There's a bit of a furore here about the publisher "re-wording" much/most of Roald Dahl's childrens' books, to remove "offensive or discriminatory" language. On a morning TV news discussion today, a supporter of the move said "But the essence of the story remains the same". Sadly, "the essence" is not what makes a great book. The "essence" of Willy Wonka's chocolate factory is that boy from deprived background wins ticket to chocolate factory, has a great time. "He was an enormously fat boy" is not equivalent in meaning to "He was enormous".

These "essences" do not do justice to their originals. "Essence" is not what makes great writing. If the words and attitudes expressed cause offence, then take that as learning about the past; if you don't like it, don't read it.

One of the participants this morning was complaining about the James Bond novels, which I think most of us would agree include some rather racist and sexist views and language. She was up in arms about it, how it would affect younger readers and present these as acceptable attitudes. Then she shot herself in the foot by saying her teenage daughters read one of the books, and were falling about in hysterical laughter at the attitudes presented. They knew it described views that no-one can take seriously these days, and certainly didn't feel "objectified" by the words.

[Sorry, gone a bit off-topic here, but it did annoy me. Apparently the Roald Dahl publishers have now agreed to continue publishing the original version, along with an edited "PC" edition.]

The "essence" is the action. What happens, what this and that person (or whatever) is doing. Any "idea", any thought (beyond the level of "good vs. evil", which is anyway reflected in the actions) is inessential.

(An aside: Was your post really meant as a follow up to Mircea Neacsu's post? I do not see the connection. Did you intend it for another thread?)

Yes, I was going a little off-topic, but reacting to "Now even writing as a whole take a step backwards". There's a difference between being "politically correct" and dumbing down writing to the point that whilst it may still describe the action (as you put it) it does so blandly and without personality. It's depressing when even publishers don't seem to "get" that deleting words from a text also deletes not only a lot of meaning but a lot of the pleasure too.

Quality of documentation went down the drain some time ago

Could you put a date on that?

I know in the 90s that I only ever found one library that had good documentation.
In the 80's I learned C++ using exactly 3 books. One was the Stroustrup which was a specification. Other was not even C++ but rather Object C (or whatever it was called). Third was by a woman (very rare then) and it seemed rather effective.
In the 70's the only thing that existed for Fortran and Pascal were the functional reference manuals. And really expensive. I think I got one of those by pulling an old version out of the trash.

I've used the ARM (Annotated Reference Manual) by Stroustoup and Ellis. Btw, if the woman you are talking about is Margret Ellis, she is very effective author.

The number of manuals was smaller but their quality was much better (me thinks). That depends also on the style of documentation you like. Me, I'm a fan of dry, terse and complete manuals.

However the 90s was when libraries for C/C++ started to become available. But Stroustrup was documenting the language and nothing else. And the Ellis book (80s) did the same but more on using it rather than what it was.

So as I already mentioned in the 90s of the many libraries I used I found only one that had good documentation. There were more good books published in the 90s (Meyers and Ellis) but those were still on using C++. So they expanded what what already there but the additional stuff was not documented.

I find learning new languages extremely boring because it's just variations on a theme. (No amount of coffee) On the other hand, researching a new problem domain can send me happily in all kinds of directions for months even if it isn't any easier.

But that of course is how it works. The evangelists either do not know or do not want to tell about the problems that those 'new' technologies will introduce.

Of course but not sure if that fits into 'new' technologies.

Very, very few. Hype does not equal use. And definitely does not equate to wide spread use.

I had been struggling with my render code for days until things went from bad to worse and I was getting artifacts due to corrupt DMA transfers on top of drawing code errors and other messes.

Finally I sat down and rewrote the damned thing. Not only did I do that, I made it so I'm sending with one buffer while drawing to another buffer, then flipping them to maximize the benefit of DMA.

Not only that, it's now basically a coroutine.

All of this and my render code is actually simpler than before, and it appears to work swimmingly so far.

Took me several hours vs. several days.

All the win. Now I just need to implement touch.

Edit: Got touch working. That was easier than I thought it would be. Woo!
