There's a very good Brazilian series "Desejos S.A."—literally "Wishes Ltd" but translated into English as "Whatever, whenever". People call a mysterious phone number, voicemail prompt tells them "At the tone, speak your wish clearly", then they get no further feedback and hang up. Shortly after, their wish comes true... and they have to do one task (always incomprehensible to them, often reprehensible) so that someone else gets their wish.
Transparent attempt at whitewashing Boris's image to sell some books. When he got caught hiding millions in assets to avoid paying his creditors, first he tried to bamboozle the judge. Then, he bought a worthless diplomatic passport for the Central African Republic from some guy around the Shepherd's Bush market to claim diplomatic immunity. Then, he strutted haughtily into the courtroom and declined to make any expression of contrition even after having been found guilty.
Judge sentenced him to 3 yr and change in prison; then, just 10 mo later, some tennis-loving Crown servant decided that the way to solve overcrowding in British prisons begun with freeing Boris Becker. A policy for people who'd been in jail for a minimum of 12 mo was inexplicably applied to Boris. He flew to Germany on a private plane, landed and walked, no longer subject to any legal confinement or release conditions.
One can't make this stuff up. Life imitates, and surpasses, art.
Has anyone seen publicly accessible content from the startup-ish MS&E courses? I think Coursera had a MOOCified version of “Startup engineering”, but that was over a decade ago and it didn’t last long anyway. It was great back then.
Clarification question, having read OP yet having missed some fine details: I presume you mean that software could set some CIA-II register to keep the NMI line to the CPU down indefinitely. Since what triggers the handling of an NMI is the transition from high to low, that means no other handler (in particular the Freeze Frame's) would get executed. And one'd also need to redirect the NMI vector, which normally is in Kernel ROM, to a dummy handler consisting of an RTI or little more. Correct?
An addendum: the way you would program the CIA registers to pull the NMI low would most likely be to set up one of its timers on a very short count period (IIRC four system clock cycles is the lowest the chip can do) and make it generate the underflow interrupt. The chip holds the interrupt line low until you acknowledge the interrupt by reading the interrupt source register. If you never get to read it, the interrupt line stays low forever.
I've got valuable advice from SO over the years. There's overlap with LLMs, sure, but it's frequent to have questions that have no answers published anywhere on the web; SO brings people who know out of the woodwork, who create an explanation that didn't exist before. A couple days ago, someone in retrocomputing got to bank-switch a 1983 Radio Shack box... that kind of stuff wasn't published anywhere, until a guy who used to write games for that box answered that question on SO.
Arne has written, as usual, an excellent piece. Not only it argues its intended points, but it can also be followed by everybody-it brings readers up to speed without assuming any significant background knowledge.
In the U.S. system, no visa (including a green card==permanent residency) constitutes permission to enter the country. A visa only enables the holder to travel to a port of entry and request permission to enter the country. That permission may be granted or denied regardless of the specific visa category. Even if you have a gold-plated, von-Neumann-league visa... if the employee at the bottom of the CIS/CBP/* org chart who takes your passport is having a bad day, you'll be on the next outbound flight.
Only U.S. citizenship implies a right to enter the country.
No, LPRs are sort of an intermediate category. CBP can't take away your LPR status, only an immigration judge or court can. So CBP has to let you in although you may be given a notice to appear in an immigration court. Trump discovered this when his administration tried to bar green card holders from muslim majority countries from re-entering the US.
That's a dangerous oversimplification. Say you are a US lawful permanent resident. CBP has the power to deem your LPR status as having been abandoned (e.g., if you've been spending too much of your time outside the US, or established sufficient ties==primary residence in another country) or revoked (e.g., if you've committed one of a variety of crimes, which include any conceivable threat to national security). That determination depends only on the CBP officer having reason to believe that's the case; there's no need for any judge to get involved. Incidentally, many [0] believe that refusing to give CBP full access to the data stored on your personal computing device(s) can constitute sufficient grounds.
Once that happens, CBP can initiate expedited removal proceedings: you are forced into some cell in the airport, without access to legal counsel or any possibility of communicating with the outside world, in some cases without access to the medications you need to take... until it's time for the next flight to the country that issued your passport. Since you've effectively been deported, you can get hit with a 5-yr ban on reentering the US. And you'll have a lot of explaining to do every time you apply for a visa for any country for the rest of your life, because the "Have you ever been deported?" little question is everywhere.
All this could happen, and has happened. (Not going into the side issues of what it takes for visas in various categories to be revoked, or why Trump's travel ban got watered down: which actually happened for a different reason)
Do you have an references for expedited removal being applied to LPRs? That link you included has this:
"Lawful Permanent Residents (green card holders or LPRs): You only have to answer questions establishing your identity and permanent residency (in addition to customs-related questions). Refusal to answer other questions will likely cause delay, but officials may not deny you entry into the U.S. for failure to answer other questions. LPR status may be revoked only by an immigration judge. Do not give up your green card voluntarily!"
Which strongly implies that CBP can't use expedited removal or consider you inadmissable when you apply for entry. You could certainly be detained until you are seen by a judge though (probably not much better) and I've heard of people being pressured by CBP to fill out a I407 (surrendering your LPR status) and then being removed.
