The communities section under profile, when empty, the empty state doesn't have space after the heading. This happens throughout the Stack Exchange network.  This happens everywhere. Update: I am unable to find this where it happens. Could even be a loading part. How did this come in BTW?
Padding is missing under the &quot;Communities&quot; border line, and the list is also showing &quot;Communities (0)&quot; (maybe the reason is due to caching as it shows 0 Communities):  Generally, padding is present:
Product of pairwise coprime integers divides $b$ if each integer divides $b$ Let $a_1....a_n$ be pairwise coprime.  That is $gcd(a_i, a_k) = 1$ for distinct $i,k$, I would like to show that if each $a_i$ divides $b$ then so does the product.  I can understand intuitively why it's true - just not sure how to formulate the proof exactly. I want to say if we consider the prime factorizations of each $a_i$, then no two prime factorizations share any prime numbers.   So the product of $a_1...a_n$ must appear in the prime factorization of $b$.  Is this correct?  Or at least if if the idea is correct, any way to formulate it more clearly? I have some files with different extensions such as *.pdf, *.mp3, *.jpg and a few others. All of them are stored in a parent directory.  How can I get a list of all extensions, create some folders based on these  extensions and then move all files into their relevant folders? What IDE to use for Python? What IDEs ("GUIs/editors") do others use for Python coding? So far, I didn't have the chance to use either of these services. Before starting, I would like to hear your opinions. What are the advantages and disadvantages? Why should I choose one over the other? I am mainly interested in the technical side, but I would also love to hear comments also regarding the plans and prices. What is the difference between String and string in C#? Playing Minecraft on Windows 10, owning a Xbox One disc I own a Minecraft disc for an Xbox One, and would like to play on my PC (ultimately, playing with others who will be on the Xbox).  I'm not too familiar with the Xbox account ecosystem, and with dozen different Minecraft editions, I'm lost as to how I can do that. What's the meaning of "be blowed"? I would like to know what's the meaning of "be blowed" in the following text:     'I'm going to smoke' Jenkins said; 'be blowed to Bertie dear.' (Mrs. Smythe had once addressed her husband in the office as 'Bertie dear', and thereforth that had been his name among the staff.) Richard made no answer. When a minute later Jenkins, discreetly directing his puffs to the open window, asked him for the titles of one or two of Zola's novels in English, and their price, he gave the required information without turning round and in a preoccupied tone.   , Arnold Bennett, 1911. I am interested in setting up a Ruby on Rails environment on my 10.10 laptop.   Is there anything special I need to keep in mind for installation (i.e. that could be new or unique to 10.10)?   Are there any suggested walkthroughs that I could follow along with?  Thanks in advance. Unknown apps/processes with number only are shown in data usage A mysterious app named &quot;10102&quot; shows up in my data usage. It bears only the standard Android app icon (the Bugdroid logo with a cube on its torso). From what the graph tells me, it has used 36 megabytes of data in the background and zero on the foreground. I think I haven't uninstalled anything for months. Is it malware? I haven't sideloaded anything and only authorized my laptop as a USB debugger. If it's malware, how do I remove it? I have no idea how to find its package name and 10102 isn't in the list of downloaded apps in settings. I'm running stock &amp; never-been-rooted Android 4.4.4 on Nexus 4. Mining cryptocurrencies with Ubuntu and sgminer What are the steps for setting up a Ubuntu machine for mining of crypto-currencies?  I am looking for a full guide to follow - from installing Ubuntu to how to config and start the miner itself. I checked this  but didn't fully understand it.   I know that the volume of a right circular cone is $V = \frac{1}{3}\pi x^2h$  I know that I must take the first derivative and set it equal to zero, which will find the maximum.   My problem is how to deal with the variable $h$, the height?   How can I rewrite that in terms of $x$ or $r$.      I have tried to implicitly differentiate this equation, but that wasn't helpful for me. Any javascript event occurring when user clicks Stop load button? How do I change the cursor and its size? How to find perpendicular vector to another vector? How do I find a vector perpendicular to a vector like this: $$3\mathbf{i}+4\mathbf{j}-2\mathbf{k}?$$ Could anyone explain this to me, please?  I have a solution to this when I have $3\mathbf{i}+4\mathbf{j}$, but could not solve if I have $3$ components...  When I googled, I saw the direct solution but did not find a process or method to follow. Kindly let me know the way to do it. Thanks. Nginx Subdirectory returning 404 I currently have a bunch of working static files at the domain name khairulslt.me (from NameCheap). Recently, I've tried setting up a subdirectory (khairulslt.me/RGBGame) as seen in the code below; However, I keep getting 404 errors. What am i missing out?  server {    server_name khairulslt.me www.khairulslt.me;    autoindex off;   location / {     root /var/www/khairulslt.me;     index circles.html;   }   listen 443 ssl; # managed by Certbot ssl_certificate /etc/letsencrypt/live/khairulslt.me/fullchain.pem; # managed by Certbot ssl_certificate_key /etc/letsencrypt/live/khairulslt.me/privkey.pem; # managed by Certbot include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot  location /RGBGame {     root /var/www/khairulslt.me/RGBGame;     index colorGame.html;     try_files $uri $uri/ /var/www/RGBGame/colorGame.html?q=$uri&amp;$args;     autoindex off;   }  location /robots.txt { return 200 "User-agent: *\nDisallow: /\n";    }  }   server { if ($host = www.khairulslt.me) {     return 301 https://$host$request_uri;   } # managed by Certbot   if ($host = khairulslt.me) {     return 301 https://$host$request_uri;   } # managed by Certbot   listen 80; server_name khairulslt.me www.khairulslt.me; return 404; # managed by Certbot }   I've tried all the different settings like (alias vs root), try_files, autoindex(on, off). My main website www.khairulslt.me works fine and is serving the html/css/js files in /var/www/khairulslt.me perfectly fine. I'm just not sure why I can't replicate the settings for my other app (html/css/js files in folder /RGBGame). Could it be that I've missed out something that isn't related to the nginx config? Lookup City and State by Zip Google Geocode Api I have a British passport from 2006 September and going to Florida. The passport in has camera symbol. Is it valid? I am going to Florida in a few days. I have a British passport that I acquired in September 2006. It has a "camera" symbol on front and is biometric. Just seen news items that only passports from October 2006 or later will be accepted by the USA. Is my passport valid for travel to the USA? I do have a valid ESTA. Find the Values of $p$ and $q$ such that $\int_0^{\infty} x^p\ln(1+x)^q dx$ Converges or Diverges. The question is to find the value values of $p$ and $q$ such that the improper integral converges or diverges.  My friend indeed found some values of $p$ and $q$ such that it converges, but after many trials, I am still getting divergent for all values.  Via L'Hospital, we have the following:  $$\lim_{x \to 0} x^c\ln(1+x)^q = \infty \space \text{when} \space  c &lt; 0$$ $$\lim_{x \to 0} x^c\ln(1+x)^q = 0 \space \text{when} \space  c &gt; 0$$ $$\lim_{x \to \infty} x^c\ln(1+x)^q = \infty \space \text{when} \space  c &gt; 0$$ $$\lim_{x \to \infty} x^c\ln(1+x)^q = 0 \space \text{when} \space  c &lt; 0$$  Thus, $$\int_1^{\infty} x^p\ln(1+x)^q dx = \int_1^{\infty} x^{p-c}x^c\ln(1+x)^q dx &gt; \int_1^{\infty} x^{p-c} dx$$ which diverges when $p &gt; -1$.  Here, we set $c = \frac{1}{2}(p+1) &gt; 0$.  On the other hand, $$\int_0^1 x^p\ln(1+x)^q dx = \int_0^1 x^{p-c}x^c\ln(1+x)^q dx &gt; \int_0^1 x^{p-c} dx$$ which diverges when $p &lt; -1$.  Here, we set $c = \frac{1}{2}(p+1) &lt; 0$.  Thus, the integral diverges whenever $p \ne –1$.  Then, let $p = -1$.  $$\int_0^{\infty} \frac{1}{x}\ln(1+x)^q dx = \int_0^1 \frac{1}{x}\ln(1+x)^q dx + \int_1^{\infty} \frac{1}{x}\ln(1+x)^q dx $$ $$ \ge \int_0^1 \frac{1}{x+1}\ln(1+x)^q dx + \int_1^{\infty} \frac{1}{x+1}\ln(1+x)^q dx $$  The first summand diverges when $q &lt; -1$ and the second diverges when $q &gt; -1$.  Finally, let $ p = -1$ and $q = -1$.  The integral $\int_0^{\infty} \frac{1}{x\ln(1+x)} dx ≥ \int_0^{\infty} \frac{1}{(x+1)\ln(1+x)} dx$ diverges on both ends.  Did I make a mistake?
