I'm on a flight and the in-flight WiFi blocks all forms of video

Any ideas how it might be doing that, given HTTPS? My best guess is that it could be filtering out known CDN host names that serve video

@simon though technical sophistication varies, the bigger airlines typically they do some detection based on a combination of IPs/hostnames/SNI (for trivial blocking of youtube/netflix etc.) and fallback to tcp session shaping (e.g. terminating/lowering bandwidth for flows after a certain amount of data is exchanged) for everything else.

Perhaps I have simply outgrown some kind of naive idealism, and perhaps some of it is the tendency to view the past through a more generous filter.

But wow is it hard to -find stuff- now. Even stuff I know exists. Hell, even stuff I know I wrote and put out there.

Lost in an ocean of empty words.

Getting to the root of it, I think the thing I miss the most about the old internet was the unstated assumption that the people on the other end of the wire were...people who shared similar interests and just wanted to connect.

I think of all the friends I made, the experiences I had that branched from IRC channels / forums / and even twitter in the later days.

Now the main question I find myself asking of anything that comes across my screen is "what is this trying to sell me?"

I spent large portions of my early career rearranging binary sequences on a chalkboard, and writing assembler for obscure architectures.

There are parts of my brain hard wired to recognize and align protocol stacks from a visual representation of a signal dump.

It's cute that you think you have to explain how computers work to me.

Software request: I'm looking for a tool I can use to manipulate nodes in a graph. Specifically I would like to be able to:

  • Add new nodes to the graph (not a tree)
  • Create multiple distinct edge relationships between nodes (bonus if the tool lets me formalize these edge types)
  • Have nodes contain notes, perhaps be typed
  • Export the graph to a reasonable (text) file format for external processing
  • Explicitly not an image editor or diagram tool.
  • Run on linux / be open source (flexible)

Additional requirements:

  • be able to handle a moderate number of nodes (at least a few thousand)
  • filter nodes by content and/or type
  • calculate subgraphs by edge relationships
  • have a file format that is practical to import into.

A few more notes after answering some questions:

I explicitly want a tool to help me visually modify nodes and edges in a reasonably sized graph.

The modification bit is really key, as it the ability to maintain multiple distinct edges between two nodes.

I want to steer way from diagramming tools because in my experience they don't scale. And I'm not really interested in visualization tools as I already have a workflow for that.

"Note that Recall does not perform content moderation. It will not hide information such as passwords or financial account numbers."

The computer, however, will stop you from recording DRM'd content.

Find it fascinating that when faced with drawing safety and security boundaries, the primary beneficiary is not the owner of the device, or the person using it, but random corporations who control the intellectual property rights.

The system doesn't work for you.

I find it equally fascinating that in order to get anywhere near an integrated computing experience in 2024 we apparently need constant recording and transformer models.

No structured file systems, no permission models, no shared stores, no capabilities - just firehose the display output and hope for the best.
