GitHits beta 0.9▲181It has been almost 10 years since I started the opencv-python packaging project. Scaling it to more than 100 million downloads as a side project showed me how much ease of installation and proper package distribution matter to users. It gave the computer vision ecosystem a noticeable boost. Now I have a new idea that I hope can help even more people across the broader software engineering world. A while ago, I realized I kept giving the same advice to teammates and friends when they ran into a programming issue they couldn't easily solve: go to GitHub and look at how others solved it. There…

I noticed the growing security concerns around MCP (https://news.ycombinator.com/item?id=43600192) and built an open source tool that can detect several patterns of tool poisoning attacks, exfiltration channels and cross-origin manipulations. MCP-Shield scans your installed servers (Cursor, Claude Desktop, etc.) and shows what each tool is trying to do at the instruction level, beyond just the API surface. It catches hidden instructions that try to read sensitive files, shadow other tools' behavior, or exfiltrate data. Example of what it detects: - Hidden instructions…

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…

Hi HN, we’re the co-founders of Bearer, and today we launch an open-source alternative to code security solutions such as Snyk Code, SonarQube, or Checkmarx. Essentially, we help security & engineering teams to discover, filter and prioritize security risks and vulnerabilities in their codebase, with a unique approach through sensitive data (PII, PD, PHI). Our website is at https://www.bearer.com and our GitHub is here: https://github.com/bearer/bearer We are not originally Security experts but have been software developers and engineering leaders for over 15…

Finally open sourced an internal tool we've been using for managing secrets. It's similar to SOPS, but more opinionated, easier to configure/use correctly, and produces nicer git diffs. It also supports one-way encryption, so you don't have to know the private key to add secrets.

I authenticate to many Git hosts from many machines and got tired of generating and copying personal access tokens. With credential helper git-credential-oauth, there are no personal access tokens or SSH keys to configure. Instead you authenticate in browser using OAuth. Git Credential Manager (included with Git for Windows) has a similar feature but it's awkward for Linux users to install. git-credential-oauth is cross platform and packaged in many Linux distributions.

I got fed up with endless PR reviews and the constant fear of missing a security bug, so I built Shieldcode. What it does: - Scans new pull requests for bugs and vulnerabilities automatically - Comments directly on GitHub with clear, actionable feedback - Works out of the box with no complex setup required Next up: NPM VScan, which will check your npm dependencies on every push for vulnerabilities or malware. I’d love to hear your thoughts and feedback! https://shieldcode.space

Hey HN, Every team I've been on has cobbled together some sort of combination of GitHub branch protections and custom scripts to make sure that PRs conform to organization policies and best practices. Things like: - When {X} file is changed, require review from team {Y} - When a new db migration is added, ensure that a special set of tests pass - Require multiple approvals when the PR is very large - Add a special label to PRs that include breaking changes - Allow emergencies / hotfixes to break glass and bypass all of the above Most teams tend to start out with a little script running…
