TED Talk: The riddle of experience vs. memory

We tend to think of memory the same as an audio-visual recording of the events in our life. Unfortunately, it is not. Memory captures snapshots which influence what we recall later. So a relatively good experience with a particularly bad ending can bias memory to recall the whole as bad. If the below video does not… Continue reading TED Talk: The riddle of experience vs. memory

Twexports

Data portability is good both for users and systems. But I like being able to export my data for another reason: search. Some times I want to build on an old conversation.

The conversion process creates an import file using the WebCT SourcedId.Id as the OrgCode. The first time the OrgCode is used, it creates a course. The next and subsequent times, it duplicates… Continue reading OrgCode Duplicate Filter

Scrambls encrypts social media posts and lets users specify exactly who can see them, across all social media sites. The user can form groups from friends and family, going as broad as everyone with a Gmail account down to a specific colleague or even those who know a certain password. Everyone else (including the social… Continue reading Scrambls
