I am sure english will remain the dominant language for a while but I wonder if it makes sense to start learning new (human) languages just to open up the number of communities you can learn from?
You can't have the rate of publication be a logistic function and the cumulative publication be a logistic function. The derivative(i.e., rate) of the logistic function should be 0 at both tails which isn't S-shaped anymore.

Do you have links (or just keywords) to learn more? Will I need to add something like Cloud Pub/Sub to my stack? https://cloud.google.com/solutions/using-cloud-pub-sub-long-...
This is more complicated than I imagined so I am not sure the cost saving will still work out (factoring in development time and extra code maintenance cost).
You can argue that the user can upload anything using the original api anyway. But in the original case you can do server-side validation before the upload is proxied. I am thinking stuff that are domain specific like only allowing videos that are 6 seconds long or something.
You can move the validation to the client but the client can be easily modified. An actual user might not do this but someone trying steal your storage space (for serving malware or something) might?
These signed urls also seem to expire based on time so you can potentially save the url and upload again later if you allow generous expiration. (again, not really something I see being a huge problem)
But I guess these aren't really serious issues compared to the cost savings. Am I missing other ways this can be exploited?
I am looking into the GCS version, not S3, if that matters: https://cloud.google.com/storage/docs/access-control/signed-...
How do you make sure the company won't just take your advice and hire a guy to do this for 90k/yr instead of letting you work on it for three weeks?
- Each value generates a sequence of coin flips
- Count the number of consecutive heads until you hit your first tail
- Take the longest streak amongst all your values, call it n
- Report 2^n as your estimate
This works because if you only have a few people flipping, you won't get a lot of long streaks.
But if you had lets say 1024 flippers, you expect to see one person flip 10 consecutive heads.
Coins flips here are just the bits generated by hashing the value so each coin flip sequence will be the same for each value.
I have been using reddit for probably a decade now but don't remember ever clicking an ad. OTOH I typically misclick on a few links before I get my download when visiting pirate sites even with adblock on.
Conceptually hyperloglog should be really simple (count leading zeroes) so I wasn't sure what there was to "maintain".
Looking at the citus repo it seems like they made a lot of interesting improvements to the original algorithm: https://github.com/citusdata/postgresql-hll
Interesting how fitting a simple theory work to the real world takes 3.3k lines of code.
The privacy is worth it.
