- Is software a form of applied mathematics?
- Last week's licensing discussions sprouted an interesting, if off topic, thread on a number of computer language related issues. One of the issues raised strikes me as fairly fundamental: is software a form of applied mathematics?Here's how occasional contributor b3timmons stated one side of this argument in response to...

- Guy Steele's new programming language
- Guy Steele's new programming languageEver heard of APL?Great for formulas.You can write in ASCIIAccording to the manual you can use ASCII keywords for all the special symbols. So if you were just using a text editor you would write it kind of like a conventional program. But if you used...

- APL, COBOL,
- APL, COBOL,GOTO "hell"APL is another example of too much rope. Something that is infinitely configurable is infinitely breakable! The ability to write an entire program on one line makes for some VERY hard to read programs. And I DO wonder about the security implications - would code audits become unmanageable?...

- APL, COBOL, & Dijkstra
- One of the issues that arose in the talkbacks to my blog on the Second IT Commandment (Thou Shalt Honor and Empower thy Unix Sysadmins) came from a throwaway comment, on my part, about the difficulty of teaching a COBOL programmer to use APL. That drew a response from Jorwell...

- Resurrection Time?
- Sun has a large group led by Guy Steele working on a language called "Fortress" -something they describe as "Java for scientists, Java for the programmers of a peta-scale supercomputer." Java started out as a hardware abstraction layer for set top TV boxes aimed at using the TV to provide...

- APL, Parallelism, 44.8 < 3.6
- APL, Parallelism, 44.8 < 3.6well..I think the massive increase in parallelism in the processors would be best utilized if a user/the system would dedicate certain cpus to certain task/process/service/threads. In an unix environment dedicating one processor to run Apache, another to handle mysql, i know it could get messy...

- APL and parallelism
- Quite a number of otherwise respectable people seem to be believe that Sun's throughput computing initiative will never produce a CPU appropriate to workstation or laptop uses. Their basic argument is that the first generation Niagara CPUs are weak on floating point and that all of them trade off relatively...

- N-Tier: Rube Goldberg meets Wintel Scalability
- The core claim made by N-tier architecture proponents is that this structure breaks an application into modular elements that can be separately maintained and used for more than one application. In the simplest possible version of this you have at least one database server, at least one...

Unfortunately almost nobody in the press understood either the announcement itself or where Sun's taking this, with the straight up treatment given...
