ml would like a word.

That needs to be in the form of a question, right?

There is a caveat, but yes: By definition, 3D printed parts should not be considered food safe.

Single-use cookie cutters are generally OK if you don't use them multiple times a day every day.

There are probably minor chemical risks but it wouldn't be in high enough quantities to kill you. There isn't really anything inherently food unsafe with PLA, ABS or PETG.

Bacteria is a much bigger risk during reuse because you can't fully clean the prints between the layer lines and other surface defects. The plastic generally won't survive a proper sanitization process either.

What your own risk tolerance is for plastic additives is up to you. If you do print a cookie cutter, toss it after you are done.

HF tools are not designed for the long term, generally. If you need a tool to work at least once, for one job that you are never going to do again, HF is "good enough".

The rule of thumb is to never buy a tool there that could result in a gruesome death if it fails to protect your life, like jack stands. (Invest in quality safety equipment first if you get something like an angle grinder.)

It's just a surface to air missile. 100 is quite a few, but considering how drones are used in this conflict, it's probably not nearly enough.

They are likely reserved for last resort air defense closer to cities or areas where they really need to push back the Russian air force.

Patriot batteries are a bit on the expensive side, so their use is likely limited. If I am not mistaken, Ukraine did get a few batteries from other NATO countries and not just the US.

And it's about a mile? Many common rifle bullets will be starting to nope-out of supersonic around that distance, so you would need something really beefy, like a .338 Lapua or even a .50 to be accurate. (A bullet will generally start tumbling when it drops sub-sonic.)

Don't mistake me: many bullets can and do travel past a mile regularly, especially depending on the shot angle. Yeah, they can still kill. I am referring to the uncertainty and inaccuracy at those ranges, especially if a bullet has lost a ton of speed.

My main point is that long range sniper rifles are quite large caliber and generally require long heavy barrels. You aren't going to swing one of those around without being noticed.

The shot speed approximation is the easy part, believe it or not. Since the bullet must be a large caliber you can guess at about 200-300 grains for a "smaller" large caliber bullet, or between 650-900 grains for a larger one. (Maybe a few more, but I am sticking with a 338 or a 50.) Muzzle velocity is also going to be on the high end at between 2900fps and +3100fps for most all of them. The math is easy to work out with a common ballistics calculator by estimating the ballistic coefficient of available bullets in the category we are talking about. (Bullet speed at the target is the most important number to calculate.)

Still, it's not perfect math. If you look for a camera flash at an estimated time when a bullet was supposedly fired, you are probably going to find one, especially if you have a second or two of footage across multiple cameras.

Old 386 and 486 code was really easy. I also got lost around the Pentium era as well. At the time, it was getting really hacky to work through extended and expanded memory while also learning to work with 32bit registers.

At the time, correctly or not, I just felt I was learning to navigate a bunch of architecture bandaids and not anything that was going to be static for the next few years. I just kinda put it aside, TBH.

ASM is still useful for MCUs at times and developing that feels like the good ol days...

You can generally cross compile across architectures, but there can be instruction or build nuances that can cause hiccups. Also, you need to build everything against the target architecture as well, not just the kernel.

Undeniably there are similar swooping patterns but I think you are experiencing apophenia.

The layers are almost invisible with this tech. The custom adult novelty business will go crazy over this.

Several gallons (per day?) are allowed, for a little bit.

Sugar is one of the best anti-craving foods there is, IMHO. (I went from 185lbs to 215lbs in just a couple of months. I lost it all over the next year.)
