roye··on Introduction to Locality-Sensitive Hashing
one more, from google: https://ai.googleblog.com/2020/07/announcing-scann-efficient...
roye··on Introduction to Locality-Sensitive Hashing
Academic example but I'm sure it's made it's way to this industry as well: in bioinformatics, this has proven tremendously useful for approximate string matching to do things like identify microbes in sequenced microbiome samples - cf https://genomebiology.biomedcentral.com/articles/10.1186/s13...
roye··on Ask HN: What are you surprised isn’t being worked on more?
how do you compare with substack?
roye··on Filtered coffee may be especially good for heart health

roye··on Extreme Commuting
I wonder how driverless cars will effect this. Similarly I'm wondering if ride-sharing apps already are. Single cars picking up 4 adults that would otherwise be driving could potentially hugely reduce the number of cars on the road, making commutes shorter for all involved.
roye··on Ask HN: What is the most exciting development in your field right now?
Long reads from PacBio, Oxford Nanopore, and 10x are also exciting. This new tech coupled with HiC for scaffolding and single cell sequecing brings up the possibility of complete knowledge of your genome, the collection of strains in a metagenome, or all the types of cells in a tissue/cancer sample.
roye··on Reverse image search
Thinking along these lines I also found this: http://reversedictionary.org/
roye··on A Guide to Deep Learning
I saw stars indicate difficulty; do colors also have some meaning?
roye··on MIT launches new venture for world-changing entrepreneurs
there's also a cornell-technion joint venture called the "Runway startup postdoc" aimed for new PhDs to transition to being founders: http://tech.cornell.edu/programs/startup-postdocs
roye··on Inside the Development of Light, the Tiny Digital Camera That Outperforms DSLRs
strange that Lytro isn't mentioned anywhere, given they developed a product that works similarly.
roye··on As DNA reveals its secrets, scientists are assembling a new picture of humanity
The more relevant continuation of Heng Li's posts is Pall Melsted et al's work on GFA: https://github.com/GFA-spec/GFA-spec

This is pretty close to my area...

roye··on As DNA reveals its secrets, scientists are assembling a new picture of humanity
The main one is vg, which I think Benedict Paten is actively supervising, along with Richard Durbin. The main developer is Erik Garrison. I'm pretty surprised it wasn't mentioned by name: https://github.com/vgteam/vg
roye··on In Newly Created Life-Form, a Major Mystery
Actually there are new approaches to study exactly that, and they are developing rapidly, cf: https://en.wikipedia.org/wiki/Chromosome_conformation_captur... Basically, this problem, along with a long list of other applications is being attacked by deep sequencing. The way it works is that you apply a treatment to DNA that 'glues' 3D contacts in place and covers the glued segment, apply restriction enzymes to cut out what's not covered by glue, get rid of the glue, sequence all that's left, and then map the remaining sequenced fragments to the reference genome. The output is the relative tendency of different regions to come into contact with each other.
roye··on Why Google Wants to Sell Its Robots: Reality Is Hard
It could be that the standard for moonshots changed with the formation of Alphabet. That's the impression I got from yesterday's press coverage.
roye··on Why Google Wants to Sell Its Robots: Reality Is Hard
The mention of groups of robots learning together by exposing themselves to the real world and sharing lessons is very interesting to consider. I wonder if this is inspired by ants searching for food and leaving scent trails. Are there success stories of this approach in robotics already?
roye··on Problems Found at Theranos Lab
Sounds like an accurate description of a ponzi scheme.
roye··on Google Genomics: store, process, explore and share genomic data
I don't think their intent is to replace existing database servers. My impression is that they have copied the data onto their servers to make analysis on their cloud service more attractive. For example, the fact that the 1000 Genomes data is there saves researchers from having to go to the trouble of uploading it themselves.
roye··on Ask HN: What's your favorite online course?
same here, had to watch some of those lectures at 2x speed
roye··on Notes on indexes and index-like structures
Outside of DBs, indexes have shown themselves to be extremely useful in string problems in bioinformatics (my area of research). The modern workhorses of this trend are the Burrows Wheeler transform + FM index (together) and Bloom filters (also mentioned in the link). These have been applied to sequence alignment, de novo assembly of genomes, and compression of sequences. I posit the same bag of tricks can be applied in the NLP/machine learning settings, but I know less about how commonly they have been.

There's a good set of notes touching on this stuff here: http://www.langmead-lab.org/teaching-materials/

roye··on Twitter Expected to Begin Layoffs and Stop Headquarters Expansion
Twitter is actually becoming quite popular in science. It's a great tool to hear of new papers, find out about new findings reported in conferences you can't attend, and communicate in a public forum. Don't think you would have had much of that in MySpace...
roye··on Show HN: Simple Hash Table Implementation for C
It seems like all the hash implementations I've seen have an insertion rate of ~Million/sec. I wonder if it's possible to get at least an order of magnitude faster (single threaded). Are we close to the input string parsing at this rate? Would sorting/caching help a lot?
roye··on A collection of links for streaming algorithms and data structures
I found this set of lectures to be really nice: https://www.youtube.com/playlist?list=PLT_GI2oINs-CRuwMGDa5_... Wish I had time to get through them all...
roye··on Toxoplasma Could Manipulate Our Behavior
Despite the title, I found the details regarding rodent brains and the kiss and spit mechanism much more engaging and convincing than the discussion of effects on humans.
roye··on You can teach a computer to play games, but better that it teach itself
I didn't get much from the linked blurb, but the title made me think: if you sample training data exhaustively and then run a learning process, could you then take the training data maximizing algorithm performance to then better train humans at the same task?
roye··on Israel's water ninja
That's what struck me about it as well. I think things like this along with body/health tracking will be the true IoT killer apps
roye··on Type hinting for Python
sounds like Cython. Are any such optimizations planned for 3.5 (or beyond)?
roye··on Why String Theory Still Offers Hope We Can Unify Physics
This was discussed two weeks ago (https://news.ycombinator.com/item?id=8779532). The title was changed at the source since it was originally too bombastic.
roye··on The Curse of Increasing Marginal Work Utility, or Why I Work So Much
I was also thinking along these lines as I read, and there have been plenty of articles posted on HN on the diminishing returns of working too long. Basically it boils down to people getting tired, and especially in creative pursuits, it helping to get away from your project and let your mind wander sometimes.

What I expected the author might say is that with many accumulated hours you become more efficient such that over time your output per hour grows, but his view seems quite different.

roye··on Software patents are crumbling, thanks to the Supreme Court
Nice development for trivial patents, but it makes me wonder if this could lead to people having to defend their (e.g., algorithm) patents by appeal to computational complexity or the physical constraints of human vs. computer memory, etc.
roye··on Wi-Fi Should Scare the Hell Out of Verizon and AT&T
You reminded me of this: https://news.ycombinator.com/item?id=7771877. (Earlier post of mine, but on topic...)
