Yes, that is generally/approximately correct. I'm not sure precisely how it's implemented on the public side, but you're placed into a seperate VLAN that enforces the captive portal. Traffic from the public WiFi network

I've been getting intermittent slow connections (30+ seconds to load Wikipedia) and SSL handshake failures for a couple weeks now. I thought it was just my old router. I had no idea it was more widespread. I was just about to start upg

Marriage does not mean both couples will be working. Conversely, you don't need to be married to be in a relationship with two incomes.

Only in airspace where a transponder is required. Most airspace in the US does not need a transponder unless you're near a major airport, and therefore doesn't require ADS-B. Aircraft without an electrical system are also exempt f

I built a Stratux and used it with Foreflight. Honestly, the reliability wasn't great. The dump1090 process would randomly disconnect, generating nuisance alarms from my tablet - usually in busy airspace. It also had trouble picking up

ATC isn't the only party who needs to see the aircraft IDs. As a pilot, it's valuable to be able to see tail numbers to help correlate what I'm hearing on the radio with what I'm seeing on my displays. I can guess who&#x

This is called "vasovagal syncope". [1] Certain emotional triggers, including the sight of blood, cause the brain to command the cardiovascular system to lower blood pressure. In some people this reflex is strong enough to cause

From a technical perspective, it actually is a bit of a problem. First, remember that speed is shared with everyone using the same tower (sector) as you. As data usage goes up, that will drop. In a major city where cell density is high it&#

Don't forget the 7% throughput increase on mobile. That's a big deal, especially given that mobile users account for the majority of network traffic these days. And 3% is still a lot if you're looking at global Internet traff

I see two postmarks. One stamped from 1920, and a second one sprayed on from 2020 (just to the left of the first one). The second postmark suggests that this was possibly redeposited into the mail somewhere.

There's something odd going on. I'm getting an NXDOMAIN error. It looks like I get different results depending on which DNS server I try: $ dig @8.8.8.8 www.privacytools.io (No results.) $ dig @8.8.4.4 www.privacytools.

FWIW, the few times someone tried to send me money via Zelle, it’s been a mess. Wherever email they sent was caught in GMail’s filters, so I never saw it. And you have to click a link to accept the payment, even from an established contact

You don't need to be rich to fly. You can buy a older used aircraft for the cost of a nice car. Sometimes cheaper. (Note: Not the Cirrus they're talking about upthread.) They're working on replacing leaded fuel. The challenge

There are manufacturer approved procedures for putting aircraft into long-term storage, as well as returning them back to service. Yes, there is absolutely additional wear that happens just from sitting around. Repairing this (if necessary)

"Four" was a typo on my part. I'm definitely not buying anything illegal. Sheesh. (Honestly, I think a money order would be terrible for this since they're traceable.)

Where do you draw the line? Is a company that manufactures mechanical pencils complicit, because they might be used as writing instruments at a coal plant? I agree that accountability is a good thing, and we need to be doing more as a socie

Yes. Rent is usually paid via check, and they're still useful when interacting with some government agencies via the mail.

Yes, you are. :) I have never had a landlord that accepts online payments. On top of that, most online services charge a merchant fee for business transactions - paying via check is cheaper for everyone.

I've used them for four main reasons: 1) You're paying for something already going through the mail (e.g. sending a form to the government). You can usually send a check, but some banks don't issue checkbooks anymore. 2) You&
