  • What does a pointy bit look like to someone who has never seen one ? You have years of experience matching your visual input of the world around you with your tactile experiences, it's easy to forgot how much of our basic knowledge is learned at a young age.

  • Top Apple analyst says MacBook demand has fallen 'significantly'
  • I'm running Windows ARM just fine with parallels on my M1 MBP. Haven't had any issues, even weird legacy software that needs serial drivers works fine. MS did a great job with the ARM version of Windows.

  • Twitter accused of helping Saudi Arabia commit human rights abuses
  • I know we all love to shit on Elon, but read the article:

    Lawyers for Al-Sadhan updated their claim last week to include new allegations about how Twitter, under the leadership of then-chief executive Jack Dorsey, willfully ignored or had knowledge of the Saudi government’s campaign to ferret out critics

  • Anon uses arch btw
  • When have I bitched about Linux? I've had a great experience with Mint, Debian, and Ubuntu. I use Linux, Windows and MacOS on a regular basis.

    Some people just like to complain. Can't fix that.

  • There are generic printer drivers that work fine on windows too. You generally don't need to get the manufacturers bloated driver/utility/update/subscription package. Also that's not really the OS' fault, it's the shitty printer vendors.

  • What's with American firefighters obsession with ventilation before fire control is achieved?
  • Well again, it doesn't say "once the fire is out" It says "once water is applied". The goal is to make the environment more tenable as quickly as possible. We're not as concerned with damage to the property at this point. The main focus is still making things easier for the interior teams by removing heat, smoke, and heated gases. And potentially increase the odds for any survivors. Once we've made the environment safe for firefighters, searched for victims, and put the fire out, then we switch to preserving property.

    We don't want to open doors at this point. Rooms within a structure should be closed/isolated. We want heat/smoke/gases to be removed directly from the structure, not fed further into the structure. But yes, opening windows is a valid form of ventilation, we don't always need to break things. Once the fire is out, interior doors and fans absolutely help.

    Ventilation shouldn't be random, it should be coordinated with the interior attack team(s) so that it occurs closest to where they are working. Yes, improper ventilation can feed a fire and alter its flow path, I don't think anyone would argue that.

  • What's with American firefighters obsession with ventilation before fire control is achieved?
  • I would agree that most of your examples show poor tactics and/or poor training.

    However the first video appears to show proper vertical ventilation. There is a charged hose line into the front door, they are either putting water on the fire already or will imminently.

    I'll cite a UL study on the topic. This paragraph is from the summary, and it highlights the importance of coordinating ventilation with the attack team, but does show that it can greatly improve conditions for the interior team(s)

    Here's a link to the full study, it's a long read but very interesting.

    With that being said, my dept usually doesn't ventilate residential roofs because the reward generally doesn't outweigh the risk. And horizontal ventilation is almost as effective.

  • What's with American firefighters obsession with ventilation before fire control is achieved?
  • Do you have any examples?

    I'm a US firefighter, our department doesn't vent until the engine has water on the fire. And even then we pay careful attention to where we vent. Can't speak for other departments.

    May be a lack of training or inexperienced.
