The example cited where they don't know what to return in their `divide` function if a division by zero occurs is nonsense. The answer is simple: let the `DivsionByZero` exception raise! You don't have to return anything! Better y

The project cites this blog post[0] on the "anti-pattern" that is Python exceptions, and I honestly couldn't be turned off on this project anymore after reading it if this is the inspiration behind it. The examples in the REA

It's funny seeing this at the top of HN today. I just wrote a utility in Rust this past weekend to calculate the Shannon and metric entropy of a file ( https://github.com/tuxxy/entropy/ ). I really love the Sha

It would be really nice to have something like this that can run locally but meant for a single user. I don't want to have to log in to my own instance or host a bunch of backend services (or even run it in a docker container). Might b

I'm happy that your experiences with police while homeless were mostly uneventful. However using this anecdotal story as evidence that the police are adequately equipped to play the "social worker" role is exceptionally dange

Does this really even need to be said? Police don't care about the health or the safety of the homeless.

I'm a cryptographer, so I'm inherently curious about secret communication. It just so happens that I'm also very curious about radios, satellite communications, etc. Do you have a link that provides more information on these

Personally, I find the "infinite scroll" to be one of the most devious forms of control developers and product folks have leveraged against individuals. It's extremely manipulative and extremely easy to build. It's just

> everyone is in soup since encrypted data is easy enough to detect... This is only half-true. Any secure encryption is going to result in ciphertext that is indistinguishable from random data. In cases where the ciphertext is designated

Old is entirely a valid critique of crypto; it demonstrates the authors aren't familiar with modern privacy tooling which tells me a lot.

I took a cursory look at the crypto on the backend, and it was mildly concerning. It appears to not be using modern asymmetric primitives. At first glance, it's not insecure or anything... just old[0]. Rather than using something like

What inherently requires an identity to register a domain name?

by tuxxy 7y ago
If anyone is interested, registering a domain is $29.99/year and requires the submission of an identity document (passport, driver's license, etc).

Funny that the Author says counting sort is O(n) when it's really O(n+r). It's almost like making interviews around the knowledge of some case specific sorting algorithm is a bad idea...

This is mostly a research library, so we haven't put our limited effort into CPU operations yet, but it's definitely possible if someone wanted to take the time to expose it in the library.

In most situations, yes. Like I said there are methods and exceptions, but it's complex to get into.

You can do this with a TFHE implementation, if I understand your use case correcltly. You encrypt bits and then you can operate/manipulate on those individual encrypted bits. I referenced NuFHE in a comment, but you should give it a tr

by tuxxy 7y ago
Unfortunately, FHE doesn't work this way. You're operating on encrypted data, so performing some branched operations doesn't work due to the security (IND-CPA) security. IE: You have a value that you need to do `if <condit

If anyone is interested in playing with Fully Homomorphic Encryption, we (NuCypher YC S16) built NuFHE ( https://github.com/nucypher/nufhe/ ). It's written in Python and has excellent documentation, so you can

This is why PrEP is so important and everyone at risk should be on it. We need to spread PrEP use as far and wide as possible.
