Game programming
by rsobba＠kcnet.com 29 Nov '04

29 Nov '04

I am not a gamer but an on again off again home OOP programmer. I need something to keep my interest up while I am learning. Have any of you done any game programming? I am wanting to program in C++ and Open GL but am curious about the graphics end of it. Will I need to create images using a package like Adobe Illustrator first or is this all done somehow within Open GL. Thanks in advance. Rick

RE: Game programming

Game programming is best done in straight C++ with occasional/frequent inline assembly thrown in. OOP programming adds a great deal of overhead to programming in general. But then with the powerful systems in use today, I suppose it is "ok" to use OOP to write games (although I wouldn't). Perhaps that is why so many of today's games require high-end systems, or maybe not. You're going to need/want some graphics/data files. There are a number of tools and probably some graphics you can download, but in the end you're going to need to make some files of your own. I don't do anything with OpenGL or game writing, although I have written and designed a few games. So I may not be the best source of information. There are certainly some objects you can create directly from inside OpenGL (triangles, boxes, pyramids, complex combinations of the same, etc). Go here and take the tutorial. It should also answer your questions better than me. http://nehe.gamedev.net/ > -----Original Message----- > From: rsobba > > > I am not a gamer but an on again off again home OOP programmer.

Re: screen scrollback
by Brian Kelsay 29 Nov '04

29 Nov '04

In Putty, you set the number of lines of scrollback in the Configuration window that appears when you launch the program. You can turn it down to zero or crank it up. XTerm and rxvt, et al have similar features from their options/config menu. screen -h (num) ---- Specifies the history scrollback buffer to be num lines high. also, you can permanently set this via the following: When screen is invoked, it executes initialization commands from the files "/usr/local/etc/screenrc" and ".screenrc" in the user's home directory. These are the "programmer's defaults" that can be overridden in the following ways: for the global screenrc file screen searches for the environment variable $SYSSCREENRC (this override feature may be disabled at compile-time). The user specific screenrc file is searched in $SCREENRC, then $HOME/.screenrc. The command line option -c takes precedence over the above user screenrc files. Commands in these files are used to set options, bind functions to keys, and to automatically establish one or more windows at the begin- ning of your screen session. Commands are listed one per line, with empty lines being ignored. A command's arguments are separated by tabs or spaces, and may be surrounded by single or double quotes. A `#' turns the rest of the line into a comment, except in quotes. Unintel- ligible lines are warned about and ignored. Commands may contain ref- erences to environment variables. The syntax is the shell-like "$VAR " or "${VAR}". Note that this causes incompatibility with previous screen versions, as now the '$'-character has to be protected with '\' if no variable substitution shall be performed. A string in single-quotes is also protected from variable substitution. Two configuration files are shipped as examples with your screen dis- tribution: "etc/screenrc" and "etc/etcscreenrc". They contain a number of useful examples for various commands. http://www.hmug.org/man/1/screen.html Brian Kelsay >>> "Jonathan Hutchins" <> 11/27/04 11:35PM >>> Regarding some recent discussion of getting a convenient scrollback buffer working with screen in an Xterm: I notice that Ctrl-PgUp works fine in Putty under windows.

Apache 2.x and mod_rewrite
by Dustin Decker 28 Nov '04

28 Nov '04

Howdy All, I have a quick question on Apache 2.x (2.0.51 to be precise) and mod_rewrite. I've been trolling documentation at apache.org, but their examples are flying over my head. For the purposes of example, let's say I have purchased two domains - foo.com and foo.org. What I want to occur (without leaning on an http-equiv redirect in the browser), is to have anyone who visits www.foo.com <http://www.foo.com/> automagically redirected to www.foo.org <http://www.foo.org/> . Can anyone share with me a recipe for this that I can chew on. (Or even better, considering how lazy I am, just throw up and live with!) Thanks, Dustin Decker

Firefox taking off!
by Brian Densmore 23 Nov '04

23 Nov '04

"OneStat.com, an Amsterdam, Netherlands-based provider of Web traffic measurement services, said that according to numbers gleaned from 2 million Web surfers around the world, the Mozilla Foundation's new Firefox releases appear to be cutting into Microsoft's still commanding lead in the browser market. "It seems that people are switching from Microsoft's Internet Explorer to Mozilla's new Firefox browser," Niels Brinkman, OneStat.com co-founder, said in a statement. OneStat's statistics, based on the Web surfers' activity in 100 countries, showed that IE's market share slipped to 88.9 percent in the third week of November, down 5 percentage points from its share in May. Mozilla-based browsers, including Firefox, rose to 7.4 percent, up 5 percentage points from May." Mozilla based browsers with 7.4% of the browser market? Wow, I'll bet Firefox is in M$'s scopes now. I wonder how long before the FUD begins? I'm not sure FUD is going to help them here. I bet they'll be "buying" up one of the third party IE add-on/resellers to get up to speed with Firefox. A new browser war on the horizon? Now would be the time for Mozilla people to approach PC vendors to get Firefox installed on new PCs. Brian Densmore

OT: Windows Boot Disk
by djgoku 23 Nov '04

23 Nov '04

I'm trying to configure a DOS floppy boot disk (bootdisk.com) with out a ram drive for ghost, and for some reason it isn't detecting the hard drives, just loads the floppy and cdrom support nothing else. My reasoning for this when I boot the disk that does a ram drive in the ghost save menu there is like ram a drive, both cdroms, 3 partitions, and a couple other things that I don't want in there. I do have a boot cd that I'm trying to emulate it which doesn't have a ram drive or lots of drives in the ghost save menu. I'm not totally sure which file autoexec.bat or config.sys loads/searchs for hard drives. Thanks, -- dj_goku -www.djgoku.com- -www.tektronic.org-

Searching for hds, in dos? That doesn't happen in the autoexec.bat or config.sys, unless it is some strange hd. It happens inside the dos boot programs io.sys or msdos.sys. Loading RAM drives is a different story. To load a RAM drive in DOS it needs to be loaded in the config.sys file, something like this: DEVICE=path\to\RAMDRIVE.SYS size sector entries [/E|/A] HTH, Brian > -----Original Message----- > From: djgoku > > I'm trying to configure a DOS floppy boot disk (bootdisk.com) with out > a ram drive for ghost, and for some reason it isn't detecting the > hard drives, just loads the floppy and cdrom support nothing else.

I think this was meant for the list. I should have clarified my statements. I was referring only to the GUI package managers, as was the gist of what Jonathan was saying, I think. > -----Original Message----- > From: Dave Hull > > Quoting Brian Densmore <DensmoreB(a)ctbsonline.com>: > > > I can attest to this.

PDF pseudo-printing (Debian CUPS)
by Monty J. Harder 23 Nov '04

23 Nov '04

I must be really dense. When I look at the Control Center - Printers in KDE, I see printers listed that include printing PDF to file, but when I try to print something out of, say, Firefox, they don't show up in the list of printers. When I connect to localhost:631 and try to add a printer, I don't see any option to add a printer as print-to-file. What am I missing?
