What I expected After installing Heroes of Might and Magic VI and then starting it through Steam, the game should enter the main menu. What I got The game screen is only black and never enters the main menu. How I solved it Go to My Documents > Heroes of Might and Magic VI. Open ProfileData with your favorite text editor Replace <gfx_Fullscreen2>Fullscreen</gfx_Fullscreen2> with <gfx_Fullscreen2>Windowed</gfx_Fullscreen2> Start game. Game will be in windowed mode, but it’s better than nothing ...

One problem which I encounter time and time again when creating a webpage or applications is matching text color with a changing background color. When creating a GUI you usually create a lot of white boxes with a black text on it, just to get sizes and stuff matching. Then later a designer or customer decides on a theme which affects how that box looks. Most of the time the background and text colors are hand-selected so they match well enough, but from time to time you have to create a box which can change background color on demand, and then you have to have the text color matching to make the box readable. I have done too many slightly different solutions to this problem, so I thought I would write something down here. Since most of the time, text colors are off-white and off-black, the formula should be tweakable to match any given hue. ...

I usually don’t have a keyboard key mapped to caps, since I have my caps mapped to escape instead. However, from time to time it still gets activated. So to save me googling-time, this is the easiest way to turn it off: Alternative 1 xmodmap -e "clear Lock" Alternative 2 #! /usr/bin/env python from ctypes import * import subprocess class Display(Structure): """ opaque struct """ X11 = cdll.LoadLibrary("libX11.so.6") X11.XOpenDisplay.restype = POINTER(Display) display = X11.XOpenDisplay(c_int(0)) X11.XkbLockModifiers(display, c_uint(0x0100), c_uint(2), c_uint(0)) X11.XCloseDisplay(display)

Working with certificates in Java This post contains a mix of java and certificate info. Note that you should definitely use the p12 format in Java. Using other types, like p8, usually end up causing issues in the end. One easy way is by creating a custom trust manager The easiest way of doing this is: (See this link for a code example on stackoverflow Create a custom trust manager with your special certs Create a trust manager with the default certs Create a custom trust manager, which takes the custom and the default trust manager and try them both Another way of doing it would be adding the certificate manually to the cacerts file. Note that you will either need the full certificate chain for it to work, or just the root cert might also work. Note that certs added to the java key store must be in DER-format. See below for converting between formats. When adding with the keytool, you will either need to specify the path manually, or add it with the -cacerts flag to add it to the main key store. The keystore will ask you for password, but the password usually is changeit ...

Sometimes when you exec into a docker container normally, the size of the containers terminal will be much smaller than your real screen, making it not work properly. To solve this you need to set COLUMNS and LINES in the containers env: sudo docker exec -e COLUMNS="$(tput cols)" -e LINES="$(tput lines)" -it docker-container bash
