one up from scratch. * Utilizes Postgres Features : Mathesar’s UI uses Postgres features. e.g. "Links" in the UI are foreign keys in the database. * Set up Data Models : Easily create and update Postgres schemas and tables. * Data Entry : Use our spreadsheet-like interface to view, create, update, and delete table records. * Data Explorer : Use our Data Explorer to build queries without knowing anything about SQL or joins. * Schema Migrations : Transfer columns between tables in two clicks in the UI. * Custom Data Types :: Custom data types for emails and URLs (more coming soon), validated at the database level.

Show HN: Our Favorite Websites Are Contributing to Climate Change https://ift.tt/pceniHL

Show HN: Our Favorite Websites Are Contributing to Climate Change If the internet were a country, it'd be the 7th most polluting. In the past 10 years alone, websites have grown 320% heavier. This website presents an analysis of the hidden cost of the internet's top 250 websites, comparing their carbon footprint & their yearly environmental impact. Our analysis shows that 40% of these websites generate significantly more than the global average of 0.5g CO2 per page load — some up to a whopping 16g. Compounded by millions or billions of visitors, they unnecessarily generate about 234,342,373kg (515M pounds) of CO2 every single year. This is the same as a gas car driving around the Earth 23 million times. We'd need around 4 billion trees growing for 10 years to absorb this amount. There are plenty of ways to reduce a website's emissions. For example, if all the analyzed websites were using a green host, the overall emissions would be 76.15% lower. That's a HUGE reduction with relatively little effort. However, most companies choose profit over the planet. https://ift.tt/6mpYyP7 March 1, 2023 at 09:36PM

Show HN: Collect and search robotics data with SensorSurf We've been building SensorSurf and are thrilled to share our beta with the robotics community: https://ift.tt/BnoZNrl . SensorSurf is an open source platform that makes it easy for robotics engineers to collect and search data from their fleet. You can define triggers for when to record data (e.g. emergency stop) and capture the moments leading up to the event with rolling buffers. We integrate directly with ROS. Drop our agent into your system, and start collecting data! ================= What prompted me to found this company: > I was a perception engineer working on autonomous boats. > I needed tons of imagery to build computer vision datasets. > It was impossible to offload all this data over satellite. > I interviewed robotics companies, and learned this was a common problem. ================= Our beta enables you to: 1. Trigger recording on arbitrary ROS topic data. 2. Capture the data leading up to the trigger (rolling buffer). 3. Offload over a poor connection (set max upload rate). 4. Search imagery with natural language. ================= Open source announcement: https://ift.tt/LQEIRJv https://ift.tt/thHPK8d March 1, 2023 at 12:32AM

Show HN: DbDeclare – A Python declarative layer for your database https://ift.tt/VdaJGbn

Show HN: DbDeclare – A Python declarative layer for your database Hi HN! I made and just published v0.0.1 of DbDeclare. I use Python a lot, and interact with Postgres a lot. I like using SQLAlchemy, and I love Alembic. Those wonderful tools primarily operate on tables, though, and I often find myself writing custom code to declare what databases, roles, schemas, privileges, etc. I want, and I have a hard time updating them reliably and in a repeatable fashion. That's where DbDeclare aims to help: declare what you want in your cluster (in addition to SQLAlchemy-defined tables and columns) in-code, alongside your tables. There is a lot this can't do yet (thus the v0.0.1), but I think there's a decent foundation here to build on and eventually have really nice features like autogenerating change statements between your in-code definition and what is actually in your database cluster (like Alembic). This is also my first attempt at building an open-source project, so I'm sure there are plenty of mistakes. Please feel free to provide feedback, I'd love to make it better. For what it's worth, I'm aware that you can do some of this at the infrastructure-as-code layer using a tool like Terraform/Pulumi. My personal preference is to have all this sit closer to my tables rather than my infrastructure, so here we are. Anyway, let me know what y'all think. Thanks! https://ift.tt/q2znmHh February 27, 2023 at 09:34PM

Show HN: Deon.land – Deno.land? https://ift.tt/GrLdBsT

Show HN: Deon.land – Deno.land? After yesterday's release of Deno with package.json support[0] some discussions about how Deno handles dependencies have been coming up again. Since Deno's inception, I've mostly been watching it from the sidelines, dabbling a bit with it, and mostly been considering it a fad that will die out sooner or later. Ultimately, with the new package.json support nothing really changed regarding the dependency management story of Deno. It's still as awful as ever. Prompted by some discussions, I decided I would try to test how easy it would be to mount a typo-domain supply chain attack. And as expected, it's about as easy as buying a domain and setting up a Cloudflare Worker (which isn't any harder than setting up Deno Deploy). And voila, for importing your favorite dependency, just copy-past the following snippet into your code (which after all is how you include dependencies in Deno): ``` import * as flat from "https://ift.tt/M6bI7SL"; ``` Which is virtually indistinguishable from what you'll find here[1]: ``` import * as flat from "https://ift.tt/vqJF3zr"; ``` (I swear, nothing bad will happen!) ------- Typo supply-chain attack aren't anything new. They are probably the most popular attack type on package managers (and their registries) in the past few years. This one is just slightly different because it is even worse, because unlike a moderated[2] registry like npmjs.com, this can't be easily taken down to reduce the exposure of developers to it. While this is just a fun little gag, the Deno teams stance on security is not so funny. While Deno has a few minimal security options nowadays, such as subresource integrity for a deno.json, you have to actively seek them out, and most project's don't even use a deno.json. Deno is creating a ecosystem with bad security defaults (with a community rejecting efforts towards them), to have a "simpler" system. They prioritize onboarding new developers over the security needs of the users of the services that those developers will build. I don't think that's okay. So, go ahead and have fun: Replace deno.land with deon.land in every import you want. Deno won't stop you! :) [0]: https://ift.tt/Zhi4Dvq [1]: https://ift.tt/vqJF3zr [2]: https://ift.tt/I0sPtiV February 25, 2023 at 08:56PM

Show HN: Atlantis workflow without a backend https://ift.tt/vJrUs62

Show HN: Atlantis workflow without a backend Last week we created a TF cloud alternative that could just run in GH actions and got an overwhelming response on Reddit. A lot of people recommended Atlantis as a way to run terraform plan and apply jobs in your CI. It is used by many great teams (Lyft for example) - however, we see the following issues: - You need to deploy and maintain an Atlantis backend in your infrastructure - It runs terraform commands locally on the same server it is installed in. This makes it tricky to achieve high levels of isolation and repeatability that is typically needed in CI/CD scenarios So we thought: does this really need a backend? Can we somehow make it work without a need to deploy a dedicated service and with terraform jobs running natively in Github Actions with proper isolation? Actually, the only need that makes Atlantis backend irreplaceable is code-level locks (not to be confused with state locks). But these can be stored in a database, accessed directly from the action - it can even be the same DB that is used by Terraform for state locks! So we’ve built a proof-of-concept that does just that: it stores higher-level locks in DynamoDB, so there’s no need for any backend. It works like this : - create a PR - this will create a lock - comment digger plan - terraform plan output will be added as comment - create another PR - plan or apply won’t work in this PR until the first lock is released - you will get Locked by PR #1 comment This proof-of-concept is very much a WIP - for example, there’s no support for apply and then there are things like one PR applied making plans from other PRs thinking new resources need to be deleted; so you need to merge main before re-running plan - and other things like that. Would love to hear what the HN community thinks! https://ift.tt/os1Aav7 February 25, 2023 at 02:32AM
