How can I create a Windows bootable USB stick using Ubuntu?
Recommendations on a free library to be used for zipping files I need to zip and password-protect a file. Is there a good (free) library for this?  This needs to be opened by a third party, so the password protection needs to work with standard tools. How to find relevant and new open research topics? How can one find relevant and new open research topics?  When working on my PhD thesis, I find it hard to find open questions in my very specific research area. Which approach do you take to find new and relevant topics? Or "Why is Ant-Man the last movie of Phase 2, rather than Avengers 2?"  The Marvel Cinematic Universe is the series of movies involving characters from Marvel comics and produced by Marvel Studio/Disney Studio. The series of movies is decomposed into phases, that are different steps in the studios' production plan.   Phase 1, entitled Avengers Assembled, is composed of all movies from Iron Man (2008) to The Avengers (2012). This phase relates the origins of each Avenger and how these mighty superheroes came to fight as a team.   The narrative purpose of Phase 2 is less clear to me. At first, I thought it was about Thanos' story arc but Thanos doesn't seem to appear in Ant-Man, the last movie of the Phase 2. Actually, Thanos will most likely be the main antagonist of Infinity War, which is a part of Phase 3.   Therefore, what story arc will be concluded at the end of Ant-Man? I believe it can be answered before the movie is released, as the purpose of Phase 1 was clear before the release of The Avengers. Marvel Studio may also have commented about the organization of the movies. In other words, what narrative elements unify the movie of Phase 2? MySQL Seems to be crashing quite often, I'd say every hour or so.   The only thing running on this server that is using MySQL is a Drupal installation that I'm working on, there's only one person that's using it and it literally has around three pages - from what I can gather this seems to be a memory issue with innoDB? I'm not great at this stuff so I'm unsure.  Any guidance?

This particular Droplet is running NodeJS, MySQL and Apache. There's a low-traffic static site, a Ghost blog and this Drupal site I'm developing.   Should I just upgrade the RAM, or is there something I can do to fix this? Is it possible to query the content of the Time-based Workflow Queue from an Apex unit test to assess that a specific Workflow Rule has been executed and added a new item to the queue? I didn't see anything alike in the documentation, but wish it could be possible to improve testing and stability overtime.  Thanks What's the term in music, where the singer uses words without meaning? I've been searching for the word, which is used for describing parts of lyrics, where the singer sings for example the whole refrain only using words of syllables without any meaning. Maybe you could help? (here's one song with that type of refrain: ) How do I space quads evenly? Is there a way in blender or an addon that allows me to select a bunch of faces (or verts) and evenly distributes (or relaxes) them into quads clean quads.  Without screwing up the vert ID/order.  Edit: I would like to have the shapes of my quads to turn into perfect squares while maintaining the volume of the object and the vertex order. How to test whether a file uses CRLF or LF without modifying it? I need to periodically run a command that ensures that some text files are kept in Linux mode. Unfortunately dos2unix always modifies the file, which would mess file's and folder's timestamps and cause unnecessary writes.   The script I write is in Bash, so  I'd prefer answers based on Bash. I am trying to run the following model:         I(week^2):mutation_status +         (week + I(week^2) | subject_id) ,          data = sim_dat)  This is the output I get from this model. The correlation between week and I(week)^2 is rather high (-0.95) and I was curious to know how I can change my data simulation code to lower that value. I am also having issues with convergence and would love to get thoughts on how to avoid issues regarding convergence. Thank you!

I have a configuration file where a developer can specify a text color by passing in a string:   &lt;text value="Hello, World" color="Red"/&gt;   Rather than have a gigantic switch statement look for all of the possible colors, it'd be nice to just use the properties in the class System.Drawing.Brushes instead so internally I can say something like:   Brush color = Brushes.Black;   // Default   // later on...  this.color = (Brush)Enum.Parse(typeof(Brush), prasedValue("color"));   Except that the values in Brush/Brushes aren't enums.  So Enum.Parse gives me no joy.  Suggestions? Intuitive explanation of binomial coefficient formula Regarding the formula for binomial coefficients:  $$\binom{n}{k}=\frac{n(n-1)(n-2)\cdots(n-k+1)}{k!}$$  the professor described the formula as first choosing the $k$ objects from a group of $n$, where order matters, and then dividing by $k!$ to adjust for overcounting.  I understand the reasoning behind the numerator but don't understand why dividing by $k!$ is what's needed to adjust for overcounting. Can someone please help me understand how one arrives at $k!$? Thanks. $t^3$ is never equal to Let $t$ be a real number such that $t^2=at+b$ for some positive integers $a$ and $b$. Then for any choice of positive integers $a$ and $b$, $t^3$ is never equal to: (A). $4t+3$ (B). $8t+5$ (C). $10t+3$ (D). $6t+5$  We have $t^3 = at^2+bt$ and so for (A) we have $t^3 = 4t+3 = 4(at^2+bt)+3$. I don't see how to continue since this is a cubic equation. Is there an easier way of finding a contradiction?
