Fix VMWare ESXi 6.* slow disk performance on HP b120i controller

Even though this post is fairly dated, I will leave this post online just in case anyone still has an HP ProLiant ML310e or MicroServer Gen8 server with terrible disk performance. It had always been working fine until I started using ESXi 6 and 6.5 on it. For some reason the disk performance was...

How to repair a corrupted/broken Fibaro HC2 Recovery USB Key

Install vSphere client 5.0, 5.1, 5.5 and 6.0 on Windows Server 2003

I don't know why anyone would want to do this in this day and age, but I had a situation where I had to do it, so I'll just write it down here for anyone else who needs this info. Obtain the installer from the ESXi server Ah, and here you already will run into a problem. The webpage won't open! At...

Samba config cheat sheet

This post is mostly for myself, as it contains some example samba configuration code that I use a fair bit on simple samba server setups. Often the most difficult things are rights management and file permission management, and it isn't very hard once you know how to do it. Hopefully this will...

Make permanent swap file in Linux

In Linux you can create a swap FILE that performs pretty much the same function as a separate swap PARTITION, but not with the problem that if later you need to resize some partitions you have to mess around with a partition that's in the way. Yes, I know you can delete it and fix things later but...

Passwordless SSH login with keypair

Mass Effect ring tones and wallpaper

Mass Effect Live Wallpaper for Android Years ago I put some time into sticking some cool live wallpaper I found online on my phone, and I still use it.

Removing hidden hardware (network adapters) from Windows 7

Sometimes hardware devices in Windows 7 are completely hidden in Windows 7. For example, I had a VMWare Windows 7 guest OS running on an ESXi 5.1 server and I did an 'upgrade virtual hardware' step. When I booted up the guest OS, the network connection was called "LAN connection 2" instead of just...

Pin-out of Fritz!Box Y-cable

This is more for myself than for others, but, if you can use it, go ahead. In The Netherlands here, a fair amount of the decent modems sent out for DSL and fiber-to-the-home connections are Fritz!Box routers. These also have a fairly decent phone system built-in that can be hooked up to ISDN or...

Automatic hard drive cleaner built using a raspberry pi

Hey, so we all know the Raspberry Pi, right? It's an awesomely tiny and cheap print board that holds a complete computer on it with a number of interesting connectors and ports. Thanks to a friend of mine in England (thanks Ben!) I was able to get one fairly quickly. So when I got it I just had to...
