As said before, the physics for chemistry is 100 years old (Schrödinger/Dirac), but the N-body Hamiltonian is an exponential beast. Scaling to just 1mg (~10¹⁹ particles) hits the "Exponential Wall."

The app on your Mac today isn't a rewrite of the legendary Mac OS 7.2.1 Graphing Calculator, but an acquired app based on Curvus Pro introduced in OSX Tiger.

The first one has a legendary backstory. 2 devs snuck into Apple after their project was canceled: https://www.pacifict.com/Story/

The disagreement in timelines usually comes from differences in the used definition of AGI. Many who predict a 2026–2028 arrival define it as: 'the ability to perform any purely cognitive task a human can do.' If we stick strictly to that 'cognitive-only' metric, we are arguably very close.

When you explore a problem, use Python and lists/sets/dictionaries/JSON. Wait with types and specific data structures till you have understanding. Speed of development over speed of execution.

When you know what and how to build commit to good data structures. Do the types, structs, classes, Trie, CRDTs, XML, Protobuf, Parquet and whatnot where apropriate. Instrument your program. The efficiency of the final product counts.

If you can do a successful switch to cloud only Entra (aka. AzureAD) first, you are 90% ready for a migration to Open Source. You need Entra for Licensing anyway. Yes, I'm aware that this is hard.

Univention Nubus (Keycloak + OpenLDAP) or FreeIPA as alternatives for Entra come to mind. You can even leverage your Powershell expertise.

Yes and no.

They all have a very solid industrial base, like 30% to 50% of the economy, with ~50% of workers living abroad (not fully part of the welfare state). Comparatively high R&D. Low taxes.

And plain tax evasion is now illegal, but those countries are still an important stop to hide money elsewhere.

But the main secret sauce is a flexible fast legal system. Stability, low crime, and less gridlock in the legislature when the need for change is realized.

Modified Condition/Decision Coverage

It's mandated by DO-178C for the highest-level (Level A) avionics software.

Example: if (A && B || C) { ... } else { ... } needs individual tests for A, B, and C.

3,True,False,False,else branch,B (B flips outcome while A fixed at True)

The history of the Windows TCP/IP stack went most likely like this:

IBM (NetBEUI, no TCP/IP) -> Spider TCP/IP Stack + SysV STREAMS environment -> MS rewrite 1 (early NT, Winsock instead of STREAMS) -> MS rewrite 2 (make win2000 faster):

ZTE is also under scrutiny. The reason it's only Huawei and ZTE is that other Chinese providers are so insignificant that the telecoms will likely be able to replace the infrastructure themselves with spares or consolidation. However, in an emergency, the government would have to foot the bill for replacing Huawei/ZTE systems quickly, as the telecoms couldn't finance this and lack of capacity would mean very high prices.

"Chat Control" is mass surveillance, not targeted Action. Targeted action mayhaps needs some readjustment, but by and large is already easy to obtain for law enforcement.

Normalizing mass surveillance would set a precedent for authoritarian regimes worldwide to demand similar access, further eroding privacy and human rights on a global scale.

I also oppose it on technical grounds, since it would be some kind of local or hybrid ai that does the scanning. A high number of false positives harming innocents would certainly be the result.

There is something to the existence of fads and fundamentals. When I started, it was Object-Oriented-Programming (with multiple-inheritance and operator overloading, of course), Round-Trip Engineering (RTE), XML, and UML.

IMHO, not the ideas were bad, but the execution of them was. Ideas were too difficult/unfinished/not battle-tested at the time. A desire for premature optimisation without a full understanding of the problem space. The problem is that most programmers are beginners, and many teachers are intermediate programmers at best, and managers don't understand what programmers actually do. Skill issues abound. "Drive a nail with a screwdriver" indeed.

Nowadays, Round-Trip Engineering might be ready for a new try.

MS Sidewinder Force Feedback Pro (1997) and Sidewinder Force Feedback 2 (USB). You can buy similar today, but nowhere near the pricepoint. Also the out of the box support by Windows has vanished, and therefore the incentive of game developers to include force feedback.
