| Mar 10, 2016 at 15:10 | comment | added | SO AI Can Scrape Deez Nuts | Shouldn't this just be closed? It clearly wasn't researched in any way, and is a duplicate of several other questions.If the asker wants to ask his real question, he should edit the title and all to reflect that. | |
| Mar 10, 2016 at 15:01 | comment | added | random♦ | Since none of the questions are answering the bit about the Compute Stick and rehashing the same things about shutting down, this is a duplicate a few times over | |

Duplicate of Is it still necessary to shut down computers?, Why is it not recommended to shut down a computer "brutally" (power switch)? [duplicate] | |
| Mar 10, 2016 at 12:29 | comment | added | Mark Plotnick | The 3B2' s power switch was a double-throw momentary contact switch. Pressing it in the "off" direction didn't cut the power. Instead, it sent a SIGPWR signal to the Unix system's init process, which would initiate a clean shutdown followed by a power down. The only way to do a hard power down, in case the OS wasn't being cooperative, was to yank out the power cord. | |
| Mar 10, 2016 at 11:29 | comment | added | Chris H | @DrZoo it was (still is) identical in XP if you run it on a system without an ATX power supply. I used to use some test kit with a standard XP pro PC built in. | |
| Mar 10, 2016 at 8:21 | comment | added | Daniel Jour | @sawdust Indeed. What I was trying to refer to is that's not as easy to find (pre-built) operating system (images) for such uses. I had to build such systems a while back ... was using a customised Linux distribution run from an (mostly) in-ram squashfs. Regarding TVs and other such customer hardware: Some of these have a small energy storage to keep the main system running until it does a clean shut down. (When you turn them on and off repeatedly, this battery cannot recharge .. ;) ) | |

| Mar 10, 2016 at 4:32 | comment | added | sawdust | @DanielJour --"Such systems are ... rather hard to find, though." -- Not really. There are a lot of TVs, especially the "smart" variety (e.g. Panasonic, LG), and set-top boxes that use Linux or Android (look for GPL disclosure in the owner's manual). They have no user interface for proper shutdown, yet they don't complain about dirty shutdown when started.. | |
| Mar 10, 2016 at 4:08 | comment | added | sawdust | Older hardware was less tolerant of sudden power loss. But modern hardware is tolerant of sudden power loss. Desktop systems tend to require an orderly shutdown. Embedded systems can be tolerant of sudden power loss. Embedded Linux often uses JFFS2 and UBIFS filesystems; "Both UBI (see here) and UBIFS are tolerant to power-cuts, and they were designed with this property in mind.". Note that these are read/writeable filesystems. | |

| Mar 10, 2016 at 3:19 | comment | added | Bob | @LưuVĩnhPhúc Because of the added bit about the Compute Stick. Though none of the answers here directly address that. (e.g. Some machines, especially embedded ones, might be less unhappy about sudden power loss and are designed to cope with it.) | |

| Mar 10, 2016 at 1:08 | comment | added | Daniel Jour | If your hardware supports this and the system you're working with is completely accessing any storage in read only mode and the system is not operating hardware that must be shut down with some procedure (e.g. some TV tuner cards, modems, ... ), then there's no problem just cutting the power. Such systems are ... rather hard to find, though. | |

| Mar 9, 2016 at 21:47 | comment | added | acejavelin | What did your research tell you? A quick Google search for "why do i need to shutdown my computer instead of pulling the power" will find numerous answers... And yes, you can damage your hardware, but the risks are low, but there is a definitely a chance of corrupting or losing data. | |
