Anyone replying “stretching” is basing their response on grade school gym class, not science.

Studies have not shown that stretching has a positive impact on injury prevention, and this has been widely known in the literature for over 20 years. Stretching can improve performance in some sports like gymnastics where increased flexibility is needed, but that is unrelated to injury.

Stretching has a negative effect on performance in other cases because it actually decreases muscle force generation.

Think about it, would you think that loosening all the belts on a machine would automatically make it less likely to break down?

So what does prevent injury?

• Good warm-ups. Walk before you jog before you run. Lift an unloaded barbell before a loaded one, etc.
• Strength. A joint surrounded by muscle is a stable joint. That means doing exercises that strengthen all the muscles, including minor ones. It’s part of why most people who know what they are talking about will try to get you to do compound lifts with free weights over single joint exercises on machines.
• periodization/progressive overload. Basically slowly building intensity and then backing off to recuperate.

Yeah, you are spot on.

Solar irradiance above the atmosphere (i.e., in orbit) is 1360 W/m^2. At ground level, it’s 1120, so a loss of ~18% due to the atmosphere.

If transmission losses plus the massive costs of launch, keeping the panels cool (no conduction/convection in space), and maintenance add up to greater than 18%, it’s more efficient on the ground.

BinaryEye (for scanning qr codes)

Do you have a recommendation for generating QR codes? I basically want to be able to make qr codes that link to notes so I can see what’s in boxes without having to pull them out of hard to reach spots. I see a couple options on fdroid (QRshare and ShareAsQR), but I’m sure there are desktop applications, too.

Yeah, definitely. I would argue that “nutritious” should mean “can I live off of this?”. From that context, you need high calorie, balanced macros, and no glaringly missing micronutrients.

I wonder if anyone’s made the soup version of completefoods.co (which is like a DIY soylent-making site).

Depends on your definition of nutrition. 100 g of kale only has 28 calories, so if your definition of nutrition is “can I live off of this?” the answer is no. If it’s more of a “is this good for me?”, the answer would be yes.

You just need to temper the egg. Scramble in a separate bowl, and slowly drizzle in hot broth until you’ve added like 5x the volume of the egg yolks while whisking. After that, you can just pour into the pot. It’s how you do it for ice cream and other custards, too.

I mean, they should be the ones funding this stuff all the time (it should just be involuntary on their part)

Yeah, I’m tired of the “x law says he can’t legally do y action, so we don’t need to worry about it” discourse that the media keeps amplifying. The executive branch is in charge of enforcement, and he’s made it clear to congress that he has sole control of the branch, and he’s wielded that power to break so many laws already.

It’s not like there’s some constitutional overlord that steps down from heaven to put him in jail if he tries to run again.

I’m in the same boat. Well, not pool water, but it does have chlorine i want to remove, so i use a brita, too. I just know too many people with hard water who try to use a filter to remove it, even though that’s not really the way that filters work.

That won’t really reduce hardness. The cheap Brita filters will replace some minerals with salt, but mostly they are there for filtering out pathogens and heavy metals ions/other contaminants with the active carbon.

Clean≠soft. You can have very hard water that’s clean, or very soft water with bacteria, heavy metals, and pesticides in it.

Also, unless you live in a microstate, water quality is going to be really regional. Assuming you are in the UK, a place like Burton-on-trent has notoriously hard water (which lead to the creation of the IPA).

Great comment, and I’ll add that police, by the nature of their jobs, have to deal with a lot of things that people would (and should) find traumatic: grisly accidents, homicides, overdoses, etc. Obviously, EMTs have to deal with that kind of thing, too, but at least they usually have a partner they can talk to. Despite TV always doing the buddy cop thing, cops usually work alone.

Everyone knows it’s a problem, but the main solution has been absolutely shoveling money at grifters like Dave Grossman to give seminars and write books on “killology” (wish I was making that up). The guy’s highest level of schooling is a masters in education in counseling, but he disguises that to try to make you think he’s a proper psychologist or psychiatrist. Once you know his hypotheses, which are pulled out of thin air and unsupported by data, you see them absolutely everywhere steeped into the culture of cops and military in the US.

Newegg really went full Amazon in a bad way. Microcenter is also still good as far as I can tell.

I never understood audible. You pay $15 a month to be able to listen to 1 book per month?

Shout out to librivox, if you haven’t heard of it. It’s audiobooks recorded by volunteers reading public domain books. Obviously hit or miss on the quality of the reader, but it’s free, so you can’t complain.

Also, obviously, the humble local library and libby. (P.s., if you can get a few cards to different library systems, it’s really easy to get books).

Ah, I wonder if it was new enough to not be dead simple, but not new enough to not have any documentation or spare parts?

I didn’t even know what a zipper foot is, but it turns out I have one, lol. That shows what I know.

What was your hand-me-down? I’m working with a 1950s machine, and it seems to work great for me, but i have to admit I haven’t used a machine built in the past 20 years, so idk what I’m missing.

Most modern sewing machines have capability to do so much more than you probably really need.

Personally, all I really need is a machine that can do straight stitches with adjustable stitch length and reversing. I have a 1950s machine that does that, and it was free to me, and there’s attachments for zigzagging if I want.

If you are just patching and altering clothes, that’s probably all you need, too.

I’m the other way around. Anything I buy i want to run off 18650 (or similar) cells, and i don’t like anything that requires disposable batteries.

This is something I keep getting close to buying, but it seems like all the reputable brands i know are very expensive.

Then there’s “6-letter, All-Caps”-brands selling for like 1/6th the price and they are app controlled which is bad to me, and I’m suspicious of those brands, anyway.
