There is a difference between acknowledging hatred and carrying it.

Or perhaps kids just forget more quickly.
Also, I'm going to have to disagree - not with that it would change the world, but that it's a skill. Carrying a grudge long past its expiration date is what really takes skill.

Everyone I work with is a House MD, a Doc Martin, an Office-Space-Red-Bostich man. I'm the only sweet person "not nice, just sweet"
That said I wish to emulate the great sales people that come to do demo's and are ever so nice and informative despite a hoard of ill tempered coders and statisticians.

Infinite series summations - used exactly once. At least the use then was amusing.
Never:
Differential equations.
Electrical field theory.
Perfect refrigerators (figured out in the class that I wouldn't need that one.)
Proving why there are only 5 platonic solids
Infinite series multiplications

My favorite of course was "Great Books". Two semesters. Definitely the case where the movie is better. Fortunately there are vast number of movies made from most (or even all far as I know) of the books that were covered.

Funnily enough I wrote a bubble sort only the other day - but only as an explanation to someone how they could sort a high-score table.
Things I learned but have now forgotten are many - due to my advanced age and overuse of stimulants, but they include;
The hex values of every 6502 op-code. When I was writing games on a 6502 platform I often wrote code in a notebook and hand-compiled. It got to the point where I could just type in op-codes.
How to skateboard (although I actually do remember how, I just can't do it any more due to a fear of falling and killing myself)
Delphi
RPG

So far anything math related (aside from the very simple primary school stuff like adding, subtracting etc.).
Sure, it keeps coming back to haunt me. I now need it again for my IT study.
Knowing math certainly gives us more insight into the world, physics, biology, chemistry, computing... The list goes on and on.
But I've never actually needed it myself!
I sort lists every day, I look up records in lists and tables, I do all that mathy stuff, but the math was implemented by others.
Don't ask me to solve for x or to write/think of an algorithm.
I did it all back in school, but can't remember for the life of me...

I surprised myself a while ago when I didn't have a calculator handy and had to divide a five-digit number by a three-digit number and didn't remember how to do it with paper and pencil. Note that I saw my first 4-function electronic calculator ever when I was in last year of high school; I never took a single exam when calculators were accepted as a tool.
Admittedly, after a little fiddling back and forth, and a lot of head scratching, I did succeed in performing the division by hand. Yet it did scare me. I never noticed that I no more could do division with ease.

Calculus; actually, all forms of mathematics above trigonometry, except for matrix algebra which I've used. All of the engineering applications of that math - linear systems and the like.
As far as software subjects go, there've been quite a few things I've learned which I haven't used in a long time. Out of that list, however, I can't think of a single thing which I learned and then never used. The closest candidate would probably be assembly language for PIC microcontrollers, which I learned well enough for a two month-long project a few years ago.

When I started in the industry, there were only six recognised programming languages (ALGOL, Assembler, Basic, Fortran, COBOL and RPG). I learned all six, but RPG was the only language I never used. Nowadays, I can program in 2934 computer languages. (If you know the basic six, you know the rest.)

Using a keypunch machine to punch the format card that you put into the keypunch machine to get good tab stops for columns 6 and 72 for FORTRAN programs, or for whatever.
My problem here is that I can remember how to do it so it's can't count as a 'forgotten skill'.

I have read the book, been sent on a three day course to London, believed the hype, and fed the line. And so did my managers.
I only used it for a year.
After that, it just seemed to die a death.

Nothing, I used everything I learned and the "good" jobs always required a little more to make the job challenging instead of boring.
However, there are skills I haven't had to use in some time, but I'm sure they'd come back quickly.
In fact, there have been some that my arcane knowledge has been a boon. For instance, one company I worked at required a specialized printer to be able to print barcodes using ESC sequences. To everyone else, ESC sequences were total FM (Field Magic is the polite decode of that). So being of the vintage that I used to need to use ESC sequences to print Bold and Italic on my Epson MX-100 14" wide carriage dot-matrix printer, the task was a snap. For years they kept coming back to me to modify the program because no one else at the company had a clue.
Other skills languishing are Assembly coding, spooler writing, communications packages, real time controls, the list is extensive.

Talking at the dinner table or at the pub. Nowadays you can see a load of people sitting in a circle messing with their phones. They just sit together but nobody talks anymore. I've seen a family of 4 go out for a meal. They are messing with their phones before the meal, during the meal and after the meal. They've actually forgotten the skill of verbal communication.

Hi All,
A bit de-mob happy, it sounds like one of our customers is see some odd behaviour. Which would be my thing to sort out but it looks like I'm not going to get to fix it!  (Yayy! it generally involves the scary temperature box)
|
|
|
|
|
Don't forget, if they call you back in to fix a problem you charge the maximum hourly rate (plus tax) for a minimum of 8 hours - even for a ten-minute fix.
- I would love to change the world, but they won’t give me the source code.
|
|
|
|
|
Oh yes, it's a two day issue, have to test it at high temp & low temp & possibly a temperature cycle, have to be certain! 
|
|
|
|
|
Remember, maximum hourly rate ...and I get the usual 10%.

in computers' circuits is the bit 0 really represented by no currency or it is a small signal that the computer is made to treat as 0 ?
thank a lot !

Depends on the chip. Some read -5V as 0 and +5V as 1. Some are tri-state using -5V, 0, and +5V. It's actually voltage and not current that it is using. At least the chips I worked with years ago were that way.
[Edit] And yes, some chips used 0V as 0 and +5 as 1. [/Edit]
There are only 10 types of people in the world, those who understand binary and those who don't.
