Visualize an xy axis: some measure of learning is on the y and time (or trials etc.) is on the x.<br><br></div><div class="gmail_default" style="font-family:comic sans ms,sans-serif;font-size:large;color:rgb(11,83,148)">
So if learning goes slowly, the the curve rises slowly. If learning is fast, then the curve is steep.<br><br></div><div class="gmail_default" style="font-family:comic sans ms,sans-serif;font-size:large;color:rgb(11,83,148)">
I know people think of 'steep' as difficult, but with learning curves it is not so. I dunno how this misconception got out there, but it's very difficult to get rid of, like the 'vaccines cause disease' one.<br>
<br>Please help get rid of this cliche'. I taught Learning for 35 years and this is driving me crazy! It's worse than the misconception of negative reinforcement as punishment.<br><br>bill w<br></div></div><div class="gmail_extra">

</div>Visually-wise, they are very nice to look at. But there are some<br>
long-term problems I can see with Javascript. Like, I need to have<br>
compatible browser, so while I could do some stuff in it _right now_,<br>
I don't really want to find myself in the same department where people<br>
cry for help because their old sci/tech reports cannot be read (AmiPro<br>
for DOS or something even more exotic long long gone) etc.<br>
<br>
Besides, I myself can only stand one C-like language and its name is C.<br>
<br>
Learning curve I can negotiate with. There is always some kind of<br>
tradeoff. For example. trading time spent on learning now for time<br>
spent on rewriting from scratch *and* learning something else,<br>
later. The only fancy thing about it is that people AFAICT don't<br>
recognise such situations until someone has to pay for what was in<br>
small print on that last page.<br>

</div>Oh, I could have told you this fifteen years ago, it's just the rest<br>
of the world started to pay attention. And I have really followed my<br>
own advice, i.e. pulled out of Java world, a bit painfully but without<br>
much hesitation.<br>
<br>
Well, ok, I could have told you this ten years ago. Fifteen years ago<br>
I was only sick of Java.<br>
<br>
JVM (i.e. a virtual machine) is something good, however. At least in<br>
some aspects. There really is a need for cross-[operating<br>
system/hardware] environment for code execution. And maybe JVM is a<br>
poor choice but still worthy. Mono is interesting, too. Chances are,<br>
stuff written in Java might be executed in Mono twenty years from now,<br>
or twenty years after Java is gone from desktops (unless some DRM<br>
stuff forbids it). There are some other choices but they don't belong<br>
to this forum.<br>
<br>
Uhm, yep I know, too long, too offtopic.<br>
