224: AI and Authoritative Sources In my work, I see lots of examples of people accepting what comes from AI as true; we accept whatever it gives us with little effort to confirm it. We should be concerned about this, except for the fact that humans have a very long history of accepting information as Read More
A post for students in network security class: ARP spoofing is a powerful technique used by hackers to intercept and view unencrypted web traffic on a local area network (LAN). This attack exploits a fundamental vulnerability in the Address Resolution Protocol (ARP), which the internet uses to map a device’s IP address (where it is Read More
A blog post for students network security class: Deepfakes represent a modern frontier of digital deception, consisting of counterfeit images, videos, or sounds generated through machine learning algorithms. While these tools can be used for entertainment, they are increasingly weaponized by hackers as social engineering techniques to psychologically influence human behavior. By using technology to Read More
Many high schools, including vocational or trade high schools, offer a range of computer science, digital media, or business applications courses. The specifics of these offerings depend on the history and popularity of the department and the nature of the local business community. If an art teacher is hired who has special skill in digital photography, for example, the school may offer a Read More
159: Multimedia in Schools Generations of students have created presentations using a series of programs that combine text, images, audio, and video (thus the “multi” in multimedia). Many trace the beginnings of this type of educational software to HyperCard and HyperStudio, programs that available were for Apple computers marketed in schools in the early 1990’s. Interest in multimedia grew when video cards, color displays, audio Read More

The paper was presented to the Society of Western Naturalists by its president T. C. Chamberlin. It was very influential to me in 1985, but during a move Read More
161: A Story About School IT Leaders I once coached a technology coordinator who was fond of saying, “I built what they asked for, it they asked for the wrong thing, that is not my problem.” He used it whenever the educators decided the system they wanted wasn’t exactly what they wanted and they asked him to Read More
When I was a student, I was not a strong math student; my lowest grades were always earned in math class. I attributed this to the “D” I earned in math when I was in 4th grade. Despite this, I became a math teacher. My students (and their parents) frequently said I was among the best math teachers they ever had. I attribute this to Read More
165: BYOD and School Networks | RSS.com To minimize the expense of one-to-one initiatives, some schools choose to participate in bring your own device (BYOD) initiatives. This finds schools encouraging students to bring devices they own to school, connecting them to an SSID, and using them for their schoolwork. This can pose several difficulties for IT professionals; security being the most important. Others raise concern about equity as individuals may not be Read More
If you asked someone to design the future of computing, they’d probably picture a sleek brain-computer interface or a 3D spatial reality headset. They probably wouldn’t picture a whiteboard. But tldraw—the team behind the beloved open-source infinite canvas—has been quietly building one of the most radical reimaginings of how we interact with software. It’s called Read More
