RAID is more likely to fail than a single disk. You have the chance of single-disk failure, multiplied by the number of disks, plus the chance of controller failure.

RAID 1 and RAID 5 protect against that by sharing data across multiple disks, so you can re-create a failed drive, but failure of the controller may be unrecoverable, depending on availability of new, exact-same controller. With failure of 1 disk in RAID 1, you should be able to use the array ‘degraded,’ as long as your controller still works. Depending on how the controller works, that disk may or may not be recognizable to another system without the controller.

RAID 1 disks are not just 2 copies of normal disks. Example: I use software RAID 1, and if I take one of the drives to another system, that system recognizes it as a RAID disk and creates a single-disk, degraded RAID array with it. I can mount the array, but if I try to mount the single disk directly, I get filesystem errors.

Treasuries are nice because they’re convenient and low buy-in, but their yields are crap, sometimes a little above inflation, sometimes below. TIPS are a decent way to hedge the inflation risk, but (IMO) it’s still really for people who are more worried about losing their savings than living off it. (i.e.: if you have, say, $1e8, you can live pretty comfortably off $1e6, even $1e5 in a lean year, so your rate of return doesn’t really matter)

For me, personally, the limited bond exposure I have is all corporate and mostly junk, bought through my broker in the secondary market, with maturity 10-20 years out. Until fairly recently, junk bonds were the only way to get yields above 4%, and that’s kind of my mental benchmark for gaining relative to inflation. One downside of corporate bonds is they generally have a $10k minimum.

That drop was when the Fed was raising interest rates to stall inflation. Interest rates up, bond values down. But the drop in VTINX was only 20% over all of 2022, where OP is showing 50% in maybe the first quarter.

Incidentally, the sensitivity to interest rates is why I don’t like bond funds. If you buy actual bonds, you get the face value back at maturity, where bond fund are forced to mark them all to current market prices to calculate NAV. IMO, this negates the main “safe” factor in holding bonds.

Yeah, OP isn’t telling us everything. He’s got a 50% decline in what looks like January 2022, where FSKAX and VTI were off by ~10%. Half that drop looks like it happened on one day. In fact, now that I look at it, it’s kind of reminiscent of a BTC chart.

No. If you’ve been saving for 30 years, then you’ll have 30 years of accumulated 10±20% annual gains, which should be something like 16x your start, but could be 100x if you’re lucky or 1x if you’re not. Regardless, an historic crash on retirement day may take that down to 12x your start, which is still pretty good, and will be fixed by the following couple years.

I get political spam addressed to three different people who used to have my number. Real estate spam for one of them. Temp job offers for another. It’s annoying af going on four years.

Yeah, if this is what it takes to get new design nuclear facilities in the US, then I’m counting it a win, but I won’t count it either way until the watts come out. Who knows: if they run ok, an actual power company might even try one.

And X-windows. There’s a few server tasks that I just find easier with gui, and they feel kind of laggy over 1G. Not to mention an old Windows program running in WINE over Xwin. All kind of things you can do, internally, to eat up bandwidth.

If you’re technically inclined, Big Clive has a tutorial for ‘fixing’ most bulbs not to overdrive the LEDs by removing or changing a single resistor. https://www.youtube.com/watch?v=5HTa2jVi_rc

Have an updoot, Offspring-fan.

University is ok if you’re starting at zero and don’t even know what’s out there. It’s for exposing students to a a breadth of topics and some rationale of why things are as they are, but not necessarily for plugging them into a production environment.

Nothing beats having your own real world project, either for motivation or exposure to cutting edge methods. Universities have tried to replicate that with things like ‘problem based learning,’ and they probably hope that students will be inspired by one or two of the classes to start their own out-of-class project, but school and work are fundamentally different ways of learning with fundamentally different goals.

Without an adblocker, I used to mute the system and put youtube in a background window. Do something else long enough for the video and all its ads to play, then go watch it. They wouldn’t play the ads on a second play through, and it would interrupt the cycle of constantly playing a new video.

I have something similar, but wifi. Never even tried to connect to it, because you just use the buttons to set temp & time.

I can imagine, though, that an app might have buttons for ‘eggs’, ‘yogurt’, ‘steak’, etc. Or maybe let you program temperature-time sequences. Or let you check how much time is left from the next room. Conveniences. Definitely no need for them to phone home, though, except maybe for an ad-driven ‘recipe of the week’ type thing.

Colon is part of your large intestine.

You’d need some way to cache that video, though, because it’d take 24 hours to write 8TB at SD card speeds of 80 MB/s.

2. What electricity costs in my area. $0.32/KWh at the wrong time of day.

I assume you have this on a UPS. What about using a smart plug to switch to UPS during the expensive part of the day, then back to mains to charge when it’s cheaper? I imagine that needs a bigger UPS than one would ordinarily spec, and that cost would probably outweigh the electric bill, but never know.

The politicians made sure to exempt themselves from all the consumer protection, anti-fraud laws. They live in bubbles where their own political agendas are too important for limitations.

But I suspect, because my brand new phone number gets a lot of political spam, that 1) a lot of people can’t live with it and change their numbers to escape or 2) a lot of it is recycled burner-phones, previously used to launder donations to fit legal donation limits. But it’s given me a personal rule to never make a donation from my real phone or allow my real phone to become associated with any political process.

I came to MySQL and Apache because they were the backend for other services I wanted to start,. Later, when I wanted to build my own, I already had Apache running, so why would I add nginx? I did let other services add sqlite, but have (in most cases) figured out how to switch those to MySQL.

All of that has been running for 20 years. I’m sure it would be good for my dementia-risk to learn how to start ngnix and migrate all those services, but it’s far more attractive not to mess with what works.

The CO2 sensor calibration thing is inherent in the technology. They drift, a lot, and without occasional reference to a known standard, there’s no way to know whether “1000” is really 1000, or 500, or 2000, but exactly how that gets implemented seems to vary a lot. I have an SCD30 board from Adafruit, which internally records CO2 minima and, over the course of week or so, adjusts its calibration so that minimum is 420. That means no special calibration procedure, but it does have to be somewhere that it gets periodic fresh air exposure.

There’s a newer, photoacoustic sensor technology that doesn’t seem to require continuous recalibration, but (at least this one: https://www.sparkfun.com/products/22956 ) require an extensive initial calibration.

My CO2 sensor has dramatically changed my routines. My space isn’t small - maybe 1200 square feet/100 sq m - but it must be pretty well sealed, because I can easily see my own breathing add to CO2. Nevermind cooking on the gas stove. Treadmill time adds 500+ ppm.

Now, I open windows every chance I get (which isn’t super often, because the dewpoint is 70 oF/20 oC in Atlanta), and I’ve shifted a lot of my cooking to an electric tea kettle, hot plate, and toaster oven.
