  Dog walkers. I love haze, and the compression of a long lens. The silhouette caught my eye initially. The echo on the the further beach was a bonus. #Photography #SouthAfrica #BettysBay #Seascape #Beach https://www.deviantart.com/africanobserver/art/1357888463

  A key cutting machine in a shop along Koeberg Road. The sparkle of the old keys and filings caught my eye. I'm not sure the photo captures what I thought I saw. #photography #capeTown #SouthAfrica #handcraft #workshop https://www.deviantart.com/africanobserver/art/1331141240

  Helping a school counsellor set up some issue reporting forms. @liberaforms has the smoothest, safest, implementation for setting up public/ private keypairs I have used. With a great verification step! A backup is not tested until you have restored it! Another step to #DigitalSoverieignty

  RE: https://mastodon.social/@grant_h/116523045836241095 I have created a secure @liberaforms form to source data from a couple of educational email lists I'm part of.

  #Python community question. What motivated the generally wise and insightful devs to make mutable parameters hold the history of every call? Given: class h(): def __init__(self,x,y=[]): self.instanceY = y self.instanceY.append(x) def __repr__(self): return(f"{self.instanceY}") h1 = h(1) print(f"{h1=}") h2 = h(2) print(f"{h1=}, {h2=}") Who would expect this: h1=[1] h1=[1, 2], h2=[1, 2] I get...

  Poll about #school #counsellors and #dataPRIVACY in #education Do your counsellors ensure that private and confidential client data is private from the moment of capture onwards - ie on the device, on the network, and in storage? Does your institution take data privacy seriously enough to spend money and change behaviour? (Note - secure is NOT private. Any use of cloud storage where the data is not deliberately encrypted before storing is likely to be compromised) Please boost for reach.

  #Higraph progress! Still got lots to do, but hyperEdges can now be saved & loaded in modified #graphml files. The "model tree" on the left highlights items in the graph on the right. I can see "minimum viable product"! The #hyperedge structure is both graphically and algebraically accessible. I'm not aware of anything else that does this, pretty certainly not in #Python #graphTheory #VisualFormalism
