High-octane unleaded. There's a couple options that are being tested right now.

by tjohns 6y ago
The problem is there hasn't been a suitable 100-octane unleaded replacement until very recently (see: G100UL or UL102), and lower octane fuels cause detonation. Last I checked, how well the replacements perform is still an open questio

Is this common for universities across the US? The university I went to (USC) required that all students had to either submit proof of insurance or pay additional fees as part of their tuition to join the university's health plan. Not

I'm curious if this impacted the Foreflight development team, since they were recently acquired by Boeing. I'm really hoping not, since Foreflight is my favorite app for aviation and up until now has been doing a great job of addi

My Samsung 3D television was awesome for playing PC video games on. The big downside was that playing PC games on a large television wasn't the most ergonomic experience. (And for movies, none of the streaming services offer 3D content

I have seen a few at airports outside the US after we switched to millimeter wave. So yes, they are used in other countries. (And unlike the US, opting out sometimes isn’t an option.)

It’s worth noting that single engine FIKI is a little controversial. Having TKS (or boots) is definitely a safety benefit in case you end up in inadvertent icing, but remember that the system can still get overwhelmed. Avoiding icing condit

It's the history behind the brand that's important. Does that company have a history of building quality products? Do they support them when something breaks? What kind of reputation do they have? When you buy a brand name product

Because after 12-18 months, we'll hopefully have a vaccine and won't need to resort to an antiviral drug anymore. At least assuming people get vaccinated.

Radio spectrum is precious, so virtually any type of radio telephony is significantly compressed, either in terms of raw audio bandwidth or by applying lossy digital compression — often both. This applies to both 2-way radio and cellular te

Yes, once your call gets to the central office it's moved onto a digital connection -- essentially an ISDN line. Notably, the entire telephone network is standardized on G.711 as a codec, which is raw PCM audio at 64 kbps, from 300–340

by tjohns 6y ago
While G.711 is uncompressed (it’s the same codec used within the PTSN backhauls), it’s still not great for fax because the fax protocol doesn’t tolerate the jitter introduced by VoIP. (Reliable latency is the one big benefit to switched net

In rural areas, Uber can be downright expensive. In my hometown, Uber easily charges $30-45 for a quick trip across town.

You have to use the Wireguard client. In that regard it's similar to OpenVPN. Wireguard uses a custom protocol that isn't supported by Windows' built-in VPN client. Most OSes only natively support IPsec/L2TP or PPTP.

It's not like there aren't other options out there they could be using. I'm sure this was factored into the decision given current events. At this point, I think it's more than fair to be worried about Zoom's securi

There are VoIP providers that are incredibly cheap. As an example, I have an account with voip.ms. They charge $0.85/month for the phone number, and then $0.009/minute. (E-911 service costs a little extra.) It's worth it just

From what I read, it seems there was a cache of N95 respirators in the Strategic National Stockpile. However, it was depleted during the 2009 H1N1 outbreak and never replenished. Instead, their budget was used for what they thought were mor

That is most definitely not what the court order says. She was dismissed because the Grand Jury had concluded today, and therefore her testimony was no longer required. The suicide attempt wasn't even part of the discussion.

Miracast never worked very well, in my experience. I don’t know where the failing was, but it really only worked reliably when the compute device and TV were from the same manufacturer. Cross-vendor compatibility was hit or miss. (It also d

For what it's worth, the FAA has been pretty explicit that they don't want drones on ADS-B. There's not enough bandwidth. They have a proposal to create a parallel tracking system just for drones. It's created quite the

I think you have an incorrect understanding of who owns planes. You'd be surprised how many of your neighbors own or rent aircraft at your local GA airport. It's not just something multi-millionaires do. In many cases it's ch

Personally, requiring a public address for amateur radio is a big problem and I'd argue needs to be changed. It makes you a target for doxing and swatting, and causes an unending amount of spam mail that you can't unsubscribe from

First, airplanes come in a lot of different sizes, and many don't cost anywhere near millions. A quick search online shows that you can find a used Cessna 172 starting at $35k - and is about the same size as a car. Second, just because
