To expand on this, this is not just about verbatim memorizing discrete facts - algorithms, definitions, dates, events, vocabularies, grammar rules, musical notation,... - it's about learning when and how to use or apply them.

Facts become information, information becomes knowledge. Learning is about processing what's in front of you. Becoming aware of facts presented to you in a book or a powerpoint presentation, then reflecting on those facts, turning those over, engaging with them, asking new questions, trying to apply them in different contexts and so on.

As you do that, the entire experience of gaining knowledge also leads to self reflection. That is, learning to know yourself. And others around you. When does it matter to apply what you know? When not? What is relevant to me and to those around me at which point? This is about learning to formulate effective critical argumentation based on what you know. And that involves challenging viewpoints including your own. Context matters.

The latter is a skill. It's something you need to practice if you hope to be any good at it.

Expanding on your example:

I think it's important for engineers to have a proper understanding of the details about nuts and bolts when they are actually building the Eiffel Tower. But in a meeting with stakeholders - the mayor, city officials, banks, sponsors,... - it's also about knowing that they probably don't care about those material aspects. Unless the context changes and those become super important. Like when it becomes appartent that the iron wears out because of changing weather conditions. And even at that point, those stakeholders likely aren't interested in the exact chemical formulae that explain the process unless it's necessary to cover risks and liabilities. They simply want a good, terse explanation from an expert and an assurance whether it can be solved.

Hence why knowing things isn't enough. It's about knowing how and when to apply them effectively.
Yes, being able to offload less relevant, less frequently access and intricate information is very useful.

However, the reason why it is so useful is because it gives you more room to use for the stuff that really matters.

Knowing stuff has much lower latency than looking stuff up and having the ability to quickly correlate multiple relevant facts and draw connections allows for much higher capabilities and productivity.

They key is figuring out which stuff you need to know to be able to quickly build and evaluate mental models and which stuff is best looked up.

Even if advanced machine intelligence could generate explanations, does that really establish trustworthiness? We can't even trust humans to explain their actions reasonably well. We're usually way better at rationalization than we are at introspection. How are we to know the same isn't true for the artificial intelligence?

I believe it can be, I find that explaining things using animations and being able to use a more casual tone while narrating can be helpful and easier to follow.

I've already tried writing a PlayStation emulation guide: https://github.com/simias/psx-guide (only covers the very basics unfortunately). I found that in order to really get in-depth I had to write big walls of text to explain relatively simple concepts. Being able to talk more casually and expressively over illustrations can be less daunting for somebody looking to get into emulation.

Regarding your edit: I already took a bunch of notes while actually implementing the emulator so I have a fairly clear idea of what my script will look like (i.e. Intro -> CPU instructions -> timings -> basic GPU -> controller input -> sprites -> sync to real time -> etc...). I won't focus on the code too much because it's not a programming tutorial, it's meant to me an emulation tutorial. It would be targeting people who already know how to program but might not be comfortable in the low-level and don't know where to start.

I agree that NAFTA is one major inflection point, but it supports 25 years ago, not your 10-15. I mean, I'm in full agreement that the democrats as a party have abandoned anything but the neoliberal project - I just also think if you expect anything but isolationism and racism out of the GOP - neither of which is good for the working class - you've fallen for their big lie.

> I think Southern racism has very little to do with the Republican shift in the Midwest.

I didn't say "Southern racism", I said "Southern Strategy", which is a specific GOP maneuver to pick up white working-class voters from the 50s onwards, as they calculated it would be better to give up the black and civil-rights focused voter base they were already losing, to pick up the white working-class, primarily agricultural, voters alienated in the South. They used existing racism, but they also stoked it. It was extremely effective (to the point you can even use "Southern racism" as a shorthand and "everyone knows" what you mean). While they mostly couldn't predict a similar opportunity in more industrial labor in the north 2-3 decades later, they definitely didn't miss the chance when it arose - and again, they've used existing racism, but also heightened it in places it was previously marginal.

My biggest peeve is the length requirements with writing. There's no need for fluff unless you're going into literature. People need to learn how to succinctly get their point across.

I remember we'd have reports where we need to write 10 pages and I would finish everything in 4 pages and have no idea what to do after that and then it just becomes a game of bullshitting to draw it out.

Same thing with essays where it needs to be a page long and I'm able to answer on a paragraph.

The benefits of this diet seem to come from lowered blood sugar and a capacity to produce ketones that affect cellular signaling in various ways. The fact that you were doing so much aerobic activity tells me you probably had low enough blood sugar and high enough ketone synthesis rates that the dieting was redundant. Most people don't work out aerobically like that.
Oh, another person telling the world what devops means.

If we take the 50 thousand or so other blog posts about the definition of devops and glue them together - it means whatever you want. Ops teams doing some code, devs building CI/CD infrastructure, whatever.
In my field, computational chemistry, you are definitely right: when we have more parallelism available, we go for increased accuracy and scope, not reduced latency. The latency is set by human schedules (a coffee break, overnight, etc). So Amdahl's Law does not apply.
>Why not? It's unlicensed, so it's a free-for-all.

Unlicensed doesn't mean no rules. For example, even though 2.4 Ghz is unlicensed, you're still subject to transmission power limits. In the US at least, there's also statues against interference.

I think that the idea behind all of this is sound but that at some point we will have to accept that there always will be some remnant of insecurity unless you are willing to create your own fab or build your CPU up out of discrete transistors which can be (1) exhaustively tested and (2) are too simple to contain anything nefarious given that there is no way to know where in a circuit that transistor will end up.

So the bioprinting is an alternative means to construct a replicate tooth (as opposed to CNC milling).

Replicate teeth can be used as a less invasive/quicker healing alternative to implants under some conditions:

https://www.replicatetooth.com/for-patients/

"The REPLICATE System can only be used if the root of the original tooth is still in place. Also your dentist will need to evaluate if the surrounding bone structure is healthy enough to accept a REPLICATE Tooth."
Or your temperature sensor being rendered useless via a clever attack?

Perhaps by something as simple as by a clever pattern of temp sensor reads causing your code to think temperature is in safe range for your application?

Or causing your code to execute extra multiplies to generate heat to hide a momentary temperature drop.

My point is even if you could 100% trust your supply chain and 100% validate your silicon matches your design, there are still residual issues.

For example, power supply glitch attacks [0] are nowadays well known, including techniques to make them sufficiently reliable.

I know the process, a bit. The way I see it is: first you _follow the recipe_ , until you think you understand it and are getting reasonably good results.

Then tweak it and take notes of the resulting improvements or setbacks. Repeat for life. As you say, it's iterative and multi-dimensional.
> The market has spoken.

The market “demands” cheap, turnkey, easily replaceable programmers who don’t really know what they’re doing, and justifies this with “I made a website last weekend, programming is easy, you’re just pretending its hard to keep out competition”. Until software engineering is treated as actual professional engineering, time, money and resources will continue to be wasted frivolously.

You can change the default.
Do you have a link? I’m pretty interested in this field, and as far as I know all the 3D printing tooth companies are just using the same old materials. Most labs can already CNC you a tooth the same day. All of the “bio-printing” stuff I’ve seen thus far is marketing BS.
That's because you are ignorant of radio frequency technology, circa 1940. The only reason a shared frequency band like 2.4 GHz works at all is because we have invented technology that can implicitly synchronize with other senders through avoiding collisions with ongoing transmissions, e.g. through CSMA/CA. Obviously a band like 2.4 GHz will simply not work if devices were allowed to transmit permanently like an analog radio. And so out of simple necessity the regulation for shared bands has very broad language to the effect that you can not interfere in any way with others operating on the same band.

> This is just called skipping breakfast. But I guess there was a need for a new fancy term for an old thing.

On the contrary, we need to be reminded of what we've forgotten; and the proof is in the word itself: "break fast" literally means to break your overnight fast. Our forebears understood the concept of "fasting until your first meal" very well.

The fact is that it's almost certain that for the vast majority of people, until the 20th century, "intermittent fasting" was just called "life". Our hunter-gatherer ancestors couldn't count on three solid meals a day, and even the best-fed would almost certainly have gone into periods of "fasting" several times a week just because of the way life was. A few hundred years ago, many people might have their first meal at 10am (after a few hours of work), and their last meal at 4pm.

And that's exactly why it's actually quite healthy. Your body is designed to fast (i.e., run out of glycogen and have to rely on ketosis), the same way it's designed to exercise; and going through life without any fasting turns out to be as harmful as going through life without any exercise.

But the good news is you don't need to do 36-hour fasts to get at least a bit of health benefits, just like you don't need to go running to get health benefits from exercise. A good brisk walk is way better than no exercise at all; and a 16/8 fasting schedule is better than eating constantly from the time you wake up until the time you go to bed.

This was my experience when I jumped on the Paleo bandwagon about 10 years ago. Prior to that carbs were a substantial part of my diet. English muffins, bagels, toast and cereal in the morning, sandwiches for lunch and bread as part of every dinner, along with more cereal as a nighttime snack.

After cutting all that out my energy levels were much more even. It was like night & day. I also dropped several pounds over the course of the first month. I'll occasionally treat myself to bread/carbs but nowhere near to the degree I used to.
> still ambiguity around "DevOps" so many years after its introduction.

With these things, the ambiguity ramps up over time. e.g. "Agile" used to be well-defined. Now it means almost anything, or nothing.
Eh, it's not so much trying to be smart and more trying to be unique I suppose. I guess I could've named it "my-gameboy-emu" but I'm always a bit wary of using copyrighted names in emulation projects, probably more out of superstition than anything else to be honest.

If you have an other proposition I'm all ears, I don't really care for the name to be honest. Open an issue if you want.

The instruction set architecture has no concept of it either, nor about instruction level parallelism, branch prediction or speculative execution. There is no way of getting this right other than knowing about how the processor is implemented under the hood and issue the right assembly based on that. Often experimentation is needed to get it right.

To fix this, the instruction set need to be changed, and this need to be kept in order to keep it compatible with earlier versions. Thus the instruction set remains as it is with the exception that new instruction may be added.

Are there any active studies on intermittent fasting in healthy young adults? (NY area)

I’m interested in intermittent fasting but I’d like to objectively track the effects beyond fat/weight loss. For example: ketone body blood concentration, respiratory exchange ratio, heart rate variability, etc.

There are plugins that can do that. It's called spice[1].

IF is actually very binary, you just don't eat when you're fasting and eat whatever you want when you're not. (But try to keep it under 600 calories if you're a man, 500 if you're a women. And of course the healthier the food the better, think fish, greens, etc.) It's that simple.

I like OP's point, this diet works and it can't be sold to people en-mass which causes confusion when different retailers put their own little spin on things. Most fad diets are confusing, hard to follow, and sold to you. IF is none of those things.

Yes it uses the K20, I think you may be confusing the threat model here. If you grounded the 6 capacitive touch buttons the device would not work at all so there would be no need for an RNG. The RNG is used for things like creating keys, in order to get to the point where you are creating keys you would have to be able to enter a PIN on your device by physically touching the capacitive touch buttons. As you do this the readings from your skin is input to the RNG. I hope this explanation makes it clear why this attack isn't possible.

"water or broth"
This is one of the better election hacking stories and possibilities I've read about. Most people are (understandably) fixated on hacking that would tamper with the actual voting results. But I remember the poll book software and laptops (which we use to check whether someone is a registered voter, and their current voting status, before giving them a ballot) being a conspicuous and clunky black box. Not egregiously moreso than any proprietary Windows app, but someone compromising the app or the voter data (which in Cook County, IIRC, is done via on-air wifi updates) would theoretically be hard to detect. In swing districts, making it harder for 10% of one party's voter roll to cast votes would have significant impact.
