I have no experience in PNG encoding, but found https://github.com/brion/mtpng The author mentions "It takes about 1.25s to save a 7680×2160 desktop screenshot PNG on this machine;…

I went to high school in a science magnet program in Texas. Students from 3 high schools were eligible for the magnet program, and the magnet program was housed in one of the 3 hig…

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 s…

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 ag…

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 $…

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…

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 …

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 …

Parler is the right starting their own company in response to Twitter censoring/banning some of their discussions. Parler's current deplatforming indicates that "start your own com…

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…

2015 BS alum Trolling, flicking - I never heard anyone say these, but had heard they were used in the past. Along those lines, flaming or flaming out was used for failing out or ne…

> Intel keeps getting it right with numerical libraries. They're open. They work well. They work on AMD. What Intel numerical libraries are you thinking of? When I think of Intel n…

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…

> It feels as if the point that I'm trying to make is that mindful archiving is a better solution than to just 'keep all the things' On the topic of plain text things (such as text…

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 histor…

Agreed! I'm on an eastern edge of a timezone and DST ending moves sunset forward from 6PM to 5PM (and up to around 4:20PM during winter solstice). This feels like doubling down on …

> a company that is doing serious core refactoring/redevelopment on the back of an underpaid "intern" is probably exploiting that labor in an unfair way > Handing out throwaway pro…

I think of it as a trade-off between the tool perfectly designed for the job and the tool that can be used for the job of which I'm already an expert user. As an example, my curren…

I was an intern at Mixpanel at the time (but not the author of this article or involved in the discussed rewrite). For context, the company was then My recollection of events (of 8…

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…

Deep learning mostly uses matrices with largest dimension Even a 2000x2000 matrix is relatively small as far as non O(N^3) matrix multiplication algorithms go. The faster asymptoti…

Chicago definitely does not "absolutely require" a car. I've lived here for a few years without one, and 80-90% of my friends in the city don't own one. The trains don't go everywh…

This isn't a useful distinction unless you can reliably identify the flaw before the negative impact of LSD. Without a detection mechanism, this is as actionable as "LSD does bad t…

This is the closest to a zero tolerance response to something not clear-cut predatory that I've seen: https://www.facebook.com/Pinegroveband/posts/101557485055597... Musician cance…
