So to have the coldest coffee: Add milk late, and vice-versa.
It assumes that the milk is _colder_ than the coffee!
It's not a caffe-latte for instance, where this assumption would not necessarily be true.
No, that was called the coffee problem in differential equations. Let the coffee cool first before putting in the milk. The coffee will cool down faster when the temperature difference to the rest of the environment is greater. Then add the milk.
If you want to know if someone is an engineer ask how there last project went, what was good and what problems did they have.
This is a very fair question for the candidate as they should be an expert in their last project and you won’t get false negatives with good engineers who just happen to have a blind spot on your special question.
If you want to know if they are a good engineer then ask what problems other people on your project had and were they able to help them.
Notice the questions do not use the word technical problems allowing someone to start talking about non-technical issues which may be where their comfort zone is.
In theory someone could fake it by talking about the experiences of an engineer they knew. In practice if they are a real engineer there response should start an interesting conversation.
I once interview someone who in response to these questions got into a rage about how other people on his project would not listen to him and they were doing it a wrong. He was clearly an engineer but not one I wanted to work with.
The test for the new manage is much easier.
Where you get a new manager and a suitable technical problem occurs, go into his office and describe the problem and ask if he has any suggestions.
This is a good question because the problem could be hardware, software or a systems issue and anyone with a technical background should have something to say. If he looks at you with a blank face you’ve got problems.
This discussion no VCC and also the one on anode and cathode brings up something I've dwelled on in the past. Often when one is in school, such terms will be presented but not always explained as to why the word itself is used and what its significance is. This can unfortunately make the study of engineering seem much more mysterious than it really should be. A good engineering education should include the explanation of various words and abbreviations and their origins.
Right... the interviewer has to be intelligent enough to pick out the right person for the position. It's as simple as that. If the interviewer isn't intelligent enough for that, there are other problems within the company.
Anode is the Arrow end. Both begin with A.
The cathode bar is marked as a band or dot on the diode body. So why are electrolytic capacitors marked on the negative lead and tantalum capacitors marked on the positive lead?
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
