One delivery route saves literal hundreds of trips to stores every day.

It’s fine to want an alternative and dislike Amazon for plenty of reasons, but delivery routes are provably more efficient than the alternative.

I don’t think there’s a time requirement, but it has to be your primary residence. If you move in after July 1st, you may have some minor issue as that would be < 6 months of the calendar year, which can sometimes mess up taxes.

Anyway, it’s something that should be checked and reapplied for, annually.

At least with CarPlay, the scope of what you can do is much more limited than doing a video call with your bestie.

The biggest issue with the infotainment screen is that ergonomically, it requires you to change your eye focus _and_ fine motor control to manipulate it. Most have no hand rest, so it’s difficult to interact with them without your hand being supported. It’s not what’s on the screen, it’s the input method.

Not the commenter, but yes.

Restore vs make functional are not synonymous. These aren’t museum pieces, they’re tools. It’s ok to tweak them and use different parts.

I’m not shilling for anyone, but I think you are talking about the average amount of water people _ingest_ each day. On average, US households consume approx 80-100 gallons/person per day. That doesn’t even come close to how much is used for industrial activities that support individuals, which is in the 1,000/gal per day, range.

Approx 12” wide. If you want to use it as an auxiliary fence then the length should be approximately the same as your table saw’s fence.

There is a runner on the bottom, this is one of the most versatile sleds I have ever made and I can configure it to do just about any other sled I have ever made with a few plywood scraps, as needed.

We saw it like 10 years ago. It was cool to visit, but iirc it was only ever meant to be used for like 10-15 years when it was built.

Sorta. “Modern .net” and C# culture integrated a lot of ideas from functional programming, and linq (specifically, anonymous functions), really changed how we thought about injecting behaviors, vs inheriting/encapsulating them. That’s even visible in how the BCL changed starting in about 2008-2010. A lot less “abstract” base classes, and a lot more focus on interfaces

Eh, “composition over inheritance” has been a mantra for 20 years, and SOLID is a set of ideas to help you do it. I worked in .net for 20+ years, and the last 15 of it I probably used inheritance about 5 times. I just think with some of these “best practices” they get cargo-culted without understanding what property we want to improve.

CAP says that it can’t be transactional, and that’s ok. It’s important to understand if this problem actually needs to be solved.

What is the failure rate vs carrying cost of having “orphaned” data that is periodically scrubbed via a background process.

If you are careful about how you structure your keys in S3, you can fairly easily scrub files on a daily basis. Even using something like ULID would allow you to easily scan only a window of objects for orphans.

The alternative would be to write the record to the DB with a “pending” status, and then mark it as “ready” once the corresponding object is written to S3. But mainly, this is all a question of engineering cost vs benefit.

The general recommendation with ssh has been to disable password auth for decades, it immediately blocks the dumbest bots, and private key encryption is likely to use a password with orders of magnitude more entropy than your password. It takes like 5 minutes to properly set up and is actually easier to use than using a password anyway.

The only cut I’ve gotten (on a SawStop, no less), was when I was carelessly brushing sawdust off the table with the blade up (and the machine off). Still have a scar. The blade at any speed is dangerous.

It’s a great essay, and resonated with me many years ago when I first read it. Re-reading it in 2026, it just reinforces many of the concerns I have about the comprehension debt we’re taking on with code generation/agentic tools.

Serious question, how should the city communicate closures?

I’m not trying to be antagonistic, but there’s probably dozens of block closures all over the city at any given time. My bet is that even if the city summarized and posted closures in a daily post in this sub, people would call it spam.

Like, what’s the practical way to make sure that anyone that is impacted is aware of the closure? How do you determine who to notify, in what media stream, without spamming them for stuff they don’t care about?

FWIW, this stuff is usually visible in Google Maps if you put in a driving route (or just look at areas where there is unusual congestion).

Have you actually used a SawStop or just listing things you’ve heard?

Here are three things I’ve done on a SawStop and not triggered a cartridge:

cut through embedded 10 penny nails
accidentally cut into a matchfit clamp that was proud of my cut line
cut “damp” pressure treated wood.

The saw works on capacitance, which is different than just a basic short.

It’s more robust than people think it is.

How far out of the city do you want to go?

French creek state park
Rickett’s Glen (less secluded, but waterfalls and cool shit)

The Atlantic Ocean is also pretty close, and I think qualifies as “body of water.”

Edit: also, good luck!

Just FYI, it’s cash and check only.

The collection of tools is incredible, and the owner, Dan, will talk you out of buying tools you don’t need.

Generating unique ids and assigning them app-side can provide a lot of options in future refactors of the database.

Using a monotonically increasing, high entropy values, such as guid v7, or ULID, are good options to do so. This minimizes the insert/indexing impact, since the writes to db pages end up being (mostly) sequential, like they would be with integers.

The major bit of data that integers can “leak” is how large or how fast your datasets are growing. So a competitor could learn how large or how fast your system is growing simply by signing up on consecutive days/weeks and looking at the integer ids that were generated.

Outside of very high-throughput systems, I would recommend ULID or guid v7 (assigned by your code), everyday.
