I reset my Chrome browser, now I lost all logins, how do I get them again? Facebook, youtube, reddit, quora, etc... all are signed out.  I have another PC which hasn't synced using Internet (still not connected), can I use that to get logins again?  I can manage with some websites, but I'm afraid I would need logins for websites which I have forgot the password of.
Google Chrome: Import/Export Passwords? I recently migrated from Windows7 to Kubuntu 10.0.4. In many ways, I'm loving the change. (I never knew it could be such a seemless process to write/test scripts!)  One of the few things that is causing me any hangup is that none of the passwords that were saved in my browser are available (obviously, since it's a completely separate installation). Is it possible to export my passwords from the Windows instance of Chrome and then import them into the Linux version?
I am drawing some graphs with tangents. I calculated the tangent should be centered at x=57/27 which is approximately x=2.11. I'm currently using the pos and sloped keys for nodes to draw tangents, but I'm not happy about the result; the tangents don't really align.   I think this is because the pos key calculates the actual length of the graph while the graphs don't have the same length.  I'm sure I can somehow let LaTeX do the calculations for me so as to align the slopes vertically at an x value of my choice. But how?

Science fiction story where a colonist is sent by a company to colonize a planet and there a robot tries to sell him a depilating liquid by pulling a gun on him. The company who sponsored his trip to the new planet is extorting him by charging him exorbitant rates for anything they declare is not considered by them as bare necessities. The robot and man collaborate to get from the company the fair deal he deserves. I am using QGIS 3.2.0 on a Mac (and also have QGIS 2), and I have a fishnet grid (probably created in Arc) that comprises of nearly 2 million grid cells. As a result, every change I make to the attribute table takes hours, so I can't experiment as I would usually.  I need to label each grid cell such that the north-westernmost cell is "1", and the numbers proceed by rows, until the last number goes into the south-easternmost cell. Using the row-number doesn't work, as that's not how the table is sorted. I've done this before, but cannot remember how. Script to Notify me when something happens on a shared directory The situation is:  I have a shared directories from many other machines where other users work on.  I need to be notified whenever a user create, modify or delete a directory or file from his local directory which I share using smb...  It looks like the folder actions in the MAC systems..  Is there a software that do that?!  If there is no such application, any help in writing a script for that is appreciated..  Thanks in advanced... The representative point of a cluster or cluster center for the k-means algorithm is the component-wise mean of the points in its cluster. The mean is chosen because it helps to minimize the within cluster variances (which is to say that it is minimizing within cluster squared Euclidean distance, since its the same). Now, when I want to use a different distance metric, like L1 (Manhattan distance), I would be minimizing the within cluster absolute deviations (if I choose to). I was looking at what the centers calculation would be like, because the mean won't reduce the new objective function, and I found this on the Matlab documentation of their kmeans function for the distance parameter     cityblock - Sum of absolute differences, i.e., the L1 distance. Each centroid is the component-wise median of the points in that cluster.   Now, how did they come up with the component-wise median? How does a median minimize absolute deviations?

When and how did "pretty" enter English as an intensifying adverb? Today I saw an idiomatic road sign: "Pretty Muddy". I found this lack of strict English on a road sign unusual (on par with my "Dead Slow" official speed limit sign in Leeds, pic below), but as it turned out it's a charity race and the signs were merely directions.  This got me thinking however, how do words like "pretty" and "dead" as   end up in English? Taking "pretty" as an example, when did this first appear?     I wonder how fast you have to be going before they stop you. How would this hold up in court? Can we use sine and cosine graphs for varying temperatures? I have been researching for a while looking for what to include more than just deriving the equation of Newton’s law of cooling and a website gave me inspiration by stating what if the temperature of the environment is changing (± C). In conclusion, I wasn’t sure if that person carried out the mathematical process in the right way and the only place I could ask for accurate information is here so please let me know what you think about the mathematical process he went for and if it is right or wrong. Thanks a lot. Website: In propositional logic, the statement "If pigs can fly, then elephants can lay eggs." validates to true because the antecedent validates to false.  In other words, given $a \rightarrow b$, if a is false, the entire statement is true. Why?  Just because the antecendent is false doesn't mean that another fact depends on it, right? Can any one help me with this?  Determine all integer triples $(x,y,z)$ such that $1 ≤ x ≤ y ≤ z$ and $x + y + z + xy + yz + xz = xyz − 1$.

Function overloading in C Currently, when someone suggests an edit, they are unable to keep track of it without watching reputation levels or constantly refreshing the page. What I would like is a notification, that shows up like the notification where someone has edited your question, that shows whether a suggested edit has been approved or rejected after the last vote is cast. This way, the community can be notified when their edit has been rejected/approved, while focusing their efforts on another question/answer. According to      there         adverb          in or at that place (opposed to here ):      She is there now.         pronoun          (used to introduce a sentence or clause in which the verb comes before its subject or has no complement):      There is no hope.   Then, what element is there in:     There is the man.   I'm confused because "There is the man" is an adverb inversion, in which there is an adverb and "the man is" is inverted. But according to the definition above, there suddenly becomes a pronoun.
