If you buy higher quality stainless steel (18/10, or 304), those spots don't form, or take many more years to show up.

Wonder if tesla is using 304, or have cheeped out with 430. If it's pitting already, makes me think it's the cheaper option.

I can't find anything more than hearsay about this, but I've now encountered the idea several times that Tesla chose or developed an unusual alloy to mitigate oilcanning, a phenomenon where large, flat pieces of sheet metal tend to cup or bow.

Here's some anecdata that is probably the most coherent read I can find on the topic of Cybertruck oilcanning: http://livingstingy.blogspot.com/2023/08/dude-wheres-my-cybe...

Seems the alloy is probably less rust resistant than more common alloys, and also can't take a clearcoat without losing some valuable properties? More hearsay: https://www.reddit.com/r/teslamotors/comments/197sivs/tesla_...

I appreciate that. As someone with a hobby making software, I can see the need for hiring at some point but I don't even know where to start. Do you just look up one online and call and say "I got a nasty letter, will you be my attorney"? Is there some kind of ongoing subscription cost to keep being "my attorney" or just pay per hour when you have an issue?

For small, transactional dealings where the amount of work is easy to predict, there may just be a fixed fee for that.

For more open-ended work, it is often billed by the hour (time and expense). If the work is non-trivial, they may ask for a retainer, which is a down payment against future hourly work and expenses incurred by the firm.

Another common billing model, called contingency, is generally reserved for cases where the firm is optimistic they will be able to receive a significant monetary judgment or settlement, which they will take part of for their time and effort.

Does anyone know if there exists a tool that can convert tarballs to filesystems and back. I know you can make a loopback device, but it can be pretty hard/impossible to do inside a container, and often requires special flags and privileges.

Looking up comparable ICE cars to a Model Y, google tells me Audi SQ5, BMW X3 M40i, and Mercedes-Benz GLC43.

Their curb weights in lbs are:

Model Y: 4,555

SQ5: 4,288

M40i: 4,392

GLC43: 4,233

So, yes, a model Y is heavier, but only by about 250 lbs. At a 4th power that could be an extra 30% damage compared to an ICE, but even the lightest SUV here is doing something like 3.5x the damage compared to a Honda Civic. So, if you think road damage is a valid concern, electric cars aren't particularly special - SUVs in general should be a bigger worry.

Notably, you've chosen 3 luxury ICE models, and luxury cars are another heavier-than-average group.

chociej commented on Why does the USA use 110V and UK use 230-240V? (2014) electronics.stackexchange... · Posted by u/dilawar

tragiclos · 3 years ago

It's about looking at supply vs demand. Electrical devices are often labeled by the minimum voltage they require to operate. 110 V is commonly used because the device can operate reliably on a 120 V distribution system.

chociej · 3 years ago

It's mostly just a misnomer. A 110 V device with a 5% tolerance, for example, would not work on nominal US circuits.

While it's true, the US does supply 120V±5%, appliances and equipment are operable on a much wider range.

For example, my laptop charger is rated for 100-240V, which is not uncommon.

chociej · 3 years ago

100-240V 50-60Hz switching supplies are common "worldwide" or "universal" adapters, definitely not an indication of service voltage standard here.

This is partially done to compensate for terrible wiring. Lots of people are fond of using small wires and going long distances leading to a lot of voltage drop. They often send 125v or so from the transformer which is 123-124 at the panel, 120 v or so at the receptacle, and >100v after someone decides to run something on a few hundred feet of #18 extension cord.

chociej · 3 years ago

Sure, but the nominal value is still 120 V.

chociej · 3 years ago

Nobody's pointed it out yet, so I'll mention it:

US voltage is 120 V (240 V phase to phase), not 110 V. And while 115 V is within service tolerances specified by ANSI C84.1 (114 V to 126 V), that's not the nominal value.

> . I guess SeaBIOS can't figure out how to assign I/O space to all devices that want some, and so it simply gives up?

It appears that although for some devices VM works fine but for others the VM refuses to boot (esp e100)

So the answer might be more nuanced than it seems?

chociej · 3 years ago

Those devices for which it works fine are such devices that don't request any I/O space

The USA and a few other cultures have unfortunately devalued shame to the point where it holds nearly no cultural power.

Shame is an important aspect of behaviour moderation, a negative emotion usefully experienced when doing something that breaks the social contract.

Devaluing shame instad of targeting the parts of the contract that needed to be changed has cost us a critical tool for self moderation and has created a significant subclass of infantile or openly hostile actors.

Without shame, many people unfortunately need an authority figure to step in and moderate their behaviour. It is an unfortunate side effect of what I can only describe as the infantilisation of society that I have watched happen over the last few decades.

It will likely result in people reaching for a paternal “strongman” figure and a subsequent slide into (probably) fascism.

So long, and thanks for all the fish.

I can't say I agree. The answer to debilitating addiction isn't to make someone feel even worse about it (to the extent they don't already feel terrible). It's to provide meaningful support to get out of addiction and back to the life the person wishes they could have. Shame is fatal to dignity and self-acceptance. It has no place in public health.
