Para memorias USB, FAT32 está bien porque el medio tiene tamaños

más conveniente, y no sólo por las limitaciones técnicas que tiene y que 
acabas de padecer (tamaño máximos de los archivos y particiones, número 
de subdirectorios, no admite cifrado, etc...) sino porque te arriesgas a 
pérdidas de datos si se trata de un volumen que montas y desmontas al

Si no necesitas compatibilidad con sistemas Windows, o puedes acceder 
al medio desde la red donde el sistema de archivos del anfitrión es 
indiferente para el cliente invitado, XFS se recomienda para archivos 
gordos. Ext4 también es una buena opción.

Si necesitas acceder a esos datos directamente desde un sistema Windows 
(p. ej. si tienes instalado Windows y Linux en el mismo equipo), 
entonces NTFS no sería mala opción. Eso sí, en este caso formatea el 
disco desde Windows, mejor.

 En principio NO uses la FALACIA de desplazamiento para sustentar una idea 
falsa.
Lo cual quiere decir que NO pongas la culpa en quien padece, acusando de la 
forma "ahora que a ti no te funcione o no quiere decir" lo cual es FALSO.
Usando esa FALACIA que usas yo también podría decir ésto: "Ahora si vos te 
conforma usar basuras no quiere decir que nosotros debamos usar las basuras que 
tu usas" ¡Esa es la fórmula falaz que TU usas!

De los sistemas que indicas sólo Cinelerra-GG y Kdenlive son editores 
SEMI-profesionales de video con GRANDES PROBLEMAS de soporte y desarrollo. 
Cinelerra además es inestable.
Cuando se edita video en forma PROFESIONAL se necesita COMPATIBILIDAD, 
ESTABILIDAD y RAPIDEZ y un gran universo de ad-ons que en Cinelerra-GG y 
Kdenlive NO existen. Por otra parte tanto Cinelerra-GG como Kdenlive son 
lentísimos al renderizar. En cambio Vegas Movie Studio no sólo es más rápido en 
renderizar sino que además el proceso de renderizado puede hacerlo en forma 
simultánea en varias máquinas conectadas en red por lo que el tiempo se acorta 
muchísimo. Esto NO se puede hacer con ningún editor bajo Linux. También está el 
Adobe Premiere Pro con miles de efectos preinstalados los cuales NO existen en 
NINGÚN editor para Linux

Y hablando de FreeCAD... si haces un plano de un edificio y lo llevas a que te 
lo aprueben en el municipio... TE LO TIRAN POR LA CABEZA... Así de simple... 

Mira... trabajé en sistemas desde 1974 (empece con UNIX), ahora tengo dos 
empresas (nada que ver con sistemas) una de edicion de video y otra bursátil... 
lo mío es buscar lo eficiente (más resultados con menos recursos) así que NO me 
quiero romper la cabeza por ahorrarme dos pesos y tampoco quiero que algo NO se 
haga porque en Linux NO se puede hacer. Linux es bueno para muchas cosas pero 
para edicion de video le falta MUCHO, pero mucho mucho. Ya probamos todo editor 
bajo Linux que se nos ha cruzado y todos ellos están muy por debajo de Sony 
Vegas y de Adobe Premiere. Y... para transcodificación NO hay nada mejor que el 
Format Factory que trabaja en Windows... en Linux NO hay cosa que siquiera se

You're not wrong, in the sense that that covers a wide variety of use
cases. There remains a niche for rich desktop GUIs that 1) can display
remotely, 2) execute sandboxed code on the display server, and 3) play nice
with a windowing system rather than being just a "page". I wouldn't be
unhappy with that sandboxed code being JavaScript (or even WASM). I would
be unhappy with every GUI app I use running a web server and launching a
browser to http://localhost:/

Incorrect password Debian 10.8 after installation

[John Berden]

Hello.
I'm installing Debian 10.8 with a console installer. I use ISO 
debian-10.8.0-amd64-netinst.iso.

After starting the system, I get a request for the user's password.
I enter the correct password that I specified during installation. But I 
get a message that I entered the wrong password.

Why and how to fix it?
Thanks in advance!

You have reinvented NeWS with Display PostScript
. Don't get me wrong, it was a great
idea, ahead of its time, and not especially well (or efficiently)
implemented at the time, so it may well be ripe for reinvention. Given that
we have much better facilities for sandboxing and hardware accelerated
graphics than we did at the time, now might be the time.

Re: Linux router AP with reserved IPs on wlan0?

[Gregory Seidman]

If you want a Linux router/AP, I recommend OpenWRT over Debian. It runs on
a variety of router hardware, but also PCs: 
https://openwrt.org/docs/guide-user/installation/openwrt_x86

Importantly, it uses UCI
 for configuration of
switches, networks, 802.11 (wifi) radios, SSIDs, firewalls, etc. which
substantially simplifies handling the issues you are encountering. Its web
interface (luci) works directly with the UCI config files, so it's easy to
switch between editing a file and working in the web UI.

Strange statistics from gparted

[Richard Owlett]

I am experimenting with custom installs of MATE on Debian 10.7 .
My goal is to minimize its footprint on disk, and reduce menu clutter.
I have a default install with / on sda1.
The custom install has / on sda2.
Both installs use /sda3 for /home.

When running gparted from the first, it reports
  sda1 used space is 3.85 GB
  sda2 used space is 2.25 GB

When running gparted from the second, it reports
  sda1 used space is 4.77 GB
  sda2 used space is 1.80 GB

Why?

I have several multiboot systems with RAID. I simply copy /etc/mdadm.conf from 
the
original Linux installation to each additional Linux installation, and ensure
mdadm is installed, which means I copied from older installation to newer. 
Whether
anything about RAID configuration changed between Stretch and Buster that would
prevent the newer from working with the older I have no idea.

I think this is the correct answer.

The mdadm.conf file can also be copied over from buster.

Stretch and Buster are on the same machine.
I was hoping to be able to mount the raid configured on Buster from
Stretch, with something like:

$ mount /dev/md0 md0
mount: special device /dev/md0 does not exist


The same command works fine on Buster, Mdadm is not installed on Stretch.

Probably you haven't installed "mdadm" package on Stretch.
Also it is generally a good idea to create a configuration file 
"/etc/mdadm/mdadm.conf" [1] on Stretch.
You can use this command to create array configuration string from 
metadata on disks:

# mdadm --examine --scan

To check array status:
# mdadm --detail /dev/md0



[1] $ man 5 mdadm.conf

That should work out of the box. Have you tried it and it didn't work?

The RAID is on the same system. They clearly wrote "multiboot".

Accessing raid from multiple hosts

[john doe]

Debians,

I have a multiboot system (Buster and Stretch),, the raid was configured
on Buster and works well.

now, I need to access that same raid from Stretch.

Has anyone been able to access a raid from multiple hosts, if yes, how
did you do it?

Jus thinking - Low level X GUI with shaders

[Marek Mosiewicz]

Hi,

I would like to share my thoughts considering remote appliation
problem.

In beginnig there was X server :) It was designed in mind to enable
using of applications in distributed environment. You could open window
which was just running on other computer.

Time passed and things changed. There is attitiude to use Wayland for
Unix GUI which is fast versitile and easy, but not remote.

On other side remote apps tend to be run in browser, which is nightmare
for developer.

X server demise is caused, by difficult problem it tries to solve.
Abstracting GUI toolit protocool is painful. 

But I just look into idea that you do not need to do so. I think it
could be possible to pass shader program to X server (even as string).
This shader program could be whole GUI lib. It could manage theme,
layouts, fonts, widgets, data model on its own on x server. It would
depend on widget system how exchange data between client and server.

There are already similar solutions done in browser by libs like Apache
Wicket, ZKOSS and others. They act for user input, send it to server
and server sends updates client. However client state (or rather X
server) is rich and you update it by widget properties so communication
is really efficient.

Hi Tixy.

For the archives, the documentation to configuration of dnsmasq(1) is
in /etc/dnsmasq.conf, the dnsmasq configuration file. It is verbose,
and there are many options. Read thoroughly.

It is a very impressive accomplishment, and works well, and is fairly
easy to get working, (once familiar with the configuration file.)

As a closing note, the DHCP/DNS services, (for wlan0,) are configured
in the /etc/dnsmasq.conf file, *_NOT_* /etc/dhcpcd.conf, which is the
usual alternative.

(This is where I went astray-I mean the name is dnsmasq, probably
meaning it is something to do with dns, duh.)

Thanks to all,

John

I didn't know about /etc/ethers, on my system I allocate fixed IP
addresses and hostnames by adding a lines to dnsmasq.conf like

dhcp-host=MAC-Address,IP-Address,Hostname,Lease-Time

I guess there's more than one way to skin this cat.
