How do software updates happen?

[Silicon Desert]

RFC1912 explains why:
" Allowable characters in a label for a host name are only ASCII
letters, digits, and the `-' character. Labels may not be all
numbers, but may have a leading digit (e.g., 3com.com). Labels must
end and begin only with a letter or digit. See [RFC 1035] and [RFC
1123]"
....

"There is at
least one popular TCP/IP implementation which currently refuses to
talk to hosts named with underscores in them."

In a different career, many moons ago, I tripped over EXACTLY this. The powers-that-be built early Exchange servers with underscores. Because that's not legal, the _ is changed to a dash when using DNS. This gets horrifically messy, when the server thinks its name is EXCH_01, but sends email from EXCH-01.domain.com
See: Best Practices for WINS Servers

Many SSL certs enforce RFC1123 as well: Underscores not allowed | digicert.com

In practice, it works for the most part.. but anywhere the RFCs are enforced somewhat strictly, you could get some very interesting edge cases.

Been there, done that, managed the email system for 100+ million customers ....

Hostnames themselves cannot have underscores, but other record types may. See: Hostname - Wikipedia

ah, nice info. Glad to know I am in fact doing it properly for my host names.

They're not just strange, they're not legal in a hostname.

I can tell you exactly why I know this, but let's just say it involves Solaris, Sendmail and Microsoft Exchange.

Sounds like fun. Lol. Solaris is how I first learned Unix many years ago.

Took delivery of a new M3P yesterday. Software for a car BUILT a week ago is an older version of what's currently available. How can that be? When I asked the person at the MDR delivery center, he did not know the reason or the answer. When I mentioned that I'm entitled to faster updates, according to Tesla website, he had no answer for that.
Is there a way to request an upgrade to the latest software version????

thanks

Service from Tesla is not good . And good luck if you even revive any answer on anything.

You can select “advanced” in the software control panel. That would add you to the first pool of installations. There is a lot to learn with a new Tesla. After owning it for a week or two rereading the manual is surprisingly informative.

Then there are the release notes from updates. It seems like it takes about three to four weeks to update the “fleet”. The queue exists and thousands of cars are updated daily during rollout. A new car needs owner activation of cellphone key, full setup on Tesla.com and probably geographical registration. It seems to take 7-21 days for most new users to get their first update. The common reply on the forum is “chill”, it comes when it comes. I bet searching the forum for the work “chill” hits hundreds of threads.

Enjoy the car, it updates itself nearly monthly.

(Ok, confounded with “chill” mode but only about half...)

I still have a lot of customers that rely on SPARC and Solaris for anything mission critical. In fact, I’d guess you’ve used it today (without knowing, I’d course.) They’re still buying and growing.

Solaris 11.4 is amazing. Every time I have to touch Linux I keep feeling like I wound the clock back 20 years. Containers (zones), boot environments (ZFS snaps), systemd (SMF) are all reimplementations of stuff Solaris has been doing for years.

anyway, I digress ......

I hope that's true because I live in an apartment building and the garage is underground and I barely get a cellular signal down there.

My car was on LTE when it got the emblem/message about an update being avail. (I was at work).

of course it wouldn’t download until I got home (Wi-Fi)

How long do the downloads take?

I picked my car up yesterday. Model 3 performance. I asked the delivery specialist about not having wifi and if that would be an issue. She said I had the LTE connectivity package so I'll get the updates through that. I'm on 2019.27.103 right now. We'll see what happens. But I'm guessing I'm going to have to pay to use my phone as a hotspot.

Thank you for that information! I've been connecting to my phone's hotspot while I drive haha, but I haven't received the the notification. It's good to know I don't need to fret about the lack of wifi though! This upgrade process is like playing video games and waiting for the random number generating gods to bless you with the good loot.

Patience is definitely key, I think my update has finally started to download. Even though I don’t have anything on the app telling me it’s time to update or download.

It has. You’ll get the popup on your app once the software’s fully downloaded. That way, when you click the button, it actually executes the update.

Thank you! This is my first update haha, so I wasn’t sure of the logistics.

ok so listen ... when it’s doing the update. BE PATIENT!! It’s going to click and clunk and you’ll get horrible scary messages on the display. It’s all normal.

best to do the update when you’re NOT in the car, to avoid all that.

it’s going to say 25 minutes. That’s in Elon time - it’s going to be closer to 40.

Just go get a drink, relax and give it time to do its thing!

It’s about to go down!
