I’m currently building a website where you have an account and can do "dangerous" things with it. I want to password-protect these things, so the user has to type their password, if they want to continue. I couldn’t find any ressources on this, so I came up with this idea.
My method works this way:
- User navigates to dangerous action
- The server redirects the user to the password prompt website
- The user types the password
- The server checks if the typed in password matches the currently logged in user
- If check was successfull, the server redirects the user to the action with a uniquely created token associated to the user as a GET parameter
- The dangerous actions checks if the token matches to the user
- If match, the server will continue as normal
My question: Is this secure?
I think this is secure because I will probably make the token like 511 chars long and bruteforcing it would be very unlikely and I couldn’t find any other security holes in this.
Wall of Sand’s description reads as follows (emphasis mine):
You conjure up a wall of swirling sand on the ground at a point you can see within range. You can make the wall up to 30 feet long, 10 feet high, and 10 feet thick, and it vanishes when the spell ends. It blocks line of sight but not movement. A creature is blinded while in the wall’s space and must spend 3 feet of movement for every 1 foot it moves there.
To me, it’s unclear whether or not the bolded clause provides total cover to a creature behind the wall, or if the creature is simply heavily obscured. If you and another creature are on the opposite sides of a Wall of Sand, can you perform a ranged weapon or spell attack against the creature?
I’ve been getting advertisements from the Wall Street Journal Pro Cybersecurity.
I find this whole situation very bizarre, as I only know them as a business-focused newspaper. It seems they are releasing not only Cybersecurity news, but also Cybersecurity training?
Our news, commentary and training is designed to give senior executives the non-technical news and analysis they need
Apparently their training is:
Designed to help executives ensure that their businesses respond to cyber-attacks in a decisive and coordinated way, these tabletop exercises will allow you to identify gaps in your response plans and navigate challenges arising from security compromises.
Training packs are available for the following scenarios:
- Leaking Documents
- Historic Attacks
- Denial of Service
I must admit, the website does have a very “premium” look and color to it.
But my question is; is it common for news outlets to offer cybersecurity training? Is there any benefit choosing WSJ over a normal cybersecurity firm? (Is this a late April fools joke?)
The spell Wall of Bone details a number of statistics about the sections of wall created, including HP, but the description says nothing about AC. It is based on Wall of Stone but that spell does not mention AC either.
Did I miss some more generic rule about the AC of this sort of spell? Do attacks against the wall just always hit since it has no AC?
How do i solve this? I am not sure where to start.
If an enemy caster placed a Wall of Force between a Paladin and their ally, is the Paladin’s Aura of Protection inhibited while the Wall of Force is up?
The description for Wall of Force says that “Nothing can physically pass through the wall.” If that doesn’t include the Aura, is there anything that would inhibit it (lead, stone, etc)?
Purchased home and discovered one section of pipes which have been condensating for who knows how long, causing issues with the sheetrock. These pipes feed water to the washer/dryer. Plumber confirmed no leak, just condensation. Would we have to remove entire sections of wall just to add insulation to the entire length of the pipe? Not sure how long pipe goes on for. Any suggestions or advice? Thanks! Thanks for the advice; I’ll be contacting home warranty to get another plumber to rule out any underlying issues.
Wall of fire has to be cast on a solid surface. What’s a solid surface? Can it be the back of a dragon? Dragon scales are pretty solid..
If the solid surface disappears (ice melts away, roof collapses) does the spell then fail or stay where it was cast for the duration?
Consider a problem where a “robot cleaner” is placed on a room modeled as a grid. Each cell in the grid can be empty or blocked and all accessible cells are connected, meaning, all empty cells will be accessible by the robot regardless of its starting position.
We are told that the robot cleaner can only take one of four actions:
- move forward
- turn left (90 degrees, without moving)
- turn right (90 degrees, without moving)
- clean the current cell in the grid
We are asked to design an algorithm for the robot to clean the entire room.
My question is: Can this problem be framed as a maze solving problem? I mention this because a common strategy (if the maze is simply connected) for maze solving is to be a “wall follower” (e.g. always try right, or always try left), and I wonder if wall following would work here.
More generally, why would “wall following” be a good strategy for either problem? Isn’t it enough to do DFS (with backtracking) even if we pick an arbitrary order of directions that are “left to explore” from each grid position? (or explore directions at a given position in any order?)
The situation I am wondering about is if Wall of Fire is cast upon a wall and then the wall either falls over or crumbles. Would the wall of fire remain floating in the air? Would it disappear? Would it follow the surface to the ground?
Wall of Fire reads:
You create a wall of fire on a solid surface within range.
