"Those who can't do, teach."

"Those who can't do, teach. Those who can't teach, teach gym".

Those that can, do
Those that can't, teach
And those that can't teach teach teachers.

Those who can, do.
Those who can't, teach.
Those who can't teach, administrate.

Those who can, do
Those who can't, teach
Those who can't teach, write about those that do and teach.

Those who can't do, teach.
Those who can't teach, manage.
Those who can't manage, consult.

If you can't work, then teach.
If you can't teach, then administrate.
If you can't administrate, then legislate.
If you can't legislate, then litigate.

In Japan, it goes like this:

Those who can, do.

Those who can't, teach.

Those who can't teach, teach EFL. (English Foreign Language)

Those that can, do...
those that can do better teach...
those that can't do either one, criticize.

-- we now interrupt your entertainment programme with an unnecessary opinion which you don't even care sh!t about

This one is especially interesting as it applies to all of us - we call Justin Bieber and Twilight gay... wait, not a good example, we say (insert Singaporean artist name) is lousy even though we can't sing/compose/act/draw, but we still retain the right to say who in our opinion sucks and who doesn't. It is freedom of choice.
On one hand though, the reason we retain the right is because we are the bosses paying their salary; Bill Gates doesn't care about your whining because he pwnzored your @ss.

The reason Justin Bieber and Twilight do not make an example is because it is easy for anyone to be less gay than them, I think it would be harder to be more g@y than to be less.

Online guides and why I hate them

I read that not being precise in the wording of the title helps to dramatize things. By being inaccurate - that is the essence dramatization.

I do not hate all guides - I got a whole tonne of knowledge from the internet. Of course, I process these data and come out with new ones of my own, which I write about and share.

The guides I hate, fall into one or both of the following categories - guides that are written based on second-hand knowledge, and guides that are written by noobs.

You'll be surprised, after reading this post, that if you look around the web you can find a huge number of guides that belong to these two categories.

First, guides that are based on second-hand knowledge.

What are second-hand, or secondary knowledge/info/sources? Those are information that you get from somewhere else, as opposed to info that you get or confirm on your own, which is called first-hand knowledge.

What is wrong with second-hand knowledge? Information dilution and accuracy issues.

You got your info from somewhere. At best you can only repeat 100% of whatever information that is written if you didn't add any of your own. Chances are, you don't get the full 100%.

So if your guide is only going to be less informative and more inaccurate than wherever you got it from, why bother wasting bandwidth and the time of poor suckers who were lured into reading it because they needed genuine help on the topic while you spammed your "guide" on forums as if they are your personal webpages? Just link them to a proper guide instead of taking credit! Oh yes, credit, you didn't get the info on your own so credit where necessary.

Next, guides that are written by noobs.

Recall the definition of newbies - those new in a certain area, and noobs, those that plain suck and think they are pro and hence refuse to learn.
Newbies will never write a guide because they do not think they are good enough. If they think they are good enough but are actually not, they are noobs. Hence noob guides are all written by... erm... noobs.

No need much explanation for this - the guide just sucks.

There is a saying however, that game guides are written by people who get pwned so much that instead of enjoying the game by laughing evilly killing others they find more joy in sharing their unconfirmed theories (read - secondary knowledge) on how to play well. This goes in line with the saying - "Those who can't do, teach".

I'm not against more basic, less detailed guides, because there is always a need for teachers. And having taught before I understand first-hand that you need to teach at the level of the student. For example, getting the guy doing your university mathematics tutorials to teach primary school is impossible. Not that he/she does a good job teaching 20-year-olds either, but you get the idea.

But guides that are WRONG because the author is a noob just pisses me off.

So as you might have realized by now, noob and second-hand guides often overlap.

Oh yes I found a good forum thread on "Those who can't do, teach". I'll extract out the various versions of the saying.

Sighing sighs away happiness

...or so that is this saying. But you only sigh when you're not happy.

Correlation does not mean causality.

No two snowflakes are the same

...But what about two snowflakes with 95% similarity?

Learning while helping others

That's what is called 教学相长.

I learned today that OPA2228 isn't stable at gains of <5.

So why the f are people recommending them in unity-gain buffer circuits?

Before sensors were installed...

Before temperature sensors were installed, electronics ran at 80 to 100 degree Celsius,

After temperature sensors were installed, people cry when their CPU reach 50.

Before fan speed RPM sensors were installed, fans ran at up to 6000rpm in applications where required,

After fan speed RPM sensors were installed, people whine when they see anything above 2000rpm, even though it may be a 40mm fan which he can't hear shyt over his RAID array.

Customer is always right? Nah.
