US gas hits $4 as Trump tells other nations to ‘go get your own oil’ in c/politics@lemmy.world
[–] 5 points 7 months ago

One has to include shortages of fertilizer, and the shortages of fuel that Asia faces now. As other experts point out, those shortages alone will result in demand collapses that will reach back to the US.

Some believe the US has already collapsed. We’re just experiencing the after shocks.

    [Canada] Healthcare Workers With Long COVID Struggle to Find Support and Care in an Environment of Denial (www.medscape.com)
     

    A recent survey among Quebec healthcare workers demonstrated that the cumulative risk of developing long COVID from an acute infection is 17% and increases with each infection. The estimated prevalence of long COVID in this population was 5.6%. Other research places the global risk as high as 40% among healthcare workers who have contracted an acute SARS-CoV-2 infection.
    …

    Nevertheless, many healthcare workers still don’t believe that long COVID is real, despite dramatically disabling symptoms in people with no preexisting risk factors. “The me before and the me now are such opposites,” said Pinard. “I would swim three mornings a week before going to the office. I was running 40 km. I was traveling every second week. Now I leave my house only every 2-3 months….I was where I was supposed to be [with COVID vaccination]. I was in good health. I wasn’t depressed; I wasn’t anxious.”
    …

    Hulme and other interested parties have tried to help build the infrastructure needed to provide care for patients with long COVID, but they have faced many barriers. Although the condition shares many features with fibromyalgia, myalgic encephalomyelitis/chronic fatigue syndrome, and postural orthostatic tachycardia syndrome, guidelines for those conditions could not mention long COVID by provincial government decree. “There are many, many political reasons as to why [long COVID] should not become a big deal,” said Hulme. “There are still little pockets of money for research, but they are very small.”

    Texas has power outages for days at a time. People get rocked by astronomical utility bills. Also, Texas has boil water advisories for big population centres in one of the richest states in the US.

    There’s nothing to covet here. It’s an embarrassment.

    Uh oh. The dreaded polar vortex may be making an appearance very soon (www.cbc.ca)
     

    Well, get ready to hear more about it. Forecasters say parts of Western and Central Canada are about to feel the effects of the phenomenon that brings frigid weather in the coming weeks. And it could move to Eastern Canada.

    “The European [model], the latest one, is looking like a pretty impressive cold pattern setting up,” said Judah Cohen, a climatologist at the Massachusetts Institute of Technology (MIT).

    “The cold is going to slide down east of the Rockies … you'll hear about Calgary, definitely Winnipeg.”

    Brace yourselves and be careful. A reminder from 2024:

    The number of amputations due to frostbite in Edmonton reached 110 last winter, the highest level in more than a decade, according to new data obtained by CBC News.

    But Calgary marked its second consecutive winter of declining frostbite amputations, counting roughly one-third of Edmonton's procedures last fiscal year.

    Maybe most of society doesn't have much critical thinking because those who get those "critical thinking" genes go crazy from overthinking things and therefore fail to pass on the genes. in c/showerthoughts@lemmy.world
    [–] 12 points 11 months ago

    I’d say you are confusing critical thinking with anxiety. Critical thinking is a deliberate exercise that I choose to engage in, and I might be able to do for a certain period of time. I’d suggest that critical thinking is an investment of time and energy to really understand an issue, how it’s framed, how to re-frame it. At the highest levels, critical thinking will eventually lead to where you stand on an issue, and what scenarios change your standing.

    But anxiety is something I don’t mean to engage in, and might not be able to stop. I’d agree it’s a disruption of critical thinking. It’s either a response to stress, or perhaps a force is pushing you to anxiety to break down your OODA loop (Observe, Orient, Decide, Act) and render you less effective on the field you’re playing in.

    #solved

    EDIT: 2025-10-25 at 11h29 - I deleted the Content-Security-Policy and PieFed displays images as expected.

    Reasoning

    So after crawling through some very old Reddit posts, I came across other self-hosters discussing their new found interest in Security Headers from 5 years ago (dated, yes). Among the comments was a post by pentesticals (glorious):

    quote

    Don't stress about security headers and CSP. These are there to help provide additional protection against client-side issues which may or may not be present.

    These will not have any direct impact on your services you expose, rather they aim to be a last resort to protect your browser in case an attacker tries to exploit existing vulnerabilities such as a Cross Site Scripting - but not having these does not increase the risk of your server being compromised.

    Use Nessus Essentials for scanning your services and have fun.

    https://www.reddit.com/r/selfhosted/comments/mpzl8f/any_recommendations_for_security_scans/

    I use Caddy and I can indeed see the security headers that involve CSP. How should this setting be amended?

    For what it's worth I looked over the "Using Caddy as reverse proxy" for Lemmy, and I notice that they just don't use the Content-Security-Policy option at all. I'm wondering if I should simply delete this Header for PieFed.

    https://join-lemmy.org/docs/administration/caddy.html

    Security Headers

    (security_headers) {  
  header {  
    Strict-Transport-Security "max-age=31536000; includeSubDomains"  
    X-Content-Type-Options "nosniff"  
    X-Frame-Options "SAMEORIGIN"  
    Referrer-Policy "no-referrer"  
    X-XSS-Protection "1; mode=block"  
    Permissions-Policy "camera=(), microphone=(), geolocation=(), accelerometer=(), autoplay=(), fullscreen=(), gyroscope=(), interest-cohort=(), magnetometer=(), payment=()"  
    -Server  
    -x-powered-by  
  }  
}

    Displaying Images From View Community Solved (kopitalk.net)
     

    Sorry, new guy here.

    So about images, on my desktop browser, when I click just on the thumbnail to the side, I'm expecting the image to display. But the image loading graphics just keep looping without any image.

    If I click the post, the image typically displays as expected.

    On Voyager, tapping the thumbnail loads the image to the screen as expected.

    PieFed Email Error (kopitalk.net)
     

    Hello!

    I wanted to move away from Reddit and started with a Lemmy instance for a few days. But, I kept on bumping into these mentions about PieFed and got curious. I figured since I just started, no harm in just spinning up PieFed. That, and once I saw Voyager was able to work with PieFed, it just seemed like a no brainer.

    I'm so very impressed, I'm just exploring everything, checking out settings, and adding new communities.

    That said I probably did something wrong in the process. I input the settings for email in .env.docker. As soon as I did, error emails arrived in batches of 5-8 at a time. I tried making sense of it myself, but I got stuck. Would anyone kindly take a look and point me in the right direction?
