I love this channel, and this was one of the best productions I've seen to date. Having worked in the ICBM development field myself, I'm aware of the phenomenon of Single Event Upsets (SEUs), and what they can do to the operation of a flight computer. The Apollo flight computer used core memory, where bits were stored as magnetic fields in rings of ferrite material. It was inherently "rad-hard", though not because anyone had thought that far in advance. Plated-wire memory, similar to ferrite core memory, has been used in everything from the Peacekeeper (nee MX) ICBM flight computer through the Hubble Space Telescope, the New Horizons Pluto probe, etc, etc.... anywhere that high radiation fields are expected in space, we resort to memory that is 1950s era design. One paper I read recently dealt with the occurrence of bit flips in very large scale super computers. Many people naively think that the "parity bit" check in semiconductors deals with any kind of random bit flips. In fact, bit-error detection and correction firmware algorithms are far more sophisticated than the mere parity bit. But they have limits, especially in huge supercomputers where one is trying to simulate climate on century time scales. Those computers were found to be vulnerable to SEUs at a non-negligible rate, in a way that the built-in error correction firmware could not detect. Climate models solve huge systems of coupled, non-linear differential equations that are known to be highly sensitive to initial conditions. Modelers have tested their software with a trillionth of a degree C change in initial conditions (for a global model), and found that the results were completely different from the original runs. What I have never seen is a global climate model run two or three times, on the same machine, using exactly the same initial conditions, for a century simulation. Most people would say that the results would have to be exactly the same, since computers are determinate machines. But they aren't, as this video shows. I would really like to see such a test be run.

I regularly experienced this just as I was falling asleep and was eventually told that I suffered from sleep cancer - a rare affliction which if left untreated is inevitably fatal (although this process takes anywhere from 1 to 100 years to reach it's conclusion). Fortunately I was cured by a series of treatments that entirely replace sleep with the use of powerful stimulants. I now no longer sleep at all and as a result have been able to hold down a second full-time job as a night-watchman, although unfortunately almost all of the resulting additional income does little more than cover my enormous expenditure on "Red Bull" energy drinks.

About the Camry mystery: it was caused by the air conditioner. I bought a used Camry wagon eons ago and I noticed immediately that when the air conditioner kicked in the RPM increased -- which is a normal thing. But, somehow, a portion of the added power was transferred to the drive shaft and my car would jump a bit forward. It was a manageable problem and I didn't pay much attention to it until... well, until one day our baby sitter used my car to pick up my daughters from daycare and while she was standing at a stop sign, the car accelerated violently and t-boned a passing jeep. Nobody was hurt, the cars were totaled and that was the end of it.

In my work as an automotive engineer I can confirm that functional safety trys to account for random bitflips too. In other words they try to make sure that for safety critical aplications (for example autonomous driving) single bit flips of parameters will not have a critical effect. So if you have a paramenter that says "if this bit is set we are in this state" and this state is safety critical, the bit needs to be on ECC memory (memory that corrects single bit errors). Another way to protect against this is to make sure a single bit flip will not give you correct state of the system because for the state to change always 2 bits need to be changed. So if a single bit is changed, the information stored does not make sense because the 2nd bit is not flipped too. In that case the Software will realize that the information does not make sense anymore and will default into a safe mode. For example in an autonomous vehicle the computer could slow the vehicle down into stop and give control back to the driver when it realizes something went wrong.

There are ways to fix SEU events, in this case application software function to ensure an incremental count for the candidates instead of a glitch count can be done using a glitch filter. Also there is dual memory partition, as instead of having memory cards, alternative storage space within the same computer either external drives or partitioned internal drives can keep another check on the count record to reduce SEU impact. These solutions are routinely in use within control systems of aeroplane gas turbine engines, space propulsion systems and nuclear power systems.

@Chris Kennedy Computers for early lunar missions survived because transistors were so large, thousands of times larger than those now, making them impervious to what were minor disruptions to the amount of current they were switching. In contrast, switching currents of tiny transistors is so small that an energetic particle could easily change its state. Nonetheless, rad-hardened ICs do have specializations such as being built on insulators (eg. sapphire) rather than silicon substrates to reduce those effects. Likewise, computer redundancy (majority voting as he explained) is more than sufficient to make up for the small topographies these days.

Late comment, but back in 2005 when at Ball Aerospace working on the JWST testbed telescope in the clean room, I was integrating the camera systems with the control systems for the optics scientists to use for developing and practicing the telescope alignment process (which they just finished on the real telescope last week). On one of the test images, I saw a streak that as 3-4 pixels wide going across the captured image and persisting for 4-5 frames. Given there was a single laser beam making a very narrow point on the imager in the center, this seemed immensely bizarre. I was a pretty recent grad, so went and asked some of the optics engineers what had happened. Their explanation was a cosmic ray and said that it was really rare to see it so parallel to the image sensor, but not unheard of. I never saw a cosmic array in the imager again, but it was kindof cool to see this kind of effect of a cosmic ray in real life. Just like the memory explanation in the video, the cosmic ray had dumped so much charge onto the pixels of the camera that it took multiple frames for that level of energy to bleed off during the normal read process.

The prius unintended acceleration also had to do with the programming of the ECU in the car. Their programmers were not embedded systems engineers. The design of their operating system was such that the memory would grow and overwrite instructions in running the system. This would have unrepeatable and seemingly random timing and consequences.

I worked on fault tolerant circuits during my engineering studies. SEUs can be mitigated using multiple redundant units and a majority voter circuit. But that too is not free from SEUs, because if there's a bit flip at the output of the voter circuit, that will cause errors in the system. The universe is a cruel mistress indeed.

First I have to congratulate the author of the video, it's excellent! Secondly, I got here because I researched the Net for Bit Flip and the reason for this research was because I saw an episode of NASA's Unexplained Files in which they talked about a malfunction in a component of a space probe and after a lot of analysis on Earth concluded that it had been a Bit Flip in the software. But they speculated that extraterrestrials could have performed that Bit Flip. In NASA's Unexplained Files program, never heard of the interference of these cosmic particles that cause the Bit Flips!?

In 1982 I programmed a memory test for my C64 in ASM as a kid, I did write 0, $ff to all cells and then checked all cells and repeated that. Every other minute to ten a bit failed and the computer produced a little beep. I showed it to friends, even after years they all declared me lunatic. And I knew that these were particle effects, because a professor told us about that at our university at Hamburg, during a "Schnupperstudium", means school classes go to University, that this can happen. I gave that a test. But people prefer to believe in the unfailing computer and to say a different thing is blasphemy. This is now their God and God is unfailable.

@Jeffrey Rock Studio You overestimate my role in X11. Still, if you ask my opinion, yes, there is some stuff bloated in X11 and to put that on a diet isn't a bad idea. But sometimes there are features in a complex system that you'll miss earlier or later. Some of the things X11 can do are overly complex, like round windows, I see that point, but even if that's true our GPU hardware is speeding up considerably and solving the problem en passant. Not that I'm not a manic friend of optimization, you'd find my code everywhere and I pounded some big names out there in the wake of dispute that started harmlessly and ended in total destruction and only barely didn't go nuclear. Still you'll find articles out there where the exploding pieces of Python and why we have to burn it from our boot routines and kernel out there and many more. Still, Wayland I just watch silently. Both sides have their arguments, I just wait for really good code to prove the point, but it hasn't convinced me yet. Wayland programmers are caught in modern programming ideology and with that they start with a bullet they put in their own knee. And with growing complexity of their code these starting conditions and choice of "modern L337" tools will haunt them. That's my two cent on that but I have the privilege to sit in an armchair and watch the mess go nuclear in someone else's living room and I would, before I would even consider to lay hand on that "modern" C++ crap of code (and I won't start on the tool-chain from hell) drill a half inch hole into my right knee and pour sour milk into it and enjoy it, stirring some chili into it with a hot spoon, pour vodka in it and set it on fire and watch it burn, doing nothing but laughing manically. I don't need to provide code to that project and I can live with the idea that others are sacrificing their lives on it. I would have stayed on X and better spent some time into a good remote control and features we really need. It's not that I can't write C++ or my C++ sucks, it is that I have been there and I won't go there a second time. I'm back to C and I would have to elaborate on this decision way over what fits into a YouTube comment. But others did, that do this better than I can. I wish Wayland has the effect they promised. I doubt we will get it, though. We'll just get a lobotomized clone of X that is embedded in an unmaintainable codebase. But that's just my two cent to that. Good enough? I can be wrong, though. I totally can. Not that complete new code bases don't work. Look at VIM and NeoVim, this one man has destroyed all these old men that were sitting lazily on their code base doing nothing but sunning their names in the name of the project. He destroyed them absolutely. One man. But Wayland has no programmers like that, that I have seen. They are all of the new kind. The Python lovers, you know what I mean. They are in that C++ sect, this OOP folly. It goes down the drain and it is only part their fault, it is the fault of their professors. I had such professors too, and I first had to remove all their stupid crap, it took me years. But as I said, I could be wrong. I just hope all this work is not in vein in the end. I, too, want a faster, more efficient GUI. But we are walking the wrong path. See, where I am wrong, I am wrong with C++, they have a C codebase, just checked and I honestly was surprised. A slim hope. The rest is correct, everything done in C++ is doomed. But Python in there. Burn it! Burn it! Burn it! If something has Python in there, everything is lost. Maybe I'm overreacting but I will not join any project with a single line of Python in it. If there is, something is very wrong with the whole project. Because you have to misunderstand something important to let that happen. So I was wrong, but not completely. Python inside, get the Spanish Inquisition. All is lost, launch the star rockets, order the band play on the after deck and mount the rescue vessels. And let it burn.

@Hanno Behrens I just remembered. I was working on a Japanese built machine with high-noise-immunity-logic (HNIL) and used 24V for noise immunity. I was fault finding for a really difficult problem in CMOS with memory addressing, when suddenly the power supply volts dropped to 23.5V (nothing to worry about normally) and the fault appeared!! I found a component that was faulty and now sensitive to supply volts. Mem can be sensitive to all kinds of things and we rely on it to keep the numbers correct in our bank accounts!!!! lol

Vor 3 Monate

Crane Gantry

@Hanno Behrens That's a good full description of the problem. You've obviously given this a lot of attention. I wrote mem-test programs that used a big variety of types of tests. I would even test for mem-cells that I thought could be affected by capacticances between lines running under and over mem-cells for a type of adjacent interference test. Of course I tested for the usual stuff like adjacent mem-cell interference. I often found errors that seemed random and usually put it down to noise on the power supply line(s) 5V or extremely small timing errors in addressing or data reads and writes. But I never found consistency where I could say 'oh that's a timing error' or that is noise of a frequency that is not filtered out in the powersupply. I sometimes considered cosmic rays, after all nothing stops them and they are high-enegry. However you seem to have looked into it thoroughly. Still got your memory test programs? I've got mine somewhere - can't possibly throw them away, I loved that work. Asm is a different world in programming.

Vor 3 Monate

@Crane Gantry Yes, it was done in 6502 ASM of course and to be able to read and write the whole memory I needed to configure the memory or the C64 in the way, that all memory was visible with the infamous 6510 port $01, which was for memory configuration. I also had to stop the "OS" of the C64 to stop the interrupt routines, for there was no "OS" to jump into in that configuration. My routine then used all memory to write $00, then check all memory, write $FF, check after that, write $55 and $AA after that, for it's 01010101b and 10101010b respectively. Because I wanted to make sure that my errors that I measured were not a faulty chip or something or some statistical imbalance in the small capacitors that were used as memory in those days. The computer did a beep when an error occurred and did write bit and memory address to the screen, to make sure it wasn't always the same address or the same chip that produced the error or the same bit (every chip was holding a certain bit). The result was really random and nobody believed me. „Your C64 is broken, mine is working perfectly!“ I brought my program with me and started it on my friends computer: same result. Every run would need a second or two, so the routine used something like eight seconds to run through for each pass. I also tested if the VIC was responsible by turning off the video of the computer and with that stopped interrupting the fetching of bytes from the bus by the video system; it didn't change anything. It was always showing this error. Since them I'm deeply distrusting software in a very professional way. Instead of running several computers at the same time I do fetch and store important bytes into memory several times at several places in memory. I know our computers are failing and that this failing is happening quite often, so how does it come, that they actually work? Why do they work at all? It is the fact that computers are resistant to most memory failing, only some critical will glitch. Check Redcode and Codewars, if you want to know more about that. I can't explain exactly why it is this way, but it is. There has not been well defined scientific research about this issue. Computer Science has gotten ignorant and lazy and ideology is never good for science.

I watched this video when it was released and just ~50 minutes ago my MacBook shut down unexpectedly (first time in 6 years) with no possible explanation, so I recalled what I had learnt from this video (a Random bit flip). I ended up watching the video again, that too in the last third of night.

Love the Video. But i have a question. Is the DNA change through Cosmic Rays based on science or just a Personal assumption/ Artistik choice?
