I have a lot of volumes (folders) mounted from remote machines, about 10 of them, which I set to be mounted automatically when I'm logging in by adding them to the Login Items list in Users &amp; Groups. Of course, I made sure to tick the Hide check box of each of the volumes, yet OS X opens each of the folders whenever I log in so I have to close them one by one manually.  When an application starts, the hide button makes sure no windows are drawn visibly. Can Finder be configured to respect the "hide" flag similarly?
I have some shares that are mounted during login. I used Users &amp; Groups' "Login Items" panel to do this. When I login, all of the shares pop up in their own Finder windows.  How can I keep the Finder windows from popping up at login? I've already tried checking the Hide checkbox.
Can I put a metal safe weighing 2000 lbs in a 12x12 room? I have a 12'x12' upstairs bedroom. Can a 2000 lbs safe be placed in that room? The dimensions would be the same size as a queen size bed (60"x80").  Can you supply the math in your answer.  Thank you in advance  Danny How to preserve bookmarks when rearranging pages of a PDF file with tools like pdftk? I am using pdftk to rearrange pages of a pdf file with bookmarks/outlines, but after that, the output file lost the bookmarks of the original.   My command is pdftk in.pdf cat 1-22 43 23-42 44-end output out.pdf.  I was wondering how I could keep the bookmarks while rearranging pages? Putting altered social media logo icons on my website, can I get sued? I would say most websites with a somewhat thought-through graphical design use social media icons (i.e Twitter, Facebook, YouTube, etc) which are altered to fit the theme and design of the site.  Now, my boss insist we only use the ones provided by say Facebook or Twitter themselves (in fear of getting sued or lose credibility), but sometimes it just doesn't look very good on the site.   What is the common practice for these things? What do you risk by using an altered logo? What should I tell my boss?  I'll provide a few examples, what'd happen if I put any of these on a site? Calculating $\lim_{x\to+\infty}(\sqrt{x^2-3x}-x)$ Let $f(x) = \sqrt{x^2-3x}$ and $g(x) = x$. Calculate the following limits, showing all working.  I've done the first two -   $$\lim_{x\to0}f(x)\\ =\lim_{x\to0}\sqrt{x^2-3x}=0$$  $$\lim_{x\to-\infty}\frac{f(x)}{g(x)}\\ =\lim_{x\to-\infty}\frac{\sqrt{x^2-3x}}{x}=\sqrt{1-\frac{3}{x}}=1$$  How do I calculate this one?  $$\lim_{x\to+\infty}(f(x)-g(x))$$ Words to describe people with good/poor vocabularies Words to describe people with good/poor vocabularies.

If that tag lacks the name attribute, I want to implant my own attribute. The result should look like this:  &lt;IMG name="img1" ...&gt; =&gt; &lt;IMG name="myImg1" ...&gt; &lt;IMG ...&gt; =&gt; &lt;IMG name="myImg1" ...&gt;   Can this be done with a single line regex? For example, this regex  (.*)&lt;FooBar&gt;   will match:  abcde&lt;FooBar&gt;   But how do I get it to match across multiple lines?  abcde fghij&lt;FooBar&gt; It started happening today... all of a sudden, no apparent reason!

It  to disable internet search results in start menu searches before the Windows 10 Creators Update, but I've just clean installed a new Windows 10 Pro image and that setting is gone.

The Lie algebra of a Lie group is the set of all the left invariant vector fields, but how would you determine them?  My group is the set of all affine maps $x \rightarrow A.x+v$ from $R^n$ to $R^n$ under function composition. During the First Wizarding War, why didn't Dumbledore just hunt Voldemort down, as he had done with Grindelwald?  By 'hunting down', I mean finding, defeating and imprisoning him, exactly as in Gridelwald's case, and not, say killing him, something which Dumbledore would not do, as the answers to a previous question (as to him not hunting down Death Eaters) show.  Dumbledore knew that Voldemort had delved into the Dark Arts deeper than anyone else in history and hence "had powers he will never have". But he must have also known well that he could have defeated Voldemort at a direct confrontation, given that he had defeated Grindelwald earlier even against the Elder Wand, and now had that same wand at his disposal. He is seen confident about this throughout the series.  At the Battle of the Department of Mysteries, he did not go beyond outweighing Voldemort and forcing him to flee, probably because, by then, he had reasons to suspect that there was more to Voldemort's survival than his physical body, and thus, destroying that body which had Harry's blood without permanently disposing him off would not have been wise.  But why did he not do that at the First Wizarding War? Is it just that they could not track him down, or did he suspect even then that Voldemort had more sinister things about his soul? is there any canon confirmation of the latter suspicion? Regex for splitting a string using space when not surrounded by single or double quotes I know that VARIABLE=value creates an environment variable, and export VARIABLE=value makes it available to processes created by the current shell. env shows the current environment variables, but where do they live? What comprises an environment variable (or an environment, for that matter)? Is there a difference between taking a far shot on a 50mm lens and a close shot on a 35mm lens? Where such a term would reference the location/time of an object, almost like it was of a property of the object. That is to say, if a duck is red, blue, yellow etc, we describe it has having a certain colour. If it's a nanometre, or 10km big, then it's property of size.  Now I know that where/when an object exists an object isn't a property of an object, but it is something unique to that object, so I think it would be useful to have a shorthand for 'geographical location', and 'time of existence'.  There are terms describing both time and location, such an event, or rendezvous (which I think is used to describe the when and where of a meeting between two humans) but I wan't a term that just describes one of each. Why doesn't Java allow to throw a checked exception from static initialization block? Why is the even root of a number always positive? Let $n \in \mathbb N$ be a natural number and $a \in \mathbb R$ be a real number. The $n$-th root of the number $a$ is defined as follows:  Case I: $n$ is an odd number. In this case the $n^{\text{th}}$ root of $a$ is defined to be that number $b \in \mathbb R$ such that $b^n = a$.  Case II: $n$ is an even number. In this case the $n^{\text{th}}$ root of $a$ is defined to be that number $b \geq 0$ such that $b^n = a$.  Why is it that when $n$ is even, we only consider $b \geq 0$. For example, both $+2$ and $-2$ squared equal $4$, but when we say the square root of $4$ is $2$. Is there a reason for this?
