Most data centres run *nix yet you have cases like the development of Toy Story 2 that had data loss because someone thought it was a bright idea to give users the right to delete project files. Also data centres would never run Gentroo due to lack of support like they get from IBM (AIX and Red Hat).

HP's Unix is called HP-UX, AIX is IBM.

For features yet all main Unix distros get security and driver updates as fast as any stable Linux distro.

Proprietary SQL: IBM DB/2, Oracle, Microsoft SQL Server
FLOSS SQL: MySQL, MariaDB, Postgres
No-SQL: Mongo, Cassandra, CouchDB, other proprietary shit like elasticsearch.
NewSQL: Google Spanner, CockroachDB
Nu-NoSQL : Terrabase/Skytable, TerminusDB ???

Why the fuck are there so many database companies now? Did people get so butthurt off mysql, etc. not scaling to google scale of billions of users that they decided to fuck off SQL forever? I thought the the nosql craze ended when postgres started offering json store but now I see companies like Skytable, TerminusDB trying to make new databases as well.

Ironically the CTO of TerminusDB used to be a Marxist, Gavin Mendel-Gleason. Even did some interactions with Cockshott. You can still find his blog articles online.

Is there any point of this shit? Properly normalized, tuned, relational DB's with optimized sql queries, indexes, materialized views, and decent replication can probably handle hundreds of thousands of users, and possibly several million users if the hardware is buff enough and you have decent DBAs/database people. This already covers 99% of uses. Also the vast majority of data out there can be modeled relationally, shit like mongo only became popular due to javascript hipsters wanting a dumb json store and not understanding sql/relational db design.

Redis/Memcached are in a different category as in memory db's are often used for caching, or storing session/login data or misc. tokens or something and not as a main data store. So they actually have a use. But the rest of this shit?

Other than a facebook, google, instagram tier service, there's almost no reason to go beyond a traditional relational DB. Maybe some niche company who needs a graph db (social network possibly?) or niche type db for geospatial data or something.

Data involving lots of relationships are a pain in SQL, which is where graph databases are better at. If you ever had to do many-to-many relationships in SQL you know the pain. That's where graph databases like TerminusDB are useful for.

Agree with you about Mongo though. Although I do like it for rapid prototypes.

 No.13645

>>13640
having a ton of many-to-many relationships is a sign of bad design and a need to go back to the drawing board with regards to modelling and alot of the time many to many relationships can be solved using a join table:

What you're saying is true, but what the other anon is saying is also true. AI and massive data lakes are only useful in narrow scenarios but (mis)applied in all scenarios.

And on top of that, there is a lot of mystification of what AI or "big data" actually is and is doing, and enormous amounts of propaganda.

This meme has been around for 10+ years. If anything, it has died down from what it was 8 years ago.
>>13645
>>13640
And also join relations exist for a reason. The idea of tables and relations is a very sound one.

A big trend coming up is application level joins. Especially in the context of "Micro service architecture" but applied to a single API/server. And I hate it. At this point my hate has become so large that I now advocate for as much as possible to be done by the database, and on the application level, use bespoke SQL queries.
>>13250
If you're starting a new project there's really no reason to use mysql over postgres.
Also fuck Mongo and all the stupid fucking trends and those who jump on them.

>stop watching car video half way
>ok you don't want to watch car videos
>watch a video of a girl dancing twice
>ok you want to watch videos of girls dancing
This is such a simplistic way to do it. It's actually kind of bad because if you re-watch the same clip it means you are going to spend more time on that piece of content that you could spend on other pieces of content. Realistically if you wanted to optimize for one metric based on watch time (which by itself is dubious) you'd want to go for something like watching most or all of the clip before moving on. There's also an extremely dangerous assumption built into this about metrics, some real anglo mentality. Just because the algorithm is noticing a pattern and deciding on something doesn't mean the algorithm is correct. It might be very reliable at determining something but that doesn't mean it's doing a good job of interpreting the data coming in. It only knows the metrics that the system feeds it. It doesn't know for example that this guy was so dissatisfied with his experience on tiktok that he raised the issue of the algorithm not doing what he wanted to a techie, who then smugly assured him that it's not a bug but a feature. That's the real scary thing there: not that the algorithm is actually smart, but that so many people will take it on faith that what the algorithm tells you is true.

Currently, the best you can hope for when looking for a secure XMPP client is Pidgin and Gajim, which is not ideal. Aside from rampant security issues and lackluster development/maintenance, there is no integrated OTR and OMEMO support.
Historically, the reason for this disappointing selection has been due to the sabotage of porkies like at AOL or Microsoft who purposefully killed the project so their own software could hold a monopoly.

So, in the spirit of communism, I'd like to propose an autonomous community project for developing and maintaining a client:
- Multiplatform (Linux, Windows, MacOS, iOS, Android)
- Modern, default features for stuff like end-to-end encryption and media sharing, etc.
- Proper delegation of dev duties according to principle of mutual aid. Individuals contribute what they can and the group determines how it fits into the project and how the individual could be supported in their contribution
- Up to date with https://xmpp.org/extensions/
- In-built default OTR, and for groupchats, OMEMO. The client shouldn't generate keys for the user though

Pointless, confusing modularity on the user's end can instead be done for them by a smart, mutualistic development team that are themselves users that want a proper chat client.

Let the ruling classes tremble at a communistic secure chat client!
