Ah, Bach ...
If you want to "pimp it up" a bit, I'd suggest Wendy Carlos "Switched on Bach". There seems to be a terrible YouTube video labeled "Switched on Bach (midi)", which should be avoided. Instead try the sample here: Switched-On Bach - Wikipedia

Gotos are frowned on. You should not use gotos. Long live gotos.
Until someone comes up with a better/faster/concise way of expressing the following DFA state machine (presented in part) I will continue to defend the use of gotos, even if their use cases have gotten significantly more narrow as progress has marched on.
When you need them, there is no better tool.

Most developers know goto statements are "bad" but very few know why or have even read Dijkstra's letter in CACM. And I'm willing to bet most developers haven't heard of the ACM. 
goto statements that target entry into a block (as you could do in older versions of Fortran and Basic) are frowned upon because they make automated program verification impossible - aka "I can't say with certainty how you got here". Well behaved goto statements are not only fine, you couldn't write code without them.
To make it harder for novice programmers to misuse the goto statement, many languages such as C, C++, Java and C# (and many others) have created statements that implement well behaved goto's. They are:break - goto the end of a switch or terminate the closest enclosing iteration statement
continue - start a new iteration of the closest enclosing iteration statement
return - exit the function in which it appears and return to the caller
And most (I suspect all) modern compilers won't allow specifying the target of a goto into another block. So use goto's, but use them the way nature intended.

Not exactly sure what you mean here, but C/C++ certainly allows you to goto into a contained block, or to a label in another code block within the same containing block e.g.
void f(int n)
{
if(n > 1)
goto foo;
if( ... )
{
if ( ... )
goto foo; }
if( ... )
{
foo:
}
} Will compile just fine. You can get a warnings if you have an initialization before label foo, with the right warning options (gcc/clang, at least), but a quick perusal of the warning options doesn't seem to suggest that there's a warning for a goto int a contained block.
But maybe you meant that you can't jump from one block to another, like
void foo()
{
foo_label:
}
void bar()
{
goto foo_label; } But for that you have setjmp/longjmp, which, of course, should be avoided like the plague.

One of my professors was the GOTO person for many of us students, in terms of resolving technical doubts and even giving career advice.
We need more such GOTOs, i feel.

If I were given the responsibility for a state machine implementation like that, I would immediately run to my boss asking for permission to rewrite the whole thing as a table driven machine.
There is no way, with code like that, that I could guarantee that all inputs/events are properly handled in all cases (or given the proper error treatment). I would have to make a huge effort if I were to report a complete set of normal (non-error) ways to go from a given state to another, and which inputs/events would lead to which error states.
I've never written any CP article, but code like this makes my fingers itch to compose an article about proper table driven state machine implementation! Maybe I some day get around to do it

Fair enough. I generated that code using Visual FA. It's slightly faster than the table driven variety, which Visual FA can also generate.

Thanks Chris, it was my mothers funeral, everything went well, the weather was perfect, and I'm sure she would have appreciated all the kind words said by the four speakers. I concluded with some lines from an old poem:
Quote: Farewell to thee, farewell to thee
Thou charming one who dwells in shaded bowers
One fond embrace ere I depart
Until we meet again.

The introduction to The Lounge says:
Quote: The Lounge is rated Safe For Work. If you're about to post something inappropriate for a shared office environment, then don't post it. No ads, no abuse, and no programming questions. Trolling, (political, climate, religious or whatever) will result in your account being removed.
I am focused on the sentence: Trolling, (political, climate, religious or whatever) will result in your account being removed.
However, is bashing and trolling M$, Apple, Google, Meta, etc. when they, as companies, act stupid with their technology/programming/API offerings, OK?
Of course it is 
|

It's not bashing. It's discussing, in painful detail, the issues that we face using our tools as part of a thoughtful dialogue.
To be honest, the state of software today is doing my head in.
(and it's been a while - how are you?)
