    API Jobs, a new job site focused on APIs▲37

    In my spare time to remind myself that I could actually build stuff (and learn some Python, Flask, Redis, etc) I put together a simple job board to feature the best jobs in the API industry. The jobs can be either building APIs at companies like Twilio, Box, Stripe, etc. or integrating them. In addition to featuring those jobs, I'm also aggregating API jobs from GitHub Jobs, Stack Overflow Careers 2.0, and 37signals Job Board. Today I launched with what I would consider an 'MVP' with jobs from SendGrid, TokBox, Twilio, Zencoder, Parse, Stripe, Pusher and Box. Check it out, I'd love to know…

    Open-source alternatives to tools you pay for▲24

    I got tired of collecting open source projects in my chrome bookmarks so I decided to compile a curated list of: - Recently active projects on GitHub - Mostly dev tools (but also productivity, analytics) - Projects which are "Alternative to X software" My bookmarks are finally empty:D If you have a great open source tool you use, I'd be glad to hear your suggestions. Also, any feedback is greatly appreciated.
