Submission + - Tcl/Tk 8.5 released ( 2

wordtech writes: "The Tcl Core Team is pleased to announce the 8.5.0 releases of the Tcl dynamic language and the Tk GUI toolkit. This is the first stable release of Tcl/Tk 8.5, following more than four years of development, and represents a major advance over previous versions of Tcl/Tk.

Highlights of Tcl 8.5: * Speed: 8.5 now runs 10% faster than 8.4 with bytecode improvements, object caching and reduced memory usage. * Bignums: Tcl now supports arbitrary-precision integers, which improves math operations on large integers. * Safer interps: Tcl's powerful safe interpreter mechanism now has improved control of time and command limits in slave interpreters. * clock command: More robust implementation of command for specifying time, with significant l10n and i18n improvements. * dict command: New data structure that allows access to data by value rather than a variable name, which is substantially faster. * Additional improvements: Faster list search, new and improved mathematics procedures, anonymous procedures, new ways to package Tcl extensions, Tcl-level custom channel types, file and line location information for each command, and more.

Highlights of Tk 8.5: * New modern theming engine: New and additional widgets that make use of platform-specific theming on Mac OS X and Windows to better fit in with those environments, and feature an improved look and feel under X11. (For screenshots, see * Font rendering: Now uses anti-aliased text under X11, and a more modern text engine (ATSUI) on Mac OS X. * Text widget: Smooth scrolling, widget peering, and improved procedures for counting and replacing text. * Additional improvements: Window transparency, new fullscreen option for windows, enhancements to specific widgets and window layout, and more.

Submission + - Programming Language Popularity Statistics (

DavidNWelton writes: "I redid some statistics I did a few years ago on programming language popularity. It's not scientific, nor terribly accurate, given that it's simply not possible to know these things at any level of detail, but I do think the results are broadly relevant. Not that you should choose a language based on popularity alone, but it's fun to look at."
