Is there an alternative unroller without ads? Seems like a fun project to build (Yes I have uBlock Origin on my desktop, but I'm not on my desktop)

Try using Nitter. https://nitter.net/tubetimeus/status/1306359385656946688

+1 for nitter.

Actually yes, since they have a huge incentive to Run to Failure. Chaos monkeys would provide a consistent source of failures to make them do their maintenance. Similar to red teams in security.

That makes sense, but can we do it in winter when it is less likely to start a fire?

Isn't the point that starting fires regularly keeps any particular fire small due to lack of fuel (since it has been burned in previous fires)?

Seems like doing it in winter would defeat the purpose.

> With proper engineering This tower looks weird. Overhead three-phase transmission is super common in the EU and I've never seen anything like this "transposition tower" that swaps the wires around in the air and I don't really see why it would make much sense to do so mid-line. Wouldn't it be easier to swap the wires around at the start or end of a line, or inside a substation? Also, as far as I can tell (from some…

Swapping the wires around at the start or end of the line doesn't swap them frequently enough. It's actually quite like a twisted pair in an ethernet cable: you swap the order frequently to average out the different position-dependent electrical characteristics to get a uniform characteristic. The EU probably does that less frequently simply due to higher density, and thus fewer long stretches of transmission line. I…

TIL. Germans of course have their Verdrillschemata to place Verdrillmasten properly, but it seems they're quite rare. There's a Wikipedia article with an example transmission line, but it notes that all Verdrillmasten have been removed from that line over time.

I guess my takeaway from this is if you're a government building some sort of asset you're going to transfer to the private sector, overengineer it. Nobody is ever going to do maintenance, so your thing essentially has to last forever. Imagine that they made the hooks so they only lasted for 10 years -- we'd have 10 times as many billion-dollar fires. But some engineer in 1918 said "you know, let's make it a little b…

Paradoxically though if it failed every 1 year then pretty soon maintenance would have to be performed every few months or days or else there would be so many failures it would be really hard to ignore.

Then they would say "this is annoying, let's make it to last long" which brings us to now...

> With proper engineering and maintenance, PG&E could probably reduce the frequency of fires significantly, but there's always going to be a non-zero risk of fire, both from power lines and other sources, and it seems basically inevitable that one of them would have started another fire at some point. I don’t understand. You’re conceding that if PG&E were a competent and responsible company they could significantly r…

No the root of the problem is that there's too much forest that hasn't burned. Blaming PG&E is missing the actual problem. For instance the Beirut explosion was the fault from the welders causing the explosion. Yes, but the larger and more important issue is why are there so many explosives in the first place? California's mismanagement with it's forest is the same issue. These forests should be periodically burned t…

The policy of not clearing underbush at all just seems ripe for even more wildfires.

Tangential, but Twitter is a very poor medium for delivering this kind of information. It's really a drag for the reader.

I agree. https://threadreaderapp.com/thread/1306359385656946688.html

Nice, but no in-line images which are important in this case.

Couldn't drones + AI do the inspection work more effectively?

Yes. I saw them doing just this in South Korea in 2015. The guys doing it were pretty chill, said I could not take pictures of their drone but they told me a bit about how it worked. Computer vision was part of it, human inspection was too. They said it was much safer than a manned helicopter, and faster.

"Paying money to violate the law" is a fundamentally broken method of law enforcement. Do away with them. Justice should not be a line item in a spreadsheet. Maybe it's only twenty minutes in the county jail but every single infraction should fall personally on the individual who made the decision. Start hauling board members into court in orange jumpsuits and see how quickly these "unavoidable" fuckups stop happenin…

At the same time retribution should not be the goal of justice, it should be rehabilitation. I'm totally against incarcerating anyone not posing imminent threat to life for a multitude of reasons but my most selfish is that locking people up is incredibly expensive and I'd rather not spend my tax dollar on it if its not actually protecting me from anything. US corporate charter exists to exonerate decision makers fro…

The cost of this fire was $85b. If this sort of event could be avoided or mitigated by disincentivising the behaviour that caused it (by putting the occasional exec in prison for negligence) I guess it's likely prison would be quite a bit cheaper overall.

You do go on to agree that there should be disincentives for antisocial behaviour, so I think mostly we agree. Only that perhaps I would consider incarceration a reasonably cost-effective disincentive for such behaviour.
