Yea that can’t be true. Otherwise you would be able to systematically modify an existing algorithm to a new one to mirror the Memcomputing method and create new state of the art algorithms that are faster by orders of magnitude? And somehow that hasn’t already been discovered and published and used preferentially to the published state of the art? Nonsense.

Those drives have a sudden flip from 0% corruption to 95-100% corruption when you hit their limits. I wouldn't count that as the same thing. And you can't reasonably expect anything to work on those.

Losing a burst of writes every once in a while also manifests extremely differently from steady 1% loss and needs to be handled in a very different way. And if it's at power loss it might be as simple as rolling back the last checkpoint during mount if verification fails.

I choose Postgres every time, because that is what I am familiar with.

But nerdy stuff:

Postgres stores data linearly (in heap - which has nothing to do with the heap data structure used for sorting, it just means pile of data). If you need to have fast access to data, you need to add secondary indexes - and the secondary indexes point to location in the heap as "this is where you find the data".

MySQL stores data in a tree - a table is a tree sorted by primary key. You can create secondary indexes and instead of a pointer they contain the primary key value.

That means for example that data with similar primary key will be located physically nearby each other, in MySQL but not in Postgres. At the same time, inserting new data with random (like UUID) primary key in MySQL will write all over the table, but will mostly "append at the end" in Postgres.

Postgres also implements MVCC with Serializable Snapshot Isolation - so data that someone changes exists in multiple copies and needs to be cleaned up later - but there's no locking. MySQL relies on locks instead so there's no duplication but you might see transactions waiting for each other. I don't remember if MySQL implements a proper serializable isolation - but that is not really the default on any database anyway.

Interestingly, Oracle has very similar design to Postgres (though it uses rollback segment for old data, so there's no bloat and vacuum but you might get "snapshot too old" error) while MS SQL Server is also tree and lock-based database like MySQL.

Does this impact you? It might, like in cases where MySQL performs terribly due to UUID keys or Postgres can't vacuum fast enough due to high volume of updates or something. Or you're implementing money settlement logic and need proper serilizable transactions, who know. But it is cool to know the implementation details.

Don’t sweat it. I’ve invested multiple hundreds of thousands in venture-backed startups over the past two decades, and lost all of it. None of the startups was successful. These were all audited venture-backed with experienced founders many of whom I’ve known personally in the Austin tech scene. Losing money is the rule in any kind of investing beyond the prevailing real interest rate. It’s all speculation. By the sound of it your diversification is paying off. Actually you’re quite smart in that regard, you didn’t put it all into startups like me.

I find similar societal concern when I tell friends I use Oracle.
Oracle seems to have let what used to be a core
technology of the industry languish

I think slowly squeezing the life from MySQL was a very explicit goal for them. After the big wins (Wal-Mart, etc) MySQL had 15-20 years ago I think it was very clear MySQL was going to chip away at more and more of Oracle's business.

I wonder how much Oracle spends on MySQL every year? They're spending a lot of money to keep MySQL at kind of a "not quite good enough" state. But they can't kill it outright - it'd be like boiling a frog fast instead of slow.

In the end, I wonder what extinguishing MySQL really accomplished for them. It might have bought them some breathing room but Postgres quickly filled MySQL's old segment.
Postgres is >50x slower for range queries(example below) and is akin to using array-of-pointers (ie Java) whereas MySQL supports array-of-struct (C). Illustration from Dropbox scaling talk below.

Sneak peek photo [1] (from [2]). Just imagine its literally 500-1000x more convoluted per B-tree leaf node. That's every Postgres table unless you CLUSTER periodically.

[1]: https://josipmisko.com/img/clustered-vs-nonclustered-index.w...

[2]: https://josipmisko.com/posts/clustered-vs-non-clustered-inde...

Mind boggling how many people aren't aware of primary indexes in MySQL that is not supported at all in Postgres. For certain data layouts, Postgres pays either 2x storage (covering index containing every single column), >50x worse performance by effectively N+1 bombing the disk for range queries, or blocking your table periodically (CLUSTER).

In Postgres the messiness loading primary data after reaching the B-tree leaf nodes pollutes caches and takes longer. This is because you need to load one 8kb page for every row you want, instead of one 8kb with 20-30 rows packed together.

Example: Dropbox file history table. They initially used autoinc id for primary key in MySQL. This causes everybodys file changes to be mixed together in chronological order on disk in a B-Tree. The first optimization they made was to change the primary key to (ns_id, latest, id) so that each users (ns_id) latest versions would be grouped together on disk.

Dropbox scaling talk: https://youtu.be/PE4gwstWhmc?t=2770

If a dropbox user has 1000 files and you can fit 20 file-version rows on each 8kb disk page (400bytes/row), the difference in performance for querying across those 1000 files is 20 + logN disk reads (MySQL) vs 1000 + logN disk reads (Postgres). AKA 400KiB data loaded (MySQL) vs 8.42MiB loaded (Postgres). AKA >50x improvement in query time and disk page cache utilization.

In Postgres you get two bad options for doing this: 1) Put every row of the table in the index making it a covering index, and paying to store all data twice (index and PG heap). No way to disable the heap primary storage. 2) Take your DB offline every day and CLUSTER the table.

Realistically, PG users pay that 50x cost without thinking about it. Any time you query a list of items in PG even using an index, you're N+1 querying against your disk and polluting your cache.

This is why MySQL is faster than Postgres most of the time. Hopefully more people become aware of disk data layout and how it affects query performance.

There is a hack for Postgres where you store data in an array within the row. This puts the data contiguously on disk. It works pretty well, sometimes, but it’s hacky. This strategy is part of the Timescale origin story.

I cannot understate their size. The males are terrifyingly large.

I'd be curious if this would replicate in Elephant Seals but I'm not sure how you could control the positive environment to grow their numbers in the same way
Production MySQL databases of any significant size use pt-osc or gh-ost for schema changes, and these can be throttled, paused, aborted and so on.

I would disagree on maintenance being simpler. I have never had Postgres randomly munge a table and require me to run a command to fix it.
The problem with that argument is that I can still get access to content via subverting said controls. I have access to the underlying infrastructure.

I can't when the entire internet infrastructure is shut down.

Generally it's out of pocket maximum to a point, like $250k. Then it's normally split, something like 80-20, where you have to cover 20% of the bill. That seems like a lot until you have something like cancer, where you need surgery plus chemo in the same year, which adds up quite fast.
NeWS wasn't based on DPS. It's a full display server based on the PostScript Red Book with some extensions (canvases, lightweight processes and sync primitives, events, classes, garbage collection). This allows to write applications in this extended PostScript or in other programming languages, using a preprocessor, such as cps for C or lps for Scheme-48 and Allegro LISP, that generates PS snippets that get sent to the server.

I would also expect some degree of uneven output at lower currents, especially as it ages. But maybe LEDs are more consistently manufactured these days.

You may also experience worse failure modes with the fancier strips that have current limiting ICs instead of resistors.

(Pixel strips can be quite good, too. They seem to mostly have very high PWM frequencies. I assume this is because the electrical behavior is better that way rather than due to any particular care for the pleasantness of using them.)

postgres just because I'm more familiar with it, and the extension ecosystem (TimescaleDB, PostGIS, etc etc).

That said, I'm not going to be sad with MySQL, though I'd probably go with MariaDB just because of full open source (note, I don't know any details there, being a postgres guy)
nice to see it here. while everyone is pouring out throw away shit, synthstrom is transforming their hardware product by software updates since many years, and they still invest in it, instead of abondoning it and selling "new" versions. Sounds like a hot take, but it puts a lot of other companies to shame. Making their firmware opensource is a smart move.

Glad to spread the knowledge, and glad you gave it a shot! It really is that easy, and host headers have been pretty regularly required anyway.

Slightly more interesting is using it to access internal sites, and setting up your own TLS roots and chains for personal or corporate infrastructure.

Credentialing doesn't / shouldn't matter for science. The science should stand on it's own as long as you follow the scientific method, document your assumptions & results, and do work that is reproducible. Bonus points for good peer review. We should reserve the "grains of salt" for people who are sloppy or have been provably bad actors. </soapbox from someone who is "educated as a scientist">
I don’t think it’s a given that finetuning address pretraining bias, most LLMs you would have access to are trained on very similar and biased corpora, see any Anthropic or OpenAI alignment paper.

It’s conceptually possible for extensive finetuning + MoE to work accurately enough for this premise to be feasible but it seems incredibly unlikely with what’s available today.

In any case, using a non-explainable AI model to call individuals racist based on their professional work product (which has significant real-world consequences) is still a horrible idea. This doesn’t carry the same impact as mislabeling tweet sentiment.

Under what possible circumstances will this be the right thing to do? It's already very apparent that the historically unprecedented worldwide Covid lockdowns have had a devastating effect on the prospects of the poorest in society, while seriously enriching the wealthiest (go and take a look at the Forbes rich list, and find someone who has lost money since 2020. You'll have to look very hard).
What’s it do about news worthy content that’s not reported?
Firstly, I don't at all agree that they have zero ability to abstract. Doesn't fit my experience at all. A lot of the tasks I use ChatGPT for is exactly to analyse gaps in specifications etc. And have it tell me what is missing, suggest additions or ask for clarifications. It does that just fine.

But I've started experimenting with the second part, of sorts, not to find plot holes but to have it create character sheets for my series of novels for my own reference.

Basically have it maintain a sheet and feed it chunks of one or more chapters and asking it to output an a new sheet augmented with the new details.

With a 100K context window I might just test doing it over while novels or much larger chunks of one.
