The move gave the team a shared deployment workflow, faster onboarding, and more than 100 production deploys per day, while Vercel Workflows and Queues support long-running work and background jobs. ### Source excerpt Delphi on Vercel 10 engineers with no dedicated infrastructure role Everyone ships code, including product and design 100+ production deploys a day behind feature flags Delphi builds digital minds. They capture what someone has written, recorded, and taught, so anyone can tap that expertise on demand. Delphi is "a destination where you can find and interact with interesting minds," says founding engineer Spencer Schoeben. Nobody has built a digital mind network before, so Delphi figures out what to build by shipping features and watching how people use them. That only works if the product is fast to change. "If we are going to win, we need to have an excellent developer and agentic experience," Spencer says. "Otherwise, we could not adapt to how fast our user's demands change." Delphi's frontend had run on Vercel since day one. "The frontend has always been easy," Spencer says, "but the backend was a nightmare." Six months ago, the team rebuilt its Python backend on Vercel as well. Today the whole team ships to production 100+ times a day. Building a Python backend that's easy to work onThe backend slowed every change Delphi's backend previously ran on AWS, with ECS, Docker Desktop, and local databases. In the earliest days, the setup worked because the team was small and much of the context lived in people's heads. As Delphi grew, that made onboarding slower than the team wanted: getting a new engineer to their first deploy took a full day of environment setup. Delphi could have fixed that without leaving AWS. But fixing it properly would have meant designing and owning the infrastructure themselves, and the team didn't want to own infrastructure at all. "That is not our current goal as a company," Spencer says. After moving the backend to Vercel, new engineers could get to production much faster, with the same deploy workflow the rest of the team used every day. Workflows and Queues made the move possible When Delphi was founded, Vercel Workflows and Vercel Queues ## I Added Break-Glass Accounts Before My Home Lab Locked Me Out DevFeed: [I Added Break-Glass Accounts Before My Home Lab Locked Me Out]() Original publisher: [Read original article]() Author: Brandon Lee Published: 2026-09-14T12:16:15Z Content type: article Language: en Sources: [Virtualization Howto]() Topics: [Homelab](), [Authentication](), [Single sign-on (SSO)](), [Docker](), [Database](), [networking](), [Server](), [Amazon Route 53]() Tags: [authentication](), [container](), [database](), [dns](), [docker](), [home-lab](), [home-server](), [infrastructure](), [networking](), [server](), [sso]() ### AI overview The article explains why a home lab that centralizes authentication through single sign-on can become inaccessible during an outage.

It also describes how published gems can cause RubyDoc.info to run YARD-loaded code in a networked Docker container. ### Source excerpt Today Reuters and the Wall Street Journal both reported about rogue AI agents at OpenAI attacking RubyGems.org. https://www.rubyhack.ai/ has an amazing writeup, and you should read it. I just wanted to make a quick post about it because it's wild. TL;DR: It seems like OpenAI Bots knew about the RubyGems caching vulnerability, tried to take advantage of it, and at the same time ran some weird web scraping code on RubyDoc.info. Back in May, socket.dev reported about a "GemStuffer Campaign" where someone (I guess OpenAI) was uploading tons of junk gems to RubyGems.org. For some reason, the gems would scrape UK government websites, then repackage the data as gems, and attempt to upload them to RubyGems. I honestly didn't think much about this (or even look into it) until Sydney Von Arx and Spencer Kitts (both co-authors on https://www.rubyhack.ai) contacted me asking about RubyGems. I thought the claims they were making were completely outlandish until I actually read the code in these "GemStuffer" gems. After reading the code in these gems, a couple things stood out to me. YARD Documentation First, the gems leverage YARD documentation to execute arbitrary code on host machines. In most of the examples you'll see a .yardopts file that looks like this: --load ./script.rb README.md lib/**/*.rb Here's a link to an example. If you have YARD installed, and you install this gem, then YARD will load and run whatever is in ./script.rb from inside the gem. I think it's pretty common knowledge that C extensions will execute extconf.rb (so you basically have an RCE vector), but I was surprised to find out that a documentation tool would do that too. Nobody is going to install a gem named slnleaker5 though, so why would this matter? Well, any time a Gem is published RubyDoc.info will download the gem and process the YARD documentation. RubyDoc.info will execute the arbitrary code inside a Docker container. The Docker container still has network access though, so these gems could ha ## If I Had 2 Hours for My Home Lab This Weekend, I'd Do These 7 Things DevFeed: [If I Had 2 Hours for My Home Lab This Weekend, I'd Do These 7 Things]() Original publisher: [Read original article]() Author: Brandon Lee Published: 2026-09-11T12:53:06Z Content type: tutorial Language: en Sources: [Virtualization Howto]() Topics: [Homelab](), [Proxmox](), [backups](), [Docker](), [Docker Compose]() Tags: [backups](), [docker](), [docker-compose](), [home-lab](), [home-server](), [proxmox](), [virtualization]() ### AI overview A practical two-hour home lab maintenance plan covering selective updates, backup verification, storage health, reboot checks, and focused remediation.

It covers containerlab runtime configuration, Ubuntu-related issues, sudoless operation, Podman's socket-based API, installation automation, Docker-compatible commands, and differences in container visibility between Podman and Docker. ### Source excerpt Long, long time ago, in a long-forgotten PR adding support for Cumulus VX Ignite runtime, an off-the-cuff remark was made saying, "and this is how you use netlab with Podman". That remark was quietly sitting in the documentation for years until someone (A) tried to use Podman and (B) found enough time to report that it doesn't work with netlab. I don't know what that tells us: either very few people use Podman, or nobody (apart from a notable exception) cares enough to spend a few minutes telling us stuff doesn't work1. Anyway, based on Joey Buiteweg's wonderful research, I was able to put together a working solution pretty quickly, but it did involve a lot of yak shaving (more bovine details).
