Gui interface ideas
I have setup a series of programs for controlling/monitoring/testing some hardware through a serial port that are all command-line based. The engineers working on the project were fine with this, but as they go into production, they need a more dummy-proof interface since they will have many people testing that don't know this as well. I was looking for a good way to make a quick gui, ideally independent of the current programs. I've looked at using something as simple as a shell script wrapper using dialog for the interface to using mozilla's framework for writing a nice gui environment. Other ideas are doing ncurses in perl since my existing scripts are all in perl or even perk/tk or perl/gtk. The last idea was develop a web-based interface since it's easily accessible from other computers. ncurses might be quicker and fit the bill, though I may still want a gui. It would also be nice to be able to run this from a windoze computer. -- I sense much NT in you. NT leads to Bluescreen. Bluescreen leads to downtime. Downtime leads to suffering.

Actually, I believe it's the other way since open() is the low-level system call to the kernel to actually open the file and the f*() functions like fopen() all really use the kernel system calls like open(). The reason that programs like aoss can work for programs is because glibc that provides fopen() has hooks inserted to catch it before the call to open(), but once you're inside the kernel it's too late to catch it. > > Hope that helps. > > > > -- > Steven Yap <[EMAIL PROTECTED]> > > > -- > To UNSUBSCRIBE, email to [EMAIL PROTECTED] > with a subject of "unsubscribe".

Replicating Debian Systems
I may have to rapidly deploy multiple debian systems that will have the same software installed and be configured the same way. The ideal way to install debian would be to stick a cd into a computer, turn it on, and come back a couple hours later. If I could make a custom cd to do just that and maybe d/l the packages off of the web or another computer that don't fit on the cd would be nice. I also have some of my own software to install and also need to modify files like .profile in the users home dir as well as setup one users with password on the system. Maybe I'll have to learn how to make deb packages. I don't want the installer to ask questions for each packages like exim's mail configuration. I know I can turn it off by modifying a file and telling them to be silent, but instead I'd just like to have a text file that specifies the correct answer to all of them. Does debian provide a way to do this? My last problem is that some software is too old in stable, I've had to upgrade several programs including XFree86 on some systems already installed. I know about backports.org, but some programs like gnuplot don't have a backport, and I'm debating about using testing/unstable, but I want to believe that the system will be stable since I won't be down there most of the time and ppl who know nothing about linux will be using it. -- I sense much NT in you.

OT: Linux 2.6.0-test9 Running for 24 hours!
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I've just recently install a test kernel for linux 2.6 and I've had it running solid for 24 hours running in X!!! Sorry, but just had to let out the excitement as this is the first time I've ever tried running any kernel that was not considered an official stable release. I've noticed several other people have been running linux 2.6 so I was curious if somone could answer a few questions. I've noticed swapd is running at 98-99% cpu usage, but it doesn't seem to be majorly impacting system performance, any clue as to why or what I should look for? Also, when I load the mouse driver after X has started, (as it isn't auto-loading for some reason), the mouse jumps around for a few seconds before I can use it. Also, now when I restart into X using my Linux 2.4.22 kernel, the keyboard doesn't work at all. I have to ssh in from another machine to kill X so I can access the console where the keyboard works fine. I'm using XFree86 4.3.0 which I manually installed and re-running the install script didn't seem to help. Now I seems to be forced to use the test kernel if I want X windows.

Something that C actually does better than > C++ in regards to higher-level functions? I can think of a few reasons myself: 1) Compatibility 2) Speed 3) Portability 1) Libraries are a good thing to be written in C unless they are specifically releated to a programming language that is not C like the standard C++ libraries. It is very easy to write a wrapper for a library written in C for use in other languages like Perl, Python, C++, Java, Ruby. But much harder to write a wrapper for a C++ library to use in other languages like C, etc. The Arts client libraries are a good example of that situation. The libraries are written in C++ with a special library that acts as a C wrapper. The problem is the wrapper library is severly limited compared to the C++ libraries, my guess is the programmers got a little lazy when it came time to write the wrapper and it has caused me some trouble trying to use the libraries. Also, any C library can be used in C++ without a wrapper, but a wrapper is required for the other direction. And have you ever tried to open a C++ library using dlopen()? It requires at least one C function to start with since all the C++ functions names are mangles. It's doable, but a little bit of a pain. Lastly, C has more libraries for a user programs then any other language except C++ of course. 2) C is just faster than C++ and much faster then almost any other choice as far as code speed. Even when I'm writing in C++ I will use fopen() and fprint() for file I/O then the C++ equilelants because they are noticably faster. C++ with never make it into the kernel for this reason along with others. 3) C is more portable then C++. I can take almost any C code and use it with almost any C or C++ compiler or even other variations like Objective C or Dynamic C with very few problems. Most exceptions are maybe use of newer features of C like ## or enum or directives like #pragma. In some enviorments C is the only way to go, other languages like Cobol, C++, or Perl are just too high level. Once case is the TI-89, it's to limited to run C++ effectively. I've never seen anyone even attempt to write a C++ compiler for it. Other embedded systems like Microchip's PIC microcontrollers are just barely leaving asm for C now, it will be a while before they will support C++. Rabbit Semiconductor sells a Z80 based microchips and they created a language called Dynamic C which is basicly C with special support for state machines. It won't do C++ either. If people don't learn C before C++, it A) a little harder to learn properly, and B) it's harder for them to learn other languages later like C, Objective C, and Dynamic C with are all C dirivatives.

Do we still really need kudzu still now that linux has hotpluging support for usb, pci and firewire? Maybe for supporting old isa hw. Even though it's called hotplug, it should be able to also detect hardware on the initial boot as well, it does for usb by calling usb.rc, why can't there be a pci.rc that does the same thing and at least parially remove the need for kudzu and Xconfigurator.

Good Debian-based distro
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I'm looking for a good debian-based distro with a good and user friendly install program. I love debian much better than redhat based distros mostly for the packaging system, especially all those apt-* commands. Though for my less linux experienced friends, I have to install debian for them if I want to get them to use it. I've heard of Libranet, Corel, and Xandros OS that are debian based but haven't tried any of them. Any recommendations or should I just have them use redhat or mandrake? - -- I sense much NT in you.

Re: Linux firewall vs Windows and Hardware based firewalls
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Does anyone have recommendations about linux vs. openbsd? I have always used linux for everything and propably still will for the most part, but for security, would it be better to use openbsd? - From what I hear, openbsd is a variant off of netbsd, but built with security at it's top priority where linux is usually pushed more cutting-edge and I'm sure a little less stable at times compared to openbsd, but still much more stable then windoze. I don't know how the firewalls compare in features though. Would it be worth it to play with openbsd some or should I just stick with linux? - -- I sense much NT in you. NT leads to Bluescreen.

All-in-one flash card reader.
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I have a usb flash card reader I bought for my debian box and I tried to plug it in with a flash card to test it and couldn't get it to work. I know the flash card is valid, it works on linux with a different single type flash card reader, but not with my 5 in one flash card reader. usb-storage loads and dmesg reports a new scsi drive at sda. I've tried mounting /dev/sda and /dev/sda[1-4], but only get input/output errors. My only guess it that linux it trying to read a different slot which has nothing in it.

Dpkg seg faults.
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I was trying to upgrade libxml2 to the latest 2.5 version recently so I could install ardour. I created a dummy libxml2 package using equiv-control and equiv-build. The package installed ok, but ardour still failed and I discovered I also needed to replace libxml2-dev, I used the same procedure to create a dummy package for it, but when I tried to install it, dpkg segment faulted. I can do some basic querying like dpkg -L, but if I try to install or remove anything, it seg faults. Even worse, I can't use apt-get anymore since it's complaining about a failed dependency for libxml2-dev since it needs libxml2-2.4.19 and I have libxml2.5.7 installed. I'm using debian 3.0r1 with a customized linux 2.4.20 kernel. Here is the output created by dpkg -i libxml2-dev_2.5.7_i386.deb: Selecting previously deselected package libxml2-dev.
