container – Podman: What if user is member of docker group?

From a security perspective: Is it necessary that a user, that runs OCI containers with Podman, is not at the same time a member of the docker group?

From what I understand the idea behind Podman is to re-map the user ids, such that the root user within the container is equivalent to the user on the host. The security concept is better because if a user can take over the container and break out, the user is not automatically root user on the host (given that the process within the container was started as the container’s root user).

Now if the user on the host is in the docker group it should be equivalent of having root access as stated in the Docker post-installation guide:

The docker group grants privileges equivalent to the root user. For details on how this impacts security in your system, see Docker Daemon Attack Surface.

So if an attacker breaks out of a container managed by Podman, and at the same time the user who started the container is in the docker group, the security gain should be none compared to managing containers with Docker. Is this correct?

r – How to break ties in sorted data by a function of a group of columns?


> output<-cbind(matrix(sample(15,replace = TRUE),nrow=5,ncol=3),c(sample(5,replace = TRUE)+20),c(sample(5,replace = TRUE)+15))
> output
     (,1) (,2) (,3) (,4) (,5)
(1,)    6   11    9   21   16
(2,)    4   11    3   24   16
(3,)    2    8    3   24   17
(4,)    9   11    1   22   18
(5,)    5    3    3   24   19

Now suppose that I want to sort this by column 4, breaking ties by column 5. With order and a little help from Stack Overflow, this is not much of a challenge:

> output(order(output(,4),output(,5)),)
     (,1) (,2) (,3) (,4) (,5)
(1,)    6   11    9   21   16
(2,)    9   11    1   22   18
(3,)    4   11    3   24   16
(4,)    2    8    3   24   17
(5,)    5    3    3   24   19

My question is in a final requirement: What do I do if I want to sort my data further, by a function of any tied rows’ entry in columns 1, 2 and 3? For example, how could I achieve the sort: “Sort by column 4 in increasing order. If there’s a tie, sort by column 5 in increasing order. If there’s also a tie in that, put the row with the lowest value in all of columns 1, 2, and 3 first (i.e. sort by min(col 1, col 2, col 3))“? – Mainly target on Asian Countries Group – UPDATE 04/06/2020

dnd 5e – How can a group find out how to break Imprisonment?

There is the Identify spell which you can use to find out what spells are affecting an item or a creature, or if it is a magic item what kind of magic item it is or how to use it.

In this specific case however, the more appropriate spell would be Legend Lore, which can give you information about things of “legendary” importance; What is and isn’t legendary isn’t defined anywhere so it’s ultimately up to the DM, but if a dragon kidnapping a princess, and a hero coming to her rescue and defeating the monster isn’t legendary then I don’t know what would be.

Note that the Imprisonment spell prevents divination magic from “locating or perceiving the target”. This quite clearly prevents spells such as Scrying or Locate Creature from working; however it is less clear what the effects of Identify and Legend Lore would be; They are both Divination spells, but neither does actually have anything to do with “locating” or “perceiving” the imprisoned creature. The spell doesn’t prevent Divination spells from targeting the creature after all, as for example the Nondetection spell would. Legend Lore presumably couldn’t tell you where the creature is imprisoned as that is arguably locating it, but nothing about Imprisonment would prevent you from learning the way to free the imprisoned creature.

Aside from magic, it is entirely up to the specific situation. Perhaps the Hero in question kept a diary. Maybe it is a story told to children by this point and thus actually public knowledge. Maybe a creature who was witness to the event is still alive and you can interrogate her.

group dynamics – I don’t like a fellow player, what should I do?

We’re playing online.

I don’t like the player, not the PC, the PC themselves is fine, which kinda makes this worse, if it was the PC, I could chalk it up to good RP.

This player also isn’t unlikable/overtly terrible like in rpghorrorstories where I can call them out that what they’re doing is wrong or something. They just make annoying jokes a lot of the time, making fun of everything happening in game (though tbf and respectfully, their own character is also the butt of the joke sometimes) and are weirdly specieist to certain things in D&D (mostly to monstrous races believing all of them to be evil), not the PC is specieist, the player. (and the DM has established that as objectively not true in this campaign world)

I think this is mostly a difference of opinion rather than outright them being a bad player (though I certainly think so, since I’m biased)

The campaign is reaching a point where I and my character could leave without causing a problem (i.e. not during combat and stuff), so I’ve been thinking of just leaving, though I’ve also thought of telling the DM that I won’t leave if the other player is kicked out, but I don’t want to pseudo-blackmail my DM. I also don’t think talking would just solve this (we’ve already tried talking with them about the specieist point, and they haven’t changed, and I think I’m really the only one that finds their jokes annoying)

I think the best thing that would happen is if they leave of their own volition, which I don’t want to instigate by antagonizing the character in game and stuff because I don’t want to be a terrible person/player, and ruin everyone’s fun

Create a Group in a Modern site and manage file’s permissions

I have some folders and documents and I need to give them different permissions to the people who aren’t owners of the site.
I need to create some groups of people, so that they can only be seen for those who are part of a certain group.

But I can’t find how to manage groups in the modern sites. When I click the “Members button” (picture below), it only has the option to add members and change their group. I want to know where I can change the permissions of groups, create and delete groups, etc..

database – Organizing Data with Specific Group in Objects and Lists

So recently I have been working with a large-scale app that has a large number of individual objects with specific group attributes. For example, I have a list with objects such as

{Name: "Todd", Desc: "Todd likes basketball", Team: "#23"}

This list is has about 10k of these objects in it with about 1,000 different obj.Team values, ranging from Team: #1 -> Team: #1000.Throughout my app, I will be using the full list of objects for certain calculations as well as just viewing all objects with a certain obj.Team value.

I will be using a Redux State w/ React to store these values and I was wondering what the best method would be in terms of performance, better practice, readability, etc. Would it be preferably to have two lists where one list is the full 10k objects while another list is a list of lists based on the Team value, where the same obj data is copied to two lists (with just different format)? Or would it be best to simply have a single list of these 10k objects and when I want to use some calculation on a specific obj.Team value, I just loop through and find the appropriate objects?
