• The cost of digital advertising cannot be justified by its effectiveness (or rather lack there of). We’ve collectively spent hundreds of billions of dollars creating the infrastructure for invasive hyper targeted ads that do not get better results than simple billboards and terrestrial TV ads even now. We’ve created a global economy of marketing, media, advertising and sales solely reliant on technofeudalist overlords who’ve provided very little actual improvement of anything.

    The world is littered with fake empty buildings used to obscure phone line junctions and internet provider stuff.

    Almost every neighbourhood has one. But they look like normal houses, so you can never tell unless you know where to look for.

  • Most of hacking is done by mass effort with maybe a couple percent of people that aren’t doing basic things to protect themselves being affected. That couple of percent is enough to keep the hackers flush. (So please, follow basic cybersecurity steps, people.)

    The plain truth of the matter, though, is that if a hacker or group of hackers is targeting someone individually for reasons, that person is in real trouble.

    This has been a PSA for everyone chasing fame and clout.

    • I miss the days of Anonymous (there was a sub group of the actual hackers whose name I can’t recall and a bunch of wannabes I guess providing them a crowd to lose themselves in) doing justice hacks. Not that they were always on the right side of things, but now everything is state actors trying to bring us all closer to Armageddon.

    • Tips for being secure online:

      1. Use your browser’s password manager to generate random passwords.
      2. In the rare case you need to manually enter your password into a site or app be very suspicious and very careful.
      3. Never give personal information to someone who calls or emails you. If necessary look up the contact info of who called you yourself and call them back before divulging and details. Keep in mind that Caller ID and the From address of emails can be faked.
      4. Update software regularly. Security problems are regularly fixed.

      That’s really all you need. You don’t even need 2FA, it is nice extra security but if you use random passwords and don’t enter your passwords into phishing sites it is largely unnecessary.

          The reason I say browser password manager is two main reasons:

          1. It is absolutely critical that it checks the domain to prevent phishing.
          2. People already have a browser and are often logged into some sort of sync. It is a small step to use it.

          So yes, if you want to use a different password manager go right ahead, as long as it checks the domain before filling the password.

          • What do you mean a password manager that checks the domain? Isn’t the auto fill based on the domain? I can’t imagine how a password manager could fill a password without checking the domain, it wouldn’t know which password to fill after all. Do any actually exist?

            • There are some password managers where you need to either manually look up passwords and copy+paste or autotype them or select the correct password from a dropdown. Some of these will come with an optional browser extension which mitigates this but some don’t really tract domain metadata in a concrete way to do this linking.

              Some examples would be Pass which doesn’t have any standard metadata for domain/URL info (although some informal schemes are used by various tools including browser-integration extensions) and KeePass which has the metadata but doesn’t come with a browser extension by default.

    • I’m on a game, Whiteout Survival, you’ve probably never heard of it. I haven’t spent a penny, but I was curious about how much one obscure “upgrade” cost. Mind you, there are hundreds of purchases in the game.

      It was $100 US, and it said 29,000 had been sold… in the last WEEK!

      2.9 million dollars a week for NOTHING. And that’s just that one obscure item, far from their biggest seller.

      And that’s just in one game you’ve never heard of.

      • You’re a non-monetizer, just like 95% of the players. The game will make you some form of offer in order to convert you into a paying minnow, dolphin or whale. Whales are rare, less than a percent of the players, but they generate a significant amount of the revenue.

        Companies compare their conversion rate with each other and have specific goals to meet. 5% for example is good. If your company has say 3%, you’ll want to focus on improving that. Each product will have a specific goal here, and otherwise is shut down because there’s a customer acquisition cost. Games easily cost more to market than to develop.

        A lot of effort is spent on the first offer. This is where you’ll see a screen that makes an amazing offer you’ll seriously consider. It’ll have something that is high value but incredibly cheap and so temporary. This isn’t to earn money, it’s simply to convert you. Because after you’ve spent your first dollar you’re likely to keep spending.

        • A buddy of mine spent several thousand on Marvel Heroes. He wouldn’t go out to lunch with us, and finally I asked him what was going on. He eventually told me, we had a “dude…we are adults and can’t be doing that shit. Imagine the hookers and drugs you could have bought!”

          He quit, but still tells me he thinks about it and is immediately filled with regret.

          • One time I nearly cut a job due to being asked to make something gambling related, but when I worked on an addictive mobile game I simply didn’t realize what I was doing. Honestly, I couldn’t have known unless I had asked about their monetization strategy before they brought new people on to implement it. And at that point the game was as good as done. I remember walking through Barcelona and seeing all these kids on their phones in the park and not playing or having fun, it felt surreal. I bawled my eyes out and didn’t return to the job. You know I genuinely just wanted to give people some fun in this world.

            The issue with mobile games is that nobody is prepared to pay even 5 euros for a game. So for mobile game developers it is business as usual to do it this way.

    • I was suckered into the shark cards on GTA Online, I worked terrible hours and it was my escape.

      I bought shark cards for thousands of SEK ocer a year or so, not much in compared to normal whales, but I did feel the addiction drawing me in harder.

      Then one day I had just had enough, and uninstalled the game, else I knew I would continue.

      I am glad though, the money I spent was not wasted, it taught me a valuable lesson about what to look out for, and how to recognize sinkholes like this.

    • They have ARPU targets (Average Revenue Per User) and UAC targets (User Acquisition Costs). Whales contribute significantly to the game’s bottom line. Non-paying customers are vital, because player population is a game quality, and Whales need a population to notice how awesome they are.

      But game companies don’t tend to separate Whales from other players (at least not the ones I’ve worked for), they tend to care about ARPU, which is more stable, and a much easier target to shoot for. And they want to keep UAC down, which lowers the required ARPU for a successful game.

      I fear too many universities are businesses designed to fund seminars; and students graduating are whether an afterthought or an actual negative for them.

      It was related to me that, because they want to keep their customers, one can solve any problem at uni - grades, minor victimless crimes, etc - simply by offering to take more courses. The only problem money can’t solve is the one where the student has no more money, and it’s over quickly after that (saw that one happen).

      • It is far worse than that.

        Universities have a lot of metrics that they are judged against that don’t lead to a quality education. Research doesn’t lead to good undergraduate students. A good pass rate just means the curriculum is soft enough to keep don’t students from failing.

        So you have university presidents who are incentivized to increase prestige and they aren’t going to focus on the quality of education because that doesn’t lead to better metrics. If presidents try to defend their universities’ way of teaching, they get replaced by those who follow the system.

    Building HVAC engineering (equipment sizing, ducting design, etc.) has been largely handwavy bullshit for a very long time and only recently has moved towards any sort of precision. Not uncommon to find boiler plants that are 3-4 times the maximum heating load in the winter, or fans running at 100% 24/7 when code only requires half of that.

    Costs just get passed on to tenants so there was never much motivation to do better, the only reason building owners are moving now is because of government regulation and incentive programs.

    • I used to work in HVAC. I remember we had a small cold room that was struggling to maintain temperature, as in, design was supposed to be 0°F but it couldn’t get below 36°F. There was a large hole in the box that was undoubtedly the cause of the problem, so I asked the installer how they accounted for that. “Oh, I doubled the infiltration value.” When I tried calculating the actual losses it was way, way higher than the infiltration value. Like, the room needed someting like 3-4 times its total refrigeration capacity to reach target with a giant fucking hole in the box.

      No idea who thought putting a giant hole in the box was a good idea.

    • I work in building science. It’s obscene how little actual design and quality control goes into residential homes.

      The typical design is just one step above being illegal, and people are often scared off of doing anything more than that by the threat of increased cost. However, they don’t realize that they pay for it either way; either on their mortgage, or on utilities. Only one of those you can actually own in the end.

  • ~Things people don’t want to know~

    Putting a layer of tissue between your butt and the toilet seat doesnt provide enough of a barrier against microorganisms over the time it takes to shit or piss to prevent transmission.

    Keeping the air dry reduces both the length of time microorganisms can live outside your body and the length of time that vapor particles can harbor them.

    The n95 (and other) rating(s) are over time in free, circulating, open air. Derate safe exposure time sharply for use inside or in spaces with stagnant or unmoving air.

  • A whole bunch of welds in nuclear reactors are visually inspected using cameras duct taped onto the end of incredibly long poles which also get duct taped together. This would be the inside of BWR plants near the fuel and jet pumps. There is also an “art” to moving the cameras and poles around to get the shots you need. And if you get stuck the talented people know how to get you unstuck. There are also cameras just duct taped to ropes that the camera handler “swims” to certain spots.

    Don’t get me wrong, we have cool ultrasonic inspecting robots as well, but I was absolutely blown away by what visual inspection looked like in practice.

    PS: The high dose fields make the camera look like it is being blasted with colorful confetti because of the high energy particles bombarding the camera module.

    75% of American drinking water needs treatment to reduce particulate and parasites, and the treatment additive used to render the water safe is produced at a single chemical plant located in an area of severe flood risk – which means that a flood could take it offline for a day or two, or damage it for weeks.

    (Efforts to build a second site recently fell through due to ever-changing regulations. Of course they’re stockpiling it in some mountain bunker, I’m sure)

    The next Katrina could give us a brain-worms infestation via tap-water.

  • I want to comment here so bad but given that I am one of two people that know and one of maybe a dozen that suspect, it would definitely violate multiple NDAs.

      There are more than 2 people that know that Texas’s power grid is a teetering disaster waiting for the right event to crumble and break in unfixable fashion

      (Or water, water’s probably even more sketchy. Look up the incident in the UK where they accidentally put a shitload of treatment chemicals in the main water supply and a whole bunch of people got poisoned. Harder to do off grid solutions for though.)

      • Ha! I used to live in Austin and I don’t fly, so Buc-ee’s and Cracker Barrel hold a special place in my heart. Unfortunately what I am talking about is a US thing, not just a Texas thing.

    With the exception of at large buildings in dense city centers, just about everywhere else, utilities enter a building at just some point on the back, out in the open. This includes utilities that feed alarms and security cameras.

    While some places will have systems in place for situations where these outside connections have been severed, like independently operated cameras on an intranet, cellular data backup for alarms, electrical generators, etc., most places don’t, so successfully circumventing their security is just a matter of cutting all the cables on the back of their building at the same time, and then being gone before they notice

    • I’m not an expert on modern alarm systems but it seems that it is very common and fairly inexpensive to have cellular data backup. Not every system has it, but many do. In that case cutting the main connection will likely result in someone appearing on site fairly quickly.

      Many cameras also have some form of local buffering. So even if you are gone before someone does show up you still may find yourself recorded.

      But at the end of the day just put a bag over your head and you can be gone by the time anyone shows up without leaving a meaningful trace. Other than the very top-end system security systems just keep the honest people honest.
