Food (calories in) is just a form of energy your body is capable of utilizing. Fat is just a physical medium to store energy for use in your body. For your body to move and perform actions (live), you require energy. All things considered at this scale, if you expend more energy than you consume, you'll ultimately either die (due to lack of energy) or use other forms of energy in your body (e.g. fat).

This is of course the 30,000 ft view and there's a lot of complex biology and chemistry going on but it's pretty straightforward if you believe the law of conservation of energy is correct and our bodies aren't doing some sort of nuclear physics to process energy and instead relying on various forms of chemical and physical energy.

As you point out, it's not so cut and dry though in practice. There's a time component here and our bodies get quite clever. We build up efficiency of certain tasks over time requiring less energy usage. We resist building muscle because it requires more energy to maintain. Some food's energy density isn't perceived very well by our bodies and we remain more or less hungry irrelevant of potential calories making it more difficult to maintain a calorie deficit/diet based solely on our bodies senses. Many nutritional information products don't accurately measure calories of food, sometimes making it difficult to use as a base metric (theres a lot of errors in these measurements, especially by small food producers/providers). We also have incredible difficulty trying to estimate how many calories our body is actually expending because it's a fairly complex system (the "calories out" part of the equation) although there are some figures out there to help you estimate these within some general ranges depending on factors like age, diet, fitness, activity and so on--it's not perfect but it's something to work with quantitatively.

The benefit of calorie counting though is that there are fairly basic physical and chemical principles at play that make it a useful tool in weight loss and management. Even if a bit variable (both the in and out) and sometimes inaccurately represented, it gives us something fairly quantitative to work with, measure, and change around to control our weight. We can measure it and change other variables in our lifestyles to, over time, manage weight. It works and the statement is valid but it's not simple to use by any means, there's a lot one needs to learn over time to better learn how to measure their in/out and overall body feeling based on these factors.
NeetCode has created a good website with a list of 150 practice questions that you can go through. The list contains links to his very explanatory walkthrough videos and code for (the solutions to) the problems. I'm not sure that you would get the best ROI from an online university course, but it might depend on your timeline (i.e. if you are actively preparing for an interview).

50W is barely moving on a bicycle.

But 500W is a significant effort for an untrained person, particularly somebody of smaller stature.

FWIW, I'm an avid recreational cyclist and my 1-hour power fluctuates in the 250W-280W range at 68-70kg body weight. My all-out sprint power is over 1000W, but not by much. 2000W is enough to win elite sprints, both on the track and on the road.
Absolutely ridiculous to call this a “meme”. It is the most basic fact about how to lose weight. Stop eating altogether and see what happens (spoilers: you’ll lose weight as your body devours itself because your body needs calories to operate)

Yes, indeed! Children have a huge capacity for stories that engage their imaginations, creativity, and open sense of wonder. And, I think if we're honest, kids are often more honest critics than adults.

Author of "A Wrinkle in Time" Madeleine L'Engle said, "You have to write the book that wants to be written. And if the book will be too difficult for grown-ups, then you write it for children."
Following the terminology of the article, CA and AC are two different stacks (C calling A vs. A calling C) so they cannot be merged. Instead, the whole flame graphs form a vector space, with a dimension for each stack (with the provision that for many purposes only the positive cone makes sense). There is no meaningful operation between stacks.

A lot of middle and upper management pays lip service to increasing value for the investors, but they don't really care for the investors any more than they care for their employees or their customers. It's better for them to be paid in cash and be ready to jump ship at the first sign of trouble than the much riskier course of counting on long term growth of their present company.

I worked briefly on Fuchsia and LK (little kernel), years ago, as a contributor.

First of all, Fuchsia is SMALL. I mean it could easily be maintained and developed by 50 people. The kernel is tiny despite being of many modules and so is the application layer. I don't see any problems wit the 16% lay off.
I like this idea, but isn’t this a recipe for only ever doing the urgent stuff, not the not-urgent-but-important stuff? For example, if your list had “read 1 chapter of SICP” on it, you might never get to it.
It looks like they made people do things that require more short term oxygen uptake and as a result they adapted to be able to uptake more oxygen in the short term. I wouldn't so readily dismiss the myriad of other physical adaptations that result from long term, high volume, low intensity exercise, such as improved bone density, better fat metabolism, stronger heart muscles, better endurance and resilience, better mental health and cognition etc.
I wrote a few children's books when these tools first came out, but ultimately I decided against publishing them due to ethical concerns. I couldn't quite put my finger on it, but something felt dirty with the act of publishing and profiting off this work as my own.

That said, it was a very fun exercise and I look forward to the stories that are created in the future where the authors don't have the same hang up I did. Even if you don't publish, I would recommend going through the creation process at least once to familiarize yourself with how simple it actually is (tedious, but simple) to create this type of work.
There are so many video ads on that page. I couldn't read the article; it was too distracting. Ars sure has changed.
A smartphone is pretty similar in wealth terms to owning sofa/couch. They're about the same price new, they each make your life a bit better but encourage some bad habits and they each rapidly devalue second hand. I wouldn't say owning a sofa makes you rich, even owning a nice one. It might mean you're a bit sloppy with personal finance but what's a grand between billionaires? And smartphones even have much more favourable financing options.

I think the thing is with smartphones that they're clever but they're not that expensive. A lot of what makes them special is just derived from sand one way or the other. Compared to renting an apartment, your phone barely registers on your finances, it's usually at least an order of magnitude out even if you're in a cheap place and have an expensive phone.

Yet housing is the real necessity, why hasn't capitalism made that cheap yet? It feels like a case of bad incentives. Which is not to say that communism would do any better, I'm well aware of its pitfalls. But I think the idea that capitalism makes everyone rich is also a bit absurd.

There'll be a lot of low effort stuff but there's also going to be a torrent of good work done with it. A lot of people seem to be missing the developments in these tools that allow you to take the initial result and then shape it through further prompts or by running it through other tools. If you're willing to put the work in to guide and polish the result you can produce some pretty good work with much less effort than it would normally take.

Thank you very much for your time and feedback! Your experience with Refine is inspiring for us. Can you tell us exactly where we lost you? Was the learning curve too steep or were you unable to accomplish what you wanted to?

To be honest, we are working very hard to not let the experience you had to be felt by developers and it is clear that we need to work more.

Thank you for giving us the opportunity to improve ourselves.
Beautiful.

So can people upload their code snips to the appstore such that, say, a marketing data analytics person with no coding experience can pay to get 'buttons' to run queries that are relevant to their needs?

like the salaries example, for example, I used to spend a shit-ton of time educating a CFO on AWS spends in excel.

If I could have a code snip 'button' to use some AWS-CLI creds to pull results directly from AWS asa "CFO BUTTON" and set them up with an easy export to an XLS - and then let them build their own dash to their choice that would be cool.

I havent looked at Cloudability in quite a while, (know the founder) -- but giving a CFO-type an excel button... Every CFO can navigate excel. so they get an invisible tool that empowers them, and relieves stress on the Ops team...
I'm in the same boat. I have dual 3090s for gaming and AI, though I rarely ever utilize it for either anymore.

I originally tried to stick them both in my pretty large case from BuildRedux, but it would overheat and shut off, so I just bought a mining "case" - basically flat steel bars rivetted together. It can supposedly hold 8 GPUs, but I only have my 2 3090s on it and even then, when they are both working on something, it kicks off a LOT of heat, but with a fan blowing on it, the GPUs never reach critical temperatures.

Last winter, I had it in stored in my AC return closet, and used it for crypto heating, and my AC/Heat was just set to circulate. Kept our apartment at around 70F even when it was in the 30s and 40s outside.

This is kind of a tired reasoning. I don’t know what the goal of this kind of reasoning is. The fact is that virtually no one learns or dies art this way. No one in any statistically meaningful amount has a photographic memory and uses such memory to create new art stroke by stroke.

In rust you can use these almost everywhere in place of an expression (if statements, while loops, in function arguments, etc). It can sometimes make code a bit unreadable to some people, but its still a cool feature imo.

The standard recommendation is to buy an Ender 3, but it’s very slow by today’s standards. I’d recommend Flsun V400, it prints almost as fast as the state of the art, but has no proprietary components, and comes (almost) pre-assembled.
This predated a lot of the responsible-disclosure culture that exists now, so there was a lot of “find vuln, post right away for the credits” going on. Couple that with a lot of tool research that was important but also felt very grey-hat, and it was easy to feel like much of the “vulnerability research” community were like a group of scientists working on making cancer airborne “for research purposes”. I admit to having felt that way then, too.

Fortunately a lot of that has subsided. The focus on responsible disclosure while still holding companies accountable, the great security research being done by projects like Talos or Project Zero, and the consistent flow of new open-source blue-team tooling has really helped balance the scales (if they were ever unbalanced).
The way most energy companies work, they do indeed 'pay for readiness' - ie. they'll give you money simply to be available to deliver power, even if you are never asked to deliver power.

That is also usually a market - ie. power stations can bid to provide that service, and the lowest bids are selected.

The only thing missing is that little residential guys usually aren't welcome to bid... Usually there is something like a 5MW minimum to play the game.

How to Be 18 Years Old Again for Only $2M a Year
And I imagine they add new domains with updates all the time.

At home I was trying to avoid random reboots from updates in a full proof way in a Windows VM that ran long processing tasks. I determined the only reasonable course of action was to remove all internet access. Stamping out the massive list of changing domains (and hard coded ip addresses?) would just be to much work that I know I would never keep up with.

A white list might work.

I mused that you could have a constantly updating Windows machine and monitor all of its connections, adding them to a block list on an external firewall but in addition to being complex to setup I bet it wouldn't even catch everything.

Car batteries are not really comparable to cellphone batteries. Even among "lithium" batteries in cars there are multiple chemistries with different longevity and trade-offs (e.g. LFP can be kept charged at 100%, while NMC would rather not).

1. Cars have advanced battery management system with heating and cooling, which noticeably improves the battery life (e.g old Teslas have lost 1%-2% capacity per year over a decade, while Leaf about 3% per year, most likely due to lacking liquid cooling).

2. Cars won't let the battery discharge to 0%. Modern EVs even have an inaccessible reserve, so that when the car shows 0%, it's actually ~5%. Cars with vehicle-to-load/vehicle-to-grid typically stop giving power at 20% state of charge. Slowly cycling around 50% is quite gentle for the battery.

3. The grid just has to pay more for the storage than the cost of battery wear. The "duck curve" means they'll want to pay you to take electricity off of them at noon, and pay you a premium to get it back in the evening peak time.
I have the same question: People often calculate with calories as if it is really simple math. But - honest question - does my body really have to suck up every calorie or could it excrete some calories in the toilet and also vary that amount depending on my caloric intake? For example, I have read somewhere that you urinate superfluous proteins - which also have calories.
Also, if I'm hungry I get cold. I might put on another layer. So my "base energy expenditure" could vary with the amount of calories I eat, right?
Of course at some point in the future if a lot of people with EVs say yes to this deal, the price range will narrow significantly, and eventually stabilize to the point where it's only just profitable given battery degradation costs. But it may take a long time to get to that stage.
>>An intern can only be unpaid if they are not doing productive work and you have a trainer with them.

I mean yes, but like you yourself acknowledged - that's a completely meaningless law. No intern is going to report this, because young people are just happy to have a job, no one wants to destroy their career right at the start. I myself was in that exact same position when I started - as an intern, my contract specifically said I can't be doing any productive work. Of course I did anyway. And I'm sure it still happens in every industry, because.....why wouldn't it. That's why I think unpaid internships just shouldn't be a thing at all, anywhere, unless linked to vocational schools that oversee them as a training programme.
Why not just go through them in one go and be done with it?

They probably already were out in the wild.

It seems hard to believe but back when people had landlines, just about everybody was listed in the phone book -- name, address, and phone number.
Many restaurants in our area are "removing the middle man" so to speak - with modern technology, the waiter isn't a necessary component, as ordering, paying, etc. can all be done either through a smart phone or a smart display at the table. A server is still somewhat necessary, but requiring someone who is highly sociable or remembers orders well is no longer needed.

Of course, nicer restaurants will retain waiters because it is nice to be waited on by another human being, but you need to pay for that experience!
Yea I’m with you. If a children’s story is primarily a generic - albeit engaging - plot, then I think AI will be very successful at telling new stories.

But as a means of cultural encoding to help children understand what matters in the world and how they - specifically - fit into that world, it’s going to come up short.

> instead of a single top up change it is now constantly discharging and charging

This is where V1G beats V2G.

V1G (AKA grid-adaptive charging) just chooses when to charge the car, to efficiently spread out the grid load overnight and spatially across the network. No extra charge cycles, in fact it's probably more mild than just charging at full speed.

The key is that you need a UI setting for "Immediately charge to X%" and "Charge to Y% by Z:00." This avoids the problem where you find yourself without enough charge to get to work (or the local hospital).

> you will now see multiple 0%-100% charge cycles daily.

Even for V2G, why wouldn't there be a depth of discharge slider?

> if its lifetime will be shortened... then electric company need to compensate owners

Or better yet, owners set their car to only "bid" for a grid storage job when the cost-per-kWh is greater than the cost of degradation.

This should be the default after enabling V2G.
The measures that improved are more important then body mass itself. Body mass is an aesthetic measure. The improved measures were directly related to the health. And "fitness" itself is measured by performance, not by how you look like - which would make it third measure.
This can be done by using a smart AC charger.

In europe (At least) the company Easee makes AC chargeres that are WiFi / 4G enabled. In Sweden (And Norway) you can connect them to a service like Tibber, which allows you to automatically enable/disable charging with the electricity price, assuming you have a spot price electricity contract.

https://tibber.com/en/product/easee

Easee chargers also have a pretty bitching API, so you can also make your own automations using e.g. home assistant or what have you.
That’s actually a good point. It is very much a non-trivial ability.
According to https://layoffs.fyi a company named “GoTo Group” based in Indonesia recently laid off 1200 employees, however they appear to have no obvious relation to “GoTo Company” which owns LastPass.

Does anyone know what the situation is like inside LastPass headquarters?

YES. I have the dubious honor of needing to use at least 4 different Teams tenants over the course of a week and it is enough to make me want to pitch my computer into the sea. App, browser, private browser - doesn't seem to matter. When I try to sign in, Microsoft will pick one of the tenants seemingly at random, regardless of what URL I use, and try to sign me in - of course, since there is usually no visual cue as to which tenant I'm looking at, I just put in a password and pray.
It worries me that if industrial-purpose batteries cost the same and have similar degradation, grid services will also decide not to charge/discharge if the profit is less than 8 cents.

This tells me that Li-Ion batteries are far from the ideal medium for grid storage.
My point is mainly that there are plenty of options available to stabilize grid prices that are way cheaper than using EV's. Europes energy crisis is temporary, over time the price fluctuations will go down.
