> In Oberon, safe and unsafe operations are clearly distinguished. Indeed! To use the unsafe (predefined) procedures you must import the pseudo-module SYSTEM.

I think a device with a camera/microphone should have a physical on/off button and a LED which indicates when it's on. At least, that's how I would design it.

And Modula-3 but not Modula-2, Pascal or Oberon.

I was thinking about the Oberon operating system, which also already exists.

But why throw something away which is not physically broken? I currently use a Mac Mini from 2009 with Debian and I have no complaints... well, except that software keeps getting slower.

Sooner or later you will have to buy a new device due to planned obsolescence, i.e. when (security) updates are no longer released. But then you can of course install a free operating system instead.

You can achieve that using pipes, see https://stackoverflow.com/questions/17071702/c-language-read... . With OBNC you can easily implement an Oberon module in C which interfaces to the POSIX function `pipe'.

What sets Oberon apart is that it has become smaller and simpler over time, something which is not true for the languages you mention.

The Oberon language is an exception, it goes the other direction. https://www.miasap.se/obnc/oberon-report.html

What I miss is a low-resource email client with a GUI, something I (in principle) can run on a 20 year old computer.

Or maybe better: awk '! visited[$0] { print $0; visited[$0] = 1 }'

And here is the ungolfed version: awk '{ if (! visited[$0]) { print $0; visited[$0] = 1 } }'

My suggestion would be: Learn basic POSIX Shell (sh). It's smaller than Bash and more portable. https://pubs.opengroup.org/onlinepubs/007904875/utilities/xc...

If you are implementing a compiler you do what makes most sense for the target language/machine. On the other hand, if you specify exactly how each ill-defined operation should be handled you 1. restrict the freedom of compiler writers

The programmer should make sure that an integer is within the range of a byte before assigning it to a byte variable. It's no more complicated than that.

Oberon-07 is simply the latest version of Oberon, like Python 3 is the latest version of Python. Other non-Wirthian Oberons are best viewed as forks of the original. The result of assigning an integer > 255 to a byte is unspecified; it&#

The designer of Pascal, prof. Niklaus Wirth, evolved the language into Modula-2 and then Oberon. Oberon is a refreshingly lean language. The specification is only 17 A4-pages long: https://www.miasap.se/obnc/oberon-repo

But why change the meaning of one of the most common mathematical symbols? Every new generation of programmers must then relearn what "=" means. If you see "=" in a comment you are never really sure what it means, is it

"Choosing the equal sign to denote assignment is one notoriously bad example that goes back to Fortran in 1957 and has been copied blindly by armies of language designers since. This bad idea overthrows a century-old tradition to let =

Sometimes idiomatic code results in code which is hard to understand, as exemplified by the C idiom `while ( s++ = t++);' for copying a string from t to s. It's always good to be able to read idiomatic code, however.

Or with common mathematical notation: O(2*n) = O(n)

Implementation-wise, with message passing the operation to be performed is sent as a parameter to a message handler. A method call, on the other hand, is simply the invocation of a subroutine stored in a record field (a function pointer).

OBNC is just a compiler. Whereas other languages evolve by adding more and more features, Oberon seem to converge to a set of features which are tried, tested, orthogonal and (most important) essential. Wirth has been very careful not to in

For those interested, Oberon is the current Pascal. It is also designed by Niklaus Wirth. I use the OBNC compiler ( https://www.miasap.se/obnc ).

That's why quite a few languages don't have block comments. But then it gets very tedious to comment out a section of code without a language aware editor. For me, having comments and strings highlighted is essential.

Indeed. Clipart is low culture.

Using a proportional font is also common (recommended) when programming in Bertrand Meyer's Eiffel or Niklaus Wirth's Oberon.

Check out Oberon which is the current Pascal. I use the OBNC compiler ( https://www.miasap.se/obnc ).
