  • 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.








  • 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.




  • In the US at least, most equipment (unless you get into high-and datacenter stuff) runs on 120V. We also use 240V power, but a 240V connection is actually two 120V phases 180-degrees out of sync. The main feed coming into your home is 240V, so your breaker panel splits the circuits evenly between the two phases. Running dual-phase power to a server rack is as simple as just running two 120V circuits from the panel.

    My rack only receives a single 120V circuit, but it’s backed up by a dual-conversion UPS and a generator on a transfer switch. That was enough for me. For redundancy, though, dual phases, each with its own UPS, and dual-PSU servers are hard ro beat.



  • 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.



  • What is human connection, though? It’s your brain releasing dopamine because you spent time with another person. It matters to you because it makes you feel good. Other things can make you feel good, too. The difference is that hobbies and activities won’t let you down. They won’t stop being your hobby because they’d rather spend time with someone else. People are unreliable and ultimately selfish at heart.

    Say you make a friend. 60 years from now, you and your friend are both dead, and what’s left behind? Nothing. I’m not old, but I’m certainly not young either. It took me a while to realize that other people just don’t matter. In the end, nothing matters at all; everything you and I do is ultimately going to fade into irrelevance when we’re dead. Might as well make the most of the time we have alive, then; do something that makes you happy. Don’t rely on another selfish human being for your happiness.


  • You don’t. People need fulfillment, not human interaction. Find something you are passionate about and pour your time and effort into it. Buy a classic car and restore it. Learn how to make your own furniture. Start learning photography. Write a book. Develop a program or app. Start a fitness routine. Brew your own beer. Learn a foreign language. The list is endless.

    What matters is doing something that brings you satisfaction. A hobby that involves creating something or improving yourself is so much better than wasting time with other people. Spend a day hanging out with friends, and what do you have at the end of the day? Nothing. Spend a day planting a garden, and what do you have at the end of the day? You have a nice garden.
