I like this idea very much. Shameless plug and I don't want to be the Rust fanboy, but I've played with something similar in Rust: https://github.com/julienr/liveboard-rs Basically…

Hey, I'm the lead engineer at Picterra. Would be happy to answer any questions. What we are trying to do is indeed allow customers to build algorithms tailored to their use cases. …

I wonder if some of the classes are just easy to detect objects that they're using to assess the accuracy of the user.

I would guess they have a system such that after a user has passed N captchas successfully, they trust its a human and start displaying them (a portion of) unlabelled captchas that…

I work at Picterra[1], a swiss company doing machine learning on drone & satellite imagery. From discussion with a number of drone service providers, it seems to me the restrictive…

I'm not sure exactly what Netflix means by "if the job breaks", but I've used jupyter notebook in production to do ML before. If you consider the notebook as a way to augment your …

Those are all very good points I didn't think about, thanks for these. I'll fix the two bugs with verify_block and the possibility for a miner to inject invalid a output > input tr…

No good reason for RSA vs ECDSA. I was just more familiar with RSA, but apparently pycryptodome supports ECDSA as well, so I guess the change should be minimal.

Thanks for the precision regarding the hash. Regarding the error, they are logged when a verify_block/transaction returns False, just to be a bit more explicit about what failed. I…

Thanks. You're right about Merkle tree. This is a whole section of the bitcoin paper and it's pretty important. But as far as I understand, it's "only" an optimization to save disk…

OP here. Swapping MD5 for SHA256 is very easy. I'll actually do it - see my other answer above for why MD5. For the other differences to bitcoin and from the top of my head : - In …

Thanks ! The awesome-blockchains is a great resource, thanks for sharing.

Thanks ! I've completely left out communication from this because it wouldn't fit in the notebook and I haven't researched it. Would also appreciate if anybody has good resources o…

OP here. erikb is spot on in the sibling comment. This hasn't been expert-reviewed, hasn't been audited so I'm pretty confident there is a bug somewhere that I don't know about. It…

You forgot to mention that nodes always consider the longest block chain to be the consensus. A 51% (majority) attack is when one miner is able to produce more blocks than the rest…

I don't know about the others, but the two visions dataset they compare to (MNIST and the face recognition one) are small datasets and the CNN they compare to doesn't seem very sta…

I built a small plugin to do that, it's called vim cell mode and provide "send selection to ipython" and "send block to ipython". I find the block mode very useful when developing …

What company are you working at ? Looks like you do some interesting geospatial/map rendering stuff. Are you hiring ? :-)

I can't speak for caffe, but I got a new machine up and running with keras in about half an hour last week without having to compile anything : - install the nvidia drivers, cuda a…
