You can see that digital watches are superior by every non-aesthetic measure. Reliability, resistance to mechanical shock, timekeeping (You had one job!) , life before "charges", size, weight, life without maintenance etc. I found a digital watch I hadn't touched in ten years, and it was still running, and still close to the real time.

I wear a mechanical watch (Bremont F15 watch) as a kind of fancy-dress jewelery. It's a fashion / social thing. As a tool, it does not compare favorably.

Network-connected application developers have as a community, desensitized me to this. They are the Boy Who Cried Wolf. Continuous mandatory updates in the name of security. Guilting you into thinking each update is critical due to "security".

I don't care. It's a hassle, and I don't believe the threats they warn of are something to warrant my attention in the landscape of things I should worry about in my life. Anecdotes don't help. To overload with another analogy: Security is a "think of the children" or "full stop": it's a thought-terminating cliche, and I don't believe people who use it.

I am using my own combination file browser/terminal. I landed somewhat arbitrarily at the each tab has its own CWD (PathBuf field), ie how terminals do it. Not the only right answer, but has not been a blocker, and simplifies some things knowing there is [for that tab] a single CWD which can be used to manage bookmarks, assess if the we're in* a git repo, rust project etc.

This approach may present limitations later; will change A/R. But simple = good for now!

I should clarify: I'm referring to Amazon (prime or whole foods), which I understand is significantly cheaper than Instacart. It might be worth cross-shopping in this case.

I suspect this as well. Enjoying it while it lasts... I suspect the facilities being vertically-designed for this helps, but not enough(Especially the prime groceries; I suspect Whole foods has some but not the same extend?)

Do you find it, total price charged to card, to be competitive? What if you already have a Prime membership?

Takeout and prepared food delivery is much more expensive than grocery delivery.

Valid!

IMO grocery delivery is a game changer. I don't use either service, but use a different one[s]. Even with a tip (I have been doing $15/per delivery), it's not much more expensive than normal groceries at Trader Joe's etc, and I don't have to put on outdoor clothes, walk to my car, navigate traffic, navigate the aisles, wait in line, reverse... IMO big QOL of life increase.

And second-order effects like I can always have fresh fruit + veggies / not worrying about rot by getting it in smaller quantities delivered more often.

For those wondering about price: It's much cheaper than takeout or prepared food delivery, but more expensive than getting your own groceries. Offset a bit by less food waste.

Hey - dumb question that is probably a derail: Is there a practical reason in the US to use Instacart over one of the Amazon services? It seems like they are fighting an uphill battle - Amazon has its own grocery warehouses (Prime food), and owns Whole foods. I haven't cross-shopped recently, but am having a hard time imagining them competing on price with either of those services. I suppose the obvious reason is you aren't limited to those two stores, so if you want specialty items, nice baked goods etc you would use Instacart?

AHH. Definition 1.4 and the questions after did it. It went from "Tracking all" to "I don't understand how this follows at all, and this makes no sense to me" 1.3b is a graph, not a union of two graphs?. What are the "two graphs"? What is this operator-like algebra, and what does it have to do with the rest of the definition or the text before and after it? A question about the complement which was never defined? Why are we probably agreeing that {1, 2} contain 3?

Update: Better phrasing I can understand:

"Definition 1.4. The union of two graphs G and H, denoted <>, is a single graph containing all vertices and edges from both. If G and H share no vertices in common, <> is a disjoint union."

For 1.5, I had no idea what the written definition meant, but this does: ``` Definition 1.5. The complement of graph G is the one that has the same vertices, two vertices are connected in G_complement if and only if they are not connected in G.

Downside to this: it takes a long time, I have to source the parts myself, and I can't separate design or programming errors from soldering errors. (There will be many of those) I have not figured out a system to So: Having JLC do the assembly is a no-brainer for the projects I've done.

OSHPark is a nonstarter for many workflows because they don't do assembly. I can't do anything with a plain PCB!
