  • It very definitely was 😅 The way that company used the satellite network was cool, don’t get me wrong. They would use it to push content out to all their stores with multicast which was really efficient with bandwidth. I loved it for that, but I hated interacting with it over unicast in any way, shape, or form. Horses for courses, as they say.




  • My pain tolerance for shitty input methods has been permanently warped after experiencing psychic damage from using Teamviewer to connect to a system over a very flaky HughesNet satellite link. I was working for a vendor that supplied a hardware networking box to a stupid retail company that sells food and shit. I just wanted to ssh to our boxen on a specific network so I could troubleshoot something, but the only way I could get to it was via putty installed on an ancient Windows XP desktop on the same network as our box that could only be accessed with Teamviewer. My favorite part of that was that the locale or something was fucked up, so my qwerty keyboard inputs were, like, fucking transformed into azerty somehow?? The Windows desktop was locked down and monitored to a tremendous degree, so I couldn’t change anything. The resolution was terrible, the latency was over a second, and half of my keyboard inputs turned into gibberish on the other side.

    Oh, and I was onsite at that same company’s HQ doing a sales engineering call while I was trying to figure out what was wrong. I spent 5 days sitting in spare offices with shitty chairs, away from my family, living that fucking nightmare before I finally figured out what was wrong. God damn, what a fucking mess that was. For anyone reading this, NEVER WORK FOR GROCERY/DRUG STORE IT. They are worse than fucking banks in some ways. Fuck.

    EDIT: also, I asked ‘why Teamviewer’ and the answer was always shrugs. This was before the big TeamViewer security incidents, so maybe they thought it was more secure? Like, at least they didn’t expose RDP on the internet…


  • Having been in this situation (the only binary I could use was bash, although cd was a bash builtin for me), echo * is your friend. Even better is something like this:

    get_path_type() {
        local item
        item="$1"
        [[ -z "$item" ]] && { echo 'wrong arg count passed to get_path_type'; return 1; }
        if [[ -d "$item" ]]; then
            echo 'dir'
        elif [[ -f "$item" ]]; then
            echo 'file'
        elif [[ -h "$item" ]]; then
            echo 'link'  # not accurate, but symlink is too long
        else
            echo '????'
        fi
    }
    
    print_path_listing() {
        local path path_type
        path="$1"
        [[ -z "$path" ]] && { echo 'wrong arg count passed to print_path_listing'; return 1; }
        path_type="$(get_path_type "$path")"
        printf '%s\t%s\n' "$path_type" "$path"
    }
    
    ls() {
        local path paths item symlink_regex
        paths=("$@")
        if ((${#paths[@]} == 0)); then
            paths=("$(pwd)")
        fi
        shopt -s dotglob
        for path in "${paths[@]}"; do
            if [[ -d "$path" ]]; then
                printf '%s\n' "$path"
                for item in "$path"/*; do
                    print_path_listing "$item"
                done
            elif [[ -e "$path" ]]; then
                print_path_listing "$path"
            printf '\n'
            fi
        done
    }
    

    This is recreated from memory and will likely have several nasty bugs. I also wrote it and quickly tested it entirely on my phone which was a bit painful. It should be pure bash, so it’ll work in this type of situation.

    EDIT: I’m bored and sleep deprived and wanted to do something, hence this nonsense. I’ve taken the joke entirely too seriously.



  • 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


  • I used Google maps to get these values. I’m using Google’s estimated walking distance and will also include Google’s estimated walking time.

    • Convenience store
      • Distance: 800 m
      • Time: 11 minutes
    • Chain supermarket
      • Distance: 1.1 km
      • Time: 15 minutes
    • Bus stop
      • Distance: 230 m
      • Time: 3 minutes
    • Park:
      • Distance: 450 m
      • Time: 7 minutes
    • Big supermarket (Walmart)
      • Distance: 1.7 km
      • Time: 23 minutes
    • Library
      • Distance: 2.7 km
      • Time: 37 minutes
    • Train station (local light rail)
      • Distance: 3.1 km
      • Time: 43 minutes

    I’m in Utah somewhere south of Salt Lake City (the state capitol). The numbers aren’t great, but they’re far better than some places I’ve lived here. As a kid, I remember biking for 20+ minutes to make it to a small supermarket.

    EDIT: as others have said, my paths can be quite bendy at times, but it’s different than many suburbs in the US. Salt Lake City (and, by extension, most of the valley that it’s in) is built on a fairly rigorous grid system. We have lots of straight roads with large blocks (in some cases, it can be 1-2 km between lights and crosswalks). We don’t have too many ratfucked suburban mazes, so the walkability problem here is primarily due to sprawl and a dearth of crosswalks.




  • 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.


  • I’m guessing it’s nostalgia. The bananas in the original game had stickers on them, but the newer games didn’t. There are a lot of people who love the old SMB games and are happy when anything is done to make the new ones like the old ones.

    I don’t get being so excited about it, but these games weren’t a core part of my childhood. I played the party games in SMB 1 once and those were fun, but I don’t think I ever actually played the main game.



  • Yeah, I’ve been wondering how the fuck they pulled this off. If it turns out that the only pagers that exploded belonged to Hezbollah members, then that would signal to me that this was done entirely digitally.

    I’ve heard that batteries (can’t remember if it was laptop or phone batteries) contain the energy of a small grenade, but getting it to release that energy all at once without physical access is absolutely fucking wild and has serious fucking implications for device security.

    EDIT: To avoid spreading misinformation, I’m providing this edit to say that the batteries absolutely were not the cause of the explosion. This was a supply-chain attack. Explosives were inserted into the pagers. The batteries in these pagers cannot be made to explode like this. I was overly excited when I made this comment.


  • 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.
