I have a portable mini wireless router with different functions (AP/Client/Router).  Can I use a ethernet splitter to give internet access to two devices? The router only has a ethernet port and connects to a wireless network (Cliente mode).  I know that a switch would be the best option but I dont have one and they are expensive.
I have one Ethernet port that is wired directly to the router on another level.  However, I want to run a desktop and a server both off this one Ethernet port.  Can anyone tell me the difference between an Ethernet splitter and a switch?    Also, will either the splitter or switch slow down the connection as opposed to just one connection?
I have played and tried to GM games since I was in elementary school, beginning with games like Shadowrun, Earthdawn, and Champions. Recently, I've gotten dack into gaming with a variety of other games (newer Shadowrun and Earthdawn, plus TOON! and Outbreak:Undead).  I've found examples of actual play and advice on how to actually GM a game in games to be lacking. I can only help but feel I am not alone as someone who isn't already a LITERAL dungeon MASTER.  I fully realize that there are an unlimited number of GM styles, personalities, etc. I do not think I am a very good GM though. No one else wants to be the GM, and few care enough to learn the complex rules that I often have to assist with and explain AS WE PLAY. Being left with the responsibility is quite overwhelming unless I create dynamic encounters or make it all up on the spot. I'm often left having no idea what to do.  Examples of Why I Think I Need Help  This question isn't about these examples so please don't dig into them in the answers - they're here to explain the basic things that leave me feeling like I don't know how to proceed as a GM.  I've read preparation is important, but last time I tried to make a story, the players immediately killed the primary character (a friendly person.) within about 2 minutes of starting the game. While I realize now that I let the dice take control over the story, it was rather difficult to continue a story that relied on this friendly character, with the players making enemies with the character's faction. It is still discouraging when my only other attempt at a prepared story ended with the players wanting to go in a complete opposite direction of where I planned. Both times, the hours of work I put into it were completely wasted, leaving me as ignorant as I always was before.  My group often wants to play Shadowrun, Earthdawn, or L5R- but I feel as though I am a horrible GM. The last time we played Shadowrun, I was bored out of my mind as we rolled hundreds of dice to do an obvious straight-forward "kick down the door" mission.   If I make security as I believe it should or as the forum threads describe their security or a few example missions I can scrounge up (examples of stories, not actual gameplay), my players literally feel completely hopeless as to how to achieve their mission without total failure.   One time when I was a teenager, I had players blow up at me saying "We have no idea what would work. You're telling us that our character's experience or the ally operative says that would get us killed, but what else can we do?" Since there are no examples of what players can do - I am left with the same feeling as the players. As an adult, I've had a similar occurrence where a player said to me, "I don't know what to do. I don't think we can even begin this mission." I had to make something up and just go with it, creating an NPC group (that fit in with the story) that goes in before the players to do something stupid so they don't have to. Mainly because I ALSO didn't know how to accomplish the mission, so I acted as the players would using my NPC group. Extremely boring and IMO a failed dungeon run.  I've had successful stories, but I've had more boring encounters than successful ones. Seeing as how roleplaying takes endless hours to complete a story, I do not see benefit in an activity that wastes more time than is enjoyable.  How Do You Learn To GM?  Where are the resources? Books, blogs, gameplay examples? Am I missing them? How did YOU learn to be a good GM? Or do you feel as bad at this as I do, even when it's a successful, fun encounter? Permanently blocking a domain in iptables Suppose I want to block Facebook permanently. To do this, I have followed following processes:     #host -t a www.facebook.com   Sample output:     www.facebook.com has address 69.171.224.40   Find CIDR     #whois 69.171.224.40 | grep CIDR   Sample output:     CIDR:           69.171.224.0/19   To prevent outgoing access to www.facebook.com  Approach 1:     #iptables -I FORWARD -p tcp -d 69.171.224.0/19 -j DROP   Approach 2:     #iptables -I FORWARD -p tcp -d www.facebook.com -j DROP   Both Approaches work well. In approach 1, IP address may be changed so it will not block Facebook permanently. I don't know about approach 2 whether it will block Facebook permanently or not. If above approaches are not right way to block a domain permanently, how can I do it? Bearing in mind I am a layman - with no background in physics - please could someone explain what the "big deal" is with quantum entanglement?  I used to think I understood it - that 2 particles, say a light-year apart spatially, could affect each other physically, instantly.  Here I would understand the "big deal".  On further reading I've come to understand (maybe incorrectly) that the spatially separated particles may not affect each other, but in knowing one's properties you can infer the other's.  If that it the case, I don't see what the big deal is... 2 things have some properties set in correlation to each other at the point of entanglement, they are separated, measured, and found to have these properties...?  What am I missing? Is it that the particles properties are in an "un-set" state, and only when measured do they get set?  (i.e. the wave-function collapses).  If this is true - why do we think this instead of the more intuitive thought that the properties were set at an earlier time? Available space not changing when resizing a partition In my computer I have several partitions. I have one partition with Fedora that had just below 40 GB of space, and which I wanted to make bigger. Therefore, using GParted, I moved 10 GB from another partition to the Fedora partition. Now, according to GParted, I should have just below 50 GB (see sda12):  However, from Fedora itself the available space looks different:  This was the same space that was available before I resized the partition. How do I make that space actually available to Fedora? Does a photon exert a gravitational pull? Performing multiple layer intersection in QGIS? Is there a way to achieve the equivalent of a  in javascript regular expressions?  I need to match a string that does not start with a specific set of characters.  It seems I am unable to find a regex that does this without failing if the matched part is found at the beginning of the string.  Negative lookbehinds seem to be the only answer, but javascript doesn't have one.  EDIT: This is the regex that I would like to work, but it doesn't:  (?&lt;!([abcdefg]))m  So it would match the 'm' in 'jim' or 'm', but not 'jam' Solving a Diophantine equation with a large solution I'm reading . Then I'm not able to figure out the difference between hard voting and soft voting in context to ensemble based methods.  I quote descriptions of them from the book. The first two images from the top are description for hard voting, and last one is for soft voting.        In my view hard voting is majority decision, but I don't understand soft voting and the reason why soft voting is better than hard voting. Would anyone teach me these? I am very new to R. I am learning machine learning right now. Very sorry, if this question appears to be very basic.  I am trying to find a good feature selection package in R.  I went through Boruta package. It is a good package but I read that it is only useful for classification.  I want to do implement feature selection in R for regression tasks. I went through the caret package documentation but for my level, it is very difficult to understand.  Can any one please point me to a good tutorial or list any good packages or most frequently used packages in R for feature selection.  Any help would be appreciated. Thanks in advance. Broken image link on the new Stack Exchange blog Before I jump on to the problem, let me first congratulate  and his team for the newly re-designed Stack Exchange blog. I like it very much, great job! While searching on Google, I stumbled upon  blog post of Jeff Atwood and found few broken images. There are currently four images are broken on this post, Here is one of them:    Upon doing an inspect element on one of the broken image (same goes for all other broken images on the post), I found out that it is currently pointing to: https://blog.stackoverflow.com/wp-content/uploads/stackexchange-genuine-example11.png The newly re-designed Stack Exchange blog is now moved to a new location:  and the old blog URL i.e.  has the correct mapping of URL redirection (also called URL forwarding) and works perfectly. But, the problem lies in the latter part i.e. /wp-content/uploads/ directory structure does not exist anymore at the new blog location. I read the Jon Chan's  post (nice writeup! btw) where he talks about his custom Python script. Here is the relevant excerpt taken from that post:  I wrote a Python script to go through all the imported posts, looked for references to WordPress hosted content, download all the static assets into images/wordpress in the repo, and changed all the links to relative paths on Jekyll. Worked surprisingly well.  In other words, all of the old /wp-content/uploads/ static assets is now resides under the /images/wordpress/ directory at the new blog location. So, Jon's find and replace script should have worked (which it did for the most of the part) as intended to be but apparently it did not catch few of them. At least on  blog post and few other like ,  or . We could possibly have more but these are the ones I have found so far. I believe it's a minor bug somewhere in the script and could be fixed with few lines of code tweaking. Also, the static content link mapping problem would not have occurred at all if the directory name was unchanged as the URL redirection (as stated above) would have taken care of it. But, there must a reason for this change. Upon investigating further, I found out that the issue with broken images does not end here. They will still appear as broken even if Jon's script replaces the path to the correct one. Because the images have not been uploaded (or copied) to the blog's new /images/wordpress/ directory at all. They are missing! For example, try clicking on the following link: ## I replaced old dir. path /wp-content/uploads/ to the new /images/wordpress/  So, in a nutshell, in order to fix this broken images link problem, we need to make sure that not only they are pointing to new path i.e. /images/wordpress/ but also do exists (i.e. uploaded) at the blog's new location. Please fix this at your earliest. Apostrophes and double quotes don't show up until I type the next letter in Windows XP, when I type an apostrophe ', or  ", no character is displayed.  If I type another character, the apostrophe or dumb quote and the next character appear at the same time.  This happens with double quotes ", apostrophes ' and tilde ~ characters.  What could possibly be causing this?  This occurs in all applications I have tested - wordpad, firefox, ms word etc. Proving the Cauchy-Schwarz inequality by induction Multivariate linear regression vs. several univariate regression models In the univariate regression settings, we try to model   $$y = X\beta +noise$$  where $y \in \mathbb{R}^n$ a vector of $n$ observations and $X \in \mathbb{R}^{n \times m}$ the design matrix with $m$ predictors. The solution is $\beta_0 = (X^TX)^{-1}Xy$.  In the multivariate regression settings, we try to model   $$Y = X\beta +noise$$  where $y \in \mathbb{R}^{n \times p}$ is a matrix of $n$ observations and $p$ different latent variables. The solution is $\beta_0 = (X^TX)^{-1}XY$.  My question is how is that different than performing $p$ different univariate linear regression? I read  that in the latter case we take into consideration correlation between the dependent variables, but I don't see it from the math. How can I take screenshots of YouTube videos in full screen? I am trying to take a screenshot of a YouTube video in fullscreen.  When I pause the video and wait a moment, only the bottom UI bar (play/pause/seek) disappears. The top UI bar (Like/Share/More Info) stays there.  So when I press PrintScreen on the keyboard, the screenshot is polluted by this top UI bar. Is there any way to remove it while the video is on pause? Let $D := \{z \in \mathbb{C}: |z| &lt; 1\}$ and $f\colon D \rightarrow \mathbb{C}$ be holomorphic. Suppose $\lvert f(z)\rvert \leq 1$ on $D$, show that $$\frac{|f(0)| - |z|}{1 + |f(0)||z|} \leq |f(z)| \leq \frac{|f(0)| + |z|}{1 - |f(0)||z|} \ \forall z \in D.$$  I have tried using Cauchy Integral Formula to $f$ and expanding $f$ at $0$, but I have no idea why $f(0)$ appears in the inequality in the former case. Both answers and hints are appreciated and thanks in advance! How to access the Index Of A Generic.List By Reflection? ok, ive a class and i pass an object as property.  the object that i pass is a List&lt;X&gt;  in my class im trying to access the Object index by reflection BUT I CAN'T!!!   Example:  this class works i just wrote down the part i want to show you and i need help.  class MyClass {     private object _recordSet;     public object RecordSet     {         get { return _recordSet; }         set { _recordSet = value; }     }      public string Draw()     {         system.reflection.Assembly asem = system.reflection.Assembly.getAssembly(_dataSource.GetType());          object instance;          instance = asem.CreateInstance(_dataSource.GetType().UnderlyingSystemType.FullName);          //to access de Count of my List         int recordcount = int.Parse(_dataSource.GetType().GetProperty("Count").GetValue(_dataSource,null));          //i need to do a          for(int cont = 0; cont &lt; recordCount; cont++)         {             _dataSource[cont].Name; // &lt;-- THIS PART IS NOT WORKING!!! because i cant access the Index Directly.... WHAT TO DO!! ???         }     } } Unable to get a generic ResponseEntity where T is a generic class "SomeClass" Should questions include "tags" in their titles? How can I make a PATCH HTTP Callout from Apex? I need to make a PATCH http request.  I made the rather incredible discovery today that I can't set an HttpRequest to use the PATCH method, as when sending the request I get a callout exception:     System.CalloutException "Invalid HTTP method: PATCH"   The work around I've found on Stack Exchange and elsewhere is only applicable to a Salesforce Rest API request:    This is therefore not helpful to me as I'm calling out to a third party.  By what manner of magic can I send a PATCH request from Salesforce?  The only work around I can think of is to not do it from Apex - this is not an option.
