Wow. These videos bring home how insane the rescue was. I could not imagine anyone going through those tunnels with zero visibility and diving equipment, let alone while moving a sedated person along as well. Here the diver's blog post

Parallel prefix sum is the most underappreciated parallel algorithm in my opinion, and this paper is the best explanation and visualization of the concept I've seen. A few years ago I worked on a deep learning project using parallel pr

How much wealthier would you be if you paid no taxes at all in tax year 2020? An example with some made-up numbers that could apply to some HN users: Let's say your net worth was $500K at the start of the year, you earned $200K income

I've found Walmart.com to be about as good as Amazon for my online shopping (in the US). I particularly find Walmart to be a lot better for some dry goods like cereal and Clif bars. They can mix delivery from their warehouses and from

I'm a runner who never goes on an "exercise walk", but there are plenty of (non-injury) reasons someone might prefer walking: - less strenuous - much less fitness required to walk for an hour than to run for 30 minutes - easi

I also find the "or" wording of the law interesting. I do think it's racist as it grants the privilege of abandoning the Jewish religion while remaining a legally privileged class (Jew) to people with some ancestries (Jewish)

Fairness, Accountability, Transparency (aka FAT) is a real sub-field of machine learning, that is as technical as any other machine learning sub-field in my opinion. It is not a PR stunt. I've published at top ML conference a paper abo

I believe there's work to be done for each new CPU architecture (Broadwell, Skylake (AVX-512), Cascade Lake, let alone ARM or other architectures). The code needs to be updated for things like L1 cache size, number of registers per cor

The 30 digit code option is only possible on Android. I agree it's not that bad to do every couple years. There's no way to do backup/restore with Signal on iOS.

Yes. There is no way to move messages from one iOS device to another (such as a new phone). My girlfriend recently got a new iPhone and wanted to transfer our Signal message history from her old iPhone onto the new one. She said it wasn&#x2

The typical neural net matrix multiplication is N_EXAMPLES X N_FEATURES_IN multiplied with N_FEATURES_IN X N_FEATURES_OUT. The output feature count is completely independent of the data size, and input feature count is only dependent on the

Deep learning mostly uses matrices with largest dimension <1000. The size of the matrix directly corresponds to the number of input and output units to to a fully connected layer. Even a 2000x2000 matrix is relatively small as far as non

Most of the time when people talk about "Houston" they're really talking about Houston + suburban sprawl. Pearland to Kingwood is 40 miles. The area is huge, and there aren't common trip starts and trip ends. I'll c
