-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear Everyone, I was had this pointed out to me, by Simon Perreault <nomis80(a)nomis80.org> (with my reply): "On Saturday 27 Dec 2003 8:49 pm, you wrote: > 1) Please do not cross-post. (This means sending the same message to many > lists.) OK, guilty, but I wanted a varied response, as different people subscribe to different lists. > > 2) Please stay on topic. This has nothing to do with Fedora. Fedora is GNU/Linux, there are C programmers, like you that use Fedora, and it is a general discussion list. What's the problem? I'm not asking for money for for you to join some crazy scheme. This kind of attitude annoys me about GNU/Linux, I am not wasting anyones time, so I don't see what the problem is." And his last reply: "On December 27, 2003 16:11, you wrote: > This kind of attitude annoys me about GNU/Linux, I am not wasting anyones > time, so I don't see what the problem is. Yes, you are wasting time (and bandwidth, as there are some people on very slow connections) when you are not on topic. This list is not even about GNU/Linux, it is about Fedora. General Linux questions do not belong here. This is Fedora-related stuff only. There are tons of Linux and C mailing lists. This is a quick lesson (that everyone must learn, I did too) on netiquette. You should Google a bit on that topic, particularly on stuff related to mailing lists." I am sorry if I have wasted everyones time and bandwidth, but I have spent the last 3 days searching for up to date links and book reviews, some things you never find, like the website: http://www.accu.org/bookreviews/public/ recommended by another user. I admit, I have cross posted, as I not only use Fedora, but Debian, SUSE and Gentoo. These are all different distro's with different user bases. I wanted to get a good feel of what are good texts from all the C programmers out their. I didn't get a response like above from anyone else. Even Alan Cox replied to me. What I don't understand is, and I quote, "This list is not even about GNU/Linux, it is about Fedora." What is Fedora then? Again, sorry to waste everyones time, but you have all helped me out. - -- Regards http://www.magicfx.co.uk http://www.suretecsystems.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (GNU/Linux) iD8DBQE/7f0YgNqd7Kng8UoRAimuAKCikZFb2yBGtrHss8AWHmb7pPwQMwCg4OAT hiT3sr0rPLJBLtQl/uiqQOU= =mTvq -----END PGP SIGNATURE-----

KDevelop. Opinions? Experience?
by Steven T. Hatton 04 Mar '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Has anybody worked with KDevelop? IMO this is one of the most important projects in the Linux Community, and especially in the KDE environment. If you've ever worked with JBuilder, you will know what IDE features can add to the development environment. There is NOTHING comperable for C++ that I know of on Linux. http://www.kdevelop.org/ I like JBuilder, and I like doing business with Borland, so I feel kind of bad holding them up as competition, but JBuilder is mark to meet, IMO.

4 GB address space ?
by William A. Mahaffey III 01 Mar '04

01 Mar '04

I am new to the list. I have various codes currently native on SGI hardware that I am interested in porting to Linux, specifically SuSE. I was attracted to SuSE by the reputed ability to address a larger part of the 4 GB 32-bit address space (larger than the usual 2-GB). To that end, I have tried to port a small benchmarking program to SuSE 8.2, on an Intel P4 box, 2.4 GHz, Biostar P4TSV mbd, w/ 2 GB of RAM (for now) & 1 GB of swap space. This box is a compute node on my network & is accessed by ssh; it has no monitor, kbd, or mouse, & runs in runlevel 3 by default. The benchmarking program executes various floating point array operations on successively longer arrays (allocated w/ malloc) until the malloc calls fail or until an upper size limit is reached. I was running the program last night & observed that I could successfully allocate sloghtly over 2 GB of memory (~2350 MB), but when I began operations, the process (as well as the parent shell & login shell, apparently) hung. I killed the login processes from the machine I was logged in from & was able to log back in w/o rebooting. Several questions: 1. I tried to set up a swap partition of > 1 GB & the installer wouldn't let me, how do I get around that ? 2. Is there a problem w/ having more RAM than swap ? (I have 2 GB RAM, 1 GB swap at the moment) 3. I had problems w/ the installer w/ 2 GB of RAM installed, when I removed 1 GB to test why I was having problems, everything went well, total install in about 20 minutes on newly formatted system disc. Is there a known problem w/ the installer w/ more than 1 GB of RAM installed ?

C++:Can one constructor call another from the same object?
by Steven T. Hatton 01 Mar '04

01 Mar '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 In Java it's quite common to call one constructor from another one in the same objects. Can that be done in C++? Is the same kind of situation handled in C++ with default values for arguments to the constructor rather than having two different constructors?
