Step 1. In the directory where UE4 source is compiled, search for ‘EngineAnalytics.cpp’ and open it.

Step 2. Search for ‘bShouldInitAnalytics’ and set it to false.

Step 3. Recompile the editor.

Alternatively, if you have got the pre-built version, search for ‘UE4-AnalyticsET.dll’ and rename it (or delete it).

How to setup a Bukkit server

Lava Bucket; Bukkit logo
A bucket of lava resembles Bukkit logo

Bukkit is a tool that helps your shape and run your Minecraft server per your needs.

There are many types of Minecraft servers; the most popular ones are Vanilla(pure Minecraft), Bukkit and Tekkit.

The reason why I like Bukkit over others is it can be customized exactly as you wish and it doesn’t require players to have the same mods/plugins installed on their machines, as Vanilla does. Here is how to setup your own Minecraft Bukkit server:

Step 1. Go to CraftBukkit website and choose the version you want your server to run. I use this one, 1.7.2 Beta R0.3. Currently, Minecraft 1.6.4 is very old and has low plugin support. Development builds are very fresh and full of errors and unstable functions. Beta builds are your best bet.

Craft Bukkit site
Craft Bukkit download page

Step 2. Find the downloaded file and copy-paste it into a new folder on desktop called Bukkit Server.

Step 3. Now you have 2 options: to do it the hard way. or to use BukkitGUI.

1) The hard way

Open the folder where you copied Bukkit jar file. Rename it to craftbukkit.jar, then make a startserver.txt file and rename it to startserver.bat. Click yes if it asks you for file extension, then open the file and put this code in it:

java -Xmx1024M -jar craftbukkit.jar -o true
Bukkit server loading
Bukkit server loading

Where 1024M is the RAM memory you want to dedicate to your server. Feel free to change it.

Bukkit server loaded

Close the editor and run the file. First time it will be slow and it will create a bunch of folders and files. When it finishes, type in “stop” and press Enter. If you see a “Java is not recognized” error, go to this post to solve the problem.

2) Via Bukkit GUI

This is a very useful tool for server owners. If you choose to use it, you do not need to download Bukkit manually; it will do this job for you! I’ll cover this later on.

First, you need to download it from here, and copy-paste it to a folder, then run it. Wait for it to load. When it loads, click Super Start tab and select Bukkit in server type drop down. On the right you have a bucket with lava. In the Download # text box enter the build number (I recommend #3020 – latest beta version of 1.7.2) and click download. When it finishes, select your Java version from the drop down. Change the minimum and maximum RAM slider value, if you want. Remember that you need to double click a plugin that you want to install, then select the 1.7.2 R0.3 version(or the one you use). Click Launch server button and you’re good to go!

Port forwarding: part 1

Unless you already have a static IP address, you will need to configure it to be so. To do that the easiest way, install Port Forward Setup Static IP address program and open it.

Portforward default image
Portforward Setup Static IP Address; main screen

From the drop down choose you Wireless network if you are on Wireless or choose LAN if you are on LAN. If you expect to use both, do the following steps twice.

Step 1. Select your LAN/Wireless connection from the drop down and click Make it static button.

Portforward IP Settings

Step 2. Press OK button if you are satisfied with the current settings.

Step 3. A new window will appear. Wait for it to close.

Portforward Changing IP
Changing IP – this little windows will disappear quickly

Step 4. If the button reads Make it dynamic, then congratulations! It is finished!

Portforward - IP Changing finished
Portforward – IP Changing finished

Now, we need to know what is your IP address. To do this, just go here and Google will show you your current public IP address. People will connect to your Minecraft server via this IP.

Port forwarding: part 2

Now we have to make our router know for our server and allow it to communicate with other computers. Go to your router’s admin page (most likely to be or and enter the login credentials.

Forwarding - router settings
Forwarding – router settings

These settings are for a TP-LINK router, however, the options may be similarly named in your router.

Go here for help if you cannot find port forwarding settings.

Click the Forwarding link in the menu on the left and if it isn’t already selected, click Virtual Servers.

TP-LINK Router - Forwarding settings
TP-LINK Router – Forwarding settings

As we can see, our list of virtual servers is empty. Click Add New… button.

TP-LINK Router - Add New Screen
TP-LINK Router – Add New Screen

In the Service Port field enter your desired port (must be the same as the one configured in

In IP address text box, enter your static IP address and click the Save button.

Our current forwarding list
Our current port forwarding list

If you see this, that means that you have successfully configured port forwarding!


If you followed all the steps and everything went fine, this is all you have to do! Now you can start your server, enter Minecraft, go to multiplayer and add a new server. Remember, server IP is <yourcurrentpublicip>:<port>.

Always make regular daily backups! These are crucial if your server shuts down unexpectedly.

Your current server is portable; you can copy-paste it to your USB drive and carry it around, but the network you are in must have configured port forwarding and static IP address.

Sponges in Minecraft

Sponge; image from Minecraft Wiki

Sponge general info

Sponges are decoration blocks that have no other uses. In the upcoming 1.8 update, they are given ability to absorb water in 5x5x5 area and a new variant, wet sponge.

Currently they are obtainable in creative mode or via /give <name> 19 command.

Sponge uses

Before 1.8 sponges are used only for decoration.

Upcoming info about sponges

Starting from version 1.8(14w25a) sponges have 2 variants: dry sponge and wet sponge and a new ability to absorb water in 5x5x5 area. Their texture has also changed and they are again obtainable in survival mode.

Dry sponges turns to wet sponges after drying an area. Wet sponges are darker, full of water and unable to soak up more water. They can be dried in a furnace with any fuel. If you put a fuel so it starts burning, then replace the fuel with an empty bucket, after the process you will get a dry sponge and a bucket full of water. The most efficient way to use sponge is to start at the top and go down; sponges placed at the bottom will just result in water flooding the cleared area.

Sponges cannot be crafted and they spawn only in Ocean Monuments.

Cauldrons in Minecraft

Cauldron image; from Minecraft Wiki

General cauldron info

Cauldrons are blocks that hold water. They are crafted from 7 iron ingots and they always spawn empty in a witch hut. To fill a cauldron with water, right-click on the cauldron with a water bucket. A cauldron also has a chance to fill up with water when rained upon.

Cauldron uses and mechanics

Cauldron cannot be used to fill an empty bucket, and water bottles cannot be used to refill a cauldron, but a water bucket can fill a cauldron to it’s fullest. A cauldron can be filled from a water bucket in the Nether. You can fill up to 3 water buckets from a full cauldron.

A cauldron can act as a power source for a redstone comparator. With a cauldron behind it (possibly separated by an unpowered solid block), a comparator will output a signal strength proportional to how full the cauldron is: 0 for empty, 1 for one-third full, 2 for two-thirds full, and 3 for completely full.

When a cauldron is destroyed (dropping itself as an item), any water inside it will be lost, so it’s better to first pickup the water and then destroy the cauldron.

My opinion on cauldrons

They are very useful blocks. This way you can bring and store water in The Nether. Cauldrons are often used for secret passages, because if you are pushed by a piston while standing in the front of a cauldron, you will fall through it if there is a free space under the cauldron.
