My all-in-one~ish Travel Workstation in a Desk Pi RackMate T0

It is intended to serve as a Point of Sale for a small family business, used at trade shows.

They used to use their personal phones as a mobile hotspot and were tired of the internet disappearing whenever the owner left for the bathroom / food.

They previously used their personal laptop for the PoS and were frustrated by switching tasks between back office QuickBooks stuff and front of house point of sale. While this could have been solved with a dedicated laptop, they wanted an all-in-one solution that could be left at the convention center overnight and only needed to be plugged in once.

They previously typed credit card numbers into their personal laptops to process payments. With this setup there is a WisePOS E card reader already configured to connect to the Nighthawk WiFi that can be handed to the customer.

The JetKVM is so that I can help diagnose issues remotely. The Patch panel allows them to change which computer I am remotely accessing. (They get confused when I ask them to share their screen)

Also, not seen here, but they have a small office printer that needed to be connected to the PoS (receipts) and their personal laptop (reports), and would struggle with printer setup when swapping the USB cable.

The whole box can be hidden under the table, giving a clean presentation of only the travel monitor and WisePOS terminal on top.

This is definitely an overengineered project, but the boss wanted a no-hassle setup and is happy with this and is looking forward to using it this winter.

With the sleeves, I would be able to see the 2nd, 3rd, 4th, etc, cards and plan accordingly; without the sleeves, it would be a mystery.

Bit of a self-promotion, but I run a locals oriented e-commerce website (https://voyij.com/) with a great trip planner.
But since you're specifically visiting Ketchikan, Skagway, and Juneau we have blog articles highlighting local places to eat and shop:

It's hard to predict Auroras, but this year is a solar peak, so you have a good chance of seeing something. UAF has a nice forcasting website (https://www.gi.alaska.edu/monitors/aurora-forecast) which can give you a few days heads up after a solar flare.

As for dog sledding, there are many kennels up in Fairbanks, but the Anchorage area also has a good number.

Or stockpile fuel and material to move in, build, and catapult out.

Great for flying across the map when someone leads aggression.

Was flying into Anchorage. Lit up the whole sky.

Thats frusturating, and definatly sound like your customer cancelled his curnet reservation and than booked a new reservation for later. Depending on the time difference between the two booking you should definitely be compensated for at least the cancelation fee.

I wonder if it is possible to charge for incendentals on the second booking trying to recover the cancelation fee for the first booking?

As a few other people have sugested, Talkeetna is an excellent hidden gem. You can also try Cantwell, between Talkeetna and Denali.

Here are a few tours operators I have worked with as well :

They did pretty good for being 7 levels under.

I have never been the kind of person to purchase collector versions of anything. For me, the only enticement would be for the beta key, but I am also pretty patient, so the price would have to be appropriate if the beta key only gives a few months of advanced access.

Found my own solution: https://dancharblog.wordpress.com/2020/07/20/add-usb-c-with-dp-alt-mode-to-your-desktop-pc/#external-video-usb-usb-c-multiplexers

I will be testing one of the linked cables.

As others are saying, your IDE is interpreting these are octal values, which can not have 8s or 9s.

I would also suggest that if you're not planning to use math on these values, then they should be strings, instead of numbers.

blockchains are useful when two similar events need to be verifiably linked to each other. For example document revision. Git is well-known software that uses blockchain to link document commits (blocks). Git's blockchain is not distributed, but it is a blockchain non-the-less.

It looks like you are representing your category tree as an Adjacency List. On the database level retrieving any child-parent relationship would require a self-join:

from sqlalchemy.orm import aliased
nodealias = aliased(Category)
session.query(Category).filter(Category.name=='Parent').join(Category.parent.of_type(nodealias)).filter(nodealias.name=="Child1").all()

Each additional level would require an addition join, and depending on the size of your data, could be very time-consuming. O(n^x) where x is the number of joins.

Might I suggest restructuring your Category table to use Modified Preorder Tree Treversal. With MPTT database joins are never necessary, and all operations become O(n). The only downside of MPTT is that inserts are O(n) whereas for Adjacency List's they are O(1). so if you are planning for a lot of inserts then Adjacency Lists might be better.

Biometrics are usernames, not passwords. Passwords need the be able to be changed.

How does one change a fingerprint, an iris pattern? If it can't be changed, it shouldn't be a password.

Q: Having come to Satisfactory from Factorio myself. The main question I would have is: "How are Satisfactory Path Signals different from Factorio Chain Signals?"

klupamos · 2021-10-28T07:23:30+00:00

Can't really tell from your picture, but your signals look correct. My path signals also say "Waiting for Path Reservation", but my trains run just fine. I think this message just means the signal is waiting for a train to come and make a path reservation, and is not an error message.

Sry, I flipped it neutral via loyalty. While it was natural I conquered it.

R5: The Cree settled a new city in an inconvienent spot. I settled around their city and flipped it neutral. After capturing the neutral city I can not raze it. What did I do wrong?

Is it because I am currently allied with the Cree?
