I want to know why LOTO protocol wasn't followed.

I cannot imagine how just sitting reading a book is instructional. I would rather see someone do it. Look at the proliferation of youtube videos on how to do basic stuff like change your oil. Some people are visual learners. Those people used to go into trades where as book learners went to college.

A civil engineer could tell you all the theory behind pipe flow but I want a plumber plumbing my house. Someone that learned through hands on visual training.

Programming and coding is on its way to being a trade and it's sad seeing Slashdotters get on the case of people that are visual learners because they can't imagine why anyone would want to watch someone do something.

People that learn by watching?

Some people learn by doing, some people learn by watching, some people learn by reading.

Reading and doing have been covered for a while but.

My coding technique is closer to the shotgun approach where I throw stuff at the wall, see what sticks, peel it off and throw it at more walls. It's hacky but it's how I code. When something is ready for final public release is when it gets documentation and proper indentation.

Just reviewing someone's final proper code won't help me figure out how they got there.

This just reeks of "Old man yells at cloud", just because it's different than how you learned it or do it doesn't instantly make it wrong or stupid.

I'm a mechanical engineer. I could tell you ideas behind how your car works but I wouldn't go near trying to repair it.

What does a CS major specializing in compiler theory need to know about net masks?

You'd be wrong. Car Mechanics have become specialized enough that some of them only work on certain brands of cars. I wouldn't hire a plumber that did residential installs to plumb a hospital. The codes and requirements are completely different.

I'm a Mechanical Engineer and could tell you nothing about how to fix your car. I could tell you how your car worked, theoretically. I couldn't tell you what was wrong with it.

I work with PhD'd engineers that can barely tie their own shoe, but could tell you more about fluid boundary layer conditions than any other human I know.

If you wanted people that knew how to calculate IP ranges maybe you should have hired someone that took some sort of vocational IT training not someone with an advanced degree.

We had an excel VBA that ran our production lines. Talked to Oracle, talked to the hardware test at the end of the line. VBA was responsible for millions of dollars of product going out the door on time.

Because that's what tools the people that designed it had available. It was either that or Matlab but everyone already had Excel and it was 'free' to use.

Now I would love to see something redone in Python.

I don't sell the code I sell the support.

I release everything I work on under BSD and if a company has questions about it I have contact information and an hourly rate available for support. If a company takes it and runs with it (Tivo) then it's not like it was something I was going to get around doing anyway.

If they don't want to pay for support and their product is good enough, a competitor will.

I don't lose out on anything. My code gets used (what I wanted and why I released it) and in 5-10 years if some company wants a subject matter expert I have my contact information and hourly rate available. Beyond that I honestly don't care.

You're decoding it wrong :)

It's like Redditors have discovered how to use the Anonymous Coward account.

And for the years before we regulated NOx? All through the 70s, 80s, and 90s?

Where do you live that this is the case? Pumps have had ULSD since Jan 1, 2007. There were maybe a few exception areas but I think those were all phased out by 2010. They're now moving to ULSD for off highway diesels as well.

Typo, Grant money.

What does anything have to do with genetics? And computers have changed. You don't need a multi-thousand dollar AutoCAD or CATIA license to do modeling.

Why do you post as AC?

At home some of us have garages, shops, driveways. If you can grill meat you can smelt iron.

No one is telling you to do this in your kids bedroom.

With a 3D printer you could run a ~19th century machine shop from your own home. You don't use the 3D printed model. You use it to check fit up and then to turn it into molds.

You can melt iron with used motor oil even charcoal. Sand casting is still used almost everywhere for cast iron.

Give me a 3D printer big enough and I'll build you a tractor. Engine and all.

Who cares? I want my plastic to melt at 105C. I want it to melt at just above room temperature.

I can make molds. Anything I can think up to print I can turn into a mold for metal. With a furnace and some wax I can cast iron.

9L+ diesel engines are still cast. If your bed as large enough you could 3D print yourself a small 2 stroke engine, check for fitup and then build yourself an entire engine from scratch.

"Die Cast" used to be a marker of quality. With a 3D printer at home you can make anything the average machine shop could have made during the industrial revolution.

And because you can do it in 3D with cheap plastic first you can reduce costs. You think a bad 3D print job is expensive? Imagine screwing up a mold design for a 12L engine.
