Yeah, I always check the Sold by Walmart box, and I need a good reason to go outside that list. It's just just about returns. Walmart does supply chain quality control that does not seem to happen as reliably on the 3rd party listings. (edited because I'm sure some 3rd party sellers are legit. target for example offers a selectable but short list of sellers, I imagine you could check them for reputation)

This isn't just Walmart though. Most non-Amazon websites have a similar option. Lowes, Target, NewEgg...

ocd reply to myself... s/just just/not just/

devuan also uses a stub fake libsystemd but it really is just a stub to avoid broken calls.

That sounds pretty foolproof so long as your black box fill method doesn't fill with a 99% opacity, or a flood fill leaves behind a few invisible anti-aliased pixels, or the merge operation of the black box doesn't result in some multiplication leaving a few bits of difference. Even if you erased the layer below, then filled above, I've had erasures vary in the bits outside the alpha channel messing up games using the texture info.

Overall, I kind of understand the paranoia even though in principle it does sound pretty foolproof.

Wouldn’t all those fears apply to printing as well?

The alpha channel ones would not apply to printing, and overall printing is an extremely lossy operation, where all those minute details get washed out in approximate ink levels and the muddiness of the physical world. It might not be totally foolproof, esp for a very accurate print process (don't use your photo printer maybe), but it's probably many orders of magnitude noisier..

I think if you're really concerned, you'd print it once, apply physical black tape on it (or cut out with a razor), then scan that :)

Printing would presumably have enough imprecision to mask those.

I suppose if the paint is the issue, glass bottles using the swing top metal hinge and rubber stopper method are fine?

They said corks are fine. For grolsch tops, the kind of rubber might matter, I'd guess.

Yeah, most rubbers today are actually plastics.

Natural rubber is also plastic. We tend not to call naturally occurring polymers "plastics", but natural rubber is usually vulcanized, so it is not that natural.

Natural rubber from tires is a significant source of microplastics (along with the other polymers the tire is made of)

I'm pretty sure tires are mostly synthetic at this point. I wonder if the natural rubber has a different safety profile than the synthetic, if it is more biodegradable, etc. Even traditional chewing gum fits the definition of plastic, but somehow it feels like it would be safer to use than modern synthetic plastic chewing gum. No idea if that's true

I kind of feel there'd be a difference between vulcanised tire rubber and my drink stopper, but I guess there might not be. Also, tires grating on road is probably a bit different a wear profile. Clearly someone needs to test microplastic shredding in container rubber.

Oh well, at least they have some in that design with cork tipped plugs. It's a bit harder to find though.

SMTP pipelining was actually the cause of fairly recently discovered vulnerability. https://sec-consult.com/blog/detail/smtp-smuggling-spoofing-... https://www.postfix.org/smtp-smuggling.html

Probably the main reason it is recommended against.

There's a couple of convenience approximations I use to work with US Imperial..

30cm is a "metric foot" (it's actually even closer to 1 light nanosecond which is kinda cool for thinking about distances at computer speeds)

250ml is a "metric cup"

I usually go with 240 ml if scaling down and there are fractions involved for slightly cleaner numbers.

Another "close enough" value is the binary inch of 25.6 mm. Makes dealing with /32s and /64s oh so much easier.

True. At that point you're close to the intent of teaspoons/tablespoons/cups with easier to remember units. tsp = 5ml tblsp = 15ml cup = 240ml

with all the handy halvings in between + higher granularity of ml.. 'course I'm usually approximating on a gramme scale anyway.

But for larger stuff I round up to 250.

Speaking of feet - I got irritated when buying shoes and trying to convert shoes sizes.

It turns out that UK/US sizes are based on the length of a barley corn.

Quite why it isn’t just in centimetres is baffling. https://en.wikipedia.org/wiki/Shoe_size

I'll give you this one, but only with the qualification that inches would be fine too. There's no benefit to the manufacturers in more rational standardization, though. As with women's clothing sizes, why would Levi's (for example) make it easier for me to find something that matches my style and budget, from anyone other than them? Hell, even men's sizes which nominally are in inches do this! I have to go a size up in Levi's vs Wranglers because Levi's size small, the bastards, while Lee mostly run true to size but none of their cuts is really worth wearing. And don't even talk to me about boot sizes!

Inches vs. centimeters? Baby stuff. Get on my level. :D

And now the famous triviality of order-of-magnitude and unit conversion goes entirely out the window...

That’s where duodecimal comes in…

Duodecimal metric! Tell me more.

You do what you can with the limitations of the system. Some rounding helps with a lot of feet/cups. 4 metric cups to the litre..

I would not count on a surge protector to save you if there was a direct lightning strike. Even a hefty UPS, but especially not the small ones in a power bar or some consumer electronic chargers.

Better to not have your laptop or phone plugged in at all when using it during a storm.

The case against Nacchio is a different one.

Article notes this impacts soldiers (or I suppose others trying to be stealthy) who would have turned off bluetooth and wifi.

If the transmission contains some identifying information and can be used for coarse triangulation to decide if a specific phone is in a specific building - well, that's pretty bad.

Can be harmful even without identifying information in situations where it's enough to decide if some building is occupied or not.

They mention android for this risk factor specifically-does android not have an "airplane mode" equivalent? I would assume it disables NFC also on iOS, but I guess I don't know —no mention of NFC on Apple's support page.

I’m the author. Let me clarify, as that was indeed worded rather vaguely in my post—I forgot to mention why exactly Android is at risk.

On the Pixel 7, Airplane mode absolutely did not disable those frequency spikes upon screen unlock. Only disabling NFC through the dedicated setting in the phone’s parameters did (Settings > Connected devices > Connection Preferences > NFC). This theoretically puts Android users at greater risk, since on iOS, Airplane mode does disable those polling signals.

It’s easy to see how an average user might assume they’ve gone completely dark by enabling Airplane mode on an Android device—when in fact, they haven’t.

I’ll update the original post with this information, and thank you for pointing it out.

Andoird has an airplane mode Once enabled airplane mode you can enable Bluetooth again and airplane mode stays on,so just no mobile data an.same is true for WiFi.

NFC however isn't touched by the airplane mode

...At least it was like that on the android phones I owned

Samsung Note (9 and 24 at least) has an "NFC and contactless payments" toggle (and a UWB one) on the page with wifi and bluetooth (Settings → Connections) but I don't know if it's "doesn't emit" or just "doesn't interact"...

From the article. "A great part of discussion in comments on the original thread I've made was about soldiers on the battlefield and a heavy usage of devices close to the line of contact. Android users might turn off Wi-Fi and Bluetooth and even remove their SIM card, thinking they’ve minimized their radio footprint. But NFC often remains active by default — and since most people assume it only matters within arm’s reach, they don’t bother disabling it."

> soldiers on the battlefield and a heavy usage of devices close to the line of contact. Android users might turn off Wi-Fi and Bluetooth and even remove their SIM card

I would think a faraday bag would be far more efficient for this - should take care of the NFC issue too

I'm assuming they're still using the phone in some capacity in (what they thought) was offline mode. What they really need are phones with hardware switches for all radios, which of course almost don't even exist as a product. If a faraday bag worked for them they'd probably be better off just removing the battery altogether when they don't need the phone (removable batteries also aren't that common anymore).

It speaks to how terribly fit for purpose mobile devices are for soldiers in an active modern battlefield. Not only do they require discipline and technology training to prevent leaking positions, but most of them actually lack the capability to prevent leaking altogether no matter how trained you are.
