    Hi guys, creator of lockable here - the easiest way to think of lockable is as `flock` for when you don’t have a shared file system. You can use it to control concurrent access to resources or to ensure only a single instance of a process runs at any given time. Your processes can acquire, refresh and release locks via simple HTTP requests, so it’s language/framework agnostic. E.g. with `curl`: $ curl https://lockable.dev/api/acquire/my-lock-name { "response": true //or false, if the lock wasn’t available } $ curl…

    Hi! I got tired of setting up tools I can't explain to a team in a few words like sops or git-crypt, just to store few files with environment variables or secrets, so I built lockenv as a simple alternative. It's basically a password-protected vault file you commit to git. No gpg keys, no cloud, just lockenv init, set a password, and lock/unlock the secrets. This tool integrates with OS keyring, so you're not typing passwords constantly. Should work on Mac/Linux/Windows, but I tested it only on linux so far. I am not trying to replace any mature / robust solution, just…

    I've done this same println debugging thing so many times, along with some sed/awk stuff to figure out which call was causing the issue. Now it's a small Go package. With some `runtime.Callers` I can usually find the spot by just swapping the existing Mutex or RWMutex for this one. Sometimes I switch the mu.Lock() defer mu.Unlock() with the LockFunc/RLockFunc to get more detail defer mu.LockFunc()() I almost always initialize it with `deadlog.New(deadlog.WithTrace(1))` and that's plenty. Not the most polished library, but it's not supposed to land in any commit, just a temporary…
