  • I tend to agree, but I would set the age lower. A person can graduate high school at 18, get a 4-year degree, and still be 3 years away from “adulthood” by your definition. There are plenty of professionals in the first 3 years of their career who are contributing members of society. Shouldn’t they be able to drive to work, sign a rental contract, etc? I’ve been in my career for over 20 years, and I have always worked with young people who may be lacking experience but are still productive employees. I think you’d be cutting out a significant portion of the workforce by excluding those in early adulthood.


  • $3.4M is too low of an estimate. If you assume someone works from age 18 to 65, that’s 47 years of employment at an average of $72,300-ish per year. Now assume time for college, plus people make less early on in their careers. You’re looking at a $100k income.

    $100k is probably enough to support a mortgage, two kids, insurance, essentials, bills, and retirement savings in some LCOL areas, but not in many places. In many parts of the US, that might cover a modest house and monthly bills, but there won’t be much left over; forget retirement.

    My old brain still looks at a 6-figure income as “you’re rich.” In 2024, you’re not even close.




  • If you can afford one, I would strongly recommend going with a dual-conversion UPS. A line-interactive UPS like the one you posted essentially acts as a pass-through for your mains power until it detects a power loss or a brown-out. This works most of the time, but there’s a short delay during the switch from line to batteries (just guessing, but most likely on the order of milliseconds). This might not sound like much, but you’re counting on the capacitors in your server’s power supply to hold enough charge until the UPS kicks in.

    The other thing to consider is that a dual-conversion UPS also supplies “clean” power to your equipment. It essentially acts as a DC power supply connected to an inverter, so regardless of how bad your input power is, you’re always going to get the correct voltage and frequency out. I connected my old line-interactive UPS to a cheap generator at one point; the voltage and frequency regulation was so bad on the generator that my UPS continually switched on/off of battery (several times per second), and the equipment attached to it immediately shut down.

    I can connect my dual-conversion UPS to the same generator, and it keeps humming along as if it was connected to mains voltage. According to the datasheet, anything from 60VAC to 150VAC, it’s still going to output clean 120V/60hz power.

    They’re much more expensive. Mine is 1000VA, and if I remember correctly, I paid something like 600 or 700 USD for the UPS. An add-on rackmount battery pack was another $300 or so. It was well worth the cost, though.





  • Depending on how accurate you need your energy usage data to be for individual devices, you might be able to get away with just using a whole-house energy monitor. I’m using one of these:

    https://www.amazon.com/gp/product/B08LV8DDFP

    I already have a large number of Zigbee plugs, so by looking at the power usage from my energy meter before and after one switches, I can get a general estimate of how much power a device is using. Of course, the rest of your home is going to to skew the results, but you can mitigate this a bit with some of HA’s statistics functions. It’s been a while since I tried this, but I did test it with a 3.5kW heater a while ago. I took a median from a certain number of samples before and after the heater switched on (I think 10 seconds worth of samples), and the result was generally accurate to within about 100w.





  • I don’t consider myself a Republican or a Democrat, although unless things change drastically in American politics, I can’t see myself ever voting Republican by the time I’m dead and gone. With that said, I mentioned to someone yesterday that if I didn’t have the experience of living through Trump’s time in office, this debate would make me seriously consider voting for him.

    I really don’t believe that this debate is going to sway many undecided voters toward Biden. If you compare their performance at face value, Trump was unusually well-spoken, and Biden seemed like he belonged in a nursing home. Half of what Trump said was complete bullshit, but how many undecided voters are actually reading articles that show how full of it he really is?

    What you have is a person who stated lies as fact and did a decent job of being convincing and a person who was generally truthful but seemed like he “wasn’t all there.” Undecided voters who “don’t follow politics” are going to see this and say “You know, I think I understand why people support Trump.” That’s a very scary prospect.

    I don’t dislike Biden, but my personal opinion is that the best thing he could do for the country is step aside and let a different Democrat take the nomination. Geriatrics like Trump and Biden need to retire, do whatever they feel like in their golden years, and let someone else take the reins. A competent politician in his 50s or 60s would absolutely destroy Trump, and that’s exactly what we need right now.



  • The specs say it replaces a traditional 500w-1500w light source with a 200w LED fixture. I’m honestly surprised at how low that is overall. I would expect that a lighthouse would be using at least 10kw of power or more, especially in areas prone to fog. I can only assume that there are lenses to focus it down to a tight beam.

    For comparison, I recently installed LED lights in a moderately-sized industrial area. Total power consumption is a little over 2kw, or 10 lighthouses.


  • Speaking from experience, be careful you don’t become over-zealous in your anti-scraping efforts.

    I often buy parts and equipment from a particular online supplier. I also use custom inventory software to catalog my parts. In the past, I could use cURL to pull from their website, and my software would parse the website and save part specifications to my local database.

    They have since enacted intense anti-scraping measures, to the point that cURL no longer works. I’ve had to resort to having the software launch Firefox to load the web page, then the software extracts the HTML from Firefox.

    I doubt that their goal was to block customers from accessing data for items they purchased, but that’s exactly what they did in my case. I’ve bought thousands of dollars of product from them in the past, but this was enough of a pain in the ass to make me consider switching to a supplier with a decent API or at least a less restrictive website.

    Simple rate limiting may have been a better choice.



  • Microsoft knows that the addition of adds to Windows, Recall, data mining, etc are not suicide. As far as tech news goes, Lemmy really exists in an echo chamber. The vast majority of us at least have some interest in technology. For the majority of the population, though, this isn’t true. The typical person sees a computer as a tool to be used for other things. They’re not reading articles about the latest release of Windows, new CPU technology, the latest GPU, etc. They’re using their computer, and when it’s time for an upgrade, they buy whatever suits their needs.

    If I was to ask any of my family, or most of my coworkers, about any of the latest “controversies” surrounding Microsoft, they would have no idea what I was talking about. Microsoft obviously thinks that the added profits gained by monetizing their customers will offset the loss of 1% of their users that switch to Linux. They’re probably right, too.

    I like Windows, personally (well, Windows 10 at least). My unofficial rule has always been if it needs a GUI, then it runs Windows, otherwise, it runs Linux as a headless machine. Once Windows 10 is no longer a viable option, my unofficial rule will be “it runs Linux.” Most people will not make this switch.







  • Finishing a project for outdoor use is really a bit of a balancing act between looking like wood and looking like plastic. Something like a hard-wax oil (or even just boiled linseed oil) maintains the look of the wood but provides little protection against the elements. On the opposite side, paint will provide fairly good protection… but lets be honest, paint is really only appropriate for plywood.

    I finished two pieces of outdoor furniture a few months ago; both were made from Alder. For the finish, I ended up with 2 (maybe 3) coats of matte spar urethane. It gives good protection (it’s originally for marine use), but it doesn’t significantly alter the look of the wood. You can certainly tell it’s a film finish, but (at least to my eye), it doesn’t have the “plastic” look you get from a glossy poly or an epoxy finish. There’s a bit of a shine to it, but it’s fairly minimal, even in direct sunlight. So far, both pieces are holding up well, and they’ve been subjected to a range of temperatures and heavy rain. I hate film finishes, but the next time I build something for outdoor use, I’ll probably use it again.

    It’s also worth considering what kind of wood you’re using and how you want the piece to age. Something like cedar is naturally rot-resistant, but it will develop a grey “patina” over time. I have read that Sapelle is very good for outdoor furniture with no finish, but I haven’t used it myself. Personally, I’m not a huge fan of the “weathered” look, but a lot of people really like it. My girlfriend wanted a bird house a few years ago, and I made it from a simple white cedar with no finish whatsoever. It has definitely turned grey, but it’s just as structurally solid as when I first built it.
