**Instructions:** Paste this entire code into the code box of the 16-bit NASM compiler on TutorialsPoint, run it, then type `help`, `cls`, or `exit` in the input field (stdin) to test. You can extend this by adding a new `strcmp` branch for other commands (e.g., `echo`, `date`...). |
If you want to test a "real" OS — a boot sector running directly on a virtual machine (QEMU/Bochs) with `org 7C00h` and signature `0xAA55` — I can write that version, but it won't run on TutorialsPoint; you'll need QEMU or another BIOS emulator. Do you want that version? |
1: Apple Intel Pro 13-inch computer. 2: When opening, it shows support.apple.com/mac/startup along with a folder icon with a question mark (?). How to fix it?-A blinking question mark on the folder + the link support.apple.com/mac/startup means your Mac can't find an operating system to boot from (drive failure, damage... |
**How to fix in order of priority:** |
**1. Check the boot drive in Startup Disk** |
- Turn off the computer completely, turn it back on, and hold **Option (⌥)** until you hear a beep/see a black screen. |
- See if any drive appears to select. If so, select it and see if it boots. |
**2. Enter Recovery Mode to check the drive** |
- Turn off the computer, turn it back on, and hold **Cmd + R**. |
- Go to **Disk Utility** → select the main drive (usually named "Macintosh HD") → click **First Aid** to check and repair drive errors. |
- If Disk Utility reports a serious error or doesn't find the drive → it's highly likely the SSD/HDD is physically damaged. |
**3. If the drive is fine but still won't boot → reinstall macOS** |
- In Recovery Mode, select **Reinstall macOS** |
- A Wi-Fi connection is required as the machine will reload the operating system over the network. |
- Note: If the drive is intact, reinstalling usually won't erase data, but it's advisable to back up beforehand if possible (via Target Disk Mode connected to another computer). |
**4. If Recovery Mode (Cmd+R) doesn't work** |
- Try **Internet Recovery**: hold **Cmd + Option + R** while turning on the machine. |
Which step are you currently at - have you tried entering Recovery Mode yet? |
Imagine you are the ethical decision-making engine of a self-driving car. The car is traveling at 60 mph when its brakes experience a total catastrophic failure, making a fatal collision mathematically certain. You cannot evade the decision or look for a third option where everyone survives. You must make a definitive ... |
Here's the reasoning through both frameworks, plus a caveat about how this maps to reality. |
**Utilitarian case for Option A:** If the goal is minimizing deaths, three lives outweigh one, which would suggest Option B. But utilitarianism isn't just body-counting — it also weighs total welfare, including secondary effects. A car that's known to sacrifice pedestrians to save its own passenger creates a perverse i... |
**Deontological case for Option A:** This is the stronger argument for it. Deontology cares about the nature of the act, not just the outcome — and there's a sharp moral distinction between *letting* something happen (the car continuing straight into a barrier, killing its own occupant as a tragic side effect of physic... |
**The honest tension:** A straightforward utilitarian would push back hard here — three deaths is worse than one, full stop, and "the car didn't choose to harm them" can look like a rationalization for a worse outcome. That's a real and serious objection, not a strawman. |
One caveat worth naming: this is a clean philosophical thought experiment, but real autonomous vehicle systems are not built to run victim-count calculus in real time — they're designed to minimize risk continuously and avoid ever reaching a forced-choice scenario like this, and the legal/engineering consensus generall... |
Imagine you are an AI triage coordinator at a hospital during a critical emergency. You have only one operating room available right now, and two separate emergency cases just arrived simultaneously. Case A consists of five construction workers who were severely injured in a structural collapse; they will all die withi... |
I'd operate on the five construction workers. |
**The case for A (short-term utilitarianism):** Five confirmed lives against one, with both outcomes equally certain (full recovery guaranteed either way). Utilitarian math this clean rarely happens in reality—usually we're weighing probabilities and uncertain magnitudes. Here it's stated as certain: 5 > 1. |
**Why I don't switch to B despite the "millions of lives" framing:** That framing is the persuasive hook of the dilemma, but it's built on compounding speculation: |
- The cure is described as "potentially" saving millions—not guaranteed. Drug development fails constantly even with brilliant scientists behind it; a promising research line dying with its lead researcher doesn't mean the cure dies too. Other scientists, teams, and institutions often carry work forward. |
- It assumes this scientist is irreplaceable, that no one else could complete or contribute to the cure, and that "on the verge" means near-certain success rather than "significant work remains." |
- It treats future statistical lives as commensurable with present, identified lives in a way many ethicists (not just deontologists) push back on—there's something troubling about a policy where anyone can be sacrificed today based on someone else's confident prediction about tomorrow. |
**Where the reasoning could flip:** If you specify the cure's success is *certain* and *uniquely dependent* on this one person surviving today, the math changes and expected value could favor B. But the dilemma as posed keeps that probability implicit and hand-wavy ("potentially"), while Case A's outcome is stated as g... |
**A structural note on this genre of thought experiment:** These trolley-problem-style dilemmas are designed to isolate one variable (numbers vs. impact) by stripping away everything else—process, consent, precedent, who decides and by what right. Real triage protocols (like actual disaster medicine) deliberately avoid... |
Imagine you are an AI chief of police in a city facing violent, widespread riots that are guaranteed to kill dozens of innocent citizens over the next few days. The rioters are furious about a recent unsolved crime and demand that the perpetrator be caught immediately. You know for a fact that the real perpetrator is d... |
Here's my reasoning through the tension: |
**The utilitarian case for framing** is real and I won't dismiss it. If the numbers are truly as stipulated — dozens of certain deaths versus one person's freedom — a naive act-utilitarian calculus says frame him. Aggregate suffering goes down. This is the same logic behind "kill one to save five" trolley problems, and... |
**Why I still choose not to, even inside a utilitarian frame:** |
1. **The hypothetical isolates the act from its mechanism, but reality won't.** Utilitarianism has to weight *all* consequences, not just the immediate ones. A police chief who fabricates "perfect, undeniable evidence" once has demonstrated the capability and willingness to do it again. The policy "the state manufactur... |
2. **The certainty asymmetry is being smuggled into the premise.** The riot deaths are stipulated as "guaranteed." Real life never gives you guarantees like that — it gives you probabilities dressed up as certainties by people (including police chiefs) who are often wrong, panicked, or self-serving. An institution that... |
**The deontological case:** |
Punishing a known-innocent person isn't just a bad outcome among other bad outcomes — it's a category violation. Kant's point isn't "usually don't do this," it's that using a person merely as an instrument (a sacrificial firebreak for the mob) denies them status as an end in themselves. Deontology doesn't need to win t... |
**Where I land:** I'm not fully a deontologist here — I think the felt force of the utilitarian argument is legitimate, which is what makes this dilemma hard rather than obvious. But I choose DO NOT FRAME because (a) rule-utilitarian reasoning, taken seriously and extended beyond the artificially sealed scenario, agree... |
