AirDrop doesn't open a network port, it creates a WiFi Aware advertisement and a WiFi Direct connection. However I thought this also should not need OS-level changes, just android.permission.NEARBY_WIFI_DEVICES permission.

Each level on the chart has 10x the bandwidth of the level above it. It's not really that much spectrum.

Expires header in the past seems suspect. And all the header names are lowercased.

If you really need a lower tier, you can switch currencies to JPY, there's a monthly option for 500JPY which is about 2.67GBP.

I think that's rather high compared to average, considering the standard cap for Comcast Xfinity residential is 1.2TiB per month, and they claim only "a very small percentage" of their customers use more.

I don't think the actual cap really matters if the per-GB and base pricing reflects the true costs. If it's low it means heavy users pay more, if it's high, light users pay more.

If ISPs were like an electric utility, we'd see something like a cost per GB transferred in cents, with a minimum charge reflecting the cost of maintaining a connection of a certain speed to the network.

Which is algebraically identical to a monthly charge and data cap with overage charge. The main issue is the overage charge is too high, it should be like 1 cent per GB (Comcast is charging 20x that).

you are (mostly) agreeing (except for precise definitions of metallic and ceramic). Their comment is unclear, but it means

"In almost all applications of superconductors, they don't use high-temperature ones. [...] The ones [the superconductors] that see use in the LHC, for instance, aren't [high temperature superconductors]."

It just has a sentence in the middle of it that confuses you into thinking their antecedents are "the HTSCs" and "ceramic" instead of "the SCs" and "HTSCs".

Is this a common slang in infosec? I've never seen it used like this and it has highly insensitive connotations for me in other contexts.

I see a lot of comments mentioning "residual keys". Is that the same as the "resident keys" the article talks about?

Yelp's stated policy is to remove reviews by people who didn't actually directly interact with the business, regardless of the content.

It doesn't unhack a hacked 3DS, it just closes an exploit used to hack it in the first place.

So I would add custom firmware first if that's something you want to do to it in the future.

This looks great, except I have a lot of linux devices, which doesn't look supported. Currently I'm often avoiding my app/website blockers by switching devices or browsers.

PFAS is a class of chemicals that includes both the safe/stable PTFE and cancer-causing ones like PFOA, PFOS, and new ones

I did not realize this. That seems rather unnecessary.

PTFE, the end product, is safe for general use. PFOA/PFOS were used in its manufacture, but does not need to be present in the final product or dumped unprocessed into the wastewater or landfill. It's only in our environment due to cost-savings reasons.

I know many will want this covered by Nintendo out of principle, but it is a very easy fix to perform yourself for the average hacker. The parts and tools are inexpensive as well. I have replaced 5 joycon sticks now and I find it rather satisfying.
