The following tweet by @DSpinellis:

#USENIX @AnnualTech M. Renzelmann Decaf: Moving Device Drivers to a Modern Language (Java). He says performance impact is 1%

talks about “Decaf: Moving Device Drivers to a Modern Language” which describes a system where large parts of a driver can be written in a better language than C, the example here being Java.

I was certain that this was not the first time I had read about such an idea. This weekend I was able to go through my archive and find out the reference. Back in January 1997 in the NT Insider (Volume 4, Issue 1) Peter Viscarola, while criticizing the multitude of startups founded by anyone who could code a Java applet (this was a pre-dot-boom era remember) wrote:

It’s obvious that we are missing a real opportunity here to capitalize on the convergence of these trends. We need to immediately fund a start-up company to develop a package for writing Windows NT drivers in Java. THINK of it! We could have processor architecture independent device drivers that don’t even need to be recompiled in order to support X86, PPC, and Alpha machines! Amazing! We could create a visual driver development environment, complete with cute animated assistants. And, the drivers could probably have a visual component to them, so you could actually see your toaster-oven driver doing its work. Cool! THEN we could all be challenged, and have fun, and get rich at the same time. Wow! Why didn’t I think of this before?

It would be nice if we could see Peter’s views on the subject 12 years later.

Clickomania, ο απόλυτος χρονοφάγος. Για χρόνια έπαιζα μια εκδοχή του παιχνιδιού που έτρεχε σαν Java Applet κάπου στο Brown (εάν τη θυμάται κανείς, ας μου στείλει το (πεθαμένο) URL). Όμοια και η εκδοχή του που περιλαμβάνεται στο Axim X3 με έχει συντροφέψει σε πάμπολλες διαδρομές με το λεωφορείο. Ψάχνοντας μετά από καιρό το site του παιχνιδιού, είδα πως έχει και Ελληνική μετάφραση.

Μην το παίξετε. Έχετε προειδοποιηθεί.

The Gosling Tarpit

2009/07/11

I think Panagiotis is going to love this:

“because the Java programming language and Java Virtual Machine are (surprise!) so tightlyCoupled, new language designers are compelled to make their languages such that they use only those features they can implement efficiently on the JVM. For example, implementations of Scheme for the JVM either lack call/cc or have a very slow and slightly buggy implementation of it. We call this the Gosling Tarpit.”

From Phosphorous, The Popular Lisp.

– Στη Java πατάς την τελεία (.) και σου βγαίνουν οι επιλογές. Δεν είναι σαν τη C που πρέπει να τα γράφεις όλα με το χέρι.

Δεν κατακρίνω αυτόν που το είπε. Αυτοί που τον έμαθαν να σκέφτεται έτσι πρέπει να βρούν τρύπα να κρυφτούν.
