I want to play Minecraft but I have one controller only. I do have a PC as well. Can I play PC and PS4 Minecraft?
My kids are playing Minecraft on 2 PCs, creative mode.  They are connected by the way of one of them starts a single player game on the other one than joins that game over the LAN.  Can I, using Minecraft PE on my iPad, join their game as well?
Solve $$\int \limits_{0}^{\infty} \frac{\cos(x)}{\cosh(x)} dx$$ without complex integration.  This integral can be very easily solved with contour integration, but how can you solve it without taking a tour in the complex plane? Linux: coloring bash prompt will break carriage return How can you reduce ambient noise from servers? I almost always want the profile correct applied, but it's an extra step. Any ideas on how to apply these automatically? Fred and George Weasley are known for their trouble-making and general &quot;solemnly swearing they are up to no good&quot;. Their antics/adventures give something to smile about and show us not all wizards are as serious as Professor McGonagall and Hermione. This gives them a reputation of being less intelligent and indeed they only achieved three OWLs. However, we also see the twins have quite a brilliant side! Being able to open and successfully run a shop in Diagon Alley without having completed their Hogwarts education is no easy take (IMO, anyway). Their creations helped students get out of class, our heroes out of tight spot, and even stop our enemies execute an evil plot. Ginny may have said it best:  &quot;We’ve been hearing explosions out of their room for ages, but we never thought they were actually making things,&quot; said Ginny. &quot;We thought they just liked the noise.&quot; Harry Potter and the Goblet of Fire  Do we know how many things Fred and George invented? Which one is the best option to get the identity value I just generated via an insert? What is the impact of these statements in terms of performance?   SCOPE_IDENTITY()  Aggregate function MAX() SELECT TOP 1 IdentityColumn FROM TableName ORDER BY IdentityColumn DESC I understand that the letter "J" is relatively new — perhaps 400–500 years old.  But since there has long been important names that begin with J, such as Jesus, Joshua, Justinian, etc., and which predate the introduction of a special letter, does that mean that the "J" sound predated the letter, or were such famous names spelled and pronounced differently? What is the most straight forward way to downgrade Firefox 57 to Firefox 56?   This is to have more time to wait for working replacements for legacy extensions. Counting number of vertices of polygons and lines in QGIS? In QGIS, is there a way to count the number of vertices of polygons and lines in a given layer, and create a separate field containing these values?   I suspect it's a function somewhere in the field calculator but I can't find it. Linux network troubleshooting and debugging From time to time Linux and Unix users faced with various network problems. Many of these problems are presented here and at some others troubleshooting forums, but they are very concrete and contains a lot of additional technical information, and sometimes it's rather difficult to understand the main point and the real reason of buggy system behavior.   By asking this question, my intention is to start a community wiki page which allows generalizing our network troubleshooting and debugging experience. I hope the Linux and Unix users could easier recognize and solve("divide and conquer") their network problems using this page.   The parent of this page should be  . But here we should focus on troubleshooting the network problems from user- and kernel-space.  I suppose, if you:    Share the information about using some great network diagnostic tool with concrete usage examples and examples of network bugs, which they help to catch. Share the link to the great network tutorial connected with this subject Tell about a general method or recipe which allows to tackle some class of network problems Share information about your tool-set for network debugging and troubleshooting   it would perfectly fits for this topic.    I'll begin from sharing the link to varios  and . Also  seem to have actual information about our subject. And for diving into linux networking we definetely need to visit . I am a dual Australian/British citizen with an expired emergency Aussie passport and a valid UK passport. What are my chances for an Aussie visit? I was going to have to miss my brother's wedding on Jan 4th but he bought me a flight today. But my Aussie passport is expired and was only an emergency passport to begin with. I'm born and bred Aussie, just been away for ten years. I'm hoping to arrive on UK passport, show the expired Aussie one and the wedding invite and my return ticket for two weeks later and hope they understand.   What are my chances? Also planning on going to the Aussie embassy on Monday to see what they say but want to know my chances of just entering on a UK passport. Synchronize Clocks I need to develop a system where there are 4 sensor boxes powered by USB and they have their internal clock. Each of these boxes are connected to a Linux pc and all these PCs are linked with WiFi. API of the sensor box allows me to read their internal precision clock (uSec accuracy).   I like to synchronize all four clocks of the sensor boxes as close as possible. Hopefully within a few micro seconds of each other and compensate for drift over time. The idea is to use the sensor data that is collected at the same time (The data I receive is time stamped with the boxes' internal clock). The latency on usb bus, WiFi, pc timing are all indeterministic.  Is this possible given my setup? Can't find boot-repair package for the newest version of Ubuntu After upgrading Ubuntu 13.10 to 14.04, grub failed to load Ubuntu and threw the error symbol 'grub_term_highlight_color' not found. I followed the solution offered in the  but this failed for me, throwing the error failed to get canonical path of /cow.   Now, I'm trying to install Boot-Repair to fix this problem on a live pen-drive, using these commands.   sudo add-apt-repository ppa:yannubuntu/boot-repair sudo apt-get update sudo apt-get install -y boot-repair &amp;&amp; (boot-repair &amp;)   But after adding and updating the repositories, it shows ppa:yannubuntu/boot-repair 404 Not Found error.  W: Failed to fetch http://ppa.launchpad.net/yannubuntu/boot-repair/ubuntu/dists/trusty/main/binary-amd64/Packages  404  Not Found   Is this problem solvable or is there an alternative PPA for Boot-Repair? Another way to write least prime factor.

Without any special operators, LIKE and = are the same, right?
