Linux al rescate

Recupera tus datos de Windows…EN y ES

Por lo visto Micro$oft NO tiene mejores aplicaciones que las Open Source (GNU/Linux) para recuperar datos en sus sistemas operativos!
Claro que hay otras soluciones profesionales para recuperar datos de M$Windows, pero no son desarrolladas por M$ y cuestan un ojillo de ciertos avatares anti Linux.
Port25 de Micro$oft es el nuevo subdominio de technet.com dedicado a la comunicación de la comunidad del software GNU, las aplicaciones de código abierto y las libres con la empresa que apuesta a tener su códigos cerrados!, que aprovecha el trabajo de la comunidad irónicamente combatida durante décadas por la misma empresa Güindos como "aplicaciones dudosas y de baja calidad".
Se han rendido ante la estabilidad, confiabilidad y la clara supremacía tecnológica del Software Libre y de Código Abierto (F-OSS)
Lo que Micro$oft no podía superar tecnológicamente o le hacía competencia, lo compraba (Virtual PC) o lo destruía con su propaganda o sus inversiones millonarias (e.g. Netscape) o el falso intercambio tecnológico (e.g. Real) o la implementación cerrada de sus aplicaciones (e.g. NTFS como sistema de archivos cerrado).
Cuando la empresa con mayores ingresos del planeta vió que en menos de media década Linux le aventajó tecnológicamente, ni se puede comprar a Linux y las aplicaciones del grupo GNU y como no lograron poner en descrédito la superioridad de Linux como sistema operativo para servidores confiables, antes de acabar como gran perdedor, prefirieron unirse al ganador!
Buena estrategia de los que siempre trataron de ridicularizar a las aplicaciones de la Comunidad del software libre!
Hoy sólo puedo sonreir mostrando toda la dentadura soltando algo así como mi mejor carcajada!

gracefully as it ought.
-----------------------------------------------
Red Hat 3 Enterprise Linux Issue:
I am using a software RAID 1 (mirror) on two drives and the first drive has failed or been physically removed. When trying to make the second drive bootable, grub-install fails telling me '/dev/hdx does not have any corresponding BIOS drive.' How can I make this drive bootable with GRUB?
Resolution:
Release Found: Red Hat Enterprise Linux 3

Symptom:
When the first disk of a software RAID has been removed, the second drive is not bootable. Performing a grub-install fails with the error message: '/dev/hdx does not have any corresponding BIOS drive'.

Solution:
Please note that before performing any of these steps, you should have a recent backup of your important data. If for any reason the primary drive becomes unbootable, you should have your Red Hat Enterprise Linux CD #1 available in order to load the rescue environment.

If you are attempting to run grub-install inside of a rescue environment, you will need to first manually mount the corresponding disk partitions. You can view the partitions with the command:


# fdisk -l


You need to mount any partitions of type Linux or Linux RAID autodetect. In the following example of fdisk output, the /boot partition is /dev/hda1 and the / partition is /dev/hda2:


Device Boot Start End Blocks Id System
/dev/hda1 1 13 104391 fd Linux raid autodetect
/dev/hda2 14 1288 10241437+ fd Linux raid autodetect
/dev/hda3 1289 1352 514080 82 Linux swap


In this example, you would mount the partitions and chroot using the following commands:


# mkdir /mnt/sysimage
# mount /dev/hda2 /mnt/sysimage
# mount /dev/hda1 /mnt/sysimage/boot
# chroot /mnt/sysimage


The next step is to edit the file /etc/grub.conf (which is a symbolic link to /boot/grub/grub.conf). Uncomment the following line by removing the pound sign (#) at the beginning of the line:


from:
#boot=/dev/hda

to:
boot=/dev/hda


Now, to make the drive bootable, GRUB must be installed to the master boot record (MBR) of the disk. To do this, execute the following command (as root) to enter a GRUB shell:


# grub --batch --device-map=/boot/grub/device.map
--config-file=/boot/grub/grub.conf --no-floppy


Now, from the GRUB shell prompt, execute the following commands:


grub> root (hd0,0)

grub> setup (hd0)

grub> quit


The setup command within this shell actually writes GRUB to the MBR, which makes the drive bootable.
----------------------------------------------------------------------------------------

Q. After windows XP installation I lost my Grub boot loader and now when I try to run grub-install command to restore Grub in master boot record. But I am getting an error that read as follows:
/dev/sda does not have any corresponding BIOS drive

How do I fix this problem?

A. grub-install is use to install GRUB on your drive. If you are getting error try to recheck device map.

Type the command as follows:
# grub-install --recheck /dev/sda

Where,

  • --recheck: Probe a device map even if it already exists
  • /dev/sda : Replace /dev/sda with your actual device name.

Above command should fix the problem.

Restore Debian Linux Grub boot loader

Recently my hard disk went bad (some bad sectors developed), my boot.ini (Windows XP boot file) corrupted. I was using NT boot loader to load Linux. So I need to repair the Grub i.e. restore Grub in master boot record (MBR).
1) Press ALT+F2 (or ALT+CTRL+F2) to get shell prompt
2) Then get the partition tables for the devices using fdisk command:
# fdisk -l

3)When you type fdisk -l, you should see your partition name: /dev/scsi/host0/bus0/target0/lun0/part1 (for IDE disk it display same device file in IDE directory)

4)Once you identified your device file, mount disk using mount command:
# mkdir /mydisk
# mount /dev/scsi/host0/bus0/target0/lun0/part1 /mydisk

5) Next use chroot command to start interactive shell with special root directory i.e. /mydisk will act as root directory.
# chroot /mydisk

6)Use grub-install command to reinstall grub (SCSI disk):
# grub-install /dev/sda

If you have IDE device following command :
# grub-install /dev/hda

Again replace /dev/hda and /dev/sda with your actual device names.

7)Type exit and reboot the system. You should see your GRUB and Linux again.
# exit

Other choice was to use Linux Live CD (e.g. Mepis) and do the above procedure. Well, I could have used the Mepis to watch TV but I had some data and emails in Tunderbird so I opted to restore the Grub.

GnuParted Live CD
Educastur.es
sourceforge1 es diferente a sourceforge2
GPARTED-CLONEZILLA LiveCD

LiveUSB

Since 0.3.4-x version, GParted LiveUSB can be created from the iso LiveCD.
So there is no need to download another file !

To use the LiveUSB,

-either download this file in the directory where you have downloaded the iso file,
untar it (tar -xjf set_usb.sh.tar.bz2), become root and run it (sh set_usb.sh),

-either follow these simple instuctions (before 0.3.4-3):

(1) Create a fat16 partition on the usb stick and make sure it's flagged "boot".

(2) Copy from the livecd all the files from isolinux and syslinux directories
and gparted.dat file too, to the usb key.

(3) UMOUNT the usb stick and execute this command:
syslinux -s /dev/sda1
(imagine sda1 is the partition of your usb key ; but it could be something else such as sdb1.

You may find a complete description of the steps to follow at the forum !

-either follow these simple instuctions (since 0.3.4-3):

The second step is a bit different since there is no more isolinux directory !
You need to copy gparted.dat, and both gparted and gparted.igz files from boot/ directory,
and also all the files in syslinux directory, to your usb-key.

dd and rsync in Linux

The disk dump command, founded in Linuxquestions.org
and another info

Duplicating smaller partition, or drive to larger partition, or drive; or vice versa:
unmount before format the partition:
Code:
mkfs.ext3 /dev/sdXX
mkfs.ext3 /dev/hdZZ

Delete lost+found directory in the new partition and then mount it
mount -rw /dev/sdXX /mnt/sdXX

Example: You want to sync the root directory tree to another drive, but the other drive is larger.
If you use dd, you will get a file system that is smaller than the larger destination drive.
In this case you want to sync files, not the file system:
Format and mount the destination drive.
Code:
rsync -avH  /mnt/source_drive/* /mnt/destination_drive/
will sync all the files as files.
Rsync preserves the target file system.
If the second drive does not have the same structure of the logical drives, then don't forget to reedit the /boot/grub/menu.lst and the /etc/fstab in the /mnt/sdXX
You need to run:
Code:
grub-install
update-grub
from a the rescue menu of an installation CD/DVD for the target to become bootable.
If the target was bootable previously, it remains bootable.

How to Backup Entire Linode to another Disk Image

Debian tip

Move /home to it’s own partition

de un weblog de ubuntu:

Having the “/home” directory tree on it’s own partition has several advantages, the biggest perhaps being that you can reinstall the OS (or even a different distro of Linux) without losing all your data. You can do this by keeping the /home partition unchanged and reinstalling the OS which goes in the “/” (root) directory, which can be on a seperate partition.

But you, like me, did not know this when you first installed Ubuntu, and have not created a new partition for “/home” when you first installed Ubuntu. Despair not, it is really simple to move “/home” to its own partition.

First, create a partition of sufficient size for your “/home” directory. You may have to use that new hard drive, or adjust/resize the existing partition on your current hard-drive to do this.

Mount the new partition:
$mkdir /mnt/newhome
$sudo mount -t ext3 /dev/hda5 /mnt/newhome

(You have to change the “hda5″ in the above to the correct partition label for the new partition. Also, the above assumes that the new partition you created is formatted as an ext3 partition. Change the “ext3″ to whatever filesystem the drive is formatted to.)

Now, Copy files over:
Since the “/home” directory will have hardlinks, softlinks, files and nested directories, a regular copy (cp) may not do the job completely. Therefore, we use something we learn from the Debian archiving guide:
$cd /home/
$find . -depth -print0 | cpio –null –sparse -pvd /mnt/newhome/

Make sure everything copied over correctly. You might have to do some tweaking and honing to make sure you get it all right, just in case.

Next, unmount the new partition:
$sudo umount /mnt/newhome

Make way for the new “home”
$sudo mv /home /old_home

Since we moved /home to /old_home, there is no longer a /home directory. So first we should recreate a new /home by:
sudo mkdir /home

Mount the new home:
$sudo mount /dev/hda5 /home
(Again, you have to change “hda5″ to whatever the new partition’s label is.)

Cursorily verify that everything works right.

Now, you have to tell Ubuntu to mount your new home when you boot. Add a line to the “/etc/fstab” file that looks like the following:

/dev/hda5 /home ext3 nodev,nosuid 0 2
(Here, change the partition label “hda5″ to the label of the new partition, and you may have to change “ext3″ to whatever filesystem you chose for your new “home”)

Once all this is done, and everything works fine, you can delete the “/old_home” directory by using:
$sudo rm -r /old_home

Cloning a partition

Dragon43
March 7th, 2007, 03:15 AM
An update of that:
I finally got a copy / clone made using the "Ubuntu" live CD and used the terminal on that to get the clone of my 41 Gig's drives done in 57 minutes by using the command that MrC led me to with hints from a lot of people.
I used
{ubuntu@ubuntu:~$ sudo dd if=/dev/hda of=/dev/hdc bs=1M}
hda and hdc are the two physical places of my hard drives. 'a' is master on IDE 0 and 'c' is master on IDE 1.

I have the 'Rescue' CD now and the G4L CD and I will keep trying to get them to work for me also. Lots to learn and now that I have a good copy of my work to this point, I'm using the back-up or clone HD now with the original in a drawer, I can now mess things up without fearing I will lose it all.....

Acceso a NTFS y ext3fs

Cuando intento ver el contenido de la carpeta windows me dice que no tengo los permisos suficientes para verlo … que hago??

3. raseck - Enero 30, 2007

Intenta con esta línea en el /etc/fstab

/dev/hdaX /mnt/windows ntfs auto,ro,exec,users,dmask=000,fmask=111,nls=utf8 0 0

( Todo en la misma línea )

Luego desmonta y vuelve a montar la partición como root o anteponiendo sudo si usas ubuntu:
umount /mnt/windows
mount -a

error in ext2fs
1. boot with the kernel command line: init=/bin/sh since debian's single-user mode gives you most filesystems already mounted.
2. run fsck (read the man page to give you the options appropriate to your root fs); run it on all your filesystems.
3. shutdown -h and power-cycle.
4. run aptitude update then upgrade anything required.
5. reboot. Watch the screen for any errors on shutdown that would suggest that the system isn't, e.g. remounting the / fs ro before halt/reboot. If in doubt, set up a serial console and log the output or set up the console output to go to a printer.
6. If you still have problems, boot knoppix (I use grml) and run fsck. If this is ext2/3, I'd run -c -c so that the entire disk gets read to force the drive firmware to re-map any bad sectors.
While this is running, I'd be watching /var/log/syslog for any errors from the drive.
7. Ensure that you have SMARTmontools installed and run a long smart test and when its complete, check the results on the drive.
---
If all else fails, plan for a reinstall (ensure that you have backups).
Then boot knoppix and run wipe on the drive. This fully exercises the drive to exorsize any gremlins. Then install etch minimal (don't select any tasks), ensure that aptitude is installed (if it isn't, then apt-get aptitude), get aptitude set up the way you like with only necessary packages marked as manual, the rest as automatic, then do an update and upgrade before you install any other packages.

At each stage, do a
shutdown -rF.

Windows XP vs. Xandros Linux

ASUS Eee PC Face-Off: Windows XP vs. Xandros Linux

The Verdict

When you look at the final scorecard, the Linux-powered Eee PC wins by a TKO, taking four rounds and fighting to a draw in the productivity round. The XP Eee PC wins three rounds outright: peripherals, multimedia, and adding applications.
Ultimately, deciding which Eee PC is best depends on your personal preferences. Windows XP may be the preferred choice by many users because of its familiarity, despite the fact that you have to do a fair amount of scrolling in some applications. It's also the better choice if you want the ability to install popular programs, and if you don't want to worry about which peripherals will work.
If you’re looking for a faster computing experience, longer battery life, and don’t intend on adding much software, the Linux-based version of the Eee PC should be right up your alley. The Linux Eee PC's tabbed-based interface won't be all that familiar to Windows users, but it's arguably the more user-friendly solution for a 7-inch screen.

Winner: Xandros Linux Eee PC

UUID

stable root device
Given: server with SCSI disk for the system plus a SCSI storage in the back. The SCSI disk uses another driver than the SCSI storage. Installing Debian etch via grml is no problem, the system disk is /dev/sda, the SCSI storage is bound to /dev/sdb. But: who guarantees that /dev/sda is always the systemdisk? Using the Debian-kernel with initramfs isn’t capable of booting the system via root=/dev/sda1 because /dev/sda1 corresponds to the SCSI storage. (Side-note: the grml-kernel does not have this problem, it just boots the system without any problems at all. 8-))

Generic solution: use the power of UUID:

root@grml # /lib/udev/vol_id /dev/sda1 | grep UUID
ID_FS_UUID=4a6aed11-42dd-4c82-81ce-8f469e93f210
root@grml # eval $(/lib/udev/vol_id /dev/sda1 | grep UUID)
root@grml # ls -la /dev/disk/by-uuid/$ID_FS_UUID
lrwxrwxrwx 1 root root 10 Aug 10 11:01 /dev/disk/by-uuid/4a6aed11-42dd-4c82-81ce-8f469e93f210 -> ../../sda1

Now we know the UUID and boot the system via root=UUID=… instead of a root=/dev/sda-entry:

title           Debian Etch, kernel 2.6.15-1-686 (on /dev/sda1)
root (hd0,0)
kernel /boot/vmlinuz-2.6.15-1-686 root=UUID=4a6aed11-42dd-4c82-81ce-8f469e93f210 ro
initrd /boot/initrd.img-2.6.15-1-686

Finally do not forget to adjust /etc/fstab as well for all entries:

UUID=e0164f78-9821-4eaf-bda7-1fd9b43a6f06 /     ext3  defaults,errors=remount-ro 0 1
UUID=4a6aed11-42dd-4c82-81ce-8f469e93f210 /home ext3 defaults 0 0

Understanding 32-bit IP

IP addresses are just 32-bit numbers. Subnet masks are just a "cover" that can be arbitrarily slid up and down the IP address's bits to create larger or smaller networks.

Focusing on 32-bit IPv4 addresses themselves now, there are a few different types that need to be understood. All IP addresses can be in the range 0.0.0.0 to 255.255.255.255, but some have special uses.

Loopback:
Packets that will not leave the host (i.e. they will not traverse an external network interface). Example: 127.0.0.1

Unicast:
Packets that are destined for a single IP address. Example: 2.2.2.2

Multicast:
Packets that will be duplicated by the router, and eventually routed by multicast routing mechanisms. Example: 226.0.0.2

Limited Broadcast:
A broadcast packet, sent to every host, limited to the local subnet. Example: 255.255.255.255

Directed Broadcast:
Packets that are routed to a specific subnet, and then broadcast. Example, assuming we are not on this subnet: 1.1.1.255

There are also some special cases of IP addresses, including private and multicast addresses. Addresses in the range 224.0.0.0 - 239.255.255.255 are reserved for multicast. Everything below that range is fair game on the Internet, excluding addresses reserved by RFC 1918 and a few other special-purpose assignments. These "1918 addresses" are private addresses, meaning Internet routers will not route them. The ranges include:

  • 10.0.0.0 -10.255.255.255
  • 172.16.0.0 - 172.31.255.255
  • 192.168.0.0 - 192.168.255.255

    These IP addresses can be assigned locally to as many computers as you want, but before those computers access the Internet, the addresses must be translated to a globally routable address. This is commonly done via Network Address Translation ( NAT ). The 1918 addresses aren't the only reserved spaces, but they are defined to be "site local." Multicast also has a reserved range of addresses that aren't designed to escape onto the Internet: 224.0.0.0 - 224.0.0.255 are multicast "link-local" addresses.

    Linux kernel 2.6.25

    From ** Linus Torvalds has annointed a blockbuster new kernel that required some 7.5 megabytes just for its changelog. The 2.6.25 release sets the stage for a war between ARM and x86 for the personal computing environment of the future, while also merging tons of improvements for real-time devices, desktops, and servers.
    • MEI/Panasonic MN10300/AM33 architecture support
    • Marvell Orion architecture support
    • A new interface for more accurate measurement of process memory usage
    • A 'memory resource controller' for controlling the memory usage of groups of processes
    • Realtime group scheduling
    • A tool for measuring high latencies called latencytop
    • ACPI thermal regulation
    • Timer event notifications through file descriptors
    • An alternative MAC security framework called SMACK
    • An ext4 update
    • BRK and PIE-executable address space randomization
    • RCU preemption support
    • FIFO spinlocks in x86
    • EFI support in x86-64
    • A new network protocol called CAN
    • Initial ATI r500 DRI/DRM support
    • Improved device support and many other small improvements
    Linux came to servers first. In
    1999, Linus said he wanted to win the desktop, but that embedded was
    the nearest land of opportunity for Linux. It took a few years, but
    today (and for the last two or three), Linux has been the top embedded
    OS in new project starts, according to many market research firms. So
    the desktop is next, right?

    Not exactly. A funny thing
    happened, on the way to the desktop. The desktop became embedded.
    Today, mainstream computing devices like the Asus EEE already have
    solid state disks, smaller form-factors, and other hallmarks of
    traditional "embedded" devices. There are even a few laptop-like
    devices showing up with ARM-based processors. Tomorrow, the personal
    computing device of choice may well be a pocketable iPhone-like device
    capable of plugging into any handy KVM (keyboard, mouse, and video
    display terminal).

    Original von Hanno Behrens

    »Darf man auf Windows denn Nicht-Microsoft-Schriften zu Word dazu installieren? Findet an dieser Stelle nicht die unlizensierte Nutzung der von Microsoft patentierten Systemschnittstellen statt, so dass man sich des Lizenzverstoßes schuldig macht?«
    Selbstverständlich darf man (sonst wäre manche Schriftenschmiede vermutlich längst pleite). Man muss natürlich drauf achten, entweder die Lizenz für die Schrift zu besitzen, oder nur freie Schriften zu nutzen. Das ist doch nun wirklich kein OS- oder Textproggispezifisches Prob.
    Du hast mit allergrößter Wahrscheinlichkeit recht. Die meisten Lizenzbestimmungen beziehen sich auf eine feste Verlinkung mit einer Bibliothek. Die DLL von Windows sind aber weich verlinkt, also verlinken zur Laufzeit, mit den Schriften ist es genauso.
    ABER das ist anders im zweiten Fall. Also wenn du ein Worddokument erstellst mit eingebundenen Schriften und mit PDF Dokumenten mit eingebundenen ist es genauso. Dann sind die Schriften ein Teil deines Dokumentes und an dieser Stelle wird die das Lizenzrecht wirksam.
    Soweit ich weiss, sind die Standardschriften von Microsoft, wie Garamond, Verdana, Arial und so weiter auch frei aus dem Netz zu beziehen und damit entschärft sich das Problem im Falle eines Falles.
    Sollte das Kopieren und Weiterreichen dieser Schriften jedoch nicht erlaubt sein, sondern die Lizenz sich allein auf den freien Erwerb und den Druck dieser Schriften beziehen, würde man sich dennoch strafbar machen, wenn man diese Schriften verwendet und mit ihnen erstellte Dokumente etwains Internet stellt.
    Und dann gibt es die zusätzlichen Schriften, die man bekommt, wenn man Office installiert und die man nicht frei aus dem Netz beziehen kann…
    Das hätte als Konsequenz, dass mit Word erstellte Dokumente nur weich mit den Schriften verlinkt werden dürfen, wenn man sie weitergibt. Was wiederum zur Folge hat, dass der Empfänger dieser Dokumente selbst diese Schriften installiert haben muss, um sie korrekt darzustellen. Im schlimmsten Fall heißt das, der Empfänger muss exakt die selbe
    Softwarekonfiguration und Version haben wie der Ersteller.
    Also kein Calibri auf Windows XP.

    Das hat natürlich direkt nichts zu tun mit der Frage Textverarbeitung oder Textsatz, aber indirekt schon. Denn bei LaTeX ist voreingestellt erstmal eine wirkliche freie Schrift, die alle Rechte der Nutzung beinhaltet. Die von mir verlinkten Schriften oben haben unterschiedliche Lizenzgrundlagen. Freie Schriften auf der einen Seite wie Libertine, DejaVu und ein paar hundert (nützlichen), die in Paketen mit jedem Linux ausgeliefert werden, dann die lizenzgebundenen, aber die frei heruntergeladen werden können und benutzt sprich gedruckt werden dürfen und schließlich die nur käuflich erwerbbaren Schriften, die garantiert nicht frei weitergegeben werden dürfen und damit in Onlinedokumenten nicht verwendet werden können ohne enorme Zusatzkosten zu verursachen,um die man sich dann kümmern muss.
    Wir leben nicht mehr in der Zeit des Ausdrucks. Da war das alles noch etwas einfacher. Also um den komplexen Sachverhalt zu verkürzen:
    Wenn du eine nicht freie Schrift in einem Onlinedokument verwendest und sie ins Netz stellst, dann stellst du praktisch die Schrift selbst zum freien Kopieren ins Netz. Und damit machst du dich eines klaren Lizenzvergehens schuldig. Wie sich das genau mit den Microsoft Schriften verhält, ist da wirklich zu klären! Denn die meisten Lizenzbestimmungen von nichtfreien Schriften beschränken das Nutzungsrecht auf den Druck.
    Warum gibt es wohl diese enorm aufwändigen freien Schriftprojekte, wo sich ganze Heere von Freiwilligen an das Erstellen von abertausenden Zeichen machen? Das machen die nicht, weil sie nichts besseres zu tun haben, sondern weil sie dazu gezwungen sind, wenn sie dieser Lizenzfalle entkommen wollen.

    Noch ein Fachforum mit dem selben Ergebnis
    und was Microsoft selbst dazu sagt
    Archiv der MS-Font EULA, bevor sie 'verschwunden' ist usw. usf.
    google-suche "lizenzrecht schriften" gibt fette Beute

    Ergebnis: 'Verdana', 'Georgia', 'Comic Sans MS', 'Microsoft Sans Serif', 'Nina', 'Tahoma', 'Wingdings', 'Webdings' and 'Trebuchet MS' dürfen 'Embedded' werden, aber nicht aus der Einbettung herausgenommen, Reverse Engineered oder anderweitig verwendet werden. Microsoft untersagt unter anderem explizit die Nutzung ihrer Fonts auf Linux-Oberflächen.
    Aber es gibt noch andere Einschränkungen, deren volle Absicht und Tragweite ich zur Zeit nicht abschätzen kann. Für das Web empfehle ich deshalb dringend die Vermeidung von Microsoft Fonts (auch wenn bislang gegen Niemanden rechtliche Schritte von Microsoft bekannt sind, kann das durchaus von fremden Parteien zum Anlass genommen werden - Stichwort Wettbewerbsrecht - gerade in Deutschland ist das Internetrecht leider sehr verbesserungswürdig). Ich selbst bin da kein Experte, aber Vorsicht kann nicht schaden.
    Jenseits der oben genannten Core-Fonts gelten diese 'weichen' Bestimmungen allerdings NICHT! Also Finger weg, wenn es im Web verwendet werden soll oder ihr vorhabt, die Dateien anderweitig digital weiterzugeben.
    Benutzt freie Schriften oder sogar OpenSource Schriften, das ist die Schlussfolgerung aus dieser Recherche. Mit LaTeX habt ihr da keine Probleme, mit Word könnte es kritisch werden, welche Schrift bei OpenOffice voreingestellt ist, das ist zu überprüfen. Das weiss ich nämlich nicht mehr, da ich bei mir sowieso alles auf OpenSource Schriften gestellt habe (weniger aus rechtlichen als mehr aus technischen Gründen).

    Linux vs. BSD

    what's the difference?

    Berkeley Software Division: FreeBSD- NetBSD- OpenBSD- DragonflyBSD

    • FreeBSD aims for high performance and ease of use by end users, and is a favourite of
      web content providers. It runs on a number of platforms, including i386 based systems
      (“PCs”), systems based on the AMD 64-bit processors, UltraSPARC® based systems, systems based on Compaq's Alpha
      processors and systems based around the NEC PC-98 specification. The FreeBSD project has
      significantly more users than the other projects.



    • NetBSD aims for maximum portability: “of course it runs NetBSD”. It runs
      on machines from palmtops to large servers, and has even been used on NASA space
      missions. It is a particularly good choice for running on old non-Intel hardware.



    • OpenBSD aims for security and code purity: it uses a combination of the open source
      concept and rigorous code reviews to create a system which is demonstrably correct,
      making it the choice of security-conscious organizations such as banks, stock exchanges
      and US Government departments. Like NetBSD, it runs on a number of platforms.



    • DragonFlyBSD aims for high performance and scalability under everything from a
      single-node UP system to a massively clustered system. DragonFlyBSD has several
      long-range technical goals, but focus lies on providing a SMP-capable infrastructure that
      is easy to understand, maintain and develop for.



    There are also two additional BSD UNIX operating
    systems which are not open source: XBSD/OS - Mac OSX

    Aussage eines Mediums

    "Das Internet wird kein Massenmedium, weil es in seiner Seele keines ist."

    DIE WELT, 24.03.2001

    IRC

    Internet Relay Chat DE, EN, ES

    IRC (Internet Relay Chat) es un protocolo
    de comunicación en tiempo real basado en texto, que permite debates en
    grupo o entre dos personas y que está clasificado dentro de la Mensajería instantánea. Las conversaciones se desarrollan en los llamados canales de IRC,
    designados por nombres que habitualmente comienzan con el carácter # o
    & (este último sólo es utilizado en canales locales del servidor).
    Es un sistema de charlas ampliamente utilizado por personas de todo el
    mundo.


    Los usuarios del IRC utilizan una aplicación cliente para conectarse con un servidor, en el que funciona una aplicación IRCd (IRC Daemon o servidor de IRC) que gestiona los canales y las conversaciones.


    IRC fue creado por Jarkko Oikarinen (alias "WiZ") en agosto de 1988 con el motivo de reemplazar al programa MUT (talk multiusuario) en un BBS llamado OuluBox en Finlandia. Oikarinen se inspiró en el Bitnet Relay Chat el cual operaba en la red Bitnet.

    IRC es un Protocolo de red que utiliza TCP así como opcionalmente SSL.
    Un servidor de IRC se puede conectar a otros servidores IRC para
    expandir la red IRC. Los usuarios acceden a las redes de IRC conectando
    un cliente a un servidor. Existen muchas implementaciones de clientes
    IRC así como de servidores. La mayoría de los servidores IRC no
    necesitan que los usuarios se registren, aunque de cualquier manera se
    necesita que los usuarios establezcan un alias antes de conectarse.


    IRC es un protocolo que envía sus mensajes en texto plano, lo que
    significa que es posible (aunque poco práctico) utilizar IRC mediante
    un cliente de flujo de bytes básico como netcat o telnet. De cualquier manera, el protocolo solamente utiliza una versión ligeramente modificada de ASCII,
    y originalmente no proporciona soporte para caracteres no ASCII en el
    texto, lo que da como resultado que existan muchas codificaciones
    incompatibles tales como ISO 8859-1, UTF-8, etc.


    Debido a que las implementaciones de IRC utilizan grafos acíclicos como su modelo de conexión, se carece de redundancia y por ese motivo la caída de algún servidor da como resultado un netsplit.

    "Usabilidad"

    Usability:
    Usability Basics: Introduction
    One of Aesop’s most famous fables is the story of The Lion and The Mouse. Written in the sixth century BCE and circulated across the globe, this story illustrates a point which has stood the test of time, and, which is often overlooked in Linux software developement. Examining this fable and its moral provides a starting point for understanding how usability testing can strengthen desktop Linux.

    The fable goes like this: A very small mouse, playing in the jungle, awakens a sleeping lion, who threatens to eat him. Bargaining for his life, the mouse promises to help the lion someday. The lion is so amused by this seemingly ridiculous promise that he lets the mouse go. (After all, what good could a tiny mouse possibly do for the king of beasts?) The next day, the lion is caught in a hunter’s net. He begins to cry, and the mouse hears his lament. The mouse runs to the lion, and nibbles through the net, saving him from the hunter. From then on, the two are close friends, who recognize the value of their extreme differences.

    The moral of this simple tale is clear: the differences in the individuals who inhabit our communities can be used to our advantage. The lion, for all his might, was unable to free himself from the hunter’s net; the mouse used his diminutive size to his advantage to crawl unseen along the net, dismantling it. Now what, you may ask, does this have to do with software?

    Traditionally, we tend to adhere to a relatively isolated development process. We may involve other hackers in the construction of our software, we may draw on the talents of GNOME artist to enrich our projects with beautiful icons, and we may even collaborate with translators to make our applications accessible to an international audience. But what about the people whom we interact with in our everyday lives? The experiences of our brothers and sisters, our friends and co-workers –the inhabitants of our home communities– are equally valuable in creating useful software. Usability testing provides the mechanism for processing their needs, and for cultivating better software.
