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....

The Grand Seiko Snowflake One of my ideal watches to have would look be like a Grand Seiko Snowflake. The sweeping movement of Seiko’s Spring Drive, the snow-esque dial, dauphine hands, and the blued seconds hand look amazing to me. But since it will never be worth it for me to spend 50k SEK on a watch, I will have to find a cheaper alternative. Luckily, there are a lot of quite similar watches available....

If you are using firefox on linux with a dark theme, unstyled input fields will have black background and white text. Sometimes just white text on white background. According to this bug report it has been this way for the last 17 years. To fix it, pop by about:config and add a new key-value (String): "widget.content.gtk-theme-override": "Adwaita:light". After restarting firefox, things will be as they should be.

So maybe sounds like crap is an overstatement, but compared to what it sounds like on windows / macos / my phone it’s not even a comparison.
