Side note, one benefit of ECC RAM is that since it's error correcting it's able to detect when a bit is flipped and correct itself. One of many reasons why servers have such long up times and are so reliable. Error correction comes with decreased speed and increased complexity in manufacturing, it's not something to worry about with your personal computer at home.

20:24 Weird coincidence but there is a case of stall and overspeed warnings at the same time in an actual accident. A speed probe was blocked by a wasp building a nest in it, which made it act as like an altimeter (If you want the science an altimeter can be constructed by having a sealed container that expands as air pressure drops... you measure the expansion and you can work out altitude. A jet's speed senser is a narrow tube with a pressure sensor at the end of it. As the plane speeds up the pressure from the air forced down the tube increases. If you block the front end it instead reads the pressure differential between the ground air pressure where it got blocked and the air pressure at altitude and interprets that as pressure from air being forced through the tube due to airspeed). The higher the plane got the higher its indicated speed. In order to bleed speed the pilots nosed up and reduced power, which lead to the plane climbing, indicating a higher speed, so they nosed up and decreased power... which led to an overspeed and stall warning at the same time.

Why a smaller transistor is better: As used in a computer, a transistor is basically an electronically controlled switch. A transistor has three parts: the gate, collector, and emitter. The state of the transistor (open or closed) is determined by the voltage (or the charge accumulated) on the gate. A smaller transistor has less capacitance (that is, less capacity to hold charge). As a result, a smaller transistor requires less charge on the gate before changing states. If a fixed current is supplied to the gate, a smaller transistor would change between states faster. Alternatively, the transistor could be driven with less current and voltage; this makes each transistor more efficient (thereby reducing the heat generated by each transistor). This latter benefit is absolutely necessary when increasing the density of transistors (since increasing the density of heat generating transistors, without reducing the heat generated by each transistor would cause the CPU/GPU to overheat).

Mostly true, but you mixed up the two types of transistors with regards to their terminals. The classic bipolar transistors used in TTL circuits have a base, collector, and emitter. MOSFETs used in most modern circuits including computers (as well as other field effect transistors like JFETs) have a gate, source, and drain.

Modern memory uses "Hamming codes". They work kind of like parity bits, but with a few hamming code bits you can detect a 2-bit error and correct a single-bit error in a byte. Way more cost effective than duplicate computers.

Most commonly used in server memory, where the need to have reliability is paramount, as most servers never get turned off or restarted for years at a time, many going without a single restart from the day they get installed, till the day a decade or more later, they get retired and scrapped. Can detect and repair single bit errors on a read, and detect 2 bit errors reliable, but a 3 bit or more flip at a single address is hard to reliably detect. However the chance of a single bit being flipped in multiple chips on a stick is very small, so it is reliable enough. Spacecraft use the same memory, but there they add in more parity bits, so that the memory controller can detect and recover from multiple bits being flipped. However they also use generally radiation hardened memory, so memory cells are larger, and also on a sapphire substrate (silicon dioxide) so that charge carriers are harder to generate. As well simply duplicating the computers, and having each one have it's own watchdog timer, that unless regularly reset by the program executing a specific instruction, done by the main control loop, and not an interrupt routine, the processor is reset, and the other one takes control and does the work till the first one is corrected. Space Shuttle 5 main computers, 4 doing the job during launch with them being each redundant with another, and the fifth one just doing telemetry and pretty displays, as it is not a critical thing, the raw data is still shown. in flight each is then reprogrammed to separate tasks, and then again the 4 in pairs for reentry and landing. They never though had a computer fail, not even only the one half of the individual dual redundant computer units. IBM definitely tested them well during manufacture, and till they got upgraded part way through the shuttle life they used core memory as well, resistant to radiation, and also able to store state during power off.

Simon: we need to work on the title. Title: Bit Flips. Me: Clicks on it excitedly.

Even the light hearted episodes fill me with dread. 😂

In the sentence starting at 4:17, I can't believe Kevin left out the phrase "a Toyota recall." Bit flips are a super interesting topic that I've learned about, and I'd say the Toyota case was by far the most consequential. Long story short, a bit could flip in a non-redundant computer system in a vehicle and make the engine respond as though the accelerator was fully to the floor. There's audio of a 911 call from inside a car affected by it, and I'll never unhear that audio (I don't recommend you listen to it). After a few incidents, one with a professional driving instructor at the wheel (not while teaching, but just going about his life), there was a recall and redundancy was added so 2 of 3 bits would need to flip for it to happen again, which has preposterous odds of actually ever happening, considering how rare a single bit flip is.

iirc, scientists aren't entirely sure how pain meds relieve headaches either. Though that could just be an exaggeration or entirely an urban myth.

This disconnect between the positive /negative value and the presence/lack of an electron exists because current was defined before we knew what electrons were. So due to bad luck we established that current flows from the side we called positive to the side we called negative even though electrons moves in the opposite direction.

I work at Microsoft, this is actually a root cause we find for failures on occasion, often enough there’s a template response when it occurs. I’ve had to deliver it to customers before and it’s always an *interesting* time. (Typing before finishing video) That said, there are debates on each case of this happening being a code defect vs a cosmic ray. It’s non-zero in both cases that this can happen. In particular, the election case has a lot of dissenters as they feel a code defect is more likely. There’s also alternatives such as electrons jumping a gate in silicon, which is known to happen. Processors attempt to mitigate this but as you use a processor more it can degrade to a small degree and some gate-hopping would be possible. I high believe this happens but encourage healthy skepticism as without it this can be a canned excuse for failures rather than fixing a bug in code or other issue.

Its actually really hard to get to the Sun. I don't imagine much accidentally heading towards it.

sub-pixels aren't a real thing. It's just what its called when the game is storing the location of stuff more accurately than can be displayed. So if you have a 1920x1080 screen, but the game stores the locations on screen in 4k, every pixel maps to 4 different locations. Data is only this volatile for consoles or really badly programmed stuff, otherwise each piece of memory is isolated by it's address. Basically cos the consoles had no hdd for paging (using the hdd/ssd as if it was really slow RAM memory) so would use the same memory for multiple tasks and sometimes stuff got used for more than one thing :) "If you do get two computers and put them side by side, it's bigger but also twice the computing power" This is only true if you are working on multiple different tasks. Otherwise you get a lot of wasted computations which are basically the two computers making sure they are in sync and allocating the task between them. Most tasks can't be processed in parallel easily. By making them smaller, you can also make them faster as the closer they are together the less you need to worry about propagation delay which is basically caused by the electric not moving fast enough. "Thats not a fast descent" Really worries me anyone is letting you behind a yoke/joystick Simon..... you should know how negative g's work :) It's not rate of descent, it's change of rate of descent that matters.

Anyone who wants more deets should check out an IBM whitepaper on a technique for RAID for RAM. The intro alone widely discusses computer vulnerabilities to cosmic rays...I think the publication date was 1994-ish? Also, ECC memory is designed to capture and correct this type of single-bit flips...once you go beyond single-bit flips, though, it gets much tougher...which was why IBM initially suggested RAID for RAM.

Cool, until Simon's digression I had no idea low-background steel was a thing.

The irishman telling you to turn it off/on is a reference to "The IT Crowd", more specifically actor Chris O'Dowd

I wish Simon would cover video games more on one of his channels

I'm in IT and I have done the turn it off and back on thing and saying I'm doing something on my side. *sip* oh it worked! Excellent.

I'm also in IT, and I'm always reminding my users that "reboot solves a lot of things."

Come here from being in Google pod as Simon said he wants listens up. But. For people who don't know and are interested in speed running content I highly recommend Summoning Salt youtube channel. He does deep dives into some classic games speed runs. And many tricks are found from TAS a tool assistant speedrun that is, basically a human programs a computer to play the game and do exploits and such to find the fastest way possible to finish a game/level. Dunno if anyone actually cares lol good content to get lost in tho
