That is a fantastic combination of incompetence and bravado.

Granted, I don't think I'd trust myself not to trip into that thing and get split open myself, so on the rare occasion I need to split wood, I'll stick with hand tools.

There are people who make and use ones like that without much incident, but none of these stupid youtubers seem to notice the large table they build in front of the wheel so they can steady the log before they put it in.

It's not like log splitters cost a lot. A good gas powered one can be had for a few hundred. Then again, rednecks.

I like the giant screw ones you bolt on to the wheel of an old car to split like 18 inch diameter logs 3+ feet long. They seem a lot safer than the big axe wheels.

Next time if there's some nasty screw-up that's not fixed in a reasonable period of time, you may be able to hold your rent in escrow with your local court until they fix the problem, especially if it's a serious safety issue you've documented. Check your state/municipality's applicable laws on this. (I would only do that as a last resort as it's a very provocative move. I'd only pull that if you're not planning on staying there in the long run.)

That varies a lot by jurisdiction. In my state you have to have 2 years residence, 90 days non compliance and there's an annual limit that isn't a month's rent for anything but the shadiest country hovel.

Wow. What state is this? It's like a slumlord's dream come true.

In my state, for minor things a landlord has 30 days to fix it, and then a tenant can pay for the repair themselves and deduct the cost from next month's rent, though it is only up to half a month's rent.

But for major things, like a burst water pipe, (and I'd like to think water leaking through an electrical fixture,) you can just completely withhold the next month's rent after giving them a "reasonable" amount of time to fix it and notifying them in writing. No deatails on what a "reasonable" amount of time is:


Certainly no cost limit for major issues, and none of those "have to have lived there for two years" BS.

Looks like it changed in the last 5 years. Now it's major code violations only, 6 months residence, a written inspection report if the landlord disputes the claim, 14 days notice and the greater of half a month's rent or $300 to fix it yourself here in the great state of Misery.

If you withhold rent for anything less (including not fixing it yourself) you can be evicted.

240V is common on farms and you do need a good multimeter to troubleshoot issues with dryer fans, mills, seed cleaning equipment, etc. It seems like you're always rewiring live cable. You don't have time to find the breaker that could be 100 ft away. You just do it live and make sure that you don't earth. Though you always end up making a mistake.

Yes, 240V hurts like a motherfucker. 110 is like a kiss on the cheek from the love of your life compared to 240. I'd never mess with anything over 240. It's just not worth it unless you're getting paid.

Everyone I ever knew who worked in industry had plenty of stories about people working on 110 whose hands involuntarily clamped down on the lines when they were shocked and died from the prolonged current.

The Therac-25 cases a few years before were pretty interesting. A software bug no one noticed because previous Theracs had hardware interlocks preventing this from happening caused patients intended to get short bursts of diffused 5 MeV electrons to get several continuous narrow beams of 25+ MeV ones. The narrow beams were supposed to strike a plate that would give off x-rays but since they weren't in x-ray mode the target wasn't there and people got cooked in several hospitals from 1985-1987. The net result was over 100 times the intended dose, killing 3 people and injuring several others before the machines were recalled.

Even better, the problem had been reported during development but the engineers blew it off as impossible.

Persistent rumour in those days was that the explosives recipes in that book had been deliberately edited (by THEM, presumably) so they would be dangerously unstable and explode as you tried to make them.

I wonder if any competent chemist or other expert has gone through the book to see if that was actually true.

The original was a bunch of unedited and untested bullshit compiled by some kid out of stuff he dug up in a public library in the late 60s. Hanlon's Razor is in full effect here. A few years ago the FBI released their files on the subject, which you can download in pdf form here. It's mostly responses to concerned letters they received shortly after publication and some memos about whether there was anything illegal about printing it. There's also some discussion about the many copycats online.

The FBI's initial analysis was that "From a technical standpoint, it is for the most part accurate but tends to over-simplify in many instances." The drug chapter is half fantasy and half stuff out of patent applications and chemical journals. The combat chapter is barely enough to springboard your own research. The bomb recipes, while generally correct, are not always complete and thus pose more of a hazard to the attacker than attackee.

Isn't it true that given enough power, anything is a conductor, even rubber?

Hard rubber has an order of magnitude lower resistivity (resistance per thickness) than air at room temperature. It's still something like 100 gigohms for a centimeter thickness but if it can arc rubber won't help. When you get in the hundreds of kilovolts that stops mattering due to air's lower breakdown voltage.

It's not conduction when it's in a vacuum but it's electrons breaking free and travelling through space. It can happen at lower voltages if the metal is hot which was done on purpose in vacuum tube electronics and cathode ray tubes. It can also happen if the metal has a sharp point where the local electric field is strong enough to start pulling electrons off.

Even an ideal vacuum will breakdown and theoretically conduct under a ludicrously high voltage.
