Why should I make a yeast starter and not just sprinkle the yeast on top of the wort like the packet says? I am sure there must be some good reason why you would do this.
I have noticed that the smackpacks say on the package that the package is meant for a 5 gal. batch and that you should pour the pack directly into the wort.   On the otherhand - nearly everyone tells me to always make a starter.   Is this just because making a starter never hurts or does the package contain wrong instructions?   I would have guessed that the yeast producers would tell you on the package if you should need some extra steps to get a good product.
No connection could be made because the target machine actively refused it (PHP / WAMP) Which is more appropriate in the following sentence?     "I asked him to not judge her according to (or: based on) her beauty"   vs     "I asked him not to judge her according to (or:based on) her beauty"   or maybe you wouldn't choose either of the above, but something else? Elements order in a "for (… in …)" loop Does the "for…in" loop in Javascript loop through the hashtables/elements in the order they are declared? Is there a browser which doesn't do it in order? The object I wish to use will be declared once and will never be modified.  Suppose I have:  var myObject = { A: "Hello", B: "World" };   And I further use them in:  for (var item in myObject) alert(item + " : " + myObject[item]);   Can I expect 'A : "Hello"' to always come before 'B : "World"' in most decent browsers? How to prove that $\frac{(mn)!}{m!(n!)^m}$ is an integer? $\forall m,n\in\mathbb Z$ , $m\ge1$ and $n\ge1$ how to prove that  $$\frac{(mn)!}{m!(n!)^m}$$ is an integer?  Thanks in advance. Can one executable be both a console and GUI application? I want to make a  program that can be run as a CLI or GUI application depending on what flags are passed into it. Can this be done?  I have found these related questions, but they don't exactly cover my situation: Did this character even qualify for being Azor Ahai or The One Who Was Promised? In the books and to some degree in the show as well there is a prophesy about the legendary figure Azor Ahai. But in the latest Game of Thrones episode (S08E03) we see Arya      killing the Night King.   However in a  we discussed​ all possible candidates but nobody thought about Arya. Does she even fulfill the prophecy? If she does, how? The minimum system requirements for 18.04 are "2 GHz dual core processor or better"; would a quad-core at 1.8 GHz meet (or approximate) this requirement? How can I format my active hard drive to NTFS? I'm trying to install Windows 7 with a 4GB flash drive, but my error that comes up is that my hard drive I'm trying to install on is in ext4. I need to format it to read NTFS. I can't seem to find any topics on how to format an active hard drive. I found a topic that explains how to move Ubuntu to a new drive, but it's a bit confusing to me. I have reviewed both related posts on this site:      The issue I am having is that I have implemented the registry change, rescanned my websites, and I am still being told that IIS 6 is allowing SSL 2.0 connections.  Here's the verbage from the scanning site:     Synopsis : The remote service encrypts traffic using a protocol with known weaknesses. Description : The remote service accepts connections encrypted using SSL 2.0, which reportedly suffers from several cryptographic flaws and has been deprecated for several years. An attacker may be able to exploit these issues to conduct man-in-the-middle attacks or decrypt communications between the affected service and clients.   QUESTIONS:   How do I test this myself so I can continue to troubleshoot the issue? Is there a tool out there that I can use to test? Would I need to disable other connection methods?

I was trying to install minted package in TeXLive. I installed it and then run sudo tlmgr update --all. It was running slow so I stopped it using Ctrl+Z in an ubuntu terminal and then I run sudo tlmgr update --list. After that I installed texlive-latex-extra and python-pygments.

How do I get my external IP address  from the Windows and Linux command line? On Windows, ipconfig shows an internal network IP address, but it does not show the external one. Solving 2-degree equations in 3 variables. We are given 3 equations: $x^2+\sqrt3 xy + y^2 = 25$ $y^2 + z^2 = 9$ $x^2 +xz+ z^2 = 16$. $x,y,z$ are positive real numbers. Then we have to find value of $xy + 2yz + \sqrt3 xz$. Why do all SSH-RSA Keys begin with "AAAAB3NzaC1yc"? How to make a series of rectangles follow a pen path I am trying to get a series of shapes (rectangles) to follow a path (sine wave) that I made with the pen tool, but I have no clue how to do that or if it is possible.   I have tried warping a rectangle into the sine wave path, but it takes many different warped rectangles and it isn't smooth.  I thought  might work for rectangles, but it only works for text. Access server by host name? I have a mixed network with mostly Windows machines, a Mac, and a few Linux boxes.  There is no DNS or WINS server, and adding one is outside of my control.  If I put a clean install of 10.04 desktop on a computer, then all other machines on the network can get to that machine by hostname just fine.    However, if I put 10.04 server on the same computer, then the other machines can only get to it by IP address.  The hostname does not resolve.  What do I need to do on the server so that all the other machines on the network can get to it? I've got this situation:  ./ ./myscript.sh ./arguments.txt ./test.sh   Inside myscript.sh, I have to run the file test.sh, passing to it the arguments contained inside arguments.txt.  myscript.sh is:  arguments=$(cat arguments.txt) source test.sh $arguments   This works well if if arguments.txt contains at most one argument:  firstargument    The substitution is:  ++ source test.sh 'firstargument'   But the problem is with two or more arguments. It does this:  ++ source test.sh 'firstargument secondargument'   Also, I don't know in advance the number of arguments inside arguments.txt. There can be zero or more. Class imbalance in Supervised Machine Learning Maximizing expected value of coin reveal game I was asked this question today in an interview and am still not sure of the answer. The question is as follows.   Part one:  Say I have flipped 100 coins already and they are hidden to you. Now I reveal these coins one by one and you are to guess if it is heads or tails before I reveal the coin. If you get it correct, you get $\$1$. If you get it incorrect, you get $\$0$. I will allow you to ask me one yes or no question about the sequence for free. What will it be to maximize your profit?  My approach for this part of the problem was to ask if there were more heads than tails. If they say yes, I will just guess all heads otherwise I just guess all tails. I know the expected value for this should be greater than 50 but is it possible to calculate the exact value for this? If so, how would you do it?   Part two: Same scenario as before but now I will charge for a question. I will allow you to ask me any amount of yes or no questions as I go through this process for $\$1$. What is your strategy to maximize your profit?  I was not sure about the answer to this part of the question. Would the best option be to guess randomly? I think the expected value of this should be 50. I am not sure about the expected value of part one but if it is greater than 51, I think I could also use that approach. Anyone have a good idea for this part? How can I display additional boot and shutdown information on the Windows 7 welcome screen? There is a small tweak, I believe it is a registry key, that allows to display additional information on the Welcome and Shutting down screens of Windows 7 (and most likely Vista, too). I have activated this tweak on one of my systems; unfortunately I forgot how I did it, and I can't seem to find the website that originally gave me that information.  Usually, the Windows 7 welcome screen will just display "Welcome" when logging in. With the tweak activated, my Welcome screen gives status information such as "Loading user settings" or "Preparing desktop". When shutting down, the default screen simply says "Shutting down". With the tweak activated, it gives additional status information such as "Stopping Windows services". This appears the same way that Windows gives information when updates are installed or configured during the startup or shutdown procedure, and I find them quite helpful in getting a feel for what task takes how long during that process.  The only setting I was able to find is the Boot log checkbox on the Boot tab of the msconfig application. However, this results in Windows displaying console logs of drivers it is loading, etc., instead of the animated Windows title. This is NOT the setting I am looking for. The "additional boot information" setting that I have activated on this system still displays the regular animated Windows logo, and only replaces the strings displayed on the blue Welcome and Shutdown screens.  Could someone direct me to the registry key (or whatever setting) that is used to get this behaviour?  Edit: Here are a few pictures of the enhanced Welcome and Shutdown screens taken with my mobile phone—they're in German though.
