  • Yeah, hypercapnia is fucked. I’m actually testing a small CO2 gas generator (literally just citric acid added dropwise to sodium bicarb with an acid trap and a dehumidifying stage) as a means to kill pests on houseplants and did some reading on the symptoms to be safe. It is unpleasant. It’s not the worst death I could imagine, but it’s shit.

    As an aside, the way that CO2 kills bugs is interesting. Basically, the excess CO2 (in the range of 10-80,000 ppm) causes their spiracules (i.e. the little holes in their exoskeletons they use to breath) to stay open. This causes them to lose moisture until they die of dehydration (usually in a matter of hours). All this happens long before they asphyxiate or suffer from any sort of acidification from the CO2. It’s a bit fucked up, but all other means of getting rid of the pests on my partner’s houseplants have failed.


  • It’s a shame that nobody has produced a molecular test cheaply enough for free distribution yet. The fact that you can get PCR quality tests entirely at home makes the antigen tests a non-option for me and mine. They’re too expensive to recommend to most people, however. The ones I’ve been using are $25 per test, and you also have to pay $50 for the reusable test reader. That’s way cheaper than they used to be (Lucira COVID tests were like $75 a pop, and the fact that the entire unit was single use was terrible from a waste perspective), but it’s still just not good enough.

    EDIT: lmao, Pfizer bought Lucira and is now selling combo COVID+flu tests with the same single-use tester. I wish they had converted to a reusable central unit with disposable tests like most other molecular COVID testers…

    EDIT: yikes, the Lucira combo tester might be giving false positive results for the flu. Dunno if this Amazon review is accurate, but it’s certainly concerning:

    Here is said Amazon review

    This is one of the first combo tests for flu and COVID-19. By training, I am a microbiologist and infectious disease epidemiologist. Thus, I ordered some of these new tests to see how well they worked and how easy they were. As additional background, I have run infectious disease laboratories and have designed diagnostic assays. Thus, having an at-home test is always a nice luxury.

    The instructions were easy to use. I will note that when you put the vial in the reader, do not push it all the way down, as that is when the test will actually start. So be sure to mix your swab in the buffer (purple liquid) for the appropriate time and then cap the viral and push down.

    I ran the first test (far left in the picture) and within 10 minutes it came up as positive for influenza B. Currently, in the US, in my age bracket, flu B makes up about 17% of diagnosed cases, so the biological rationale is that this could be real. However, I was asymptomatic and was only running the test to see how easy it was to run. I then retested on a rapid antigen test that included SARS-CoV-2, Flu A, Flu B, and RSV. These unfortunately are not available in the US but I had some left over from a trip to Europe. That was negative for all of those pathogens. Since these molecular tests have a lower limit of detection (meaning they can detect small amounts of viral nucleic acid compared to rapid antigen tests). However I did buy four of the Lucira tests, so I ran another one (far right in the photo). That came back negative for all of the pathogens.

    This is highly concerning. Given no diagnostic test is perfect, had I only had one test on hand and no way to corroborate the first test result I would have been isolating thinking that I had influenza B. When in actuality, it seems most likely that the first test was a false positive result. Looking at the Instructions for Use on the FDA website, it shows for Flu B, that in 364 PCR negative samples, 1 was positive on the Lucira test. So there is always a possibility that you test results may not be accurate. However, it was curious that this happened the first time I used this assay.

    I would personally avoid this product. I have been using many of the at-home tests for the past few years and have NEVER had a false positive. Thus, this has put much doubt into the results and the technology behind this product. This is the only molecular combo assay for SARS-CoV-2 and Flu on the market at this point, but others will be released shortly and I would interpret these results carefully. Really, I would love if they refunded me the cost of one test, but I won’t hold my breath there

    The article says that he refused the prize because he felt that he hadn’t earned it. He felt that the prize should be awarded to Richard Hamilton who developed the theory Perelman used to fully solve the Poincaré Conjecture. I’m not saying it was the wisest or easiest solution. I was only trying to express my opinion that I find his adherence to his strong principles admirable.

    I’m absolutely not advocating for anyone to turn down a million dollars. For anyone in a position where they can just, like, get a million bucks, take that shit and live a happier life!

    Also from the article:

    The writer Brett Forrest briefly interacted with Perelman in 2012. A reporter who had called him was told: “You are disturbing me. I am picking mushrooms.”

    I enjoy this man’s focus and determination. I feel like the world probably missed out on good things when he left academia, but I can’t blame the dude when I saw why he refused a million dollars for solving the Poincaré Conjecture. He seems like a person with very strong principles.



  • Ugh, I hate ChatGPT. If this is Bash (which it is, because it’s literally looking for files in a directory called ~/.bashrc.d), then it should god damned well be using syntax and language features that we’ve had for at least twenty fucking years. Specifically, if you’re writing for Bash (and not POSIX shell), you better be using [[ ]] rather than [ ]. This wiki is my holy book I use to keep the demons away when writing Bash, and it does a simply fantastic job of explaining why you should use God damned double square brackets.

    ChatGPT writes shitty, horrible, buggy ass Bash. This is relatively decent for ChatGPT (it even makes sure the files are real files and not symlinks), but I’ve had to fix enough terrible fucking shitty AI Bash to have no tolerance for even the smallest misstep from it.

    Sincerely, A senior developer who is known as the Bash wizard at work.

    EDIT: Sorry, OP. ChatGPT did not, in fact, write this code, and I am going to leave my comment here as a testament to what a big smelly dick I was here.


  • My partner and I have this thing where we ask each other if we are the other person’s x, where x is something ridiculous, cute, grotesque, or profane. For example, I once asked my partner if I was her gutter-bloated corpse, to which she, of course, answered in the affirmative.

    I’ll soon find out if I am actually a tasselled wobbegong carpet shark in the eyes of my partner.

    As an aside, I asked the corpse thing after reading this delightful line from one of my very favorite books:

    “Body found floating by the docks,” Glokta breathed, “bloated by seawater and horribly mutilated… far… far beyond recognition.”





  • what the fuck

    What is it with this fucking man and disgusting dead animals‽ Like, this was before the brain worm started driving ffs! I really thought the brain worm was the reason this dude was so fucking crazy, but apparently not! It must be Rosemary Kennedy’s ghost, tormenting the family for what they did.

    EDIT: Jesus I just can’t get over this. They’re dead man you don’t have to fuck with them just leave them alone and enjoy your time on the beach with your family or in Central Park throwing dirt clods at the drifters like you want to

    just don’t fucking touch the dead animals anymore

    EDIT: I’ve done some more research and have learned a few things

    1. the US education system sucks at telling recent history because i just learned about RFK’s assassination
    2. maybe he’s all crazy and fucked up because his uncle and dad were assassinated when he was 9 and 14
    3. maybe he’s all crazy and fucked up because he was doing fucking heroin from the age of 15 (jesus what does that do to a developing brain)
    4. maybe he’s all crazy and fucked up because his family was probably neglectful (and possibly abusive) as hell because he certainly acted like a neglected and spoiled teenager (he was suspected of committing a bunch of crimes and shit with other kids)

    like, I just want to understand what his fucking problem is. It was easy when it was the brain worm. I view him as a bit dangerous which is probably why I’m latching onto this and trying to understand his motivations. Dangerous people are easier to handle emotionally if you know why they’re dangerous and what they want.






  • I’ll second this, I think it’s impressive that you were able to get any sort of photo. I am decidedly not a birder, but I’ve tried taking long distance pictures of moving objects with a fairly extreme telephoto lens and I was dreadful at it. I’m even more amazed that you weren’t using burst mode.

    I was going to ask what your aperture was, but I’m guessing it’s f/11 after looking up the lens. Canon made a crazy thing! I like it, and I hope other manufacturers take note. I’d especially like it if Sigma or Tamron made a compact 800mm prime lens.



  • Nah, the slow hop-hop-hop is like a jog. Mustelids can fucking zoom if they’re in danger or after prey. Like, even dopey-ass domesticated ferrets can get going pretty damn quick when they’ve been hurt or feel threatened. Nobody has posted what species of otter attacked this lady, but river otters can reach speeds of 47 kph (29 mph) on land. Sea otters are slow and fat, but these weren’t sea otters.

    You aren’t outrunning a pack of otters in a sprint. It’s no question that you could outrun them over a long distance, but mustelids are zoomy little fuckers.

    (note that I like mustelids and had 4 ferrets, so please don’t mistake my tone as being sour on them)

    EDIT: holy shit, ferrets can be bred and trained to run at like 22 mph. That’s insane!
