Apples and Oranges. Forgot to take the pill was you didn't do something because you forgot and so it couldn't protect you.

Valve not closing all the way happens all the time when you think you closed the valve all of the way and it didn't seat properly so you tried and the equipment failed.

The pill has an extremely low rate of failure when taken properly. Valves have a much higher failure rate when used properly.

I work at a chemical manufacturing site. Do you have any idea how many millions of pounds of material are lost each year do to a manual valve that was not fully shut.

I am sorry babby, I guess when I got hit in the groin last week playing basketball, it must have opened the valve!


I closed it, I guess it didn't close all of the way!

Yeah, not so sure this is a good idea!

I will tell you want he should do next!

1) Make a list of exactly what it takes to make a clock like this
2) Talk to his friends, who talk to their friends, etc. and spread the list
3) Have as many of the high school students show up at a location on a Saturday and all build clocks
4) Have all of these students show up at school on Monday with their clocks
5) Have all the kids en-mass show their teachers the clocks they made right as school is starting. Make sure they all know, it is a clock.
6) Wait for the administration and police to react.

Problem solved. they can't suspend that many kids at once. The Police can't handle that many kids at once. If they don't respond the exact same way as they did to the first clock, then the lawsuits will fly! They can't respond to that many clocks being brought to school in the same manner so the police and school then have to say, yeah, it isn't that big a deal or they have to let their true crazy shine!

I think you maybe even get as many of the parents as you can to show up at school drop off with clocks as well!

I can only tell you what my friend told me he was told and then I heard it from someone else that worked with the hiring process. When he left his previous company, there were some issues with the hand off and sponsorship associated with our HR getting the sponsorship on the books.

It came down to the point where we didn't think we were going to be able to get it transferred and our company contacted the employer he was leaving and asked if they could keep him as their employer and we would contract his services until it was all taken care of. He was under the impression that he was going to have to leave the country and head back to India.

Maybe he sensationalized things, or maybe the company rep did, but that is the impression he had that he was preparing to leave the country.

I am glad that your experience on the H1-B Visa program has been a trivial task for you. That is not always the case though.

At a previous company, we had an H1-B visa employee that we hired from another company and despite the fact he was sponsored by the other company and we were willing to sponsor him, he almost got deported because of the process of handing off from 1 company to another did not go smoothly.

He worked for us for 3 years, and then went to another job and again, almost ended up deported. It was a nightmare on both ends.

I also know a few H1-B visa employees at my current place of employee who have had similiar fears.

Citizen loses a job or goes to another job, nothing happens. H1-B Visa person always has the possibility of being kicked out of the country if HR screws up the sponsorship.

I am not part of the IT tech industry, but chemical manufacturing and the people I know have been electrical or chemical engineers and not working for Google or other big names like those you mention. So while ti can be smooth, you are 1 HR screw up away from losing your status and being deported.

I am glad you have worked for companies who have it down well enough that their HR has worked for you, but that is by no means the norm for smaller companies.

I agree with what you said. I always try and do my best for my current employer as well. Someone else in the thread said, your stuff should be documented as part of your job. When you get to the point of leaving, you should not be starting the documentation, just have to be organizing it for the next guy. Maybe a nice book that says where everything is so the next guy can find it.

If it is more then that, you have missed the boat already and your predecessor will be cursing you to for the next 2 years, so you burnt that bridge to the ground!

On a different level, since when is important technical documentation solely stored on the company email server anyway?

You wrote, "Detecting a malfunction in a sensor is hard, really hard."

Actually is is quite simple to do. If you get anything more then the cheapest of sensors, they continually diagnose themselves and report back the diagnosis. There are failures that cause the sensor to freeze up and stop reporting. If it keeps sending the same data, easy to detect the value stopped changing. If it stops sending any data at all, easy to see a step change that should not have occurred and you also do a redundant sensors and do 2 out of 3 voting. I could continue with scenarios, but while it takes some work, some program and some costs, detecting a malfunctioning sensors is easy. Cars currently report malfunctioning sensors, most of them with a check engine light.

Not sure of your background, but I am a Controls Engineer. I do this for a living. I am sitting at a plant where I have over 20,000 sensors of various kinds and detecting the fact that a sensor failed is quite easy to automatically detect and alert the operator of failure.

We have satellites in orbit that are visible with the naked eye. The tend to be about the size of a school bus or smaller. School bus is 45 feet long. If you can see a 45 foot satellite as a point of light in the sky, this proposed telescope will be half mile diameter which is 58 times the length of a school bus.

Yes, I do believe this thing would be visible with the naked eye.

You wrote, "people should have a right to not be vaccinated - but they do not have a right to be free from the consequences"

Consequence of you not getting vaccinated because you choose not to is someone else can get sick and possibly die. I would think there is an argument to be made that if you choose not to get vaccinated and then get me sick that you are now responsible for my getting sick. Maybe you should have to pay for my lost work time, my suffering, medical bills and if a death results, then you are responsible to my family for my death.

The exclusion here being people who can't get vaccinated for medical reasons like being allergic to the vaccination. Those few individuals are gaining the benefit of the herd immunity and are put at the most risk by people refusing to vaccinate.

If I knowingly put someone at risk through my negligence, I am criminally liable. Isn't there a case to be made to say that not vaccinating and then participating in society, especially in a big way like working at Disneyland, means you are knowingly putting all of those people at risk? I wonder if some of the people who got sick because of the un-vaccinated workers will sure Disneyland or those workers. I think there may be a case for this...and IANAL, I just play one on web forums.

You and everyone you know are doing it wrong if that is the case. I went to a community college for 2 years and then transferred to a university that has always been one of the top 10 engineering schools in the USA (leave out which one so we don't start a university flame war) and 2 years later left with my Bachelor's in Chemical engineering. My sample size of people I went to class with that did the exact same thing is 10, so that means 100% of the 11 people I knew from school that did community college and did 2 years there and then 2 years a the University did it in 4 years total.

In order to do this, you have to pay attention to the community college, make sure the courses you take the credits will transfer (100% of my CC credits transferred) and then work hard at it. Many student with the same degree as I have from the same school who went there for all of their credits didn't get their degree in 4 years. Many took an extra semester and a few took an extra year.

It is completely possible to get a STEM degree in 4 years and going to a CC first only makes it harder on you if you don't pay attention and research it out BEFORE you choose your CC to ensure you can make it in 4.

What sabri says is so true about the way you answer questions. I have recently been involved in trying to hire a controls engineer and one of the more important things I do is look for someone to say I don't know. I introduce myself at the start of a phone interview and let people know I am a controls engineer and I work on our systems, i.e. I am a technical person, not an HR person who has a list of questions.

Then the interview starts. Every few questions, I hit the candidate with a very technical question. I have a list of about 40 questions that I doubt tere are many people who would know all of the answers off the top of their head. Usually something very specific to our system. I expect the person to not be able to answer the question unless they have very strong experience with the same kind of system as we have. The answer I am looking for is something like:

I haven't worked on that, but I am confident that I could learn how that works.
It has been a long time since working on that. I remember this *insert simple, short explanation*, but know that if I looked it up in this reference text or googled it, it would come back to me.

That would usually lead to a follow up question about something that they learned about to reinforce that they feel they could learn it.

I had several candidates attempt to make up an answer and snow me. A few follow up questions and they usually figure out I know about it and they can't snow me. Usually it is too late though. I will give them a couple of chances with very difficult questions like this, but if they don't figure it out quickly and figure out the be honest piece, no chance I want to hire them.

If they have an advanced degree and apply for the jobs I am looking to fill, they don't even get interviewed because I know we won't be able to meet their salary and/or they will look to leave too quickly and I am looking for longer term candidates. I don't want to hire and train every 2-3 years.

I agree with you. I am a Controls Engineer. Until recently, my controls security was decades behind. Fortunately, Stuxnet happened, our CEO noticed the news stories and started asking questions and took an interest. A small group of controls engineers and an IT person who also did the controls network at the small plants he supports made a team, did research, made recommendations and were given money to start securing our network properly.

We need to start realizing security through obscurity is no security at all and make the changes starting with the vendors all the way through the end users.

A huge problem I have experienced is actually a lack of understanding of security and networking on the part of controls engineers, and a lack of understanding of controls systems by IT staff. I think this is actually one of the biggest problems that creates the security problems. Every place I have worked at or in (did a stint as a contract CE and went many places) there is a stand off between controls and IT. Controls knows what we need to do to make our system work and IT tries to tell us how we have to do things and they don't realize that it is not the same as a buisness network because it will shut the plant down to do some things they would like us to. CEs don't understand enough to secure the networks themselves so we do the best we can and keep IT away from our stuff and muddle through.

We need education on both sides so controls people know what they need to do and IT people who understand the differences between business networks and controls networks. Unfortunately, of all the IT professionals I have worked with, only 2 have understand the controls world enough, or been willing to even listen) to help so we just shut them out. I would much rather work with IT and not have to learn all of this security stuff myself when we have IT professionals who know the security. Granted, they probably don't want to learn about my world the same way I would rather not have to learn theirs, so we are right back at the stand off.

Comment Controls Engineering (Score 1) 158

I am a Controls Department Manager. Controls Engineering is that discipline that programs the Programmable Logic Controllers (PLCs) and Distributed Controls Systems (DCS) that talk to all of the instrumentation in an industrial plants.

Our Operator Interfaces are typically Windows boxes, or vendor specific OS and are tied to a LAN so they can talk to the controls systems. In addition, we are starting to get more and more I/O that is Ethernet I/O (plug in an e-net cable and talk to it that way).

Add to the fact that IT departments at many companies don't get the difference between a business network environment and controls environment and many controls engineers have to learn enough IT to maintain their own network and hardware. At the 3 companies I have worked at in the past 14 years, each company I found few IT personnel who understood what I do enough to help and many more that wanted to do things on my network that would simply just shut down the production lines so I just learn to do it myself with help of those few that understand the production needs.
