Nintendo appears to make the musical elements of its work a priority and it's good to see it escaping the game console into live performance -- following in the footsteps of both show tunes and movie music..
Most of the big TLDs have already converted to algo 13 -- .org is still lingering on algo 8, but .com, .net, .edu, .gov have all converted, so a lot of the DNS traffic is using smaller signatures already.
Well, my reading is that the corrective action was less "add redundant safeties" and more "have sufficient process controls in place to ensure you don't break the feedback loop during pipeline work".
One potential problem with a pressure relief valve as a safety is that it could turn into a flare/blowtorch if there is an ignition source nearby, which constrains where it can be located (and requires ongoing maintenance to ensure vegetation/etc., doesn't build up where it could get torched).

You can see a few shots of the Cuica -- the drum(!) that makes the high-pitched squeaky monkey noises.
Huh. I've owned a few manual-transmission cars over the years and they all disallowed this trick -- pressing the clutch would disengage cruise control just like a tap on the brakes.
But the recommendations to the gas company included:
> Review and ensure that all records and documentation of your natural gas systems are traceable, reliable, and complete. (P-18-7) (Urgent)
> Apply management of change process to all changes to adequately identify system threats that could result in a common mode failure. (P-18-8) (Urgent)
> Develop and implement control procedures during modifications to gas mains to
mitigate the risks identified during management of change operations. Gas main
pressures should be continually monitored during these modifications and assets
should be placed at critical locations to immediately shut down the system if
abnormal operations are detected. (P-18-9) (Urgent)
Edit to add:
This page has currently working links to the specific recommendations:
"According to the NTSB's preliminary report, customers in the accident area received gas from a low-pressure (0.5 psi) distribution network which, in turn, was fed from a high-pressure (75 psi) main pipeline via regulators controlled by sensors measuring pressure in the low-pressure pipes. At the time of the accident, workers were replacing some of the low-pressure piping, but the procedure set out by Columbia Gas for doing this failed to include transfer of a regulator's pressure sensor from the old, disused piping to the new. As a result, when the old pipe was depressurized, the regulator sensed zero pressure on the low-pressure side and opened completely, feeding the main pipeline's full pressure into the local distribution network."
It's more likely that something energetic happened with an onboard system (propulsion or batteries). Could just be leaky valves causing propellant and oxidizer to meet somewhere they shouldn't..
It's had a few propulsion system issues:
> On 9 September 2016, Intelsat announced that due to a malfunction in the LEROS-1c primary thruster, it would require more time for orbit rising ...
> In August 2017, another propulsion issue appeared, leading to larger-than-expected propellant usage to control the satellite attitude during the north/south station keeping maneuvers. This issue reduced the orbital life-time by about 3.5 years.
Odd that the article makes no mention of intel's APX extensions (which add more integer registers, 3-operand variants of most 2-operand instructions, and assorted other tweaks).
According to their web site at https://kairospower.com/technology/ it uses a molten fluoride salt based coolant but unlike the MSR/LFTR designs the fissionable fuel is not dissolved into the coolant; instead, the Kairos reactor design puts the fissionables in pellets that are intended to remain solid while in operation; it looks more like a pebble-bed reactor than a MSR/LFTR.
In August, they said the rocket was ready to fly .. but they were quite visibly still doing significant work to the catch mechanism on the launch tower.
The water deluge system has been in operation for all launches save the first and has been functioning well, protecting the pad from damage. It uses drinking-quality water and outflow has been sampled after each launch, with negligible traces of contaminants detected.
There was a disagreement between the Texas Commission on Environmental Quality and the US EPA about the specific type of permit that SpaceX needed from TCEQ for the deluge system but that was a paperwork/documentation issue only.
First attempt to catch the booster back at the launch site.
The "mechazilla" launch tower has two "chopstick" arms which are used to pick up and stack both stages and which are intended to be able to catch the returning booster and maybe also the returning Starship upper stage.
Wasn't always this way -- see this historic reconstruction of a Baroque orchestra https://www.youtube.com/watch?v=fNqJ8mED1VE (Handel, Music for the Royal Fireworks on period instruments)
Down on the lowest level of the stage we find a small string orchestra, but then behind it on risers there are something like 18 oboes(!!), 10 bassoons, 9 horns, 9 trumpets.
If you transmit, you can be tracked. If you could modify a device to include an explosive, you could also modify it to include an undisclosed transmitter.
