  Hi, I volunteered for the position of the beloved Open Security Conference mascot. A perfect candidate right from the start, with my name literally being the abbreviated conference name. My (not so) secret dream is to have little plush monkey versions of themself offered as conference swag! I'm into all things security. My team’s clearly purple, just like my bright eyes. I'm frequently seen hugging a flame - the symbol for unconference formats like Open Space.

  It's International Self-Care Day. Yep, that special day that's exactly on July 24th as self-care is a 24/7 topic. Look after yourself. Even if you feel the urge to take care of others first, you are worthy of care, you are worthy to be taken care of first and by yourself. And self-care can show up in multifaceted ways, catering to your very own needs at that moment in time. 1/2

  It's International Non-Binary People's Day! 🎉 Did you know that the date was chosen for being precisely midway between International Women's Day and International Men's Day? Despite the impression this may give, gender is not on a scale at all. Non-binary is an umbrella term and can mean very different things to different people. It's also a way older and more common concept around the world than you might have thought. https://www.selfdefined.app/definitions/non-binary/...

  We're celebrating Global Accessibility Awareness Day! Accessible design helps everyone. We need access to technology and infrastructure also when we're injured, when we're low on mental capacity, when we're in a crisis situation.

  Today is world password day 🔑 Passwords have been used since ancient times and protect humans and assets. But computers get more powerful and adversaries trickier while our brains can't handle the increasing number of long passwords. Therefore there are helpers and alternatives. - Use unique and random passwords with password managers - Use Multi Factor Authentication - Try passkeys Do you like games? https://neal.fun/password-game/ osco [uli] #osco #osco26 #worldpasswordday #passw...

  May is Mental Health Awareness Month. A good reminder that mental health is not always visible, but it is always part of our overall well being. It can show up in different ways, and it is often easy to overlook, both in ourselves and in others. Taking care of it requires intention. That can mean learning more, checking in with ourselves, or creating space where others feel safe to speak openly.
