I thought that was crazy, but reflecting over my CS education they haven’t gone over the difference between disk space and RAM. I suppose they figure everyone already knows?
You sure you didn't have a computer architecture course? Most CS programs it is a required course
I did (actually it was last semester) but they didn’t do basic definitions, it came with an assumption you knew what the parts of a computer were.

#163iOS share password functionality has really simplified things for guests. This is a neat idea for an AirBNB or similar short term rentals.
The QR code seems to have the same amount of friction as the share password. It's something a guest can do asynchronously without needed someone else to do something.
Also, I like the use of guest SSIDs. My guest SSID is just like my main SSID but with L2 filtering for all traffic not going to the gateway. Guests can use my fast internet, but just not interact with my LAN or other guests. I also don't enforce WPA3 only on my guest network for legacy support.

There is no real specification. This is the best source[1], which documents QR standards. >There are some standards -- de facto and otherwise -- already in use. This wiki attempts to catalog some possible standards for encoding various types of information, and suggest a standard action associated to them.

Damn, that's saddening, but also answers a question I had about what the escape character is for a password containing `;` -- I guess there's no specification to tell me :-( OTOH, I guess a "standard" is whatever the common implementations accept anyway, so if one could dig up the source to the WiFi QR scanner in source.android.com that's the 2nd best thing
No specification, but the linked website mentions that they “propose a syntax like "MECARD" for specifying wi-fi configuration” and then later:
> Special characters \, ;, ,, " and : should be escaped with a backslash (\) as in MECARD encoding.

#165My iPhone has a pre-defined "Make QR Code" "Starter Shortcut" that you can invoke by typing "Make QR Code" in Home screen search. It basically generates a QR code of the same WIFI:S:$SSID;P:$PASSWORD;; format as wificard.io. https://en.wikipedia.org/wiki/QR_code#Joining_a_Wi%E2%80%91F...
What? That’s awesome I had no idea that came built in! Pretty cool!

Seems to be using the same format as https://qifi.org/ , which lists supported devices, but of course due to the lack of native QR on most Android devices it's per-app rather than per-phone.
It's 2021 and Android still has fragmented QR scanning.
I don’t get it… is it that every single android oem makes their own camera app? Or did google choose to just not have barcode/qr code as part of the default camera app?

Answering as the author who also understands the fundamentals of all of the technologies involved and questions much of what goes on in the minds of today's web developers and designers-- I use Make as the standard way to interact with every repo I own. This allows me to type `make build` instead of `$some-language-specific-command-I-forget-in-2-weeks`. I use Docker for distributing every app I build. If the app is a…
But now you’re paying for keeping a server online, whereas a GitHub page could’ve hosted this static website for free.
There's no reason that this would have to be hosted on a traditional server.

#169Cool! I wonder if we can generate QR code for WPA2 Enterprise with EAP-TLS?

My first though was "Why would I ever enter my wifi credentials into a web form?", but perhaps there are people who would...
