Hapends even to big RedHat.. Apparently, Anaconda knows only to detect MORE THEN 4GB. If I have 4GB, then it installs the standard kernel which only recognizes 3GB (iommu doesn't work). So the PAE kernel needs to be installed if => 4GB and not only if >4GB :) Thanks, Hetz On 5/6/07, Noam Meltzer <[EMAIL PROTECTED]> wrote: http://www.redhat.com/docs/manuals/enterprise/RHEL-5-manual/release-notes/RELEASE-NOTES-x86-en.html During the installation process, Anaconda will automatically choose the kernel package to be installed. The kernel selected by default does not allow Red Hat Enterprise Linux 5 to detect more than 4GB of RAM. As such, if your system has more than 4GB of RAM, you need to install the kernel-PAE variant of the kernel after installation. Note that this does not apply when a virtual install is performed. I assume that maybe they ment "3GB"?

That's true, but...

No. Let's see:
$ strace tputs cols
..
ioctl(1, TIOCGWINSZ, {ws_row=55, ws_col=132, ws_xpixel=0, ws_ypixel=0}) = 0
..
So this utility looks at the terminfo database, for terminal
features, but also (in "modern" versions) use the ioctl() mentioned
by Nadav to query the tty driver.
> ncurses being 5th?
No. Ncurses is just a hi-level library (for some definition of hi-level ;-)
working above terminfo (used to work above termcap in Berkely Unix) and
provide more abstractions (e.g: [text] windows, scrolling management,
cursor motion, etc.)
Just to complement what Nadav already describe, if you happen to work
in an old shell that does not contain signal handling for SIGWINCH and
change your xterm size, the standard workaround is to run:
eval `resize`
Which issues the ioctl and output the commands to set COLUMNS and LINES
environment variables.
You may notice that the output of resize depends on the $SHELL environment
variable, so it may be used both by sh/ksh/bash and csh/tcsh.

I completely missed this question (which has nothing to do with bidiv). So here is a brief history of COLUMNS... COLUMNS is a variable set by your shell (zsh, bash, tcsh, or whatever you're using). The idea is that your shell knows what is the width of your terminal and passes this knowledge to the programs it runs; A few of the familiar Unix programs use this knowledge - for example "ls" by default shows the file listing in multile columns, up to the terminal's width. As you saw, bidiv also uses this variable. In the "old days", terminals used to have fixed widths; If you had a vt100 terminal (TERM=vt100), then the width was always 80. If you had a AT&T 5620 terminal, the width was 88, and so on, and the "termcap" or "terminfo" libraries was used to get this information based on the terminal name. However, when resisable windows appeared in Unix (on the aforementioned 5620, and in X-Windows), this fixed width was no longer enough, and the terminal's (or actually, terminal emulator window's) width could be changed at any moment. This is when three new facilities were added to Unix. First, a window width/hight setting was added to the tty (the "tty" is the Unix mechanism for a terminal emulator to connect to a process, usually a shell, running in it). See "stty -a" (and the TIOCSWINSZ ioctl). This was almost enough - your shell and the processes it runs can now figure out at any moment what's the window's current size. But should the shell (which needs to know the terminal's width, e.g., for command line editing) try this ioctl on every command? Instead of forcing it to check every time, a new signal was invented - SIGWINCH, "window change". When the terminal emulator is resized, it sends its child process (namely, your shell) a SIGWINCH signal. The shell then uses the ioctl to get its current window size, and remembers it. The third mechanism is a shell variable, COLUMNS, which gets updated when the shell learns of a new window width. This feature is useful because ioctl's are "nonstandard" or "complex" and using variables is easier; it also allows the user to easily override the width; And it also works with pipes and redirections. Learning something new everyday. What is tput then? I know it speaks with the terminfo db and that it's a "rather portable" to method to encode color strings (try tput setaf 1; whoami; tput setaf 7).

Hi, Thanks for the last answer. The only connection is that, when one does not specify the width, bidiv uses the $COLUMNS value (see bidiv man page). It so happens that 1-My old version of bidiv does not like odd values for the width, 2-The number of columns of the xterm, as stated in .Xresources was an odd number. Hence the harmless, but intriguing error messages. The apt-get upgrade bidiv asked me to replace a lot of additional packages. As, as a rule, I prefer to upgrade by several small steps (only apparently I negected this for a long time), and I have no real problems with bidiv, I prefered to answer: don't!

Re: flash or java
First, performance wise (calculations and stuff), Flash should be ok since their scripting engine (ActionScript) is basically JavaScript with a good JIT engine.

4GB Memory question
Hi people, I have here 2 "think center" machines, each with 4GB RAM each and I'm using CentOS 5 with them. BIOS reports correctly that the machine has 4GB RAM, however Linux begs to differ: # free total used free sharedbuffers cached Mem: 3098212 2356962862516 0 16608 164824 -/+ buffers/cache: 542643043948 Swap: 4096564 04096564 So BIOS says "4", Linux says "3". What kernel parameters can I use to "convince" Linux that I really have 4GB RAM? I don't think I need the HUGEMEM kernel since it only deals with >4 GB RAM and RedHat has "united" all the bigmem stuff into 1 kernel. Any suggestions?

Flash has some built-in support for microphone/camera, but only starting at certain version (7? 8?) and obviously it is not as full as a locally running application. Java's support for this kind of things tends to be more limited. Also think - will the target audience have the necessary software installed (right version of Flash/Java) or will they be curious enough to go and install it? Regarding math - once again, all depends on your actual requirements. I am not familiar with Flash's script language, but Java should be sufficient for almost everything you want (a Turing-complete language after all). But Flash can use JavaScript - would that be good enough? Legally - if you use Sun's Java classes only you don't have to pay anyone.

I'm afraid I didn't understand what you just said. Did you try to compile version 1.5 (using the link I gave), and the bug is still there?
