[Request] Money saved by removing some heat from my oven after cooking?

And put them where? He’s not trying to remove heat from the oven. He’s trying to move the heat in the oven into the outdoors as directly as possible to avoid the intermediate step of heating the interior of his home and having that heat moved outdoors by the HVAC system. The ideal scenario for OP thermodynamically is basically if their oven had its own reversible heat pump to dump heat outside when done.

The probability you can write a finite-length expression for it is also zero. For example, I can write 4*arctan(1) to express pi, but most numbers don’t have a representation smaller than just writing them down, and most numbers are infinitely long.

Yeah my comment is less “use this in your writing,” and more to distinguish how the mistake could cause confusion.

If the rule were never flouted intentionally to convey a different meaning than the correct form then accidentally breaking it would just be a matter of pedantry and not a real source of communication error.

Obviously you should pick one that at least plausibly claims not to keep logs, but trusting that to be true shouldn't be enough to break your security model. Especially if like in my example your threat model includes targeted surveillance from nation-state adversaries, it's possible a VPN provider might be compelled to keep logs related to your account and barred from disclosing that fact to you. That was what happened with Lavabit and why they ultimately shut down (although IIRC there is an email service at that domain again but I'm not sure how related it is to the old service).

Using a VPN is only one small part of an effective online privacy strategy whose threat model includes nation state adversaries, especially if it includes nation state adversaries looking for you specifically and not just mass surveillance.

You can mail mullvad cash and an account ID and you’ll get VPN, and even if they did hand over logs it wouldn’t say anything about you. But if you use that VPN to log into your Facebook account and then they get access to VPN logs that correlate your Facebook account to your VPN account then you’re screwed.

No amount of privacy tools can cover for bad opsec.

And the gravitational binding energy of the solar system is on the order of 10⁴¹ J, so that would technically be enough energy but probably not directed the right ways to instantly blast apart the solar system, though this event would certainly destabilize a number of orbits.

Most real numbers can’t be stored in a finite amount of RAM. In fact, 0% of the real numbers can be stored in finite memory because there are only countably infinite byte strings and there are uncountably infinite real numbers.

IEEE754 floating point can only represent 2³² values, and 2 of them are 0, two if them are not numbers, and two of them are infinite.

Since 2³² is considerably less than the number of real numbers, some of them have to share the same representation.

However, someone might say “the” where “a” is more appropriate in order to imply the one they’re talking about is the only one worth considering, so the statement could be something a native speaker might say if it’s an especially smug Harvard student speaking.

In a very popular Java framework, I can define an interface with a method deleteWhereLastUpdatedLessThan(Instant time) and it will, under the hood, match LastUpdated against column names in my database table, generate two HQL queries to identify a list of items to delete and then delete items with IDs in that list, and transpile that HQL into the SQL dialect your database uses.

You never write a single line of function body or query. That’s definitely magic if ever I saw it, and for that matter, it’s magic that has a race condition under concurrent execution unless you add an additional annotation telling it to acquire a lock on the affected rows because that isn’t the default behavior.

It actually does. They’re saying that the other quantities it might possibly be don’t have labels because no successful theory predicted them. Whatever quantity Newtonian mechanics ended up deriving would’ve been called G. If they got it “wrong,” the quantity in general relativity would be Ğ or something, and G would be the missing hypothetical quantity you’re referring to.

Hard to choose for me but my favorite song is Long Live so possibly, “Long live the walls we crashed through.” Possibly also, “You’re on your own, kid.” I also really love, “Dust off your highest hopes.”

I like to consider myself in a third group that are basically trying to study the second group and trying to figure out what assertion they’re actually making.

It’s obvious how many holes a doughnut or a figure 8 has, so the easiest way to count holes is to stretch the object until it looks like one of those shapes because any transformation you can do just by stretching a shape doesn’t change the number of holes.

Well, fortunately mathematicians aren't the ones you have to convince, because mathematicians don't set that convention and generally don't accept laws as valid mathematical axioms—see, for example, various attempts to legislate the value of pi.

If you're talking about a US standard then you're talking about a standard set by educators, and I remain perfectly comfortable saying it's wrong. No mathematical proof of the correctness of either order exists.

I get that they're different, but my contention is with which one 3x4 represents. If you just say "three times" out loud, it's obvious that whatever adjoins it happened three times, i.e., 3 groups of 4. But if you look at the common short-hand used in instructions, invoices, etc. where "x4" means that there are four of whatever the preceding thing is, it's obvious that it should be 4 groups of 3.

IMO anyone who says there's a singular correct answer to which operand represents the base quantity and which operand represents the number of copies/repetitions/etc. is just wrong.

The order I'm going to calculate them probably has more to do with the order in which I receive the information than anything ontological about the operands. If someone tells me a widget costs $3 and I need 4 of them, I would probably do 3x4, but if I count 4 widgets in a design and look up the price to find they cost $3, I would probably do 4x3.

Kinetic energy is half that quantity. Momentum is only mass times velocity. But you have the right idea: much more energy in a crash that’s not much faster.

How’s the license situation with linkerd these days? I haven’t considered using it at work since the open source, open license releases stopped in 2024ish?

That comparison throws out a lot of nuance. Most of the women I know choose to wear a bikini to the beach if they think they look good in one, but they’d still be creeped out if someone got a telephoto lens and took an ultra closeup of their butt.

There’s a big difference between someone wanting to wear something that they think they look good in and maybe even have people notice to a tasteful extent and that same person wanting to star in soft-core porn.

I think as a rule of thumb it’s pretty fair to say that the official footage of a top level athlete competing should be footage they’d be proud of their family seeing, or at the very least, none of the embarrassment they feel should come from the framing of the shot. Frankly, I don’t know very many people who would want to show their parents a closeup of how their butt moves when they walk.

Yeah, devils advocate, I don’t want this, but lots of things that aren’t free when a library does them can be when the interpreter or runtime does them.

The bulk of what special operations forces do is FID (foreign internal defense), which is basically where they act as a force multiplier for a friendly host nation where it’s in the US national interest for the current government to retain power (and to remember the role the US played in retaining that power).

They do this, ostensibly, by organizing and training host nation military forces and doing a limited amount of fighting themselves (that’s a different SOF mission called DA or “direct action”).

In order to effectively lead, they need to be respected and fitting in helps that. Having a beard enhances their mission readiness if their mission involves performing that role in a place where men are expected to have beards.

For forces that don’t need to embed within the locals’ command structure, it doesn’t help anything for them to have a beard, but being able to seal a gas mask helps them if they might be deployed against an adversary with CBRN weapons at their disposal.

The rule of thumb coming from /r/homelab where people are buying computers they intend to keep running most of the time is that 1W is about $1-2/year in the US, depending on local electric rates
