The Magic of Demos # I remember playing the demo of Indigo Prophecy (known as Fahrenheit in Australia) when I was younger. The demo plays out the intro (as shown above) through to the end of what’s effectively the first level. It was tense and gripping, and felt at the time really innovative insofar as evoking a real sense of panic and urgency. The premise was simple. After coming out of…
I was looking to watch the documentary No Other Land — from the wiki: [No Other land] was recorded between 2019 and 2023 and shows the destruction of a Palestinian community in the occupied West Bank, which had been resisting forced displacement after an Israeli “firing zone” was declared on their land. While not widely available for streaming, fortunately it’s readily available…
Why is it a Problem? # Committing dotfiles to a public git repository is now pretty common. Oftentimes people include their .bashrc without much thought. However, information in one’s bashrc could potentially leak sensitive information — for example: ssh connection aliases that expose server IPs/hostnames, usernames, and potentially private key locations and ciphers AWS account IDs via…

Teams has Chat and Teams tabs, where…

OpenAI API keys in the format sk-<40 case-sensitive alphanumeric characters> A simple regular expression for this would be /sk-[a-zA-Z0-9]{40,}/ i.e., match any string that starts with “sk-” followed by at least 40 alphanumeric characters. GitHub allows regular expression search , but note that if the search is too expensive you’ll get a 5XX response. I noticed modifying it to…

I use Micro Snitch , a neat tool that shows a notification overlay whenever the microphone or camera is accessed. It also logs all access. I noticed whenever I open WhatsApp Desktop on Macos it triggers the overlay notification even though WhatsApp doesn’t use the camera, and AFAIK WhatsApp on the desktop does not use video. Digging deeper, we can use lsof after restarting WhatsApp to see…

You may find it useful for your PS1 to signal if a previous command returned 0 or not. One neat way to do this that doesn’t add clutter is to have your PS1 change colour based on the previous command’s return value. I find that it also works well for scrollback, allowing me to at a quick glance where things went wrong. It can also draw attention to nonzero return values for programs…
