I think there's a big qualitative difference between an aircraft that can carry its own power source, and one that needs to be tethered to the ground.

It's not a dumb question, but it's so broad that it would take at least an entire textbook to fully answer it. Just off the top of my head, some possibilities are: * More cores * More numerous/powerful execution units that

It's not as obvious as it could be, because the images were taken from slightly different angles and with slightly different exposure settings, causing a lot of visual distraction. I was able to clean up the animation a little bit: ht

The whole point of something like Little Snitch is to detect, and give you the option of preventing, connections that you wouldn't otherwise know about. For instance, programs that secretly phone home with telemetry about the user&#x

A couple of obvious reasons: - You can apply more flexible rules than just blocking specific hostnames -- for example, based on IP subnets, port numbers, or specific binary executables - You can block connections even from programs that byp

It's not just the pushes themselves; anyone who can create commits or blobs that eventually get merged into your repository, directly or indirectly, can potentially engage in a collision attack. Sure, if you use git with a very close

To illustrate that even more vividly: if a typical lightning bolt is a few km long, the energy released is equivalent to detonating a stream of gasoline roughly 0.1mm in diameter (not much thicker than a human hair).

As discussed extensively in https://github.com/moby/moby/issues/22054 , which is linked from the OP: this doesn't actually help, because Docker (by default) bypasses your existing firewall rules.

Thanks for responding. As far as I can determine, the last deliberate interaction I had with Triplebyte was in May 2020, when I got an email with your name and address on it saying that my profile was about to be made public, and I replied

I appreciate you taking this seriously. If it turns out that it's indeed not a widespread issue, I would take that as a positive outcome because it means fewer people had their data exposed. But I hope you can understand why I'm s

Good to know. Giving them the benefit of the doubt, I can believe that at some point they fixed it so that setting your profile to invisible took effect permanently, but they never went back and retroactively applied that change to people w

Tell HN: Triplebyte is, yet again, making user profiles public without consent?

As far as I know, the JSR-121 proposal was never actually implemented (or if it was, it was never publicly released). The OpenJDK issue is marked as "Won't Fix". https://bugs.openjdk.org/browse/JDK-459943

Unfortunately, trying to defeat side-channel attacks by adding random noise usually only increases the number of samples required to extract information, rather than preventing the attack entirely. (You can blame the central limit theorem f

The capacity of an individual cell doesn't really matter, because you can linearly scale up the energy capacity and power. If you can charge a single cell to 80% in 5 minutes, then you can do the same for many cells simultaneously, as

It doesn't matter whether the cache is co-located with the "client" that ultimately uses the data. Say A is a database, and B1, B2, B3... are memcached servers. The exact same situation applies. > So on update (e.g. when y

Maybe, but if you have a secure enclave that can be trusted not to leak data, then you don't really need PIR. You can just have clients encrypt their queries with a key that can only be decrypted by the code running in the enclave.

Clarification: that was my comment, not OP's. I'm not a cryptography expert, just an interested amateur. But my understanding is that O(n) query times are inevitable if you want information-theoretic security. Maybe it's poss

This has nothing to do with editing Wikipedia. The problem this demo is solving is "private information retrieval" -- that is, you send a query for a particular article, and the server sends back a response containing that data, b

If the source file contains syntax that is invalid on the user's Python version, then your code that's supposed to check the version and throw a helpful exception will never run. Instead the Python interpreter will throw a syntax
