Do the crash reports include recent solar activity?

Do the crash reports include recent solar activity?
- jacquesm 6y agoTimestamp + location should be enough to figure that out.
- ant6n 6y agoIt would be interesting to see whether there is a correlation between solar activity and game crashes — which in turn may provide an indication whether crashes are due to bugs or bit flips.
- joshspankit 6y agoAs long as someone is tracking crash times/locations, the data is definitely there. Working tech support for major ISPs, there were some “surprising” large-queue days that correlated with solar flares.
- cbanek 6y agoWell, I've had to actually worry about radiation bitflips as well. It does happen. But usually not so much on Earth!
- dharmab 6y agoI once got to tell a CTO the reason our shiny new point to point connection was suddenly trash was due to solar flares.
- jgalentine007 6y agoOne of the tire pressure sensors in my car tires had a bit flip a couple years ago and I had to reprogram it's ID. Luckily it was a subaru, so only a light came on in the dash. My old Honda crv however would turn traction control on if your pressure was low - which worked by applying brakes to wheels that were slipping. If you were going up a slippery hill you would soon have no power, sliding backwards nearly off the road in nowhere West Virginia on the way to a ski resort.
- amluto 6y agoHah. My oven’s bottom unit stopped working. I strongly suspect a bit flip.
- jjeaff 6y agoHow in the world would you ever know that problem was caused by a bit flip and not just one of the countless other reasons that a sensor could fail?
- jgalentine007 6y agoI have a TPMS programming tool (ATEQ QuickSet) and reader (Autel TS401), because I like to swap my winter / summer tires on my own. The TPMS light came on one day and inflating tires didn't help - I used the reader and found that one sensor's ID had changed. When I compared the ID (it was in hex) to the last programming - it was a single bit off. I couldn't reprogram the sensor itself, but I was able to update the ECU with the changed ID using the ATEQ. I live in Denver but spend a lot of time skiing around 11k feet, maybe the higher elevation means more radiation.
- dharmab 6y agoSimilar story, we saw that one particular IP address in a public cloud network had a 3% TLS handshake error rate. We diverted traffic and then analyzed with wireshark. We found one particular bit was being pulled low (i.e. 0 -> 0 and 1 -> 0). HTTP connections didn't notice but TLS checksum verifications would randomly fail. Had a hell of a time convincing the cloud provider they had a hardware fault- turned out to be a bug which disabled ECC on some of their hardware. Aside: I'm surprised you got a TPMS programming tool instead of a set of steelies. Big wheels? Multiple winter vehicles?
- jgalentine007 6y agoI have 2 cars. I like the TPMS to work since I've had 3 nails in tires in 4 years (newer construction area). Also the TPMS light in my impreza is almost as bright as the sun.
