This is something I've been experiencing as well, and I just started exogenous Ketone supplementation three days ago.


Exogenous ketone supplementation? Are you drinking acetone or something?


Not quite. I've been taking Beta-hydroxybutyrate (BHB) salts in powder form, mixed with water. Here is some interesting literature discussing its benefits as a metabolic regulator of proteostasis in aged and Alzheimer-diseased brains:

https://pubmed.ncbi.nlm.nih.gov/37461525/ (same research article referenced in the post link)

I personally take it to manage brain fog due to long-Covid.


I use that as well. I found that it was a great way to slowly ween myself off caffeine while avoiding the caffeine withdrawals. My sleep is improving a little and I remember more dreams, not sure why.


This is why I come to HN.


Have you tried a ketogenic diet? Ketones from your own fat cells for free.


Interested to know if this ends up helping you long term, thanks.


are you taking BHB along with being on a ketogenic diet or do you else eat carbs?


did it help? also, before covid did you not have brain fog?


Yeah… let’s just strap you to a plunging plane, then invalidate your experience as “overflowing with hyperbole”.


Anything by John H. Holland is good.


Thanks. I have his Hidden Order book and also Per Bak's How Nature Works. Any others you would recommend by these or other authors?


“It's important to understand that in order to make people superfluous, machines will not have to surpass them in general intelligence but only in certain specialized kinds of intelligence. For example, the machines will not have to create or understand art, music, or literature, they will not need the ability to carry on an intelligent, non-technical conversation (the "Turing test"[18]), they will not have to exercise tact or understand human nature, because these skills will have no application if humans are to be eliminated anyway. To make humans superfluous, the machines will only need to outperform them in making the technical decisions that have to be made for the purpose of promoting the short-term survival and propagation of the dominant self-propagating systems.”


What class of problems benefit significantly from being solved by quantum devices?



Yes, but in a large enterprise setting, which is where it makes most sense from a cost standpoint. For smaller business development, I typically go with something like fly.io.


Is there any networking hardware that can intercept and obfuscate payloads that are collected by bossware tools? Also, is there a database of known bossware? I’ve used MITM proxy to intercept web analytics payloads, but I’m curious to know if there is anything available at the hardware level.


Can you share the article you’re alluding to?


Can you elaborate on what you mean by the "Postgres way of doing things"? Also, what is wrong with using Postgres to query data in external object stores? It is a common occurrence for businesses to store parquet artefacts in object storage, and querying them is often desirable.


How does this compare to Hydra? https://www.hydra.so/


You can see performance comparison to Hydra on ClickBench: https://benchmark.clickhouse.com/ by selecting ParadeDB and Hydra. Tl;dr: It is much faster.

From a feature-set perspective, in addition to querying local disk, we can query remote object stores (S3, GCS, etc.), table format providers (Delta Lake, soon Iceberg too).

From a code perspective, we're written in Rust on top of open-source standards like OpenDAL and DataFusion, while Hydra is their own codebase built from a fork of Citus columnar, in C.

Hydra is a cool project. Hope this helps! :)


And when will you have GCS storage ready? I saw on the website that it is not yet available.


Next week (May 20-something)


Very exciting. We use GCS but we don't have a data lake yet. If you were to "sell" the concept of a data lake, what would you refer to as great example usecase?


Thanks for the prompt response, the support for OpenDAL is amazing!


That is one hell of a logo!
