Re: Zoom en Debían 11

2023-06-25 Thread Carlos Villiere
Hola lista!!
Probé  el Zoom en mi plataforma educativa y el problema persiste.
Lo extraño es que puedo bajar los archivos (de tipo .zip) desde el cliente
de Zoom en un móvil Android (Samsung Galaxy j5) sin problemas, aunque
aparecen caracteres aleatorios delante el nombre del archivo como por
ejemplo "ea2f -fd3ab...etc. , lo que hace suponer que en vez de subir el
archivo lo están copiando y pegando en el chat, la mayoría usa Windows.
¿Podria ser el problema? En el chat parece que estuviese pintado, la opción
de download no funciona, pero si me permite subir archivos, ya que intente
y la opción funcionó aunque no complete la opción
Desde ya gracias
Abrazo

It depends, but possibly you could just add calls to your "simple
script" on the ExecStart= and ExecStop= lines of the nftables
service. It's a list of commands with semicolons as separators.

I think those are a little more complicated than it seems on the
surface. Obvious point being, Before= and After= are ordering
constraints, Requires= is not.

Linux's firewall is designed so that it can be configured before the
interfaces are up, or even exist. Without that, there would be a short
time with the interface up but no firewall.

I think most of the time, this is not done as a systemd service at
all.  It's usually invoked from the "up" hook when your network interface
is brought up, assuming you use /etc/network/interfaces.  If you use
NetworkManager, then I don't know.

How to create a systemd service that interact with nftables service

Hello, all.

I have a simple script, to save / and store dynamic nftables sets.

I would like to create a systemd service, that starts -after- nftables is

Rappel: RAID, je n'y connais rien, jamais utilisé, jamais configuré

Comme Hughes le dit, sous Debian (je ne sais pas sous d'autres 
distributions comment c'est géré), la manière habituelle de gérer le 
Fakeraid (les cartes RAID logicielles (via l'UEFI/BIOS), pas les vraies 
cartes RAID matérielles (un peu la même distinction qu'il y a 20 ans les 
winmodems et les vrais modems matériels)  c'est via dmraid, pas via mdadm.


Ceci dit, il semblerait qu'on puisse forcer l'emploi de mdadm même pour 
du Fakeraid (au lieu de son emploi habituel pour du raid strictement 
logiciel au niveau de l'OS Linux):

https://wiki.debian.org/DebianInstaller/SataRaid

pour l'utilisation de mdadm (que je ne maîtrise pas), je te renvoie vers

connecte ton smartphone à ton PC via USB, il y a une notification dans 
la barre des tâches Android informant que l'appareil est en charge: 
clique dessus et tu te vois offrir un menu au sujet:
- du directeur de la liaison: le PC dirige ou le smartphone dirige (ce

- du type de liaison: charge ou transfert (avec choix du sous-type de

donc dans ce menu, je pense que si tu veux que le PC puisse forcer la

Well no I didn't know that. I don't have a modern day UEFI. But I
concluded that there is some control of the fan from the fact that
Windows 10 does it, and that the fan speed is lower in the winter even
with Debian. But I suppose that could be the BIOS.

Some examples from doing stats on text are: average word
lenght, most commonly used words, the longest paragraphs ...

Those are simple examples, the next step it gets more
interesting as it could show what is statistically unusual,
that would be fun/exotic stats that a human user would
probably not spot.

E.g., parsing this mail, it could say "Emanuel Berg is almost
always calm and collective, entirely professional in his
approach, but here in the 4th paragraph of his mail he gets
VISIBLY UPSET using CAPS ONLY, possibly expressing FRUSTRATION
about NOT BEING UNDERSTOOD."

In the sports world they input the stats manually and that
data is then crunched by computers to produce lists and neat
graphics for their broadcasts. This is the first step
described above. This isn't unlike for example Emacs
`count-words-region' in combination with gnuplot - indeed, it
is exactly the same, almost, as these chars I type now are
produced manually, then Emacs could count and gnuplot
could show.

This first step would be neat depending on how much stuff is
quantified, the more the better obviously.

The second step however, that would be those "fun facts" the
commentators say, these are more advanced, like, and now
I just make something up, "Here is an amazing figure.
Player X has the worst stats on face-offs in his team, except
when the team plays on its home field and is down by two or
more goals, then he is 2nd best".

That second step, to have with text, would of course be even
more exciting.

I don't know if those crazy stats are discovered by a bunch of
fanatic hockey nerds just using the "step 1 stats" in creative
combinations - maybe using some sort of relational algebra
approach? - _or_ if they have some stats engine that crunches
the stats further to the meta-stats level, if you will, to
have the weird facts pop up automatically?

But yeah, if we don't even have a proper "step 1 stats" tool
for text - which is impossible to believe BTW - well,
obviously one can only dream of a "step 2 stats", a stats tool
on the meta level ...

It is not about understanding, it is about finding patterns
and meta-patterns, finding statistics that are themselves
statistically uncommon, which is why they are interesting.
Think exceptions and unexpected interrelations. Again, the
best example is probably a combination of the different stats
available at the "step 1 stats" level.

Yeah, maybe I should ask them but as Debian is such a huge
system one would think someone here could show us how it, or
similar software can be used on a bunch of text, for
example on a mail like this.

It is already a bunch of data, surely you are not saying there
isn't a tool to tell us something of that data?
