I would like to network a farm building which is 500' from my house. There are lots of trees between the two, so I doubt that wifi would work. 300' is the max length for Cat 5 ethernet cable.  What are my options? I could have a small solar panel and battery at the other end for power, but I don't have mains power there.  If there is a cabled solution I can trench to there and run cable through conduit.
As the title suggests, I have some kit which is 200m from our current infrastructure (outdoors).  What is the cheapest way to establish a reliable connection across a 200m stretch (Cat 5e ethernet only works up to about 100m from our tests)?
I need to run Firefox browser from terminal. Browser works fine, but terminal still waits for Firefox to return and if I do CTRL+C, it terminates Firefox. How to run command to make Firefox work independently from terminal? postgresql - replace all instances of a string within text field I am trying to prove:     $a\mid b \land b\mid c \Rightarrow a\mid c $   $a\mid b$ means that a divides b if there is an integer k, that $b=k\cdot a$  Please give me a hint on how to start, because I have no idea. How do I display a decimal value to 2 decimal places? When displaying the value of a decimal currently with .ToString(), it's accurate to like 15 decimal places, and since I'm using it to represent dollars and cents, I only want the output to be 2 decimal places.   Do I use a variation of .ToString() for this? How does the Ready action work? So from reading the Player's Handbook, it seems that the Ready action is taken instead of any other action as it is an action in its own right. However, can you move on the same turn that you ready an action? For instance, (taking the example from the Player's Handbook):     If the cultist steps on the trapdoor, I’ll pull the lever that opens it   Presumably, when you ready this action, you would want to move near to the lever so you can pull it when the time is right. Likewise, with readying a spell, you would obviously want to move away from combat so you could concentrate on the spell.  Secondly, when the trigger goes off do you have to wait for your turn, or do you in effect get a bonus turn? For instance, the cultist starts running towards you, but on his way he steps on the trap door - so you immediately pull the lever, even though it wasn't your turn. I assume you then act as normal when your actual turn comes around? TikZ is undergoing lots of development with new features being added, but the versions distributed with standard TeX releases are often a little old. How do I get the latest version? If I want to be sure that I get the latest stable version, how do I do that?    Note: I'm not asking this question for myself, but because a question like this seems to be useful for pointing to it when a new feature of TikZ is mentioned in an answer to some other question. Feel free to post answers for any operating system/TeX distribution combination. Prove the identity $\binom{2n+1}{0} + \binom{2n+1}{1} + \cdots + \binom{2n+1}{n} = 4^n$ I've worked out a proof, but I was wondering about alternate, possibly more elegant ways to prove the statement. This is my (hopefully correct) proof:  Starting from the identity $2^m = \sum_{k=0}^m \binom{m}{k}$ (easily derived from the binomial theorem), with $m = 2n$:  $2^{2n} = 4^n = \binom{2n}{0} + \binom{2n}{1} + \cdots + \binom{2n}{2n-1} + \binom{2n}{2n}$  Applying the property $\binom{m}{k} = \binom{m}{m-k}$ to the second half of the list of summands in RHS above:  $4^n = \binom{2n}{0} + \binom{2n}{1} + \cdots + \binom{2n}{n-1} + \binom{2n}{n} + \underbrace{\binom{2n}{n-1} +\cdots \binom{2n}{1} + \binom{2n}{0}}_{\binom{m}{k} = \binom{m}{m-k} \text{ has been applied}}$  Rearranging the above sum by alternately taking terms from the front and end of the summand list in RHS above (and introducing the term $\binom{2n}{-1} = 0$ at the beginning just to make explicit the pattern being developed):  $4^n = (\binom{2n}{-1} + \binom{2n}{0}) + (\binom{2n}{0} + \binom{2n}{1}) + \cdots + (\binom{2n}{n-1} + \binom{2n}{n})$  Finally, using the property $\binom{m}{k} + \binom{m}{k-1} = \binom{m+1}{k}$ on the paired summands, we get the desired result:  $4^n = \binom{2n+1}{0} + \binom{2n+1}{1} + \cdots + \binom{2n+1}{n}$ Can I use a custom Splash screen?

As it stands, there is raw HTML (an href) in the description:    EDIT: after reading comments by @ColeJohnson, I have come to the understanding that this post comes off as whiny. I want to make it very clear that I wasn't ever trying to complain. My first reaction was to fix the perceived error myself. When I realized I was unable to do so, I figured the best course of action would be to find someone who would be able to make the necessary edits. Hence the post here. Best approach to Windows Forms rolling log output in TextBox In Windows 7, How to query times, when the computer was locked? Is there a way to get a list of the following times:  whenever windows is locked (using windows+l combo)  whenever windows is unlocked in the past week?   I've tried poking in the event log, to no avail. Many thanks! Note that this is only focusing on Minecraft Java Edition, and for versions 1.13+. I am predominantly looking for a solution that does not require any external programs (like MCEdit or NBTExplorer) and will work in just plain vanilla Minecraft, although if the only solution doesn't fit these criteria, I'll still take it (since having a solution is better than no solution!) Essentially, I am looking for a way to put a phrase (meaning essentially there are two or more words and spaces are involved) on a Minecraft scoreboard. This is what I mean by 'phrase': One two three, 1 2 3 These are not 'phrases': OneTwoThree, One-Two-Three, One_Two_Three, 1-2-3, etc. However, it seems like the only way to add text to an objective on the scoreboard is to add a &quot;fake player&quot;, via /scoreboard  players add [playername] [objectivename] [score], which shows the [playername] and the [score] part of the command on the scoreboard. However, since player names can't have spaces at all, it means that you can't have a phrase shown on the scoreboard. I have seen on many servers scoreboards that do have phrases listed on the scoreboard, but I have no idea how they do this (probably because of plugins that can do this sort of thing).  I did notice that teams can be given display names that can have spaces, so is there a way to display the team name on the scoreboard (thus being able to put phrases on there?)? Overall, my main question would be &quot;Is there a way to use spaces on the scoreboard (excluding the objective name) in vanilla Minecraft? I would like to be able to change the default CSS used by chrome, such as removing the underlines for links, etc. However, I cannot find the default CSS file used by Chrome. Does anyone know where it is? Are those stars moving past the window when the ship is at warp? When the enterprise (ENT) is moving at warp we see numerous stars flying past in the windows:    However, according to , at warp 5 (the maximum speed of the 1st enterprise) it would take 7.4 days to get from the Sun to Alpha Centari, our nearest star(s) approximately 4 light years away. So to have stars whizzing past every few seconds would imply that the stars are very close together.  Is this an inaccurate depiction of star movement at warp, or is there some explanation like the warp bubble creates a lensing effect?  Now I realise the classic answer is "suspend your disbelief, it's a tv show", but the animators have at least thought about the star movement as they have added in a bit of red shift and blue shift which you can see in the image.
