  • Totally fair, awareness is a big thing too, fire crews are professionals so I do think they made the best choice with what they were given, every firefighter I’ve met will absolutely do an assessment before doing anything.

    Don’t know their situation, were they just told vehicle fire not lithium fire? Maybe more lithium specific crews/equipment in the future, maybe battery compartments that can help contain? (As I said, with lithium batteries I’ve worked with in the past, pressure vessels, if they went off it was at least contained to inside that, they’d vent gasses still but at least the threat of fire was minimised)


  • There’s already tools to deal with lithium fires, class D fire extinguishers, sand and vermiculite. When I worked heavily with lithium non-rechargables we had lithium disaster plans for fires, explicitly in that was alerting fire fighters that it’s a combustible metal fire so they can react accordingly, those fires need to be smothered afaik, water was a big no no.

    Generally though, the plan was, escape and enforce a quarantine zone because primary cells give off nasty stuff, if you can drop it in a bucket of vermiculite if it’s out of the containment vessels and pretty much let them do their thing. Then once it seems like it’s done, wait more time to make sure it’s actually safe with 30 minute gas tests, then package them for safe transport.












  • Could use Polars, afaik it supports streaming from CSVs too, and frankly the syntax is so much nicer than pandas coming from spark land.

    Do you need to persist? What are you doing with them? A really common pattern for analytics is landing those in something like Parquet, Delta, less frequently seen Avro or ORC and then working right off that. If they don’t change, it’s an option. 100 gigs of CSVs will take some time to write to a database depending on resources, tools, db flavour, tbf writing into a compressed format takes time too, but saves you managing databases (unless you want to, just presenting some alternates)

    Could look at a document db, again, will take time to ingest and index, but definitely another tool, I’ve touched elastic and stood up mongo before, but Solr is around and built on top of lucene which I knew elastic was but apparently so is mongo.

    Edit: searchable? I’d look into a document db, it’s quite literally what they’re meant for, all of those I mentioned are used for enterprise search.




  • Why does that image only have the sun and the rebel from Canadian media? Both are given more credibility than they deserve, the rebel in particular has history, bunch of white supremacists and alt right personalities were or are still involved, publication absolutely stokes hate and fear.

    Edit: I’m still at a loss, why those? The Globe and Mail, McLean’s, The Toronto Star, National Post, CBC all have better reputations domestically (though natpost and the sun are a circle these days and most print media is owned by American Hedge Funds so…), far more likely to actually get the news instead of opinion masquerading as news in one of those.
