Casper da Costa-Luis

casperdcl
London, UK

I've been developing fully open source software (FOSS) for years. The estimated value of my ongoing unpaid work is ~$500/month. For example, I single-handedly maintain tqdm, a world top-20 Python package valued at ~$65k. If you program in Python you've probably used it. I also summarise interesting articles at tldr.cdcl.ml. So far I've only raised-amount in one-off donations in addition to GitHub sponsors. Thanks to the awesome community, I haven't given up yet.

See my profile casperdcl-badge for much more!

If that's not enough motivation: if you sponsor me for $1/month, I will set aside $5/month1 to sponsor others. Yes, your appreciation will be magnified fivefold.

FAQ: I'm a sponsor but not receiving your Jan & July updates

  1. formerly $10/month until March 2023 thanks to @iterative ↩

@casperdcl

Reaching this goal will mean that around 0.05% of people who starred my work also pay for it. I will also be spending $75/month sponsoring others.
