On the other hand, QR code payment systems only work while the user has a good network connection. NFC payment terminals can work while the user's device is offline, like rural areas with poor cellular coverage. Not to mention tap-and-

If you're on a metered internet connection, that's still 500 MB/month the user is paying for without consent.

There are certain file formats that are explicitly designed to be archival safe, like PDF/A. For long term stability, I always try to export a copy to one of those. File formats like .doc or .psd that are tied to evolving product lines

That could be a lot of things, including sleep apnea. A formal sleep study is a good place to start.

Eating foods high in glucose seems like a good way to give yourself insulin resistance and diabetes. That does not seem like the answer.

Out of curiosity, what areas did you find were the most challenging for your students?

Now that you mention it, I could see MSFS being useful for general area familiarization. Foreflight has 3D mode now for the same purpose. But MSFS would certainly be more fun, and an instructor could mix in other navigation skills. It would

VFR students shouldn't be anywhere near a simulator, imo. Primary training is all about stick and rudder skills, which you can't pick up in a simulator. The feel of the controls isn't even close. (I guess you could use a simu

As I understand it, only one company makes the generic right now. As others begin producing it market pressure will hopefully drive those costs down. It’s also worth noting that some insurance companies have recently begun classifying it as

Gilead's patent on Truvada (the most common drug used for PrEP) just expired. As of a few months ago it's available as a generic.

Yes, that's correct. After entering a CD4+ cell, HIV uses reverse transcriptase to copy it's RNA into DNA, enters the cell's nucleus, then uses integrase to splice that DNA into the host cell's genome. From that point on

The Internet permission was largely useless. If you knew what you were doing, it was trivial to bypass it to exfiltrate data. On top of that, almost every app requests it, which contributed to alarm fatigue in users. Permissions are only us

It depends on which desktop client you're using. Telegram's native Mac app ( https://macos.telegram.org/ ) supports E2E-encrypted secret chats. Their cross platform Qt-based app ( https://desktop.telegram.

Telegram's UX is outstanding. Their E2E encryption (for "secret chats") is also questionable. Both are simultaneously true. It depends on your needs. I use Telegram like an IRC client, primarily participating in medium/l

Does this apply to users on T-Mobile's network via MVNOs, or only customers who subscribe directly to T-Mobile?

This hasn't really been true for a couple years now. Most of the major US airlines have been migrating from cellular to Ka- or Ku-band satellite internet over the last few years. (Including Southwest.) There's some individual airc

In aviation you want to avoid unnecessary complexity. You really want to avoid single points of failure. Most small aircraft are controlled via cables and pulleys because they're simple, can be redundant, easy to verify, and unlikely t

The standards for a FAA third-class medical go beyond just what's on the official "disqualifying" list. It's not a walk in the park. From personal experience, they care a great deal about your eyesight. To start, you&#x2

"Declaring an emergency" isn't even correct in the US. The FAR/AIM only lists "mayday" and "pan pan". (Yes, it's oddly common here in the US for some reason. I think some pilots are afraid to say

Even client-side apps can link to lots of proprietary dependencies or require internal tooling that a company is not willing (or sometimes just not staffed) to opensource.

And with a tri-fuel kit, you can run that generator on gasoline, propane, or natural gas depending on what's readily available. Even if the gas pumps are offline due to a power outage, you could hook up one of those prefilled propane c

The simple reality is there’s no economic reason to do that. That $350,000 goes towards staff, facilities, and research projects. If they had the choice between funding new cutting-edge research or migrating some obscure legacy code, the ne

This looks great. It’s so hard to find an inexpensive antenna rotator. Do you know when the project files will be available to download? I’d love to try making one.

It's worth noting that the Unifi gateways have hardware offload for traffic routing. While a Raspberry Pi might work for some folks, it's worth noting that these are two very different performance classes.

At least with Comcast Business, I never had this problem. I used my own modem and router, and the few times I had a line problem they just asked me to connect my laptop directly to the modem with an ethernet cable to troubleshoot.

Having vulnerabilities is never great. However, this is a separate issue from whether the PDF reader explicitly allows code execution or supports some of the more obscure PDF extensions, which is what the parent was talking about.
