we built a leaderboard showing which yc startups ship the most by tracking changes in public javascript bundles, we can see which companies are shipping the fastest 🚢 add your startup and see where you rank shipwatch.sh

could also be pretty interesting to have it summarize the javascript changes. pretty useful for watching your competitors. 👀

i wonder how much code exists because an agent didn’t notice there was already a function for that

ciao blacksmith we just made a CI runner so cheap & fast you can scale your CI by 20x on the same budget introducing CI on boat.dev's cloud VMs 1. install boat & run: $ boat ci connect 2. change your runner: - runs-on: ubuntu-latest + runs-on: boat

today we had: - php2shell - a malicious litellm release - node2shell - gitlab unauthenticated rce, cvss 10.0 - railway’s security incident - http/3 attacks happy cybersecurity awareness month to everyone currently rotating a key

“rotate your keys immediately” “also you can’t deploy” yeah wtf @Railway. revoke the old credentials and potentially break production, or leave potentially exposed credentials active while waiting for deployments to return. customers need a way to actually apply the fix you’re asking for

yes, you need a harness to hack at scale but building one from scratch is how you spend six months debugging tool calls, context management, retries, permissions instead of finding bugs start with something like pi and start building off that

Harness is absolutely required if you want to do hacking at scale.

humans picked high level languages because humans had to write and read the code agents don’t care one guy + tokens just rewrote typescript in rust and made it 70% faster many such cases coming

@theoOct 13
ts-rust v0.6.0 is out! It's now 30% faster than before, and up to 70% faster with the new "--fast" mode (at the expense of RAM) This mostly closes the gap in performance against `bun check` while still maintaining 100% compatibility with upstream TypeScript (Bun does not)

our database now has 8,144 findings marked confirmed internally 6,502 are high or critical the bottleneck is no longer finding vulnerabilities it’s reviewing, reporting, disclosing, and getting them fixed
23
14 of our 15 strongest critical samples became materially better after the agent kept going past the first bug one exposed object became crosstenant access one token became control of an entire workflow one weak permission became an admin boundary the first vulnerability is usually just the lead
22
my agent joined a google meet for me today i asked it to set up two new workspace emails for domains we just bought it purchased the accounts configured everything noticed one mailbox was not working contacted google support explained the issue joined a call with a real support employee shared its screen worked through the fix then hung up this is agi 👏

soc 2 might be the purest form of security larp months spent proving you followed your own policies just to ship a badge that makes customers feel safe then someone sends one request to the api and becomes an admin
