     1       True   True   False  True
     2       False  True   False  False
     3       True   False  False  False
     4       False  True   True   True

   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.

   Test #,A,B,A && B,Outcome taken,Shows independence for

   1,True,True,True,if branch,(baseline true)

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

   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.

    A bit of both. Also, the modern Codecs have slightly different tradeoffs (image quality (PSNR, SSIM), computational complexity (CPU vs DSP vs Memory), storage requirements, bit rate) and therefore there isn't one that is best for every use case.

    I have some beef with microsoft, that you can only change this at the Computer level, not per user (see registry key below). Also they call it natural sorting for users, but logical sorting internaly. Unify your termini!

    I haven't read that. But the search for immortality is ancient. It's in the Gilgamesh epic; Emperor Qin Shi Huang searched for it, as did many others looking for the Philosopher's Stone. Of the current wealthy researching immortality, I know quite a few without googling: Larry Ellison, Jeff Bezos, Larry Page, Sergey Brin, Peter Thiel, Sam Altman.

    I would like to know what dystopian books you have read.

    I think about 50 years ago there began a slow shift from warnings of overt totalitarianism (1984, Brave New World, Fahrenheit 451) to threats of social fragmentation, economic inequality, corporate surveillance and other indirect forms of control, the resulting loss of individualism and, of course, ecological collapse. These issues seem to remain relevant for the foreseeable future.

    I also believe that no one really understands how the world works, not even the elites. Incidentally, this is the most powerful argument for democracy that I know of.

    "but it literally does crash and restart" No, think of it not as blue screening and reboot, but as a form of automatic error detection and handling. This keeps the system up and responsive, even if unrecoverable errors happen.

    Possibly because of the Cold War experience. Also because globalisation is slowing down and we see some reshoreing already.

    While I agree with most of the assessment, I think that checkbox is fine. Removing the set of motorized haptic control levers and the motorized steering wheel at the brigde is a problem. Had the designers needed to integrate the feedback forces, they could have visualized them on the gui only stations too.
