Minecraft: Remove invisible Roots 2 mob spawner

Playing Enigmatica 2 and found a Roots 2 hovel, half into the ground, thatch roof, chests and monsters inside. Cleaned it out, filled it with dirt. Thought it was gone. But monsters kept spawning… Inside the dirt… Opened it back up… Monsters kept spawning… No spawners in sight…

Turns out, there was an invisible entity doing the spawning… Was able to fix it by standing close by and running the following command:

/kill @e[type=!Player,r=10]
Killed entity.barrow.name

After that, no mobs… weird stuff…

Fix IntelliJ Alt Gr not working

I’ve several times had the Alt Gr key stop working while using IntelliJ. On norwegian keyboards, this key is essential in typing e.g. the brackets {} and [], so it not working is extremely annoying. And what increases the annoyance even more, is that, when this happens, the key for some reason stops working in other programs too.

Anyways, this seemed to fix it, on my machine at least, for now:

  1. Go to Help \ Edit Custom Properties
  2. Paste in this line:
  3. Restart IntelliJ

What’s running on port 80 in Windows?

Trying to set up Apache on a server, something is hogging port 80, but very “helpfully” the Resource Monitor just reports “System” with PID 4…

However, some commands found in a StackOverflow answer and its comments were helpful:

netsh http show urlacl
netsh http show servicestate
net stop http

Note: Do not just run these commands blindly and turn off services (in particular you should probably answer N when the last one asks…), but use them to identify what service(s) might be to blame. Then do an intelligent decision on whether the service is needed or not, before you potentially stop it and disable it…

Using SSH keys with BitBucket/GitHub on Windows

Couldn’t get this to work, but now it does, so… time for another “note to self”. 🙂


  • Git, obviously…
  • PuTTY, with puttygen, plink and pageant, to be exact…


  1. Open puttygen.
  2. Load your private key, or generate a new one and save it.
  3. Copy your public key (“Public key for pasting …”) to BitBucket/GitHub/etc.
  4. Open pageant
  5. Load your private key.
  6. Check that the key authentication works by running e.g.
    plink -v git@bitbucket.org
    plink -v git@github.com
  7. Point the GIT_SSH environment variable to plink.exe.

Now, as long as pageant is running with your private key loaded, it should work to clone, pull, push, etc. to/from both private and public repos. E.g. git clone git@github.com:example/some-private-repo.git.

Key here, for me, was the GIT_SSH variable that so many blogs, StackOverflow answers and forum posts failed to mention… Without that set, the plink check did still work, but git clone did not. It just failed with an authentication error. With that variable set it now works perfectly. 🙄🙂👍
