another newbie question
Hi all, Been playing around with FreeBSD for a couple of months. Just configured my .muttrc, and I'm able to send messages but not to receive. I read the man pages and followed the instructions but still it's not working. Am I missing something here? Any help will be greatly appreciated. Thx P.S.

Well, yes. mutt is a mail reader, and that is all it does. It doesn't send mail, it doesn't receive mail, it doesn't even have an editor to call its own. In order to send email, mutt sends its output to sendmail (or your site's MTA). To receive mail, you need to have an SMTP server running. If you want to collect mail from your ISP's server, you will need to configure mutt with your POP or IMAP account details (instructions for both are on the mutt.org website), or use a third party program such as fetchmail to poll the remote server for you and download any waiting messages.

Firefox problem...another newbie question
Been messing with FreeBSD for a week and a half or so now. Getting my laptop all setup to play DVDs and something wierd happened to Firefox (probably unrelated I know). As an aside, xine works well but i'm not a fan of the gui, gxine core dumps a few seconds after going fullscreen or toggling a couple of times. They use the same engine right? Wierd...both installed from recently upgraded ports tree on a gnome 2.12 6.0-beta5 system. The firefox problem... I can replicate this as at will and epiphany works fine. If i click a .tbz file or something that calls another app and i get a core dump.

I need to buy a book on C or C++ to help me in FreeBSD. Which would be better to buy? I first thought a book on C would be best, because the OS is written in C.

Re: Firefox problem...another newbie question
It seems that there is some problem with your glib. You might need to upgrade it. Note that portupgrade isn't working for glib/gtk 2.8.x upgrade. You need to use gnome_upgrade212.sh instead, check /usr/ports/UPDATING for details. cheers, --ken On 10/11/05, makisupa <[EMAIL PROTECTED]> wrote: > > Been messing with FreeBSD for a week and a half or so now.

This doesn't answer your C++ part of the question, but you should have the Kernighan & Ritchie "The C Programming Language" and then get something like "C A Reference Manual" (Latest edition is 5th I think) by Harbison and Steele.After that you might look at "C Programming FAQs" by Steve Summit. > > I first thought a book on C would be best, because the OS is written in C.

Thanks, Jerry. So, it sounds like I should probably tackle C before C++. By the way, I saw the first two books you mentioned in Borders Book Store today while on my lunch break.

I used to teach both C and C++, and now years later, am currently hard pressed to find a non-Microsoft C/C++ development position. If for personal knowledge, definitely C followed by C++. If professional, or want to behmm. In that case, I'd say it still depends more on your goals- if you're going to try to stay in *nix development, you've GOT to know C. If you don't care, or God help you, want a job doing Windows development, start with C++, and ignore all of the standard data types because MS will make their own for you ;-) Starting with C has an advantage in that you tend to have to do 'most of the work yourself' for a lot of things, which tends to help you understand more about how things work. IMHO, that also tends to make better programmers down the line, regardless of the language they use. C++ is similar, but STL will make life easier when it comes to data structures. Java I don't want to talk about ;-) A significant amount of system level programming(think system processes and services/daemons) are written in C. A fair number of applications are, but the majority of GNOME/KDE apps, if that's a consideration, are done in C++. A growing number of applications are also being done in Java, but it's not the best language to start with for understanding much of anything (you can write a half dozen lines of Java to replace perhaps 100+ in C/C++ from scratch in some cases). It isn't a bad language to learn (professional-wise as well, *groan*) after learning C or C++. Books and references- C- Already mentioned, K&R 'The C Programming Language' is 'the bible.' This is also generally a lousy book to start with if you aren't programming already, but an invaluable reference. Pick up another book, wish I knew a good starter one, but it's been a while...can try Deitel and Deitel or (nobody laugh, have used it for Intro before..) the 21 days SAMs series for a 'jump-start,' and THEN the Deitel/Deitel and K&R. W. Richard Stevens "Advanced Programming in the UNIX Environment"- MUST HAVE. I may be misquoting the name, but a search on bookpool.com , bn.com (or search on amazon then BUY somewhere else!) will quickly turn it up. K&R is to the C language, Stevens is to Unix programming... google search for 'Secure Unix Programming'- there's a FAQ or two out there that are pretty good once you're past 'the basics.' C++ Latest edition of Deitel/Deitel. Funny, I used to really dislike their books, but they DO provide pretty decent overall coverage. May or may not be 'too deep' at first, if so, preface with SAMs or equivalent. Stroustrup- 'The C++ Programming Language". Stroustrup write C++ but is pretty dry. Good reference and for advanced topics. Stroustrup- Annoted Reference Manual AKA 'the ARM'- what K&R is to C. *The C++ Standard Library : A Tutorial and Reference- recommended pretty highly, but don't currently have. search on favorite bookstore will turn it up. *Java (before ya ask ;-) There are a LOT of bad books on Java it seems. Deitel and Deitel again is worth buying as a first book (after C and/or C++), then decide what you want to DO with Java, as there are a number of directions- JDBC, Beans, JSP, etc etc etc.. As always, languages and books can be a moving target- when possible, pick up the latest edition covering the current ANSI standard for C/C++, and make sure anything you buy for Java covers 'Java 2,' preferably JDK 1.4, but at least 1.3 or you'll be throwing out work by the time you work on a current project.. Misc others- POSIX Programming, O'Reilly press. Good coverage of POSIX (Unix for simplicity's sake but not really) required system calls. Network Programming- Again,m by Stevens.

Re: Another Newbie Question: C or C++
I need to buy a book on C or C++ to help me in FreeBSD. Which would be better to buy? If you just want to start programming in FreeBSD, Learn C as well as you can. The route I took was learning basic programming skills then reading "The C Programming Language" by K&R, it's an excellent book if you are already very familiar with the computer and have some basic programming skills (make sure you know your c development enviroment and how to use gcc). The book is so great because not only does it teach C syntax, the examples open your mind to writing simple and efficient code in a C style, and it even has a small UNIX programming tutorial toward the end (on how to implement some of the standard library functions in a UNIX system). That book and a good familiarity with the man pages is really all you need to get started coding on FreeBSD. If you are still a little lost and really want to go on the quick route to good BSD programming, read "UNIX Network Programming" by W. Richard Stevens. The original edition introduces you to good fundamental knowledge of the UNIX system and archictecture (process model, system calls, and IPC) then it goes right to socket programming which is a must to know especially in this day and age. The later editions seperate the actual socket programming from the unix stuff but go intensely in depth. That's why i'm fonder of the first edition, concise and smart. I first thought a book on C would be best, because the OS is written in C. But, now I'm not sure because I read that gcc can compile C++ too (so, I'm assuming C++ must get used too). Now that you've had good practice with C and UNIX programming, learning libraries (GTK, QT, pthreads, GD to name a few) is simply a matter of reference and learning any other language else is simply a matter of syntax and style, and everything will come very easy. If you haven't learned C++ by that point just figure out what Object Oriented programming is (it'll beautify your life), get a reference book, look at some coding examples, and no sweat. Java? Perl? Python? Javascript? Visual Basic (haha)? They'll all just be minor changes in syntax and style when in comes to C/C++ (except for python, hah). Hope that helps and good luck! -Rian Hunter _ MSN Messenger with backgrounds, emoticons and more. http://www.msnmessenger-download.com/tracking/cdp_customize ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Agree completely on the C/C++ application/philosophical differences. The book list missed one very useful C++ book by Josutis, "The C++ Standard" I think. Don't have it handy. You know, everyone's been telling me to give up C and just star

Wrong. C++ is based on C, but it has made some changes so it is not
quite a superset of C.
Try for example the following little program:
#include
int main(void)
{
char *a;
a=malloc(10);
if(a) free(a);
return 0;
}
This is valid C, but not valid C++. (C++ does not perform automatic
conversion between void pointers and other pointers.)
This should suffice to demonstrate that C++ is not really a superset of
C. The intersection between C and C++ is a usable programming language
though, but it is rarely worth the trouble to restrict oneself to that
subset of the languages.

Re: Another Newbie Question: C or C++
A decent school will start you with C as an introduction to programming
then teach you basic C++ (you write your own abstract data types).

For a teach-yourself strategy that sounds reasonable.
Just remember that studying from computer books costs time and money too.
IMHO, after all is said and done, the cost is the same, but you will profit more if
you take a class.
Good luck with your efforts!

All I have is the secondhand publishing of several different, and mostly conflicted sets of operating instructions, most of which are even self conflicting. So self taught isn't necessarily right the first time - unless the docs are all forged :) Then again, I could be entirely mistaken about your meaning, so feel free to ignore my babble before flaming (in fact, please do :). Besides, every person is different. Some people need some degree of structure to focus them. Others do better on a 'spur of the moment' schedule, where they spend time learning when it will be productive. I go for a walk down the middle of these perfectly valid, if fundamentalist, approaches. A person who only learns in school never learns outside of school. OTOH, a person who avoids structured learning environments will have a hard time in other structured environments. Most of my C++ knowledge was gained in school. My much more extensive C knowledge was entirely self taught. Yes, I do have the occasional pointer mishap, but I doubt there are many people who don't.

This is a good point. The person who takes a class should (prividing the class is well done) be guided through the whole range of the language. Whereas someone learning on their own just picks up the pieces they need at the moment and then fixates on those parts and doesn't go on to learn the whole range of the language. > If you want to get a lower paying and boring job programming in C/C++ for > whatever reason and have a piece of paper that says you can have that job, I > recommend wasting 4-6 months taking a course in your spare time to learn > C/C++.

If the material was already there in the beginning as it is for C, C++, Fortran, Assembly, etc, then that lifelong process could have started at a higher level of understanding and moved on from their instead of having to spend so many years of rummaging around at the primative levels.

Also be prepared to teach yourself because you may not always be prepared for a job you may find yourself with; learn how to easily learn and use external libraries. Like others it seems, I have a problem with _part_ of this statement. I have taught C++ and others previously, and can say _some_ people respond much better to 'guided' learning in person- eg, classes. Those that take what they leanred in class and go on to actually apply it, or come up with questions on their own and then pursue the answers on their own time, become much better programmers. Others are completely capable of learning outside of a classroom environment- Note I didn't say 'on their own,' because a good book and _working code_ examples, and then their own working code, are all invaluable parts...so anyway, I don't agree with ALL classes being a waste, although it highly depends on the instructor, the student, and perhaps most importantly, what the student DOES with the information given to him. A very good point was brought up though, and it used to be embedded in every class I taught- the things not nescessarily language specific- problem analysis, design, good programming practices and structure. These are not always taught in the 'usual comp programming classes' unfortunately. The other point I used to mention (while teaching Pascal, heh!) was if they took only a single thing away with them from the class, it was this: You MUST learn how to do research on your own, and solve your own problems! That doesn't mean never asking for help, whether in person, via mailing lists or newsgroups, but it means if you have a problem, you should be _capable_, and know how to, research it yourself first. When you think about it, every single program created is unique (k, cept maybe where SCO stole source code and then cried to lawyers about it ;-). Even programs that have the same design, even down to the API level, are unique. When you start a new project, on your own or in a group, it's HIGHLY likely you will be doing something you have never done beforeso learning how to find information you need, quickly, becomes paramount. The best programmers will teach themselves. A statement that may be on the borderline of opinion to fact by constant example.

RE: Another Newbie Question: C or C++
first of all, sorry by my English I am agree with people who says take courseworks, and those who say learn your self, I did both, but first I had to learn on my own, and that´s really a very, very hard task to do! ;) and I only recomend it if you are some kind of Indiana Jones and have time enought to dedicate it . The benefits of self teaching I found, were the goals. The first time I made a pointer works were the hapiest day of my life!!! and the first program I made can you imagine!? :) Another thing to point to is the fact that someone who learns on his/her own, has a more accurate knowledge regarding errors mesages, time compiling messg, and almost any kind of the most strange errors messg that never occur on the real life !! :) I really like self teaching, altough every time I can, I take as much courses as possible. I learnt many things in that way, the first people who showed me Linux said three things That´s the way you get in That´s the way you get out That´s the way you get help! Now I at the same time I´m using Linux, I use FreeBSD too. By the way... now I´m dedicating time to asm. That´s really, really hard!! bye Gastón Again...

I need big Help! (Not yet another newbie question!)
Hi, I'm using freebsd 4.7 release with IBM dedicated server (P3-1133, 512 ram, 36 gigs hdd etc) I was happy with freebsd, before that I was using Linux redhat as server OS. Everything started at, when I want to install eDonkey client. It asked for Linux-Base package, and installed automatically (/usr/ports collection) Because eDonkey didn't work usual, and crashes, I de-installed linux-base with eDonkey. Everything was normal at this moment. When I try to upgrade my apache, with compiling PHP, Php-Accelerator, I noticed my Apache is using 150Mb ram from now on! Like this (a line from "top" command) 38016 nobody2 0 145M 8308K sbwait 0:04 0.00% 0.00% httpd it should use 10-12 Mb usually, and increase when child proccess number increase. But Apache start with 145-150Mb ram usage, this stays exactly like that in top command But when proccess increase, my swap ram getting filled, and server slowdowns a lot I asked for a freebsd upgrade (to my host) and they installed freebsd 4.7 (it was 4.5 release, when things happened) After that, I recompiled apache-php (with php-accelerator) again. Nothing was changed, it still uses 145-150Mb ram I am sure linux-base is responsible for that. Because when I use linux-sun-java-1.4.1 (a simple link checker with 20 threads) I see 200Mb ram usage. What can I do? Please help PS: Apache / Php compile configurations below Apache Step 1: with bash: EAPI_MM="/usr/local/mm-1.2.1" \ ./configure \ --enable-module=rewrite \ --enable-module=speling \ --enable-module=expires \ --enable-module=info \ --enable-module=log_agent \ --enable-module=log_referer \ --enable-module=usertrack \ --enable-module=proxy \ --enable-module=userdir \ --enable-module=so \ --activate-module=src/modules/perl/libperl.a \ --enable-module=perl make make install Apache Step 2: With BASH EAPI_MM="/usr/local/mm-1.2.1" \ ./configure \ --enable-module=rewrite \ --enable-module=log_agent \ --enable-module=log_referer \ --enable-module=log_config \ --enable-module=auth \ --enable-module=digest \ --enable-module=autoindex \ --enable-module=cgi \ --enable-module=dir \ --enable-module=env \ --enable-module=include \ --enable-module=mime \ --enable-module=so \ --activate-module=src/modules/perl/libperl.a \ --activate-module=src/modules/php4/libphp4.a \ --enable-module=perl Php 4.3.0: Deleted: --with-apxs=/usr/local/apache/bin/apxs \ ./configure \ --with-apache=/usr/local/apache_1.3.27/ \ --with-mysql=/usr/local/mysql \ --enable-track-vars \ --with-gd --with-freetype-dir=/usr/local/include/freetype2 \ --enable-ftp \ --enable-sysvsem \ --enable-sysvshm \ --enable-sockets \ --with-mm=/usr/local/mm-1.2.1 \ --with-jpeg-dir=/usr/lib \ --with-zlib-dir=/usr/local cp php.ini-dist /usr/local/lib/php.ini Add: zend_extension="/usr/local/phpa-1.3.3r2/php_accelerator_1.3.3r2.so" Fix: register_globals = On; __ Do you Yahoo!?

However, it's *not* caused me any problems, and even with 60 processes all reporting 145MB (145MB x 60 = 8.7GB) I use no swap. --daxbert To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message
