Lisp news from Rainer Joswig

Very interesting. Unfortunately still no RSS feed, but I found quite a bit on it that wasn't on Planet Lisp or my other Lisp sources. For example, the fact that Loom is now open source (back then I had to put in considerable effort to get a license - though it was free). When I read through all this Lisp stuff, I'm really itching to do more with it. I just have no idea where I'm going to find the time...

Update: a friendly spirit dropped a link to the RSS feed in the comments

OpenMCL-McCLIM-beagle-backend.jpg

Very cool! OpenMCL apparently will soon have a CLIM based on Cocoa — a prototype is already in CVS. Now if only the tools from Genera were ported to OpenMCL and I wouldn't need to turn on my Symbolics anymore

lispmeister: Assembler Guru: Randall Hyde

Yep - assembler knowledge is very useful. You can only understand certain optimization approaches if you know how the machine works internally. And understand why something is slower than perhaps expected at the abstract high-level language level. My first seriously used language was Z80 assembler and I absolutely don't consider that a waste. And yes, I love the disassemble function in Common Lisp and get annoyed every time again when other interactive environments don't offer something like that. Because with it you can very well check what the compiler actually created from the code - and with basic knowledge of the assembler used, you can definitely guide optimizations for time-critical routines. disassemble is like the scientist's microscope.

Factor Example Server

Chris Double has set up a Factor server that anyone can play around with. Factor is interesting because it has a development environment completely built on web browsers with inspectors, browsers, and editors - so you can change everything via a web browser, including the running code of the server. However, it's not like Zope - so a CMS interface. Instead, they are rather Smalltalk-oriented tools, that is, low-level programming tools. Very nice overall. The language also strikes a chord with me: a mixture of Joy, Lisp, and Forth. Given my affinity for Lisp and Forth, it's clear that I have to engage with something like this.

I/O on Symbian Nokia Mobile Phones

Chris Double has also implemented IO for Nokia phones running Symbian. The whole thing is currently functional on the 7610. Very interesting — IO is a language that draws heavily from Smalltalk, NewtonScript, Lisp, Self, and other languages, borrowing interesting ideas from everywhere. It's a language with prototype-based object orientation and various ideas from functional programming. The language is quite interesting even without a mobile phone.

GOO

Goo is also a very interesting Lisp dialect. Strongly influenced by Dylan and with a very compact syntax. However, the stuff doesn't compile on Jaguar - has anyone managed to get it working and have a few patches ready? I didn't find anything on the web.

newLisp: A better Lisp/Scheme Fusion...

Noted, I need to take a closer look at that. I've been pondering for quite a while what I should move on to after Python - Scheme would be an alternative, but after my longer time with Python, it somehow feels too verbose to me.

Somehow a not entirely unimportant factor that the Lisp community likes to ignore: names shouldn't be too long, otherwise you'll wear out your fingers typing. Sure, with macros you can make things more compact, but that's not what macros are for. A language with a script orientation should help you formulate your program quickly. In scsh, for example, that's far from the case.

However, when I look at the language definition, the whole thing is a bit strange. Many areas feel somewhat unfinished and un-lispy. Some of the concepts (e.g., exception handling) are rather primitive. Also, the foundation on heavily side-effect-oriented programming (due to symbols being used as hooks for everything and anything) is inelegant. And last but not least, the death blow: dynamic scoping. While cushioned by lexical namespace assignments, still: dynamic scoping is almost always more reason for trouble than joy.

Other aspects, however, are quite appealing, especially the very lean language scope and the few but efficient basic data types.

The syntax should become somewhat more logical - for example, marking all destructive functions with !, marking all property checks with ? - that's compact to write and easy to remember. For instance, the choice of set-nth for the non-destructive and nth-set for the destructive variant of changing the nth element of a data structure isn't really memorable and begs for confusion.

All in all, a clever idea, but probably less of a grand slam than it's made out to be. More in the class of Emacs Lisp - script Lisp, but a bit hacky.

Weaknesses in the MIME Standard

Oh Kinners, those Heise guys don't really know much either. Yes, the standard doesn't define every impossible case. So what? RFCs never do either. It's not necessary either - just because a standard doesn't define every possible situation down to the last detail, that doesn't mean programmers can throw their brains away and just build in whatever causes trouble. It's not the standard that's defective or has weaknesses - it's the implementations in the programs. A standard might not be complete - but that would mean that functionality in relation to the content of the standard is not sufficiently defined. But not that everything that's not part of the standard is not sufficiently defined. Or something like that.

2 GB Data Uploaded

Pretty funny. Today my blog reached the limit of 2 GB of data uploads. So through all the changes, new posts, images, etc., I've uploaded a total of 2 GB of data to the server since my blog's existence. Since the Python Community Server had a life counter for uploaded bytes, I wasn't allowed to participate for a while until I patched the Community Server accordingly.

HyperPAD - Application Development Software published by Brightbill-Roberts and IQ Technologies.

While browsing through old software and investigating what became of it, I came across the now free — as in free beer — availability of HyperPad. HyperPad was a programming environment for DOS computers that was heavily inspired by HyperCard. No graphics, but a pretty good recreation of what made HyperCard special — and an almost identical copy of the programming language. Quite amusing for the time, when integrated development environments with GUI builders were still utopias from the workstation market.

Smalltalk/X - the forgotten Smalltalk

Forgotten because I never think about it being there. Yet it is one of the more interesting implementations: free as in free beer, even for commercial purposes. Support costs money (which is fine). Good portability - unfortunately not available on OS/X - when you consider Windows and various Unix systems. And a compiler that generates natively executable programs directly - especially practical for classical application development. Due to the nature of compilation (via a C compiler), integration of external C libraries is also good. So if you can live with the platform limitation, it is certainly a very interesting implementation.
