Long live a Europe of free and sovereign nations.

Makes sense.

As I said, you know your numbers better than anyone else.

I just feel that compute providers often behave as rentiers and I remember the era where a single “webmaster” managed hardware and systems for many services.

You deserve all the success of the world. Good luck.

[Fabio Filasieno ❄️ @FilasienoF]

You know your numbers better than anyone.
But…

It was viable at @dhh scale.

Run the numbers and check used hardware if energy/efficiency is not an issue.

Check financing and national incentives/tax reliefs: in all cases rent for one year is more expensive than buying.

Imagine your profits after few years with full depreciation.

Some do not do it because of the platform building knowledge as its all on them; but that part seems to be already covered 😉

@VittorioBanti Non ha ancora capito che chi ha capito cosa sia l’EU - nonostante la propaganda - è molto difficile da inflenzare con uno slogan.

Si è rivelato ormai da tempo: è un opportunista che fará qualsiasi cosa per stare nella stanza dei bottoni esattamente come la Meloni.

[Fabio Filasieno ❄️ @FilasienoF]

There is great confusion on the topic.

The EU is absolute garbage and It is the political institution that aims to replace nation states with one of the worst undemocratic and bureaucratic systems in the world. The EU will not exist anymore very soon: it’s unsustainable.

Europe is the geographical region and hopefully will be there forever (unless a natural disaster).

This will lead to a few billionaires farming those who receive the infamous “high” income checks. The market will adapt just as it does with incentives: high income will quickly become low income.

This is a nightmare scenario.

The correct path is the pursuit of full employment.

Full employment is the tool that allows workers to negotiate a raise or find a new job (workers become the scarce resource). At the same time, businesses will have a guaranteed rich internal market as everyone has earned income.

All this means security and stability.

Universal HIGH INCOME via checks issued by the Federal government is the best way to deal with unemployment caused by AI.

AI/robotics will produce goods & services far in excess of the increase in the money supply, so there will not be inflation.

There are many similarities with software development.

Fair enough.

I used to disagree with the nationalization of the banking system, but I can’t count how many times the private banking system has committed fraud or used the power to create money to influence the political orientation, of course favoring themselves and capital instead of workers.

Unfortunately there are two choices:
1. Nationalization and get corruption (but the political party will take responsibility).
2. Keep it in the private sector and essentially it’s the banking corporation that rules the country favoring the upper classes (I did not see enough bankers jailed for the disasters that they regularly cause).

I prefer 1.

@VittorioBanti @carlo_minardi1 Buon lavoro.

Spero tanto che i dirigenti capiscano che non è un tema cosmetico, ma è il tema

[Fabio Filasieno ❄️ @FilasienoF]

@VittorioBanti @carlo_minardi1 Lei sa se il Generale ha coscienza dei temi macroeconomici ? In particolare sul tema della sovranità monetaria e la necessaria dipendenza della banca centrale dalla politica ?

Perché sono quasi 30 anni che aspetto; la mia generazione distrutta; ormai si pensa ai figli.

[Fabio Filasieno ❄️ @FilasienoF]

You missed mine; not even 8 paragraphs are enough.

Why focus on asset prices instead of full employment for workers' families and small businesses; and why on earth does the central bank have any other assets other than government bonds?

The financial sector in western countries should just be nationalized and heavily regulated.

[Fabio Filasieno ❄️ @FilasienoF]

The FED holds bonds issued by the government, i.e., a certain class of assets.

The government has to pay interest and repay capital to the asset owner: i.e., the FED.

How: the FED simply tells the government you owe me nothing; I canceled the debt note (bond).

Why: the government does not need to pay interest or payback capital back to the Fed and can, for instance, build a hospital instead. Inflation? None, as all possible inflation has already been generated as the debt money has already been spent by the government.

My point is that focusing on the assets of the central bank seems the stupidest problem in the world to focus on. To be honest, the government can just issue more debt to repay the central bank; again it doesn’t matter.

What matters is full employment, focusing on the well-being of US citizens, providing enough for a decent living and the desire to save by increasing government spending (e.g., building a hospital) and reducing taxes.

Full employment and providing enough for the desire to save by US citizens seems a more important problem than how many assets the FED holds. In fact, one of the main jobs of the FED is to buy assets from the government to fund it.

And I do not know why the FED should own any other class of assets except currencies and government bonds; any asset coming from the private sector smells of fraud.

also @mike_acton "style" has been embedded. 😂

Mike Acton's Rating: 7/10 — "This person clearly thinks about the machine. There are real problems, but the instincts are right."
He'd open with something like: "Most C++ codebases I see, the programmer is writing for themselves. This one is written for the hardware, at least some of the time. Let's talk about when it is, and when it isn't."

@cmuratori For fun I asked Claude if you'd approve... you "vocal" approach as been embedded in Claude knowledge.

I find hilarious the "Casey compatible" code. You should charge Anthropic 😂

No exceptions (-fno-exceptions) — he'd approve
No STL containers in the hot path — he'd approve
Custom allocator over shared memory — exactly his style
Intrusive linked lists — he does this himself
Position-independent handles over raw pointers for shared memory — clever engineering
The cooperative scheduler design with symmetric transfer — good systems work
struct over class — he'd approve
The ib_ prefix convention (though he'd shorten the scalar aliases)
The core architectural decisions are solid and Casey-compatible. His changes would mostly be about reducing ceremony: fewer templates, fewer files, fewer wrapper functions, fewer comments, and killing the stash/ dead code.

[Fabio Filasieno ❄️ @FilasienoF]

All extremely important.

Plus one feature: it should be uniformly encoded to allow future features.

This is an interesting approach:
https://t.co/AHNAig7z5v

Encode structured knowledge as a set of quadruplets down to the proposition level with ALL features that you mentioned.

One minor critique: any data that describes data is by definition metadata (schema is metadata by definition); but it’s clear what you mean: there is no real need to make it some kind of special storage engine for metadata, particularly at agent scale or massive multi-tenant.

A log-structured approach of a simple and uniform self-describing format would be ideal; a metadata format that does not describe itself is useless.

Going up the meta-levels and using a simple “icon” (in ConceptBase a simple fact/proposition) you end up having at the top meta-level a self-describing entity that closes the meta-level recursion.

This might seem a theoretical gimmick, but it’s not, as it allows extensions snd system version updates

While the format might be inefficient, nothing forbids the implementor to build ad hoc systems to “cheat for speed”; but the external user-facing metadata encoding should be “homoiconic” and “axiomatic” like the one presented in ConceptBase, i.e. once specified it can be used to represent any information.

Essentially it encodes the metamodel in itself.

Locking the external user facing metamodel allows the system developers to change the underlying system provided that it complies to the meta-model (particularly important for system version updates).
