If you have enough space (which you do with 80 gb) it is a good idea to reserve a group or partitions for a re-install. What I have is : / 250 mb /var1g /usr5g that is unique to an installation. Others (/tmp, /home) are shared between installations. Then I have another /, /var, /usr for another installation. By doing this, I am able to do a complete reinstall while keeping the old one. This gives a fallback if the new one doesn't work correctly, and you keep your old config info. When I first installed Debian, the fallback was Mandrake. It is also handy if you are running an "unstable" system. Keep one before a "dist-upgrade" for when something gets removed or doesn't work. On my main machine, I have 2 drives, with 4 boot configurations. There is a duplicate /home on the other drive that I use for backup (with rsync). If you are setting up from scratch .. I have found that reiserfs works better on big partitions, and ext3 works better on small ones. If you are measuring in gigs, that is big. On a 20 gig partition, I get about a 4:1 performance improvement with reiser. I don't know about the other filesystems such as jfs. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

Several will take the folders, including kmail and mutt. (but mutt isn't GUI.) I use kmail and mutt sort of interchangeably. I use kmail at home, and mutt away from home when the gui is too slow. Since they use the same format, I can go back and forth between them. I used to do this with pine, but for me mutt has replaced pine. One thing I like about kmail (compared to other GUI mail programs) is that it does only mail. One "bug" in kmail is that it uses index files. If there isn't one, it will create it. If you change a mail file (mbox format) with another program, only a little, sometimes it won't discover that the index doesn't match and will give a messed up display. The solution is to remove the index file. Sylpheed uses a different storage format. I couldn't figure out how to go back and forth between it and a text program like mutt. That means you will have the same problem moving from pine. I don't like evolution for the same reason I don't like Outlook. A mail program should do only mail.

You may need to select "advanced" and manually configure scan rates and resolution, eliminating those that work but poorly. I recommend looking in the monitor manual and selecting scan rates in a narrow range so it can only choose the one you want. When I left the range wide, it chose 1280x960 on a 1280x1024 monitor, even though 1280x960 was not listed as a proper choice and 1280x1024 was. This resulted in a vertical smear over the whole screen. Another option is to manually edit /etc/X11/XF86Config-4 . Just specify the exact rates you want, and take out the others. Another comment on TFT monitors It is not enough to match the scan rates. Every pixel needs to line up, in the correct phase, otherwise you get smearing. It must be exact. Most monitors have a means of automatically matching it. You might need to activate it by pushing a button on the monitor. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

File systems -- reiser vs. ext3
I am trying to understand them. The basic question ... Why choose one over the other? Technically, what is different? My benchmarks seem to show that Reiser is superior, but they may be flawed. What I see is that it is faster and uses space more efficiently. I get about a 4:1 difference for an md5sum of a large .iso file. This was different partitions of the same drive. Later, I copied all out of an ext3 partition, reformatted it as reiser, and got the same 4:1 speedup. I have been using Reiser for a few years without trouble. (On the laptop since Suse first made it available as an option.) Does anyone know where I can find technical documentation on ext3? Does anyone have any hard data (as opposed to anecdotal like mine) to show the relative merits? (other than ext2 compatibility) Tech documentation of Reiser is available on his web site. I am looking for something comparable on ext3. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

My guess is that [EMAIL PROTECTED] isn't subscribed, and never was. There is some other address that you have used, possibly without your knowledge, at some time in the past that is subscribed. It is likely to be some variant. Perhaps your ISP changed its name, and you subscribed under the old name. Perhaps your ISP automatically changes all the names to the new one on all mail you send and receive. Perhaps your ISP told you to change your address, but keeps forwarding the old one. What do you get back when you try? If the address doesn't match, there is nothing anyone can do. The best way to trace this is to look at the headers. Most email programs hide most of the headers, so you need to do some extra work to see them. In there, you will find the complete routing that a message took to get to you, including intermediate sites it has been forwarded through. You may find a like like "Envelope-To" that probably refers to another or your email addresses, that you have forwarded so they all look the same to you.

I have one and use it occasionally. It is a modem, so it interfaces like a modem. No special software is needed. Some warnings . 1. It doesn't work everywhere. There are some places where it doesn't work at all, no matter how good the signal is. It has something to do with what kind of system you are on.

OK so far. It's more elegant to say:
struct t_my_type;
{
uint32_ta;
uint64_tb;
uint8_t c;
};
but I won't dwell on that.
It is not clear what uint32_t, uint64_t, and uint8_t are. Let
me assume that they are names of classes.
> // allocate some memory for an instance of this object

You left out the "*" in the cast. I assume this is a typo.
Actually, the cast isn't necessary. The C++ "new" is not just
another name for malloc. It gets memory using malloc, then
invokes a constructor to initialize it. This difference is
important. The cast isn't necessary because it already is the
correct type.

Hopefully. In this case, probably, but it cannot be guaranteed
to be true in general. When you use multiple inheritance, it
will probably not be true.
> // return the memory to free storage using the second
> // pointer
> delete p_b;
Delete is not the same as free. It first invokes the
destructor, then returns the space using free. Since you
changed the type of the pointer, you get a different
destructor.
Since you didn't define a destructor, by default it just calls
the destructors for all the members.
> I think the free store will be maintained properly because
> there is a control block attached to the allocated block of
> storage that defines the length of the allocated memory.
For this specific example, probably, but you can't count on it
in general.
Since you didn't say what uint64_t is, let me make a diabolical
definition of it.
class uint64_t
{
long* x;
uint64_t() {x = new long;}
~uint64_t() {delete x;}
};
Now, when I do:
t_my_type * p_a = new t_my_type;
I actually get the struct, but since uint64_t has a constructor
it is initialized. In this case, the initialization uses "new"
to get even more memory. So, you actually have 2 blocks of
memory.
If I do:
delete p_a;
the destructors will be called, deleting the hidden memory
block, then the real one gets freed.
If I do:
int * p_b = (int *) p_a;
delete p_b;
It doesn't call the destructors, so the internally allocated
piece is still allocated, and no longer accessable. It's a
leak.
Actually, you get the destructor for int, whatever that is.

You didn't say what your major is, so I am assuming it is CS. It is worth studying many languages, including those that do not seem to apply to your present interests. You are not expected to like them all. COBOL should be studied for several reasons. First, it uses a syntax that is more conversational than other languages. Also, it is has been and still is of significant historical interest. By learning it, and learning its style, you learn programming techniques that you would probably not be exposed to otherwise. Too many CS programs today put too much emphasis on a single style of program development, usually "object oriented". You can't really know what that is, or what its benefits are, until you contrast it against the others. Windows, too, has its place. Too many CS schools use MS-Windows exclusively. In my mind, this destroys their credibility. As much as I like GNU, Linux, free software,.. I must admit that an environment that is 100% GNU, Linux, free also is of limited credibility. You see only one side. A truly good program will use a mix of systems. A few years ago I taught a senior CS course "comparitive programming languages". There were assignments in FORTRAN, AWK, Prolog, and Lisp. We also spent some time on FORTH, and a little (too little) on COBOL. If I ever do that course again, there will be assignments in COBOL and FORTH. The only reason there wasn't is that I couldn't find appropriate free software in time. I do know where to find them now. In this course, it wasn't enough to just get a program working in each of these languages. I required them to be in the style of the language. Although you can make believe they are all C, I didn't accept that. I even enforced a "no assignment statement" rule in Lisp. FORTRAN here meant FORTRAN-IV, that is the 1966 version, that didn't have block if, so they had to use goto's. So, stop griping about COBOL. Do your best. Learn why it is the way it is, and how it influenced the more modern languages. Learn the style, so when someone gives you a COBOL-style program in C++, you will understand it. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

Change the "confirm" procedure The way it is now: When subscrbing the list sends you a message. You must confirm by responding to it, keeping the subject intact. Just "reply" does it. The body doesn't matter. Proposed change: The list sends you a message. You respond, keeping the subject intact, but in the body you must copy the "Received" headers from the confirmation message.

Maybe it is a problem that has nothing to do with the quality of the CD's. Here's my own experience ... I was having all kinds of trouble with bad disks.

I use mkisofs and cdrecord. After getting a bad one, I tried again from the same image file. Same errors. Check the file. It's bad too. (CD-RW, of course, for the experiments) It turns out the problem was the VIA DMA bug. It worked with DMA disabled, but a large partition with ext3 was now too slow to burn a CD at 4x. (Reiser on the same size partition was ok at 12x, with DMA off.) Fortunately, my motherboard also has a Promise controller on it. Use that instead, problem solved.

Log out, then log in again.
I get this sometimes after an upgrade (apt-get dist-upgrade).
"dpkg-reconfigure locales" alone doesn't do it. Logout, then in, then
it's back to normal.
If someone can explain why this happens, that would be nice. I am
guessing that it has something to do with locale being updated, but
some applications or dynamic libraries or something like that are
already running with the old one, so it gets a mix and complains.
As a more general hint .. I have found that often when things look
messed up after an upgrade, logout and in fixes it. Most other systems
require a reboot after an upgrade. If all else fails, try that.

Arc was released as source, before GPL was accepted by the community. Here is the original ARC license, in full: You may copy and distribute this program freely, provided that: 1) No fee is charged for such copying and distribution, and 2) It is distributed ONLY in its original, unmodified state. If you like this program, and find it of use, then your contribution will be appreciated. You may not use this product in a commercial environment without paying a license fee of $35. Site licenses and commercial distribution licenses are available. A program disk and printed documentation are available for $50. If you fail to abide by the terms of this license, then your conscience will haunt you for the rest of your life. PKARC was derived from the original ARC sources, in violation of the license. PK never released source. The original was just a fast ARC, then PK extended it to use different methods of compression, making it incompatible. The PK version had some critical parts hand coded in assembly language, and by far outperformed the original. > So- Phil sent out an email to all the BBSes, announcing > that his software would no longer be able to extract '.pak' files, > and suggested that we all use .zip instead. PKZIP/PKUNZIP is still > the defacto dos/win archive standard, and PAK INC... went out of > business. Point being, that it was not up to the judge, nor the > lawyers, it is up to us. PK's first change after losing the lawsuit was "pak" which was the same thing changed only to make it incompatible. Then it was replaced by "zip". The source for zip was never released, but PK did release specs that someone could use to make another program that was compatible. The InfoZip package available on Debian, and WinZip are both non-PK, from the specs. At the time, I believed like the majority, that Henderson was just jealous of his competition, because he couldn't keep up. In hindsight, now I see it Henderson's way.

My point was that both are the same in that the issue was that a "free" program with source distributed is illegally forked and taken proprietary.It is an example of a case that GPL is designed to prevent. Remember .. this happened at a time when GPL was not well known. The more usual was a shareware license, like arc.

I would go farther than that. My preferred setup is to have enough space to completely install twice. That way if I decide to reinstall or make a major upgrade, the other one is there for recovery.

True, but I think misconfigured smarthosts are more common than not. Comcast is one such misconfigured smarthost. Consider this ... A customer gets internet service by cable. The technican configures the modem. Customer doesn't bother to get an email address in the provider's space. Instead, uses some other address and picks it up by POP or whatever. When sending mail, puts that address in "From". Having nothing else to go by, that becomes the "Return Path". That is what is considered to be proper operation. As a result, for improper action, anything goes for that address, so spammers and viruses can do what they want. This is another reason why it is bad to force the use of a smart host. They launder the mail, so it becomes impossible to find where it really came from. Perhaps this is the intent. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

EXIM configuration question

Then if it fails delivers through the ISP's relay. Background ... It's easy to configure it to always deliver directly. That works except for certain sites (AOL) that block addresses that are listed in dynamic IP blocks. (well known problem) It's easy to configure it to always relay through my ISP's relay. It's easy to have certain listed destinations delivered through my ISP's relay, and those not listed delivered directly. I am using: Exim version 3.36 #1 built 11-Dec-2003 11:35:23 on sid.

Here's a better idea. Ask him why. Probably he doesn't consider it to be as bug. Maybe "upstream" requires sendmail, and doesn't work with exim. Ask him why. Probably he doesn't consider it to be a bug. Maybe he never thought of it. Actually, it doesn't seem odd to me at all. Debian has lots of packages, and often provides several alternatives for a job.

Yes. Be more respectful of people who are trying to help you. You say "not expensive" indicating your willingness to pay something. How about paying for improvements you want? You say you are a system administrator, EE, and consultant. How about providing some services to a project you would like to see improved? You say "are crap". How about some detailed info on what is wrong and how it can be made better? The projects you mention are starved for resources, as are many free software projects. The subtleties go a long way. In most significant free software projects, the authors are fully aware of the problems, but lack the resources to do much about it. You have been here a while, and certainly must know how free software works. How about taking on one of the problems yourself, solving it, and contributing the solution?

You must realize that all software was only half working at some time. For commercial software, investors keep it going past this stage. For free software, the investors are the developers themselves, and the users that are willing to put up with it, and carry it through. There's also the factor of "which half", and where is it going. The zero-cost non-free software gets its funding from investors, and carefully chooses "which half" to make you buy something bigger. Another point on "half working" software is that sometimes there are multiple competing projects, each "half working" but a different half.

I agree that there are times when we must put idealism aside to get something done. Some projects can only be done in a commercial environment, with big investors. I understand your decision here. You just might need to use Windoze here .. Pads, perhaps??? Even so, with wishful thinking ... a little participation in the free project goes a long way, if it is done constructively. "I would really like to use your x, but because of (some detail) I feel forced to use y. It's so close, but." Some commercial products cooperate with Free/open-source software. Some try to undermine it. It is important to know the difference. The zero-cost crippled demos undermine it. There are big packages that use Free/open-source commodity packages and provide added value at a price. They support it, especially if they help fund it. Sorry if I sound overbearing here .. I am working on a project (very close to geda) which is now "half working" and realize how little things like this impact progress on a project. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Have you looked at kicad? Supposedly, it is less powerful than PCB (geda) but more intuitive. My experience is that kicad is less intuitive, because it has a MS-windoze look and feel, with the extra baggage. I'm curious what you think about it. Again .. some friendly communication with the developers should help a lot. Making software intuitive is hard. It's mostly in how it behaves when you do something wrong.

That kind of bugs is very hard to find without users who are willing to try it, report the experience, and work with the developers to improve things. > What I need is a PCB-Autorouter which do the routing for > me!!!

You might as well have written:
class A{
public:
void f(int a ){a++;};
};
class B : public A{
private:
virtual void f(foo a){};
};
f in B has the same name as f in A but different args.
This is usually a mistake, so they made it illegal.
If you override one f, you need to override them all.
(or change the name)
To fix:
class B : public A{
public:
void f(int a){A::f(a);}
private:
virtual void f(foo a){};
};
Now, try this:
class A{
private:
virtual void f(foo a)=0;
};
class B : public A {
private:
virtual void f(foo a){}
};
This doesn't work either, because f in A is private, so B
doesn't know it exists. I don't know what it will do. I think
you get 2 f's, and still can't make an instance of B because f
is pure virtual. Change the private in A to protected, so B
will see it.
It really is off topic
