Do we get same regular expressions at the end regardless of the order that we take the states step by step? Can somebody prove by exemplification?
Is it possible to use any automated scanning tool in order to detect stored passwords in our internal wiki pages?
Some websites make it easy to enrol multiple TOTP apps at the same time but make it difficult to disable these apps. For instance, the user would have to completely reset the MFA settings instead of just disabling one TOTP app, or the user would have to provide a state-issued ID to have this done by user support.
What type of threat scenario does this address? After all, an attacker who would be able to authenticate as a legitimate user would then be able to change the password and lock the legitimate user out, so what is the difference?
I’m trying to find a list of the used TLS libraries by the different browsers. I made a search and I didn’t find such a list. Can anyone help me?
I am trying to understand the difference of assignment, binding, and substitution. I know the three things are related, but to me it’s not exactly clear what word refers to what. Example, illustration, and citations from computer science wiki/articles/textbooks are welcome.
The question is inspired by the following UVa problem: https://onlinejudge.org/index.php?option=onlinejudge&Itemid=99999999&category=18&page=show_problem&problem=1628.
A network of autonomous, battery-powered, data acquisition stations has been installed to monitor the climate in the region of Amazon. An order-dispatch station can initiate transmission of instructions to the control stations so that they change their current parameters. To avoid overloading the battery, each station (including the order-dispatch station) can only transmit to two other stations. The destinataries of a station are the two closest stations. In case of draw, the first criterion is to chose the westernmost (leftmost on the map), and the second criterion is to chose the southernmost (lowest on the map). You are commissioned by Amazon State Government to write a program that decides if, given the localization of each station, messages can reach all stations.
The naive algorithm of course would build a graph with stations as vertices and calculate the edges from a given vertex by searching through all other vertices for the closest two. Then, we could simply run DFS/BFS. Of course, this takes $ O(V^2)$ time to construct the graph (which does pass the test cases). My question, though, is if we can build the graph any faster with an appropriate data structure. Specifically, given an arbitrary query point $ p$ and a given set of points $ S$ , can we organize the points in $ S$ in such a way that we can quickly find the two closest points in $ S$ to $ p$ (say, in $ \log V$ time?).
Resolved as in, in the past… Are there any tools for this?
I am doing some research into pentesting and subdomain takeovers with cloud providers like AWS and Azure. I have a list of subdomains (A records) that could be used for this, but they are indecipherable in terms of seeing where they once resolved to. Without this information, the entire thing is redundant.
For example: sjd-3949-af3.trafficmanager.net would have originally resolved to mydomain.takeover.com but doesn’t now.
Anyone know how to find this out please?
I have a deep understanding of the P vs NP question, and how unlikely they are. However, i want to know if they are, what computational problems(np-problems) can help develop a vaccine (i.e. for covid19).
Any resources please? Thank you.
