    new Knoppix version optimized for distant learning?

    Hi. I have an old laptop 2 GB ram, T2500 CPU.
    It was working fine with Win XP. But by no reason XP is no longer useful.
    I used win 7. Unfortunately laptop went too slow.
    Then I tried Knoppix 8.6. It worked with acceptable speed.
    I had intention to use this laptop for distance education - for zoom, google meet, discord and ms teams.
    I started with ms teams and what happened?
    It seem that Microsoft actively prevents using windows software on linux.
    For example ms teams web app did not start. There was many login errors, and after log in , there was ridiculous message: "we could not log you in". And when i try to log in again there was message: "you are already logged in".
    I try to install ms teams for linux. Windows installer takes minutes to download , but linux package took 1 hour. So microsoft actively restricts download speed for linux packages.
    In knoppix with .rpm there was error in synaptic package manager. With .deb there was message that package is for amd64 but knoppix is i386. It seems that knoppix start 64 bit kernel , but all other libraryes are still 32 bit. And that made using of ms teams impossible.
    So i was unable to use knoppix for distant learning. I believe using of Knoppix for distant learning is possible, but unfortunately i have no necessary skills to make it by my self.
    And i think it is good idea to make special knoppix distribution specialized and optimized for distant learning and conferencing.
    So what do you think?

    Thanks
    Best regards.

    Knoppix is not 64bit OS, it is a 32bit OS. Although some commands shows that it is:
    Code:
    knoppix@Microknoppix:~$ lscpu | grep Architecture
    Architecture:        x86_64
    knoppix@Microknoppix:~$ uname -a
    Linux unknown 5.3.5-64 #16 SMP PREEMPT Wed Oct 23 02:08:38 CEST 2019 x86_64 GNU/Linux
    knoppix@Microknoppix:~$ arch
    x86_64
    knoppix@Microknoppix:~$
    But the above results are false, maybe because "knoppix64" is also a "false" 64bit mode. Its role is only (if I am well informed) to support big size memories. The "truth":
    Code:
    knoppix@Microknoppix:~$ file /sbin/init/
    sbin/init: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=63e36b249ae01d0a8b4af3ae2689bd5463b86bdb, stripped
    knoppix@Microknoppix:~$ dpkg --print-architecture 
    i386
    knoppix@Microknoppix:~$ getconf LONG_BIT
    32
    knoppix@Microknoppix:~$
    So, do not try to install 64bit applications, it is impossible in Knoppix. And MS Teams has only 64bit installer. Unfortunately, more and more applications have only 64bit installers nowdays...
    But even for a 32bit package, it is not 100% sure that you can install it, because Knoppix is made up from more Debian versions, and could be a conflict with a new app install. I recommend to install a new app first in live mode and if it was OK you can install it in persistence mode.

    RPM: Knoppix is based on Debian, you have to use DEB packages for installation. RPM packages are for other distros (e.g. OpenSuse).

    Softwares: Debian/Knoppix has a lot of apps. I do not use "distant learning and conferencing" apps, but should be there such applications, too. Before trying to install something in Knoppix make sure that it has not an app that can accomplish what you want. It is very likely that such software is already installed there...

    Hi ialtaparmakov

    I am not sure to well understand your project.
    Some observations nevertheless (I am not vey acquainted!).

    1- Why do you want to MIX tools fairly dedicated for
    windows_system with a fairly different OS_System_LINUX?

    2- Knoppix offers the program "Wine" which does not work
    for all Win32 programs!
    Please have a look on the "Wine" web site...

    3- Plese look at other forums namely "windows ones"

    4- If you have Windows_XP (or /and Win_7) I guess that
    your laptop may be not only old but "VERY OLD" like
    oneof mine!
    The processor is fairly "OUDATED" for "modern" programs.
    "Unfortunately" that is the trend of "tecnology (ies)"
    and of "THE" "progress"...
    You cannot expect well doing "New Things" with such a
    processor...It was my unfortunate experience.

    Courage , patience and good luck for your difficult project
    as I have understood it.

    I am very rarely connected to the forum.

    Greetings
