This sort of thing is true nearly everywhere. In my own career I try to seek out those with the tribal design knowledge and deep understanding and learn as muh as possible.

Here we have an article of bipartisan, uninformed, cherry picked opinions.
mildchalupa··on Buy well, buy once
Honestly it's a fair point. For me it's I don't have enough time to be cheap.

That's the spirit. Everything is a single use item if you are rich enough.

Well you see I have a mortgage and if I walked away they would take everything within the house thus I don't own anything other than the clothing on my back.

Same with the cars.

The total net mortality rate during the peak of COVID were no worse than going back to a day in the the late 90's or early 00's.

So it's interesting. The stated goal of the fed is to keep inflation and unemployment low. As of recently one of the reasons for the inflation is supply chain disruptions stemming from the shutdown of China.

Over the last 13 years the fed has played a much greater role in the market by purchasing securities and setting the discount rate near to zero. The goal being to soften the blow of the housing collapse and to help being the economy back up. What I find interesting about the low interest rate is that low cost lending changes what types of projects are economically viable. If you look at the formula for NPV the discount rate is within the denominator. What this is saying in other terms is that a projects value is manipulated by the discount rate. On the whole low yield capitally intensive projects are possible to take on during a time of low lending costs. Sure the math makes sense here but what does this mean in aggregate. Does it make sense that the value a project supplies to humanity is dependent on the interest rate? No it really does not, it's not required for it to be proportional whatsoever. Capital is just a standardized term for motivation. All that money can buy is someone else's time or effort at the end of the day. What the NPV formula is truly giving us is a ratio of how much human effort will be required and how much output you are likely to get from such efforts.

One of our issues both nationally and globally is that our interest rate is too low, (and we have no way to fairly correct for this). Higher cost of lending prunes projects that are low yield. This prunes projects that are not a large benefit to society. The fed has a hard time moving back to this because of the extreme difficulty everyone would face. Let's say they raise the rates to 18% suddenly homes value must drop to reflect the people's ability to pay the new mortgage rates. Best case this would dramatically reduce worker mobility. Worst case you wipe out the largest asset most might have.

I do believe the fed is used as a tool is used to keep people working. If you track the cost of staples such as a loaf of bread or milk vs the hours required to earn such things on minimum wage you will find that it's all about the same over time. Logically this makes no sense whatsoever. Does this mean that we have gotten no better at producing these commodities over the last 100 years?

mildchalupa··on Ask HN: Why are toggle switches replacing checkboxes? Isn't on/off less obvious?
There are many instances where the default is set at enable fnurbifucation with white text on a black background. Disable is shown as black text on a white background. When you change the state the text and background color inverts.

There is no way of knowing for certain what position is on and what is off without assuming that the first displayed state is on.

I believe recently I setup a nest with this issue. There is no way of knowing what is specifically selected unless there are three options. With three exclusive options you can compare to determine what the current state is because two of them will look the same thus must be off.

Ti-89 93... calculator settings can have this issue but some of the options have 3+ states and once you see the schema it's quite easy to deal with.

mildchalupa··on How we slowed the subway down
One of the things that I find interesting in terms of long lasting standard or infrastructure development is that small variations in design choices early in a system result in radically different performance down the line. For instance the width or guage of a train track will greatly influence the carrying capacity and the size of objects transportable via rail. Same for the size of lane of road. Infrastructure, and standards tend to have an inertia like quality as changeover to a slightly improved system takes significant capital.

In general it seems absolutely insane to me that we rely on an antique control strategy for the Subway while in other industries outside of rail such as aviation or automotive such a system would be easily automated.

Bi phenol's aka plasticizers within plastics.

Endocrine disruptors in plastics are a civilization sized problem.

Every year the plastic micro debris gets smaller and the problems grow larger.

mildchalupa··on The world of pipe fittings
Welcome to the states, we have no laws here. I helped my dad replace our gas lines as a child. I ran the rigid pipe lathe.

There are a few pipe dopes that advertise a wide range of material comparability. I recently purchased some for a automotive racing fuel pump setup that was rated for gasoline, nat gas and water.

Lead free brass is still 0.2% or less. Mitsubishi makes it. "Eco brass".

I'm not sure it's brass anymore without the lead.

Why does it seem that the better a material works the worse it is for humans.

Nearly all homes built in Tucson AZ had a type of plastic that degrades over time resulting in catastrophic failure eventually.

The Teflon tape is only to be used as a friction modifier as NPT and other tapered threads seal on the threads. Reduced friction means that you can get enough load to deform the metal threads and create a seal. Be careful to not add tape to the first 2 threads as small pieces of Teflon tape can break off and get stuck into valves and things within appliances causing them to leak. There is nothing wrong with pipe dope and I find it to be superior though messy.

Annoyance for those in the states: Big box stores used to advertise fittings as NPT (National pipe thread). NPT being an ANSI spec. They seem to have switched to MIP and FIP for Male Iron Pipe and Female Iron Pipe. These are NPT as well but with a new name? Perhaps they are looking to avoid holding themselves to the spec?

Lead content in brass drinking water rated piping and fittings are being phazed out for obvious reasons. New low lead brass is stronger and does not deform as easily as the older leaded brass fittings. The result is that some fittings are now more difficult to tighten untill leak free.

Pex and crimped copper fittings are not without there own issues. Relying on an o-ring with a 30 year shelf life is problematic when the pipe is behind drywall.

Perhaps one day we will get laser welded copper fittings.

It's as though there is a life cycle of an applications development. Early the application is sleek, perhaps not feature rich however instead simple, concise. Either through scope creep, changed ownership or continuous addition of features the application becomes bloated. This could also be the stage of commercialization by way of adds. Finally the application dies as users move onward.

This seems to be fairly common and it seems that as these applications and companies rise and fall that they each bring there own flavor to the mix.

Google maps was concise in 2012, today the app requires a greater number of user inputs to enter a destination for example

I often ponder if there is some sort of heuristic law that determines the level of bureaucracy based on an organization's structure.
