  • I mean it depends on the intensity of the surge, but basically you’d be making it so your PSU is unable to protect the devices from surges. The more sensitive the electronics, the more critical the ground is and CPUs are pretty darned sensitive among other things. And depending on the type of components in the PSU, “surges” also include things like inrush current. Basically, when you turn on a transformer or certain other devices, there is a surge of sometimes as much as 10 times the rated current to create the initial magnetic flux. Depending on the components, this excess energy may end up getting shunted to the ground to avoid pushing it through your electronics. So if it can’t do that, you likely will blow fuses a lot when switching the power on (hopefully there are fuses), or if you’re touching the case which is supposed to be grounded, you may end up getting that jolt.

    Anyway, without grounded outlets, and especially if your electronics are cheaply made because many expect there to be grounding and don’t build in extra components to deal with not having a ground, you are likely to significantly reduce the life of your electronics, your life, or start a fire without even considering major surges. If you have a high-end PSU, you may never have a problem until that surge happens. How stable is your power? Because even a normally small surge combined with a cheap PSU, and no ground, is pretty likely to end up in damage to electronics at the best case.




  • I’ve never seen any math that disproved that. Now if you’re looking at actual federal income tax paid, maybe, but social security tax is based on income, it doesn’t get reduced by often fraudulent deductions and credits. So a lot more income is taxable under social security tax than federal income tax which is laden with loopholes and complexities. So when Jeff Bezos in 2007 paid $0 in income tax, he likely would have paid tens or hundreds of millions in Social Security tax if there wasn’t a cap, because he did have income. Of course, we aren’t legally able to get the actual numbers because of privacy laws, but there have been some leaks recently if you want to see some of the numbers.


  • Because computers have come even close to needing more than 16 exabytes of memory for anything. And how many applications need to do basic mathematical operations on numbers greater than 2^64. Most applications haven’t even exceeded the need for 32 bit operations, so really the push to 64bit was primarily to appease more than 4GB of memory without slow workarounds.



  • Automate as much as possible. I rsync to both an online and home NAS for all of my hosted stuff, both at home and in the cloud. Updates for the OS and low level libraries are automated. The other updates are generally manual, that allows me to set aside time for fixing problems that updates might cause while still getting most of the critical security updates. And my update schedules are generally during the day, so that if something doesn’t restart properly, I can fix it.

    Also, whenever possible I assume a fair amount of time for updates, far beyond what it should actually take. That way I won’t be rushed to fix the problem and end up having to revert to a backup and find time later to redo it. Then most of the time I have extra time for analyzing stats to see if I can improve performance or save money with optimizations.

    I’ve never had a remote provider just suddenly vanish though I use fairly well known hosts. And as for local hardware, I just have to do without until I can buy a replacement. Or if it’s going to be some time, I do have old hardware that I could set up as a makeshift, temporary replacement like old desktop computers and some hardware that I use for experimenting like my Le Potato that isn’t powerful enough for much, but ok for the short term.

    And finally I’ve been moving to more container-based setups that are easier to get up and running again. I’ve been experimenting with Nomad, Docker Swarm, K3s, etc., along with Traefik and some other reverse proxies so o can keep the workers air-gapped for security.


  • Best practice varies based on the specific use case, but generally you don’t want to modify sound any more than you have to. The more you modify, the more it has the potential to distort the sound depending on the quality of the particular amplifier and other components. It can get complicated, especially with hardware/analog EQs because of physical quality of the wiring, connections, and components. So, in general, it’s best to leave most things at 0db and change only the things you want to change. However, there are exceptions. Like if you want to change all but one of the frequencies by -4db, you’re better off changing the main amp by -4db and increasing just the one you didn’t want changing by 4db this the EQ is only modifying a small amount of frequency and the rest is passthrough. And generally the main amp is going to have less distortion than the EQ.

    That being said, this is talking about cases where your tolerance for distortion is extremely low or you have a really shitty EQ, in which case it’s probably better to just throw it out and forget the whole thing 🤣. Because most people aren’t going to notice the difference of using the EQ for amplification or the main, even if they aren’t the best quality.

    So, if you really are as picky about stuff that doesn’t matter much, but just want things to be as perfect as possible, like me, balance towards 0 as much as possible using both the EQ and the main. Otherwise, do whatever, probably no one will know the difference.

    Also, I know the math isn’t exactly right for the -4 and +4, but there are other things you need to know to get it perfect anyway for one inline -4 to equal another inline +4. But it’s close enough…




  • But it’s not just Detroit that matters in this case since the presidential election hinges on total for the state, not individual voting districts. So sure, he’s not going to win the district but that doesn’t affect the race. So since Detroit is the largest city, it’s still the place to convert more people at once. And he doesn’t need to convert them to vote for him. He just needs to convince them not to cast a desperation vote against him.


  • Sounds like she had some kind of violent allergic reaction to the drink or had taken some sedatives or other medications that might have caused a bad reaction. Or maybe just before the flight she drank a whole bunch and it just hadn’t hit her yet. I can’t see a single drink doing that, even for someone with a phobia or trauma. Hope that if it was something she had no control over, they’ll at least take that into account. But if it was a mix of sedatives or she really was that drunk, then yeah, totally throw the book at her.




  • Problem is that insurance companies follow requirements, not recommendations. So once the requirements and funding are gone the coverage is removed. Recommendations then take time to be considered for implementation based on if they are going to save the company money. But that needs to be proven to executives with data. And since many states no longer track COVID cases due to political biases and there’s no longer funding to pay for the expensive vaccines or the research to provide that data, and with most large corporation executives being right leaning and the current political right being against vaccines, many are choosing not to cover it, except for people over 65 which is the at risk group. Just like it was always recommended that everyone get the HPV vaccine, but it wasn’t until recently that it was covered for adults. It’s all about cost vs risk since our healthcare system uses an insurance model instead of a public service model.

    So, if your insurance will cover it, definitely get it. If not, it’s pretty expensive and the government is no longer picking up the bill. I just had COVID from traveling and that was my first time. Likely mostly because I didn’t have the booster this time.
