  • Civil engineer with a number of courses in building science (aka this).

    Can’t tell for sure without seeing what kind of insulation it is, but there are a few factors.

    First, as other people have mentioned, having temperature gradients cause moisture issues. Typically, in modern construction in cold weather climates like Canada, we install a single waterproof layer. Cold weather, this goes inside of the insulation (between the insulation and the drywall), and in hot weather places, it’ll be installed outside the insulation.

    Explanation why

    The reason (simplified) for this basically boils down to hot air holds more water. As the air cools, it drops off the extra water it can no longer carry on nearby surfaces. You want to make sure hot air stays hot, and cold air stays cold. If you allow air that is hot to cool down, it will create moisture.

    My understanding of the houses this is being done in, there is no vapour barrier, meaning damp+ moisture can accumulate.

    Second, new houses in NA have a “minimum air exchange”, which is a specific amount of air that needs to move through the house within a given time frame, typically air changes per hour (ACH rating). This is usually accomplished by means of a central heating/ductwork units, and bedrooms are generally somewhere around 4-8, meaning all the air in the bedroom should be refreshed 4 to 8 times per hour. My understanding of many of these houses is that there is not central air system. Before the insulation, it is likely that small gaps or holes in the walls/exterior siding were sufficient to allow enough air to move through, however that air slows down when there is insulation sprayed into the cavities. Any slowdown will exacerbate moisture problems, as still air is bad. More air exchanges also would allow the house to dry out more, as evaporation would help.

    Those are the general situations that would likely be a problem.

    In this case, from reading the article, it seems like she has a hole in her roof, which is either new or was not caught by the installers. ANY source of water ingress would cause mold problems. The issue here is that previously, it is likely that the water trickled down the inside of the cladding (likely brick), and out at the base of the wall. Once you add insulation to that cavity, it’ll hold water and cause mold problems. Seems like a shitty spot to be in.



  • Really? Every single item is wrapped in plastic at your grocery store? No loose apples, cucumbers, potatoes, or leafy greens?

    If those are all wrapped in plastic, then look for what options have less plastic. Avoid double wrapped items, for example, or anything marketed as single servings.

    I feel like none of this is that hard to come up with. It’s unfortunate you don’t seem interested in an actual conversation. Hope you have a better rest of your day.


  • You should blame them and still choose options with less plastic where possible? I don’t see where this idea of black and white, one or the other comes from

    Where it’s feasible given your financial and geographical means, avoid food wrapped in plastics, foods shipped from far away, and meats. Not every single item in the store comes in plastic. It will require adjusting your habits, for sure.

    No need to demonize anyone for not being able to if it doesn’t work, but every time you choose something better, it’s an incremental step forward.

    At the same time, send an email or phone call to the grocery store manager. Write to your local politician and push for laws regarding stricter use of plastics, more comprehensive recycling programs, or funding and grants for local farmers.

    Simply being angry online and not changing your own habits or lobbying for change isn’t actually improving anything.


  • Not the person above, but Corporations are built around the idea of selling something. The biggest way to reduce your environmental impact is to not buy shit. Doesn’t matter if the shit is eco friendly, more shit means more emissions.

    Corporations don’t pollute for shits and giggles. They pollute because they want to make stuff for us to buy. Shell doesn’t just make pollution, they pollute on the way to producing gas.

    If we cut back on how much gas we use, Shell pollutes less because they have less gas to sell.

    That doesn’t absolve Shell of their role in chasing profits over environmental protection, and there’s plenty of space for demanding better and holding them accountable, but acting like these corps pollute just cuz is disingenuous. They pollute because we want shit.



  • You’re looking at the original article. This whole series of comments has been spawned off a discussion about a different case, in which the person did join the organization, then let his license lapse.

    In the original, I agree. He never required a license because of their own regs( though it appears that also means he couldn’t call himself a professional engineer, so the title itself is protected, he was just exempt from needing the license to do the industrial work he was doing). He is then totally within his rights to use that knowledge and pass himself off as a subject matter expert in the same field he worked for X years, and the board just got pissy. Glad it was overturned for him.


  • I’ve used the system pretty regularly. To be fair, I live in a small city (150,000) within the golden horseshoe, so definitely better care compared to many throughout rural areas.

    In the past few years I’ve had the birth of a child including all the various follow ups and shots, a stress test, blood work to rule out several heart issues, a halter monitor test, an ultrasound of my heart, three sets of baseline blood work, and four family doctor appointments.

    The biggest fee at each was parking.

    I don’t disagree we have tons of room for improvement. Our contributions each year (ie personal amount of taxes we pay for healthcare in Ontario) have not been sufficient to keep up with the growing and aging population. We desperately need greater cancer screening and diagnostic services, as prevention and early detection can save billions in future chemo/rad or operations. Rural areas and family doctors need a rework, as many people are without one due to fewer and fewer docs entering that field.

    That said, I would never take the US system over Canadas. The enormous stress illness would place on a family doesn’t seem worth it for the meager tax savings, and the low wait times seem to only be avoided in the US system by paying out of pocket, which is not feasible for many.


  • When it comes to titles like this that are considered protected, it is actually how they work.

    In your example, he isn’t allowed to use that title in the new state until he’s joined their organization (or they have an agreement with his original state)

    As an extreme example for why the timing does matter, If he was licensed properly for 1 year, then let it lapse but continued to do design work as an engineer for 25 years, and then relicensed himself for one last year before retiring, the work he did during that period of being unlicensed isn’t covered, and the board of engineers would go after him for that.

    For what it’s worth, there are specific provisions in the laws to allow retired people to continue using the title P.Eng with a “Retired” tag added onto it.



  • This is not true. I can call myself a doctor a lawyer or a cop or anything like that and it is protected speech so long as I am not attempting to perform the professional duties of that job

    It actually is true, unless MN has weird rules compared to other states. I’m not a lawyer, but the code here, sec. 326.02 seems pretty clear.

    or to use in connection with the person’s name, or to otherwise assume, use or advertise any title or description tending to convey the impression that the person is an architect, professional engineer (hereinafter called engineer), land surveyor, landscape architect, professional geoscientist (hereinafter called geoscientist), or certified interior designer, unless such person is qualified by licensure or certification under sections 326.02 to 326.15.

    You actually can’t call yourself a professional engineer if you’re not - theres several lrgal cases where i am that are ongoing due to people calling themselves engineers while being realtors, for example, and trying to use the title to advertise (IE John Doe, P.Eng), which is not allowed.


  • If your argument is that you’re an expert, then you need to have the credentials you claim to have. Anyone can show the faults in a design, but he’s explicitly doing novel calculations and analysis - ie not just reviewing someone else’s work.

    Now that being said, it looks like he never needed a professional license as he fell under an exemption, in which case I feel like they shot themselves in the foot. He’s got previous experience doing the same thing he’s examining - hydraulics and fluid flow analysis. Regardless of his status as “professional engineer”, his previous experience sould qualify him to testify.




  • Women are definitely capable of doing super endurance events, but they are not the equivalent of men on setting records for any race I’ve found.

    One called “backyard ultra”. Basically you do a lap of 6.7km each hour until everyone else drops out. World records are all men by a long shot - https://backyardultra.com/world-rankings/

    Fastpacking, a slower event than the backyard ultras, involve hiking/jogging through hiking trails while carrying what you need. Definitely slower pace, and I’d argue closer to what I’d imagine with a long, days-long hunt would be like for ancient tribes. FKT, or fastest known times, are often found at this website. Looking at all the times, men carry a significant lead in both supported (ie someone else carries your food/water/sleeping gear), and unsupported. As an example, look at the Appalachian Trail – https://fastestknowntime.com/route/appalachian-trail

    Even the RAAM shows solo male records much faster than women: https://www.raamrace.org/records-awards

    The thing the article failed to mention (and the thing I think is key) is that women excel at doing these things, typically, with less energy burnt both during and after the races. Women on the whole are smaller, and tend to have better insulin responses (as mentioned in the article) which means their blood sugar stays consistent during exercise and after. Consistent blood sugar means less wasted energy. Larger heart and lungs, combined with higher type 2 muscle fibres compared to women’s type 1 means, again, less wasted energy and more efficiencies. Less muscle damage, as mentioned in the diagram, means less to repair, which means more saved energy. In a hunter/gather society, this saved energy can be significant.

    With modern access to food, that evolutionary advantage seems to vanish, and the article doesn’t even touch on it.


  • I can speak to this as I’m just going through it now.

    I’m a young male in good health. I started having weird heart palpitations randomly starting last year. Had them four times, but they normally go away after 20ish mins. GP reviewed me, said it seemed fine, but to go in to ER if anything about them changed (ie more frequent, more intense, lasted longer).

    Last friday they went on for an hour, so I went in. Entered at 11am.

    Was triaged within 15mins, including an ECG. Once they confirmed it wasn’t an active heart attack, I sat in the waiting room for two hours. I then saw a doctor, got a chest X-Ray, and bloodwork taken within 45mins. I proceeded to sit in the room hooked up to the vitals monitor for four hours while they ran my bloodwork, and the ER doc came back. He sent me a requisition for a cardiologist and told me to take aspirin until I saw the specialist.

    I saw the Cardiologist on Wednesday, and he’s explained he’s not concerned given my lack of other risk factors. He’s now sent me over for an ultrasound and 36hr halter monitor next Monday. He said unless something weird comes back or he wants another test, he won’t see me again, and I should follow up with my GP 2 weeks after I finish the halter monitor.

    So within 3 or 4 weeks I had a full range of tests done, and my biggest expense was $7.50 parking for the 30min cardiologist appointment, which I was actually unironically complaining about to my wife last night.
