Ross Ulbricht told her about Silk Road, but then later said he had sold the website to someone else, without really doing that.

Obsidian (software) Updated 2025-07-16
Good:
- WYSIWYG
- Extended-Markdown-based
- help.obsidian.md/Getting+started/Sync+your+notes+across+devices they do have a device sync mechanism
- it watches the filesystem and if you change anything it gets automatically updated on UI
- help.obsidian.md/links#Link+to+a+block+in+a+note you can set (forcibly scoped) IDs to blocks. But it's not exposed on WYSIWYG?
Bad:
- forced ID scoping on the tree as usual
- no browser-only editor, it's just a local app apparently:
- obsidian.md/publish they have a publish function, but you can't see the generated websites with JavaScript turned off. And they charge you 8 dollars / month for that shit. Lol.
- block elements like images and tables cannot have captions?
- they kind of have synonyms: help.obsidian.md/aliases but does it work on source code?

According to jercos the transaction was finalized over IRC chats. Jercos was 18 at the time of the transaction.

Jena SPARQL hello world Updated 2025-07-16
They have a tutorial at: jena.apache.org/tutorials/sparql.html
Once you've done the Apache Jena CLI tools setup we can query all users with Full Name (FN) "John Smith" directly fom the rdf/vcard.ttl Turtle RDF file with the rdf/vcard.rq SPARQL query:and that outputs:

--------------------------------- Ollama Updated 2025-07-16
Ollama is a highly automated open source wrapper that makes it very easy to run multiple Open weight LLM models either on CPU or GPU.
Its README alone is of great value, serving as a fantastic list of the most popular Open weight LLM models in existence.
Install with:
curl https://ollama.ai/install.sh | shOn P14s it runs on CPU and generates a few tokens per second, which is quite usable for a quick interactive play.
As mentioned at github.com/jmorganca/ollama/blob/0174665d0e7dcdd8c60390ab2dd07155ef84eb3f/docs/faq.md the downloads to under The file:gives a the exact model name and parameters.

react/ref-click-counter.html Updated 2025-07-16
Dummy example of using a React
ref This example is useless and to the end user seems functionally equivalent to react/hello.html.It does however serve as a good example of what react does that is useful: it provides a "clear" separation between state and render code (which becomes once again much less clear in React function components.
Notably, this example is insane because at:we are extracing state from some random HTML string rather than having a clean JavaScript variable containing that value.
<button onClick={() => {
elem.innerHTML = (parseInt(elem.innerHTML) + 1).toString()In this case we managed to get away with it, but this is in general not easy/possible.

In this example we will initialize a quantum circuit with a single CNOT gate and see the output values.
By default, Qiskit initializes every qubit to 0 as shown in the qiskit/hello.py. But we can also initialize to arbitrary values as would be done when computing the output for various different inputs.
Output:which we should all be able to understand intuitively given our understanding of the CNOT gate and quantum state vectors.
